OBJECTIVES: To determine the prevalence and characteristics of steatosis in Alaska Natives/American Indians (AN/AI) with chronic hepatitis C virus (HCV) infection. STUDY DESIGN: This outcomes study began in 1994, and 988 AN/AI have been enrolled, including 222 study patients with a positive HCV RNA who underwent liver biopsy. METHODS: Study patients were analyzed for sex, age at biopsy, estimated length of infection, body mass index (BMI), genotype, ethanol use, HCV RNA and alanine aminotransferase levels. A pathologist blinded to patient identity and clinical data reviewed all biopsy slides for histologic activity and fibrosis. RESULTS: Moderate to severe steatosis was found significantly more often in genotype 3 than in genotypes 1 and 2 (p = 0.008). On multivariate analysis, BMI > 30 and Ishak fibrosis score > or = 2 were significantly associated with steatosis (p = 0.0013 and 0.0002, respectively), but only genotype 3 was associated with presence of moderate to severe steatosis (p = 0.008). CONCLUSIONS: Our findings in a cohort of AN/AI are consistent with results of previous studies in other groups that steatosis is associated with fibrosis in HCV and infection with genotype 3 is associated with more severe steatosis.
