WHAT IS KNOWN AND OBJECTIVE: In recent years, the resistance of Mycoplasma pneumoniae to macrolide antibiotics has increased significantly. The health systems are facing significant challenges in carrying out the diagnosis and treatment of refractory Mycoplasma pneumoniae pneumonia in children. Levofloxacin is suitable for treating infectious diseases in various systems but limited in children due to arthropathy issues in weight-bearing joints. This study aimed to evaluate the efficacy and safety of levofloxacin in children with macrolide-resistant Mycoplasma pneumoniae pneumonia. METHODS: We retrospectively enrolled six confirmed cases of refractory Mycoplasma pneumoniae pneumonia who were admitted in the paediatric respiratory ward of Shandong provincial hospital Affiliated to Shandong first Medical University between 1st January 2020 and 29th February 2020. Levofloxacin was given to the patients through the intravenous or oral route as per the following dosages :<5 years, 8-10 mg/kg q12 h; >5 years, 8-10 mg/kg, qd for 10 days. The clinical data were collected and analysed. RESULTS AND DISCUSSION: The average age of the enrolled cases was six years and nine months (range, four years, and seven months to eleven years and seven months). All cases were found to be drug-resistant and were treated with azithromycin combined with antibacterial drugs. Levofloxacin was used in the patient's refractory to macrolide antibiotics. The temperature of five cases returned to normal 1-2 days after treatment with levofloxacin, and the imaging of the four cases showed expected improvements. The gastrointestinal symptoms, neurological manifestations, joint symptoms, blood parameters, liver and kidney functions, and exercise conditions of the children were closely monitored. The follow-up time of the patients ranged from one week to five months. No drug-related adverse reactions were observed in patients during treatment or during follow-up. WHAT IS NEW AND CONCLUSION: The clinical symptoms and imaging significantly improved after treatment with levofloxacin, and no drug-related adverse reactions were observed. Levofloxacin proved to be an effective and safe drug in the treatment of children with macrolide-resistant mycoplasma pneumonia. This study will provide a reference for evaluating the efficacy and safety of levofloxacin in the paediatric population.
