INDICATORS OF HEMOSTASIS IN PATIENTS WITH CHRONIC HEPATITIS C

Abstract

Goal of the study is to reveal the particular features of hemostasis in patients with chronic hepatitis C in dynamics of natural course of disease. Materials and methods. The indices of hemostasis in 535 patients with chronic hepatitis C were assessed by the number of platelets, degree of their aggregation with the use of inductor of adenosine triphosphate and without it (spontaneous aggregation of platelets). Coagulative hemostasis was analyzed by the activated partial thromboplastin time, antitrombin III, prothrombin ratio, prothrombin time, fibrinogen concentration in plasma and international normalized ratio. Based on the number of Tr, typical for the disseminated intravascular coagulation syndrome, conditionally the patients were divided into 3 groups: I group - hypercoagulability; II - transient phase between hyper and hypocoagulation and III- hypocoagulation, which also included patients with liver cirrhosis. Results and discussion. Independent on the phase of disseminated intravascular coagulation syndrome, increase of aggregation of Tr with the growth of maximal amplitude was observed. The main part of studied indices of coagulative hemostasis indicated at the condition of hypocoagulation in patients with chronic hepatitis C - this is significant increase of activated partial thromboplastin time, prothrombin time, international normalized ratio and decrease of fibrinogen concentration in the studied groups by the phases of disseminated intravascular coagulation syndrome. Value of antitrombin III changed oppositely, it decreased, so that plasma hemostasis tends to the hypercoagulation. Conclusion. Under the chronic hepatitis C all phases of disseminated intravascular coagulation syndrome were observed with the disorder of thrombocytic coagulative hemostasis. There was followed up multidirectional change of hemostasis which obtained in the most cases character of delitescent course of disseminated intravascular coagulation syndrome.
