OBJECTIVE: Anaphylaxis is an acute, life-threatening systemic hypersensitivity reaction. We aimed to evaluate the demographic and clinical characteristics of patients presenting with anaphylaxis, as well as triggers and risk factors, and to determine the rate of adrenaline auto-injector (AAI) usage. METHODS: The study was planned in the pediatric allergy outpatient clinic over a 1-year period. The data of children diagnosed with anaphylaxis were evaluated retrospectively; demographic characteristics, causes of anaphylaxis, and treatment modalities were recorded in the created study form. RESULTS: Eighty children (29 females) with a median age of 6.5 years (range: 1 month-17 years) were evaluated. The most common triggers were foods under 2 years of age (73%), and drugs (70%) above 2 years of age. Nearly half of the anaphylaxis episodes (n=41, 51.3%) occurred at home. Cutaneous and respiratory symptoms were the most commonly reported complaints (98.8%). The median age of the patients at the first attack with severe anaphylaxis (n=29, 36.3%) was significantly higher than the rest (p:0.007). The age at onset of the reaction (p:0.006) and occurrence of the reaction in hospital conditions (p<0.001) were determined to be significant risk factors for severe anaphylaxis. Most of them received antihistamines (95.7%) and corticosteroids (91.3%), while 78.3% received adrenaline. Only 9.5% of patients with recurrent episodes of anaphylaxis used AAIs. CONCLUSION: Foods in infants and drugs in older children were the leading causative allergens of anaphylaxis. The most common clinical manifestations were respiratory and cutaneous symptoms. The older age at onset of the reaction and the occurrence of the reaction in hospital conditions were determined to be significant risk factors for severe anaphylaxis. It was determined that the frequency of AAI use was low among patients and their families.
