Objective To investigate the significance of antibody to Ro-52 in patients with autoim-mune liver disease(AILD). Methods One hundred and fifteen patients with abnormal liver functions, who had anti-Ro-52 detection by immunological blotting, were reviewed retrospectively. According to types of AILD, the clinical features were compared between patients with and without anti-Ro-52, respectively, κ test of concordance was used to provide a chance-corrected valve for immune-serological results. Results The rates of anti-Ro-52 in autoimmune hepatitis( AIH), primary sclerosing cholangitis(PBC) and AIH/PBC o-verlap syndrome groups were 32.43%, 24.56% and 33.33%, respectively, there were no significant differ-enees among three groups ( x2 = 0. 949, P >0. 05). The rate of anti-soluble hver antigen/liver-pancreas ( an-ti-SLA/LP) in AIH patients with anti-Ro-52 (58.33%) was higher than AIH patients without anti-Ro-52 ( 16.00% ,P < 0.05 ). The rate of anti-SLA/LP in AIH/PBC overlap syndrome patients with anti-Ro-52 (85.71%) was also higher than that of control group (28.57% ,P <0.05). Anti-Ro-52 and anti-SLA/LP had concordance according to κ test( κ >0.40, P <0.05). The average level of IgG in AIH/PBC overlap syndrome patients with anti-Ro-52 was higher than patients without anti-Ro-52 ( t = 2. 508, P < 0.05 ). Conclusion The rates of anti-Ro-52 in AIH, PBC and AIH/PBC overlap syndrome were of no significant differences. Anti-Ro-52 may have correlation with anti-SLA/LP. AIH/PBC overlap syndrome patients with anti-Ro-52 shewed higher IgG level than patients without anti-Ro-52.
