[Free fatty acids in the serum of patients with alcoholism]

Blood free fatty acids and their composition were investigated in 25 alcohol abusers hospitalized for detoxication. Blood samples were collected at the admission to the hospital and following detoxication therapy. Free fatty acids were assayed with Dole's technique whereas their composition with gas chromatography. Liver functioning was evaluated with the aid of the following tests: AspAT, AlAT, AP, bilirubin concentration, and thymol test. An increase in free fatty acids concentration was seen in 12 out of 25 patients prior to detoxication. Blood serum free fatty acids were within normal limits in all except one patient after detoxication. A decrease in linoleic acid levels was seen in both total fatty acids and free fatty acids before detoxication. It is more marked in total fatty acids than in free fatty acids and persists after detoxication. Linoleic acid content in free fatty acids returns to the normal values following detoxication. An increase in oleic acid level accompanying a decrease in linoleic acid concentration is probably secondary to the stimulation with hydrogen excess formed during alcohol fermentation.
