RESUMEN
Background/objectives: The area of hypercoagulability in cirrhosis and its potential contribution to certain clinical aspects have received a lot of attention. The clinical manifestations of the hemostatic disorders of cirrhosis have been traditionally related to bleeding due to multiple procoagulant factor defects, excessive fibrinolysis, and thrombocytopenia. Aim: Assess the function of blood coagulation in patients with chronic liver diseases and improve the knowledge of the pathophysiology of haemostasis. Patients and methods: This is a prospective case-control study which was conducted at outpatient clinic of internal medicine dept., Minia University Hospital, Minia Governorate, during the period from March 2017 to August 2018. Results: Protein C and S concentrations decreased significantly in Group (II A, II B, and IIC) compared to control and also, Group (II C) decreased significantly than Group (II A, II B). Regarding Thrombin fragments (F 1+2), Child score A patients had significantly higher concentration compared to the other three groups. However, as regards, Thrombin-antithrombin (TAT), Child score C group had a significantly higher level compared to other groups. Conclusion: Thrombin fragments and thrombin antithrombin complex are considered as the main specific markers for thrombin generations which were elevated strongly depending upon the pathogenesis and the severity of the liver diseases.
