简要总结
This study is a single-center, open-label clinical trial designed to evaluate the early bactericidal activity (EBA) of sitafloxacin against Mycobacterium abscessus disease. Patients with Mycobacterium abscessus disease were enrolled and treated with sitafloxacin monotherapy for 14 days. Colony forming units (CFU) and time to positivity (TTP) in sputum cultures were analyzed and compared. By assessing the impact of sitafloxacin monotherapy on the bacteria in the sputum of patients with Mycobacterium abscessus disease, the early bactericidal activity of sitafloxacin was evaluated, providing a basis for the selection of new drugs for the treatment of Mycobacterium abscessus disease.

They will be administered sitafloxacin continuously for 14 days, and sputum samples will be collected for colony-forming units counting and time to positivity observation to evaluate the efficacy of the antibacterial agent.
Study Medication: Sitafloxacin 100mg once daily for 14 days.
干预措施: Sitafloxacin (Drug)
结局指标
主要结局
Early bactericidal activity
时间窗: 14 days
Patients with Mycobacterium abscessus infections were enrolled and treated with sitafloxacin monotherapy for 14 days to assess its early bactericidal activity. This involved analyzing and comparing the colony-forming units and time to positivity in sputum cultures to evaluate the impact of sitafloxacin on the bacteria in the sputum of patients with Mycobacterium abscessus infections.
