[Some parameters of hemostasis and fibrinolysis in diabetic patients].
The aim of our study was to estimate selected parameters of hemostasis and fibrinolysis in diabetic patients with vascular complications and obesity. The investigation was carried out in 23 type 1 diabetic subjects aged 17-56 ys, in 25 type 2 diabetic patients aged 41-69 ys and in 38 healthy persons: 16 "young"--aged 32.5 +/- 13.2 ys and 22 "old"--aged 56.2 +/- 9.4 ys. The following parameters were determined: glycaemia, HbA1c, blood level fibrinogen, euglobulin clot lysis time, plasminogen activator inhibitor (PAI-1) activity, microalbuminuria, triglyceride, total, HDL- and LDL-cholesterol concentration. Plasma fibrinogen level was elevated in type 2 diabetic subjects, and the highest concentrations were noted in patients with retinopathy or arterial hypertension, in overweight persons and--surprisingly--in type 1 diabetic subjects with nephropathy and coronary vascular disease (CVD). There were also positive correlations between fibrinogen level and systolic blood pressure (r = 0.3413, p < 0.02), diastolic blood pressure (r = 0.3809, p < 0.002) and microalbuminuria (r = 0.3552, p < 0.05). The mean euglobulin clot lysis time was prolonged in type II diabetics in comparison to the control group, especially in obese subjects. The highest activity of PAI-1 was found in overweight controls (28.87 +/- 6.24 Au/ml, p < 0.002). PAI-1 activity was also slightly increased in type 1 diabetic patients, especially with the symptoms of diabetic neuropathy, nephropathy or CHD, in comparison to the other groups. Our results seem to confirm the disturbed balance between coagulation and fibrinolysis--towards and increased risk of a prothrombotic state --in both--obese and diabetic patients--especially with advanced vascular complications.
