  1. Autoantibodies against oxidized low-density lipoprotein in antiphospholipid syndrome.

    Article - En anglais

    The prevalence and clinical significance of anti-oxidized low-density lipoprotein antibodies (anti-ox-LDL) were evaluated in patients with the antiphospholipid syndrome (APS).

    Anti-ox-LDL were measured in the sera of 107 patients with APS (64 primary APS. 43 secondary to systemic lupus erythematosus) by enzyme-linked immunosorbent assay (ELISA) utilizing malondialdehyde (MDA) - modified LDL as antigen.

    In the same patients, anticardiolipin antibodies (aCL) and anti-/12-glycoprotein I antibodies (anti-bêta2GPI), were also measured.

    A positive titre of anti-ox-LDL was detected in 22% of patients, but only in 6% of control subjects (X2=12.


    Levels of anti-ox-LDL were higher in patients with arterial thrombosis (n=58) than in those without (n=49) (P=0.0001).

    Anti-ox-LDL levels correlated weakly with those of aCL (r=0.196, P=0.043). but not with those of anti-bêta2GPI (r=0.076).

    Our findings suggest that elevated levels of anti-ox-LDL may represent another potential marker of APS, particularly of patients prone to arterial thrombosis.
