Abstract: Objective To distinguish between DIAIH and DILI, a differential diagnosis model for drug-induced autoimmune hepatitis (DIAIH) and drug-induced liver injury (DILI) was established based on hepatic ultrasound hemodynamics and liver biochemical indicators. Methods A retrospective analysis was conducted on medical records of 82 cases of drug-induced liver injury (DILI) and 74 cases of drug-induced autoimmune hepatitis (DIAIH) admitted to the hospital from January 2020 to January 2023. The study aimed to analyze the differences in hepatic ultrasound hemodynamics and liver biochemical indicators between the DILI and DIAIH groups, identify factors influencing the onset of DIAIH, and establish a differentiation model for DILI and DIAIH. Results The portal vein blood flow velocity in DILI group was higher than that in DIAIH group, and the hepatic artery blood flow velocity and resistance index were lower than that in DIAIH group [DILI group: (22.31±3.19) cm/s, (40.23±6.47) cm/s, (0.71±0.13) cm/s, DIAIH group: (19.49±3.02) cm/s (46.91±7.15) cm/s, (0.79±0.12) cm/s] (P<0.05). The levels of total bilirubin, total bile acid, alkaline phosphatase (ALP), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT) and globulin in DILI group were lower than those in DIAIH group [DILI group (18.62) μmol/L, (7.56) μmol/L, (96.05) U/L, (206). 53) U/L, (112.35) U/L, (29.13) g/L, DIAIH group (26.01) μmol/L, (22.61) μmol/L, (129.52) U/L, (328.65) U/L, (199.34) U/L, (35.02) g/L, ] (P<0.05). Portal vein blood flow velocity, hepatic artery blood flow velocity, resistance index, total bilirubin, total bile acids, and ALT were identified as influencing factors for the occurrence of DIAIH (P<0.05). The receiver operating characteristic (ROC) curve analysis showed that the sensitivity of the column chart model in distinguishing DIAIH was 0.825 (95%CI: 0.741~0.952), the specificity was 0.798 (95%CI: 0.703~0.883), and the area under the curve was 0.827 (95%CI: 0.749~0.964). Conclusion There are differences in hepatic ultrasound hemodynamics and liver biochemical indicators between DILI and DIAIH patients. Constructing a differentiation model based on hepatic ultrasound hemodynamics and liver biochemical indicators could be used to assist in the diagnostic differentiation of DILI and DIAIH.
