A kutatási téma leírása:
Rheological factors and increased platelet aggregation are convincingly implicated in the development of micro- and macrovascular diseases associated with diabetes mellitus. Glycemic control seems to be a major factor to determine the hemorheological consequences of diabetes. Positive associations have been found between parameters of glycemic control, fibrinogen levels and red blood cell aggregation; fibrinogen levels are also correlated to insulin resistance. The binding of fibrinogen to the GP IIb-IIIa receptor is increased in diabetic patients, and they also have a higher ratio of platelets expressing activation-dependent adhesion molecules such as activated GPIIb-IIIa, lysosomal Gp53, thrombospondin and P-selectin; plasma fibrinogen levels are also increased in diabetes. Platelets may interact with glycosylated low density lipoproteins, von Willebrand factor or immune complexes, and platelet turnover may be shortened in diabetes, thereby contributing to the observation that antiplatelet agents such as aspirin and clopidogrel have a diminished effect in these patients. We aim to study the effects of impaired glucose metabolism on hemorheological parameters, platelet activation and aggregation in patients treated with different antidiabetic regimens.
