Fatty acid composition of plasma lipids in gout.

The changes occurring in the fatty acid composition of the plasma lipids were studied in gout. The major changes consisted in an increase in oleic acid and a decrease in linoleic and arachidonic acids in most lipid fractions of plasma; linoleic acid is unchanged in plasma cholesteryl esters and in FFA while arachidonic acid does not vary only in FFA. These changes are not related either to diet or to the age of patients and are similar to those reported in atherosclerotic and diabetic patients, as well as those with cardiac ischemia. The variations observed are directly influenced by the ratio essential fatty acids/monoenoic acids and all factors affecting this ratio.
