ABSTRACT
To clarify the clinical efficacy of STFX for patients with non-gonococcal urethritis (NGU), including chlamydial urethritis and Mycoplasma genitalium-positive urethritis, this study included male patients with NGU who were 20 years old or older. The pathogens, including Chlamydia trachomatis, M. genitalium and Ureaplasma urealyticum, were detected by nucleic acid amplification tests and the patients were treated with sitafloxacin 100 mg twice daily for 7 days. Microbiological and clinical efficacies were assessed for the patients with NGU posttreatment. Among the 208 patients enrolled in this study, data for a total of 118 patients could be analyzed. The median age was 32 (20-61) years. The median duration from the completion of treatment to the second visit was 21 (14-42) days. There were 68 pathogen-positive NGU cases and 50 with NGU without any microbial detection. Microbiological cure was achieved in 95.6% of the pathogen-positive NGU patients. Total clinical cure was achieved in 91.3% (105/115). In this study, STFX was able to eradicate 95.7% of C. trachomatis, 93.8% of M. genitalium and 100% of U. urealyticum. The results of our clinical research indicate that the STFX treatment regimen should become a standard regimen recommended for patients with NGU. In addition, this regimen is recommended for patients with M. genitalium-positive NGU.
