Abstract We determined cholesteryl ester transfer activity in whole plasma and in lipoprotein-depleted plasma of normolipidemic subjects and of patients with severe high-density lipoprotein (HDL) deficiency: Tangier disease, lecithin:cholesterol acyltransferase (LCAT) deficiency, and "fish-eye" disease. Transfer rates in plasma were positively correlated (r = 0.950) with rates measured in the absence of the endogenous lipoproteins. This suggests that lipoprotein composition and content may not affect total cholesteryl ester transfer activity in normolipidemic and the HDL-deficient subjects. Cholesteryl ester transfer from solid-phase-bound HDL to plasma lipoproteins was decreased by 39% in fish-eye disease and 33% in LCAT deficiency but increased by 57% in Tangier disease, as compared with normal values. Changes were similar for lipoprotein-depleted plasma from the same individuals. Transfer to plasma HDL was significantly decreased in all HDL-deficient patients, whereas transfer to very-low- and low-density lipoproteins was increased only in Tangier disease. Differences in transfer rates between the patients studied appeared to reflect the LCAT activity and the need to transport cholesteryl ester rather than the HDL cholesterol concentration. Thus, the concentration of HDL in plasma does not directly affect total cholesteryl ester transfer activity in HDL deficiency.
