Plasma total lipid phosphorus, individual phospholipid fractions, free and esterified cholesterol, triglycerides and nonesterified fatty acids were fractionated by thin-layer chromatography and determined in bilharzial hepatic fibrosis patients (57 cases) and normal controls (25 cases). Significant diminutions were encountered in the total and the individual phospholipids, especially the lysolecithin fraction in the 3 groups of patients studied. Total and esterified cholesterol and triglycerides showed significant decreases, especially in moderate and late cases. NEFA, on the other hand, did not reveal any change from normal level in either moderate, late or mixed cases. Such findings may be attributed to malabsorption, lack of energy, insufficiency of required precursors as well as impaired synthesis by the liver.
