Abstract
Introduction: Beta-lactam antibiotics (BLAs) are the most common cause of drug hypersensitivity reactions in children, and it is important to find safe alternative antibiotics for these children. This study evaluates the selection, safety to alternative antibiotics in patients with confirmed BLA allergies based on diagnostic tests.
Methods: At the Pediatric Immunology and Allergy Clinic of Ankara Bilkent City Hospital, a retrospective evaluation of diagnostic tests (including skin prick, intradermal, and drug provocation tests) was conducted to identify alternative antibiotics for patients with confirmed BLA. Patients were also contacted by telephone to assess their use of these alternative drugs.
Results: The study included 80 patients with confirmed beta-lactam allergy (BLA). The BLAs causing reactions were categorized into two groups: penicillins (75%, n = 60) and cephalosporins (25%, n = 20). Among the penicillins, amoxicillin-clavulanic acid (ACA) was the most common at 68.8%, while among the cephalosporins, ceftriaxone was the most common at 16.3%. Of the 55 patients with ACA allergy, 53 underwent controlled administration with clarithromycin, with 52 showing no reaction. In addition, no reaction was observed in patients who received DPT with cefuroxime (n: 16), phenoxymethyl penicillin (n: 9), cefdinir (n: 1), and cefixime (n: 1), while there was no reaction in the controlled administration with clindamycin. Alternative treatments were tested in 13 patients with a confirmed ceftriaxone allergy. No adverse reactions were observed in 9 patients who underwent DPT with ACA and in 10 patients who were exposed to clarithromycin under controlled conditions. Finally, 54 of the 80 patients (67.5%) were successfully contacted and none reported a reaction to the alternative drugs.
Conclusion: For patients with confirmed BLA, macrolides may be considered as preferred alternatives. In addition, beta-lactams with different side chains may be safe alternatives after diagnostic evaluation, taking into account the risk of cross-reactivity.
