Recurrent Bacterial Vaginosis

Recurrent bacterial vaginosis is a common condition in women of reproductive age and is characterized by a disruption of the normal vaginal microbiota, with a reduction in Lactobacillus species and an overgrowth of anaerobic bacteria such as Gardnerella vaginalis. Recurrence rates after standard antibiotic treatment are high. Lactobacillus crispatus is considered one of the most protective species for maintaining vaginal microbiota balance. This multicenter, randomized, double-blind, placebo-controlled clinical trial aims to evaluate the efficacy and safety of a probiotic supplement containing Lactobacillus crispatus CRP21 (Crispavag® capsules) in reducing the incidence of recurrent bacterial vaginosis in women diagnosed with recurrent bacterial vaginosis. After standard antibiotic treatment, participants will be randomly assigned in a 1:1 ratio to receive either the probiotic supplement or a placebo for 12 weeks. The primary objective is to evaluate whether supplementation with Lactobacillus crispatus CRP21 reduces the incidence of recurrent bacterial vaginosis episodes compared with placebo. Participants will be followed for a total of 24 weeks, including a 12-week treatment period and a 12-week follow-up period.

This is a randomized trial of vaginal microbiome transplant vs. saline placebo to restore a Lactobacillus dominant vaginal microbial community in women with recurrent bacterial vaginosis.

This clinical trial is looking at how well and safely the vaginal administration of Vagitab-T works . Vagitab-T is already on the market in several countries in Europe as a medical device. The main goals of this trial are to see if the recurrence rate of bacterial vaginosis goes down during the study, if it helps balance the altered vaginal flora during antibiotic treatment, if it improves vaginal secretions, and if vaginal microflora return to normal. We'll also ask the participants about their quality of life and whether they think the treatment is safe. All 30 women will get the same treatment, and there's no comparison group. They'll be treated with Vagitab-T vaginal tablets for three monthly cycles. Also, metronidazole will be taken at the start of the study for seven days. Participants will sign an informed written consent and we'll visit them at the start (day 0) and end (day 90) of the study. In addition, we'll call them during each of the three cycles of treatment.
