Abstract:
Objective To detect the value of autoantibedy profile in primary biliary cirrhosis (PBC). Methods 96 serum samples of patients with primiary biliary cirrhosis, 100 serum samples of other antoimmune disease and 49 serum samples of healthy were tested for anti- M2, anti-3E(BPO), anti-Sp100,anti-PML,anti-gp210,anti-LKM-1 ,anti-LC-1 ,anti-SLA/LP by EUROLine. Results The positive of the anti-M2,anti-BPO, anti-Sp100, anti-PML and anti-gp210 for PBC was 76. 0%, 84.4%, 32. 3%, 28. 1% and 35.4% ,respectively. The positive of the anti-M2, anti-BPO, anti-Sp100, anti-PML and anti-gp210 for other autoimmune disease was 13.0% ,9. 0% ,3.0% ,2.0% and 1. 0%, respectively. The sensitivity of the anti-M2 for PBC was 76. 0% ,with specificity of 87. 0%. The sensitivity of the anti-BPO for PBC was 84. 4%, with specificity of 91.0% ;the sensitivity of the anti-Sp100 for PBC was 32. 3%, with specificity of 97.0%. The sensitivity of the anti-PML for PBC was 28. 1% ,with specificity of 98.0%. The sensitivity of the anti-gp210 for PBC was 35.4%, with specificity of 99. 0% . Anti-LKM-1, anti-LC-1, anti-SLA/LP positive patients with PBC were not detected;the incidence rate of liver function failure in anti-gp210 positive serum higher than anti-gp210 negative serum (χ2 = 11.17, P < 0. 01). Conclusions Multiple autoantibedies can be detected in the sera of PBC patients. The detection of autoantibody profile is useful for the diagnosis and differential diagnosis of PBC, and may he helpful for therapy and prognosis of PBC.
