Abstract
Significant hypertriglyceridemia, the most common lipid abnormality in renal failure, first occurs when the creatinine clearance falls to 50 ml/min. The prevalence of hypertriglyceridemia continues to rise as creatinine clearance falls further with the highest rate developing at a creatinine clearance <10 ml/min. Hypertriglyceridemia is correlated with plasma glucagon levels but not growth hormone or insulin. Plasma cholesterol values remain normal in the face of deteriorating renal function and show no correlation with any of the hormones measured. Although all three hormones became elevated as renal function diminished, none were directly correlated with glomerular filtration rate. There was a distinct decrease in the prevalence of hyperlipidemia after 5 years of maintenance hemodialysis therapy. Plasma growth hormone and glucagon through an effect on plasma triglyceride and plasma insulin by effecting plasma cholesterol may play a role in this decline of hyperlipidemia with duration of hemodialysis.
