Peculiarities of oxidative stress in the plasma of patients with familial hypercholesterolemia

Abstract

Plasma level of lipid-standardized vitamin E is decreased, while the concentration of inflammatory transmitters C3a(desArg) and C5a(desArg) is elevated in heterozygous familial hypercholesterolemia caused by apoB,E-receptor deficiency. Leukocytes isolated from these patients exhibit enhanced spontaneous aggregation of superoxide anion generation and are resistant to activation with exogenous platelet activation factor (10 -6 M).
