Popis: This study was carried out to evaluate the association of genetic polymorphism -670AG in the promoter of Fas gene as well as serum biomarkers aspartate aminotransferase (AST) platelet ratio index (APRI) and AST/alanine aminotransferase (ALT) with significant fibrosis and cirrhosis in chronic hepatitis C patients. Seventy-nine patients with chronic hepatitis C in addition to 80 age- and sex-matched healthy controls were evaluated for genetic polymorphism -670AG of Fas gene by polymerase chain reaction-restriction fragment length polymorphism and serum biomarkers APRI and AST/ALT in relation to significant fibrosis and cirrhosis diagnosed by liver biopsy.Genetic polymorphism -670AG in Fas gene was associated with significant liver fibrosis and cirrhosis. Heterozygous mutation was found in 11.4% of patients and 10% of controls, while homozygous mutation was found only in 7.6% of patients. Odds ratio (OR) was statistically not significant (OR=1.93, 95% confidence interval=0.76-4.92). Mean values of APRI and AST/ALT were significantly higher in patients with (F3-F4) compared with those with (F0-F2). (p-value0.001 for APRI and p=0.007 for AST/ALT). In addition, APRI showed a better sensitivity than AST/ALT for prediction of significant fibrosis.Genetic polymorphism -670AG of Fas gene was associated with significant fibrosis and cirrhosis in chronic hepatitis C patients. APRI and AST/ALT are independent predictors for significant fibrosis. APRI showed a better sensitivity than AST/ALT for prediction of significant fibrosis. Moreover, APRI can be used as an index to exclude liver cirrhosis without performing liver biopsy.
