OBJECTIVE: The aim of this study was to understand the relationship between cardiovascular disease (CVD) risk and liver steatosis and fibrosis among people with HIV (PLWH) at least 40 years of age on antiretroviral therapy (ART) in low and middle-income countries (LMIC). DESIGN: We used cross-sectional behavioral and clinical data collected during study enrollment visits in 2020-2022 for the Sentinel Research Network of International epidemiology Databases to Evaluate AIDS (SRN of IeDEA). METHODS: Ten-year CVD risk was calculated using 2019 WHO nonlaboratory and laboratory models. Transient elastography was used to assess liver disease. Presence of steatosis and significant fibrosis were defined by controlled attenuation parameter (CAP) at least 248 dB/m and liver stiffness measurement (LSM) at least 7.1 kPa, respectively. Participants with viral hepatitis, hazardous alcohol consumption, and unsuppressed HIV viral load were excluded from the analysis. Logistic regression was used to estimate odds ratios, adjusting for study site, CD4 + T cell count, stavudine and didanosine exposure, and in models stratified by sex and geographic region. RESULTS: There were 1750 participants from nine LMIC. Median CVD risk was 3% for both nonlaboratory and laboratory-based models. Adjusted odds ratios (ORs) for steatosis and significant fibrosis associated with laboratory CVD risk (≥10 vs. <5%) were OR = 1.83 [95% confidence interval (95% CI) = 1.21-2.76; P = 0.004] and OR = 1.62 (95% CI = 0.85-3.07; P = 0.14), respectively. Associations of CVD risk with steatosis were stronger in men and among participants at study sites outside Africa. CONCLUSION: Higher CVD risk was associated with steatosis but not with significant fibrosis in PWH in our LMIC cohort.

INTRODUCTION: People with HIV (PWH) are vulnerable to mental health and substance use disorders (MSDs), but the extent to which these are associated with other non-communicable diseases in ageing PWH populations remains poorly documented. We assessed comorbidities associated with symptoms of MSD among PWH ≥40 years in the Sentinel Research Network (SRN) of the International epidemiology Database to Evaluate AIDS (IeDEA). METHODS: Baseline data collected between June 2020 and September 2022, from 10 HIV clinics in Asia, Latin America and Africa contributing to the SRN, were analysed. Symptoms of MSDs and comorbidities were assessed using standardized questionnaires, anthropometric and laboratory tests, including weight, height, blood pressure, glucose, lipids, chronic viral hepatitis and liver transient elastography. HIV viral load, CD4 count and additional routine clinical data were accessed from participant interview or medical records. HIV and non-HIV clinical associations of mental illness symptoms and unhealthy substance use were analysed using logistic regression. Mental illness symptoms were defined as moderate-to-severe depressive symptoms (PHQ-9 score >9), moderate-to-severe anxiety symptoms (GAD-7 >9) or probable post-traumatic stress disorder (PCL-5 >32). Unhealthy substance use was defined as ASSIST score >3, or AUDIT ≥7 for women (≥8 for men). RESULTS: Of 2614 participants assessed at baseline study visits, 57% were female, median age was 50 years, median CD4 was 548 cells/mm CONCLUSIONS: Improved integration of MSD and comorbidity services in HIV clinical settings, and further research on the association between MSD and comorbidities, and care integration among older PWH in low-middle-income countries, are required.

INTRODUCTION: Tuberculosis (TB) is a leading infectious cause of death globally. It is the most common opportunistic infection in people living with HIV, and the most common cause of their morbidity and mortality. Following TB treatment, surviving individuals may be at risk for post-TB lung disease. The TB Sentinel Research Network (TB-SRN) provides a platform for coordinated observational TB research within the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. METHODS AND ANALYSIS: This prospective, observational cohort study will assess treatment and post-treatment outcomes of pulmonary TB (microbiologically confirmed or clinically diagnosed) among 2600 people aged ≥15 years, with and without HIV coinfection, consecutively enrolled at 16 sites in 11 countries, across 6 of IeDEA's global regions. Data regarding clinical and sociodemographic factors, mental health, health-related quality of life, pulmonary function, and laboratory and radiographic findings will be collected using standardised questionnaires and data collection tools, beginning from the initiation of TB treatment and through 12 months after the end of treatment. Data will be aggregated for proposed analyses. ETHICS AND DISSEMINATION: Ethics approval was obtained at all implementing study sites, including the Vanderbilt University Medical Center Human Research Protections Programme. Participants will provide informed consent; for minors, this includes both adolescent assent and the consent of their parent or primary caregiver. Protections for vulnerable groups are included, in alignment with local standards and considerations at sites. Procedures for requesting use and analysis of TB-SRN data are publicly available. Findings from TB-SRN analyses will be shared with national TB programmes to inform TB programming and policy, and disseminated at regional and global conferences and other venues.
