ABSTRACT
To assess the relation between serum AST/ALT ratio [AAR] and hepatic fibrosis and cirrhosis associated with chronic hepatitis C. A cross sectional study. The study was conducted in the department of medicine Military Hospital Rawalpindi from Sep 2004 - Feb 2005. Fifty diagnosed patients of chronic hepatitis C were selected whose liver biopsy was performed as a workup plan fro treatment. Serum AST/ALT ratio [AAR] was determined and degree of liver fibrosis noted on histopathology, using Knodell scoring system. ANOVA was applied to study the difference in AAR in different stages of liver fibrosis. The mean AAR was found to be higher with each increasing stage of liver fibrosis. The mean AAR in cirrhotics [1.34] was significantly higher compared to noncirrhotics [0.77], p<0.001. AAR >/= 1 had 100% sensitivity and negative predictive value in distinguishing cirrhotic from non-cirrhotic patients with 87% specificity and 45% positive predictive value. There is only a modest relation between AAR and early hepatic fibrosis [stages 1-3] in patients with chronic hepatitis C, while AAR is significantly higher in patients with advanced fibrosis/ cirrhosis
