A groundbreaking study published in The New England Journal of Medicine has provided compelling evidence that bacterial vaginosis (BV), a condition affecting nearly one-third of women worldwide, can be transmitted sexually. The findings have sparked discussions among experts about shifting the treatment paradigm to include both men and women rather than focusing solely on women.
Study Findings
The study, published on March 5, was led by Lenka A. Vodstrcil, PhD, and colleagues at the Melbourne Sexual Health Centre, Monash University in Australia. Their research examined 164 couples in monogamous relationships where the woman had BV. The study compared the effectiveness of treating both partners versus treating only the woman.
The results were striking: BV recurrence occurred in only 35% of women in the partner-treatment group compared to 63% in the control group. The trial was halted early because treating only the woman was found to be significantly less effective than treating both partners.
“This successful intervention is relatively cheap and short and has the potential to not only improve BV cure rates for women but also open up exciting new opportunities for BV prevention,” said co-author Catriona S. Bradshaw, PhD.
Experts Call for Further Research
While the study’s findings are significant, some researchers urge caution and further investigation. Mykhaylo Usyk, PhD, of Albert Einstein College of Medicine, acknowledges that BV can be transmitted sexually but stresses the need for more research to identify which specific types of BV are transmissible.
Additionally, Rebecca Brotman, PhD, of the University of Maryland School of Medicine, noted that factors such as smoking and intravaginal practices like douching may also contribute to BV development. She acknowledged that while the study offers strong evidence supporting BV’s sexual transmission, more research is needed to confirm these results across diverse populations.
Implications for Treatment and Counseling
Experts believe these findings could revolutionize how BV is treated. Caroline M. Mitchell, MD, MPH, of Massachusetts General Hospital, emphasized that while BV is a complex syndrome with varying causes, the study presents a compelling case for treating both partners in cases of recurrent BV.
“Since treatment options haven’t substantively changed since 1982, this is a huge win for women,” she said.
An accompanying editorial by Christina A. Muzny, MD, MSPH, and Jack D. Sobel, MD, underscored the importance of changing how healthcare providers counsel women about BV. They advocated for greater involvement of male partners in both treatment and prevention strategies, as well as consistent condom use to help reduce transmission.
Conclusion
This study marks a pivotal moment in BV research, suggesting a shift in medical treatment approaches. While further research is needed to fully understand BV transmission, these findings represent a significant step toward more effective treatment strategies for millions of women worldwide.
