title: Predictors of liver-related complications in patients with chronic hepatitis C.
abstract: Chronic hepatitis C is the leading cause of decompensated liver disease requiring liver transplantation and a major cause of hepatocellular carcinoma (HCC). In liver clinic series, about 20% of those chronically infected with hepatitis C virus (HCV) develop cirrhosis over 20 years. From epidemiological data, however, it is clear that certain subgroups of patients are more likely to develop liver-related complications than others. Both host and viral factors have been implicated in individual susceptibility to adverse outcomes. The impact of host factors, such as alcoholism, is now well defined, and viral factors, such as genotype and viral load, appear to be less influential than previously considered. Coinfections with HIV, hepatitis A virus (HAV) and hepatitis B virus (HBV) may influence the rate of fibrotic progression and the subsequent development of complications in patients with chronic hepatitis C. The stage of fibrosis on biopsy and biochemical markers, such as a low serum albumin, can help identify patients who are more likely to develop complications. The role of the immune system in modifying the course of HCV is only now being defined. This editorial explores the role of host and viral factors in the development of liver-related complications in HCV-infected individuals.
