INTRODUCTION: Ibuprofen is the most common culprit drug causing nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity in children. We aimed to evaluate the frequency, clinical characteristics, and risk factors of confirmed ibuprofen allergy in children presenting with a history of suspected immediate type ibuprofen-induced hypersensitivity reactions.
METHODS: We evaluated 50 (35 M, 15 F) children with a median age of 7 years, who were referred to our clinic with suspected immediate ibuprofen hypersensitivity. Patients were subjected to a diagnostic work up including drug provocation tests (DPTs) with the culprit drug. Reactions were classified according to the European Academy of Allergy and Clinical Immunology Task Force recommendations for pediatric patients. Proven ibuprofen allergic patients underwent DPT to find a safe alternative drug.
RESULTS: Ibuprofen allergy was confirmed in 34% (n: 17) of children; 9 patients were diagnosed by DPTs and 8 patients diagnosed based on their histories. Angioedema was the most common clinical manifestation (n: 30, 60%). Among patients with proven ibuprofen allergy, 7 of them were classified as cross-intolerant. Cross-intolerance reactions were further classified as NSAID-exacerbated cutaneous disease (n = 1) and NSAID-induced urticaria/angioedema/anaphylaxis (n = 6). As an alternative drug, paracetamol was safely tolerated, whereas 1 patient developed angioedema and urticaria with nimesulide. Older age and male gender were identified as independent risk factors for immediate-type ibuprofen allergy.
CONCLUSION: DPTs should be performed to confirm or exclude ibuprofen allergy in children and to find safe alternative drugs. Male gender and older age are risk factors for ibuprofen allergy. NSAID-induced hypersensitivity reactions in the pediatric population cannot be well defined using the adult classification system.
