Abstract

Liver cirrhosis leads to a protido-synthetic impairment that alters the levels of blood clotting factors and haemostasis. The aim of this study was to assess the alterations of haemostatic parameters in the evolution of liver cirrhosis scored according to Child's classification, with Pugh's modifications. Thirty-seven patients suffering from alcoholic and non-alcoholic liver cirrhosis, representing stages A5, A6, B7, B8 and C10, were tested for the main blood clotting parameters, i.e. prothrombin time, factor VII, partial activated thromboplastin time, fibrinogen, plasminogen, alpha 2-antiplasmin and physiological inhibitors [antithrombin III (ATIII), protein C (PC), protein S (PS)]. No variations were observed between substages A5 and A6 in any of the parameters, except for coagulation inhibitor levels. Most parameters showed a progressive decrease in stages B and C of the disease. The most significant alterations were found in the physiological coagulation inhibitors, with a sharper decrease in PC and AT III level and a lesser decrease in the level of PS through stages A5 and B8: this evidence could assume an important biological and diagnostic significance.
