Rescreening for abnormal vaginal flora in pregnancy and re-treating with clindamycin vaginal cream significantly increases cure and improvement rates.

We investigated 199 pregnant women with bacterial vaginosis (BV) who received clindamycin vaginal cream (CVC) for three days and compared with 205 women treated with placebo. The vaginal flora was assessed at each visit. At the second visit, 71% in the CVC group were cured/improved, compared with 12% in the placebo group (P < 0.001). At visit 3 about 90% who responded to initial CVC treatment were still cured/improved. Of women who initially failed to respond to CVC and were given an additional seven-day course, 33% were cured/improved by the third visit, compared with 15% who failed to respond to placebo initially and were given a further seven-day course (P = 0.02). By visit 4, half the women in the CVC group who received additional treatment remained cured/improved, compared with 26% who had additional placebo (P = 0.004). In the CVC group, a change from abnormal to normal rose from 71% (visit 2) to 76% (visit 3) and 79% (visit 4). A similar trend was seen in women who received placebo but the proportions were significantly lower (12%, 24% and 33%, respectively). There is value in rescreening and re-treating women who remain BV-positive after initial clindamycin treatment.
