Preventing Peanut Allergy with Early Exposure

Peanut allergy can result in severe, and at times fatal, allergic reactions. Unfortunately, peanut allergy has become more and more common over the years. A new study, however, gives hope that early interventions may decrease the risk of developing peanut allergy.

A recent study published in the New England Journal of Medicine suggests that early exposure to peanuts helps to prevent peanut sensitization in high risk children.  The study was performed in response to the significant increase in the incidence of peanut allergy worldwide, especially in westernized countries, such as the United States.  The most recent recommendations by the American Academy of Pediatrics (AAP) came in 2000, in response to outcomes from infant feeding trials conducted in Europe and the United States.  At that time, the AAP recommended refraining from introduction of peanuts to children until age 3.  Despite this recommendation, the incidence of peanut allergy continues to rise, and in 2008, the AAP retracted its recommendation due to insufficient evidence.  Since that time, multiple observational studies have found that early introduction of peanut protein, as well as cow's milk and egg, result in decreased incidence of these food allergies.  
 
In a new study by Du Toit et al., Learning Early about Peanut Allergy (LEAP), investigators studied over 500 infants at high risk of peanut allergy (severe eczema, egg allergy, or both).  Half of the children were randomly selected to consume peanuts and the other half, to avoid peanuts.  At age 5, the children underwent peanut challenge to determine if they were allergic.  Results indicated that the prevalence of peanut allergy in the peanut-avoidance group was significantly higher at 17.2%, compared to 3.2% in the group that consumed peanuts.
 
The trial went on to compare two groups: one group of infants with skin prick test (SPT) that was initially negative to peanut, and another with mildly positive results (wheal of 1-4mm).  Infants with a wheal of >4mm were excluded from the study (about 10%).  In infants with an initially negative SPT, prevalence of peanut allergy was 13.7% in the avoidance group and 1.9% in the consumption group.  For infants with mildly positive SPT, the prevalence of peanut allergy was 35.3% in the avoidance group and 10.6% in the consumption group.  
 
Although many questions still remain, early testing of infants at high risk for peanut allergy in the first 4-8 months of life, along with early introduction of peanut protein or in-office peanut challenge may have the potential to prevent peanut allergy in the future.

The Importance of Using Controller Medicines Daily

Asthma is a condition due to airway inflammation often associated with an allergic component. It is characterized by symptoms that can include chest tightness, cough, shortness of breath and wheezing, which may be intermittent or persistent. Proper diagnosis requires a thorough history, physical examination, appropriate lung function testing and allergy testing.

 
Acute, or severe asthma, can present as a rapid or gradual increase in symptoms resulting in an acute attack or exacerbation. Chronic asthma, or persistent asthma, may present with intermittent symptoms or even nocturnal awakening.
 
Control of asthma is defined as an absence or decrease in asthmatic symptoms and improvement in the quality of life. A 5-question survey known as the ACT defines uncontrolled asthma on the basis of a score of less than 19 out of a possible 25.
 
The key to controlling asthma is through the regular use of asthma controller medications such as inhaled corticosteroids, antileukotrienes, or combination inhalers containing inhaled corticosteroids and long-acting bronchodilators. These drugs treat the underlying cause of asthma, namely airway inflammation. They are most often delivered by inhalers with the exception of the antileukotrienes, which are taken orally. Short-acting bronchodilators such as albuterol, are considered relievers and are meant to be used on an as-needed basis or before exercise.  The need for a reliever inhaler more than 2 days a week or 2 nights a month is a sign of poorly controlled asthma.
 
Recent studies have demonstrated adherence to asthma medications averages only 50%. In other words, one-half of patients do not take their controller medicine regularly. This is extremely important, as improved adherence is associated with less asthma attacks and an improved quality of life and more symptom-free days. Thus non-adherence is associated with a lack of asthma control, poor health outcomes and increased costs.
 
The reasons for the lack of regular use of asthma control drugs are varied. The cost, co-pays and coverage for these drugs varies widely and high costs can be a barrier for many people. Some patients are worried about ‘being dependent’ on daily medications while many people simply find it hard to remember to take medication once or twice a day. Additionally, correct inhaler technique is vital to ensure that the medicine, when taken, is effective.
 
The physician-patient relationship is vital in improving adherence. Understanding, trust and mutual respect are absolutely necessary between a patient and physician. For example, patients should understand the difference between an oral steroid like prednisone  and an inhaled corticosteroid in terms of their safety and efficacy. Patients should feel confident in why they are taking certain medications and in how they are taking it. Regular follow up visits are vital. Asthma can have fluctuations that require adjusting therapy up or down depending on the situation. Thus prescribing or changing an asthma regime requires feedback to insure safety, efficacy and compliance. Adjustments in dosing, if needed,  can be made on subsequent visits, usually 4-6 weeks apart, or as long as 90 days.
 
Newly developed electronic monitoring devices have the potential to be a very important asset to remind and reinforce with patients when to take their medication. Such devices may even provide vocal reminders that the medicines are due. Documenting the regular use of these medications is of great use to physicians as well as to patients.
 
In addition to devices that remind us to take medication, the future of asthma therapy will no doubt include lung function peak flow monitoring via the smart phone. This will allow both patients and physicians to get a much fuller picture of an individual’s asthma and allow far greater individualized care.
 
Managing asthma successfully hinges upon using controller medications, such as inhaled steroid, regularly. Regular use improves symptoms and quality of life and reduces the risk of asthma exacerbations. For many, however, adherence can be challenging. Effecting behavior change is quite difficult and time consuming. It requires reinforcement and even such devices as peak expiratory flow meters to be used by the patient at home. Technology should lead the way in helping patients and physicians alike improve asthma control.  In recent years we have all seen tremendous advances in technology that have not only made our lives better, but improved the quality of our lives. Such an outcome would be welcome in the care of our asthmatic patients. As Leaders in Allergy and Asthma Care, Allergy Partners is actively working to bring this technology to our patients.

Outdoor Air Quality: How to Protect Yourself from Unhealthy Air

Have you ever wondered what to make of those air quality warnings you hear on the news?  These warnings are intended to help you take action to avoid harmful air, but it is not always clear what they really mean and what actions are reasonable and necessary.  Here is a brief history of the system behind the Air Quality Index (AQI), and education regarding how these warnings can help you breathe better.

 
The AQI was developed by the Environmental Protection Agency in 1968.  It measures the levels of 5 major air pollutants regulated by the Clean Air Act: particle pollution, ground-level ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide.   Of these, ozone and particle pollution pose the greatest risk to your health. 
 
The AQI is a number from 0-500 for each of these pollutants, and anything below 50 is considered good.  From 50-100 only very sensitive people will be affected.  Above 100 more people will begin to experience problems, especially people with allergies, asthma, COPD, heart disease, the elderly, and children.  Above 150 even healthy people might begin to have problems.
 
 
 
Health effects of air pollution include irritation of the nose, throat, and lungs, worsening asthma, increased susceptibility to respiratory infections, and even long term damage to these areas if the exposure is high and prolonged.
 
So what action should you take when the AQI is elevated?  The first step is to build awareness of how your own body reacts to air pollution, by keeping track of air quality (
 
www.airnow.gov or the AIRNow app), and seeing what symptoms you experience.  You may find you need to take precautions in the Yellow or Orange range.  Everybody should take precautions once levels are in the Red range or worse.  Precautions include avoiding exercising outdoors when AQI is poor, and limiting your children’s outdoor play.  Go to the gym or walk at the mall instead of jogging outdoors.  Use the air conditioner in your home and auto to help filter the air.  If you have asthma or allergies you may need to take extra precautions.  Discuss this with your Allergy Partners physician and make a plan to maintain optimal health.

Alternative Medicine and Allergy/Asthma: What Really Works

Pharmacy shelves are stocked with herbs and supplements that claim to improve health. Such complementary and alternative medicines (CAM) are part of a group of diverse medical and healthcare systems, practices, and products that are not generally considered part of the conventional medical practices.

Over 42 percent of people in the US (both adults and children) have used CAM for their allergic disorders. Such treatments are perceived to be natural and safe by patients, but reporting of adverse effects is largely inadequate. But do CAM therapies really help with allergies and asthma? Importantly, are CAM therapies safe?

Chinese Herbal Medicine has been used for centuries in Asia. However, lack of standardization and controlled clinical trials have hampered their use as conventional therapies in Western medicine. There is potential for developing novel therapies for atopic diseases from Chinese herbs. Several herbal formulas show early promise for the treatment of asthma, food allergies, and allergic rhinitis in randomized trials. Work remains to determine the active components of each herb and their mechanisms of action. In addition, issues with consistency of herb quality and standardization still need to be addressed.

Other Herbal therapies like Ayurvedic mixes, butterbur, and Tinofend have demonstrated some efficacy but these treatments may have side effects.  These products are not systematically monitored for safety by drug regulatory bodies. Herbal remedies, including teas, made from plants can cause allergic reactions, such as hives, or can induce asthma symptoms. Pregnant and nursing patients should be advised to avoid these herbal therapies.

Nasal sprays consisting of dilute solutions of capsaicin or inert, micronized cellulose powder have shown efficacy for allergic rhinitis. Nasal saline lavage, commonly with a nettie pot can be effective in alleviating symptoms of nasal congestion and drainage.

A variety of other herbal preparations, homeopathic products, and miscellaneous therapies have been suggested for the treatment of allergic rhinitis or conjunctivitis. However, studies have either been of low quality or failed to show benefit.  Additionally, a number of herbs such as chamomile and Echinacea can cause allergic reactions in people who are allergic to ragweed pollen.

Vitamin D deficiency has been increasingly recognized as a health issue, particularly in northern latitudes. Low Vitamin D levels have been associated with increased rates of food allergy. It’s too early to say whether vitamin D can reverse food allergies. Future research is needed to answer that question. However, research is beginning to support the idea that vitamin D can protect against food allergies and vitamin D is important for overall good health.
For most people, the best way to ensure you have enough vitamin D is a combination between sensible sun exposure and adequate intake of foods containing the vitamin. Your doctor can assess your vitamin D status with a simple blood test and recommend a supplement if necessary

Non-pharmacologic interventions such as Acupuncture and Acupressure (Stainless steel pellets in adhesive discs are applied to specified points “acupoints” on the ear) show modest benefit in the treatment of allergic rhinitis, although it is difficult to estimate the size of the effect in most studies. 

With all CAM interventions, it is vitally important to discuss your use of these therapies with your doctor. Additionally, CAM therapies should not be used in place of conventional therapies without first talking to your doctor.
