暂无%X Objective To observe the expression of anti-β2 glycoprotein I (β2GPI) autoantibody in connective tissue diseases and its relationship with the degree of inflammation and immune function. Methods Patients with broad connective tissue diseases including connective tissue disease (CTD), rheumatoid arthritis (RA), Sjogren's syndrome (SS), and systemic lupus erythematosus (SLE) were observed. β2GPI was quantified by chemiluminescence, ESR was measured by Weil's method, and C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated polypeptide (CCP) antibody were measured by automatic biochemical analyzer. Results β2GPI and their subtypes were significantly higher in RA patients compared with CTD, SS, and SLE patients. CRP was positively associated with anti-β2GPI antibody and anti-β2GPI antibody IgM in patients with connective tissue disease. ESR was positively associated with anti-β2GPI antibody. Anti-β2GPI antibody and anti-β2GPI antibody IgM were elevated in the abnormal CRP group compared with the normal CRP group. Compared with the ESR normal group, anti-β2GPI antibody and anti-β2GPI antibody IgG were elevated in the ESR abnormal group. Anti-β2GPI antibody was positively correlated with ESR and anti-CCP antibody in RA patients. Anti-β2GPI antibody IgG was positively correlated with RF. Conclusion β2GPI can be used as a predictor of the degree of inflammation and assessment of immune disorders in CTD.
