Maternal Effects of Bacterial Vaginosis (BV) Treatment in Pregnancy

• preterm delivery
• low birth weight
• chorioamnionitis

The goal of this study is to examine acceptability and efficacy of 2 kinds of BV treatment among women at low risk for preterm delivery. The objectives are:

1. To examine the side effects and patient acceptability of oral versus intravaginal metronidazole.
2. To compare the efficacy of oral and intravaginal metronidazole for the treatment of BV
3. To study the efficacy of oral and intravaginal metronidazole for the prevention of hospital admission during the 3rd trimester, chorioamnionitis, preterm delivery, and maternal infectious morbidity.

This is a randomized, placebo-controlled intervention trial. Women diagnosed as BV+ by Gram stain at 12-16 weeks gestation are randomly assigned to the following treatment groups: oral metronidazole (250 mg TID x 7 days) with intravaginal placebo; intravaginal metronidazole (5g 0.75% gel BID x 5 days) with oral placebo. African American, Hispanic, Asian/Pacific Islander, Native American, and white women are eligible. Women with a prior preterm delivery, multiple gestation, chronic hypertension or pre-existing diabetes, antibiotic use before enrollment in the study, allergy to metronidazole, history of alcohol abuse in past year, and women under age 18 are excluded.
