Abstract
Antiretroviral therapy (ART) adherence is crucial for health outcomes of people living with HIV (PLHIV), influenced by a complex interplay of individual, community, and household factors. This article focuses on the influence of household factors, as well as individual and community factors, on ART adherence among PLHIV in Cape Town who have recently initiated ART. Baseline data for a cluster-randomized controlled trial were collected from 316 PLHIV in 12 districts in Cape Town between 6th May 2021 and 22nd May 2022. Zero-inflated Poisson models, with cluster-adjusted standard errors, were used to analyse the association between individual, household, and community factors and ART adherence measures. At the household-level, household support was associated with both better self-rated adherence (exp(β) = 0.81, z = - 4.68, p < 0.001) and fewer days when pills were missed (exp(β) = 0.65, z = - 2.92, p = 0.003). Psychological violence (exp(β) = 1.37, z = 1.97, p = 0.05) and higher household asset scores (exp(β) = 1.29, z = - 2.83, p = 0.05) were weakly associated with poorer ART adherence. At the individual-level, male gender (exp(β) = 1.37, z = 3.95, p < 0.001) and reinitiating ART (exp(β) = 1.35, z = 3.64, p < 0.001) were associated with worse self-rated ART adherence; higher education levels (exp(β) = 0.30 times, z = - 3.75, p < 0.001) and better HIV knowledge (exp(β) = 0.28, z = - 2.83, p = 0.005) were associated with fewer days where pills were missed. At the community-level, community stigma was associated with worse self-rated ART adherence (exp(β) = 1.24, z = 3.01, p = 0.003). When designing interventions to improve ART adherence, household, individual and community factors should all be considered, particularly in addressing gender-based disparities, reducing stigma, tackling violence, and enhancing household support.Clinical Trial Number: Pan African Clinical Trial Registry, PACTR201906476052236.

Abstract
Children who are HIV-exposed and uninfected (CHEU) are at increased risk for poor growth, health, and development compared to children who are HIV-unexposed and uninfected. To support families with CHEU, we assessed the acceptability of engaging family members to support women living with HIV (WLWH) with exclusive breastfeeding (EBF) and antiretroviral therapy (ART) adherence and to engage in responsive infant caregiving. We conducted trials of improved practices, a consultative research approach, that follows participants over time as they try recommended behaviors. We enrolled postpartum women in Lusaka, Zambia, who identified home supporters. At visit 1, WLWH were interviewed about current practices. At visit 2, WLWH and home supporters received tailored EBF, responsive care, and ART adherence counseling. At visit 3, WLWH and home supporters were interviewed about their experiences trying recommended practices for 2-3 weeks. Interview transcripts were analyzed thematically. Participants included 23 WLWH, 15 male partners, and 8 female family members. WLWH reported several barriers to EBF. The most common were fear of HIV transmission via breastfeeding-despite high ART adherence-and insufficient breastmilk. After counseling, WLWH reported less fear of HIV transmission and improved breastfeeding practices. Home supporters reported providing WLWH increased support for EBF and ART adherence and practicing responsive caregiving. Both male and female home supporters appreciated being included in counseling and more involved in caregiving, and WLWH valued the increased support. Families with CHEU need focused support. Tailored counseling and family support for WLWH show promise for improving EBF, responsive caregiving, and ART adherence.

Abstract
ABSTRACTAdherence to antiretroviral therapy (ART) remains sub-optimal among pregnant and postpartum women with HIV (PPWH) in high HIV prevalence low resource settings with few effective behavioral interventions. A large body of qualitative literature has established general barriers and facilitators to ART adherence in PPWH at various levels (individual, interpersonal, structural). However, research exploring the underlying behavioral mechanisms of ART adherence in PPWH with objectively verified adherence biomarkers is extremely limited. We conducted 24 in-depth interviews with postpartum women in western Kenya who had linked ART drug concentrations obtained from three dried blood spot samples across the peripartum period. Among PPWH with a low drug concentration (n = 13) compared to those with continuously high drug concentrations (n = 11), distinct themes emerged related to HIV status disclosure, social support, interactions with the health system, and health beliefs. By combining ART biomarkers with patient reported challenges, there is the potential for real-time interventions to support sustained ART adherence among PPWH and improve maternal and infant health outcomes.

Understanding the uptake and determinants of prevention of mother-to-child transmission of HIV services in East Africa: Mixed methods systematic review and meta-analysis. PLoS One 2024; 19:e0300606. [PMID: 38635647 PMCID: PMC11025786 DOI: 10.1371/journal.pone.0300606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 02/28/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND Prevention of mother-to-child transmission (PMTCT) of HIV service is conceptualized as a series of cascades that begins with all pregnant women and ends with the detection of a final HIV status in HIV-exposed infants (HEIs). A low rate of cascade completion by mothers' results in an increased risk of HIV transmission to their infants. Therefore, this review aimed to understand the uptake and determinants of key PMTCT services cascades in East Africa. METHODS We searched CINAHL, EMBASE, MEDLINE, Scopus, and AIM databases using a predetermined search strategy to identify studies published from January 2012 through to March 2022 on the uptake and determinants of PMTCT of HIV services. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool. A random-effects model was used to obtain pooled estimates of (i) maternal HIV testing (ii) maternal ART initiation, (iii) infant ARV prophylaxis and (iv) early infant diagnosis (EID). Factors from quantitative studies were reviewed using a coding template based on the domains of the Andersen model (i.e., environmental, predisposing, enabling and need factors) and qualitative studies were reviewed using a thematic synthesis approach. RESULTS The searches yielded 2231 articles and we systematically reduced to 52 included studies. Forty quantitative, eight qualitative, and four mixed methods papers were located containing evidence on the uptake and determinants of PMTCT services. The pooled proportions of maternal HIV test and ART uptake in East Africa were 82.6% (95% CI: 75.6-88.0%) and 88.3% (95% CI: 78.5-93.9%). Similarly, the pooled estimates of infant ARV prophylaxis and EID uptake were 84.9% (95% CI: 80.7-88.3%) and 68.7% (95% CI: 57.6-78.0) respectively. Key factors identified were the place of residence, stigma, the age of women, the educational status of both parents, marital status, socioeconomic status, Knowledge about HIV/PMTCT, access to healthcare facilities, attitudes/perceived benefits towards PMTCT services, prior use of maternal and child health (MCH) services, and healthcare-related factors like resource scarcity and insufficient follow-up supervision. CONCLUSION Most of the identified factors were modifiable and should be considered when formulating policies and planning interventions. Hence, promoting women's education and economic empowerment, strengthening staff supervision, improving access to and integration with MCH services, and actively involving the community to reduce stigma are suggested. Engaging community health workers and expert mothers can also help to share the workload of healthcare providers because of the human resource shortage.

Abstract
BACKGROUND Daily oral pre-exposure prophylaxis (PrEP) can reduce HIV incidence in pregnant and breastfeeding women, but adherence is essential. METHODS We conducted a pilot randomized trial to evaluate an intervention package to enhance antenatal and postnatal PrEP use in Lilongwe, Malawi. The intervention was based on patient-centered counseling adapted from previous PrEP studies, with the option of a participant-selected adherence supporter. Participants were locally eligible for PrEP and randomized 1:1 to intervention or standard counseling (ie, control) and followed for 6 months. Participants received the intervention package or standard counseling at enrollment, 1, 3, and 6 months. Adherence was measured through plasma and intracellular tenofovir concentrations and scored using a published algorithm. Our primary outcome was retention in care with concentrations consistent with 4-7 doses/week. RESULTS From June to November 2020, we enrolled 200 pregnant women with the median gestational age of 26 (interquartile range: 19-33) weeks. Study retention was high at 3 months (89.5%) and 6 months (85.5%). By contrast, across the 2 time points, 32.8% of participants retained in the study had adherence scores consistent with 2-5 doses/week while 10.3% had scores consistent with daily dosing. For the composite primary end point, no substantial differences were observed between the intervention and control groups at 3 months (28.3% vs. 29.0%, probability difference: -0.7%, 95% confidence interval: -13.3%, 11.8%) or at 6 months (22.0% vs. 26.3%, probability difference: -4.3%, 95% confidence interval: -16.1%, 7.6%). CONCLUSIONS In this randomized trial of PrEP adherence support, retention was high, but less than one-third of participants had pharmacologically confirmed adherence of ≥4 doses/week. Future research should focus on antenatal and postnatal HIV prevention needs and their alignment across the PrEP continuum, including uptake, persistence, and adherence.

Facilitators and barriers to infant post-natal HIV prophylaxis, a qualitative sub-study of the PROMISE-EPI trial in Lusaka, Zambia. Front Public Health 2023; 11:1242904. [PMID: 37663847 PMCID: PMC10469758 DOI: 10.3389/fpubh.2023.1242904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 08/07/2023] [Indexed: 09/05/2023] Open
Abstract
Background Infant post-natal prophylaxis (PNP) is used to prevent HIV transmission through breastfeeding. The WHO edited recommendations but so far there is no consensus on the duration of prophylaxis and the type of drug used depends on national guidelines. In Zambia, the national recommendations include a three-drug prophylaxis, composed of a dispersible combined tablet of zidovudine (AZT) and lamivudine (3TC) and an oral suspension of nevirapine (NVP) for 12 weeks or until the mother's viral load is <1,000 cp/mL. The PROMISE-EPI study, modified the PNP regimen to lamivudine only, initiated at 6 weeks and continued until 12 months to all HIV exposed uninfected infants of virally unsuppressed mothers. Our aim in this analysis was to identify barriers and facilitators to this extended PNP, the keystone toward an effective prevention. Methods Individual interviews and focus group discussion (FGD) were conducted with PROMISE-EPI participants who had received prophylaxis for their children from the national program up to 6 weeks and then lamivudine oral solution in PROMISE-EPI study. Health care providers and PROMISE-EPI staff were also interviewed. Sessions were recorded, transcribed verbatim and translated from local languages into English. An initial code-book was designed and then adapted on the basis of the emerging themes, to allow a descriptive thematic analysis. Results More barriers to PNP adherence were identified with triple drug prophylaxis than with lamivudine. These barriers were related to the formulation and bitter taste of AZT/3TC tablets. The ready to use formulation and sweet taste of lamivudine syrup were appreciated by mothers. Extended PNP proposed in the PROMISE-EPI study was globally well accepted and strategies were found to increase adherence. Adherence to lamivudine appeared to be better than the mothers' adherence to their own antiretroviral therapy. Conclusion Accompanying mothers living with HIV and giving them the choice of the PNP to prevent transmission via breastfeeding (type of PNP regimen and extended PNP in non-adherent mothers), may be one of the keys to reducing the burden of pediatric HIV acquisition in low and middle income countries.
