Abstract

The deformability of red blood cells (RBCs) is an important rheologic factor in the maintenance of normal blood flow in the microcirculation. Contrary to the well-known relationship between hyperlipidemia and atherosclerosis, the relationship between RBC rheology and the serum lipid profile has remained controversial and obscure. Moreover, the correlation of high-density lipoprotein (HDL)-cholesterol and RBC deformability has not been fully understood. In the present cross-sectional study of 139 apparently healthy subjects, we investigated whole-cell deformability (filterability) of RBCs in relation to the lipid profile, using a nickel mesh filter with 3.2- μm pores. RBC filterability was independent of gender, age and serum levels of low-density lipoprotein (LDL)-cholesterol. The filterability was significantly proportional to the HDL-cholesterol values (r = 0.382, p < 0.01), whereas it was inversely proportional to the triglyceride levels (r = -0.259, p < 0.01). These findings may provide new insight into the role of HDL-cholesterol not only in preventing atherosclerotic progression but also in improving RBC filterability.
