Transition from paediatric to adult care of adolescents living with HIV in sub-Saharan Africa: challenges, youth-friendly models, and outcomes

An interprofessional model of care for adolescents with perinatal HIV: A qualitative study

Background and Aims

The number of perinatally HIV-infected adolescents (PHIVA) is increasing however many health care systems are not prepared for this population and their health challenges, specifically a model of care (MoC) is lacking. Thus the objective of this study was to develop and propose a MoC for PHIVA.

Methods

Through a qualitative study design, a MoC was developed and ratified with two focus groups, consisting of PHIVA and healthcare professionals.

Results

Seven participants were included in each focus group and the following themes were developed: relatable attributes; missing components; implementation and suggestions. Changes were made to the drafts of the MoC in response to the focus group results, leading to the finalisation of a MoC for PHIVA. The MoC focused on the importance of interprofessional health care and addressed the physical sequelae that PHIVA are likely to encounter. A schematic of the MoC was created for the use in general public education.

Conclusion

It is important that healthcare facilities are equipped to handle the specific needs of PHIVA. The interprofessional MoC developed in this study helps to address the requirements of this population.

A qualitative analysis of self-management needs of adolescents and young adults living with perinatally acquired HIV in rural, southwestern Uganda

The number of adolescents living with HIV remains high in sub-Saharan Africa with poorer HIV treatment outcomes among adolescents and young adults compared to individuals in other age groups. For adolescents and young adults living with perinatally acquired HIV (AYLPHIV), the transition from pediatric to adult HIV care is a particularly high-risk period. We conducted a qualitative study to understand self-management needs of AYLPHIV in rural, southwestern Uganda as they prepare to transition to adult HIV care in order to inform relevant interventions that can enable AYLPHIV acquire the necessary skills to manage their illness as they age into adulthood. We conducted 60 in-depth interviews with AYLPHIV (n = 30), caregivers (n = 20) and health care providers (n = 10) from the HIV clinic at Mbarara Regional Referral Hospital. We used an interview guide that focused on perceptions about transition to adult HIV care, challenges with transitioning, navigating HIV care, and self-management needs for AYLPHIV (from the perspectives of AYLPHIV, their caregivers, and health care providers). We used thematic analysis to identify themes related to AYLPHIV's self-management skills. We identified several self-management needs that we grouped under two major themes; social support and empowerment for AYLPHIV to assume responsibility for their own health and to navigate adult HIV care independently. The sub-themes under social support were information support, instrumental support, and emotional support as the sub themes while sub-themes under empowerment included self-advocacy skills, interpersonal skills, self-care skills, and disclosure skills. Taken together, these findings indicate that AYLPHIV need to be supported and empowered to maximize their chances of successfully transitioning to adult HIV care. Support comes from peers and caregivers. AYLPHIV require knowledge about their HIV status and empowerment with different skills including: self-advocacy skills, interpersonal skills, self-care skills, and HIV status disclosure skills, in order to assume responsibilities related to independent HIV care.

Layered vulnerability and researchers' responsibilities: learning from research involving Kenyan adolescents living with perinatal HIV infection

BACKGROUND

Carefully planned research is critical to developing policies and interventions that counter physical, psychological and social challenges faced by young people living with HIV/AIDS, without increasing burdens. Such studies, however, must navigate a 'vulnerability paradox', since including potentially vulnerable groups also risks unintentionally worsening their situation. Through embedded social science research, linked to a cohort study involving Adolescents Living with HIV/AIDS (ALH) in Kenya, we develop an account of researchers' responsibilities towards young people, incorporating concepts of vulnerability, resilience, and agency as 'interacting layers'.

METHODS

Using a qualitative, iterative approach across three linked data collection phases including interviews, group discussions, observations and a participatory workshop, we explored stakeholders' perspectives on vulnerability and resilience of young people living with HIV/AIDS, in relation to home and community, school, health care and health research participation. A total of 62 policy, provider, research, and community-based stakeholders were involved, including 27 ALH participating in a longitudinal cohort study. Data analysis drew on a Framework Analysis approach; ethical analysis adapts Luna's layered account of vulnerability.

RESULTS

ALH experienced forms of vulnerability and resilience in their daily lives in which socioeconomic context, institutional policies, organisational systems and interpersonal relations were key, interrelated influences. Anticipated and experienced forms of stigma and discrimination in schools, health clinics and communities were linked to actions undermining ART adherence, worsening physical and mental health, and poor educational outcomes, indicating cascading forms of vulnerability, resulting in worsened vulnerabilities. Positive inputs within and across sectors could build resilience, improve outcomes, and support positive research experiences.

CONCLUSIONS

The most serious forms of vulnerability faced by ALH in the cohort study were related to structural, inter-sectoral influences, unrelated to study participation and underscored by constraints to their agency. Vulnerabilities, including cascading forms, were potentially responsive to policy-based and interpersonal actions. Stakeholder engagement supported cohort design and implementation, building privacy, stakeholder understanding, interpersonal relations and ancillary care policies. Structural forms of vulnerability underscore researchers' responsibilities to work within multi-sectoral partnerships to plan and implement studies involving ALH, share findings in a timely way and contribute to policies addressing known causes of vulnerabilities.

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.

Transition of adolescents living with HIV from pediatric to adult care, a retrospective 12-year Single Center Study from the Sahel Region in West-Africa

ABSTRACTTransition is the next major hurdle in the field of HIV-infected youth, especially in sub-Saharan Africa. At St Camille Hospital in Ouagadougou, fully informed and compliant patients over 13-years-old were eligible for referral to the adult HIV/AIDS service, after completion of an individualized preparatory process. Transition consisted in at least two consecutive "joined-service" appointments in the respective facilities. We retrospectively compared immunological, clinical, and therapeutical data one year before transition, at transition and one year after transition. Between 2008 and 2019 73 patients (34 females, 39 males) were transitioned. All had been previously in pediatric care for at least 1 year and 66 were on HAART. Matched paired analysis of CD4 counts revealed a modest drop in CD4 cells over time (p < 0.05). Clinical data also showed strong fluctuation between WHO clinical stages over the three time points, with a clear trend towards increased severity especially post transfer. This large retrospective 12-year single-center experience from a Sahel country showed a 95.8% retention rate at one year. It demonstrates how a comprehensive plan, carefully implemented, can provide excellent retention, even in a low-resource setting. However, mild immunological decline was associated with a worrisome clinical deterioration, underlining the importance of assessing the latter after transition.

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.

Influences on decision-making about disclosure of HIV status by adolescents and young adults living with HIV in KwaZulu-Natal, South Africa

Background: Adolescents and young adults living with HIV (AYA) are faced with the challenge of living with a life-long chronic condition. We investigated the influences on the decisions by AYA to disclose their HIV status to family, intimate partners and friends.Methods: Twenty AYA aged between 15 and 24 years were purposely selected through local community-based organisations in eThekwini municipality and uMkhanyakude district in KwaZulu-Natal Province, South Africa. Virtual in-depth interviews were conducted between September 2020 to October 2021 using a topic guide focusing on HIV-status disclosure and the impact of stigma on decision-making capacity. An iterative thematic process was used for analysis.Results: Findings revealed the challenges that AYA experience for disclosure because of stigma and how this impacts their decision-making capacity. Family and friends influenced AYA in processing their discovery of their HIV status offering support needed to manage living with HIV. However, for some AYA disclosing to relatives, friends and intimate partners was difficult because of fears of rejection and recrimination. The act of disclosure was influenced by both internalised and external stigma and the type of relationships and interactions that AYA had with relatives, friends and caregivers.Conclusions: The decision to disclose is challenging for AYA because of the fear of rejection, along with internal and external stigma. The provision of support, whether from family or peers, is important. Enhancing the decision-making capacity of AYA is essential for developing their self-esteem as well as supporting future healthcare choices.

Factors influencing the transition from paediatric to adult HIV care in the Western Cape, South Africa: perspectives of health care providers

Transitioning to adult care for HIV-infected adolescents is a critical process in determining long-term health outcomes. Poor transitioning to adult care can lead to several adverse HIV-related outcomes for adolescents living with HIV, including disruption of care, non-adherence to ART and virological failure. In this qualitative study, we explore the barriers to and facilitators of the transition to adult care among HIV-infected youth from the perspectives of health care workers and allied staff. We enrolled 24 health care workers and allied staff from two infectious diseases clinics in the Western Cape of South Africa. Participants took part in a once-off, semi-structured interview that was conducted face-to-face at the respective clinics. Interviews were audio-recorded and transcribed verbatim for thematic analysis using ATLAS.ti. Two superordinate themes and seven subthemes emerged from the data. We found that barriers to the transition process were related to a lack of preparedness and readiness to transition at both an institutional level and at the level of the caregiver and adolescent. At the institutional level, a lack of a transition policy and limited time and resources available for the transition process were salient barriers. At the caregiver-adolescent level, adolescents' desire for normality and caregivers' reluctance to devolve responsibility of care to their children were important barriers to the transition process. Facilitators prepare adolescents and caregivers for transition from an early age. Our findings highlight the importance of considering both adolescent, caregiver and institutional factors when preparing for the transition process. Our findings also show that pressure on the health care system precludes the time required for this process. However, counselling for transition from an early age might be an important way to negate these issues.

Gen Z and HIV-Strategies for Optimizing the Care of the Next Generation of Adolescents Living with HIV

The management of adolescents living with HIV represents a particular challenge in the global response to HIV. The challenges specific to this age group include difficulties engaging and maintaining them in care, challenges with transition to adult care, and limited therapeutic options for treatment-experienced patients, all of which have been jeopardized by the COVID-19 pandemic. This paper summarizes some of the challenges in managing adolescents living with HIV, as well as some of the most recent and innovative therapeutic approaches in this population.

Impact of a teen club model on HIV outcomes among adolescents in rural Neno district, Malawi: a retrospective cohort study

OBJECTIVE

To compare the impact of a teen club model to the standard care model on HIV treatment outcomes among adolescents (10-19 years of age).

DESIGN

Retrospective cohort study.

SETTING

HIV clinics in Neno district, Malawi.

PARTICIPANTS

Adolescents living with HIV enrolled in teen clubs (n=235) and matched participants in standard HIV care (n=297).

OUTCOME MEASURES

Attrition from HIV care, defined as a combination of treatment outcomes 'died', 'defaulted' and 'transferred out'.

RESULTS

Over a 4-year follow-up period, adolescents who participated in the teen club had a significantly higher likelihood of remaining in care than those who did not (HR=2.80; 95% CI: 1.46 to 5.34). Teen clubs also increased the probability of having a recent measured viral load (VL) and BMI, but did not change the probability of VL suppression. The age at antiretroviral treatment initiation below 15 years (aHR=0.37; 95% CI: 0.17 to 0.82) reduced the risk of attrition from HIV care, while underweight status (aHR=3.18; 95% CI: 1.71 to 5.92) increased the risk of attrition, after controlling for sex, WHO HIV staging and teen club participation.

CONCLUSIONS

The teen club model has the potential to improve treatment outcomes among adolescents in rural Neno district. However, in addition to retaining adolescents in HIV care, greater attention is needed to treatment adherence and viral suppression in this special population. Further understanding of the contextual factors and barriers that adolescents in rural areas face could further improve the teen club model to ensure high-quality HIV care and quality of life.

'They should show them love even if their status of being HIV positive is known': Youth and caregiver stigma experience and strategies to end HIV stigma in schools

OBJECTIVE

HIV stigma and discrimination is widespread in sub-Saharan Africa and is associated with poor clinical outcomes. Schools play a critical role in the life of youth and have been identified as a potentially stigmatising environment. We sought to explore school HIV stigma drivers, facilitators, manifestations and outcomes among youth living with HIV (YLH) as well as potential stigma reduction interventions in Kenya.

METHODS

Semi-structured in-depth qualitative interviews with 28 school-attending YLH aged 14-19 years and 24 caregivers of YLH were analysed using directed content analysis. Results were summarised using the Health and Stigma Framework.

RESULTS

Drivers and facilitators of HIV stigma in the school environment included misconceptions about HIV transmission, HIV treatment outcomes and long-term overall health of people living with HIV. HIV stigma manifested largely as gossip, isolation and loss of friendships. Fear of HIV stigma or experienced stigma resulted in poor adherence to antiretroviral treatment-particularly among YLH in boarding schools-and poor mental health. Stigma also impacted school choice (boarding vs. day school) and prevented HIV disclosure to schools which was necessary for optimal support for care. Proposed interventions to address HIV stigma in schools included HIV education, psychosocial support for YLH, support for HIV disclosure to schools while ensuring confidentiality and building YLH resilience.

CONCLUSION

There is an urgent need to develop interventions to address HIV stigma in schools to ensure optimised health and social outcomes for YLH. Future studies to understand the most effective and efficient interventions are needed.

Growing Up with HIV: Experiences of Transition from Adolescence to Adulthood at Selected Primary Health Facilities in Limpopo Province, South Africa

BACKGROUND

Many children who contracted Human Immunodeficiency Virus (HIV) through vertical transmission are now in their adolescent and early adult years. The aim was to explore the experiences of adolescents living with HIV (ALWHIV) during the transition from childhood to adulthood.

METHODS AND MATERIAL

The study was conducted at selected primary healthcare facilities in the Mopani and Vhembe districts in July 2021. A qualitative research approach that included contextual, descriptive, and exploratory designs was used. The population comprised 27 ALWHIV who were purposively sampled and enrolled for ART care. Data were collected using in-depth interviews, and the question was "How is it for you as you live with a virus and transit from adolescent to adulthood". The open coding approach was used to analyse the data. Measures to ensure trustworthiness articulated in Lincoln and Guba's criteria and ethical considerations were adhered to.

FINDINGS

The findings revealed four themes: poor understanding of the disease condition, improved physical health when adhering to ARV treatments, challenges related to sexual maturity and intimate relationships, and parents not disclosing their children's HIV status.

CONCLUSION

Parents' delayed and non-disclosure of adolescents' positive HIV status led to a lack of awareness about the course of the disease, non-adherence to ART, and unsafe sex practices that could increase the risk of HIV transmission and re-infection. To address these multiple obstacles associated with ALWHIV, a comprehensive, multi-sectoral approach that is teenager-friendly should be undertaken.

The effect of group support psychotherapy on adherence to anti-retroviral therapy and viral suppression among HIV positive young people: Study protocol for a pilot randomized controlled trial

Background

Several studies have demonstrated an association between psychological risk factors and HIV disease progression. However, there is limited information on the use of psychological interventions to improve HIV treatment outcomes in young people living with HIV.

Objective

This pilot trial aims to evaluate the feasibility, acceptability and preliminary effectiveness of group support psychotherapy in improving adherence to anti-retroviral therapy and viral suppression in young people living with HIV in Uganda.

Methods

We recruited 120 young people with HIV, aged 10–18 years, who had non-viral suppression 6 months after initiating first-line anti-retroviral therapy (ART) from community based HIV clinics in Kitgum district, northern Uganda. Participants were randomly assigned to receive GSP plus IAC (N = 60) or IAC alone (N = 60). Primary outcomes will be indicators of feasibility and acceptability as well as preliminary effectiveness of GSP in improving ART adherence and viral suppression analysed by intention to treat using cluster-adjusted t tests and permutation tests. Secondary outcomes will be measures of depression, anxiety and cost-effectiveness.

Results

The trial has been approved by the Makerere College of Health Sciences School of Health Sciences Research Ethics Committee, and the Uganda National Council of Science and Technology. Recruitment began in June 2021 and 120 young people living with HIV with their adult caregivers have been recruited to the trial. An analysis of baseline and 6-month data is in progress. The results of this trial will not only be presented at national and international conferences but also submitted for publication in peer-reviewed journals and as a report to the funding agencies.

Conclusions

This pilot trial will provide critical evidence to support the ongoing mental health integration into routine HIV care in Uganda.

Challenges and Fears of Adolescents and Young Adults Living with HIV Facing Transition to Adult HIV Care

Adolescents and young adults living with perinatally-acquired HIV (AYLPHIV) have poor outcomes along each step of the HIV care continuum due to challenges in seeking care and advocating for themselves. The transition from paediatric to adult HIV care is a particularly high-risk period for AYLPHIV in rural Uganda. We conducted in-depth interviews with AYLPHIV (n = 30), caregivers (n = 10), and healthcare providers (n = 10) to understand challenges facing AYLPHIV during the transition from paediatric to adult HIV care. Themes were identified by thematic content analysis. Transition-related challenges and fears included difficulty navigating the adult HIV clinic; loss of informational support; long wait times at the adult HIV clinic; lack of privacy, and fear of HIV status disclosure and stigma; and loss of support from caregivers, and health care providers. Before transitioning to adult HIV care, AYLPHIV should be adequately prepared and given appropriate information to help them navigate adult HIV care.

The impact of community-based, peer-led sexual and reproductive health services on knowledge of HIV status among adolescents and young people aged 15 to 24 in Lusaka, Zambia: The Yathu Yathu cluster-randomised trial

BACKGROUND

The growing population of adolescents and young people (AYP) aged 15 to 24 in sub-Saharan Africa face a high burden of HIV in many settings. Unintended pregnancies among adolescent girls in the region remain high. Nonetheless, the sexual and reproductive health (SRH) service needs of AYP have remained underserved. We conducted a cluster-randomised trial (CRT) to estimate the impact of community-based, peer-led SRH service provision on knowledge of HIV status and other SRH outcomes, including met need for contraceptives.

METHODS AND FINDINGS

Yathu Yathu was a cluster-randomised trial (CRT) conducted from 2019 to 2021 in 2 urban communities in Lusaka, Zambia. The communities were divided into 20 zones (approximately 2,350 AYP/zone) that were randomly allocated to the Yathu Yathu intervention or control arm. In each intervention zone, a community-based hub, staffed by peer support workers, was established to provide SRH services. In 2019, a census was conducted in all zones; all consenting AYP aged 15 to 24 were given a Yathu Yathu card, which allowed them to accrue points for accessing SRH services at the hub and health facility (intervention arm) or the health facility only (control arm). Points could be exchanged for rewards, thus acting as an incentive to use SRH services in both arms. We conducted a cross-sectional survey in 2021 to estimate the impact of Yathu Yathu on the primary outcome: knowledge of HIV status (self-reporting living with HIV or HIV testing in the last 12 months) and secondary outcomes, including use of pre-exposure prophylaxis (PrEP) in the last 12 months, current use of antiretroviral therapy (ART), and met need for contraceptive services. The sampling was stratified on sex and age group, and we analysed data at cluster-level using a two-stage process recommended for CRTs with <15 clusters/arm. A total of 1,989 AYP consented to participate in the survey (50% male); consent was similar across arms (63% consent/arm). Across zones, knowledge of HIV status ranged from 63.6% to 81.2% in intervention zones and 35.4% to 63.0% in control zones. Adjusting for age, sex, and community, knowledge of HIV status was higher in the intervention arm compared to control (73.3% versus 48.4%, respectively, adjusted prevalence ratio (PR) 1.53 95% CI 1.36, 1.72; p < 0.001). By age and sex, results were similar. There was no evidence for impact on any secondary outcomes, including current use of ART and met need for contraceptives. There were no adverse events reported in either arm. A key limitation of our trial is that approximately 35% of the AYP randomly selected for participation in the endline survey could not be reached.

CONCLUSIONS

Delivering community-based, peer-led SRH services increased knowledge of HIV status among AYP, both males and females, compared with the control arm. Scaling up the highly effective Yathu Yathu strategy has the potential to make a substantial contribution to increasing access to HIV prevention and care services for young people. However, additional implementation research is needed to understand how to improve uptake of broader SRH services, beyond uptake of HIV testing.

Long-Term Post-Transition Outcomes of Adolescents and Young Adults Living With Perinatally and Non-perinatally Acquired HIV in Southeast Asia

PURPOSE

We assessed factors associated with clinical, social, and behavioral outcomes of adolescents and young adults with HIV (AYHIV) in Southeast Asia after transition from pediatric to adult HIV care.

METHODS

AYHIV in Malaysia, Thailand, and Vietnam were prospectively followed through annual clinical assessments and laboratory testing. Data were described descriptively and a generalized estimating equation was used to calculate independent predictors for HIV viremia (>40 copies/mL).

RESULTS

A total of 93 AYHIV were followed until February 2019: 60% female, 94% acquired HIV perinatally, 81% Thai, median age 20 (interquartile range, 18-21) years. The median follow-up time was 94 (91-100) weeks; 88% completed the study. At week 96, median CD4 was 557 cells/mm³ (interquartile range, 337-786), 77% had suppressed HIV viral load, 39% reported recent alcohol use, 49% had been sexually active, 53% of females and 36% of males intended to have children, and 23% screened positive for moderate depression (Patient Health Questionnaire-9 score ≥9) or reported suicidal ideation. HIV viremia was associated with <90% adherence to HIV treatment (adjusted incidence rate ratio [aIRR] 2.2 [1.28-3.78]), CD4 count ≤500 cells/mm³ (aIRR 4.75 [2.11-10.69]), and being on a nonnucleoside reverse transcriptase inhibitor regimen (vs. protease inhibitor aIRR 2.71 [1.13-6.49]). Having a trusted person to talk with about their feelings was protective (vs. never; usually or always, aIRR 0.41 [0.18-0.92]).

DISCUSSION

After transition to adult HIV care, there were indications of social isolation and mental health problems that could prevent these AYHIV from maintaining control over their HIV infection and hinder progress toward social independence.

Reduced probability of improving viro-immunological state in subjects with vertical transmission of HIV reaching adult age: A multicenter retrospective cohort study

INTRODUCTION

Young adults with vertical transmission (VT) of human immunodeficiency virus (HIV) represent a fragile population. This study evaluates factors associated with viro-immunological outcome of these patients.

METHODS

We performed a multicenter study including HIV-infected subjects with VT ≥ 18 years old from six Italian clinics. Subjects were observed from birth to death, lost to follow-up, or last visit until December 31, 2019. Condition of "optimal viro-immunological status" (OS) was defined as the simultaneous presence of HIV ribonucleic acid (RNA) < 50 copies/mL, CD4+ > 500 cells/mm³ , and CD4+/CD8+ ratio ≥ 1.

RESULTS

A total of 126 subjects were enrolled. At 18 years of age, 52/126 (44.4%) had HIV-RNA > 50 copies/mL, 47/126 (38.2%) had CD4+ < 500/mm³ , and 78/126 (67.2%) had CD4+/CD8+ < 1; 28 subjects (23.7%) presented in the condition of OS. Having a CD4+/CD8+ ratio ≥ 1 at 18 years of age was related with an increased probability of shift from suboptimal viro-immunological status (SOS) to OS (HR: 7.7, 95% confidence interval [CI]: 4.23-14.04), and a reduced risk of shift from the OS to the SOS (HR: 0.49, 95% CI: 0.26-0.92). Acquired immunodeficiency syndrome (AIDS) diagnosis significantly reduced the probability of shift from a viro-immunological SOS to OS (HR: 0.09, 95% CI: 0.03-0.30). Subjects who had not achieved an OS at 18 years of age had an increased risk of discontinuation of combination antiretroviral therapy (cART, p = .019).

CONCLUSIONS

Only a small proportion of subjects with VT of HIV reached the adult age with "OS". Transition to the adult care with a compromised viro-immunological condition represents a negative driver for future optimal infection control, with a higher risk of discontinuation of cART and a reduced probability to improve the immunological status later in the years.

Transition Interventions for Adolescents on Antiretroviral Therapy on Transfer from Pediatric to Adult Healthcare: A Systematic Review

Globally, adolescents living with HIV (ALHIV) experience poor health outcomes such as low retention in care, ART non-adherence and viral non-suppression. These outcomes coincide with the period during and after their transition from pediatric to adult healthcare. This study aimed to systematically describe the compendium of transition interventions and synthesize the effects of such transition interventions on adherence to ART, retention in care and viral load suppression. Seven databases and Google Scholar were searched and the review findings were reported according to the Preferred Reporting Items Stipulated for Systematic Reviews and Meta-Analyses. The risk of bias and the strength of evidence were assessed using the National Institutes of Health quality assessment tool for observational cohort and cross-sectional studies. Seven studies (two cross-sectional, two retrospective cohort and three prospective cohort studies), with sample sizes ranging from 13 to 192, were included in the narrative synthesis. There was high-quality evidence that these interventions-Individualized care plans, communication, psychological support, and health and sexual education and mHealth-improved adherence, retention in care and viral load suppression at post-transition over the short and long term. In contrast, group transition intervention produced weak quality evidence. Hence, transition interventions including a combination of the high-quality evidenced interventions mentioned above can improve treatment outcomes for adolescents on ART.

"It's about making adolescents in charge of their health": policy-makers' perspectives on optimizing the health care transition among adolescents living with HIV in Kenya

ABSTRACTThe health care transition (HCT) from pediatric to adult care is a potential contributor to poor clinical outcomes among adolescents living with HIV (ALHIV). In sub-Saharan Africa (SSA), there is limited information on effective tools and processes to prepare and support ALHIV through this transition. This study elicited perspectives of policy-makers regarding barriers and facilitators to successful HCT among ALHIV in Kenya. Twenty in-depth interviews (IDIs) were conducted with policy-makers using a semi-structured guide. Using the socio-ecological model (SEM) as an organizing framework, directed content and thematic network analyses methods were used to characterize themes related to key influences on HCT processes and to describe actionable recommendations for improved tools and resources. Policy-makers identified multilevel support, including the development of a triadic relationship between the caregiver, healthcare worker (HCW) and adolescent, as an essential strategy for improved HCT success. Across the SEM, policy-makers described the importance of actively engaging adolescents in their care to promote increased ownership and autonomy over health decisions. At the structural level, the need for more comprehensive HCT guidelines and improved HCW training was highlighted. Expanded HCT tools and guidelines, that emphasize supportive relationships and intensified adolescent engagement, may improve HCT processes and outcomes.

Adherence challenges and opportunities for optimizing care through enhanced adherence counseling for adolescents with suspected HIV treatment failure in Kenya

Background

Adolescents living with HIV (ALHIV) experience higher mortality and are more likely to have poor antiretroviral therapy (ART) adherence and unsuppressed viral load (VL) compared to adults. Enhanced adherence counseling (EAC) is a client-centered counseling strategy that aims to identify and address barriers to optimal ART use and can be tailored to the unique needs of adolescents. This study aimed to better understand adherence barriers among ALHIV with suspected treatment failure and their experience with EAC to inform future programming.

Methods

A qualitative study was conducted in Homa Bay and Turkana counties, Kenya in 2019 with adolescents and caregivers of children and adolescents living with HIV with suspected treatment failure after ≥6 months on ART and who had received ≥1 EAC sessions. Sixteen focus group discussions (FGDs) were conducted; five FGDs each were held with adolescents 12–14 years (n = 48) and 15–19 years (n = 36). Caregivers (n = 52) participated in six FGDs. Additionally, 17 healthcare workers providing pediatric/adolescent HIV services participated in in-depth interviews. Audio recordings were transcribed and translated from Kiswahili or Dholuo into English and coded using MAXQDA software. Data were thematically analyzed by participant group.

Results

Participants identified adolescents’ fear of being stigmatized due to their HIV status and their relationship with and level of support provided by caregivers. This underpinned and often undermined adolescents’ ART-taking behavior and progress towards more independent medication management. Adolescents were generally satisfied with EAC and perceived it to be important in improving adherence and reducing VL. However, problems were noted with facility-based, individual EAC counseling, including judgmental attitudes of providers and difficulties traveling to and keeping EAC clinic appointments. Participant-suggested improvements to EAC included peer support groups in addition to individual counseling, allowing for greater flexibility in the timing and location of sessions and greater caregiver involvement.

Conclusions

The findings provide opportunities to better tailor EAC interventions to promote improved ALHIV adherence and caregiver-supported disease management. Multi-prong EAC interventions that include peer-led and community approaches and target adolescent and caregiver treatment literacy may improve EAC delivery, address issues contributing to poor adherence, and position adolescents to achieve viral suppression.

Community-based accompaniment for adolescents transitioning to adult HIV care in urban Peru: a pilot study

We piloted a community-based intervention to improve outcomes among adolescents living with HIV who were transitioning to adult-oriented care in Lima, Peru. We assessed feasibility and potential effectiveness, including within-person changes in self-reported adherence, psychosocial metrics (NIH Toolbox), and transition readiness (“Am I on TRAC” questionnaire, “Got Transition” checklist). From October 2019 to January 2020, we enrolled 30 adolescents (15–21 years). The nine-month intervention consisted of logistical, adherence and social support delivered by entry-level health workers and group sessions to improve health-related knowledge and skills and social support. In transition readiness, we observed within-person improvements relative to baseline. We also observed strong evidence of improvements in adherence, social support, self-efficacy, and stress, which were generally sustained three months post-intervention. All participants remained in treatment after 12 months. The intervention was feasible and potentially effective for bridging the transition to adult HIV care. A large-scale evaluation, including biological endpoints, is warranted.

"I was still very young": agency, stigma and HIV care strategies at school, baseline results of a qualitative study among youth in rural Kenya and Uganda

INTRODUCTION

Adolescents and young adults living with HIV (AYAH) have the lowest rates of retention in HIV care and antiretroviral therapy (ART) adherence, partly due to the demands of school associated with this life stage, to HIV-related stigma and to fears of serostatus disclosure. We explore the implications of school-based stigma and disclosure on the development of agency during a critical life stage in rural Kenya and Uganda.

METHODS

We conducted a qualitative study in the baseline year of the SEARCH Youth study, a combination intervention using a life-stage approach among youth (15-24 years old) living with HIV in western Kenya and southwestern Uganda to improve viral load suppression and health outcomes. We conducted in-depth, semi-structured interviews in 2019 with three cohorts of purposively selected study participants (youth [n = 83], balanced for sex, life stage and HIV care status; recommended family members of youth [n = 33]; and providers [n = 20]). Inductive analysis exploring contextual factors affecting HIV care engagement revealed the high salience of schooling environments.

RESULTS

Stigma within school settings, elicited by non-consensual serostatus disclosure, medication schedules and clinic appointments, exerts a constraining factor around which AYAH must navigate to identify and pursue opportunities available to them as young people. HIV status can affect cross-generational support and cohort formation, as AYAH differ from non-AYAH peers because of care-related demands affecting schooling, exams and graduation. However, adolescents demonstrate a capacity to overcome anticipated stigma and protect themselves by selectively disclosing HIV status to trusted peers and caregivers, as they develop a sense of agency concomitant with this life stage. Older adolescents showed greater ability to seek out supportive relationships than younger ones who relied on adult caregivers to facilitate this support.

CONCLUSIONS

School is a potential site of HIV stigma and also a setting for learning how to resist such stigma. School-going adolescents should be supported to identify helpful peers and selectively disclose serostatus as they master decision making about when and where to take medications, and who should know. Stigma is avoided by fewer visits to the clinic; providers should consider longer refills, discreet packaging and long-acting, injectable ART for students.

Attrition and associated factors among children living with HIV at a tertiary hospital in Eritrea: a retrospective cohort analysis

BACKGROUND

Reducing attrition in paediatric HIV-positive patients using combined antiretroviral therapy (cART) programmes in sub-Saharan Africa is a challenge. This study explored the rates and predictors of attrition in children started on cART in Asmara, Eritrea.

METHODS

This was a retrospective cohort study using data from all paediatric patients on cART between 2005 and 2020, conducted at the Orotta National Referral and Teaching Hospital. Kaplan-Meier estimates of the likelihood of attrition and multivariate Cox proportional hazards models were used to assess the factors associated with attrition. All p values were two sided and p<0.05 was considered statistically significant.

RESULTS

The study enrolled 710 participants with 374 boys (52.7%) and 336 girls (47.3%). After 5364 person-years' (PY) follow-up, attrition occurred in 172 (24.2%) patients: 65 (9.2%) died and 107 (15.1%) were lost to follow-up (LTFU). The crude incidence rate of attrition was 3.2 events/100 PY, mortality rate was 2.7/100 PY and LTFU was 1.2/100 PY. The independent predictors of attrition included male sex (adjusted HR (AHR)=1.6, 95% CI: 1 to 2.4), residence outside Zoba Maekel (AHR=1.5, 95% CI: 1 to 2.3), later enrolment years (2010-2015: AHR=3.2, 95% CI: 1.9 to 5.3; >2015: AHR=6.1, 95% CI: 3 to 12.2), WHO body mass index-for-age z-score <-2 (AHR=1.4, 95% CI: 0.9 to 2.1), advanced HIV disease (WHO III or IV) at enrolment (AHR=2.2, 95% CI: 1.2 to 3.9), and initiation of zidovudine+lamivudine or other cART backbones (unadjusted HR (UHR)=2, 95% CI: 1.2 to 3.2). In contrast, a reduced likelihood of attrition was observed in children with a record of cART changes (UHR=0.2, 95% CI: 0.15 to 0.4).

CONCLUSION

A low incidence of attrition was observed in this study. However, the high mortality rate in the first 24 months of treatment and late presentation are concerning. Therefore, data-driven interventions for improving programme quality and outcomes should be prioritised.

Perspectives About Transition Readiness Among Adolescents and Young People Living With Perinatally Acquired HIV in Rural, Southwestern Uganda: A Qualitative Study

ABSTRACT

Despite the availability of antiretroviral therapy, treatment outcomes are worse among adolescents and young adults living with perinatally acquired HIV (AYLPHIV). These disparities are magnified during the transition from pediatric to adult-based HIV care. We conducted in-depth interviews with AYLPHIV aged 15-24 years ( n = 30), their caregivers ( n = 10), and health care providers ( n = 10). All participants provided written assent and/or informed consent to enroll. Thematic content analysis was used to identify and analyze themes relevant to transition readiness. We grouped perspectives on transition readiness into 4 themes: preparation for transition, communication between stakeholders, social support, and timing of transition. AYLPHIV in sub-Saharan Africa who are facing a transition to adult HIV care should be equipped with relevant information about their illness, self-advocacy skills, and support from caregivers and health care providers to remain engaged in HIV care.

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.

Transitioning from paediatric to HIV adult care services for adolescents and young people living with HIV in the African region: a scoping review protocol

INTRODUCTION

The number of children living with HIV is increasing worldwide and is a major public health concern as they grow into adolescence and young adulthood with increasing access to antiretroviral therapy (ART) especially in the African region. There is a pressing need to transfer them from paediatric to adult care which has implications for their well-being. The objective of this scoping review is to systematically review published and unpublished literature to understand the extent and type of evidence in relation to the transition of adolescents to adult HIV clinics in the African region.

METHODS AND ANALYSIS

Following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Extension for Scoping Review) guidelines for conducting a scoping review, we will systematically search online bibliographic databases including PubMed, EMBASE, Google Scholar and bibliographies of pertinent articles. This will be supplemented by searches in grey literature databases. Two reviewers will independently review all articles to determine if they meet eligibility criteria. Any conflicts will be resolved after discussion with a third reviewer to ensure accurate and reliable data collection. Both quantitative and qualitative results will be extracted from all included articles and synthesised in a narrative form in response to the review questions.

ETHICS AND DISSEMINATION

The scoping review does not require ethics approval as we will collect and review existing literature and materials. The results will be disseminated through a peer-reviewed publication, conference presentations and stakeholder meetings to support clinicians, health experts and policy makers develop guidelines and evidence-based transition protocols favourable for the populations in the African region to minimise challenges associated with the transition process.

"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.

Estimating Tuberculosis Transmission Risks in a Primary Care Clinic in South Africa: Modeling of Environmental and Clinical Data

BACKGROUND

Congregate settings, such as healthcare clinics, may play an essential role in Mycobacterium tuberculosis (Mtb) transmission. Using patient and environmental data, we studied transmission at a primary care clinic in South Africa.

METHODS

We collected patient movements, cough frequency, and clinical data, and measured indoor carbon dioxide (CO2) levels, relative humidity, and Mtb genomes in the air. We used negative binomial regression model to investigate associations.

RESULTS

We analyzed 978 unique patients who contributed 14 795 data points. The median patient age was 33 (interquartile range [IQR], 26-41) years, and 757 (77.4%) were female. Overall, median CO2 levels were 564 (IQR 495-646) parts per million and were highest in the morning. Median number of coughs per day was 466 (IQR, 368-503), and overall median Mtb DNA copies/μL/day was 4.2 (IQR, 1.2-9.5). We found an increased presence of Mtb DNA in the air of 32% (95% credible interval, 7%-63%) per 100 additional young adults (aged 15-29 years) and 1% (0-2%) more Mtb DNA per 10% increase of relative humidity. Estimated cumulative transmission risks for patients attending the clinic monthly for at least 1 hour range between 9% and 29%.

CONCLUSIONS

We identified young adults and relative humidity as potentially important factors for transmission risks in healthcare clinics. Our approach should be used to detect transmission and evaluate infection control interventions.

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.

Clinical outcomes among adolescents living with HIV in Kenya following initiation on antiretroviral treatment

In Kenya, HIV/AIDS remains a leading cause of morbidity and mortality among adolescents living with HIV (ALHIV). Our study evaluated associations between demographic and healthcare factors and HIV treatment outcomes among ALHIV in care in Kenya. This retrospective cohort study evaluated the clinical outcomes of newly diagnosed ALHIV enrolled in HIV care during January 2017-June 2018 at 32 healthcare facilities in Homabay and Kakamega Counties. Demographic and clinical data were abstracted from patient clinical records and registers during the follow up study period January 2017-through May 2019. ALHIV were stratified by age (10-14 versus 15-19 years). Categorical variables were summarized using descriptive statistics; continuous variables were analyzed using mean values. The latest available treatment and virological outcomes for ALHIV were assessed. 330 ALHIV were included in the study (mean age 15.9 years; 81.8% female, 63.0% receiving HIV care at lower-level healthcare facilities). Most (93.2%) were initiated on ART within 14 days of diagnosis; 91.4% initiated EFV-based regimens. Of those on ART, only 44.6% were active on care at the end of the study period. Of those eligible for viral load testing, 83.9% were tested with 84.4% viral suppression rate. Retention in care was higher at higher-level facilities (67.5%) compared to lower-level facilities (28.6%). Factors associated with higher retention in care were school attendance (aRR = 1.453), receipt of disclosure support (aRR = 13.315), and receiving care at a high-level health facility (aRR = 0.751). Factors associated with viral suppression included older age (15-19 years) (aRR = 1.249) and pre-ART clinical WHO stage I/II (RR = .668). Viral suppression was higher among older ALHIV. Studies are needed to evaluate effective interventions to improve outcomes among ALHIV in Kenya.

"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.

24-Month Clinical, Immuno-Virological Outcomes, and HIV Status Disclosure in Adolescents Living With Perinatally-Acquired HIV in the IeDEA-COHADO Cohort in Togo and Côte d'Ivoire, 2015-2017

Background: Adolescents living with perinatally-acquired HIV (APHIV) face challenges including HIV serostatus disclosure. We assessed their 24-month outcomes in relation to the disclosure of their own HIV serostatus. Methods: Nested within the International epidemiologic Database to Evaluate AIDS pediatric West African prospective cohort (IeDEA pWADA), the COHADO cohort included antiretroviral (ART)-treated APHIV aged 10-19 years, enrolled in HIV care before the age of 10 years, in Abidjan (Côte d'Ivoire) and Lomé (Togo) in 2015. We measured the HIV serostatus disclosure at baseline and after 24 months and analyzed its association with a favorable combined 24-month outcome using logistic regression. The 24-month combined clinical immuno-virological outcome was defined as unfavorable when either death, loss to follow-up, progression to WHO-AIDS stage, a decrease of CD4 count >10% compared to baseline, or a detectable viral load (VL > 50 copies/mL) occurred at 24 months. Results: Overall, 209 APHIV were included (51.6% = Abidjan, 54.5% = females). At inclusion, the median CD4 cell count was 521/mm 3 [IQR (281-757)]; 29.6% had a VL measurement, of whom, 3.2% were virologically suppressed. APHIV were younger in Lomé {median age: 12 years [interquartile range (IQR): 11-15]} compared to Abidjan [14 years (IQR: 12-15, p = 0.01)]. Full HIV-disclosure increased from 41.6% at inclusion to 74.1% after 24 months. After 24 months of follow-up, six (2.9%) died, eight (3.8%) were lost to follow-up, and four (1.9%) were transferred out. Overall, 73.7% did not progress to the WHO-AIDS stage, and 62.7% had a CD4 count above (±10%) of the baseline value (48.6% in Abidjan vs. 69.0% in Lomé, p < 0.001). Among the 83.7% with VL measurement, 48.8% were virologically suppressed (Abidjan: 45.4%, Lomé: 52.5%, p <0.01). The 24-month combined outcome was favorable for 45% (29.6% in Abidjan and 61.4% in Lomé, p < 0.01). Adjusted for baseline variables, the 24-month outcome was worse in Lomé in those who had been disclosed for >2 years compared to those who had not been disclosed to [aOR = 0.21, 95% CI (0.05-0.84), p = 0.03]. Conclusions: The frequency of HIV-disclosure improved over time and differed across countries but remained low among West African APHIV. Overall, the 24-month outcomes were poor. Disclosure before the study was a marker of a poor 24-month outcome in Lomé. Context-specific responses are urgently needed to improve adolescent care and reach the UNAIDS 90% target of virological success.

Transition to adult care: Exploring factors associated with transition readiness among adolescents and young people in adolescent ART clinics in Uganda

Background

Transition readiness refers to a client who knows about his/her illness and oriented towards future goals and hopes, shows skills needed to negotiate healthcare, and can assume responsibility for his/ her treatment, and participate in decision-making that ensures uninterrupted care during and after the care transition to adult HIV care. There is a paucity of research on effective transition strategies. This study explored factors associated with adolescent readiness for the transition into adult care in Uganda.

Methods

A cross-sectional study was conducted among 786 adolescents, and young people living with HIV randomly selected from 9 antiretroviral therapy clinics, utilizing a structured questionnaire. The readiness level was determined using a pre-existing scale from the Ministry of Health, and adolescents were categorized as ready or not ready for the transition. Bivariate and multivariate analyses were conducted.

Results

A total of 786 adolescents were included in this study. The mean age of participants was 17.48 years (SD = 4). The majority of the participants, 484 (61.6%), were females. Most of the participants, 363 (46.2%), had no education. The majority of the participants, 549 (69.8%), were on first-line treatment. Multivariate logistic regression analysis found that readiness to transition into adult care remained significantly associated with having acquired a tertiary education (AOR 4.535, 95% CI 1.243–16.546, P = 0.022), trusting peer educators for HIV treatment (AOR 16.222, 95% CI 1.835–143.412, P = 0.012), having received counselling on transition to adult services (AOR 2.349, 95% CI 1.004–5.495, P = 0.049), having visited an adult clinic to prepare for transition (AOR 6.616, 95% CI 2.435–17.987, P = < 0.001) and being satisfied with the transition process in general (AOR 0.213, 95% CI 0.069–0.658, P = 0.007).

Conclusion

The perceived readiness to transition care among young adults was low. A series of individual, social and health system and services factors may determine successful transition readiness among adolescents in Uganda. Transition readiness may be enhanced by strengthening the implementation of age-appropriate and individualized case management transition at all sites while creating supportive family, peer, and healthcare environments.

Brief Report: Time to Repeat Viral Load Testing Among Unsuppressed Adolescents and Young Adults Living With HIV in Kenya

BACKGROUND

Repeat HIV viral load (VL) testing is required after unsuppressed VL to confirm treatment failure. We assessed proportion of adolescents and young adults living with HIV (AYALHIV) in Kenya with a confirmatory VL test and time to repeat testing.

DESIGN

A retrospective analysis of longitudinal data abstracted from Kenya's national VL database.

METHODS

VL data for AYALHIV who were 10-24 year old between April 2017 and May 2019 were abstracted from 117 HIV care clinics. Records were eligible if at least one VL test was performed ≥6 months after antiretroviral therapy (ART) initiation. The proportion of unsuppressed AYALHIV (≥1000 copies/mL) and time in months between first unsuppressed VL and repeat VL was determined.

RESULTS

We abstracted 40,928 VL records for 23,969 AYALHIV; of whom, 17,092 (71%) were eligible for this analysis. Of these, 12,122 (71%) were women, median age of 19 years [interquartile range (IQR): 13-23], and median ART duration of 38 months (IQR: 16-76). Among eligible AYALHIV, 4010 (23%) had an unsuppressed VL at first eligible measurement. Only 316 (8%) of the unsuppressed AYALHIV had a repeat VL within 3 months and 1176 (29%) within 6 months. Among 2311 virally unsuppressed AYALHIV with a repeat VL, the median time between the first and the repeat VL was 6 months (IQR: 4-8), with 1330 (58%) having confirmed treatment failure.

CONCLUSIONS

One-quarter of AYALHIV on ART had unsuppressed VL, with less than a third receiving a repeat VL within 6 months. Strategies to improve VL testing practices are needed to improve AYALHIV's outcomes.

Adolescents and young adults with early acquired HIV infection in the united states: unique challenges in treatment and secondary prevention

INTRODUCTION

Worldwide, children who acquired human immunodeficiency virus (HIV) at an early age, either perinatally or through blood transfusion, are reaching adolescence and adulthood due to successful antiretroviral treatment (ART). While many are thriving, a significant proportion face unprecedented multilevel challenges that can affect their long-term outcomes. Specifically, longstanding and poorly controlled HIV resulting from inadequate early regimens and nonadherence, along with the toxicities of some ART agents, can predispose them to sequelae including HIV-associated complications and other comorbidities.

AREAS COVERED

This paper reviews and summarizes the unique issues facing adolescents and young adults with early acquired HIV (AYA-EAHIV), including ART challenges, emerging comorbidities, and complications, including mental health comorbidities, secondary prevention, and transition from pediatric/adolescent to adult care.

EXPERT OPINION

AYA-EAHIV are a special population that have lived their entire lives with the physical and psychological toll of HIV mandating targeted and purposeful approaches to optimize their management and outcomes. Multifaceted inclusive and context-specific approaches focusing on heightened research, risk reduction interventions, and 'outside the box' thinking will be required to optimize treatment and reduce morbidity and mortality.

Ethical challenges of the healthcare transition to adult antiretroviral therapy (ART) clinics for adolescents and young people with HIV in Uganda

Background

Whereas many adolescents and young people with HIV require the transfer of care from paediatric/adolescent clinics to adult ART clinics, this transition is beset with a multitude of factors that have the potential to hinder or facilitate the process, thereby raising ethical challenges of the transition process. Decisions made regarding therapy, such as when and how to transition to adult HIV care, should consider ethical benefits and risks. Understanding and addressing ethical challenges in the healthcare transition could ensure a smooth and successful transition. The purpose of this study was to analyze the ethical challenges of transitioning HIV care for adolescents into adult HIV clinics.

Methods

Data presented were derived from 191 adolescents attending nine different health facilities in Uganda, who constituted 18 focus group discussions. In the discussions, facilitators and barriers regarding adolescents transitioning to adult HIV clinics were explored. Guided by the Silences Framework for data interpretation, thematic data analysis was used to analyze the data. The principles of bioethics and the four-boxes ethics framework for clinical care (patient autonomy, medical indications, the context of care, and quality of life) were used to analyze the ethical issues surrounding the transition from adolescent to adult HIV care.

Results

The key emerging ethical issues were: reduced patient autonomy; increased risk of harm from stigma and loss of privacy and confidentiality; unfriendly adult clinics induce disengagement and disruption of the care continuum; patient preference to transition as a cohort, and contextual factors are critical to a successful transition.

Conclusion

The priority outcomes of the healthcare transition for adolescents should address ethical challenges of the healthcare transition such as loss of autonomy, stigma, loss of privacy, and discontinuity of care to ensure retention in HIV care, facilitate long-term self-care, offer ongoing all-inclusive healthcare, promote adolescent health and wellbeing and foster trust in the healthcare system. Identifying and addressing the ethical issues related to what hinders or facilitates successful transitions with targeted interventions for the transition process may ensure adolescents and young people with HIV infection remain healthy across the healthcare transition.

Clinic-level and individual-level factors that influence HIV viral suppression in adolescents and young adults: a national survey in Kenya

OBJECTIVES

To determine clinic-level and individual-level correlates of viral suppression among HIV-positive adolescents and young adult (AYA) aged 10-24 years receiving antiretroviral treatment (ART).

DESIGN

Multilevel cross-sectional analysis using viral load data and facility surveys from HIV treatment programs throughout Kenya.

METHODS

We abstracted medical records of AYA in HIV care, analyzed the subset on ART for more than 6 months between January 2016 and December 2017, and collected information on services at each clinic. Multilevel logistic regression models were used to determine correlates of viral suppression at most recent assessment.

RESULTS

In 99 HIV clinics, among 10 096 AYA on ART more than 6 months, 2683 (27%) had unsuppressed viral load at last test. Among 16% of clinics, more than 80% of AYA were virally suppressed. Clinic-level correlates of individual viral suppression included designated adolescent spaces [aOR: 1.32, 95% CI (1.07-1.63)] and faster viral load turnaround time [aOR: 1.06 (95% CI 1.03-1.09)]. Adjusting for clinic-level factors, AYA aged 10-14 and 15-19 years had lower odds of viral suppression compared with AYA aged 20-24 years [aOR: 0.61 (0.54-0.69) and 0.59 (0.52-0.67], respectively. Compared with female patients, male patients had lower odds of viral suppression [aOR: 0.69 (0.62-0.77)]. Compared with ART duration of 6-12 months, ART for 2-5, above 5-10 or more than 10 years was associated with poor viral suppression (P < 0.001).

CONCLUSION

Dedicated adolescent space, rapid viral load turnaround time, and tailored approaches for male individuals and perinatally infected AYA may improve viral suppression. Routine summarization of viral load suppression in clinics could provide benchmarking to motivate innovations in clinic-AYA and individual-AYA care strategies.

"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.

Disclosure, Social Support, and Mental Health are Modifiable Factors Affecting Engagement in Care of Perinatally-HIV Infected Adolescents: A Qualitative Dyadic Analysis

Adolescents living with perinatally acquired HIV in South Africa face significant barriers to successful transition from pediatric to adult care. We performed in-depth qualitative interviews with 41 adolescents living with HIV and 18 of their caregivers to investigate modifiable factors to improve engagement in care prior to transition to adult care. Based on dyadic, inductive content analysis, findings suggest that HIV status disclosure, social support, and mental health are targets for improvement in engagement in care. Early disclosure and a sense of belonging facilitated engagement in care, while barriers included delayed or inadequate disclosure, denial, and lack of disclosure to others. Adherence support improved by having a biological mother as a direct supervisor. Barriers to care included changing caregivers, abandonment, undiagnosed mental health problems and learning difficulties. Despite these factors, the majority of adolescents showed resilience and remained engaged in care despite difficult circumstances.

Adolescent transition to adult care for HIV-infected adolescents in Kenya (ATTACH): study protocol for a hybrid effectiveness-implementation cluster randomised trial

INTRODUCTION

Successfully transitioning adolescents to adult HIV care is critical for optimising outcomes. Disclosure of HIV status, a prerequisite to transition, remains suboptimal in sub-Saharan Africa. Few interventions have addressed both disclosure and transition. An adolescent transition package (ATP) that combines disclosure and transition tools could support transition and improve outcomes.

METHODS AND ANALYSIS

In this hybrid type 1 effectiveness-implementation cluster randomised controlled trial, 10 HIV clinics with an estimated ≥100 adolescents and young adults age 10-24 living with HIV (ALWHIV) in Kenya will be randomised to implement the ATP and compared with 10 clinics receiving standard of care. The ATP includes provider tools to assist disclosure and transition. Healthcare providers at intervention clinics will receive training on ATP use and support to adapt it through continuous quality improvement cycles over the initial 6 months of the study, with continued implementation for 1 year. The primary outcome is transition readiness among ALWHIV ages 15-24 years, assessed 6 monthly using a 22-item readiness score. Secondary outcomes including retention and viral suppression among ALWHIV at the end of the intervention period (month 18), implementation outcomes (acceptability, feasibility, fidelity, coverage and penetration) and programme costs complement effectiveness outcomes. The primary analysis will be intent to treat, using mixed-effects linear regression models to compare transition readiness scores (overall and by domain (HIV literacy, self-management, communication, support)) over time in control and intervention sites with adjustment for multiple testing, accounting for clustering by clinic and repeated assessments. We will estimate the coefficients and 95% CIs with a two- sided α=0.05.

ETHICS AND DISSEMINATION

The study was approved by the University of Washington Institutional Review Board and the Kenyatta National Hospital Ethics and Research Committee. Study results will be shared with participating facilities, county and national policy-makers.

Patterns of detectable viral load in a cohort of HIV-positive adolescents on antiretroviral therapy in South Africa

INTRODUCTION

Despite improved treatment and access to care, adolescent AIDS deaths are decreasing more slowly than in any other age group. There is lack of longitudinal data around adolescent adherence and the dynamics of viraemia over time. We aimed to describe patterns of detectable viral load (VL) in a cohort of adolescents attending an ARV clinic in Cape Town, South Africa.

METHODS

We conducted a retrospective cohort study of all patients on antiretroviral therapy aged 10 to 19 years. Participants were included if they underwent at least two VL measurements and remained in care at the Groote Schuur Hospital HIV Clinic for at least 24 months between 2002 and 2016. The primary outcome was two consecutive HIV VL >100 copies/mL, in line with the lower limit of detection of assays in use over the follow-up period.

RESULTS AND DISCUSSION

Of the 482 screened participants, 327 met inclusion criteria. Most participants had perinatally acquired HIV (n = 314; 96%), and 170 (52%) were males. Overall, there were 203 episodes of confirmed detectable VL involving 159 (49% (95% CI 43% to 54%)) participants during the follow-up period. Six participants had genotyped resistance to protease inhibitors. Four of these never suppressed, while two suppressed on salvage regimens. Total follow-up time was 1723 person years (PY), of which 880 (51%) were contributed by the 159 participants who experienced detectable VL. Overall time with detectable VL was 370 PY. This comprised 22% of total follow-up time, and 42% of the follow-up time contributed by those who experienced detectable VL. The rate of detectable VL was 11.8 (95% CI 10.3 to 13.5) episodes per 100 PY. The risk increased by 24% for each year of increasing age (Relative Risk 1.24 (95% CI 1.17 to 1.31); p < 0.0001). There was no sex difference with respect to duration (p = 0.4), prevalence (p = 0.46) and rate (p = 0.608) of detectable VL.

CONCLUSIONS

Clinicians need to be alert to the high prevalence of detectable VL during adolescence so as to pre-empt it and act swiftly once it is diagnosed. This study helps to highlight the risk of detectable VL that is associated with increase in age as well the high proportion of time that poorly adherent adolescents spend in this state.

Long-Term Outcomes of HIV-Infected Women Receiving Antiretroviral Therapy After Transferring Out of an Integrated Maternal and Child Health Service in South Africa

BACKGROUND

Integrated maternal and child health (MCH) services improve women's postpartum antiretroviral therapy (ART) outcomes during breastfeeding; however, long-term outcomes after transfer to general ART services remain unknown.

METHODS

The MCH-ART trial demonstrated that maternal retention and viral suppression at 12-months postpartum were improved significantly among women randomized to integrated MCH services continued in the antenatal clinic through cessation of breastfeeding (MCH-ART arm) compared with immediate transfer to general ART services postpartum (standard of care). We reviewed electronic health records for all women who participated in the MCH-ART trial to ascertain retention and gaps in care and invited all women for a study visit 36- to 60-months postpartum including viral load testing.

RESULTS

Of 471 women in MCH-ART, 450 (96%) contributed electronic health record data and 353 (75%) completed the study visit (median 44-month postpartum). At this time, outcomes were identical in both trial arms: 67% retained in care (P = 0.994) and 56% with viral loads <50 copies/mL (P = 0.751). Experiencing a gap in care after delivery was delayed in the MCH-ART arm with 17%, 36%, and 45% of women experienced a gap in care by 12-, 24-, and 36-months postpartum compared with 35%, 48%, and 57% in the standard of care arm, respectively.

CONCLUSIONS

The benefits of integrated maternal HIV and child health care did not persist after transfer to general ART services. The transfer of women postpartum to routine adult care is a critical period requiring interventions to support continuity of HIV care.

Barriers and facilitators for transitioning of young people from adolescent clinics to adult ART clinics in Uganda: unintended consequences of successful adolescent ART clinics

Background

There is a growing number of adolescents and young adults living with HIV (YPLHIV) who require the transfer of care from pediatric/ adolescent clinics to adult Antiretroviral therapy (ART) clinics. A successful transition is critical for optimum health outcomes, yet facilities may lack infrastructure, human resources (with appropriate knowledge and skills), and a supportive environment, as only 3% of clinics in Uganda caring for YPLHIV have a process for supporting this critical transition from pediatric to adult care, and, facilitators and barriers of a successful transition are not well documented. The purpose of this study was to explore the facilitators and barriers of transitioning among adolescents from adolescent clinics to adult ART clinics.

Method

Eighteen focus group discussions were held in nine health facilities with 174 adolescents and YPLHIV to assess barriers and facilitators regarding transitioning to adult clinics. The focus group discussions were audio-recorded and transcribed. The Silences Framework using a thematic approach guided the analysis.

Results

The key emerging issues were: Unfriendly adults in adult clinics, Care provided in the adolescent clinics, fear of stigma from health care providers, Congestion and long waiting time, fear to lose friends were barriers to transitioning. Transitioning preparation is key to a successful transition, moving as a cohort facilitates transition, and care in adult clinics offers new opportunities, could facilitate readiness and transition.

Conclusion

YPLHIV expressed fear to transition to adult clinics mainly because of the perceived better care provided in the adolescent clinic, thus constituting a barrier to smooth transition A range of individual, social and health system and services-related factors hindered transitioning. The expectation of transitioning as a group, assurance of similar care as in the adolescent clinic, and guarantees of confidentiality, privacy, and autonomy in decision-making for care was perceived as facilitators. Understanding barriers and facilitators can enable the Ministry of Health to improve the quality of life of YPLHIV through linkage to care, adherence, retention, and viral suppression. There is a need to better planning and preparation for clinical providers and YPLHIV with a focus on age-appropriate and individualized case management transition as well as focus on improving both clinical and psychosocial support throughout the process.

"Because we all have to grow up": supporting adolescents in Uganda to develop core competencies to transition towards managing their HIV more independently

INTRODUCTION

Sustaining optimal adherence is the major challenge facing adolescents living with HIV (ALHIV), particularly in low-resource settings, where "second-line" is often the last accessible treatment option. We explored the knowledge and skills adolescents need in order to maintain improved adherence behaviours, and the specific ways clinicians and caregivers may support young people to do so more independently.

METHODS

We conducted individual, in-depth interviews with 20 ALHIV aged 10 to 18 years in Uganda in 2017 to 2018. All participants had recently commenced second-line treatment as part of a clinical trial. We used thematic qualitative analysis to examine adherence experiences and challenges while on first-line therapy, as well as specific supports necessary to optimise treatment-taking longer-term.

RESULTS

Adherence difficulties are exacerbated by relatively rapid shifts from caregiver-led approaches during childhood, to an expectation of autonomous treatment-taking with onset of adolescence. For many participants this shift compounded their ongoing struggles managing physical side effects and poor treatment literacy. Switching to second-line typically prompted reversion back to supervised adherence, with positive impacts on self-reported adherence in the immediate term. However, this measure is unlikely to be sustainable for caregivers due to significant caregiver burden (as on first line), and provided little opportunity for clinicians to guide and develop young people's capacity to successfully adopt responsibility for their own treatment-taking.

CONCLUSIONS

As ALHIV in sub-Saharan Africa are attributed increasing responsibility for treatment adherence and HIV management, they must be equipped with the core knowledge and skills required for successful, self-directed care. Young people need to be relationally supported to develop necessary "adherence competencies" within the supportive framework of a gradual "transition" period. Clinic conversations during this period should be adolescent-focussed and collaborative, and treatment-taking strategies situated within the context of their lived environments and support networks, to facilitate sustained adherence. The disclosure of adherence difficulties must be encouraged so that issues can be identified and addressed prior to treatment failure.

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.

Longitudinal evaluation of adherence, retention, and transition patterns of adolescents living with HIV in Nigeria

Introduction

Adherence to antiretroviral therapy (ART) and retention in treatment programs are required for successful virologic suppression and treatment outcomes. As the number of adolescents living with HIV continues to increase globally, more information about adherence and retention patterns during and through transition from child- to adult-centered care is needed to ensure provision of a high level of care and inform development of targeted interventions to improve patient outcomes in this vulnerable population. In this analysis, we sought to describe long-term trends in adherence, retention, and virologic suppression in adolescents receiving ART at a pediatric HIV clinic in Nigeria through transition to the adult clinic.

Setting

The Jos University Teaching Hospital, United States President’s Emergency Plan for AIDS Relief (PEPFAR)-funded HIV clinic in Jos, Plateau State, Nigeria.

Methods

We conducted a retrospective observational longitudinal evaluation of data that had been collected during the course of care in a large pediatric ART program in Nigeria. We used descriptive statistics to define our patient population and quantify retention from ART initiation through adolescence and transition to adult-centered care. Logistic regression was used to evaluate predictors of loss to follow-up. We used medication possession ratio (MPR) to quantify adherence for each year a patient was on ART. To evaluate adherence and virologic suppression, we measured the proportion of patients with ≥95% MPR and the proportion with virologic suppression (viral load ≤400 copies/mL) within each age cohort, and used bivariate analyses to examine any association between MPR and VL suppression for all person-years observed.

Results

A total of 476 patients received at least one dose of ART as an adolescent (ages 10–19 years). The proportions of patients lost to follow-up were: 11.9% (71/597) prior to adolescence, 19.1% (31/162) during adolescence, and 13.7% (10/73) during transition to adult-centered care. While over 80% of patients had ≥95% medication adherence in all age groups, their viral load suppression rates through adolescence and post-transition were only 55.6%–64.0%. For patients that successfully transitioned to adult-centered care, we observed 87.7% (50/57) retention at month 12 post-transition, but only 34.6% (9/26) viral load suppression.

Conclusions

Our evaluation found considerable proportions of adolescents lost to follow-up throughout the ART program cascade. We also found discrepancies between the proportions of patients with ≥95% MPR and the proportions with VL suppression, suggesting that true medication adherence in this population may be poor. Significant attention and targeted interventions to improve retention and adherence focused on adolescents are needed in order for global programs to achieve 90-90-90 goals.
