LENA, Ana  and  RAYMONDO, Stella. Evaluation about coagulation physiological inhibitors in type 2 diabetic patients. Acta bioquím. clín. latinoam. [online]. 2007, vol.41, n.2, pp.213-218. ISSN 0325-2957.

Diabetes mellitus is associated with disturbances in hemostasis, which may contribute to the development of diabetic vascular disease. Coagulation tests were performed both in diabetic patients and healthy individuals in Uruguay. The results obtained were compared. Diabetic patients were 100, with ages between 42 and 79 years, 49 females and 51 males. Reference population were 130 healthy individuals between 37 and 78 years, 73 females and 57 males. Prothrombin time (PT), fibrinogen( Fib), protein C (PC), protein S (PS), antithrombin III (ATIII) and plasminogen activator inhibitor (PAI) were measured on citrated plasma. PT and Fib were determined nephelometrically, PC, ATIII y PAI were measured cromogenically and PS was determined by coagulometry. Coagulation physiological inhibitors outcomes such as PS and ATIII showed significantly lower levels in the diabetic patient than in the healthy person, and at the same time, Fib and PAI, which are procoagulant factors, have significantly higher concentrations in the diabetic patient than in the healthy person. These findings permit to assess that an impaired haemostatic balance is present in the diabetic population, which may contribute to the hypercoagulability that accompanies a high percentage of these patients.

Keywords : diabetes; procoagulant state; hypercoagulability; vascular disease.
