High study participation but diverging adherence levels: qualitatively unpacking PrEP use among adolescent girls and young women over two years in Eastern Cape, South Africa.

In Southern and Eastern Africa, initiation of daily oral pre-exposure prophylaxis (PrEP) for HIV prevention has been high among adolescent girls and young women (AGYW) offered PrEP. However, persistence and prevention-effective use of PrEP among this critical group continues to be a challenge. We conducted a qualitative sub-study of AGYW from the Community PrEP Study in Eastern Cape Province, South Africa who had high rates of pick up for monthly PrEP refills over two years, but differing levels of PrEP adherence based on tenofovir-diphosphate (TFV-DP) measurements in dried blood spots (DBS). Contrasting 22 AGYW with low versus high levels of TFV-DP in DBS, we qualitatively explored factors which influenced PrEP persistence vs. non-persistence, unique patterns of PrEP use (e.g., discarding or stockpiling), and participant recommendations for improving AGYW prevention-effective use of PrEP in the future. Results showed that PrEP misconceptions and mistrust among participants' social networks negatively influenced adherence. In comparison, supportive families and/or partners and personal trust that PrEP works positively influenced adherence. Those with low adherence described being motivated to come to the site for other study benefits (e.g., reimbursement money, snacks, sanitary pads) and discarding PrEP to avoid stigma associated with being seen with pills. Future PrEP implementation strategies should focus on involving families and partners in PrEP support for AGYW and minimizing PrEP stigma at a community level.Trial registration NCT03977181.

Does It Matter What Screener We Use? A Comparison of Ultra-brief PHQ-4 and E-mwTool-3 Screeners for Anxiety and Depression Among People With and Without HIV.

The burden of depression and anxiety disorders is high in sub-Saharan Africa, especially for people with HIV (PWH). The Patient Health Questionnaire-4 (PHQ-4) and Electronic Mental Wellness Tool-3 (E-mwTool-3) are ultra-brief screening tools for these disorders. We compared the performance of PHQ-4 and E-mwTool-3 for screening MINI-International Neuropsychiatric Interview diagnoses of depression and anxiety among a sample of individuals with and without HIV in two primary care clinics and one general hospital in Maputo City, Mozambique. Areas-under-the-curve (AUC) were calculated along with sensitivities and specificities at a range of cutoffs. For PWH, at a sum score cutoff of ≥ 1, sensitivities were strong: PHQ-4:Depression = 0.843; PHQ-4:Anxiety = 0.786; E-mwTool-3:Depression = 0.843; E-mwTool-3:Anxiety = 0.929. E-mwTool-3 performance was comparable to PHQ-4 among people with and without HIV.

What motivated men to start PrEP? A cross-section of men starting PrEP in Buffalo city municipality, South Africa.

BACKGROUND: Compared to women, South African men are less likely to know their HIV status (78% vs. 89%), have suppressed viral loads (82% vs. 90%), or access HIV prevention services. To achieve epidemic control where heterosexual sexual behavior drives transmission, interventions to improve the uptake of HIV testing services (HTS) and prevention services must also target cis-gendered, heterosexual men. There is limited understanding of these men's needs and wants with regards to accessing pre-exposure prophylaxis (PrEP). METHODS: Adult men (≥ 18 years) from a peri-urban community in Buffalo City Municipality were offered community-based HTS. Those who received a negative HIV test result were offered community-based, same-day oral PrEP initiation. Men initiating PrEP were invited to participate in a study exploring men's HIV prevention needs and reasons for initiating PrEP. An in-depth interview guide, developed using the Network-Individual-Resources model (NIRM), explored men's perceived HIV acquisition risk, prevention needs, and preferences for PrEP initiation. Interviews were conducted by a trained interviewer in isiXhosa or English, audio-recorded and transcribed. Thematic analysis was used, guided by the NIRM to generate findings. RESULTS: Twenty-two men (age range 18-57 years) initiated PrEP and consented to study participation. Men reported elevated HIV acquisition risk associated with alcohol use and condom-less sex with multiple partners as facilitators driving PrEP initiation. They anticipated social support from family members, their main sexual partner and close friends for their PrEP use, and discussed other men as important sources of support for PrEP initiation. Nearly all men expressed positive views of people using PrEP. Participants believed HIV testing would be a barrier for men interested in accessing PrEP. Men recommended that access to PrEP be convenient, rapid, and community-based (i.e., not clinic-based). DISCUSSION: Self-perceived risk for HIV acquisition was a major facilitator for men's PrEP initiation. Although men expressed positive perceptions of PrEP users, they noted that HIV testing may be a barrier to PrEP initiation. Finally, men recommended convenient access points to facilitate PrEP initiation and sustained use. Gender-responsive interventions tailored to men's needs, wants, and voices will facilitate their uptake of HIV prevention services, and help to end the HIV epidemic.

Factors influencing adolescent girls and young women's uptake of community-based PrEP services following home-based HIV testing in Eastern Cape, South Africa: a qualitative study.

Home-based service delivery has been used to improve access to HIV testing and antiretroviral initiation across sub-Saharan Africa, but it has yet to be leveraged to improve pre-exposure prophylaxis (PrEP) uptake. We interviewed 37 adolescent girls and young women (AGYW) in Eastern Cape, South Africa to explore why they chose to initiate PrEP or not following home-based HIV testing and referral for PrEP, and what influenced time to PrEP initiation. Participants reported that home visits provided a source of trusted information and a way to involve family members in their PrEP initiation decisions, motivating some to start PrEP. AGYW who initiated PrEP were more likely to qualitatively perceive themselves to be at high risk for HIV compared with those who never initiated PrEP. Integrating home-based HIV testing with PrEP education and referral may be a valuable way to reduce familial barriers and boost PrEP uptake among AGYW in South Africa.

Impact of aetiological screening of sexually transmitted infections during pregnancy on pregnancy outcomes in South Africa.

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.

Prevalence, incidence and associated risk factors of STIs during pregnancy in South Africa.

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.

Molecular epidemiological analysis of Mycoplasma genitalium shows low prevalence of azithromycin resistance and a well-established epidemic in South Africa.

OBJECTIVES: Macrolide resistance in Mycoplasma genitalium is emerging globally. There is paucity of data from sub-Saharan Africa where syndromic management is used to treat sexually transmitted infections (STIs). We conducted a molecular epidemiological study to determine the prevalence of azithromycin resistance and epidemic diversity of M. genitalium infections in South Africa. METHODS: We analysed 90 M. genitalium-positive specimens that had been collected consecutively from men and women (50% symptomatic) from geographically diverse communities across the northern part of South Africa between 2015 and 2019. Melting curve analysis followed by targeted sequencing of the 23S rRNA gene was performed to detect azithromycin resistance. Molecular typing was done through single nucleotide polymorphism (SNP) analysis of the MG191 gene and short tandem repeats (STR) assessment of the MG309 gene. An overview of all published M. genitalium sequence types was generated and novel sequence types identified in this study were allocated numbers accordingly. RESULTS: Azithromycin resistance was detected in 1/90 M. genitalium-positive specimens (1.1%; 95% CI 0% to 3.3%) as conferred by A2071G mutation; this strain also harboured a C234T mutation in the parC gene with wild type gyrA gene. SNP typing and STR assessment was successful in 38/90 specimens (42%) and showed a genetically diverse epidemic, without geographic clustering, with eight novel sequence types identified. CONCLUSION: This is the first study that determines resistance in M. genitalium infection since introduction of azithromycin in the syndromic management regimen for STIs in South Africa in 2015. Despite a well-established epidemic, azithromycin-resistant M. genitalium infection is still uncommon in the public healthcare sector. However, it has the potential to undermine the effectiveness of syndromic management. Introduction of molecular diagnostics and continuous surveillance are warranted for early detection emergence of resistance.

Single-Dose Azithromycin for Genital Lymphogranuloma Venereum Biovar Chlamydia trachomatis Infection in HIV-Infected Women in South Africa: An Observational Study.

ABSTRACT: We conducted an observational study of lymphogranuloma venereum (LGV) biovar Chlamydia trachomatis infection in HIV-infected women in South Africa. The LGV biovar was detected in vaginal specimens of 17 (20%) of 85 women with C. trachomatis infection; 29% were symptomatic. All cases were negative for the LGV biovar after single-dose azithromycin.

"I got tested at home, the help came to me": acceptability and feasibility of home-based TB testing of household contacts using portable molecular diagnostics in South Africa.

OBJECTIVE: The effectiveness of household contact investigations is limited by low referral uptake for clinic-based TB testing by symptomatic household contacts. We qualitatively investigated the acceptability and perceived benefits of home-based TB testing using a portable GeneXpert-I instrument (GX-I) in an urban South African township. METHODS: In-depth interviews were conducted with household contacts tested and those that observed testing. Semi-structured interviews explored household contact's understanding of TB, perceptions of the GX-I device and testing procedures, confidentiality, willingness to refer others, and views on home- vs. clinic-based testing. Focus group discussions with home-based TB testing implementing staff assessed operational considerations for scale-up. Data were analysed using a constant comparison approach to qualitatively evaluate the acceptability and feasibility of home-based TB testing. RESULTS: Thirty in-depth interviews and two focus group discussions were conducted. Observing one's own sputum being tested resulted in an emergent trust in home-based TB testing, the GX-I device and one's test results. Home-based TB testing was considered convenient, helped to overcome apathy towards testing and mitigated barriers to clinic-based testing. Perceptions that home-based TB testing contributes to improved household and community health resulted in an emergent theme of alleviation of health insecurities. Operational concerns regarding inadvertent disclosure of one's diagnosis to household members and time spent in people's homes were identified. CONCLUSIONS: Home-based TB testing was acceptable and feasible. Individuals expressed belief in the machine by being able to witness the testing process. Though most themes mirrored qualitative studies of home-based HIV testing, the alleviation of health insecurities theme is unique to home-based TB testing. Future research must evaluate the impact of home-based TB testing on case finding yield, time-to-treatment initiation and household outcomes.

OBJECTIF: L'efficacité des enquêtes sur les contacts familiaux est limitée par le faible taux de respect de l'orientation pour le dépistage de la tuberculose (TB) en clinique par les contacts familiaux symptomatiques. Nous avons investigué qualitativement l'acceptabilité et les avantages perçus du dépistage de la TB à domicile à l'aide d'un dispositif portable GeneXpert-I (GX-I) dans une ville urbaine sud-africaine. MÉTHODES: Des entretiens approfondis ont été menés avec des contacts familiaux testés et ceux qui ont observé la pratique des tests. Des entretiens semi-structurés ont permis d'explorer la compréhension de la TB par les contacts familiaux, les perceptions sur le dispositif GX-I et les procédures de test, la confidentialité, la volonté de référer d'autres personnes et les opinions sur le dépistage à domicile ou en clinique. Des discussions de groupe focalisées avec le personnel chargé de la mise en œuvre du dépistage de la TB à domicile ont évalué les considérations opérationnelles pour le déploiement. Les données ont été analysées en utilisant une approche de comparaison constante pour évaluer qualitativement l'acceptabilité et la faisabilité du dépistage de la TB à domicile. RÉSULTATS: Trente entretiens approfondis et deux discussions de groupe ont été menés. L'observation de ses propres expectorations testées a conduit à une émergente de confiance dans le dépistage de la TB à domicile, le dispositif GX-I et les résultats des tests. Le dépistage de la TB à domicile était considéré comme pratique, aidait à surmonter l'apathie envers le dépistage et atténuait les obstacles au dépistage en clinique. La perception selon laquelle le dépistage de la TB à domicile contribue à l'amélioration de la santé des ménages et de la communauté a donné lieu à l'émergence du thème de la réduction des insécurités sanitaires. Des préoccupations opérationnelles concernant la divulgation par inadvertance de son diagnostic aux membres du ménage et le temps passé au domicile des personnes ont été identifiées. CONCLUSION: Le dépistage de la TB à domicile était acceptable et faisable. Les individus ont exprimé leur croyance en la machine en étant en mesure d'assister au processus de test. Bien que la plupart des thèmes reflètent des études qualitatives sur le dépistage du VIH à domicile, le thème de l'atténuation des insécurités sanitaires est unique au dépistage de la TB à domicile. Les recherches futures doivent évaluer l'impact du dépistage de la TB à domicile sur le rendement de la recherche des cas, le délai de mise en route du traitement et les résultats au sein des ménages.

Sexually Transmitted Infections in Pregnancy: A Narrative Review of the Global Research Gaps, Challenges, and Opportunities.

BACKGROUND: Sexually transmitted infections (STI), such as chlamydial, gonorrheal, and trichomonal infections, are prevalent in pregnant women in many countries and are widely reported to be associated with increased risk of poor maternal and neonatal outcomes. Syndromic STI management is frequently used in pregnant women in low- and middle-income countries, yet its low specificity and sensitivity lead to both overtreatment and undertreatment. Etiologic screening for chlamydial, gonorrheal, and/or trichomonal infection in all pregnant women combined with targeted treatment might be an effective intervention. However, the evidence base is insufficient to support the development of global recommendations. We aimed to describe key considerations and knowledge gaps regarding chlamydial, gonorrheal, and trichomonal screening during pregnancy to inform future research needed for developing guidelines for low- and middle-income countries. METHODS: We conducted a narrative review based on PubMed and clinical trials registry searches through January 20, 2020, guidelines review, and expert opinion. We summarized our findings using the frameworks adopted by the World Health Organization for guideline development. RESULTS: Adverse maternal-child health outcomes of potential interest are wide-ranging and variably defined. No completed randomized controlled trials on etiologic screening and targeted treatment were identified. Evidence from observational studies was limited, and trials of presumptive STI treatment have shown mixed results. Subgroups that might benefit from specific recommendations were identified. Evidence on harms was limited. Cost-effectiveness was influenced by STI prevalence and availability of testing infrastructure and high-accuracy/low-cost tests. Preliminary data suggested high patient acceptability. DISCUSSION: Preliminary data on harms, acceptability, and feasibility and the availability of emerging test technologies suggest that etiologic STI screening deserves further evaluation as a potential tool to improve maternal and neonatal health outcomes worldwide.

The role of trust and health literacy in nurse-delivered point-of-care STI testing for pregnant women living with HIV, Tshwane District, South Africa.

BACKGROUND: Sexually transmitted infections (STIs) during pregnancy result in neonatal morbidity and mortality, and may increase mother-to-child-transmission of HIV. Yet the World Health Organization's current syndromic management guidelines for STIs leaves most pregnant women undiagnosed and untreated. Point-of-care (POC) diagnostic tests for STIs can drastically improve detection and treatment. Though acceptable and feasible, poor medication adherence and re-infection due to lack of partner treatment threaten the programmatic effectiveness of POC diagnostic programmes. METHODS: To engender patient-provider trust, and improve medication adherence and disclosure of STI status to sexual partners, we trained study nurses in compassionate care, good clinical practices and motivational interviewing. Using qualitative methods, we explored the role patient-provider communications may play in supporting treatment adherence and STI disclosure to sexual partners. Nurses were provided training in motivational interviewing, compassionate care and good clinical practices. Participants were interviewed using a semi-structured protocol, with domains including STI testing experience, patient-provider communication, and HIV and STI disclosure. Interviews were audio-recorded, transcribed and analyzed using a constant comparison approach. RESULTS: Twenty-eight participants treated for Chlamydia trachomatis (CT), Trichomonas vaginalis (TV), and/or Neisseria gonorrhea (NG) were interviewed. Participants described strong communications and trusting relationships with nurses trained in patient-centered care training and implementing POC STI diagnostic testing. However, women described a delayed trust in treatment until their symptoms resolved. Women expressed a limited recall of their exact diagnosis, which impacted their ability to fully disclose their STI status to sexual partners. CONCLUSIONS: We recommend implementing patient health literacy programmes as part of POC services to support women in remembering and disclosing their specific STI diagnosis to sexual partners, which may facilitate partner treatment uptake and thus decrease the risk of re-infection.

Mixed-methods evaluation of mental healthcare integration into tuberculosis and maternal-child healthcare services of four South African districts.

BACKGROUND: The South African National Mental Health Policy Framework and Strategic Plan 2013-2020 was adopted to address the country's substantial burden and inadequate treatment of mental illness. It outlines measures toward the goal of full integration of mental health services into primary care by 2020. To evaluate progress and challenges in implementation, we conducted a mixed-methods assessment of mental health service provision in tuberculosis and maternal-child healthcare services of four districts in South Africa. METHODS: Forty clinics (ten per district) were purposively selected to represent both urban and rural locations. District-level program managers (DPMs) for mental health, tuberculosis, and maternal-child healthcare were qualitatively interviewed about district policy and procedures for management of mental illness and challenges in integrating mental health services into primary care. Clinic nurses and mental health practitioners (MHPs) completed a quantitative questionnaire to assess their engagement with stepped care for patients with mental illness. Qualitative and quantitative data were collected concurrently and compared to triangulate progress in implementation of integrated services. RESULTS: A total of 59 nurses and 17 MHPs completed questionnaires, and nine DPMs were interviewed (total n = 85). DPMs indicated that nurses should screen for mental illness at every patient visit, although only 43 (73%) nurses reported conducting universal screening and 26 (44%) reported using a specific screening tool. For patients who screen positive for mental illness, DPMs described a stepped-care approach in which MHPs diagnose patients and then treat or refer them to specialized care. However, only 7 (41%) MHPs indicated that they diagnose mental illness and 14 (82%) offer any treatment for mental illness. Addressing challenges to current integration efforts, DPMs highlighted 1) insufficient funding and material resources, 2) poor coordination at the district administrative level, and 3) low mental health awareness in district administration and the general population. CONCLUSIONS: Though some progress has been made toward integration of mental health services into primary care settings, there is a substantial lack of training and clarity of roles for nurses and MHPs. To enhance implementation, increased efforts must be directed toward improving district-level administrative coordination, mental health awareness, and financial and material resources.

Factors influencing sexually transmissible infection disclosure to male partners by HIV-positive pregnant women in Pretoria townships, South Africa: a qualitative study.

Background Sexually transmissible infections (STI) may increase the risk of mother-to-child transmission (MTCT) of HIV. However, diagnostic testing and targeted treatment of STI (STI-TT) during pregnancy is not standard care in South Africa. METHODS: A qualitative study was nested in a STI-TT intervention to investigate motivating and enabling factors associated with STI test results disclosure to sexual partners. A semi-structured interview protocol covered partner communication, HIV and STI disclosure, financial security and relationships dynamics. Interviews were conducted in participants' preferred language, audio-recorded, transcribed into English and analysed using a constant comparison approach. The study was conducted in two townships in Pretoria, South Africa. RESULTS: Twenty-eight HIV-positive pregnant women were interviewed. Based on the interviews, two disclosure experiences for women were identified - those with vulnerable experiences and those with self-enabling experiences within their partnerships. Vulnerable women discussed intimate partner violence (IPV) and fear of relationship dissolution as factors influencing their test result disclosure. Self-enabled women discussed their ability to talk with their partners about STI and HIV infections and the influence of multiple concurrent partnerships in the acquisition of HIV/STIs. Both groups of women were concerned about men's health behaviours, and all cited the health and development of their unborn child as a key motivator for test result disclosure. CONCLUSIONS: Improved counselling and support for pregnant women to disclose their STI test results to their partners may improve the impact of STI diagnostic testing during pregnancy by improving partner treatment uptake and thus reducing the risk of re-infection.

Sexual Behaviors of Human Immunodeficiency Virus-Infected Pregnant Women and Factors Associated With Sexually Transmitted Infection in South Africa.

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.

Acceptability and Feasibility of Rapid Chlamydial, Gonococcal, and Trichomonal Screening and Treatment in Pregnant Women in 6 Low- to Middle-Income Countries.

BACKGROUND: Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) infections during pregnancy are linked with adverse birth outcomes. However, few countries have prenatal CT, NG, or TV screening programs. In this study, we aimed to evaluate the acceptability and feasibility of CT, NG, and TV screening and treatment among pregnant women across 6 low- to middle-income countries. METHODS: A total of 1817 pregnant women were screened for CT, NG, and TV in Botswana, the Democratic Republic of Congo, Haiti, South Africa, and Vietnam. An additional 640 pregnant women were screened for CT in Peru. Screening occurred between December 2012 and October 2017. Acceptability of screening was evaluated at each site as the proportion of eligible women who agreed to participate in screening. Feasibility of treatment was calculated as the proportion of women who tested positive that received treatment. RESULTS: Acceptability of screening and feasibility of treatment was high across all 6 sites. Acceptability of screening ranged from 85% to 99%, and feasibility of treatment ranged from 91% to 100%. DISCUSSION: The high acceptability and feasibility of screening and treatment of CT, NG, and TV among pregnant women supports further research to evaluate the cost-effectiveness of prenatal CT, NG, and TV screening programs.

Prevalence and Detection of Trichomonas vaginalis in HIV-Infected Pregnant Women.

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.
