Liver biopsy is essential in the follow-up of HCV-infected liver transplant recipients. The aim of this study was to prospectively compare percutaneous (PLB) versus transjugular liver biopsy (TLB) in the assessment of liver damage. We also explored the diagnostic value of hepatic venous pressure gradient (HVPG) to identify patients at risk of severe HCV disease recurrence after liver transplantation (LT). One hundred sixteen paired PLB and TLB (with HVPG measurement) were performed 3 or 12 months after LT in 80 patients. Concordance for necroinflammation and fibrosis was fair or good, particularly 1 year after LT (kappa > 0.6). At this point, a significant positive association was seen between the median HVPG and the fibrosis stage C hronic hepatitis C virus (HCV) infection leading to liver cirrhosis and hepatocellular carcinoma is the main indication for liver transplantation (LT) in Western countries and Japan. 1 Regretfully, recurrence of HCV infection is universal after LT, 2 and disease progression is significantly faster in immunosuppressed than in immunocompetent individuals. In liver transplant recipients, chronic HCV infection may lead to cirrhosis in as much as 30% of individuals only 5 years after LT. [3][4][5] Once liver cirrhosis is established, the cumulative probability of developing clinical decompensation is close to 50% 1 year after diagnosis and, more importantly, survival after decompensation is extremely short. 6 As a result of this accelerated course of HCV infection, longterm graft and patient survival are significantly reduced in patients undergoing LT for HCV-related cirrhosis compared with other groups. 7 Frequent liver biopsies are essential to monitor HCV-induced liver damage and are part of the routine follow-up of HCV-infected liver transplant recipients. Early histological damage after transplantation correlates with long-term outcome; in fact, the presence of significant liver fibrosis in 1-year liver biopsies identifies patients at high risk of graft loss. 3,8 In addition, assessment of liver damage is relevant to adopt therapeutic decisions, particularly because of the low efficacy and high incidence of adverse events of current antiviral therapy in this group of patients. 3,9,10
