Abstract：Allergic reactions to peanuts in children have become a significant medical and legal concern worldwide, with a rising incidence of this potentially fatal condition. Peanut allergy represents an immunoglobulin E (IgE) mediated hypersensitivity reaction to peanut proteins. Exposure to the allergen was most commonly through ingestion, followed by presumed skin contact and inhalation. Clinical reactions frequently involve multiple organs including the cutaneous, cardiovascular, gastrointestinal, and respiratory systems. The ifrst step in identifying peanut as the cause of a reaction is a detailed history and physical examination. Detection of peanut-speciifc IgE by either skin prick test (SPT) or in vitro assays can help with diagnosis. Management of peanut allergy centers on educating patients and their families on complete avoidance of peanut-containing products, and have recognition of early signs of an allergic reaction, know the treatment of early stages of allergic symptoms, and follow-up long-term. New immunotherapeutic options are being investigated and appear promising.
