Predictors of successful transition of adolescents and young adults living with HIV from pediatric to adult-oriented care in southern Ethiopia: a retrospective cohort study

BACKGROUND

The introduction of highly active antiretroviral therapy has significantly improved the life expectancies of children and adolescents living with HIV, leading to an increased number transitioning to adult care. However, there has been a lack of studies in Ethiopia focusing on factors influencing the success of this transition. Therefore, this study aimed to determine predictors of a successful transition from pediatric to adult HIV clinics among adolescents and young adults living with HIV in health facilities in southern Ethiopia.

METHODS

A retrospective cohort study included 337 adolescents and young adults who transitioned to adult-oriented HIV care. Successful transition was defined as having a viral load of less than 1000 copies/ml and maintaining care during the first year post-transition. Patients' antiretroviral therapy (ART) cards and monitoring charts were reviewed. Secondary data analysis was conducted using a multivariable binary logistic regression model to identify predictors of a successful transition. Using the variance inflation factor, we checked for multi-collinearity between variables and assessed model fitness with the Hosmer and Lemeshow goodness-of-fit test. Adjusted Odds Ratio (AOR) with 95% confidence intervals (CI) and P-value ≤ 0.05 measured the strength of association and statistical significance.

RESULTS

Of 337 participants, 230 (68.25%) successfully transitioned (95% CI = 63.25, 73.25). Transitioning at age 18 or older (AOR = 4.25; 95% CI = 2.29, 7.87), residing in an urban area (AOR = 1.78; 95% CI = 1.04, 3.02), and being on antiretroviral therapy for more than two years (AOR = 4.25; 95% CI = 1.17, 4.94; P < 0.017) were identified as positive predictors and opportunistic infection (AOR = 0.34; 95% CI = 0.15, 0.75; P < 0.008) was identified as a negative predictor for a successful transition from pediatric to adult ART clinic.

CONCLUSION

This study sheds light on the challenges faced by HIV patients transitioning from pediatric to adult care, with less than 70% successfully navigating this critical phase. Factors such as age at transition, residence, duration of ART, and the presence of opportunistic infections were identified as key predictors of successful transition. The findings underscore the urgent need for tailored interventions, including standardized transition plans that address age and urban/rural disparities, to enhance transition outcomes for adolescents and young adults living with HIV in the region.

"I want to be healthy and move on": A qualitative study of barriers and facilitators to antiretroviral treatment adherence among young adult survivors with perinatal HIV in Thailand

We know that HIV treatment outcome depends on antiretroviral treatment (ART) adherence. Young adults with perinatal HIV (YPHIV) who survived have endured various adherence challenges in their adolescent years. While some of them could maintain perfect adherence with sustainable virologic suppression, many experienced one or more episodes of virologic failure. We explored factors affecting ART adherence from real-life experiences of YPHIV. A qualitative study was conducted between June and November 2022. Twenty YPHIV aged 21-29 years with a history of virologic failure and resumed virologic suppression during adolescent years were invited to share their experiences through individual in-depth interviews. Audio records were transcribed verbatim and analyzed using deductive thematic analysis. We divided excerpts into two themes: barriers and facilitators to ART adherence. The socio-ecological model was used to frame subthemes at personal, societal, and healthcare system levels. Most barriers to adherence were concentrated at the personal level, including work/study-related conditions, personal entertainment, medication issues, mental health problems, thought, and belief. At the societal level, social activities and fear of HIV disclosure were frequently mentioned as barriers. Medical care cost was the only identified barrier at the healthcare system level. The facilitators to adherence at the personal level included perceiving health deterioration, being afraid of hospitalization and medical procedures, and wishing to be healthy and move on. At the same time, perceived family support and determination to complete family without HIV transmission were identified as facilitators at the societal level. Service behaviors of healthcare providers were mentioned as facilitators to adherence at the healthcare system level. From this study, most factors associated with non-adherence in adolescents were at the personal level, and the fear of HIV disclosure was critical at the societal level. The key facilitator to adherence was the determination to be healthy and have a promising future. Our findings reinforce the importance of establishing youth-friendly services in the existing HIV care setting. More time allocation for tailored individual counseling, using other novel approaches like mHealth, online media, and involvement of social support from different sectors might be beneficial to maximize adherence self-efficacy during the transitional period of YPHIV.

A qualitative assessment of retention in HIV care among adolescents and young adults (AYA) living with HIV in New York City

Retention in HIV care is a critical precursor to ending the epidemic yet remains suboptimal in the United States. Gaining an understanding of the challenges faced by adolescents and young adults (AYA) living with HIV is essential to improving retention in HIV care. This study explored the barriers and facilitators to retention in care among Black and Hispanic AYA living with HIV. Audio-recorded semi-structured interviews were conducted with 20 AYA living with HIV ages 16-29 years in New York City. Our methods entailed an inductive content analysis to explore key concepts, reconcile codes, and identify a theme, categories, and subcategories. Bronfenbrenner's socioecological model evolved as an organizing framework around barriers and facilitators to retention in care at the individual, interpersonal, healthcare system, and structural level. Data analysis yielded one overarching theme-the influence of psychosocial factors on retention in HIV care. Psychological struggles, powerlessness, clinic-level characteristics, and socioeconomic struggles were barriers reported by participants. Self-responsibility, social support, patient-friendly healthcare services, and socioeconomic resources emerged as facilitators. Retention in HIV care among AYA living with HIV is a multifaceted and complex phenomenon that involves multiple systems. Strengthening patients, healthcare system, and community partnerships can help address some of the HIV-related health disparities.

High mortality in adolescents and young adults with perinatally-acquired HIV in Thailand during the transition to adulthood

Transitioning from pediatric to adult care remains a challenge for adolescents and young adults with perinatally-acquired HIV (AYA-PHIV). We assessed treatment outcomes and mortality among Thai AYA-PHIV. The study included AYA-PHIV who reached age 18-24 years who started antiretroviral treatment during childhood at five pediatric HIV clinics across Thailand. From November 2020-July 2021, data were gathered from a cohort database, medical records, and the Thai National AIDS Program. Of 811 eligible AYA-PHIV, 93% were alive; median age 22.3 years (IQR 20.6-23.7), treatment duration 16.1 years (IQR 13.4-18.0). Current HIV care was provided in adults (71%) and pediatric clinics (29%). Treatment regimens included non-nucleoside reverse transcriptase inhibitors (55%), protease inhibitors (36%), and integrase inhibitors (8%); 78% had HIV RNA <200 copies/ml. Of the 7.0% who died, median age at death was 20.8 years (IQR 20.6-22.1); 88% were AIDS-related death. Mortality after age 18 was 1.76 per 100-person years (95% confidence interval 1.36-2.28). Those with CD4 <200 cell/mm3 at age 15 had higher risk of mortality (adjusted hazard ratio 6.16, 95% CI 2.37-16.02). In conclusion, the high mortality among Thai AYA-PHIV indicated the need for better systems to support AYA-PHIV during the transition to adulthood.

Estimating the costs of adolescent HIV care visits and an intervention to facilitate transition to adult care in Kenya

INTRODUCTION

Adolescents with HIV in sub-Saharan Africa face challenges transitioning to adult HIV care, which can affect long-term HIV care adherence and retention. An adolescent transition package (ATP) focused on transition tools can improve post-transition clinical outcomes, but its implementation costs are unknown.

METHODS

We estimated the average cost per patient of an HIV care visit and ATP provision to adolescents. Data was collected from 13 HIV clinics involved in a randomized clinical trial evaluating ATP in western Kenya. We conducted a micro-costing and activity-driven time estimation to assess costs from the provider perspective. We developed a flow-map, conducted staff interviews, and completed time and motion observation. ATP costs were estimated as the difference in average cost for an HIV care transition visit in the intervention compared to control facilities. We assessed uncertainty in costing estimates via Monte Carlo simulations.

RESULTS

The average cost of an adolescent HIV care visit was 29.8USD (95%CI 27.5, 33.4) in the standard of care arm and 32.9USD (95%CI 30.5, 36.8) in the ATP intervention arm, yielding an incremental cost of 3.1USD (95%CI 3.0, 3.4) for the ATP intervention. The majority of the intervention cost (2.8USD) was due ATP booklet discussion with the adolescent.

CONCLUSION

The ATP can be feasibly implemented in HIV care clinics at a modest increase in overall clinic visit cost. Our cost estimates can be used to inform economic evaluations or budgetary planning of adolescent HIV care interventions in Kenya.

Experiences of adolescents living with HIV on transitioning from pediatric to adult HIV care in low and middle-income countries: A Qualitative Evidence Synthesis Protocol

In South Africa, it is estimated that approximately 320,000 adolescents living with HIV (ALHIV) will transition from pediatric to adult antiretroviral treatment (ART) by 2028. However, the age period of 10-19 years is accompanied by a myriad of barriers that challenge the transition process, and continued adherence to ART. The transition process involves ALHIV taking charge of their own health and disease management which raises challenges for their retention in care. Managing transition becomes particularly challenging in low-resource contexts as their healthcare systems are not adapted to the specific needs it requires. There is a need to garner an understanding of existing transition practices which address the specific needs of adolescents and is optimized to their requirements and available resources within a low- or middle-income country context. This review will include all qualitative and mixed method studies which will facilitate a deeper understanding the experiences of ALHIV on transition experiences. The review will specifically look at studies conducted in low- and middle-income countries. The included studies must be presented in the English language and published between 2010-2023. The search strategy will be finalized with consultation with an information specialist. All three reviewers will be present throughout all stages of the review. One reviewer will work independently on the initial screening of studies and another reviewer will assist in checks. After data is extracted, the data will be thematically analyzed with the use of Atlas.Ti computer software. No ethics approval is required and the review will be published in peer reviewed journals and submitted to conferences. PROSPERO registration number: CRD42023396459.

An adapted algorithm for patient engagement in care for young people living with perinatal HIV in England

BACKGROUND

Evidence suggests that engagement in care (EIC) may be worse in young people living with perinatal HIV (YPLPHIV) compared to adults or children living with HIV. We took a published EIC algorithm for adults with HIV, which takes patients' clinical scenarios into account, and adapted it for use in YPLPHIV in England, to measure their EIC.

METHODS

The adult algorithm predicts when in the next 6 months the next clinic visit should be scheduled, based on routinely collected clinical indicators at the current visit. We updated the algorithm based on the latest adult guidelines at the time, and modified it for young people in paediatric care using the latest European paediatric guidelines. Paediatric/adolescent HIV consultants from the UK reviewed and adapted the resulting flowcharts. The adapted algorithm was applied to the Adolescent and Adults Living with Perinatal HIV (AALPHI) cohort in England. Data for 12 months following entry into AALPHI were used to predicted visits which were then compared to appointment attendances, to measure whether young people were in care in each month. Proxy markers (e.g. dates of CD4 counts, viral loads (VL)) were used to indicate appointment attendance.

RESULTS

Three hundred sixteen patients were in AALPHI, of whom 41% were male, 82% of black African ethnicity and 58% born abroad. At baseline (time of AALPHI interview) median [IQR] age was 17 [15-18] years, median CD4 was 597 [427, 791] cells/µL and 69% had VL ≤50c/mL. 10 patients were dropped due to missing data. 306 YPLPHIV contributed 3,585 person months of follow up across the 12 month study in which a clinic visit was recorded for 1,204 months (38/1204 dropped due to missing data). The remaining 1,166 months were classified into 3 groups: Group-A: on ART, VL ≤ 50c/mL-63%(734/1,166) visit months, Group-B: on ART, VL > 50c/mL-27%(320/1,166) Group-C: not on ART-10%(112/1,166). Most patients were engaged in care with 87% (3,126/3,585) of months fulfilling the definition of engaged in care.

CONCLUSIONS

The adapted algorithm allowed the varying clinical scenarios of YPLPHIV to be taken into account when measuring EIC. However availability of good quality surveillance data is crucial to ensure that EIC can be measured well.

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.

Social effects of HIV disclosure, an ongoing challenge in young adults living with perinatal HIV: a qualitative study

Introduction

Young adults with perinatal HIV (YAPHIV) have survived the long journey of life while living with HIV since early childhood. We explore the HIV disclosure experience and its social effects from their perspectives.

Methods

The qualitative study was conducted from June to November 2022 in Chiang Mai, Thailand. Data were collected through individual in-depth semi-structured interviews with 20 YAPHIV at the median age of 25 years. Content analysis was used to identify themes from the interview transcripts.

Results

Most participants learned their HIV status from their parents, caregivers, healthcare providers, or other people in community during their childhood. Some were disclosed later in adolescent years. HIV disclosure to others was associated with various experiences in different stages of life. While some YAPHIV decided not to disclose their HIV status to anyone, it also had social effects. Three major themes were identified: (1) positive social effects of HIV disclosure (perceived social acceptance, perceived social support); (2) negative social effects of HIV disclosure (effects on child rearing, schooling, and family relationship); and (3) HIV non-disclosure (anticipated stigma, negative effects on the quality of employment, and relationships). An emerging theme was a need for peer support mentioned by several YAPHIV as they would like to discuss with somebody and share their feelings while living with HIV.

Conclusion

HIV disclosure remains challenging for YAPHIV while growing up and moving toward adult milestones. Better understanding their situations and perspectives would allow healthcare providers to provide them with updated HIV knowledge, coping skills, and psychosocial support.

Mental Health, ART Adherence, and Viral Suppression Among Adolescents and Adults Living with HIV in South Africa: A Cohort Study

We followed adolescents and adults living with HIV aged older than 15 years who enrolled in a South African private-sector HIV programme to examine adherence and viral non-suppression (viral load > 400 copies/mL) of participants with (20,743, 38%) and without (33,635, 62%) mental health diagnoses. Mental health diagnoses were associated with unfavourable adherence patterns. The risk of viral non-suppression was higher among patients with organic mental disorders [adjusted risk ratio (aRR) 1.55, 95% confidence interval (CI) 1.22-1.96], substance use disorders (aRR 1.53, 95% CI 1.19-1.97), serious mental disorders (aRR 1.30, 95% CI 1.09-1.54), and depression (aRR 1.19, 95% CI 1.10-1.28) when compared with patients without mental health diagnoses. The risk of viral non-suppression was also higher among males, adolescents (15-19 years), and young adults (20-24 years). Our study highlights the need for psychosocial interventions to improve HIV treatment outcomes-particularly of adolescents and young adults-and supports strengthening mental health services in HIV treatment programmes.

Progress towards unique patient identification and case-based surveillance within the Southern African development community

Population mobility makes patient-tracking and care linkage in the South African Development Community (SADC) challenging. Case-based surveillance (CBS) through individual-level clinical data linked with a unique patient-identifier (UPI) is recommended. We conducted a mixed-methods landscape analysis of UPI and CBS implementation within selected SADC countries, this included: (1) SADC UPI implementation literature review; (2) assessment of UPI and CBS implementation for high HIV-prevalence SADC countries; (3) UPI implementation case-study in selected South African primary healthcare (PHC) facilities. Research into CBS and UPI implementation for the SADC region is lacking. Existing patient-identification methods often fail and limit patient-tracking. Paper-based records and poor integration between health-information systems further restrict patient-tracking. Most countries were in the early-middle stages of CBS and faced UPI challenges. Our South African case-study found that the UPI often goes uncaptured. Difficulties tracking patients across prevention and care cascades will continue until a functional and reliable UPI is available.

The Outcomes of Transition from Pediatrics to Adult Care among Adolescents and Young Adults with HIV at a Tertiary Care Center in Bangkok

Background: Adolescents and young adults with HIV (AYHIV) are at high-risk of loss to follow up and virologic failure, particularly during transition from pediatric to adult clinics. Methods: We reviewed the medical records of AYHIV to characterize retention and virologic suppression following their transition. Results: 101 AYHIV, 97% perinatally infected, were transferred at the median age of 20 (IQR: 19-21) years. At 1-year post-transition, 92.1% were retained in care and 73.3% had viral suppression and at 2-years the retention and viral suppression were 87.1% and 76.7%, respectively. Factors associated with viral suppression were transition at ≥ 20 years of age (aOR 4.38, 95% CI 1.41-13.65) and receiving first-line ART regimen, compared to second- or third-line regimens, at transition (aOR 6.05, 95% CI 1.55-23.58). Conclusion: Transition outcomes of AYHIV in our setting were suboptimal. There is a need for interventions to support AYHIV transition during this vulnerable period.

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.

Transfer of Patients on Antiretroviral Therapy Attending Primary Health Care Services in South Africa

BACKGROUND

Patients stable on antiretroviral therapy (ART) may require transfer between health care facilities to maintain continuous care, yet data on the frequency, predictors, and virologic outcomes of transfers are limited.

METHODS

Data for all viral load (VL) testing at public sector health facilities in the Western Cape Province (2011-2018) were obtained. Participant inclusion criteria were a first VL between 2011 and 2013, age >15 years at ART initiation, and >1 VL within 5 years of ART initiation, of which ≥1 was at a primary health care facility. Two successive VLs taken at different facilities indicated a transfer. We assessed predictors of transfer using generalized estimating equations with Poisson regression and the association between transfer and subsequent VL> 1000 copies/mL using generalized mixed effects.

RESULTS

Overall 84,814 participants (median age at ART initiation 34 years and 68% female) were followed up for up to 4.5 years after their first VL: 34% (n = 29,056) transferred at least once, and among these, 26% transferred twice and 11% transferred thrice or more. Female sex, age <30 years, and first VL > 1000 copies/mL were independently associated with an increased rate of transfer [adjusted rate ratio 1.24, 95% confidence interval (CI): 1.21 to 1.26; 1.34, 95% CI: 1.31 to 1.36; and 1.42, 95% CI: 1.38 to 1.45, respectively]. Adjusting for age, sex, and disengagement, transfer was associated with an increased relative odds of VL > 1000 copies/mL (odds ratio 1.35, 95% CI: 1.29 to 1.42).

CONCLUSIONS

Approximately one-third of participants transferred and virologic outcomes were poor post-transfer. Stable patients who transfer may require additional support to maintain adherence.

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.

Virologic non-suppression and early loss to follow up among pregnant and non-pregnant adolescents aged 15-19 years initiating antiretroviral therapy in South Africa: a retrospective cohort study

Introduction

Older adolescents aged 15–19 years continue to have high rates of loss to follow up (LTFU), and high rates of virologic non‐suppression (VNS) compared to younger adolescents and adults. Adolescent females are at risk of pregnancy, which puts those living with HIV at a dual vulnerability. Our study assessed the factors associated with VNS and LTFU in older adolescents (including pregnant females) who initiated antiretroviral therapy (ART) in South Africa.

Methods

We included adolescents aged 15–19 years initiating ART between 2004 and 2019, with ≥ one viral load (VL) measurement between 4 and 24.5 months, and ≥ 6 months follow‐up, from six South African cohorts of the International epidemiology Databases to Evaluate AIDS‐Southern Africa (IeDEA‐SA). We defined VNS as VL ≥400 copies/ml and LTFU as not being in care for ≥180 days from ART start and not known as transferred out of the clinic or dead in the first 24 months on ART. We examined factors associated with VNS and LTFU using Fine&Gray competing risk models.

Results

We included a total of 2733 adolescents, 415 (15.2%) males, median (IQR) age at ART start of 18.6 (17.3, 19.4) years. Among females, 585/2318 (25.2%) were pregnant. Over the 24‐month follow‐up, 424 (15.5%) of all adolescents experienced VNS: range (11.1% pregnant females and 20.5% males). Over half of all adolescents were LTFU before any other event could occur. The hazard of VNS reduced with increasing age and CD4 count above 200 cells/μl at ART initiation among all adolescents having adjusted for all measured patient characteristics [adjusted sub‐distribution hazard ratio (aSHR) 19 vs. 15 years: 0.50 (95% CI: 0.36, 0.68), aSHR: >500 vs. ≤200 cells/μl: 0.22 (95% CI: 0.16, 0.31)]. The effect of CD4 count persisted in pregnant females. Increasing age and CD4 count >200 cells/μl were risk factors for LTFU among all adolescents.

Conclusions

Older adolescents had a high risk of LTFU shortly after ART start and a low risk of VNS, especially those initiating treatment during pregnancy. Interventions addressing adherence and retention should be incorporated into adolescent‐friendly services to prevent VNS and LTFU and endeavour to trace lost adolescents as soon as they are identified.

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.

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.

Patient pathways of tuberculosis care-seeking and treatment: an individual-level analysis of National Health Insurance data in Taiwan

Introduction

Patients with tuberculosis (TB) often experience difficulties in accessing diagnosis and treatment. Patient pathway analysis identifies mismatches between TB patient care-seeking patterns and service coverage, but to date, studies have only employed cross-sectional aggregate data.

Methods

We developed an algorithmic approach to analyse and interpret patient-level routine data on healthcare use and to construct patients’ pathways from initial care-seeking to treatment outcome. We applied this to patients with TB in a simple random sample of one million patients’ records in the Taiwan National Health Insurance database. We analysed heterogeneity in pathway patterns, delays, service coverage and patient flows between different health system levels.

Results

We constructed 7255 pathways for 6258 patients. Patients most commonly initially sought care at the primary clinic level, where the capacity for diagnosing TB patients was 12%, before eventually initiating treatment at higher levels. Patient pathways are extremely heterogeneous prior to diagnosis, with the 10% most complex pathways accounting for 48% of all clinical encounters, and 55% of those pathways yet to initiate treatment after a year. Extended consideration of alternative diagnoses was more common for patients aged 65 years or older and for patients with chronic lung disease.

Conclusion

Our study demonstrates that longitudinal analysis of routine individual-level healthcare data can be used to generate a detailed picture of TB care-seeking pathways. This allows an understanding of several temporal aspects of care pathways, including lead times to care and the variability in patient pathways.

Clinical, Immunological, and Virological Outcomes Among Youths With Perinatal HIV After Transition to Adult Units in Spain From 1997 to 2016

BACKGROUND

Children living with HIV are reaching adulthood and transitioning to adult clinics. This study aimed to describe clinical and immunovirological status after transition in patients with perinatal HIV.

METHODS

Patients participating in the Spanish multicenter pediatric HIV cohort (CoRISpe) transferred to adult care (FARO cohort) from 1997 to 2016 were included. Clinical and immunovirological data were collected from 12 years old to the last follow-up moment after transition (up to December 2017). We used mixed-effect models to analyze changes in CD4 counts or viral suppression and multivariate analysis for risk factors for virological failure (VF) and immune status after transition. Transition years were classified into 5-year periods.

RESULTS

Three hundred thirty-two youths were included. The median age at transition was 18 years (interquartile range: 16.3-18.9) and 58.1% women. The median follow-up time after transition was 6.6 years (interquartile range: 4.6-9.8), and 11 patients (3.3%) died. The immunovirological status at transition improved over the last periods. Globally, VF decreased from 27.7% at transition to 14.4% at 3 years post-transition (P < 0.001), but no changes were observed in the last 2 transition periods. There were no significant differences in CD4 over the transition period. Risk factors for VF after transition were female sex, being born abroad and VF at transition, and for lower CD4 after transition were Romani heritage, younger age at transition, lower CD4 nadir, and CD4 at transition.

CONCLUSIONS

After transition, virological suppression improved in the early transition periods, and immunological status remained stable. Nevertheless, some patients had higher risk of worse outcomes. Identifying these patients may aid during transition.

"It was not okay because you leave your friends behind": A prospective analysis of transition to adult care for adolescents living with perinatally-acquired HIV in South Africa

OBJECTIVE

To determine facilitators and barriers to successful transition to adult care for adolescents living with perinatally-acquired HIV in South Africa.

METHODS

We prospectively enrolled 30 adolescents living with perinatally-acquired HIV after their pediatrician deemed them ready for transition to adult care but prior to their transition. Eighteen months after enrollment, we measured transition status, engagement in care (i.e., viral load within 12 months of transition), and viral suppression (<200 copies/ml). Additionally, we conducted in-depth interviews with adolescents before and after transition to explore facilitators and barriers to successful transition.

RESULTS

A total of 19/30 (63%) adolescents transitioned to adult care. Of those who transitioned, 11 (58%) were retained in care and 7 (37%) were virally suppressed one year after transition to adult care. Insufficient staff training, lack of availability of pediatric ART formulations in adult clinics, and insufficient clinical monitoring contributed to delayed transition. Rigid clinical scheduling that interfered with school and loss of clinic relationships with peers and clinical staff were major factors in contributing to poor engagement in care after transition. Maturity of the adolescent, reduced distance to clinic, and reduced length of time in the clinic were seen as facilitators to transition to adult care.

CONCLUSION

Improved preparation for transition by pediatric and adult clinical staff, including restructuring of care delivery, may improve successful transition of adolescents living with perinatally acquired HIV to adult care. Transition readiness assessments are needed to determine optimal timing of transition and which adolescents are ready to transition to adult care.

The HIV care cascade for adolescents initiated on antiretroviral therapy in a health district of South Africa: a retrospective cohort study

BACKGROUND

Little evidence exists to comprehensively estimate adolescent viral suppression after initiation on antiretroviral therapy in sub-Saharan Africa. This study examines adolescent progression along the HIV care cascade to viral suppression for adolescents initiated on antiretroviral therapy in South Africa.

METHODS

All adolescents ever initiated on antiretroviral therapy (n=1080) by 2015 in a health district of the Eastern Cape, South Africa, were interviewed in 2014-2015. Clinical records were extracted from 52 healthcare facilities through January 2018 (including records in multiple facilities). Mortality and loss to follow-up rates were corrected for transfers. Predictors of progression through the HIV care cascade were tested using sequential multivariable logistic regressions. Predicted probabilities for the effects of significant predictors were estimated by sex and mode of infection.

RESULTS

Corrected mortality and loss to follow-up rates were 3.3 and 16.9%, respectively. Among adolescents with clinical records, 92.3% had ≥1 viral load, but only 51.1% of viral loads were from the past 12 months. Adolescents on ART for ≥2 years (AOR 3.42 [95%CI 2.14-5.47], p< 0.001) and who experienced decentralised care (AOR 1.39 [95%CI 1.06-1.83], p=0.018) were more likely to have a recent viral load. The average effect of decentralised care on recent viral load was greater for female (AOR 2.39 [95%CI 1.29-4.43], p=0.006) and sexually infected adolescents (AOR 3.48 [95%CI 1.04-11.65], p=0.043). Of the total cohort, 47.5% were recorded as fully virally suppressed at most recent test. Only 23.2% were recorded as fully virally suppressed within the past 12 months. Younger adolescents (AOR 1.39 [95%CI 1.06-1.82], p=0.017) and those on ART for ≥2 years (AOR 1.70 [95%CI 1.12-2.58], p=0.013) were more likely to be fully viral suppressed.

CONCLUSIONS

Viral load recording and viral suppression rates remain low for ART-initiated adolescents in South Africa. Improved outcomes for this population require stronger engagement in care and viral load monitoring.

Transition from pediatric to adult care for adolescents living with HIV in South Africa: A natural experiment and survival analysis

OBJECTIVE

To determine rates of retention and viral suppression among adolescents living with perinatally-acquired HIV who remained in pediatric care compared to those who transitioned to adult care.

METHODS

We evaluated a natural experiment involving adolescents living with perinatally-acquired HIV who were attending a government-supported antiretroviral clinic in KwaZulu-Natal, South Africa. Prior to 2011, all adolescents transitioned to adult care at 12 years of age. Due to a policy change, all adolescents were retained in pediatric care after 2011. We analyzed adolescents two years before and two years after this policy change. Outcomes were retention in care and HIV viral suppression one year after transition to adult care or the 13th birthday if remaining in pediatric care.

RESULTS

In the natural experiment, 180 adolescents who turned 12 years old between 2011 and 2014 were evaluated; 35 (20%) transitioned to adult care under the old policy and 145 (80%) remained in pediatric care under the new policy. Adolescents who transitioned to the adult clinic had lower rates of retention in care (49%; 17/35) compared to adolescents remaining in the pediatric clinic (92%; 134/145; p<0.001). Retention in care was lower (ARR 0.59; 95%CI 0.43-0.82; p = 0.001) and viral suppression was similar (ARR = 1.06, 95%CI 0.89-1.26; p = 0.53) for adolescents who transitioned to adult care compared to adolescents remaining in pediatric care.

CONCLUSION

Adolescents living with perinatally-acquired HIV appear to have higher retention in care when cared for in pediatric clinics compared to adult clinics. Longer-term follow-up is needed to fully assess viral suppression.

Healthcare retention and clinical outcomes among adolescents living with HIV after transition from pediatric to adult care: a systematic review

Background

Adolescents living with HIV (ALWH) who transition from pediatric to adult care face several challenges that increase their risk of experiencing treatment interruptions and being lost to HIV care with resultant increased morbidity and mortality. To date, few studies have examined their outcomes post-healthcare transition (HCT), precluding the development and dissemination of evidence-based interventions aimed at retaining ALWH in HIV care both during and after HCT. We conducted a systematic review to synthesize the outcomes of ALWH post-HCT to provide suggestions for future directions.

Methods

We systematically searched several electronic databases through October 2019 using keywords for HIV, HCT and ALWH. We categorized studies by target population, country (i.e., upper-high income and low-middle income), study design (i.e., descriptive, mixed methods, quantitative), outcomes measured, and follow-up period.

Results

A total of 24 studies met inclusion criteria. Studies were categorized according to the following HCT outcomes: retention in HIV care post-HCT (n = 13), changes in CD4+ count and viral load post-HCT (n = 16), and mortality among ALWH post-HCT (n = 7). Most studies (n = 11) examining retention in HIV care indicated that more than 70% of ALWH were retained in care 1–2 years post-HCT while the remaining studies (n = 2) reported retention rates less than 55%. While studies indicated that CD4+ counts and viral loads tended to worsen during the first few years post-HCT, these differences were often not statistically significant. Among all ALWH who transitioned to adult care, a small proportion died within their first seven years post-HCT. Among qualitative studies, common themes included transition readiness (n = 6), provider-patient relationship in the adult clinic setting (n = 6), and concern about the adult clinic setting (n = 4).

Conclusions

Transition outcomes were poorest for ALWH with unsuppressed viremia pre-HCT, suggesting that this subgroup of ALWH may need greater support from their treatment teams and caregivers during and post-HCT to improve clinical outcomes.

International epidemiology databases to evaluate AIDS (IeDEA) in sub-Saharan Africa, 2012-2019

PURPOSE

The objectives of the International epidemiology databases to evaluate AIDS (IeDEA) are to (i) evaluate the delivery of combination antiretroviral therapy (ART) in children, adolescents and adults in sub-Saharan Africa, (ii) to describe ART regimen effectiveness, durability and tolerability, (iii) to examine HIV-related comorbidities and coinfections and (iv) to examine the pregnancy-related and HIV-related outcomes of women on ART and their infants exposed to HIV or ART in utero or via breast milk.

PARTICIPANTS

IeDEA is organised in four regions (Central, East, Southern and West Africa), with 240 treatment and care sites, six data centres at African, European and US universities, and almost 1.4 million children, adolescents and adult people living with HIV (PLWHIV) enrolled.

FINDINGS TO DATE

The data include socio-demographic characteristics, clinical outcomes, opportunistic events, treatment regimens, clinic visits and laboratory measurements. They have been used to analyse outcomes in PLWHIV-1 or PLWHIV-2 who initiate ART, including determinants of mortality, of switching to second-line and third-line ART, drug resistance, loss to follow-up and the immunological and virological response to different ART regimens. Programme-level estimates of mortality have been corrected for loss to follow-up. We examined the impact of coinfection with hepatitis B and C, and the epidemiology of different cancers and of (multidrug resistant) tuberculosis, renal disease and of mental illness. The adoption of 'Treat All', making ART available to all PLWHIV regardless of CD4+ cell count or clinical stage was another important research topic.

FUTURE PLANS

IeDEA has formulated several research priorities for the 'Treat All' era in sub-Saharan Africa. It recently obtained funding to set up sentinel sites where additional data are prospectively collected on cardiometabolic risks factors as well as mental health and liver diseases, and is planning to create a drug resistance database.

Long-term outcomes in perinatally HIV-infected adolescents and young adults on antiretroviral therapy: a review of South African and global literature

Paediatric antiretroviral programmes have been implemented globally for more than a decade, yet information on long-term treatment outcomes in perinatally HIV-infected adolescents is limited. Published literature on long-term treatment outcomes was reviewed, including virologic, immunologic and growth outcomes, as well as drug resistance and factors associated with drug resistance. Outcomes were compared between high-income countries and low- and middle-income countries (LMIC), with additional focus on South Africa, the country with the biggest HIV epidemic in the world and the largest treatment programme. Treatment outcomes varied but viral suppression results globally were generally concerning. No studies from LMIC have reported on outcomes after >10 years follow-up, demonstrating that further studies are needed.

Managing the transition from paediatric to adult care for HIV, Kenya

Expansion of access to diagnosis and treatment for human immunodeficiency virus (HIV) and a high incidence of HIV infection in adolescence has resulted in a growing population of adolescents and young adults living with HIV. The prevalence of poor retention in care, insufficient viral suppression and loss to follow-up are higher among adolescents and young adults compared with other age groups. Poor outcomes could be attributed to psychosocial changes during adolescence, but also to poor transitional care from paediatric to adult HIV services. In many countries, transition processes remain poorly defined and unstructured, which may jeopardize treatment adherence and retention. We describe existing definitions of transition and transition frameworks, and key elements of transition as proposed by key national stakeholders in Kenya. Our consensus definition of transition is "a planned process by which adolescents and young adults living with HIV, and their caregivers, are empowered with knowledge and skills to enable them to independently manage their health." Transition should begin soon after disclosure of HIV status until an adolescent gains the necessary knowledge and skills and is willing to move to adult services, or by 25 years of age. Proposed key elements of transition are: target ages for milestone achievement; readiness assessment; caregiver involvement and communication with adult clinics; flexibility to return to adolescent or paediatric clinics; group transition; and considerations for adolescents with special needs. Retention in care, linkage to care and viral suppression are important markers of transition success. Proposed definitions and key elements could provide a framework for structuring transition programmes in other countries.

Simulation Modeling and Metamodeling to Inform National and International HIV Policies for Children and Adolescents

Objective and Approach:

Computer-based simulation models serve an important purpose in informing HIV care for children and adolescents. We review current model-based approaches to informing pediatric and adolescent HIV estimates and guidelines.

Findings:

Clinical disease simulation models and epidemiologic models are used to inform global and regional estimates of numbers of children and adolescents living with HIV and in need of antiretroviral therapy, to develop normative guidelines addressing strategies for diagnosis and treatment of HIV in children, and to forecast future need for pediatric and adolescent antiretroviral therapy formulations and commodities. To improve current model-generated estimates and policy recommendations, better country-level and regional-level data are needed about children living with HIV, as are improved data about survival and treatment outcomes for children with perinatal HIV infection as they age into adolescence and adulthood. In addition, novel metamodeling and value of information methods are being developed to improve the transparency of model methods and results, as well as to allow users to more easily tailor model-based analyses to their own settings.

Conclusions:

Substantial progress has been made in using models to estimate the size of the pediatric and adolescent HIV epidemic, to inform the development of guidelines for children and adolescents affected by HIV, and to support targeted implementation of policy recommendations to maximize impact. Ongoing work will address key limitations and further improve these model-based projections.

Using Observational Data to Inform HIV Policy Change for Children and Youth

Observational data characterizing the pediatric and adolescent HIV epidemics in real-world settings are critical to informing clinical guidelines, governmental HIV programs, and donor prioritization. Global expertise in curating and analyzing these data has been expanding, with increasingly robust collaborations and the identification of gaps in existing surveillance capacity. In this commentary, we describe existing sources of observational data for children and youth living with HIV, focusing on larger regional and global research cohorts, and targeted surveillance studies and programs. Observational data are valuable resources to cross-validate other research and to monitor the impact of changing HIV program policies. Observational studies were among the first to highlight the growing population of children surviving perinatal HIV and transitioning to adolescence and young adulthood, and have raised serious concerns about high rates of treatment failure, loss to follow-up, and death among older perinatally infected youth. The use of observational data to inform modeling of the current global epidemic, predict future patterns of the youth cascade, and facilitate antiretroviral forecasting are critical priorities and key end products of observational HIV research. Greater investments into data infrastructure are needed at the local level to improve data quality and at the global level to faciliate reliable interpretation of the evolving patterns of the pediatric and youth epidemics. Although this includes harmonized data forms, use of unique patient identifiers to allow for data linkages across routine data sets and electronic medical record systems, and competent data managers and analysts are essential to make optimal use of the data collected.

Transition Pathways Out of Pediatric Care and Associated HIV Outcomes for Adolescents Living With HIV in South Africa

BACKGROUND

Research on adolescent transitions out of pediatric HIV care has focused on high-income countries, with limited understanding of transitions in sub-Saharan Africa's public health sector.

METHODS

Patient file data were extracted through December 2017 for all 10- to 19-year olds ever initiated on antiretroviral therapy in a health district of the Eastern Cape, South Africa (n = 951). Pathways in HIV care were identified by tracing movements across facility care types and levels. Associations between pathways and viral failure, mortality, loss to follow-up, and viral load change were tested in sequential multivariable regressions. Analyses controlled for sociodemographic and treatment-related variables. Thematic analyses of semistructured health care provider interviews identified transition support at included facilities.

RESULTS

Only 57.8% of adolescents had initiated antiretroviral therapy in pediatric care, and 20.4% of the total cohort had transitioned out of pediatric HIV care. Among the 42.2% who had initiated in nonpediatric care, 93.8% remained exclusively in nonpediatric care. Median age at first transition was 14 years. Two main pathways were identified: classical transition to adult HIV care (43.3%) and down referral transition to primary health care clinics (56.7%). Across pathways, 27.3% experienced cyclical transition or repeated movement between pediatric and nonpediatric care. Independent of covariates, adolescents with down referral transition were less likely to demonstrate viral failure (adjusted odds ratio, 0.21; 95% confidence interval: 0.10 to 0.42; P < 0.001). Mortality and loss to follow-up were not associated with either pathway. Median posttransition viral load change was not clinically significant (median, 0.00; interquartile range: 0.00-0.35) or associated with transition pathways. Health care providers described informal "protocols" for mitigating risk of negative posttransition HIV outcomes.

CONCLUSIONS

This study proposes a contextually relevant model for transitions out of pediatric HIV care in South Africa. Feasible, scalable "protocols" may mitigate risk of worsening posttransition HIV outcomes.

Barriers to Retention in Care are Overcome by Adolescent-Friendly Services for Adolescents Living with HIV in South Africa: A Qualitative Analysis

To assess facilitators and barriers to retention in care for adolescents living with HIV, we conducted in-depth, semi-structured interviews with adolescents ages 13 to 24 years who were living with HIV and being cared for in either an adolescent-friendly or standard government-supported clinic in KwaZulu-Natal, South Africa. We used inductive content analysis approach based on grounded theory derived from reviewing, coding, and interpreting data. We interviewed 28 adolescents living with HIV (16 in the adolescent clinic and 12 from the pediatric clinic) and 14 of their caregivers. Barriers to retention in care included having to attend clinic during school hours, fear of disclosure to others, social isolation, and conflict with clinical staff. Facilitators to retention in care seen in the adolescent-friendly services clinic included after school clinic hours, peer support, and connection to the clinical staff. Adolescent-friendly services are facilitators of HIV care and warrant prioritization in treatment programs.

Retention and adherence: global challenges for the long-term care of adolescents and young adults living with HIV

PURPOSE OF REVIEW

Adolescents living with HIV are the only age group with increasing HIV mortality at a time of global scale-up of access to antiretroviral therapy (ART). As a 'treat all' strategy is implemented worldwide, it is critically important to optimize retention and adherence for this vulnerable group.

RECENT FINDINGS

Adolescents and young adults living with HIV have poorer outcomes when compared with adults at each stage of the HIV care cascade, irrespective of income setting. Rates of viral suppression are lowest for adolescents living with HIV, and adherence to ART remains an enormous challenge. High-quality studies of interventions to improve linkage to, and retention in, care on suppressive ART are starkly lacking for adolescents and young adults living with HIV across the globe. However, examples of good practice are beginning to emerge but require large-scale implementation studies with outcome data disaggregated by age, route of infection, and income setting, and include young pregnant women and key populations groups.

SUMMARY

There is an urgent need for evidence-based interventions addressing gaps in the adolescent HIV care cascade, including supporting retention in care and adherence to ART.

Cancer in adolescents and young adults living with HIV

PURPOSE OF REVIEW

Adults living with HIV have an increased risk of malignancy yet there is little data for adolescents and young adults. We reviewed recently published cancer epidemiology, treatment, and outcome data for adolescents and young adults living with HIV (AYALHIV) aged 10 to less than 25 years between 2016 and 2017.

RECENT FINDINGS

AYALHIV are at increased risk of developing cancer compared to their uninfected peers. Kaposi sarcoma and non-Hodgkin lymphoma occur most frequently with variation by geographical region. Increased cancer risk is associated with HIV-related immunosuppression and coinfection with oncogenic viruses. Published data, particularly on posttreatment outcomes, remain limited and analyses are hampered by lack of data disaggregation by age and route of HIV transmission.

SUMMARY

Although data are sparse, the increased cancer risk for AYALHIV is the cause for concern and must be modified by improving global access and uptake of antiretroviral therapy, human papilloma virus (HPV) and hepatitis B virus (HBV) vaccination, screening for hepatitis B and C infection, and optimized cancer screening programs. Education aimed at reducing traditional modifiable cancer risk factors should be embedded within multidisciplinary services for AYALHIV.

Growing up with perinatal HIV

: The World Health Organization estimates that over four million children have been infected with HIV, most via perinatal transmission. The availability of safe and effective antiretroviral therapy (ART) has radically reduced mortality in this population and most that have access to ART are now thriving. However, long-term effects of HIV infection and its therapy have significant impact on aging adolescents and young adults with perinatal HIV infection. Many of the complications of long-term HIV infection seen in adults are also present, although the main impact of long-standing HIV infection and its treatment in children has been on growth and development, including neurodevelopment. A better understanding of the complexities of growing up with perinatal HIV will help prepare low and middle-income countries of the world where ART is now available to successfully manage their aging up populations of adolescents and young adults with perinatal HIV infection.

Mortality and losses to follow-up among adolescents living with HIV in the IeDEA global cohort collaboration

INTRODUCTION

We assessed mortality and losses to follow-up (LTFU) during adolescence in routine care settings in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium.

METHODS

Cohorts in the Asia-Pacific, the Caribbean, Central, and South America, and sub-Saharan Africa (Central, East, Southern, West) contributed data, and included adolescents living with HIV (ALHIV) enrolled from January 2003 and aged 10 to 19 years (period of adolescence) while under care up to database closure (June 2016). Follow-up started at age 10 years or the first clinic visit, whichever was later. Entering care at <15 years was a proxy for perinatal infection, while entering care ≥15 years represented infection acquired during adolescence. Competing risk regression was used to assess associations with death and LTFU among those ever receiving triple-drug antiretroviral therapy (triple-ART).

RESULTS

Of the 61,242 ALHIV from 270 clinics in 34 countries included in the analysis, 69% (n = 42,138) entered care <15 years of age (53% female), and 31% (n = 19,104) entered care ≥15 years (81% female). During adolescence, 3.9% died, 30% were LTFU and 8.1% were transferred. For those with infection acquired perinatally versus during adolescence, the four-year cumulative incidences of mortality were 3.9% versus 5.4% and of LTFU were 26% versus 69% respectively (both p < 0.001). Overall, there were higher hazards of death for females (adjusted sub-hazard ratio (asHR) 1.19, 95% confidence interval (CI) 1.07 to 1.33), and those starting treatment at ≥5 years of age (highest asHR for age ≥15: 8.72, 95% CI 5.85 to 13.02), and in care in mostly urban (asHR 1.40, 95% CI 1.13 to 1.75) and mostly rural settings (asHR 1.39, 95% CI 1.03 to 1.87) compared to urban settings. Overall, higher hazards of LTFU were observed among females (asHR 1.12, 95% CI 1.07 to 1.17), and those starting treatment at age ≥5 years (highest asHR for age ≥15: 11.11, 95% CI 9.86 to 12.53), in care at district hospitals (asHR 1.27, 95% CI 1.18 to 1.37) or in rural settings (asHR 1.21, 95% CI 1.13 to 1.29), and starting triple-ART after 2006 (highest asHR for 2011 to 2016 1.84, 95% CI 1.71 to 1.99).

CONCLUSIONS

Both mortality and LTFU were worse among those entering care at ≥15 years. ALHIV should be evaluated apart from younger children and adults to identify population-specific reasons for death and LTFU.

Traversing the cascade: urgent research priorities for implementing the 'treat all' strategy for children and adolescents living with HIV in sub-Saharan Africa

Children and adolescents living with HIV (CALHIV) in sub-Saharan Africa experience significant morbidity and alarmingly high mortality rates due to critical gaps in the HIV care cascade, including late diagnosis and initiation of treatment, as well as poor retention in care and adherence to treatment. Interventions to strengthen the adult HIV care cascade may not be as effective in improving the cascade for CALHIV, for whom specific strategies are needed. Particular attention needs to be paid to the contexts of sub-Saharan Africa, where more than 85% of the world's CALHIV live. Implementing the 'treat all' strategy in sub-Saharan Africa requires dedicated efforts to address the unique diagnosis and care needs of CALHIV, in order to improve paediatric and adolescent outcomes, prevent viral resistance and reduce the number of new HIV infections. We consider the UNAIDS 90-90-90 targets from the perspective of infants, children and adolescents, and discuss the key challenges, knowledge gaps and urgent research priorities for CALHIV in implementation of the 'treat all' strategy in sub-Saharan Africa.

Adolescent pregnancy at antiretroviral therapy (ART) initiation: a critical barrier to retention on ART

INTRODUCTION

Adolescence and pregnancy are potential risk factors for loss to follow-up (LTFU) while on antiretroviral therapy (ART). We compared adolescent and adult LTFU after ART initiation to quantify the impact of age, pregnancy, and site-level factors on LTFU.

METHODS

We used routine clinical data for patients initiating ART as young adolescents (YA; 10 to 14 years), older adolescents (OA; 15 to 19 years) and adults (≥20 years) from 2000 to 2014 at 52 health facilities affiliated with the International epidemiology Databases to Evaluate AIDS (IeDEA) East Africa collaboration. We estimated cumulative incidence (95% confidence interval, CI) of LTFU (no clinic visit for ≥6 months after ART initiation) and identified patient and site-level correlates of LTFU, using multivariable Cox proportional hazards models for all patients as well as individual age groups.

RESULTS

A total of 138,387 patients initiated ART, including 2496 YA, 2955 OA and 132,936 adults. Of these, 55%, 78% and 66%, respectively, were female and 0.7% of YA, 22.3% of OA and 8.3% of adults were pregnant at ART initiation. Cumulative incidence of LTFU at five years was 26.6% (24.6 to 28.6) among YA, 44.1% (41.8 to 46.3) among OA and 29.3% (29.1 to 29.6) among adults. Overall, compared to adults, the adjusted hazard ratio, aHR, (95% CI) of LTFU for OA was 1.54 (1.41 to 1.68) and 0.77 (0.69 to 0.86) for YA. Compared to males, pregnant females had higher hazard of LTFU, aHR 1.20 (1.14 to 1.27), and nonpregnant women had lower hazard aHR 0.90 (0.88 to 0.93). LTFU hazard among the OA was primarily driven by both pregnant and nonpregnant females, aHR 2.42 (1.98 to 2.95) and 1.51 (1.27 to 1.80), respectively, compared to men. The LTFU hazard ratio varied by IeDEA program. Site-level factors associated with overall lower LTFU hazard included receiving care in tertiary versus primary-care clinics aHR 0.61 (0.56 to 0.67), integrated adult and adolescent services and food ration provision aHR 0.93 (0.89 to 0.97) versus nonintegrated clinics with food ration provision, having patient support groups aHR 0.77 (0.66 to 0.90) and group adherence counselling aHR 0.61 (0.57 to 0.67).

CONCLUSIONS

Older adolescents experienced higher risk of LTFU compared to YA and adults. Interventions to prevent LTFU among older adolescents are critically needed, particularly for female and/or pregnant adolescents.

Pediatric to adult healthcare transitioning for adolescents living with HIV in Nigeria: A national survey

Introduction

The period of transition from pediatric to adult care has been associated with poor health outcomes among 10–19 year old adolescents living with HIV (ALHIV). This has prompted a focus on the quality of transition services, especially in high ALHIV-burden countries. Due to lack of guidelines, there are no healthcare transition standards for Nigeria’s estimated 240,000 ALHIV. We conducted a nationwide survey to characterize routine transition procedures for Nigerian ALHIV.

Materials and methods

This cross-sectional survey was conducted at public healthcare facilities supported by five local HIV service implementing partners. Comprehensive HIV treatment facilities with ≥1 year of HIV service provision and ≥20 ALHIVs enrolled were selected. A structured questionnaire assessed availability of treatment, care and transition services for ALHIV. Transition was defined as a preparatory process catering to the medical, psychosocial, and educational needs of adolescents moving from pediatric to adult care. Comprehensive transition services were defined by 6 core elements: policy, tracking and monitoring, readiness evaluation, planning, transfer of care, and follow-up.

Results

All 152 eligible facilities were surveyed and comprised 106 (69.7%) secondary and 46 (30.3%) tertiary centers at which 17,662 ALHIV were enrolled. The majority (73, 48.3%) of the 151 facilities responding to the “clinic type” question were family-centered and saw all clients together regardless of age. Only 42 (27.8%) facilities had an adolescent-specific HIV clinic; 53 (35.1%) had separate pediatric/adolescent and adult HIV clinics, of which 39 (73.6%) reported having a transfer/transition policy. Only 6 (15.4%) of these 39 facilities reported having a written protocol. There was a bimodal peak at 15 and 18 years for age of ALHIV transfer to adult care. No surveyed facility met the study definition for comprehensive transition services.

Conclusions

Facilities surveyed were more likely to have non-specialized HIV treatment services and had loosely-defined, abrupt transfer versus transition practices, which lacked the core transition elements. Evidence-based standards of transitional care tailored to non-specialized HIV treatment programs need to be established to optimize transition outcomes among ALHIV in Nigeria and in similar settings.

Adolescent transition among young people with perinatal HIV in high-income and low-income settings

PURPOSE OF REVIEW

To summarize evidence for health outcomes among adolescents and young people living with HIV (AYLHIV) who have transitioned to adult care/adulthood, views of AYLHIV and providers on the transition process, and the effect of adolescent and youth friendly services (AYFS) on outcomes.

RECENT FINDINGS

A total of 43 studies were identified [n = 13 high-income countries (HICs), n = 30 low-/middle-income countries (LMICs)]. In HICs, around 75% of patients were retained in care at approximately 4 years posttransition. In LMICs, retention worsened from older adolescence into young adulthood. Across both contexts, comparisons of mortality, immunological, and virological outcomes were hampered by a limited number of studies and/or different definitions and study durations. AYLHIV and providers reported several factors that could aid transition and AYFS had generally positive outcomes.

SUMMARY

Overall, outcomes varied by study and context; direct comparison was severely hampered by the inclusion of different populations of AYLHIV (sometimes with small numbers and a lack of comparison groups), the use of different outcome definitions, varying follow-up duration, and the lack of a specific transition process in LMICs. Future studies need to consider harmonizing definitions and implementing unique patient identifiers, and data linkage techniques to improve the evidence base on long-term outcomes.

Higher retention and viral suppression with adolescent-focused HIV clinic in South Africa

Objective

To determine retention in care and virologic suppression among HIV-infected adolescents and young adults attending an adolescent-friendly clinic compared to those attending the standard pediatric clinic at the same site.

Design

Retrospective cohort analysis.

Setting

Government supported, hospital-based antiretroviral clinic in KwaZulu-Natal, South Africa.

Participants

Two hundred forty-one perinatally HIV-infected adolescents and young adults aged 13 to 24 years attending an adolescent-friendly clinic or the standard pediatric clinic from April 2007 to November 2015.

Intervention

Attendance in an adolescent-friendly clinic compared to a standard pediatric clinic.

Outcomes measures

Retention in care defined as one clinic visit or pharmacy refill in the prior 6 months; HIV-1 viral suppression defined as < 400 copies/ml.

Results

Overall, among 241 adolescents and young adults, retention was 89% (214/241) and viral suppression was 81% (196/241). Retention was higher among those attending adolescent clinic (95%) versus standard pediatric clinic (85%; OR 3.7; 95% confidence interval (CI) 1.2–11.1; p = 0.018). Multivariable logistic regression adjusted for age at ART initiation, gender, pre-ART CD4 count, months on ART, and tuberculosis history indicated higher odds of retention in adolescents and young adults attending adolescent compared to standard clinic (AOR = 8.5; 95% CI 2.3–32.4; p = 0.002). Viral suppression was higher among adolescents and young adults attending adolescent (91%) versus standard pediatric clinic (80%; OR 2.5; 95% CI 1.1–5.8; p = 0.028). A similar multivariable logistic regression model indicated higher odds of viral suppression in adolescents and young adults attending adolescent versus standard pediatric clinic (AOR = 3.8; 95% CI 1.5–9.7; p = 0.005).

Conclusion

Adolescents and young adults attending an adolescent-friendly clinic had higher retention in care and viral suppression compared to adolescents attending the standard pediatric clinic. Further studies are needed to prospectively assess the impact of adolescent-friendly services on these outcomes.
