Underlying causes of recurrent bacterial vaginosis identified by Australian scientists
Summary
Australian scientists found two main reasons why bacterial vaginosis (BV), a vaginal infection, often comes back after treatment. They discovered that BV can persist even after antibiotics or be passed back from male partners, and they suggest new treatment plans that target both causes.Key Facts
- Bacterial vaginosis affects about one in four women worldwide and is caused by an imbalance of bacteria in the vagina.
- Previous research showed that treating both women and their male partners with antibiotics lowered BV return rates by over 60%.
- The new study included 188 couples who received antibiotics; women took oral antibiotics, men took oral and topical treatments.
- Two reasons for BV returning were found: the infection not fully clearing after treatment, and reinfection from partners.
- About two-thirds of women had a healthy balance of bacteria after treatment, but one-third did not fully clear the infection and were almost three times more likely to get BV again soon.
- The study found that using an intrauterine device (IUD) might increase the chance of BV staying after treatment, but more research is needed.
- Researchers plan to test longer, combined antibiotic treatments to prevent women from needing frequent courses.
- The study mainly represents urban Australian populations, so results may differ in other countries or poorer areas.
