Thrombin Generation Assay to Assess Thrombotic Risk in Nephrotic Patients (TGANephrotic)
Thrombin Generation Assay to Assess Thrombotic Risk and the Evolution of the Hypercoagulability Profile of Patients With Nephrotic Syndrome
The thromboembolic risk is increased during the nephrotic syndrome (NS) with an incidence of deep vein thrombosis 15%, pulmonary embolism of 10-30% and renal vein thrombosis of 25-37%. There is a hemostatic imbalance with urinary leakage of anticoagulant factors and increased hepatic synthesis of procoagulant factors, platelet hyperaggregability and a decrease in fibrinolytic activity. However, the identification of patients requiring anticoagulant prophylaxis remains imprecise.The thromboembolic risk is higher when the NS is related to extramembranous glomerulonephritis comparatively to others glomerulopathies. The reason of this difference is not still known. This risk increase with SN's severity and therefore with the decrease of albuminemia. Moreover, few studies have evaluated anticoagulant treatment efficacy during a NS, which clinical benefit depends also on hemorrhagic risk specific of each patient. Thus, the determination of the thrombotic risk and the modalities of anticoagulation are variable and perfectible during the NS.
We propose to use the thrombin generation test (TGT) to quantify the thromboembolic risk in patients with a NS and to follow its evolution during prophylactic anticoagulation and after remission of NS.
