Percutaneous liver biopsy is the gold standard for staging hepatic fibrosis of hemodialysis patients with chronic hepatitis C before renal transplantation or antiviral therapy. Concerns exist, however, about serious post-biopsy complications. To evaluate a more simple approach using standard laboratory tests to predict hepatic fibrosis and its evolution, we studied 279 consecutive hemodialysis patients with chronic hepatitis C and a baseline biopsy. Among them, 175 receiving antiviral therapy underwent follow-up biopsy to evaluate the histological evolution of fibrosis. Multivariate analysis of routine laboratory tests at baseline showed the aspartate aminotransferase-to-platelet ratio index was an independent predictor of significant hepatic fibrosis. The areas under curves of this ratio to predict fibrosis stages F2-4 were 0.83 and 0.71 in the baseline and follow-up sets; and 0.75 and 0.80 respectively, for patients with sustained or non-sustained virological response groups in the follow-up sets. By a judicious setting of cut-off levels for the baseline and non-sustained groups, and the sustained virological response group, almost half and 60 percent of the baseline and follow-up sets could be correctly diagnosed without biopsy. Our study found the aminotransferase-to-platelet ratio index is accurate and reproducible for assessing hepatic fibrosis in hemodialysis patients with chronic hepatitis C. Applying this simple index could decrease the need of percutaneous liver biopsy in this clinical setting.
