. Lipid and carbohydrate metabolism variables were studied in twenty‐eight patients with chronic renal failure (mean GFR 7.7 ± 2.5 ml/min) and uraemic symptoms. 71% of the patients had hypertriglyceridaemia (≥ 2.2 mmol/l). Total serum cholesterol was normal while VLDL cholesterol was high and α‐lipoprotein cholesterol was low. The fractional elimination rate of Intralipid was low and inversely correlated to serum triglyceride levels. Intravenous glucose tolerance was reduced with normal or slightly increased fasting blood glucose and insulin values before and during the test. Serum triglycerides were correlated to plasma insulin but not to residual renal function or serum urea levels. The cause of hypertriglyceridaemia and lowering of α‐Lp cholesterol is not unequivocally clear. Present evidence indicate that retarded catabolism of triglyceride‐rich lipoproteins is important but accentuated release of triglyceride‐rich lipoproteins may have occurred in a number of cases. The commonly used treatment with β‐blocking agents for hypertension in chronic renal failure may accentuate certain of the metabolic responses in uraemia.
