Abstract

BACKGROUND:

Numbers of drugs are required to manage patients with chronic kidney disease (CKD). Drug adherence is relatively poor in this population.

METHODS:

In 36 CKD patients with hypertension and dyslipidemia, who were prescribing amlodipine 5 mg and atorvastatin 10 mg daily, the influences of exchanging to a combination drug containing equivalent doses of amlodipine and atorvastatin were observed for 6 months.

RESULTS:

At the baseline, flow-mediated dilation (FMD) was reduced (2.4 ± 0.3%), and proteinuria was significantly contributed to decrements of FMD (R (2) = 0.38, F = 3.7, df (6,29), and  P < 0.01). Six months later from exchanging to combination drug, total cholesterol (TC, 197 ± 5 to 183 ± 3 mg/dL,  P < 0.01) and triglycerides (142 ± 14 to 129 ± 10 mg/dL, P < 0.05) were decreased, but high density lipoprotein cholesterol (53 ± 3 to 56 ± 3 mg/dL, P < 0.05) was increased. FMD was slightly albeit significantly improved to 2.7 ± 0.3% (P < 0.05). No serious adverse effects were seen by the combination drug. Subanalysis for the patients with considerable reductions of TC demonstrated that the combination drug decreased proteinuria and high sensitive CRP (P < 0.05 for both).

CONCLUSION:

Our data indicate that proteinuria constitutes a determinant of a reduced FMD. The present results implicate that combination drug is useful to improve adherence and suggest that atorvastatin refines endothelium function as well as lipid profiles in CKD patients.
