An update on the role of Atopobium vaginae in bacterial vaginosis: what to consider when choosing a treatment? A mini review

INTRODUCTION: Bacterial vaginosis (BV) is the most common vaginal disorder in reproductive-age women. The condition is characterised by the replacement of a healthy, lactobacilli-dominated vaginal microbiota by anaerobic and facultative anaerobic bacteria. BV increases the risk of acquisition of STIs and is associated with pregnancy complications. Although the composition of the bacteria in BV varies between individuals, there are some species such as Gardnerella, Atopobium, Mycoplasma, Snethia, Megasphera, Dialister, etc., that are found most frequently. MATERIAL AND METHODS: Literature research to the importance of Atopobium vaginae in BV and treatment options. RESULTS: Atopobium (A.) vaginae is an important component of the complex abnormal vaginal flora in BV; even though A. vaginae, like Gardnerella vaginalis, has also been detected in the normal flora, it is much more common in BV patients. A. vaginae has been shown to play an important role in the pathophysiology of BV and is thought to be at least a partial cause of the known negative sequelae. The presence of A. vaginae in the BV-associated biofilms and its resistance to some antimicrobial substances has been described - this seems to have a major impact on treatment outcome. CONCLUSION: Current scientific data demonstrate that dequalinium chloride (Fluomycin(®)) is one of the valid therapeutic options for BV treatment, since it displays a broad antimicrobial spectrum against relevant vaginal pathogens, especially against G. vaginalis and A. vaginae, without having safety concerns.
