    Abstract:
    Plasma fatty acids and lipid peroxidation were studied in human atherosclerosis. Analysis of fatty acids in 16 controls and 32 hyperlipidemic patients showed, in the latter, a decrease in saturated fatty acids, especially palmitic and stearic acids, and an increase in unsaturated fatty acids, especially arachidonic acid. Compared to hyperlipidemic patients without arterial injury, patients with arterial injury exhibit a significant increase in malonaldehyde (MDA). In the former, MDA concentrations are significantly increased compared to controls. Therefore, peroxidation of unsaturated fatty acids may have a deleterious effect on arteries in atheroma, through the release of toxic endoperoxydes and the metabolization of arachidonic acid into thromboxane, which is a platelet aggregator. Lipid peroxidation can also be demonstrated in other diseases: we found very high MDA concentration in 11 alcoholic patients (alcoholic hepatitis, cirrhosis) and 6 patients with inflammatory conditions such as Crohn disease.
