Paraoxonase-3 is depleted from the high-density lipoproteins of autoimmune disease patients with subclinical atherosclerosis.

ABSTRACT: Patients with autoimmune diseases have a significantly increased risk of developing cardiovascular disease. In disease, high-density lipoprotein (HDL) particles lose their anti-inflammatory and antioxidant properties and become dysfunctional. The purpose of this study was to test the hypothesis that alterations in the HDL proteomic profile are associated with subclinical atherosclerosis and HDL dysfunction in patients with autoimmune diseases such as systemic lupus erythematosus (SLE) and type 1 diabetes. Targeted proteomics was used to quantify the relative abundance of 18 proteins in HDL from SLE patients with and without atherosclerotic plaque detectable by carotid ultrasound. Changes in the proteomic profile were compared against the in vitro ability of HDL to protect against lipid oxi
