Syphilis positivity among men who have sex with men (MSM) with direct, indirect, and no linkage to female sex partners: Exploring the potential for sex network bridging in Baltimore City, MD.

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.

Syphilis Diagnosis After a Chlamydia, Gonorrhea, or HIV Diagnosis Among Reproductive-Aged Women in Baltimore, MD.

BACKGROUND: Syphilis incidence is increasing among reproductive-aged women, and previous sexually transmitted infections (STIs) are a risk factor for subsequent STIs. This study aimed to determine syphilis incidence after a chlamydia, gonorrhea, or HIV diagnosis, and identify characteristics associated with higher syphilis incidence rates among reproductive-aged women in 1 mid-Atlantic city. METHODS: A retrospective cohort of 85,113 chlamydia, gonorrhea, and HIV diagnoses occurring between 2009 and 2021 and among women aged 13 to 50 years was constructed using public health surveillance data. Cumulative incidence curves were estimated to examine time to early syphilis (i.e., primary, secondary, or early latent) diagnosis, and multivariable analyses determined incidence rate ratios by age (<25 vs. ≥25 years) and number of prior STI diagnoses (0 vs. ≥1) during the study period, stratified by STI. RESULTS: There were 85,113 reportable STI diagnoses and 646 syphilis diagnoses in the cohort. Approximately 1 of 150 chlamydia, 1 of 100 gonorrhea, and 1 of 50 HIV diagnoses were followed by a syphilis diagnosis within 5 years. Cumulative incidence of syphilis differed significantly by STI diagnosis ( P < 0.001). In multivariable analysis, syphilis incidence rates were higher among women diagnosed with ≥1 (vs. 0) prior STI regardless of STI type ( P < 0.05) and among women ≥25 (vs. <25) years old diagnosed with gonorrhea ( P < 0.05). CONCLUSIONS: There were significant differences in syphilis incidence by prior STI type, number of STIs, and age. Our data support targeted screening for syphilis among women with a history of STIs, parwomen with ≥1 prior STI diagnosis, and older women diagnosed with gonorrhea.

Association of Nirmatrelvir/Ritonavir Treatment and COVID-19-Neutralizing Antibody Titers in a Longitudinal Health Care Worker Cohort.

Nirmatrelvir/ritonavir (NMV/r) is used for the treatment of coronavirus disease 2019 (COVID-19) infection. However, rebound COVID-19 infections can occur after taking NMV/r. We examined neutralizing antibodies to the severe acute respiratory syndrome coronavirus 2 spike protein before and after infection in people who did and did not take NMV/r to determine if NMV/r impedes the humoral immune response.

Factors Associated With Chlamydia and Gonorrhea Treatment Completion Among Sexual Health Clinic Patients, Baltimore City, Maryland; 2018 to 2019.

BACKGROUND: Prompt and appropriate treatment of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) is critical to prevent transmission and serious sequelae. The objectives were to determine the prevalence of CT/NG treatment completion and identify demographic, behavioral, and clinical factors associated with treatment completion at sexual health clinics in Baltimore City, Maryland. METHODS: Electronic health record data from patients diagnosed with CT/NG during 2018-2019 were analyzed. Treatment completion was defined as documentation of Centers for Disease Control and Prevention-recommended treatment ≤30 days after testing. Regression was used to assess differences in treatment completion across groups; analyses were stratified by birth sex. RESULTS: Most of the 2426 male (86%) and 754 (72%) female patients diagnosed with CT/NG completed treatment in ≤30 days; 74% of male and 36% of female patients were treated same-day. Among 890 male patients not treated same-day, treatment completion was associated with other same-day antimicrobial treatments (adjusted prevalence ratio, 0.76 [95% confidence interval, 0.61-0.94]), longer test processing times (≥10 days; 0.78 [0.65-0.95]) infection at multiple anatomic sites (1.49 [1.25-1.76]), and patients with previous clinic visits (1.16 [1.03-1.31]). Among 483 female patients not treated same-day, treatment completion was associated with diagnosis year (2019 vs. 2018; 1.23 [1.05-1.43]) and residential addresses 2 to 5 miles (vs. <2 miles) from clinic (1.25 [1.02-1.53]). Demographic and behavioral characteristics were not associated with treatment completion. CONCLUSIONS: Substantial proportions of male and female sexual health clinic patients did not complete treatment. Our findings underscore the need for implementation of highly sensitive and specific point-of-care (POC) CT/NG testing to improve treatment completion in this setting.

Vaginal Candida albicans: High Frequency of in Vitro Fluconazole Resistance in a Select Population-A Brief Note.

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.

Association of healthcare worker behaviors with coronavirus disease 2019 (COVID-19) risk during four pandemic periods and characteristics associated with high-risk behaviors.

In a large healthcare worker cohort, we quantified the association between behaviors and risk of coronavirus disease 2019 (COVID-19) during different pandemic phases, adjusting for prior infection and vaccination. Individual characteristics, including personal concerns, were associated with these behaviors. Public health messaging should target high-risk populations and behaviors as the pandemic evolves.

Characteristics of Reported Gonorrhea Diagnoses During The COVID-19 Pandemic Compared With Pre-COVID-19 Pandemic, Baltimore City, Maryland.

BACKGROUND: Sexual health service disruptions due to COVID-19 mitigation measures may have decreased gonorrhea screening and biased case-ascertainment toward symptomatic individuals. We assessed changes in reported symptoms and other characteristics among reported gonorrhea cases during pandemic versus prepandemic periods in 1 city with persistent gonorrhea transmission. METHODS: Enhanced surveillance data collected on a random sample of gonorrhea cases reported to the Baltimore City Health Department between March 2018 and September 2021 was used. Logistic regression assessed differences in case characteristics by diagnosis period (during pandemic: March 2020-September 2021; prepandemic: March 2018-September 2019). RESULTS: Analyses included 2750 (1090 during pandemic, 1660 prepandemic) gonorrhea cases, representing 11,904 reported cases. During pandemic versus prepandemic, proportionally fewer cases were reported by sexual health clinics (8.8% vs 23.2%), and more frequently reported by emergency departments/urgent care centers (23.3% vs 11.9%). Adjusting for diagnosing provider, fewer cases who were men with urethral infections (adjusted odds ratio [aOR], 0.65; 95% confidence interval [CI], 0.55-0.77), aged <18 years (aOR, 0.64; 95% CI, 0.47-0.89), and women (aOR, 0.84; 95% CI, 0.71-0.99) were reported, and cases with insurance (aOR, 1.85; 95% CI, 1.40-2.45), living with human immunodeficiency virus (aOR, 1.43; 95% CI, 1.12-1.83), or recent (≤12 months) gonorrhea history (aOR, 1.25; 95% CI, 1.02-1.53) were more frequently reported during pandemic versus prepandemic. Reported symptoms and same-day/empiric treatment did not differ across periods. CONCLUSIONS: We observed no changes in reported symptoms among cases diagnosed during pandemic versus prepandemic. Increased frequency of reported diagnoses who were insured, living with human immunodeficiency virus, or with recent gonorrhea history are suggestive of differences in care access and care-seeking behaviors among populations with high gonorrhea transmission during the pandemic.

Sexually Transmitted Infections Among Men and Transgender Women Using HIV Pre-exposure Prophylaxis in a Large Integrated Health System-A Cohort Study.

BACKGROUND: Sexually transmitted infections (STIs) are common in people using pre-exposure prophylaxis (PrEP). We examined risk and factors associated with STIs in a cohort of PrEP users in an integrated health system in the United States. SETTING: The Kaiser Permanente Southern California is a large integrated health system that provides comprehensive medical services to approximately 4.7 million demographically diverse members. METHODS: We identified men and transgender women initiating PrEP between January 1, 2014, and June 1, 2018, and followed through December 31, 2018. Demographic and clinical factors potentially associated with the risk of bacterial STIs during PrEP use were evaluated using Poisson regression models. RESULTS: Among 5042 individuals tested for STIs with 7198 person-years of follow-up, 1709 (33.9%) had at least one new STI. The estimated incidence of STIs was 48.3 per 100 person-years, and the most common STI was rectal chlamydia. Most repeat STIs (61.4%) occurred <180 days apart. In a multivariable analysis, an history of STIs in the prior 6 months through 7 days after the PrEP initiation was the most prominent risk factor of STIs during PrEP use (adjusted risk ratio: 1.78, 95% confidence intervals: 1.65 to 1.93). Other risk factors included younger age (<35 years), being Hispanic, and having a history of alcohol use disorder or drug use disorder. CONCLUSIONS: Quarterly STI testing and targeted intervention to mitigate STI risk are warranted for young and racial minority PrEP users, particularly for those with prior history of STIs and substance use disorders.

Sexually Transmitted Infection Transmission Dynamics During the Coronavirus Disease 2019 (COVID-19) Pandemic Among Urban Gay, Bisexual, and Other Men Who Have Sex With Men.

BACKGROUND: The impact of coronavirus disease 2019 (COVID-19) mitigation measures on sexually transmitted infection (STI) transmission and racial disparities remains unknown. Our objectives were to compare sex and drug risk behaviors, access to sexual health services, and STI positivity overall and by race during the COVID-19 pandemic compared with pre-pandemic among urban sexual minority men (MSM). METHODS: Sexually active MSM aged 18-45 years were administered a behavioral survey and STI testing every 3-months. Participants who completed at least 1 during-pandemic (April 2020-December 2020) and 1 pre-pandemic study visit (before 13 March 2020) that occurred less than 6 months apart were included. Regression models were used to compare during- and pre-pandemic visit outcomes. RESULTS: Overall, among 231 MSM, reports of more than 3 sex partners declined(pandemic-1: adjusted prevalence ratio 0.68; 95% confidence interval: .54-.86; pandemic-2: 0.65, .51-.84; pandemic-3: 0.57, .43-.75), substance use decreased (pandemic-1: 0.75, .61-.75; pandemic-2: 0.62, .50-.78; pandemic-3: 0.61, .47-.80), and human immunodeficiency virus/preexposure prophylaxis care engagement (pandemic-1: 1.20, 1.07-1.34; pandemic-2: 1.24, 1.11-1.39; pandemic-3: 1.30, 1.16-1.47) increased. STI testing decreased (pandemic-1: 0.68, .57-.81; pandemic-2: 0.78, .67-.92), then rebounded (pandemic-3: 1.01, .87-1.18). Nei-ther Chlamydia (pandemic-2: 1.62, .75-3.46; pandemic-3: 1.13, .24-1.27) nor gonorrhea (pandemic-2: 0.87, .46 1.62; pandemic-3: 0.56, .24-1.27) positivity significantly changed during vs pre-pandemic. Trends were mostly similar among Black vs. non-Black MSM. CONCLUSIONS: We observed sustained decreases in STI risk behaviors but minimal change in STI positivity during compared with pre-pandemic. Our findings underscore the need for novel STI prevention strategies that can be delivered without in-person interactions.

HIV Transmission Potential and Sex Partner Concurrency: Evidence for Racial Disparities in HIV Risk Among Gay and Bisexual Men (MSM).

We determined whether racial disparities in HIV infection among gay and bisexual men (MSM) may be partially explained by racial differences in the HIV transmission potential (i.e. mixing of people living with HIV and people not living with HIV or of unknown HIV serostatus) and density (i.e. sex partner concurrency) of sexual networks. Data included a behavioral survey, testing for HIV, and an egocentric sexual network survey. Mixed effects logistic regressions were used for hypothesis testing. Black (vs. non-Black) MSM were more likely to not know their partner's HIV serostatus (21.8% vs. 9.6%). Similar proportions reported sex partner concurrency (67.1% vs. 68.0%). In adjusted analyses, among Black MSM, sex partner concurrency significantly increased the odds of an HIV transmission potential partnership (TPP), and this association was not significant among non-Black indexes. The association between an HIV TPP and sex partner concurrency may help explain persistent racial disparities in HIV prevalence.

RESUMEN: Determinamos si las disparidades raciales en infecciones del VIH entre hombres homosexuales y bisexuales (hombres que tienen sexo con hombres) puede ser parcialmente explicado por diferencias raciales en el potencial de transmisión del VIH (es decir, mezcla de personas viviendo con VIH y personas que no viven con VIH o cuyo estado serológico del VIH es desconocido) y densidad (es decir, concurrencia de pareja sexual) de redes sexuales. Los datos incluyeron una encuesta de comportamiento, pruebas para el VIH y una encuesta de redes sexuales egocéntrica. Regresiones logísticas de efectos mixtos fueron usados para la prueba de hipótesis. HSH negros (vs. HSH no-negros) eran más propensos a no saber el estado serológico del VIH de su pareja (21.8% vs. 9.6%). Proporciones similares reportaron concurrencia de pareja sexual (67.1% vs. 68.0%). En análisis ajustados, entre HSH negros, la concurrencia de pareja sexual aumentó significativamente las probabilidades de una asociación potencial de transmisión del VIH (TPP por sus siglas en inglés), y esta asociación no fue significativa entre índices de no-negros. La asociación entre una TPP VIH y concurrencia de pareja sexual puede ayudar a explicar disparidades raciales persistentes en la prevalencia del VIH.

Methamphetamine Use, Syphilis, and Specific Online Sex Partner Meeting Venues Are Associated With HIV Status Among Urban Black Gay and Bisexual Men Who Have Sex Men.

BACKGROUND: In the context of increasing syphilis rates, particularly among Black men who have sex men (MSM), the objectives were to determine the associations between methamphetamine (meth) use and syphilis and HIV positivity, and to identify sex partner meeting venues as potential intervention access points among Black MSM in a mid-Atlantic US city. METHODS: This study is an ongoing longitudinal cohort study. Participants were recruited from clinical and nonclinical settings and included sexually active MSM aged 18 to 45 years. The baseline visit included a behavioral survey and testing for syphilis, HIV, gonorrhea, and chlamydia. Logistic regression analyses were used for hypothesis testing. RESULTS: Among 359 MSM completing baseline, 74.4% (268) Black MSM were included; 31% (84) were aged 24 to 29 years, 43.7% (117) reported unprotected anal intercourse at last sex, and 15.3% (41) reported meth use in the past 3 months. Sixteen percent (43) had syphilis, 46.6% (125) were living with HIV, and 19.0% (51) had gonorrhea and/or chlamydia. Meth use was associated with sexual and drug risk behaviors and HIV, but not syphilis. In adjusted analyses, meth use increased the odds of HIV positivity by 6.43 (95% confidence interval, 2.30-17.98) and syphilis positivity by 2.57 (95% confidence interval, 1.23-5.37). Four online sex partner meeting venues were associated with meth use and HIV, whereas syphilis was associated with one. CONCLUSIONS: Among Black MSM, meth use and syphilis positivity were associated with more than 6-fold and almost 3-fold increased adjusted odds of HIV positivity, respectively. Four specific sex partner meeting venues may be important access points for HIV/sexually transmitted infection and substance use prevention.

Reaching Those Most at Risk for HIV Acquisition: Evaluating Racial/Ethnic Disparities in the Preexposure Prophylaxis Care Continuum in Baltimore City, Maryland.

BACKGROUND: Reducing HIV incidence requires addressing persistent racial/ethnic disparities in HIV burden. Our goal was to evaluate preexposure prophylaxis (PrEP) delivery, overall and relative to community need, among 7 clinical sites participating in a health department-led demonstration project to increase PrEP in Baltimore city, MD. METHODS: PrEP care continuum stages (screened, indicated, referred, linked, evaluated, prescribed) were examined among HIV-negative individuals receiving services at participating sites between September 30, 2015 and September 29, 2019. Community need was defined using information on new HIV diagnoses (2016-2018). Differences in care continuum progression by demographics/priority population and comparison of demographic compositions between care continuum stages and new HIV diagnoses were examined using modified Poisson regression and χ2 tests, respectively. RESULTS: Among 25,886 PrEP-screened individuals, the majority were non-Hispanic (NH) black (81.1%, n = 20,998), cisgender male (61.1%, n = 15,825), and heterosexual (86.7%, n = 22,452). Overall, 31.1% (n = 8063) were PrEP-indicated; among whom, 56.8% (n = 4578), 15.6% (n = 1250), 10.8% (n = 868), and 9.0% (n = 722) were PrEP-referred, linked, evaluated, and prescribed, respectively. Among 2870 men who have sex with men (MSM), 18.7% (n = 538) were PrEP-prescribed. Across all groups, the highest attrition was between PrEP-referred and PrEP-linked. NH-black race (vs. NH-white) was independently associated with lower likelihood of PrEP prescription (aPR, 0.89; 95% confidence interval, 0.81 to 0.98 controlling for age/gender). Relative to the demographic composition of new HIV diagnoses, fewer NH-blacks (80.2% vs. 54.3%) and more NH-whites (10.7% vs. 30.3%) and MSM were PrEP prescribed (55.2% vs. 74.5%). CONCLUSIONS: This project showed promise delivering PrEP referrals and prescriptions overall and to MSM. Substantial improvement is needed to improve linkage overall and to decrease disparities in PrEP prescriptions among NH-blacks. Future work should focus on addressing service gaps that hinder PrEP utilization.

Referral Linkage to Preexposure Prophylaxis Care and Persistence on Preexposure Prophylaxis in an Integrated Health Care System.

BACKGROUND: Successful linkage to preexposure prophylaxis (PrEP) and retention in care are important for HIV prevention. We examined gaps in PrEP care following referral and factors associated with PrEP linkage and persistence in an integrated health care system in the United States. METHODS: We identified individuals referred for PrEP from 2014 to 2017 at the Kaiser Permanente Southern California using electronic health records and assessed linkage to care, PrEP prescription orders and fills, and PrEP persistence (medication possession ratio ≥80%) in the year after the first fill. We evaluated demographic and clinical factors potentially associated with PrEP linkage and persistence using a series of multivariable modified Poisson regression models. RESULTS: Of 2995 referred individuals, 74.9% were linked to PrEP care. Nearly all those linked to care were prescribed PrEP and filled a prescription, but only 47.4% of those who filled a prescription were persistent on PrEP. Individuals aged <25 years (vs ≥25 years), female subjects (vs males), and individuals with high-deductible insurance (vs no high deductible) were less likely to be linked to care. Individuals aged <25 years and Hispanics (vs non-Hispanic whites) were less likely to be persistent. Those with alcohol use disorder were more likely to be linked to PrEP care but less likely to be persistent. New HIV diagnoses occurred in 38 individuals, and only 1 had PrEP in possession at diagnosis. CONCLUSIONS: We observed PrEP care gaps and disparities among individuals referred for PrEP. Patient-centered interventions are needed in primary care to address barriers to successful PrEP linkage and persistence.

HIV Screening Among Gonorrhea-Diagnosed Individuals; Baltimore, Maryland; April 2015 to April 2019.

BACKGROUND: Individuals diagnosed with gonorrhea are at elevated risk for HIV. Per US Centers for Disease Control and Prevention guideline, individuals being evaluated for gonorrhea should be screened for HIV concurrently. There is limited information on HIV screening among gonorrhea-diagnosed individuals across different health care settings. Our objective was to identify potential gaps in HIV screening among gonorrhea-diagnosed individuals in Baltimore City, Maryland. METHODS: We used Sexually Transmitted Disease Surveillance Network project data collected on a random sample of all gonorrhea diagnoses reported to the health department between April 2015 and April 2019. Individuals with known HIV diagnoses were excluded. HIV screening was confirmed through surveys administered to the gonorrhea-diagnosing provider. HIV screening across groups was assessed using Poisson regression models with robust SEs. We examined those with and without recent (≤12 months) sexually transmitted infection (STI) history separately. RESULTS: Among 2830 gonorrhea-diagnosed individuals with completed Sexually Transmitted Disease Surveillance Network provider surveys, less than half (35.2% with and 44.8% without recent STI history) received concurrent HIV screening. HIV screening was 73% less prevalent among those diagnosed in emergency departments/urgent care centers/hospitals versus sexual health clinics (with and without recent STI history: adjusted prevalence ratio, 0.27 [95% confidence interval, 0.19-0.39]; adjusted prevalence ratio, 0.27 [0.23-0.33]), controlling for diagnosis year, sex, race/ethnicity, age, infection site, and insurance. CONCLUSIONS: Our findings suggest a considerable gap in HIV screening among individuals at elevated risk for HIV acquisition in Baltimore City, particularly among those diagnosed in emergency departments/urgent care centers/hospital settings. Future work should focus on identifying provider-level barriers to concurrent HIV/STI screening to inform provider education programs.

Identifying Community-Informed Language to Promote HIV Pre-exposure Prophylaxis (PrEP) in Black LGBTQ Communities in Baltimore.

LGBTQ populations, particularly Black men who have sex with men and transgender women, experience significant HIV disparities; public health messages may inadvertently stigmatize LGBTQ populations. We sought to use qualitative methods to inform a PrEP campaign. Unstructured focus groups were conducted among predominantly Black LGBTQ persons recruited through social media and events. Discussions were audio-recorded, transcribed, and analyzed in NVivo using categorical analysis. Eighty individuals participated in 13 focus groups; 80% (64) identified as sexual or gender minorities. Eighty-eight percent (70) identified as Black/African American. Four themes emerged: (1) culturally competent, community-informed, locally relevant messaging, (2) avoiding stigmatizing language or images, (3) inaccessibility of clinical language, and (4) using identity labels representing local communities and their diversity. Findings suggest PrEP campaigns need to be developed through community-informed processes to engage and avoid stigmatizing priority populations. Ongoing partnerships between public health and LGBTQ communities can facilitate development of campaigns with engaging, acceptable language.

The Association Between Social Support, Violence, and Social Service Needs Among a Select Sample of Urban Adults in Baltimore City.

Experiencing violence has been associated with negative health outcomes. The objectives of this study were to determine whether experiencing violence is associated increased support service needs and suboptimal general health indicators. In addition, we explore the relationship between these and perceived social support among a select sample of urban predominantly male adults in Baltimore City. A cross-sectional survey was conducted among 187 adults being seen in one of seven urban partner agencies participating in a parent HIV prevention and treatment demonstration project. Associations were examined using a multivariable logistic regression model, adjusting for the clinic site at which the client was being seen as well as age and gender identity. There was a significant amount of violence experienced by this population; 131 (72%) reported having seen someone be physically assaulted, and 89 (49%) had been physically assaulted without a weapon. Direct victimization from violence was associated with a threefold increased odds of needing housing and mental health/substance use services. Exposure to violence was associated with a threefold increase in needing housing and mental health/substance use services, and with sub-optimal health status. Perceived social support was associated with 30% decreased reports of experiencing violence. In conclusion, our select sample of urban adults report having experienced high rates of violence, and this is associated with increased support service needs as well as suboptimal perceived health status. Incorporating care for the effects of experiencing violence as well as social service needs are important in optimizing the health of urban populations.

Gonorrhoea and chlamydia diagnosis as an entry point for HIV pre-exposure prophylaxis: a modelling study.

OBJECTIVES: Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) increase the risk of HIV transmission among men who have sex with men (MSM). Diagnosis of NG/CT may provide an efficient entry point for prevention of HIV through the delivery of pre-exposure prophylaxis (PrEP); however, the additional population-level impact of targeting PrEP to MSM diagnosed with NG/CT is unknown. DESIGN: An agent-based simulation model of NG/CT and HIV cocirculation among MSM calibrated against census data, disease surveillance reports and the US National HIV Behavioral Surveillance study. SETTING: Baltimore City, Maryland, USA. INTERVENTIONS: PrEP implementation was modelled under three alternative scenarios: (1) PrEP delivery at NG/CT diagnosis (targeted delivery), (2) PrEP evaluation at NG/CT screening/testing and (3) PrEP evaluation in the general community (untargeted). MAIN OUTCOME: The projected incidence of HIV after 20 years of PrEP delivery under two alternatives: when equal numbers of MSM are (1) screened for PrEP or (2) receive PrEP in each year. RESULTS: Assuming 60% uptake and 60% adherence, targeting PrEP to MSM diagnosed with NG/CT could reduce HIV incidence among MSM in Baltimore City by 12.4% (95% uncertainty range (UR) 10.3% to 14.4%) in 20 years, relative to no PrEP. Expanding the coverage of NG/CT screening (such that individuals experience a 50% annual probability of NG/CT screening and evaluation for PrEP on NG/CT diagnosis) can further increase the impact of targeted PrEP to generate a 22.0% (95% UR 20.1% to 23.9%) reduction in HIV incidence within 20 years. When compared with alternative implementation scenarios, PrEP evaluation at NG/CT diagnosis increased impact of PrEP on HIV incidence by 1.5(95% UR 1.1 to 1.9) times relative to a scenario in which PrEP evaluation happened at the time of NG/CT screening/testing and by 1.6 (95% UR 1.2 to 2.2) times relative to evaluating random MSM from the community. CONCLUSIONS: Targeting MSM infected with NG/CT increases the efficiency and effectiveness of PrEP delivery. If high levels of sexually transmitted infection screening can be achieved at the community level, NG/CT diagnosis may be a highly effective entry point for PrEP initialisation.

Human Immunodeficiency Virus Diagnosis After a Syphilis, Gonorrhea, or Repeat Diagnosis Among Males Including non-Men Who Have Sex With Men: What Is the Incidence?

BACKGROUND: The release of the first drug for human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) in 2012 marked the beginning of a new era of HIV prevention. Although PrEP is highly efficacious, identifying and ultimately increasing uptake among the highest risk male subgroups remains a challenge. METHODS: Public health surveillance data from 2009 to 2016 was used to evaluate the risk of an HIV diagnosis after a syphilis (ie, primary, secondary, or early latent), gonorrhea, and repeat diagnoses among urban males, including men who have sex with men (MSM) and non-MSM in Baltimore City. RESULTS: Of the 1531 males with 898 syphilis diagnoses and 1243 gonorrhea diagnoses, 6.8% (n = 104) were subsequently diagnosed with HIV. Within 2 years, 1 in 10 syphilis or gonorrhea diagnoses were followed by an HIV diagnosis among MSM, and 1 in 50 syphilis or gonorrhea diagnoses were followed by an HIV diagnosis among non-MSM. Among non-MSM with gonorrhea, the rate of HIV incidence was 5.36 (95% confidence interval, 2.37-12.14) times higher in those with (vs. without) a subsequent syphilis diagnosis or gonorrhea diagnosis. CONCLUSIONS: Local health care providers should offer PrEP to MSM diagnosed with syphilis or gonorrhea and to non-MSM with a previous gonorrhea diagnosis at time of a syphilis or gonorrhea diagnosis. The high proportion and short time to an HIV diagnosis among MSM after a syphilis or gonorrhea diagnosis suggest immediate PrEP initiation.

Chlamydia, Gonorrhea, and Human Immunodeficiency Virus Infection Among Transgender Women and Transgender Men Attending Clinics that Provide Sexually Transmitted Disease Services in Six US Cities: Results From the Sexually Transmitted Disease Surveillance Network.

BACKGROUND: Transgender women and transgender men are disproportionately affected by human immunodeficiency virus (HIV) infection and may be vulnerable to other sexually transmitted diseases (STDs), but the lack of surveillance data inclusive of gender identity hinders prevention and intervention strategies. METHODS: We analyzed data from 506 transgender women (1045 total visits) and 120 transgender men (209 total visits) who attended 26 publicly funded clinics that provide STD services in 6 US cities during a 3.5-year observation period. We used clinical and laboratory data to examine the proportion of transgender women and transgender men who tested positive for urogenital and extragenital chlamydial or gonococcal infections and who self-reported or tested positive for HIV infection during the observation period. RESULTS: Of the transgender women tested, 13.1% tested positive for chlamydia and 12.6% tested positive for gonorrhea at 1 or more anatomic sites, and 14.2% were HIV-infected. Of transgender men tested, 7.7% and 10.5% tested positive for chlamydia and gonorrhea at 1 or more anatomic sites, and 8.3% were HIV-infected. Most transgender women (86.0% and 80.9%, respectively) and more than a quarter of transgender men (28.6% and 28.6%, respectively) with an extragenital chlamydial or gonococcal infection had a negative urogenital test at the same visit. CONCLUSIONS: Publicly funded clinics providing STD services are likely an important source of STD care for transgender persons. More data are needed to understand the most effective screening approaches for urogenital, rectal, and pharyngeal Chlamydia trachomatis and Neisseria gonorrhoeae infections in transgender populations.

Three Years Post-Affordable Care Act Sexually Transmitted Disease Clinics Remain Critical Among Vulnerable Populations.

INTRODUCTION: The purpose of the study is to examine whether demand for publicly funded sexually transmitted disease clinics changed after Affordable Care Act implementation. METHODS: The percentages of total incident sexually transmitted infections in Baltimore City that occurred at publicly funded sexually transmitted disease clinics were compared between the 3 years prior to and following the 2014 Medicaid and private insurance expansions. Risk factors associated with diagnosis at sexually transmitted disease clinics were identified using log binomial regression. Statistical analyses were conducted in May 2017. RESULTS: Post-Affordable Care Act, the relative proportion of total sexually transmitted infection diagnoses increased among private and hospital-affiliated clinics, remained unchanged at sexually transmitted disease clinics, and decreased at federally qualified health centers and other publicly funded programs (p<0.001). Multivariable analysis controlling for age, sex, race, and ethnicity showed an overall decline in the risk of diagnosis at sexually transmitted disease clinics post-Affordable Care Act compared with prior (adjusted relative risk=0.92, 95% CI=0.89, 0.96), but the risk among black and Latino men aged <25 years persisted (relative risk=1.03, 95% CI=0.96, 1.10). CONCLUSIONS: The Affordable Care Act increased access to traditional health care, reducing burden on publicly funded programs. However, demand for sexually transmitted disease clinics remains substantial among priority patients. In the healthcare reform era, sexually transmitted disease clinic funding remains critical.
