Abstract

The antiphospholipid syndrome (APS) with its typical clinical manifestations of recurrent thrombosis and fetal loss is biochemically defined by the presence of circulating antiphospholipid antibodies (aPL). The disease pattern has raised special interest as a possible link between autoimmunity and atherosclerosis. aPL, oxidized low density lipoproteins (oxLDL), and antibodies to oxLDL (Anti-oxLDL) are suggested to play an important role in atherogenesis. In the present study we compared the serum levels of oxLDL and Anti-oxLDL in APS patients (20 subjects with primary APS; 14 subjects with secondary APS) and nonAPS subjects (24 phenotypically healthy controls samples and 12 patients with systemic lupus erythematosus [SLE]) and investigated associations of the above mentioned parameters with the intima-media thickness (IMT), a clinical surrogate parameter of atherosclerosis.SLE patients with and without APS showed significantly increased levels of Anti-oxLDL as compared to the controls group (p = 0.038 and p = 0.007, respectively). In contrast, oxLDL levels were not significantly different between the controls group and patients. The Anti-oxLDL levels correlated significantly with anticardiolipin (p = 0.002) and beta(2)-glycopro...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
