Association between dyslipidemia and residual renal function in patients on chronic peritoneal dialysis
1Department of Internal Medicine, Division of Nephrology, Far Eastern Memorial Hospital, Tapei, Taiwan.
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.

One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
