Anaerobic vaginosis (non-specific vaginitis): clinical, microbiological, and therapeutic findings.

The effect of metronidazole on anaerobic vaginosis (non-specific vaginitis) was assessed in a double-blind, placebo-controlled study of 40 women. 19 of 20 women given metronidazole 400 mg twice a day for seven days were clinically and microbiologically cured by the time they completed treatment. All 20 women given a placebo were treatment failures, but when they were given a single 2 g dose of metronidazole, 15 showed clinical and microbiological cure a week later. 14 of the responders showed a recurrence of infection a month after treatment; this was probably due to reinfection, although persistence of infection cannot be ruled out. Findings in the clinic correlated closely with subsequent microbiological results in 133 out of 140 patient-visits, which suggests that there is no need for expensive and time-consuming laboratory investigations in this condition.
