Patients with type 2 diabetes and abdominal fat patterning displayed higher plasma activities of clotting factors VII and VIII as well as increased plasma levels of fibrinogen and von Willebrand factor antigen, when compared with not only healthy normal weight controls, but also with diabetic patients at normal body weight. Mechanisms associating abdominal obesity with the above mentioned prothrombotic changes are only partially elucidated and may differ according to the individual haemostatic variable. Actually, according to data in the literature and authors' observations increased plasma factor VII activity is mainly associated with increased plasma triglyceride level, while the hepatic synthesis of fibrinogen as well as the synthesis and release of endothelia-derived von Willebrand factor are stimulated by cytokines originating in the visceral adipose tissue. The relationship between the presently investigated hemostatic variables and features of the metabolic syndrome are less obvious than in the previously recorded association of metabolic risk factors with plasma levels of plasminogen activator inhibitor. |
