Cholesterol metabolism in patients with chronic renal failure on hemodialysis.

Premature atherosclerosis is a major concern in patients on chronic dialysis and the identification of risk factors is important for preventive and interventional strategies. Other than the recognized atherogenic lipoprotein levels, little is known about overall cholesterol metabolism in patients on chronic hemodialysis (HD) and the best therapeutic intervention is still being debated. Therefore, we investigated intestinal cholesterol absorption, cholesterol and bile acid synthesis, and non-cholesterol plasma sterols in eight patients on dialysis and compared the results to those of 16 healthy male controls matched for body mass index and dietary cholesterol intake.
