Anaphylaxis is a potentially life-threatening condition. There are limited data about the etiology and the clinical characteristics in developing countries. This study aimed to investigate the clinical characteristics of anaphylaxis patients attending our pediatric allergy clinic. We conducted a prospective analysis of patients who were admitted to our allergy clinic for anaphylaxis from 2010 to 2012. Ninety-six patients were evaluated during the study period. The mean age was 7.4 ± 5.2 years. Venom, food, and drugs were the most common causative agents responsible for 31 (32.3%), 30 (31.3%), and 26 (27.1%) of the cases, respectively. Foods implicated most frequently were peanuts and nuts (n = 9; 30.0%), cow's milk (n = 7; 23.3%), and egg white (n = 6; 20.0%). The clinical manifestations during anaphylaxis in order of frequency were cutaneous (97.9%), respiratory (86.5%), gastrointestinal (42.7%), neurological (37.5%), and cardiovascular symptoms (30.2%). A biphasic course was noticed in five cases (5.2%). Of the 91 patients, 79 (86.8%) received H1-antihistamines, 73 (80.2%) received corticosteroids, 40 (44.4%) received adrenaline, 38 (41.8%) received fluid replacement therapy, 18 (19.8%) received β2-mimetics, and 8 (8.8%) received H2-antihistamines. According to severity, 7.3% of patients had mild, 59.4% had moderate, and 33.3% had severe anaphylaxis. Food and bee venom allergy were the most common etiologies. Adrenaline, the first-line treatment of anaphylaxis, was administered in only 44.4% of our cases.
