Several noninvasive tests have been proposed to predict cirrhosis in patients with chronic hepatitis C, but not in patients with non-alcoholic steatohepatitis (NASH). We assessed whether noninvasive laboratory tests designed to predict the risk of cirrhosis in patients with chronic hepatitis C virus (HCV) infection could be used in patients with NASH. The subjects were 50 patients with biopsy-proved NASH and 100 age- and sex-matched patients with HCV. Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio (AAR), age-platelet (AP) index, AST-to-platelet ratio index (APRI), cirrhosis discriminant score (CDS), and the hepatitis C antiviral long-term treatment against cirrhosis (HALT-C) model were calculated. The areas under the receiver-operating characteristic curves of the AAR, AP index, APRI, CDS, and HALT-C model for predicting cirrhosis were respectively 0.813, 0.877, 0.786, 0.949, and 0.908 in patients with NASH and 0.555, 0.652, 0.761, 0.782, and 0.782 in patients with HCV. A CDS cutoff value of less than 5 misclassified none of the 9 patients with NASH who had cirrhosis, while a value of more than 8 misclassified none of the 41 patients with NASH without cirrhosis. With the HALT-C model, a cutoff value of less than 0.6 classified non-cirrhotic NASH, while a cutoff value of 0.97 or higher classified cirrhotic NASH. The use of CDS and HALT-C model could avoid liver biopsy for predicting cirrhosis in 60 and 48% of the patients with NASH, respectively. Noninvasive laboratory tests designed to predict cirrhosis in patients with HCV are also useful in patients with NASH.
