- Abstract
Sexually transmitted infections (STIs) are widespread worldwide and negatively affect sexual and reproductive health. Gaps in evidence and in available tools have long hindered STI programmes and policies, particularly in resource-limited settings. In 2022, WHO initiated a research prioritisation process to identify the most important STI research areas to address the global public health need. Using an adapted Child Health and Nutrition Research Initiative methodology including two global stakeholder surveys, the process identified 40 priority STI research needs. The top priorities centred on developing and implementing affordable, feasible, rapid point-of-care STI diagnostic tests and new treatments, especially for gonorrhoea, chlamydia, and syphilis; designing new multipurpose prevention technologies and vaccines for STIs; and collecting improved STI epidemiologic data on both infection and disease outcomes. The priorities also included innovative programmatic approaches, such as new STI communication and partner management strategies. An additional six research areas related to mpox (formerly known as monkeypox) reflect the need for STI-related research during disease outbreaks where sexual transmission can have a key role. These STI research priorities provide a call to action for focus, investment, and innovation to address existing roadblocks in STI prevention, control, and management to advance sexual and reproductive health and wellbeing for all., Competing Interests: Declaration of interests SLG received support from the Bill & Melinda Gates Foundation paid to WHO for work on therapeutic human papillomavirus vaccines and on COVID-19 vaccines and pregnancy, and the Gates Foundation travel support to meetings on maternal immunisation and women's health innovations.

- Abstract
Accurate and user-friendly rapid point-of-care diagnostic tests (POCT) are needed to optimize treatment of Neisseria gonorrhoeae, especially in low-resource settings where syndromic management is the standard of care for sexually transmitted infections. This study aimed to assess the acceptability and usability of a novel lateral flow assay and portable reader for the point-of-care detection of N. gonorrhoeae infection (NG-LFA). This mixed-methods study was conducted as part of a diagnostic performance and usability evaluation of a prototype NG-LFA for detection of N. gonorrhoeae in symptomatic men and women at primary healthcare facilities in the Buffalo City Metro, South Africa. The Standardized System Usability Scale (SUS) was administered, and in-depth interviews were conducted among healthcare professionals (HCPs) and fieldworkers (FWs) at pre-implementation, initial use and 3- and 6-month study implementation to assess user expectations, practical experience, and future implementation considerations for the NG-LFA. Data collection and analysis was guided by the Health Technology Adoption Framework, including new health technology attributes, learnability, satisfaction, and suitability. The framework was adapted to include perceived durability. A total of 21 HCPs and FWs were trained on the NG-LFA use. SUS scores showed good to excellent acceptability ranging from 78.8-90.6 mean scores between HCPs and FWs across study time points. All transcripts were coded using Dedoose and qualitative findings were organized by learnability, satisfaction, suitability, and durability domains. Usability themes are described for each time point. Initial insecurity dissipated and specimen processing dexterity with novel POCT technology was perfected over time especially amongst FWs through practical learning and easy-to-use instructions (learnability). Participants experienced both positive and negative test results, yielding perceived accuracy and minimal testing challenges overall (satisfaction). By 3- and 6-month use, both HCPs and FWs found the NG-LFA convenient to use in primary health care facilities often faced with space constraints and outlined perceived benefits for patients (suitability and durability). Findings show that the NG-LFA device is acceptable and usable even amongst paraprofessionals. High SUS scores and qualitative findings demonstrate high learnability, ease-of-use and suitability that provide valuable information for first-step scale-up requirements at primary healthcare level. Minor prototype adjustments would enhance robustness and durability aspects., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 de Vos et al.

- Abstract
Objectives: Globally, there have been significant changes in utilisation of STI testing and treatment services during the period of the COVID-19 pandemic. The impact of COVID-19 in countries that use syndromic STI management is not documented. This study used routine STI surveillance data to evaluate the impact of COVID-19 on utilisation of STI syndromic management services during the first wave of the COVID-19 epidemic in South Africa., Methods: We conducted a time-trend analysis of male urethritis syndrome (MUS) cases reported through routine national STI surveillance in South Africa and COVID-19 data available through the national dashboard. We defined three time periods (prelockdown, lockdown and postlockdown) based on COVID-19 response levels. Trends in MUS reporting was compared between these time periods at national and provincial level and with the number of positive COVID-19 tests in a district., Results: An overall reduction of 27% in the national number of MUS cases reported (monthly average from 27 117 to 20 107) occurred between the pre-COVID-19 and COVID-19 lockdown periods (p<0.001), with a range of 18%-39% between the nine provinces. Postlockdown, case numbers returned almost to the prelockdown level (26 304; -3.0%). No significant difference was found in number of MUS cases between the prelockdown and postlockdown periods. A weak correlation (R
2 =0,21) was identified between the change in number of MUS reported and COVID-19 positive tests in a district., Conclusions: A strong reduction in reported MUS cases for syndromic management was observed during the first wave of the COVID-19 epidemic and lockdown across all provinces in South Africa. This is likely the result of various healthcare system and service delivery factors associated with lockdown measures. The observed return of MUS cases reported to prelockdown measures is reassuring., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

- Abstract
Background: Vaginal discharge syndrome (VDS) is a common condition. Clinical management targets sexually transmitted infections (STIs) and bacterial vaginosis (BV); there is limited focus on Candida infection as cause of VDS. Lack of Candida treatment coverage and, if present, antifungal resistance may result in VDS treatment failure. This study aimed to determine the prevalence of Candida infection, antifungal resistance, and coinfections in Namibian women with VDS., Methods: A cross-sectional study was performed using 253 vaginal swabs from women with VDS in Namibia. Demographic data was collected, and phenotypic and molecular detection of Candida species was performed followed by fluconazole susceptibility testing of Candida isolates. BV was diagnosed using Nugent score microscopy; molecular detection of Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis was performed., Results: Candida species was detected in 110/253 women (43%). Ninety women (36%) had Candida albicans and 24 (9.5%) had non-albicans Candida species. The non-albicans species detected were 19 (17%) Candida glabrata, 4.0 (3.5%) Candida krusei, and 1.0 (0.9%) Candida parapsilosis. Candida albicans were more frequently isolated in younger (p = 0.004) and pregnant women (p = 0.04) compared to non-albicans Candida species. Almost all (98%) Candida albicans isolates were susceptible to fluconazole while all non-albicans Candida species were fluconazole resistant. STIs were diagnosed in 92 women (36%): 30 (12%) with C. trachomatis, 11 (4.3%) N. gonorrhoeae, and 70 (28%) T. vaginalis; 98 (39%) women had BV. Candida infection alone was diagnosed in 30 women (12%), combined with STIs in 42 women (17%) and was concurrent with BV in 38 women (15%). Candida infection was more often detected in swabs from women without C. trachomatis detected (6.4% vs. 16%; OR 0.30; 95% CI 0.10-0.77, p = 0.006)., Conclusions: The high prevalence of Candida infection, especially those due to non-albicans Candida species that are resistant to fluconazole, is a great concern in our setting and may lead to poor treatment outcomes. Access to microbiological testing for Candida species in the context of syndromic management is warranted., (© 2022. The Author(s).)

- Abstract
Background: Sexually transmitted infections (STIs) during pregnancy are associated with adverse birth outcomes, including preterm birth, low birth weight, perinatal death, and congenital infections such as increased mother-to-child HIV transmission. Prevalence of STIs among pregnant women in South Africa remains high, with most women being asymptomatic for their infection(s). Unfortunately, most STIs remain undetected and untreated due to standard practice syndromic management in accordance with World Health Organization (WHO) guidelines. Although lab-based and point-of-care molecular tests are available, optimal screening strategies during pregnancy, their health impact, and cost-effectiveness are unknown., Methods: We will implement a 3-arm (1:1:1) type-1 hybrid effectiveness-implementation randomized-controlled trial (RCT). We will enroll 2500 pregnant women attending their first antenatal care (ANC) visit for their current pregnancy at participating health facilities in Buffalo City Metro District, Eastern Cape Province, South Africa. Participants allocated to arms 1 and 2 (intervention) will receive GeneXpert® point-of-care diagnostic testing for Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis, with same-day treatment for detected infection(s). Arm 1 will additionally receive a test-of-cure 3 weeks post-treatment, while Arm 2 will receive a repeat test at 30-34 weeks' gestation. Those allocated to Arm 3 will receive syndromic management (standard-of-care). The RE-AIM framework will be used to guide collection of implementation indicators to inform potential future scale up. Primary outcome measures include (1) frequency of adverse birth outcomes among study arms, defined by a composite measure of low birth weight and pre-term delivery, and (2) change in STI prevalence between baseline and birth outcome among intervention arms and compared to standard-of-care. Estimates and comparative costs of the different screening strategies relative to standard-of-care and the costs of managing adverse birth outcomes will be calculated. Cost-effectiveness will be assessed per STI and disability-adjusted life year averted., Discussion: This trial is the first RCT designed to identify optimal, cost-effective screening strategies that decrease the burden of STIs during pregnancy and reduce adverse birth outcomes. Demonstrating the impact of diagnostic screening and treatment, compared to syndromic management, on birth outcomes will provide critical evidence to inform changes to WHO guidelines for syndromic management of STIs during pregnancy., Trial Registration: ClinicalTrials.gov NCT04446611 .

- Abstract
Background: Sexually transmitted infections (STIs) during pregnancy may increase the risk of adverse pregnancy outcomes. STI syndromic management is standard of care in South Africa but has its limitations. We evaluated the impact of diagnosing and treating curable STIs during pregnancy on adverse pregnancy and birth outcomes., Methods: We combined data from two prospective studies of pregnant women attending public sector antenatal care (ANC) clinics in Tshwane District and Cape Town, South Africa. Pregnant women were enrolled, tested and treated for STIs. We evaluated the association between any STI at the first ANC visit and a composite adverse pregnancy outcome (miscarriage, stillbirth, preterm birth, early neonatal death, or low birthweight) using modified Poisson regression models, stratifying by HIV infection and adjusting for maternal characteristics., Results: Among 619 women, 61% (n = 380) were from Tshwane District and 39% (n = 239) from Cape Town; 79% (n = 486) were women living with HIV. The prevalence of any STI was 37% (n = 228); C. trachomatis, 26% (n = 158), T. vaginalis, 18% (n = 120) and N. gonorrhoeae, 6% (n = 40). There were 93% (n = 574) singleton live births, 5% (n = 29) miscarriages and 2% (n = 16) stillbirths. Among the live births, there were 1% (n = 3) neonatal deaths, 7% (n = 35) low birthweight in full-term babies and 10% (n = 62) preterm delivery. There were 24% (n = 146) for the composite adverse pregnancy outcome. Overall, any STI diagnosis and treatment at first ANC visit was not associated with adverse outcomes in women living with HIV (adjusted relative risk (aRR); 1.43, 95% CI: 0.95-2.16) or women without HIV (aRR; 2.11, 95% CI: 0.89-5.01). However, C. trachomatis (aRR; 1.57, 95% CI: 1.04-2.39) and N. gonorrhoeae (aRR; 1.69, 95% CI: 1.09-3.08), were each independently associated with the composite adverse outcome in women living with HIV., Conclusion: Treated STIs at the first ANC visit were not associated with adverse pregnancy outcome overall. In women living with HIV, C. trachomatis or N. gonorrhoeae at first ANC were each independently associated with adverse pregnancy outcome. Our results highlights complex interactions between the timing of STI detection and treatment, HIV infection and pregnancy outcomes, which warrants further investigation., (© 2022. The Author(s).)

- Abstract
Objective: STIs during pregnancy increase adverse pregnancy and birth outcomes and may increase HIV risk. STI syndromic management is standard of care in South Africa. Our study evaluated the prevalence and incidence of STIs in pregnant women and the associated risk factors., Methods: We combined data from two prospective observational studies of pregnant women enrolled while attending their first antenatal clinic (ANC) visit in Tshwane District and Cape Town. Women ≥18 years were tested at first ANC visit and at their first postpartum visit for Chlamydia trachomatis , Neisseria gonorrhoeae and Trichomonas vaginalis using Xpert assays (Cepheid, USA). We evaluated the prevalence and incidence of STI and the associated risk factors using multivariable regression models., Results: We enrolled 669 pregnant women, 64% (n=427) from Tshwane District and 36% (n=242) from Cape Town; 80% (n=534) were women living with HIV (WLHIV) and 20% (n=135) without HIV. At enrolment, 37% (n=250) were diagnosed with at least one STI, of which 76% (n=190) were asymptomatic. STI prevalence was 40% (n=213) in WLHIV and 27% (n=37) in women without HIV (p=0.01). Baseline STI infection was associated with younger age (OR=0.95 per year, 95% CI 0.92 to 0.98), higher gestational age (adjusted OR (aOR)=1.03 per week, 95% CI 1.00 to 1.05), single relationship status (aOR=1.53, 95% CI 1.09 to 2.15) and HIV status (aOR=1.86, 95% CI 1.17 to 2.95). Of 419 participants with no STI at baseline, 21 had an incident STI during follow-up, with a mean follow-up time of 140 days. The incidence rate of STI during pregnancy and early post partum was 15 infections per 100 women-years (95% CI 9 to 23). Younger age was associated with STI incidence., Conclusion: Our study shows high prevalence and incidence of STIs in pregnancy, especially in WLHIV, demonstrating the need for STI screening in ANC to prevent adverse pregnancy and birth outcomes. Most STI cases were asymptomatic and would have gone untreated with syndromic management. Aetiological STI screening is urgently needed to reduce the burden of STIs in pregnancy., Competing Interests: Competing interests: The authors received a donation of STI Xpert assays from Cepheid (California, USA)., (© Author(s) (or their employer(s)) 2021.

- Abstract
Objectives: To determine the unmet need for care and barriers for consulting sexually transmitted infection (STI) services at six primary healthcare (PHC) facilities in rural South Africa., Methods: Cross-sectional study using three community-based strategies to mobilise adult individuals with STI-associated symptoms to access care. Participants were mobilised through clinic posters and referral by community healthcare workers (CHWs) and traditional leaders after training. Men with male urethritis syndrome and women with vaginal discharge syndrome were mobilised to visit participating PHC facilities on two designated days when an expert team visited the facility. Questionnaires were completed and HIV rapid tests offered. The minimal unmet need for care of individuals with STI-associated symptoms was calculated by dividing the number of cases over the adult catchment population of each PHC facility., Results: We successfully mobilised 177 symptomatic individuals: 134 (76%) women and 43 (24%) men. The estimated minimal unmet need for STI care was 1:364 (95% CI 1:350-1:380) individuals in this region; the rate was higher in village than township facilities, and among women. Mobilisation through clinic posters (57%) and by CHWs (23%) was most successful. Three-quarters of individuals (132/177) reported symptoms that had been present for >30 days; 49% (87/177) had symptoms >6 months. In addition, we identified 14 individuals with untreated HIV infection amounting to a 7% HIV testing yield. Lack of awareness of symptoms (34%), and disappointment in care due to persistent (23%) or recurrent (15%) symptoms after previous treatment, or disappointment with health services in general during previous visit(s) for any reason (10%) was the most common reasons for not consulting health care., Conclusions: We demonstrate a high unmet need for care of individuals with STI-associated symptoms in rural South Africa that requires urgent attention. A multidisciplinary approach that creates service demand through community awareness and information provision by healthcare workers combined with strengthening the quality of STI services is required to improve reproductive health and prevent complications of untreated STIs in this population., (© 2019 John Wiley & Sons Ltd.)

- Abstract
Background: The burden of sexually transmitted infections (STIs) in areas of sub-Saharan Africa with poor access to health care services is not well documented. In remote areas of South Africa, we investigated the prevalence of STIs and approaches to providing STI services through a mobile clinic., Methods: We recruited 251 adult women visiting a mobile clinic that normally provides general health education and screening services, but not STI care. Clinical and sexual history was obtained and vaginal specimens were tested for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and Mycoplasma genitalium infection and for Candida albicans and bacterial vaginosis., Results: Laboratory test was positive for 133 (53%) of 251 women for at least 1 STI: C. trachomatis was observed in 52 (21%) women, N. gonorrhoeae in 39 (16%) women, T. vaginalis in 81 (32%) women and M. genitalium in 21 (8%) women. Eighty-one (32%) women met the criteria for vaginal discharge syndrome, of which 58% (47/81) would have been treated accurately. Among asymptomatic women 84 (49%) of 170 were diagnosed with an STI but untreated under the syndromic approach. We could not identify factors associated with asymptomatic STI infection., Conclusions: There is a high unmet need for STI care in rural South African settings with poor access to health care services. Provision of STI services in a mobile clinic using the syndromic management approach provides a useful approach, but would have to be enhanced by targeted diagnostics to successfully address the burden of infection.

- Abstract
Background: Sexual behaviors in human immunodeficiency virus (HIV)-infected pregnant women in South Africa are not well understood., Methods: Human immunodeficiency virus-infected pregnant women were recruited into a prospective cohort at first antenatal care visit. Sociodemographic information and self-collected vulvovaginal swab samples were collected from participants. Vulvovaginal swab samples were tested for Chlamydia trachomatis, Neisseria gonorrhoea, and Trichomonas vaginalis using GeneXpert. We investigated sexual behaviors, alcohol use, factors associated with condomless sex during pregnancy, and prevalent sexually transmitted infection (STI) among our cohort. We report descriptive, univariate and multivariable logistic regression results of sexual behaviors and alcohol use, factors associated with condomless sex at last sex, and having any STI during pregnancy adjusting for a priori confounders., Results: We recruited and enrolled 430 HIV-infected pregnant women. Median age was 30 years; median gestational age was 20 weeks. Eighty-nine percent of women reported sex during pregnancy. At last sex, 68% reported condomless sex; 18% reported having more than 1 sex partner in the past 12 months. Adjusting for age, income and relationship status, condom use at last sex was associated with prior knowledge of HIV status (adjusted odds ratio [aOR], 2.46; 95% confidence interval [CI], 1.54-3.92) and being in a concordant HIV-positive (aOR, 3.17; 95% CI, 1.84-5.50), or serodiscordant relationship (aOR, 6.50; 95% CI, 3.59-11.80). The prevalence of any STI was 41% (95% CI, 36%-45%). Adjusting for mothers' age and employment, odds of having an STI increased if the woman reported alcohol use during pregnancy (aOR, 1.96; 95% CI, 1.06-3.64) or if the father of the child was a non-cohabiting or casual partner (aOR, 1.42; 95% CI, 0.97-2.03)., Conclusions: Almost all HIV-infected pregnant women were sexually active during pregnancy and most women reported condomless sex at last sex. Condom use was associated with knowledge of serostatus and/or partner's serostatus before first antenatal care visit. Factors associated with having STIs included: alcohol use during pregnancy and father of child being a non-cohabiting partner.

- Abstract
Background: Trichomonas vaginalis is a sexually transmitted infection associated with increased transmission of HIV and significant adverse birth outcomes; culture and polymerase chain reaction (PCR) are commonly used in diagnosis., Methods: Consenting HIV-infected pregnant women were recruited from clinics in South Africa and screened for T. vaginalis using PCR. Polymerase chain reaction-positive women provided an additional sample for culture. We compared T. vaginalis detection between PCR and culture, and investigated how PCR cycle threshold (Ct) values differ among culture results., Results: A total of 359 women were enrolled and 76 (20%) tested T. vaginalis PCR positive. Cultures were obtained from 61 of the PCR-positive women, and 38 (62%) were culture positive. The median baseline Ct of the PCR-positive/culture-positive group was 22.6 versus 38.0 among those who were PCR positive/culture negative (P < 0.001). Culture-positive cases had lower Ct values (higher DNA load); a Ct value less than 30 predicted positivity with a sensitivity of 97% and a specificity of 96%., Conclusions: Culture was positive in roughly half of PCR-positive cases. The culture-negative cases had significantly higher Ct values, indicating a lower concentration of T. vaginalis DNA. A Ct value of 30 provides a reliable threshold for predicting culture positivity. The clinical significance of culture-negative infections detected by PCR is still unclear.

- Abstract
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.
