Abstract

To investigate the positive rate of auto antibodies and autoimmune liver diseases in patients with abnormal liver function and it's clinical significance. 511 sera with abnormal ALT (>40 U/L) were continuously collected, all the sera were examined for antibodies and clinical information of 469 cases were studied. Among the 511 sera, 14.09% of them showed of ANA positive, 0.59% of SMA positive, 2.94% of AMA positive, 0.98% of AMA-M2 positive, 0.59% of SS-A positive, 0.19% of SS-B positive, 0.19% of JO-1 and 0.78% of dsDNA positive and all SLA/LP, LC-1 and LKM-1 and ANA profile were negative. Clinical information was analyzed on 469 cases which have complete data from the 511 patients. Of these 469 cases, 5 cases (1.06%) were found to be PBC, 2 case (0.43%) were AIH, no PSC was found, 77.78% patients among those with positive auto antibodies were diagnosed as viral hepatitis and there were 18.29% patients with viral hepatitis showed different auto antibodies. The high titer auto antibodies were important criterion for diagnosis of autoimmune liver diseases. The positive rate of autoantibodies of autoimmune liver diseases was similar to hepatitis C and E
