Natural history of compensated cirrhosis in the Child-Pugh Class A compared between 490 patients with hepatitis C and 167 with B virus infections

Natural histories of compensated cirrhosis in the Child-Pugh class A were compared between the 490 patients infected with hepatitis C virus (HCV) and 167 patients with hepatitis B virus (HBV) who were followed for more than 1 year up to 20 years without antiviral treatment. Patients with HCV were older (median age: 59 vs. 45 years), less predominantly male (59.0% vs. 76.0%), transfused more frequently (49.2% vs. 9.0%), and had higher aminotransferase as well as lower albumin levels and fewer platelets (P<0.001 for all). Death was commoner (55.1% vs. 35.9%, P<0.001) and hepatocellular carcinoma developed more often (53.9% vs. 28.7%, P<0.001) in patients with HCV than HBV. In multivariate analysis, low albumin levels (hazard ratio: 1.65), alpha-fetoprotein (1.55), alcohol consumption (1.49), age >55 years (1.47), and retention of indocyanine green (1.39) were independent risk factors for the survival in patients with HCV, while male gender (4.43), age >45 years (2.24), retention of indocyanine green (2.14), hepatitis B e antigen (2.11), and low platelet counts (1.91) were in those with HBV. Chances for survival was significantly different (P<0.001) among patients with HCV having low (number of factors: 0-1), medium (2-3), and high risks (4-5), as well as in those with HBV having low (0-1), medium (2-4), and high risks (5-6). In conclusion, survival and development of hepatocellular carcinoma, and factors for survival, are considerably different between patients with compensated cirrhosis infected with HCV and HBV, which would need to be taken into consideration in their management and planning treatment strategies.
