Abstract: Objective The aim of this study was conducted to compare the clinical features of patients with drug-induced autoimmune hepatitis (DI-AIH), autoimmune hepatitis (AIH) and drug-induced liver injury (DILI). Methods 22 patients with DI-AIH, 23 patients with DILI and 23 patients with AIH were encountered in our hospital between January 2017 and December 2021, the patients with AIH and DI-AIH were treated with prednisone and/or azathioprine combination therapy, and those with DILI were dealt with liver-protecting medicines. All patients were followed-up for two years. Results The percentages of definite medicine administered before diagnosis of patients with DILI and DI-AIH were 82.6% and 100.0%, with the alleged Chinese herbal medicine mainly, both significantly higher than 17.4%(P<0.05) in patients with AIH; the incidence of common symptoms, such as anorexia, jaundice and diarrhea in patients with DI-AIH was 81.8%, much higher than 52.2% and 47.8% (P<0.05) in those with AIH or with DILI; serum alanine aminotransaminase, alkaline phosphatase, glutamine transpeptidase and total bile acid levels in patients with DI-AIH were 331.2(116.4, 512.5) U/L, 125.4(91.6, 164.8) U/L, 202.4(98.8, 394.1) U/L and 23.7(13.1, 69.7)μmol/L, all significantly higher than [198.6(94.3, 497.6)U/L, 98.9(67.7, 168.9)U/L, 101.2(49.6, 231.4)U/L and 7.1(2.7, 29.2)μmol/L, respectively, P<0.05] in patients with DILI or [86.7(32.4, 186.3)U/L, 65.8(54.7, 109.8)U/L, 71.6(61.4, 142.5)U/L and 11.5(4.1, 35.6)μmol/L, respectively, P<0.05] in patients with AIH, while serum globulin level in patients with AIH was 35.6(28.7, 41.4) g/L, significantly higher than 28.8(21.2, 34.5) g/L in patients with DILI (P<0.05) or 30.5(24.6, 42.1)g/L in patients with DI-AIH (P<0.05); there were no significant differences as respect to peripheral white blood cell counts among the three groups (P>0.05). Conclusion The main pathogenic medicines in patients with DILI and DI-AIH are Chinese herbal medicine, and the clinical features of patients with DI-AIH are unique, presenting with highly increased serum biochemical parameters and good prognosis, showing response to immunosuppression and liver-protecting therapy.
