    BACKGROUND: Prevention, screening and diagnostic services for hepatitis B virus (HBV) and hepatitis C virus (HCV) can prevent morbidity and mortality in people receiving HIV care. However, there is limited information about the availability of HBV and HCV services at HIV clinics globally. METHODS: The International epidemiology Databases to Evaluate AIDS (IeDEA) conducted surveys of service delivery and practices at participating HIV treatment centers from seven regions. We used 2023 survey data to measure availability of HBV vaccination, HBV and HCV screening, HBV surface antigen (HBsAg), HBV DNA, HCV antibody, HCV RNA testing. Multivariable logistic regression models were used to test associations of site characteristics with HBV and HCV services. RESULTS: HBV vaccination was available on-site at 67.7% of 204 HIV treatment sites. Screening for HBV and HCV at HIV care enrollment was reported by 72.1% and 50% of sites, respectively. HBsAg, HBV DNA, HCV antibody and HCV RNA testing were available on-site at 77%, 47.6%, 61.8% and 44.6% of sites, respectively. Sites serving predominately rural (vs. urban) populations were less likely to report on-site availability of HBV DNA (odds ratio (OR):0.07; 95% confidence interval (CI):0.01-0.68;P=0.02), HCV antibody (OR=0.18; 95% CI:0.04-0.92;P=0.04) and HCV RNA (OR=0.10; 95% CI:0.01-0.90;P=0.04) testing. CONCLUSION: Life-saving services such as HBV vaccination, HBsAg and HCV antibody testing were available on-site at most HIV treatment sites participating in the IeDEA network. Lower availability at rural sites suggests that expansion of services is important to eliminate HBV and HCV as public health problems in people receiving HIV care.

    Tuberculosis Diagnosis, Treatment, and Prevention Services for Children Living with HIV in Low- and Middle-Income Countries: A Multiregional Site Survey.

    BACKGROUND: Tuberculosis (TB) remains a leading cause of morbidity and mortality for children living with HIV (CLHIV), with gaps in TB screening, diagnostics, management, and TB preventive therapy (TPT). We investigated reported practices in these domains at sites caring for CLHIV in low- and middle-income countries (LMICs) within the International Epidemiology Databases to Evaluate AIDS (IeDEA) consortium. METHODS: We implemented a site survey from September 2020 to February 2021, querying pre-pandemic practices. This analysis included sites in LMICs providing care for CLHIV that diagnosed TB in 2019. We analyzed responses using descriptive statistics and assessed regional differences using Fisher's exact or chi-square tests. RESULTS: Of 238 IeDEA sites, 227 (95%) responded and 135 met the inclusion criteria. Most (90%) reported screening for TB at HIV care enrollment. Access to diagnostics varied significantly by region, including nucleic acid amplification testing (NAAT, range 67-100%), mycobacterial culture (range 43%-83%), and drug susceptibility testing (range 30%-82%) (P < .001). On-site TB treatment was high (90%). Reported stock-outs occurred for isoniazid (23/116, 20%) and other TB medications (11/114, 9.6%, range 0%-33%, P = .008). TPT provision ranged 50%-100% (P < .001). Six months of isoniazid was the most common TPT regimen for children (88%). Shorter TPT regimens were uncommon (0.9%-2.8%), as were regimens for multidrug-resistant TB exposure (4.6%). CONCLUSIONS: Overall reported availability of NAAT and integrated TB/HIV treatment for CLHIV cared for at these IeDEA sites in LMICs is encouraging but varies by context. Heterogeneous implementation gaps remain-particularly for drug susceptibility testing, TPT delivery, and TPT regimens-which may impede TB prevention, management, and successful outcomes for CLHIV, warranting continued close attention over time and as global TB care guidelines and services evolve.
