Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Among the hemodialysis units, the global incidence of HCV infection ranges from 1.2% to 2.9%. Data regarding the long-term risk of reinfection among hemodialysis patients achieving SVR are limited. To our best knowledge, only one study assessed the long-term negativity of serum HCV RNA in hemodialysis patients who achieved SVR after IFN-based therapies. With a median follow-up of 48 months following SVR, the life-time cumulative survival for HCV RNA negativity was 86% among the 121 participants who were on maintenance dialysis. Furthermore, the life-time cumulative survival for HCV RNA negativity was 95% among the 45 participants who underwent renal transplantation from HCV-negative donors. Because the literatures regarding the long-term follow-up of viral outcome, the patient numbers to be recruited are still limited, and all studies are focused on IFN-based treatment, we aim to assess the long-term risk of HCV reinfection in hemodialysis patients attaining SVR by IFN-based or IFN-free therapies.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Hepatitis C virus (HCV) infection is an important public health problem. Compared to the global prevalence of HCV infection to be around 1.0%, the prevalence of HCV infection in hemodialysis patients is around 10%. The high prevalence of HCV infection in hemodialysis patients receiving long-term renal replacement therapy may be reasoned by the nosocomial transmission in hemodialysis units. If chronic HCV infection is left untreated, the survival, hospitalization and the quality of life are significantly compromised in hemodialysis patients. In contrast, the survival is improved following successful treatment-induced HCV clearance Interferon (IFN)-based therapy is the treatment of choice for hemodialysis patients with HCV infection in earlier years. However, the treatment responses are far from ideal and the treatment-emergent adverse events (AEs) are frequently encountered, making the global treatment uptake rate by IFN-based therapies to be only 1.5%. Based on the excellent efficacy and safety, IFN-free direct acting antivirals (DAAs) have been the mainstay of therapy for HCV. Furthermore, the world health organization (WHO) has set the goal of global HCV elimination by 2030. The microelimination of HCV among hemodialysis patients is also listed as the prioritized target by WHO.

The updated definition of sustained virologic response (SVR) is the presence of serum undetectable HCV RNA level at week 12 after the stopping of antiviral therapy. However, the consensus in Taiwan mandates that hemodialysis patients who achieve SVR at off-therapy week 24 can be moved from HCV-segregated zone to cleat zone in hemodialysis unit, instead of the global definition of off-therapy week 12. The delay of bed-transfer from HCV-infective zone to clear zone might increase the risk of reinfection in hemodialysis patients achieving SVR. Therefore, we aim to assess the risk of short-term of HCV reinfection in hemodialysis patients achieving SVR at week 12 after antiviral therapy, which may be great relevance and importance for health policy making.

Among the hemodialysis units, the global incidence of HCV infection ranges from 1.2% to 2.9%. Data regarding the long-term risk of reinfection among hemodialysis patients achieving SVR are limited.

Because the literatures regarding the long-term follow-up of viral outcome, the patient numbers to be recruited are still limited, and all studies are focused on IFN-based treatment, we aim to assess the long-term risk of HCV reinfection in hemodialysis patients attaining SVR by IFN-based or IFN-free therapies.
