5 interesting cases of allergic cross-reactivity

5 interesting cases of allergic cross-reactivity


February 2, 2018

Allergy sufferers cope with their sensitivities in a number of ways, from over-the-counter medication and immunotherapy treatment to simple avoidance. Yet, even if a person was to employ every known method of avoidance, it’s still possible he or she would still experience an allergic reaction at a time when an allergen is nowhere to be seen.

The reason why is cross-reactivity, a phenomenon in which “the proteins in one substance are similar to the proteins found in another substance”. That means that a person allergic to a particular pollen may see a similar reaction after eating a nut, spice, or piece of fruit that is cross-reactive with that particular pollen.

When we consume a cross-reactive protein, the ensuing reaction is known as oral allergy syndrome, or pollen-food allergy syndrome. Oral allergy syndrome can be triggered by a variety of foods that many of us eat on a daily basis, resulting in mild to moderate symptoms that range from swelling and itching around the mouth to watery eyes and runny noses.

With that in mind, here are five cases of cross-reactivity to keep an eye out for the next time you’re at the grocery store.

1. Cypress pollen and peaches, citrus fruits

A recently discovered cross-reactivity according to Science Daily, peaches and citrus fruits such as oranges have demonstrated a possibility for allergic reactions. For people with cypress allergies, that is an issue not only when eating raw citrus fruits but when eating fruit-based products such as jams and marmalades.

2. Ragweed and melons, bananas, cantaloupe

Weeds are cross-reactive with a number of foods, and the association between ragweed and these sweet fruits is among the most common. Ragweed season typically occurs between late summer through fall, but ragweed allergy sufferers may find themselves facing similar symptoms after biting into a banana or slice of melon or cantaloupe.

3. Grass and watermelon, melons, tomatoes and oranges

Grasses like Timothy and Johnson can wreak havoc on allergy sufferers. So, too, can their cross-reactive cousins in the produce aisle of your local supermarket.

4. Birch and peanuts, hazelnuts

Many people suffer from common peanut allergies, while some may actually be allergic to birch tree pollen, which shares a similar protein to both peanuts and hazelnuts. According to PeanutAllergy.com, cooked and roasted nuts may also pose a threat, since their proteins are less sensitive to heat than others.

5. Mugwort and spices (anis, basil, chamomile, cilantro, dill, fennel, oregano, paprika, parsley, pepper, tarragon, thyme, and more)

Looking to spice up your life? It’s advised that you make sure you’re not allergic to mugwort, a weed that is cross-reactive with a number of spices you’ll find in your cupboard.

There are many other cross-reactive associations not listed here, which is why it’s important to understand both what your allergic sensitivities are, and what fruits, vegetables, nuts or spices they may be associated with.

Allergy awareness and avoidance are two positive steps you can take to combat allergies in your day-to-day life, but a better understanding of cross-reactivity is also important, helping ensure you know what to pick up – and what not to pick up – the next time you go grocery shopping.

May is Asthma and Allergy Awareness Month

May is Asthma and Allergy Awareness Month


May 2, 2017

The facts are staggering:

  • 1 in 5 Americans are affected by Asthma and Allergies1.
  • 1 in 10 children have asthma2.
  • Asthma and Allergy are the leading cause of missed school and work days3.

We are all familiar with the typical allergy symptoms; however, allergies can also manifest as fatigue, trouble focusing, depression, slowed thinking, ear infections, and dark circles/puffiness under the eyes.

Take the month of May to focus on potential Asthma and Allergy symptoms to improve the quality of life of your patients!

The recall is due to a potential defective part that would result in the devices’ failure to activate. Although there have been a small number of defective devices reported, Mylan is taking proactive actions to ensure the safety of their products.

The recalled products were distributed between Dec. 17, 2015 and July 1, 2016. Please check your epinephrine autoinjectors and compare with the Mylan Site for lot numbers and steps to return and replace your defective epinephrine autoinjector.

NEW PEER-REVIEWED ARTICLE DEMONSTRATES SAFETY OF SELF-ADMINISTERED ALLERGY SHOTS

NEW PEER-REVIEWED ARTICLE DEMONSTRATES SAFETY OF SELF-ADMINISTERED ALLERGY SHOTS


December 17, 2014

(Dec. 16, 2014) SAN ANTONIO – United Allergy Services (UAS) ®, a leading healthcare services company assisting family physicians and health systems to deliver safe and effective allergy testing and customized immunotherapy services, today announced the publication of an original article that analyzes the safety of implementing a self-administration protocol of allergen immunotherapy characterized by patient pre-selection and a slow buildup process. The peer-reviewed article written by Frederick M. Schaffer, M.D., a board certified allergist and lead investigator of the study, Andrew Naples and Larry Garner has been published online in the International Forum of Allergy & Rhinology.

The article, “The safety of self-administered allergen immunotherapy during the buildup and maintenance phases” concludes that the risk of systemic, or adverse, reaction is lower with UAS treatment protocol than traditional dosage and fast buildup, or RUSH, methods that involve immunotherapy shots administered at a physician’s office. The UAS protocol in the study was administered by primary care physicians and is characterized by self-administration at home. Investigators conclude that the results are driven by UAS patient pre-selection to exclude those with a high risk of adverse reactions and slower, more incremental, immunotherapy buildup phase as a self-administered treatment for patients suffering from seasonal and perennial allergies.

The article states, “The enhanced safety of this protocol results in a decreased frequency and severity of adverse reactions. This safety report corroborates and expands the observations of previous studies of self-administered, subcutaneous immunotherapy in a low-risk patient population by assessing self-administered allergen immunotherapy during the buildup and maintenance phases.”

Until recently, the only real relief for allergies and allergic asthma remained primarily in the hands of allergists who administer immunotherapy shots. This already small community of approximately 5,000 U.S. specialists is expected to decline 6.8 percent by 2020, while demand for allergy-related services is projected to grow 35 percent in the same timeframe. This forecast only scratches the surface of the true demand for allergy and asthma care, as only a portion of the approximately 60 million Americans suffering from allergic rhinitis are aware of their condition and seek specialty care.

About United Allergy Services
United Allergy Services ® (UAS) brings effective and convenient allergy testing and immunotherapy to primary care physicians, pulmonologists, ENT physicians, pediatricians, internal medicine physicians, and healthcare systems that treat the vast majority of patients with seasonal and perennial allergies. UAS’ complete service line features in-office UAS Certified Clinical Allergy Technician staffing and training; quality assurance and compliance; and supply and inventory management. By collaborating with physicians to safely administer allergy testing and shots, UAS has assisted the expansion of access to effective allergy care for thousands of patients that suffer from seasonal and perennial allergies.
