What this Trial Is About
Researchers are studying patients who have experienced anaphylactic reactions due to food allergies, focusing on allergies to legumes, tree nuts, seeds, cereals, or pseudocereals. The study aims to understand how often repeat anaphylactic reactions occur with different food triggers after patients have been identified and counseled on avoiding these allergens. This observational study seeks to improve care by learning about patterns in allergic reactions and patient management over time. Participants are asked to complete electronic questionnaires at the start and then at 3, 6, 12, and 24 months after joining the study. These questionnaires collect information about new allergic reactions, eating habits, quality of life related to food allergies, and use of emergency medication. The study tracks whether repeat reactions occur to known or new allergens and examines reaction symptoms and management strategies. During the study, participants will regularly report their experiences via online surveys sent by email. Researchers will analyze the frequency of allergic reactions, quality of life impacts, dietary behaviors, and emergency medication use over the two-year period. The main outcome is how often allergic reactions happen in patients with tree nut and peanut allergies. The study is designed to better understand self-management and improve future care for food allergy patients.
