Adults with asthma are at increased risk for pneumococcal diseases, which are caused by the bacteria Streptococcus pneumoniae. These diseases include things like pneumonia, meningitis, and sepsis. Luckily, there are pneumococcal vaccines that can be delivered via simple injections under the skin or into the muscle that can potentially prevent these diseases.
The Centers for Disease Control and Prevention (CDC) recommends that all adults between the ages of 19 and 64 who suffer from asthma get the pneumococcal vaccine and that those older than 65 get 2 such vaccines. Nonetheless, according to a new study published in the American Journal of Preventative Medicine at the end of September, only about 50% of those with work-related asthma get the vaccine.
The study aimed to determine what percentage of people with different types of asthma actually get the pneumococcal vaccine as recommended. They were particularly interested in the difference between those with work-related asthma and those whose asthma occur independent of their work. The researchers analyzed national data from the years 2012 and 2013 and found that while overall, adults with asthma got the vaccine at a rate of about 50%. However, the likelihood of getting the vaccine varied depending on various factors. For instance, compared to those with work-related asthma, patients with asthma that was not work-related were less likely to get the pneumococcal vaccine. About 35% of those with asthma that was not work-related got the vaccine in 2012-2013.
The lowest rate of pneumococcal vaccination in work-related asthma patients was amongst Hispanics. Only about 36% of Hispanics with work-related asthma had gotten the vaccine. Uninsured patients and younger adults (ages 18-44) with work-related asthma also had low rates of vaccination, with only about 39% and 42% getting vaccinated, respectively.
Physicians and researchers are eager to get those with asthma to get the pneumococcal vaccine. The vaccination is important not only because pneumococcal diseases can be fatal (about 5-7% of the 900,000 Americans who get pneumococcal pneumonia each year die from it), but also because pneumococcal pneumonia can exacerbate asthma. Those with asthma are also at a higher risk for other complications related to pneumococcal disease.
Research like the current study that helps to reveal the actual uptake of the pneumococcal vaccine can be used to help physicians recognize the need to educate their asthma patients on the importance of the vaccine. Future studies may also be able to help clarify the best ways to increase compliance with the vaccine recommendation.
Though children with asthma are usually advised to avoid allergens that could exacerbate their symptoms, new research published in the Journal of Allergy and Clinical Immunology suggests that exposure to allergens associated with pets - and even pests - can actually prevent the development of asthma.
Dr. James Gern from the University of Wisconsin-Madison led this new study as part of an ongoing Urban Environment and Childhood Asthma study. For this particular study, Dr. Gern and his team studied 560 children living in New York City, Boston, St. Louis, and Baltimore, beginning in 2005. The children who were studied were considered at risk for developing asthma because each child had at least one parent with asthma or allergies.
When the children were aged 3 months, 2 years, and 3 years, researchers sampled allergens from their homes. They also tracked the children to determine their incidence of asthma over the first 7 years of the children's lives. They found that the higher the concentration of cockroach, mouse, and cat allergens present in these children's homes, the lower the children's risk of developing asthma by the age of 7.
Though dog allergens alone did not seem to confer any preventative benefit, when dog allergens were combined with these other allergens, the risk for developing asthma was even lower than when just cockroach, mouse, and cat allergens were present. Cockroaches appeared to be the most powerful in staving off the development of asthma.
These findings are consistent with other data suggesting that exposure to allergens can prevent the development of asthma and allergies by training the immune system to recognize these substances as harmless. These results also point to the possibility of new preventative measures for asthma. For instance, if specific allergens or bacteria can be clearly and repeatedly shown to reduce asthma risk, this knowledge can be used in the development of interventions to reduce the chances that children get the disease.
A new study, published by an Australian team in Lancet Child & Adolescent Health, has shown that an immune-based therapy has successfully allowed children who are allergic to peanuts eat peanuts for four years without experiencing reactions. The rationale for immune-based therapies is to expose children to small doses of peanut to treat their immune systems to learn that the foreign substance is not harmful and therefore to stop reacting to it as if it were threatening.
The children studied in the new research report had been enrolled in a previous study where they received a combination of probiotics and small peanut doses. Probiotics were used as a way to enable the gut to have a higher tolerance for peanuts. In this initial study, 82% of the children who received this combination therapy experienced a significant reduction in their allergic reactions to peanuts.
The new study is a follow-up study that tracks the children from the initial study four years later. According to the researchers, 67% of the children who had received the combination therapy are still comfortable eating peanuts. When tested for peanut allergy, fewer children who had received the combination therapy demonstrated allergic symptoms compared to the children who did not receive this therapy.
One criticism of this set of studies is that the scientists only compared the outcome of the allergen/probiotic combination therapy to the outcomes associated with no therapy at all. The limitation of this design is that it limits the researchers’ ability to evaluate the impact of the probiotics.
While a number of studies have shown that exposing children to allergens can improve their tolerance for that allergen. However, the evidence for the impact of probiotics on allergies is not nearly as robust. Had the researchers compared the effects of the combination therapy to those from the immune therapy alone, it would be clearer whether probiotics are beneficial in peanut allergies. Treating one group with only probiotics may make the relationship between probiotics and peanut allergies even more clear. Future research can help to clarify the importance of probiotics in fighting peanut allergies and how and why combining probiotics with immune-based therapies may enhance the benefits of immune-based therapies.
A new review published in The Lancet has revealed that older people who suffer from asthma are five times more likely to die from the condition than their younger counterparts. Unfortunately, the rate of asthma in older adults is climbing. Though the specific prevalence is debated, up to 9% of all older adults may suffer from the condition.
Why can asthma be tougher on older adults than younger adults?
For one, breathing becomes more difficult with age, even in the absence of asthma. The elasticity of the lungs diminishes as we get older, and the muscles of our respiratory systems weaken. These changes exacerbate the breathing problems that normally occur with asthma.
Another issue is that the strength of our immunes systems can decrease with age. The relevant impact is that older adults can be more likely to suffer infections that can trigger asthma attacks. Similarly, the body’s response to inflammation changes with age, so steroids that may have worked for someone with asthma in the past may stop working as they age.
According to the authors of the review, about half of older adults with asthma are not properly diagnosed, which complicates treatment and the prevention of complications. Both physicians and the patients themselves are apparently likely to blame symptoms of asthma on other conditions. For instance, people often blame their shortness of breath on being overweight or out of shape rather than considering that the symptoms represent an asthmatic condition.
Changes in cognition and motor skills are also major contributors to the heightened effects of asthma in older adults. Managing asthma requires patients to remember to take medications regularly and to deploy those medications correctly. Asthma inhalers are notoriously misused, with patients failing to get the intended doses. As patients get older and their understanding of how to use inhalers diminishes – along with their physical ability to coordinate the different aspects of using the inhalers – the chances increase that they are not getting enough medicine.
In addition to bringing more awareness to the realities of growing older with asthma and how to avoid unnecessary complications, researchers will likely aim to develop strategies to help overcome some of the challenges older adults face when dealing with asthma. Therapies that are aimed at circumventing the specific risks associated with treating asthma in the elderly could help to minimize the additional burden that asthma brings to older adults.
Though penicillin allergy is the most commonly diagnosed drug allergy, there has been mounting evidence in recent years that many people who believe they are allergic to penicillin are in fact not allergic to it. True penicillin allergy is actually quite rare.
A study that was just published in the journal Pediatrics investigated a potential penicillin allergy in 100 children between the ages of 4 and 18. The parents of all 100 children reported that their child had a penicillin allergy, but each child was deemed “low-risk” because the symptoms that led to a diagnosis were common symptoms seen in children, such as a rash. The researchers tested all 100 children for a penicillin allergy, and all 100 children tested negative.
Why are so many children who are not allergic to penicillin diagnosed as such? The answer is that penicillin allergies are often diagnosed based on clinical symptoms rather than through allergy tests. In other words, physicians will often stop a course of penicillin if a rash, itching, or vomiting occurs because these symptoms could indicate an allergy.
Because subsequent exposures to penicillin in the case of allergy can be more dangerous, the physicians will often then avoid using these antibiotics. The children (and their parents) therefore continue assuming they have a penicillin allergy without being tested.
The biggest problem with thinking that you’re allergic to penicillin when you’re not is that you will not be given penicillin or other widely used antibiotics like amoxicillin. If you get sick with an infection that would normally be treated with these antibiotics, you will instead be given something that is more likely to have adverse side effects and is also more likely to be much more expensive.
As it becomes clearer that penicillin allergy has been over-diagnosed, some physicians and researchers are recommending that penicillin allergy tests be conducted to confirm a penicillin allergy. Confirmation may be especially important in the low-risk cases, where the clinical symptoms that led to diagnosis are relatively harmless symptoms that are likely to arise from common viruses.
A study, recently published in European Respiratory Journal, investigated the potential link between pregnant women’s consumption of certain types of sugars and the development of allergy and asthma in their children. Specifically, the scientists were interested in “free sugars,” which do not include sugars found in whole fruits and vegetables.
The researchers evaluated families with children born in 1991 and 1992 and did not find any correlation between sugar intake and eczema or hay fever. They also failed to find a significant relationship between sugar consumption and asthma generally.
The researchers did, however, find that higher sugar consumption was significantly associated with allergy and the allergic form of asthma. Specifically, the 20% of mothers who ate the most sugar during pregnancy were 38% more likely to have children who developed allergies or allergic asthma than the 20% of mothers who ate the least sugar. The highest sugar intake was 82-345 grams per day, which is equivalent to 16-69 teaspoons per day. In contrast, the lowest sugar intake was less than 34 grams (or 7 teaspoons) per day.
The identified correlation between sugar intake and allergy and allergic asthma does not mean that eating more sugar during pregnancy causes allergies or allergic asthma in children. Further research needs to be conducted to determine if these findings can be replicated.
If the findings appear robust, the next step will be to determine whether sugar can actually increase the risk for allergic conditions, or if some other factor may impact both sugar intake and allergy development. Interestingly, sugar intake in children has not been shown to impact the chance of developing allergies or allergic asthma.
Researchers hypothesizing any mechanisms that could explain a causal link have pointed to lung development and suggested that high levels of fructose could cause inflammation in the developing lungs. However, this idea has not yet been tested so there are no data to confirm or deny this concept.
Doctors and scientists have long suspected a connection between asthma and diabetes, as it has appeared that people with one of these conditions tend to be at higher risk for the other. What researchers have not been clear on is the strength of the relationship and whether asthma makes it more likely to develop diabetes or vice versa.
Scientists at the National Institute for Health and Welfare in Finland have now helped to clarify the relationship between type-1 diabetes and asthma. Rather than a simple link where the presence of one condition increases the likelihood of the other, the link between diabetes and asthma is apparently more complicated. Whereas having asthma increased the risk for type-1 diabetes by about 41% in the subjects studied, having type-1 diabetes actually decreased the risk of developing asthma. The magnitude of the reduced risk for asthma was about 18%.
The researchers investigated health records from 171,138 children who were born between 1981 and 2008. From this sample, which represented 10% of the Finnish population born in that time frame, the researchers identified 80,871 children who were diagnosed with asthma and 8,939 with type-1diabetes by the age of 16. Both conditions were present in 602 of these children.
The purchase of insulin and anti-asthmatic drugs helped researchers determine children’s diagnoses. To perform their analysis, the researchers divided children into groups based on their birth years and looked at 4 age groups: 0-3, 4-7 8-11, and 12-16. The relationships between diabetes and asthma were revealed in all age groups.
While the study provided novel insights into the link between diabetes and asthma, it also contained some limitations. For one, not all the diagnoses were confirmed. Second, there was limited information on any other conditions that the patients may have had. Similarly, the researchers did not have information on when the patients developed their conditions.
The lead author of the study, Dr. Johanna Metsala, recently presented these findings at the European Academy of Allergy and Clinical Immunology Congress. The discussion at the meeting provided more insights into how scientists can further clarify the link between diabetes and asthma in the future. Researchers are particularly interested in determining whether food allergies may also be linked to diabetes.
When most people think of food allergies, they think of things like nuts, eggs, or shellfish. However, red meat has been causing more allergic reactions in recent years, and the culprit is a sugar molecule found in red meat called galactose-alpha-1,3-galactose, or alpha-gal. The picture is complicated by the fact that people do not tend to be naturally allergic to the sugar molecule found in red meat but instead become allergic to it after experiencing a tick bite.
The tick that leads to the red meat allergy has been linked to the lone star tick, which has a white spot in the shape of Texas on its back and is generally found in the southeastern United States. Dr. Thomas Platts-Mills, a lead allergy research from the University of Virginia helped to identify this critical link after he himself developed the meat allergy.
When Platts-Mills heard that an effective cancer drug, called cetuximab, was causing allergy-like side effects in 10x more people living in the southeastern United States than those living elsewhere, he decided to partner with Bristol-Myers Squibb, the drug’s distributor, to conduct blood tests. He found that all the cancer patients experiencing this reaction had pre-existing antibodies to the alpha-gal sugar. The sugar was indeed found in abundance in cetuximab.
What was causing people living in the southeastern United States to develop this sensitivity to alpha-gal sugar? The area where these cancer patients lived mapped on to the same geographical area where Rocky Mountain spotted fever, a disease carried by the lone star tick, occurs. With this clue, Platts-Mils screened more patients with meat allergies, and his studies revealed that 80% of these patients had reported tick bites. The tick bites resulted in 20x more antibodies to the alpha-gal sugar.
While Platts-Mills’ work helped to reveal the role of tick bites in red meat allergies and the allergic reaction to cetuximab, the mechanism by which the bite confers this sensitivity to the alpha-gal sugar is not yet understood. Some researchers have suggested that a virus or bacteria carried in the tick’s saliva may cause the change in the immune system of those who have been bitten.
A former member of Platts-Mills’ team at the University of Virginia is now conducted research on mice at the University of North Carolina to improve our understanding of how ticks cause these allergies. Now that more red meat allergies are being reported outside the southeastern United States – namely in Duluth, Minnesota, the eastern tip of Long Island, and Hanover, New Hampshire, one important question researchers are interested in is whether the lone star tick has traveled to new parts of the country, or if instead ticks of other species now cause the red meat allergies. Research that improves our understanding of how exactly ticks enable these allergies will hopefully enable us to develop effective interventions to reduce the suffering that accompanies these allergies.
Women are twice as likely to develop asthma after puberty than are men, and they are also more likely to suffer from more severe forms of the disorder. More girls develop asthma than boys during childhood as well. However, doctors and researchers have not had a good idea as to why this difference in susceptibility to asthma exists. However, an international team of scientists recently published an article in the Journal of Experimental Medicine that helps to answer this question.
Given that a major distinguishing factor between men and women is the distribution of hormones in their bodies, the researchers had speculated that hormones may play a role in the different levels of resistance to asthma seen in men versus women. It turns out that they were right.
Traditionally, patients have been tested for allergies through blood draws or skin tests. Skin tests come in a variety of forms. A skin prick test, also known as a puncture or scratch test, is usually performed on the forearm of adults and on the upper back of children. The test can scan for 40 different allergies by looking for an immediate reaction to certain substances. While the test uses needles, the needles barely penetrate the skin, so the test does not tend to be painful. It can, however, be itchy. Patients must wait approximately 15 minutes after the pricks for the clinician to observe the skin and determine which, if any, allergies the patient has.
Skin injection tests, often performed for suspected venom or penicillin allergies involve using a needle to inject some of the allergen into the skin. Like the skin prick test, skin injection tests require about 15 minutes of waiting before the status of the allergy can be determined.
Albuterol inhalers are commonly used to treat patients with asthma and allergy. Specifically, albuterol combats bronchospasms that can be induced by exercise or that occur as a result of reversible obstructive airway disease. Bronchospasms occur when certain cells of the immune system, known as mast cells or basophils, release substances that cause the muscles of the walls of the bronchioles in the airway to constrict. When this constriction occurs, breathing can become difficult. Albuterol works by relaxing these muscles, thereby enhances airflow to the lungs.
Albuterol inhalers have been being recalled in large numbers in the United States. As with any recall, this action has spurred a lot of questions as to what was wrong with the recalled inhalers. Luckily, there does not seem to be anything about the inhalers that would actively cause harm to users. Instead, the inhalers contained a defect that could result in less of the drug being delivered upon use than intended.
In 2014, researchers released results from a study on a new skin patch called Viaskin, aimed at treating peanut allergies. Now, more results have been released. The idea behind the patch was that by exposing people to small amounts of the protein in peanuts that causes allergic reactions, the patch could train the immune system to get used to the protein and recognize it as innocuous. The hope was that this approach – known as epicutaneous immunotherapy - would reduce or eliminate peanut allergy by desensitizing people to peanuts.
The creators of the patch suggest that the patch should be worn for three years, but the initial study was conducted over the course of just one year. This new set of results come from an extension of the original trial and involved patients using a higher dose patch for two years.
It has long been recognized that patients who suffer from asthma may struggle to use their inhalers properly. There are a number of mistakes that people can make when using inhalers. Research has shown that patients tend to make at least one of these mistakes 70% to 90% of the time. When these mistakes occur, the amount of the drug to reach the lungs is significantly reduced. Incorrect use can lead to only 7% of the recommended dose actually getting to the lungs.
A study was recently conducted to determine how frequently and why those with asthma incorrectly use their inhalers. The results helped to clarify the specific causes and implications for inhaler mistakes. To conduct their study, the scientists placed sensors on the inhalers of 23 patients, which allowed them to keep track of details about how the inhalers were used, including how they were shaken, activated, and breathed from. The patients included in the study were diagnosed with either asthma or chronic obstructive pulmonary disease (COPD).
Last year, Mylan the company that produces the EpiPen, received a lot of backlash for its increasing prices that reportedly preventing access for a number of people who require the medicine. The EpiPen is an injectable device that delivers epinephrine to those experiencing a severe allergic reaction. In the case of anaphylaxis, when the airways are closing, epinephrine is often life saving. Consumers and healthcare providers were therefore outraged when the price of EpiPens skyrocketed to $608.61 for a pack of 2 pens in 2016.
Penicillin refers to a group of safe and inexpensive antibiotics that are frequently prescribed for an array of bacterial infections. Unfortunately, some people have demonstrated allergies to penicillin. These allergies occur when the immune system reacts to the penicillin. These reactions often lead to hives or rashes. In extreme cases, anaphylaxis can occur, which is life-threatening. Though a number of people believe they suffer from a penicillin allergy, there are recent suggestions that a number of these people do not in fact have this allergy.
There are a number of known risk factors for asthma. Pollution, dust, as well as certain chemicals increase the risk for developing asthma. Smoking, allergies, viral infections, and obesity are also linked with the chronic disease. Additionally, genetics are thought to play a role. Recently, research has also pointed to depression and anxiety as contributing factors for asthma. Insomnia is perhaps the newest risk factor to gain attention from the scientific community. Researchers in Norway have published findings supporting the correlation between insomnia and asthma in the European Respiratory Journal.
A new analysis, published in the Journal of Allergy and Clinical Immunology, compiled data from 8 previous studies that investigated a total of 1.6 million patients and found that women who were prescribed heartburn drugs during pregnancy were more likely to have children who went to a doctor for symptoms associated with asthma. The study does not provide evidence for why the association may exist and does not suggest a causal relationship between the heartburn drugs and childhood asthma.
It is common to experience heartburn while pregnant, especially later on in pregnancy during the second and third trimesters. The condition occurs when acid from the stomach leaks into the esophagus. The reason it occurs more frequently during pregnancy is not completely understood, but it is generally thought that the growing womb may be the culprit because by pushing on the stomach, it could increase pressure and lead to acid leakage. It has also been suggested that the hormone changes that accompany pregnancy could contribute to the increased frequency of heartburn.
The few scientific studies that have investigated a potential link between cured meats (including sausage, salami, and ham) and asthma have not found any relationship. A new study published in the academic journal Thorax, however, claims to have identified a negative impact of cured meats on asthma symptoms. These results are consistent with some other research projects that have found that processed meats adversely affect the health of the lungs. Indeed, cured meats have been linked to a number of health problems, including heart disease, diabetes, and cancer.
The study analyzed adult asthma patients, based on their diet, their asthma symptoms, and their weight. Researchers first collected information on the patients between 2003 and 2007 and then followed-up to see how their asthma symptoms had changed between 2011 and 2013. The scientists found that each week, the average patient consumed 2.5 servings of cured meat. Researchers divvied the patients up into three groups for their analysis: low consumers (who ate one or fewer servings of cured meat per week), medium consumers (who ate one to four servings of cured meat each week), and high consumers (who ate more than four servings of cured meat each week).
It is often claimed that food allergies have been on the rise for years. According to the U.S. Centers for Disease Control and Prevention (CDC), 4 million children currently suffer from food allergies, the most common of which are to peanuts, tree nuts, eggs, milk, wheat, soy, fish, and crustacean shellfish. However, a new report published by the National Academies of Science demonstrates that there is a lot of confusion over the prevalence of food allergies, and experts are not sure if the frequency of food allergies is actually changing.

Since 2006, labels on foods that contain the major food allergens, which are peanuts, milk, eggs, fish, crustacean shellfish, wheat, soy, and tree nuts, must make it clear that these allergens are present. As a result of the Food Allergen Labeling and Consumer Protection Act (FALCPA), these products must be labeled in the ingredients list, or else, the label must say: “may contain” followed by the name of the specific allergen. In Canada, sesame, mustard, and mollusks must also be included. The specific type of allergen, such as shrimp, must also be listed.
With the dramatic increase of peanut allergy incidence in children in recent years, pediatricians had begun to recommend that parents avoid feeding their young babies peanuts until their immune systems matured. Taking care of new babies can be stressful enough without adding the possibility of a potentially life threatening allergic reaction to the mix. However, scientific research has helped doctors realize that it may actually be a bad idea to wait to feed babies peanuts because without peanut exposure, the immune system may be more likely to mistake peanuts for harmful substances. On the other hand, if babies consume peanuts, or the proteins contained in peanuts, from a young age, their immune systems may learn to recognize those elements as harmless and therefore not react upon subsequent exposure.
Researchers at the University of South Carolina recently published a study in Allergy, Asthma, and Clinical Immunology, suggesting that exposing children to antibiotics very early in life may increase their risk for developing allergies. The researchers looked at over 7000 patients through Medicaid data from 2007 to 2009. Specifically, they compared 1504 kids that had food allergies with 5995 that did not and found that those that did suffer from food allergies were more likely to have taken antibiotics before their first birthday. The analysis showed that being prescribed with antibiotics in the first year made people 1.21 times more likely to eventually suffer from a food allergy.
EpiPens could be purchased for less than $50 in the United States in 2007. The injection devices deliver epinephrine through the thigh to combat anaphylaxis, a severe, potentially fatal allergic reaction that closes the airways. For those with allergies or with kids with allergies, having an EpiPen on hand has been a recommended precaution that has helped to reduce anxiety associated with allergies and the potential for serious reactions.
A study released in July in the journal JAMA Internal Medicine claimed that a group of asthma patients that researchers studied in Pennsylvania were more likely to have asthma attacks if they lived near fracking developments. The researchers looked at data from over 35,000 patients that attended a particular clinic in Pennsylvania from 2005 to 2012. Fracking, which is a method for collecting natural gas, is a politically contentious exercise that has been deemed dangerous on a number of counts. Many of these have been debunked, but the issue remains controversial.
In this particular study, run by a group at the Johns Hopkins Bloomberg School of Public Health, researchers found that asthma patients’ risk for experiencing an asthma attack increased four fold if their residence was in close proximity to where fracking took place. Further, the group looked to see if this association between asthma attacks and fracking depended on the seriousness of a patient’s disease. They therefore classified asthma into mild, moderate, and severe when analyzing their data.
A new study has reported that children who suck their thumbs or bite their nails may be at a lower risk for developing allergies than those kids who keep their fingers out of their mouths. This finding is quite intuitive when you consider the hygiene hypothesis. According to the hypothesis, allergies have been occurring in higher frequency in recent decades because children are raised in cleaner environments than ever before. Because of their lack of exposure to germs, their immune systems do not learn to recognize innocuous environment material and therefore overreacts to it later in life, misinterpreting the material for something life threatening.
It is perhaps not surprising that allergies and allergic diseases can have a negative impact on quality of life. Patients with these conditions can be chronically nagged with symptoms that in addition to causing discomfort, can also minimize productivity and prevent the ability to engage in certain activities. However, studies are starting to show that allergies may be specifically linked to depression.
The Utah Department of Health has just released the details of a study into a link between depression and the allergic condition, asthma. According to the Utah Asthma Program, more than one third of the adults with asthma living in Utah also have depression. Given that this rate of depression is higher than it is for the general population, researchers believe that there may be an association between asthma and depression.
More than 300 million people suffer from asthma. Though many people with the disease are able to control symptoms and disease progression, many others struggle to manage the disease. For some, the struggle is simply in figuring out the best drugs and doses to use. Others, though, seem unable to control their asthma with any of the drugs that are currently available on the market.
The London-based pharmaceutical company, AstraZeneca has developed a new drug for asthma that is showing promising clinical results for those who have been unable to control their asthma with other drugs. The company just released data on phase III studies on this respiratory drug candidate, named benralizumab. The newest studies aimed to evaluate whether the drug is effective in minimizing asthma in patients, and whether the drug is safe.
Though it is not necessarily intuitive, there is a significant amount of research that shows that the time of year when you are born can impact a number of factors in your life, including your eventual height, whether you develop diseases, and how long you live. In recent years, there has been speculation that your birth season may predict your chances of developing allergic diseases such as asthma.
In 2010, following observations that children born in the fall or winter suffer from allergic symptoms like wheezing and eczema at higher rates than those born in spring or winter, scientists in Finland studied a group of almost 6000 children whose ages ranged from 3 to 9. Of the 6000 children, 1000 had been tested for food allergies by the age of 4. When the researchers dove deeper into the details of the allergies of these children, they found that birth season predicted a number of allergic factors. For instance, 11% of children whose 11th week of gestation was during April or May suffered from food allergies during their baby or toddler years. Far fewer children whose 11th week of gestation occurred at other times had food allergies at this young age.
Asthma has been reported as the primary cause of chronic disease and disability in children. Because asthma can be life threatening, effective drugs and inhalers that are used to combat asthma symptoms can be critical to survival. However, some doctors are arguing that asthma is being over-diagnosed in children and that too many children are now using drugs whose effects should not be taken lightly.
Though the drugs used to treat asthma can save the life of someone enduring an asthma attack, they also have non-trivial side effects. The drugs can suppress growth and also suppress immune activity in the airways, which can increase the risk for respiratory infections. In addition, the drugs tend to be costly. According to some doctors, wheezing, which is a hallmark of asthma, is not always accurately identified. It is important that doctors recognize normal respiration in children if they are to distinguish asthma from other conditions or from healthy respiratory activity.
The significant rise in peanut allergies in recent years has puzzled physicians and scientists. In the past decade, peanut allergies have quadrupled in the United States. The scientific community has started to suspect that doctors’ recommendations to parents, regarding when to feed their children peanuts, could be partly to blame for the rise in peanut allergy incidence.
Doctors used to tell parents to avoid feeding their children foods that are often associated with allergies, such as peanuts, eggs, and fish, until their children were about three years old. The idea behind this protocol was that young immune systems may not yet be ready to deal with these potentially problematic foods. In 2008, however, these recommendations changed when the American Academy of Pediatrics decided that delaying the introduction of these foods may in fact increase the chances that allergies develop.
There are a number of reasons why babies may not be able to receive sufficient nutrition from breast milk. To combat the obstacle and ensure that babies are offered proper nutrition easily and early in life, formula was created. Given that breast milk is lacking in certain nutrients, formula provided an opportunity to provide babies with these added nutrients. Indeed, breastfed babies are generally required to take supplements such as vitamin D and iron. In addition, formula creators can formulate the product to address any number of health issues, aiming to provide as many health benefits as possible.
Scientists from the National Institutes of Health (NIH) have discovered a genetic mutation that causes for a very rare type of allergy - an allergy to vibration. The team of scientists, who were specifically housed at the National Institute of Allergy and Infectious Diseases (NIAID) and the National Human Genome Research Institute (NHGRI) published their findings in the New England Journal of Medicine on February 3rd.
Allergy to vibration, known as vibratory urticaria, causes sufferers to break out in itchy hives or skin rashes on areas of the body that endure vibration. Though the allergy tends to lead to only mild symptoms, for those with this particular allergy, everyday activities, such as exercising, riding in motor vehicles, hand clapping, and using towels can pose serious inconveniences. For some, the allergy to vibration can lead to symptoms unrelated to the skin, such as headaches, blurry vision, and fatigue.
Vitamin D, also known as the sunshine vitamin, has long been linked to allergies. Studies have shown that children who live farther from the equator are more likely to develop allergies and suffer higher rates of hospital admissions due to allergic reactions. From November through February, it is thought that people in the north (at a latitude above 35°) cannot synthesize vitamin D because they are not sufficiently exposed to sun.
Children and adolescents with lower levels of vitamin D in their blood are more sensitive to allergens than those with higher vitamin D levels. In 2012, a study published in the Journal of Pediatrics demonstrated that infants with vitamin D deficiency are at higher risk for allergies and eczema than those with sufficient levels of the vitamin. Further, the severity of allergy in infants was shown to be linked to the severity of vitamin D deficiency.
Scientific research has shown that having allergies makes it more likely that people will suffer certain anxiety disorders, such as generalized anxiety disorder (GAD) and panic attacks. According to a new study published in Pediatrics, children who suffer from allergies starting at a young age are at an increased risk for anxiety and depression. Specifically, seasonal allergies seem to be the culprit for this group of people with a higher likelihood for anxiety and depression, and the more allergies these people have, the higher their risk. For those allergic children who suffered anxiety or depression, the degree of anxiety or depression varied from very mild to disorders that required treatment. However, allergic rhinitis, which involves allergy symptoms that specifically affect the nose, was specifically linked to the highest scores of anxiety and depression.
Autism and autism spectrum disorder involve impairments in communication and social interaction and are thought to result from abnormal brain development. This type of abnormal brain development is most likely due to a combination of genetic and environmental factors. The rate of autism diagnosis has increased significantly since 1980, as has the diagnosis of asthma. Nonetheless, because autism is primarily thought to be a manifestation of abnormalities in the brain, its potential link to asthma is not intuitive.
Though the medical community has not acknowledged it as a legitimate allergy, people have begun to claim that they suffer from allergies to Wi-Fi. Over the years, a number of health risks associated with our smart devices have been revealed – including insomnia, neck pain, and brain changes. According to the World Health Organization (WHO), Electromagnetic Hypersensitivity Syndrome (EHS) is a disorder that involves a number of non-specific symptoms that affect those who are exposed to electromagnetic fields. The apparent existence of EHS may be confused with an allergy for Wi-Fi, and EHS has itself come under scrutiny as a legitimate disorder.
Though sesame allergies affect less than 1% of the United States’ population, somewhere between 300,000 and 500,000 people in the U.S. are allergic to sesame. According to allergists, many more people are afflicted in the U.S. today than a decade or two ago. The most common symptom associated with sesame allergy is hives, with hives, stomach problems, and respiratory problems also occurring quite frequently.
The allergy appears to now be as serious and as frequent to other common allergies, like those to tree nuts. Tree nuts include walnuts, cashews, hazelnuts, almonds, pistachios, and Brazil nuts. Further, recent research has shown that those allergic to tree nuts are at a higher risk for also suffering from a sesame allergy than those who are not allergic to tree nuts. One study found that 70% of those who were allergic to sesame were allergic to tree nuts, and 65% were allergic to peanuts. A study on children conducted in Boston determined that kids with tree nuts allergies were three times more likely to be allergic to sesame seeds as well.
Many people are allergic to insect stings, which can be associated with a number of insects including honeybees, sweatbees, bumblebees, paper wasps, white-faced hornets, yellow hornets, yellow jackets, harvester ants, fire ants, and jack jumper ants. Less often, allergies can also occur to proteins found in the saliva of other insects, including mosquitos, horseflies, and kissing bugs.
Stinging insect allergy can occur in response to insect venom and has the potential to be fatal if it causes anaphylaxis and disrupts the breathing process. This type of reaction occurs in approximately 0.4-0.8% of children and 3% of adults, leading to about 40 annual deaths in the United States. However, when it does not cause anaphylaxis, stinging insect allergy is not and manifests in non-respiratory ways.
There are a number of cells of the immune system that are involved in allergic reactions. Relatively recently, platelets were added to the list of known immune cells that contribute to the body’s response to allergens and to underlie aspects of asthma. Platelets are the smallest cells that travel within the blood and are shaped like plates when they are inactive. One microliter of blood usually contains somewhere between 150,000 and 450,000 platelets.
Platelets are traditionally viewed as functioning to stop blood flow, which they do by clumping together to form blood clots. Given this function, it is important that we have enough platelets so that we are not at risk for losing too much blood should we cut ourselves. However, too many platelets can cause cardiovascular issues. Given their role in thrombosis, or blood clotting, platelets are also often referred to as thrombocytes.
The incidence of allergies and asthma has been on the rise in recent years. Western countries have seen more of a rise than other countries. However, even in Asia and Africa, the allergies and asthma occur with higher frequency in urban areas than in rural ones.
While many medical efforts have focused on increasing access and use of epinephrine, a powerful, often life-saving allergy medication, to ethnic, racial, and socioeconomic groups that have been shown to suffer from lack of access to this important drug, recent efforts have also emphasized the importance of research that clarifies differences in allergy incidence among different racial and ethnic groups. Indeed, it seems that those of different races and ethnicities may be prone to different allergies or allergy severities. Given the distinct genetic makeup of those of different such demographics, this insight is perhaps not that surprising. Racial differences in disorders related to allergy, such as asthma and atopic dermatitis, also make the idea that there are racial differences in allergy susceptibility quite intuitive.
People who work with laboratory animals are susceptible to developing allergies to the specimens to which they are regularly subjected, a condition termed laboratory animal allergy, or LAA. Lung function and changes in the immune system have been identified in a number of such workers, and it is believed that between about 1 in 3 to 1 in 5 of those who regularly work with animals will develop these allergies within 2 years. However, females appear to be more vulnerable to developing these animal allergies than are males. People with higher levels of immunoglobulin E, an antibody involved in fighting off parasites, are also more likely to develop LAA. From an environmental standpoint, it seems that the more hours that workers tend to spend with laboratory animals, the more likely they are to develop allergies. The most common symptom is rhinitis, which involves inflammation of the nose, but asthma also often develops in these workers.
People often wonder if their loving pets are susceptible to the same allergies that they are. Though our pets are less likely to suffer from the same symptoms that we do when we experience allergies, they are in fact vulnerable to allergies. Allergies occur in pets for the same reason they occur in us – their immune systems recognize certain substances as harmful, even though they may not actually be threatening. Pets usually do not show symptoms of allergies until they are between one and three years old, and when it comes to dogs, females are more likely to display allergy symptoms than males. Certain dog breeds are also more susceptible to allergies than others. Breeds with flat faces, such as pugs, bulldogs, and Boston terriers are more likely to suffer from allergies than breeds with longer snouts. Retrievers and setters are also particularly vulnerable to allergies.
It is common for people to be allergic to pollen, and to know that pollen irritates them. What is less well recognized is that there are a number of types of pollen, which peak at different times in the year and cause distinct symptoms for allergy sufferers. Having a precise understanding of the causes of one’s allergies can significantly increase the ability to manage symptoms, so learning the differences among allergens from various plants can be extremely useful for allergy sufferers.
A first step for allergy sufferers is to be tested for allergies to try to pinpoint which particular allergens irritate them. Once those allergens are identified, people can learn about when and where those allergens are likely to strike and take the necessary precautions to avoid exposure to those allergens. Below is some information on when different pollen types are likely to impact you. Because even allergy tests cannot always determine your particular allergies, paying attention to when you find yourself suffering from allergies can help you figure out what your immune system may be reacting to.
Though people often feel that their allergies get worse every year, it is not highly likely that seasonal allergies get worse over time. It is true, however, that the severity of allergies varies from year to year. Predicting how bad an allergy season will be is difficult because individual weather events can have a significant impact on allergens. The weather, for instance, largely contributes to how long and how strong an allergy season is. Hot, dry summers and harsh, cold winters often inhibit the growth of tree and flower buds in, which can reduce symptoms for those who suffer from hay fever, or allergies to grass. Further, just because an allergy season may start earlier does not mean it may end earlier. Weather can produce a longer allergy season.
Parents and Peanut Allergies
With the growing incidence of peanut allergies and the consequent deaths that are often reported on the news, many parents instinctively avoid feeding their children peanuts, assuming that the nuts may cause an adverse and scary reaction in their kids. Even doctors themselves have been known to urge parents to refrain from exposing their babies to peanuts. In 2000, the American Academy of Pediatrics specifically advised parents to avoid feeding their babies peanuts if they were at risk for allergies.
Groundbreaking research conducted over the past five years and finally published paints a new picture of how this intuitive reaction to the growing issue of peanut allergies may actually exacerbate the problem. A study published earlier this year in one of the most respected medical journals, the New England Journal of Medicine reported that exposing babies to peanut products reduces the risk of peanut allergy by 70-86% in those infants at high risk for developing the allergy. The researchers conducting the study, led by Dr. Gideon Lack, presented their findings at the American Academy of Allergy, Asthma, & Immunology (AAAI) conference in Houston in February.
Peanut Allergy Incidence
Around 5.4 million people suffer from peanut allergies in the United States and Europe alone. Among those with peanut allergies are millions of children, who, along with their parents, have to deal with the anxiety that comes with these allergies on a daily basis. Peanuts are the biggest culprits for food allergies, with approximately 8% of American children being diagnosed with the allergy. As a society, we are impacted not only by the death that can result from severe allergies and anaphylactic reactions but also by the reduced quality of life associated with dealing with such allergies. The psychological impact of allergies on patients and their families can lead to severe anxiety and antisocial behavior.
When we think of treating allergies, we often think of pills, inhalers, nasal drops, and EpiPens. However, preventing allergies can be one of the most effective ways to deal with them. Because there are no cures or vaccines currently available for allergies, prevention generally requires controlling one’s environment. For instance, those with food allergies are advised to avoid exposure to problematic foods. Those allergic to indoor and outdoor allergens, such as pollen and dust mites, can also reduce the impact of those allergens on their bodies by employing measures to decrease the levels of those allergens to which they are exposed.
Before puberty, boys tend to suffer from allergies and asthma more frequently than do girls. However, after puberty, these conditions are more common in women than in men. Women who suffer from acute asthma, which is related to allergies, are 60% more likely than men to require emergency intervention or hospitalization. Further, women suffer more frequent and more severe anaphylaxis, which is a potentially fatal severe allergic reaction that can inhibit a patient’s ability to breathe and lead to stroke. Researchers have wondered for years why the sex difference in tendency to experience anaphylaxis exists, and recent research points to a potential role of estrogen.
We often associate weather with our allergy symptoms because certain seasons bring with them specific allergens that trigger our sneezing, runny noses, and wheezing. Often, the causes for our allergies are agents that thrive in certain weather conditions. For instance, mold grows in the winter, poison ivy is rampant in the summer, and pollen fills the air in the spring and fall. However, sometimes it is the weather itself that makes us suffer form allergies.
Specifically, changes in temperature and humidity can cause allergy symptoms like sneezing and congestion, which occur due to swelling that results from changes in the nose’s membranes. These types of symptoms are generally referred to as non-allergic rhinitis. Other weather specific conditions, however, are allergic reactions rather than non-allergic reactions. For instance, cold urticaria is an actual allergic reaction to cold weather.
Several allergy drugs are on the market. There are over-the-counter medications and prescription medications that minimize specific symptoms associated with allergic reactions. EpiPens are generally prescribed for those with severe allergies because they can reverse the life threatening anaphylactic reaction that can occur in patients with allergies. EpiPens contain epinephrine, which can stop the vasodilation that occurs during a severe allergic reaction, thereby saving the patient. Though the sequence of events that occurs during an allergic reaction is generally well understood by scientists and physicians, we have not developed an actual cure for allergies or asthma. Though there are a number of effective interventions that prevent or reduce the symptoms associated with allergies, treating the underlying cause for allergies has eluded scientists. Nonetheless, several promising lines of research provide hope that we can more effectively treat allergies in the future and possibly even cure them.
Anaphylaxis is an extremely severe allergic reaction, where the immune system releases histamine, basophils, mast cells, and other substances. The excessive reaction of the immune system to an allergen causes tightening of airways and difficulty breathing. Anaphylaxis can be fatal if not properly treated. Once it is clear that a patient is experiencing anaphylaxis, epinephrine is generally administered. People with extreme allergies often carry EpiPens, which facilitate a simple injection of epinephrine. EpiPens often save lives because there is a limited amount of time from the onset of anaphylaxis and death. For those who cannot get to the emergency room fast enough, an EpiPen makes all the difference.
For millions of people allergic to eggs, exposure to these agents can lead to severe and dangerous reactions. Children are much more likely than adults to suffer from egg allergies, and eggs are the second most common food that causes allergy in children, behind cow’s milk. In the United States, 1.5-3.2 percent of children are allergic to eggs, many of which are also allergic to milk. About half of those children diagnosed with egg allergy will outgrow the allergy by the age of 17. The American Academy of Allergy, Asthma, and Immunology has reported that of those children who do outgrow their egg allergy, approximately 45% outgrow it by the age of 5. The highest levels of antibodies against egg proteins were observed in these children around the age of 1.
These days, we hear a lot about kids developing allergies at a higher rate than in previous generations. Often, these allergies are quite serious. A common example is the peanut allergy that can be fatal if it leads to anaphylaxis, and the patient is not treated quickly enough. Given the growing number of allergies and associated anaphylaxis, many parents worry about how they can protect their children from these serious conditions.
A growing number of latex allergies are being recognized and diagnosed. It is believed that about 3 million people in the United States are allergic to latex. Those allergic to latex react to a milky fluid found in latex that is produced by rubber trees. As with other allergies, the immune system perceives the allergen (i.e. the milky fluid found in latex) as harmful. Many latex allergies are mild and may simply cause some slight irritation to the skin, termed irritant dermatitis. However, the allergy can also be much more serious, leading to hives, asthma, rhino-conjunctivitis, and of particularly concern, anaphylaxis. Because anaphylaxis is potentially fatal, increasing our understanding of latex allergy and how it may lead to this serious condition is important. Further, it is critical that people recognize risk factors for latex allergy so that they can minimize the likelihood of developing this allergy and manage the allergy safely when it does occur.
Omega-3 fatty acids are a specific type of fatty acid that are essential for a number of human functions and that can be found in plants and oils and many of the things we eat. Fatty acids provide us with energy and are essential for a number of human functions.
What are the health benefits of omega-3 fatty acids?
Asthma is the leading cause for death among children, and recent research suggests that susceptibility to asthma can be reduced with methods as simple as changes in diet. Specifically, eating more omega-3 fatty acids may improve resistance to asthma. Several studies now demonstrate that dietary omega-3 fatty acids improve asthma symptoms in children. However, some studies fail to show this beneficial effect of omega-3 fatty acids on children’s health. Genetic factors may underlie the inconsistencies found in studies analyzing the impact of omega-3 fatty acid consumption on asthma. Future research will likely help clarify when and in whom omega-3 fatty acids will improve health outcomes.
Who experiences exercise-induced anaphylaxis?
In the late 1970s, the first incidence of exercise-induced anaphylaxis was described. The patient had consumed shellfish and had a late onset reaction that was catalyzed by exercise. Since that day, over 1000 more cases of exercise-induced anaphylaxis have been reported. Research on these cases indicates that young adults are more likely than those of other age groups to suffer from exercise-induced anaphylaxis and that females are about twice as likely as males to experience this type of anaphylaxis. The cases also suggest that atopic disorders commonly associated with the immune system, such as asthma, eczema, or rhinitis, are often found in those who suffer from exercise-induced anaphylaxis and that jogging is the most common exercise type to lead to this aversive outcome.
Why Its Important to Know the Difference
Colds and allergies have a number of overlapping symptoms, including runny nose, congestion, and cough. Given that these symptoms can indicate different issues that require different interventions, confusing one condition for another can prolong symptoms and reduce quality of life for an extended period of time. Understanding the different etiologies and other distinguishing features of colds and allergies can help increase the likelihood that the symptoms are accurately assessed and that optimal steps are taken to rid the patient of those symptoms.
Donation Facilitates Important Allergy Research
Almost 40% of the global population currently suffers from allergies, and the percentage is expected to increase to 50% soon. There is no cure for allergies that is currently approved by the FDA. Stanford University School of Medicine is launching a new research center aimed at developing innovative solutions for allergies. The center received a $24 million donation, which is among the largest private gifts ever dedicated to allergy research in the United States. Of the $24 million $4 million will go toward a matching program for new gifts to the center.
The gift comes from from Sean Parker, a Silicon Valley entrepreneur who suffers from severe allergies to a number of foods. Parker was the co-founder of Napster and has also served as president of Facebook. He was prompted by Facebook COO Sheryl Sandberg to make this specific donation. Sean has landed in the emergency room over a dozen times due to accidental ingestion of allergens, which include avocados, shellfish, and nuts. Because allergies can be genetically passed on to children, Parker worries for the safety of his two children and wants to help in the global challenge to prevent, or at least safely control, allergic reactions. Reported allergic reactions to food allergens double each decade. It is estimated that about 1 in 4 people suffering from food allergies will have a potentially fatal anaphylactic reaction at some point in their lives.
These days, we're hearing a lot about the benefits of a gluten-free diet. Gluten is a protein that makes dough elastic, and it's found in many of the staple food items we consume every day. While many people without sensitivity to the substance are opting for these diets, those with gluten allergies have a more urgent reason to cut this substance out of their daily routines.
Gluten sensitivity differs from many food allergies, as it can have chronic, malignant effects on the intestines, muscles, and joints. Over 250 symptoms have been observed in patients with an observed sensitivity. Patients most commonly complain of bloating, abdominal pain, constipation, and diarrhea. This condition has a genetic origin: there are several types of sensitivity, each traceable to the body's failure to handle these specific proteins properly.
Thanksgiving is the time of year when cooks prepare magnificent feasts. Special dishes are often served that you just don't get the rest of the year. These yummy recipes are great, but you need to be careful if you have food allergies. The best way to enjoy a holiday meal is to identify allergies, make food substitutions, and communicate your needs to the cook.
Make a list of foods that you cannot eat. This will refresh your memory, and you can give the list to the cook if you will be sharing a meal at a friend or relative's home.
Dogs make wonderful pets and are found in many homes throughout the world. However, about 10 percent of the people in the United States are actually allergic to some dogs and experience itchy eyes, stuffy noses, wheezing, sneezing, and coughing when they are around them. Nevertheless, people with pet allergies still want the love and companionship provided by these animals. There are some ways to make this possible.
For starters, it's important to realize that you're not actually allergic to dogs – you're allergic to their dander. Dog hair is actually not the allergen, but it contains dog dander that people are often allergic to. Dander consists of old skin cells that are shed from a dog. Saliva and dog urine also contain dander. Choosing a dog that sheds less and produces less dander could make it possible for you to have this pet in your home. Read on for some of the best breeds for those with pet allergies.
Traveling can create unique challenges for people with allergies. Hotels may have dust mites or even mold, and airplanes and trains seem to always contain an allergy trigger. Whether it's from spending time in new places or around new people, you're likely to be exposed to something that can irritate your allergy conditions. Try a few of the following tips on your next journey to make your allergies less of an issue.
Get medications refilled before your trip. In case of travel delays, it may be a good idea to carry an extra dose of medications. Medications should always be packed in a carry-on bag or purse for easy access. Never pack them in luggage that could be lost at the airport. It is also a good idea to keep all medications in original containers to get through airport security.
We are hearing talk of food allergies more often because there seems to be an increase in allergies found in children. What should you do if you think your child might have an allergy? Stay calm and consider these important points. Don't hesitate to contact a pediatric allergist if you see serious symptoms.
If you are familiar with some of the symptoms of food allergies, you may think about trying to diagnose your child but this is usually a mistake. Common symptoms can include stomach pain, hives, sneezing, coughing, itching or diarrhea. Diagnosing a food allergy is difficult because many of the symptoms could be pointing to another problem and not necessarily a food allergy.
Parents and schools have come to realize the seriousness of treating severe allergic reactions quickly with allergy shots. Schools are taking the initiative to see that epinephrine auto-injectors are available and used to stop allergic reactions in children and staff.
Federal legislation for keeping epinephrine at schools was signed by President Obama in 2013. The Emergency Epinephrine Act provides strong incentives for states to legislate epinephrine and provide trained personnel to dispense the shots. All states except two already have legislation in place or having pending legislation ready to go. Rhode Island and New Hampshire have no legislation in place for stocking schools with epinephrine at this time.
Peanut allergies have frustrated researchers for a long time but they may have finally found a solution to the problem. Recently, researchers from the Oxford University found possibly conclusive evidence regarding the cause of peanut allergies. The results may surprise you.
People consume peanuts fried, boiled, raw or dry-roasted and they are found in a number of commercial products. Unfortunately, allergies to peanuts are quite common and symptoms can be severe. So, why do some people have food allergies to peanuts and some do not? Researchers now believe that the processing process is the key.
It has been known for a long time that Western countries have higher incidents of peanut allergies than people in East Asia. Genetic backgrounds may play a small part in whether people have allergies. However, researchers know that people in East Asia have a preference for fried, boiled or raw peanuts and Western people seem to prefer dry-roasted peanuts.
For unknown reasons, allergies are on the rise in classrooms. One in 13 children is likely to develop allergies and need a pediatric allergist. As a parent, you need to know the symptoms of allergies and how to protect children from serious illness.
Symptoms from allergies can appear in just a few minutes or take several hours before they are noticed. Mild symptoms could include difficulty breathing, hives, itching or coughing. Dangerous symptoms may include wheezing, chest pain, trouble swallowing or losing consciousness.
Breastfeeding has seen an increase in popularity in recent years, with advocates touting a number of benefits for both mother and baby. Two recent studies provide more information on the health-related benefits that many babies enjoy. Specifically, experts credit breast feeding with a lowered allergy risk and number of ear, throat, and sinus infections.
As a pediatric allergist, these findings are incredibly meaningful. Dealing with allergies as a young child and into adulthood can be a taxing responsibility, and knowing that perhaps we have some way of limiting the likelihood of that happening is reassuring for parents everywhere.
The first study presents data gathered from the medical office visits of an estimated 1,300 6-year-olds. The results showed that children who had been breastfed for nine or more months had significantly lower odds of getting an ear, throat, or sinus infection than children who had not. Doctors cited the fact that a mother’s milk provides immunologic protection that can have a lasting impact later in life.
For those who suffer from asthma, treatment is more than important–in the most serious of cases, receiving quality care can be a matter of life and death. Those with the most advanced and complicated cases depend on medication on a daily basis just to stay alive. And while a complex, customized mix of inhalers and pills can often grant relief, it may take more than that to fight this disease.
Researchers and industry experts continue to work to provide new and better solutions for patients. As new products become available, allergists are creating more and more individualized plans that give their patients a better quality of life. They take factors like age, symptoms, severity of the disease, and any potential medication side effects into consideration. Furthermore, an asthma treatment plan may be altered year to year, or even more than once per year, as new medications and other options become available.
If you suffer from seasonal allergies, you know just what a struggle it can be to overcome. Here are seven of the most unexpected factors that may be partially to blame for that runny nose or those itchy eyes:
Alcohol - The sulfites in red wine are particularly notorious for causing allergy problems, and other types of alcohol can also take their toll. Sulfites are naturally occurring compounds that appear in our favorite wines and beer.
Chlorine - When swimming or even sitting near a chlorinated pool, you are sure to inhale the fumes. Any allergist will tell you that indoor pools are especially problematic since the fumes are so concentrated.
Contact Lenses - Pollen is one of the greatest culprits when it comes to seasonal allergies. These small particles can become trapped in the eye, especially when using soft contact lenses. These are more likely to absorb irritants like smoke and pollen. It may be worth your while to consider using glasses when you’re experiencing major symptoms.
Food allergies are a growing concern across the United States. Researchers at the Food Allergy Research and Education organization have gathered important information in recent years, publishing extensive information that individuals, including parents of young children who are affected, should know about. Here are eight facts and statistics about food allergies that you may find surprising:
Approximately 15 million adults and children are affected.
This includes about four percent of adults, or nine million adults, and 8 percent of children, which represents nearly six million kids.
Traces of peanut can be particularly difficult to remove from surfaces.
Antibacterial gels will not clean all peanut residue from the hands. Only running water and soap or the use of commercial-grade wipes will do the job. Dishwashing liquid will not remove it from household surfaces, but spray cleaners and sanitizing wipes will. This is a very important fact to know because those allergic to peanuts often face life-threatening reactions when exposed to it.
Many people who suffer from allergies appreciate the arrival of rain. A good rain shower can wash away the mold and pollen particles responsible for causing their watery eyes and itchy throats. But some people have quite the opposite reaction to a heavy downpour. In fact, thunderstorms can worsen some people's symptoms.
Although scientists are still researching and debating the results of thunderstorm allergies, initial analysis reveals some interesting and counterintuitive findings. Not only can thunderstorms increase allergy symptoms among people, some asthma symptoms can be prompted by thunderstorms. This rare health problem has been well documented, yet is not as predictable or understood as other allergic reactions. Some experts suggest that the reaction may be due to an updraft in pollen and mold particles as the beating rain hits the ground. This theory goes on to suggest that these particles are smashed into even smaller sizes which, when inhaled, stick easily to the walls of the lungs.
If you suffer from allergy symptoms, you're not alone. Millions of people across the U.S. have the same issue, whether it's in response to indoor or outdoor allergens, seasonally or year-round. You may take an over-the-counter antihistamine to address those itchy, watery eyes and seemingly constant sneezing, but day-to-day life just must go on whether your eyes dry up and go back to normal or not. One of those daily tasks we all take on is driving, whether it's to work, to appointments, to the gym, to school, etc., the list goes on.
If you suffer from seasonal allergies, you may have turned to routine allergy shots to control your symptoms. Many of us have gone through the experience as a child and continue to do so now as adults. There's a new solution called rush immunotherapy that has gained national attention as a more convenient solution to the age-old problem of seasonal allergies. If you or your child relies on routine shots for symptom relief, you'll want to learn about this innovative option. Here are answers to some of the most frequently asked questions:
What is rush immunotherapy?
It is an anti-allergy plan that is given on a condensed timeline. For example, instead of a patient coming in for weekly injections for a period of many months, he or she may be able to receive the entire series in a period of just a day or two.
Allergies got you down? It's time to fight back. While you can't mitigate what's outside, you can control the inside of your home. Follow these seven tips to allergy-proof your house. Take back control of your life.
1) Change air filters as directed. People often forget this simple task, but it means a world of difference. An old, clogged filter builds up allergens over time, pumping them back into your home through your heating or cooling system. If changed regularly, a new, clean filter won't blow back allergens.
2) Ditch the drapes. Install blinds or shades instead. Blinds or shades don't trap allergens like cloth and cloth-like materials, and are easier to clean with household products.
If you have allergies, you've probably experienced most of the symptoms involved. While most people think sneezing is a common reaction, many people don't realize that it's our eyes that are also under attack when we sneeze. Itchy, red, swollen eyes are a common reaction to dust, pollen, and otherallergens that tend to crop up during the springtime. There are a number of treatments available, and allergy tests can help you pinpoint the specific problems causing the reaction.
Why are itchy, red eyes generally a symptom, and what causes the problem?
Just as any other reaction, itchy eyes are caused when the body reacts to things that are not harmful. Things like pet dander, mold, and pollen cause allergies. These substances release histamine and causes swelling. Your eyes' blood vessels can become inflamed, leaving them itchy, red, and teary.
Watery eyes. Itchiness. Trouble breathing. Some of us know much better than others that the effects of spring allergies can be very problematic during that certain time of the year. While others see beautiful sunny skies and flowers blooming, some of us are just waiting for the months to pass, so we can get back to normalcy. Did you know that some cities are much worse for these reactions than others? Take a look at some of the worse cities to live in for springtime allergic reactions.
With so much pollen in the air at springtime, people living in this southern city can find it difficult to walk outside without dealing with itchiness and water eyes. Spring allergies in Birmingham are very common.
If you suffer from allergies, you are probably curious about what exactly causes your specific problems. Allergy testing can help you to get to the bottom of the cause of your symptoms. Whether you get red, itchy eyes when you go outside during springtime, or you can't pet a cat without become extremely itchy, these thorough examinations can help you discover what exactly is causing your issue. Depending on the nature of your reaction, a different examination may be more appropriate for your needs. There are two main types of examinations that can be conducted.
For people who suffer from allergies, the home can be an unexpected source of irritants. In almost every room in your home, there are allergens lurking that can make you miserable. Here are 4 tips for combatting them in your home:
1. Is there a fireplace in your house? If your fireplace is made of wood, it can be a source of displeasures. The wood you’re using may be growing mold. Be sure to check any wood before bringing it into your house.
Scientists have studied that those who suffer from allergies have bodies that produce a specific antibody in response to its exposure to substances that are harmless in most cases; these substances can include peanuts, pollen, cat and dog dander, and more. Scientists also discovered that symptoms tend to change as people age.
As many understand today, the explanation is relatively simple. When someone is very young, between birth and the age of 18, they tend to remain in the same environment and therefore, around the same substances. Parents or other adults probably serve them the same types of food and use the same laundry detergent and cleaning supplies for most of their life, so far.
Drastic climate changes have been known to affect the environment in a great way. Most simply notice hotter summers and colder winters, but many haven’t considered the effect extreme climate changes have on allergies.
For an allergy sufferer, there is an immense amount of evidence that shows how climate change can complicate their comfortable lifestyle. Many doctors this season have reported an increased number of patients who were sneezing or complaining about itchy eyes. This can be attributed to an increase of carbon dioxide (CO2) in the atmosphere. Higher levels of CO2 is always great for plants because it makes them grow quicker, producing more. For instance, it can help a rose bush grow more flowers. However, the increased growth in plants causes them to produce more pollen and other allergens. As a direct result, the increase of pollen in the air will lead to more people suffering from allergies and asthma.
You may think the misery of the “polar vortex” winter is over, but sadly, it can still have an effect in months to come for allergy sufferers this allergy season. It seems as if the extreme cold temperatures should have killed everything, but that, unfortunately, is not the case.
Since we had extreme cold temperatures for much longer than our average winter months, it shortened the typical growing season for all of the spring plants that produce allergens. So now, the new spring temperatures, that we are all so excited for, have caused the pollen producing plants to come into bloom at once! This can compound problems for allergy sufferers. The growing season would usually take place over several weeks, but this spring and summer, it is taking place all at the exact same time.
We know you have choices when it comes to picking an allergist., and we think there are a lot of reasons to pick Premier Allergy. First, we have eight convenient locations in the Columbus metro region. This makes appointments for your whole family easier, whether you are coming from school, work, or home.
We can offer faster results with our rush immunotherapy solution. Instead of waiting weeks or months for full relief, you can ask your allergist to speed up the process. And typically, they can do it!
Have you been suffering from seasonal allergies for months or years, but were afraid to get tested for fear of needles or discomfort? What if we told you that we could give you a skin test without needles and get you results in just 20 minutes? Yes, you read that right. Our office provides allergy testing that requires no needles.
Our procedure uses small plastic devices containing a small amount of the allergen we test for. The allergy test can check for many different allergies including pet dander, local grasses and trees, molds, and pollen. Our allergist will place the plastic devices on the back and do a small scratch of the skin. The skin is then labeled so we know which allergen was tested in that spot. Then, you just have to hang out and wait about 20 minutes to see which allergens produce a welt. A welt is just a small bump similar to a mosquito bite. It may be itchy, but most patients do not experience pain from the procedure.
Food allergies are typically caused by eight common ingredients: milk, eggs, peanuts, tree nuts, soy, wheat, fish and shellfish. These foods can initiate annoying skin reactions or life-threatening breathing problems. Because of the danger posed to those who are allergic to these foods, companies are required to display allergy warnings on their ingredients list.
Milk is the most common allergy among American children. Typically, 80% outgrow the allergy by the time they are six years old. Those allergic to cow’s milk must also avoid butter, yogurt, sour cream, cottage cheese, cheese, and any other products made from cow’s milk.
Ragweed sufferers may now be able to find relief in the form of a one-a-day pill. Ragweed allergy is commonly referred to as hay fever, or by the medical term seasonal allergic rhinitis. Sufferers often experience stuffy noses, itchy, watery eyes, and congestion, sometimes so severe that they seek relief from an allergist. Midwest residents are particularly susceptible to the condition, due to the amount of pollen the environment produces. However, until now, there was no medical remedy specifically targeted at this particular malady.
Immunotherapy is a medical term for the treatment of disease by inducing, enhancing, or suppressing an immune response. Not surprisingly, this type of therapy is often used for treating allergies. While other allergy treatments only target the symptoms of allergic reactions, immunotherapy is the only treatment available that actually reduces the body’s sensitivity to all allergens. Typically, a patient receives shots over the course of six months to a year, helping to suppress the unwanted effects of pollen and other allergy triggers. However, immunotherapy offers a chance to completely change the way your body responds to these triggers.
With rush immunotherapy, a patient will receive multiple shots throughout several hours to several days, achieving a maintenance dose in a very short period of time. After the initial period of treatment, a person is able to come into the allergist’s office typically only once a week for the next few weeks, and then even less often after that. People undergoing rush immunotherapy also achieve benefits from allergy shots rapidly, typically within a few weeks.
If you suffer from seasonal allergies, you are not alone. Millions of Americans deal with the runny noses, itchy, watery eyes, and congestion due to an allergic response to pollen and other foreign bodies in the air. An allergic reaction is simply a negative response by your body’s immune system to an often harmless substance. Pollen, for instance, is in no way harmful to humans, yet millions of people each year are victims of its effects. But why do are so many people allergic to common substances such as these? An allergy doctor would say genetics are often to blame.
People who suffer from allergies understand the fear of becoming violently ill, or even facing a life-threatening situation due to minute traces of a particular substance. These substances are often otherwise harmless, or even prevalent food items. Peanuts, for example, are a particularly common food allergy trigger, afflicting millions of Americans both young and old. However, there may be a cure on the horizon.
A doctor-led research team at Addenbrooke’s Hospital in the U.K. conducted an experimental study recently that showed a small dose of the potentially lethal substance can actually save lives. Similar to a vaccine, the report posted in the Lancet medical journal stated 99 allergic children were administered a small dose of peanut powder. After a six month period of treatment, 84 to 91 percent of the children tested in the study could tolerate 800mg, or the equivalent of about five peanuts. This amount could be a potentially lethal dose to severely allergic patients, and could signal huge strides in the fight against food allergies.
Hives are itchy, red bumps that are a common condition for those who suffer from allergies. Those bumps may be quite swollen and can vary in size from being under an inch to as large as a few inches in diameter. They can appear on just about any area of the skin and may last for just a few minutes, several hours, or even days in length. Triggers include all kinds of allergens, such as such as medicines, foods, exposure to certain elements, or even genetics. However, many people confuse different types of skin disorders with hives. It can be nearly impossible to self diagnose these skin disorders because they are all characterized by raised bumps on the skin or a red coloring.
As anyone who deals with life-threatening allergies knows, allergy education is a critical part of the school curriculum. Not only do children need to learn about this serious issue, including the ability to identify it, seek help, and even treat it, but so do the adults around them. Teachers, other school staff, and parents should take it upon themselves to learn what to do when confronted by or exposed to this life-threatening issue.
Anaphylaxis is a severe allergic reaction that affects the whole body. It can be triggered by many types of allergens, including insect stings or bites, food, and certain medications. Some of the most common food allergens for kids include shellfish, peanuts, milk, tree nuts, wheat, and soy. Latex is another common trigger for anaphylactic reactions.
Natural allergy remedies are a real source of relief for sufferers of all ages. Fortunately, since they don’t involve chemicals or drugs of any kind, most of them can be used on everyone from young children to senior citizens. If you’re looking for an allergy remedy that you can try yourself at home, consider this list.
1) Saline Nasal Pot Also known as a Neti pot, this handheld device is used to flush the nasal passages. First, you fill it with a saline solution that can be purchased pre-made or can simply be mixed at home with just boiled water and non-iodized salt. Tilt your head over a sink and pour it in through one side of the nose. The water will come out the other side, flushing out pollen, allergens, and other buildup.
Asthma sufferers are on the rise: recent statistics show that nearly 17 million people are affected by it in the United States, an increase of 2.5 million in the last 5 years. Because there is still no cure, sufferers of the disease are often in search of non-traditional or homeopathic remedies that may reduce or alleviate its symptoms.
There are two types of sufferers; allergic and non-allergic, allergic asthma sufferers are the more common type. This means an attack is most frequently brought on by a “trigger,” such as dust mites, pollen, or even a food allergen such as strawberries. However, with a non-allergic condition, an attack can be sparked by exercise, strong perfume, dry air, and even stressful situations. While inhalers and medications are available to reduce and manage attacks, the best way to prevent them is to eliminate as many triggers as possible from your life.
Weather allergies are common from coast to coast, regardless of the exact climate or temperature around you. Whether it’s wet or dry, cold or hot, or anywhere in the middle, plenty of people find that they have an itchy nose, runny eyes, or show other allergy symptoms at one point or another.
If you suffer from weather allergies, don’t feel helpless. There are things you can do proactively to gain better control of the issue and get relief from the symptoms. Consider if any of these common issues describes your situation:
Many people associate allergies with the spring and summer months, when the pollen count is high and they’re spending a great deal of time outside. For pollen allergy sufferers, winter generally means a reprieve from the symptoms that plague them the rest of the year. However, many allergies actually get worse in winter because the allergens are located indoors. Common winter allergies include mold, dust mites, and animal dander.
Anyone who has ever had an allergic reaction knows how uncomfortable and even dangerous it can be to come in contact with certain allergy triggers. Whether you react adversely to pollen, mold, pet dander, insect stings, dust mites, or certain foods and medications, there are measures you can take to avoid offending substances. The key is to know what to do before you encounter these harmful elements.
Unlike seasonal allergies caused by pollen in the atmosphere, dust mites are allergy triggers that one can encounter at almost any time of the year. Symptoms linked to exposure include eye irritation, sneezing, and nasal congestion. In order to avoid such reactions, a person may want to have antihistamines and nasal decongestants on hand. It is also possible to keep these microscopic insects at bay by putting dust mite covers over mattresses and keeping all areas of your home free of dust. Carpets, couches, and curtains are places where dust mites frequently flourish.
Environmental allergies can occur at any time of the year, especially in warmer climates. Symptoms vary from person to person, but the most common things to expect include a runny nose, watery eyes, stuffy nose, and sneezing. So what causes outdoor allergies? Well, you might be surprised that they usually stem from just two things: pollen and mold.
The pollen that plants produce is transported in different ways. Brightly colored flowers depend on bees and other insects to transport the pollen so it can be fertilized. In general, these plants don’t cause issues for allergy sufferers. Other plants, however, produce a powder-like pollen that is spread by the wind. This type of pollen is likely to cause allergic reactions.
Some individuals suffer from a wheat sensitivity that is not related to celiac disease. New research suggests that this non-celiac wheat sensitivity may be an allergy. While it was formerly considered an innate immune system response, that opinion is slowly shifting.
So what exactly is non-celiac wheat sensitivity and what types of symptoms does it cause? Essentially, this term applies to individuals who cannot tolerate wheat in their diets, yet lack the intestinal damage and antibodies present in people who have celiac disease. Symptoms can include headaches, joint pain, and numbness in the legs, arms, or fingers. In other words, it affects many major organs, including the nervous system, gastrointestinal tract, and skin. Symptoms disappear completely when wheat is excluded from the diet, making it a treatable condition.
If you suffer from food allergies during the holidays, you’re not alone. The holiday season means lots of eating out, whether at restaurants, parties, or friends’ houses. For many people, all that eating out can cause a few issues. There’s no reason to limit your social schedule or suffer through allergic reactions though. With just a little planning and preparation, you can keep those reactions to a minimum and enjoy this wonderful time of year with family and friends. Follow these allergy tips so you can have joyful and allergy-free festivities:
First, don’t give in to temptation. Holiday parties are chock full of goodies that you’ll be tempted to try. If you know–or suspect–that a dish has something you’re allergic to in it, skip over it. There is always plenty of food available, so find another dish to try that won’t leave you suffering later on.
Many people have false information about allergies. They may experience different symptoms and link them to allergies when in reality there is a different culprit to blame. Some of the common myths below have been passed down for many years, but experts know there is no truth to them.
Myth: I’m allergic to foods that make me feel unwell.
Many people who think they are allergic to a certain type of food actually experience a kind of food intolerance, sensitivity, or even food poisoning. The only way to get an accurate diagnosis is to visit an allergy specialist and undergo testing.
Pregnancy can be an exciting and overwhelming time in a woman’s life. Women who are pregnant know to expect many changes to their body. During these changes, it is important to know how to manage existing conditions or diseases, such as asthma. Fortunately, there are some easy-to-implement changes that women can make at home that may help control asthma during pregnancy.
First, it’s important to recognize that asthma and allergies are often closely related. Because of this, it’s important to free the home of things that trigger allergic reactions. The most common triggers include things like pollen, mold, pet dander, or dust mites. Items that promote the growth or presence of these irritants should be taken care of appropriately. Pillows, mattresses, and box springs should be sealed up in dust mite-proof casings. Bedding should be washed weekly in 130-degree water. Mold growth can be limited by monitoring home humidity levels and addressing problem areas, such as damp basements or dirty air filters.
Most children consider Halloween one of their favorite holidays. They get to dress up in costumes, go trick-or-treating with all their friends, and of course the candy. However, if your child has a food allergy, Halloween can be tricky. Fortunately, if you follow a few simple tips, your child will be able to have a safe and fun Halloween without consuming any foods that may trigger an allergic reaction.
Penicillin and the family of antibiotics that fall under its umbrella are some of the most commonly prescribed options available in the United States. Many parents, however, may have had an adverse reaction to one of these medications themselves or may have witnessed it in their children, causing them to believe a serious allergy is present. Did you know an estimated 1 in 10 Americans claims to be allergic to Penicillin? Continuing research suggests that these numbers are not accurate, and that far fewer people suffer from a serious Penicillin allergy than is reported.
With the school year just beginning, many moms are busy preparing their children to meet the challenges of the classroom. If your child suffers from allergies or asthma, you’re probably concerned about attendance throughout the school year as well as keeping him or her safe from attacks. It’s been estimated that about one out of every ten school-aged children has asthma, and more than 10 million school days are missed each year due to this condition. Rest assured however, there are precautions you can take to ensure he or she has the highest attendance possible, but this requires careful planning and communication with an allergy doctor.
As many of us know, it can be very frustrating to experience a summer cold. From the first sign of a stuffy nose, many of us head straight to the local pharmacy to pick up some over-the-counter medication to manage our symptoms. It never occurs to us that what we could be experiencing is actually allergy symptoms.
In recent studies, researchers have found that many adults will experience allergic reactions to common triggers, such as grass pollens and mold spores, for the first time in the summer. The symptoms these allergies present are very much like those of the common cold, so it’s important to learn about the differences between the two. Before speaking with an allergy doctor, there are a few signs to help you identify exactly what’s going on.
Do you suffer from inherited allergies? Soon, an Ohio allergist will be able to help you identify your allergen risks using genetics. Thanks to collaboration between 23andMe, a personal genetics company, and the Avon Longitudinal Study of Parents and Children, our knowledge of genetic allergies is expanding.
The combined work of 23andMe and the Avon Longitudinal Study of Parents and Children yielded a new study that draws more genetic traits for allergies. They have identified 16 new genetic associations to common allergens such as pollen, dust-mites, and pet dander. In addition to these findings, they have also identified that eight genetic variations previously thought to be associated with asthma are correct.
Alergy season is starting to get worse for many allergy sufferers due to changes in the climate. According to Grist, with more carbon dioxide in the atmosphere, both the production of pollen and plant growth have increased, leading to more frustration and problems for those who are allergic. Dr. Shah, an Ohio allergy doctor, recommends coming in for testing if you are experiencing allergic reactions.
Are your allergies in full swing? You’re not alone! Dr. Shah talks with WBNS TV in Columbus about why you may be experiencing more intense allergies than normal this year. See the full segment below. This April and May, many people are suffering with allergies and asthma. Typical symptoms include itchy eyes, nasal congestion, and sneezing. Yet you may be suffering from other symptoms such as headaches and an itchy throat.
Right now, we are in the middle of tree pollen season, and that will be closely followed by grass related allergies. Heavy bouts of rain can provide some relief by temporarily clearing out the air. Allergies are not just for the summer time though. Many people experience allergic reactions in the winter due to dust mites, pet dander and dust.
When your body is allergic to a foreign object such as dust, pollen, or a certain food substance, it produces a sneeze in an attempt to get rid of the irritant. A sneeze can project out of the body at up to 100 miles per hour and up to 5 feet away from the source. Certain allergens are more widespread during different times of year, which can cause you to sneeze more in the warmer months. Tree and grass pollen are most prevalent during the spring, while weed pollen is common in the summer and fall. But, allergens aren’t the only cause of sneezing. Exercising, plucking your eyebrows, and bright sunlight are all potential triggers. Interestingly enough, you have to be awake to produce a sneeze, as it is impossible to do so while sleeping.
Spring gets the reputation of being the most beautiful time of the year because of all the flowers in bloom, but for allergy suffers, this isn’t what they think of when they realize that spring has sprung. The same bee pollen that makes the flowers grow also makes your nose runny and stuffy. Allergy sufferers experience anything from headaches to coughing fits. And with the combination of a wet winter and alternating warm and cold spells, tree pollen has been bursting forth a bit early this year.
Ohio allergist Dr. Patel appeared on Fox 28 news to discuss the upcoming allergy season. Experts predict this year to be the worst allergy season to date. There are a few reasons why you can expect your allergies to begin acting up:
- The long and wet winter set up perfect conditions for mold growth–a common allergen.
- With global warming, we are now experiencing more carbon dioxide in the air. This helps to nourish the plants, triggering more pollen production.
The urge to spend time outdoors is never greater than in the early days of spring. The days start to get longer, the snow melts away, the sun comes out and gardens bloom. But when some of us pull off our winter boots and stop to smell the roses, we’re hit with the reality of our spring: runny noses, sneezing, coughing, and itchy, watery eyes.
Cabot Rea: If you have allergies, the worst season could be on our doorstep.
Colleen Marshall: Central Ohio is a hotspot for seasonal allergies. In For Your Health tonight, Ellie Merritt is going to tell us what to expect. Ellie, I hear it’s going to be a bad one.
Ellie: Yes, allergy season comes on fast and furious and while it is chilly outside today, doctors are expecting seasonal allergies to be earlier this year. And you’re right, Colleen, much more intense. Blame the weather. Get ready for the sneezing.
Runny noses and sniffles aren’t exactly rare this time of year; colds and the flu run rampant among adults and children alike. After the twentieth sneeze or so, chances are you’ll pop a sinus pill, load up on Kleenex, and plop yourself in front of the fire to watch another holiday-themed movie. Sometimes this works, but sometimes there’s something a bit more complicated going on that might require allergy testing. Ohio has an allergen-friendly climate, and often people go years without realizing they have seasonal allergies. If a cold and sinus medication hasn’t been doing the trick, and symptoms seem to drag on for days or weeks, you may be suffering from allergies.
Just because the seasons change, that doesn’t mean your symptoms will.
Most of us enjoy summer’s perks; it’s the season of long nights, bikinis, and pints of beer on the patio. But summer is also the season of pollen, and for the unlucky among us that means sneezing, runny noses, and dry, itchy eyes. If that sounds like you, you might happily trade warm weather and sunshine for early evenings and chill winds, if it comes with the promise of symptom relief.
If you’re an allergy sufferer you might eagerly anticipate the transition between summer and fall. So when temperatures drop to the low thirties and your nose is still as red as Rudolph’s, you probably feel a bit cheated. Isn’t summer supposed to be allergy season? Shouldn’t it all be over when the ground turns white?
A link between eating, exercising and a severe allergic reaction?
Dr. Shah seems to have found just that throughout his observations and findings that he presented at the World Allergy Conference. Throughout studies of exercising without eating beforehand and eating without exercise – Dr. Shah found that patients seem to have no unique allergic reaction. Yet when patients combine eating a particular food or meal, then partaking in some form of exercise right after, an anaphylactic or severe reaction of some sort has taken place. Sparking a clue into the reason behind this happening could be the increase in blood flow and absorption in the stomach while exercising, thus bringing to life an allergic reaction.
Dr. Shah presented his findings on Food Allergies and Exercise at the recent XXII World Allergy Congress, where he spoke on the importance of waiting 60 minutes after eating before exercise.
Columbus, OH (PRWEB) June 26, 2012
In December, Dr. Summit Shah, allergist at Nationwide Children’s Hospital, was asked to present his findings on food allergies and Exercise at the XXII World Allergy Congress. In his presentation, the Ohio allergist cautioned individuals to be mindful of reactions with food allergies and exercise.
Pass the tissues. Allergy season has arrived early this Spring, bringing with it sneezing, wheezing, and itchy, watery eyes. But along with early allergies, Central Ohio is still dealing with a late flu season, and the symptoms often overlap. Dr. Shah chats about getting your Allergies under control before April arrives.
Allergist Dr. Summit Shah lent his knowledge to the folks at Columbus Parent Magazine to help clear the waters surrounding food allergies–and the verdict isn’t in yet. Even if your child doesn’t have food allergies, most parents know which foods most often ignite allergic reactions: nuts, wheat, eggs and milk. But what do you do if you fear your child has a food allergy?
When September rolls around, it usually means back to school for the kiddos. Back to school also typically means allergy season, high ragweed concentrations, and a mix of allergens all creating a disruption for your little ones and their school routine. Last week, NBC4i stopped by our Dublin office to chat with Dr. Shah about the problems of back to school allergies and what can be done to help. Ellie Merritt interviewed allergistDr. Summit Shah and gave an inside look at how a few young ladies deal with their allergies in a school setting.
Premier Allergy’s very own allergist Dr. Shah talks about the introduction of rush immunotherapy and accelerated allergy shots being at the forefront of cutting edge allergy and asthma treatment options.
The beauty of budding plants and bouquet of aromas are sources of satisfaction for many gardeners. For allergy sufferers, though, gardening can be as much a chore as pursuit of passion.
Pollen from trees, shrubs and grasses can cause an onslaught of allergy symptoms, including sneezing, itchy eyes, congestion and in some cases, an asthma attack.
As the number of people suffering from seasonal allergies rises, it’s been increasingly important to discover new ways to combat allergic reactions and symptoms. There are current medical practices and medications that can manage symptoms, but rarely does a treatment aim to eliminate the problem. A new way of treating patients with these health issues is through a new method called rush immunotherapy. This not only helps reduce the frequency of reactions or the severity of symptoms, but it has in many cases helped patients overcome allergies all together. Learn more about Premier Allergy’s rush immunotherapy allergy treatment.
Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. The reaction can occur a few seconds to as long as an hour after exposure to the allergen. It is a medical emergency, and in most cases it requires immediate treatment and then follow-up care by an allergist. Anaphylaxis is triggered when the immune system overreacts to a normally harmless substance such as food or medicines. The symptoms may be mild to severe and affect various body organ systems.
Each person may experience symptoms of anaphylaxis differently. The most common symptoms include:
- Respiratory system: chest tightness, shortness of breath, wheezing, throat tightness, cough, itchy mouth/throat, nasal congestion
- Cardiac system: low heart rate, pale/blue color, dizziness, low blood pressure, lightheadedness
- Skin and mucous membranes: hives all over body, swelling, itchiness, redness, itchy/watery/red eyes
- Gastrointestinal system: nausea, vomiting, diarrhea, stomach ache
- Other symptoms: anxiety, feeling of “impending doom”
The allergen triggering anaphylaxis can vary for each allergic person. However, some of the more common causes of anaphylaxis include:
- Foods – Any food can cause an allergic reaction, but the foods that cause the most cases of anaphylaxis are peanuts, tree nuts (such as walnuts, cashews and almonds), shellfish, fish, milk and eggs.
- Medications – Any medication can cause an allergic reaction. However, common medications that cause anaphylaxis are antibiotics and anti-seizure medications.
- Stinging insects – Yellow jackets, honeybees, paper wasps, hornets and fire ants can inject venom during a sting causing a severe and even fatal reaction in some people.
- Latex – Some products made from natural rubber contain latex allergens that can cause a severe allergic reaction in sensitive individuals.
Anaphylaxis is a medical emergency and immediate medical attention is necessary. The sooner the reaction is treated, the less severe it will become.
Those with a severe allergy may be prescribed epinephrine autoinjectors, which are shots of adrenaline that relieve breathing problems and improve heart rate and blood pressure. This medication should be carried at all times. Antihistamines such as diphenhydramine (Benadryl) may also be given for itching and hives. Oral steroids may be given to reduce further allergic inflammation.
Those with severe allergies should wear a medical alert bracelet or necklace that identifies the allergy in case of an anaphylactic reaction. Family, friends, employers, and school staff should be informed and educated about the allergy. This way, they will be able to recognize the problem and better assist if a reaction occurs.
- Regular check-ups with your doctor are very important, even if you have been symptom free for an extended period.
- Take all your prescribed medications. There are two types of medicine:
- Long-term control medications – These are taken daily on a long-term basis. They maintain control by lessening chronic inflammation.
- Quick-relief medications – These are short-acting beta agonists (SABAs). They relax airway muscles to provide quick relief.
- Children should follow a written action plan written by you and your child’s doctor. It should list what medications to give your child and what to do if symptoms worsen, including what medications to give and when to contact your child’s doctor or go to the emergency room.
- Monitor your child’s breathing with a peak flow meter. Peak flow monitoring is considered for children around 6 years and older with moderate or severe persistent symptoms, a history of severe episodes, perceived airflow obstruction, or worsening symptoms. This easy-to-use plastic device measures how well air moves out of your child’s lungs. The peak flow number and your symptoms are used as a guide to help diagnose severity.
If you or your child has had a serious reaction to an insect sting in the past, then testing for an allergy to venom is necessary. Allergy testing is performed for five stinging insects: the white-faced hornet, yellow hornet, yellow jacket, honey bee and wasp.
When most people are stung by an insect, the site of the sting develops redness, swelling and itching. However, when people are allergic to insect stings, their immune system overreacts to the venom by producing allergic antibodies called immunoglobulin E (IgE). This triggers the release of substances including histamine that then cause an allergic reaction.
Each person’s symptoms are different, but everyone must pay attention to the early warning signs to recognize that an episode may be developing. These signs may include breathing changes or coughing, feeling tired, having less energy for exercise and having lower peak flow meter numbers. A peak flow meter is an easy-to-use plastic device that measures how well air moves out of your lungs.
The most effective way to prevent stings is to stay away from stinging insects. These insects are most likely to sting if their homes are disturbed. It is worthwhile to have nests around your home destroyed.
Here are a few tips for avoiding insect stings:
During an attack, the air passages become swollen and narrow and produces a thick mucous. At the same time, the muscles around the airways become tight. The tightening of the muscles, called bronchospasm, causes the airways to become even narrower.
At Premier Allergy in Columbus, Ohio, asthma can be treated and diagnosed. Asthma is a chronic inflammatory lung disease that can cause repeated episodes of coughing, wheezing and breathing difficulty. It can be triggered by allergens, infection, exercise, cold air and other factors. It is one of the most common chronic diseases of childhood, affecting more than six million children and 15 million adults.
Avoidance is the best treatment for any allergic disease. If you avoid the allergen, you’ll avoid the allergic reaction. Diagnosis and education are crucial steps in allergen avoidance. Educated allergy and asthma sufferers fare much better than those who do not understand their condition.
If the insect left its stinger in your skin, remove the stinger within 30 seconds to avoid receiving more venom. The stinger and its sac may be removed with a quick scrape of your fingernail.
To treat local reactions to insect stings:
An allergist/immunologist is a pediatrician or internist who has undergone two to three years of special training in the diagnosis and treatment of allergic and immunologic diseases. To understand what you are allergic to, an allergist will:
- Take a personalized patient history, including a thorough record of the illness, a family history, and information on home and work/school environments
- Perform allergy testing
- Possibly perform other laboratory tests
An allergist can create a management plan with you for better control of your environment and your symptoms. Your plan may also include proper medication and, if necessary, allergen immunotherapy (allergy shots).
At our clinic in Columbus, Ohio, allergy shots will be administered to slowly reduce the severity and frequency of your allergies. Despite this, allergies cannot be totally cured. A combination of avoidance measures, our medication, and our therapies will improve the quality of your life. Call us today or submit through our one-click form to schedule an appointment!
In some cases, yes. Severe and untreated hay fever may lead to asthma, sinusitis and other serious conditions. Atopic dermatitis or eczema can spread to secondary skin infections if they are not treated properly, and untreated asthma can lead to chronic symptoms. Early detection and treatment of all allergic diseases is important.
Angioedema is an allergic reaction similar to hives, but it causes swelling deeper in the layers of the skin. It commonly affects the hands, feet, genitals and face (lips and eyes). It generally lasts longer than hives (which can occur simultaneously) but the swelling usually goes away in 24 hours. In rare cases, angioedema may involve the throat and tongue, blocking the airway and causing breathing difficulty. This can become a life-threatening emergency.
Allergic reactions can develop at any age, no matter how old you are. Since repeated exposure to certain allergens can cause an allergic reaction, it makes sense to develop allergies when you’re older, as you’ve had more time to be in contact with dust, dander, mold and pollen.
Hives and angioedema occur when histamine is released from special cells found along the skin’s blood vessels. In response to histamine, plasma leaks out from these blood vessels in the skin. Allergic reactions to things like foods, medicines, insect stings and sunlight exposure can cause histamine release. Sometimes it is impossible to determine exactly why hives have formed.
It normally works the other way around – people can grow into allergies. There are cases in which one allergy replaces another, such as with childhood food allergies. Children normally suffer from food allergies more than adults. Once they grow up, they may get rid of food allergies but then be affected by seasonal or environmental allergies. About 85% of children outgrow food allergies to milk, soy, egg and wheat, but only 20% outgrow a peanut allergy. Up to half of young children outgrow their asthma, but many find that their symptoms return later in life. For most children, eczema improves during childhood.
There are two main theories. One blames our increasing immune system sensitivity to the many synthetic chemicals in today’s society. Another theory, known as the “hygiene hypothesis,” states that the human immune system is becoming more reactive to allergens because of modern hygiene and health care. Our immune system is designed to fight off viruses, bacteria, parasites and other microbes. However, with modern hygiene, sanitation, vaccines, antibiotics and health care, our immune system does not have many invaders to fight off, and so its attention and energy are re-directed to normally harmless foreign substances.
- Acute urticaria and/or angioedema are hives or swelling lasting less than six weeks. The most common causes are foods, medicines, latex or infections. Foods that commonly cause hives are milk, eggs, soy, wheat, fish, shellfish and peanuts. Medicines that can cause hives include penicillin, sulfa medications, anti-seizure medications and non-steroidal anti-inflammatory drugs (NSAIDs, such aspirin and ibuprofen).
- Chronic urticaria and/or angioedema are recurrent hives, lasting longer than six weeks. The cause is usually more difficult to identify. Causes may be similar to acute urticaria, but may also include autoimmunity, viral infections and malignancy.
Physical urticaria is hives caused by direct physical stimulation of the skin. Common causes are exposure to sunlight, heat, cold air or water, vibration, pressure, sweating and exercise.
- Dermatographism is hives caused by scratching the skin, continual stroking of the skin or wearing tight-fitting clothes that rub the skin. These hives may be found in conjunction with other types of hives.
- Hereditary angioedema is a rare form of angioedema passed on in families. It can cause painful, non-itchy swelling of the skin, and it may involve the face, extremities, genitals, tongue and throat.
A specific allergy is not usually inherited, but your tendency to develop allergies is often passed down through families. If both parents have allergies, their child is likely to have allergies. However, your chance of developing allergies seems to be greater if your mother has allergies.
People with seasonal allergic rhinitis (hay fever) experience symptoms during the time of year when certain allergens are in the air outdoors. There are several allergy seasons: springtime, when plants bloom and tree pollen counts soar; summer, the season for grass and weed pollen allergies; and autumn, the time for ragweed and mold allergies. Perennial allergies, or year-round allergies, are typically caused by indoor allergies to dust mites, mold, cockroaches and pet dander.
About 50 million Americans, or 1 in 6 people, have environmental allergies, or allergic rhinitis. Allergic disorders are the sixth leading cause of chronic illness in the United States, according to the Allergy Report from the American Academy of Allergy, Asthma and Immunology.
An allergic person produces a specific type of antibody called immunoglobulin E, or IgE, in response to normally harmless substances such as certain foods or medicines, pollen, animal dander and mold. These IgE antibodies cause allergic reactions. If a person is exposed again to the allergen, the IgE antibodies stimulate what are called mast cells to release chemicals such as histamine to destroy the “foreign” substance.
The release of histamine causes typical allergy symptoms such as runny nose, itchy and watery eyes, sneezing, asthmatic reactions, hives, and a drop in blood pressure in severe cases. This is why antihistamines are the mainstay of treatment for allergies.
A diagnosis is usually made based on a complete medical history and physical examination. There are no specific tests for hives or angioedema. Skin testing may be performed to identify allergens. Routine blood testing may be done to determine whether any other illnesses are causing hives and/or angioedema.
The first step in treating a drug allergy is to stop the drug that is causing the reaction. Mild allergy symptoms such as hives and itching may be relieved with antihistamines. Topical corticosteroids may also be recommended. If asthma-like symptoms such as cough or wheezing are present, a bronchodilator such as albuterol may be prescribed by an allergist.
Serum sickness is a delayed type of drug allergy that occurs a week or more after exposure to a medication. The immune system misidentifies a protein in the drug as a potentially harmful substance, and it develops an immune response to fight it, causing inflammation and other symptoms.
Symptoms of serum sickness do not develop until seven to 21 days after the first exposure to the drug. However, people may develop symptoms in one to three days if they have previously taken the medication. Within one to two weeks of taking a medication, the following signs and symptoms may be present:
- Muscle and joint aches
- Swollen throat glands (lymph nodes)
- Changes in urine color
Avoidance of the allergen is the best treatment. If it is caused by a medication, strict avoidance is necessary.
Allergists may recommend antihistamines to decrease histamine release, which can lessen the symptoms of hives and/or angioedema. They may be prescribed on a regular schedule to prevent symptoms. Chronic hives may be treated with antihistamines or a combination of medications. For severe hives and angioedema, an injection of epinephrine may be needed.
Drug rashes are the body’s reaction to certain medications. The type of rash that occurs depends on the type of drug that is causing it. Rashes can range from mild to severe.
Rarely, drug rashes may result in blisters. These blisters can be a sign of a more serious condition, so they require medical attention.
Eczema, or atopic dermatitis, is a chronic allergic skin condition mainly affecting infants and children. It often begins within the first year of life, with 60% of cases occurring by age 1 and up to 90% of cases by age 5. It may last until adolescence or adulthood. If eczema is diagnosed in adulthood, it is generally a long-term or recurring condition. Fifty percent to 75% of patients with eczema may eventually develop hay fever and/or asthma.
The main feature of eczema is itchy, dry skin that scales and flakes. Often, there is a personal or family history of eczema, hay fever, hives, food allergies or asthma. When skin itchiness is not controlled, an “itch/scratch cycle” leads to continued rubbing and scratching and subsequent thickening of the skin called lichenification.
Fortunately, at long last, we now have the ability to test for penicillin and penicillin derivatives through a simple skin test. If the history and testing align, the diagnosis is confirmed in about 97% of cases. Diagnosis of other drug allergies is done mostly through a patient’s medical history. Allergists are specifically trained for this.
The location of eczema on the body changes with age. In infants and young children, the cheeks, neck, knees and elbows are typically affected. In older children and adults, the hands, feet and areas inside the elbows and knees may be affected.
Symptoms may also include:
- Dry, leathery, scaly skin
- Intense itching
- Blisters with oozing and crusting
- Raw areas of the skin from scratching
- Skin color changes
- Skin redness or inflammation
Everyone reacts to medications differently. One person may develop a rash, while another person on the same drug may have no adverse reaction. All medications have the potential to cause side effects, but only about 5% to 10% of adverse reactions to drugs are allergic. Reactions to medications can range from mild to life threatening.
A drug allergy is an allergic reaction that occurs when the body’s immune system produces antibodies and activates disease-fighting cells in response to a specific drug. In the development of a drug allergy, the immune system is triggered by the first exposure to the medication. A future exposure causes an immune response, including the production of allergic antibodies and release of histamine. So, drug allergy reactions occur after a person has been previously exposed to the drug one or more times without any allergic reaction.
There is no cure for immunodeficiency disorders. The goal of treatment is to control infections and maintain the patient’s quality of life. Infections are treated with antibiotics, which are sometimes taken on a regular schedule for preventive treatment. Patients with low antibody levels may be given injections of immunoglobulins (antibodies) to increase antibody levels.
A patient will have a comprehensive assessment, including a medical history, a complete physical examination and laboratory tests performed by an allergist. The type of infection that a patient has experienced helps to determine the type of immunodeficiency disorder.
People with immunodeficiency disorders experience recurrent ear infections, sinusitis, bronchitis or pneumonia. It is common for children with immunodeficiencies to develop thrush (a fungal infection of the mouth) and other infections of the skin and mucous membranes in the eyes, mouth and genital area. Gastrointestinal infections may cause diarrhea, weight loss and failure to thrive.
Immunodeficiency refers to a group of diseases in which the immune system does not function normally. A normal immune system will attack what is seen as a foreign invader, like bacteria and viruses. When the immune system does not work properly, a person is more likely to suffer from frequent and longer-lasting infections, often from organisms that usually don’t make most people sick. Most cases of immunodeficiency are acquired (“secondary”), but some people are born with defects in the immune system (a “primary” immunodeficiency).
Your breathing will be easier after an Ohio allergist has performed skin prick testing and/or blood testing to identify possible airborne allergens that trigger your rhinitis. Once these allergens are identified, you should avoid them if possible. Such measures may include remaining indoors when the pollen count is high and on windy days, dust-proofing the home and keeping animals out of the bedroom.
Treatment options may include the use of:
- Corticosteroid nasal sprays
Allergy shots, also known as allergen immunotherapy, may be recommended if avoidance and medications are not effective.
Allergic rhinitis can lead to recurrent or chronic sinusitis. The nasal obstruction and inflammation associated with allergic rhinitis interrupts the normal clearing of mucus from nasal passages, causing the sinus cavities to become clogged with mucus and making it difficult to breathe.
When you’re looking to breathe easy in Columbus, you’ve got to know what you’re up against in the area. Not all rhinitis can be blamed on Mother Nature. Rhinitis can result from anything, from the common cold, to cigarette smoke, cleaning solutions or chlorine in swimming pools. Rhinitis symptoms may also be caused by structural blockage of the nasal passage, irritants, medications, temperature changes and other physical factors. These are often called vasomotor rhinitis or non-allergic rhinitis.

Seasonal, which occur mainly during pollen seasons. Particularly bad Ohio allergens include Canadian goldenrod and carnations. Blooming trees, grass, and weeds also release pollen. With blooms occurring earlier and more pollen in the air, it is increasingly hard for allergy-sufferers to breathe easy in Ohio.
Perennial, which occur year round. Common allergens are mold, animal dander and dust mites.
Environmental allergies are generally known as allergic rhinitis. This is an allergic reaction that occurs in the nose when allergens in the air trigger the release of histamine. Histamine makes it difficult to breathe, causing inflammation, nasal congestion, swelling of the nasal membranes, blockage and reduction of normal sinus drainage.
There is no cure for food allergies, although many children do outgrow them. Here are some precautions Ohio allergists suggest you take:
- Avoid the food: The only treatment is complete avoidance of the specific foods that trigger the allergy.
- Ask about ingredients: People with food allergies must always inquire about ingredients when eating away from home.
- Read food labels: It is important to read food labels carefully. The United States has adopted food labeling rules that ensure that the common food allergens are listed in familiar language.
- Wear a medical alert bracelet: These inform health care workers and others of food allergies. They can be purchased in most drugstores or online.
- Be prepared for emergencies: Anaphylactic reactions caused by food allergies can be potentially life threatening. Fortunately, anaphylaxis can be treated with an injection of epinephrine, which can halt the progression of systemic symptoms and stop the reaction. Those with food allergies must carry and know how to use injectable epinephrine and antihistamines to treat reactions due to accidental ingestion.
A person is usually diagnosed with a food allergy after having a reaction that requires medical attention. If it is not clear what food caused the reaction, skin prick testing and/or ImmunoCAP blood testing may be performed by an allergist to identify the food allergen. Elimination diets, which involve removing certain foods from the patient’s diet, may also be implemented.
Eight foods account for up to 90% of all food-allergic reactions. They include:
- Tree nuts (such as almonds, cashews, walnuts, pecans, hazelnuts, Brazil nuts and pistachios)
Food allergies are on the rise. There is much ongoing research to learn more about the causes. The following factors make food allergies more likely:
- Family history: Many children with food allergies come from families with a history of food allergies, hay fever or asthma.
- Eczema: Many children who have food allergies also have eczema.
- Young age: Food allergies occur most often in infants and toddlers.
If you have a true food allergy, there is always a chance for anaphylaxis. Symptoms usually appear a few minutes to 1-2 hours after eating the food. The following are the most common symptoms of anaphylaxis, but each person may experience symptoms differently.
Food allergies develop when the immune system, for unknown reasons, fights against a particular food protein even though it is harmless. There are many people with food intolerances, which cause symptoms such as minor skin rashes or stomach upset. Food allergies, which trigger the immune system, are less common and more severe. True food allergy can cause anaphylaxis – a serious allergic reaction that is rapid in onset and may cause death.
Theses tests are performed at a hospital or radiology center where X-rays or CT scans are taken of the chest or sinuses in order to diagnose various lung diseases. Following the scan, a report will be sent to us and we may request that you bring a copy of the X-ray or CT scan to your appointment in order to go over the results. If it is determined you suffer from a lung condition, we will help determine the best course of action for treatment, which might include avoidance, allergen immunotherapy, and medication.
This test is typically administered for those who are unable to undergo a skin test due to antihistamine use, skin diseases, chronic hives, or an immune system disorder. By taking a sample of blood, this test can determine environmental allergies and food allergies, as well as immune system deficiencies. It can also evaluate those with chronic hives. Test results are not immediate and typically take a few days to a couple weeks to become available.
By breathing into a mouthpiece that is attached to a spirometer, the physicians are able to determine the the amount of air in your lungs and your ability to move the air out of your lungs. It is designed to diagnose issues with asthma and monitor any treatment methods. The test is non-invasive and the results are immediate. Upon taking the test, you might be given a bronchodilator treatment that will relieve some of the effects of asthma.
Patch Testing checks for chemicals that cause a delayed reaction, such as contact dermatitis. This test is performed by placing a safe, chemical patch on the person’s back. In order to have the patch placed on, patients should properly clean the skin and be freshly showered. No rubbing alcohol should be used in the cleaning process, and the patch will not be able to be properly placed if the subject is still wet. It the tape peels off, the entire process will have to be repeated. This patch stays on the skin for two days before being removed to be examined. It is again examined three to four days later to make sure nothing new has developed. The test is considered positive if blisters, bumps, or swelling develops. When you are preparing to have this test done, you should avoid taking any systemic immunosuppressants or oral steroids up to one month before, and topical steroids should not be used on the area of the skin that the patch will be placed one week before having the test done. Any use of inhaled steroids, leukotriene receptor antagonists, or antihistamines are still allowed to be used.
Our skin testing procedure checks for insect, food, and airborne allergens through the measurement of your allergic antibodies levels to these allergens. To do this we use a small plastic device that applies tiny amounts of solutions to the skin with a prick or scratch that contain the various types of allergens. By checking for an area of raised skin, we’ll be able to determine if there is a positive reaction. However, even if there is an area of raised skin, it does not necessarily mean you are allergic to an allergen, as other factors play a role in the test. If an allergen does not show up on a prick test, we will repeat the test using a tiny needle in which we will inject a small amount of that allergen into the first layer of skin, which will form a small, mosquito-like bite bubble. This test typically yields results in 15-20 minutes, and the area tested could get itchy, but not for very long. Prior to having this test administered, you should avoid using antihistamines 5 to 7 days before coming in to get tested. This skin test is not usually performed on those who have suffered a life-threatening reaction, or to someone who has hives or severe eczema.
Each patient may express their rhinitis differently, but symptoms and signs include:
- Struggling to breathe
- Runny nose
- Itchy nose, throat, eyes and ears
- Clear drainage from the nose
Children with perennial allergic rhinitis may suffer frequent ear infections, snore, breathe through the mouth, be frequently fatigued and, thereby, perform poorly in school.
