Abstract
Fewer adolescents achieve viral suppression compared to adults. One impediment may be a history of adverse childhood experiences (ACEs). To better develop targets and timeframes for intervention, this study created more robust estimates of the impact of cumulative adversity on viral suppression, tested whether the association is sensitive to the timing of adversity, and simultaneously tested several potential mechanisms. We focus on males, who have lower viral suppression than females and who may contribute to disproportionate incidence among young women. We recruited 251 male perinatally HIV-infected adolescents aged 15-19 from HIV clinics in Soweto, South Africa. Adversity was captured using the Adverse Childhood Experience - International Questionnaire (ACE-IQ). Viral load was measured using blood samples; viral suppression was defined as <20 copies/mL. Indicators of medication adherence, depression, post-traumatic stress disorder (, and substance misuse were captured. A series of pathway analysis were performed. Our sample experienced a median of 7 lifetime and 4 past-year adversities. Less than half (44%) exhibited viral suppression. Adversity demonstrated a significant association with suppression; depression mediated the association. Primary prevention of adversity among children living with HIV is paramount, as is addressing the subsequent mental and behavioral health challenges that impede viral suppression among adolescents.

Patterns of engagement in care during clients' first 12 months after HIV treatment initiation in South Africa: A retrospective cohort analysis using routinely collected data. PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0002956.

Abstract
Retention on antiretroviral therapy (ART) during the early treatment period is one of the most serious challenges facing HIV programs, but the timing and patterns of early disengagement from care remain poorly understood. We describe patterns of engagement in HIV care during the first year after treatment initiation. We analysed retrospective datasets of routinely collected electronic medical register (EMR) data for ≥18-year-old clients who initiated ART at public sector clinics in South Africa after 01/01/2018 and had ≥14 months of potential follow-up. Using scheduled visit dates, we characterized engagement in care as continuous (no treatment interruption), cyclical (at least one visit >28 days late with a return visit observed) or disengaged (visit not attended and no evidence of return). We report 6- and 12-month patterns of retention in care and viral suppression. Among 35,830 participants (65% female, median age 33), in months 0-6, 59% were continuously in care, 14% had engaged cyclically, 11% had transferred to another facility, 1% had died, and 16% had disengaged from care at the initiating facility. Among disengagers in the first 6 months, 58% did not return after their initiation visit. By 12 months after initiation, the overall proportion disengaged was 23%, 45% were classified as continuously engaged in months 7-12, and only 38% of the cohort had maintained continuous engagement at both the 6- and 12-month endpoints. Participants who were cyclically engaged in months 0-6 were nearly twice as likely to disengage in months 7-12 as were continuous engagers in months 0-6 (relative risk 1.76, 95% CI:1.61-1.91) and were more likely to have an unsuppressed viral load by 12 months on ART (RR = 1.28; 95% CI1.13-1.44). The needs of continuous and cyclical engagers and those disengaging at different timepoints may vary and require different interventions or models of care.

Abstract
Youth living with HIV are at higher risk than adults of disengaging from HIV care. Differentiated models of care such as community delivery of antiretroviral therapy (ART) may improve treatment outcomes. We investigated outcomes across the HIV cascade among youth accessing HIV services in a community-based setting. This study was nested in a cluster-randomised controlled trial (CHIEDZA: Clinicaltrials.gov, Registration Number: NCT03719521) conducted in three provinces in Zimbabwe and aimed to investigate the impact of a youth-friendly community-based package of HIV services, integrated with sexual and reproductive health services for youth (16-24 years), on population-level HIV viral load (VL). HIV services included HIV testing, ART initiation and continuous care, VL testing, and adherence support. Overall 377 clients were newly diagnosed with HIV at CHIEDZA, and linkage to HIV care was confirmed for 265 (70.7%, 234 accessed care at CHIEDZA and 31 with other providers); of these 250 (94.3%) started ART. Among those starting ART at CHIEDZA who did not transfer out and had enough follow up time (>6 months), 38% (68/177) were lost-to-follow-up within six months. Viral suppression (HIV Viral Load <1000 copies/ml) among those who had a test at 6 months was 90% (96/107). In addition 1162 clients previously diagnosed with HIV accessed CHIEDZA; 714 (61.4%) had a VL test, of whom 565 (79.1%) were virally suppressed. This study shows that provision of differentiated services for youth in the community is feasible. Linkage to care and retention during the initial months of ART was the main challenge and needs concerted attention to achieve the ambitious 95-95-95 UNAIDS targets.

Abstract
The global HIV response has made tremendous progress but is entering a new phase with additional challenges. Scientific innovations have led to multiple safe, effective, and durable options for treatment and prevention, and long-acting formulations for 2-monthly and 6-monthly dosing are becoming available with even longer dosing intervals possible on the horizon. The scientific agenda for HIV cure and remission strategies is moving forward but faces uncertain thresholds for success and acceptability. Nonetheless, innovations in prevention and treatment have often failed to reach large segments of the global population (eg, key and marginalised populations), and these major disparities in access and uptake at multiple levels have caused progress to fall short of their potential to affect public health. Moving forward, sharper epidemiologic tools based on longitudinal, person-centred data are needed to more accurately characterise remaining gaps and guide continued progress against the HIV epidemic. We should also increase prioritisation of strategies that address socio-behavioural challenges and can lead to effective and equitable implementation of existing interventions with high levels of quality that better match individual needs. We review HIV epidemiologic trends; advances in HIV prevention, treatment, and care delivery; and discuss emerging challenges for ending the HIV epidemic over the next decade that are relevant for general practitioners and others involved in HIV care.

Abstract
BACKGROUND Young people living with HIV (YPLWH) experience poorer rates of virological suppression compared with adults. Differentiated service delivery models for YPLWH are urgently needed to address this disparity. SETTING Participants were recruited from an HIV treatment clinic near Cape Town, South Africa. METHODS We conducted a longitudinal pilot study to examine the acceptability, feasibility, and preliminary effectiveness of a courier ART delivery and SMS support intervention to retain YPLWH (13-24 years) in care during COVID-19. YPLWH had the option to enroll in the courier service and were randomized 1:1 to receive adherence support via a weekly SMS. Modified Poisson regression was used to estimate the preliminary effectiveness of the courier intervention on viral suppression (HIV-1 RNA <200 copies/mL) at months 3 and 6. RESULTS Among 215 participants, 82% elected to enroll in the courier ART service at baseline, 41% reported receiving a delivery in the past 3 months at month 3, and 49% reported receiving a delivery in the past 3 months at month 6. Among those who received a delivery, most (91%-100%) rated the intervention as acceptable. Participants who reported receiving a delivery in the past 3 months at month 3 were 1.26 (95% CI: 1.05, 1.54) times as likely to have a suppressed viral load at month 3 and 1.21 (0.99, 1.48) times as likely at month 6, controlling for potential confounders. CONCLUSIONS Findings reveal high uptake and acceptability of a courier ART delivery intervention among YPLWH and promising evidence for its effectiveness in increasing the probability of viral suppression. A fully powered trial is warranted.

Abstract
AIMS Half of young adults diagnosed with HIV in South Africa start antiretroviral therapy (ART). We developed and field tested a facilitator-guided peer support group called Yima Nkqo ("Standing Tall" in isiXhosa) to promote treatment initiation for young adults newly diagnosed with HIV in communities around Cape Town. METHODS Following an adapted version of the UK Medical Research Council's framework for developing complex interventions, we 1) identified evidence on previous interventions to improve ART uptake in sub-Saharan Africa; 2) collected and analyzed qualitative data on the acceptability of our proposed intervention; 3) proposed a theoretical understanding of the process of behavior change; and 4) developed an intervention manual and feedback tools. During field-testing, participant feedback on intervention acceptability, and team feedback on consistency of content delivery and facilitation quality, were analyzed using an iterative, rapid-feedback evaluation approach. In-depth written and verbal summaries were shared in weekly team meetings. Team members interpreted feedback, identified areas for improvement, and proposed suggestions for intervention modifications. RESULTS Based on our formative research, we developed three, 90-minute sessions with content including HIV and ART education, reflection on personal resources and strengths, practice disclosing one's status, strategies to overcome stressors, and goal setting to start treatment. A lay facilitator was trained to deliver intervention content. Two field testing groups (five and four participants, respectively) completed the intervention. Participants highlighted that strengths of Yima Nkqo included peer support, motivation, and education about HIV and ART. Team feedback to the facilitator ensured optimal consistency of intervention content delivery. CONCLUSIONS Iteratively developed in collaboration with youth and healthcare providers, Yima Nkqo is a promising new intervention to improve treatment uptake among young adults with HIV in South Africa. The next phase will be a pilot randomized controlled trial of Yima Nkqo (ClinicalTrials.gov Identifier: NCT04568460).

Abstract
INTRODUCTION Street-connected young people (SCY) experience structural and social barriers to engaging in the HIV prevention-care continuum. We sought to elicit recommendations for interventions that may improve SCY's engagement along the HIV prevention-care continuum from healthcare providers, policymakers, community members and SCY in Kenya. METHODS This qualitative study was conducted in Uasin Gishu, Trans Nzoia, Bungoma, Nakuru and Kitale counties in Kenya between May 2017 and September 2018 to explore and describe the public perceptions of, and proposed and existing responses to, the phenomenon of SCY. This secondary analysis focuses on a subset of data interviews that investigated SCY's healthcare needs in relation to HIV prevention and care. We conducted 41 in-depth interviews and seven focus group discussions with 100 participants, of which 43 were SCY. In total, 48 participants were women and 52 men. RESULTS Our analysis resulted in four major themes corresponding to stages in the HIV prevention-care continuum for key populations. We identified the need for an array of strategies to engage SCY in HIV prevention and testing services that are patient-centred and responsive to the diversity of their circumstances. The use of pre-exposure prophylaxis was a biomedical prevention strategy that SCY and healthcare providers alike stressed the need to raise awareness around and access to for SCY. Several healthcare providers suggested peer-based approaches for engaging SCY throughout the continuum. However, SCY heavily debated the appropriateness of using peer-based methods. Structural interventions, such as the provision of food and housing, were suggested as strategies to improve antiretroviral therapy adherence. CONCLUSIONS This study identified contextually relevant interventions that should be adapted and piloted for use with SCY. Education and sensitization of SCY and healthcare providers alike were identified as possible strategies, along with affordable housing and anti-poverty strategies as cash transfers and provision of food. Peer-based interventions are a clear option but require SCY-specific adaptation to be implemented effectively.

Abstract
Background Linkage between health databases typically requires identifiers such as patient names and personal identification numbers. We developed and validated a record linkage strategy to combine administrative health databases without the use of patient identifiers, with application to South Africa's public sector HIV treatment program. Methods We linked CD4 counts and HIV viral loads from South Africa's HIV clinical monitoring database (TIER.Net) and the National Health Laboratory Service (NHLS) for patients receiving care between 2015-2019 in Ekurhuleni District (Gauteng Province). We used a combination of variables related to lab results contained in both databases (result value; specimen collection date; facility of collection; patient year and month of birth; and sex). Exact matching linked on exact linking variable values while caliper matching applied exact matching with linkage on approximate test dates (± 5 days). We then developed a sequential linkage approach utilising specimen barcode matching, then exact matching, and lastly caliper matching. Performance measures were sensitivity and positive predictive value (PPV); share of patients linked across databases; and percent increase in data points for each linkage approach. Results We attempted to link 2,017,290 lab results from TIER.Net (representing 523,558 unique patients) and 2,414,059 lab results from the NHLS database. Linkage performance was evaluated using specimen barcodes (available for a minority of records in TIER.net) as a "gold standard". Exact matching achieved a sensitivity of 69.0% and PPV of 95.1%. Caliper-matching achieved a sensitivity of 75.7% and PPV of 94.5%. In sequential linkage, we matched 41.9% of TIER.Net labs by specimen barcodes, 51.3% by exact matching, and 6.8% by caliper matching, for a total of 71.9% of labs matched, with PPV=96.8% and Sensitivity = 85.9%. The sequential approach linked 86.0% of TIER.Net patients with at least one lab result to the NHLS database (N=1,450,087). Linkage to the NHLS Cohort increased the number of laboratory results associated with TIER.Net patients by 62.6%. Conclusions Linkage of TIER.Net and NHLS without patient identifiers attained high accuracy and yield without compromising patient privacy. The integrated cohort provides a more complete view of patients' lab history and could yield more accurate estimates of HIV program indicators.

Abstract
New HIV infections and AIDS-related deaths among children and adolescent girls and young women (aged 15-24 years) in eastern and southern Africa continue to occur at unacceptably high rates. The COVID-19 pandemic has also severely undermined ongoing initiatives for HIV prevention and treatment, threatening to set the region back further in its efforts to end AIDS by 2030. Major impediments exist to attaining the UNAIDS 2025 targets among children, adolescent girls, young women, young mothers living with HIV, and young female sex workers residing in eastern and southern Africa. Each population has specific but overlapping needs with regard to diagnosis and linkage to and retention in care. Urgent action is needed to intensify and improve programmes for HIV prevention and treatment, including sexual and reproductive health services for adolescent girls and young women, HIV-positive young mothers, and young female sex workers.

Abstract
BACKGROUND In South Africa, at least 7.5 million people (age ≥15 years) are living with Human Immunodeficiency Virus (HIV). In 2020, 220,000 new infections occurred, approximately one-third of which were among cisgender adolescent girls and women (age ≥15 years). The perspectives of pregnant adolescent girls and young women (AGYW) as key, targeted end-users of pre-exposure prophylaxis (PrEP) in this setting are not well known. METHODS We purposively recruited participants enrolled in an ongoing cohort study at an urban antenatal clinic in Cape Town, South Africa for in-depth interviews between July-September 2020. We restricted our analysis to pregnant AGYW (age: 16-25 years) who initiated daily oral PrEP (Tenofovir/Emtricitabine) antenatally and self-reported either high PrEP persistence (≥25 days in the past 30 days and no missed PrEP collection), or low PrEP persistence and/or discontinuation (missing >5 days in the last 30 days or missed PrEP collection). The findings were organized thematically, per the adapted Health Behavior Model (2000), using Nvivo-v.1.5. RESULTS We interviewed 18 AGYW (mean age = 22 years), at a mean of 14 weeks postpartum. Higher self-esteem and high-quality study provider-client relationships, including empathic psychosocial support, facilitated PrEP continuation. Reported barriers included unstable social structure characteristics (i.e., financial hardship) and individual factors (i.e., unintended pregnancy, parental rejection, and inadequate peer- and [non-cohabiting] partner support). Participants self-perceived a need for PrEP, feeling susceptible to non-consensual, forced sex, or considering partners' (presumed) sexual risk-taking. Limited community awareness regarding PrEP availability and/or perceived complexity in navigating health system access to PrEP, impede continuation. CONCLUSIONS PrEP-focused healthcare access pathways for pregnant and postpartum AGYW need to be simplified. Further research is needed on health system determinants (i.e., structural barriers, provider-client interactions, and related outcomes) of oral PrEP utilization. In 2022, South Africa announced regulatory approval of long-acting PrEP options (i.e., the dapivirine ring for non-pregnant women and injectable cabotegravir, respectively); these may mitigate implementation barriers reported in this study. However, the safety and efficacy of long-acting PrEP (e.g., injectables, implants) among pregnant or breastfeeding women, specifically, remains to be confirmed in this setting.

BMC Public Health 2023; 23:458.

Abstract
BACKGROUND Long-term engagement in HIV care is essential to achieving and maintaining viral suppression. Adolescents living with HIV (ALHIV) experience many barriers to remaining engaged in care and treatment programs. Higher attrition among adolescents compared to adults remains a huge concern due to unique psychosocial and health systems challenges adolescents face, and recently the COVID-19 pandemic effects. We report on determinants and rates of retention in care in adolescents aged 10-19 years enrolled on antiretroviral therapy (ART) in Windhoek, Namibia. METHODS A retrospective cohort analysis of routine clinical data of 695 adolescents aged 10-19 years enrolled for ART at 13 Windhoek district public healthcare facilities, between January 2019 and December 2021 was conducted. Anonymized patient data were extracted from an electronic database and registers. Bivariate and Cox proportional hazards analysis were performed to determine factors associated with retention in care among ALHIV at 6, 12, 18, 24 and 36 months. Retention in care trends were also described using the Kaplan-Meier survival analysis. RESULTS The retention in care rates at 6, 12, 18, 24 and 36 months were 97.7%, 94.1%, 92.4%, 90.2%, and 84.6%, respectively. Our study population had predominantly treatment-experienced adolescents, who initiated ART between birth and 9 years (73.5%), were on treatment for > 24 months (85.0%), and on first-line ART (93.1%). After controlling for confounders, the risk of dropping out of care was increased for older adolescents aged 15-19 years (aHR = 1.964, 95% CI 1.033-3.735); adolescents on switched ART regimens (Second line + Third line regimen) (aHR = 4.024, 95% CI 2.021-8.012); adolescents who initiated ART at 15-19 years (aHR = 2.179, 95%CI 1.100-4.316); and male adolescents receiving ART at a PHC clinic (aHR = 4.322, 1.332-14.024). Conversely, the risk of ALHIV dropping out of care decreased for adolescents whose TB screen results were negative (aHR = 0.215, 95% CI 0.095-0.489). CONCLUSION Retention in care rates among ALHIV in Windhoek do not meet the UNAIDS revised target of 95%. Gender-specific interventions are needed to keep male and older adolescents motivated and engaged in long-term care, and to promote adherence amongst those adolescents who were initiated on ART in late adolescence (15-19 years).

Abstract
BACKGROUND Adolescents living with HIV exhibit lower levels of adherence to antiretroviral therapy (ART) than other age groups. Poverty is a key barrier to ART adherence. This study aims at understanding how alleviating poverty through structural and internal pathways can help increase ART adherence among adolescents. SETTING Eastern Cape province, South Africa. METHODS One thousand forty-six adolescents living with HIV were recruited from 53 public health care facilities and interviewed at 3 data collection waves with a retention rate of 89% and a mortality rate of 3%. Data were collected by face-to-face, device-assisted interviews. Hybrid probit regressions and a structural equation path analysis were used to estimate the association between poverty reduction (increased access to basic necessities) and the pathways by which it could improve ART adherence. RESULTS Self-reported ART adherence ranged from an average of 66% (n = 615) at baseline to 75% (n = 700) in the last wave. Within-person and between-person improvements in economic well-being were associated with significant increases in adolescent ART adherence. On average, adolescents with access to 3 additional basic needs experienced a 4 percentage-point increase in the probability of ART adherence. Structural pathways to improved ART adherence included participants having enough money to travel to the clinic and sufficient food to eat when taking medication. Internal pathways included improved psychological well-being and reduced internalized HIV stigma. CONCLUSION Poverty reduction programs such as HIV-sensitive social protection can address structural and psychological pathways to increase ART adherence among economically disadvantaged adolescents by incentivizing demand-side interventions and the provision of quality essential services.

Abstract
Few studies have examined the independent effects of different manifestations of HIV stigma experiences on health outcomes among youth living with HIV in low- and middle-income countries. We examined the association of internalized, enacted, and perceived HIV stigmas with medication adherence, self-esteem, depression, and barriers to adherence. Young people living with HIV aged 18-21 years (N = 120) were purposively sampled from two health facilities in Eastern Province, Zambia, and completed self-report measures. Results indicated heterogeneous associations. Internalized HIV stigma was positively associated with depression and negatively associated with adherence, adherence motivation, behavioral adherence skills, and self-esteem. Perceived stigma was negatively associated with self-esteem. No significant association was observed between enacted stigma and health outcomes. The complexity of HIV stigma requires a precise explication of the associations among different HIV stigma experiences and outcomes, which can inform the development of stigma reduction interventions targeting one or more stigma experiences.

Abstract
PURPOSE South Africa's National Health Laboratory Service (NHLS) National HIV Cohort was established in 2015 to facilitate monitoring, evaluation and research on South Africa's National HIV Treatment Programme. In South Africa, 84.8% of people living with HIV know their HIV status; 70.7% who know their status are on ART; and 87.4% on ART are virologically suppressed. PARTICIPANTS The NHLS National HIV Cohort includes the laboratory data of nearly all patients receiving HIV care in the public sector since April 2004. Patients are included in the cohort if they have received a CD4 count or HIV RNA viral load (VL) test. Using an anonymised unique patient identifier that we have developed and validated to linked test results, we observe patients prospectively through their laboratory results as they receive HIV care and treatment. Patients in HIV care are seen for laboratory monitoring every 6-12 months. Data collected include age, sex, facility location and test results for CD4 counts, VLs and laboratory tests used to screen for potential treatment complications. FINDINGS TO DATE From April 2004 to April 2018, 63 million CD4 count and VL tests were conducted at 5483 facilities. 12.6 million unique patients had at least one CD4 count or VL, indicating they had accessed HIV care, and 7.1 million patients had a VL test indicating they had started antiretroviral therapy. The creation of NHLS National HIV Cohort has enabled longitudinal research on all lab-monitored patients in South Africa's national HIV programme, including analyses of (1) patient health at presentation; (2) care outcomes such as 'CD4 recovery', 'retention in care' and 'viral resuppression'; (3) patterns of transfer and re-entry into care; (4) facility-level variation in care outcomes; and (5) impacts of policies and guideline changes. FUTURE PLANS Continuous updating of the cohort, integration with available clinical data, and expansion to include tuberculosis and other lab-monitored comorbidities.

Abstract
Adolescents and young people living with HIV are at risk of disengaging from HIV care at all stages of the care cascade. Differentiated models of care offer simplified HIV-service delivery options in the hope of improving treatment outcomes, including retention on antiretroviral therapy. However, it remains unclear how successful and widespread these models are for adolescents in sub-Saharan Africa, where the burden of HIV is the greatest. Very few differentiated models of care specifically targeted to adolescents can be found and this priority group are currently ineligible from several models that exist. Where differentiated care has been made available to adolescents, data on the implementation and effectiveness of these interventions remain scarce. Despite this scarcity of evidence on the effectiveness of differentiated care among adolescent populations, several interventions, particularly community-based groups with peer navigators or supporters, might have potential to increase the reach, effectiveness, and adoption of differentiated care in adolescent HIV-care programmes.

Abstract
Background Progress has been made to increase access to antiretroviral therapy (ART) for adolescents living with HIV (ALHIV) to improve their survival, but ALHIV still have worse treatment adherence and viral suppression compared to adults and children. Objective To determine the prevalence of viral suppression and the associated factors among adolescents aged 10–19 years on ART at an urban public primary healthcare facility in the Sedibeng district, Gauteng. Method A cross-sectional survey was conducted among 192 adolescents who were on ART for at least six months between 2015 and 2018. A self-developed data extraction tool was used to collect data from the Tier.Net electronic database and clinical folders. Data were captured on Microsoft Excel, and descriptive and inferential analyses were performed using SPSS 27 statistical software. Results The median age at ART initiation of adolescents was 9.0 years (interquartile range [IQR]: 5.0–12.0), and the median duration on ART was 70.5 (IQR: 30.25–105.5) months. The prevalence of viral suppression (< 1000 copies/mL) among adolescents on ART was 74%, with 41% achieving full suppression (< 50 copies/mL). Those adolescents who reported optimal ART adherence were more likely to be virally suppressed compared to those who reported poor adherence (98.1% vs 25.0%; p ≤ 0.001). Conclusion Adolescent viral suppression of 74% is higher than in comparable sites, but still way too short of the UNAIDS target of 90%. We recommend adherence support for adolescents to achieve viral suppression. Contribution The study highlights the urgent need for targeted adherence support interventions for adolescents living with HIV on antiretroviral therapy to improve rates of viral suppression to meet UNAIDS target of 95%.

Temporal changes in paediatric and adolescent HIV outcomes across the care continuum in Zambia: an interrupted time-series analysis. THE LANCET HIV 2022; 9:e563-e573. [PMID: 35905754 PMCID: PMC9394542 DOI: 10.1016/s2352-3018(22)00127-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 04/13/2022] [Accepted: 04/22/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Paediatric and adolescent HIV treatment programmes in sub-Saharan Africa have rapidly expanded and evolved over the past decade. Real-world evidence of how the implementation of new policies over time has affected treatment outcomes is inadequate, but is crucial for guiding the implementation of the next phases of the HIV treatment response for children. We examined how treatment outcomes in Zambia's national paediatric and adolescent HIV treatment programmes have changed over time as new policies were implemented. METHODS We used data from Zambia's routine electronic health record to analyse children and adolescents living with HIV who were antiretroviral therapy (ART) naive between the ages of 0 and 19 years who were newly enrolled in care between Jan 1, 2011, and March 31, 2019, at 102 health facilities in Lusaka and Western provinces supported by the Centre for Infectious Disease Research in Zambia. Sociodemographic factors, clinical data, facility-level data, and visit history were obtained from the national electronic health record and laboratory systems used in routine HIV care in Zambia. We aimed to characterise the changes in the distribution of the age and sex of new enrolees over time. We used an interrupted time-series design to examine the rates of ART initiation, retention in care, time to ART initiation, and first-line ART regimens among new enrolees across different age strata as they changed over time with the adoption of new ART guidelines in 2014 and 2017. FINDINGS Between Jan 1, 2011, and March 31, 2019, 26 214 children and adolescents living with HIV who were ART naïve were newly enrolled at one of 102 ART facilities in two provinces in Zambia. Rates of new enrolees increased by 25-35% among children younger than 15 years over time, but by 92·3% between 2011 and 2017 among adolescents, with the largest absolute increase among adolescent girls. Rates of ART initiation increased steadily and in parallel across all age groups from before the implementation of the 2014 guidelines to after the implementation of the 2017 guidelines (<2 years, 42·4% for 2014 and 81·6% for 2017; 2 to <5 years, 39·3% for 2014 and 82·8% for 2017; 5 to <15 years, 49·2% for 2014 and 86·6% for 2017; 15 to 19 years, 52·4% for 2014 and 86·2% for 2017); median time to ART initiation went from 2-3 months to same-day initiation during this same time period. Rates of retention on ART 6 months after linkage saw much smaller improvements over time (<2 years, 35·4% for 2014 and 52·0% for 2017; 2 to <5 years, 40·2% for 2014 and 54·4% for 2017; 5 to <15 years, 46·7% for 2014 and 63·4% for 2017; 15 to 19 years, 40·1% for 2014 and 52·7% for 2017). INTERPRETATION Improvements in ART initiation occurred largely in parallel across age groups over time, despite universal treatment being implemented at different timepoints for different ages. Although the rates of ART initiation reach high levels, retention on ART was low. This analysis provides a comprehensive examination of how paediatric and adolescent outcomes have evolved over the past decade in Zambia and identifies where more targeted efforts will be needed over the next decade.

Abstract
Background In 2019, about 1.7 million adolescents between the ages of 10 and 19 years were living with HIV worldwide, of which 170 000 were newly infected with HIV in 2019. South Africa has the highest number of persons living with HIV. Although there has been major improvement in access to antiretroviral therapy (ART), it is still unclear what proportion of adolescents (aged 10–19 years) are virally suppressed in the provinces of South Africa. Objectives To determine the prevalence of and the factors associated with viral suppression among adolescents (10–19 years) on ART in the Thabo Mofutsanyane District Municipality of the Free State province of South Africa. Method A retrospective cross-sectional analysis of demographic, clinical and treatment-related information that were extracted from an electronic database was conducted using Statistical Package for the Social Sciences version 26. Results The median duration on ART was 6.58 years. Although 78% (n = 4520) of adolescents living with HIV who were on ART achieved viral suppression (< 1000 copies/mL), only 9.5% (n = 430) were fully suppressed at < 50 copies/mL. In multivariate analysis, the odds of being virally suppressed reduced with increasing age at ART initiation. Adolescents with CD4 counts greater than 500 cells/mm3 at baseline had a higher odds ratio of viral suppression (adjusted odds ratio [AOR]: 1.77; confidence interval [CI]: 1.28–2.47). The odds of viral suppression were significantly lower among those not retained in care (AOR: 0.45; CI: 0.35–0.58). Conclusion Tailored interventions should be developed to improve viral suppression among adolescents on ART.

Abstract
Characterizing HIV acquisition modes among adolescents with HIV (AHIV) enrolling in care during adolescence is a challenging gap that impacts differential interventions. We explored whether primary data collection with targeted questionnaires may address this gap and improve understanding of risk factors and perceptions about adolescents’ HIV acquisition, in Kenyan AHIV entering care at ≥10 years, and their mothers with HIV (MHIV). Clinical data were derived through chart review. Among 1073 AHIV in care, only 26 (2%) met eligibility criteria of being ≥10 years at care enrollment, disclosed to, and with living MHIV. Among 18/26 AHIV-MHIV dyads enrolled (median age of AHIV 14 years), none had documented HIV acquisition modes. Data suggested perinatal infection in 17/18 AHIV, with 1 reported non-perinatal acquisition risk factor, and some discordance between adolescent-mother perceptions of HIV acquisition. In this difficult-to-enroll, vulnerable population of AHIV-MHIV dyads, primary data collection can enhance understanding of AHIV acquisition modes.

Predictors and consequences of HIV status disclosure to adolescents living with HIV in Eastern Cape, South Africa: a prospective cohort study. J Int AIDS Soc 2022; 25:e25910. [PMID: 35543100 PMCID: PMC9092159 DOI: 10.1002/jia2.25910] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Accepted: 04/26/2022] [Indexed: 11/18/2022] Open
Abstract
INTRODUCTION The World Health Organization recommends full disclosure of HIV-positive status to adolescents who acquired HIV perinatally (APHIV) by age 12. However, even among adolescents (aged 10-19) already on antiretroviral therapy (ART), disclosure rates are low. Caregivers often report the child being too young and fear of disclosure worsening adolescents' mental health as reasons for non-disclosure. We aimed to identify the predictors of disclosure and the association of disclosure with adherence, viral suppression and mental health outcomes among adolescents in sub-Saharan Africa. METHODS Analyses included three rounds (2014-2018) of data collected among a closed cohort of adolescents living with HIV in Eastern Cape, South Africa. We used logistic regression with respondent random-effects to identify factors associated with disclosure, and assess differences in ART adherence, viral suppression and mental health symptoms between adolescents by disclosure status. We also explored differences in the change in mental health symptoms and adherence between study rounds and disclosure groups with logistic regression. RESULTS Eight hundred and thirteen APHIV were interviewed at baseline, of whom 769 (94.6%) and 729 (89.7%) were interviewed at the second and third rounds, respectively. The proportion aware of their HIV-positive status increased from 63.1% at the first round to 85.5% by the third round. Older age (adjusted odds ratio [aOR]: 1.27; 1.08-1.48) and living in an urban location (aOR: 2.85; 1.72-4.73) were associated with disclosure between interviews. There was no association between awareness of HIV-positive status and ART adherence, viral suppression or mental health symptoms among all APHIV interviewed. However, among APHIV not aware of their status at baseline, adherence decreased at the second round among those who were disclosed to (N = 131) and increased among those not disclosed to (N = 151) (interaction aOR: 0.39; 0.19-0.80). There was no significant difference in the change in mental health symptoms between study rounds and disclosure groups. CONCLUSIONS Awareness of HIV-positive status was not associated with higher rates of mental health symptoms, or lower rates of viral suppression among adolescents. Disclosure was not associated with worse mental health. These findings support the recommendation for timely disclosure to APHIV; however, adherence support post-disclosure is important.

Abstract
INTRODUCTION South Africa's progress towards the 95-95-95 goals has been significantly slower among adolescents living with HIV (ALHIV), among whom antiretroviral therapy (ART) adherence, retention in care and viral suppression remain a concern. After 2 years of living with COVID-19, it is important to examine the direct and indirect effects of the pandemic on healthcare resources, access to HIV services and availability of support structures, to assess their impact on HIV care for ALHIV. DISCUSSION The COVID-19 response in South Africa has shifted healthcare resources towards combatting COVID-19, affecting the quality and availability of HIV services-especially for vulnerable populations, such as ALHIV. The healthcare system's response to COVID-19 has threatened to diminish fragile gains in engaging ALHIV with HIV services, especially as this group relies on overburdened public health facilities for their HIV care. Reallocation of limited health resources utilized by ALHIV disrupted healthcare workers' capacity to form and maintain therapeutic relationships with ALHIV and monitor ALHIV for ART-related side effects, treatment difficulties and mental health conditions, affecting their ability to retain ALHIV in HIV care. Prevailing declines in HIV surveillance meant missed opportunities to identify and manage opportunistic infections and HIV disease progression in adolescents. "Lockdown" restrictions have limited access to healthcare facilities and healthcare workers for ALHIV by reducing clinic appointments and limiting individual movement. ALHIV have had restricted access to social, psychological and educational support structures, including national feeding schemes. This limited access, coupled with reduced opportunities for routine maternal and sexual and reproductive health services, may place adolescent girls at greater risk of transactional sex, child marriages, unintended pregnancy and mother-to-child HIV transmission. CONCLUSIONS Adolescent HIV care in South Africa is often overlooked; however, ART adherence among ALHIV in South Africa is particularly susceptible to the consequences of a world transformed by COVID-19. The current structures in place to support HIV testing, ART initiation and adherence have been reshaped by disruptions to health structures, new barriers to access health services and the limited available education and psychosocial support systems. Reflecting on these limitations can drive considerations for minimizing these barriers and retaining ALHIV in HIV care.

Abstract
Adolescents living with HIV (ALHIV) struggle to remain engaged in HIV-related care and adhere to antiretroviral treatment (ART) due to a myriad of physical, psychological and cognitive-developmental challenges. We report on the profile of ALHIV aged 10-19 years on ART and the clinical factors associated with their retention in care. A retrospective cohort analysis was conducted with 16,108 ALHIV, aged 10-19 years, who were enrolled in 136 ART clinics in the Ehlanzeni district. Anonymised data were obtained from electronic medical records (Tier.net). Trends in retention in care among adolescents on ART was described using Kaplan-Meier survival estimates. Cox proportional analysis was performed to identify factors associated with retention in care over 2 years. More than half (53%) were females, and median duration on ART was 8 months. Retention in care among adolescents at months 6, 12, 18 and 24 was 90.5%, 85.4%, 80.8% and 76.2%, respectively. After controlling for confounders, risk of dying or lost to follow up increased for female adolescents (aHR = 1.28, 95% CI 1.10-1.49); being initiated on ART while pregnant (aHR = 2.72, 95% CI 1.99-3.69); history of TB infection (aHR = 1.71, 95% CI 1.10-2.65); and started ART at age 10-14 years (aHR = 2.45, 95% CI 1.96-3.05), and 15-19 years (aHR = 9.67, 95% CI 7.25-12.89). Retention in care among adolescents on ART over two-year period was considerably lower than the UNAIDS 2030 target of 95%. Of particular concern for intervention is the lower rates of retention in care among females and pregnant adolescents and starting ART between the ages of 10 and 19 years. Family or caregivers and peer support groups centred interventions designed to promote early initiation and retention in care through early case identification are needed.

Abstract
The underlying molecular mechanism and their general effect on the replication capacity of HIV 1 drug-resistance-associated mutations is often poorly understood. To elucidate the effect of two such mutations located in a region with a high density of spicing regulatory elements on the HIV-1-splicing outcome, bioinformatic predictions were combined with transfection and infection experiments. Results show that the previously described R263K drug-resistance-associated integrase mutation has additionally a severe effect on the ESE2b splicing regulatory element (SRE) in exon 2b, which causes loss of SD2b recognition. This was confirmed by an R263R silent mutation with a similar predicted effect on the exon 2b SRE. In contrast, a V260I mutation and its silent counterpart with a lower effect on ESS2b did not exhibit any differences in the splicing pattern. Since HIV-1 highly relies on a balanced splicing reaction, changes in the splicing outcome can contribute to changes in viral replication and might add to the effect of escape mutations toward antiviral drugs. Thus, a classification of mutations purely addressing proteins is insufficient.

Abstract
Supplemental Digital Content is Available in the Text. Background: Intimate partner violence (IPV) may affect the HIV-treatment cascade. Setting: Four high HIV-prevalence DREAMS health districts in South Africa. Methods: Secondary analysis of cross-sectional data collected March 2017–June 2018, using random household sample of young (12–24 years) girls and women. Face-to-face interviews assessed IPV and HIV-status knowledge, and finger-prick blood draws assessed ART (antiretroviral therapy) uptake and viral suppression. We used logistic regression to estimate crude and adjusted effects of IPV on HIV knowledge, ART uptake, and viral suppression. Results: Of 18,230 adolescent girls and young women, 8413 (46%) reported ever having had sex, of whom 1118 (13%) were HIV positive. The 90:90:90 benchmarks were 61% knew their status, 86% had ART present in their blood sample, and 91% were virally suppressed. Among the entire sample of young women living with HIV, 65.6% were virally suppressed. Past year IPV was reported by 15%. In adjusted models, IPV trended toward increasing the odds that a young woman was aware she was living with HIV [adjusted odds ratios (aOR) = 1.40, 2.00–9.98, P = 0.067]. There was no association between IPV and reduced treatment use (aOR = 0.73, 0.41–1.29). IPV was independently associated with reduced viral suppression (aOR = 0.30, 0.13–0.66). Conclusions: Addressing the role of IPV in undermining the treatment cascade for adolescent and young women is a critical issue for HIV programming.

Abstract
OBJECTIVE To determine the spectrum of cancers in adolescents and young adults (AYAs) living with and without HIV in South Africa. DESIGN Cross-sectional study with cancer records provided by the National Cancer Registry (NCR) and HIV records from the National Health Laboratory Service (NHLS). SETTING AND PARTICIPANTS The NHLS is the largest provider of pathology services in the South African public sector. The NCR is a division of the NHLS. We included AYAs (aged 10-24 years) diagnosed with cancer by public health sector laboratories between 2004 and 2014 (n=8479). HIV status was obtained through record linkages and text mining. PRIMARY AND SECONDARY OUTCOMES We determined the spectrum of cancers by HIV status in AYAs. We used multivariable logistic regression to describe the association of cancer in AYAs with HIV, adjusting for age, sex, ethnicity and calendar period. We imputed (post hoc) the HIV status for AYA with unknown HIV status. RESULTS 8479 AYAs were diagnosed with cancer, HIV status was known for 45% (n=3812). Of those whose status was known, about half were HIV positive (n=1853). AYAs living with HIV were more likely to have Kaposi's sarcoma (adjusted OR (aOR) 218, 95% CI 89.9 to 530), cervical cancer (aOR 2.18, 95% CI 1.23 to 3.89), non-Hodgkin's lymphoma (aOR 2.12, 95% CI 1.69 to 2.66) and anogenital cancers other than cervix (aOR 2.73, 95% CI 1.27 to 5.86) than AYAs without HIV. About 44% (n=1062) of AYAs with HIV-related cancers had not been tested for HIV. CONCLUSIONS Targeted HIV testing for AYAs diagnosed with cancer, followed by immediate start of antiretroviral therapy, screening for cervical precancer and vaccination against human papilloma virus is needed to decrease cancer burden in AYAs living with HIV in South Africa.

Abstract
BACKGROUND Literature on cancer in adolescents and young adults (AYA; aged 15-24 years) living with HIV is scarce. We studied cancer incidence in AYA living with HIV in South Africa between 2004 and 2014. METHODS In this nationwide cohort study, we included individuals between 15 and 24 years old who had at least two HIV-related laboratory measurements on separate days between Jan 1, 2004, and Dec 31, 2014, recorded in the National Health Laboratory Service database. We used privacy-preserving probabilistic record linkage methods to identify HIV-related laboratory records that most likely belonged to the same individual and to then link these individuals to cancer diagnoses from the National Cancer Registry. We computed incidence rates for the most common cancers in AYA living with HIV, and we assessed associations between these cancers and sex, age, calendar year, and CD4 cell count using Cox proportional hazards models and adjusted hazard ratios (aHRs). FINDINGS We included 782 454 AYA living with HIV (698 066 [89·2%] women) with 1 428 114 person-years of follow-up. Of those, 867 developed incident cancer (incidence rate 60·7 per 100 000 person-years), including 429 who developed Kaposi sarcoma (30·0 per 100 000 person-years), 107 non-Hodgkin lymphoma (7·5 per 100 000 person-years), 48 Hodgkin lymphoma (3·4 per 100 000 person-years), 45 cervical cancer (3·4 per 100 000 woman-years), and 32 leukaemia (2·2 per 100 000 person-years). Kaposi sarcoma was more common in the 20-24 year age group than the 15-19 year age group (aHR 1·39, 95% CI 1·03-1·86). Male sex was associated with higher rates of Kaposi sarcoma (2·06, 1·61-2·63), non-Hodgkin lymphoma (3·17, 2·06-4·89), Hodgkin lymphoma (4·83, 2·61-8·93), and leukaemia (unadjusted HR 5·90, 95% CI 2·87-12·12). Cancer rates decreased over the study period, driven by declining Kaposi sarcoma rates. Lower baseline CD4 cell counts were associated with higher rates of Kaposi sarcoma, cervical cancer, non-Hodgkin lymphoma, and Hodgkin lymphoma, but not leukaemia. INTERPRETATION Infection-related cancers were the most common cancer types in AYA living with HIV in South Africa, and their incidence rates increased with lower CD4 cell counts. Therefore, innovative strategies to maintaining high CD4 cell counts are needed to reduce the cancer burden in this vulnerable population.

Abstract
BACKGROUND Few studies have evaluated tuberculosis control in children and adolescents. We used routine tuberculosis surveillance data to quantify age- and human immunodeficiency virus (HIV)-stratified trends over time and investigate the relationship between tuberculosis, HIV, age, and sex. METHODS All children and adolescents (0-19 years) routinely treated for drug-susceptible tuberculosis in South Africa and recorded in a de-duplicated national electronic tuberculosis treatment register (2004-2016) were included. Age- and HIV-stratified tuberculosis case notification rates (CNRs) were calculated in four age bands: 0-4, 5-9, 10-14, and 15-19 years. The association between HIV infection, age, and sex in children and adolescents with tuberculosis was evaluated using multivariable logistic regression. RESULTS Of 719 400 children and adolescents included, 339 112 (47%) were 0-4 year olds. The overall tuberculosis CNR for 0-19 year olds declined by 54% between 2009 and 2016 (incidence rate ratio [IRR] = 0.46; 95% confidence interval [CI], .45-.47). Trends varied by age and HIV, with the smallest reductions (2013-2016) in HIV-positive 0-4 year olds (IRR = 0.90; 95% CI, .85-.95) and both HIV-positive (IRR = .84; 95% CI, .80-.88) and HIV-negative (IRR = 0.89; 95% CI, .86-.92) 15-19 year olds. Compared with 0- to 4-year-old males, odds of HIV coinfection among 15-19 year olds were nearly twice as high in females (adjusted odds ratio [aOR] = 2.49; 95% CI, 2.38-2.60) than in males (aOR = 1.35; 95% CI, 1.29-1.42). CONCLUSIONS South Africa's national response to the HIV epidemic has made a substantial contribution to the observed declining trends in tuberculosis CNRs in children and adolescents. The slow decline of tuberculosis CNRs in adolescents and young HIV-positive children is concerning. Understanding how tuberculosis affects children and adolescents beyond conventional age bands and by sex can inform targeted tuberculosis control strategies.

Abstract
Adolescents living with HIV comprise a significant patient population in sub Saharan Africa but are poorly retained in care with consequent increased mortality and morbidity. We conducted in-depth interviews with 25 adolescents living with HIV engaged in care from five clinics in Johannesburg regarding their recommendations for the healthcare system. Findings included advocating for adolescent clinics, recognizing the importance of clinic-based support groups, valuing the influence lay counselors have in providing healthcare to adolescents, improving widespread education of vertical HIV transmission and meaningfully linking clinics to the community. Our study offers guidance to the differentiated care model recommended for adolescent treatment highlighting that a positive youth development approach and use of lay and peer counselors may act as cornerstones of this model. Serving the mental health needs of adolescents living with HIV in a responsive manner may strengthen their use of the system and elevate it to a source of resilience.

Abstract
In South Africa, caregivers and healthcare workers (HCWs) lack confidence and skills to disclose to children with perinatal HIV (PHIV). Moreover, existing disclosure guidelines do not provide strategies on how to approach disclosure. Although the caregiver has been endorsed as a responsible person to disclose to the child, the involvement of HCWs in the process is critical. Yet research suggests that many HCWs are reluctant to perform disclosure. This study examines the involvement in, practices of, and barriers against HCWs’ disclosing to children with PHIV.

Reaching underserved South Africans with integrated chronic disease screening and mobile HIV counselling and testing: A retrospective, longitudinal study conducted in Cape Town. PLoS One 2021; 16:e0249600. [PMID: 33945540 PMCID: PMC8096085 DOI: 10.1371/journal.pone.0249600] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Accepted: 03/20/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Community-based, mobile HIV counselling and testing (HCT) and screening for non-communicable diseases (NCDs) may improve early diagnosis and referral for care in underserved populations. We evaluated HCT/NCD data and described population characteristics of those visiting a mobile clinic in high HIV disease burden settings in Cape Town, South Africa, between 2008 and 2016. METHODS Trained counsellors registered patients ≥12 years old at a mobile clinic, which offered HCT and blood pressure, diabetes (glucose testing) and obesity (body mass index) screening. A nurse referred patients who required HIV treatment or NCD care. Using multivariable logistic regression, we estimated correlates of new HIV diagnoses adjusting for gender, age and year. RESULTS Overall, 43,938 individuals (50% male; 29% <25 years; median age = 31 years) tested for HIV at the mobile clinic, where 27% of patients (66% of males, 34% of females) reported being debut HIV testers. Males not previously tested for HIV had higher rates of HIV positivity (11%) than females (7%). Over half (55%, n = 1,343) of those previously diagnosed HIV-positive had not initiated ART. More than one-quarter (26%) of patients screened positive for hypertension (males 28%, females 24%, p<0.001). Females were more likely overweight (25% vs 20%) or obese (43% vs 9%) and presented with more diabetes symptoms than males (8% vs 4%). Females (3%) reported more symptoms of STIs than males (1%). Reporting symptoms of sexually transmitted infections (aOR = 3.45, 95% CI = 2.84, 4.20), diabetes symptoms (aOR = 1.61, 95% 1.35, 1.92), and TB symptoms (aOR = 4.40, 95% CI = 3.85, 5.01) were associated with higher odds of a new HIV diagnosis after adjusting for covariates. CONCLUSION Findings demonstrate that mobile clinics providing integrated HCT and NCD screening may offer the opportunity of early diagnosis and referral for care for those who delay screening, including men living with HIV not previously tested.

Abstract
Background Antenatal care (ANC) clinics remain important entry points to HIV care for pregnant women living with HIV—including adolescents. Prior knowledge of their HIV status at ANC enrollment is crucial to providing services for prevention of mother-to-child transmission (PMTCT) of HIV. We examined known HIV status of pregnant adolescents and women in other age groups at ANC enrollment. Methods A descriptive study of routinely reported PMTCT data from 419 facilities in Eswatini, Ethiopia, and Mozambique, from January through December 2018 was conducted. We assessed knowledge of HIV status by country for three age groups: adolescents aged 15–19 years, young women aged 20–24 years, and older women aged 25–49 years. We report HIV prevalence and proportions of known and newly diagnosed HIV infections in women, by age group and country. The data were summarized by frequencies and proportions, including their 95% confidence intervals. Results Among the facilities examined, 52 (12.4%) were in Eswatini, 63 (15.0%) in Ethiopia, and 304 (72.6%) in Mozambique. Across three countries, 488,121 women attended a first ANC visit and 23,917 (4.9%) were HIV-positive. Adolescents constituted 22% of all ANC attendees, whereas young and older women represented 33% and 45%, respectively. HIV prevalence was lowest among adolescents than in other age groups in Eswatini (adolescents 11.9%, young 24.2% and older 47.3%), but comparable to young women in Ethiopia (adolescents 1.6%, young 1.6% and older 2.2%) and Mozambique (adolescents 2.5%, young 2.5% and older 5.8%), However, in each of the three countries, lower proportions of adolescents knew their HIV-positive status before ANC enrollment compared to other age groups: in Eswatini (adolescents 51.3%, young 59.9% and older 79.2%), in Ethiopia (adolescents 42.9%, young 63.7% and older 75.2%), and in Mozambique (adolescents 16.4%, young 33.2% and older 45.6%). Conclusion Overall, adolescents made up nearly one-quarter of the women examined and had the least knowledge of their HIV status at ANC enrollment. Their HIV prevalence and known HIV-positive status varied widely across the countries examined. Adolescent-friendly sexual and reproductive health, and PMTCT services, before pregnancy, are needed to improve knowledge of HIV status and support pregnant adolescents and their infants. Plain English summary Antenatal care (ANC) clinics are important for HIV testing of pregnant adolescents, who may not know their HIV-positive status at the first ANC visit. We describe data on pregnant adolescents and women in other age groups in ANC services to examine their prior HIV status at ANC enrollment across three African countries. We examined data from 419 PMTCT sites in Eswatini, Ethiopia, and Mozambique from January-December 2018, to evaluate HIV testing results for adolescents, young and older women aged 15–19, 20–24 and 25–49 years, respectively. We report the number of women living with HIV and the proportions of known and newly identified women living with HIV, by age-group and country. Across three countries, 488,121 women attended ANC and 23,917 (4.9%) were living with HIV. Adolescents constituted 22% of all ANC attendees, whereas young and older women represented 33% and 45%, respectively. HIV prevalence in each country compared to other age groups was lowest and varied among adolescents from 11.9% in Eswatini, to 1.6% in Ethiopia and to 2.5% in Mozambique. Also, fewer adolescents knew their HIV-positive status before ANC enrollment compared to young and older women from 51.3% in Eswatini, 42.9% in Ethiopia to only 16.4% in Mozambique. Pregnant adolescents made up nearly one-quarter of all ANC attendees; a majority of them had no previously known HIV-positive status. Adolescent-friendly, sexual and reproductive health services, before pregnancy and in PMTCT services, are needed to support pregnant adolescents and their infants.

Abstract
BACKGROUND Adolescents living with HIV (ALHIV) 15-19 years of age are a growing proportion of all people living with HIV globally and the population includes adolescents with vertically acquired HIV (AVH) and behaviorally acquired HIV (ABH). METHODS We conducted a survey to measure sociodemographic characteristics, educational status, health history, and antiretroviral therapy (ART) adherence among a convenience sample of ALHIV at three government health facilities in 2019 in Nampula, Mozambique. ALHIV 15-19 years on ART, including females attending antenatal care, were eligible. Routine HIV care data were extracted from medical charts. Classification of ALHIV by mode of transmission was based on medical charts and survey data. ALHIV who initiated ART <15 years or reported no sex were considered AVH; all others ABH. Frequencies were compared by sex, and within sex, by mode of transmission (AVH vs. ABH) using Chi-square, Fishers exact tests and Wilcoxon rank-sum tests. RESULTS Among 208 ALHIV, 143 (69%) were female and median age was 18 years [interquartile range (IQR) 16-19]. Just over half of ALHIV (53%) were in or had completed secondary or higher levels of education; the most common reason for not being in school reported by 36% of females was pregnancy or having a child. Of all ALHIV, 122 (59%) had VL data, 62% of whom were <1000 copies/mL. Almost half (46%) of ALHIV reported missing ARVs ≥ 1 day in the past month (62% of males vs. 39% of females; p = 0.003). Just over half (58%) of ALHIV in relationships had disclosed their HIV status: 13% of males vs. 69% of females (p<0.001). Among sexually active males, 61% reported using a condom at last sex compared to 26% of females (p<0.001). Among female ALHIV, 50 (35%) were AVH and 93 (65%) were ABH, 67% of whom were not in school compared to 16% of ABH, (p<0.001). DISCUSSION Data from our study underscore the high level of deprivation among ALHIV enrolled in HIV care in Mozambique, as well as important disparities by sex and mode of transmission. These data can inform the development of effective interventions for this complex and important population.

Abstract
Despite expanded antiretroviral therapy (ART) eligibility in South Africa, many people diagnosed with HIV do not initiate ART promptly, yet understanding of the reasons is limited. Using data from an 8-month prospective cohort interview study of women and men newly-diagnosed with HIV in three public-sector primary care clinics in the eThekwini (Durban) region, South Africa, 2010-2014, we examined if theoretically-relevant social-structural, social-cognitive, psychosocial, and health status indicators were associated with time to ART initiation. Of 459 diagnosed, 350 returned to the clinic for their CD4+ test results (linkage); 153 (33.3%) were ART-eligible according to treatment criteria at the time; 115 (75.2% of those eligible) initiated ART (median = 12.86 weeks [95% CI: 9.75, 15.97] after linkage). In adjusted Cox proportional hazard models, internalized stigma was associated with a 65% decrease in the rate of ART initiation (Adjusted hazard ratio [AHR] 0.35, 95% CI: 0.19-0.80) during the period less than four weeks after linkage to care, but not four or more weeks after linkage to care, suggesting that stigma-reduction interventions implemented shortly after diagnosis may accelerate ART uptake. As reported by others, older age was associated with more rapid ART initiation (AHR for 1-year age increase: 1.04, 95% CI: 1.01-1.07) and higher CD4+ cell count (≥300μL vs. <150μL) was associated with a lower rate of initiation (AHR 0.38, 95% CI: 0.19-0.80). Several other factors that were assessed prior to diagnosis, including stronger belief in traditional medicine, higher endorsement of stigma toward people living with HIV, food insecurity, and higher psychological distress, were found to be in the expected direction of association with ART initiation, but confidence intervals were wide and could not exclude a null finding.

Rifabutin pharmacokinetics and safety among TB/HIV-coinfected children receiving lopinavir/ritonavir-containing second-line ART. J Antimicrob Chemother 2021; 76:710-717.

Abstract
BACKGROUND Treatment options are limited for TB/HIV-coinfected children who require PI-based ART. Rifabutin is the preferred rifamycin for adults on PIs, but the one study evaluating rifabutin with PIs among children was stopped early due to severe neutropenia. METHODS We evaluated rifabutin safety and plasma pharmacokinetics among coinfected children 3-15 years of age receiving rifabutin 2.5 mg/kg daily with standard doses of lopinavir/ritonavir. The AUC0-24 at 2, 4 and 8 weeks after rifabutin initiation was described using intensive sampling and non-compartmental analysis. Clinical and laboratory toxicities were intensively monitored at 12 visits throughout the study. RESULTS Among 15 children with median (IQR) age 13.1 (10.9-14.0) years and weight 25.5 (22.3-30.5) kg, the median (IQR) rifabutin AUC0-24 was 5.21 (4.38-6.60) μg·h/mL. Four participants had AUC0-24 below 3.8 μg·h/mL (a target for the population average exposure) at week 2 and all had AUC0-24 higher than 3.8 μg·h/mL at the 4 and 8 week visits. Of 506 laboratory evaluations during rifabutin, grade 3 and grade 4 abnormalities occurred in 16 (3%) and 2 (0.4%) instances, respectively, involving 9 (60%) children. Specifically, grade 3 (n = 4) and grade 4 (n = 1) neutropenia resolved without treatment interruption or clinical sequelae in all patients. One child died at week 4 of HIV-related complications. CONCLUSIONS In children, rifabutin 2.5 mg/kg daily achieved AUC0-24 comparable to adults and favourable HIV and TB treatment outcomes were observed. Severe neutropenia was relatively uncommon and improved with ongoing rifabutin therapy. These data support the use of rifabutin for TB/HIV-coinfected children who require lopinavir/ritonavir.

Haghighat R, Toska E, Bungane N, Cluver L. The HIV care cascade for adolescents initiated on antiretroviral therapy in a health district of South Africa: a retrospective cohort study. BMC Infect Dis 2021; 21:60. [PMID: 33435861 PMCID: PMC7805141 DOI: 10.1186/s12879-020-05742-9] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Accepted: 12/27/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Little evidence exists to comprehensively estimate adolescent viral suppression after initiation on antiretroviral therapy in sub-Saharan Africa. This study examines adolescent progression along the HIV care cascade to viral suppression for adolescents initiated on antiretroviral therapy in South Africa. METHODS All adolescents ever initiated on antiretroviral therapy (n=1080) by 2015 in a health district of the Eastern Cape, South Africa, were interviewed in 2014-2015. Clinical records were extracted from 52 healthcare facilities through January 2018 (including records in multiple facilities). Mortality and loss to follow-up rates were corrected for transfers. Predictors of progression through the HIV care cascade were tested using sequential multivariable logistic regressions. Predicted probabilities for the effects of significant predictors were estimated by sex and mode of infection. RESULTS Corrected mortality and loss to follow-up rates were 3.3 and 16.9%, respectively. Among adolescents with clinical records, 92.3% had ≥1 viral load, but only 51.1% of viral loads were from the past 12 months. Adolescents on ART for ≥2 years (AOR 3.42 [95%CI 2.14-5.47], p< 0.001) and who experienced decentralised care (AOR 1.39 [95%CI 1.06-1.83], p=0.018) were more likely to have a recent viral load. The average effect of decentralised care on recent viral load was greater for female (AOR 2.39 [95%CI 1.29-4.43], p=0.006) and sexually infected adolescents (AOR 3.48 [95%CI 1.04-11.65], p=0.043). Of the total cohort, 47.5% were recorded as fully virally suppressed at most recent test. Only 23.2% were recorded as fully virally suppressed within the past 12 months. Younger adolescents (AOR 1.39 [95%CI 1.06-1.82], p=0.017) and those on ART for ≥2 years (AOR 1.70 [95%CI 1.12-2.58], p=0.013) were more likely to be fully viral suppressed. CONCLUSIONS Viral load recording and viral suppression rates remain low for ART-initiated adolescents in South Africa. Improved outcomes for this population require stronger engagement in care and viral load monitoring.

Abstract
BACKGROUND The advent of resistance-associated mutations in HIV-1 is a barrier to the success of the ARTs. OBJECTIVE In this study, the abundance of HIV-1 infection in Iranian children, and also detection of the TDR in naïve HIV-1 infected pediatric (under 12 years old) were evaluated. MATERIALS From June 2014 to January 2019, a total of 544 consecutive treatment-naïve HIV-1- infected individuals enrolled in this study. After RNA extraction, amplification, and sequencing of the HIV-1 pol gene, the DRM and phylogenetic analysis were successfully performed on the plasma specimens of the ART-naïve HIV-1-infected-children under 12 years old. The DRMs were recognized using the Stanford HIV Drug Resistance Database. RESULTS Out of the 544 evaluated treatment-naïve HIV-1-infected individuals, 15 (2.8%) cases were children under 12 years old. The phylogenetic analyses of the amplified region of pol gene indicated that all of the 15 HIV-1-infected pediatric patients were infected by CRF35_AD, and a total of 13.3% (2/15) of these children were infected with HIV-1 variants with SDRMs (one child harbored two related SDRMs [D67N, V179F], and another child had three related SDRMs [M184V, T215F, and K103N]), according to the last algorithm of the WHO. No PIs-related SDRMs were observed in HIV-1-infected children. CONCLUSION The current study demonstrated that a total of 13.3% of treatment-naïve HIV-1-infected Iranian pediatrics (under 12 years old) were infected with HIV-1 variants with SDRMs. Therefore, it seems that screening to recognize resistance-associated mutations before the initiation of ARTs among Iranian children is essential for favorable medication efficacy and dependable prognosis.

Abstract
In South Africa, despite universal antiretroviral therapy (ART) availability, 60% of persons living with HIV (PLWH) ages 15-24 are not on treatment. This qualitative study aimed to identify barriers to ART initiation and the implications for a proposed community-based Youth Treatment Club to improve ART initiation for young PLWH in limited-resource, high HIV-prevalence communities in Cape Town, South Africa. Recruiting participants at community testing sites from 2018 to 2019, we conducted semi-structured interviews, informed by Social Action Theory (SAT), with 20 young adults, ages 18- to 24-years-old, newly diagnosed with HIV, along with 10 healthcare providers. Through systematic qualitative analysis, we found that young PLWH face barriers to treatment initiation in three SAT domains: (1) stigmatizing social norms (social regulation processes); (2) challenges coping with a new diagnosis (self-regulation processes); and (3) anticipated stigma in the clinic environment (contextual factors). Participants shared that a proposed community-based Youth Treatment Club for newly diagnosed youth would be an acceptable strategy to promote ART initiation. They emphasized that it should include supportive peers, trained facilitator support for counseling and education, and a youth-friendly environment.

Maseko Y, Madiba S. Pain, Anger, and the Fear of Being Discovered Persist Long after the Disclosure of HIV Serostatus among Adolescents with Perinatal HIV in Rural Communities in South Africa. CHILDREN (BASEL, SWITZERLAND) 2020; 7:E261. [PMID: 33260717 PMCID: PMC7761479 DOI: 10.3390/children7120261] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Revised: 11/20/2020] [Accepted: 11/26/2020] [Indexed: 12/30/2022]
Abstract
Informing adolescents of their HIV serostatus forms part of their HIV care and is a critical step in the transition to adult clinical care services. This article describes the experiences of adolescents with perinatal HIV in regard to disclosure, and examines the impact disclosure has on their emotional health and behaviors. We used a qualitative design to conduct interviews with 21 adolescents aged 12-19 years recruited from a rural district in South Africa. NVivo 10 computer software was used for thematic analyses. All adolescents were aware of their HIV-serostatus. The findings show that delayed disclosure, was a one-time event, and was unplanned. Disclosure occurred at the clinic rather than the adolescent's home. For most adolescents, feelings of anger, pain, sadness, negative perceptions of self, internalized stigma, and denial persisted long after disclosure occurred. They lived in constant fear of having their serostatus being discovered, and they developed a sense of fear of self-disclosure. Their negative emotions undermined treatment adherence. In contrast, other adolescents that described disclosure as a positive event, had accepted their HIV status, and lived similar to other adolescents. The prolonged negative reactions underscore the importance of ongoing post-disclosure interventions for adolescents in rural settings where psychosocial support services are insufficient to address their emotional wellbeing.

Abstract
OBJECTIVE To determine rates of retention and viral suppression among adolescents living with perinatally-acquired HIV who remained in pediatric care compared to those who transitioned to adult care. METHODS We evaluated a natural experiment involving adolescents living with perinatally-acquired HIV who were attending a government-supported antiretroviral clinic in KwaZulu-Natal, South Africa. Prior to 2011, all adolescents transitioned to adult care at 12 years of age. Due to a policy change, all adolescents were retained in pediatric care after 2011. We analyzed adolescents two years before and two years after this policy change. Outcomes were retention in care and HIV viral suppression one year after transition to adult care or the 13th birthday if remaining in pediatric care. RESULTS In the natural experiment, 180 adolescents who turned 12 years old between 2011 and 2014 were evaluated; 35 (20%) transitioned to adult care under the old policy and 145 (80%) remained in pediatric care under the new policy. Adolescents who transitioned to the adult clinic had lower rates of retention in care (49%; 17/35) compared to adolescents remaining in the pediatric clinic (92%; 134/145; p<0.001). Retention in care was lower (ARR 0.59; 95%CI 0.43-0.82; p = 0.001) and viral suppression was similar (ARR = 1.06, 95%CI 0.89-1.26; p = 0.53) for adolescents who transitioned to adult care compared to adolescents remaining in pediatric care. CONCLUSION Adolescents living with perinatally-acquired HIV appear to have higher retention in care when cared for in pediatric clinics compared to adult clinics. Longer-term follow-up is needed to fully assess viral suppression.

Abstract
In spite of the high HIV burden and high prevalence and incidence of HIV infection among adolescent girls and young women (AGYW) in South Africa, uptake of HIV testing in this population falls short of the UNIADS 90-90-90 targets, leading to late diagnosis, late entry into HIV care and treatment, and poor uptake of prevention services. There is a critical need to update and deepen our understanding of attitudes towards testing in this population, in order to appropriately respond to their specific needs. This article reports on findings from an exploration of perceptions of HIV testing and testing behaviour amongst AGYW in South Africa using a combination of quantitative and qualitative data. Analysis included data on testing behaviour and reasons for never testing from a survey conducted with 4 399 AGYW aged 15-24 years in six provinces. Combined with survey data is qualitative analysis from 63 in-depth interviews and 24 focus group discussions with 237 AGYW from five provinces. Findings revealed complex, dualistic and often contradictory views towards HIV testing in this population, with fear of HIV and the consequences of testing positive existing alongside a lack of concern towards HIV infection because of the availability and accessibility of antiretrovirals. These findings can help to address barriers to HIV testing in this population and ensure appropriateness of future interventions and HIV messaging.

Abstract
The appropriateness of the paradigm underlying competency frameworks and their specific application in the list of definitions developed by a Task Group of Society for Community Research and Action (SCRA) for US community psychologists need further consideration. This paper considers the technicist and behavioural roots of some of these concepts, illustrating tensions when applying them to community psychology. It then proposes a competency perspective from the global South. Drawing from focus group discussions with, and written reflections from, postgraduate Master's students in training as clinical and counselling psychologists, this paper builds inductively from the recorded data. Following a template analysis of the material, four integrating themes were evident. The distinctive nature of community psychology is highlighted through the themes: relational foundations, activity evolution, self-management and the awareness and influences of processes. Proposals for an alternative framework ("RASP") are based on its emergence from the applications of learning to practice, emphasising community-based principles. The importance of reflection as the basis for the learning is highlighted. The imperatives to foreground social justice and to enable reflexive thinking on action are discussed, along with concepts based on Humanist and Social Constructivist paradigms, to lead to more interactive and inclusive processes in work on competencies.

Abstract
BACKGROUND Long-term retention of adolescents aged 10 -19 years on antiretroviral therapy (ART) is crucial to achieve viral load suppression. However, it is reported globally that adolescents have lower retention in care (RiC) on ART, compared with children and adults. OBJECTIVES To determine the prevalence and predictors of RiC of adolescents over 2 years following initiation onto ART in public health facilities in the Metropole District Health Services of the Western Cape province in 2013. METHODS Data of 220 adolescent patients who were newly initiated on ART in 2013 were extracted from the provincial electronic database, and subjected to univariate and bivariate analyses using SPSS. RESULTS The rate of RiC post-initiation was low throughout the study period, that is, 68.6%, 50.5% and 36.4% at 4, 12 and 24 months, respectively. The corresponding post-initiation viral load suppression levels on ART of those remaining in care and who had viral loads monitored were 84.1%, 77.4% and 68.8% at 4, 12 and 24 months, respectively. Retention in care after initiation on ART was higher amongst younger adolescents (10-14 years), compared with older adolescents (15-19 years). Male adolescents were significantly more likely to be retained, compared with females. Pregnant adolescents were significantly less likely to be retained compared with those who were not pregnant. CONCLUSION Key interventions are needed to motivate adolescents to remain in care, and to adhere to their treatment regimen to achieve the target of 90% viral load suppression, with specific emphasis on older and pregnant adolescents.

Abstract
Although the extensive rollout of antiretroviral (ARV) therapy resulted in a longer life expectancy for people living with human immunodeficiency virus (PLHIV), such individuals display a relatively increased occurrence of cardiovascular diseases (CVD). This health challenge stimulated significant research interests in the field, leading to an improved understanding of both lifestyle-related risk factors and the underlying mechanisms of CVD onset in PLHIV. However, despite such progress, the precise role of various risk factors and mechanisms underlying the development of HIV-mediated CVD still remains relatively poorly understood. Therefore, we review CVD onset in PLHIV and focus on 1) the spectrum of cardiovascular complications that typically manifest in such persons and 2) underlying mechanisms that are implicated in this process. Here, the contributions of such factors and modulators and underlying mechanisms are considered in a holistic and integrative manner to generate a unifying hypothesis that includes identification of the core pathways mediating CVD onset. The review focuses on the sub-Saharan African context, as there are relatively high numbers of PLHIV residing within this region, indicating that the greater CVD risk will increasingly threaten the well-being and health of its citizens. It is our opinion that such an approach helps point the way for future research efforts to improve treatment strategies and/or lifestyle-related modifications for PLHIV.
