[Comparative study of peripheral circulation, lipid metabolism and hemocoagulation in families with atherosclerosis and diabetes mellitus].

Aim: The study of peripheral circulation (PC) in patients with atherosclerosis (AS), diabetes mellitus (DM) type I and II as well as their close relatives to clarify correlations between circulatory disorders, disturbances of lipid metabolism (LM) and hemocoagulation.

Materials And Methods: The patients and their relatives were divided into 3 groups: with AS, DM type I and II. Individuals without relevant hereditary predisposition served control. A total of 564 subjects were examined. Thermography (TG), TV capillaroscopy of the nail bed (TVCNB), measurements of total blood cholesterol (TBC), high density lipoproteins (HDLP) cholesterol, triglycerides, coagulation time, plasma recalcification, free heparin, fibrinogen concentration, calculation of the atherogenic and prothrombin indices were conducted.

Results: Microcirculation suffered most of all, especially in patients and their relatives with AS and DM type I. TVCNB detected morphological changes of the capillaries confirmed by TG. DM patients and their relatives, especially those with DM type I had most distinct morphological shifts.

Conclusion: The above PC disorders result from lipid metabolism and hemocoagulation abnormalities affecting blood rheology. In DM patients and their relatives especially in those with DM type I specific alterations of the capillary structure in DM and hereditary predisposition to DM are a contributing factor.
