REVIEW
Jennifer Velloza, Renee Heffron
PURPOSE OF REVIEW: This review describes existing evidence addressing the potential modulation of pre-exposure prophylaxis (PrEP) products, specifically 1% tenofovir (TFV) gel and oral tenofovir-based PrEP, by vaginal dysbiosis and discusses future considerations for delivering novel, long-acting PrEP products to women at high risk for vaginal dysbiosis and HIV. RECENT FINDINGS: We describe results from analyses investigating the modification of PrEP efficacy by vaginal dysbiosis and studies of biological mechanisms that could render PrEP ineffective in the presence of specific microbiota...

BACKGROUND: The urinary microbiota is similarly complex as the vaginal and penile microbiota, yet its role as a reservoir for pathogens and for recurrent polymicrobial biofilm diseases like bacterial vaginosis (BV) is not clear. RESULTS: Here, we analysed the urinary microbiota of healthy men and women and compared it with that of women during BV and after antibiotic treatment using next-generation sequencing of the 16S rRNA gene V1-V2 regions. Eight different community types, so called urotypes (UT), were identified in healthy humans, all of which were shared between men and women, except UT 7, dominated in relative abundance by Lactobacillus crispatus, which was found in healthy women only...

Kingella kingae, producing the cytotoxic RTX protein, is a causative agent of serious infections in humans such as bacteremia, endocarditis and osteoarticular infection, especially in young children. Recently, Kingella negevensis, a related species, has been isolated from the oral cavity of healthy children. In this study, we report the isolation of K. negevensis strain eburonensis, initially misidentified as K. kingae with MALDI-TOF MS, from a vaginal specimen of a patient suffering of vaginosis. The genome sequencing and analysis of this strain together with comparative genomics of the Kingella genus revealed that K...

PURPOSE: Cervicovaginal Atopobium vaginae and Gardnerella vaginalis are strongly associated with bacterial vaginosis (BV) and are the main components of vaginal biofilms. The low efficacy of BV treatment with metronidazole may be due to the presence of such biofilms. Thus, the aim of this study was to compare the pretreatment cervicovaginal loads of A. vaginae and G. vaginalis for women who restored normal flora and those who persisted with BV after a full course of oral metronidazole...

Intravaginal practices (IVPs) are common in Zambia and are usually practiced for hygiene, partner pleasure, and health. IVPs are associated with HIV acquisition, changes in the vaginal flora, and bacterial vaginosis (BV), making it important to understand the decision-making process behind IVP engagement. The Women's and Sexual Health (WASH) intervention decreased IVP engagement among HIV-infected Zambian women, though change in reasons for engagement has not been assessed. We used conjoint analysis (CA) to quantify the decision-making process of IVP engagement and evaluated how the WASH intervention impacted these factors...

BACKGROUND: Daily oral tenofovir-based pre-exposure prophylaxis (PrEP) is high efficacious for HIV prevention among women with high adherence. However, the effect of abnormal vaginal microbiota on PrEP efficacy is of concern. We investigated whether bacterial vaginosis modified the efficacy of oral PrEP. METHODS: We used prospectively collected data from women in the Partners PrEP Study, a placebo-controlled trial of daily oral PrEP (either tenofovir monotherapy or a combination of tenofovir and emtricitabine) in HIV serodiscordant couples aged 18 years or older in Kenya and Uganda that showed high efficacy in women...

WHO estimated that nearly 1 million people become infected every day with any of four curable sexually transmitted infections (STIs): chlamydia, gonorrhoea, syphilis, and trichomoniasis. Despite their high global incidence, STIs remain a neglected area of research. In this Commission, we have prioritised five areas that represent particular challenges in STI treatment and control. Chlamydia remains the most commonly diagnosed bacterial STI in high-income countries despite widespread testing recommendations, sensitive and specific non-invasive testing techniques, and cheap effective therapy...

Intravaginal practices (IVP) are linked to bacterial vaginosis (BV), obstetric/gynecological complications, and HIV. Late adolescent and young adult (LAYA) women in Zambia have high rates of HIV. Adult and mature (AM) HIV-infected women in Zambia engage in IVP for hygiene, health, and sexuality reasons; however, to our knowledge, IVP use among LAYA women has not been examined. This study compares IVP use between LAYA and AM women to identify age-specific factors to target when developing IVP reduction interventions for LAYA women...

More data are needed on the role of abnormal vaginal microbiota in the natural history of cervical human papillomavirus (HPV) infections. Our purpose was to study the prevalence of mixed flora (MF), bacterial vaginosis (BV) and yeast infection in women with known HPV outcomes during the 72-month follow-up (FU). Asymptomatic pregnant women (N = 329) were enrolled in the third trimester of their pregnancy. Pap smears and HPV genotyping samples were taken at baseline and at 12-, 24-, 36- and 72-month FU visits, with one additional sample at 2 months for HPV...

The five community state types (CSTs) first identified by Ravel et al. (2011) offered a powerful scheme to classify the states of human vaginal microbial communities (HVMC). The classification is a significant advance because it devised an effective handle to deal with the enormous inter-subject heterogeneity and/or intra-subject temporal variability, the quantification of which is extremely difficult but of critical importance such as the understanding of BV (bacterial vaginosis) etiology. Indeed, arguably the most plausible ecological hypothesis for interpreting the BV etiology heavily depends on the CST classification (Gajer et al...

Abnormal vaginal microbiota (AVM) or bacterial vaginosis (BV) might negatively impact reproductive outcomes of in vitro fertilization (IVF). However, before randomized controlled trials are initiated to investigate cause and effect, it is necessary to establish the optimal treatment for AVM. Metronidazole seems ineffective to treat the biofilm in AVM; thus, clindamycin could be suggested as a relevant antibiotic agent for future intervention based studies. In the present case report, we present the first longitudinal follow-up of the vaginal microbiota with molecular methods during and after oral clindamycin treatment...
