CAUNEDO ALMAGRO, Patricia. Alterations of hemostasis in the diabetes mellitus. Rev Cubana Hematol Inmunol Hemoter [online]. 2005, vol.21, n.1. ISSN 0864-0289.

Diabetes mellitus is classified into 2 types according to its pathogenesis: type 1 accounts for less than 10 % of the total of patients, whereas type 2 is the most common in the population of diabetic patients. Multiple alterations of hemostasis have been found among the patients suffering from this disease. The studies conducted in platelets, blood coagulation and fibrinolysis have allowed to assert that these disorders are probably an important factor in the prethrombotic state of these patients. The investigations carried out with platelets have shown a platelet hyperreactivity, an increase of the procoagulant activity of platelets. On the other hand, most of the authors coincide at present that diabetes mellitus is a state of hypercoagulability, which is based on several investigations on the disease and on the coagulation mechanism that prove the rise of fibrinogen, factor VII and von Willebrand factor, as well as of the markers of activation of this system. Besides, alterations such as the increase of the plasminogen activator inhibitor and of the fibrinolysis inhibitor activated by thrombin have been demonstrated in the fibrinolytic system. In this paper, some mechanisms are presented that may explain the alterations in the hemostasis and that may contribute to the development of thrombotic complications that are observed in these patients.

Palabras clave : Diabetes mellitus; coagulation; platelets; fibrinolysis.
