Association between lipid profile and residual renal function in incident peritoneal dialysis patients.

Introduction: Residual renal function (RRF) is one of the most crucial factors in the management of peritoneal dialysis (PD). The aim of this study was to evaluate the association between lipid profile and preservation of RRF among incident PD patients.

Methods: This retrospective cohort study investigated 113 patients (male, 72%; age, 59 ± 14 years) who initiated PD between 2006 and 2017. We investigated the relationships between high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) at PD initiation and change in renal Kt/V during the first year after PD initiation.

Results: Alterations in renal Kt/V during the first year after PD initiation correlated negatively with HDL-C at PD initiation but not with LDL-C. On multivariate analysis, HDL-C at PD initiation was independently associated with a change in renal Kt/V during the first year after PD initiation.

Conclusion: These results suggest the importance of lipid management among incident PD patients for the preservation of RRF.
