Background and Aim
The recommendation in regard to screening for non‐alcoholic fatty liver disease (NAFLD) among type 2 diabetes mellitus (T2DM) patients differs in major guidelines. The aim of this paper was to study the prevalence of NALFD and advanced fibrosis among T2DM patients.
Methods
This is a cross‐sectional study of consecutive adult T2DM patients attending the Diabetes Clinic of a university hospital. Significant hepatic steatosis and advanced fibrosis was diagnosed based on transient elastography if the controlled attenuation parameter was ≥ 263 dB/m, and the liver stiffness measurement was ≥ 9.6 kPa using the M probe or ≥ 9.3 kPa using the XL probe, respectively. Patients with liver stiffness measurement ≥ 8 kPa were referred to the Gastroenterology and Hepatology Clinic for further assessment, including liver biopsy.
Results
The data of 557 patients were analyzed (mean age 61.4 ± 10.8 years, male 40.6%). The prevalence of NAFLD and advanced fibrosis based on transient elastography was 72.4% and 21.0%, respectively. On multivariate analysis, independent factors associated with NAFLD were central obesity (OR 4.856, 95% confidence interval [CI] 2.749–8.577, P = 0.006), serum triglyceride (OR 1.585, 95% CI 1.056–2.381, P = 0.026), and alanine aminotransferase levels (OR 1.047, 95% CI 1.025–1.070, P < 0.001) while advanced fibrosis was associated with serum high‐density lipoprotein cholesterol (OR 0.355, 95% CI 0.126–0.997, P = 0.049), alanine aminotransferase (OR 1.023, 95% CI 1.009–1.037, P = 0.001), γ‐glutamyltransferase (OR 1.005, 95% CI 1.001–1.008, P = 0.017), and platelet levels (OR 0.995, 95% CI 0.992–0.999, P = 0.010). Seventy‐one patients underwent liver biopsy. The majority had non‐alcoholic steatohepatitis (83.1%) and ≥ F1 fibrosis (87.3%) while advanced fibrosis was seen in 36.6%.
Conclusion
The prevalence of NAFLD and advanced fibrosis based on transient elastography is high among T2DM patients.
