STD screening of HIV-infected MSM in HIV clinics

The Effect of Using a Standardized Questionnaire on Sexual History Documentation and Testing to Diagnose Gonorrhea and Chlamydia Among Men Who Have Sex With Men With Human Immunodeficiency Virus

BACKGROUND

Most Neisseria gonorrhea (GC) and Chlamydia trachomatis (CT) infections in men who have sex with men (MSM) are diagnosed at extragenital sites. However, testing at these sites is often lacking. The purpose of this study was to determine if a standardized questionnaire administered by physicians and clinical assistants improves documentation of sex activity and increases extragenital testing and diagnoses of GC and CT among MSM.

METHODS

A standardized sexual history questionnaire was implemented on 11/1/2022. Electronic medical records of 664 MSM with human immunodeficiency virus, including 1064 encounters, were reviewed to compare preimplementation and postimplementation sexual history documentation, adequacy of documentation, extragenital GC and CT testing, and GC and CT diagnoses. Analysis included χ 2 and exact tests and logistic regression adjusting for physician cluster effects.

RESULTS

The standardized questionnaire was used by 53.7% of physicians and 85.9% of coordinators. Documentation of whether sexual activity occurred increased from 79.3% (95% confidence interval [CI], 0.758-0.828) in the preintervention pre-COVID-19 period to 95.2% (95% CI, 0.925-0.970) in the postintervention period with an adjusted odds ratio of 4.7 (95% CI, 2.7-8.8). Specific questions about anal and oral sex increased from 42.0% to 88.1% ( P < 0.001) and 23.7% to 88.7% ( P < 0.001), respectively. Anal and pharyngeal testing increased from 14.4% to 20.2% ( P = 0.040) and 17.2% to 23.3% ( P = 0.045), respectively.

CONCLUSIONS

This study demonstrates that using a standardized questionnaire during clinical encounters can improve documentation of sexual activity and testing for GC and CT at extragenital sites.

Acceptability of Multilevel Sexual Health Interventions and Sexually Transmitted Infection Screening and Testing Among Persons With HIV Across Three Clinical Sites in Florida

INTRODUCTION

The US state of Florida has the third highest rate of HIV and high rates of sexually transmitted infections (STIs) indicating critical HIV and STI prevention needs remain unmet. To address gaps in the STI care continuum in people with HIV (PWH), evidence-based interventions were implemented across 3 Ryan White HIV/AIDS Program (RWHAP)-funded clinics in Florida between August 2020 and August 2021. Interventions included comprehensive sexual health history (SHH) taking using audio computer-assisted self-interview (ACASI) software, self-collected extragenital gonorrhea and chlamydia testing, and the introduction of a lesbian, gay, bisexual, transgender, and queer (LGBTQ+) welcoming environment.

METHODS

We (1) assessed the acceptability of these interventions and examined if acceptability differed among youth and sexual, racial, and ethnic minorities; (2) determined the proportion of appropriate STI testing completed based on the SHH assessment; (3) examined whether STI at-risk individuals underwent STI screening 3-6 months after initial evaluation; and (4) determined the proportion of positive STI test results among priority intervention groups in Florida.

RESULTS

Acceptability of all interventions was high. Youth, lesbian, gay, and bisexual, and Hispanic individuals were significantly more likely to notice and like LGTBQ+ welcoming measures. The proportion of recommended tests completed was high, although only a subset of at-risk individuals completed rescreening. About 11.9% of rectal samples were positive for chlamydia, and 6.5% of pharyngeal samples were positive for gonorrhea.

CONCLUSIONS

Our study highlights the importance of incorporating comprehensive sexual health care protocols, including extragenital STI testing, into the overall care of PWH.

STI/HIV testing, STIs, and HIV PrEP use among men who have sex with men (MSM) and men who have sex with men and women (MSMW) in United States, 2019-2022

BACKGROUND

Routine sexually transmitted infection and human immunodeficiency virus (STI/HIV) testing and HIV pre-exposure prophylaxis (PrEP) use are recommended for men who have sex with men (MSM) at increased risk of HIV.

METHODS

Using Healthverity, a large administrative dataset in the United States, we assessed STI/HIV testing, chlamydia and gonorrhea positivity by specimen type, and HIV PrEP use among MSM and men who have sex with men and women (MSMW) at their first visits (index date) for those at increased risk of HIV and STIs from 2019 through 2022.

RESULTS

Among 81,716 MSM and MSMW aged 15-64 years at their index date visit, STI testing rates were 57.9% for chlamydia, 58.1% for gonorrhea, and 52.2% for syphilis testing, respectively; 55.5%, 30.9%, and 18.1% had HIV testing, HIV PrEP use, and PrEP initiation, respectively, among the patients who did not have HIV. Of patients with chlamydia and gonorrhea testing, 48% were tested from the genital site only and 25% from three anatomic sites (rectal, pharyngeal, and urogenital). Chlamydia and gonorrhea positivity was 9.8% for chlamydia rectal infection, 7.3% for gonorrhea rectal infection, and 5.3% for gonorrhea pharyngeal infection.

CONCLUSION

Our results present current medical services provided during initial clinic visits for MSM and MSMW in private outpatient settings. Our study suggests that the assessment of STI/HIV testing is periodically needed due to the high prevalence of infection, and efforts to promote HIV PrEP for MSM and MSMW in private settings are urgently needed.

Perceptions and Experiences of Returning Self-collected Specimens for HIV, Bacterial STI and Potential PrEP Adherence Testing among Sexual Minority Men in the United States

Few studies among gay, bisexual and other men who have sex with men (GBMSM) have examined facilitators and barriers to self-collecting specimens for extragenital STI screening, and none have evaluated attitudes towards self-collecting hair samples that can be utilized for PrEP drug level testing to assess adherence. To address this gap, we interviewed 25 sexually active GBMSM who were offered a choice to self-collect and return finger-stick blood samples (for actual HIV testing), pharyngeal swabs, rectal swabs and urine specimens (for actual gonorrhea and chlamydia testing), and hair samples (to visually determine their adequacy for PrEP drug level testing): 11 who returned all, 4 who returned some, and 10 who did not return any. Participants found self-collecting finger-stick blood samples and rectal swabs more challenging than other specimens. Frequently discussed facilitators of return included an opportunity to confirm one's HIV or STI status, limited access to a healthcare provider and a desire to advance research focusing on home-based testing. Commonly cited barriers to return included low self-efficacy pertaining to self-collection and apprehension around the possibility of delay or loss of specimens during transit. Offering additional support such as real-time video conferencing may prove helpful in future field-based research with GBMSM.

A Missed Opportunity: Extragenital Screening for Gonorrhea and Chlamydia Sexually Transmitted Infections in People with HIV in a Southeastern Ryan White HIV/AIDS Program Clinic Setting

Background

Guidelines recommend annual screening for gonorrhea/chlamydia in sexually active people with HIV at multiple sites (urogenital, oropharyngeal, rectal). In the first year of multisite screening at our Ryan White HIV/AIDS Program clinic, we studied (1) sexual history documentation rate, (2) sexually transmitted infection (STI) screening rate, (3) characteristics associated with STIs, (4) the percentage of extragenital STIs that would have been missed without multisite screening.

Methods

Participants were ≥14 years old with ≥1 in-person medical visit at our clinic in 2019. Descriptive analyses were performed, and adjusting for number of sites tested, a log-binomial model was used to estimate the association between characteristics and STI diagnosis in men.

Results

In this cohort (n = 857), 21% had no sexual history recorded. Almost all STI diagnoses were among males (99.3%). 68% (253/375) received appropriate urogenital testing, 63% (85/134) received appropriate oropharyngeal testing, and 69% (72/105) received appropriate rectal testing. In male participants with ≥1 STI test (n = 347), Hispanic ethnicity and detectable HIV viral load were associated with an STI diagnosis. Of those diagnosed with an STI who had multisite testing, 96% (n = 25/26) were positive only at an extragenital site.

Conclusions

Screening rates were similar across all anatomical sites indicating no obvious bias against extragenital testing. In males, STIs were more frequently diagnosed in people who identify as Hispanic and those with detectable viral loads which may indicate more condomless sex in these populations. Based on infections detected exclusively at extragenital sites, our clinic likely underdiagnosed STIs prior to implementation of multisite screening.

Incidence, Reinfection, and Discrepancy Between Sexual Practice and Anatomic Site Positivity of Sexually Transmitted Infections in Youth With HIV

BACKGROUND

This study aimed to determine the overall incidence and reinfection rates of sexually transmitted infections (STIs) and the discrepancy between self-reported exposure history and anatomic site positivity of STIs among adolescents and young adults (AYAs) with HIV in Atlanta, GA.

METHODS

Retrospective chart review was conducted on all patients 13-24 years of age at the Grady Ponce and Family Youth Clinic from January 1, 2009 to December 31, 2018. Data were collected on patient demographics, self-reported sexual history and STI events. First STI incidence and incidence of reinfections were calculated by dividing new cases over corresponding person follow-up time.

RESULTS

A total of 626 sexually active AYAs with HIV were included in analysis. The mean age at first observation was 18.9 (SD: ±2.8) years; 72% were male, 92% were Black and 80% were horizontally infected. The cumulative first STI incidence rate was 45.49 cases per 100 person-years, and the recurrent STI incidence rate was 119.86 cases per 100 person-years. Among all Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) cases, the most common site of infection was the rectum (48.6% and 49.6%, respectively). Disagreement between exposure history and presence of GC or CT infection was statistically significant for nearly all anatomic sites and types of intercourse.

CONCLUSIONS

AYAs with HIV in Atlanta have disproportionately high first and recurrent incidence rates of STIs, with many patients not reporting exposure at their site of infection. There is considerable need to increase screening for STIs, including routine extragenital testing for GC and CT, among AYAs with HIV regardless of self-reported exposure history.

High levels of undiagnosed rectal STIs suggest that screening remains inadequate among Black gay, bisexual and other men who have sex with men

OBJECTIVE

To better understand rectal STI screening practices for Black gay, bisexual and other men who have sex with men (BGBMSM).

FINDINGS

Although 15% of BGBMSM lab tested positive for a rectal STI, the majority of these (94%) were asymptomatic. Though all participants reported their status as HIV negative/unknown, 31 of 331 (9.4%) tested positive on HIV rapid tests. Neither condomless anal intercourse nor the number of male sex partners was associated with rectal STI or HIV diagnosis, although rectal STI diagnosis was positively related to testing HIV positive.

CONCLUSIONS

Findings suggest that substantial numbers of BGBMSM have asymptomatic STIs but are not tested-an outcome that is likely a strong driver of onward HIV acquisition. Therefore, we must address the asymptomatic STI epidemic among GBMSM in order to reduce HIV transmission, as well as temper STI transmission, among this key population.

Attitudes and Preferences Regarding Non-Clinic-Based Self-Collection for Sexually Transmitted Infection Testing Among Clinic Attendees in British Columbia, Canada

BACKGROUND

Sexually transmitted infections (STIs) are a global epidemic; although screening programs reduce transmission, barriers, including access and stigma, hinder success. The World Health Organization highlights the ability to maintain health without the direct support of a health care provider as one form of self-care, which can be applied to STI testing. Self-care through non-clinic-based self-collection for STI testing can address barriers while providing comprehensive care. Before implementation of innovative changes to screening approaches, it is important to understand if communities who rely on in-person care will self-collect outside of the clinic setting. This study investigated willingness to use non-clinic-based self-collection for STI testing among STI clinic attendees in British Columbia, Canada.

METHODS

Participants (n = 446) were recruited from STI clinics offering clinic-based self-collection for STI testing and completed a survey assessing self-care attitudes, including willingness to self-collect urine samples, throat swabs, and anogenital swabs outside of the clinic setting. Descriptive statistics, bivariable analyses, and multivariable models were conducted to investigate willingness to use non-clinic-based STI self-collection methods and associated correlates.

RESULTS

This population reported high willingness to use non-clinic-based self-collection methods for STI testing (urine samples, 73%; throat swabs, 67%; anogenital swabs, 65%). Those aged 35 to 54 years compared with 15 to 34 years were more likely to be willing (adjusted odds ratio, 1.87; 95% confidence interval, 1.03-3.50); those identifying as straight/mostly straight compared with gay/lesbian were less likely to be willing (adjusted odds ratio, 0.39; 95% confidence interval, 0.23-0.65).

CONCLUSIONS

Non-clinic-based self-collection for STI testing can address barriers to testing while maintaining quality care. Those currently receiving in-person care find these methods highly acceptable. These findings reinforce that self-collection for STI testing used in British Columbia clinics is acceptable to clients and may be extended to collection performed outside of the clinical setting.

Molecular screening in a longitudinal cohort of young men who have sex with men and young transgender women: associations with focus on the emerging sexually transmitted pathogen Mycoplasma genitalium

OBJECTIVES

This investigation sought to characterise risk factors associated with acquisition of traditional and emerging agents of sexually transmitted infection (STI) in a cohort of young men who have sex with men and transgender women.

METHODS

917 participants provided urine and rectal swab submissions assessed by transcription-mediated amplification (TMA)-based assays for Chlamydia trachomatis and Neisseria gonorrhoeae and by off-label TMA-based Trichomonas vaginalis and Mycoplasma genitalium testing. A subset provided specimens at 6-month and 12-month follow-up visits.

RESULTS

Prevalence of M. genitalium from rectal and urine specimens (21.7% and 8.9%, respectively) exceeded that of C. trachomatis (8.8% and 1.6%) and other STI agents. Black participants yielded higher prevalence of M. genitalium (30.6%) than non-black participants (17.0%; χ²=22.39; p<0.0001). M. genitalium prevalence from rectal specimens was 41.5% in HIV-positive participants vs 16.3% in HIV-negative participants (χ²=57.72; p<0.0001). Participant age, gender identity, condomless insertive anal/vaginal sexual practice and condomless receptive anal sexual practice were not associated with rectal C. trachomatis (p≥0.10), N. gonorrhoeae (p≥0.29), T. vaginalis (p≥0.18) or M. genitalium (p≥0.20) detection. While prevalence of T. vaginalis was calculated at ≤1.0%, baseline rectal and urine screening status was predictive of detection/non-detection at follow-up. A non-reactive M. genitalium baseline rectal or urine screening result was less predictive of non-reactive follow-up versus C. trachomatis, N. gonorrhoeae and T. vaginalis.

CONCLUSIONS

Rectal M. genitalium detection is associated with black race and HIV seropositivity. Baseline M. genitalium infection influences subsequent detection of the organism.

A Quality Improvement Project Using Microlearning to Increase Provider Adherence to Extragenital Sexually Transmitted Infection Screening Guidelines in Men Who Have Sex With Men

ABSTRACT

The Centers for Disease Control and Prevention (CDC) recommend screening men who have sex with men who are living with HIV for sexually transmitted infections at appropriate extragenital contact sites for bacterial sexually transmitted infections. In an effort to increase provider adherence to CDC recommended guidelines at a Ryan White Clinic, microlearning educational sessions were used. A quality improvement project was designed to determine the rate of provider adherence to CDC guidelines pre/post microlearning sessions. Student t-test was used to compare the number of patients who received urine and extragenital screening to those who received urine-only screening, to before and after the microlearning sessions. The rate of extragenital screening significantly increased after the microlearning sessions (4/460 vs. 70/507, p < .0001). The rate of urine screening remained unchanged (p = 1). Although extragenital screening significantly increased, it remained low. A decision tree in the electronic medical record to prompt providers to screen was developed.

Barriers and Facilitators to Promoting Resilience to HIV/AIDS: A Qualitative Study on the Lived Experiences of HIV-Positive, Racial and Ethnic Minority, Middle-Aged and Older Men Who Have Sex with Men from Ontario, Canada

Evidence-based research has highlighted the need for exploring factors that support the mental health of men who have sex with men living with HIV/AIDS (MSMLWH), and environmental influences that promote their resilience to HIV/AIDS. This exploratory study utilized a community-based participatory research approach to investigate barriers and facilitators to promoting resilience to HIV/AIDS, specifically among racial and ethnic minority, middle-aged and older MSMLWH, a population that continues to be significantly impacted by HIV/AIDS today. This collaborative, qualitative study recruited participants who identified as racial or ethnic minority MSMLWH, were aged 40 or older, and resided in Ontario, Canada. Participants (n = 24) discussed in their interviews barriers and facilitators to promoting resilience to HIV/AIDS, which they recognized from their lived experiences. Utilizing thematic analysis, themes related to barriers and facilitators to promoting resilience to HIV/AIDS were identified. Themes related to identified barriers included: (1) language proficiency, (2) racism, (3) pernicious norms in North American gay culture, and (4) HIV stigma. Themes related to identified facilitators included: (1) compartmentalization, (2) perseverance, and (3) community-based health and social services. This article discusses the implications of the study’s findings, particularly on how they may influence the development of future services for racial and ethnic minority, middle-aged and older MSMLWH.

Sexually Transmitted Infections Treatment Guidelines, 2021

These guidelines for the treatment of persons who have or are at risk for sexually transmitted infections (STIs) were updated by CDC after consultation with professionals knowledgeable in the field of STIs who met in Atlanta, Georgia, June 11-14, 2019. The information in this report updates the 2015 guidelines. These guidelines discuss 1) updated recommendations for treatment of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis; 2) addition of metronidazole to the recommended treatment regimen for pelvic inflammatory disease; 3) alternative treatment options for bacterial vaginosis; 4) management of Mycoplasma genitalium; 5) human papillomavirus vaccine recommendations and counseling messages; 6) expanded risk factors for syphilis testing among pregnant women; 7) one-time testing for hepatitis C infection; 8) evaluation of men who have sex with men after sexual assault; and 9) two-step testing for serologic diagnosis of genital herpes simplex virus. Physicians and other health care providers can use these guidelines to assist in prevention and treatment of STIs.

Sexually Transmitted Infection/HIV Testing Among Medicaid/Children's Health Insurance Program-Insured Enrollees Aged 15 to 60 Years Who Were Diagnosed With High-Risk Sexual Behaviors With Their Opposite-Sex or Same-Sex Partners

BACKGROUND

There is a lack of information on high-risk sexual behaviors (HRSB) related to gender of sex partner and associated sexually transmitted infection (STI)/HIV testing among Medicaid enrollees.

METHODS

We used the 2016 Centers for Medicare & Medicaid Services Medicaid claims data to identify enrollees aged 15 to 60 years with HRSB by International Classification of Disease, Tenth Revision codes (Z72.51, Z72.52, and Z72.53). Enrollees diagnosed with HRSB were classified into 2 groups:(1) with same-sex partners and (2) with opposite-sex partners. The date when the initial diagnosis for HRSB was documented was used to define as the index date. We assessed chlamydia, gonorrhea, syphilis, and HIV testing on the index date, in the 6-month period before and after the index date (excluded the index date). HIV testing was limited to enrollees without documented HIV infection.

RESULTS

Of 50 million Medicaid enrollees aged 15 to 60 years, 1.2% were identified as enrollees with HRSB in 2016. Of those enrollees with HRSB, 2.7% were enrollees with same-sex partners and 0.71% had documented HIV infection. Chlamydia, gonorrhea, syphilis, and HIV testing rates were 82.4%, 81.9%, 33.2%, and 44.3%, respectively, at the index date. The chlamydia testing rate was ≥90% among enrollees who resided in the West compared with 53% to 61% across other regions. HIV testing was more likely among males and among those with same-sex partners. Sexually transmitted infection/HIV testing was <30% in the 6-month periods before and after the index date.

CONCLUSIONS

Among Medicaid enrollees with HRSB, STI/HIV testing varied regionally. Many enrollees were not tested for STI/HIV at the index visit in which they were identified as HRSB.

Opt-Out, Routine Emergency Department Syphilis Screening as a Novel Intervention in At-Risk Populations

BACKGROUND

With syphilis rates rising rapidly in the United States, novel means of reaching high-risk populations for screening and treatment are needed. Building on successful models for emergency department (ED) HIV screening, a routine opt-out syphilis screening program was implemented in a large, urban, tertiary care hospital ED in May 2019. This study aims to assess the prevalence of syphilis in this population and to evaluate the routine, opt-out syphilis screening model.

METHODS

A retrospective chart review was performed of all patients screened for syphilis in the ED from June to December 2019. Demographic information, HIV status, chief complaint, and follow-up visits were examined.

RESULTS

During the study period, 9198 people aged 18 to 64 years were screened for syphilis. Of these, 97 (1.1%) had presumed active syphilis infection (PAI), 354 (3.8%) were presumed not to have active syphilis, and 8747 (95.1%) were negative for infection. Patients with PAI were more likely to be male (67%; adjusted odds ratio, 3.5; 95% confidence interval, 2.3-5.3; P < 0.001), although the percentage of women was considerably higher than the nationally reported rate, and most were non-Hispanic Black (93.8%). Among patients with PAI, 23 (23.7%) were HIV positive. Only 18.6% of patients with PAI presented with complaints related to sexually transmitted infections.

CONCLUSIONS

Syphilis rates in this community are very high, and many infections were found in populations traditionally considered at lower risk by demographic or presenting complaint, indicating that universal screening is needed. Routine ED syphilis screening in high-prevalence communities will be critical to addressing the syphilis epidemic.

Chlamydia and Gonorrhea Incidence and Testing Among Patients in the Human Immunodeficiency Virus Outpatient Study (HOPS), 2007-2017

BACKGROUND

Although chlamydia (CT) and gonorrhea (GC) infections are increasing in the United States, there are limited data on their incidence, testing rates, and associated risk factors among persons living with HIV (PLWH), including by anatomic site among men who have sex with men (MSM).

METHODS

We analyzed 2007-2017 medical records data from Human Immunodeficiency Virus (HIV) Outpatient Study (HOPS) participants in care at 9 HIV clinics. We calculated CT (and GC) incidence and testing rates and assessed associations with sociodemographic and clinical factors using log-linear regression.

RESULTS

Among 4727 PLWH, 397 had 881 CT infections and 331 had 861 GC infections, with an incidence of 2.95 and 2.88 per 100 person-years, respectively. From 2007 to 2017, incidence and testing rates increased by approximately 3.0- and 1.9-fold for CT and GC, respectively. Multivariable factors associated with incident CT (GC) included younger age, MSM, and prior diagnoses of sexually transmitted diseases (STDs). Among 1159 MSM, 583 (50.3%) had 844 CT and 843 GC tests during 2016-2017, and 26.6% of tests were 3-site (urethra, rectum, and pharynx), yielding the highest rates of CT (GC) detection. Multivariable factors associated with CT (GC) testing included younger age, non-Hispanic/Latino black race, and having prior STDs.

CONCLUSIONS

Recent CT and GC incidence and testing increased among PLWH; however, only half of MSM were tested for CT or GC during 2016-2017 and less than a third of tests were 3-site. To promote sexual health and STD prevention among PLWH who are MSM, research regarding the added value of CT and GC testing across 3 anatomic sites is needed.

Extragenital Testing for Neisseria gonorrhoeae and Chlamydia trachomatis in a Large HIV Clinic in the US South: Implementation and Epidemiology

BACKGROUND

Rectal and oral Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) infections are common among people with HIV, especially men who have sex with men (MSM); however, GC/CT testing rates remain low in many HIV clinics. We evaluated the real-world implementation and results of extragenital nucleic acid amplification testing for GC/CT in an urban HIV clinic.

METHODS

Electronic health records were reviewed for all patients 18 years or older with ≥1 outpatient visit to an HIV clinic in Dallas, TX, from February 2016 to May 2019. Extragenital nucleic acid amplification testing became available in February 2017, which was followed by active interventions to increase testing.

RESULTS

Overall, 5564 individual patients were included in the preintervention period (February 2016-January 2017), 5067 in the intervention period (February 2017-August 2017), and 7030 in the postintervention period (September 2017-May 2018). Tailored education was provided to patients, and nursing and medical providers, and a self-collection protocol was implemented beginning in spring 2017. A sustained increase in extragenital GC/CT testing among MSM patients, from 70% to 87% (P < 0.01), was observed. Among MSM, overall GC positivity increased from 3.2% to 8.5% and CT positivity increased from 3.9% to 8.3%. N. gonorrhoeae/C. trachomatis infections were highest among young (<35 years) MSM, and approximately 50% of GC/CT infections diagnosed were detected by oral and rectal tests.

CONCLUSIONS

Clinic-wide education and self-collection of extragenital specimens were associated with increased GC/CT testing and detection in a large HIV clinic.

An update on the performance of STI services for gay and bisexual men across European cities: results from the 2017 European MSM Internet Survey

OBJECTIVES

Rectal STIs compromise health and are common in men who have sex with men (MSM). However, the European-MSM-Internet-Survey (EMIS-2010) showed that in 2010, the prevalence of anal swabbing during STI screening by MSM varied widely across 40 European cities. In this paper, we replicate a variety of measures of STI testing performance using 2017-18 data and extending the geographic spread of the analysis.

METHODS

Data were analysed from the EMIS-2017, a 33-language online sexual health survey accessible from 18 October 2017 to 31 January 2018. We focus on a subsample of 38 439 respondents living in the same 40 European cities we reported on in 2010. For a broader perspective, we also included an additional 65 cities in the analysis (combined n=56 661). We compared the prevalence of STI screening in MSM and disclosure of same-sex sexual contacts to the healthcare provider. We applied multivariable logistic regression models to compare the odds of MSM receiving each of four diagnostic procedures, including anal swabbing in the previous 12 months, controlling for age, HIV diagnosis, pre-exposure prophylaxis use and number of sexual partners.

RESULTS

In 2017, across 40 European cities, the proportion of respondents screened for STIs ranged from under 19% in Belgrade to over 59% in London. At an individual level, in comparison to London, the adjusted OR (AOR) of having received anal swabbing ranged from 0.03 in Belgrade, Bucharest and Istanbul to 0.80 in Oslo, with little evidence for a difference in Amsterdam and Dublin. Since 2010, most cities in West and South-west Europe have substantially narrowed their performance gap with London, but some in East and South-east Europe have seen the gap increase.

CONCLUSIONS

Although comprehensive STI screening in MSM has expanded across many European cities, the low prevalence of anal swabbing indicates that rectal STIs continue to be underdiagnosed, particularly in East/South-east Europe.

Testing practices and incidence of chlamydial and gonococcal infection in the Veterans Health Administration, 2009-2019

BACKGROUND

Chlamydia trachomatis and Neisseria gonorrhoeae cases reached a record high in the United States in 2018. Although active duty military servicemembers have high rates of chlamydia and gonorrhea infection, trends in chlamydia and gonorrhea in the Veterans Health Administration (VHA) system have not been previously described, including among patients with human immunodeficiency virus (HIV) and young women.

METHODS

We identified all Veterans in VHA care from 2009-2019. Tests and cases of chlamydia and gonorrhea were defined based on lab results in the electronic health record. Chlamydia and gonorrhea incidence rates were calculated each year by demographic group and HIV status.

RESULTS

In 2019, testing for chlamydia and gonorrhea occurred in 2.3% of patients, 22.6% of women ages 18-24, and 34.1% of persons with HIV. 2019 incidence of chlamydia and gonorrhea was 100.8 and 56.3 cases per 100,000 VHA users, an increase of 267% and 294%, respectively, since 2009. Veterans aged <34 years accounted for 9.5% of the VHA population but 66.9% of chlamydia and 42.9% of gonorrhea cases. Chlamydia and gonorrhea incidence rates in persons with HIV were 1,432 and 1,687 per 100,000, respectively.

CONCLUSIONS

The incidence of chlamydia and gonorrhea rose dramatically from 2009-2019. Among tested persons, those with HIV had a 15.2-fold higher unadjusted incidence of chlamydia and 34.9-fold higher unadjusted incidence of gonorrhea compared to those without HIV. VHA-wide adherence to chlamydia and gonorrhea testing in high-risk groups merits improvement.

Extragenital Gonorrhea and Chlamydia Positivity and the Potential for Missed Extragenital Gonorrhea With Concurrent Urethral Chlamydia Among Men Who Have Sex With Men Attending Sexually Transmitted Disease Clinics-Sexually Transmitted Disease Surveillance Network, 2015-2019

BACKGROUND

Extragenital gonorrhea (GC) and chlamydia (CT) are usually asymptomatic and only detected through screening. Ceftriaxone plus azithromycin is the recommended GC treatment; monotherapy (azithromycin or doxycycline) is recommended for CT. In urethral CT-positive/urethral GC-negative persons who are not screened extragenitally, CT monotherapy can lead to GC undertreatment and may foster the development of gonococcal antimicrobial resistance. We assessed urethral and extragenital GC and CT positivity among men who have sex with men (MSM) attending sexually transmitted disease clinics.

METHODS

We included visit data for MSM tested for GC and CT at 30 sexually transmitted disease clinics in 10 jurisdictions during January 1, 2015, and June 30, 2019. Using an inverse-variance random effects model to account for heterogeneity between jurisdictions, we calculated weighted test visit positivity estimates and 95% confidence intervals (CI) for GC and CT at urethral and extragenital sites, and extragenital GC among urethral CT-positive/GC-negative test visits.

RESULTS

Of 139,718 GC and CT test visits, we calculated overall positivity (GC, 16.7% [95% CI, 14.4-19.1]; CT, 13.3% [95% CI, 12.7-13.9]); urethral positivity (GC, 7.5% [95% CI, 5.7-9.3]; CT, 5.2% [95% CI, 4.6-5.8]); rectal positivity (GC, 11.8% [95% CI, 10.4-13.2]; CT, 12.6% [95% CI, 11.8-13.4]); and pharyngeal positivity (GC, 9.1% [95% CI, 7.9-10.3]; CT, 1.8% [95% CI, 1.6-2.0]). Of 4566 urethral CT-positive/GC-negative test visits with extragenital testing, extragenital GC positivity was 12.5% (95% CI, 10.9-14.1).

CONCLUSIONS

Extragenital GC and CT were common among MSM. Without extragenital screening of MSM with urethral CT, extragenital GC would have been undetected and undertreated in approximately 13% of these men. Undertreatment could potentially select for antimicrobial resistance. These findings underscore the importance of extragenital screening in MSM.

Transactional Sex and Incident Chlamydia and Gonorrhea Among Black Men Who Have Sex With Men in Atlanta, Georgia

BACKGROUND

Black men who have sex with men (BMSM) are disproportionately affected by sexually transmitted infections (STI), including chlamydia and gonorrhea. Transactional sex is an hypothesized risk factor for STI acquisition in BMSM.

METHODS

We estimated the association of transactional sex with incident chlamydia/gonococcal infection among BMSM using longitudinal data from a randomized trial in Atlanta (2012-2015). BMSM were eligible for inclusion if they tested human immunodeficiency virus (HIV)-antibody-negative and reported both ≥2 male sex partners and any condomless anal sex in the last year. We defined chlamydia/gonorrhea incidence as the first occurrence of either rectal or urogenital chlamydia or gonococcal infections after a negative result at enrollment. We used Poisson regression to estimate the incidence rate (IR) for chlamydia/gonorrhea over 12 months. Incidence rate ratios (IRR) compared estimates by reported experience of transactional sex. Subgroup analyses assessed potential heterogeneity by age and sexual identity.

RESULTS

This analysis included 416 BMSM, of whom 191 (46%) were gay-identified, 146 (42%) reported a history of transactional sex, and 57 (14%) had prevalent chlamydia/gonococcal infection at baseline. Over a median of 1 year of follow-up, an additional 55 men tested laboratory-positive for chlamydia/gonorrhea (IR, 17.3 per 100 person-years). Transactional sex was not associated with chlamydia/gonorrhea incidence overall. However, among gay-identified BMSM, transactional sex was associated with incident chlamydia/gonorrhea (IRR, 2.9; 95% confidence interval, 1.2-6.8).

CONCLUSIONS

Economic and social vulnerabilities may motivate engagement in high-risk sexual behaviors through commodified sex, potentially increasing the burden of STIs among BMSM. In this investigation, the relationship between transactional sex and chlamydia/gonorrhea was not homogenous across BMSM with diverse sexual identities in Atlanta, suggesting that within select sexual networks, transactional sex may drive STI risks. Delivering accessible and targeted STI screening for marginalized BMSM should be prioritized for STI and HIV prevention.

Lack of sexual behavior disclosure may distort STI testing outcomes

BACKGROUND

Men who have sex with men (MSM) globally have a high burden of curable sexually transmitted infections (STIs). MSM do not frequently receive rectal STI testing because of several barriers, such as not being out (disclosure of sexual behavior). We evaluate whether Chinese MSM select an STI test (rectal vs urethral) appropriate for their sexual behavior (insertive and/or receptive), and the interactions with being out.

METHODS

This was a secondary analysis of data from a cross sectional MSM survey conducted at a multisite randomized controlled trial (RCT) (December 2018 to January 2019) around uptake of gonorrhea and chlamydia testing among Chinese MSM (N = 431). We collected socio demographics, relevant medical and sexual history, and disclosure of sexual behavior (outness). We estimated the decision to test and test choice, and the extent to which disclosure plays a role in decision making.

RESULTS

Among 431 MSM, mean age was 28 years (SD = 7.10) and 65% were out to someone. MSM who indicated versatile sexual behavior and were out to someone had a 26.8% (95%CI = 6.1, 47.5) increased likelihood for selecting the rectal test vs the ure thral test, compared to those versatile and not out. Versatile MSM out to their health provider outside of the study context had a 29.4% (95%CI = 6.3, 52.6) greater likelihood for selecting the rectal STI test vs the urethral test, compared to versatile MSM not out to their health provider.

CONCLUSIONS

Sexual behavior and outness may affect gonorrhea and chlamydia testing provision. Apart from clinicians, community based efforts may reduce stigma based barriers to testing.

Factors associated with repeat rectal Neisseria gonorrhoeae and Chlamydia trachomatis screening following inconclusive nucleic acid amplification testing: A potential missed opportunity for screening

OBJECTIVE

Given rising incidence of Neisseria gonorrhoeae and Chlamydia trachomatis (GC/CT), development of efficacious screening strategies is critical to interruption of the infection cycle. However, a small proportion of nucleic acid amplification testing (NAAT) results are inconclusive-resulting in delays in diagnosis and treatment. As such, this study seeks to evaluate factors associated with inconclusive rectal GC/CT NAAT.

METHODS

This is a retrospective chart review of individuals who received an inconclusive rectal GC/CT NAAT result at a single institution from 3/2016-6/2018. Inconclusive GC/CT NAAT was defined as presence of PCR amplification inhibitors using Roche Cobas v2.0 CT/NG assay. Clinical charts were abstracted for age, gender, HIV status, GC/CT (urogenital, rectal, pharyngeal) and syphilis screening results during the study period, clinic type (HIV clinic, university student health center, other), and whether repeat testing occurred within 6 months following an inconclusive result. Logistic regression analysis was used to calculate adjusted and unadjusted odds ratios of factors associated with receipt of repeat testing following an inconclusive rectal GC/CT NAAT result.

RESULTS

During the study period, 6.1% (852/14,015) of rectal GC/CT NAAT were inconclusive for one or both of GC and CT. Among the 413 patients whose inconclusive rectal GC/CT NAAT results that were included in our analysis, 66.6% (275/413) received repeat testing within 6 months, of which 8.7% (24/275) were positive (compared to 5.4% positivity rate of all rectal samples). In multivariable analysis, individuals living with HIV had lower odds of receiving repeat testing following inconclusive rectal GC/CT NAAT compared to HIV uninfected individuals (adj OR 0.25; p = 0.001).

CONCLUSIONS

Despite being disproportionately affected by the STI epidemic, individuals living with HIV had 75% lower odds of receiving repeat testing following inconclusive rectal GC/CT NAAT compared to HIV-uninfected individuals, representing potentially missed opportunities for treatment and prevention of ongoing STI transmission.

Self-Reported Extragenital Chlamydia and Gonorrhea Testing in the Past 12 Months Among Men Who Have Sex with Men in the United States-American Men's Internet Survey, 2017

BACKGROUND

Current guidelines recommend that sexually active men who have sex with men (MSM) be screened at least annually for bacterial sexually transmitted infections (STIs) at sites of sexual contact regardless of condom use. Extragenital (rectal and pharyngeal) STI are common in MSM and associated with an increased risk of human immunodeficiency virus. We describe the prevalence of MSM who reported any STI test and an extragenital STI test in the past 12 months (p12m) in the United States.

METHODS

Data were obtained from the 2017 American Men's Internet Survey, an annual cross-sectional behavioral internet survey of MSM in the United States. We examined the prevalence of MSM who reported any STI test and an extragenital STI test in the p12m and compared the prevalence across demographic, clinical, and behavioral factors.

RESULTS

Of 10,049 sexually active MSM who participated in American Men's Internet Survey 2017, 42% reported any STI test in the p12m and 16% reported an extragenital (rectal or pharyngeal) STI test in the p12m. Among those who reported getting an extragenital STI test in the p12m, 19% reported providing a throat swab only, 14% reported providing a rectal swab only, and 68% reported providing both a rectal and throat swab for STI testing.

CONCLUSIONS

In a large sample of internet-using MSM in the United States, levels of STI screening were suboptimal, with fewer than half (42%) of MSM reporting any STI test and even fewer reporting an extragenital STI test in the p12m. Increased efforts are needed to ensure annual STI screening guidelines among MSM are implemented.

Health Care Provider Perceptions of a Sexually Transmitted Infection Self-testing Program in an HIV Care Clinic

BACKGROUND

Sexually transmitted infections (STIs) disproportionately affect men who have sex with men. Although clinical practice guidelines recommend routine STI screening of men who have sex with men who have high-risk behaviors, extragenital STI testing rates have been low in HIV clinics across the nation. The University of Washington STD Prevention Training Center implemented an STI self-testing program at a large HIV primary care clinic in Seattle, WA, to facilitate extragenital STI testing.

METHODS

We performed a mixed-methods program evaluation to assess health care provider acceptability of the program at 9 months after implementation. Twenty-eight clinicians were invited to complete an online survey. We conducted one-on-one, semistructured interviews with 6 clinicians and a focus group with 7 members of the clinic nursing staff. Survey responses were tallied. Conventional content analysis was performed on survey comments and transcripts from the interviews and focus group.

RESULTS

Ninety-one percent of clinicians were either satisfied or very satisfied with the program. Perceived advantages of the program included saving time for clinicians, overcoming patient discomfort, and increasing patient access to testing. Perceived program disadvantages included unclear responsibility of directing patients through the self-testing process and incorrect sample collection and labeling.

CONCLUSIONS

Despite perceived disadvantages, the self-testing program was acceptable to clinicians and nursing staff, key population for successful program adoption. Implementation of STI self-testing programs in clinic settings could help to increase extragenital STI testing rates by removing provider and patient barriers to testing.

Gonorrhoea and chlamydia in persons with HIV: number needed to screen

OBJECTIVES

Current guidelines recommend screening sexually active persons with HIV (PWH) for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) at least annually. Yet, screening rates in many HIV clinics remain low. In this study, we estimated the number needed to screen (NNS) to detect a NG and/or CT infection at each anatomic site among different subpopulations of PWH. NNS provides a concrete, practical measure to aid in assessing the practical impact of screening. METHODS : We included adults in care at three HIV Research Network sites in 2011-2014. Restricting to first tests within each year, annual NNS was defined as number of persons tested divided by number positive. We computed urogenital and extragenital NNS by age and risk group (women, men who have sex with women (MSW) and men who have sex with men (MSM)). RESULTS : A total of 16 864 NG/CT tests were included. Among patients aged ≤25 years, urogenital NNS was similar among women (15 (95% CI 6 to 71)), MSW (21 (95% CI 6 to 167)) and MSM (20 (95% CI 12 to 36)). Over 25, urogenital NNS increased to a greater extent for women (363 (95% CI 167 to 1000)) and MSW (160 (95% CI 100 to 333)) than MSM (46 (95% CI 38 to 56)). The increase for women versus MSM >25 remained significant (p<0.01) in multivariable analysis. Among MSM, rectal NNS was 5 (95% CI 3 to 7) and 10 (95% CI 9 to 12) for ≤25 and for >25 years and pharyngeal NNS values were 8 (95% CI 5 to 13) and 20 (95% CI 16 to 24).

CONCLUSIONS

These findings suggest the importance of regular, at least annual NG/CT screening, particularly extragenital, of HIV positive MSM of all ages. They provide some support for age-based cutoffs for women and MSW (eg, universal screening for those aged ≤25 and targeted screening for those aged >25 years).

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.

Evaluating the Impact of Housing Status on Gonorrhea and Chlamydia Screening in an HIV Primary Care Setting

INTRODUCTION

Gonorrhea and chlamydia (GC/CT) testing falls below recommended rates for people living with HIV (PLWH) in routine care. Despite evidence that homelessness and unstable housing (HUH) negatively impacts clinical outcomes for PLWH, little is known about GC/CT screening for HUH-PLWH in routine care.

METHODS

Using an observational cohort of PLWH establishing care at a large publicly funded HIV clinic in San Francisco between February 2013 and December 2014 and with at least 1 primary care visit (PCV) before February 2016, we assessed GC/CT testing for HUH (staying outdoors, in shelters, in vehicles, or in places not made for habitation in the last year) compared with stably housed patients. We calculated (1) the odds of having GC/CT screening at a PCV using logistic regression with random effects to handle intrasubject correlations and (2) the percent of time enrolled in clinical care in which patients had any GC/CT testing ("time in coverage") based on 180-day periods and using linear regression modeling.

RESULTS

Of 323 patients, mean age was 43 years, 92% were male, 52% were non-Latino white, and 46% were HUH. Homeless and unstably housed PLWH had 0.66 odds of GC/CT screening at a PCV than did stably housed patients (95% confidence interval, 0.44-0.99; P = 0.043). Time in coverage showed no difference by housing status (regression coefficient, -0.93; 95% confidence interval, -8.02 to 6.16; P = 0.80).

CONCLUSIONS

Homeless and unstably housed PLWH had 34% lower odds of GC/CT screening at a PCV, demonstrating a disparity in routine care provision, but similar time in coverage. More research is needed to effectively increase GC/CT screening among HUH-PLWH.

Rectal bleeding caused by a syphilitic inflammatory mass

A 47-year-old man presented with fatigue, decrease appetite, abdominal pain and rectal bleeding. His colonoscopy revealed a single, firm, raised, centrally ulcerated mass at the anorectal junction. During this same admission, he was diagnosed with HIV and syphilis, found to have multiple hepatic lesions and positive cerebrospinal fluidvenereal disease research laboratory test (VDRL). Biopsies from both the hepatic lesions and rectal ulcer showed spirochaetes by immunostaining. The initial presentation was felt to be secondary to a rectal inflammatory mass caused by syphilis.

Comparison of an in-house real-time duplex PCR assay with commercial HOLOGIC® APTIMA assays for the detection of Neisseria gonorrhoeae and Chlamydia trachomatis in urine and extra-genital specimens

BACKGROUND

Extra-genital Neisseria gonorrhoeae and Chlamydia trachomatis infections are mostly asymptomatic, and important reservoir sites of infection as they often go undetected and may be more difficult to eradicate with recommended therapeutic regimens. Commercial nucleic acid amplification tests (NAATs) have not received regulatory approval for the detection of N. gonorrhoeae and C. trachomatis in extra-genital specimens. The HOLOGIC® APTIMA Combo2 assay for N. gonorrhoeae and C. trachomatis has performed well in evaluations using extra-genital specimens.

METHODS

We assessed the performance of an in-house real-time duplex PCR assay for the detection of N. gonorrhoeae and C. trachomatis in urine and extra-genital specimens using the HOLOGIC® APTIMA assays as gold standard comparators. Urine, oropharyngeal and ano-rectal specimens were collected from each of 200 men-who-have-sex-with-men (MSM) between December 2011 and July 2012.

RESULTS

For N. gonorrhoeae detection, the in-house PCR assay showed 98.5-100% correlation agreement with the APTIMA assays, depending on specimen type. Sensitivity for N. gonorrhoeae detection was 82.4% for ano-rectal specimens, 83.3% for oropharyngeal specimens, and 85.7% for urine; and specificity was 100% with all specimen types. The positive predictive value (PPV) for N. gonorrhoeae detection was 100% and the negative predictive value (NPV) varied with sample type, ranging from 98.5-99.5%. For C. trachomatis detection, correlation between the assays was 100% for all specimen types. The sensitivity, specificity, PPV and NPV of the in-house PCR assay was 100% for C. trachomatis detection, irrespective of specimen type.

CONCLUSION

The in-house duplex real-time PCR assay showed acceptable performance characteristics in comparison with the APTIMA® assays for the detection of extra-genital N. gonorrhoeae and C. trachomatis.

Prevalence of Gonorrhea and Chlamydia Testing by Anatomical Site Among Men Who Have Sex With Men in HIV Medical Care, United States, 2013-2014

Fewer than one-third of men who have sex with men were tested for Neisseria gonorrhoeae or Chlamydia trachomatis as part of HIV medical care in the United States in 2013 to 2014, and only 11.6% were tested for either sexually transmitted disease at an extragenital site.

Self-Reported Chlamydia and Gonorrhea Testing and Diagnosis Among Men Who Have Sex With Men-20 US Cities, 2011 and 2014

BACKGROUND

Annual screening for chlamydia and gonorrhea is recommended for sexually active men who have sex with men (MSM) at anatomical sites of contact, regardless of condom use.

METHODS

We assessed differences in self-reported chlamydia and gonorrhea testing and diagnosis in the past 12 months among MSM using National HIV Behavioral Surveillance data from 2011 and 2014. Men who have sex with men who had 1 or more partners in the past 12 months were included in analyses. Analyses of chlamydia and gonorrhea diagnosis data were limited to participants who reported past 12 months chlamydia and gonorrhea testing, respectively. Differences in testing and diagnosis over time were assessed using Poisson regression models with robust standard errors separately for chlamydia and gonorrhea.

RESULTS

Analyses included data from 18,896 MSM (2011, n = 9256; 2014, n = 9640). Testing for chlamydia was 37% in 2011 and 47% in 2014 (prevalence ratio [PR], 1.25; 95% confidence interval [CI], 1.20-1.30) and 38% and 47% for gonorrhea (PR, 1.24; 95% CI, 1.19-1.29). Testing was higher in 2014 among most demographic subgroups. Prevalence of chlamydia diagnoses was 8% in 2011 and 11% in 2014 (PR, 1.37; 95% CI, 1.18-1.59) and of gonorrhea diagnoses was 10% in 2011 and 14% in 2014 (adjusted PR: 1.40, 95% CI, 1.23-1.60). Larger changes in diagnoses were observed among MSM in the white and "other" racial categories and those who disclosed same-sex behavior to their health care provider.

CONCLUSIONS

Self-reported testing and diagnoses among MSM increased from 2011 to 2014. Increased efforts are needed to meet annual sexually transmitted disease screening recommendations among MSM at high HIV risk.

Sexually transmitted infections among young men who have sex with men: Experiences with diagnosis, treatment, and reinfection

Despite high rates of sexually transmitted infections (STIs) among young men who have sex with men (YMSM), little is known about their experiences with diagnosis, treatment, and reinfection. To fill this gap, we interviewed 17 YMSM ages 18-29 who participated in an online HIV prevention trial and tested positive for STIs at both the baseline and three-month follow-up assessments. Participants were asked about their reactions to testing positive, experiences with treatment, disclosure to partners, and changes in thinking and behavior. Reactions were diverse, the most common being surprise and concern. Most participants sought treatment, although type of provider varied (e.g., primary care physician, clinic that specialized in gay/bisexual men's health). Providers tended to re-test participants, but some did so at the incorrect anatomical site. Participants who felt comfortable talking to providers about STIs tended to use their regular provider or one who specialized in gay/bisexual men's health. Most participants described changes in their thinking and behavior (e.g., increased condom use, decreased sex partners, questioning their partners' trust). Most participants disclosed to at least one partner, but some did not remember or were not in contact with partners. Experiences were similar the first and second time participants tested positive for STIs during the study with a few exceptions (e.g., more self-blame and comfort talking to providers the second time). In sum, YMSM have diverse experiences with STI diagnosis and treatment. Implications for public policy and STI prevention are discussed.

The ANRS-Ipergay trial, an opportunity to use qualitative research to understand the perception of the "participant"-physician relationship

The ANRS-IPERGAY trial consisted in providing sexual activity-based antiretroviral prophylaxis for HIV prevention (PrEP) with a package of prevention tools (counselling, condoms, HIV and sexually transmitted infections' screening) to highly exposed HIV-negative men who have sex with men (MSM). Few data exist concerning the patient-physician relationship in the particular context of PrEP, where physicians discuss sexual behaviours with MSM who are not classic patients, in that consultation is for prevention purposes, not for illness. This study took place during the open-label extension of ANRS-IPERGAY trial when all participants received PrEP. In this qualitative study, we examined how physicians perceived their relationship with participants in the ANRS-IPERGAY trial. Of all 30 physicians involved in the trial who were contacted by email to participate in an interview about their opinions and perceptions of ANRS-IPERGAY 18 volunteered to participate in the current sub-study. We performed a vertical analysis for each interview to identify the extract in each physician's discourse concerning their relationship with MSM participants, and conducted a horizontal analysis to construct the thematic tree and subsequently investigate differences and similitudes between themes. An analysis of all physicians' discourses showed that the participant-physician relationship during the trial could be described through 4 themes: (i) personal experience of the relationship, (ii) trust and non-judgement, (iii) positive relational climate and (iv) influence of physician's characteristics (age, gender, etc.) on relationship. We found that the particular context of PrEP led some physicians to adopt a patient-as-partner approach during consultations rather than a paternalist or hierarchical approach. Indeed, the close follow-up provided by the trial and the active role of patients in their own prevention care trajectory, are more compatible with the patient-as-partner approach. The prescription of PrEP may lead to an evolution in patient-physician relationships and may even modify the professional identity of physicians.

Is Patient-Reported Exposure a Reliable Indicator for Anogenital Gonorrhea and Chlamydia Screening in Young Black Men Who Have Sex With Men?

Among 485 young black men who have sex with men recruited in Jackson, MS, 90-day anal sexual exposure significantly predicted rectal infection, but 19.4% of rectal infections would have been missed among men denying receptive anal sex. Reports of consistent condom use were associated with lower infection rates only in men reporting insertive anal sex.

Prevalence and Risk Factors for Rectal and Urethral Sexually Transmitted Infections From Self-Collected Samples Among Young Men Who Have Sex With Men Participating in the Keep It Up! 2.0 Randomized Controlled Trial

BACKGROUND

Despite recommendations that sexually active men who have sex with men be regularly tested for sexually transmitted infections (STIs) and that testing reflect anatomical sites of potential exposure, regular testing is not widely performed, especially for rectal STIs. As such, little is known about the prevalence of rectal and urethral STIs among young men who have sex with men (YMSM).

METHODS

The current study examined the prevalence and risk factors for rectal and urethral chlamydia and gonorrhea in a sample of 1113 YMSM ages 18 to 29 years (mean, 24.07 years). Before participating in a randomized controlled trial for an online human immunodeficiency virus prevention program (Keep It Up! 2.0), participants completed self-report measures and self-collected urine and rectal samples. Participants mailed samples to a laboratory for nucleic acid amplification testing. Viability of self-collected samples was examined as a potential method to increase STI screening for MSM without access to STI testing clinics.

RESULTS

Results indicated that 15.1% of participants tested positive for an STI, 13.0% for a rectal STI, 3.4% for a urethral STI, and 1.2% for both rectal and urethral STIs. Rectal chlamydia was significantly more common (8.8%) than rectal gonorrhea (5.0%). Rectal STIs were higher among black YMSM compared with white YMSM. Additionally, rectal STIs were positively associated with condomless receptive anal sex with casual partners.

CONCLUSIONS

Findings call attention to the need for health care providers to test YMSM for rectal STIs. This study also demonstrates the viability of including self-collected samples for STI testing in an eHealth program.

Syphilis incidence in men who have sex with men with human immunodeficiency virus comorbidity and the importance of integrating sexually transmitted infection prevention into HIV care

INTRODUCTION

Syphilis continues to be a growing epidemic among men who have sex with men (MSM), particularly for those living with the human immunodeficiency virus (HIV). In 2016, MSM accounted for 80% of primary and secondary syphilis diagnoses in men in the United States; almost half of who were also HIV-infected. The synergistic relationship between HIV and syphilis has significant implications not only for HIV patient management, but also for sexually transmitted infection (STI) control among MSM. Areas covered: We review the literature on STI screening and treatment barriers at the patient-, provider-, and health system-levels, and present strategies to incorporate STI prevention into HIV care settings. Expert commentary: Integration of STI prevention into HIV care is paramount to stop the epidemic of not only syphilis, but also other curable STIs like gonorrhea and chlamydia. Although guidelines have been established for STI testing in HIV-infected MSM, screening rates continue to be lower than desired. Gonorrhea and chlamydia screening is below 50% in HIV-infected MSM; interventions that improve testing of those two infections must be implemented. For syphilis control, other additional strategies such as chemoprophylaxis should be considered given syphilis screening is above 50% in HIV-infected MSM.

Sexually Transmitted Disease Testing of Human Immunodeficiency Virus-Infected Men Who Have Sex With Men: Room for Improvement

BACKGROUND

In the United States, sexually transmitted infection (STI) testing is recommended at least annually for sexually active men who have sex with men (MSM). We evaluated human immunodeficiency virus (HIV) providers' STI testing practices and frequency of positive test results.

METHODS

We analyzed data from HIV Outpatient Study (HOPS) participants who, from 2007 to 2014, completed a confidential survey about risk behaviors. Using medical records data, we assessed the frequency of gonorrhea, chlamydia, and syphilis testing and positive results during the year after the survey for MSM who reported sex without a condom in the prior 6 months. We compared testing frequency and positivity for men having 1, 2 to 3, and 4 or more sexual partners. Correlates of STI testing were assessed using general linear model to derive relative risks (RR) with associated 95% confidence intervals (CI).

RESULTS

Among 719 MSM, testing frequency was 74.5%, 74.3%, and 82.9% for gonorrhea, chlamydia, and syphilis, respectively, and was higher in those men who reported more sexual partners (P < 0.001 for all). In multivariable analysis, testing for gonorrhea was significantly more likely among non-Hispanic black versus white men (RR, 1.17; 95% CI, 1.03-1.33), among men seen in private versus public clinics (RR, 1.16; 95% CI, 1.05-1.28), and among men with 2 to 3 and 4 or more sexual partners versus 1 partner (RR, 1.12; 95% CI, 1.02-1.23, and RR, 1.18; 95% CI, 1.08-1.30, respectively). Correlates of chlamydia and syphilis testing were similar. Test positivity was higher among men with more sexual partners: for gonorrhea 0.0%, 3.0%, and 6.7% for men with 1, 2 to 3, and 4 or more partners, respectively (P < 0.001, syphilis 3.7%, 3.8% and 12.5%, P < 0.001).

CONCLUSIONS

Among HIV-infected MSM patients in HIV care who reported sex without a condom, subsequent testing was not documented in clinic records during the following year for up to a quarter of patients. Exploring why STI testing did not occur may improve patient care.

Gonorrhea and Chlamydia Case Detection Increased When Testing Increased in a Multisite US HIV Cohort, 2004-2014

OBJECTIVES

Annual screening for gonorrhea [Neisseria gonorrhoeae (NG)] and chlamydia [Chlamydia trachomatis (CT)] is recommended for all sexually active persons living with HIV but is poorly implemented. Studies demonstrating no increases in NG and/or CT (NG/CT) case detection in clinics that successfully expanded NG/CT screening raise questions about this broad screening approach. We evaluated NG/CT case detection in the HIV Research Network during 2004-2014, a period of expanding testing.

METHODS

We analyzed linear time trends in annual testing (patients tested divided by all patients in care), test positivity (patients positive divided by all tested), and case detection (the number of patients with a positive result divided by all patients in care) using multivariate repeated measures logistic regression. We determined trends overall and stratified by men who have sex with men (MSM), men who have sex exclusively with women, and women.

RESULTS

Among 15,614 patients (50% MSM, 26% men who have sex exclusively with women, and 24% women), annual NG/CT testing increased from 22% in 2004 to 60% in 2014 [adjusted odds ratio (AOR) per year 1.22 (1.21-1.22)]. Despite the increase in testing, test positivity also increased [AOR per year 1.10 (1.07-1.12)], and overall case detection increased from 0.8% in 2004 to 3.9% in 2014 [AOR per year 1.20 (1.17-1.22)]. Case detection was highest among MSM but increased over time among all 3 groups.

CONCLUSIONS

NG/CT case detection increased as testing expanded in the population. This supports a broad approach to NG/CT screening among persons living with HIV to decrease transmission and complications of NG/CT and of HIV.

Sexually Transmitted Infections Among HIV-Infected Individuals in the District of Columbia and Estimated HIV Transmission Risk: Data From the DC Cohort

Background

Washington, DC, has one of the highest rates of HIV infection in the United States. Sexual intercourse is the leading mode of HIV transmission, and sexually transmitted infections (STIs) are a risk factor for HIV acquisition and transmission.

Methods

We evaluated the incidence and demographic factors associated with chlamydia, gonorrhea, and syphilis among HIV-infected persons enrolled at 13 DC Cohort sites from 2011 to 2015. Using Poisson regression, we assessed covariates of risk for incident STIs. We also examined HIV viral loads (VLs) at the time of STI diagnosis as a proxy for HIV transmission risk.

Results

Six point seven percent (451/6672) developed an incident STI during a median follow-up of 32.5 months (4% chlamydia, 3% gonorrhea, 2% syphilis); 30% of participants had 2 or more STI episodes. The incidence rate of any STIs was 3.8 cases per 100 person-years (95% confidence interval [CI], 3.5-4.1); age 18-34 years, 10.8 (95% CI, 9.7-12.0); transgender women, 9.9 (95% CI, 6.9-14.0); Hispanics, 9.2 (95% CI, 7.2-11.8); and men who have sex with men (MSM), 7.7 (95% CI, 7.1-8.4). Multivariate Poisson regression showed younger age, Hispanic ethnicity, MSM risk, and higher nadir CD4 counts to be strongly associated with STIs. Among those with an STI, 41.8% had a detectable VL within 1 month of STI diagnosis, and 14.6% had a VL ≥1500 copies/mL.

Conclusions

STIs are highly prevalent among HIV-infected persons receiving care in DC. HIV transmission risk is considerable at the time of STI diagnosis. Interventions toward risk reduction, antiretroviral therapy adherence, and HIV virologic suppression are critical at the time of STI evaluation.

Sexually Transmitted Infection Testing of HIV-Positive Medicare and Medicaid Enrollees Falls Short of Guidelines

BACKGROUND

Men who have sex with men with HIV have high sexually transmitted infection (STI) incidence. Thus, the Centers for Disease Control and Prevention (CDC) recommends at least yearly STI screening of HIV-infected individuals.

METHODS

We calculated testing rates for syphilis, chlamydia, and gonorrhea among HIV-positive Californians with Medicare or Medicaid insurance in 2010. Logistic regressions estimated how testing for each bacterial STI relates to demographic and provider factors.

RESULTS

Fewer than two-thirds of HIV-positive Medicare and fewer than three-quarters of Medicaid enrollees received a syphilis test in 2010. Screenings for chlamydia or gonorrhea were less frequent: approximately 30% of Medicare enrollees were tested for chlamydia or gonorrhea in 2010, but higher proportions of Medicaid enrollees were tested (45%-46%). Only 34% of HIV-positive Medicare enrollees who were tested for syphilis were also screened for chlamydia or gonorrhea on the same day. Nearly half of Medicaid enrollees were tested for all 3 STIs on the same day. Patients whose providers had more HIV experience had higher STI testing rates.

CONCLUSIONS

Testing rates for chlamydia and gonorrhea infection are low, despite the increase in these infections among people living with HIV and their close association with HIV transmission. Interventions to increase STI testing include the following: prompts in the medical record to routinely conduct syphilis testing on blood drawn for viral load monitoring, opt-out consent for STI testing, and provider education about the clinical importance of STIs among HIV-positive patients. Last, it is crucial to change financial incentives that discourage nucleic acid amplification testing for rectal chlamydia and gonorrhea infections.

The Cost-Effectiveness of Syphilis Screening Among Men Who Have Sex With Men: An Exploratory Modeling Analysis

We adapted a published model to estimate the costs and benefits of screening men who have sex with men for syphilis, including the benefits of preventing syphilis-attributable human immunodeficiency virus. The cost per quality-adjusted life year gained by screening was <US $0 (cost-saving) and US $16,100 in the dynamic and static versions of the model, respectively.

Implementation and Operational Research: Effectiveness and Patient Acceptability of a Sexually Transmitted Infection Self-Testing Program in an HIV Care Setting

BACKGROUND

Rates of screening for bacterial sexually transmitted infections (STI) among men who have sex with men in HIV care settings remain low despite high prevalence of these infections. STI self-testing may help increase screening rates in clinical settings.

METHODS

We implemented an STI self-testing program at a large, urban HIV care clinic and evaluated its effectiveness and acceptability. We compared measures obtained during the first year of the STI self-testing program (Intervention Year, April 1, 2013-March 31, 2014) to Baseline Year (January 1, 2012-December 31, 2012) to determine: (1) overall clinic change in STI testing coverage and diagnostic yield and; (2) program-specific outcomes including appropriate anatomic site screening and patient-reported acceptability.

RESULTS

Overall, testing for gonorrhea and chlamydia increased significantly between Baseline and Intervention Year, and 50% more gonococcal and 47% more chlamydial infections were detected. Syphilis testing coverage remained unchanged. Nearly 95% of 350 men who participated in the STI self-testing program completed site-specific testing appropriately based on self-reported exposures, and 92% rated their self-testing experience as "good" or "very good."

CONCLUSIONS

STI self-testing in HIV care settings significantly increases testing coverage and detection of gonorrhea and chlamydia, and the program is acceptable to patients. Additional interventions to increase syphilis screening rates are needed.

Increased Sexually Transmitted Disease Testing Among Sexually Active Persons Receiving Medical Care for Human Immunodeficiency Virus Infection in the United States, 2009-2013

Background

Current guidelines recommend that all sexually active human immunodeficiency virus (HIV)-infected persons be tested at least annually for syphilis, chlamydia, and gonorrhea. We examined temporal trends in syphilis, chlamydia, and gonorrhea testing among sexually active HIV-infected adults receiving medical care in the United States during 2009-2013.

Methods

Using medical record data from the Medical Monitoring Project, a population-based HIV surveillance system, we assessed the proportion of adults receiving HIV medical care who were tested for syphilis, chlamydia, and gonorrhea in the past 12 months by year and stratified by sex and sexual behavior, age, and race/ethnicity.

Results

During 2009-2013, the proportion of sexually active HIV-infected adults receiving medical care who were tested in the past year for all 3 examined sexually transmitted diseases (STDs) increased from 20% to 36% (PTREND < .01). Overall testing for syphilis increased from 55% to 65% (PTREND < .01), and significant increases were noted for the following subgroups: men who have sex with men (58% to 69%), non-Hispanic whites (48% to 64%), and all age groups with the exception of persons aged 18-29 year. Overall testing for chlamydia and gonorrhea increased from 22% to 42% (PTREND < .01), and significant increases were noted for most subgroups.

Conclusions

STD testing significantly increased among sexually active HIV-infected adults receiving medical care; however, the majority of persons were not tested for all 3 STDs in 2013. While increased testing indicates progress, testing remained far below recommended guidelines. Our findings suggest enhanced efforts may be warranted to screen all sexually active HIV-infected adults for syphilis, chlamydia, and gonorrhea.

Sexually Transmitted Disease Testing and Uptake of Human Papillomavirus Vaccine in a Large Online Survey of US Men Who Have Sex With Men at Risk for HIV Infection, 2012

National guidelines recommend annual human immunodeficiency virus (HIV)/sexually transmitted disease testing for sexually active men who have sex with men (MSM) and vaccination against human papillomavirus for MSM through age 26. A 2012 online survey of 2,794 MSM found that 51%, 36%, and 14% reported receiving human immunodeficiency virus testing, sexually transmitted disease testing, and human papillomavirus vaccination, respectively.

Characteristics Associated With Urethral and Rectal Gonorrhea and Chlamydia Diagnoses in a US National Sample of Gay and Bisexual Men: Results From the One Thousand Strong Panel

BACKGROUND

Gay and bisexual men are at elevated risk for Neisseria gonorrhoeae and Chlamydia trachomatis (GC/CT). Rectal GC/CT symptoms may be less obvious than urethral, increasing opportunities for undiagnosed rectal GC/CT.

METHODS

A US national sample of 1071 gay and bisexual men completed urethral and rectal GC/CT testing and an online survey.

RESULTS

In total, 6.2% were GC/CT positive (5.3% rectal, 1.7% urethral). We calculated adjusted (for education, race, age, relationship status, having health insurance, and income) odds ratios for factors associated with rectal and urethral GC/CT diagnoses. Age was inversely associated with urethral and rectal GC/CT. Compared with white men, Latinos had significantly greater odds of rectal GC/CT. Among men who reported anal sex, those reporting only insertive sex had lower odds of rectal GC/CT than did men who reported both insertive and receptive. There was a positive association between rectal GC/CT and number of male partners (<12 months), the number of anal receptive acts, receptive condomless anal sex (CAS) acts, and insertive CAS acts. Compared with those who had engaged in both insertive and receptive anal sex, those who engaged in only receptive anal sex had lower odds of urethral GC/CT. The number of male partners (<12 months) was associated with increased odds of urethral GC/CT.

CONCLUSIONS

Rectal GC/CT was more common than urethral and associated with some demographic and behavioral characteristics. Our finding that insertive CAS acts was associated with rectal GC/CT highlights that providers should screen patients for GC/CT via a full range of transmission routes, lest GC/CT go undiagnosed.

Rectal Infection With Neisseria gonorrhoeae and Chlamydia trachomatis in Men in the United States

BACKGROUND

 Centers for Disease Control and Prevention guidelines recommend at least annual rectal screening of men who have receptive anal intercourse for Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT). Only limited national data are available on the prevalence of rectal GC and CT infection among US men.

METHODS

 In collaboration with a large US commercial laboratory, we estimated positivity of the first rectal GC and CT test ("index" test) in men aged 15-60 years tested between January 2013 and May 2015. We estimated the frequency and positivity of pharyngeal or urine specimens tested for GC and CT on the index date, and the frequency and positivity of repeat rectal testing or any follow-up testing at any anatomic site after the index date.

RESULTS

 Of 52 063 tested men aged 15-60 years, approximately 6.1% were positive for GC only, 8.3% for CT only, and 2.7% for both GC and CT on their index date. On that date, 86.5% had either urine or pharyngeal specimens collected, and 56.1% had both specimens collected. Pharyngeal GC infection was highly associated with rectal GC infection. Follow-up testing after 12 months ranged from 42.4% among uninfected men to 56.7% among infected men on the index date. Positivity was at least 5.7% in rectal GC, rectal CT, or pharyngeal GC at their last test.

CONCLUSIONS

 This analysis of a large number of male rectal specimens tested for GC and CT suggest that routine testing and timely repeat rectal GC and CT testing should be prioritized among men who report receptive rectal sex.

Improvement of Sexually Transmitted Disease Screening Among HIV-Infected Men Who Have Sex With Men Through Implementation of a Standardized Sexual Risk Assessment Tool

BACKGROUND

Screening for gonorrhea (GC) and chlamydia (CT) and syphilis among HIV-positive (HIV+) men who have sex with men (MSM) is recommended at least annually. However, significant gaps in screening coverage exist. We conducted a quality improvement intervention to determine whether informing providers of preintervention screening rates and routinizing sexual risk assessment would improve sexually transmitted disease (STD) screening in a large HIV care clinic.

METHODS

In partnership with Kaiser Permanente Northern California, we developed and implemented a 10-item assessment addressing sexual and other behavioral risk factors among HIV+ MSM. We analyzed the proportion of patients screened for GC/CT and syphilis in a preintervention period (June 25-September 26, 2012) and during the intervention period (June 25-September 26, 2013).

RESULTS

Of 364 HIV+ MSM seen for care during the intervention period, 47.3% completed the sexual risk assessment. Improvements in GC/CT screening and syphilis screening were observed; when comparing the preintervention period with the intervention period, the proportion of HIV+ MSM receiving GC/CT screening increased by 26.8% (31.6%-40.1%, P = 0.01) at any anatomical site and by 45% (19.5%-28.3%, P = 0.003) at the pharyngeal site. Syphilis screening significantly increased by 18.8% (48.7%-58.0%, P = 0.009).

CONCLUSIONS

Overall STD screening increases were observed after this intervention that included didactic training on the urgency of STD screening needs for HIV+ MSM, a presentation of preintervention clinic STD screening data, and the implementation of self-reported sexual risk assessment. Additional efforts are needed to determine feasible ways to accurately assess the appropriateness of STD screening and success of interventions to improve STD screening.
