91 unrelated patients with idiopathic or familial deep vein thrombosis (DVT) and 72 (34 with DVT) relatives from 26 families were screened for hypofibrinolysis by measuring tissue plasminogen activator antigen (t-PA:Ag) after venous occlusion (VO) for 10 and 20 min and by measuring t-PA inhibitor activity (PAI) at rest.21 healthy subjects served as controls.
Phase I and pharmacokinetic study of recombinant human granulocyte-macrophage colony-stimulating factor given in combination with fluorouracil plus calcium leucovorin in metastatic gastrointestinal adenocarcinoma.
A dysfunctional protein C (PC) molecule (Protein C Padua 2) was found in a 40-year-old man presenting with recurrent deep vein thrombosis/pulmonary embolism and a family history of thrombotic disease.
Recently it was found that the anticoagulant response to APC (APC resistance) was very weak in the plasma of 21% of unselected consecutive patients with thrombosis and about 50% of selected patients with a personal or family history of thrombosis; moreover, 5% of healthy individuals show APC resistance, which is associated with a sevenfold increase in the risk for deep vein thrombosis.
