Abstract |
The relationship between the secundaer hyperlipidaemia and pathological platelet activation was examined in 40 insulin-treated diabetic patients without nephropathy and 21 with nephropathy. Diabetic nephropathy was recorded with the measurements of serum creatinine, serum beta 2-microglobulin, and urine albumin excretion. Haemostasis and lipoprotein metabolism were characterized with determination of platelet aggregation, plasma beta thromboglobulin, thromboxane-B2, serum triglyceride, HDL and LDL cholesterol concentration, respectively. In the normalbuminuric group serum triglyceride and thromboxane-B2 positively correlated. In the nephropathic group serum cholesterol and beta thromboglobulin, as well as LDL and beta thromboglobulin, finally, LDL and thromboxane-B2 showed significant positive correlation. In diabetic patients without nephropathy platelet aggregate ratio was in positive correlation with the serum triglyceride, while the ED50-S elevated with the increase of serum cholesterol and LDL. The nephropathic group exhibited no such parallelisms. However, there were significant correlations of LDL with serum creatinine in both groups of diabetic patients. Our results seem to indicate that the increase of LDL could be associated with the change of LDL structure. Interactions of modified LDL and the platelet membrane might contribute to the platelet hyperactivation both in the nephropathy-free and nephropathic cases.
