Cytokeratin(CK)18 is an intermediary filament protein, expressed in hepatocytes, which is proteolytically cleaved during liver damage. M30 epitope of cytokeratin18(CK18-M30) is involved at different levels in apoptotic pathways. The aim of this study to investigate the diagnostic accuracy of cytokeratin 18-apoptosin M30 fragments (CK18-M30) as non-invasive method of liver fibrosis assessment and their correlation to METAVIR score. Serum concentrations of CK18-M30 were measured by ELISA in One hundred and sixty eight chronic hepatitis C patients (112 males and 56 females). Results showed that serum concentrations of CK18 were significantly increased in a stepwise fashion from A0 to A3 and from F0 to F4.There was highly significant positive correlation between CK18 and fibrosis stages (r = 0.881 & p < 0.001) and activity grades (r = 0.881 & p < 0.001). Also, serum CK18 correlated positively with serum levels of transaminases (r = 0.355 & p < 0.05). CK18 was correlated positively with viral level (r = 0.3 & p < 0.05). It was concluded that Elevated serum C...
