ABSTRACT

ObjectivesWe evaluated how storing vaginal samples at room temperature in stabilising solutions versus immediate freezing affects 16S rRNA gene amplicon sequencing-based microbiota studies, aiming to simplify home and field collection. METHODS: Twenty participants self-collected six mid-vaginal swabs that were stored in two nucleic acid preservatives (three in modified Solution C2 (Qiagen) and three in Amies/RNALater (Sigma)) in January-February 2016. From each set, two were immediately frozen (-80°C) and one was shipped to the University of Idaho (Moscow, Idaho) with return shipping to the Institute for Genome Sciences (Baltimore, Maryland). Amplicon sequencing of the 16S rRNA gene was used to characterise the vaginal microbiota, VALENCIA was used to assign community state types (CSTs), and quantitative PCR (qPCR) of 16S rRNA genes was used to estimate bacterial abundance. Cohen's Kappa statistic was used to assess within-participant agreement. Bayesian difference of means models assessed within-participant comparisons between shipped and immediately frozen samples. RESULTS: There were 115 samples available for analysis. Average duration of transit for shipped samples was 8 days (SD: 1.60, range: 6-11). Within-participant comparisons of CSTs between shipped and immediately frozen samples revealed complete concordance (kappa: 1.0) for both preservative solutions. No significant differences comparing shipped and immediately frozen samples were found with taxon-level comparisons or bacterial abundances based on pan-bacterial qPCR. CONCLUSIONS: Short-term room temperature shipping of vaginal swabs placed in stabilising solutions did not affect vaginal microbiota composition. Home collection with mail-in of vaginal samples may be a reasonable approach for research and clinical purposes to assess the vaginal microbiota.

ABSTRACT

BACKGROUND: Syphilis epidemics among women and men-who-have-sex-with-men (MSM) may be connected, but these connections are poorly understood. Using egocentric network data from a U.S. urban MSM cohort, we examined socio-demographics, behaviors, and syphilis positivity among MSM with (1) direct (MSM who report sex with women, MSMW); (2) indirect (MSM who only report male partners, some of whom are MSMW, MSMO/W); and (3) no (MSM who only report male partners and whose partners only have sex with men, MSMO/O) connection to women. METHODS: Sexually-active MSM aged 18-45 years were administered behavioral and network interviews (recall period: three months) and syphilis/HIV testing. Syphilis positivity was defined as RPR titer >1:8. Modified Poisson regression was used to test for differences across groups. RESULTS: Among 385 MSM, 14.5% were MSMW and 22.3% were MSMO/W. MSMW and MSMO/W were significantly more likely than MSMO/O to report sex behaviors associated with increased syphilis acquisition/transmission risk, including: > 2 sex partners [MSMW aPR:1.28 (0.98-1.68); MSMO/W aPR:1.35 (1.09-1.69)], concurrent sex partners [MSMW aPR:1.50 (1.17-1.92); MSMO/W aPR:1.39 (1.11-1.74)], and for MSMW only, transactional sex [aPR:2.07 (1.11-3.88)]. Syphilis positivity was 16.4% and was lower among MSMW (9.4%) and MSMO/W (14.1%) than MSMO/O (18.5%), but differences were not significant. CONCLUSIONS: There may be considerable connectivity between MSM and female sex partners that could facilitate syphilis transmission, and behaviors that increase acquisition/transmission risk among MSMW and MSMO/W may be distinct from MSMO/O. Future work should focus on examining the context and temporal patterns of sex partnerships among MSMW and MSMO/W.

ABSTRACT

ABSTRACT: Chlamydia trachomatis (CT) is the most commonly reported sexually transmitted infection in the United States. Untreated urogenital infection in women can result in adverse sequelae such as pelvic inflammatory disease and infertility. Despite national screening and treatment guidelines, rates continue to rise; because most infections are asymptomatic, the actual prevalence of CT infection is likely significantly higher than reported. Spontaneous clearance of CT in women (in the absence of antibiotic treatment) has been described in multiple epidemiologic studies. Given the serious consequences and high prevalence of CT infection, there is growing interest in understanding this phenomenon and factors that may promote CT clearance in women. Spontaneous CT clearance is likely the result of complex interactions between CT, the host immune system, and the vaginal microbiota (i.e., the communities of bacteria inhabiting the vagina), which has been implicated in CT acquisition. Herein, we briefly review current literature regarding the role of each of these factors in spontaneous CT clearance, identify knowledge gaps, and discuss future directions and possible implications for the development of novel interventions that may protect against CT infection, facilitate clearance, and prevent reproductive sequelae.

ABSTRACT

We review key concepts in the diagnosis, treatment, and follow-up of individuals with neurosyphilis. We describe the epidemiology of syphilis in the United States, highlight populations that are markedly affected by this infection, and attempt to estimate the burden of neurosyphilis. We describe the cardinal clinical features of early and late (tertiary) neurosyphilis and characterize the clinical significance of asymptomatic neurosyphilis in the antibiotic era. We review the indications for cerebrospinal fluid (CSF) examination and the performance characteristics of different CSF assays including treponemal and lipoidal antibodies, white cell count, and protein concentration. Future biomarkers and the role of imaging are briefly considered. We review preferred and alternative treatments for neurosyphilis and evidence for their use, including evidence for the use of enhanced intramuscular benzathine penicillin G to supplement intravenous penicillin.

ABSTRACT

Syphilis is a bacterial infection caused by Treponema pallidum and is primarily transmitted via skin-to-skin or mucosal contact during sexual encounters, or through vertical transmission during pregnancy. Cases continue to rise globally across various demographic groups despite effective treatment and prevention interventions. We discuss the case of a 28-year-old cisgender man who presented with secondary syphilis 1 month after being inadequately treated for primary syphilis. Individuals can present with symptoms and signs of syphilis to clinicians of various subspecialties due to diverse clinical presentation. All health-care providers should be able to identify the common and less common manifestations of this infection, and adequate treatment and follow-up are crucial to preventing serious sequelae. Novel biomedical prevention interventions, such as doxycycline post-exposure prophylaxis, are on the horizon.

ABSTRACT

BACKGROUND: Up to 26% of urogenital Chlamydia trachomatis infections spontaneously resolve between detection and treatment. Mechanisms governing natural resolution are unknown. We examined whether bacterial vaginosis (BV) was associated with greater chlamydia persistence versus spontaneous clearance in a large, longitudinal study. METHODS: Between 1999 and 2003, the Longitudinal Study of Vaginal Flora followed reproductive-age women quarterly for 1 year. Baseline chlamydia screening and treatment were initiated after ligase chain reaction testing became available midstudy, and unscreened endocervical samples were tested after study completion. Chlamydia clearance and persistence were defined between consecutive visits without chlamydia-active antibiotics (n = 320 persistence/n = 310 clearance). Associations between Nugent score (0-3, no BV; 4-10, intermediate/BV), Amsel-BV, and chlamydia persistence versus clearance were modeled with alternating and conditional logistic regression. RESULTS: Of chlamydia cases, 48% spontaneously cleared by the next visit (310/630). Nugent-intermediate/BV was associated with higher odds of chlamydia persistence (adjusted odds ratio [aOR] = 1.89; 95% confidence interval [CI], 1.30-2.74), and the findings were similar for Amsel-BV (aOR 1.39; 95% CI, .99-1.96). The association between Nugent-intermediate/BV and chlamydia persistence was stronger in a within-participant analysis of 67 participants with both clearance/persistence intervals (aOR = 4.77; 95% CI, 1.39-16.35). BV symptoms did not affect any results. CONCLUSIONS: BV is associated with greater chlamydia persistence. Optimizing the vaginal microbiome may promote chlamydia clearance.

ABSTRACT

BACKGROUND: Bacterial vaginosis (BV) is a highly prevalent disorder of the cervicovaginal microbiota. Molecular-BV may put women at increased risk for adverse reproductive and obstetric outcomes. We investigated the association of HIV and pregnancy on the vaginal microbiota and associations with molecular-BV in women of reproductive age from Pune, India. SETTING: We studied vaginal samples from N = 170 women, including N = 44 nonpregnant HIV seronegative, N = 56 pregnant seronegative, N = 47 nonpregnant women with HIV (WWH), and N = 23 pregnant WWH, and collected data on clinical, behavioral, and demographic factors. METHODS: We used 16S rRNA gene amplicon sequencing to characterize the composition of the vaginal microbiota. We classified the vaginal microbiota of these women into community state types based on bacterial composition and relative abundance and further categorized them into molecular-BV versus Lactobacillus -dominated states. To determine associations between pregnancy and HIV status with outcome of molecular-BV, logistic regression models were used. RESULTS: There was a high prevalence of molecular-BV (30%) in this cohort. We found that pregnancy was associated with decreased odds of molecular-BV (adjusted OR = 0.35, 95% CI: 0.14 to 0.87), while HIV was associated with increased odds of molecular-BV (adjusted OR = 2.76, 95% CI: 1.33 to 5.73), even when controlling for multiple relevant factors such as age, number of sexual partners, condom use, and douching. CONCLUSION: Larger and longitudinal studies are needed to further characterize molecular-BV and the vaginal microbiota in pregnant women and WWH and relate these factors to infectious, reproductive, and obstetric outcomes. In the long term, these studies may lead to novel microbiota-based therapeutics to improve women's reproductive and obstetric health.

ABSTRACT

BACKGROUND: Routinely available laboratory tests for Treponema pallidum remain suboptimal for diagnostic, prognostic, predictive, and monitoring purposes. Biomarkers with enhanced performance characteristics can improve diagnostic confidence and facilitate management. We conducted a systematic review to examine the utility of biomarkers in the diagnosis and management of syphilis. METHODS: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses to identify articles for inclusion and independently reviewed them for eligibility and study quality using a 3-stage procedure. The search, conducted by a senior library informationist, used PubMed, Embase, Cochrane Library, and Scopus and included any study published before May 2022. RESULTS: Of the 111 studies identified, 31 (27.9%) were included in our review. Most studies were cross-sectional or prospective. The data were strikingly heterogeneous examining a variety of biomarkers across different syphilis stages, using different methodologies and definitions of treatment success. Available publications chiefly focused on diagnosing various syphilis stages, neurosyphilis and congenital syphilis, serological cure, the serofast state, and reinfection. CONCLUSIONS: Despite increasing attempts to identify novel biomarkers, we found limited evidence to support the use of any biomarker in clinical decision making at this time; the syphilis biomarker literature is heterogenous and lacks measurement of clinically meaningful end points. We recommend the formation of a working group to set priorities for syphilis biomarker research and to guide future study of clinically meaningful biomarkers.

ABSTRACT

Among clinician-ordered vaginal cultures positive for Candida albicans , 30% exhibited fluconazole resistance. Resistance did not reliably predict future susceptibility. Prospective studies to verify associations with demographic and clinical factors as well as to correlate in vitro resistance with treatment response and longitudinal resistance patterns are needed.

ABSTRACT

BACKGROUND: Maternal markers of intestinal immune activation may be used to predict preterm birth (PTB) in pregnant women living with HIV. METHODS: This study used de-identified samples from the International Maternal Pediatric Adolescent AIDS Clinical Trials Group (IMPAACT) Protocol P1025 study. Singleton pregnancies with ≥3 ml plasma available and HIV viral load ≤400 copies/ml within 4 weeks of specimen collection were included. Frequency matching of PTB cases and term birth controls was performed on basis of maternal race, number of available plasma specimens, and timing of plasma sample collection in a 1:1 ratio. Plasma progesterone, 25-hydroxy vitamin D, soluble CD14, intestinal fatty acid binding protein (I-FABP), Lipopolysaccharide (LPS)-binding protein, and inflammatory cytokines (IL-1B, IFN-gamma, IL-6, TNF-alpha) were measured. Generalized mixed linear regression modeling was used to examine the association between PTB and biomarkers, adjusting for covariates and confounders. Data analyses were performed using SAS 9.4 (Cary, NC). RESULTS: We included 104 PTB compared to 104 controls. Third trimester log2 IL-1B was lower among PTB versus term birth controls by univariate analysis (-1.50 ± 2.26 vs. -.24 ± 2.69, p = .01) though this association was no longer significant by regression modeling. In an uncontrolled, exploratory sub-analysis, subjects with prior PTB had increased odds of PTB with higher I-FABP [aOR 2.72, 95% CI 1.18-6.24] and lower IFN-gamma [aOR .23, 95% CI .12-.41] after adjustment for covariates and confounders. CONCLUSIONS: Intestinal immune activation measured by soluble CD14 or intestinal fatty acid binding protein was not associated with preterm birth among pregnant women with low-level HIV viremia.

ABSTRACT

OBJECTIVES: Observational studies demonstrate an association between vaginal douching and bacterial vaginosis (BV) characterised by Gram stain. We sought to describe the effect of a douching cessation intervention on the composition and structure of the vaginal microbiota and molecular-BV, a state defined by low levels of Lactobacillus spp evaluated by molecular tools. METHODS: 33 women self-collected mid-vaginal swabs twice weekly (982 samples) during a douching observation phase (4 weeks) followed by a douching cessation phase (12 weeks) in a 2005 single crossover pilot study conducted in Baltimore, Maryland. Vaginal microbiota were characterised by 16S rRNA gene amplicon sequencing (V3-V4) and clustered into community state types (CSTs). Conditional logistic regression modelling allowed each participant to serve as their own control. Wilcoxon signed-rank tests were used to evaluate changes in microbiota between phases. Broad-range qPCR assays provided estimates of bacterial absolute abundance per swab in a subsample of seven participants before and after douching. A piecewise linear mixed effects model was used to assess rates of change in bacterial absolute abundance before and after douching. RESULTS: There was no statistically significant change in the odds of molecular-BV versus Lactobacillus-dominated CSTs comparing the douching cessation interval to douching observation (adjusted OR 1.77, 95% CI 0.89 to 3.55). Removal of L. iners-dominated CST III from the outcome did not affect the results. There were no significant changes in the relative abundance of four Lactobacillus spp and no meaningful changes in other taxa investigated. There was no significant change in bacterial absolute abundance between a participant's sample collected 3 days prior to and following douching (p=0.46). CONCLUSIONS: In this pilot study, douching cessation was not associated with major changes in vaginal microbiota. Douching cessation alone may not durably shift the vaginal microbiota and additional interventions may be needed to restore optimal vaginal microbiota among those who douche.

ABSTRACT

Urban Black men who have sex with men (MSM) bear a disproportionate burden of HIV and syphilis in the U.S. Experiences of enacted sexual minority stigma and psychological distress among these men may be associated with HIV/STI sexual and drug risk behaviors. The objective was to determine the associations between enacted sexual minority stigma, psychological distress, and sexual and drug risk behaviors. In an urban prospective cohort study, survey measures assessed past 3-month exposure to enacted sexual minority stigma, psychological distress, and sexual and drug risk behaviors. Multivariable logistic regression models were utilized for hypothesis testing. The Black MSM (N = 140) reported the following: 22.1% experiences of enacted sexual minority stigma, 39% high levels of psychological distress, 48.6% > 1 sex partner, 8.6% transactional sex, and 6% injection drug use (IDU). In models adjusted for age and education, enacted sexual minority stigma significantly increased the odds of reporting > 1 sex partner, transactional sex, and IDU. Adjusting additionally for homelessness, the association between enacted sexual minority stigma and transactional sex remained significant. Adding psychological distress to this model showed a significant association between psychological distress and transactional sex, while the association was no longer significant for transactional sex. These findings highlight some of the complex psycho-social relationships that may be associated with sexual and drug risk behaviors among Black MSM placing them at increased risk for HIV and syphilis.


RESUMEN: Hombres urbanos de raza Negra que tienen sexo con hombres (HSH) sobrellevan una carga desproporcionada de VIH y sífilis en los EE.UU. Experiencias de estigma efectivo de minoría sexual y angustia psicológica entre estos hombres pudiese ser asociado con conductas sexuales de riesgo VIH/ITS y drogas. El objetivo era determinar las asociaciones entre un estigma efectivo de minoría sexual, angustia psicológica, y comportamientos sexuales y de riesgo de drogas. En un estudio de cohortes prospectivo urbano, las medidas de la encuesta evaluada en los últimos tres meses de exposición al estigma efectivo, angustia psicológica, y sus conductas sexuales y comportamientos riesgoso de drogas. Modelos de regresión logística multivariante se utilizaron para la prueba de hipótesis. Los HSH de raza negra (N = 140) reportaron lo siguiente: 22.1% experiencias de estigma efectivo, 39% niveles altos de angustia psicológica, 48.6% y > 1 pareja sexual, 8.6% sexo transaccional, y 6% uso de drogas inyectables (UDI). En modelos ajustados a edad y educación, un estigma efectivo de minoría sexual aumentó de manera significante las probabilidades de reportar y > 1 pareja sexual, sexo transaccional, y UDI. Ajustando adicionalmente para personas sin vivienda, la asociación entre estigma efectivo de minoría sexual y sexo transaccional permaneció significante. La adición de angustia psicológica al modelo mostró una asociación significativa entre angustia psicológica y sexo transaccional, mientras que la asociación ya no era significativa para el sexo transaccional. Estos resultados destacan algunas de las complejas relaciones psicosociales que pudiesen estar asociadas con conductas sexuales y de riesgo de drogas entre HSH de raza negra, poniéndolos a mayor riesgo de contraer VIH y sífilis.

ABSTRACT

BACKGROUND: Bacterial vaginosis (BV), a condition in which vaginal Lactobacillus spp. are in low abundance, is associated with vulvovaginal symptoms, obstetric outcomes and urogenital infections. Recurrent BV is difficult to manage, and emerging data indicate a reduced risk of BV with the use of hormonal contraception (HC). Despite widespread use, little longitudinal data is available on whether, and in what timeframe, combined oral contraceptive pills (COCs) may act to affect vaginal microbiota stability and Lactobacillus dominance. METHODS: We compared the vaginal microbiota of reproductive-age cisgender women during intervals on combined estrogen and progestin COCs with non-use intervals in a 2-year observational study. Vaginal microbiota were characterized by 16S rRNA gene amplicon sequencing. FINDINGS: COC users were more likely to have Lactobacillus-dominated microbiota and more stable microbiota over time. Stability increased and then plateaued four weeks after COC initiation. The associations between COCs and Lactobacillus spp. dominance, and microbiota stability, were statistically significant for White, but not African American women; however sample size was limited for African American participants. Findings were similar for other forms of HC and when excluding samples collected during menses. INTERPRETATION: Our study provides a methodologic framework to evaluate observational longitudinal microbiota data with exposure crossovers. We found COCs are associated with vaginal microbiota stability and a Lactobacillus-dominated state. COCs appear to impact stability within a month of initiation. Our findings have clinical implications for how soon benefits can be expected in (at least White) patients initiating COCs, and support the need for larger prospective trials to verify our results in ethnically diverse populations. FUNDING: R01-AI089878.

ABSTRACT

BACKGROUND: Urban Black gay, and bisexual men (MSM) bear a disproportionate burden of HIV in the U.S. Mental health is a barrier to adherence to both antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP). The objective was to determine the association between psychological distress and ART or PrEP adherence among urban Black MSM. METHODS: Using data from a four-year prospective cohort study, adherence to ART was defined as > 95% and PrEP was defined as > 80% of doses taken in the past 30 days. Psychological distress measures included difficulty sleeping; feeling anxious; suicidality; feeling sad or depressed; feeling sick, ill, or not well in the past 3 months; high (vs. low) overall psychological distress was classified as above the median value. Associations were examined using Chi-square, Fisher's exact tests, and logistic regression. RESULTS: Among 165 Black MSM, 44.2% (73) reported high psychological distress. 65.3% (47/72) of participants living with HIV and 39.8% (37/93) of HIV negative participants were ART or PrEP adherent, respectively. Education was significantly associated with PrEP adherence (p = 0.038). Non-injection drug use in the past 3 months (p = 0.008), difficulty sleeping (p = 0.010), feeling anxious (p = 0.003), and feeling sad or depressed (p < 0.001), and overall psychological distress (p < 0.001) were significantly associated with ART adherence. High psychological distress was significantly associated with a reduced odds of ART adherence (aOR 0.23; 95% CI = 0.08-0.70) adjusting for age and non-injection drug use. CONCLUSIONS: Increased psychological distress was significantly associated with ART nonadherence and may represent an important barrier to viral suppression.

ABSTRACT

A panel of experts generated 5 "key questions" in the management of adult syphilis. A systematic literature review was conducted and tables of evidence were constructed to answer these questions. Available data suggest no clinical benefit to >1 dose of benzathine penicillin G for early syphilis in human immunodeficiency virus (HIV)-infected patients. While penicillin remains the drug of choice to treat syphilis, doxycycline to treat early and late latent syphilis is an acceptable alternate option if penicillin cannot be used. There are very limited data regarding the impact of additional antibiotic doses on serologic responses in serofast patients and no data on the impact of additional antibiotic courses on long-term clinical outcomes. In patients with isolated ocular or otic signs and symptoms, reactive syphilis serologic results, and confirmed ocular/otic abnormalities at examination, a diagnostic cerebrospinal fluid (CSF) examination is not necessary, because up to 40% and 90% of patients, respectively, would have no CSF abnormalities. Based on the results of 2 studies, repeated CSF examinations are not necessary for HIV-uninfected patients or HIV-infected patients on antiretroviral therapy who exhibit appropriate serologic and clinical responses after treatment for neurosyphilis. Finally, several important gaps were identified and should be a priority for future research.
