BV Recurrence Solved? New Insights Emerge
1 Oct
Summary
- Two pathways, persistence and re-infection, identified for recurrent BV.
- Concurrent treatment of partners reduced BV recurrence by over 60%.
- Intrauterine devices may contribute to BV persistence in some women.
Melbourne researchers have identified two primary factors contributing to persistent bacterial vaginosis (BV) infections in women: the condition's resistance to antibiotic treatment and re-infection from male partners.
A study involving 188 couples found that concurrently treating both partners with antibiotics reduced BV recurrence by more than 60%. However, approximately one-third of women still experienced recurrence, with their microbiomes indicating an incomplete clearance of BV before resuming sexual activity.
This new research highlights that persistence and re-infection are distinct, though not mutually exclusive, pathways to recurrent BV. Scientists are now exploring longer antibiotic courses and combinations to achieve higher cure rates and prevent multiple treatments per year.
Further investigation is needed into the role of intrauterine devices (IUDs), as the study found they might enhance BV persistence in some women. The findings, while representative of urban Australia, may not be universally applicable to global populations.
