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

Are social protection and food security accelerators for adolescents to achieve the Global AIDS targets?

INTRODUCTION

Without effective, scalable interventions, we will fail to achieve the Global AIDS Targets of zero AIDS-related deaths, zero HIV transmission and zero discrimination. This study examines associations of social protection and food security among adolescents living with HIV (ALHIV), with three Global AIDS Targets aligned outcomes: antiretroviral treatment (ART) adherence and viral suppression, HIV transmission risk behaviour and enacted stigma.

METHODS

We conducted three study visits over 2014-2018 with 1046 ALHIV in South Africa's Eastern Cape province. Standardized surveys provided information on receipt of government-provided cash transfers and past-week food security, alongside self-reported ART adherence, sexual debut and condom use, and enacted HIV-related stigma. Viral load (VL) data was obtained through data extraction from patient files and linkage with National Health Laboratory Service test results (2014-2020). We used a multivariable random-effects regression model to estimate associations between receiving government cash transfers and food security and three outcomes: ART adherence and viral suppression, delayed sexual debut or consistent condom use and no enacted stigma. We tested moderation by sex and age and fitted disaggregated models for each outcome.

RESULTS

Among the 933 ALHIV completing all three study visits, 55% were female, and the mean age was 13.6 years at baseline. Household receipt of a government cash transfer was associated with improvements on all outcomes: ART adherence and viral suppression (aOR 2.03, 95% CI 1.29-3.19), delayed sexual debut or consistent condom use (aOR 1.62, 95% CI 1.16-2.27) and no enacted stigma (aOR 2.33, 95% CI 1.39-3.89). Food security was associated with improvements on all outcomes: ART adherence and viral suppression (aOR 1.73, 95% CI 1.30-2.30), delayed sexual debut or consistent condom use (aOR 1.30, 95% CI 1.03-1.64) and no enacted stigma (aOR 1.91, 95% CI 1.32-2.76). Receiving both cash transfers and food security increased the probability of ART adherence and VL suppression from 36% to 60%; delayed sexual debut or consistent condom use from 67% to 81%; and no enacted stigma from 84% to 96%.

CONCLUSIONS

Government-provided cash transfers and food security, individually and in combination, are associated with improved outcomes for ALHIV aligned with Global AIDS Targets. They may be important, and underutilized, accelerators for achieving these targets.

Viral load non-suppression among adolescents and youth living with HIV in South Africa

Background

Despite the increased initiation and uptake of antiretroviral therapy (ART) in South Africa, some people living with HIV (PLHIV) who are on ART still have non-suppressed viral load (VL).

Objectives

This study aimed to determine the prevalence of VL non-suppression among adolescents and youth (aged 12 years - 24 years) living with HIV and on ART in South Africa, as well as the factors associated with it.

Method

Data from the 2017 South African national HIV prevalence, incidence, behaviour, and communication survey were analysed. The survey used a multistage-stratified cluster sampling design. A backward stepwise multivariable generalised linear model was used to identify factors associated with VL non-suppression.

Results

The study included 340 participants aged 12 years - 24 years, with a median age of 21 (interquartile range [IQR]: 18-23). The proportion of adolescents and youth living with HIV and on ART with non-suppressed VL was 19.2% (95% confidence interval [CI]: 14.4-25.3). Approximately 60% of the participants were not on ART. The odds of VL non-suppression were significantly higher among youth aged 15 years - 19 years (adjusted odds ratio [AOR] = 1.63 [95% CI: 1.24-2.13], p = 0.001) and aged 20 years - 24 years (AOR = 1.22 [95% CI: 1.06-1.41], p = 0.005) compared to adolescents aged 12 years - 14 years. The odds were significantly lower among individuals of other races (AOR = 0.80 [95% CI: 0.69-0.92], p = 0.003) compared to black African people.

Conclusion

Findings suggest a need for ART education and counselling as part of treatment support. In addition, the promotion of HIV awareness as part of strengthening the HIV treatment and prevention cascade.

Contribution

The article showed the prevalence of VL non-suppression and associated factors among adolescents and youth.

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

BACKGROUND

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

SETTING

Eastern Cape province, South Africa.

METHODS

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

RESULTS

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

CONCLUSIONS

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

Healthcare provisions associated with multiple HIV-related outcomes among adolescent girls and young women living with HIV in South Africa: a cross-sectional study

INTRODUCTION

Adolescent girls and young women (AGYW) living with HIV experience poor HIV outcomes and high rates of unintended pregnancy. Little is known about which healthcare provisions can optimize their HIV-related outcomes, particularly among AGYW mothers.

METHODS

Eligible 12- to 24-year-old AGYW living with HIV from 61 health facilities in a South African district completed a survey in 2018-2019 (90% recruited). Analysing surveys and medical records from n = 774 participants, we investigated associations of multiple HIV-related outcomes (past-week adherence, consistent clinic attendance, uninterrupted treatment, no tuberculosis [TB] and viral suppression) with seven healthcare provisions: no antiretroviral therapy (ART) stockouts, kind and respectful providers, support groups, short travel time, short waiting time, confidentiality, and safe and affordable facilities. Further, we compared HIV-related outcomes and healthcare provisions between mothers (n = 336) and nulliparous participants (n = 438). Analyses used multivariable regression models, accounting for multiple outcomes.

RESULTS

HIV-related outcomes were poor, especially among mothers. In multivariable analyses, two healthcare provisions were "accelerators," associated with multiple improved outcomes, with similar results among mothers. Safe and affordable facilities, and kind and respectful staff were associated with higher predicted probabilities of HIV-related outcomes (p<0.001): past-week adherence (62% when neither accelerator was reported to 87% with both accelerators reported), clinic attendance (71%-89%), uninterrupted ART treatment (57%-85%), no TB symptoms (49%-70%) and viral suppression (60%-77%).

CONCLUSIONS

Accessible and adolescent-responsive healthcare is critical to improving HIV-related outcomes, reducing morbidity, mortality and onward HIV transmission among AGYW. Combining these provisions can maximize benefits, especially for AGYW mothers.

Qualitative Study on the Voices of Adolescents Living with Perinatally Acquired HIV in Selected Clinics in the Limpopo Province of South Africa

The disclosure of HIV status among adolescents living with perinatally acquired HIV (APHIV) has become one of the core challenges in the management of APHIV. Disclosure is a challenge that undermines positive advances and achievements in HIV management. There is limited literature on the voices of APHIV on disclosure of their status. This study aims to explore the current disclosure process and how it affects APHIV. A qualitative exploratory design was employed to conduct one-on-one in-depth interviews using a semi-structured interview guide. Purposive sampling was used to sample 21 APHIV in 16 selected health facilities in the Vhembe district of Limpopo Province, South Africa. Data were analyzed using Tesch's qualitative data method. The findings of this study reflect the gaps in the current disclosure process and guidelines while acknowledging the importance of disclosure to APHIV. A notable finding in this study is that most APHIV, especially those in early adolescence, did not want to know their HIV status due to the stigma attached to an HIV-positive diagnosis. This study suggests that proper training and support of parents and/or guardians in the disclosure process are needed, as they are the primary caregivers of APHIV. The disclosure of HIV status must be a comprehensive part of the management and care of HIV for APHIV. Furthermore, dedicated support programs should be developed and implemented to improve their lives post-disclosure.

Transfusion transmissible infections among blood donors in Ghana: A 3-year multicentered health facility-based retrospective study

Transfusion transmissible infections (TTIs) remain a major health challenge particularly in developing countries. Here, we present a multicentered hospital-based retrospective study on the prevalence, distribution, and risk factors of TTIs in Ghana. Data on blood donors from four health facilities, namely Nkwanta South Municipal Hospital (Oti region), Weija-Gbawe Municipal Hospital (Greater Accra region), SDA Hospital (Northern region) and Wa Municipal Hospital (Upper West region) were extracted and analyzed. Descriptive statistics and multinomial logistic regression were applied to compare sociodemographic data with TTI status. A total of 6094 blood donors were included in this study, and 2% were females. The overall prevalence of TTIs was 21.0% (1232/5868). Specifically, the prevalence of HBV, HCV, HIV, and Syphilis was 6.6% (385/5868), 4.9% (286/5830), 2.9% (168/5867), and 6.8% (393/5739), respectively. Wa dominated in all the viral agents considered in this study, while the Oti region recorded the highest prevalence in T. pallidum. The odds of HBV infection was 3.1 (p = 0.008) among first-time donors, while that for HCV was 2.8 (p = 0.042). For rural dwellers, donors significantly had T. pallidum (p < 0.001; OR = 2.8), HCV (p < 0.001; OR = 2.9), and HIV (p = 0.028; OR = 1.5) infections. Generally, the recipients of transfused blood were predominantly pregnant mothers, followed by children and accident victims. This study has revealed significant disparities and relatively high prevalence of TTIs in Ghana, specifically HBV, HCV, HIV and T. pallidum infections. The variations suggest the presence of unique health challenges per study area, hence the need for a tailored intervention for each study site.

Exploring Self-reported Adherence Measures to Screen for Elevated HIV Viral Load in Adolescents: A South African Cohort Study

The timely identification of ART non-adherence among adolescents living with HIV presents a significant challenge, particularly in resource-limited settings where virologic monitoring is suboptimal. Using South African adolescent cohort data (N = 933, mean age 13.6 ± 2.89 years, 55.1% female, follow-up = 2014-2018), we examined the association between elevated viral load (VL ≥ 1000 copies/mL) and seven self-reported adherence measures on missed doses, and clinic appointments -with varying recall timeframes. The best performing measures, which were significantly associated with elevated viral load in covariate-adjusted models are: any missed dose -past 3 days (sensitivity = 91.6% [95%CI: 90.3-92.8], positive predictive value (PPV) = 78.8% [95%CI: 77.2-80.4]), -past week (sensitivity = 87% [95%CI: 85.4-88.6], PPV = 78.2% [95%CI: 76.5-79.9]), -past month (sensitivity = 79.5% [95%CI: 77.5-81.4], PPV = 78.2% [95%CI: 76.4-79.9]), any past-month days missed (sensitivity = 86.7% [95%CI: 85.1-88.3], PPV = 77.9% [95%CI:76.2-79.6]), and any missed clinic appointment (sensitivity = 88.3% [95%CI: 86.8-89.8], PPV = 78.4% [95%CI: 76.8-79.9]). Combining the three best performing measures missed dose -past 3 days, -past week, and any past-year missed clinic appointment increased sensitivity to 96.4% while maintaining a PPV of about 78%. The discriminatory power of simple and easy-to-administer self-reported adherence measures in detecting elevated viral load warrants consideration in resource-limited settings and may contribute to the aims of the new Global Alliance to End AIDS in children and adolescents by 2030.
