Prolonged prothrombin time, Factor VII and activated FVII levels in chronic liver disease are partly dependent on Factor VII gene polymorphisms

Abstract Background. Prothrombin time is a benchmark for functional assessment in cirrhosis and Factor VII levels (FVII), crucial in determining the prothrombin time, are genetically determined. Methods. We have evaluated the prothrombin time, a number of haemostatic variables synthesised by the liver (FII, FV, FVII and activated FVII, AT and fibrinogen) and two polymorphisms of the FVII gene (5′F7 and 353R/Q) in: (a) patients with liver cirrhosis ( n  = 118), (b) patients with chronic hepatitis ( n  = 102) and (c) controls ( n  = 100). Results. By one-way analyses of variance, the prothrombin time and the mean levels of the FII, FV, FVIIc, FVIIa, and AT were statistically different between…
