[Mycobacterium abscessus infection management: Macrolide and quinolone desensitization]

Antibiotic hypersensitivity reactions can lead to marked morbidity, mortality and inadequate treatment options. Mycobacterium abscessus infection is a difficult management system for clinicians since it most commonly involves the lungs, progresses if untreated, and the organism is resistant to many antibiotics, as well as the agents used in treatment can cause undesirable side effects. Although macrolides are one of the most reliable antibiotic groups in terms of allergic reactions, early type hypersensitivity reactions against macrolides, one of the main antibiotics used in the treatment of Mycobacterium abscessus lung disease, may make the treatment management of the disease difficult. Due to the rapid increase in the use of quinolone in recent years, the frequency of developing allergic reactions with these agents also increases. In cases where antibiotic hypersensitivity is detected, the use of the responsible agent should be avoided, but desensitization may be necessary in cases without different treatment options. In this study, it was aimed to present a case of successful desensitization with clarithromycin and moxifloxacin in a patient who was diagnosed with Mycobacterium abscessus lung disease and developed anaphylaxis with clarithromycin and moxifloxacin after treatment was initiated.
