Abstract
Background. Type 2 diabetes mellitus (T2DM) is a major risk factor for the development of non-alcoholic fatty liver disease (NAFLD) and subsequently hepatic fibrosis. Transient elastography (TE) is a rapid, reproducible non-invasive test that may be appropriate as a screening tool for the presence of hepatic fibrosis. AIM: Assess the utility of TE as a screening tool for the presence of hepatic fibrosis in a T2DM population with no known liver disease. Methods. T2DM patients without known liver disease were included. Patients were assessed with TE in addition to biochemical parameters. Results. A successful TE evaluation could be obtained in 74 of 81 (91%) included subjects. Of these, 26 (35%) had a liver stiffness measurement (LSM) ≥7.65 kPa. Sixteen of these subjects had confirmatory liver biopsies with significant (≥F2 fibrosis) present in 12 (75%) and cirrhosis diagnosed in 2 subjects. 15/16 (94%) had histological steatohepatitis. Compared with those with a lower LSM, subjects with an LSM ≥ 7.65 kPa had higher ALT levels (38.0 ± 21.7 vs 26.1 ± 11.1 U/L, p = 0.021) and increased prevalence of hepatic steatosis by ultrasound (85% vs 63%, p = 0.005). Conclusion. Significant hepatic fibrosis in the T2DM population is frequently under-recognized. TE may be a feasible tool for the screening of T2DM patients for the presence of hepatic fibrosis.
