Abstract
BACKGROUND: Dyslipidemia and residual renal function (RRF) have a significant impact on the cardiovascular mortality in dialysis patients, but their association in patients on chronic peritoneal dialysis (PD) has not been completely studied. METHODS: 170 PD patients were divided into 2 groups based on the RRF (Group I had no RRF and Group II had RRF >0 ml/min/1.73 m2 BSA). An observational, longitudinal study was performed to elucidate the dyslipidemic state in PD patients with different levels of RRF and the association of dyslipidemia and deterioration of RRF during 3 years. RESULTS: Patients' basic characteristics and lipid profiles at the initiation of study were similar between the groups. At the end of study, Group I patients had a lower T-CHO (p=0.001), LDL-C (p=0.018), HDL-C (p=0.05) and non-HDL-C (p=0.003) than Group II. There was a significant correlation between a change in HDL-C and the decline of RRF (r=0.177, p=0.048) and it was independent of PD duration and levels of highly sensitive C-reactive protein (r=0.233, p=0.04). CONCLUSION: Our results clearly demonstrate the different longitudinal changes of lipid profiles in PD patients with different RRF and an association between decline of HDL-C and deterioration of RRF.
