Blood viscosity, plasma viscosity and erythrocyte filterability were studied in 46 diabetic and in 24 hyperlipidemic patients and were compared with those of a group of normal controls; 35 diabetics were type I (IDDM, 13 of whom complication-free and 22 with micro- and macroangiopathy), 11 diabetics were type II (NIDDM, 5 of whom complication-free and 6 with micro- and macroangiopathy). Erythrocyte filterability was lower in type I and II diabetes than in controls, and was also lower in diabetics with vascular complications than in complication-free patients. Erythrocyte filterability inversely correlated with HbA1c and with plasma uric acid levels. The hyperlipidemic group included 6 type IIa, 6 type IIb, 8 type IV and 4 type V patients. All hyperlipidemic patients were examined before and during diet and drug therapy. In all the hyperlipidemic patients blood viscosity inversely correlated with HDL-cholesterol, while plasma viscosity directly correlated with plasma uric acid. All these findings suggest that some hemorheological factors can play a role in the onset and progression of vascular complications of diabetes mellitus and hyperlipidemias, and that the hemorheological changes correlate with the severity of the metabolic abnormalities.

Abstract
Blood viscosity, plasma viscosity and erythrocyte filterability were studied in 46 diabetic and in 24 hyperlipidemic patients and were compared with those of a group of normal controls; 35 diabetics were type I (IDDM, 13 of whom complication-free and 22 with micro- and macroangiopathy), 11 diabetics were type II (NIDDM, 5 of whom complication-free and 6 with micro- and macroangiopathy). Erythrocyte filterability was lower in type I and II diabetes than in controls, and was also lower in diabetics with vascular complications than in complication-free patients. Erythrocyte filterability inversely correlated with HbA1c and with plasma uric acid levels. The hyperlipidemic group included 6 type IIa, 6 type IIb, 8 type IV and 4 type V patients. All hyperlipidemic patients were examined before and during diet and drug therapy. In all the hyperlipidemic patients blood viscosity inversely correlated with HDL-cholesterol, while plasma viscosity directly correlated with plasma uric acid. All these findings suggest that some hemorheological factors can play a role in the onset and progression of vascular complications of diabetes mellitus and hyperlipidemias, and that the hemorheological changes correlate with the severity of the metabolic abnormalities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
