Sexually transmitted infection screening, prevalence and incidence among South African men and transgender women who have sex with men enrolled in a combination HIV prevention cohort study: the Sibanye Methods for Prevention Packages Programme (MP3) project

Reducing stigma and promoting HIV wellness/mental health of sexual and gender minorities: RCT results from a group-based programme in Nigeria

INTRODUCTION

High levels of HIV stigma as well as stigma directed towards sexual and/or gender minorities (SGMs) are well documented in the African setting. These intersecting stigmas impede psychosocial wellbeing and HIV prevention and care. Yet, there are few if any evidence-based interventions that focus on reducing internalized stigma and promoting mental health and HIV wellness for SGMs in Africa. We developed and evaluated a group-based intervention drawing on cognitive behavioural therapy (CBT) strategies for men who have sex with men (MSM) and transgender women (TGW) at risk for or living with HIV in Lagos, Nigeria.

METHODS

The intervention comprised four weekly in-person group sessions facilitated by community health workers. We conducted a delayed intervention group randomized controlled trial (April-September 2022), with pre-post surveys plus 3-month follow-up (immediate group only), as well as qualitative research with participants and programme staff. Outcomes included internalized stigma related to SGM and HIV status, depression, resiliency/coping and pre-exposure prophylaxis (PrEP)/HIV treatment use.

RESULTS

Mean age of the 240 participants was 26 years (range 18-42). Seventy-seven percent self-identified as MSM and 23% TGW; 27% were people with HIV. Most (88%) participants attended all four sessions, and 98% expressed high intervention satisfaction. There was significant pre-post improvement in each psychosocial outcome, in both the immediate and delayed arms. There were further positive changes for the immediate intervention group by 3-month follow-up (e.g. in intersectional internalized stigma, depression). While baseline levels of ever-PrEP use were the same, 75% of immediate-group participants reported currently using PrEP at 3 months post-intervention versus 53% of delayed-group participants right after the intervention (p<0.01). Participants post-intervention described (in qualitative interviews) less self-blame, and enhanced social support and resilience when facing stigma, as well as motivation to use PrEP, and indicated that positive pre-intervention changes in psychosocial factors found in the delayed group mainly reflected perceived support from the study interviewers.

CONCLUSIONS

This study demonstrated the feasibility and acceptability of a group-based CBT model for MSM and TGW in Nigeria. There were also some indications of positive shifts related to stigma, mental health and PrEP, despite issues with maintaining the randomized design in this challenging environment.

Frequent chlamydia and gonorrhoea but very infrequent syphilis among men who have sex with men using HIV pre-exposure prophylaxis in West Africa

OBJECTIVES

Although oral pre-exposure prophylaxis (PrEP) for HIV is being rolled out in West Africa, data on sexually transmitted infections (STIs) in PrEP users are scarce. We assessed the prevalence, incidence and determinants of bacterial STIs in men who have sex with men (MSM) taking PrEP in Burkina Faso, Côte d'Ivoire, Mali and Togo.

METHODS

A prospective cohort study among MSM initiating PrEP as part of a comprehensive HIV prevention package was conducted between 2017 and 2021 in community-based clinics in the four study countries. Molecular screening for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) was performed at months 0, 6 and 12. Serological testing for syphilis was performed every 3 months over the first year of follow-up. Determinants of CT and/or NG incidence were identified using Poisson generalised linear mixed models.

RESULTS

A total of 598 participants with a median age of 24.7 years were included. Prevalence of CT and/or NG was 24.4% (95% CI 21.0 to 28.1), 22.4% (95% CI 18.4 to 26.8) and 29.0% (95% CI 24.2 to 34.1) at months 0, 6 and 12, respectively. The prevalence of syphilis ranged from 0.2% (95% CI 0.0 to 0.9) at month 0 to 0.8% (95% CI 0.2 to 2.4) at month 12. Ninety incident CT and/or NG infections occurred during a total follow-up time of 280.6 person-years (incidence rate 32.1 per 100 person-years, 95% CI 25.8 to 39.4). Three incident syphilis infections were detected during a total follow-up time of 459.7 person-years (incidence rate 0.7 per 100 person-years, 95% CI 0.1 to 1.9). CT and/or NG incidence was associated with condomless insertive anal sex (adjusted incidence rate ratio 1.96, 95% CI 1.04 to 3.71, p=0.038).

CONCLUSIONS

CT and NG were frequent but syphilis was very infrequent in MSM using HIV PrEP in West Africa. HIV programme managers should integrate STI services into PrEP programmes.

Southern African HIV Clinicians Society Guideline for the clinical management of syphilis

Syphilis, 'the great imitator', caused by Treponema pallidum infection, remains a complex and multifaceted disease with a rich history of clinical diversity. This guideline aims to be a comprehensive guide for healthcare workers in Southern Africa, offering practical insights into the epidemiology, pathogenesis, clinical manifestations, diagnostic testing, therapeutic principles, and public health responses to syphilis. Although the syphilis burden has declined over the years, recent data indicate a troubling resurgence, particularly among pregnant women and neonates. This guideline highlights the diagnostic challenges posed by syphilis, stemming from the absence of a single high-sensitivity and -specificity test. While treatment with penicillin remains the cornerstone of treatment, alternative regimens may be used for specific scenarios. We highlight the importance of thorough patient follow-up and management of sex partners to ensure optimal care of syphilis cases. In the context of public health, we emphasise the need for concerted efforts to combat the increasing burden of syphilis, especially within high-risk populations, including people living with HIV.

"I felt special!": a qualitative study of peer-delivered HIV self-tests, STI self-sampling kits and PrEP for transgender women in Uganda

INTRODUCTION

Peer delivery is a client-centred approach that could maximize the coverage and impact of HIV services for transgender women (TGW). We conducted qualitative interviews to examine how peer-delivered HIV self-testing (HIVST), sexually transmitted infection self-sampling (STISS) and oral pre-exposure prophylaxis (PrEP) influenced prevention choices among TGW and their intimate partners in Uganda.

METHODS

Within a cluster randomized trial of peer-delivered HIVST, STISS and PrEP among HIV-negative TGW (NCT04328025), we conducted 55 qualitative interviews with 30 TGW, 15 intimate partners and 10 TGW peers (August 2021-February 2022). TGW interviews explored: (1) HIV self-test and PrEP experiences; (2) HIVST with intimate partners; and (3) descriptions of self-sampling for STI testing. Partner interviews covered: (1) experiences with HIVST; (2) disclosure of HIV status to intimate partner; and (3) descriptions of sexual behaviours after testing. Peer interview topics included: (1) intervention delivery experiences; and (2) recommendations for peer-delivered HIV prevention services to TGW, including psychological support and coping strategies. Qualitative data were analysed using an inductive content analytic approach.

RESULTS

Peer-delivered combination prevention was valued by this group of TGW and their partners. (1) Peer services extended beyond delivering HIV/STI kits and PrEP refills to caring for individual health and wellbeing by providing stigma coping strategies. Peer psychosocial support empowered research participants to become "HIVST ambassadors," teach non-study TGW about self-testing and PrEP, and encourage linkage to care. (2) HIVST with intimate partners and mutual disclosure of HIV status strengthened partnered relationships. PrEP use after both partners tested HIV negative implied infidelity. (3) Self-sampling enabled TGW to take control of their STI testing and avoid the embarrassment of exposing their bodies. Privacy and confidentiality motivated the uptake of STI testing and treatment.

CONCLUSIONS

In this sample of TGW from Uganda, peer delivery of HIVST, STISS and PrEP refills benefitted individual prevention efforts and extended to a new linkage of TGW not engaged in care. Integrating peer services into differentiated PrEP delivery could increase HIV/STI test coverage and PrEP use in this vulnerable population.

Risk factors for sexually transmitted infections among men who have sex with men

BACKGROUND

Sexually transmitted infections (STIs) are a global public health concern and sub-Saharan Africa, has limited data on STIs in the men who have sex with men (MSM) population. Syndromic management has controversies for treating asymptomatic STIs (ASTIs).

AIM

The aim of this study was to describe the risk factors for STIs among MSM.

SETTING

This study was conducted in Tshwane North, Gauteng Province in South Africa.

METHODS

A cross-sectional quantitative design was employed using structured questionnaires, rapid plasma reagent test, from December 2021 to May 2022. Bivariate and multivariate analyses were used for statistical analysis.

RESULTS

A total of 200 MSM with the mean age of 27.6, standard deviations: 6.8 participated, and STIs prevalence was 66%, with 37% concurrent infections. Ureaplasma urealyticum was (24%), Mycoplasma hominis (23%), Chlamydia trachomatis (20%), Treponema pallidum (20%) and Neisseria gonorrhoeae (9%). The risk factors for acquisition of STI include having a new partner in the last month (OR = 1.68; CI: 0.98-3.13).

CONCLUSION

The prevalence of ASTIs is high. Serial and multiple sexual partners are the risk factors.Contribution: This study contributes to the body of knowledge of the burden of STIs among high-risk population.

Doxycycline post-exposure prophylaxis for sexually transmitted infections in South Africa

South Africa has a large burden of bacterial sexually transmitted infections (STIs) with high rates among men who have sex with men (MSM). Randomised controlled trials have recently demonstrated high effectiveness of doxycycline post-exposure prophylaxis (PEP) for prevention of bacterial STIs in MSM, with 70% - 85% reductions in Chlamydia trachomatis infection and syphilis, and approximately 50% reduction in Neisseria gonorrhoeae infection. Doxycycline PEP was not demonstrated to be effective in reducing C. trachomatis and N. gonorrhoeae infection among Kenyan cisgender women. Although no worrisome trends in antimicrobial resistance (AMR) were observed in the trials, important concerns remain about doxycycline PEP and AMR development in STIs, other pathogens, commensals, and the microbiome. Tetracycline resistance in N. gonorrhoeae is already widespread in South Africa, but emergence of AMR in other STIs would be concerning. Larger sample sizes of doxycycline PEP users with longer follow-up time are needed to understand the impact that doxycycline PEP may have on AMR at individual and population level. In this opinion article, we weigh the benefits of doxycycline PEP for prevention of bacterial STIs against the existing AMR concerns and data gaps in the South African context. Based on the current evidence, we conclude that it would be reasonable to offer doxycycline PEP to high-risk MSM on a case-by-case basis, provided that it is offered by experienced sexual health clinicians in settings that have access to diagnostic STI testing and ongoing AMR surveillance.

Integration of sexually transmitted infection and HIV pre-exposure prophylaxis services in sub-Saharan Africa: a scoping review

Background

Persons living in sub-Saharan Africa (SSA) face disproportionate risk from overlapping epidemics of HIV and bacterial sexually transmitted infections (STIs). Pre-exposure prophylaxis (PrEP) for prevention is gradually being scaled up globally including in several settings in SSA, which represents a key opportunity to integrate STI services with HIV pre-exposure prophylaxis (PrEP). However, there is limited literature on how to successfully integrate these services, particularly in the SSA context. Prior studies and reviews on STI and PrEP services have largely focused on high income countries.

Methods

We conducted a scoping review of prior studies of integration of STI and PrEP services in SSA. We searched PubMed, EMBASE, Cochrane, and CINAHL, in addition to grey literature to identify studies that were published between January 2012 and December 2022, and which provided STI and PrEP services in SSA, with or without outcomes reported. Citations and abstracts were reviewed by two reviewers for inclusion. Full texts were then retrieved and reviewed in full by two reviewers.

Results

Our search strategy yielded 1951 records, of which 250 were retrieved in full. Our final review included 61 reports of 45 studies. Most studies were conducted in Southern (49.2%) and Eastern (24.6%) Africa. Service settings included public health clinics (26.2%), study clinics (23.0%), sexual and reproductive care settings (23.0%), maternal and child health settings (8.2%), community based services (11.5%), and mobile clinics (3.3%). A minority (11.4%) of the studies described only syndromic STI management while most (88.6%) included some form of etiological laboratory STI diagnosis. STI testing frequency ranged from baseline testing only to monthly screening. Types of STI tested for was also variable. Few studies reported outcomes related to implementation of STI services. There were high rates of curable STIs detected by laboratory testing (baseline genitourinary STI rates ranged from 5.6-30.8% for CT, 0.0-11.2% for GC, and 0.4-8.0% for TV).

Discussion

Existing studies have implemented a varied range of STI services along with PrEP. This range reflects the lack of specific guidance regarding STI services within PrEP programs. However, there was limited evidence regarding implementation strategies for integration of STI and PrEP services in real world settings.

Sexually transmitted infections amongst men who have sex with men (MSM) in South Africa

There is limited data about bacterial STIs in MSM populations in sub-Saharan Africa. Our retrospective analysis used data from the HVTN 702 HIV vaccine clinical trial (October 2016 to July 2021). We evaluated multiple variables. Polymerase chain reaction testing was conducted on urine and rectal samples to detect Neisseria gonorrhoea (NG) and Chlamydia trachomatis (CT) every 6 months. Syphilis serology was conducted at month 0 and thereafter every 12 months. We calculated STI prevalence and the associated 95% confidence intervals until 24 months of follow-up. The trial enrolled 183 participants who identified as male or transgender female, and of homosexual or bisexual orientation. Of these, 173 had STI testing done at month 0, median age was 23 (IQR 20-25) years, with median 20.5 (IQR 17.5-24.8) months follow-up (FU). The clinical trial also enrolled and performed month 0 STI testing on 3389 female participants, median age 23 (IQR 21-27) years, median 24.8 (IQR 18.8-24.8) months FU and 1080 non-MSM males with a median age of 27 (IQR 24-31) years, median 24.8 (IQR 23-24.8) months FU. At month 0, CT prevalence was similar in MSM and females (26.0% vs 23.0%, p = 0.492) but was more prevalent in MSM compared to non-MSM males (26.0% vs 14.3%, p = 0.001). CT was the most prevalent STI among MSM at months 0 and 6 but declined from month 0 to month 6 (26.0% vs 17.1%, p = 0.023). In contrast, NG did not decline in MSM between months 0 and 6 (8.1% vs 7.1%, p = 0.680) nor did syphilis prevalence between months 0 and 12 (5.2% vs 3.8%, p = 0.588). Bacterial STI burden is higher in MSM compared to non-MSM males, and CT is the most prevalent bacterial STI amongst MSM. Preventive STI vaccines, especially against CT, may be helpful to develop.

Determining the screening frequency for sexually transmitted infections for people who use HIV pre-exposure prophylaxis: a systematic review and meta-analysis

OBJECTIVES

Although the World Health Organization recommends 'frequent' screening of sexually transmitted infections (STI) for people who use pre-exposure prophylaxis for HIV, there is no evidence for optimal frequency.

METHODS

We searched five databases and used random-effects meta-analysis to calculate pooled estimates of STI test positivity. We narratively synthesized data on secondary outcomes, including adherence to recommended STI screening frequency and changes in STI epidemiology.

RESULTS

Of 7477 studies, we included 38 for the meta-analysis and 11 for secondary outcomes. With 2-3 monthly STI screening, the pooled positivity was 0.20 (95% confidence interval [CI]: 0.15-0.25) for chlamydia, 0.17 (95% CI: 0.12-0.22) for gonorrhea, and 0.07 (95% CI: 0.05-0.08) for syphilis. For chlamydia and gonorrhea, the positivity was approximately 50% and 75% lower, respectively, in studies that screened 4-6 monthly vs 2-3 monthly. There was no significant difference in the positivity for syphilis in studies that screened 4-6 monthly compared to 2-3 monthly. Adherence of clients to recommended screening frequency varied significantly (39-94%) depending on population and country. Modeling studies suggest more frequent STI screening could reduce incidence.

CONCLUSION

Although more frequent STI screening could reduce delayed diagnoses and incidence, there remain significant knowledge gaps regarding the optimal STI screening frequency.

Les hommes bisexuels sont moins exposés au virus de l’immunodéficience humaine que les homosexuels exclusifs en Afrique subsaharienne

INTRODUCTION

In sub-Saharan Africa, as in the rest of the world, men who have sex with men (MSM) are at greater risk of HIV infection than the general population. Bisexuals are often perceived to be more at risk than exclusive gay men.

PURPOSE OF RESEARCH

We propose a review of epidemiological surveys conducted in sub-Saharan Africa since 2005 to provide an overview of knowledge on HIV exposure among gay/bisexual men.

RESULTS

We reviewed 355 publications and identified 62 measures of the association between bisexuality and HIV prevalence and 8 measures of the association between bisexuality and incidence. Except for 4 of 62 measures, the HIV prevalence observed among bisexuals was equal to or lower than that observed among exclusive gay men. In terms of incidence, all but one of the identified studies observed lower or equal HIV incidence among bisexuals. From a behavioural perspective, most studies found no difference in condom use. Bisexuals may have less frequent sex and consistently less receptive anal sex. They mainly started their sexual lives with men later, had fewer partners, and were less likely to know their HIV status.

CONCLUSIONS

Bisexuals are less likely to be at risk of HIV than exclusive gay men, partly because of behavioural differences. Prevention and treatment programs for MSM must take the specificities of bisexuals into account and design differentiated services.

A qualitative study of how stigma influences HIV services for transgender men and women in Nigeria

INTRODUCTION

Transgender men and women in Nigeria experience many barriers in accessing HIV prevention and treatment services, particularly given the environment of transphobia (including harassment, violence and discrimination) and punitive laws in the country. HIV epidemic control in Nigeria requires improving access to and quality of HIV services for key populations at high risk, including transgender men and women. We assessed how stigma influences HIV services for transgender people in Lagos, Nigeria.

METHODS

In-depth interviews (IDIs) and focus group discussions were conducted with transgender men (n = 13) and transgender women (n = 25); IDIs were conducted with community service organization (CSO) staff (n = 8) and healthcare providers from CSO clinics and public health facilities (n = 10) working with the transgender population in March 2021 in Lagos. Content analysis was used to identify how stigma influences transgender people's experiences with HIV services.

RESULTS AND DISCUSSION

Three main findings emerged. First, gender identity disclosure is challenging due to anticipated stigma experienced by transgender persons and fear of legal repercussions. Fear of being turned in to authorities was a major barrier to disclose to providers in facilities not affiliated with a transgender-inclusive clinic. Providers also reported difficulty in eliciting information about the client's gender identity. Second, respondents reported lack of sensitivity among providers about gender identity and conflation of transgender men with lesbian women and transgender women with being gay or men who have sex with men, the latter being more of a common occurrence. Transgender participants also reported feeling disrespected when providers were not sensitive to their pronoun of preference. Third, HIV services that are not transgender-inclusive and gender-affirming can reinforce stigma. Both transgender men and women spoke about experiencing stigma and being refused HIV services, especially in mainstream public health facilities, as opposed to transgender-inclusive CSO clinics.

CONCLUSIONS

This study highlights how stigma impedes access to appropriate HIV services for transgender men and women, which can have a negative impact along the HIV care continuum. There is a need for transgender-inclusive HIV services and competency trainings for healthcare providers so that transgender clients can receive appropriate and gender-affirming HIV services.

Factors associated with testing for HIV and other sexually transmitted infections in men who have sex with men and transgender women in Bangkok, Thailand

Background

Routine screening for HIV and other sexually transmitted infections (STIs) facilitates early diagnosis and treatment, thereby preventing morbidity and onward transmission. We estimated the prevalence of prior HIV/STI testing among men who have sex with men (MSM) and transgender women (TGW) in Bangkok, Thailand, and identified factors associated with prior testing.

Methods

Cross-sectional analyses were performed using data collected at enrollment into an HIV incidence cohort. From April to October 2017, MSM and TGW were enrolled if they were aged 18–35 years, reported anal intercourse with a male or TGW partner, and reported behavioral vulnerability to HIV. Participants answered questions about demographics, sexual behaviors, and lifetime HIV/STI testing history. Multivariable robust Poisson regression was used to estimate risk ratios (RRs) and 95% confidence intervals (CIs) for factors potentially associated with prior testing.

Results

Among 1,014 participants, 348 (34.3%) were TGW and the median age was 21.6 (interquartile range 20.0-24.8) years. Prior testing for HIV was reported by 421 (41.5%) and for other STIs by 268 (26.4%). HIV testing was more common among participants aged ≥ 22 years (RR 1.37 [95% CI 1.13–1.67]), with college education as compared to secondary or less (RR 1.37 [95% CI 1.08–1.72]), and who met male sexual partners online (RR 1.52 [95% CI 1.24–1.85]), but lower among participants attracted to both men and women as compared to men only (RR 0.64 [95% CI 0.51–0.81]) and who met male sexual partners in bars (RR 0.83 [95% CI 0.72–0.97]). Similar associations were observed with prior testing for other STIs, including increased testing among participants with college education (RR 1.52 [95% CI 1.11–2.09]) and who met male sexual partners online (RR 1.73 [95% CI 1.30–2.31]), but lower among participants attracted to both men and women (RR 0.70 [95% CI 0.51–0.96]) and who met male sexual partners in bars (RR 0.67 [95% CI 0.54–0.83]).

Conclusions

Despite behavioral vulnerability, prior testing for HIV and other STIs was uncommon. Online engagement strategies may be effectively reaching Thai MSM and TGW who meet sexual partners online, but new interventions are needed to encourage testing among younger, less educated, and bisexual MSM and TGW.

Limited syphilis testing for key populations in Zimbabwe: A silent public health threat

In this article, the authors discuss the problem of high prevalences of active syphilis amongst key populations (KPs) in Zimbabwe, in combination with low testing rates, partly because of a difficult legal and social environment for these populations. The article highlights the need to develop strategies to address the high prevalence of syphilis amongst KPs. The authors discuss requirements for addressing deficits in existing clinical services, predominantly primary care settings, in providing primary healthcare, including sexually transmitted infection (STI) management, to Zimbabwe’s KP communities and utility of point-of-care testing and self-testing and other innovations to improve testing uptake.

OUP accepted manuscript

Background

Sexually transmitted infections (STIs) affect individuals of all ages, but adolescent girls and young women are disproportionately affected. We examined the prevalence and factors associated with self-reported STIs (SR-STIs) among adolescent girls and young women in sub-Saharan Africa (SSA).

Methods

Demographic and Health Survey data of 27 sub-Saharan African countries were used for the study. The sample size comprised 68944 adolescent girls and young women (15–24 y of age). The outcome variable was SR-STIs. Multilevel binary logistic regression analysis was performed to identify factors associated with SR-STIs.

Results

On average, the prevalence of SR-STIs among adolescent girls and young women in SSA was 6.92%. The likelihood of SR-STIs was higher among young women aged 20–24 y (adjusted odds ratio [aOR] 1.36 [confidence interval {CI} 1.27 to 1.46]), those not married (aOR 1.64 [CI 1.51 to 1.79]), those working (aOR 1.20 [CI 1.12 to 1.27]), those whose age at first sex was ≤19 y (aOR 1.99 [CI 1.80 to 2.20]), those with two or more sex partners (aOR 1.56 [CI 1.35 to 1.80]), those who listened to radio (aOR 1.26 [CI 1.17 to 1.35]), those in urban areas (aOR 1.42 [CI 1.30 to 1.51]) and those with a wealth index of rich (aOR 1.28 [CI 1.17 to 1.40]) compared with their counterparts. In contrast, those with a primary (aOR 0.86 [CI 0.78 to 0.94]) or secondary/higher level of education (aOR 0.83 [CI 0.75 to 0.92]) compared with those with no formal education and those who were exposed to television (aOR 0.90 [CI 0.84 to 0.98]) compared with those who were not exposed were less likely to report STIs.

Conclusions

Our findings demonstrate the need for countries in SSA to commit towards reducing the incidence of STIs. Community-based health educational programs are required to intensify the awareness of STIs and their prevention in various sub-Saharan African countries considering the factors that expose adolescent girls and young women to STIs.

Acceptability and satisfaction towards self-collection for chlamydia and gonorrhoea testing among transgender women in Tangerine Clinic, Thailand: shifting towards the new normal

Introduction

Provider‐collected swabs are an unappealing procedure for many transgender women and may have led to suboptimal rates of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) testing. Self‐collection for CT/NG testing is recommended for men who have sex with men. However, the information on acceptability and clinical performance to support a recommendation for transgender women is lacking. We aimed to determine the acceptability and satisfaction towards self‐collection for CT/NG testing among Thai transgender women.

Methods

Thai transgender women who attended Tangerine Clinic (a transgender‐led, integrated, gender‐affirming care and sexual health services clinic in Bangkok, Thailand) between May and July 2020 and had condomless sexual intercourse within the past six months were offered to collect urine and perform self‐swabs of pharyngeal, rectal, and if applicable, neovaginal compartments for pooled nucleic acid amplification testing for CT/NG infections. Participants received a diagram, video and oral instructions about how to perform self‐collection procedure. Those who accepted self‐collection were also offered to receive provider collection to evaluate the performance between the two methods. Self‐administered questionnaires were used to assess satisfaction.

Results

Among 216 transgender women enrolled, 142 (65.7%) accepted self‐collection. All who accepted had pharyngeal, rectal and urine samples collected. Of 31 transgender women who had undergone genital surgery, 28 (90.3%) accepted neovaginal self‐swab. The acceptance rate increased from 46.2% in May to 84.5% in July 2020. One participant had an invalid result. All transgender women who accepted self‐collection could perform it without assistance, and 82.8% were highly satisfied with the method. None reported dissatisfaction. Due to the COVID‐19 pandemic, provider collection services were discontinued early, and only eight transgender women were able to perform both methods for performance evaluation. The performance agreement was 100%.

Conclusions

Thai transgender women had high acceptability and satisfaction towards self‐collection for CT/NG testing. The performance was promising compared to provider collection. Our results support the implementation of self‐collection to the sexually transmitted infection services, particularly during the COVID‐19 pandemic where physical distancing is the new normal. A larger study is warranted to determine the performance of self‐collection for CT/NG testing in each anatomical compartment and confirm the performance between self‐collection and provider collection.

Decrease in incidence of sexually transmitted infections symptoms in men who have sex with men enrolled in a quarterly HIV prevention and care programme in West Africa (CohMSM ANRS 12324-Expertise France)

OBJECTIVE

Although men who have sex with men (MSM) are at high risk of STI, their access to tailored healthcare services remains limited in West Africa. We assessed the change in STI symptoms incidence over time among MSM enrolled in a quarterly HIV prevention and care programme in four cities in Burkina Faso, Côte d'Ivoire, Mali and Togo.

METHODS

We performed a prospective cohort study in MSM followed up between 2015 and 2019. Men aged over 18 who reported anal sex with another man within the previous 3 months were offered quarterly syndromic diagnosis and treatment for STI, as well as HIV testing, peer-led counselling and support. Condoms and lubricants were also provided. The change in STI symptoms incidence during follow-up was investigated using a non-parametric trend test and mixed-effect Poisson regression models.

RESULTS

816 participants were followed for a total duration of 1479 person-years. 198 participants (24.3%) had at least one STI symptom during follow-up. Overall, STI symptoms incidence was 20.4 per 100 person-years (95% CI 18.4 to 22.6), ranging from 15.3 in Abidjan to 33.1 in Ouagadougou (adjusted incidence rate ratio (aIRR) 2.39, 95% CI 1.55 to 3.69, p<0.001). STI symptoms incidence was 16.8 and 23.0 per 100 person-years in HIV-positive and HIV-negative participants, respectively (aIRR 0.77, 95% CI 0.57 to 1.04, p=0.087). STI symptoms incidence decreased significantly from 29.9 per 100 person-years in the first 6 months to 8.6 at 30-35 months of follow-up (aIRR per 6-month increase 0.84, 95% CI 0.77 to 0.92, p<0.001).

CONCLUSION

STI symptoms incidence decreased over time but the overall burden of STI appeared to be very high in MSM followed up in West Africa. STI services including counselling, diagnosis and treatment should be reinforced. Laboratory tests that allow accurate diagnosis of STI are required. Strengthening STI services will be critical for controlling the HIV and STI epidemics in this vulnerable population and in the general population.
