RESUMO

We evaluated hair tenofovir (TFV) concentrations as an adherence metric for HIV pre-exposure prophylaxis (PrEP) during pregnancy and postpartum and compared hair levels with tenofovir-diphosphate (TFV-DP) levels in dried blood spots (DBS). Overall, 152 hair samples from 102 women and 36 hair-DBS paired samples from 29 women were collected from a subset of women in a cluster randomized trial. Having a partner known to be living with HIV was associated with higher hair TFV levels (p<0.001). Hair TFV concentrations were strongly correlated with DBS TFV-DP levels (r=0.76, p<0.001), indicating hair as promising cumulative adherence metric for perinatal PrEP assessment.

RESUMO

BACKGROUND: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in pregnancy contribute to adverse perinatal outcomes. We identified predictors of CT and/or NG infection among pregnant Kenyan women. METHODS: Women without HIV were enrolled at 2 antenatal clinics in Western Kenya. Both CT and NG were assessed using endocervical samples for nucleic acid amplification tests. Poisson regression models were used to evaluate potential CT/NG risk factors. Classification and regression trees were generated to evaluate the joint effects of predictors. RESULTS: Overall, 1276 women had both CT and NG assessments. Women enrolled at a median of 26 weeks' gestation (interquartile range, 22-31 weeks), median age was 22 years (interquartile range, 19-27 years), and 78% were married. In total, 98 (7.7%) tested positive for CT/NG: 70 (5.5%) for CT and 32 (2.5%) for NG, 4 of whom (0.3%) had coinfections. Two-thirds (66%) of CT/NG cases were asymptomatic and would have been missed with only syndromic management. Risk factors of CT/NG included age <22 years, crowded living conditions, being unmarried, being in partnerships for <1 year, abnormal vaginal discharge, sexually transmitted infection history, and Trichomonas vaginalis diagnosis ( P < 0.1). Classification and regression tree analyses identified unmarried women <22 years in relationships for <1 year as 6.1 times more likely to have CT/NG compared with women without these characteristics (26% vs. 6%, adjusted prevalence ratio = 6.1, 95% confidence interval = 3.55-10.39, P < 0.001). CONCLUSIONS: Chlamydia trachomatis / Neisseria gonorrhoeae was frequently asymptomatic and common among young unmarried women in newer partnerships in this cohort. Integrating CT/NG testing into routine antenatal care may be beneficial, especially for young women in Kenya.

RESUMO

PURPOSE OF REVIEW: To provide an overview of the current state of HIV pre-exposure prophylaxis (PrEP) delivery via private sector pharmacies globally, to discuss the context-specific factors that have influenced the design and implementation of different pharmacy-based PrEP delivery models in three example settings, and to identify future research directions. RECENT FINDINGS: Multiple high- and low-income countries are implementing or pilot testing PrEP delivery via private pharmacies using a variety of delivery models, tailored to the context. Current evidence indicates that pharmacy-based PrEP services are in demand and generally acceptable to clients and pharmacy providers. Additionally, the evidence suggests that with proper training and oversight, pharmacy providers are capable of safely initiating and managing clients on PrEP. The delivery of PrEP services at private pharmacies also achieves similar levels of PrEP initiation and continuation as traditional health clinics, but additionally reach individuals underserved by such clinics (e.g., young men; minorities), making pharmacies well-positioned to increase overall PrEP coverage. Implementation of pharmacy-based PrEP services will look different in each context and depend not only on the state of the private pharmacy sector, but also on the extent to which key needs related to governance, financing, and regulation are addressed. Private pharmacies are a promising delivery channel for PrEP in diverse settings. Countries with robust private pharmacy sectors and populations at HIV risk should focus on aligning key areas related to governance, financing, and regulation that have proven critical to pharmacy-based PrEP delivery while pursuing an ambitious research agenda to generate information for decision-making. Additionally, the nascency of pharmacy-based PrEP delivery in both high- and low-and-middle-income settings presents a prime opportunity for shared learning and innovation.

RESUMO

BACKGROUND: Over one-third of people living with HIV (PLH) in Ukraine are not on treatment. Index testing services, which link potentially exposed partners (named partners) of known PLH (index patients) with testing and treatment services, are being scaled in Ukraine and could potentially close this gap. METHODS: This retrospective study included patient data from 14,554 adult PLH who initiated antiretroviral treatment (ART) between October 2018 and May 2021 at one of 35 facilities participating in an intervention to strengthen index testing services. Mixed effects modified Poisson models were used to assess differences between named partners and other ART initiators, and an interrupted time series (ITS) analysis was used to assess changes in ART initiation over time. RESULTS: Compared to other ART initiators, named partners were significantly less likely to have a confirmed TB diagnosis (aRR = 0.56, 95% CI = 0.40, 0.77, p < 0.001), a CD4 count less than 200 cells/mm3 (aRR = 0.84, 95% CI = 0.73, 0.97, p = 0.017), or be categorized as WHO HIV stage 4 (aRR = 0.68, 9% CI = 0.55, 0.83, p < 0.001) at the time of ART initiation, and were significantly more likely to initiate ART within seven days of testing for HIV (aRR = 1.36, 95% CI = 1.22, 1.50, p < 0.001). Our ITS analysis showed a modest 2.34% (95% CI = 0.26%, 4.38%; p = 0.028) month-on-month reduction in mean ART initiations comparing the post-intervention period to the pre-intervention period, although these results were likely confounded by the COVID epidemic. CONCLUSION: Our findings suggest that index testing services may be beneficial in bringing PLH into treatment at an earlier stage of HIV disease and decreasing delays between HIV testing and ART initiation, potentially improving patient outcomes and retention in the HIV care cascade.

RESUMO

BACKGROUND: Evidence gaps remain regarding the influence of prenatal psychosocial factors on adverse pregnancy outcomes. OBJECTIVE: The objective of this study is to evaluate relationships between psychosocial factors and adverse perinatal outcomes among Kenyan women. METHODS: We analysed data from a prospective cohort study enrolling HIV-negative women in pregnancy (NCT03070600) in 20 antenatal clinics in Western Kenya. Study nurses assessed depressive symptoms using the Center for Epidemiologic Studies Depression Scale (CESD-10), social support using the Medical Outcomes Survey scale (MOS-SSS), intimate partner violence (IPV) with the Hurt, Insult, Threaten, Scream scale (HITS), and pregnancy outcomes at 6 weeks postpartum. Cox proportional hazards models were used to evaluate relationships between depressive symptoms (moderate-to-severe [MSD, CESD-10 ≥10] and mild-to-severe [Mild-SD, CESD-10 ≥5]), low social support (MOS-SSS <72), and IPV (HITS ≥10) with adverse perinatal outcomes of pregnancy loss, stillbirth, preterm birth (PTB), small for gestational age, and neonatal mortality. We also estimated the population attributable risk. RESULTS: Among 4153 women, 23.9% (n = 994) had MSD, 54.7% (n = 2273) mild-SD, 37.3% (n = 1550) low social support, and 7.8% (n = 323) experienced IPV. Pregnancy loss was 5-fold higher among women with MSD (adjusted hazard ratio [HR] 5.04, 95% confidence interval [CI] 2.44, 10.42); 37.4% of losses were attributable to MSD. Mild-SD was associated with PTB (HR 1.39, 95% CI 1.03, 1.87). Stillbirth risk more than doubled among women reporting low social support (HR 2.37, 95% CI 1.14, 4.94). CONCLUSIONS: Adverse perinatal outcomes were common and associated with prenatal depressive symptoms and low social support in this large cohort of Kenyan mother-infant pairs.

RESUMO

ABSTRACT: Public health spending is important for managing increases in sexually transmitted diseases (STDs) in the United States. Although previous studies suggest that a beneficial link exists between public health spending and changes in STD rates, there have been no systematic reviews synthesizing existing evidence regarding the association for STDs at the population level. The objective of this study was to synthesize evidence from studies that assessed the associations between general and STD-specific public health spending and STD rates. We conducted a systematic review using Ovid-Medline, EMBASE, CINAHL, Cochrane Library, Web of Science, and EconLit for relevant studies that examined the association between public health spending and gonorrhea, syphilis, chlamydia, and chancroid rates following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 5 articles (2 regarding general public health spending and 3 regarding STD-specific public health spending) met our inclusion criteria. There was a significant decrease in gonorrhea, syphilis, chlamydia, and chancroid rates associated with increased public health spending. We also found that STD-specific public health spending has a greater effect on STD rates compared with general public health spending. Our review provides evidence that increases in general and STD-specific public health spending are associated with a reduction of STD rates. Such research regarding estimates of the impact of STD prevention spending can help policy makers identify priority funding areas and inform health resource allocation decisions.

RESUMO

PURPOSE OF REVIEW: Multiple tools exist to support the primary prevention of HIV in pregnant and postpartum women; however, there are opportunities to enhance their use and impact. This review summarizes the current status of HIV prevention tools and existing gaps and opportunities to improve their use along the pregnancy care continuum. RECENT FINDINGS: HIV screening efforts have steadily improved with close to universal screening of pregnant women in several East and Southern African countries. Strategies to implement partner testing through the distribution of HIV self-test kits are promising though linkage to care remains challenging. Syphilis screening rates are increasing though detection of other sexually transmitted infections could benefit from improved diagnostic capacity. Male and female condoms are rarely used and are often not the optimal tool of choice during pregnancy. Oral pre-exposure prophylaxis (PrEP) is a promising tool, although barriers such as the need for daily adherence, side effects, and stigma may limit its use. There is a growing pipeline of PrEP agents with alternative delivery platforms that might suit women's preferences better and supports the notion that choice is vital to improving HIV prevention coverage during the pregnancy-postpartum continuum. Clear guidance on which tools to use and how to use them, safety data supporting their use, and surveillance data documenting the scale and effectiveness of the tools will be imperative in establishing a path to more impactful prevention efforts among pregnant and postpartum women.

RESUMO

We sought to understand influences on PrEP uptake among Kenyan adolescent girls and young women (AGYW) whose decision on PrEP use was misaligned with their risk for HIV acquisition. In-depth interviews were conducted with 47 Kenyan HIV-negative AGYW aged 15-24 years who were offered PrEP during routine maternal and child health and family planning services. AGYW were sampled from two groups (1) declined PrEP and had ≥1 sexual partner(s) of unknown HIV status and (2) initiated PrEP and reported having one HIV-negative partner. AGYW with HIV-negative partners initiated PrEP due to known or suspected infidelity. AGYW with partners of unknown HIV status recognized PrEP as a helpful HIV prevention tool, yet worried about partner reactions and prioritized avoiding uncomfortable or unsafe situations over PrEP. Among pregnant AGYW, the responsibility of motherhood and providing a future for one's family, through staying healthy and remaining HIV-free, was a strong PrEP use motivator. Among AGYW who desired future motherhood, fears that PrEP could negatively impact fertility or reduce contraceptive effectiveness led to declining PrEP. Peers positively influenced PrEP decision-making, especially personally knowing a PrEP user. Strategies are needed to enhance messaging and delivery approaches that are tailored to AGYW, including peer-led strategies.

RESUMO

INTRODUCTION: Pregnant women in sub-Saharan Africa have high risk of HIV acquisition, yet approaches for measuring maternal HIV incidence using routine surveillance systems are undefined. We used programmatic data from routine antenatal care (ANC) HIV testing in Botswana to measure real-world HIV incidence during pregnancy. METHODS: From January 2018 to September 2019, the Botswana Ministry of Health and Wellness implemented an HIV testing program at 139 ANC clinics. The program captured information on testers' age, testing date and result, and antiretroviral treatment (ART) initiation. In our analysis, we excluded individuals who previously tested HIV-positive prior to their first ANC visit. We defined incident HIV infection as testing HIV-positive at an ANC visit after a prior HIV-negative result within ANC. RESULTS: Overall, 29,570 pregnant women (median age 26 years, IQR 22-31) tested for HIV at ANC clinics: 3% (836) tested HIV-positive at their first recorded ANC visit and 97% tested HIV-negative (28,734). Of those who tested HIV-negative, 28% (7940/28,734) had a repeat HIV test recorded at ANC. The median time to HIV re-testing was 92 days (IQR 70-112). In total, 17 previously undiagnosed HIV infections were detected (HIV incidence 8 per 1000 person-years, 95% CI 0.5-1.3). ART initiation among women newly diagnosed with HIV at ANC (853) was 88% (671/762). CONCLUSIONS: In Botswana, real-world HIV incidence among pregnant women at ANC remains above levels of HIV epidemic control (≤ 1 per 1000 person-years). This study shows how HIV programmatic data can answer timely population-level epidemiological questions and inform ongoing implementation of HIV prevention and treatment programs.

RESUMO

Understanding in utero transfer of antiretrovirals is critical for interpreting safety. Hair levels measure cumulative exposure. We measured tenofovir (TFV) concentrations in hair at delivery among women living with human immunodeficiency virus receiving TFV disoproxil fumarate-based treatment and their infants, using liquid chromatography-tandem mass spectrometry. Among 103 mother-infant pairs, the mean log10 ratio of infant-to-maternal TFV levels was 1.08 (95% confidence interval, .97-1.20). TFV transfer was 60% lower from mothers who had preterm compared with term deliveries and 42% lower from mothers who had cesarean compared with vaginal deliveries. Like prior studies assessing transfer via short-term measures (plasma, cord blood, amniotic fluid), we found high cumulative transfer using hair.

RESUMO

BACKGROUND: During HIV retesting in antenatal and preexposure prophylaxis (PrEP) care, discrepant results occur, but guidelines are lacking. METHODS: In a Kenyan trial implementing antenatal PrEP, if 1 test is reactive, a second is performed; if discrepant, both are repeated; if persistently discrepant, DNA polymerase chain reaction (PCR) is performed. RESULTS: Among 4451 women, 23 265 HIV retesting sessions were performed; 14 (0.06%, 95% confidence interval, 0.03%-0.10%) had discrepant results among 10 individuals; in all 10 initial cases, PCR was negative. CONCLUSIONS: Discrepant rapid tests are an expected, rare, and important challenge for antenatal care HIV retesting, with and without PrEP. CLINICAL TRIALS REGISTRATION: NCT03070600.

RESUMO

ABSTRACT: Among 130,161 HIV testing records from unique individuals at 149 programmatic sites in Botswana, frequency of detecting undiagnosed HIV infection within emergency departments (EDs) was 4.7% (455/9695), 2-fold higher than other clinic-based HIV counseling and testing. Men and noncitizens less frequently initiated same-day antiretroviral therapy after testing HIV positive within emergency departments.

RESUMO

In a pre-exposure prophylaxis program for Kenyan women, we detected tenofovir-diphosphate in 61% (125/201) of randomly selected dried blood spots collected at the first follow-up visit. Tenofovir-diphosphate was detected more frequently among women who had partners living with human immunodeficiency virus, who were not pregnant, and who were ≥24 years.

RESUMO

INTRODUCTION: In Kenya, pre-exposure prophylaxis (PrEP) for HIV prevention is almost exclusively delivered at HIV clinics. Developing novel PrEP delivery models is important for increasing the reach of PrEP. Delivery of PrEP through pharmacies is one approach utilized in the US to improve accessibility. Retail pharmacies are commonly used as a first-line access point for medical care in Kenya, but have not been utilized for PrEP delivery. We conducted a collaborative consultative meeting of stakeholders to develop a care pathway for pharmacy-based PrEP delivery in Kenya. METHODS: In January 2020, we held a one-day meeting in Nairobi with 36 stakeholders from PrEP regulatory, professional, healthcare service delivery, civil society, and research organizations. Attendees reviewed a theory of change model, results from formative qualitative research with pharmacy providers and clients, and anticipated core components of pharmacy-based PrEP delivery: counseling, HIV testing, prescribing, and dispensing. Stakeholders participated in small and large group discussions to identify potential challenges and solutions. We synthesized the key findings from these discussions. RESULTS: Stakeholders were enthusiastic about a model for pharmacy-based PrEP delivery. Potential challenges identified included insufficient pharmacy provider knowledge and skills, regulatory hurdles to providing affordable HIV testing at pharmacies, and undefined pathways for PrEP procurement. Potential solutions identified included having pharmacy providers complete the Kenya Ministry of Health-approved PrEP training, use of a PrEP prescribing checklist with remote clinician oversight and provider-assisted HIV self-testing, and having the government provide PrEP and HIV self-testing kits to pharmacies during a pilot test. A care pathway was developed over the course of the meeting. CONCLUSIONS: PrEP delivery stakeholders in Kenya were strongly supportive of developing and testing a model for pharmacy-based PrEP delivery to increase PrEP access. We collaboratively developed a care pathway for pilot testing that has the potential to expand PrEP delivery options in Kenya and other similar settings.

RESUMO

BACKGROUND: Young women account for a disproportionate fraction of new HIV infections in Africa and are a priority population for HIV prevention, including implementation of preexposure prophylaxis (PrEP). The overarching goal of this project was to demonstrate the feasibility of integrating PrEP delivery within routine family planning (FP) clinics to serve as a platform to efficiently reach at-risk adolescent girls and young women (AGYW) for PrEP in HIV high-burden settings. METHODS AND FINDINGS: The PrEP Implementation in Young Women and Adolescents (PrIYA) program is a real-world implementation program to demonstrate integration of PrEP delivery for at-risk AGYW in FP clinics in Kisumu, Kenya. Between November 2017 and June 2018, women aged 15 to 45 from the general population seeking FP services at 8 public health clinics were universally screened for HIV behavioral risk factors and offered PrEP following national PrEP guidelines. We evaluated PrEP uptake and continuation, and robust Poisson regression methods were used to identify correlates of uptake and early continuation of PrEP, with age included as a one-knot linear spline. Overall, 1,271 HIV-uninfected women accessing routine FP clinics were screened for PrEP; the median age was 25 years (interquartile range [IQR]: 22-29), 627 (49%) were <24 years old, 1,026 (82%) were married, more than one-third (34%) had partners of unknown HIV status, and the vast majority (n = 1,200 [94%]) reported recent condom-less sex. Of 1,271 women screened, 278 (22%) initiated PrEP, and 114 (41%) returned for at least one refill visit after initiation. PrEP uptake was independently associated with reported male-partner HIV status (HIV-positive 94%, unknown 35%, HIV-negative 8%; p < 0.001) and marital status (28% unmarried versus married 21%; p = 0.04), and a higher proportion of women ≥24 years (26%; 191/740) initiated PrEP compared to 16% (87/531) of young women <24 years (p < 0.001). There was a moderate and statistically non-significant unadjusted increase in PrEP uptake among women using oral contraception pills (OCPs) compared to women using injectable or long-acting reversible contraception methods (OCP 28% versus injectable/implants/intrauterine devices [IUDs] 18%; p = 0.06). Among women with at least one post-PrEP initiation follow-up visit (n = 278), no HIV infection was documented during the project period. Overall, continuation of PrEP use at 1, 3, and 6 months post initiation was 41%, 24%, and 15%, respectively. The likelihood for early continuation of PrEP use (i.e., return for at least one PrEP refill within 45 days post initiation) was strongly associated with reported male-partner HIV status (HIV-positive 67%, -negative 39%, unknown 31%; overall effect p = 0.001), and a higher proportion of women ≥24 years old continued PrEP at 1 month compared with young women <24 years old (47% versus 29%; p = 0.002). For women ≥24 years old, the likelihood to continue PrEP use at 1 month post initiation increased by 3% for each additional year of a woman's age (adjusted prevalence ratio [PR]: 1.03; 95% confidence interval [CI]: 1.01-1.05; p = 0.01). In contrast, for women <24 years old, the likelihood of continuing PrEP for each additional year of a woman's age was high in magnitude (approximately 6%) but statistically non-significant (adjusted PR: 1.06; 95% CI: 0.97-1.16; p = 0.18). Frequently reported reasons for discontinuing PrEP were low perceived risk of HIV (25%), knowledge that partner was HIV negative (24%), experiencing side effects (20%), and pill burden (17%). Study limitations include lack of qualitative work to provide insights into women's decision-making on PrEP uptake and continuation, the small number of measured covariates imposed by the program data, and a nonrandomized design limiting definitive ascertainment of the robustness of a PrEP-dedicated nurse-led implementation strategy. CONCLUSIONS: In this real-world PrEP implementation program in Kenya, integration of universal screening and counseling for PrEP in FP clinics was feasible, making this platform a potential "one-stop" location for FP and PrEP. There was a high drop-off in PrEP continuation, but a subset of women continued PrEP use at least through 1 month, possibly indicating further reflection or decision-making on PrEP use. Greater efforts to support PrEP normalization and persistence for African women are needed to help women navigate their decisions about HIV prevention preferences as their reproductive goals and HIV vulnerability evolve.

OBJECTIVES: We evaluated the relationship of sexually transmitted infections (STIs) and genital infections during pregnancy and subsequent risk for infant mortality and stillbirth. METHODS: This was a nested longitudinal analysis using data from a study of peripartum HIV acquisition in Kenya. In the parent study, HIV-uninfected women were enrolled during pregnancy and followed until 9 months postpartum. For this analysis, women who tested positive for HIV at any point, had a non-singleton pregnancy or a spontaneous abortion <20 weeks were excluded. At enrolment, laboratory methods were used to screen for bacterial vaginosis (BV), vaginal yeast, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV). Syphilis was diagnosed using rapid plasma reagin testing and genital ulcer disease (GUD) identified by clinical examination. Treatment of laboratory-confirmed STIs and syndromic management was provided per Kenyan national guidelines. Predictors of stillbirth and infant mortality were determined using logistic regression and Cox proportional hazards models. RESULTS: Overall, among 1221 women, 55% had STIs or genital infections detected: vaginal yeast (25%), BV (22%), TV (6%), CT (5%), NG (2%) and syphilis (1%). Among women with STIs/genital infections (n=592), 34% had symptoms. Overall, 19/1221 (2%) women experienced stillbirths. Among 1202 live births, 34 infant deaths occurred (incidence 4.0 deaths per 100 person-years, 95% CI 2.8 to 5.5). After adjustment for maternal age, education and study site, stillbirth was associated with maternal GUD (adjusted OR=9.19, 95% CI1.91 to 44.35, p=0.006). Maternal NG was associated with infant mortality (adjusted HR=3.83, 95% CI1.16 to 12.68, p=0.028); there was some evidence that maternal CT was associated with infant mortality. Stillbirth or infant mortality were not associated with other genital infections. CONCLUSIONS: STIs and genital infections were common, frequently asymptomatic and some associated with stillbirth or infant mortality. Expediting diagnosis and treatment of STIs in pregnancy may improve infant outcomes.

RESUMO

BACKGROUND: Male partner antenatal clinic (ANC) attendance may improve maternal uptake of maternal child health (MCH) services. METHODS: We conducted a cross-sectional survey of mother-infant pairs attending week-6 or month-9 infant immunizations at 120 high-volume MCH clinics throughout Kenya. Clinics were selected using probability proportionate to size sampling. Women were interviewed using structured questionnaires and clinical data was verified using MCH booklets. Among married women, survey-weighted logistic regression models accounting for clinic-level clustering were used to compare outcomes by male ANC attendance and to identify its correlates. RESULTS: Among 2521 women attending MCH clinics and had information on male partner ANC attendance, 2141 (90%) were married of whom 806 (35%) had male partners that attended ANC. Among married women, male partner ANC attendance was more frequent among women with higher education, women who requested their partners to attend ANC, had male partners with higher education, did not report partner violence, and had disclosed their HIV status (p < 0·001 for each). Additionally, male ANC attendance was associated with higher uptake of ANC visits [adjusted Odds Ratio (AOR) = 1·67, 95% confidence interval (CI) 1·36-2·05,], skilled delivery (AOR = 2·00, 95% CI 1·51-2·64), exclusive breastfeeding (AOR = 1·70, 95% CI 1·00-2·91), infant Bacille Calmette Guerin (BCG) immunization (AOR = 3·59, 95% CI 1·00-12·88), and among HIV-infected women, antiretroviral drugs (aOR = 6·16, 95% CI 1·26-30·41). CONCLUSION: Involving male partners in MCH activities amplifies benefits of MCH services by engaging partner support for maternal uptake of services.

RESUMO

Antenatal register data from 62 clinics in 5 regions of Kenya were used to estimate women with human immunodeficiency virus (HIV) risk (partner HIV status, syphilis). With individual risk-guided preexposure prophylaxis (PrEP) offer in all regions, 39% of pregnant women would be offered PrEP nationally. Offering PrEP to all women in high-prevalence regions reached 26% of the pregnant women.

RESUMO

BACKGROUND: Prevention of mother-to-child HIV transmission (PMTCT) programs usually test pregnant women for HIV without involving their partners. Non-disclosure of maternal HIV status to male partners may deter utilization of PMTCT interventions since partners play a pivotal role in decision-making within the home including access to and utilization of health services. METHODS: Mothers attending routine 6-week and 9-month infant immunizations were enrolled at 141 maternal and child health (MCH) clinics across Kenya from June-December 2013. The current analysis was restricted to mothers with known HIV status who had a current partner. Multivariate logistic regression models adjusted for marital status, relationship length and partner attendance at antenatal care (ANC) were used to determine correlates of HIV non-disclosure among HIV-uninfected and HIV-infected mothers, separately, and to evaluate the relationship of non-disclosure with uptake of PMTCT interventions. All analyses accounted for facility-level clustering, RESULTS: Overall, 2522 mothers (86% of total study population) met inclusion criteria, 420 (17%) were HIV-infected. Non-disclosure of HIV results to partners was higher among HIV-infected than HIV-uninfected women (13% versus 3% respectively, p < 0.001). HIV-uninfected mothers were more likely to not disclose their HIV status to male partners if they were unmarried (adjusted odds ratio [aOR] = 3.79, 95% CI: 1.56-9.19, p = 0.004), had low (≤KSH 5000) income (aOR = 1.85, 95% CI: 1.00-3.14, p = 0.050), experienced intimate partner violence (aOR = 3.65, 95% CI: 1.84-7.21, p < 0.001) and if their partner did not attend ANC (aOR = 4.12, 95% CI: 1.89-8.95, p < 0.001). Among HIV-infected women, non-disclosure to male partners was less likely if women had salaried employment (aOR = 0.42, 95%CI: 0.18-0.96, p = 0.039) and each increasing year of relationship length was associated with decreased likelihood of non-disclosure (aOR = 0.90, 95% CI: 0.82-0.98, p = 0.015 for each year increase). HIV-infected women who did not disclose their HIV status to partners were less likely to uptake CD4 testing (aOR = 0.32, 95% CI: 0.15-0.69, p = 0.004), to use antiretrovirals (ARVs) during labor (OR = 0.38, 95% CI 0.15-0.97, p = 0.042), or give their infants ARVs (OR = 0.08, 95% CI 0.02-0.31, p < 0.001). CONCLUSION: HIV-infected women were less likely to disclose their status to partners than HIV-uninfected women. Non-disclosure was associated with lower use of PMTCT services. Facilitating maternal disclosure to male partners may enhance PMTCT uptake.

RESUMO

Background: Tenofovir disoproxil fumarate (TDF) is commonly used in antiretroviral treatment (ART) and pre-exposure prophylaxis regimens. We evaluated the relationship between adverse perinatal outcomes and prenatal TDF use. Methods: Longitudinal data were analyzed from human immunodeficiency virus (HIV)-infected women who became pregnant during 2 HIV prevention studies conducted among HIV-serodiscordant couples in Kenya and Uganda. Pregnancies included were singleton, not terminated by an induced abortion, and had documented 3-drug ART use. Multivariate generalized estimating equation models were used to determine the association of prenatal TDF and perinatal outcomes. Results: The most frequent ART regimens were TDF/3TC/EFV (39%) and AZT/3TC/NVP (34%); 49% of pregnancies had prenatal TDF exposure and 6% used a protease inhibitor. Neonatal death, preterm birth, and pregnancy loss occurred in 2%, 8%, and 12% of pregnancies, respectively. No differences were observed between pregnancies with and without exposure to TDF in the frequency of pregnancy loss (adjusted prevalence rate ratio [aPRR] 1.19, P = .8) or neonatal death (aPRR 0.68, P = .6). Preterm birth occurred less frequently among pregnancies exposed to TDF (aPRR, 0.34, P = .02). Conclusion: Maternal TDF use did not adversely affect perinatal outcomes.
