Abstract:
Background:Cardiovascular complications related to dyslipidemia are common in patients with chronic kidney disease, particularly among those undergoing peritoneal dialysis (PD). Glucose-based PD solutions may contribute to metabolic disturbances such as insulin resistance and altered lipid profiles. Elevated erythrocyte membrane oleic acid (OA) levels have been observed in PD patients compared with those on hemodialysis. This study compared the effects of icodextrin-based PD solutions on serum triglyceride and erythrocyte OA levels in PD patients.
Methods:In this multicenter, open-label, randomized crossover trial, 22 PD patients were enrolled, and 15 completed all study phases. Participants received either glucose- or icodextrin-based PD solutions for 12 weeks, followed by a 12-week washout period and crossover to the alternate solution. Blood and erythrocyte membrane samples were analyzed for lipid profiles and fatty acid composition.
Results:The mean age of participants was 63.6±9.5 years, and the mean PD duration was 10.8±5.9 months. Baseline characteristics were comparable between groups. Use of icodextrin-based PD solutions was associated with trends toward reductions in triglycerides (p=0.093) and erythrocyte membrane OA content, although these changes did not reach statistical significance. In contrast, prolonged use of glucose-based PD solutions led to significant increases in insulin (p<0.05), low-density lipoprotein cholesterol, OA (p=0.009), and monounsaturated fatty acid content.
Conclusions:Extended use of glucose-based PD solutions may worsen metabolic profiles, whereas icodextrin-based solutions may provide metabolic benefits. Larger, long-term studies are warranted to confirm these findings. (ClinicalTrials.gov Identifier: NCT02166359)
