Treatment and management of bacterial vaginosis in pregnancy: current and future perspectives.
Bacterial vaginosis accounts for the majority of cases of vaginal discharge and has been consistently linked to an increased risk of preterm delivery. Bacterial vaginosis is characterized by the reduced number or absence of hydrogen peroxide-producing Lactobacillus spp., which promotes the overgrowth of anaerobic bacteria, including Gardnerella vaginalis, Mycoplasma hominis, Bacteroides spp., and Mobiluncus spp. Black race, higher-risk sexual activity, frequent vaginal douching and the substantial reduction of hydrogen peroxide-producing Lactobacillus spp. are the main predictors of bacterial vaginosis development. Clinical- and laboratory-based bacterial vaginosis diagnostic tests are widely used to screen for bacterial vaginosis but, more recently, office-based bacterial vaginosis screening tools have been developed. Although systemic treatment for bacterial vaginosis with metronidazole or clindamycin has been demonstrated to be effective in the short-term cure of bacterial vaginosis, recurrence of bacterial vaginosis within 3 months of treatment is common, and treatment for bacterial vaginosis using these strategies has not been effective in reducing the risk of preterm delivery.
