Introduction This study aimed to reveal the utility of age-platelet (AP) index and aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AAR), which are non-invasive markers, in patients with chronic Hepatitis C virus (HCV) infection in prediction of fibrosis and evaluate whether viral markers could be used for that purpose or not. Methods A total of treatment-naïve 49 patients with chronic HCV who underwent liver biopsy were included in this retrospective study. Anti-HCV S/CO and HCV-RNA viral load (copy/ml) values measured simultaneously with biopsy were determined. AP index and AAR score were calculated and compared. Results Staging of liver biopsy samples of 49 HCV patients was assessed. Comparable diagnostic accuracies of AP index and AAR in prediction of significant fibrosis (F≥2) were showed with ROC curve analysis. The areas under the ROC (AUROCs) were 0.713 and 0.506 respectively. Diagnostic accuracy of API in prediction of significant fibrosis was superior to that of AAR (p=0.03). AUROC of HCV-RNA viral load in prediction of F≥2 was 0.531. Anti-HCV S/CO value (AUROC=0.464) was not found as a suitable marker in prediction of fibrosis. Conclusions AP index, AAR score and HCV viral load among non-invasive markers assessed in this study were useful in predicting significant fibrosis. Especially API was the most useful test in predicting significant fibrosis. AP index can be preferred in patients with near normal ALT values.
