Individual free fatty acids in patients with liver disease.

The total free fatty acids, blood glucose, and individual free fatty acids were studied in 8 patients with viral hepatitis and 13 with cirrhosis. The results were compared with those obtained in 9 normal control subjects. Free fatty acids were significantly elevated in liver patients as compared with normal controls. A fall in free fatty acids following ingestion of amino acids and dextrose was noted in normal subjects as well as liver patients. Glucose tolerance test, when done on patients with liver disease, was abnormal in most cases. Highly significant differences were found in the composition of individual free fatty acids in liver patients as compared with normal subjects. Arachidonic and linoleic acids were decreased, while monounsaturated and saturated fatty acids were increased in patients with viral hepatitis and cirrhosis. No significant changes were noted in the percent composition of individual free fatty acids following ingestion of amino acids and dextrose.
