Accelerated Hypertriglyceridemia in Patients on Continuous Ambulatory Peritoneal Dialysis - A Preventable Abnormality

Abstract

Increasing hypertriglyceridemia is a recognised complication of CAPD. To investigate the etiology lipid clearance studies using the intravenous fat tolerance test were performed in control subjects and in uremic patients before and after six months CAPD treatment. Oral carbohydrate intake was restricted and the use of hypertonic dialysate kept to a minimum. Although serum triglycerides were elevated in the uremic patients before CAPD (3.1 ± 0.3 mMol/L) no further increase occurred during therapy. Oral carbohydrate intake was restricted to 240–250 Gms/24 hrs and hypertonic dialysate to 5.7 ± 4.1% of the total. There were no significant changes in fractional removal rate of lipid. Therefore further increases in serum triglycerides in CAPD may be prevented by simple dietary manoeuvres.
