Allergocomponent diagnostics in the management of comorbid patients

Polyvalent sensitization (simultaneous formation of antibodies to allergens from several sources, for example, to cat allergens, birch pollen, strawberry allergens), which can occur at any age, concerns a significant number of patients with allergic diseases. The diagnostic search for a causal allergen is difficult in patients with polyvalent sensitization and/or cross-reactions to allergens of unrelated groups of allergens. We have carried out work on the detection of polysensitization in patients by the ALEX2 molecular diagnostic method, which detects specific antibodies to 300 allergens (120 allergens and 180 allergenic molecules + total IgE) in one study. The presented clinical examples clearly show the possibility of identifying the spectrum of causal allergens to clarify the diagnosis, which subsequently makes it possible to prescribe the right treatment to prevent the development of complications, which is especially important for comorbid patients
