Anti-beta2-glycoprotein I autoantibodies and metabolic syndrome.

Background: The metabolic syndrome (MetS) is a proatherogenic entity. Autoantibodies to phospholipid cofactors such as beta2-glycoprotein I (beta2-gpI) can influence atheroma appearance. Previous studies confirmed an association of IgA anti-beta2-gpI antibodies with cerebral ischemia, myocardial infarction, peripheral artery disease and carotid disease.
