The U.S. Food and Drug Administration is alerting consumers to Meridian Medical Technologies’ voluntary recall of 13 lots of Mylan’s EpiPen and EpiPen Jr (epinephrine injection) Auto-Injector products used for emergency treatment of severe allergic reactions. This recall is due to the potential that these devices may contain a defective part that may result in the devices’ failure to activate. The recalled product was manufactured by Meridian Medical Technologies and distributed by Mylan Specialty. While the number of reported failures is small, EpiPen products that potentially contain a defective part are being recalled because of the potential for life-threatening risk if a severe allergic reaction goes untreated. Consumers should keep and use their current EpiPens if needed until they get a replacement. Consumers should contact Mylan at 800-796-9526 or email@example.com with any questions. As stated on the product label, consumers should always seek emergency medical help right away after using their EpiPens, particularly if the device did not activate. At this time, the 13 lots identified – distributed between Dec. 17, 2015, and July 1, 2016 – are the only EpiPen lots impacted by the U.S. recall. Consumers who have EpiPens from lots that are not included in this recall, do not need to replace their EpiPen prior to its expiration date.
The FDA asks health care professionals and consumers to report any adverse reactions or device malfunctions to the FDA’s MedWatch program, by:

“Sanofi and Regeneron Pharmaceuticals, Inc. announced today that the U.S. Food and Drug Administration (FDA) approved Dupixent® (dupilumab) Injection, the first and only biologic medicine approved for the treatment of adults with moderate-to-severe atopic dermatitis (AD) whose disease is not adequately controlled with topical prescription therapies, or when those therapies are not advisable.” After much anticipation, dupilumab becomes the first biologic approved for the treatment of atopic dermatitis (a form of eczema). Dupilumab is indicated for adults with moderate to severe eczema that are not well controlled with steroid creams or ointments. The current options for these patients are limited. Most often oral immunosuppressants, like prednisone or cyclosporine, are used. These medications may have several adverse effects. Dupilumab is a biologic that aims to more specifically target the underlying factors driving allergic inflammation. In this case it blocks the signals of two molecules, Il-4 and IL-13. Approval was based on three studies. The results of these studies showed the medication to be effective for the majority of patients. Additionally, 36-38% of patients achieved clear to almost clear skin. Dupilumab will come in a pre-filled syringe for self-administration, to be given by subcutaneous injection every other week. A loading dose in your physician’s office may be required. The wholesale cost was reported $37,000 per year. However, the actual cost to patients is still unknown. Future directions. Two studies are currently testing safety and effectiveness in children, 6 months to 11 years and 12 to 17 years of age. Other uses under investigation include asthma, nasal polyps and eosinophilic esophagitis. If you do have atopic dermatitis that is not well controlled, speak to your allergy doctor to see if dupilumab is right for you. To read more about dupilumab, click here. Also, to read about nemolizumab, a new and similar treatment option, click here.
Preventing allergy is a priority for both physicians and parents. There have been many studies attempting to lessen the risk of both food and environmental allergies. Here are a few examples of possible interventions to decrease the risk of allergy;
- Frequent application of emollients (moisturizers) from birth.
- Breast feeding, hypoallergenic formulas, early introduction of foods.
- Avoiding pets OR adding more pets.

Dog allergies are very common, up to 20% of the population are affected. This has not limited the popularity and enjoyment of having a dog at home. The ASPCA estimates that 37-47% of all households in the United States have a dog. Patients with dog allergies may have upper respiratory symptoms (sneezing, runny nose, itchy eyes), lower respiratory symptoms (cough, wheezing) or even skin symptoms (itching, rash). An allergist can confirm dog allergy as the cause of these symptoms. What’s next? What are the options? Removing the dog from the home is an option, but not very pleasing for the owners or their dogs. There are medications that can lessen symptoms. However, patients are looking for other ideas. Suggestions have included, frequent washing, frequent vacuuming, putting air filters in the house and buying a “hypoallergenic dog.” What is a “hypoallergenic dog?” The substance produced by a dog, causing an allergy is an allergen. The word hypoallergenic means less likely to cause allergy. This implies that the dog would produce less allergen. As of today, there have been six identified dog allergens, named Can f 1, 2, 3, 4, 5 and 6. These proteins are found in hair, skin, dander (skin flakes), saliva and urine. Each allergen can be found in each type, or breed of dog. Can f 1 and 5 are considered major allergens, causing allergy in a large percentage of patients. However, patients can be allergic to any single allergen or any combination as well. Interestingly, Can f 5 is found only in male dog urine, suggesting that some patients may be allergic to male dogs only. These proteins come off the dog and are found throughout the home. For example in carpets, couches and pillows. They can also be found in places without a dog. For example, in a classroom or on an airplane. A Google search will recommend, if you have allergies buy a hypoallergenic dog. Dogs that do not shed or with wiry hair. So is there such thing as a hypoallergenic dog? A dog breed that produces less allergen than other breeds? Is there anyone certifying or testing breeds to show that there are real benefits? Here are a few studies that may answer these questions: TITLE: Dog factor differences in Can f 1 allergen production. Allergy 2005. CONCLUSIONS:
- Allergen levels (Can f 1) were highest for Poodles (17) and Yorkshire Terriers (16) and lowest for the Labrador retriever (2).
- Males produced less allergen than females.
- There was no difference according to hair length or hormonal status.
- Skin seborrhea caused higher allergen levels.
- Choose a small dog. They will shed less dander.
- Keep the dog out of the bedroom and other rooms in which you spend a lot of time.
- Keep the dog out of the house. Remember, dogs may bring pollen or other allergens inside with them.
- Bathe your dog weekly.
- Remove carpet or other places dog dander may reside.
- Get a cat.
- MOST IMPORTANTLY: see an Allergist.
There is much interest in wheat sensitivity in people without celiac disease, many of these patients have been labeled with nonceliac wheat sensitivity. Little is known about any risks associated with nonceliac wheat sensitivity. A recent study published in the journal of Gastroenterology evaluated autoimmune diseases in patients with nonceliac wheat sensitivity and investigated whether they carry the autoimmune antibody (ANA). The study looked at patients who were given the diagnosis of nonceliac wheat sensitivity, celiac disease and control subjects. The ANA (autoimmune antibody) was measured in 3 groups. The authors concluded from the study that significantly higher proportions of patients with nonceliac wheat sensitivity or celiac disease have autoimmune disorders with positive ANA’s. This data provides physicians with an awareness that patients with nonceliac wheat sensitivity might have an increased risk of autoimmune diseases. Nonceliac wheat sensitivity remains a not well defined clinical condition. In fact there are some doubts about whether it is a real diagnosis. This study showed a higher frequency of autoimmune diseases, in particular thyroiditis, psoriasis and type 1 diabetes mellitus were reported. Allergists see many patients who are concerned regarding gluten allergy, many patients may in fact have nonceliac wheat sensitivity. This is relatively new diagnosis that there is not much information about. These are patients who do not have celiac disease or wheat allergy, but do have problems with eating gluten and/or wheat. Although allergy testing may be negative for these patients, this study shows that patients with nonceliac wheat sensitivity may have some autoimmune issues. There is still a lot to learn about nonceliac wheat sensitivity and as more studies come out we will learn more about it. Celiac disease has been in the news a lot recently http://allergylosangeles.com/allergy-blog/gluten-free-in-the-news/ As always speak to your doctor about any concerns that you have regarding gluten or wheat.
Generic Nasonex will soon be available for allergy sufferers. Apotex, is a generic pharmaceutical company, based in Florida, has successfully gotten FDA approval of the generic Nasonex (mometasone furoate). Generic Nasonex will still need a prescription. This is different than over the counter nasal steroid sprays that are available without a prescription from your doctor. There are currently 3 over the counter nasal steroid sprays available. Flonase, Nasocort and Rhinocort.

Consensus Communication on Early Peanut Introduction and the Prevention of Peanut Allergy in High-Risk Infants On behalf of American Academy of Asthma Allergy and Immunology, American Academy of Pediatrics, American College of Allergy, Asthma & Immunology, Australasian Society of Clinical Immunology and Allergy, Canadian Society of Allergy & Clinical Immunology, European Academy of Allergy and Clinical Immunology, the Israel Association of Allergy and Clinical Immunology, the Japanese Society for Allergology, Society for Pediatric Research, and the World Allergy Organization Introduction and Rationale Peanut allergy is an increasingly troubling global health problem, which affects between 1-3% of children in many westernized countries. Although multiple methods of measurement have been used and specific estimates differ, there appears to be a sudden increase in the number of cases in the past 10 – 15 year period, suggesting that the prevalence may have tripled in some countries, such as the USA. Extrapolating the currently estimated prevalence, this translates to nearly 100,000 new cases annually (in the USA and UK), affecting some 1 in 50 primary school-aged children in the USA, Canada, UK, and Australia. A similar rise in incidence is now being noted in developing countries such as Ghana.1-6 The purpose of this brief communication is to highlight emerging evidence to existing guidelines regarding potential benefits of supporting early, rather than delayed, peanut introduction during the period of complementary food introduction in infants. The recent study, entitled “Randomized Trial of Peanut Consumption in Infants at Risk for Peanut Allergy (Learning Early About Peanut – LEAP Trial),” demonstrated a successful 11% – 25% absolute reduction in the risk of developing peanut allergy in high-risk infants (and a relative risk reduction of up to 80%) if peanut was introduced between 4 and 11 months of age. In light of the significance of these findings, this document serves to better inform the decision-making process for healthcare providers regarding such potential benefits of early peanut introduction. More formal guidelines regarding early-life, complementary feeding practices and the risk of allergy development will follow in the next year from NIAID-sponsored Working Group and EAACI, and thus this document should be considered as interim guidance. Summary of New Evidence In the LEAP trial, 640 high-risk UK infants (See Textbox 1) between the ages of 4 to 11 months were randomized to consume peanut products at least three times a week (6 g of peanut protein; equivalent to 24 peanuts or 6 teaspoons of peanut butter per week) or to completely avoid peanut products for the first five years of life. This included 542 infants found to have negative skin prick tests (SPT) to peanut at study entry, and 98 infants with SPT wheal diameters to peanut between 1 to 4 mm (minimally SPT positive) at study entry. An additional 76 children were excluded from study entry prior to randomization based on SPT > 5mm, which was assumed to have a very high likelihood of reacting to a peanut challenge. In an Intention-To-Treat (ITT) analysis, 17.2% in the peanut avoidance group compared to 3.2% in the peanut consumption group developed food challenge-proven peanut allergy by age 5 years, corresponding to a 14% absolute risk reduction, a number needed to treat (NNT, e.g. number of persons needed to be treated for one to receive benefit) of 7.1, and a relative risk reduction of 80%.7 When examined in further detail, the isolated beneficial effects for both the primary and secondary prevention of peanut allergy translated to a NNT = 8.5 within the SPT negative and NNT = 4 within the minimally SPT positive infants. Secondary analyses also showed similar levels of prevention in White, Black and Asian (Indian and Pakistani) children. Overall, the risk of early introduction in this group was low– 7 of the 319 children randomized to the consumption group reacted to peanut at the baseline food challenge suggesting that peanut food challenges and introduction, even in minimally SPT positive infants, is safe and feasible. Six children in the consumption group developed peanut allergy during the study indicating that peanut allergy can still develop despite attempts at primary and secondary prevention. Finally, the LEAP trial only included high-risk infants with a minimal or negative SPT to peanut, and therefore does not address a strategy for those without these risk factors for developing peanut allergy.7 How Does The LEAP Trial Affect Present Guidance for Early Complementary Feeding Practices? Existing guidelines pertaining to the early introduction of complementary foods have indicated that the introduction of highly allergenic foods, such as peanut, need not be delayed past 4 or 6 months of life. However, they do not actively recommend introduction of peanut between 4 – 6 months of age in high-risk infants, and some of these guidelines specify that those infants considered at risk for the development of allergic disease are strongly recommended to first consult an expert.8-14 The LEAP data provide Level 1 evidence that the practice of early peanut introduction is safe and effective in selected high-risk infants. This study is the first prospective, randomized trial of early peanut intervention, and informs provider decision-making regarding high-risk infants, including those already with a positive peanut SPT but not yet clinically reactive, to receive the benefits noted in the LEAP study, which may reduce the risk of developing peanut allergy up to 80%. Of note, since children with lesser risk factors for peanut allergy were excluded from enrollment in LEAP, there are no prospective, randomized data investigating the benefit or risk of early peanut introduction in the general to low-risk populations. However, multiple guidelines have not recommended delaying allergen introduction in these populations. On this basis, this communication is limited to helping integrate the findings learned in the LEAP trial to other similar high-risk children in more diverse settings internationally. Interim Guidance Regarding Early Peanut Introduction Based on data generated in the LEAP trial and existing guidelines, the following interim guidance is suggested to assist the clinical decision-making of healthcare providers: There is now scientific evidence (Level 1 evidence from a randomized controlled trial) that healthcare providers should recommend introducing peanut-containing products into the diet of “high-risk” infants early on in life (between 4 – 11 months of age) in countries where peanut allergy is prevalent, since delaying the introduction of peanut may be associated with an increased risk of developing peanut allergy. Infants with early-onset atopic disease, such as severe eczema, or egg allergy in the first 4-6 months of life (see Text Box 1 for example LEAP criteria), may benefit from evaluation by an allergist or physician trained in management of allergic diseases in this age group to diagnose any food allergy and assist in implementing these suggestions regarding the appropriateness of early peanut introduction. Evaluation of such patients may consist of performing peanut skin testing and/or in- office observed peanut ingestion, as deemed appropriate following discussion with the family. The clinician may perform an observed peanut challenge for those with evidence of a positive peanut skin test to determine if they are clinically reactive before initiating at-home peanut introduction. Both such strategies were used in the LEAP study protocol. Adherence in the LEAP trial was excellent (92%) with infants randomized to consume peanut ingesting a median of 7.7 g peanut protein (interquartile range: 6.7 – 8.8 g)/week during the first 2 years of the trial compared to a median of 0 g in the avoidance group (see Text Box 2 for examples of peanut-containing foods utilized in the LEAP trial). While the outcome of the LEAP regimen was excellent, the study does not address use of alternative doses of peanut protein, minimal length of treatment necessary to induce the tolerogenic effect, or potential risks of premature discontinuation or sporadic feeding of peanut. Rationale for evaluating and applying this policy to a high-risk population The LEAP study demonstrates that early peanut introduction can be successfully carried-out in a high-risk population (such as the population defined in the LEAP trial). However, without intervention by healthcare providers, there is the potential that such high-risk infants will remain at risk for delayed introduction of solids and allergenic foods into their diet because of the widespread belief that such foods may exacerbate eczema. Future more extensive guidelines will be forthcoming from the NIAID Working Group and EAACI Guidelines Group with their multidisciplinary stakeholders. These groups will consider all the available data and determine whether there is sufficient evidence to apply prevention strategies to the general population. However, engagement of the primary care, allergy and dermatology communities to rapidly implement these findings and change the culture of early feeding practices is essential, and the forthcoming NIAID Working Group’s and EAACI Guidelines Group’s documents will better clarify a best-practices approach.

(Accessed April 2, 2015) Text Box 1: Enrollment Criteria Used in the LEAP Study Infants considered at “high risk” as defined by the LEAP study criteria: Egg allergy: Children with either – 1) a SPT wheal diameter ≥6 mm from exposure to raw hen’s egg white and no history of previous egg tolerance, or 2) a SPT wheal diameter ≥3 mm from exposure to pasteurized hen’s egg white and allergic symptoms related to exposure to hen’s egg. Severe eczema: An eczematous rash that – 1) requires the application of topical creams and/or ointments containing corticosteroids or calcineurin inhibitors, and if the participant is <6 months of age, lasted for at least 12 out of 30 days on two occasions, or if >6 months of age, lasted for at least 12 out of 30 days on two occasions in the last 6 months, or 2) is currently or was previously graded ≥ 40 using the modified SCORAD evaluation Example of method of skin prick testing: used in the LEAP study • Skin prick test to peanut extract done in the presence of a negative control and a positive histamine control. • Skin prick testing should be performed in duplicate and the maximum wheal diameter of the two skin prick tests should be calculated and rounded up to the greatest whole millimeter Of note, in the LEAP trial, the use of IgE measurement to peanut resulted in considerably higher rates of sensitization compared to skin testing, which could lead to numerous unnecessary oral peanut challenges. Text Box 2: Examples of Peanut-containing Foods Utilized in the LEAP Trial Smooth peanut butter (2 teaspoons) mixed with milk or with mashed or pureed fruit *Bamba® snack (Osem; ~2/3’s of 1 oz. (25 g) bag; 21 sticks of Bamba®) – for young infants (<7 months), softened with 20 – 30 ml water or milk and mixed with milk or with mashed or pureed fruit or vegetables Peanut soup Finely ground peanuts mixed into other foods such as yoghurt (*Other foods more customary to particular nations/cultures may be substituted) Whole peanut is not recommended for introduction as this is a choking hazard in children under the age of 4.
