Multiple Allergen Simultaneous Test for Food Allergens Cannot Screen Wheat-Dependent, Exercise-Induced Anaphylaxis and α-Gal Syndrome.

Park JS, Yoo Y, Kwon JW

Screening tests for specific immunoglobulin E (sIgE) to food allergens, such as the multiple allergen simultaneous test (MAST), are widely used in patients with suspected food allergies in South Korea. We evaluated whether MAST could effectively screen wheat-dependent exercise-induced anaphylaxis (WDEIA) and α-gal syndrome (AGS). We retrospectively reviewed patients with WDEIA and AGS diagnosed with unequivocal history and positive sIgE results for omega-5 gliadin and α-gal using ImmunoCAP, respectively. The clinical manifestations and results of MAST and ImmunoCAP (sIgE to wheat for WDEIA and beef/pork for AGS) were reviewed. In the MAST and ImmunoCAP results, class 0 (<0.35 units in each test) was considered negative. Medical records of 45 patients with WDEIA and 39 patients with AGS were reviewed. For WDEIA, 37 (82.2%) of patients had a history of anaphylaxis. Among those positive for omega-5 gliadin sIgE, 39 (87.7%) and 25 (55.6%) tested positive for gluten- and wheat-sIgE using ImmunoCAP, respectively. MAST performed on 15 patients yielded positive results for wheat-sIgE in 5 (33.3%). For AGS, 23 (59.0%) of patients had a history of anaphylaxis. Among those positive for α-gal sIgE, 32 (85.7%) and 37 (96.4%) tested positive for pork- and beef-sIgE using ImmunoCAP, respectively, whereas MAST could not detect sIgE for pork and beef (0%, 0/17). MAST for sIgE to food allergens cannot screen WDEIA and AGS. The tests for sIgE to a specific component of food allergen, such as omega-5 gliadin for WDEIA and α-gal for AGS, should be used to screen WDEIA and AGS.

Extrinsic and Intrinsic Modulators of Anaphylaxis.

The journal of allergy and clinical immunology. In practice •

The severity of anaphylaxis is determined by many factors. The allergenic source as well as the age of the affected individual and the route of allergen exposure encompass the major contributors of the clinical outcome. Moreover, the severity can be modulated further by intrinsic and extrinsic factors. Among these, the genetic predisposition, certain comorbidities such as uncontrolled asthma, and hormonal fluctuations have been proposed as intrinsic and antihypertensive medications or physical activity as extrinsic factors. Recent advances have highlighted immunologic pathways that may exacerbate the response to allergens through receptors on mast cells, basophils, platelets, and other granulocytes. Atopy, platelet-activating factor acetylhydrolase deficiency, hereditary alpha tryptasemia, and clonal mast cell disorders are examples associated with genetic alterations that may predispose to severe anaphylaxis. Identifying risk factors that lower the threshold of reactivity or increase the severity of multisystem reactions is important in the management of this patient population.
