The liver is the cornerstone of the coagulation system. The physiology of blood coagulation is closely linked to liver function as the liver synthesizes most of the factors of the coagulation cascade and fibrinolytic proteins.

The objective of this study was to evaluate coagulation abnormalities associated with chronic liver diseases and determine the coagulation abnormalities using various coagulation studies [prothrombin time (PT), activated partial thromboplastin time (APTT), bleeding time (BT), clotting time (CT), and platelet count].

This study included 300 patients clinically diagnosed with liver disease and who were divided into three categories – cirrhosis, hepatitis, and other liver diseases. The coagulation tests PT, APTT, BT, CT, and platelet count were performed and the results were evaluated in groups.

Out of the 300 patients, 156 were diagnosed with cirrhosis, 75 were of viral hepatitis, and 69 were of other liver diseases. About 62% (186/300) had prolonged PT. About 39.3% (118/300) had prolonged APTT. The BT was prolonged in 34% (102/300), while CT was prolonged in 10.6% (32/300). Thrombocytopenia was seen in 46% (138/300) patients.

We concluded that various abnormalities of coagulation tests vary greatly with different liver disorders, duration of the disorders, and their severity. Prolongation of PT and APTT in advancing liver cirrhosis indicates damage to the liver parenchyma resulting in decreased production of coagulation proteins with increased risk of bleeding tendencies, which can be detected before these ensue.
