Hemofilia

·         Haemophilia A is a recessive X-linked genetic disorder involving a lack of functional clotting Factor VIII and represents 80% of haemophilia cases.
·         Haemophilia B is a recessive X-linked genetic disorder involving a lack of functional clotting Factor IX. It comprises approximately 20% of haemophilia cases.[11]
·         Haemophilia C is an autosomal genetic disorder (i.e. not X-linked) involving a lack of functional clotting Factor XI. Haemophilia C is not completely recessive, asheterozygous individuals also show increased bleeding.[12]

Trombina

Schematic diagram of the blood coagulation and protein C pathways. In the blood coagulation pathway, thrombin acts to convert factor XI to XIa, VIII to VIIIa V to Va, fibrinogen to fibrin. In addition, thrombin promotes platelet activation and aggregation via activation of protease-activated receptors on the cell membrane of the platelet. Thrombin also cross over into the protein C pathway by converting protein C into APC. APC in turn converts factor V into Vi, and VIIIa into VIIIi. Finally APC activates PAR-1 and EPCR.
