متن کاملOphthalmic manifestations of neonatal protein C deficiency.
Protein C is a vitamin K dependent plasma zymogen which acts by regulating coagulation by its specific inactivation of factors V and VII, and facilitates fibrinolysis by elevating circulating plasminogen activator levels. Protein C deficiency is a rare condition which predisposes to episodes ofpotentially blinding and lethal thromboembolism. In the newborn period, congenital protein C deficienc...
متن کاملIschemic stroke due to protein C deficiency.
Plasma protein C exerts anticoagulatory effects by inactivating factors V and VIII. Hereditary protein C deficiency is transmitted as an autosomal dominant disorder. Homozygous individuals usually develop purpura fulminans as newborns; heterozygous protein C-deficient individuals are at increased risk for venous thrombosis and pulmonary embolism. However, arterial thrombosis has been only rarel...
