RESUMEN
In 2016, World Health Organization (WHO) introduced global targets for the care and management of hepatitis C virus (HCV) infection to eliminate hepatitis C as a public health threat by 2030. Despite significant improvements in testing and treatment, in 2020 only 23% of all persons infected with HCV globally were diagnosed. We explore examples from global hepatitis C programs in Georgia, Rwanda, and Nigeria that have used decentralized and integrated models to increase access to HCV testing. Georgia established the world's first national hepatitis C elimination program in 2015. In 2022, 2.6 million people (80% of the adults) have been screened for antibodies for HCV infection, and 80,000 persons with HCV virus detected were treated. To achieve these results, Georgia implemented HCV core antigen (HCVcAg) testing, utilization of point-of-care HCV RNA, and simplification of HCV viremia detection by qualitative HCV RNA. Rwanda was the first country in sub-Saharan Africa to commit to HCV elimination in 2018, and as of 2022 it has achieved its screening target of 7 million people and initiated approximately 60,000 patients on hepatitis C treatment by rapid decentralization and integration of HCV services. In Nigeria, the integrated near-point-of-care testing approach in Nasarawa state has been effective in expanding access to HCV viremia testing and enabling the possibility of same-day testing and treatment initiation. Examples of decentralization and integration of HCV testing and linkage to care in Georgia, Rwanda and Nigeria could help inform effective strategies to reach 2030 hepatitis C elimination goals in other countries.
RESUMEN
OBJECTIVES: Given limited data on factors associated with hepatitis C virus (HCV) treatment discontinuation and failure in low- and middle-income countries, we aimed to describe patient populations treated for HCV in five countries and identify patient groups that may need additional support. DESIGN: Retrospective cohort analysis using routinely collected data. SETTING: Public sector HCV treatment programmes in India (Punjab), Indonesia, Myanmar, Nigeria (Nasarawa) and Vietnam. PARTICIPANTS: 104 957 patients who initiated treatment in 2016-2022 (89% from Punjab). PRIMARY OUTCOMES: Treatment completion and cure. RESULTS: Patient characteristics and factors associated with outcomes varied across countries and facilities. Across all patients, median age was 40 years (IQR: 29-52), 30.6% were female, 7.0% reported a history of injecting drugs, 18.2% were cirrhotic and 4.9% were coinfected with HIV. 79.8% were prescribed sofosbuvir+daclastasvir. Of patients with adequate follow-up, 90.6% (89,551) completed treatment. 77.5% (69,426) of those who completed treatment also completed sustained virological testing at 12 weeks (SVR12), and of those, 92.6% (64 305) were cured. In multivariable-adjusted models, in most countries, significantly lower treatment completion was observed among patients on 24-week regimens (vs 12-week regimens) and those initiated in later years of the programme. In several countries, males, younger patients <20 years and certain groups of cirrhotic patients were less likely to complete treatment or be cured. In Punjab, treatment completion was also lower in those with a family history of HCV and people who inject drugs (PWID); in other countries, outcomes were comparable for PWID. CONCLUSION: High proportions of patients completed treatment and were cured across patient groups and countries. SVR12 follow-up could be strengthened. Males, younger people and those with decompensated cirrhosis on longer regimens may require additional support to complete treatment and achieve cure. Adequate programme financing, minimal user fees and implementation of evidence-based policies will be critical to close gaps.
