Are tree nut allergies diagnosed too often?


Study finds 50 percent of those who think they’re allergic pass an oral food challenge.Many patients with a history of a single tree nut allergy are told to avoid all other tree nuts.  But is that necessary? If you have a tree nut allergy and were advised to avoid other tree nuts based only on a positive blood or skin prick test, you may not be allergic to the other nuts. New research strongly suggests you should consider having an oral food challenge to properly diagnose additional nut allergies, especially if you’ve never had a reaction to eating those tree nuts before.A new study in Annals of Allergy, Asthma and Immunology, the scientific publication of the American College of Allergy, Asthma and Immunology (ACAAI) showed that among people allergic to one nut who have a positive test to other tree nuts, more than half passed an oral food challenge to other tree nuts without a reaction. Passing an oral food challenge means you aren’t allergic to that nut. Tree nuts include almonds, cashews, walnuts and hazelnuts, but not peanuts. The study noted that nearly none of the people allergic to peanut, but sensitized to tree nut, were clinically allergic to tree nut. This is the first study indicating that peanut allergic people may not need to avoid all nuts.“Too often, people are told they’re allergic to tree nuts based on a blood or skin prick test,” says allergist Christopher Couch, MD, ACAAI member and lead author of the study. “They take the results at face value and stop eating all tree nuts when they might not actually be allergic. We examined records of 109 people with a known tree nut allergy to an individual nut. They were tested for other tree nuts they had never eaten before using blood or skin prick tests. Despite showing a sensitivity to the additional tree nuts, more than 50 percent of those tested had no reaction in an oral food challenge.”  An oral food challenge is considered the most accurate way to diagnose food allergy. During an oral food challenge, the patient eats tiny amounts of the food in increasing doses over a period of time, followed by a few hours of observation to see if they have a reaction. An oral food challenge should only be conducted under the care of a trained, board-certified allergist. You should never do one on your own since if you are allergic, you could have a severe, life-threatening reaction.“Previous studies suggested people with a tree nut allergy, as well as those with a peanut allergy, were at risk of being allergic to multiple tree nuts,” said allergist Matthew Greenhawt, MD, chair of the ACAAI Food Allergy Committee and study co-author. “We found even a large-sized skin test or elevated blood allergy test is not enough by itself to accurately diagnose a tree nut allergy if the person has never eaten that nut. Tree nut allergy should only be diagnosed if there is both a positive test and a history of developing symptoms after eating that tree nut.”Dr. Greenhawt stressed the study did not include challenges to nuts that the individual had a documented history of having a reaction to when eaten.  “The practice of avoiding all peanut and tree nuts because of a single-nut allergy may not be necessary,” says Dr. Greenhawt. “After an oral food challenge, people allergic to a single tree nut may be able to include other nuts in their diet."

Advances in Allergen Immunotherapy at NYM

Dr Charlot cropped

To call allergen immunotherapy time-tested is an understatement. Commonly known as "allergy shots," the introduction of allergen immunotherapy predates Prohibition, and has been an effective treatment for patients living with severe allergies since Herbert Hoover sat in the White House.

Almost a century later, there is an ever-expanding array of effective, once-a-day medication available to treat allergy symptoms. But immunotherapy remains the only treatment that can alter the natural course of an allergic Cascya Charlot, M.D., was recently appointed director of NYM's Division of Pediatric Allergy and Immunology. disease like chronic rhinitis (hay fever) or allergic asthma, and permanently reduce the frequency and severity of allergy symptoms such as severe congestion, sinus pressure, grogginess and sleeplessness. Furthermore, ongoing research and refinement of immunotherapy guidelines have made immunotherapy treatments for outdoor and indoor allergies more effective than ever before. Perhaps this is why, more and more, Brooklynites are requesting allergen immunotherapy for their children, says Cascya Charlot, M.D., who was recently appointed director of NYM's Division of Pediatric Allergy and Immunology.

"Children can start immunotherapy as early as age five, and many children living in Brooklyn are just reaching that age," says Dr. Charlot. "A full course of allergen immunotherapy takes time—usually three to five years, starting with weekly visits for injections for the first six months, and then monthly visits for the remainder. However the benefits of immunotherapy can last a lifetime, particularly for children living in New York City, where pollen, mold spores and dust mites can be found around every corner. In addition, the first FDA-approved oral, injection-free immunotherapy (specifically, for grass pollen allergies) became available in 2014. More are sure to come."

For those with milder allergy symptoms that occur seasonally, over-the-counter treatments and lifestyle adjustments may be all that is necessary. Dr. Charlot is quick to point out that a common problem is that many of these patients do not even know that their springtime cold or upper respiratory infections have, in fact, been caused by a seasonal allergy.

"A simple 'scratch test,' performed by an immunologist, would likely have been able to identify that allergy in less than 30 minutes, and get the patient on the road to effective relief of symptoms," says Dr. Charlot. "What matters most is getting started, and finding the right treatment for each individual patient. Many parents of my patients tell me that they wish they had known about allergen immunotherapy when they were growing up, or that they had found out that they were allergic to pollen when they were younger. I tell them that there is no time like the present!"
