Özet
It is believed that thrombotic activity in nephrotic syndrome is due to an imbalance between procoagulant/thrombotic and anticoagulant/antithrombotic factors in plasma. The aim of this study was to investigate the hypercoagulability risk in childhood minimal change disease and to find possible protective mechanisms with respect to hemostasis. Twenty-six children with minimal change disease were enrolled in this study. All patients were evaluated during an attack and on remission. The control group consisted of 33 healthy children. During the attack period, prothrombosis parameters, total lipid, cholesterol, fibrinogen levels and platelet count increased significantly compared to levels in the remission period. This denotes that hyperviscosity increases thrombosis tendency. In the attack period, the significant increase of prothrombin fragments 1+2 which shows thrombin formation and thrombin-antithrombin complex which causes prothrombin activation, are an indication of increased thrombosis risk. Five patients with lupus anticoagulant present and 7 patients with activated protein-C resistance ratios carried an increased thrombosis risk. D-dimer level of fibrinolytic factors significantly increased during the attack period. These findings emphasize the existence of thrombotic activity causing the activation of the fibrinolytic system. The significant increase in protein-C activity in these patients represents one of the protective mechanisms against thrombosis. The decrease in tissue plasminogen activator and antiplasmin indicates the protective role of fibrinolytic activity. Consequently, an increase in the protein-C activity is one of the protective mechanisms. The fibrinolytic system also plays an important role in preventing thrombotic activity in these patients. © 2004 Kluwer Academic Publishers.
