Hyperlipidemia in uremic children: response to peritoneal dialysis and hemodialysis
Insights
Children with kidney failure on peritoneal dialysis show high triglyceride levels, similar to those on hemodialysis. This suggests a shared cardiovascular risk for pediatric patients undergoing either dialysis treatment.
Area of Science:
- Pediatric Nephrology
- Cardiovascular Risk Assessment
- Renal Replacement Therapy
Background:
- Hyperlipidemia is a known complication in adult and pediatric patients undergoing hemodialysis.
- The cardiovascular risks associated with hyperlipidemia in children on hemodialysis are a significant concern.
- Limited data exists on lipid profiles in pediatric patients undergoing peritoneal dialysis.
Purpose of the Study:
- To investigate the prevalence of hyperlipidemia in children with chronic renal insufficiency or end-stage renal disease treated with peritoneal dialysis.
- To compare serum triglyceride concentrations in children on peritoneal dialysis versus hemodialysis, medical management, and transplantation.
- To assess the potential cardiovascular risk associated with peritoneal dialysis in pediatric patients.
Main Methods:
- A cohort of 38 children with chronic renal insufficiency or end-stage renal disease was studied.
- Patients were followed serially under various treatment modalities: medical management, hemodialysis, peritoneal dialysis, and transplantation.
- Serum triglyceride concentrations were measured and compared across the different treatment groups.
Main Results:
- Serum triglyceride concentrations were significantly higher in children on peritoneal dialysis compared to those on medical management and transplantation (P < 0.01).
- No significant difference was observed in serum triglyceride concentrations between patients on peritoneal dialysis and those on hemodialysis.
- Both dialysis modalities (peritoneal and hemodialysis) were associated with significantly elevated triglyceride levels compared to non-dialysis management or transplantation.
Conclusions:
- Hyperlipidemia is present in pediatric patients with end-stage renal disease treated with peritoneal dialysis.
- The cardiovascular risk associated with hyperlipidemia, previously noted in hemodialysis, appears to extend to peritoneal dialysis in children.
- Further research is warranted to manage dyslipidemia and mitigate cardiovascular risk in pediatric patients undergoing renal replacement therapy.
Abstract:
Hemodialysis and hyperlipidemia have been associated in both adults and children. The present study indicates hyperlipidemia in uremic children treated with peritoneal dialysis and implies that the cardiovascular risk felt to exist with hemodialysis also exists in peritoneal dialysis. Thirty-eight children with chronic renal insufficiency or end-stage renal disease were followed serially under varying conditions of medical management, hemodialysis, peritoneal dialysis, and transplantation. Serum triglyceride concentrations in patients on peritoneal dialysis were not significantly different from those in patients on hemodialysis, but both were significantly higher (P less than 0.01) than concentrations in patients on medical management and transplantation.
