Retrospective evaluation of children with non-steroidal anti-inflammatory drug allergy

Aim: Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used drugs and are among the drug-related hypersensitivity reactions after antibiotics. There are limited studies evaluating nonsteroidal drug reactions in children. In this study, we aimed to evaluate the concomitant atopic diseases, admission clinic, laboratory findings and drug provocation test results of children with a pre-diagnosis of nonsteroidal drug reaction and who underwent allergy tests, retrospectively . Methods: In this study, patients who applied to the pediatric allergy outpatient clinic due to nonsteroidal drug reaction were included. In this group of patients, age, gender, fx5 (nutrient mix specific IgE), phadiatop (inhalant allergen mix specific IgE), skin prick tests and drug provocation tests were recorded from their files. Demographic and clinical features of the cases were compared. Results: 61 patients with suspected NSAIDs allergy were included in the study. When the admission clinics of the patients were evaluated, 54% (n:33) had urticaria, 22.9% (n:14) had isolated angioedema, 6.5% (n:4) had urticaria angioedema, 14.7% (n:9) had maculopapular eruption . Only 1 patient presented with anaphylaxis. NSAIDs allergy was confirmed in 16.3% (n:10) of the patients.. Single ibuprofen sensitivity was detected in 13.1% of patients (n:8), both paracetamol and ibuprofen sensitivity were detected in 1 patient (1.6%), and single paracetamol sensitivity was detected in 1 patient (1.6%). Conclusions: It is usually not easy to detect drug allergies in patients. These patients may usually misdiagnosed as NSAIDs allergy. In our study, it was revealed that drug provocation tests should be performed to confirm the diagnosis in case of suspected NSAIDs allergy.
