RESUMO

This qualitative study reports on female sex workers' (FSWs) perceptions of the quality of antiretroviral therapy (ART) services they received as part of a community-based ART distribution intervention compared to services received by FSWs in the standard of care (SOC) arm. In-depth interviews were conducted with 24 participants to explore their perceptions of the quality of ART services. Data was analyzed using a quality-of-care framework that included but was not limited to, domains of accessibility, effective organization of care, package of services, and patient-centered care. Overall, FSWs in the intervention arm reported community-based ART services to be highly accessible, organized, and effective, and they highly valued the patient-centered care and high level of privacy. Community-based ART programs for FSWs can have high quality-of-care, which can have a positive effect on HIV treatment outcomes for FSWs.

RESUMO

BACKGROUND: To assess the adherence to option B + antiretroviral therapy (ART) and associated factors in pregnant and breastfeeding women in Sub-Saharan Africa (SSA). METHODS: We conducted a comprehensive search from 01st January 2012 to 03rd October 2022, across four databases: PubMed, Scopus, Proquest Central, and Index Medicus Africain, to identify studies focused on pregnant and/or breastfeeding women living with HIV and receiving option B+ ART in SSA. Studies reporting adherence data were included in the meta-analysis. Were excluded studies published before 01st January 2012, grey literature, systematic reviews, and meta-analysis studies. Articles selection and data extraction were performed independently by two reviewers. We evaluated pooled adherence and pooled association between various factors and adherence using a random-effects model. RESULTS: Overall, 42 studies involving 15,158 participants across 15 countries contributed to the meta-analysis. The overall pooled adherence was 72.3% (95% CI: 68.2-76.1%). Having high education level (pooled odds ratio (OR): 2.25; 95% CI: 1.57-3.21), living in urban area (pooled OR: 1.75; 95% CI: 1.10-2.81), disclosing status to a family/partner (pooled OR: 1.74; 95% CI: 1.27-2.40), having a support system (pooled OR: 3.19; 95% CI: 1.89-5.36), receiving counseling (pooled OR: 3.97; 95% CI: 2.96-5.34), initiating ART at early clinical HIV stage (pooled OR: 2.22; 95% CI: 1.08-4.56), and having good knowledge on PMTCT/HIV (pooled OR: 2.71; 95% CI: 1.40-5.25) were factors significantly associated with adherence to option B + ART. CONCLUSIONS: Despite the implementation of option B+ ART, the level of adherence among pregnant and breastfeeding women in SSA falls short of meeting the critical thresholds for viral load suppression as outlined in the 95-95-95 objectives set for 2025. These objectives are integral for achieving HIV elimination, and in turn, preventing HIV mother-to-child transmission. To bridge this gap, urgent tailored interventions based on individual and structural factors are essential to enhance adherence within these subgroups of women. This targeted approach is crucial in striving towards the HIV elimination target in SSA.

RESUMO

Women with HIV (WWH) face increased difficulties maintaining adherence to antiretroviral therapy (ART) due to a variety of demographic and psychosocial factors. To navigate the complexities of ART regimens, use of strategies to maintain adherence is recommended. Research in this area, however, has largely focused on adherence interventions, and few studies have examined self-reported preferences for adherence strategies. The purpose and objectives of this study were to explore the use of ART self-management strategies among a diverse sample of WWH, examine demographic and psychosocial differences in strategy use, and assess the association between strategies and ART adherence. The current study presents secondary data of 560 WWH enrolled in the Miami-Dade County Ryan White Program. Participants responded to questionnaire items assessing demographic and psychosocial characteristics, use of adherence strategies, and ART adherence during the past month. Principal component analysis identified four categories among the individual strategies and multivariable binomial logistic regression assessed adherence while controlling for individual-level factors. The majority of WWH reported optimal ART adherence, and nearly all used multiple individual strategies. The number of individual strategies used and preferences for strategy types were associated with various demographic and psychosocial characteristics. Adjusting for demographic and psychosocial characteristics, optimal ART adherence during the past month was associated with the use of four or more individual strategies. When conducting regular assessments of adherence, it may be beneficial to also assess use of adherence strategies and to discuss with WWH how using multiple strategies contributes to better adherence.

RESUMO

Antiretroviral medications have substantially improved life expectancy for people with HIV. These medications are also highly effective in preventing HIV acquisition in people who do not have HIV, a strategy known as HIV preexposure prophylaxis (PrEP). Despite these advances, some life and disability insurers continue to deny or limit coverage for people with HIV, and some have even refused to cover people who are using PrEP to protect themselves. These policies unfairly deny people with HIV, PrEP users, and their families the peace of mind and financial protection that can come with life and disability insurance coverage. This article summarizes the current evidence on HIV treatment and prevention, arguing that underwriting decisions by life and disability insurers should not be made based on HIV status or use of PrEP.

RESUMO

Over the past few decades, the life expectancy of people living with HIV has markedly improved due to the advances in HIV diagnosis, linkage to care, and treatment. However, with these advances, a new set of challenges has emerged that must be addressed to ensure the long-term well-being of people living with HIV. In this article, as part of a wider journal supplement, we explore the unmet needs and challenges across the HIV continuum of care and re-define what long-term success looks like to support the healthy ageing of all people affected by HIV.

RESUMO

PURPOSE OF REVIEW: In the absence of a prophylactic/therapeutic vaccine or cure, the most amazing achievement in the battle against HIV was the discovery of effective, well-tolerated combination antiretroviral therapy (cART). The primary research question remains whether PLWH on prolonged successful therapy has accelerated, premature, or accentuated biological aging. In this review, we discuss the current understanding of the immunometabolic profile in PLWH, potentially associated with biological aging, and a better understanding of the mechanisms and temporal dynamics of biological aging in PLWH. RECENT FINDINGS: Biological aging, defined by the epigenetic alterations analyzed by the DNA methylation pattern, has been reported in PLWH with cART that points towards epigenetic age acceleration. The hastened development of specific clinical geriatric syndromes like cardiovascular diseases, metabolic syndrome, cancers, liver diseases, neurocognitive diseases, persistent low-grade inflammation, and a shift toward glutamate metabolism in PLWH may potentiate a metabolic profile at-risk for accelerated aging.

RESUMO

Structural inequities have led to HIV disparities, including relatively low antiretroviral therapy adherence and viral suppression rates among Black Americans living with HIV. We conducted a randomized controlled trial of Rise, a community-based culturally congruent adherence intervention, from January 2018 to December 2021 with 166 (85 intervention, 81 control) Black adults living with HIV in Los Angeles County, California [M (SD) = 49.0 (12.2) years-old; 76% male]. The intervention included one-on-one counseling sessions using basic Motivational Interviewing style to problem solve about adherence, as well as referrals to address unmet needs for social determinants of health (e.g., housing services, food assistance). Assessments included electronically monitored adherence; HIV viral load; and baseline, 7-month follow-up, and 13-month follow-up surveys of sociodemographic characteristics, HIV stigma, medical mistrust, and HIV-serostatus disclosure. Repeated-measures intention-to-treat regressions indicated that Rise led to significantly (two-fold) higher adherence likelihood, lower HIV stigmatizing beliefs, and reduced HIV-related medical mistrust. Effects on HIV viral suppression, internalized stigma, and disclosure were non-significant. Moreover, Rise was cost-effective based on established standards: The estimated cost per person to reach optimal adherence was $335 per 10% increase in adherence. Interventions like Rise, that are culturally tailored to the needs of Black populations, may be optimal for Black Americans living with HIV (ClinicalTrials.gov #NCT03331978).


RESUMEN: Las desigualdades estructurales han dado lugar a disparidades relacionadas con el VIH, incluyendo la relativamente baja adherencia a la terapia antirretroviral (TAR) y las tasas de supresión viral entre los afroamericanos que viven con el VIH. Conducimos una prueba controlada aleatoria de Rise, una intervención de adherencia culturalmente congruente basada en la comunidad, desde Enero de 2018 hasta Diciembre de 2021 con 166 (85 intervención, 81 controlada) adultos afroamericanos que viven con el VIH en el condado de Los Ángeles, California [M (SD) = 49.0 (12,2) años; 76% de hombres]. La intervención incluyó sesiones de asesoramiento individualizadas, usando el estilo básico Motivacional para las entrevistas, para resolver los problemas de adherencia como también referencias para confrontar sus necesidades insatisfechas de los determinantes sociales de la salud (por ejemplo, servicios de vivienda y asistencia de alimentos). Las evaluaciones incluyeron la adherencia monitoreada electrónicamente; la carga viral del VIH; y encuestas de referencia, seguimiento a los 7 meses y seguimiento a los 13 meses sobre características sociodemográficas, el estigma del VIH, la desconfianza médica y divulgación del estado serológico respecto al VIH. Los efectos sobre la supresión viral del VIH, el estigma interiorizado y la revelación de información no fueron significativos. Además, Rise fue rentable según los estándares establecidos: El costo estimado por persona para alcanzar la adherencia óptima fue de 335 dólares por cada 10% de aumento en la adherencia. Las intervenciones como Rise, que se adaptan culturalmente a las necesidades de las poblaciones afroamericana, podrían ser óptimas para los estadounidenses afroamericanos que viven con el VIH.

RESUMO

Heavy alcohol use among people with HIV in sub-Saharan Africa is driven by household economics such as poverty and unemployment and has negative impacts on couple relationships. Multilevel interventions have the potential to reduce alcohol use and improve relationship outcomes by addressing the web of co-occurring economic, social, and dyadic factors. This objective of this study was to develop an economic and relationship-strengthening intervention for couples in Malawi, consisting of matched savings accounts with financial literacy training and a couples counseling component to build relationship skills. Informed by the ADAPT-ITT framework, we collected multiple rounds of focus group data with key stakeholders and couples to gain input on the concept, session content, and procedures, held team meetings with field staff and an international team of researchers to tailor the intervention to couples in Malawi, and refined the intervention manual and components. The results describe a rigorous adaptation process based on the eight steps of ADAPT-ITT, insights gained from formative data and modifications made, and a description of the final intervention to be evaluated in a pilot randomized clinical trial. The economic and relationship-strengthening intervention shows great promise of being feasible, acceptable, and efficacious for couples affected by HIV and heavy alcohol use in Malawi.

RESUMO

There are missed opportunities for the prevention of mother-to-child transmission of HIV (PMTCT) in Nigeria. However, little is known about the geographic variation. We examined the geographic pattern in the missed opportunities for HIV testing among antenatal care (ANC) attendees and initiation t on antiretroviral therapy (ART) in Nigeria. This study was an analysis of aggregated state-level data on 2,875,370 ANC attendees from the 2019 national HIV/AIDS health sector data. We performed descriptive statistics and explanatory spatial data analysis. Overall, the missed opportunity for HIV testing was 9.3%, ranging from 1.8% in the South South to 14.5% in the North West. The missed opportunity for HIV testing ranged from 0.2% in Imo State to 25.2% in Kaduna State. The local indicator of spatial association cluster map showed a concentration of cold spots in the South and hot spots in the North. The overall missed opportunity for ART was 9.5%, ranging from 7.4% in the South West to 11.1% in the NorthCentral. It was lowest in Adamawa State (0%), while Enugu State had the highest (32.2%). Missed opportunities for PMTCT among women attending ANC in Nigeria occur at varying degrees across the states, with higher levels in the northern region.

RESUMO

BACKGROUND: Coronavirus disease (COVID-19) pandemic has a significant influence on the access to healthcare services. This study aimed to understand the views and experiences of people living with HIV (PLHIV) about barriers to their access to antiretroviral therapy (ART) service in Belu district, Indonesia, during the COVID-19 pandemic. METHODS: This qualitative inquiry employed in-depth interviews to collect data from 21 participants who were recruited using a snowball sampling technique. Data analysis was guided by a thematic framework analysis. RESULTS: The findings showed that fear of contracting COVID-19 was a barrier that impeded participants' access to ART service. Such fear was influenced by their awareness of their vulnerability to the infection, the possibility of unavoidable physical contact in public transport during a travelling to HIV clinic and the widespread COVID-19 infection in healthcare facilities. Lockdowns, COVID-19 restrictions and lack of information about the provision of ART service during the pandemic were also barriers that impeded their access to the service. Other barriers included the mandatory regulation for travellers to provide their COVID-19 vaccine certificate, financial difficulty, and long-distance travel to the HIV clinic. CONCLUSIONS: The findings indicate the need for dissemination of information about the provision of ART service during the pandemic and the benefits of COVID-19 vaccination for the health of PLHIV. The findings also indicate the need for new strategies to bring ART service closer to PLHIV during the pandemic such as a community-based delivery system. Future large-scale studies exploring views and experiences of PLHIV about barriers to their access to ART service during the COVID-19 pandemic and new intervention strategies are recommended.

RESUMO

BACKGROUND: This study evaluated the effect of revisions to existing peer-counselor services, called Mentor Mothers (MM), at maternal and child health clinics on medication adherence for women living with HIV (WLWH) in Kenya and on early infant HIV testing. METHODS: The Enhanced Mentor Mother Program study was a 12-site, two-arm cluster-randomized trial enrolling pregnant WLWH from March 2017 to June 2018 (with data collection through September 2020). Six clinics were randomized to continued MM-supported standard care (SC). Six clinics were randomized to the intervention arm (INT = SC plus revised MM services to include more one-on-one interactions). Primary outcomes for mothers were defined as: (PO1) the proportion of days covered (PDC) with antiretroviral therapy (ART) ≥ 0.90 during the last 24-weeks of pregnancy; and (PO2) ≥ 0.90 PDC during the first 24-weeks postpartum. Secondary outcomes were infant HIV testing according to national guidelines (at 6, 24, and 48 weeks). Crude and adjusted risk differences between study arms are reported. RESULTS: We enrolled 363 pregnant WLHV. After excluding known transfers and subjects with incomplete data extraction, data were analyzed for 309 WLWH (151 SC, 158 INT). A small share achieved high PDC during the prenatal and postnatal periods (0.33 SC/0.24 INT achieved PO1; 0.30 SC/0.31 INT achieved PO2; crude or adjusted risk differences were not statistically significant). In addition, ~ 75% in both study arms completed viral load testing during year two after enrollment, with > 90% suppressed in both arms. For infants, ≥ 90% in both arms had at least one HIV test through study follow up (76 weeks) but testing on schedule according to PMTCT guidelines was uncommon. CONCLUSIONS: While national guidelines in Kenya recommended that all HIV-infected pregnant women take a daily antiretroviral regimen for life following a HIV diagnosis, results presented here indicate that a minor share achieved high medication coverage during the prenatal and postnatal periods analyzed. In addition, adjustments to Mentor-Mother services showed no improvement in study outcomes. The lack of effect for this behavioral intervention is relatively consistent with the existing literature to improve mother-infant outcomes along the PMTCT care cascade. CLINICAL TRIAL NUMBER: NCT02848235. Date of first trial registration 28/07/2016.

RESUMO

BACKGROUND: The community-based antiretroviral therapy delivery (CBART) model was implemented in Benue State in Nigeria to increase access of key populations living with HIV (KPLHIV) to antiretroviral treatment. Key populations (KP) are female sex workers, men who have sex with men, persons who inject drugs, and transgender people. Evidence shows that the CBART model for KP (KP-CBART) can improve HIV outcomes along the cascade of HIV care and treatment in sub-Saharan Africa. However, how KP-CBART works, for whom, why, and under what circumstances it generates specific outcomes are not yet clear. Therefore, the aim of this study is to identify the initial programme theory (IPT) of the KP-CBART in Benue State using a realist approach. METHOD: The study design is exploratory and qualitative, exploring the implementation of KP-CBART. We reviewed the intervention logic framework & guidelines for the KP-CBART in Nigeria, conducted a desk review of KP-CBART in Sub-Saharan Africa (SSA) and interviewed programme managers in the Benue HIV programme between November 2021 and April 2022. Findings were synthesized using the Context-Mechanism-Outcome (CMO) heuristic tool to explain the relationship between the different types of CBART models, contextual factors, actors, mechanisms and outcomes. Using a generative causality logic (retroduction and abduction), we developed, following a realist approach, CMO configurations (CMOc), summarized as an empirically testable IPT. RESULT: We developed 7 CMOc and an IPT of the KP-CBART. Where KPLHIV receive ART in a safe place while living in a setting of punitive laws, harassment, stigma and discrimination, KP will adhere to treatment and be retained in care because they feel safe and trust the healthcare providers. Where KPLHIV are involved in the design, planning and implementation of HIV services; medication adherence and retention in care will improve because KP clients perceive HIV services to be KP-friendly and participate in KP-CBART. CONCLUSION: Implementation of CBART model where KPLHIV feel safe, trust healthcare providers, and participate in HIV service delivery can improve medication adherence and retention in care. This programme hypothesis will be tested and refined in the next phase of the realist evaluation of KP-CBART.

RESUMO

The landscape for the development of therapeutics for prevention and treatment of human immunodeficiency virus (HIV)-1 infection has pivoted towards long-acting antiretrovirals (LA-ARVs). LA-ARVs have the potential to transform global implementation of HIV-1 prevention and treatment strategies. The ability to identify potential knowledge gaps early in development, proactively address missing information or data gaps, and strategically leverage all the available information is the key to streamline the development of safe and effective LA-ARV therapeutics. The purpose of this article is to discuss some potential considerations for development of LA-ARVs. Three possible drug development scenarios are briefly discussed and include developing (1) a novel LA-ARV, (2) a novel LA formulation of an approved oral ARV, and (3) an LA pro-drug of an approved oral ARV. For each of these scenarios, we briefly describe what type(s) of information may be helpful and discuss potential opportunities to leverage available information. Additionally, we discuss some unique LA-ARV drug development considerations, including the use of an oral lead-in, and assessing the impact of residual ARV exposures on subsequent regimens and evaluation of LA-ARVs in specific populations. We strongly believe that efficient integration of multidisciplinary knowledge can advance the development, availability, and accessibility of therapeutics not only for HIV-1 prevention and treatment but also for other chronic viral infections.

RESUMO

Dihydroartemisinin-piperaquine, an artemisinin-based combination therapy, has been identified as a promising agent for intermittent preventive treatment of malaria in pregnancy. However, in pregnant women living with HIV (PLWH), efavirenz-based antiretroviral therapy (ART) significantly reduces the plasma exposure of piperaquine. In an open-label, nonrandomized, fixed-sequence, pharmacokinetic study, we compared piperaquine plasma concentrations in 13 pregnant women during a 3-day treatment course of dihydroartemisinin-piperaquine when coadministered with efavirenz-based versus dolutegravir-based ART in the second or third trimester of pregnancy. Piperaquine concentrations were measured over a 28-day period, while on efavirenz-based ART and after switching to dolutegravir-based ART. Noncompartmental analysis was performed, and geometric mean ratios (GMRs) and 90% confidence intervals (CIs) were generated to compare piperaquine pharmacokinetic parameters between these two treatment periods. Compared with efavirenz-based ART, coadministration of dihydroartemisinin-piperaquine and dolutegravir-based ART resulted in a 57% higher overall piperaquine exposure (area under the concentration-time curve from 0 to 672 h [AUC0-672 h]) (GMR, 1.57; 90% CI, 1.28 to 1.93). Piperaquine's day 7 concentrations were also 63% higher (GMR, 1.63; 90% CI, 1.29 to 2.11), while day 28 concentrations were nearly three times higher (GMR, 2.96; 90% CI, 2.25 to 4.07). However, the maximum piperaquine concentration (Cmax) remained similar (GMR, 1.09; 90% CI, 0.79 to 1.49). Dihydroartemisinin-piperaquine was well tolerated, with no medication-related serious adverse events observed in this small study. Compared with efavirenz-based ART, a known inducer of piperaquine metabolism, dolutegravir-based ART resulted in increased overall piperaquine exposure with pharmacokinetic parameter values that were similar to those published previously for pregnant and nonpregnant women. Our findings suggest that the efficacy of dihydroartemisinin-piperaquine will be retained in pregnant women on dolutegravir. (The study was registered on PACTR.samrc.ac.za [PACTR201910580840196].).

RESUMO

INTRODUCTION: HIV is still a central public health issue in Latin America, disproportionally affecting key populations. Knowledge and access to biomedical prevention strategies, including treatment as prevention (TASP) or undetectable = untransmissible (U=U), pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), are the first steps to increasing uptake. We used data from the Latin American MSM Internet Survey (LAMIS) to describe knowledge and access to biomedical HIV prevention strategies among gay, bisexual, transgender and other men who have sex with men (MSM) living in 18 Latin American countries. METHODS: We compared LAMIS data across countries and according to age categories using frequencies and percentages. We also used multivariable models to explore whether age, gender identity, sexual identity, steady partnership, HIV status and education were independently associated with outcomes. RESULTS: In all, 55 924 participants were included. Most were cisgender (99%) and identified as gay/homosexual (77%) or bisexual (17%). Schooling levels were very high, with 89% reporting highest attained education as tertiary level, university or post-graduation. In total, 16% had been previously diagnosed with HIV; of those, rates of undetectable viral load varied from 60% in Venezuela to 83% in Brazil. Overall, 54%, 54% and 52% of participants already knew about PEP, PrEP and U=U, respectively. Participants from Brazil and those aged between 26 and 55 years, living with diagnosed HIV and having a gay/homosexual identity had greater levels of awareness about biomedical prevention strategies. CONCLUSIONS: Our study highlights gaps in HIV prevention campaigns directed to MSM in Latin America resulting in low uptake of biomedical prevention methods.

RESUMO

PURPOSE OF REVIEW: Pregnant people living with HIV (PLWH) are at especially high risk for progression from latent tuberculosis infection (LTBI) to active tuberculosis (TB) disease. Among pregnant PLWH, concurrent TB increases the risk of complications such as preeclampsia, intrauterine fetal-growth restriction, low birth weight, preterm-delivery, perinatal transmission of HIV, and admission to the neonatal intensive care unit. The grave impact of superimposed TB disease on maternal morbidity and mortality among PLWH necessitates clear guidelines for concomitant therapy and an understanding of the pharmacokinetics (PK) and potential drug-drug interactions (DDIs) between antitubercular (anti-TB) agents and antiretroviral therapy (ART) in pregnancy. RECENT FINDINGS: This review discusses the currently available evidence on the use of anti-TB agents in pregnant PLWH on ART. Pharmacokinetic and safety studies of anti-TB agents during pregnancy and postpartum are limited, and available data on second-line and newer anti-TB agents used in pregnancy suggest that several research gaps exist. DDIs between ART and anti-TB agents can decrease plasma concentration of ART, with the potential for perinatal transmission of HIV. Current recommendations for the treatment of LTBI, drug-susceptible TB, and multidrug-resistant TB (MDR-TB) are derived from observational studies and case reports in pregnant PLWH. While the use of isoniazid, rifamycins, and ethambutol in pregnancy and their DDIs with various ARTs are well-characterized, there is limited data on the use of pyrazinamide and several new and second-line antitubercular drugs in pregnant PLWH. Further research into treatment outcomes, PK, and safety data for anti-TB agent use during pregnancy and postpartum is urgently needed.

RESUMO

PURPOSE OF REVIEW: This review summarizes the recent advancements and future directions of digital pill systems (DPS) - which utilize ingestible sensors to directly measure medication ingestion events in real-time - in the context of HIV prevention and treatment. RECENT FINDINGS: Two DPS are cleared by the US Food and Drug Administration. The bioequivalence and stability of digitized pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART) have been established, and pilot studies have demonstrated the feasibility and acceptability of using DPS for PrEP and ART adherence measurement. Important bioethical and implementation considerations have been identified for future clinical trials. Continued technological advancement may reduce barriers to use, and integration of DPS into behavioral interventions may facilitate adherence improvement efforts. DPS represent an innovative tool for PrEP and ART adherence measurement. Future work will optimize the technology to reduce operational barriers. DPS have significant potential for expansion across a diverse array of diseases, though key bioethical considerations must be examined prior to large-scale implementation.

RESUMO

HIV positive key population (KP) often face health system and social barriers to HIV care. KP include sex workers, men who have sex with men, persons who inject drugs, transgender people, and people in prisons and other closed settings. Community-based ART service delivery (CBART) has the potential to increase access to antiretroviral treatment (ART) and enhance retention in care. This scoping review summarized the evidence on the effect of CBART along the continuum of HIV care among KP in sub-Saharan Africa. We searched Pubmed, Web of Science, Google scholar, and NGO websites for articles published between 2010 and April 2020. We synthesized the involvement of KP community members or lay providers in medical task provision, and outcomes along the continuum of HIV care. Of 3,330 records identified, 66 were eligible for full test screening, out of which 12 were included in the review. CBART for KP was provided through: (a) community drop-in-centres, (b) community drop-in-centres plus mobile team, or (c) community-based health centres. KP were engaged as peer educators and they provided services such as community mobilisation activities for HIV testing and ART, ART adherence counselling, and referral for ART initiation. Across the KP-CBART studies, outcomes in terms of ART uptake, adherence to ART, retention in care and viral suppression were at least as good as those obtained for KP attending facility-based care. KP-CBART was as effective as facility-based care. To achieve the UNAIDS 95-95-95 target in sub-Saharan Africa, national programmes should scale-up KP-CBART to complement facility-based care.

RESUMO

To support translation of evidence-based interventions into practice for HIV patients at high risk of treatment failure, we conducted qualitative research in Cape Town, South Africa. After local health officials vetted interventions as potentially scalable, we held 41 in-depth interviews with patients with elevated viral load or a 3-month treatment gap at community clinics, followed by focus group discussions (FGDs) with 20 providers (physicians/nurses, counselors, and community health care workers). Interviews queried treatment barriers, solutions, and specific intervention options, including motivational text messages, data-informed counseling, individual counseling, peer support groups, check-in texts, and treatment buddies. Based on patients' preferences, motivational texts and treatment buddies were removed from consideration in subsequent FGDs. Patients most preferred peer support groups and check-in texts while individual counseling garnered the broadest support among providers. Check-in texts, peer support groups, and data-informed counseling were also endorsed by provider sub-groups. These strategies warrant attention for scale-up in South Africa and other resource-constrained settings.

RESUMO

Long-acting injectable (LAI) modalities have been developed for ART and PrEP. Women face unique barriers to LAI use yet little research has examined women's perceptions of potential LAI HIV therapy candidates. We conducted 89 in-depth interviews at six Women's Interagency HIV Study (WIHS) sites with women living with HIV (n = 59) and HIV-negative women (n = 30) from 2017 to 2018. Interviews were recorded, transcribed, and analyzed using thematic content analysis. Participants identified specific sub-populations who could most benefit from LAI over daily pills: (1) young people; (2) women with childcare responsibilities; (3) people with adherence-related psychological distress; (4) individuals with multiple sex partners; and (5) people facing structural insecurities such as homelessness. Women are underserved by current HIV care options and their perspectives are imperative to ensure a successful scale-up of LAI PrEP and LAI ART that prioritizes equitable access and benefit for all individuals.
