Abstract
Peer support services are increasingly being integrated in programmes for the prevention of mother-to-child HIV transmission (PMTCT). We aimed to evaluate the effect of a peer-mother interactive programme on PMTCT outcomes among pregnant women on anti-retroviral treatment (ART) in routine healthcare in Dar es Salaam, Tanzania. Twenty-three health facilities were cluster-randomized to a peer-mother intervention and 24 to a control arm. We trained 92 ART experienced women with HIV to offer peer education, adherence and psychosocial support to women enrolling in PMTCT care at the intervention facilities. All pregnant women who enrolled in PMTCT care at the 47 facilities from 1st January 2018 to 31st December 2019 were identified and followed up to 31st July 2021. The primary outcome was time to ART attrition (no show >90 days since the scheduled appointment, excluding transfers) and any difference in one-year retention in PMTCT and ART care between intervention and control facilities. Secondary outcomes were maternal viral suppression (<400 viral copies/mL) and mother-to-child HIV transmission (MTCT) by ≥12 months post-partum. Analyses were done using Kaplan Meier and Cox regression (ART retention/attrition), generalized estimating equations (viral suppression) and random effects logistic regression (MTCT); reporting rates, proportions and 95% confidence intervals (CI). There were 1957 women in the peer-mother and 1384 in the control facilities who enrolled in routine PMTCT care during 2018-2019 and were followed for a median [interquartile range (IQR)] of 23 [10, 31] months. Women in both groups had similar median age of 30 [IQR 25, 35] years, but differed slightly with regard to proportions in the third pregnancy trimester (14% versus 19%); advanced HIV (22% versus 27%); and ART naïve (55% versus 47%). Peer-mother facilities had a significantly lower attrition rate per 1000 person months (95%CI) of 14 (13, 16) versus 18 (16, 19) and significantly higher one-year ART retention (95%CI) of 78% (76, 80) versus 74% (71, 76) in un-adjusted analyses, however in adjusted analyses the effect size was not statistically significant [adjusted hazard ratio of attrition (95%CI) = 0.85 (0.67, 1.08)]. Viral suppression (95%CI) was similar in both groups [92% (91, 93) versus 91% (90, 92)], but significantly higher among ART naïve women in peer-mother [91% (89, 92)] versus control [88% (86, 90)] facilities. MTCT (95%CI) was similar in both groups [2.2% (1.4, 3.4) versus 1.5% (0.7, 2.8)]. In conclusion, we learned that integration of peer-mother services in routine PMTCT care improved ART retention among all women and viral suppression among ART naïve women but had no significant influence on MTCT.

Abstract
Research in rapidly evolving policy contexts can lead to the following ethical challenges for sponsors and researchers: the study's standard of care can become different than what patients outside the study receive, there may be political or other pressure to move ahead with unproven interventions, and new findings or revised policies may decrease the relevance of ongoing studies. These ethical challenges are considerable, but not unprecedented. In this article, we review the case of a multinational, randomized, controlled perinatal HIV prevention trial, the "PROMISE" (Promoting Maternal Infant Survival Everywhere) study. PROMISE compared the relative efficacy and safety of interventions to prevent mother to child transmission of HIV. The sponsor engaged an independent international ethics panel to address controversy about the study's standard of care and relevance as national and international guidelines changed. This ethics panel concluded that continuing the PROMISE trial as designed was ethically permissible because: (1) participants in all arms received interventions that were effective, and there was insufficient evidence about whether one intervention was more effective or safer than the other, and (2) data from PROMISE could be useful for a diverse range of stakeholders. In general, trials designed to inform rapidly evolving policy issues should develop mechanisms to revisit social value while recognizing that the value of research varies for diverse stakeholders with legitimate reasons to weigh evidence differently. We conclude by providing four reasons that trials may depart from the standard of care after a change in policy, while remaining ethically justifiable, and by suggesting how to improve existing trial oversight mechanisms to address evolving social value.

Abstract
BACKGROUND HIV status disclosure by pregnant women living with HIV (PWLHIV) to their male partners is associated with improved maternal and infant outcomes. Understanding relationship factors associated with nondisclosure of HIV status by PWLHIV to their partners can inform the design of interventions to facilitate disclosure. METHODS We conducted a cross-sectional study using enrollment data from 500 PWLHIV unaware of their male partners' HIV status and participating in a randomized clinical trial assessing secondary distribution of HIV self-testing kits in Kampala, Uganda. The primary outcome was women's HIV status nondisclosure to their partners. We conducted univariate and multivariate binomial regressions to assess the association between baseline sociodemographic, HIV history, and relationship characteristics with HIV status nondisclosure. RESULTS 68.2% of the 500 PWLHIV had not disclosed their HIV status to their partner(s). Factors associated with higher likelihood of nondisclosure included relationship duration <1 year [adjusted prevalence ratio (aPR = 1.25); 95% confidence interval (CI): 1.02 to 1.54], being in a polygamous relationship (aPR = 1.21; 95% CI: 1.07 to 1.36), unmarried (aPR = 1.20; 95% CI: 1.07 to 1.35), uncertainty about whether their partner had ever tested for HIV (aPR = 1.55; 95% CI: 1.28 to 1.88), and a lack of social support from people aware of their status (aPR = 1.32; 95% CI: 1.18 to 1.49). CONCLUSION Relationship factors, including shorter-term, unmarried, and polygamous relationships and uncertainty about partner's HIV testing history, were associated with higher likelihood of pregnant women's nondisclosure of HIV status to their partner. Interventions that facilitate couples' HIV testing and disclosure, provide counseling to reduce relationship dissolution in serodiscordant couples, and offer peer support for women may increase disclosure.

Long-term virological outcomes in women who started option B+ care during pregnancy for prevention of mother-to-child transmission of HIV in Dar es Salaam, Tanzania: a cohort study. Lancet HIV 2021; 8:e256-e265. [PMID: 33581776 DOI: 10.1016/s2352-3018(20)30308-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2020] [Revised: 10/20/2020] [Accepted: 11/09/2020] [Indexed: 01/25/2023]
Abstract
BACKGROUND Option B+ marked a milestone in prevention of mother-to-child transmission (PMTCT) of HIV by recommending lifelong antiretroviral therapy (ART) for all pregnant women with HIV. Nevertheless, concerns remain regarding long-term outcomes in settings with a high HIV burden. We analysed long-term virological outcomes in women enrolled on option B+ in Tanzania. METHODS In this prospective cohort study, we extracted data for pregnant women with HIV starting PMTCT care between Oct 1, 2014, and Sept 30, 2016, in routine health-care settings in Dar es Salaam, Tanzania, from national HIV and district health information system databases. We then excluded women who exited study sites before 6 months of ART follow-up and women who did not have a viral load test. Women were followed up until March 8, 2019. We used Poisson generalised estimating equations to examine trends in HIV viral suppression (<400 copies per mL) and virological failure (≥400 copies per mL), reporting relative risks (RRs) and 95% CIs adjusted for maternal age, gestational age, and several clinical characteristics. FINDINGS We identified 15 586 pregnant women with HIV, of whom 10 161 were eligible for follow-up. Women were followed up for a median of 37 months (IQR 31-45) and a maximum of 53 months. The median age at PMTCT initiation was 31 years (IQR 27-35). At PMTCT enrolment, 1245 (17·0%) of 7318 women with available data were in their third trimester, 4901 (48·2%) of 10 161 women started ART at least 1 month before PMTCT enrolment, and 3380 (33·4%) of 10 131 women with available data had advanced HIV. Overall, a viral suppression rate of 88·2% (95% CI 87·8-88·7) was observed over the entire follow-up period, ranging from 85·1% (84·3-85·9) in viral load tests done at 0-11 months to 90·6% (89·7-91·4) at 36 months or longer since PMTCT enrolment. In a complete-case analysis (ie, including patients with <30% missing data; n=7306), the risk of virological failure among women who remained in HIV care decreased over time (adjusted RR 0·87 [95% CI 0·80-0·95] at 12-23 months since PMTCT enrolment; 0·65 [0·59-0·72] at 24-35 months; and 0·63 [0·55-0·71] at ≥36 months vs at 0-11 months). Younger women (aged <20 years: 1·76 [1·40-2·23] vs aged 30-39 years) and those starting PMTCT late in pregnancy (third trimester: 1·28 [1·10-1·50] vs first trimester) or with advanced HIV (1·33 [1·16-1·51] vs without advanced HIV) had increased risk of virological failure. Women who attended an antenatal care facility where more than 50% of attendees received couples HIV testing had a decreased risk of virological failure (adjusted RR 0·81 [0·65-0·99] vs <50% having couples testing). INTERPRETATION High rates of viral suppression among women starting option B+ who remain in HIV care are sustainable, and might increase, at least up to 53 months. This rate might be further improved by addressing challenges of adolescent mothers, late presenters, and couples HIV testing at antenatal care. FUNDING Swedish International Development Agency.

The magnitude of adherence to option B plus program and associated factors among women in eastern African countries: a systematic review and meta-analysis. BMC Public Health 2020; 20:1812. [PMID: 33246437 PMCID: PMC7693523 DOI: 10.1186/s12889-020-09903-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Accepted: 11/17/2020] [Indexed: 11/29/2022] Open
Abstract
Background Despite coverage and benefits associated with the prevention of mothers to child transmission (PMTCT) services, mothers’ adherence to option B plus is still a challenge. Though few primary studies are available on the magnitude of adherence to option B plus and factors associated in Eastern African countries, they do not provide strong evidence in helping policymakers to address suboptimal adherence to option B plus. Therefore, this systematic review and meta-analysis was intended to estimate the pooled magnitude of adherence to option B plus program and associated factors among women in Eastern African countries. Methods PubMed, Medline, HINARI, Cochrane library, the Web of Science, and Google Scholar were searched for studies reported on the magnitude of adherence to option B plus among women in Eastern African countries. The search terms used were “option B plus”, “magnitude”, “prevalence”, “PMTCT”, “ART adherence”, “associated factors”, “all lists of Eastern African countries” and their combination by Boolean operators. The effect sizes of the meta-analysis were the magnitude of adherence to option B plus and the odds ratio of the associated factors. STATA/SE V14 was used for statistical analysis, and publication bias was assessed using funnel plots and Egger’s test. Results Fourteen studies having total participants of 4883 were included in the systematic review and meta-analysis. Using the random effect model, the pooled prevalence of adherence to option B plus was 71.88% (95% CI: 58.54–85.23%). The factors associated with good adherence to option B plus PMTCT program were partner support (Adjusted odds ratio (AOR) = 4.13; 95% CI: 2.78–6.15), received counseling services (AOR = 4.12, 95% CI: 2.81–6.02), disclosure of HIV status to partner (AOR = 4.38; 95% CI: 1.79–10.70), and clinical stage of HIV/AIDS I/II (AOR = 2.62; 95% CI: 1.53–4.46). Conclusion The level of adherence to option B plus program in Eastern African countries was generally sub-optimal. Thus, a coordinated effort is needed to raise the number of mothers to be tested, and early treatment initiation for HIV positive mothers before the disease advances. Furthermore, counseling services for couples on the importance of early treatment initiation and adherence to medications must be given due attention.

Abstract
The aim of the study was to investigate the relationship between counseling prior to starting antiretroviral treatment (ART) and adherence to treatment among women enrolled in Option B+ in Zambia. Using convenience sampling, 150 HIV+ women enrolled in an Option B+ treatment regimen in rural and urban districts were recruited. Four generalized Poisson regression models were built to assess the association between counseling and adherence to ART. In all, 75% of the participants reported adherence in the past 7 days. In adjusted analyses, there was a significant positive relationship between counseling and adherence in the rural district (prevalence ratio [PR] 2.52, 95% CI [1.19, 5.35], n = 81) but not in the urban district (PR = 0.77, 95% CI [0.15, 3.91], n = 69). Offering counseling prior to initiating antiretroviral treatment to HIV+ women is particularly important for promoting medication adherence in rural settings of low resourced countries.

Abstract
PURPOSE A major global public health challenge is the continuance of new pediatric HIV infections primarily because of mother to child transmission of HIV occurring mainly in sub-Saharan African countries. The purpose of this study was to examine antiretroviral therapy (ART) refill adherence and its determinants among pregnant women living with HIV in Nigeria. METHODS A retrospective review of pharmacy refill records was undertaken to examine adherence data on 275 pregnant women undergoing ART in 4 high-volume HIV treatment sites in Nigeria. A pharmacy refill adherence measure was used to assess medication refill behavior of pregnant women living with HIV who had received an ART refill during a period of 3 months. Medication-based ART refill adherence was categorized as % adherence (100% adherence) or % nonadherence (<100% adherence) to the ART refill scheduled dates. Refill appointments were scheduled on a 28-day cycle. Multivariable logistic regression analysis was performed. FINDINGS Of the 275 women, 59.3% (95% CI, 53.1%-65.5%) were adherent to their ART refill schedule. Women who initiated ART during the third trimester of their current pregnancy had the lowest adherence rate of 30.8% (95% CI, 7.7%-53.8%) compared with women who commenced ART before conception or during the first or second trimester. The availability of a treatment support person was significantly associated with ART refill adherence. The odds of medication-based refill adherence were 2.9 times higher for participants who had a treatment support person (odds ratio = 2.9; 95% CI, 1.6-5.2; p = 0.001). IMPLICATIONS Results indicate that having a treatment support person could contribute to improving ART adherence in pregnant women living in Nigeria.

Abstract
PURPOSE OF REVIEW HIV remains a significant global public health problem. Treatment as prevention of HIV and TB illness, death and transmission was proposed in 2006 as a means to end the HIV epidemic. We review the results of the treatment as prevention trials. RECENT FINDINGS Some of the trials struggled with delivering services, however, most demonstrate that it is feasible to achieve at least the 90-90-90 target by scaling access to test-and-treat at the community level and by extension at the district or national level. Patients, if offered, will start and stay on immediate treatment even without symptoms. Community-based multidisease prevention campaigns have significant impact, especially for hard-to-reach men. Earlier treatment impacts illness and death including from HIV-associated tuberculosis. Test-and treat impacts transmission, however, some of the community cluster trials had difficulty showing an impact on incidence. Most trials showed incidence reduction in line with the level of viral suppression and suggest that achieving 95-95-95 is an important means to accelerate the end of the epidemic. SUMMARY TasP trial findings, HIV and TB program data, and PHIA study trend data will likely confirm that reaching at least 95-95-95 is both feasible and a key element in ending the epidemic.

OBJECTIVES To assess the validity of self-reported HIV status, and investigate factors that influence accurate reporting of HIV-positive status, in a population tested and informed of their HIV test result. DESIGN Prospective cohort study. METHODS We compared self-reported HIV status with biomarker-confirmed HIV test status among participants of Karonga Health and Demographic Surveillance Site in rural northern Malawi. We linked information on HIV test results to subsequent self-reported HIV status, and calculated sensitivity, specificity, positive predictive value and negative predictive value for self-reported HIV status (considered as a diagnostic test). We used Poisson regression with robust variance estimators to examine predictors of accurate self-reporting of HIV-positive status. RESULTS Among 17 445 adults who tested for HIV, were recorded as having received their HIV test results, and had a subsequent self-reported HIV status between 2007 and 2018: positive predictive value of self-reported HIV status was 98.0% (95% confidence interval: 97.3-98.7); negative predictive value was 98.3 (98.1-98.5); sensitivity was 86.1% (84.5-87.7); and specificity was 99.8% (99.7-99.9). Among true HIV-positive people, those who were younger, interviewed in community settings, and had tested for HIV longer ago were more likely to misreport their HIV-positive status. CONCLUSION In this setting, self-report provides good estimates of test-detected HIV prevalence, suggesting that it can be used when HIV test results are not available. Despite frequent HIV testing, younger people and those interviewed in community settings were less likely to accurately report their HIV-positive status. More research on barriers to self-reporting of HIV status is needed in these subgroups.

Abstract
BACKGROUND The World Health Organization recommends antiretroviral therapy (ART) for all HIV-infected patients at all CD4 counts. However, there are concerns that asymptomatic patients may have poorer viral suppression and high attrition. OBJECTIVES We sought to determine attrition and viral suppression among healthy HIV-infected patients initiated on ART in program settings. METHODS This cross-sectional study enrolled ART-experienced patients attending two PEPFAR-supported, high-volume clinics in Kampala, Uganda. Eligible patients were >18 years and had completed at least six months on ART. Participants were interviewed on socio-demographics, ART history and plasma viral load (VL) determined using Abbott Real-time. Predictors of viral suppression (<75 copies/ml) were determined using multivariate logistic regression. RESULTS Overall, 267 participants were screened, 228 were eligible and 203 (89%) retained in care (visit within 90 days). Of the 203 participants, 115 (56.7%) were key-populations. Viral suppression was achieved in 173 patients (85%; 95% CI, 80.3%-90.1%). The factors associated with viral suppression were prior VL tests (AOR 6.98; p-value <0.001) and receiving care from a general clinic (AOR 5.41; p=0.009). CONCLUSION Asymptomatic patients initiated on ART with high baseline CD4 counts, achieve high viral suppression with low risk of attrition. VL monitoring and clinic type are associated with viral suppression.

Abstract
The PROMISE trial enrolled asymptomatic HIV-infected pregnant and postpartum women not eligible for antiretroviral treatment (ART) per local guidelines and randomly assigned proven antiretroviral strategies to assess relative efficacy for perinatal prevention plus maternal/infant safety and maternal health. The START study subsequently demonstrated clear benefit in initiating ART regardless of CD4 count. Active PROMISE participants were informed of results and women not receiving ART were strongly recommended to immediately initiate treatment to optimize their own health. We recorded their decision and the primary reason given for accepting or rejecting the universal ART offer after receiving the START information. One-third of participants did not initiate ART after the initial session, wanting more time to consider. Six sessions were required to attain 95% uptake. The slow uptake of universal ART highlights the need to prepare individuals and sensitize communities regarding the personal and population benefits of the "Treat All" strategy.

Abstract
Background Despite an increased uptake of option B+ treatment among HIV- positive pregnant and breastfeeding women, retaining these women in care is still a major challenge. Previous studies have identified factors associated with loss to follow-up (LTFU) in HIV care, however, the perspectives from HIV-positive pregnant and breastfeeding women regarding their LTFU in option B+ needs further exploration. We explored reasons for LTFU and motivation to resume treatment among HIV-positive women initiated in option B+ in an Urban setting. Methods A descriptive qualitative study was conducted at three public care and treatment clinics (CTC) (Buguruni health center, Sinza hospital, and Mbagala Rangitatu health center) in Dar es Salaam, Tanzania between February and May 2017. In-depth interviews were conducted with 30 HIV-positive pregnant and breastfeeding women who were lost to follow up in the option B+ regimen. Analysis of data followed content analysis that was performed using NVivo 10 computer-assisted qualitative data analysis software. Results Eleven women were lost to follow-up and did not resume Option B+, while 19 had resumed treatment. The study indicated a struggle with long term disease amongst HIV-positive pregnant and breastfeeding women initiated in option B+ treatment. The reported reasons contributing to LTFU among these women appeared in three categories. The contribution of LTFU in the first category namely health-related factors included medication side effects and lack of disease symptoms. The second category highlighted the contribution of psychological factors such as loss of hope, fear of medication side effects and HIV-related stigma. The third category underscored the influence of socio-economic statuses such as financial constraints, lack of partner support, family conflicts, non-disclosure of HIV-positive status, and religious beliefs. Motivators to resume treatment after LTFU included support from health care providers and family members, a desire to protect the unborn child from HIV-infection and a need to maintain a healthy status. Conclusion The study has highlighted the reasons for LTFU and motivation to resume treatment among women initiated in Option B+. Our results provide further evidence on the need for future interventions to focus on these factors in order to improve retention in life-long treatment.

Abstract
Background Prevention of mother-to-child transmission (PMTCT) across sub-Saharan Africa has rapidly shifted towards Option B+, an approach in which all HIV+ pregnant and breastfeeding women initiate lifelong antiretroviral therapy (ART) independent of CD4+ count. Healthcare workers (HCW) are critical to the success of Option B+, yet little is known regarding HCW acceptability of Option B+, particularly over time. Methods Ten health facilities in the Manzini and Lubombo regions of eSwatini transitioned from Option A to Option B+ between 2013 and 2014 as part of the Safe Generations study examining PMTCT retention. Fifty HCWs (5 per facility) completed questionnaires assessing feasibility and acceptability: (1) prior to transitioning to Option B+, (2) two months post transition, and (3) approximately 2 years post Option B+ transition. This analysis describes HCW perceptions and experiences two years after transitioning to Option B+. Results Two years after transition, 80% of HCWs surveyed reported that Option B+ was easy for HCWs, noting that it was particularly easy to explain and coordinate. Immediate ART initiation also reduced delays by eliminating need for laboratory tests prior to ART initiation. Additionally, HCWs reported ease of patient follow-up (58%), documentation (56%), and counseling (58%) under Option B+. Findings also indicate that a majority of HCWs reported that their workloads increased under Option B+. Sixty-eight percent of HCWs at two years post-transition reported more work under Option B+, specifically noting increased involvement in adherence counseling, prescribing/monitoring medications, and appointment scheduling/tracking. Some HCWs attributed their higher workloads to increased client loads, now that all HIV-positive women were initiated on ART. New barriers to patient uptake, and issues related to retention, adherence, and follow-up were also noted as challenges face by HCW when implementing Option B+. Conclusions Overall, HCWs found Option B+ to be acceptable and feasible while providing critical insights into the practical issues of universal ART. Further strengthening of the healthcare system may be necessary to alleviate worker burden and to ensure effective monitoring of client retention and adherence. HCW perceptions and experiences with Option B+ should be considered more broadly as countries implement Option B+ and consider universal treatment for all HIV+ individuals.

Abstract
BACKGROUND Under Option B+ guidelines for prevention of mother-to-child transmission of HIV, pregnant and breastfeeding women initiate antiretroviral therapy for lifelong use. The objectives of this study were: (1) to synthesize data on retention in care over time in option B+ programs in Africa, and (2) to identify factors associated with retention in care. METHODS PubMed, EMBASE, and African Index Medicus were systematically searched from January 2012 to June 2017. Pooled estimates of the proportion of women retained were generated and factors associated with retention were analyzed thematically. RESULTS Thirty-five articles were included in the final review; 22 reported retention rates (n = 60,890) and 25 reported factors associated with retention. Pooled estimates of retention were 72.9% (95% confidence interval: 66.4% to 78.9%) at 6 months for studies reporting <12 months of follow-up and 76.4% (95% confidence interval: 69.0% to 83.1%) at 12 months for studies reporting ≥12 months of follow-up. Data on undocumented clinic transfers were largely absent. Risk factors for poor retention included younger age, initiating antiretroviral therapy on the same day as diagnosis, initiating during pregnancy versus breastfeeding, and initiating late in the pregnancy. Retention was compromised by stigma, fear of disclosure, and lack of social support. CONCLUSIONS Retention rates in prevention of mother-to-child transmission under option B+ were below those of the general adult population, necessitating interventions targeting the complex circumstances of women initiating care under option B+. Improved and standardized procedures to track and report retention are needed to accurately represent care engagement and capture undocumented transfers within the health system.

Abstract
Utilization of the prevention of mother-to-child transmission of HIV (PMTCT) services remains a challenge as losses to follow-up are substantial. This study explored factors that influence adherence to maternal antiretroviral (ARV) medications among PMTCT mothers in Malawi. We conducted a descriptive qualitative study from September 2016 to May 2017 using purposive sampling among 16 PMTCT mothers and 4 key informant interviews with health-care workers. Data were audio-recorded and analyzed thematically. The factors that influence adherence to maternal ARV medications include the quality of PMTCT services and social support. Factors that impede adherence include suboptimal counseling women receive on ARV medications, cost of travel, and conflicting advice from religious institutions. Adherence to maternal ARV medications will require the use of existing social support systems in a woman's life as a platform for delivery of the drugs while also maintaining continued and comprehensive counseling on the benefits of maternal ARV medications.

Abstract
The acceptability of lifelong antiretroviral therapy (ART) among HIV-positive women in high-burden Nigeria, is not well-known. We explored readiness of users and providers of prevention of mother-to-child transmission of HIV (PMTCT) services to accept lifelong ART -before Option B plus was implemented in Nigeria. We conducted 142 key informant interviews among 100 PMTCT users (25 pregnant-newly-diagnosed, 26 pregnant-in-care, 28 lost-to-follow-up (LTFU) and 21 postpartum women living with HIV) and 42 PMTCT providers in rural North-Central Nigeria. Qualitative data were manually analyzed via Grounded Theory. PMTCT users had mixed views about lifelong ART, strongly influenced by motivation to prevent infant HIV and by presence or absence of maternal illness. Newly-diagnosed women were most enthusiastic about lifelong ART, however postpartum and LTFU women expressed conditionalities for acceptance and adherence, including minimal ART side effects and potentially serious maternal illness. Providers corroborated user findings, identifying the postpartum period as problematic for lifelong ART acceptability/adherence. Option B plus scale-up in Nigeria will require proactively addressing PMTCT user fears about ART side effects, and continuous education on long-term maternal and infant benefits. Structural barriers such as the availability of trained providers, long clinic wait times and patient access to ART should also be addressed.

Abstract
BACKGROUND Routine data from Malawi's prevention of mother-to-child transmission (MTCT) option B+ programme suggest high uptake of antiretroviral therapy (ART) among pregnant women. Malawi's Ministry of Health led the National Evaluation of Malawi's PMTCT Program to obtain nationally representative data on maternal ART coverage and prevention of MTCT effectiveness. Here, we present the early transmission data for infants aged 4-12 weeks. METHODS We used a multistage cluster design to recruit a nationally representative sample of HIV-exposed infants and their mothers in Malawi. Between October 16, 2014, and May 17, 2016, we screened for HIV in all mothers attending an under-5 vaccination or outpatient sick-child clinic with infants aged 4-26 weeks at 54 health facilities selected across ten districts and four regional sampling zones. Infants with mothers identified as HIV-infected were enrolled in the cohort. We calculated weighted MTCT rates for only the subset of infants aged 4-12 weeks at screening, thereby capturing MTCT from early pregnancy, to delivery, and early breastfeeding. We collected data on maternal and infant demographics and self-reported use of HIV services, ART, and antenatal clinics. We tested HIV-exposed infants for the virus and assessed associations of certain variables with infant HIV status. FINDINGS We confirmed HIV exposure in 3542 (10·4%) of 33 980 mother (guardian)-infant pairs with infants aged 4-26 weeks. Of those, 2530 (2514 mothers and 16 guardians) had infants aged 4-12 weeks at the time of screening (2498 singlets and 32 twins). We excluded 25 infants from the analysis because no information was available about their HIV status. 91·3% (95% CI 85·6-96·9) of mothers were on ART during pregnancy. The MTCT rate was 3·7% (2·3-6·0) overall and ranged from 1·4% (0·4-4·4) in women who initiated ART before pregnancy to 19·9% (13·4-28·6) in women not on ART. In multivariable logistic regression analysis, the odds of early MTCT were higher in mothers starting ART post partum (adjusted odds ratio 16·7, 95% CI 1·6-171·5; p=0·022) and in those not on ART with an unknown HIV status during pregnancy (19·1, 8·5-43·0; p<0·0001) than in mothers on ART before pregnancy. Among HIV-exposed infants, 98·0% (95% CI 96·9-99·1) were reported by the mother to have received infant nevirapine prophylaxis, and only 45·6% (34·8-56·4) were already enrolled in an exposed infant HIV care clinic at the time of study screening. INTERPRETATION These data suggest that Malawi's decentralisation of ART services has resulted in higher ART coverage and lower early MTCT. However, the uptake of services for HIV-exposed infants remains suboptimal. FUNDING President's Emergency Plan for AIDS Relief.

Abstract
HIV-infected pregnant women face complex decisions about whether and how to disclose their serostatus. Previous studies have shown that HIV disclosure is associated with better care engagement, emotional adjustment to the disease, and reduced risk of HIV transmission, but women face both real and perceived barriers to disclosure. We examined patterns and predictors of HIV disclosure in a cohort of 200 women diagnosed or confirmed to have HIV during antenatal care in the Kilimanjaro region of Tanzania and followed participants to three months postpartum. Twenty women also completed qualitative in-depth interviews during pregnancy and three months postpartum. During the pregnancy period (at least 30 days post-diagnosis), 79.5% of women had disclosed to at least one other person, with disclosures generally restricted to the father of the child and/or a small number of close family members. By three months postpartum, 11.9% of women had still not disclosed to anyone. Women who presented to antenatal care with an established HIV diagnoses and married women were more likely to report disclosures. Social support was positively associated with disclosure. In qualitative interviews, women pointed to community gossip and stigma as barriers to disclosure. Those who had not disclosed to the father of the child noted fears of abandonment during the vulnerable pregnancy period. Despite expressed fears, participants reported overall positive experiences of disclosure that led to increased support. Taken together, these results point to the need for comprehensive, flexible, and culturally informed interventions that assist pregnant and postpartum women in deciding when and how to disclose. Such interventions should acknowledge and explore common barriers to disclosure, including fears of public stigma and personal consequences. Given the strong associations between disclosure, social support, and community stigma, interventions for disclosure should be nested in broader efforts of public education and HIV stigma reduction.

Abstract
BACKGROUND Between 2011 and 2013, global and national guidelines for preventing mother-to-child transmission (PMTCT) of HIV shifted to recommend Option B+, the provision of lifelong antiretroviral treatment for all HIV-infected pregnant women. METHODS We aimed to analyse how Option B+ reached the policy agenda, and unpack the processes, actors and politics that explain its adoption, with a focus on examining UNICEF's contribution to these events. Analysis drew on published articles and other documentation, 30 key informants interviews with staff at UNICEF, partner organisations and government officials, and country case studies. Cameroon, India, South Africa and Zimbabwe were each visited for 5-8 days. Interview transcripts were analysed using Dedoose software, reviewed several times and then coded thematically. RESULTS A national policy initiative in Malawi in 2011, in which the country adopted Option B+, rather than existing WHO recommended regimens, irrevocably placed the policy on the global agenda. UNICEF and other organisations recognised the policy's potential impact and strategically crafted arguments to support it, framing these around operational considerations, cost-effectiveness and values. As 'policy entrepreneurs', these organisations vigorously promoted the policy through a variety of channels and means, overcoming concerted opposition. WHO, on the basis of scanty evidence, released a series of documents towards the policy's endorsement, paving the way for its widespread adoption. National-level policy transformation was rapid and definitive, distinct from previous incremental policy processes. Many organisations, including UNICEF, facilitated these changes in country, acting individually, or in concert. CONCLUSIONS The adoption of the Option B+ policy marked a departure from established processes for PMTCT policy formulation which had been led by WHO with the support of technical experts, and in which recommendations were developed following shifts in evidence. Rather, changes were spurred by a country-level initiative, and a set of strategically framed arguments that resonated with funders and country-level actors. This bottom-up approach, supported by normative agencies, was transformative. For UNICEF, alignment between the organisation's country focus and the policy's underpinning values, enabled it to work with partners and accelerate widespread policy change.

Abstract
BACKGROUND Malawi, Uganda, and Zimbabwe have recently adopted a universal 'test-and-treat' approach to the prevention of mother-to-child transmission of HIV (Option B+). Amongst a largely asymptomatic population of women tested for HIV and immediately started on antiretroviral treatment (ART), a relatively high number are not retained in care; they are labelled 'defaulters' or 'lost-to-follow-up' patients. METHODS We draw on data collected as part of a study looking at ART decentralization (Lablite) to reflect on the spaces created through the instrumentalization of community health workers (CHWs) for the purpose of bringing women who default from Option B+ back into care. Data were collected through semi-structured interviews with CHWs who are designated to trace Option B+ patients in Uganda, Malawi and Zimbabwe. FINDINGS Lost to follow up women give a range of reasons for not coming back to health facilities and often implicitly choose not to be traced by providing a false address at enrolment. New strategies have sought to utilize CHWs' liminal positionality - situated between the experience of living with HIV, having established local social ties, and being a caretaker - in order to track 'defaulters'. CHWs are often deployed without adequate guidance or training to protect confidentiality and respect patients' choice. CONCLUSIONS CHWs provide essential linkages between health services and patients; they embody the role of 'extension workers', a bridge between a novel health policy and 'non-compliant patients'. Option B+ offers a powerful narrative of the construction of a unilateral 'moral economy', which requires the full compliance of patients newly initiated on treatment.

Abstract
In 2012, the World Health Organization recommended 'Option B+' (lifelong antiretroviral treatment for HIV-infected pregnant women regardless of their CD4 count or WHO clinical stage) for prevention of mother-to-child transmission of HIV-based on its operational and clinical advantages. By 2015, 21 out of the 22 Global Plan priority countries had adopted the Option B+ approach. Despite its huge HIV burden, Nigeria is the only country yet to adopt Option B+. We analyse the policymaking process on Option B+ in Nigeria from 2012-2015, highlighting how factors related to the content (uncertainty about Option B+, lack of local evidence), actors (interest and power) and context (low domestic funding and poor retention in care) affected the policymaking process and present the implications of this decision for improving HIV response in Nigeria.

Abstract
Introduction: Policies for rationing antiretroviral therapy (ART) have been subject to on-going ethical debates. Introduced in Malawi in 2011, Option B+ prioritized HIV-positive pregnant women for lifelong ART regardless of the underlying state of their immune system, shifting the logic of allocation away from medical eligibility. Despite the rapid expansion of this policy, we know little about how it has been understood and interpreted by the people it affects. Methods: We assessed awareness and perceived fairness of the prioritization system for ART among a population-based sample of young women (n = 1440) and their partners (n = 574) in southern Malawi. We use a card-sort technique to elicit understandings of who gets ART under Option B+ and who should be prioritized, and we compare perceptions to actual ART policy using sequence analysis and optimal matching. We then use ordered logistic regression to identify the factors associated with policy awareness. Results: In 2015, only 30.7% of women and 21.1% of male partners understood how ART was being distributed. There was widespread confusion around whether otherwise healthy HIV-positive pregnant women could access ART under Option B + . Nonetheless, more young adults thought that the fairest policy should prioritize such women than believed the actual policy did. Women who were older, more educated or had recently engaged with the health system through antenatal care or ART had more accurate understandings of Option B + . Among men, policy awareness was lower, and was patterned only by education. Conclusions: Although most respondents were unaware that Option B+ afforded ART access to healthy-pregnant women, Malawians support the prioritization of pregnant women. Countries adopting Option B+ or other new ART policies such as universal test-and-treat should communicate the policies and their rationales to the public – such transparency would be more consistent with a fair and ethical process and could additionally serve to clarify confusion and enhance retention.

Abstract
BACKGROUND Several studies from sub-Saharan Africa have highlighted significant challenges in providing antiretroviral therapy (ART) to pregnant and postpartum women, with specific concerns around maintaining optimal levels of adherence to ART and/or retaining women in long-term services. However, there are few conceptual frameworks to help understand nonadherence and nonretention, as well as the drivers of these, among HIV-infected women, particularly in the postpartum period. METHODS This review provides an overview of the key issues involved in thinking about ART adherence, retention in care and engagement in ART services among pregnant and postpartum women. RESULTS The related behaviors of adherence and retention may be understood as components of effective engagement of patients in ART services, which share the goal of achieving and maintaining suppressed maternal viral load on ART. Under this framework, the existing literature indicates that disengagement from care is widespread among postpartum women, with strikingly similar data emerging from ART services around the globe and indications that similar challenges may be encountered by postpartum care services outside the context of HIV. However, the drivers of disengagement require further research, and evidence-based intervention strategies are limited. CONCLUSIONS The challenges of engaging women in ART services during pregnancy and the postpartum period seem pervasive, although the determinants of these are poorly understood. Looking forward, a host of innovative intervention approaches are needed to help improve women's engagement, and in turn, promote maternal and child health in the context of HIV.

Abstract
Background In October 2012 Uganda extended its prevention of mother to child HIV transmission (PMTCT) policy to Option B+, providing lifelong antiretroviral treatment for HIV positive pregnant and breastfeeding women. The rapid changes and adoptions of new PMTCT policies have not been accompanied by health systems research to explore health system preparedness to implement such programmes. The implementation of Option B+ provides many lessons which can inform the shift to ‘Universal Test and Treat’, a policy which many sub-Saharan African countries are preparing to adopt, despite fragile health systems. Methods This qualitative study of PMTCT Option B+ implementation in Uganda three years following the policy adoption, uses the health system dynamics framework to explore the impacts of this programme on ten elements of the health system. Qualitative data were gathered through rapid appraisal during in-country field work. Key informant interviews and focus group discussions (FGDs) were undertaken with the Ministry of Health, implementing partners, multilateral agencies, district management teams, facility-based health workers and community cadres. A total of 82 individual interviews and 16 focus group discussions were completed. We conducted a simple manifest analysis, using the ten elements of a health system for grouping data into categories and themes. Results Of the ten elements in the health system dynamics framework, context and resources (finances, infrastructure & supplies, and human resources) were the most influential in the implementation of Option B+ in Uganda. Support from international actors and implementing partners attempted to strengthen resources at district level, but had unintended consequences of creating dependence and uncertainty regarding sustainability. Conclusions The health system dynamics framework offers a novel approach to analysis of the effects of implementation of a new policy on critical elements of the health system. Its emphasis on relationships between system elements, population and context is helpful in unpacking impacts of and reactions to pressures on the system, which adds value beyond some previous frameworks.

Abstract
Background In 2013, the World Health Organization released a new set of guidelines widely known as Option B+. Prior to that there were guidelines released in 2010. Option B+ recommends lifelong antiretroviral treatment for all pregnant and breastfeeding women living with Human Immunodeficiency Virus. The study aimed at investigating challenges and opportunities in implementing Infant and Young Child Feeding in the context of Prevention of Mother To Child Transmission (PMTCT) guidelines among HIV positive mothers of children aged 0–24 months. The study also examined implications presented by implementing the 2013 PMTCT consolidated guidelines in the transition phase from the 2010 approach in Zambia. Methods A mixed methods approach was employed in the descriptive cross sectional study utilizing semi structured questionnaires and Focused Group Discussions. Further, data was captured from the Health Information Management System. Results During the PMTCT transition, associated needs and challenges in institutionalizing the enhanced guidelines from option A and B to option B+ were observed. Nonetheless, there was a decline in Mother to Child Transmission (MTCT) of HIV rates with an average of 4%. Mothers faced challenges in complying with optimal breastfeeding practices owing to lack of community support systems and breast infections due to poor breast feeding occasioned by infants’ oral health challenges. Moreover, some mothers were hesitant of lifelong ARVs. Health workers faced programmatic and operational challenges such as compromised counseling services. Conclusion Despite the ambitious timelines for PMTCT transition, the need to inculcate new knowledge and vary known practice among mothers and the shift in counseling content for health workers, the consolidated guidelines for PMTCT proved effective. Some mothers were hesitant of lifelong ARVs, rationalizing the debated paradigm that prolonged chemotherapy/polypharmacy may be a future challenge in the success of ART in PMTCT. Conflicting breast feeding practices was a common observation across mothers thus underpinning the need to strongly invigorate Infant and Young Child Feeding information sharing across the continuum of heath care from facility level to community and up to the family; for cultural norms, practices and attitudes enshrined within communities play a vital role in child care.

Abstract
Background Health benefits of postpartum antiretroviral therapy (ART) for human immunodeficiency virus (HIV) positive women with high CD4+ T-counts have not been assessed in randomized trials. Methods Asymptomatic, HIV-positive, non-breastfeeding women with pre-ART CD4+ T-cell counts ≥ 400 cells/mm3 started on ART during pregnancy were randomized up to 42 days after delivery to continue or discontinue ART. Lopinavir/ritonavir plus tenofovir/emtricitabine was the preferred ART regimen. The sample size was selected to provide 88% power to detect a 50% reduction from an annualized primary event rate of 2.07%. A post-hoc analysis evaluated HIV/AIDS-related and World Health Organization (WHO) Stage 2 and 3 events. All analyses were intent to treat. Results 1652 women from 52 sites in Argentina, Botswana, Brazil, China, Haiti, Peru, Thailand and the US were enrolled (1/2010-11/2014). Median age was 28 years and major racial categories were Black African (28%), Asian (25%) White (15%). Median entry CD4 count was 696 cells/mm3 (IQR 575–869), median ART exposure prior to delivery was 19 weeks (IQR 13–24) and 94% had entry HIV-1 RNA < 1000 copies/ml. After a median follow-up of 2.3 years, the primary composite endpoint rate was significantly lower than expected, and not significantly different between arms (continue arm 0.21 /100 person years(py); discontinue 0.31/100 py, Hazard ratio (HR) 0.68, 95% CI: 0.19, 2.40). WHO Stage 2 and 3 events were significantly reduced with continued ART (2.08/100 py vs. 4.36/100 py in the discontinue arm; HR 0.48, 95%CI: 0.33, 0.70). Toxicity rates did not differ significantly between arms. Among women randomized to continue ART, 189/827 (23%) had virologic failure; of the 155 with resistance testing, 103 (66%) failed without resistance to their current regimen, suggesting non-adherence. Conclusions Overall, serious clinical events were rare among young HIV-positive post-partum women with high CD4 cell counts. Continued ART was safe and was associated with a halving of the rate of WHO 2/3 conditions. Virologic failure rates were high, underscoring the urgent need to improve adherence in this population.

Abstract
BACKGROUND Option B+ is promoted as a key component to eliminating vertical transmission of HIV; however, little is known about the policy's impact on non-targeted populations, such as men and non-pregnant/non-breastfeeding women. We compare ART uptake among non-targeted populations during pre/post Option B+ periods in Zomba District, Malawi. METHODS Individual-level ART registry data from 27 health facilities were digitized and new ART initiates were disaggregated by sex and type of initiate (Option B+ or not). Data were analyzed over the pre- (January 2009-June 2011) and post- (July 2011- December 2013) Option B+ periods. RESULTS After the implementation of Option B+, the total number of new female initiates increased significantly (quarterly median: 547 vs. 816; P = 0.001) and their median age decreased from 34 to 31 years (P = <0.001). Both changes were the result of the rapid and sustained uptake of ART among Option B+ clients. Post-policy, Option B+ clients represented 48% of all new female initiates while the number of females who initiated through CD4 or WHO staging criteria significantly decreased (quarterly median: 547 vs. 419; P = 0.005). The number and age of male initiates remained stable; however, the proportion of men among new initiates decreased (36% vs. 31%; P = <0.001). CONCLUSIONS Option B+ shifted the profile of first-time initiates towards younger and fertile women. Declines among non-Option B+ women most likely reflect earlier initiation during pregnancies before deteriorations in health. The decreased proportion of men among first-time initiates represents a growing gender disparity in HIV services that deserves immediate attention.

Abstract
One-third of women enrolled in Malawi's program to prevent human immunodeficiency virus mother-to-child-transmission (Option B+) adhered inadequately to antiretroviral therapy during pregnancy and breastfeeding. Long-term virological outcomes must be closely monitored, and effective interventions to improve adherence should be deployed. Background. Adherence to antiretroviral therapy (ART) is crucial to preventing mother-to-child transmission of human immunodeficiency virus (HIV) and ensuring the long-term effectiveness of ART, yet data are sparse from African routine care programs on maternal adherence to triple ART. Methods. We analyzed data from women who started ART at 13 large health facilities in Malawi between September 2011 and October 2013. We defined adherence as the percentage of days “covered” by pharmacy claims. Adherence of ≥90% was deemed adequate. We calculated inverse probability of censoring weights to adjust adherence estimates for informative censoring. We used descriptive statistics, survival analysis, and pooled logistic regression to compare adherence between pregnant and breastfeeding women eligible for ART under Option B+, and nonpregnant and nonbreastfeeding women who started ART with low CD4 cell counts or World Health Organization clinical stage 3/4 disease. Results. Adherence was adequate for 73% of the women during pregnancy, for 66% in the first 3 months post partum, and for about 75% during months 4–21 post partum. About 70% of women who started ART during pregnancy and breastfeeding adhered adequately during the first 2 years of ART, but only about 30% of them had maintained adequate adherence at every visit. Risk factors for inadequate adherence included starting ART with an Option B+ indication, at a younger age, or at a district hospital or health center. Conclusions. One-third of women retained in the Option B+ program adhered inadequately during pregnancy and breastfeeding, especially soon after delivery. Effective interventions to improve adherence among women in this program should be implemented.

Reassuring Birth Outcomes With Tenofovir/Emtricitabine/Efavirenz Used for Prevention of Mother-to-Child Transmission of HIV in Botswana. J Acquir Immune Defic Syndr 2016; 71:428-36.

Abstract
BACKGROUND Before introduction of tenofovir/emtricitabine/efavirenz (TDF/FTC/EFV), 3-drug antiretroviral therapy (ART) was associated with increased adverse birth outcomes when used for prevention of mother-to-child HIV transmission (PMTCT) in Botswana. METHODS We extracted obstetric records from all women at the 2 largest maternities in Botswana from 2009-2011 when Botswana National Guidelines recommended zidovudine (ZDV) from 28 weeks gestational age (GA) for CD4 ≥350 and ART for CD4 <350, and again in 2013-2014 after implementation of TDF/FTC/EFV for prevention of mother-to-child HIV transmission regardless of CD4 or GA. We compared the use of TDF/FTC/EFV in pregnancy with other 3-drug ART regimens, and with initiation of ZDV, among women with similar CD4 cell counts. Outcomes included small for gestational age (SGA), preterm delivery (PTD) (<37 weeks GA), and stillbirths (SB). RESULTS Among 9445 HIV-infected women delivering during the study period, 170 were on TDF/FTC/EFV at conception and 1468 initiated TDF/FTC/EFV during pregnancy. Adverse birth outcomes were high overall (3% SB, 21% PTD, and 18% SGA) and among women receiving TDF/FTC/EFV (3% SB, 22% PTD, and 12% SGA). There was no difference in PTD or SB among women initiating TDF/FTC/EFV compared with ZDV or other 3-drug ART, but initiating TDF/FTC/EFV was associated with fewer SGA infants than other 3-drug ART (adjusted odds ratio: 0.4, 95% confidence interval: 0.2 to 0.7). CONCLUSIONS Adverse birth outcomes remain high among HIV-infected women. TDF/FTC/EFV was at least as safe as other ART and associated with fewer SGA infants when initiated during pregnancy. Larger studies are needed to evaluate birth outcomes and congenital abnormalities among women on TDF/FTC/EFV at conception.

Fundamental concerns of women living with HIV around the implementation of Option B+. J Int AIDS Soc 2015; 18:20286.

Abstract
Introduction In 2011, the Global Plan towards the Elimination of New HIV Infections among Children by 2015 and Keeping Their Mothers Alive was launched to scale up efforts to comprehensively end vertical HIV transmission and support mothers living with HIV in remaining healthy. Amidst excitement around using treatment as prevention, Malawi's Ministry of Health conceived Option B+, a strategy used to prevent vertical transmission by initiating all pregnant and breastfeeding women living with HIV on lifelong antiretroviral therapy, irrespective of CD4 count. In 2013, for programmatic and operational reasons, the WHO officially recommended Option B+ to countries with generalized epidemics, limited access to CD4 testing, limited partner testing, long breastfeeding duration or high fertility rates. Discussion While acknowledging the opportunity to increase treatment access globally and its potential, this commentary reviews the concerns of women living with HIV about human rights, community-based support and other barriers to service uptake and retention in the Option B+ context. Option B+ intensifies many of the pre-existing challenges of HIV prevention and treatment programmes. As women seek comprehensive services to prevent vertical transmission, they can experience various human rights violations, including lack of informed consent, involuntary or coercive HIV testing, limited treatment options, termination of pregnancy or coerced sterilization and pressure to start treatment. Yet, peer and community support strategies can promote treatment readiness, uptake, adherence and lifelong retention in care; reduce stigma and discrimination; and mitigate potential violence stemming from HIV disclosure. Ensuring available and accessible quality care, offering food support and improving linkages to care could increase service uptake and retention. With the heightened focus on interventions to reach pregnant and breastfeeding women living with HIV, a parallel increase in vigilance to secure their health and rights is critical. Conclusion The authors conclude that real progress towards reducing vertical transmission and achieving viral load suppression can only be made by upholding the human rights of women living with HIV, investing in community-based responses, and ensuring universal access to quality healthcare. Only then will the opportunity of accessing lifelong treatment result in improving the health, dignity and lives of women living with HIV, their children and families.

Tracing defaulters in HIV prevention of mother-to-child transmission programmes through community health workers: results from a rural setting in Zimbabwe. J Int AIDS Soc 2015; 18:20022.

Abstract
Introduction High retention in care is paramount to reduce vertical human immunodeficiency virus (HIV) infections in prevention of mother-to-child transmission (PMTCT) programmes but remains low in many sub-Saharan African countries. We aimed to assess the effects of community health worker–based defaulter tracing (CHW-DT) on retention in care and mother-to-child HIV transmission, an innovative approach that has not been evaluated to date. Methods We analyzed patient records of 1878 HIV-positive pregnant women and their newborns in a rural PMTCT programme in the Tsholotsho district of Zimbabwe between 2010 and 2013 in a retrospective cohort study. Using binomial regression, we compared vertical HIV transmission rates at six weeks post-partum, and retention rates during the perinatal PMTCT period (at delivery, nevirapine [NVP] initiation at three days post-partum, cotrimoxazole (CTX) initiation at six weeks post-partum, and HIV testing at six weeks post-partum) before and after the introduction of CHW-DT in the project. Results Median maternal age was 27 years (inter-quartile range [IQR] 23 to 32) and median CD4 count was 394 cells/µL3 (IQR 257 to 563). The covariate-adjusted rate ratio (aRR) for perinatal HIV transmission was 0.72 (95% confidence intervals [95% CI] 0.27 to 1.96, p=0.504), comparing patient outcomes after and before the intervention. Among fully retained patients, 11 (1.9%) newborns tested HIV positive. ARRs for retention in care were 1.01 (95% CI 0.96 to 1.06, p=0.730) at delivery; 1.35 (95% CI 1.28 to 1.42, p<0.001) at NVP initiation; 1.78 (95% CI 1.58 to 2.01, p<0.001) at CTX initiation; and 2.54 (95% CI 2.20 to 2.93, p<0.001) at infant HIV testing. Cumulative retention after and before the intervention was 496 (85.7%) and 1083 (87.3%) until delivery; 480 (82.9%) and 1005 (81.0%) until NVP initiation; 303 (52.3%) and 517 (41.7%) until CTX initiation; 272 (47.0%) and 427 (34.4%) until infant HIV testing; and 172 (29.7%) and 405 (32.6%) until HIV test result collection. Conclusions The CHW-DT intervention did not reduce perinatal HIV transmission significantly. Retention improved moderately during the post-natal period, but cumulative retention decreased rapidly even after the intervention. We showed that transmission in resource-limited settings can be as low as in resource-rich countries if patients are fully retained in care. This requires structural changes to the regular PMTCT services, in which community health workers can, at best, play a complementary role.

Abstract
With the world’s largest national treatment programme and over 340 000 incident cases annually, the response to HIV in South Africa is hotly contested and there is sometimes a dissonance between activism, science and policy. Too often, policy, whilst well intentioned, is informed only by epidemiological data. The state of the healthcare system and sociocultural factors drive and shape the epidemic and its response. By analysis of the financial, infrastructural, human resources for health, and governance landscape in South Africa, we assess the feasibility and associated costs of implementing a universal test and treat programme. We situate a universal test and treat strategy within the governance, fiscal, human resources for health, and infrastructural landscape in South Africa. We argue that the response to the epidemic must be forward thinking, progressive and make the most of the benefits from treatment as prevention. However, the logistics of implementing a universal test and treat strategy mean that this option is problematic in the short term. We recommend a health systems strengthening HIV treatment and prevention approach that includes scaling up treatment (for treatment and prevention) along with a range of other prevention strategies.

Abstract
BACKGROUND Approaches to antiretroviral therapy (ART) in HIV-infected pregnant women have changed considerably in recent years, but there are few comparative data on the implementation of different models of service delivery. METHODS Using routine clinic records we examined ART initiation in pregnant women attending a large antenatal care (ANC) facility between January 2010 and December 2013 in Cape Town, South Africa. Over this time six different service delivery models were implemented sequentially to provide ART in pregnancy, including the integration of ART into ANC, use of point-of-care CD4 cell count testing, and universal ART initiation for all HIV-infected pregnant women. RESULTS During the study period 19,432 women sought ANC, levels of HIV testing were high (98%) and 30% of pregnant women tested HIV-positive. Integration of ART into ANC was associated with significant increases in the proportion of eligible women initiating treatment before delivery compared to referral to a separate ART clinic (p<0.001). When CD4 cell counts were used to determine ART eligibility, point-of-care testing was associated with decreased delays to ART initiation compared to laboratory-based testing (p<0.001). The strategy of universal ART led to the highest levels of ART initiation (with 92% of women starting before delivery) and the shortest delays, with 82% of women starting ART on the day of the first ANC visit. CONCLUSION Developments in service delivery models, most notably service integration and universal ART for pregnant women, have improved antenatal ART initiation dramatically in this setting. Further research is needed into how strategies for antenatal ART initiation impact maternal and child health over the long-term.

Abstract
Almost 30% of pregnant women attending public health clinics in South Africa are HIV positive; which represents approximately 280,000 women each year. South Africa has the largest antiretroviral therapy programme in the world, with over 2.7 million people on treatment in 2013. Since its belated and controversial beginning, the Prevention of Mother-to-Child Transmission programme has achieved a substantial reduction in vertical transmission. South Africa is justifiably proud of this success. However, the history of Prevention of Mother-to-Child Transmission (PMTCT) and antiretroviral therapy programmes in South Africa has been fraught with delays and political intervention. South Africa could have started both PMTCT and antiretroviral therapy programmes in 2000. Instead, the AIDS denialist views of the government allowed the HIV epidemic to spiral out of control. Roll-out of a national PMTCT programme began in 2002, but only after the government was forced to do so by a Constitutional Court ruling. Now, a decade later, HIV treatment and prevention programmes have been completely transformed. This article will discuss the evolution of the HIV epidemic in South Africa, and give a historical overview of the struggle to establish a national PMTCT, and the impact of delaying PMTCT and treatment programmes on infant and maternal health.

Abstract
The concept of "treatment as prevention" has emerged as a means to curb the global HIV epidemic. There is, however, still ongoing debate about the evidence on when to start antiretroviral therapy in resource-poor settings. Critics have brought forward multiple arguments against a "test and treat" approach, including the potential burden of such a strategy on weak health systems and a presumed lack of scientific support for individual patient benefit of early treatment initiation. In this article, we highlight the societal and individual advantages of treatment as prevention in resource-poor settings. We argue that the available evidence renders the discussion on when to start antiretroviral therapy unnecessary and that, instead, efforts should be aimed at offering treatment as soon as possible.

Abstract
Background: “Option B+” is a World Health Organization-recommended approach to prevent mother-to-child HIV transmission whereby all HIV-positive pregnant and lactating women initiate lifelong antiretroviral therapy (ART). This review of early Option B+ implementation experience is intended to inform Ministries of Health and others involved in implementing Option B+. Methods: This implementation science study analyzed data from 11 African countries supported by the Elizabeth Glaser Pediatric AIDS Foundation (EGPAF) to describe early experience implementing Option B+. Data are from 4 sources: (1) national guidelines for prevention of mother-to-child HIV transmission and Option B+ implementation plans, (2) aggregated service delivery data between January 2013 and March 2014 from EGPAF-supported sites, (3) field visits to Option B+ implementation sites, and (4) relevant EGPAF research, quality improvement, and evaluation studies. Results: Rapid adoption of Option B+ led to large increases in percentage of HIV-positive pregnant women accessing ART in antenatal care. By the end of 2013, most programs reached at least 50% of HIV-positive women in antenatal care with ART, even in countries using a phased approach to implementation. Scaling up Option B+ through integrating ART in maternal and child health settings has required expansion of the workforce, and task shifting to allow nurse-led ART initiation has created staffing pressure on lower-level cadres for counseling and community follow-up. Complex data collection needs may be impairing data quality. Discussion: Early experiences with Option B+ implementation demonstrate promise. Continued program evaluation is needed, as is specific attention to counseling and support around initiation of lifetime ART in the context of pregnancy and lactation.

Abstract
OBJECTIVE The aim of this study was to determine the level of adherence to Option B+ PMTCT drugs and factors associated with adherence among HIV-positive pregnant women in public hospitals of Tigray, northern Ethiopia. METHODS A cross-sectional study was conducted among 277 HIV-positive pregnant women in 2014. A two-stage cluster sampling technique was used to select the study participants. Individual consent was obtained from each participant. Multivariate logistic regression was used to estimate the net effect sizes of factors associated with adherence to Option B+ PMTCT drugs. RESULTS The level of adherence of respondents to Option B+ PMTCT drugs was 87.1% (95% confidence interval (CI) 82.6-90.7%). Controlling for the effect of other factors, the odds of adhering to Option B+ PMTCT were 4.7 times higher among women who received counselling on medication as compared to those who did not (adjusted odds ratio (aOR) 4.7, 95% CI 1.98-11.35). Similarly, disclosing HIV status was positively associated with good adherence (aOR 4.2, 95% CI 1.07-16.33). CONCLUSIONS The adherence level was found to be reasonably good. Counselling on medication and HIV status disclosure were positive predictors of adherence to Option B+ PMTCT drugs.

Abstract
Background Family planning is an important HIV prevention tool for women living with HIV (WLHIV). In Mozambique, the prevalence of HIV among women of reproductive age is 13.1% and the average fertility rate is high. However, family planning and reproductive health for WLHIV are under-addressed in Mozambique. This study explores provider descriptions of reproductive health messages in order to identify possible barriers and facilitators to successfully addressing family planning and pregnancy concerns of WLHIV. Methods In 2006, a Positive Health, Dignity, and Prevention program was introduced in Mozambique focused on training health care providers to work with patients to reduce their transmission risks. Providers received training on multiple components, including family planning and prevention of mother-to-child transmission (PMTCT). In-depth interviews were conducted with 31 providers who participated in the training in five rural clinics in three provinces. Data were analyzed using qualitative content analysis. Results Analysis showed that providers’ clinical messages on family planning, pregnancy, and PMTCT for WLHIV could be arranged along a continuum. Provider statements ranged from saying that WLHIV should not become pregnant and condoms are the only valid form of family planning for WLHIV, to suggesting that WLHIV can have safe pregnancies. Conclusion These data indicate that many providers continue to believe that WLHIV should not have children and this represents a challenge for integrating family planning into the care of WLHIV. Also, not offering WLHIV a full selection of family planning methods severely limits their ability to protect themselves from unintended pregnancies and to fully exercise their reproductive rights. Responding to the reproductive health needs of WLHIV is a critical component in HIV prevention and could increase the success of PMTCT programs.

Abstract
BACKGROUND Despite progress reducing maternal mortality, HIV-related maternal deaths remain high, accounting, for example, for up to 24 percent of all pregnancy-related deaths in sub-Saharan Africa. Antiretroviral therapy (ART) is effective in improving outcomes among HIV-infected pregnant and postpartum women, yet rates of initiation, adherence, and retention remain low. This systematic literature review synthesized evidence about individual and contextual factors affecting ART use among HIV-infected pregnant and postpartum women. METHODS Searches were conducted for studies addressing the population (HIV-infected pregnant and postpartum women), intervention (ART), and outcomes of interest (initiation, adherence, and retention). Quantitative and qualitative studies published in English since January 2008 were included. Individual and contextual enablers and barriers to ART use were extracted and organized thematically within a framework of individual, interpersonal, community, and structural categories. RESULTS Thirty-four studies were included in the review. Individual-level factors included both those within and outside a woman's awareness and control (e.g., commitment to child's health or age). Individual-level barriers included poor understanding of HIV, ART, and prevention of mother-to-child transmission, and difficulty managing practical demands of ART. At an interpersonal level, disclosure to a spouse and spousal involvement in treatment were associated with improved initiation, adherence, and retention. Fear of negative consequences was a barrier to disclosure. At a community level, stigma was a major barrier. Key structural barriers and enablers were related to health system use and engagement, including access to services and health worker attitudes. CONCLUSIONS To be successful, programs seeking to expand access to and continued use of ART by integrating maternal health and HIV services must identify and address the relevant barriers and enablers in their own context that are described in this review. Further research on this population, including those who drop out of or never access health services, is needed to inform effective implementation.

Abstract
Prevention of mother to child transmission of HIV can virtually eliminate paediatric HIV infection. Studies are needed to understand child development outcomes for children exposed to HIV in utero but born HIV negative (HIV affected children). This systematic review examined cognitive, developmental and behavioural outcomes for HIV affected children compared to control unexposed and uninfected children. Key word searches of electronic databases generated 1,739 hits and 11 studies with adequate quality design and measures of standardised cognitive, behavioural and developmental indices. Cognitive performance, behaviour and developmental delay were measured with 15 different standardised scales from 650 HIV affected children, 736 control children and 205 HIV positive children. Performance scores for HIV affected children were significantly lower than controls in at least one measure in 7/11 studies. An emerging pattern of delay seems apparent. HIV affected children will grow in number and their development needs to be monitored and provided for.

A systematic review of health system barriers and enablers for antiretroviral therapy (ART) for HIV-infected pregnant and postpartum women. PLoS One 2014; 9:e108150. [PMID: 25303241 PMCID: PMC4193745 DOI: 10.1371/journal.pone.0108150] [Citation(s) in RCA: 100] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2014] [Accepted: 08/25/2014] [Indexed: 11/29/2022] Open
Abstract
Background Despite global progress in the fight to reduce maternal mortality, HIV-related maternal deaths remain persistently high, particularly in much of Africa. Lifelong antiretroviral therapy (ART) appears to be the most effective way to prevent these deaths, but the rates of three key outcomes—ART initiation, retention in care, and long-term ART adherence—remain low. This systematic review synthesized evidence on health systems factors affecting these outcomes in pregnant and postpartum women living with HIV. Methods Searches were conducted for studies addressing the population of interest (HIV-infected pregnant and postpartum women), the intervention of interest (ART), and the outcomes of interest (initiation, adherence, and retention). Quantitative and qualitative studies published in English since January 2008 were included. A four-stage narrative synthesis design was used to analyze findings. Review findings from 42 included studies were categorized according to five themes: 1) models of care, 2) service delivery, 3) resource constraints and governance challenges, 4) patient-health system engagement, and 5) maternal ART interventions. Results Low prioritization of maternal ART and persistent dropout along the maternal ART cascade were key findings. Service delivery barriers included poor communication and coordination among health system actors, poor clinical practices, and gaps in provider training. The few studies that assessed maternal ART interventions demonstrated the importance of multi-pronged, multi-leveled interventions. Conclusions There has been a lack of emphasis on the experiences, needs and vulnerabilities particular to HIV-infected pregnant and postpartum women. Supporting these women to successfully traverse the maternal ART cascade requires carefully designed and targeted interventions throughout the steps. Careful design of integrated service delivery models is of critical importance in this effort. Key knowledge gaps and research priorities were also identified, including definitions and indicators of adherence rates, and the importance of cumulative measures of dropout along the maternal ART cascade.

Universal combination antiretroviral regimens to prevent mother-to-child transmission of HIV in rural Zambia: a two-round cross-sectional study. Bull World Health Organ 2014; 92:582-92. [PMID: 25177073 DOI: 10.2471/blt.13.129833] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2013] [Revised: 02/28/2014] [Accepted: 03/04/2014] [Indexed: 11/27/2022] Open
Abstract
OBJECTIVE To evaluate if a pilot programme to prevent mother-to-child transmission (PMTCT) of the human immunodeficiency virus (HIV) was associated with changes in early childhood survival at the population level in rural Zambia. METHODS Combination antiretroviral regimens were offered to pregnant and breastfeeding, HIV-infected women, irrespective of immunological status, at four rural health facilities. Twenty-four-month HIV-free survival among children born to HIV-infected mothers was determined before and after PMTCT programme implementation using community surveys. Households were randomly selected and women who had given birth in the previous 24 months were asked to participate. Mothers were tested for HIV antibodies and children born to HIV-infected mothers were tested for viral deoxyribonucleic acid. Multivariable models were used to determine factors associated with child HIV infection or death. FINDINGS In the first survey (2008-2009), 335 of 1778 women (18.8%) tested positive for HIV. In the second (2011), 390 of 2386 (16.3%) tested positive. The 24-month HIV-free survival in HIV-exposed children was 0.66 (95% confidence interval, CI: 0.63-0.76) in the first survey and 0.89 (95% CI: 0.83-0.94) in the second. Combination antiretroviral regimen use was associated with a lower risk of HIV infection or death in children (adjusted hazard ratio: 0.33, 95% CI: 0.15-0.73). Maternal knowledge of HIV status, use of HIV tests and use of combination regimens during pregnancy increased between the surveys. CONCLUSION The PMTCT programme was associated with an increased HIV-free survival in children born to HIV-infected mothers. Maternal utilization of HIV testing and treatment in the community also increased.

Attitudes of people in the UK with HIV who Are Antiretroviral (ART) Naïve to starting ART at high CD4 counts for potential health benefit or to prevent HIV transmission. PLoS One 2014; 9:e97340. [PMID: 24869805 PMCID: PMC4037177 DOI: 10.1371/journal.pone.0097340] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2013] [Accepted: 04/18/2014] [Indexed: 11/18/2022] Open
Abstract
OBJECTIVE To assess if a strategy of early ART to prevent HIV transmission is acceptable to ART naïve people with HIV with high CD4 counts. DESIGN ASTRA is a UK multicentre, cross sectional study of 3258 HIV outpatients in 2011/12. A self-completed questionnaire collected sociodemographic, behavioral and health data, and attitudes to ART; CD4 count was recorded from clinical records. METHODS ART naïve participants with CD4 ≥350 cells/µL (n = 281) were asked to agree/disagree/undecided with the statements (i) I would want to start treatment now if this would slightly reduce my risk of getting a serious illness, and (ii) I would want to start treatment now if this would make me less infectious to a sexual partner, even if there was no benefit to my own health. RESULTS Participants were 85% MSM, 76% white, 11% women. Of 281 participants, 49.5% and 45.2% agreed they would start ART for reasons (i) and (ii) respectively; 62.6% agreed with either (i) or (ii); 12.5% agreed with neither; 24.9% were uncertain. Factors independently associated (p<0.1) with agreement to (i) were: lower CD4, more recent HIV diagnosis, physical symptoms, not being depressed, greater financial hardship, and with agreement to (ii) were: being heterosexual, more recent HIV diagnosis, being sexually active. CONCLUSIONS A strategy of starting ART at high CD4 counts is likely to be acceptable to the majority of HIV-diagnosed individuals. Almost half with CD4 >350 would start ART to reduce infectiousness, even if treatment did not benefit their own health. However a significant minority would not like to start ART either for modest health benefit or to reduce infectivity. Any change in approach to ART initiation must take account of individual preferences. Transmission models of potential benefit of early ART should consider that ART uptake may be lower than that seen with low CD4 counts.

Abstract
OBJECTIVE To explore the levels and determinants of loss to follow-up (LTF) under universal lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women ('Option B+') in Malawi. DESIGN, SETTING, AND PARTICIPANTS We examined retention in care, from the date of ART initiation up to 6 months, for women in the Option B+ program. We analysed nationwide facility-level data on women who started ART at 540 facilities (n = 21,939), as well as individual-level data on patients who started ART at 19 large facilities (n = 11,534). RESULTS Of the women who started ART under Option B+ (n = 21,939), 17% appeared to be lost to follow-up 6 months after ART initiation. Most losses occurred in the first 3 months of therapy. Option B+ patients who started therapy during pregnancy were five times more likely than women who started ART in WHO stage 3/4 or with a CD4 cell count 350 cells/μl or less, to never return after their initial clinic visit [odds ratio (OR) 5.0, 95% confidence interval (CI) 4.2-6.1]. Option B+ patients who started therapy while breastfeeding were twice as likely to miss their first follow-up visit (OR 2.2, 95% CI 1.8-2.8). LTF was highest in pregnant Option B+ patients who began ART at large clinics on the day they were diagnosed with HIV. LTF varied considerably between facilities, ranging from 0 to 58%. CONCLUSION Decreasing LTF will improve the effectiveness of the Option B+ approach. Tailored interventions, like community or family-based models of care could improve its effectiveness.
