Background/aims: Chronic hepatitis B (CHB) and C (CHC) are commonly associated with hepatic steatosis. The aims of this study were to investigate predictors of hepatic steatosis, and their impact on inflammation and fibrosis in CHB and CHC.
Methods: Consecutive patients with either CHB or CHC who underwent a liver biopsy at The Alfred Hospital between April and September 2002 were included. Histological analysis of liver biopsies was performed by two hepatopathologists blinded to the clinical data.
Results: Ninety-one patients were analysed including 17 patients with CHB and 74 with CHC. CHC genotype 3, C-peptide, glucose and waist circumference were independent predictors of extent of Brunt steatosis grade, while CHC genotype 3, C-peptide and waist circumference were independent predictors of microvesicular steatosis grade. Alcohol intake and age were predictors of hepatic fibrosis. There was a trend toward a correlation between both Brunt steatosis and microvesicular steatosis grades and fibrosis progression rate in CHC genotype non-3.
Conclusions: Hepatic steatosis is common in chronic hepatitis B and C, and is associated with waist circumference, glucose, C-peptide and chronic hepatitis C genotype 3. Steatosis grade appears to relate to hepatic fibrosis progression rate in chronic hepatitis C genotype non-3.
