Abstract: Objective The aim of this study was to investigate the prevalence of serum autoantibody spectrums in patients with different liver diseases. Methods 92 patients with autoimmune liver diseases (ALD), including autoimmune hepatitis (AIH) in51 cases, primary biliary cholangitis (PBC) in 27 cases and primary sclerosing cholangitis (PSC) in 14 cases, chronic hepatitis B(CHB) in 61 cases and chronic hepatitis C (CHC) in 15 cases, nonalcoholic steatohepatitis (NASH) in 34 cases, drug-induced liver injury (DILI) in 27 cases and healthy persons in 68 cases were recruited in our hospital between March 2019 and March 2022, and serum autoimmune antibody spectrum was detected by immunoblotting. Results The positive rates of anti-mitochondrial antibody M2 subtype (AMA-M2), anti-soluble liver antigen/anti-liver pancreas antibody (SLA/LP), anti-liver kidney microsomal antibody type I (LKM-1), anti-transmembrane glycoprotein 210 (gp210), anti-liver cytosol antigen type I (LC-1), anti-3E, anti-promyelocytic leukemia (PML) and anti-RO-52 in patients with ALD 23.9%,13.0%,33.7%,19.6%,26.1%, 33.7%, 23.9% and 55.4%, significantly higher than in patients with other liver diseases (P<0.05); the positive rates of anti-SLA/LP, anti-LKM-1 and anti-LC-1 in patients with AIH were much higher than in patients with PBC or in patients with PSC(P<0.05), while the positive rates of AMA-M2, anti-gp210 and anti-3E in patients with PBC were much higher than in patients with AIH or in those with PSC(P<0.05); the positive rates of serum anti-LKM-1 and anti-LC-1 in 24 patients with AIH type Ⅱ were 100.0% and 66.7%, much higher than 19.0% and 19.0% (P<0.05) in 21 patients with AIH type Ⅰ or 16.7% and 33.3% (P<0.05) in 6 patients with AIH type Ⅲ, while the positive rate of serum anti-SLA/LP in patients with AIH type Ⅲ was 83.3%, much higher than 9.5% in patients with AIH type Ⅰ or 16.7% in patients with AIH type Ⅱ(P<0.05). Conclusion The detection of serum autoantibody spectrums is a key approach for the diagnosis and clinical classification of patients with ALD, and why they appear, though at low prevalence, in patients with other liver diseases needs further investigation.
