Abstract

Abstract: Background and Aims: The impact of hepatitis C virus (HCV) infection on patient survival after renal transplantation was worse. Previously, we found that continuous HCV infection was a significant independent risk factor for actuarial survival (especially at ≥20 years after the transplant procedure) among Japanese renal allograft recipients. This study evaluates the impact of HCV and of the new direct acting antivirals (DAAs) on patient outcomes in renal allograft recipients. Method: We studied 46 cases (28 males, 18 females; 37 living-donor cases, 9 deceased-donor cases; mean follow-up period 305 months ranging from 2 to 420 months) out of the 315 renal transplanted patients who underwent the first renal transplantation in Kanazawa Medical University since 1974. They had antibodies against HCV: 11 were positive for HCV RNA and received DAAs (Group A, all of them genotype 1b); 27 were HCV RNA positive and did not receive any treatment (Group B); 8 were negative for HCV RNA (Group C) (Fig.1). Results: All Group A patients had HCV RNA negativity after 2-12 weeks of treatment started, and 11 (100%) achieved a sustained virological response (SVR) at 24 weeks. All of them had no adverse effects by the use of DAAs. In this cohort, no patients in Group A died. On the other hand, 15 (55.5％) of 27 in Group B and 3 (37.5%) of 8 in Group C died. Causes of death among Group B were liver cirrhosis (5 cases), hepatocellular carcinoma (2 case), infections complicated with chronic hepatitis (6 cases) in chronic phase, fibrosing cholestatic hepatitis due to HCV (1 case) after surgery, and cardiovascular disease (1 case). The patient survival rate was significantly higher in Group A patients who received DAAs by Kaplan- Meier life table method (Log Rank test, Kay-square 11.7, p=0.004) (Fig.2). Conclusion: Our results support the notion that continuous HCV infection was a harmful and that new DAAs were efficient and safe to treat HCV infection after renal transplantation.
