# The Effect of Anti-Viral Treatment of HCV Infection on Outcomes of Renal Transplant Patients with Chronic HCV Infection: A Real-World Cohort Study

## TL;DR

This study shows that treating hepatitis C before kidney transplants improves kidney survival and function in patients with chronic HCV.

## Contribution

The study provides real-world evidence that pre-transplant HCV treatment improves outcomes in kidney transplant recipients.

## Key findings

- Patients treated for HCV before transplant had lower graft failure risk (aHR: 0.656).
- Treated patients showed reduced severe renal dysfunction (aHR: 0.619).
- Mortality and liver outcomes improved but were not statistically significant.

## Abstract

Background/Objectives: Chronic hepatitis C virus (HCV) infection remains a significant comorbidity in patients with end-stage renal disease (ESRD), complicating outcomes after kidney transplantation. The anti-viral treatment of HCV infection including Direct-acting antivirals (DAAs) have transformed HCV treatment, but evidence remains limited. Methods: We conducted a retrospective, real-world cohort study using the TriNetX Analytics Network. Patients were divided into two cohorts: those who received anti-viral treatment of HCV infections before transplant (n = 982) and those who did not (n = 982), following 1:1 propensity score matching. Results: Outcomes assessed one year post-index included mortality, hepatic complications, graft failure, and serum creatinine >6 mg/dL. Anti-HCV infection treated patients had significantly lower risks of graft failure (aHR: 0.656; 95% CI: 0.434, 0.993; p < 0.001) and severe renal dysfunction (aHR: 0.619; 95% CI: 0. 0.390, 0.984; p < 0.001) compared to untreated patients. While mortality (aHR: 0.901; 95% CI: 0.728, 1.114) and liver-related outcomes trended favorably in the treated group, they did not reach statistical significance. Conclusions: Our findings demonstrate that pre-transplant anti-viral treatment of HCV infection in HCV-infected kidney transplant recipients is associated with improved graft survival and renal function.
