    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: To eliminate cervical cancer (CC), access to and quality of prevention and care services must be monitored, particularly for women living with HIV (WLHIV). We assessed implementation practices in HIV clinics across sub-Saharan Africa (SSA) to identify gaps in the care cascade and used aggregated patient data to populate cascades for WLHIV attending HIV clinics. METHODS: Our facility-based survey was administered between November 2020 and July 2021 in 30 HIV clinics across SSA that participate in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. We performed a qualitative site-level assessment of CC prevention and care services and analysed data from routine care of WLHIV in SSA. RESULTS: Human papillomavirus (HPV) vaccination was offered in 33% of sites. Referral for CC diagnosis (42%) and treatment (70%) was common, but not free at about 50% of sites. Most sites had electronic health information systems (90%), but data to inform indicators to monitor global targets for CC elimination in WLHIV were not routinely collected in these sites. Data were collected routinely in only 36% of sites that offered HPV vaccination, 33% of sites that offered cervical screening and 20% of sites that offered pre-cancer and CC treatment. CONCLUSIONS: Though CC prevention and care services have long been available in some HIV clinics across SSA, patient and programme monitoring need to be improved. Countries should consider leveraging their existing health information systems and use monitoring tools provided by the World Health Organization to improve CC prevention programmes and access, and to track their progress towards the goal of eliminating CC.

    INTRODUCTION: Adolescent and youth-friendly health services (AYFHS) have been promoted as a best practice for adolescents and young people living with HIV (AYLH). However, thorough descriptions of AYFHS for AYLH remain scarce. We sought to characterize adolescent-friendly HIV services in a global paediatric research consortium. METHODS: Cross-sectional data were collected from 16 global sites in the Adolescent and Young Adult Network of IeDEA (AYANI) of the International epidemiology Databases to Evaluate AIDS consortium between August 2020 and October 2022 using a standardized site assessment tool that collected data on clinic, patient and provider characteristics, differentiated care, and transition to adult services processes. Descriptive analyses characterized the health services available across the participating sites, using frequencies and proportions for categorical variables and medians and interquartile range for continuous variables. Data were analysed using RStudio. RESULTS: Overall, 13 of 16 sites (81%) reported having dedicated adolescent services, which most often consisted of dedicated clinic days (62%, n = 8/13), primarily offered on weekdays. Across all sites, nurses and counsellors delivered services to adolescents. Over half of all clinics (69%, n = 11/16) reported offering health education to adolescents to facilitate adolescent health literacy. Peer educators and navigators were involved in delivering services at 62% of sites, primarily in those with dedicated adolescent services (69%, n = 9/13). There was limited integration of sexual and reproductive health services into HIV clinics for adolescents. With 63% of clinics conducting pregnancy screening, 50% providing family planning methods and 38% providing cervical cancer screening. Under half of all HIV clinics screened for physical abuse or violence (44%, n = 7/16) and sexual abuse or rape (38%, n = 6/16). A low proportion of clinics screened for risk factors related to young key populations, including drug use (56%, n = 9/16), homelessness (38%, n = 6/16) young men having sex with men (31%, n = 5/16) and transactional sex (31%, n = 5/16). Mental health screening for concerns was variable. CONCLUSIONS: Findings suggest gaps in AYFHS for AYLH across the HIV clinics included in this analysis. There is a vital need to design health services for AYLH that are accessible, equitable, and effective and meet the global standards for delivering high-quality healthcare to adolescents.

    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.

    BACKGROUND: While people with HIV (PWH) start antiretroviral treatment (ART) regardless of CD4 count, CD4 measurement remains crucial for detecting advanced HIV disease and evaluating ART programmes. We explored CD4 measurement (proportion of PWH with a CD4 result available) and prevalence of CD4 <200 cells/µL at ART initiation within the International epidemiology Databases to Evaluate AIDS (IeDEA) global collaboration. METHODS: We included PWH at participating ART programmes who first initiated ART at age 15-80 years during 2005-2019. We described proportions of PWH (i) with CD4 (measured within 6 months before to 2 weeks after ART initiation); and (ii) among those with a CD4, with CD4 <200; by year of ART initiation and region. RESULTS: We included 1,355,104 PWH from 42 countries in 7 regions; 63% were female. Median (interquartile range) age at ART initiation was 37 (31-44) in men and 32 (26-39) in women. CD4 measurement initially increased, or remained stable over time until around 2013, but then declined to low levels in some regions (Southern Africa, except South Africa: from 54 to 13%; East Africa 85 to 31%; Central Africa 72 to 20%; West Africa: 91 to 53%; and Latin America: 87 to 56%). Prevalence of CD4<200 declined over time in all regions, but plateaued after 2015 at ≥30%. CONCLUSIONS: CD4 measurement has declined sharply in recent years, especially in sub-Saharan Africa. Among those with a CD4, the prevalence of CD4 <200 remains concerningly high. Scaling up CD4 testing and securing adequate funding are urgent priorities.

    Gone But Not Lost: Implications for Estimating HIV Care Outcomes When Loss to Clinic Is Not Loss to Care.
    (2020-Jul) Edwards JK; Lesko CR; Herce ME; Murenzi G; Twizere C; Lelo P; Anastos K; Tymejczyk O; Yotebieng M; Nash D; Adedimeji A; Edmonds A; Department of Epidemiology & Population Health, Albert Einstein College of Medicine, Bronx, NY.; Departments of Medicine and Epidemiology & Population Health, Albert Einstein College of Medicine, Bronx, NY.; Centre for Infectious Disease Research in Zambia (CIDRZ), Lusaka, Zambia.; Institute for Implementation Science in Population Health, City University of New York, New York, NY.; Rwanda Military Hospital, Kigali, Rwanda.; Institute for Global Health and Infectious Diseases, University of North Carolina at Chapel Hill, Chapel Hill, NC.; Kalembelembe Pediatric Hospital, Kinshasa, Democratic Republic of the Congo.; Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD.; From the Department of Epidemiology, University of North Carolina at Chapel Hill, Chapel Hill, NC.; Centre Hospitalo, Universitaire de Kamenge, Bujumbura, Burundi.
    BACKGROUND: In some time-to-event analyses, it is unclear whether loss to follow up should be treated as a censoring event or competing event. Such ambiguity is particularly common in HIV research that uses routinely collected clinical data to report the timing of key milestones along the HIV care continuum. In this setting, loss to follow up may be viewed as a censoring event, under the assumption that patients who are "lost" from a study clinic immediately enroll in care elsewhere, or a competing event, under the assumption that people "lost" are out of care all together. METHODS: We illustrate an approach to address this ambiguity when estimating the 2-year risk of antiretroviral treatment initiation among 19,506 people living with HIV who enrolled in the IeDEA Central Africa cohort between 2006 and 2017, along with published estimates from tracing studies in Africa. We also assessed the finite sample properties of the proposed approach using simulation experiments. RESULTS: The estimated 2-year risk of treatment initiation was 69% if patients were censored at loss to follow up or 59% if losses to follow up were treated as competing events. Using the proposed approach, we estimated that the 2-year risk of antiretroviral therapy initiation was 62% (95% confidence interval: 61, 62). The proposed approach had little bias and appropriate confidence interval coverage under scenarios examined in the simulation experiments. CONCLUSIONS: The proposed approach relaxes the assumptions inherent in treating loss to follow up as a censoring or competing event in clinical HIV cohort studies.

    INTRODUCTION: In 2016, the World Health Organization recommended differentiated service delivery (DSD) as a client-centred approach to simplify HIV care in frequency and intensity, thus reducing the clinic visit burden on individuals and HIV programmes. We describe the scale of DSD implementation among HIV facilities in low- and middle-income countries (LMICs) in Latin America, Africa and the Asia-Pacific before the COVID-19 pandemic. METHODS: We analysed facility-level survey data from HIV care facilities participating in the International epidemiology Databases to Evaluate AIDS consortium in 2019. We used descriptive statistics to summarise the availability of DSD, multi-month dispensing (MMD) and DSD for HIV treatment models. We explored factors associated with DSD implementation using multivariable models. RESULTS: We included 175 facilities in the Asia-Pacific (n = 30), Latin America (n = 8), Central Africa (n = 21), East Africa (n = 74), Southern Africa (n = 28) and West Africa (n = 14). Overall, 133 facilities (76%) reported implementing DSD. Of these, 91% offered DSD for HIV treatment, 61% for HIV testing and 59% for antiretroviral therapy (ART) initiation. The most common duration of ART refills for clinically stable clients was 3MMD, (70%), followed by monthly (14%) and 6MMD (10%). Facility-based individual models were the most frequently available DSD for the HIV treatment model (82%), followed by client-managed group models (60%). Out-of-facility individual models were available at 48% of facilities. Facility-based individual models were particularly common among facilities in East (92%) and Southern Africa (96%). Facilities in medium and high HIV prevalence countries, and those with 3MMD, were more likely to implement DSD. CONCLUSIONS: In 2019, DSD was available in most HIV care facilities globally but was not evenly implemented across regions and HIV services. Most offered facility-based DSD for HIV treatment models and 3MMD for clinically stable clients. Efforts to expand DSD for HIV testing and ART initiation and to offer longer MMD can improve long-term retention in care of people living with HIV in LMICs, while further alleviating the operational burden on healthcare services. These findings from the pre-COVID-19 era underline the need for strengthening DSD in HIV care, which remains at the centre of current efforts towards client-centred care.
