Abnormal fat metabolism in chronic renal failure.

The serum triglyceride and cholesterol levels, the cholesterol and triglyceride concentrations in the lipoprotein fractions, as also postheparin lipoprotein-lipase activity (PHLA) were determined in 18 haemodialysis-patients with chronic renal failure. Hypertriglyceridaemia and hypocholesterolaemia were found together with increased VLDL- and LDL + HDL-triglyceride and decreased HDL-cholesterol concentrations. At 10 min after administration of heparin, enzyme activity was normal, at 20 min it was abnormally decreased.
