The effects of antimicrobial therapy on bacterial vaginosis in non-pregnant women

Abstract

Bacterial vaginosis (BV) is a very common cause of symptomatic and asymptomatic vaginal infection. It has been associated with a high incidence of obstetric and gynaecologic complications and an increased risk of transmission of HIV (human immunodeficiency virus). This review evaluated the effectiveness and adverse effects of antimicrobial agents used to treat BV in non-pregnant women. Twenty-four trials involving 4422 women were reviewed. With regard to less treatment failure, clindamycin was superior to placebo but comparable to metronidazole, irrespective of the dose regimen. Metronidazole tended to cause a higher rate of adverse events, such as metallic taste and nausea and vomiting, than did clindamycin. Oral lactobacillus combined with metronidazole was more effective than metronidazole alone. Administered in an intravaginal gelatin tablet, lactobacillus was also more effective than oral metronidazole. Triple sulfonamide cream was less effective compared with clindamycin. Hydrogen peroxide douche was not as effective as a single 2 g dose of metronidazole yet caused more harms. Only one trial involved asymptomatic women and the result was not conclusive. There was insufficient evidence to reach a conclusion on the effectiveness of other promising drugs. Drugs effective for bacterial vaginosis include clindamycin preparations, oral metronidazole, and oral and intravaginal tablets of lactobacillus. Adverse effects of metronidazole include metallic taste, and nausea and vomiting. Information on possible side effects of lactobacillus preparations is required.
