Abstract
Background

Drug hypersensitivity reactions (DHR) are common in the paediatric population, representing a public health problem. Recent studies have confirmed that the frequency of drug allergy is overestimated by both parents and physicians. The aim of this study is to determine the prevalence and risk factors of actual drug allergies in children admitted to a tertiary referral allergy centre.

Methods

Medical records covering the period of 2005–2010 of children with a history of DHR were reviewed. Demographic features of the patients and results of skin and drug provocation tests were noted. The European Network for Drug Allergy (ENDA) questionnaire was filled by using medical records and making phone calls with parents.

Results

Ninety-six patients with 140 DHRs were evaluated. Seventeen children had confirmed drug allergy by positive skin tests (n=11) and drug provocation tests (n=5). One patient underwent severe anaphylaxis and subsequent cardiac arrest during infusion of the drug, and therefore diagnostic tests were not performed. Actual drug allergy was more frequent in children with chronic diseases (58.8% vs. 26.5%, p=0.018) and histories of anaphylaxis during DHR (58.8% vs. 24%, p=0.001). The patients’ history of anaphylaxis [OR: 5.789, 95%CI: 1.880–17.554, p=0.002], sweating [OR: 7.8, 95%CI: 1.041–58.443, p=0.046] and dyspnoea [OR: 5.230, 95%CI: 1.836–14.894, p=0.002] during suspicious DHRs increased the risk for actual drug allergy.

Conclusion

Actual drug allergy was determined in 17.7% of the patients with a suspicious DHR. Having a history of anaphylaxis during suspected drug reactions as well as symptoms of sweating and dyspnoea increased the risk for actual drug allergy.
