The utility of aspartate aminotransferase/platelet ratio index in HIV/hepatitis C-co-infected patients.

Liver biopsy is currently the gold standard for determining the stage of liver fibrosis. There are risks associated with liver biopsy; therefore, surrogate markers to predict the severity of disease would be useful. We studied 50 patients with HIV/hepatitis C co-infection who had liver biopsies and determined that no patient with an aspartate aminotransferase/platelet ratio index (APRI) of 0.
