Abstract
Background Medication adherence in HIV-infected pregnant women remains suboptimal. This systematic review and meta-analysis aimed to evaluate the effectiveness of interventions on improving antiretroviral adherence targeting among HIV-infected pregnant women. Methods Five databases were screened to identify quasi-experimental studies and randomized controlled trials. The risk ratios (RR) and confidential intervals (CI) were extracted to estimate the improvement in antiretroviral adherence after interventions compared with control conditions. This study was registered with PROSPERO, number CRD42021256317. Results Nine studies were included in the review, totaling 2,900 participants. Three interventions had significance: enhanced standard of care (eSOC, RR 1.14, 95%CI 1.07-1.22, Z = 3.79, P < 0.01), eSOC with supporter (RR 1.12, 95%CI 1.04-1.20, Z = 2.97, P < 0.01) and device reminder (RR 1.33, 95%CI 1.04-1.72, Z = 2.23, P = 0.03). Discussion The study supported the eSOC and the device reminder as effective intervention strategies for improving HIV medication adherence. Based on the current findings, the study called for more efforts to improve antiretroviral care for pregnant women through involving multicenter, large-sample, and high-quality research and combining the device reminder with other intervention methods.

Abstract
BACKGROUND Good patient adherence to antiretroviral (ART) medication determines effective HIV viral suppression, and thus reduces the risk of progression and transmission of HIV. With accurate methods to monitor treatment adherence, we could use simple triage to target adherence support interventions that could help in the community or at health centres in resource-limited settings. OBJECTIVES To determine the accuracy of simple measures of ART adherence (including patient self-report, tablet counts, pharmacy records, electronic monitoring, or composite methods) for detecting non-suppressed viral load in people living with HIV and receiving ART treatment. SEARCH METHODS The Cochrane Infectious Diseases Group Information Specialists searched CENTRAL, MEDLINE, Embase, LILACS, CINAHL, African-Wide information, and Web of Science up to 22 April 2021. They also searched the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov for ongoing studies. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA We included studies of all designs that evaluated a simple measure of adherence (index test) such as self-report, tablet counts, pharmacy records or secondary database analysis, or both, electronic monitoring or composite measures of any of those tests, in people living with HIV and receiving ART treatment. We used a viral load assay with a limit of detection ranging from 10 copies/mL to 400 copies/mL as the reference standard. We created 2 × 2 tables to calculate sensitivity and specificity. DATA COLLECTION AND ANALYSIS We screened studies, extracted data, and assessed risk of bias using QUADAS-2 independently and in duplicate. We assessed the certainty of evidence using the GRADE method. The results of estimated sensitivity and specificity were presented using paired forest plots and tabulated summaries. We encountered a high level of variation among studies which precluded a meaningful meta-analysis or comparison of adherence measures. We explored heterogeneity using pre-defined subgroup analysis. MAIN RESULTS We included 51 studies involving children and adults with HIV, mostly living in low- and middle-income settings, conducted between 2003 and 2021. Several studies assessed more than one index test, and the most common measure of adherence to ART was self-report. - Self-report questionnaires (25 studies, 9211 participants; very low-certainty): sensitivity ranged from 10% to 85% and specificity ranged from 10% to 99%. - Self-report using a visual analogue scale (VAS) (11 studies, 4235 participants; very low-certainty): sensitivity ranged from 0% to 58% and specificity ranged from 55% to 100%. - Tablet counts (12 studies, 3466 participants; very low-certainty): sensitivity ranged from 0% to 100% and specificity ranged from 5% to 99%. - Electronic monitoring devices (3 studies, 186 participants; very low-certainty): sensitivity ranged from 60% to 88% and the specificity ranged from 27% to 67%. - Pharmacy records or secondary databases (6 studies, 2254 participants; very low-certainty): sensitivity ranged from 17% to 88% and the specificity ranged from 9% to 95%. - Composite measures (9 studies, 1513 participants; very low-certainty): sensitivity ranged from 10% to 100% and specificity ranged from 49% to 100%. Across all included studies, the ability of adherence measures to detect viral non-suppression showed a large variation in both sensitivity and specificity that could not be explained by subgroup analysis. We assessed the overall certainty of the evidence as very low due to risk of bias, indirectness, inconsistency, and imprecision. The risk of bias and the applicability concerns for patient selection, index test, and reference standard domains were generally low or unclear due to unclear reporting. The main methodological issues identified were related to flow and timing due to high numbers of missing data. For all index tests, we assessed the certainty of the evidence as very low due to limitations in the design and conduct of the studies, applicability concerns and inconsistency of results. AUTHORS' CONCLUSIONS We encountered high variability for all index tests, and the overall certainty of evidence in all areas was very low. No measure consistently offered either a sufficiently high sensitivity or specificity to detect viral non-suppression. These concerns limit their value in triaging patients for viral load monitoring or enhanced adherence support interventions.

Prevalence of depression among HIV-positive pregnant women and its association with adherence to antiretroviral therapy in Addis Ababa, Ethiopia. PLoS One 2022; 17:e0262638. [PMID: 35051244 PMCID: PMC8775187 DOI: 10.1371/journal.pone.0262638] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Accepted: 01/03/2022] [Indexed: 11/19/2022] Open
Abstract
Background
Vertical transmission of HIV remains one of the most common transmission modes. Antiretroviral therapy (ART) decreases the risk of transmission to less than 2%, but maintaining adherence to treatment remains a challenge. Some of the commonly reported barriers to adherence to ART include stress (physical and emotional), depression, and alcohol and drug abuse. Integrating screening and treatment for psychological problem such as depression was reported to improve adherence. In this study, we sought to determine the prevalence of depression and its association with adherence to ART among HIV-positive pregnant women attending antenatal care (ANC) clinics in Addis Ababa, Ethiopia.
Methods
We conducted a cross-sectional survey from March through November 2018. Participants were conveniently sampled from 12 health institutions offering ANC services. We used the Patient Health Questionnaire-9 (PHQ-9) to screen for depression and the Center for Adherence Support Evaluation (CASE) Adherence index to evaluate adherence to ART. Descriptive statistics was used to estimate the prevalence of depression during third-trimester pregnancy and nonadherence to ART. A bivariate logistic regression analysis was used to get significant predictors for each of the two outcome measures. The final multivariable logistic regression analysis included variables with a P<0.25 in the bivariate logistic regression model; statistical significance was evaluated at P<0.05.
Results
We approached 397 eligible individuals, of whom 368 (92.7%) participated and were included in the analysis. Of the total participants, 175(47.6%) had depression. The participants’ overall level of adherence to ART was 82%. Pregnant women with low income were twice more likely to have depression (AOR = 2.10, 95%CI = 1.31–3.36). Women with WHO clinical Stage 1 disease were less likely to have depression than women with more advanced disease (AOR = 0.16, 95%CI = 0.05–0.48). There was a statistically significant association between depression and nonadherence to ART (P = 0.020); nonadherence was nearly two times higher among participants with depression (AOR = 1.88, 95%CI = 1.08–3.27).
Conclusion
We found a high prevalence of depression among HIV-positive pregnant women in the selected health facilities in Addis Ababa, and what was more concerning was its association with higher rates of nonadherence to ART adversely affecting the outcome of their HIV care. We recommend integrating screening for depression in routine ANC services.

Abstract
We assessed the preliminary impact of the adapted HIV Infant Tracking System (HITSystem v2.0) intervention on prevention of mother-to-child transmission (PMTCT) outcomes using a matched cluster randomized design in two Kenyan government hospitals. Between November 2017 and June 2019, n = 157 pregnant women with HIV were enrolled and followed from their first PMTCT appointment until 12-weeks postpartum. Data from 135 women were analyzed (HITSystem 2.0: n = 53, standard of care (SOC): n = 82), excluding eight deaths, eight pregnancy losses, and six transfers/moves. The primary outcome, complete PMTCT retention, is an aggregate measure of attendance at all scheduled antenatal appointments, hospital-based delivery, and infant HIV-testing before 7-weeks postnatal. HITSystem 2.0 participants were more likely to receive complete PMTCT services compared to SOC (56.6% vs. 17.1% p < 0.001). In multivariate modeling, HITSystem 2.0 was the strongest predictor of complete PMTCT retention (aOR 5.7, [1.2-90.8], p = 0.032). SOC participants had 1.91 increased hazard rate of PMTCT disengagement; (aHR 6.8, [2.2-21.1]; p < 0.001).

Abstract
Background Currently, around 36.7 million people in the world are living with HIV. Among these, 52% are living in sub-Saharan Africa. The main objective of this study was to identify socio-demographic economic and clinical factors associated with HAART adherence competence in successive visits among adult HIV patients after commencement of their treatment. Methods A retrospective cohort study design was conducted on a random sample of 792 treatment attendants. The samples were selected using stratified random samples technique considering their residence area as strata. Secondary data were used in this study. Structural equation modeling (SEM) was applied to identify predictors of HAART adherence competence over time. Results In this longitudinal study, factors affecting long-term HAART adherence competence in successive visits were identified. Among the predictors, marital status (mean = 3.97, variance = 0.6, p = 0.021), level of disclosure of the disease (mean = 6.24, variance = 0.29, p = 0.012), residence area (mean = 3.97, variance = 0.6, p = 0.021), level of education (mean = 2.04, variance= 0.81, p = 0.012), ownership of cell phone (mean = 2.99, variance = 0.68, p = 0.034), household income (mean = 6.37, variance = 0.53, p = 0.002), age of patients (mean = –2.78, variance = 56.64, p = 0.023), sex of patients (mean = –1.25, variance = 0.88, p = 0.036), weight (mean = –2.89, 42.36, p = 0.001), initial CD4 cell count (mean = 2.57, variance = 158.48, p = 0.015) and WHO stages (mean = 2.37, variance = 0.78, p = 0.026) were directly associated with retention of medication care. On the other hand, medication care was significantly and independently associated with longitudinal adherence competence. Conclusion The outcome variable in successive visits increased with the number of follow-up visits, but the rate of increase was different for different groups, such as urban and rural, and for those patients disclosing and not disclosing the disease to family members. An integrated health-related education should be given for non-adherent patients like rural residents, patients living without partners, patients with no cell phone and aged patients.

What influences uptake and early adherence to Option B+ (lifelong antiretroviral therapy among HIV positive pregnant and breastfeeding women) in Central Uganda? A mixed methods study. PLoS One 2021; 16:e0251181. [PMID: 33951109 PMCID: PMC8099116 DOI: 10.1371/journal.pone.0251181] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Accepted: 04/21/2021] [Indexed: 11/25/2022] Open
Abstract
Background High uptake and optimal adherence to Option B+ antiretroviral therapy (ART) increase effectiveness in averting mother-to-child transmission of HIV. Option B+ ART uptake, early adherence, and associated factors need to be evaluated in Central Uganda. Methods A mixed approaches study was carried out in six health facilities in Masaka, Mityana, and Luwero districts from October 2013 to February 2016. Questionnaires were administered to 507 HIV positive pregnant females seeking antenatal care services. Key informant interviews were conducted with 54 health providers, and in-depth interviews (IDIs) with 57 HIV positive women on Option B+ ART. Quantitative data were analyzed using log-binomial regression model to determine factors associated with optimal adherence (taking at least 95% of the prescribed ART), while thematic analysis was used on qualitative data. Results Ninety one percent of women (463/507) received a prescription of life long ART. Of these, 93.3% (432/463) started swallowing their medicines. Overall, 83% of women who received ART prescriptions (310/374) felt they were ready to initiate ART immediately. Main motivating factors to swallow ART among those who received a prescription were women’s personal desire to be healthy (92.3%) and desire to protect their babies (90.6%). Optimal adherence to ART was achieved by 76.8% (315/410). Adherence was higher among females who were ready to start ART (adj. PR = 3.20; 95% CI: 1.15–8.79) and those who had revealed their HIV positive result to someone (adj. PR = 1.23; 95% CI: 1.04–1.46). Facilitators of ART uptake from qualitative findings included adequate counseling, willingness to start, and knowing the benefits of ART. Reasons for refusal to start ART included being unready to start ART, fear to take ART for life, doubt of HIV positive results, and preference for local herbs. Reasons for non-adherence were travelling far away from health facilities, fear of side effects, non-disclosure of HIV results to anyone, and perception that the baby is safe from HIV infection post-delivery. Conclusions Uptake of Option B+ ART was very high. However, failure to start swallowing ART and sub-optimal adherence are a major public health concern. Enhancing women’s readiness to start ART and encouraging HIV result revelation could improve ART uptake and adherence.

Abstract
Background This research advances understanding of interrelationships among three barriers to adherence to antiretroviral therapy (ART) among pregnant women living with HIV (WLWH) in Cameroon: probable common mental disorders (CMD), intimate partner violence (IPV), and hunger. Methods The sample included 220 pregnant WLWH in Cameroon. Multivariable modified Poisson regression was conducted to assess the relationship between IPV, hunger, and CMD on ART adherence. Results Almost half (44%) of participants recently missed/mistimed an ART dose. Probable CMD was associated with greater risk of missed/mistimed ART dose (aRR 1.5 [95% CI 1.1, 1.9]). Hunger was associated with greater risk of missed/mistimed ART dose among those who reported IPV (aRR 1.9 [95% CI 1.2, 2.8]), but not among those who did not (aRR 0.8 [95% CI 0.2, 2.3]). Conclusion Suboptimal ART adherence, CMD, and IPV were common among pregnant WLWH in Cameroon. Pregnant WLWH experiencing IPV and hunger may be especially vulnerable to suboptimal ART adherence.

[PMID: 33239922 PMCID: PMC7682779 DOI: 10.2147/hiv.s282463] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Accepted: 11/10/2020] [Indexed: 11/23/2022] Open
Abstract
Purpose Even if progressive efforts were made in Ethiopia, half of new HIV infections result from mother-to-child transmission. Limited studies assessed the level and factors of adherence that differ among different populations across the country. So, this study aimed to investigate the level and predictors of adherence to the prevention of mother-to-child transmission (PMTCT) Option B+ care among pregnant women in central Ethiopia. Methods A facility-based cross-sectional study design was conducted to interview 347 HIV positive pregnant women. Using a multistage sampling technique, participants were recruited from twelve health facilities based on probability proportional to the number of clients. The collected data on socio-demographics, healthcare delivery, clinical and individual factors were entered into EpiInfo v7.2.2.6, and further analysis was done using SPSS v23 software. Adherence was measured based on client self-report either as adherent and non-adherent. Bivariate and multivariate logistic regressions were undertaken to see the association between variables. Statistically significant variables were declared using an adjusted odds ratio with a 95% confidence interval. Results The overall adherence to option B+ was 80.2% (95% CI: 76.3–84.5%). Time of ART initiation (AOR=3.23; 95% CI: 1.09–6.59), fear of stigma for taking ARV (AOR=5.06; 95% CI: 1.79–10.26), ANC appointment (AOR=4.62; 95% CI: 1.48–6.42), male partner support (AOR=2.23; 95% CI: 1.11–4.50), and counseling (AOR=5.36: 95% CI: 1.00–8.58) were the associated factors with level of adherence. Conclusion The overall adherence level to Option B+ care in this study was inadequate to suppress the viral load during pregnancy. The result revealed that keeping adherence to ARVs during pregnancy is still challenging. So, all concerned bodies need to give attention to minimize the barriers from the client, environment, and health system perspectives.

Adapting the HIV Infant Tracking System to Support Prevention of Mother-to-Child Transmission of HIV in Kenya: Protocol for an Intervention Development Pilot Study in Two Hospitals. JMIR Res Protoc 2019; 8:e13268. [PMID: 31199305 PMCID: PMC6592400 DOI: 10.2196/13268] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2018] [Revised: 04/16/2019] [Accepted: 04/16/2019] [Indexed: 01/10/2023] Open
Abstract
Background Despite progress to expand access to HIV testing and treatment during pregnancy in Kenya, gaps still remain in prevention of mother-to-child transmission of HIV (PMTCT) services. This study addresses the need for effective and scalable interventions to support women throughout the continuum of care for PMTCT services in low-resource settings. Our research team has successfully implemented the HIV Infant Tracking System (HITSystem), a Web-based, system-level intervention to improve early infant diagnosis (EID) outcomes. Objective This study will expand the scope of the HITSystem to address PMTCT services to bridge the gap between maternal and pediatric HIV services and improve outcomes. This paper describes the intervention development protocol to adapt and pilot an HITSystem version 2.0 to assess acceptability, feasibility, and preliminary PMTCT outcomes in Kenya. Methods This is a 3-year intervention development study to adapt the current HITSystem intervention to support a range of PMTCT outcomes including appointment attendance, antiretroviral therapy (ART) adherence, hospital deliveries, and integration of maternal and pediatric HIV services in low-resource settings. The study will be conducted in 3 phases. Phase 1 will elicit feedback from intervention users (patients and providers) to guide development and refinement of the new PMTCT components and inform optimal implementation. In Phase 2, we will design and develop the HITSystem 2.0 features to support key PMTCT outcomes guided by clinical content experts and findings from Phase 1. Phase 3 will assess complete PMTCT retention (before, during, and after delivery) using a matched randomized pilot study design in 2 hospitals over 18 months. A total of N=108 HIV-positive pregnant women (n=54 per site) will be enrolled and followed from their first PMTCT appointment until infant HIV DNA Polymerase Chain Reaction testing at the target age of 6 weeks (<7 weeks) postnatal. Results Funding for this study was received in August 2015, enrollment in Phase 1 began in March 2016, and completion of data collection is expected by May 2019. Conclusions This protocol will extend, adapt, and pilot an HITSystem 2.0 version to improve attendance of PMTCT appointments, increase ART adherence and hospital-based deliveries, and prompt EID by 6 weeks postnatal. The HITSystem 2.0 aims to improve the integration of maternal and pediatric HIV services.

Abstract
OBJECTIVE To assess the association between timing of maternal combination ART (cART) initiation and stillbirth among HIV-infected pregnant women in Malawi's Option B+ programme. METHODS Cohort study of HIV-infected pregnant women delivering singleton live or stillborn babies at ≥28 weeks of gestation using routine data from maternity registers between 1 January 2012 and 30 June 2015. We defined stillbirth as death of a foetus at ≥28 weeks of gestation. We report proportions of stillbirth according to timing of maternal cART initiation (before pregnancy, 1st or 2nd trimester, or 3rd trimester or labour). We used logistic regression, with robust standard errors to account for clustering of women within health facilities, to investigate the association between timing of cART initiation and stillbirth. RESULTS Of 10 558 mother-infant pairs abstracted from registers, 8380 (79.4%) met inclusion criteria. The overall rate of stillbirth was 25 per 1000 deliveries (95% confidence interval 22-29). We found no significant association between timing of maternal cART initiation and stillbirth. In multivariable models, older maternal age, male sex of the infant, breech vaginal delivery, delivery at < 34 weeks of gestation and experience of any maternal obstetric complication were associated with higher odds of stillbirth. Deliveries managed by a mission hospital or health centre were associated with lower odds of stillbirth. CONCLUSION Pregnant women's exposure to cART, regardless of time of its initiation, was not associated with increased odds of stillbirth.

Abstract
Background The Option B+ strategy streamlines delivery of HIV antiretroviral therapy (ART) to pregnant women, but concerns remain about ART treatment adherence and long term outcomes. Methods We conducted a retrospective analysis of a cohort of HIV-positive, postpartum breastfeeding women receiving ART via Option B+ in Nairobi, Kenya. The primary outcome was virologic failure in plasma (HIV RNA >1000 copies/mL), and detection in breast milk (>150 copies/mL) and endocervical secretions (>100 copies/mL) at 2 postpartum timepoints. Correlates of virologic failure were assessed using univariate tests and multivariate logistic regression. Results Of 42 women at 6–14 weeks postpartum, 21.4% of women had HIV RNA detected in plasma; 14.3% in breast milk, and 23.7% in endocervical secretions. At 18–24 weeks postpartum, the percentages were 21.1%, 7.1%, and 14.3%, respectively. Younger maternal age, intent to breastfeed for longer, and later ART start in pregnancy were significantly associated with plasma virologic failure (p < 0.05 for each). Odds of plasma virologic failure at 6–14 weeks postpartum were 1.25 times higher (95% CI 1.04, 1.51) for each increase in week of gestation at ART initiation. Only 3 women had resistance mutations to their regimen. Conclusions Despite months of ART, nearly one-quarter of the women in our cohort did not achieve plasma virologic suppression in the postpartum period. After adjusting for time on ART, earlier ART initiation in pregnancy was significantly associated with plasma suppression. Our findings suggest that postpartum HIV RNA monitoring in Option B+ programs will be needed to achieve elimination of MTCT.

PLoS One 2019; 14:e0212587. [PMID: 30794633 PMCID: PMC6386496 DOI: 10.1371/journal.pone.0212587] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2018] [Accepted: 02/05/2019] [Indexed: 11/18/2022] Open
Abstract
Background Adherence to option B+ antiretroviral treatment (ART) is vital to a successful implementation of Prevention of Mother to Child Transmission (PMTCT) program. Further studies show that optimal viral suppression is also crucial for a successful PMTCT program, however barriers to adherence exist and differ among populations and particularly within few years of its adoption in Tanzania. This study therefore aimed at investigating the level and predictors of adherence to ART option B+ among pregnant and lactating women in rural and urban settings of eastern Tanzania. Methodology A cross-sectional study was conducted among 305 pregnant women and lactating mothers on Option B+ regime from six health facilities located in rural and urban settings in Morogoro region in eastern Tanzania. Data were collected using a structured questionnaire. Data analysis was performed using descriptive statistics, as well as bivariate and multivariate logistic regression. Results Good adherence to option B+ PMTCT drugs was 26.3% and 61.1% among respondents residing in urban and rural areas respectively. The rural residents were 4.86 times more likely to adhere compared to their counterparts in an urban area (aOR = 4.86; 95% CI = 2.91–8.13). Similarly, women with male partners’ support in PMTCT were 3.51 times more likely to have good adherence than those without (aOR = 3.51, 95% CI = 1.21–10.15). Moreover, there was a significantly lower odds of adherence to option B+ among those who had been on treatment between one to two years as compared to those had less than one year of treatment (aOR = 0.45; 95%CI = 0.22–0.93). Conclusion Adherence to PMTCT option B+ antiretroviral drugs treatment among pregnant women and breastfeeding mothers was low and much lower among urban residents. Adherence was significantly predicted by rural residence, male partner support and short duration on ART. Efforts to improve adherence should focus on increasing male participation on PMTCT, tailored interventions to urban residents and those who have been on ART for a long duration.

Abstract
OBJECTIVE We evaluated the effectiveness of interventions aimed at improving antiretroviral therapy (ART) adherence during pregnancy in sub-Saharan Africa. METHODS For this meta-analysis, the following databases were searched: MEDLINE Complete, Embase, Global Health, CINAHL Complete, and Google Scholar. Randomized and nonrandomized studies were considered for inclusion if they involved an intervention with the intent of improving medication adherence among pregnant women taking ART in sub-Saharan Africa. Databases were searched from inception to the end of August 2017. The primary outcome assessed was adherence to ART, defined as the proportion of women adherent to treatment in the control and intervention groups. Risk ratios and random effect meta-analysis were undertaken, and heterogeneity was examined with the I2 statistic. RESULTS The systematic search of databases yielded a total of 402 articles, of which 19 studies were selected for meta-analysis with a total of 27,974 participants. Nine types of interventions were identified in the 19 studies to improve ART adherence. The test for the subgroup differences showed that there was a statistically significant difference among the 9 subgroups of interventions, χ2 (8)=102.38; p=0.00001. Collectively, in the meta-analysis, the various intervention types made a significant impact on improving medication adherence. The overall effect estimate with 95% CI was as follows: 1.25 (95% CI=1.03, 1.52, p=0.03). The following risk ratio results for meta-analysis were obtained for the three interventions that showed significant impact on adherence; namely social support and structural support, 1.58 (95% CI=1.36, 1.84, p<0.00001); education, social support and structural support=2.60 (95% CI=1.95, 3.45, p<0.00001); and device reminder=1.13 (95% CI=1.05, 1.20, p=0.0004). The proportion of women who were adherent to ART as a result of the interventions was 59.3% compared with 22.5% in the control groups. CONCLUSION The use of device reminder, a combination of social support and structural support, and education, social support and structural support has the potential to improve ART adherence during pregnancy. Good quality prospective observational studies and randomized control trials are needed in sub-Saharan Africa to determine the most effective interventions.

Abstract
BACKGROUND The use of antiretroviral therapy (ART) is a core strategy proposed by the World Health Organization in preventing mother to child transmission (MTCT) of HIV. This systematic review aimed to examine the enablers and barriers of medication adherence among HIV positive pregnant women in sub-Saharan Africa. METHODS We used the following keywords: HIV AND (Pregnancy OR Pregnant*) AND (PMTCT OR "PMTCT Cascade" OR "Vertical Transmission" OR "Mother-to-Child") AND (Prevent OR Prevention) AND (HAART OR "Antiretroviral Therapy" OR "Triple Therapy") AND (Retention OR Concordance OR Adherence OR Compliance) to conduct electronic searches in the following databases: MEDLINE Complete (1916-Dec 2017), Embase (1947-Dec 2017), Global Health (1910-Dec 2017) and CINAHL Complete (1937-Dec 2017). Of the four databases searched, 401 studies were identified with 44 meeting the inclusion criteria. Seven studies were added after searching reference lists of included articles, resulting in 51 articles in total. RESULTS The review demonstrated that stigma, cost of transportation, food deprivation and a woman's disclosure or non-disclosure of her HIV status to a partner, family and the community, could limit or define the extent of her adherence to prescribed antiretroviral drugs during pregnancy. Furthermore, the review indicated that knowledge of HIV status, either before or during pregnancy, was significantly associated with medication adherence. Women who knew their HIV status before pregnancy demonstrated good adherence while women who found out their HIV infection status during pregnancy were linked with non-adherence to ART. CONCLUSION This review revealed several barriers and enablers of adherence among pregnant women taking ART in sub-Saharan Africa. Major barriers included the fear of HIV infection status disclosure to partners and family members, stigma and discrimination. A major enabler of adherence in women taking ART was women's knowledge of their HIV status prior to becoming pregnant. Enhanced effort is needed to facilitate women's knowledge of their HIV status before pregnancy to enable disease acceptance and management, and to support pregnant women and her partner and family in dealing with fear, stigma and discrimination about HIV.

Abstract
Background Context-specific factors influence adherence to antiretroviral therapy (ART) among pregnant women living with HIV. Gaps exist in the understanding of the reasons for the variable outcomes of the prevention of mother-to-child transmission (PMTCT) programme at the health facility level in South Africa. This study examined adherence levels and reasons for non-adherence during pregnancy in a cohort of parturient women enrolled in the PMTCT programme in the Eastern Cape, South Africa. Methods This was a mixed-methods study involving 1709 parturient women in the Eastern Cape, South Africa. We conducted a multi-centre retrospective analysis of the mother-infant pair in the PMTCT electronic database in 2016. Semi-structured interviews of purposively selected parturient women with self-reported poor adherence (n = 177) were conducted to gain understanding of the main barriers to adherence. Binary logistic regression was used to determine the independent predictors of ART non-adherence. Results A high proportion (69.0%) of women reported perfect adherence. In the logistic regression analysis, after adjusting for confounding factors, marital status, cigarette smoking, alcohol use and non-disclosure to a family member were the independent predictors of non-adherence. Analysis of the qualitative data revealed that drug-related side-effects, being away from home, forgetfulness, non-disclosure, stigma and work-related demand were among the main reasons for non-adherence to ART. Conclusions Non-adherence to the antiretroviral therapy among pregnant women in this setting is associated with lifestyle behaviours, HIV-related stigma and ART side-effects. In order to eliminate mother-to-child transmission of HIV, clinicians need to screen for these factors at every antenatal clinic visit.

Abstract
Background As part of efforts to improve the prevention of mother-to-child transmission in Northern Uganda, we explored reasons for poor viral suppression among 122 pregnant and lactating women who were in care, received viral load tests, but had not achieved viral suppression and had more than 1000 copies/mL. Understanding the patient factors associated with low viral suppression was of interest to the Ministry of Health to guide the development of tools and interventions to achieve viral suppression for pregnant and lactating women newly initiating on ART as well as those on ART with unsuppressed viral load. Methods A facility-based cross-sectional and mixed methods study design was used, with retrospective medical record review. We assessed 122 HIV-positive mothers with known low viral suppression across 31 health facilities in Northern Uganda. Adjusted odds ratios were used to determine the covariates of adherence among HIV positive mothers using logistic regression. A study among health care providers shed further light on predictors of low viral suppression and a history of low early retention. This study was part of a larger national evaluation of the performance of integrated care services for mothers. Results Adherence defined as taking antiretroviral medications correctly everyday was low at 67.2%. The covariates of low adherence are: taking other medications in addition to ART, missed appointments in the past 6 months, experienced violence in the past 6 months, and faces obstacles to treatment. Mothers who were experiencing each of these covariates were less likely to adhere to treatment. These covariates were triangulated with perspectives of health providers as covariates of low adherence and included: long distances to health facility, missed appointments, running out of pills, sharing antiretroviral drugs, violence, and social lifestyles such as multiple sexual partners coupled with non-disclosure to partners. Inadequate counseling, stigma, and lack of client identity are the frontline factors accounting for the early loss of mothers from care. Conclusions Adherence of 67% was low for reliable viral suppression and accounts for the low viral suppression among HIV-positive mothers studied, in absence of any other factors. This study provided insights into the covariates for low adherence to ART and low viral load suppression; these covariates included taking other medications in addition to ART, missed appointments in the past 6 months, feels like giving up, doesn’t have someone with whom to share private concerns, experienced violence in the past 6 months, and faces obstacles to treatment and confirmed by health providers. To improve adherence, we recommend use of a screening tool to identify mothers with any of these covariates so that more intensive adherence support can be provided to these mothers.

Abstract
Success of antiretroviral therapy depends on adherence to effective treatment. We evaluated four adherence methods and their correlation with immunological and virologic response among women receiving PMTCT. Univariable and multivariable analyses were used to assess how adherence by pill count (n = 463), self-report (n = 463), MEMS (n = 129) and plasma drug level (n = 89) was associated with viral load suppression within a 6 months period. Longitudinal analysis was performed to determine the correlation of CD4 cell count with each measure of adherence. For all measures of adherence, sustained viral suppression was less likely for participants in the lowest category of adherence. Although CD4 cell count increased substantially over time, there was no significant association with adherence by the methods. Multiple strategies can be used successfully to monitor treatment adherence. Persons with ≥95% adherence by any method used in this study were more likely to have a favorable treatment outcome.

Abstract
Since 2012, the WHO recommends Option B+ for the prevention of mother-to-child transmission of HIV. This approach entails the initiation of lifelong antiretroviral therapy in all HIV-positive pregnant women, also implying protection during breastfeeding for 12 months or longer. Research on long-term adherence to Option B+ throughout breastfeeding is scarce to date. Therefore, we conducted a prospective observational cohort study in Fort Portal, Western Uganda, to assess adherence to Option B+ until 18 months postpartum. In 2013, we recruited 67 HIV-positive, Option B+ enrolled women six weeks after giving birth and scheduled them for follow-up study visits after six, twelve and 18 months. Two adherence measures, self-reported drug intake and amount of drug refill visits, were combined to define adherence, and were assessed together with feeding information at all study visits. At six months postpartum, 51% of the enrolled women were considered to be adherent. Until twelve and 18 months postpartum, adherence for the respective follow-up interval decreased to 19% and 20.5% respectively. No woman was completely adherent until 18 months. At the same time, 76.5% of the women breastfed for ≥12 months. Drug adherence was associated with younger age (p<0.01), lower travel costs (p = 0.02), and lower number of previous deliveries (p = 0.04). Long-term adherence to Option B+ seems to be challenging. Considering that in our cohort, prolonged breastfeeding until ≥12 months was widely applied while postpartum adherence until the end of breastfeeding was poor, a potential risk of postpartum vertical transmission needs to be taken seriously into account for Option B+ implementation.

Abstract
INTRODUCTION Timely, accurate and affordable testing algorithms at point-of-care are critical for early infant HIV diagnosis and initiation of antiretroviral therapy in the postpartum period. We aimed to assess the utility of HIV rapid tests for young, breast-fed HIV-exposed infants in resource limited, high HIV burden settings. MATERIALS AND METHODS We collected data on the performance of 2 commonly used rapid tests (Determine and Unigold) in Malawi between 2008 and 2012 or at the University of North Carolina between 2014 and 2015. For each 3-month interval between ages 3 and 18 months, we calculated the sensitivity, specificity, positive and negative predictive values of each test compared with the HIV DNA/RNA PCR gold standard. We also assessed the utility of each rapid test to diagnose incident HIV infection during the breastfeeding period. RESULTS Among 121 HIV-exposed infants who were negative at age 6 weeks, 21 (17.2%) became infected by 18 months. At 3 months of age, both rapid tests had minimal clinical value with specificity values of 7.0% [95% confidence interval (CI): 2.3-15.7] for Determine and 19.4% (95% CI: 11.1-30.5) for Unigold. Starting at age 6 and 9 months, the Unigold test could be used as a screening tool in the follow-up of HIV-exposed infants with specificity values of 83.7% (95% CI: 74.4-89.9) and 97.7% (95% CI: 94.6-99.7), respectively. Starting at age 12 months, the type of test became less important as both tests performed well in identifying HIV-free children, although both tests failed to detect some incident HIV infections. CONCLUSIONS Updated guidelines for the use of rapid tests in young HIV-exposed children that explicitly take type of test and infant age into account are urgently needed to ensure optimal care for the 1.5 million HIV-exposed infants born annually.

Abstract
Maternal adherence to antiretroviral therapy (ART) is a concern and monitoring adherence presents a significant challenge in low-resource settings. We investigated the association between self-reported adherence, measured using a simple three-item scale, and elevated viral load (VL) among HIV-infected pregnant and postpartum women on ART in Cape Town, South Africa. This is the first reported use of this scale in a non-English speaking setting and it achieved good psychometric characteristics (Cronbach α = 0.79). Among 452 women included in the analysis, only 12 % reported perfect adherence on the self-report scale, while 92 % had a VL <1000 copies/mL. Having a raised VL was consistently associated with lower median adherence scores and the area under the curve for the scale was 0.599, 0.656 and 0.642 using a VL cut-off of ≥50, ≥1000 and ≥10000 copies/mL, respectively. This simple self-report adherence scale shows potential as a first-stage adherence screener in this setting. Maternal adherence monitoring in low resource settings requires attention in the era of universal ART, and the value of this simple adherence scale in routine ART care settings warrants further investigation.

Abstract
BACKGROUND Antiretroviral (ARV) interventions are used to reduce HIV viral replication and prevent mother-to-child transmission. Viral suppression relies on adherence to ARVs. METHODS A 2-phase study was conducted using data from the Breastfeeding, Antiretrovirals, and Nutrition study. We included mothers randomized to 28 weeks of postpartum ARVs with ≥1 plasma or breastmilk specimen. All mothers who transmitted HIV to their infants from 2-28 weeks (n = 31) and 15% of mothers who did not (n = 232) were included. Adherence was measured by pill count [categorized as poor (0%-80%), partial (81%-98%), and near perfect (>98%)]. Associations between adherence and breastmilk RNA were assessed using mixed-effects models. Cox models were used to estimate associations between breastmilk RNA and HIV transmission. Using Monte Carlo simulation, we estimated the number of transmissions that would occur had everyone randomized to maternal ARVs been 90% and 100% adherent. RESULTS Partial or near perfect ARV adherence significantly reduced the odds of having detectable (≥40 copies/mL) breastmilk RNA, compared with poor adherence (Odds Ratio (OR) 0.23, 95% CI: 0.08 to 0.67; OR 0.36, 95% CI: 0.16 to 0.81, respectively). Detectable breastmilk RNA was associated with increased breastmilk transmission compared with undetectable breastmilk RNA (hazard ratio 3.8, 95% CI: 1.2 to 12.1). All transmitting mothers had ≥1 plasma viral load specimen >100 copies per milliliter. An estimated similar number of transmissions would occur with 90% adherence compared with 100%. CONCLUSIONS Helping patients adhere to ARVs throughout breastfeeding is important for realizing the full potential of recommended ARV interventions to prevent mother-to-child HIV transmission. Maintaining plasma viral load <100 copies per milliliter may prevent breastmilk transmission.

Abstract
BACKGROUND Rates of maternal mortality and morbidity vary markedly, both between and within countries. Documenting these variations, in a very unequal society like South Africa, provides useful information to direct initiatives to improve services. The study describes inequalities over time in access to maternal health services in South Africa, and identifies differences in maternal health outcomes between population groups and across geographical areas. METHODS Data were analysed from serial population-level household surveys that applied multistage-stratified sampling. Access to maternal health services and health outcomes in 2008 (n = 1121) were compared with those in 2012 (n = 1648). Differences between socio-economic quartiles were quantified using the relative (RII) and slope (SII) index of inequality, based on survey weights. RESULTS High levels of inequalities were noted in most measures of service access in both 2008 and 2012. Inequalities between socio-economic quartiles worsened over time in antenatal clinic attendance, with overall coverage falling from 97.0 to 90.2 %. Nationally, skilled birth attendance remained about 95 %, with persistent high inequalities (SII = 0.11, RII = 1.12 in 2012). In 2012, having a doctor present at childbirth was higher than in 2008 (34.4 % versus 27.8 %), but inequalities worsened. Countrywide, levels of planned pregnancy declined from 44.6 % in 2008 to 34.7 % in 2012. The RII and SII rose over this period and in 2012, only 22.4 % of the poorest quartile had a planned pregnancy. HIV testing increased substantially by 2012, though remains low in groups with a high HIV prevalence, such as women in rural formal areas, and from Gauteng and Mpumalanga provinces. Marked deficiencies in service access were noted in the Eastern Cape ad North West provinces. CONCLUSIONS Though some population-level improvements occurred in access to services, inequalities generally worsened. Low levels of planned pregnancy, antenatal clinic access and having a doctor present at childbirth among poor women are of most concern. Policy makers should carefully balance efforts to increase service access nationally, against the need for programs targeting underserved populations.

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.

Abstract
OBJECTIVES Maternal HIV viral load (VL) drives mother-to-child HIV transmission (MTCT) risk but there are few data from sub-Saharan Africa, where most MTCT occurs. We investigated VL changes during pregnancy and MTCT following antiretroviral therapy (ART) initiation in Cape Town, South Africa. METHODS We conducted a prospective study of HIV-infected women initiating ART within routine antenatal services in a primary care setting. VL measurements were taken before ART initiation and up to three more times within 7 days postpartum. Analyses examined VL changes over time, viral suppression (VS) at delivery, and early MTCT based on polymerase chain reaction (PCR) testing up to 8 weeks of age. RESULTS A total of 620 ART-eligible HIV-infected pregnant women initiated ART, with 2425 VL measurements by delivery (median gestation at initiation, 20 weeks; median pre-ART VL, 4.0 log10 HIV-1 RNA copies/mL; median time on ART before delivery, 118 days). At delivery, 91% and 73% of women had VL ≤ 1000 and ≤ 50 copies/mL, respectively. VS was strongly predicted by time on therapy and pre-ART VL. The risk of early MTCT was strongly associated with delivery VL, with risks of 0.25, 2.0 and 8.5% among women with VL < 50, 50-1000 and > 1000 copies/mL at delivery, respectively (P < 0.001). CONCLUSIONS High rates of VS at delivery and low rates of MTCT can be achieved in a routine care setting in sub-Saharan Africa, indicating the effectiveness of currently recommended ART regimens. Women initiating ART late in pregnancy and with high VL appear substantially less likely to achieve VS and require targeted research and programmatic attention.

Abstract
BACKGROUND This article assessed maternal and neonatal outcomes amongst users of prevention of mother-to-child transmission (PMTCT) of HIV services in Addis Ababa, Ethiopia. OBJECTIVES The study aimed to assess the health outcomes (antiretroviral prophylaxis versus antiretroviral treatment, CD4 counts, World Health Organization (WHO) stages of illness, other illnesses) of women who had used these services, as well as the HIV status of their babies and the infant feeding method adopted. METHODS A quantitative, cross sectional, retrospective cohort design was used. Document reviews were conducted with a sample of 384 mother-infant pairs (out of a population of 796) who had used PMTCT services. RESULTS All respondents were using prophylactic antiretrovirals or antiretroviral therapy, but some were on the wrong treatment based on their CD4 counts. The CD4 counts increased four times more for women on antiretroviral treatment than for those on prophylactic antiretrovirals. The WHO's stages of HIV illness did not improve but deteriorated in some cases, and 52 other illnesses were recorded. Out of the 384 infants, 6.0% (n = 23) were HIV-positive. Most respondents opted for exclusive breast feeding but some used mixed feeding during the first six months of their infants' lives, despite having received health education related to infant feeding options. CONCLUSION The respondents' improved CD4 counts were inadequate to improve their World Health Organization stages of HIV illness. Some babies received mixed feeding during the first six months of their lives and 6% of the babies were HIV-positive despite their mothers' utilisation of PMTCT services.

Abstract
The often cited need to achieve ≥95% (nearly perfect) adherence to antiretroviral therapy (ART) for successful virologic outcomes in HIV may present a barrier to initiation of therapy in the early stages of HIV. This meta-analysis synthesized 43 studies (27,905 participants) performed across >26 countries, to determine the relationship between cut-off point for optimal adherence to ART and virologic outcomes. Meta-analysis was performed using a random-effect model to calculate pooled odds ratios with corresponding 95% confidence intervals. The mean rate of patients reporting optimal adherence was 63.4%. Compared with suboptimal adherence, optimal adherence was associated with a lower risk of virologic failure (0.34; 95% CI: 0.26-0.44). There were no significant differences in the pooled odds ratios among different optimal adherence thresholds (≥98-100%, ≥95%, ≥80-90%). Study design (randomized controlled trial vs observational study) (regression coefficient 0.74, 95% CI: 0.04-1.43, P < 0.05) and study region (developing vs developed countries; regression coefficient 0.56, 95% CI: 0.01-1.12, P < 0.05) remained as independent predictors of between-study heterogeneity, with more patients with optimal adherence from developing countries or randomized controlled trials experiencing virologic failure. The threshold for optimal adherence to achieve better virologic outcomes appears to be wider than the commonly used cut-off point (≥95% adherence). The cut-off point for optimal adherence could be redefined to a slightly lower level to encourage the prescribing ART at an early stage of HIV infection.

Abstract
Since 2012, lifelong antiretroviral therapy for all HIV-positive pregnant women ("Option B+") is recommended by WHO for the prevention of mother-to-child transmission of HIV (PMTCT). Many sub-Saharan African countries have since introduced this regimen, but to date, longer-term outcome evaluations are scarce. We conducted an observational study in Fort Portal Municipality, Uganda, to describe uptake and adherence of Option B+ during pregnancy. HIV-positive women approaching antenatal care (ANC) services in two hospitals were enrolled and followed-up at monthly routine ANC visits until delivery. At each visit, next to sociodemographic and clinical data, we assessed drug adherence through pill counts. In total, 124 HIV-positive pregnant women were enrolled in our study; from these, 80.8% had not been aware of their positive serostatus before. Forty-five PMTCT clients (36.3%) never returned to ANC after their first visit. Protective factors (p < 0.05) for immediate loss to care included previous HIV status knowledge, status disclosure before or at first ANC visit, and tertiary education. Among those clients starting Option B+, the median adherence during pregnancy was 95.7% pill intake. Rather low adherence (<80%) was observed in 21.1% of clients, while more than half achieved an adherence level of ≥95%, with 40.8% of all clients being 100% adherent. The cohort's median adherence remained stable throughout the course of pregnancy. Healthcare providers should place high emphasis on individual PMTCT counseling at first ANC encounter, and pay special attention to those women previously unaware of their HIV status. However, after initial uptake, high adherence seems to be feasible for Option B+.

Abstract
BACKGROUND We assessed HIV RNA suppression, resistance, and CD4 T-cell count 12 months postpartum among pregnant women retained in care in an observational cohort study. METHODS We prospectively followed two groups of HIV-infected pregnant women--with or without tuberculosis--recruited from prenatal clinics in South Africa. Women who received antiretroviral therapy during pregnancy and reported being on therapy 12 months postpartum were included. Serum samples from women with HIV viremia 12 months postpartum were tested for drug resistance. RESULTS Of 103 women in the study, median age and CD4 T-cell count at enrollment were 29 years [interquartile range (IQR): 26-32] and 317 cells per cubic millimeter (IQR: 218-385), respectively; 43 (42%) had tuberculosis at baseline. During pregnancy, 87% of the women achieved an HIV RNA <400 copies per milliliter compared with 71% at 12 months postpartum (P < 0.001). Factors independently associated with an HIV RNA <400 copies per milliliter at 12 months were age ≥ 30 years, detectable plasma efavirenz concentration, and HIV RNA <400 copies per milliliter while pregnant; there was a trend toward both a detectable viral load and peripartum depression. HIV drug resistance results were available from 25 women, and 12 (48%) had major drug resistance mutations. CD4 T-cell count declined a median of 13 cells per cubic millimeter (IQR: -66 to 140) from delivery to 12 months in women with viremia at 12 months. CONCLUSIONS Success with maintaining virologic control declined postpartum among HIV-infected women who remained in care and on antiretroviral therapy, and CD4 T-cell count decline and drug resistance were common.

Abstract
Antiretroviral adherence in the postpartum period is crucial for maternal health and decreasing the risk of mother-to-child HIV transmission and transmission to sexual partners. Self-reported antiretroviral adherence was examined between 6- to 12-weeks and 30 months postpartum among 270 HIV-infected women enrolled in a prospective cohort study from 2008 to 2010 at multiple sites in Latin America. Adherence data were collected at each study visit to quantify the proportion of prescribed antiretrovirals taken during the previous three days, assess the timing of the last missed dose, and identify predictors of adherence. Mean adherence rates were 89.5% at 6-12 weeks and 92.4% at 30 months; the proportions with perfect adherence were 80.3% and 83.6%, respectively. The overall trend for perfect adherence was not significant (p = 0.71). In adjusted regression modelling, younger age was associated with an increased probability of non-perfect adherence at 18 and 24 months postpartum. Other factors associated with increased probability of non-perfect adherence were higher parity, current use of alcohol and tobacco, and more advanced HIV disease. Women with perfect adherence had lower viral loads. Interventions for alcohol and tobacco use cessation, and support for young women and those with advanced HIV disease should be considered to improve postpartum adherence.

Abstract
BACKGROUND A high delivery maternal plasma HIV-1 RNA level (viral load [VL]) is a risk factor for mother-to-child transmission and poor maternal health. OBJECTIVE To identify factors associated with detectable VL at delivery despite initiation of highly active antiretroviral therapy (HAART) during pregnancy. DESIGN Multicenter observational study. (ClinicalTrial.gov: NCT00028145). SETTING 67 U.S. AIDS clinical research sites. PATIENTS Pregnant women with HIV who initiated HAART during pregnancy. MEASUREMENTS Descriptive summaries and associations among sociodemographic, HIV disease, and treatment characteristics; pregnancy-related risk factors; and detectable VL (>400 copies/mL) at delivery. RESULTS Between 2002 and 2011, 671 women met inclusion criteria and 13.1% had detectable VL at delivery. Factors associated with detectable VL included multiparity (16.4% vs. 8.0% nulliparity; P = 0.002), black ethnicity (17.6% vs. 6.6% Hispanic and 6.6% white; P < 0.001), 11th grade education or less (17.6% vs. 12.1% had a high school diploma; P = 0.013), initiation of HAART in the third trimester (23.9% vs. 12.3% and 8.6% in the second and trimesters, respectively; P = 0.003), having an HIV diagnosis before the current pregnancy (16.1% vs. 11.0% during the current pregnancy; P = 0.051), and having the first prenatal visit in the third trimester (33.3% vs. 14.3% and 10.5% in the second and third trimesters, respectively; P = 0.002). Women who had treatment interruptions or reported poor medication adherence were more likely to have detectable VL at delivery. LIMITATION Data on many covariates were incomplete because women entered the study at varying times during pregnancy. CONCLUSION A total of 13.1% of women who initiated HAART during pregnancy had detectable VL at delivery. The timing of HAART initiation and prenatal care, along with medication adherence during pregnancy, were associated with detectable VL at delivery. Social factors, including ethnicity and education, may help identify women who could benefit from focused efforts to promote early HAART initiation and adherence.

Vet Microbiol 2015; 176:50-60.

Abstract
Multi-cat household animals displayed 63% mortality rate. Lymphoma was the most common cause of death. The CD4:CD8 ratio failed to distinguish cats classified as healthy and not healthy. FIV load failed to distinguish cats classified as healthy and not healthy. Management and housing conditions impact on the progression of FIV infection.
Despite over 25 years of feline immunodeficiency virus (FIV) research, relatively little is known about the longitudinal course of FIV infection following natural infection. In contrast to published reports of experimental infections using lethal strains of the virus, clinical signs of naturally acquired FIV infection can be mild or inapparent, rather than life-threatening. In this prospective, longitudinal controlled study, based in Chicago, IL (n = 17) and Memphis, TN (n = 27), we investigated two cohorts of privately owned, naturally infected cats kept under different housing conditions. Cats in the Chicago cohort (Group 1) were kept in households of ≤2 cats, while the Memphis cohort (Group 2) comprised part of a large multi-cat household of over 60 cats kept indoors only, with unrestricted access to one another. The majority of cats from Group 1 did not display clinical signs consistent with immunodeficiency during the 22-month observation period. In contrast, the outcome of infection in Group 2 was dramatically different; 17/27 (63%) of cats lost a median of 51.3% of their bodyweight (P < 0.0005) and died during the study period, with lymphoma being the most common cause of mortality. Although the decrease in CD4+ T cell count between enrolment and terminal disease was significant (P = 0.0017), the CD4:CD8 ratio at the time of enrolment did not reliably distinguish FIV-positive cats classified as ‘healthy’ and ‘not healthy’ at either cohort. FIV load at enrolment was significantly lower in Group 1 than in Group 2 (P < 0.0001), but there were no significant differences at enrolment between healthy and not healthy cats at either group. In conclusion, the results of this study suggest that management and housing conditions impact on disease progression and survival times of FIV-positive cats.

Abstract
OBJECTIVES To identify factors associated with detectable viral load and the emergence of drug resistance in a cohort of HIV-infected pregnant women in Malawi receiving antiretroviral combination regimens for the prevention of mother-to-infant transmission. METHODS The study included 260 treatment-naive women who had received a three-drug nevirapine-based regimen from week 25 of gestational age until 6 months after delivery. HIV RNA was determined at month 6 and drug resistance was assessed if viral load was >50 copies/mL. Attendance at the scheduled follow-up visits was used as an indirect measure of treatment adherence. RESULTS The rate of detectable HIV RNA at 6 months was 9.6% (25/260). The only significant predictor of this occurrence was the presence of ≥1 missed visit during follow-up (P = 0.012). Resistance was assessed in 19 of these women: 7 (37%) had a wild-type virus and the other 12 (63%) had resistance-associated mutations (nucleoside reverse transcriptase inhibitor, 7/12; non-nucleoside reverse transcriptase inhibitor, 11/12). Three of 12 cases (25%) in which mutations were detected had a viral load <1000 copies/mL. The emergence of resistance was not correlated with the presence of baseline mutations in either plasma or archived DNA. CONCLUSIONS In this cohort of women, detectable HIV RNA 6 months post-partum was infrequent and associated with low adherence to the treatment programme. Mutations were present in 63% of the women with detectable viral load at 6 months who had samples available for resistance testing. The impact of resistance on treatment re-initiation in women discontinuing drugs after the risk of transmission has ceased can be limited.

Abstract
BACKGROUND The Zambian Defence Force (ZDF) is working to improve the quality of services to prevent mother-to-child transmission of HIV (PMTCT) at its health facilities. This study evaluates the impact of an intervention that included provider training, supportive supervision, detailed performance standards, repeated assessments of service quality, and task shifting of group education to lay workers. METHODS Four ZDF facilities implementing the intervention were matched with four comparison sites. Assessors visited the sites before and after the intervention and completed checklists while observing 387 antenatal care (ANC) consultations and 41 group education sessions. A checklist was used to observe facilities' infrastructure and support systems. Bivariate and multivariate analyses were conducted of findings on provider performance during consultations. RESULTS Among 137 women observed during their initial ANC visit, 52% came during the first 20 weeks of pregnancy, but 19% waited until the 28th week or later. Overall scores for providers' PMTCT skills rose from 58% at baseline to 73% at endline (p=0.003) at intervention sites, but remained stable at 52% at comparison sites. Especially large gains were seen at intervention sites in family planning counseling (34% to 75%, p=0.026), HIV testing during return visits (13% to 48%, p=0.034), and HIV/AIDS management during visits that did not include an HIV test (1% to 34%, p=0.004). Overall scores for providers' ANC skills rose from 67% to 74% at intervention sites, but declined from 65% to 59% at comparison sites; neither change was significant in the multivariate analysis. Overall scores for group education rose from 87% to 91% at intervention sites and declined from 78% to 57% at comparison sites. The overall facility readiness score rose from 73% to 88% at intervention sites and from 75% to 82% at comparison sites. CONCLUSIONS These findings are relevant to civilian as well as military health systems in Zambia because the two are closely coordinated. Lessons learned include: the ability of detailed performance standards to draw attention to and strengthen areas of weakness; the benefits of training lay workers to take over non-clinical PMTCT tasks; and the need to encourage pregnant women to seek ANC early.

Abstract
BACKGROUND South Africa is increasingly focused on reducing maternal mortality. Documenting variation in access to maternal health services across one of the most inequitable nations could assist in re-direction of resources. METHODS Analysis draws on a population-based household survey that used multistage-stratified sampling. Women, who in the past two years were pregnant (1113) or had a child (1304), completed questionnaires and HIV testing. Distribution of access to maternal health services and health status across socio-economic, education and other population groups was assessed using weighted data. FINDINGS Poorest women had near universal antenatal care coverage (ANC), but only 39.6% attended before 20 weeks gestation; this figure was 2.7-fold higher in the wealthiest quartile (95%CI adjusted odds ratio = 1.2-6.1). Women in rural-formal areas had lowest ANC coverage (89.7%), percentage completing four ANC visits (79.7%) and only 84.0% were offered HIV testing. Testing levels were highest among the poorest quartile (90.1% in past two years), but 10% of women above 40 or with low education had never tested. Skilled birth attendant coverage (overall 95.3%) was lowest in the poorest quartile (91.4%) and rural formal areas (85.6%). Around two thirds of the wealthiest quartile, of white and of formally-employed women had a doctor at childbirth, 11-fold higher than the poorest quartile. Overall, only 44.4% of pregnancies were planned, 31.7% of HIV-infected women and 68.1% of the wealthiest quartile. Self-reported health status also declined considerably with each drop in quartile, education level or age group. CONCLUSIONS Aside from early ANC attendance and deficiencies in care in rural-formal areas, inequalities in utilisation of services were mostly small, with some measures even highest among the poorest. Considerably larger differences were noted in maternal health status across population groups. This may reflect differences between these groups in quality of care received, HIV infection and in social determinants of health.
