BACKGROUND: The association between proprotein convertase subtilisin/kexin type 9 (PCSK9), a critical regulator of low-density lipoprotein (LDL) metabolism, and kidney function is a matter of debate. OBJECTIVE: We aimed to assess the association of circulating PCSK9 concentrations with both glomerular filtration rate (eGFR) and serum lipid parameters in nondiabetic patients with chronic kidney disease (CKD). METHODS: Fasting plasma PCSK9 concentrations were measured by ELISA in 94 nondiabetic non dialysis CKD (ND-CKD) patients not receiving statins, at different stages of CKD. RESULTS: Plasma PCSK9 levels were associated neither to eGFR (P =.770) nor to proteinuria (P =.888) at several stages of CKD. In addition, plasma PCSK9 levels did not vary significantly between the different CKD stages. Plasma PCSK9 concentrations were positively correlated with apolipoprotein B (r = 0.221; P = .03) and triglycerides (r = 0.211; P = .04) but not with total cholesterol, calculated LDL-cholesterol, HDL cholesterol, lipoprotein(a), or CRP. CONCLUSION: In a homogeneous population of nondiabetic subjects without lipid-lowering therapy, plasma PCSK9 concentrations are not associated to eGFR at several stages of CKD. These data suggest that kidney function per se does not impact significantly PCSK9 metabolism. (C) 2016 National Lipid Association. All rights reserved.
