RESUMO
We evaluated changes in female genital schistosomiasis (FGS) 6 to 12 months after praziquantel treatment among 43 adult Zambian women. Most women (60%) experienced decreased FGS severity and 23% experienced complete lesion resolution. This is the first study to demonstrate a meaningful effect of praziquantel treatment of FGS in adult women.

Negotiating sexual agreements in combination with couples' voluntary HIV counseling and testing (CVCT) may help further reduce HIV transmission in Zambian concordant HIV-negative couples (CNC). Though CVCT has been shown to reduce HIV transmission in CNC by 47%, approximately half of residual infections occur in this group. We developed a "Strengthening Our Vows" video session to foster communication and negotiation of explicit sexual agreements to reduce concurrent sexual exposures and prevent HIV transmission to the spouse due to unprotected, extramarital sex. CNC were recruited through CVCT services at five clinics in Lusaka and Ndola in 2016. Enrolled CNC attending the facilitated group video sessions were encouraged to discuss sexual agreements at home and return 1-2 weeks later for follow-up assessment. One-fourth of the 580 CNC returning reported a history of extramarital partners and/or a sexually transmitted infection (STI) prior to enrollment. More than 95% reported a friendly, supportive 15-60 min negotiation culminating in an agreement to remain monogamous or disclose sexual contacts and use condoms together until a repeat HIV test 30 days after an outside sexual exposure. Two-thirds of participants identified at least one threat to adherence of their agreements including alcohol use, financial pressures, travel, discord in the home, and post-partum or menstrual abstinence. CNC negotiated explicit sexual agreements to avoid exposure to HIV through concurrent partnerships and protect the spouse in the event of an outside sexual contact. Open communication was a consistent theme to facilitate mutual protective efforts. Long-term follow-up of HIV/STI incidence is ongoing to assess the impact of these agreements.Trial registration This sub-study is part of a trial retrospectively registered on ClinicalTrials.gov (Identifier: NCT02744586) on April 20, 2016.

BACKGROUND: From 2019 to 2021, Rwandan residents of the border with the Democratic Republic of the Congo were offered the Ad26.ZEBOV (adenovirus type 26 vector vaccine encoding Ebola virus glycoprotein) and MVA-BN-Filo (modified vaccinia virus Ankara vector vaccine, encoding glycoproteins from Ebola, Sudan, Marburg, and nucleoprotein from Tai Forest viruses) Ebola vaccine regimen. METHODS: Nonpregnant persons aged ≥2 years were eligible. Unsolicited adverse events (UAEs) were reported through phone calls or visits, and serious adverse events (SAEs) were recorded per International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use guidelines. RESULTS: Following Ad26.ZEBOV, UAEs were reported by 0.68% of 216 113 vaccinees and were more common in younger children (aged 2-8 years, 1.2%) compared with older children (aged 9-17 years, 0.4%) and adults (aged ≥18 years, 0.7%). Fever and headache were the most reported symptoms. All 17 SAEs related to vaccine were in children aged 2-8 years (10 postvaccination febrile convulsions ± gastroenteritis and 7 fever and/or gastroenteritis). The incidence of febrile seizures was 8 of 26 062 (0.031%) prior to initiation of routine acetaminophen in December 2020 and 2 of 15 897 (0.013%) thereafter. Nonobstetric SAEs were similar in males and females. All 20 deaths were unrelated to vaccination. Young girls and adult women with UAEs were less likely to receive the second dose than those without UAEs. Seven unrelated SAEs occurred in 203 267 MVA-BN-Filo recipients. CONCLUSIONS: Postvaccination febrile convulsions in young children were rare but not previously described after Ad26.ZEBOV and were reduced with routine acetaminophen. The regimen was otherwise safe and well-tolerated.

INTRODUCTION: Rwanda has high unmet need for family planning (FP), especially in the postpartum period when women are advised to space pregnancies at least two years for improved maternal-child health. Despite interest in the copper intrauterine device (IUD), a highly cost-effective method, access and uptake remain low. This study aimed to determine factors associated with postpartum IUD (PPIUD) uptake after postpartum family planning (PPFP) counseling as well as provider perceptions of facilitators and barriers to clients' PPIUD uptake. METHODS: Postpartum women who received PPFP counseling and were less than 6 weeks postpartum were recruited for a case-control study in Kigali, Rwanda in 2018. We recruited n = 74 women who had accepted and n = 91 women who had declined the PPIUD. Multivariate logistic regression analyses evaluated associations between women's socio-demographics, FP knowledge and decision-making, and the outcome of PPIUD uptake. Six focus groups (FGs) were conducted with FP providers (n = 24) and community health workers (n = 17) trained to deliver PPFP counseling to assess perceptions of PPFP counseling and facilitators and barriers to PPIUD uptake. FG discussions were recorded, translated, and analyzed for themes. RESULTS: Factors associated (P<0.1) with PPIUD uptake included citing its non-hormonal nature, effectiveness, and duration of protection against pregnancy as advantages. Exclusive male partner control over FP decisions (relative to women's control or joint decision-making) was associated with non-use. Overall, limited knowledge about some aspects of the PPIUD persisted among clients even after counseling. Provider FGs highlighted client concerns, inconsistent FP messaging, and lack of male partner involvement as factors influencing non-use. CONCLUSIONS: Knowledge of the IUD and its benefits was associated with PPIUD uptake. There is need to refine PPFP counseling messages to address remaining knowledge gaps and concerns. Additionally, male partner involvement in FP counseling and decisions with their partners could be a key strategy to increase both PPIUD and FP uptake in Rwanda.

BACKGROUND: Risks to mother and fetus following Ebola virus infection are very high. Evaluation of safety and immunogenicity of non-replicating Ebola vaccine candidates is a priority for use in pregnant women. This is the protocol for a randomized, open-label, single-center phase 3 clinical trial of the safety, reactogenicity, and immunogenicity of the 2-dose Ebola vaccine regimen in healthy adult pregnant women. This 2-dose regimen has been shown to be safe, judged effective, and approved in non-pregnant populations. METHODS: A total of 2000 adult (≥ 18 years of age) pregnant women will be enrolled from antenatal care facilities in Western Rwanda and randomized (1:1) to receive the 2-dose Ebola vaccine regimen (Ad26.ZEBOV, MVA-BN-Filo (group A)) or control (unvaccinated pregnant women (group B)). The primary objectives are to (1) assess adverse maternal/fetal outcomes in randomized pregnant women up to 1.5 months after delivery and (2) assess adverse neonatal/infant outcomes in neonates/infants born to randomized women up to 3.5 months after birth. The frequency and relatedness of all serious adverse events in women and newborns from randomization or birth, respectively, until study end will be reported. The reactogenicity and unsolicited adverse events of the 2-dose Ebola vaccine regimen in all vaccinated pregnant women (group A) will be reported. We will also assess the immunogenicity of the 2-dose Ebola vaccine regimen in 150 pregnant women who are anticipated to receive both vaccine doses within the course of their pregnancy (a subset of the 1000 pregnant vaccinated women from group A) compared to 150 non-pregnant women vaccinated after delivery (a subset of group B). The persistence of maternal antibodies in 75 infants born to women from the group A subset will be assessed. Exploratory analyses include assessment of acceptability of the 2-dose Ebola vaccine regimen among group A and assessment of maternal antibodies in breast milk in 50 women from group A and 10 controls (women from group B prior to vaccination). DISCUSSION: This study is intended to support a label variation to relax restrictions on use in pregnant women, a vulnerable population with high medical need.

Measles is a vaccine-preventable viral disease whose vaccination coverage remains low in Zambia, where the target group for vaccination is children aged 9 to 18 months. In addition to inadequate measles vaccination coverage among children, few studies address potential resultant immunity gaps among adults. We analyzed data from a simulated HIV vaccine efficacy trial (SiVET) conducted from 2015-2017 among adult Zambian women of childbearing age to determine measles antibody seroprevalence before and after vaccination with the measles, mumps and rubella (MMR) vaccine. We used MMR vaccine as a substitute for an experimental HIV vaccine as part of a simulation exercise to prepare for an HIV vaccine efficacy trial. We found that 75% of women had measles antibodies prior to receiving MMR, which increased to 98% after vaccination. In contrast, mumps and rubella antibody prevalence was high before (93% and 97%, respectively) and after (99% and 100%, respectively) vaccination. The low baseline measles seropositivity suggests an immunity gap among women of childbearing age. We recommend that measles vaccination programs target women of childbearing age, who can pass antibodies on to neonates. Moreover, administering the MMR vaccine to clinical trial candidates could prevent measles, mumps or rubella-related adverse events during actual trials.

BACKGROUND: Though the Rwandan Ministry of Health (MOH) prioritizes the scale-up of postpartum family planning (PPFP) programs, uptake and sustainability of PPFP services in Rwanda are low. Furthermore, highly effective long-acting reversible contraceptive method use (LARC), key in effective PPFP programs, is specifically low in Rwanda. We previously pilot tested a supply-demand intervention which significantly increased the use of postpartum LARC (PPLARC) in Rwandan government clinics. In this protocol, we use an implementation science framework to test whether our intervention is adaptable to large-scale implementation, cost-effective, and sustainable. METHODS: In a type 2 effectiveness-implementation hybrid study, we will evaluate the impact of our PPFP intervention on postpartum LARC (PPLARC) uptake in a clinic-randomized trial in 12 high-volume health facilities in Kigali, Rwanda. We will evaluate this hybrid study using the RE-AIM framework. The independent effectiveness of each PPFP demand creation strategy on PPLARC uptake among antenatal clinic attendees who later deliver in a study facility will be estimated. To assess sustainability, we will assess the intervention adoption, implementation, and maintenance. Finally, we will evaluate intervention cost-effectiveness and develop a national costed implementation plan. DISCUSSION: Adaptability and sustainability within government facilities are critical aspects of our proposal, and the MOH and other local stakeholders will be engaged from the outset. We expect to deliver PPFP counseling to over 21,000 women/couples during the project period. We hypothesize that the intervention will significantly increase the number of stakeholders engaged, PPFP providers and promoters trained, couples/clients receiving information about PPFP, and PPLARC uptake comparing intervention versus standard of care. We expect PPFP client satisfaction will be high. Finally, we also hypothesize that the intervention will be cost-saving relative to the standard of care. This intervention could dramatically reduce unintended pregnancy and abortion, as well as improve maternal and newborn health. Our PPFP implementation model is designed to be replicable and expandable to other countries in the region which similarly have a high unmet need for PPFP.

Observing sexual behaviour change over time could help develop behavioural HIV prevention interventions for female sex workers in Zambia, where these interventions are lacking. We investigated the evolution of consistent condom use among female sex workers and their clients and steady partners. Participants were recruited into an HIV incidence cohort from 2012 to 2017. At each visit, women received HIV counselling and testing, screening for sexually transmitted infections (STIs) and free condoms. Our outcome was reported consistent (100%) condom use in the previous month with steady partners, repeat clients, and non-repeat clients. Consistent condom use at baseline was highest with non-repeat clients (36%) followed by repeat clients (27%) and steady partners (17%). Consistent condom use between baseline and Month 42 increased by 35% with steady partners, 39% with repeat clients and 41% with non-repeat clients. Access to condoms, HIV/STI counselling and testing promoted positive sexual behaviour change.

BACKGROUND: There is unmet need for family planning in Rwanda. We previously developed an evidence-based couples' family planning counseling (C)FPC program in the capital city that combines: (1) fertility goal-based family planning counseling with a focus on long-acting reversible contraceptive (LARC) for couples wishing to delay pregnancy; (2) health center capacity building for provision of LARC methods, and (3) LARC promotion by community health workers (CHW) trained in community-based provision of oral and injectable contraception. From 2015 to 2016, this service was integrated into eight government health centers in Kigali, reaching 6072 clients and resulting in 5743 LARC insertions. METHODS: From May to July 2016, we conducted cross-sectional health center needs assessments in 30 rural health centers using surveys, key informant interviews, logbook extraction, and structured observations. The assessment focused on the infrastructure, materials, and human resources needed for LARC demand creation and provision. RESULTS: Few nurses had received training in LARC insertion [41% implant, 27% intrauterine device (IUD)]. All health centers reported working with CHW, but none trained in LARC promotion. Health centers had limited numbers of IUDs (median 10), implants (median 39), functional gynecological exam tables (median 2), and lamps for viewing the cervix (median 0). Many did not have backup power supplies (40%). Most health centers reported no funding partners for family planning assistance (60%). Per national guidelines, couples' voluntary HIV counseling and testing (CVCT) was provided at the first antenatal visit at all clinics, reaching over 80% of pregnant women and their partners. However, only 10% of health centers had integrated family planning and HIV services. CONCLUSIONS: To successfully implement (C)FPC and LARC services in rural health centers across Rwanda, material and human resource capacity for LARC provision will need to be greatly strengthened through equipment (gynecological exam tables, sterilization capacity, lamps, and backup power supplies), provider trainings and follow-up supervision, and new funding partnerships. Simultaneously, awareness of LARC methods will need to be increased among couples through education and promotion to ensure that demand and supply scale up together. The potential for integrating (C)FPC with ongoing CVCT in antenatal clinics is unique in Africa and should be pursued.

BACKGROUND: Heterosexual couples contribute to most new HIV infections in areas of generalized HIV epidemics in sub-Saharan Africa. After Couples' Voluntary HIV Counseling and Testing (CVCT), heterosexual concordant HIV negative couples (CNC) in cohabiting unions contribute to approximately 47% of residual new infections in couples. These infections are attributed to concurrent sexual partners, a key driver of the HIV epidemic in Zambia. METHODS/DESIGN: Ten Zambian government clinics in two of the largest cities were randomized in matched pairs to a Strengthening Our Vows (SOV) intervention or a Good Health Package (GHP) comparison arm. SOV addressed preventing HIV infection from concurrent partners and protecting spouses after exposures outside the relationship. GHP focused on handwashing; water chlorination; household deworming; and screening for hypertension, diabetes and schistosomiasis. CNC were referred from CVCT services in government clinics. Follow-up includes post-intervention questionnaires and outcome assessments through 60 months. Longitudinal outcomes of interest include self-report and laboratory markers of condomless sex with outside partners and reported sexual agreements. We present baseline characteristics and factors associated with study arm and reported risk using descriptive statistics. RESULTS: The mean age of men was 32 and 26 for women. On average, couples cohabited for 6 years and had 2 children. Baseline analyses demonstrated some failures of randomization by study arm which will be considered in future primary analyses of longitudinal data. An HIV/STI risk factor composite was not different in the two study arms. Almost one-quarter of couples had an HIV risk factor at baseline. DISCUSSION: In preparation for future biomedical and behavioral interventions in sub-Saharan Africa, it is critical to understand and decrease HIV risk within CNC.
RESUMO
INTRODUCTION: The longstanding inadequacies of syndromic management for genital ulceration and inflammation are well-described. The Rwanda National Guidelines for sexually transmitted infection (STI) syndromic management are not yet informed by the local prevalence and correlates of STI etiologies, a component World Health Organization guidelines stress as critical to optimize locally relevant algorithms. METHODS: Radio announcements and pharmacists recruited symptomatic patients to seek free STI services in Kigali. Clients who sought services were asked to refer sexual partners and symptomatic friends. Demographic, behavioral risk factor, medical history, and symptom data were collected. Genital exams were performed by trained research nurses and physicians. We conducted phlebotomy for rapid HIV and rapid plasma reagin (RPR) serologies and vaginal pool swab for microscopy of wet preparation to diagnose Trichomonas vaginalis (TV), bacterial vaginosis (BV), and vaginal Candida albicans (VCA). GeneXpert testing for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) were conducted. Here we assess factors associated with diagnosis of NG and CT in men and women. We also explore factors associated with TV, BV and VCA in women. Finally, we describe genital ulcer and RPR results by HIV status, gender, and circumcision in men. RESULTS: Among 974 men (with 1013 visits), 20% were positive for CT and 74% were positive for NG. Among 569 women (with 579 visits), 17% were positive for CT and 27% were positive for NG. In multivariate analyses, factors associated with CT in men included younger age, responding to radio advertisements, <17 days since suspected exposure, and not having dysuria. Factors associated with NG in men included not having higher education or full-time employment, <17 days since suspected exposure, not reporting a genital ulcer, and having urethral discharge on physical exam. Factors associated with CT in women included younger age and < = 10 days with symptoms. Factors associated with NG in women included younger age, lower education and lack of full-time employment, sometimes using condoms vs. never, using hormonal vs. non-hormonal contraception, not having genital ulcer or itching, having symptoms < = 10 days, HIV+ status, having BV, endocervical discharge noted on speculum exam, and negative vaginal wet mount for VCA. In multivariate analyses, only reporting >1 partner was associated with BV; being single and RPR+ was associated with TV; and having < = 1 partner in the last month, being pregnant, genital itching, discharge, and being HIV and RPR negative were associated with VCA. Genital ulcers and positive RPR were associated with being HIV+ and lack of circumcision among men. HIV+ women were more likely to be RPR+. In HIV+ men and women, ulcers were more likely to be herpetic rather than syphilitic compared with their HIV- counterparts. CONCLUSIONS: Syndromic management guidelines in Rwanda can be improved with consideration of the prevalence of confirmed infections from this study of symptomatic men and women representative of those who would seek care at government health centers. Inclusion of demographic and risk factor measures shown to be predictive of STI and non-STI dysbioses may also increase diagnostic accuracy.

BACKGROUND: Algorithms that bridge the gap between syndromic sexually transmitted infection (STI) management and treatment based in realistic diagnostic options and local epidemiology are urgently needed across Africa. Our objective was to develop and validate a risk algorithm for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) diagnosis among symptomatic Rwandan women and to compare risk algorithm performance to the current Rwandan National Criteria for NG/CT diagnosis. METHODS: The risk algorithm was derived in a cohort (n = 468) comprised of symptomatic women in Kigali who sought free screening and treatment for sexually transmitted infections and vaginal dysbioses at our research site. We used logistic regression to derive a risk algorithm for prediction of NG/CT infection. Ten-fold cross-validation internally validated the risk algorithm. We applied the risk algorithm to an external validation cohort also comprised of symptomatic Rwandan women (n = 305). Measures of calibration, discrimination, and screening performance of our risk algorithm compared to the current Rwandan National Criteria are presented. RESULTS: The prevalence of NG/CT in the derivation cohort was 34.6%. The risk algorithm included: age < =25, having no/primary education, not having full-time employment, using condoms only sometimes, not reporting genital itching, testing negative for vaginal candida, and testing positive for bacterial vaginosis. The model was well calibrated (Hosmer-Lemeshow p = 0.831). Higher risk scores were significantly associated with increased prevalence of NG/CT infection (p < 0.001). Using a cut-point score of > = 5, the risk algorithm had a sensitivity of 81%, specificity of 54%, positive predictive value (PPV) of 48%, and negative predictive value (NPV) of 85%. Internal and external validation showed similar predictive ability of the risk algorithm, which outperformed the Rwandan National Criteria. Applying the Rwandan National Criteria cutoff of > = 2 (the current cutoff) to our derivation cohort had a sensitivity of 26%, specificity of 89%, PPV of 55%, and NPV of 69%. CONCLUSIONS: These data support use of a locally relevant, evidence-based risk algorithm to significantly reduce the number of untreated NG/CT cases in symptomatic Rwandan women. The risk algorithm could be a cost-effective way to target treatment to those at highest NG/CT risk. The algorithm could also aid in sexually transmitted infection risk and prevention communication between providers and clients.

BACKGROUND: We explored the role of genital abnormalities and hormonal contraception in human immunodeficiency virus (HIV) transmission among heterosexual serodifferent couples in Rwanda. METHODS: From 2002 to 2011, HIV-serodifferent couples who were not using antiretroviral treatment were followed up, and sociodemographic and clinical data were collected, family planning provided, and HIV-negative partners retested. Couples were assessed for genital ulcers; nonulcerative genital sexually transmitted infection (STIs), including gonorrhea, chlamydia, and trichomoniasis; and non-STI vaginal infections, including bacterial vaginosis and candida. Multivariable models evaluated associations between covariates and HIV transmission genetically linked to the index partner. RESULTS: Among 877 couples in which the man was HIV positive, 37 linked transmissions occurred. Factors associated with women's HIV acquisition included genital ulceration in the female partner (adjusted hazard ratio, 14.1) and nonulcerative STI in the male partner (8.6). Among 955 couples in which the woman was HIV positive, 46 linked transmissions occurred. Factors associated with HIV acquisition in men included nonulcerative STI in the female partner (adjusted hazard ratio, 4.4), non-STI vaginal dysbiosis (7.1), and genital ulceration in the male partner (2.6). Hormonal contraception use was not associated with HIV transmission or acquisition. CONCLUSIONS: Our findings underscore the need for integrating HIV services with care for genital abnormalities. Barriers (eg, cost of training, demand creation, advocacy, and client education; provider time; and clinic space) to joint HIV/STI testing need to be considered and addressed.

BACKGROUND: Antiretroviral therapy (ART) efficacy for HIV prevention among discordant couples has been demonstrated in clinical trials. Effectiveness outside of research settings is less well understood. METHODS: HIV-discordant couples were enrolled in couples' testing and follow-up at 20 government clinics in Kigali from 2010 to 2014. We performed viral linkage analysis on seroconverting couples to determine infection sources (intracouple vs. extracouple). Antiretroviral therapy use in index partners was collected at baseline and during follow-up by self-report with verification of government medical records. RESULTS: A total of 3777 HIV-discordant couples were identified and followed up at government health clinics. Fifty-four incident HIV infections were identified, of which 36 were confirmed linked to the index partner, 4 were unlinked, and 14 were unknown. Among the 50 linked or unknown transmission pairs, 38% occurred among couples in which the index partner was on ART (HIV incidence rate of 0.63/100 person-years), whereas 62% occurred among couples in which the index partner was not on ART (HIV incidence rate of 5.51/100 person-years; adjusted rate ratio, 6.9). HIV acquisition was higher in women than in men with non-ART using index partners (P < 0.001). CONCLUSIONS: Couples in a government clinic couples' HIV testing and follow-up program in Rwanda had an 89% reduction in HIV incidence when index partners were using ART, slightly lower than efficacy estimates from randomized trials. Antiretroviral therapy for prevention should be prioritized for key populations including discordant couples identified via couples' voluntary counseling and testing, with increased efforts to improve uptake, adherence, and viral load monitoring.

Violence against women is a known risk factor for HIV and affects female sex workers (FSW) in sub-Saharan Africa. Little is known about the magnitude and determinants of violence against FSW in Zambia, where HIV and gender-based violence prevalence are high. We conducted a cross-sectional study, using multivariable logistic regression, to determine the prevalence and correlates of client-initiated physical violence among 419 FSW in Lusaka and Ndola. The prevalence of client-initiated physical violence was 39%. The odds of violence were higher for FSW who: lived in Lusaka, recruited clients from the street, serviced clients in the clients' homes, had a physically forced sexual debut, and had a higher client volume. Our results call for safer working spaces for FSW and violence prevention interventions for their male clients.

INTRODUCTION: Postpartum family planning (PPFP) is critical to reduce maternal-child mortality, abortion and unintended pregnancy. As in most countries, the majority of PP women in Rwanda have an unmet need for PPFP. In particular, increasing use of the highly effective PP long-acting reversible contraceptive (LARC) methods (the intrauterine device (IUD) and implant) is a national priority. We developed a multilevel intervention to increase supply and demand for PPFP services in Kigali, Rwanda. METHODS: We implemented our intervention (which included PPFP promotional counselling for clients, training for providers, and Ministry of Health stakeholder involvement) in six government health facilities from August 2017 to October 2018. While increasing knowledge and uptake of the IUD was a primary objective, all contraceptive method options were discussed and made available. Here, we report a secondary analysis of PP implant uptake and present already published data on PPIUD uptake for reference. RESULTS: Over a 15-month implementation period, 12 068 women received PPFP educational counselling and delivered at a study facility. Of these women, 1252 chose a PP implant (10.4% uptake) and 3372 chose a PPIUD (27.9% uptake). On average providers at our intervention facilities inserted 83.5 PP implants/month and 224.8 PPIUDs/month. Prior to our intervention, 30 PP implants/month and 8 PPIUDs/month were inserted at our selected facilities. Providers reported high ease of LARC insertion, and clients reported minimal insertion anxiety and pain. CONCLUSIONS: PP implant and PPIUD uptake significantly increased after implementation of our multilevel intervention. PPFP methods were well received by clients and providers.

HIV-incidence studies are used to identify at-risk populations for HIV-prevention trials and interventions, but loss to follow-up (LTFU) can bias results if participants who remain differ from those who drop out. We investigated the incidence of and factors associated with LTFU among Zambian female sex workers (FSWs) in an HIV-incidence cohort from 2012 to 2017. Enrolled participants returned at month one, month three and quarterly thereafter. FSWs were considered LTFU if they missed six consecutive months, or if their last visit was six months before the study end date. Of 420 FSWs, 139 (33%) were LTFU at a rate of 15.7 per 100 person years. In multivariable analysis, LTFU was greater for FSWs who never used alcohol, began sex work above the age of consent, and had a lower volume of new clients. Our study appeared to retain FSWs in most need of HIV-prevention services offered at follow-up.

BACKGROUND: When integrated with couples' voluntary HIV counselling and testing (CVCT), family planning including long acting reversible contraceptives (LARC) addresses prongs one and two of prevention of mother-to-child transmission (PMTCT). METHODS: In this observational study, we enrolled equal numbers of HIV concordant and discordant couples in four rural and four urban clinics, with two Catholic and two non-Catholic clinics in each area. Eligible couples were fertile, not already using a LARC method, and wished to limit or delay fertility for at least 2 years. We provided CVCT and fertility goal-based family planning counselling with the offer of LARC and conducted multivariate analysis of clinic, couple, and individual predictors of LARC uptake. RESULTS: Of 1290 couples enrolled, 960 (74%) selected LARC: Jadelle 5-year implant (37%), Implanon 3-year implant (26%), or copper intrauterine device (IUD) (11%). Uptake was higher in non-Catholic clinics (85% vs. 63% in Catholic clinics, p < 0.0001), in urban clinics (82% vs. 67% in rural clinics, p < 0.0001), and in HIV concordant couples (79% vs. 70% of discordant couples, p = .0005). Religion of the couple was unrelated to clinic religious affiliation, and uptake was highest among Catholics (80%) and lowest among Protestants (70%) who were predominantly Pentecostal. In multivariable analysis, urban location and non-Catholic clinic affiliation, Catholic religion of woman or couple, younger age of men, lower educational level of both partners, non-use of condoms or injectable contraception at enrollment, prior discussion of LARC by the couple, and women not having concerns about negative side effects of implant were associated with LARC uptake. CONCLUSIONS: Fertility goal-based LARC recommendations combined with couples' HIV counselling and testing resulted in a high uptake of LARC methods, even among discordant couples using condoms for HIV prevention, in Catholic clinics, and in rural populations. This model successfully integrates prevention of HIV and unplanned pregnancy.
