Abstract
OBJECTIVE Sexually transmitted infections (STIs), including syphilis, chlamydia, gonorrhoea and trichomoniasis, are of global public health concern. While STI incidence rates in sub-Saharan Africa are high, longitudinal data on incidence and recurrence of STIs are scarce, particularly in rural areas. We determined the incidence rates of curable STIs in HIV-negative women during 96 weeks in a rural South African setting. METHODS We prospectively followed participants enrolled in a randomised controlled trial to evaluate the safety and efficacy of a dapivirine-containing vaginal ring for HIV prevention in Limpopo province, South Africa. Participants were included if they were female, aged 18-45, sexually active, not pregnant and HIV-negative. Twelve-weekly laboratory STI testing was performed during 96 weeks of follow-up. Treatment was provided based on vaginal discharge by physical examination or after a laboratory-confirmed STI. RESULTS A total of 119 women were included in the study. Prevalence of one or more STIs at baseline was 35.3%. Over 182 person-years at risk (PYAR), a total of 149 incident STIs were diagnosed in 75 (65.2%) women with incidence rates of 45.6 events/PYAR for chlamydia, 27.4 events/100 PYAR for gonorrhoea and 8.2 events/100 PYAR for trichomoniasis. Forty-four women developed ≥2 incident STIs. Risk factors for incident STI were in a relationship ≤3 years (adjusted hazard ratio [aHR]: 1.86; 95% confidece interval [CI]: 1.04-2.65) and having an STI at baseline (aHR: 1.66; 95% CI: 1.17-2.96). Sensitivity and specificity of vaginal discharge for laboratory-confirmed STI were 23.6% and 87.7%, respectively. CONCLUSION This study demonstrates high STI incidence in HIV-negative women in rural South Africa. Sensitivity of vaginal discharge was poor and STI recurrence rates were high, highlighting the shortcomings of syndromic management in the face of asymptomatic STIs in this setting.

Abstract
BACKGROUND Highly efficacious oral pre-exposure prophylaxis (PrEP) is the global standard for human immunodeficiency virus (HIV)-1 prevention, including in clinical trials of novel PrEP agents using active-comparator designs. The analysis assessed whether incident sexually transmitted infections (STIs) can serve as a surrogate indicator of HIV-1 incidence that might occur in the absence of PrEP. METHODS We analyzed data from 3256 women randomized to placebo groups of oral and vaginal PrEP trials (MTN-003/VOICE and MTN-020/ASPIRE). Regression modeling assessed the correlation between incident individual STIs (Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis, each considered separately) and incident HIV-1. RESULTS Across 18 sites in 4 countries (Malawi, South Africa, Uganda, Zimbabwe), STI and HIV-1 incidences were high: HIV-1 4.9, N gonorrhoeae 5.3, C trachomatis 14.5, and T vaginalis 7.1 per 100 person-years. There was limited correlation between HIV-1 incidence and incidence of individual STIs: N gonorrhoeae (r = 0.02, P = .871), C trachomatis (r = 0.49, P = <.001), and T vaginalis (r = 0.10, P = .481). The modest association with C trachomatis was driven by country-level differences in both C trachomatis and HIV-1, with no statistically significant association within countries. CONCLUSIONS Sexually transmitted infection incidence did not reliably predict HIV-1 incidence at the population level among at-risk African women participating in 2 large PrEP trials.

Abstract
INTRODUCTION The Sub-Saharan African region has some of the world's highest prevalence of sexually transmitted infections (STIs). These infections are considered a major public health concern. Previous studies on the prevalence of C. trachomatis infection in Sub-Saharan Africa have reported rates ranging from 3.1% to 36.8% in pregnant women. This study investigated the prevalence and risk factors associated with C. trachomatis infection in pregnant women. METHODS This study included 735 stored clinical samples that were collected from pregnant women attending the antenatal clinic at King Edward VIII Hospital in Durban from 2018 -2021. C. trachomatis was detected using the Applied BiosystemsTM TaqMan® Assays from stored DNA samples. RESULTS A total of 81/735 (11%) samples tested positive for C. trachomatis infection. The overall median (Q1-Q3) age of the women was 29.0 years (24.0-35.0). The majority of the women who tested positive for C. trachomatis were younger, median (Q1-Q3) age 26.0 years (23.0-32.0) vs 30.0 years (25.0-35.0) for the negative women (p < .001). Of the positive women, 96.3% were unmarried (p=0.014). Older women were less likely to test positive for C. trachomatis infection (OR: 0.93; 95% CI 0.89-0.96 p = .001). Women who were married (OR: 0.25; 95% CI 0.06-0.70; p = .022), co-habiting with their partner (OR: 0.60; 95% CI 0.36-0.98; p = .048) and started having sex at older than 15 years (OR:0.26; 95% CI 0.09-0.87; p = .018) were less likely to test positive for C. trachomatis compared to their counterparts. CONCLUSION This study showed that behavioural and clinical factors were associated with prevalent infections. In order to reduce prevalent infections, stronger risk reduction counselling messages need to be provided from the educational and public health sector.

Abstract
Background Trichomoniasis is the most common sexually transmitted infection (STI) with an estimated annual incidence of 276.4 million cases globally and about 30 million cases in sub-Saharan Africa. Trichomoniasis has been found to be associated with various health complications including pelvic inflammatory disease (PID), significant pregnancy complications, cervical cancer, prostatitis, infertility and the acquisition of human immunodeficiency virus (HIV). Aim Despite being a highly prevalent infection in the African continent, there is no review article published that solely focusses on Trichomonas vaginalis (T. vaginalis) infections in women from Africa. This review aims to fill this gap in the literature. Method An electronic search of online databases was used to identify and extract relevant research articles related to the epidemiology, health complications and treatment associated with T. vaginalis in women from Africa. Results Within the African continent, South Africa has reported the highest prevalence rate for this infection. A combination of sociodemographic, behavioural and biological factors has been shown to be associated with infection. Trichomonas vaginalis infection is associated with the acquisition of HIV, cervical cancer and PIDs in various female populations across the continent. Emerging patterns of resistance to metronidazole have been reported in women from South Africa. Currently, there is no effective vaccine against this pathogen despite efforts at vaccine development. Conclusion Based on the high prevalence and health consequences associated with T. vaginalis, there is a need for improved screening programmes that will lead to early diagnosis, detection of asymptomatic infections and effective treatment regimens.

Abstract
Objective Young women in South Africa are highly affected by sexually transmitted infections (STI), like C. trachomatis (CT) and N. gonorrhoeae (NG). We aimed to estimate the incidence of CT and NG, and its determinants, among young women from the Western Cape, South Africa, participating in an HPV vaccine trial (the EVRI study). Methods HIV-negative women aged 16–24 years were enrolled between October 2012 and July 2013. At enrolment and month 6 participants were screened for CT and NG (Anyplex CT/NG real-time detection method). A questionnaire on demographic and sexual history characteristics was completed at enrolment and month 7. Treatment for CT and/or NG was offered to infected participants. Incidence rates (IR) of CT and NG were estimated. Determinants of incident CT and NG infections were assessed using Poisson regression. Results 365 women were tested for CT and/or NG at least twice. Prevalence of CT and NG at baseline was 33.7% and 10.4%, respectively. Prevalence of co-infection with CT and NG was 7.1%. During 113.3 person-years (py), 48 incident CT infections were diagnosed (IR = 42.4 per 100 py, 95% confidence interval (CI) 31.9–56.2). Twenty-nine incident NG were diagnosed during 139.3 py (IR = 20.8 per 100 py, 95%CI 14.5–29.9). Prevalent CT infection at baseline was associated with incident CT (adjusted incidence rate ratio (aIRR) 5.8, 95%CI 3.0–11.23. More than three lifetime sex partners increased the risk for incident NG (3–4 partners aIRR = 7.3, 95%CI 2.1–26.0; ≥5 partners aIRR = 4.3, 95%CI 1.1–17.5). Conclusions The IR of bacterial STIs among young women in the Western Cape is very high. Besides being previously infected and a higher lifetime number of sex partners, no other risk factors were found for CT and NG, suggesting that the majority of these women were at risk. This indicates the need for intensified prevention of STIs as well as screening and treatment programs to increase sexual health in this region.

Abstract
BACKGROUND Knowledge of sexually transmitted infection (STI) prevalence and risk factors is important to the development of tenofovir-based preexposure prophylaxis (PrEP) and safer conception programming. We introduced STI screening among women at risk for HIV exposure who were participating in a safer conception study in southwestern Uganda. METHODS We enrolled 131 HIV-uninfected women, planning for pregnancy with a partner living with HIV or of unknown HIV serostatus (2018-2019). Women were offered comprehensive safer conception counseling, including PrEP. Participants completed interviewer-administered questionnaires detailing sociodemographics and sexual history. We integrated laboratory screening for chlamydia, gonorrhea, trichomoniasis, and syphilis as a substudy to assess STI prevalence. Multivariable logistic regression was used to determine correlates. RESULTS Ninety-four women completed STI screening (72% of enrolled). Median age was 30 (interquartile range, 26-34) years, and 94% chose PrEP as part of safer conception care. Overall, 24% had STIs: 13% chlamydia, 2% gonorrhea, 6% trichomoniasis, 6% syphilis, and 3% ≥2 STI. Sexually transmitted infection prevalence was associated with younger age (adjusted odds ratio [AOR], 0.87; 95% confidence interval [CI], 0.77-0.99), prior stillbirth (AOR, 5.04; 95% CI, 1.12-22.54), and not feeling vulnerable to HIV (AOR, 16.33; 95% CI, 1.12-237.94). CONCLUSIONS We describe a 24% curable STI prevalence among women at risk for HIV exposure who were planning for pregnancy. These data highlight the importance of integrating laboratory-based STI screening into safer conception programs to maximize the health of HIV-affected women, children, and families.

Trends and correlates of sexually transmitted infections among sexually active Ugandan female youths: evidence from three demographic and health surveys, 2006-2016. BMC Infect Dis 2021; 21:59. [PMID: 33435882 PMCID: PMC7805221 DOI: 10.1186/s12879-020-05732-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Accepted: 12/22/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Female adolescents and young women have the highest risk of curable sexually transmitted infections (STIs) globally. Data on the prevalence of STIs among young women in Uganda are limited. In this study, we investigated the time trends and correlates of STIs among adolescent girls and young women (15-24 years) in Uganda. METHODS We estimated the percentage of women 15-24 years from three recent consecutive Uganda Demographic and Health Surveys (2006, 2011, and 2016), who reported suffering from genital sores, and or genital discharge or any other varginal complaints acquired after sexual intercourse within 12 months of the studies and examined the changes over time. A pooled multivariable logistic regression was used to examine the correlates of reporting an STI in the last 12 months preceding the study. Svyset command in Stata was used to cater for the survey sample design. RESULTS The pooled self-reported STI prevalence was 26.0%. Among these young women, 22.0, 36.3, and 23.1% reported a sexually transmitted infection in 2006, 2011, and 2016 respectively. Between 2006 and 2011, there was evidence of change (+ 14.3%, p < 0.001) in STI prevalence before a significant reduction (- 12.0%, p< 0.001) in 2016. Youths aged 20-24 years reported a higher STI prevalence (27.3%) compared to young participants (23.6%). Correlates of reporting an STI among rural and urban young women were: having multiple total lifetime partners (adjusted odds ratio (aOR 1.6, 95% CI 1.4-1.6), being sexually active in the last 4 weeks (aOR 1.3, 95% CI 1.1-1.6), and being affiliated to Muslim faith (aOR 1.3, 95% CI 1.1-1.6) or other religions (aOR 1.8, 95% CI 1.1-2.9) as compared to Christian were more likely to report an STI. Living in Northern Uganda compared to living in Kampala city was found protective against STIs (aOR 0.5, 95% CI 0.3-0.7). CONCLUSION The prevalence of STIs was high among female youths, 15-24 years. This highlights the need for a comprehensive STIs screening, surveillance, and treatment programme to potentially reduce the burden of STIs in the country.

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 Rates of sexually transmitted infections (STIs) and HIV are highest in the southern United States but vary widely by sex, age, and risk behavior. Current guidelines recommend annual screening for chlamydia, gonorrhea, syphilis, and trichomoniasis in all sexually active women with HIV. METHODS Screening rates and test positivity for chlamydia, gonorrhea, syphilis, and trichomoniasis were determined per calendar year in this retrospective cohort study of women in care at an urban HIV clinic in Birmingham, Alabama, from 2013 to 2015. Chlamydia, gonorrhea, and trichomonas infections were detected by molecular diagnostics and syphilis by serology. A combined end point for chlamydia/gonorrhea/syphilis (STI-3) was created based on similar test positivity and predictors. Predictors of STI-3 were identified using logistic regression and generalized estimating equations. RESULTS Among 745 women with HIV, median age was 46.8 years, 78.8% were black, and 61% were sexually active. In 2015, 83.7% of women were tested for STI. Test positivity was 1.0% for chlamydia, 0.5% for gonorrhea, 1.6% for syphilis, and 13.3% for trichomoniasis. Independent predictors of STI-3 were recent chlamydia or gonorrhea (odds ratio [OR], 3.7; 95% confidence interval [CI], 1-13.4; P = 0.047), public insurance compared with private (OR, 3.5; CI, 1-11.8; P = 0.048), and sex after drugs/alcohol (OR, 3.0; CI, 1.2-8.0; P = 0.025). Women 50 years or older were less likely to have STI (OR, 0.3; CI, 0.1-1; P = 0.040). CONCLUSIONS In a cohort of women engaged in HIV care in the southern United States, detection of chlamydia, gonorrhea, and syphilis was infrequent but trichomoniasis was common. Many women screened for STI were low risk and universal testing strategies warrant evaluation.

Abstract
INTRODUCTION Symptomatic vaginal discharge is a common gynecological condition managed syndromically in most developing countries. In Zimbabwe, women presenting with symptomatic vaginal discharge are treated with empirical regimens that commonly cover both sexually transmitted infections (STIs) and reproductive tract infections, typically including a combination of an intramuscular injection of kanamycin, and oral doxycycline and metronidazole regimens. This study was conducted to determine the current etiology of symptomatic vaginal discharge and assess adequacy of current syndromic management guidelines. METHODS We enrolled 200 women with symptomatic vaginal discharge presenting at 6 STI clinics in Zimbabwe. Microscopy was used to detect bacterial vaginosis and yeast infection. Nucleic acid amplifications tests were used to detect Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, and Mycoplasma genitalium. In addition, serologic testing was performed to detect human immunodeficiency virus (HIV) infection. RESULTS Of the 200 women, 146 (73%) had an etiology detected, including bacterial vaginosis (24.7%); N. gonorrhoeae (24.0%); yeast infection (20.7%); T. vaginalis (19.0%); C. trachomatis (14.0%) and M. genitalium (7.0%). Among women with STIs (N = 90), 62 (68.9%) had a single infection, 18 (20.0%) had a dual infection, and 10 (11.1%) had 3 infections.Of 158 women who consented to HIV testing, 64 (40.5%) were HIV infected.The syndromic management regimen covered 115 (57.5%) of the women in the sample who had gonorrhea, chlamydia, M. genitalium, or bacterial vaginosis, whereas 85 (42.5%) of women were treated without such diagnosis. CONCLUSIONS Among women presenting with symptomatic vaginal discharge, bacterial vaginosis was the most common etiology, and gonorrhea was the most frequently detected STI. The current syndromic management algorithm is suboptimal for coverage of women presenting with symptomatic vaginal discharge; addition of point of care testing could compliment the effectiveness of the syndromic approach.

Prevalence of sexually transmitted infections among young people in South Africa: A nested survey in a health and demographic surveillance site. PLoS Med 2018; 15:e1002512. [PMID: 29485985 PMCID: PMC5828358 DOI: 10.1371/journal.pmed.1002512] [Citation(s) in RCA: 122] [Impact Index Per Article: 20.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2017] [Accepted: 01/19/2018] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Sexually transmitted infections (STIs) and bacterial vaginosis (BV) are associated with increased transmission of HIV, and poor reproductive and sexual health. The burden of STIs/BV among young people is unknown in many high HIV prevalence settings. We conducted an acceptability, feasibility, and prevalence study of home-based sampling for STIs/BV among young men and women aged 15-24 years old in a health and demographic surveillance site (HDSS) in rural KwaZulu-Natal, South Africa. METHODS AND FINDINGS A total of 1,342 young people, stratified by age (15-19 and 20-24 years) and sex were selected from the HDSS sampling frame; 1,171/1,342 (87%) individuals had ≥1 attempted home visit between 4 October 2016 and 31 January 2017, of whom 790 (67%) were successfully contacted. Among the 645 who were contacted and eligible, 447 (69%) enrolled. Consenting/assenting participants were interviewed, and blood, self-collected urine (men), and vaginal swabs (women) were tested for herpes simplex virus type 2 (HSV-2), chlamydia, gonorrhoea, syphilis, trichomoniasis, and BV. Both men and women reported that sample collection was easy. Participants disagreed that sampling was painful; more than half of the participants disagreed that they felt anxious or embarrassed. The weighted prevalence of STIs/BV among men and women, respectively, was 5.3% and 11.2% for chlamydia, 1.5% and 1.8% for gonorrhoea, 0% and 0.4% for active syphilis, 0.6% and 4.6% for trichomoniasis, 16.8% and 28.7% for HSV-2, and 42.1% for BV (women only). Of the women with ≥1 curable STI, 75% reported no symptoms. Factors associated with STIs/BV included having older age, being female, and not being in school or working. Among those who participated in the 2016 HIV serosurvey, the prevalence of HIV was 5.6% among men and 19% among women. Feasibility was impacted by the short study duration and the difficulty finding men at home. CONCLUSIONS A high prevalence of STIs/BV was found in this rural setting with high HIV prevalence in South Africa. Most STIs and HIV infections were asymptomatic and would not have been identified or treated under national syndromic management guidelines. A nested STI/BV survey within a HDSS proved acceptable and feasible. This is a proof of concept for population-based STI surveillance in low- and middle-income countries that could be utilised in the evaluation of STI/HIV prevention and control programmes.
