Change of serum autoimmune antibodies in autoimmune liver disease and correlation analysis / 重庆医学

ABSTRACT

Objective To investigate the dynamic changes of serum autoimmune antibodies before and during treatment in auto-immune liver disease(AILD)and to study their clinical application and the practical significance.Methods The indirect immunoin-fluorescence was used to measure serum anti-nuclear antibody(ANA)on admission and at different clinical treatment time (1,3,12, 24 months)in 64 cases of autoimmune hepatitis(AIH)and 57 cases of primary biliary cirrhosis(PBC).At the same time the immu-noblot analysis was adopted to detect the liver disease related antibodies (anti-AMA-M2 antibody,anti-Sp100 antibody,anti-gp210 antibody,anti-LKM-1 antibody,anti-LC-1 antibody and anti-SLA antibody).The correlation analysis was performed by combining with the detection results of the liver enzymology.Results The detection rate of serum ANA before treatment was 57.8% in the AIH patients and 61.4% in the PBC patients respectively,and the titer was mostly distributed in 1∶320 and 1∶640.During treat-ment,the positive rate and titer of serum ANA in the AILD patients had no obvious change with the disease condition relief(P>0.05);in the liver disease antibodies detection,only anti-AMA-M2 antibody,anti-Sp100 antibody and anti-gp210 antibody were de-tected in the PBC patients,and the detection rates were in turn 73.7%,17.5% and 26.3% respectively;6 items of antibody were detected to different extent in the AIH patients,but which was dominated by the specific detection of anti-LKM-1 antibody,anti-LC-1 antibody and anti-SLA antibody;the liver function indexes in the ALID patients were gradually recovered after 1,3,12,24 months treatment(P0.05).Conclusion The autoimmune antibodies detection plays a very important role in diagnosis and differential diagnosis of AILD,but which has no change with the disease condition relief,thus can not be used as the index of the clinical curative effect observation.
