Treatment considerations for bacterial vaginosis and the risk of recurrence.

Abstract Background: Recommended regimens for the treatment of bacterial vaginosis (BV) have similar efficacy; thus, the choice of treatment should consider additional factors such as risk of BV recurrence and side effect profile. The purpose of this study was to investigate BV recurrence rates and rates of acquiring vulvovaginal candidiasis (VVC) after different BV treatments in a commercially insured population. Methods: Private administrative insurance claims from 2004 to 2006 were used. Study subjects were continuously enrolled females 12–50 years of age who filled prescriptions for BV treatment (n = 32,268). The four BV treatments (single-dose clindamycin vaginal cream (2%), multiple-dose clindamycin vaginal regimens, vaginal metronidazole, and oral metronidazole) were compared for rates of recurrent BV and VVC after treatment using multivariate analyses. Covariates included sociodemographic and clinical characteristics. Results: Overall, the rate of BV recurrence (2.7%), and VVC posttreatment (2.9%)...
