Bacterial vaginosis diagnosis and treatment in postmenopausal women: a survey of clinician practices.

ABSTRACT: OBJECTIVE:Some diagnostic features of the genitourinary syndrome of menopause (GSM) and bacterial vaginosis (BV) overlap, such as low levels of vaginal Lactobacillus and pH?>?5. We sought to determine clinicians' diagnostic and treatment practices for postmenopausal women presenting with BV and GSM scenarios and how commercial molecular screening tests are utilized. METHODS:Anonymous surveys were sent to practicing women's health clinicians to evaluate assessment and treatment strategies for postmenopausal women presenting with BV and GSM scenarios. RESULTS:When given a scenario of a postmenopausal woman with symptoms overtly positive for BV, a majority of providers (73%) would conduct a wet mount, though only 35% would evaluate full Amsel's criteria. A majority (89%) recommended treatment with antibiotics, 28.2% recommended vaginal estrogen in addition to antibiotics, and 11.8% recommended vaginal estrogen alone. Of providers who would use a molecular swab, 30% would wait for results before treating the patient's symptoms. When given a scenario of a postmenopausal woman presenting with GSM, a majority (80%) recommended vaginal estrogen, and only 4.6% recommended antibiotics. Few (16%) responders would evaluate with a molecular swab, half of whom would wait for results before prescribing treatment. Clinicians in practice for less than 10 years were more likely to rely on molecular swabs than those who had been practicing longer (P?

Project description:Identifying modifiable factors that increase women's vulnerability to HIV is a critical step in developing effective female-initiated prevention interventions. The primary objective of this study was to pool individual participant data from prospective longitudinal studies to investigate the association between intravaginal practices and acquisition of HIV infection among women in sub-Saharan Africa. Secondary objectives were to investigate associations between intravaginal practices and disrupted vaginal flora; and between disrupted vaginal flora and HIV acquisition.We conducted a meta-analysis of individual participant data from 13 prospective cohort studies involving 14,874 women, of whom 791 acquired HIV infection during 21,218 woman years of follow-up. Data were pooled using random-effects meta-analysis. The level of between-study heterogeneity was low in all analyses (I(2) values 0.0%-16.1%). Intravaginal use of cloth or paper (pooled adjusted hazard ratio [aHR] 1.47, 95% confidence interval [CI] 1.18-1.83), insertion of products to dry or tighten the vagina (aHR 1.31, 95% CI 1.00-1.71), and intravaginal cleaning with soap (aHR 1.24, 95% CI 1.01-1.53) remained associated with HIV acquisition after controlling for age, marital status, and number of sex partners in the past 3 months. Intravaginal cleaning with soap was also associated with the development of intermediate vaginal flora and bacterial vaginosis in women with normal vaginal flora at baseline (pooled adjusted odds ratio [OR] 1.24, 95% CI 1.04-1.47). Use of cloth or paper was not associated with the development of disrupted vaginal flora. Intermediate vaginal flora and bacterial vaginosis were each associated with HIV acquisition in multivariable models when measured at baseline (aHR 1.54 and 1.69, p<0.001) or at the visit before the estimated date of HIV infection (aHR 1.41 and 1.53, p<0.001), respectively.This study provides evidence to suggest that some intravaginal practices increase the risk of HIV acquisition but a direct causal pathway linking intravaginal cleaning with soap, disruption of vaginal flora, and HIV acquisition has not yet been demonstrated. More consistency in the definition and measurement of specific intravaginal practices is warranted so that the effects of specific intravaginal practices and products can be further elucidated.

Project description:BackgroundBacterial vaginosis-a condition defined by a shift from Lactobacillus dominance to a polymicrobial, anaerobic bacterial community-increases the risk of acquiring sexually transmitted infections and other complications of the female reproductive tract. Antibiotic treatment frequently fails to return the microbiome to an optimal Lactobacillus-dominated state. No criteria currently exist to identify the patients likely to experience treatment failure.ObjectiveWe sought to identify the pretreatment community signatures associated with treatment failure through 16S ribosomal RNA gene analysis.Study designTwenty-eight women who were enrolled in an oral metronidazole treatment trial of bacterial vaginosis were studied. Cervicovaginal lavage samples were collected before metronidazole treatment and at 7 and 30 days posttreatment. Cervicovaginal lavage DNA was amplified and sequenced using a paired-end, V4 region 2×150 MiSeq run.ResultsOf the 28 women, 25% failed to clear bacterial vaginosis; 35.7% demonstrated a transient clearance, shifting to community-type 2 (Lactobacillus iners dominant) at visit 2 only; 7.1% demonstrated a delayed clearance, reaching community-type 2 at the final visit only; and 32.1% of patients experienced sustained bacterial vaginosis clearance. Examination of the community composition and structure demonstrated that both the richness and the evenness were significantly lower for the women who experienced sustained clearance, whereas the women who failed to clear bacterial vaginosis possessed the highest median levels of richness, evenness, and diversity pretreatment. Soluble immune factors in the lower reproductive tract improved significantly following a shift from community-type 4 to a Lactobacillus-dominant microbiome, with the samples categorized as community-type 2 possessing significantly higher levels of secretory leukocyte protease inhibitor, growth-regulated alpha protein, and macrophage inflammatory protein-3 and significantly lower levels of intercellular adhesion molecule-1. Although the shifts to Lactobacillus dominance improved the markers of mucosal tissue health, these gains were only temporary among the women who experienced recurrence.ConclusionAssemblies of highly diverse microbiota are associated with the enhanced resilience of bacterial vaginosis to standard metronidazole treatment. These communities may be foundational to treatment resistance or simply an indication of a well-established community made possible by canonical biofilm-forming taxa. Future studies must target the transcriptional activity of these communities under the pressure of antibiotic treatment to resolve the mechanisms of their resistance.

Project description:BACKGROUND: In recent years several new fastidious bacteria have been identified that display a high specificity for BV; however no previous studies have comprehensively assessed the behavioural risk associations of these bacterial vaginosis-candidate organisms (BV-COs). METHODS: We examined the associations between 8 key previously described BV-COs and BV status established by Nugent's score (NS). We also examined the sexual practices associated with each BV-CO. We incorporated 2 study populations: 193 from a sexually-inexperienced university population and 146 from a highly sexually-active clinic population. Detailed behavioural data was collected by questionnaire and vaginal smears were scored by the Nugent method. Stored samples were tested by quantitative PCR assays for the 8 BV-COs: Atopobium vaginae, Gardnerella vaginalis, Leptotrichia spp., Megasphaera type I, Sneathia spp., and the Clostridia-like bacteria BVAB1, BVAB2 and BVAB3. Associations between BV-COs and BV and behaviours were examined by univariate and multivariable analyses. RESULTS: On univariate analysis, all BV-COs were more common in BV compared to normal flora. However, only Megasphaera type I, BVAB2, A. vaginae and G. vaginalis were significantly independently associated with BV by multivariable analysis. Six of the eight BV-COs (Megasphaera type I, BVAB2, BVAB3, Sneathia, Leptotrichia and G. vaginalis) were rare or absent in sexually-unexposed women, and demonstrated increasing odds of detection with increasing levels of sexual activity and/or numbers of lifetime sexual partners. Only G. vaginalis and A. vaginae were commonly detected in sexually-unexposed women. Megasphaera type I was independently associated with women-who-have-sex-with women (WSW) and lifetime sexual partner numbers, while unprotected penile-vaginal-sex was associated with BVAB2 detection by multivariate analysis. CONCLUSIONS: Four of eight key BV-COs were significantly associated with BV after adjusting for the presence of other BV-COs. The majority of BV-COs were absent or rare in sexually-unexposed women, and associated with increasing sexual exposure, suggesting potential sexual transmission of BV-COs.
