Ankylosing spondylitis (AS) is a chronic inflammatory disease associated with increased risk of cardiovascular disease (CVD). A recent study found that HDL from patients with AS displays impaired antiatherogenic properties. Attenuation of such HDL properties may constitute a link between AS and CVD.

Method

  • HDL (apoB-depleted serum) was isolated from 35 patients with AS and 35 age- and sex-matched controls
  • Measurements: antioxidant capacity of HDL, ability of HDL to induce cholesterol efflux, activity of HDL-associated enzymes paraoxonase-1 (PON1) and myeloperoxidase (MPO), the ability of HDL to induce Akt kinase activation

Results

  • HDL from patients ...
