Vaginal probiotic product reduce recurrence rate of bacterial vaginosis

A newly published double blind, randomised, placebo controlled study(1) shows that EcoVag, a patented vaginal probiotic product from the Danish company, Bifodan, significantly reduces the recurrence rate of Bacterial Vaginosis (BV) following antibiotic treatment.

BV is one of the most frequent vaginal infections and if left untreated may have severe gynaecological and obstetric consequences such as pelvic inflammatory disease, miscarriage and preterm delivery(2). Even if BV is successfully cured with commonly used antibiotics, the recurrence rate has been reported as high as 80% after 9 months(3).

The study involved 100 women diagnosed with BV. All women were given a standard antibiotic treatment with Clindamycin vaginal cream (Dalacin). On a randomised basis half of the cured women were treated with one EcoVag vaginal capsule and the other half with an identical placebo capsule per day for 10 days during 3 consecutive menstrual cycles to measure the impact on recurrent infection rates.

The study shows that the recurrent BV infection rate is significantly reduced for the women taking EcoVag. At the study completion, after 6 months 65% of the EcoVag treated women were still BVfree compared to 46% of the placebo treated women (p<0.05).

Comparison of the two groups regarding “time from cure to relapse” was also statistically significant (p<0.05).

Furthermore, the study also confirmed that EcoVag is safe to use.

The study was performed in accordance with GCP/ICH in Drammen, Norway by Principal investigator Assistant Professor, MD, PhD, Dr Per- Göran Larsson; “Too many women suffer from chronic or frequent recurring vaginal infections. The study shows that this particular probiotic product can reduce the risk of recurrent infections, and substantiates the potential of vaginal applied probiotics to positively influence urogenital health” says Dr. Per-Göran Larsson.

Erik Brandsborg, Director of Research & Development at Bifodan: “The results of the study are a very important milestone and corroborates with findings from in-vitro tests and several in-vivo pilot studies performed with the product. Summarizing the results from these trials, EcoVag is safe to use, can prevent women from getting recurrent BV infections and can offer relief to the many women who suffer from BV associated symptoms like itching and burning.

    How can we get the EcoVag here in the U.S?

  2. Louise Endago Louise Endago United States says:

    Several other studies have also demonstrated the efficacy of probiotics in the treatment of bacterial vaginosis. One such example is the titled the following by Kingsley et. al.

    Augmentation of antimicrobial metronidazole therapy of bacterial
    vaginosis with oral probiotic Lactobacillus rhamnosus GR-1 and
    Lactobacillus reuteri RC-14: randomized, double-blind,
    placebo controlled trial

    Although some of these studies have demonstrated the effectiveness of probiotics as a first-line treatment for bacterial vaginosis, it would appear in practice that probiotics are more suited for prophylaxis rather than treatment.

    The fact that probiotics reduced recurrence rates of BV in this study comes as no surprise to any practitioner who is versed in the field of BV, but it is helpful to know the extent of its effects, as outlined clearly in the results of this study.

    Many thanks
