Background Endothelial dysfunction is a common condition in many microvascular diseases, such as Age-related Macular Degeneration (AMD) and Peripheral Arterial Occlusive Disease (PAOD). Rheopheresis therapy improves ematic viscosity, shear stress and endothelial function while decreasing fibrinogen, LDL-cholesterol and alpha-2-macroglobulin levels. Objective To evaluate the therapeutic efficacy of rheopheresis in patients with microcirculatory diseases. Materials and Methods Eight patients (7 male and 1 female) were treated with rheopheresis: 3 males were affected by AMD, 4 male and 1 female by uremia and PAOD. We used Membrane Differential Filtration (MDF) with an ethinylvinylalcohol copolymer membrane as plasmafiltrator. Patients with AMD were treated once a week for ten weeks. Patients affected with PAOD were treated twice weekly for 3 weeks and then were placed on a once-a-week program. Results In all treated patients with AMD, visual acuity improved. In all patients affected with PAOD, we observed a complete resolution of pain; 3 out of 5 had a complete remission of ulcers. There was partial reduction of ulcers in the other patients and no adverse effects were observed. Conclusion: Rheopheresis is a safe, effective form of hemorheotherapy

Abstract. Summary: The term “LDL hypothesis” is frequently used to describe the association of low-density lipoprotein cholesterol (LDL-cholesterol, LDL-C) and cardiovascular (CV) events. Recent data from genetic studies prove a causal relation between serum LDL-C and CV events. These data are in agreement with mechanistic molecular studies and epidemiology. New randomised clinical trial data show that LDL-C lowering with statins and a non-statin drug, ezetimibe, reduces CV events. We therefore believe that the “LDL-hypothesis” has been proven; the term appears to be outdated and should be replaced by “LDL causality”.

SummaryPlatelet aggregation, platelet lipid composition and plasma lipoprotein concentrations were measured each week in a group of seventeen alcoholics, without overt liver disease, for one month, following acute, total alcohol withdrawal. The platelets were initially hypoaggregable but, within 1-2 weeks of cessation of drinking, they became hyperaggregable and then gradually returned towards normal values. Hyperaggregability could not be explained by increases in either the cholesterol or the arachidonic acid content of the platelets. Plasma very-low-density lipoprotein cholesterol levels remained high throughout the study, but the initially raised levels of high-density lipoprotein (HDL) cholesterol fell by 26%. Low-density lipoprotein (LDL) cholesterol concentration rose by 10% after two weeks of withdrawal but then returned to about the starting level. The resulting changes in the plasma LDL-cholesterol: HDL-cholesterol ratio, which had increased by more than 50% after two weeks of abstinence, essentially paralleled the time course of enhanced platelet reactivity in all but four of the alcoholics. These findings suggest that alterations in plasma lipoprotein concentrations during acute alcohol withdrawal may be a contributory factor to the haemostatic disorders present in such patients.
