Antiviral treatment in patients with hepatitis C virus-related cirrhosis awaiting liver transplantation.

ABSTRACT: End stage liver disease due to hepatitis C virus (HCV) infection is the most common indication for liver transplantation (LT) worldwide. Regretfully, infection of the graft by HCV occurs almost universally after LT, causing chronic hepatitis and early progression to cirrhosis in a significant proportion of recipients. Moreover, graft and patient survival are significantly worse in patients undergoing LT for HCV-related cirrhosis than in those transplanted for other indications. Therefore, many LT centers consider antiviral treatment with interferon and ribavirin the mainstay of managing recurrent HCV disease in LT recipients. The optimal time to start treatment is unclear. In most instances, treatment is initiated when histological evidence of disease recurrence, either at protocol or on-demand liver biopsies, is observed after LT. However, antiviral treatment initiated before LT is a potential option for some patients for two reasons: first, clearing or suppressing HCV before LT may reduce or eliminate the risk of recurrent hepatitis C in the transplanted liver and thereby improve survival; second, clearing HCV in cirrhotic patient may halt disease progression and avoid the need for transplantation. In this article, the results obtained by pre-transplant antiviral regimens administered to HCV-positive cirrhotic patients awaiting LT are discussed.

Project description:OBJECTIVE: The number of patients with HCV-related cirrhosis is increasing, leading to a rising risk of complications and death. Prognostic stratification in patients with early-stage cirrhosis is still challenging. We aimed to develop and validate a clinically useful prognostic index based on genomic and clinical variables to identify patients at high risk of disease progression. DESIGN: We developed a prognostic index, comprised of a 186-gene signature validated in our previous genome-wide profiling study, bilirubin (>1 mg/dL) and platelet count (<100 000/mm3), in an Italian HCV cirrhosis cohort (training cohort, n=216, median follow-up 10 years). The gene signature test was implemented using a digital transcript counting (nCounter) assay specifically developed for clinical use and the prognostic index was evaluated using archived specimens from an independent cohort of HCV-related cirrhosis in the USA (validation cohort, n=145, median follow-up 8 years). RESULTS: In the training cohort, the prognostic index was associated with hepatic decompensation (HR=2.71, p=0.003), overall death (HR=6.00, p<0.001), hepatocellular carcinoma (HR=3.31, p=0.001) and progression of Child-Turcotte-Pugh class (HR=6.70, p<0.001). The patients in the validation cohort were stratified into high-risk (16%), intermediate-risk (42%) or low-risk (42%) groups by the prognostic index. The high-risk group had a significantly increased risk of hepatic decompensation (HR=7.36, p<0.001), overall death (HR=3.57, p=0.002), liver-related death (HR=6.49, p<0.001) and all liver-related adverse events (HR=4.98, p<0.001). CONCLUSIONS: A genomic and clinical prognostic index readily available for clinical use was successfully validated, warranting further clinical evaluation for prognostic prediction and clinical trial stratification and enrichment for preventive interventions. 90 liver tissue needle biopsy specimens from patients with histologically proven cirrhosis lacking evidence and a history of hepatic decompensation or HCC.
