Implementation preferences for the management of sexually transmitted infections in the South African health system: a discrete choice experiment.

OBJECTIVES: Despite strengthening HIV prevention with the introduction of pre-exposure prophylaxis (PrEP), STI services have remained relatively unchanged and the standard of care remains syndromic management. We used a discrete choice experiment to investigate service users' preferences for the diagnosis and treatment of STIs in South Africa. METHODS: Between 1 March 2021 and 20 April 2021, a cross-sectional online questionnaire hosted on REDCap was administered through access links sent to WhatsApp support groups for HIV PrEP users and attendees of two primary healthcare clinics and two mobile facilities in the Eastern Cape and Gauteng provinces aged between 18 and 49 years. Participants either self-completed the questionnaire or received support from a research assistant. We used a conditional logit model for the initial analysis and latent class model (LCM) to establish class memberships, with results displayed as ORs and probabilities. RESULTS: We enrolled 496 individuals; the majority were female (69%) and <30 years (74%). The LCM showed two distinct groups. The first group, comprising 68% of the participants, showed a strong preference for self-sampling compared with no sampling (OR 2.16, 95% CI 1.62 to 2.88). A clinic follow-up appointment for treatment was less preferable to same-day treatment (OR 0.78, 95% CI 0.63 to 0.95). Contact slip from index patient (OR 0.86, 95% CI 0.76 to 0.96) and healthcare professional (HCP)-initiated partner notification (OR 0.63, 95% CI 0.55 to 0.73) were both less preferable than expedited partner treatment (EPT). The second group included 32% of participants with a lower preference for self-sampling compared with no sampling (OR 0.65, 95% CI 0.41 to 1.04). There was no treatment option that was significantly different from the others; however, there was a strong preference for HCP-initiated partner notification to EPT (OR 1.53, 95% CI 1.10 to 2.12). CONCLUSIONS: Our results suggest that service users preferred STI testing prior to treatment, with the majority preferring self-taken samples and receiving aetiology-based treatment on the same day.

Comparing the Integration of Syndromic versus Etiological Management of Sexually Transmitted Infections Into HIV Pre-Exposure Prophylaxis Services for Adolescent Girls and Young Women, in South Africa.

South Africa has a high incidence of human immunodeficiency virus and sexually transmitted infections (STIs), particularly among adolescent girls and young women. National and global guidelines recommend varied strategies for integrating STI and pre-exposure prophylaxis (PrEP) services. PURPOSE: This paper describes the implementation of a syndromic compared to an etiological approach to STI integration within PrEP services in South Africa. METHODS: We analysed program data from eight fixed and four mobile clinics to describe a cascade of STI care and integration of syndromic management among clients accessing PrEP services. Diagnostic testing was conducted in a subset of clients to determine the prevalence of STIs and estimate the burden of disease missed using a syndromic approach. RESULTS: Between December 2018 and December 2021, 22,505 clients sought services and a high proportion (92.9%) was screened for STI symptoms. Of these, 9% of females and 3% of males had symptoms and 89.5% had recorded treatment. In a subset of PrEP clients (406 females, 70 males) screened through laboratory testing, chlamydia was identified in 25.7% of female and 20.0% of male samples, gonorrhea in 14.1% of female and 18.6% of male samples, and syphilis in 2.3% of female and 1.4% of male samples. Highest prevalence was found among females aged 18-20 years. DISCUSSION: Syndromic STI screening and management can be integrated into routine PrEP service delivery and can identify symptomatic STIs, but misses asymptomatic infections. PrEP clients have a high prevalence of treatable STIs. Etiologic approaches can identify more infections than syndromic screening, but cheap point-of-care tests are needed.

Mental Health Needs of Adolescent and Young Adult PrEP Users in South Africa: Implications for Sexual and Reproductive Health Programming.

PURPOSE: Poor mental health is associated with sexual and reproductive health (SRH) risks, including human immunodeficiency virus (HIV) and pre-exposure prophylaxis discontinuation. Adolescents and young people (AYP) are vulnerable to HIV and depression. This paper describes the prevalence and severity of depression and associated factors in AYP accessing SRH services in South Africa. METHODS: A cross-sectional analysis of enrollment data (January 2019 to December 2021) from a cohort of individuals receiving pre-exposure prophylaxis services at eight clinics in three provinces in South Africa was conducted. Females (n = 1,074) and males (n = 231) aged 15-24 years were included. Interviewer-administered questionnaires were conducted, and the prevalence and severity of depression assessed using the Patient Health Questionnaire-9. Multivariate analysis was used to identify factors associated with depression. RESULTS: Over 40% of participants had experienced any depression symptoms (43.7% of females, 38.5% of males). For males, experiencing intimate partner violence was the only predictor of depression symptoms (adjusted odds ratio (AOR) 8.81, 95% confidence intervals (CI) 1.03-75.44). For females, living with both parents (AOR 1.70, 95% CI 1.15-2.51), having transactional sex (AOR 1.63, 95% CI 1.00-2.65), experiencing any intimate partner violence (AOR 1.96, 95% CI 1.34-2.89), and using drugs (AOR 1.78, 95% CI 1.03-3.11) were all positively associated with depression symptoms. Resilience was a protective factor against depression symptoms for both sexes (males: AOR 0.96, 95% CI 0.93-0.98; females: AOR 0.96, 95% CI 0.95-0.97). DISCUSSION: There is a high burden of depression among AYP accessing SRH services in South Africa. Mental health screening should be integrated into SRH and HIV prevention programs for AYP.

Patterns of HIV Pre-exposure Prophylaxis use Among Adolescent Girls and Young Women Accessing Routine Sexual and Reproductive Health services in South Africa.

PURPOSE: This study describes the patterns of pre-exposure prophylaxis (PrEP) use among adolescent girls and young women (AGYW) initiated on daily oral PrEP for the prevention of HIV, within routine sexual and reproductive health services in South Africa. METHODS: We analysed clinical and survey data from a nested cohort of 967 AGYW initiated on oral PrEP between January 2019 and December 2021 in four geographical clusters in South Africa. We describe the periods of PrEP use, and the proportion who discontinued and subsequently restarted PrEP. Logistic regression analyses were conducted to determine factors associated with early PrEP discontinuation, PrEP use for ≥4 months and PrEP restart. RESULTS: PrEP use for ≤1 month was high (68.6%), although 27% returned and restarted PrEP; and 9% restarted more than once. Initiating PrEP at a mobile clinic (AOR 2.10, 95% CI 1.51 - 2.93) and having a partner known to be HIV negative or whose HIV status was unknown (AOR 7.11, 95% CI 1.45 - 34.23; AOR 6.90, 95% CI 1.44 - 33.09) were associated with PrEP use for ≤1 month. AGYW receiving injectable contraceptives were more likely to restart PrEP (AOR 1.61, 95% CI 1.10 - 2.35). Compared to those aged 15-17 years, participants 18 - 20 and 21 - 24 years were less likely to restart PrEP (AOR 0.51, 95% CI 0.35 - 0.74; AOR 0.60, 95%, CI 0.41 - 0.87), as were those initiating PrEP at a mobile clinic compared to a fixed facility (AOR 0.66, 95% CI 0.47 - 0.92). DISCUSSION: Although early PrEP discontinuation was high, it appears that PrEP use is frequently cyclical in nature. Further research is needed to determine if these cycles of PrEP correlate to periods of perceived or actual vulnerability to HIV, which may also be cyclical. PrEP delivery presents a unique opportunity to address multiple unmet health needs of young people.

The Use of HIV Pre-exposure Prophylaxis Among Men Accessing Routine Sexual and Reproductive Health Services in South Africa.

PURPOSE: This study describes a cohort of men seeking oral pre-exposure prophylaxis (PrEP) services and explores their patterns of PrEP use within an implementation project seeking to integrate PrEP provision within sexual and reproductive health services in public health clinics in South Africa. METHODS: Routine program and survey data from 364 males initiated on oral PrEP between July 2020 and May 2022 were analyzed. PrEP use was examined, including time to first discontinuation and restart patterns. Factors associated with early PrEP discontinuation and PrEP restart were analyzed. RESULTS: Despite primarily focusing on access for adolescent girls and young women, PrEP services reached males with HIV prevention needs. PrEP use for ≤1 month (early discontinuation) was high at 58%; however, 18% restarted on PrEP, with 4% restarting repeatedly. Having depression symptoms was associated with early PrEP discontinuation (adjusted odds ratio [AOR]: 1.71, 95% CI [confidence interval]: 1.06-2.78). Those ≥25 years were less likely to discontinue early, as were those with a partner treated for a sexually transmitted infection in the preceding three months (AOR: 0.33, 95% CI: 0.13-0.84) and those who had been circumcised (AOR: 0.59, 95% CI: 0.36-0.96). Those 18-20 years old were less likely to restart PrEP than those ≥25 years (AOR: 0.43, 95% CI: 0.19-0.97), as were those whose partner's HIV status was unknown (AOR: 0.33, 95% CI: 0.12-0.88). DISCUSSION: This study identified interest and uptake of oral PrEP among an underrepresented population of predominantly heterosexual males seeking sexual and reproductive health services. It found high rates of early PrEP discontinuation, with a subset returning to restart PrEP. Further research is needed to determine whether these periods of PrEP use are associated with periods of HIV risk.

A systematic review of antimicrobial resistance in Neisseria gonorrhoeae and Mycoplasma genitalium in sub-Saharan Africa.

OBJECTIVES: Limited antimicrobial resistance (AMR) surveillance coupled with syndromic management of sexually transmitted infections (STIs) in sub-Saharan Africa (SSA) could be contributing to an increase in AMR in the region. This systematic review aimed to synthesize data on the prevalence of AMR in common STIs in SSA and identify some research gaps that exist. METHODS: We searched three electronic databases for studies published between 1 January 2000 and 26 May 2020. We screened the titles and abstracts for studies that potentially contained data on AMR in SSA. Then we reviewed the full text of these studies to identify articles that reported data on the prevalence of AMR in Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis and Mycoplasma genitalium in SSA. We summarized the data using a narrative synthesis. RESULTS: The 40 included studies reported on AMR data from 7961 N. gonorrhoeae isolates from 15 countries in SSA and 350 M. genitalium specimens from South Africa. All four SSA regions reported very high rates of ciprofloxacin, tetracycline and penicillin resistance in N. gonorrhoeae. Resistance to cefixime or ceftriaxone was observed in all regions except West Africa. Azithromycin resistance, recommended as part of dual therapy with an extended-spectrum cephalosporin for gonorrhoea, was reported in all the regions. Both macrolide and fluoroquinolone-associated resistance were reported in M. genitalium in South Africa. Studies investigating AMR in C. trachomatis and T. vaginalis were not identified. CONCLUSIONS: There is a need to strengthen AMR surveillance in SSA for prompt investigation and notification of drug resistance in STIs.
