Abstract

BACKGROUND:

Hepatic steatosis, a common histological finding in hepatitis C virus (HCV)-infected patients, is associated with severity of fibrosis. The prevalence and significance of steatosis in patients coinfected with human immunodeficiency virus (HIV) and HCV are not well characterized.

METHODS:

To determine the prevalence and severity of steatosis, a single pathologist evaluated liver-biopsy samples from 106 patients coinfected with HIV and HCV but without hepatitis B infection (negative results for hepatitis B surface antigen) for findings associated with steatosis or steatohepatitis and viral hepatitis. Medical records were reviewed retrospectively to elucidate risk factors for steatosis.

RESULTS:

Steatosis was present in 56% of biopsy samples, with moderate to severe grades in 9%. Severity of steatosis was associated with fibrosis (odds ratio [OR], 1.84 [95% confidence interval (CI), 1.06-3.20]; P=.03) but not with necroinflammation. In multivariate analysis, the severity of steatosis was associated with lower levels of high-density lipoprotein cholesterol (OR, 0.71 per 10-mg/dL increase [95% CI, 0.52-0.95]; P=.02), higher body-mass index (OR, 1.30 per kg/m2 increase [95% CI, 1.13-1.49]; P<.001), and the presence of lipodystrophy (OR, 3.82 [95% CI, 1.13-12.88]; P=.03). There was a trend toward an association between the severity of steatosis and fibrosis in multivariate analysis (OR, 1.69 [95% CI, 0.91-3.16]; P=.10).

CONCLUSIONS:

In patients coinfected with HIV and HCV, hepatic steatosis is common and associated with more-advanced fibrosis. Lower levels of high-density lipoprotein cholesterol, higher body-mass index, and lipodystrophy are potentially modifiable risk factors associated with the severity of steatosis.
