Systematic review and meta-analysis of the adolescent HIV continuum of care in South Africa: the Cresting Wave

Longitudinal Trajectories of Antiretroviral Treatment Adherence and Associations With Durable Viral Suppression Among Adolescents Living With HIV in South Africa

BACKGROUND

Compared with other age groups, adolescents living with HIV (ALHIV) are estimated to have lower levels of adherence to antiretroviral treatment. Despite this, we lack evidence on adolescents' adherence patterns over time to inform the customization of intervention strategies.

SETTING

Eastern Cape province, South Africa.

METHODS

We analyzed data from a cohort of ALHIV (N = 1046, aged 10-19 years at baseline) recruited from 53 public health facilities. The cohort comprised 3 waves of data collected between 2014 and 2018 and routine viral load data from the National Institute for Communicable Disease data warehouse (2014-2019). Durable viral suppression was defined as having suppressed viral load (<1000 copies/mL) at ≥2 consecutive study waves. Group-based multitrajectory model was used to identify adherence trajectories using 5 indicators of self-reported adherence. Logistic regression modeling evaluated the associations between adherence trajectories and durable viral suppression.

RESULTS

Overall, 933 ALHIV (89.2%) completed all 3 study waves (55.1% female, mean age: 13.6 years at baseline). Four adherence trajectories were identified, namely, "consistent adherence" (49.8%), "low start and increasing" (20.8%), "gradually decreasing" (23.5%), and "low and decreasing" (5.9%). Adolescents experiencing inconsistent adherence trajectories were more likely to be older, live in rural areas, and have sexually acquired HIV. Compared with the consistent adherence trajectory, the odds of durable viral suppression were lower among adolescents in the low start and increasing (adjusted odds ratio [aOR]: 0.62, 95% CI: 0.41 to 0.95), gradually decreasing (aOR: 0.40, 95% CI: 0.27 to 0.59), and the low and decreasing adherence (aOR: 0.25, 95% CI: 0.10 to 0.62) trajectories.

CONCLUSIONS

Adherence to antiretroviral treatment remains a challenge among ALHIV in South Africa. Identifying adolescents at risk of nonadherence, based on their adherence trajectories may inform the tailoring of adolescent-friendly support strategies.

Policies and Practices Facilitating Access to and Uptake of HIV Testing Services among Adolescents in Sub-Sahara Africa: A Narrative Review

PURPOSE OF REVIEW

Expanding access to HIV testing services and linking newly diagnosed positive adolescents to antiretroviral therapy is critical to epidemic control. However, testing coverage and treatment initiation rates continue to lag behind adult counterparts. This article synthesizes evidence on facilitative policies and service delivery practices focused on adolescents to inform programming.

RECENT FINDINGS

Our narrative review found that national policies are growing more adolescent-inclusive but barriers around the age of consent, waiver frameworks and dissemination constrain translate into practice. Facility-based provider-initiated testing through integrated sexual health services and dedicated youth centres demonstrates uptake effectiveness if confidentiality and youth-friendly adaptations are assured. Supportive policies, youth-responsive adaptations across testing models and strengthening age-disaggregated monitoring are vital to improving adolescents' engagement across the HIV testing and treatment cascade. Further implementation research is imperative to expand the reach of adolescent HIV testing in sub-Saharan Africa.

Pathways between adverse childhood experiences and viral suppression among male HIV-infected adolescents in South Africa

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.

A comparison of the surgical outcomes of ventriculoperitoneal versus lumbar peritoneal shunts in the management of intracranial hypertension secondary to cryptococcal meningitis in HIV infected adult patients

OBJECTIVE

Cryptococcal meningitis (CM), an AIDS-defining illness, significantly impacts morbidity and mortality. This study aims to compare complications arising from ventriculoperitoneal shunt (VPS) and lumbar peritoneal shunt (LPS) procedures used to manage refractory intracranial hypertension (IH) secondary to CM in HIV-infected patients.

METHODS

Retrospective data were collected from January 2003 to January 2015 for HIV-infected adults diagnosed with refractory IH secondary to CM and subsequently shunted. Demographics, clinical characteristics, antiretroviral therapy, laboratory findings (including CD4 count and CSF results), CT brain scan results, shunt-related complications, and mortality were compared between VPS and LPS groups.

RESULTS

This study included 83 patients, with 60 (72%) undergoing VPS and 23 (28%) receiving LPS. Mean ages were comparable between VPS (32.5) and LPS (32.2) groups (p = 0.89). Median CD4+ counts were 76 cells/µl (IQR= 30-129) in VPS versus 54 cells/µl (IQR= 31-83) in LPS (p=0.45). VPS group showed a higher mean haemoglobin of 11.5 g/dl compared to 9.9 g/dl in the LPS group (p=0.001). CT brain scans showed hydrocephalus in 55 VPS and 13 LPS patients respectively. Shunt complications were observed in 17 (28%) VPS patients versus 10 (43.5%) LPS patients (p=0.5). Patients developing shunt sepsis in the VPS group exhibited a median CD4+ count of 117 cells/µl (IQR= 76-129) versus 48 cells/µl (IQR= 31- 66) in the LPS group (p=0.03). Early shunt malfunction occurred more frequently in the LPS group compared to VPS group (p=0.044). The mean hospital stay was 6.2 days for VPS versus 5.4 days for LPS patients (p=0.9). In-hospital mortality was 6%, occurring in three VPS and two LPS patients respectively.

CONCLUSION

Shunting procedures remain important surgical interventions for refractory IH secondary to HIV-related CM. However, cautious consideration is warranted for patients with CD4 counts below 200 cells/µL due to increased shunt complications. This study suggests a trend toward higher complication rates in patients undergoing LPS insertion.

Generalized and COVID related anxiety as risk factors for health outcomes among adolescents with HIV during COVID-19 in Tanzania

The COVID-19 pandemic and associated prevention strategies caused widespread interruptions to care and treatment for people living with HIV. Adolescents living with HIV (AWHIV) were particularly vulnerable to poor mental and physical health during COVID-19. We assessed the burden of generalized and COVID-19-related anxiety and associations with adherence to HIV care and treatment and viral load suppression (VLS) among AWHIV during the peak of the COVID-19 pandemic in Tanzania.

Methods

This cross-sectional study was conducted among AWHIV aged 15-19 years attending 10 clinics in Dar es Salaam from April 2022-February 2023. Study participants completed a self-administered questionnaire including Generalized Anxiety Disorder (GAD), COVID-19-related anxiety, and other psychosocial and physical health and support measures. HIV visit adherence, viral load and sociodemographic data were abstracted from patient health records.Analysis:: Multivariable (MV) quasibinomial and logistic regression models examined associations of Generalized and COVID-19-related anxiety with visit adherence and HIV virologic suppression (HIV VL < 50 copies/mL). Data were analyzed using R software.

Results

658 AWHIV (52% male) were included in this analysis. Most (86%) had been on antiretroviral treatment (ART) for at least four years, 55% attended at least 75% of their scheduled clinic visits, and 78% were HIV virologically suppressed. The median GAD and COVID-19-related anxiety scores were 2 (IQR: 0-5, and 26 (IQR: 13-43; respectively. Only 2% scored moderate-severe generalized anxiety (score 10-21). We found no significant associations between COVID-19-related anxiety or GAD and visit adherence. Higher GAD was inversely associated with VLS (adjusted odds ratio (AOR): 0.89 (95% CI 0.81, 0.98)). Female gender and higher quality of physical life were significantly associated with VLS.

Conclusion

Low levels of generalized and COVID-19 related anxiety were reported among Tanzanian AWHIV. Integrating screening and management of generalized anxiety screening into HIV care for AWHIV could improve VLS among this population.

The Acceptability, Feasibility, and Preliminary Effectiveness of a Courier HIV-Treatment Delivery and SMS Support Intervention for Young People Living With HIV in South Africa

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.

Ethical Considerations for Engaging Children and Adolescents Living with HIV in Research in African Countries: A Systematic Review

Research engaging children and adolescents living with HIV (CALWH) is critical for youth-friendly services and HIV care, and researchers need to ensure that such engagement is ethical. We conducted a systematic review to identify key ethical considerations for the engagement of CALWH in research. The review focused on primary research articles conducted in African countries that examined ethical issues in CALWH engaged in research. Ten studies met the inclusion criteria; the following seven key domains were extracted: 1) justifications for engaging CALWH in research; 2) community involvement; 3) informed consent/assent; 4) caregiver involvement; 5) perceptions of benefits; 6) perception of the risks of involvement; and 7) confidentiality. These domains can inform the ethical engagement of CALWH in research.

Effect of dolutegravir-based drug combinations on the level of medication adherence and viral load among adolescents living with HIV in resource-limited setting: a pre-post design

OBJECTIVES

The use of antiretroviral drugs among HIV-infected adolescents has been challenged with poor medication adherence, leading to an unsuppressed viral load and ultimately to drug resistance. Recently, dolutegravir has been approved for use in adolescents with HIV, but the evidence on medication adherence and viral load suppression is limited. The study determined the effect of dolutegravir-based drug regimens on the level of medication adherence and viral load among treatment-experienced adolescents.

METHODS

A longitudinal pre-post design study was done among adolescents living with HIV at a paediatrics clinic in Nigeria. Assessment of medication adherence and viral load testing was done before and at six months of transitioning to dolutegravir-based regimens. McNemar-chi-square was used to determine the effectiveness of the drug on adherence and viral load suppression. Multivariate logistic regression analysis was performed to determine the predictors of drug adherence and viral suppression.

RESULTS

The mean age of the participants was 14.7 years (SD=3.2), and 53.3 % were males. The mean duration of ART use was 10.3 years (SD=3.2). Six months after transitioning to dolutegravir, there was a significant decrease in viral load (Z=-7.947, p<0.001) and an increase in medication adherence score (Z=-7.554, p<0.001), among the treatment-experienced adolescents. Viral suppression was 13 times higher among respondents with good medication adherence as compared to those with poor medication adherence (AOR=13.24, CI=3.25-53.90).

CONCLUSIONS

Dolutegravir is effective in improving medication adherence and viral suppression among Adolescents living with HIV. Thus, the need to transition eligible adolescents to dolutegravir to sustain better treatment outcomes.

A Systematic Review of Peer Support Interventions for Adolescents Living with HIV in Sub-Saharan Africa

Despite widespread availability of life-saving antiretroviral therapy (ART) in sub-Saharan Africa, AIDS remains one of the leading causes of death among adolescents living with HIV (ALHIV) in sub-Saharan Africa. The purpose of this article was to review the state of the science regarding interventions to improve ART adherence and/or HIV care retention among ALHIV throughout sub-Saharan Africa. The primary aim of this review was to describe the impact of peer support interventions in improving treatment outcomes (i.e., ART adherence and retention in HIV care) among ALHIV in sub-Saharan Africa. The secondary aim of this review was to determine whether these interventions may be efficacious at improving mental health outcomes. We identified 27 articles that met the eligibility criteria for our review, and categorized each article based on the type of peer support provided to ALHIV-individualized peer support, group-based support, and individualized plus group-based support. Results regarding the efficacy of these interventions are mixed and most of the studies included were deemed moderate in methodological quality. Although studies evaluating group-based peer support interventions were the most common, most of these studies were not associated with retention, adherence, or mental health outcomes. More robust, fully powered studies are needed to strengthen our knowledge base regarding peer support for ALHIV.

State-of-the-Science of human papillomavirus vaccination in women with human immunodeficiency Virus: Summary of a scientific workshop

The burden of cervical cancer is disproportionately distributed globally, with the vast majority of cases occurring in low- and middle-income countries. Women with human immunodeficiency virus (HIV) (WWH) are at increased risk of human papillomavirus (HPV) infection and cervical cancer as compared to HIV-negative individuals. HPV vaccination remains a priority in regions with a high burden of cervical cancer and high HIV prevalence. With HPV vaccines becoming more accessible, optimal use beyond the initial World Health Organization-recommended target population of 9 to 14-year-old girls is an important question. In March 2022, a group of experts in epidemiology, immunology, and vaccinology convened to discuss the state-of-the-science of HPV vaccination in WWH. This report summarizes the proceedings: review of HIV epidemiology and its intersection with cervical cancer burden, immunology, HPV vaccination including reduced-dose schedules and experience with other vaccines in people with HIV (PWH), HPV vaccination strategies and knowledge gaps, and outstanding research questions. Studies of HPV vaccine effectiveness among WWH, including duration of protection, are limited. Until data from ongoing research is available, the current recommendation for WWH remains for a multi-dose HPV vaccination regimen. A focus of the discussion included the potential impact of HIV acquisition following HPV vaccination. With no data currently existing for HPV vaccines and limited information from non-HPV vaccines, this question requires further research. Implementation research on optimal HPV vaccine delivery approaches for WWH and other priority populations is also urgently needed.

Understanding the effects of universal test and treat on longitudinal HIV care outcomes among South African youth: a retrospective cohort study

INTRODUCTION

Little is known about the effects of universal test and treat (UTT) policies on HIV care outcomes among youth living with HIV (YLHIV). Moreover, there is a paucity of information regarding when YLHIV are most susceptible to disengagement from care under the newest treatment guidelines. The longitudinal HIV care continuum is an underutilized tool that can provide a holistic understanding of population-level HIV care trajectories and be used to compare treatment outcomes across groups. We aimed to explore effects of the UTT policy on longitudinal outcomes among South African YLHIV and identify temporally precise opportunities for re-engaging this priority population in the UTT era.

METHODS

Using medical record data, we conducted a retrospective cohort study among youth aged 18-24 diagnosed with HIV from August 2015-December 2018 in nine health care facilities in South Africa. We used Fine and Gray sub-distribution proportional hazards models to characterize longitudinal care continuum outcomes in the population overall and stratified by treatment era of diagnosis. We estimated the proportion of individuals in each stage of the continuum over time and the restricted mean time spent in each stage in the first year following diagnosis. Sub-group estimates were compared using differences.

RESULTS

A total of 420 YLHIV were included. By day 365 following diagnosis, just 23% of individuals had no 90-or-more-day lapse in care and were virally suppressed. Those diagnosed in the UTT era spent less time as ART-naïve (mean difference=-19.3 days; 95% CI: -27.7, -10.9) and more time virally suppressed (mean difference = 17.7; 95% CI: 1.0, 34.4) compared to those diagnosed pre-UTT. Most individuals who were diagnosed in the UTT era and experienced a 90-or-more-day lapse in care disengaged between diagnosis and linkage to care or ART initiation and viral suppression.

CONCLUSIONS

Implementation of UTT yielded modest improvements in time spent on ART and virally suppressed among South African YLHIV- however, meeting UNAIDS' 95-95-95 targets remains a challenge. Retention in care and re-engagement interventions that can be implemented between diagnosis and linkage to care and between ART initiation and viral suppression (e.g., longitudinal counseling) may be particularly important to improving care outcomes among South African YLHIV in the UTT era.

A randomized stepped wedge trial of an intensive combination approach to roll back the HIV epidemic in Nigerian adolescents: iCARE Nigeria treatment support protocol

BACKGROUND

Nigeria is one of six countries with half the global burden of youth living with HIV. Interventions to date have been inadequate as AIDS-related deaths in Nigeria's youth have remained unchanged in recent years. The iCARE Nigeria HIV treatment support intervention, a combination of peer navigation and SMS text message medication reminders to promote viral suppression, demonstrated initial efficacy and feasibility in a pilot trial among youth living with HIV in Nigeria. This paper describes the study protocol for the large-scale trial of the intervention.

METHODS

The iCARE Nigeria-Treatment study is a randomized stepped wedge trial of a combination (peer navigation and text message reminder) intervention, delivered to youth over a period of 48 weeks to promote viral suppression. Youth receiving HIV treatment at six clinical sites in the North Central and South Western regions of Nigeria were recruited for participation. Eligibility criteria included registration as a patient at participating clinics, aged 15-24 years, on antiretroviral therapy for at least three months, ability to understand and read English, Hausa, Pidgin English, or Yoruba, and intent to remain a patient at the study site during the study period. The six clinic sites were divided into three clusters and randomized to a sequence of control and intervention periods for comparison. The primary outcome is plasma HIV-1 viral load suppression, defined as viral load ≤ 200 copies/mL, in the intervention period versus the control period at 48 weeks of intervention.

DISCUSSION

Evidence-based interventions to promote viral load suppression among youth in Nigeria are needed. This study will determine efficacy of a combination intervention (peer navigation and text message reminder) and collect data on potential implementation barriers and facilitators to inform scale-up if efficacy is confirmed.

Prevalence of Micronutrient Deficiency among People Living with HIV in Selected Rural Districts of the Eastern Cape Province of South Africa

Human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) leads to immune suppression, and micronutrients play vital roles in human immune responses. Hence, this study aimed to evaluate the effects of viral load suppression in adult HIV-infected patients receiving antiretroviral therapy (ART) on micronutrient deficiency and its prevalence in selected rural districts in the Eastern Cape Province of South Africa. This cross-sectional study was conducted from February 2019 to February 2021 among 50 consenting HIV-infected patients attending community health centers within the three selected districts. The data were analysed with ArcGIS v.10.8 to create geospatial maps; the Global Positioning System (GPS) for analysis and presentation; and SPSS version 25 for inferential statistics involving the t-test and Fisher's exact test, with the level of significance set at p < 0.05. Of the 50 participants, a significant difference of p = 0.003 was observed in mean age among viral load-suppressed (42.9 ± 8.89 years) and unsuppressed (32 ± 6.3 years). In addition, significant differences in the mean viral load and CD4 counts (p < 0.05) were seen. Only iron micronutrient showed a statistically significant difference (p < 0.001) between the viral load-suppressed group (mean 14.8, SD 6.1) and the unsuppressed group (mean 8.1, SD 1.6). Of the 38 individuals from the OR Tambo district, overall micronutrient deficiency was 60.5% (13 (34.2%) deficient for zinc, 9 (23.7%) deficient for iron, 5 (13.2%) for folate, and 1 (2.63%) for vitamin D). In all three study districts, deficiencies in zinc, iron, and folate micronutrients exceeded 25%, particularly in those with an unsuppressed viral load. To address these micronutrient deficiencies, people living with HIV (PLHIV) require robust nutritional supplementation programs.

Intrapersonal predictors of internalized stigma among school going adolescents living with HIV in southwestern Uganda

We assessed the association between internalized HIV stigma, resilience, health locus of control, coping self-efficacy and empowerment among adolescents living with HIV in Uganda. We conducted a cross-sectional study between August and October 2020 among 173 adolescents aged 13-18 years attending Mbarara Regional Referral Hospital's HIV clinic. We used linear regression to determine the association between HIV stigma and intrapersonal factors adjusting for sociodemographic characteristics. The median age of the participants was 16 (IQR 3) years. There was a negative correlation between HIV stigma and resilience (β= -0.03, p < 0.001), internal health locus of control (β= -0.095, p < 0.001) and coping self-efficacy (β= -0.02, p < 0.001), while empowerment was positively correlated (β = 0.07, p < 0.001) with HIV stigma. After adjusting for the intrapersonal factors (resilience, health locus of control, coping self-efficacy and empowerment) and socio-demographic characteristics (education level and boarding school), only internal health locus of control (β=-0.044, p = 0.016) and coping self-efficacy (β=-0.015, p < 0.001) remained significantly correlated with HIV stigma. The findings suggest that interventions focusing on intrapersonal factors such as internal locus of control, empowerment and resilience may contribute towards reduction of HIV stigma among adolescents in boarding schools.

Development and validation of a prediction tool to support engagement in HIV care among young people ages 10-24 years in Kenya

INTRODUCTION

Loss to follow-up (LTFU) among adolescents and young adults living with HIV (AYALWH) is a barrier to optimal health and HIV services. We developed and validated a clinical prediction tool to identify AYALWH at risk of LTFU.

METHODS

We used electronic medical records (EMR) of AYALWH ages 10 to 24 in HIV care at 6 facilities in Kenya and surveys from a subset of participants. Early LTFU was defined as >30 days late for a scheduled visit in the last 6 months, which accounts for clients with multi-month refills. We developed a tool combining surveys with EMR ('survey-plus-EMR tool'), and an 'EMR-alone' tool to predict high, medium, and low risk of LTFU. The survey-plus-EMR tool included candidate sociodemographics, partnership status, mental health, peer support, any unmet clinic needs, WHO stage, and time in care variables for tool development, while the EMR-alone included clinical and time in care variables only. Tools were developed in a 50% random sample of the data and internally validated using 10-fold cross-validation of the full sample. Tool performance was evaluated using Hazard Ratios (HR), 95% Confidence Intervals (CI), and area under the curve (AUC) ≥ 0.7 for good performance and ≥0.60 for modest performance.

RESULTS

Data from 865 AYALWH were included in the survey-plus-EMR tool and early LTFU was (19.2%, 166/865). The survey-plus-EMR tool ranged from 0 to 4, including PHQ-9 ≥5, lack of peer support group attendance, and any unmet clinical need. High (3 or 4) and medium (2) prediction scores were associated with greater risk of LTFU (high, 29.0%, HR 2.16, 95%CI: 1.25-3.73; medium, 21.4%, HR 1.52, 95%CI: 0.93-2.49, global p-value = 0.02) in the validation dataset. The 10-fold cross validation AUC was 0.66 (95%CI: 0.63-0.72). Data from 2,696 AYALWH were included in the EMR-alone tool and early LTFU was 28.6% (770/2,696). In the validation dataset, high (score = 2, LTFU = 38.5%, HR 2.40, 95%CI: 1.17-4.96) and medium scores (1, 29.6%, HR 1.65, 95%CI: 1.00-2.72) predicted significantly higher LTFU than low-risk scores (0, 22.0%, global p-value = 0.03). Ten-fold cross-validation AUC was 0.61 (95%CI: 0.59-0.64).

CONCLUSIONS

Clinical prediction of LTFU was modest using the surveys-plus-EMR tool and the EMR-alone tool, suggesting limited use in routine care. However, findings may inform future prediction tools and intervention targets to reduce LTFU among AYALWH.

Development of "Yima Nkqo," a community-based, peer group intervention to support treatment initiation for young adults with HIV in South Africa

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).

A qualitative assessment of the perceived acceptability and feasibility of eHARTS, a mobile application for transition readiness assessment for adolescents living with HIV in South Africa

South Africa has the highest burden of adolescents living with HIV (ALHIV) in the world. The transition from pediatric to adult centered HIV care is a vulnerable period during which many clinical outcomes of ALHIV suffer. Transition readiness assessments may help ALHIV transition from pediatric to adult care to improve their health outcomes. Here, we evaluated the perceived acceptability and feasibility of a mobile health (mHealth) application, eHARTS, to determine transition readiness for ALHIV in South Africa. We conducted in-depth interviews with adolescents (n = 15) and healthcare providers (n = 15) at three government-supported hospitals in KwaZulu-Natal, South Africa. We used a semi-structured interview guide comprising of open-ended questions based on the unified theory of acceptance and use of technology. We did a thematic analysis of the data using an iterative, team-based coding approach to develop themes that were representative of the participants' perspectives on the acceptability and feasibility of eHARTS. We found that most participants found eHARTS to be acceptable because of its simplicity and lack of stigma. Participants believed eHARTS was feasible as it could easily be administered within a hospital setting and integrated into regular clinic activity without disrupting patient care. Additionally, eHARTS was found to have great utility for adolescents and healthcare providers. Clinicians saw it as a valuable tool to engage adolescents and prepare them for transition. Despite concerns that eHARTS may give adolescents a wrong impression about immediate transition, participants suggested that eHARTS be framed in an empowering way as they prepare for transition to adult care. Our data showed that eHARTS is a simple, mobile transition assessment tool with perceived acceptability and feasibility for use in HIV clinics in South Africa for ALHIV. It is particularly useful for ALHIV and transitioning to adult care as it can help identify gaps in readiness for transition.

"If they had a place to live, they would be taking medication": a qualitative study identifying strategies for engaging street-connected young people in the HIV prevention-care continuum in Kenya

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.

Impact of COVID-19 on Adolescent HIV Prevention and Treatment Services in the AHISA Network

We investigated perceived impacts of COVID-19 on the delivery of adolescent HIV treatment and prevention services in sub-Saharan Africa (SSA) by administering a survey to members of the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA) from February to April 2021. We organized COVID-19 impacts, as perceived by AHISA teams, under three themes: service interruptions, service adjustments, and perceived individual-level health impacts. AHISA teams commonly reported interruptions to prevention programs, diagnostic testing, and access to antiretroviral therapy (ART). Common service adjustments included decentralization of ART refills, expanded multi-month ART distribution, and digital technology use. Perceived individual-level impacts included social isolation, loss to follow-up, food insecurity, poverty, and increases in adolescent pregnancies and sexually transmitted infections. The need for collaboration among stakeholders were commonly cited as lessons learned by AHISA teams. Survey findings highlight the need for implementation science research to evaluate the effects of pandemic-related HIV service adaptations in SSA.

Children and young women in eastern and southern Africa are key to meeting 2030 HIV targets: time to accelerate action

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.

Delivery of index-linked HIV testing for children: learnings from a qualitative process evaluation of the B-GAP study in Zimbabwe

BACKGROUND

Index-linked HIV testing for children, whereby HIV testing is offered to children of individuals living with HIV, has the potential to identify children living with undiagnosed HIV. The "Bridging the Gap in HIV Testing and Care for Children in Zimbabwe" (B-GAP) study implemented and evaluated the provision of index-linked HIV testing for children aged 2-18 years in Zimbabwe. We conducted a process evaluation to understand the considerations for programmatic delivery and scale-up of this strategy.

METHODS

We used implementation documentation to explore experiences of the field teams and project manager who delivered the index-linked testing program, and to describe barriers and facilitators to index-linked testing from their perspectives. Qualitative data were drawn from weekly logs maintained by the field teams, monthly project meeting minutes, the project coordinator's incident reports and WhatsApp group chats between the study team and the coordinator. Data from each of the sources was analysed thematically and synthesised to inform the scale-up of this intervention.

RESULTS

Five main themes were identified related to the implementation of the intervention: (1) there was reduced clinic attendance of potentially eligible indexes due to community-based differentiated HIV care delivery and collection of HIV treatment by proxy individuals; (2) some indexes reported that they did not live in the same household as their children, reflecting the high levels of community mobility; (3) there were also thought to be some instances of 'soft refusal'; (4) further, delivery of HIV testing was limited by difficulties faced by indexes in attending health facilities with their children for clinic-based testing, stigma around community-based testing, and the lack of familiarity of indexes with caregiver provided oral HIV testing; (5) and finally, test kit stockouts and inadequate staffing also constrained delivery of index-linked HIV testing.

CONCLUSIONS

There was attrition along the index-linked HIV testing cascade of children. While challenges remain at all levels of implementation, programmatic adaptations of index-linked HIV testing approaches to suit patterns of clinic attendance and household structures may strengthen implementation of this strategy. Our findings highlight the need to tailor index-linked HIV testing to subpopulations and contexts to maximise its effectiveness.

Addressing the Know-Do Gap in Adolescent HIV: Framing and Measuring Implementation Determinants, Outcomes, and Strategies in the AHISA Network

Implementation science (IS) uses systematic methods to close gaps between research and practice by identifying and addressing barriers to implementation of evidence-based interventions (EBIs). To reach UNAIDS HIV targets, IS can support programs to reach vulnerable populations and achieve sustainability. We studied the application of IS methods in 36 study protocols that were part of the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA). Protocols focused on youth, caregivers, or healthcare workers in high HIV-burden African countries and evaluated medication, clinical and behavioral/social EBIs. All studies measured clinical outcomes and implementation science outcomes; most focused on early implementation outcomes of acceptability (81%), reach (47%), and feasibility (44%). Only 53% used an implementation science framework/theory. Most studies (72%) evaluated implementation strategies. Some developed and tested strategies, while others adapted an EBI/strategy. Harmonizing IS approaches allows cross study learning and optimization of delivery of EBIs and could support attainment of HIV goals.

Mode of HIV acquisition among adolescents living with HIV in resource-limited settings: A data-driven approach from South Africa

Adolescents living with HIV (ALHIV) face unique treatment and care challenges which may differ by how they acquired HIV, whether vertically (in-utero, perinatal or postnatal exposure during breastfeeding) or sexually (sexual exposure). Distinguishing and documenting the mode of HIV acquisition (MOHA) is crucial to further research on the different needs and outcomes for ALHIV and to tailor HIV services to their needs. Age-based cut-offs have been used to attribute MOHA but have not been validated. We analysed data from a three-wave cohort of n = 1107 ALHIV part of a longitudinal study in South Africa. Age-based MOHA was allocated using age at ART initiation, validated against a logic-tree model based on literature-hypothesised factors: self-reported HIV, sexual, and family history. After testing six ART initiation age cut-offs (10 to 15 years old), we determined the optimal MOHA cut-off age by calculating the sensitivity and specificity for each cut-off, measured against the final logic-tree allocation. Following validation using this longitudinal study, the methodology is extended to 214 additional third-wave participants-adolescent girls and young women living with HIV who became mothers before the age of 20. Finally, descriptive statistics of the final allocations are presented. Among the 1,063 (96.0%) cohort study participants classified, 68.7% acquired HIV vertically, following validation. ART initiation before cut-off age 10 had the highest sensitivity (58.9%) but cut-off age 12 had the largest area under the curve (AUC) (0.712). Among the additional young mothers living with HIV, 95.3% were estimated to have acquired it sexually, following the same algorithm. For this group, while cut-off ages 10 to 12 had the highest sensitivity (92.2%), age 14 had the highest AUC (0.703). ART initiation before 10 years old is strongly associated with vertical HIV acquisition. Therefore, a cut-off age of 10 would remain the recommendation in LMIC regions with similar epidemiology as South Africa for determining MOHA in research and clinic settings.

Economic Well-being and Associated Mediating Pathways to Improved Antiretroviral Therapy Adherence Among Adolescents Living With HIV: A Prospective Cohort Study in South Africa

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.

"I am not shy anymore": A qualitative study of the role of an interactive mHealth intervention on sexual health knowledge, attitudes, and behaviors of South African adolescents with perinatal HIV

BACKGROUND

South Africa has one of the highest burdens of adolescents with perinatally-acquired HIV (APHIV) in the world. APHIV in South Africa have limited access to sexual and reproductive health (SRH) education and services specific to their HIV status. When lacking comprehensive SRH education, APHIV are prone to sexual risk behaviors that can lead to unintended pregnancy, sexually transmitted infections, and HIV transmission. The use of mHealth interventions has been shown to deliver information, foster social support, and improve decision-making skills. In this study, we evaluate how an mHealth intervention influences sexual health knowledge and behaviors in APHIV.

METHODS

We purposively enrolled adolescents from the intervention arm of a randomized clinical trial assessing a multi-module, moderated WhatsApp-based intervention-Interactive Transition Support for Adolescents Living with HIV (InTSHA)-within a government supported clinic in KwaMashu, an urban township of KwaZulu-Natal, South Africa. We conducted in-depth interviews based on World Health Organization guidelines for asking adolescents about SRH. We thematically analyzed data through an iterative, team-based coding approach combining deductive and inductive elements to contextualize SRH attitudes, knowledge, and behaviors before and after receiving the InTSHA intervention.

RESULTS

Of the 21 participants, 13 (61.9%) were female and the mean age was 16.6 years. Most participants reported first learning about SRH as young teenagers in school through non-targeted and negative ways, seeking clarification through peers and the internet rather than clinicians or caregivers. Participants reported that InTSHA provided a holistic perspective on relationships, gender, and sexuality specific to growing up with HIV in South Africa. They praised the ability to give and receive information from peers in a moderated setting through the mHealth intervention, building their confidence, decision-making skills, and communication with partners and caregivers throughout their everyday lives. Despite reporting some technological challenges, adolescents agreed that InTSHA was convenient, confidential, and user-friendly.

CONCLUSIONS

South African APHIV receive incomplete and conflicting sexual education from peers, caregivers, teachers, and technology that can be supplemented by mHealth curricula targeted for the unique needs of APHIV. Future, scaled-up mHealth interventions can lower SRH stigma by expanding access to sexual education and peer support, supplementing adolescents' existing SRH education.

Systematic Review of mHealth Interventions for Adolescent and Young Adult HIV Prevention and the Adolescent HIV Continuum of Care in Low to Middle Income Countries

Adolescents and young adults (AYA) in low to middle income countries (LMIC) have poorer outcomes along each step in the HIV continuum of prevention and care compared to younger children or older adults. The use of mHealth technology provides a potentially promising implementation strategy for interventions to remedy these disparities. We therefore conducted a systematic review of the English literature and conference proceedings from January 1, 2000 to April 1, 2021 evaluating mHealth interventions targeting AYA along each step of the HIV continuum of care in LMIC. We identified 27 mHealth interventions across the HIV continuum, with no interventions addressing transition from pediatric to adult care. The majority of studies were single arm, uncontrolled or underpowered, with few randomized trials resulting in mixed and inconclusive outcomes. mHealth interventions have potential to remedy disparities along the HIV continuum of care for AYA in LMIC but larger, powered randomized trials are needed.

Viral suppression among adolescents on HIV treatment in the Sedibeng District, Gauteng province

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%.

'They can stigmatize you': a qualitative assessment of the influence of school factors on engagement in care and medication adherence among adolescents with HIV in Western Kenya

School-related factors may influence retention in care and adherence to antiretroviral therapy (ART) among adolescents with human immunodeficiency virus (HIV). We analyzed data from in-depth interviews with 40 adolescents with HIV (aged 14 -19 years), 40 caregivers of adolescents with HIV, and 4 focus group discussions with healthcare workers to evaluate contextual factors affecting adherence to ART and clinic attendance among adolescents, with a focus on the school environment. Informed by Anderson's Model of Health Services Utilization, transcripts were systematically coded and synthesized to identify school-related themes. All groups identified the school environment as a critical barrier to engagement in HIV care and medication adherence for adolescents with HIV. Adolescent participants reported inflexible school schedules and disclosure to school staff as the biggest challenges adhering to clinic appointments and ART. Adolescents described experiencing stigma and discrimination by peers and school staff and would adjust when, where and how often they took ART to avoid inadvertent disclosure. Boarding school students faced challenges because they had limited private space or time. Caregivers were often instrumental in navigating school permissions, including identifying a treatment supporter among school staff. Additional research engaging school staff may guide interventions for schools to reduce stigma and improve adherence and retention.

Temporal changes in paediatric and adolescent HIV outcomes across the care continuum in Zambia: an interrupted time-series analysis

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.

“We Should Be Taught Self-Respect, Self-Confidence and Self-Love”: Youth Perspectives of Adult Influences on Their Sexuality and Relationships Among South African Adolescents Living With HIV

Introduction

Of the 1.75 million adolescents aged 10–19 years living with HIV globally, 84% reside in sub-Saharan Africa. This problem is most acute in South Africa, where there are 720,000 adolescents living with HIV (ALHIV). ALHIV navigate the same challenges as other adolescents—such as puberty and first relationships—as well as challenges specific to their HIV-status—including stigma, disclosure, and concerns about HIV transmission. This dual burden calls for tailored sexual and reproductive health (SRH) programs. Here, we qualitatively explore the reflections of South African ALHIV on SRH education, communication, and discussion provided by adults in schools, clinics, and the home related to their unique SRH needs.

Methods

This paper reports on qualitative data from a mixed-methods study to inform interventions that meet the SRH needs of ALHIV. In-depth interviews (N = 20) were conducted with ALHIV recruited from two clinics in Cape Town, South Africa. Nine males and 11 females aged 16–19 participated in semi-structured in-depth interviews to discuss their sexual health as ALHIV. The interview guide explored 1) perceived SRH needs; 2) healthy living with HIV; 3) future goals; 4) intimate relationships; 5) psychosocial challenges; and 6) preferred interventions. Data were thematically applied to an iteratively-developed codebook and analyzed by the cross-cultural research team using NVivo 12.

Results

These qualitative data reveal the pressing needs among ALHIV for open communication and accurate information about sexuality and HIV, given the risk to themselves and their partners as they enter intimate relationships. Three themes emerged from the data: 1) Intergenerational pressures coming from caregivers, clinicians, and teachers often stigmatize the sexual heath behaviors of ALHIV; 2) When present, open intergenerational communication can provide ALHIV with crucial information, resources, and social support that supports healthy decisions, and 3) ALHIV offer specific ideas about how adults can support their decision-making in the transition to adulthood.

Conclusions

Findings highlight adolescents' recommendations for programs involving open communication, stigma-reduction around sexuality, and support from both peer and adult mentors. This study lays the foundation for strategies to improve intergenerational communication about sexual health to promote positive approaches to sexuality for ALHIV.

Factors associated with viral suppression among adolescents on antiretroviral therapy in Free State province, South Africa

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.

HIV virological non-suppression is highly prevalent among 18- to 24-year-old youths on antiretroviral therapy at the Kenyan coast

BACKGROUND

In sub-Saharan Africa, data on virologic outcomes of young people living with HIV (YLWH) enrolled on antiretroviral therapy (ART) remains scarce. In this study, we describe the prevalence of HIV virological non-suppression (VNS) and its associated factors among YLWH aged 18-24 years from the Kenyan coast.

METHODS

Data were analyzed for 384 YLWH who participated in a larger cross-sectional study conducted between November 2018 and September 2019 in two counties at the Kenyan coast (Kilifi and Mombasa). Descriptive statistics were used to summarize sample characteristics and logistic regression was used for statistical modeling of factors associated with VNS. In this study, VNS was defined as plasma viral load ≥ 1000 copies/mL.

RESULTS

Among these YLWH with a mean age of 20.7 years (SD = 2.2); 55.5% females, the overall prevalence of VNS was 32.0% (95% Confidence interval (95% CI): 27.5, 36.9%). In the multivariable logistic regression analysis, being from a largely rural setting (adjusted Odds Ratio (aOR) 1.73, 95% CI 1.10, 2.71; p = 0.02), underweight (aOR 1.87, 95% CI 1.16, 3.01; p = 0.01) and low self-reported ART adherence (aOR 2.83, 95% CI 1.34, 6.00; p = 0.01) were significantly associated with higher odds of VNS in YLWH.

CONCLUSIONS

In this study, high levels of VNS were observed among YLWH and this was significantly associated with rural residency, nutritional and ART adherence problems. ART adherence counselling and nutritional support and education should be intensified in this setting targeting YLWH residing mostly in rural areas. Given the high frequency of VNS, there is need to closely monitor viral load and profile HIV drug resistance patterns in youths from the Kenyan coast with confirmed virologic failure. The latter will help understand whether drug resistance also contributes to poor viral suppression in addition to, or exclusive of suboptimal ART adherence.

The Role of Families in Adolescent and Young Adults' PrEP Use

While pre-exposure prophylaxis (PrEP) is a key HIV prevention tool for adolescents and young adults (AYAs), its initiation and sustained use is shaped by AYAs' unique social contexts, including family. We explored the role of families in AYAs' PrEP use through qualitative in-depth interview (IDI) data from iPrevent, an end-user study designed to identify factors that could optimize PrEP adherence among South African youth (18-24 years old). These data were collected using a semi structured guide and were analysed using an inductive approach. Several themes describing family influence on AYAs' PrEP use emerged including family support; family attitude towards PrEP; and the family's ability to obviate PrEP disclosure challenges. In addition, dimensions of family closeness, categorized as 'close', 'in-between' and 'loose-knit,' appeared important in contextualizing family influence on AYAs' PrEP use. We found that family remains a proximal and fundamental social system in which AYA are socialized and greater family engagement could aid PrEP implementation in this priority population.

Understanding Repeat Positive HIV Testing in South Africa Under Changing Treatment Guidelines

Some people with HIV (PWH) test positive multiple times without initiating antiretroviral therapy (ART). We surveyed 496 ART-eligible PWH following routine HIV testing at three clinics in Soweto and Gugulethu, South Africa in 2014-2015. Among repeat positive testers (RPTs) in this cohort, we compared rates of treatment initiation by prior treatment eligibility and assessed psychosocial predictors of treatment initiation in logistic regression models. RPTs represented 33.8% of PWH in this cohort. Less than half of those who reported eligibility for ART on prior testing started treatment upon retesting, in contrast to two thirds of RPTs who were previously ineligible for treatment who started treatment once they learned of their eligibility. Those who reported coping through substance use were more likely to decline treatment versus those not using substances. PWH who test repeatedly represent a vulnerable population at risk for ART non-initiation who may benefit from interventions addressing individualized coping strategies.

Predictors and consequences of HIV status disclosure to adolescents living with HIV in Eastern Cape, South Africa: a prospective cohort study

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.

Interventions addressing the adolescent HIV continuum of care in South Africa: a systematic review and modified Delphi analysis

INTRODUCTION

Compared with adults, adolescents in South Africa have larger gaps at each step of the HIV continuum of care resulting in low levels of viral suppression.

METHODS

We conducted a systematic review and modified Delphi analysis of interventions addressing the HIV continuum of care for adolescents in South Africa. We searched PubMed, Science Direct, and Google Scholar and online conference proceedings from the International AIDS Society, the International AIDS Conference, and the Conference on Retrovirology and Opportunistic Infections from 1 January 2010 to 30 September 2020. We then conducted a modified Delphi analysis with 29 researchers involved in the National Institutes of Health's Fogarty International-supported Adolescent HIV Implementation Science Alliance-South Africa to evaluate interventions for efficacy, feasibility and potential for scale-up.

RESULTS

We identified nine initial published articles containing interventions addressing the adolescent HIV continuum of care in South Africa, including five interventions focused on HIV diagnosis, two on antiretroviral therapy adherence and two on retention in care. No studies addressed linkage to care or transition from paediatric to adult care. Two studies discussed intervention costs. In-home and HIV self-testing, community-based adherence support, and provision of adolescent-friendly services were the most impactful and scalable interventions addressing the adolescent HIV continuum of care.

CONCLUSION

Future interventions should work comprehensively across the adolescent HIV continuum of care and be tailored to the specific needs of adolescents.

Development of a transition readiness score for adolescents living with perinatally-acquired HIV and transitioning to adult care

We created a transition readiness score for adolescents with perinatally-acquired HIV as they transition from pediatric to adult care. Of the 199 adolescents who transitioned to adult care, 84 (42%) had viral suppression (< 200 copies/ml) one year after transition. Adolescents on first-line ART, with documented HIV status disclosure, and higher rating on the HIV Adolescent Readiness to Transition Scale had significantly higher odds of viral suppression after transition. Conversely, females, those with older age at ART initiation, and those with prior alcohol use had significantly lower odds of viral suppression after transition. Using these data, we created a transition readiness score organized into low, intermediate, and high levels of transition readiness. This transition readiness score can be used to identify adolescents who are likely ready to transition to adult care and identify additional areas for intervention to improve the likelihood of successful transition for those with lower transition readiness scores.

Two years after lockdown: reviewing the effects of COVID-19 on health services and support for adolescents living with HIV in South Africa

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.

Group antenatal care for improving retention of adolescent and young pregnant women living with HIV in Kenya

BACKGROUND

Pregnant and breastfeeding adolescents and young women living with HIV (AYWLH) have lower retention in prevention of mother-to-child transmission (PMTCT) services compared to older women.

METHODS

We evaluated a differentiated service model for pregnant and postnatal AYWLH at seven health facilities in western Kenya aimed at improving retention in antiretroviral treatment (ART) services. All pregnant AYWLH < 25 years presenting for antenatal care (ANC) were invited to participate in group ANC visits including self-care and peer-led support sessions conducted by health facility nurses per national guidelines. ART register data were used to assess loss to follow-up (LTFU) among newly-enrolled pregnant adolescent (< 20 years) and young women (20-24 years) living with HIV starting ART in the pre-period (January-December 2016) and post-period (during implementation; December 2017-January 2019). Poisson regression models compared LTFU incidence rate ratios (IRR) in the first six months after PMTCT enrollment and risk ratios compared uptake of six week testing for HIV-exposed infants (HEI) between the pre- and post-periods.

RESULTS

In the pre-period, 223 (63.2%) of 353 pregnant AYWLH newly enrolled in ANC had ART data, while 320 (71.1%) of 450 in the post-period had ART data (p = 0.02). A higher proportion of women in the post-period (62.8%) had known HIV-positive status at first ANC visit compared to 49.3% in the pre-period (p < 0.001). Among pregnant AYWLH < 20 years, the incidence rate of LTFU in the first six months after enrollment in ANC services declined from 2.36 per 100 person months (95%CI 1.06-5.25) in the pre-period to 1.41 per 100 person months (95%CI 0.53-3.77) in the post-period. In both univariable and multivariable analysis, AYWLH < 20 years in the post-period were almost 40% less likely to be LTFU compared to the pre-period, although this finding did not meet the threshold for statistical significance (adjusted incidence rate ratio 0.62, 95%CI 0.38-1.01, p = 0.057). Testing for HEI was 10% higher overall in the post-period (adjusted risk ratio 1.10, 95%CI 1.01-1.21, p = 0.04).

CONCLUSIONS

Interventions are urgently needed to improve outcomes among pregnant and postnatal AYWLH. We observed a trend towards increased retention among pregnant adolescents during our intervention and a statistically significant increase in uptake of six week HEI testing.

"It must start with me, so it started with me": A qualitative study of Project YES! youth peer mentor implementing experiences supporting adolescents and young adults living with HIV in Ndola, Zambia

BACKGROUND

Little is known about youth-led approaches to addressing HIV-related outcomes among adolescents and young adults (AYA) living with HIV. In response, Project YES! hired and trained youth living with HIV as peer mentors (YPMs) in four HIV clinics in Ndola, Zambia to hold meetings with 276 15-24-year-olds living with HIV. Within this randomized controlled trial, a qualitative sub-study was conducted to explore YPMs' implementing experiences.

METHODS

In-depth interviews were conducted with the eight YPMs (50% female) ages 21-26 years. YPMs were asked about their experiences working with clients, their feedback on program components, and what the experience meant to them personally and professionally. Interviews were audio-recorded, transcribed verbatim, and thematic analysis was performed.

RESULTS

YPMs connected with AYA clients by discussing shared struggles, modeling positive health behaviors, and establishing judgement-free environments. YPMs experienced powerful personal transformations in HIV-related health behaviors, conceptions of self, and plans for the future. Many expressed now seeing themselves as community leaders-"ambassadors", "game changers"-and "not just alone in this world." They described newfound commitments to reaching personal and professional goals. YPMs were adamant that Project YES! should expand so other HIV-positive AYA might benefit.

CONCLUSION

Well-trained and compensated YPMs who are integrated into HIV clinics can support AYA in unique and important ways due to their shared experiences. The transformational experience of becoming YPMs empowers youth to see themselves as role models and leaders. Future programs should engage youth living with HIV as partners in efforts to end the HIV epidemic.

"Who am I going to stay with? Who will accept me?": family-level domains influencing HIV care engagement among disengaged adolescents in Kenya

INTRODUCTION

Adolescents living with HIV (ALHIV, ages 10-19) have developmentally specific needs in care, and have lower retention compared to other age groups. Family-level contexts may be critical to adolescent HIV outcomes, but have often been overlooked. We investigated family-level factors underlying disengagement and supporting re-engagement among adolescents disengaged from HIV care.

METHODS

Semi-structured interviews were performed with 42 disengaged ALHIV, 32 of their caregivers and 28 healthcare workers (HCW) in the Academic Model Providing Access to Healthcare (AMPATH) program in western Kenya, from 2018 to 2020. Disengaged ALHIV had ≥1 visit within the 18 months prior to data collection at one of two sites and nonattendance ≥60 days following their last scheduled appointment. HCW were recruited from 10 clinics. Transcripts were analysed through thematic analysis. A conceptual model for family-level domains influencing adolescent HIV care engagement was developed from these themes.

RESULTS

Family-level factors emerged as central to disengagement. ALHIV-particularly those orphaned by the loss of one or both parents-experienced challenges when new caregivers or unstable living situations limited support for HIV care. These challenges were compounded by anticipated stigma; resultant non-disclosure of HIV status to household members; enacted stigma in the household, with overwhelming effects on adolescents; or experiences of multiple forms of trauma, which undermined HIV care engagement. Some caregivers lacked finances or social support to facilitate care. Others did not feel equipped to support adolescent engagement or adherence. Regarding facilitators to re-engagement, participants described roles for household disclosure; and solidarity from caregivers, especially those also living with HIV. Family-level domains influencing HIV care engagement were conceptualized as follows: (1) adolescent living situation and contexts; (2) household material resources or poverty; (3) caregiver capacities and skills to support adolescent HIV care; and (4) HIV stigma or solidarity at the household level.

CONCLUSIONS

Family-level factors are integral to retention in care for ALHIV. The conceptual model developed in this study for family-level influences on care engagement may inform holistic approaches to promote healthy outcomes for ALHIV. Developmentally appropriate interventions targeting household relationships, disclosure, HIV stigma reduction, HIV care skills and resources, and economic empowerment may promote adolescent engagement in HIV care.

Stewart GC, Wamalwa DC, Kohler PK. “I Have Actually not Lost any Adolescent Since I Started Engaging Them one on one:” Training Satisfaction and Subsequent Practice among Health Providers Participating in a Standardized Patient Actor Training to Improve Adolescent Engagement in HIV Care

Background: Poor health care worker (HCW) interactions with adolescents negatively influence engagement in HIV care. We assessed the impact of standardized patient actor training on HCW competence in providing adolescent HIV care in Kenya. Methods: We conducted pre-post cross-sectional surveys and qualitative exit interviews during a stepped wedge randomized trial. Cross-sectional surveys assessed self-rated competence in providing adolescent services before and after the intervention, and training satisfaction. In-depth interviews with a subset of HCW participants one year after training. Results: Over 90% of HCWs reported satisfaction with the training and there was significant improvement in self-rated competence scores (mean = 4.63 [highest possible score of 5] post-training vs 3.86 pre-training, p < 0.001). One-year following training, HCWs reported using skills in patient-centered communication and structuring an adolescent clinical encounter. Conclusions: This SP training intervention improved self-rated competence and showed sustained perceived impact on HCW skills in adolescent HIV service provision one year later.

Mobile Phone-Based Intervention Among Adolescents Living With Perinatally Acquired HIV Transitioning from Pediatric to Adult Care: Protocol for the Interactive Transition Support for Adolescents Living With HIV using Social Media (InTSHA) Study

BACKGROUND

Adolescents living with perinatally acquired HIV often have poor retention in care and viral suppression during the transition from pediatric to adult-based care.

OBJECTIVE

The aim of this study is to evaluate a mobile phone-based intervention, Interactive Transition Support for Adolescents Living With HIV using Social Media (InTSHA), among adolescents living with perinatally acquired HIV as they transition from pediatric to adult care in South Africa.

METHODS

InTSHA uses encrypted, closed group chats delivered via WhatsApp (Meta Platforms Inc) to develop peer support and improve communication between adolescents, their caregivers, and health care providers. The intervention is based on formative work with adolescents, caregivers, and health care providers and builds on several existing adolescent support programs as well as the Social-ecological Model of Adolescent and Young Adult Readiness for Transition (SMART). The final InTSHA intervention involves 10 modules conducted weekly through moderated WhatsApp group chats with adolescents and separately with their caregivers. We will randomly assign 80 South African adolescents living with perinatally acquired HIV who are aware of their HIV status and aged between 15 and 19 years to receive either the intervention (n=40) or standard of care (n=40).

RESULTS

We will measure acceptability of the intervention as the primary outcome and evaluate feasibility and preliminary effectiveness for retention in care and viral suppression after completion of the intervention and at least 6 months after randomization. In addition, we will measure secondary outcomes evaluating the impact of the InTSHA intervention on peer support, self-esteem, depression, stigma, sexual education, connection to health care providers, and transition readiness. Enrollment began on April 15, 2021. As of December 31, 2021 a total of 78 out of expected 80 participants have been enrolled.

CONCLUSIONS

If successful, the intervention will be evaluated in a fully powered randomized controlled trial with a larger number of adolescents from urban and rural populations to further evaluate the generalizability of InTSHA.

Attrition from HIV care among youth initiating ART in youth-only clinics compared with general primary healthcare clinics in Khayelitsha, South Africa: a matched propensity score analysis

INTRODUCTION

Youth living with HIV (YLWH) are less likely to initiate antiretroviral therapy (ART) and remain in care than older adults. It is important to identify effective strategies to address the needs of this growing population and prevent attrition from HIV care. Since 2008, two clinics have offered youth-targeted services exclusively to youth aged 12-25 in Khayelitsha, a high HIV-prevalence, low-income area in South Africa. We compared ART attrition among youth in these two clinics to youth in regular clinics in the same area.

METHODS

We conducted a propensity score matched cohort study of individuals aged 12-25 years initiating ART at eight primary care clinics in Khayelitsha between 1 January 2008 and 1 April 2018. We compared attrition, defined as death or loss to follow-up, between those attending two youth clinics and those attending general primary healthcare clinics, using Cox proportional hazards regression. Follow-up time began at ART initiation and ended at attrition, clinic transfer or dataset closure. We conducted sub-analyses of patients attending adherence clubs.

RESULTS

The distribution of age, sex and CD4 count at ART initiation was similar across Youth Clinic A (N = 1383), Youth Clinic B (N = 1299) and general clinics (N = 3056). Youth at youth clinics were more likely than those at general clinics to have initiated ART before August 2011 (Youth Clinic A: 16%, Youth Clinic B: 23% and general clinics: 11%). Youth clinics were protective against attrition: HR 0.81 (95% CI: 0.71-0.92) for Youth Clinic A and 0.85 (0.74-0.98) for Youth Clinic B, compared to general clinics. Youth Clinic A club patients had lower attrition after joining an adherence club than general clinic patients in adherence clubs (crude HR: 0.56, 95% CI: 0.32-0.96; adjusted HR: 0.48, 95% CI: 0.28-0.85), while Youth Clinic B showed no effect (crude HR: 0.83, 95% CI: 0.48-1.45; adjusted HR: 1.07, 95% CI: 0.60-1.90).

CONCLUSIONS

YLWH were more likely to be retained in ART care in two different youth-targeted clinics compared to general clinics in the same area. Our findings suggest that multiple approaches to making clinics more youth-friendly can contribute to improving retention in this important group.

Intimate partner violence and the HIV care and treatment cascade among adolescent girls and young women in DREAMS, South Africa

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.

Cancer in HIV-positive and HIV-negative adolescents and young adults in South Africa: a cross-sectional study

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.

Cancer risk in adolescents and young adults living with HIV in South Africa: a nationwide cohort study

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.

Second-generation mother-to-child HIV transmission in South Africa is characterized by poor outcomes

OBJECTIVE

The worldwide incidence of pregnancy for women living with perinatal HIV infection is increasing. Subsequently, there is growing risk of second-generation mother-to-child HIV transmission. The infant clinical outcomes for such a phenomenon have yet to be described.

DESIGN

As part of a wider observational study in KwaZulu-Natal, South Africa, six infants with in-utero HIV infection were identified as being born to mothers with perinatal HIV infection.

METHODS

Blood results and clinical data were collected in the first 3 years of life. In two cases, sample availability allowed confirmation by phylogenetic analysis of grandmother-to-mother-to-child HIV transmission.

RESULTS

Outcomes were poor in all six cases. All six mothers had difficulty administering twice daily combination antiretroviral therapy to their infants due to difficulties with acceptance, disclosure, poor health and being themselves long-term nonprogressors. Nonnucleoside reverse transcriptase inhibitor-resistant virus was detected in all mothers tested. None of the infants maintained suppression of viraemia on combination antiretroviral therapy. One infant died, and another was lost to follow-up.

CONCLUSION

As the numbers of second-generation mother-to-child transmissions increase, it is important to highlight that this mother-infant dyad represents an extremely vulnerable group. In order for them to survive and thrive, these infants' mothers require their specific needs to be addressed and given intensive support.

"Those People Motivate and Inspire Me to Take My Treatment." Peer Support for Adolescents Living With HIV in Cape Town, South Africa

Adherence to antiretroviral therapy (ART) and psychosocial support to manage stigma and disclosure is essential for adolescents living with HIV (ALHIV). Peer support groups can help ALHIV and their families live successfully with HIV. This qualitative study aimed to examine adolescent and caregiver perspectives on peer support groups. Three themes emerged: (1) peer support encouraged adherence to ART, (2) serostatus disclosure outside the family was perceived as difficult, and (3) the peer support group fostered fundamental and meaningful peer relationships for ALHIV. Caregivers felt peer support groups increased self-acceptance and adherence for ALHIV across 3 domains: (1) as motivation for families and adolescents, (2) to increase adolescent independence and maturity, and (3) to help adolescents accept their HIV status and live successfully with HIV. These data highlight the importance of psychosocial support groups for ALHIV and caregivers, illustrating the benefits of a safe space with trusted relationships and open communication.

Development and validation of the HIV adolescent readiness for transition scale (HARTS) in South Africa

INTRODUCTION

Adolescents living with perinatally acquired HIV have low rates of retention in care and viral suppression after the transition from paediatric to adult care. In this study, we developed and validated a tool to identify adolescent transition readiness.

METHODS

We developed the HIV Adolescent Readiness for Transition Scale (HARTS) from June 2016 to May 2019 by iteratively adapting existing transition readiness scales for other chronic illnesses by conducting focus groups with 11 healthcare providers and 20 adolescents in South Africa. We administered a preliminary questionnaire to 131 adolescents to determine psychometric properties and assess test-retest variability. We used confirmatory factor analysis to verify the proposed scale structure using the underlying variable approach. We correlated responses to self-described transition readiness and age using linear regression. We subsequently validated the scale by prospectively administering it to 199 adolescents in a second South African setting before their transition. We then used multivariable logistic regression to assess the effects of the HARTS and relevant socio-behavioural covariates on viral suppression one year after transition.

RESULTS

We identified four domains relevant to transition readiness: disclosure, health navigation, self-advocacy and health literacy. Fifteen questions with a significant factor loading of 0.3 to 0.9 were identified. No significant test-retest variability was seen among 10% of participants. Positive correlations with self-described transition readiness were significant with the overall HARTS and domains of health navigation, self-advocacy and health literacy. In the prospective analysis, for adolescents not using drugs, each 10-point increase in the HARTS was associated with 0.62 odds of viral failure (95% CI 0.45 to 0.86; p = 0.004). The individual domains of self-advocacy (AOR 0.56; 95% CI 0.33 to 0.94; p = 0.029), disclosure (AOR 0.02; 95% CI 0.01 to 0.25; p = 0.002), health navigation (AOR 0.51; 95%CI 0.25 to 1.02; p = 0.056) and health literacy (AOR 0.37; 95% CI 0.10 to 1.30; p = 0.121) were associated with viral failure adjusting for age at antiretroviral therapy initiation, ART regimen, sex, disclosure status, and alcohol use in both analyses.

CONCLUSIONS

The HARTS is a validated scale that can be used to identify which adolescents may require additional interventions prior to transitioning to adult care to improve viral suppression after transition.
