Do antibodies to beta2-glycoprotein 1 contribute to the better characterization of the antiphospholipid syndrome?

Description
Summary:The aim of this study was to determine if the measurement of anti-beta2-glycoprotein I antibodies (abeta2-GPI) in serum levels contributes to the better characterization of the clinical situation of patients with antiphospholipid syndrome (APS). For this purpose abeta2-GPI of both isotypes was measured in 42 patients with APS and 32 SLE patients without APS. Clinical records of all patients were thoroughly reviewed. The presence of abeta2-GPI was correlated with the clinical manifestations of APS and compared with the presence of anticardiolipin antibodies (aCL) and lupus anticoagulant (LA) activity. There was a positive correlation between levels of aCL and abeta2-GPI for both IgG and IgM isotypes (rho of Spearman=0.82 and 0. 64 respectively, P=0.0001). Both antibodies presented significantly higher titres in LA positive patients (P
