We assessed the effect of different hepatic conditions such as fibrosis, steatosis and necroinflammatory activity on liver stiffness as measured by transient elastography in HIV/HCV-coinfected patients. We studied all consecutive HIV/HCV-coinfected patients who underwent liver biopsy and elastography between January 2007 and December 2008. Liver fibrosis was staged following METAVIR Cooperative Study Group criteria. ⋯ However, in a multiple regression analysis, steatosis and fibrosis were the only independent variables significantly associated with liver stiffness. With a cut-off of 9.5 kPa to distinguish patients with F ≤ 2 from F ≥ 3, elastography led to a significantly higher number of misclassification errors (25%vs 5%; P = 0.014), most of which were false positives for F ≥ 3. Our study suggests that the correlation between liver stiffness and fibrosis as estimated by transient elastography may be affected by the presence of hepatic steatosis in HIV/HCV-coinfected patients.
