Abstract: Objective The aim of this study was to explore diagnostic performance of shear wave elastography and aspartate aminotransferase/platelet ratio index (APRI) combination in predicting significant liver fibrosis (SLF) in patients with type 2 diabetes mellitus (T2DM) and non-alcoholic fatty liver disease (NAFLD). Methods 73 patients with T2DM and NAFLD were enrolled in our hospital between January 2021 and December 2023, and all underwent transient elastography (TE) to obtain liver stiffness measurement (LSM), underwent shear wave elastography to obtain Yang’s modulus, and routine blood detection for APRI. Receiver operating characteristic (ROC) curves were drawn for assess diagnostic efficacy, and the consistency between shear wave elastography and APRI combination, and LSM in the diagnosis of SLF was analyzed by Kappa test. Results SLF was found in 19 cases (26.0%) based on LSM>7.4 kPa; body mass index, percentage of concomitant renal injury, serum AST, ALT level, LSM, APRI and Yang’s modulus in patients with SLF were (30.7±2.8)kg/m2, 42.1%, (92.3±10.5)U/L, (120.5±9.6)U/L, (12.7±3.1)kPam (1.2±0.4) and (10.7±3.1)kPa, all much higher than [(25.2±2.4)kg/m2, 20.4%, (49.8±8.1)U/L, (47.8±7.3)U/L, (6.1±1.6)kPa, (0.8±0.3) and ((5.1±1.6))kPa, respectively, P<0.05] in patients without SLF; the ROC analysis showed that the AUC was 0.891, with sensitivity of 94.7% and specificity of 74.1%, when Yang’s modulus and APRI combination in predicting SLF in patients with T2DM and with underlying NAFLD, much superior to any parameters doing alone (P<0.05); Kappa value between shear wave elastography and APRI combination, and TE in the diagnosis of SLF was 0.563 (P<0.05), suggesting moderate result. Conclusion Shear wave elastography and APRI combination in predicting SLF in patients with T2DM and NAFLD is efficacious, which might guide clinicians for further management.
