Abstract:
Objective This study has explored the role of antibody against annexin A2 in patients with antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE). Methods Using purified recombinant annexin A2, IgG anti-annexin A2 antibody was measured by ELISA in 101 APS patients, 41 SLE patients with thrombosis, 124 SLE patients without thrombosis and 120 healthy controls. Results The positive rate of IgG anti-annexin A2 antibody in APS patients and SLE patients with thrombosis was 21.8%, 26.8%, respectively, they were all significantly higher than in SLE patients without thrombosis (6.5%). IgG anti-annexin A2 antibody was associated with thrombosis and/or pregnancy morbidity (P<0.01). Conclusion Anti-annexin A2 antibody is associated with thrombosis and/or pregnancy mnrbidity. It suggests that anti-annexin A2 antibody may be helpful in identifying in some potential AIRS.
