Background & Aims: The risk of hepatocellular carcinoma (HCC) is reduced but not eradicated among patients with hepatitis C virus (HCV)-induced advanced hepatic fibrosis who attained sustained viral response (SVR). We aimed to assess the risk of cirrhosis-related complications in this specific group of patients., Methods: Data from previously reported Western cohort studies including patients with chronic HCV infection and bridging fibrosis or cirrhosis who attained SVR were pooled for survival analyses on the individual patient level. The primary endpoint was HCC and the secondary endpoint was clinical disease progression, defined as liver failure, HCC or death., Results: Included were 1000 patients with SVR. Median age was 52.7 (IQR 45.1-59.7) years, 676 (68%) were male and 842 (85%) had cirrhosis. Median follow-up was 5.7 (IQR 2.9-8.0) years. Fifty-one patients developed HCC and 101 had clinical disease progression. The cumulative 8-year HCC incidence was 1.8 (95% CI 0.0-4.3) among patients with bridging fibrosis and 8.7% (95% CI 6.0-11.4) among those with cirrhosis (p=0.058). Within the cirrhosis group, the 8-year HCC incidence was 2.6% (95% CI 0.0-5.5) among patients <45years, 9.7% (95% CI 5.8-13.6) among patients from 45-60years, and 12.2% (95% CI 5.3-19.1) among patients >60years of age at start of therapy (p=0.006). Multivariable Cox analyses indicated that higher age, lower platelet count and diabetes mellitus were independently associated with development of HCC. After 8years 4.2% (95% CI 0.1-8.3) of patients with bridging fibrosis and 15.8% (95% CI 12.3-19.3) of patients with cirrhosis experienced clinical disease progression (p=0.007)., Conclusions: Patients with HCV-induced cirrhosis and SVR showed an annual risk of approximately 1% for HCC and 2% for clinical disease progression. Therefore, to prevent HCC surveillance, chronic HCV infection should preferably be treated before cirrhosis has developed., Lay Summary: Patients with cirrhosis who were able to eradicate their chronic HCV infection remain at substantial risk of primary liver cancer. The risk of liver cancer increases with higher age, laboratory makers suggesting more severe liver disease, and presence of diabetes mellitus. Also after successful antiviral therapy patients with HCV-induced cirrhosis should thus remain included in follow-up for early detection of liver cancer., (Copyright © 2016 European Association for the Study of the Liver.

HCV has been classified into no fewer than six major genotypes and a series of subtypes. Each HCV genotype is unique with respect to its nucleotide sequence, geographic distribution, and response to therapy. Genotypes 1, 2, and 3 are common throughout North America and Europe. HCV genotype 4 (HCV-4) is common in the Middle East and in Africa, where it is responsible for more than 80% of HCV infections. It has recently spread to several European countries. HCV-4 is considered a major cause of chronic hepatitis, cirrhosis, hepatocellular carcinoma, and liver transplantation in these regions. Although HCV-4 is the cause of approximately 20% of the 170 million cases of chronic hepatitis C in the world, it has not been the subject of widespread research. Therefore, this document, drafted by a panel of international experts, aimed to review current knowledge on the epidemiology, natural history, clinical, histological features, and treatment of HCV-4 infections., (Copyright © 2010 European Association for the Study of the Liver.

Background/aims: Risks and benefits of antiviral therapy in HCV cirrhosis with portal hypertension are poorly known., Methods: We performed a randomized controlled trial in 102 HCV patients with compensated cirrhosis and portal hypertension: 51 received 1 microg/kg/week of Pegylated-interferon alpha-2b and 51 Pegylated-interferon plus 800 mg/day of ribavirin up to 52 weeks., Results: By intention-to-treat analysis, five patients on monotherapy and eleven on combination therapy achieved a sustained virological response (9.8% vs. 21.6%, p=0.06). The response was more frequent for genotypes 2 or 3 than genotype 1 (66.6% vs. 11.3%, p=0.001). Genotype 1, who had low viral load at start of therapy, were HCV-RNA negative at 4 weeks, and were adherent to the scheduled therapy had a higher probability of sustained virological response. Patients with sustained virological response had less disease events compared to nonresponders (6.2% vs. 38.3%, p=0.03 by log rank test) during follow-up., Conclusions: In HCV cirrhosis with portal hypertension Peg-interferon plus ribavirin is a feasible treatment. Although the rate of viral eradication is modest, tailoring by genotype and early viral response allows to keep patients on treatment who are more likely to have viral eradication. Patients with viral eradication have fewer disease complications during follow-up.

Background/aims: Liver biopsy represents the gold standard to establish a diagnosis in all liver patients, but its current position in chronic viral hepatitis is questioned. We aimed to create a consensus on best practice of use of liver biopsy in the management of chronic HCV infection., Methods: We applied the Delphi method to 12 clinical scenarios of chronic HCV infection, to assess the extent of agreement (consensus measurement) and to resolve disagreement (consensus development) on the appropriateness of liver biopsy., Results: Among 108 chosen hepatologists, 61 (56.5%) accepted to participate to the first-round survey. In four patients the majority of experts (from 61.4 to 86.2%) agreed not to perform liver biopsy; in two cases an equivalent opinion was found, and in the remaining six scenarios the majority of experts would have recommended a biopsy. No expert recommended liver biopsy in all cases, while most agreed for an histological evaluation of 4 to 8 cases. At the second round, 36 experts (59%) submitted ballots. Fifty-four out of 431 (12.6%) original judgments were changed with equal distribution among different scenarios., Conclusions: Our survey showed a great divergence of management of similar patients and should provide a stimulus for an evidence-based evaluation of liver histology in chronic HCV infection.
