This study aimed to assess the possible association of bacterial vaginosis (BV) and early miscarriage in 408 women undergoing intracytoplasmic sperm injection (ICSI) for reasons of male infertility. A vaginal sample was obtained before oocyte retrieval and evaluated for BV-associated bacteria using the Nugent scoring system. The primary outcome was early miscarriage and the secondary outcomes included implantation, pregnancy, late miscarriage, preterm delivery and live birth rates. Chi-square, ANOVA, relative risk and odds ratio were used for data analysis where appropriate...

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...

The aim of the present study was to develop thermoplastic polyurethane (TPU)-based intravaginal rings (IVRs) for prophylaxis and treatment of bacterial vaginosis via hot melt extrusion/injection molding. Therefore, different TPU grades were processed in combination with lactic acid or metronidazole, targeting a sustained lactic acid release over a 28day-period and sustained metronidazole release over 4-7days. Hot melt extrusion of lactic acid/TPU combinations required a lower extrusion temperature due to the plasticizing properties of lactic acid, evidenced by the lower glass transition temperature (Tg) and cross-over point (Ttanδ=1) values...

Bacterial vaginosis is the most common gynecological disorder affecting women of reproductive age. Bacterial vaginosis is frequently associated with the development of a Gardnerella vaginalis biofilm. Recent data indicates that G. vaginalis biofilms are more tolerant to antibiotics and are able to incorporate other bacterial vaginosis -associated species, yielding a multi-species biofilm. However, despite its apparent role in bacterial vaginosis, little is known regarding the molecular determinants involved in biofilm formation by G...

Objectives: To determine associations, if any, of bacterial vaginosis with cervical pre-neoplastic lesions and evaluate any effects of sub-categorization of smears with bacterial vaginosis. Methods: All cervico-vaginal smears reported as positive for bacterial vaginosis over a five-year period were reviewed and sub-categorized into ‘type I (dysbacteriosis)’ and ‘type II (pure Gardenerella infection)’ smears by two cytopathologists (PS, SG). The proportion of smears with healthy flora and pre-neoplastic lesions was compared with those having bacterial vaginosis in conjunction with such changes...

Gynecological health is a challenge in low-income countries. Personal opposition to perineal examination has been overcome by the use of vaginal self-sampling. Here, we review the use of this procedure notably in low-income countries and the main infectious causes of miscarriage. Vaginal self-sampling was mainly used for human papillomavirus detection but also to detect microorganisms causing sexually transmitted infections or bacterial vaginosis. 58 studies have been performed in low-resource countries, mainly studies performed to detect human papillomavirus in urban and peri-urban areas and demonstrating excellent acceptability...
