Abstract 17147: Hypertriglyceridemia Associated With Peritoneal Dialysis

Abstract

Introduction: Chronic kidney disease and kidney replacement therapies (KRT) are associated with increased incidence of dyslipidemia and cardiovascular disease. In patients with chronic kidney disease, uremic dyslipidemia can cause qualitative and quantitative changes in the lipoproteins due to inflammation, malnutrition, and proteinuria. The major abnormalities include increase in triglyceride (TG) rich particles and reduced activity of lipoprotein lipase (LP). In this case, we present a patient who developed worsening hypertriglyceridemia after KRT changed to peritoneal dialysis (PD). Clinical Course: A 65-year-old female with end stage renal disease (ESRD) on PD, mixed dyslipidemia and hypertension who presented for elevated triglycerides 2084 mg/dL. Patient had been on KRT for 5 years and was switched to PD for the past 3 years. TG prior to starting PD was 203 mg/dL. Patient was started on atorvastatin 40 mg daily, Omega-3 Fatty Acids 2 g twice daily and substituted hypertonic glucose exchange with icodextrin for dialysate. TG improved to 391 mg/dL with these changes. Discussion: Hypertriglyceridemia is a common condition with management include lifestyle modifications and medications. In uremic dyslipidemia, there is increase in triglyceride-rich lipoproteins, small dense low-density lipoprotein particles, increased lipoprotein (a), and decreased high density lipoprotein. The pathogenesis of hypertriglyceridemia seen in PD is not well understood. There is overproduction of very low-density lipoprotein, peritoneal protein loss through drained dialysate, carbohydrate loading from the glucose based dialysate and reduced LP function contributing to the hypertriglyceridemia. This patient’s TG worsened when she was switched to PD from hemodialysis. TG improved with lifestyle modifications, medications and change in dialysate fluids. Hypertriglyceridemia associated with PD is rare, but it is important to recognize and treat to reduce risk of pancreatitis and cardiovascular complications.
