Brief Summary:
Bacterial vaginosis (BV) is a common, complex clinical syndrome characterized by alterations in the normal vaginal flora. Bacterial vaginosis has been associated with a variety of adverse health outcomes including endometritis; post-abortion endometritis; nongonococcal, nonchlamydial pelvic inflammatory disease; and an increased risk of acquiring and transmitting HIV infection. In pregnancy, BV is associated with premature rupture of the membranes, chorioamnionitis, amniotic fluid infection, preterm labor, preterm birth, and postpartum endometritis. Several studies have documented increased postpartum complications in the newborn and infants. The etiology of BV is poorly understood but recurrence is quite common despite treatment. Documented recurrence rate of up to 30% within three months are reported. Small studies have shown that adding vaginal acidifying gel to standard antibiotic regimens may reduce recurrence rates of BV. We plan an RCT comparing standard antibiotic therapy to antibiotics plus vaginal acidifying gel. Our hypothesis is that the addition of an acidifying gel will decrease the chance of recurrence of BV within 3 months.

Condition or disease Intervention/treatment Phase
Bacterial Vaginosis Drug: Vaginal acidifying gel (RepHresh) Drug: Metronidazole control Not Applicable

Detailed Description:
Women with recurrent BV will be randomly assigned to standard care of metronidazole vs metronidazole plus vaginal acidifying gel. Symptoms and presence of BV will be measured at followup.

Arm Intervention/treatment
Experimental: Metronidazole plus gel
Receive metronidazole plus vaginal gel
Drug: Vaginal acidifying gel (RepHresh)
placement of vaginal acidifying gel into vagina to restore "normal" vaginal pH.
Other Name: RepHresh vaginal gel.

Active Comparator: Control- metronidazole alone
Oral Metronidazole antibiotic therapy alone
Drug: Metronidazole control
oral metronidazole therapy alone
Other Name: metronidazole

Primary Outcome Measures :
  1. Recurrent Bacterial Vaginosis [ Time Frame: 3 months ]
    Recurrence by either Amsel's or Nugent's criteria. Amsel's criteria are the presence of 3 of 4 of following: 1. homogenous gray-white vaginal discharge, 2. elevated vaginal pH >4.7, 3. presence of at least 20% of vaginal epithelial cells being clue cells on wet prep microscopy, and 4. positive amine odor test on addition of 10% KOH. Nugent's criteria is based on microscopy and bacterial scoring of lactobaccilus, gardnerella, and curved gram-variable rods. A score of at least 7 is indicative of bacterial vaginosis.
