Abstract

Objective: To test the prevalences and the clinical associations of anticardiolipin (aCL) and anti-β₂GPI (aβ₂GPI) antibodies in a large series of European patients with systemic lupus erythematosus (SLE). Methods: 574 SLE patients from 7 European countries were tested for aCL and aβ₂GPI by ELISA methods. Results: aCL of IgG, IgM, and IgA isotypes were detected in 22.8%, 14%, and 13.9% of the patients, respectively. IgG and IgM aβ₂GPI were detected in 20% of the patients. The presence of aCL was highly associated with the presence of aβ₂GPI. Medium-high titer IgG aCL and aβ₂GPI were associated with thrombosis, with similar sensitivity, specificity, and positive predictive value. When present at medium-high titer, IgG aCL were associated with thrombocytopenia, IgM aCL with hemolytic anemia, and cerebrovascular accidents, IgA aCL with livedo reticularis and Raynaud's phenomenon. Conclusions: aCL, when present at medium-high titer, are as important as aβ₂GPI, as a risk factor for thrombosis. Medium-high titer aCL, but not aβ₂GPI, are associated with other clinical features of the antiphospholipid syndrome.
