    Abstract:
    BACKGROUND/AIMS: Steatosis in patients with chronic hepatitis C (CHC) may be the result of both viral and host factors. To evaluate: (1) the relationship between steatosis and either host or viral factors; (2) the correlation between steatosis and fibrosis in patients with CHC. METHODS: A consecutive series of 349 patients were evaluated for steatosis. At liver biopsy, patients were tested for virological, and laboratory analysis and questioned for alcohol consumption. RESULTS: Logistic regression analysis demonstrated that steatosis was independently associated with genotype 3a (odds ratio, OR 3.5), alcohol intake at the time of biopsy (OR 2.6) and age >35 years (OR 2.7). In multivariate analysis the presence of fibrosis was associated with past alcohol abuse (OR 3.7), and age older than 44 years (OR 2.2). Overall, a weak correlation was found between grade of steatosis and fibrosis score (r=0.861, P=0.05), which disappeared excluding patients without past or current alcohol intake. A direct correlation emerged between grade of steatosis and both 'grading' and 'staging' only in patients with genotypes other than 3a. CONCLUSIONS: Genotype 3a is the main risk factor for steatosis in patients with CHC. The grade of steatosis correlated with both grading and staging only in patients with genotypes other than 3a and this relationship is strictly linked to alcohol consumption.
