Hemostasis is traditionally defined as a physiological response to blood vessel injury and bleeding, which entails a co-ordinated process involving the blood vessel, platelets, and blood clotting proteins (i.e. coagulation factors). Hemostasis can be divided into primary and secondary components. The former rapidly initiates after endothelial damage and is characterized by vascular contraction, platelet adhesion, and formation of a soft aggregate plug. The latter is initiated following the release of tissue factor and involves a complex sequence of events known as the blood coagulation cascade, encompassing serial steps where each coagulation factor activates another in a chain reaction that culminates in the conversion of fibrinogen to fibrin. Patients carrying abnormalities of the coagulation cascade (i.e. deficiencies of coagulation factors) have an increased bleeding tendency, where the clinical severity is mostly dependent upon the type and the plasma level of the factor affected. These disorders also impose a heavy medical and economic burden on individual patients and society in general. The aim of this article is to provide a general overview on the pathophysiology, clinics, diagnostics, and therapy of inherited disorders of coagulation factors.

Abstract

Hemostasis is traditionally defined as a physiological response to blood vessel injury and bleeding, which entails a co-ordinated process involving the blood vessel, platelets, and blood clotting proteins (i.e. coagulation factors). Hemostasis can be divided into primary and secondary components. The former rapidly initiates after endothelial damage and is characterized by vascular contraction, platelet adhesion, and formation of a soft aggregate plug. The latter is initiated following the release of tissue factor and involves a complex sequence of events known as the blood coagulation cascade, encompassing serial steps where each coagulation factor activates another in a chain reaction that culminates in the conversion of fibrinogen to fibrin. Patients carrying abnormalities of the coagulation cascade (i.e. deficiencies of coagulation factors) have an increased bleeding tendency, where the clinical severity is mostly dependent upon the type and the plasma level of the factor affected. These disorders also impose a heavy medical and economic burden on individual patients and society in general. The aim of this article is to provide a general overview on the pathophysiology, clinics, diagnostics, and therapy of inherited disorders of coagulation factors.
