Implementation of Microelimination Strategy in Eradication of Chronic Hepatitis C Infection in Patients with Hemophilia in the Northern region of Serbia: Is Eradication Possible?

BACKGROUND: Treating HCV in people with hemophilia prevents the development of end-stage liver disease (ESLD) and hepatocellular carcinoma (HCC) and greatly increases the quality of life for people living with hemophilia. There are many obstacles in reaching the WHO goal of globally eradicating HCV by 2030, mainly its scale, complexity, and implementation. That is why many countries have implemented a micro-elimination strategy: a pragmatic elimination approach in populations with the most efficacy. The aim of this publication is to present the morbidity and mortality rates, the clinical course and treatment outcomes of chronic HCV infection in people with hemophilia (PwH), as well as to show an example of a successfully conducted HCV micro-elimination strategy among people with hemophilia in the Province of Vojvodina. METHODS: A retrospective, single-center study, performed using medical documentation of all registered PwH in the Clinical Center of Vojvodina from 1994. until 2020. It included 74 hemophilia patients, out of which 32 were patients with hemophilia and chronic HCV infection. RESULTS: The mean age of HCV-positive positive people with hemophilia (PwH) was 42.3 years, with the duration of infection of 30–35 years. Co-infection with HIV was observed in 6.25% of cases. Furthermore, 18.75% of patients had spontaneous HCV elimination, and 75% were treated with antiviral protocols. Cirrhosis developed in 21.87% with an incidence rate of 0.6 per 100 patient-years. After treatment with Pegylated IFN and ribavirin (RBV), 58.3% achieved SVR. Side effects of IFN-based therapy regimens were recorded in 20.8% of treated (PwH). In 37.5% PWH, DAA protocols were administered, and these patients achieved SVR. HCV- PwH have a statistically higher mortality rate than non-infected people with hemophilia. Among the HCV-positive PwH, hemophilia-related deaths were 6.25%, and HCV-related deaths were 9.37%. Currently, in the Registry of PwH in Vojvodina, there are no patients with active HCV infection. CONCLUSION: The micro-elimination strategy in the subpopulation of PwH was successfully implemented in Vojvodina by hematologists and infectious diseases specialists in close collaboration.
