RESUMO

Availability of HIV self-testing may increase HIV testing frequency among men who have sex with men (MSM). It is unclear, however, if self-testing may impact HIV-related sexual behaviors among MSM, including HIV status disclosure and condom use. We conducted a mixed methods analysis of changes in HIV-related behaviors after HIV self-testing introduction, using data from 110 MSM participating in a feasibility and acceptability study of HIV self-testing in Mpumalanga Province, South Africa. We found increased HIV status disclosure from study participants to sexual partners after HIV self-testing introduction, from 61.8% at baseline to 75.5% at 6-month follow-up (p = 0.04), but decreased condom use with female partners (p = 0.03). Qualitative interviews reveal that some participants used test results to inform condom use. Distribution of self-testing kits can improve mutual disclosure, but should be accompanied by information stressing that the tests may not detect early HIV infections or other sexually transmitted infections.

RESUMO

Neisseria gonorrhoeae antimicrobial drug resistance has emerged worldwide; however, the situation in sub-Saharan Africa is not well documented. We investigated the molecular epidemiology and occurrence of antimicrobial resistance in Neisseria gonorrhoeae infections in two core transmission groups of men in Johannesburg, South Africa. We recruited men who have sex with men (MSM) presenting with urethral discharge and men with recurrent episodes of urethral discharge. Molecular testing and culture for N. gonorrhoeae were performed, followed by antimicrobial susceptibility testing. Whole-genome sequencing (WGS) was used to identify resistance-conferring mutations and to determine the genetic relatedness of the isolates. In all, 51 men were recruited; 42 (82%) had N. gonorrhoeae infections. Most gonococcal isolates were resistant to ciprofloxacin (78%) and tetracycline (74%); 33% were penicillin resistant. All gonococcal isolates were susceptible to cephalosporins and spectinomycin. Azithromycin resistance was observed in 4 (15%) isolates (epidemiological cutoff), all with mutations in the mtrR promoter region. Most of the isolates (19/27) harbored the gonococcal genetic island, which is associated with antimicrobial resistance. WGS revealed a diverse epidemic with mostly novel NG-STAR (70%) and NG-MAST (70%) sequence types. Thus, we demonstrate a high prevalence of antimicrobial resistance in Neisseria gonorrhoeae strains obtained from high-risk men in South Africa. The introduction of diagnostics and scale-up of surveillance are warranted to prevent the emergence of multidrug-resistant infections.

RESUMO

We observed a high rate of incident sexually transmitted diseases within 55 days (median) of follow-up (78% retention) among symptomatic men who have sex with men (n = 78) in South Africa (188 per 100 person-years; 95% confidence interval, 1.2-2.7); 16 newly acquired and 10 with persistent positivity. This highlights the need to strengthen prevention efforts, whereas introduction of diagnostics is urgently warranted.

RESUMO

BACKGROUND: Men who have sex with men (MSM) are a key population, particularly vulnerable to sexually transmitted infections (STIs) and HIV, but there are limited data on health programs targeting MSM in Africa. This study aims to describe the utilization of nongovernmental organization-supported sexual health services for MSM at 2 public sector health facilities in Johannesburg, South Africa. METHODS: We retrospectively analyzed routine data over the period of January 2014 to June 2016. We report on service utilization for STI syndromes, HIV testing, and the antiretroviral therapy (ART) program. RESULTS: Some 5796 men visited the facilities. Seven thousand one hundred eighty-eight STI episodes were managed, 68.2% (4903 episodes) of which were classified as male urethritis and 9.8% (704 episodes) as genital ulcers. Positivity yield for first-time HIV tests was 38.0% (205 positive test results) in MSM, compared with 14.1% (471 positive test results) in other men. At the end of the study, there were 1090 clients on ART, and 2-year retention was 82% (95% confidence interval, 78%-85%). There was no difference in retention between MSM and other men (P = 0.49). CONCLUSIONS: This study is the first to show that sexual health services targeting MSM in Africa have managed to attract MSM and other men in need of STI and HIV care. The observed high HIV testing yield among MSM illustrates the relevance of MSM-focused services in the South African public health sector, and the good retention on ART demonstrates that high-quality care can be provided to MSM in our setting.

RESUMO

In South Africa, HIV prevalence for gay, bisexual, and men who have sex with men (GBMSM) is as high as 49.5%, yet only 25.7% are taking treatment, resulting in transmission risk between partners and the need for dyadic interventions for men in relationships. Through our preliminary research, we identified the evidence-based intervention Healthy Relationships (HR)-an HIV risk assessment and status disclosure intervention for those in relationships-to be tailored into videoconference format for partnered HIV-positive GBMSM in South Africa. The HR adaptation, called SOAR (Speaking Out & Allying Relationships), applied a human-centered design approach. In-depth interviews were conducted with HIV-positive GBMSM (N = 15) to refine intervention preferences with results used to establish a beta SOAR. A trained interventionist conducted SOAR functionality (n = 6) and usability (n = 7) tests with separate invited groups composed of the original participants interviewed. Field logs, focus group discussions, and a study-specific preference survey were administered. Thematic analysis and descriptive statistics were completed with a convergent analytical approach used to understand usability. Overall experience of GBMSM in SOAR was good (69%) or excellent (31%). More than half of the participants (61%) rated using videoconferencing for SOAR as good, with 38% rating it as fair. All participants stated that SOAR was understandable and satisfactory with willingness to recommend it to other GBMSM. This adaptation approach was effective, and the resultant SOAR intervention has the potential to improve individual coping and HIV communication skills with partners to engage with biomedical prevention and in turn support GBMSM couples.

RESUMO

INTRODUCTION: Men who have sex with men (MSM) and transgender women (TGW) in sub-Saharan Africa (SSA) are profoundly affected by HIV with high HIV prevalence and incidence. This population also faces strong social stigma and legal barriers, potentially impeding participation in research. To date, few multi-country longitudinal HIV research studies with MSM/TGW have been conducted in SSA. Primary objective of the HIV Prevention Trials Network (HPTN) 075 study was to assess feasibility of recruiting and retaining a multinational prospective cohort of MSM/TGW in SSA for HIV prevention research. METHODS: HPTN 075, conducted from 2015 to 2017, was designed to enroll 400 MSM/TGW at four sites in SSA (100 per site: Kisumu, Kenya; Blantyre, Malawi; Cape Town, South Africa; and Soweto, South Africa). The number of HIV-positive persons was capped at 20 per site; HIV-positive persons already in care were excluded from participation. The one-year study included five biobehavioural assessments. Community-based input and risk mitigation protocols were included in study design and conduct. RESULTS: Of 624 persons screened, 401 were enrolled. One in five participants was classified as transgender. Main reasons for ineligibility included: (a) being HIV positive after the cap was reached (29.6%); (b) not reporting anal intercourse with a man in the preceding three months (20.6%); and (c) being HIV positive and already in care (17.5%). Five (1.2%) participants died during the study (unrelated to study participation). 92.9% of the eligible participants (368/396) completed the final study visit and 86.1% participated in all visits. The main, overlapping reasons for early termination included being (a) unable to adhere to the visit schedule, predominantly because of relocation (46.4%), and (b) unable to contact the participant (32.1%). Participants reported strong motivation to participate and few participation barriers. Four participants reported social harms (loss of confidentiality and sexual harassment by study staff) that were successfully addressed. CONCLUSIONS: HPTN 075 successfully enrolled a multinational sample of MSM/TGW in SSA in a prospective HIV prevention research study with a high retention rate and few documented social harms. This supports the feasibility of conducting large-scale research trials in this population to address its urgent, unmet HIV prevention needs.

RESUMO

This study from South Africa highlights the importance of rectal Trichomonas vaginalis infection as a sexually transmitted infection among men who have sex with men (MSM). We report seven MSM presenting with rectal T. vaginalis infection. Two men presented with symptoms of proctitis; 5/7 had urethral coinfection with T. vaginalis. Rectal T. vaginalis infection should be considered in MSM in areas where genital infection is endemic.

RESUMO

BACKGROUND: HIV self-testing (HIVST) may increase HIV testing uptake, facilitating earlier treatment for key populations like MSM who experience barriers accessing clinic-based HIV testing. HIVST usability among African MSM has not been explored. METHODS: We assessed usability of oral fluid (OF) and fingerstick (FS; blood) HIVST kits during three phases among MSM with differing degrees of HIVST familiarity in Mpumalanga, South Africa. In 2015, 24 HIVST-naïve MSM conducted counselor-observed OF and FS HIVST after brief demonstration. In 2016 and 2017, 45 and 64 MSM with experience using HIVST in a pilot study chose one HIVST to conduct with a counselor-observer present. In addition to written, the latter group had access to video instructions. We assessed frequency of user errors and reported test use ease, changes in error frequency by phase, and covariates associated with correct usage using log-Poisson and Gaussian generalized estimating equations. RESULTS: Among OF users (n = 57), 15-30% committed errors in each phase; however, observers consistently rated participants as able to test alone. Among FS users (n = 100), observers noted frequent errors, most commonly related to blood collection and delivery. We found suggestive evidence (not reaching statistical significance) that user errors decreased, with 37.5%, to 28.1%, and 18.2% committing errors in phases I, II, and III, respectively (p-value:0.08), however observer concerns remained constant. Ease and confidence using HIVST increased with HIV testing experience. Participants using three HIVST were more likely (RR:1.92, 95% CI:1.32, 2.80) to report ease compared to those without prior HIVST experience. Never testers (RR:0.66, 95% CI:0.44-0.99) reported less ease performing HIVST compared to participants testing in the past six months. CONCLUSIONS: MSM were able to perform the OF test. Fingerstick test performance was less consistent; however preference for fingerstick was strong and performance may improve with exposure and instructional resources. Continued efforts to provide accessible instructions are paramount.
