Prevalence of Clinically Significant Liver Fibrosis as Measured by Transient Elastography due to Non-alcoholic Fatty Liver Disease in Indian Individuals with Type 2 Diabetes Mellitus

Abstract

Abstract Introduction: There is high prevalence of non-alcoholic fatty liver disease in individuals with type 2 diabetes mellitus (T2D), and available evidence suggests higher prevalence of NASH and advanced stages of fibrosis among T2D. Data regarding prevalence of clinically significant liver fibrosis (CSLF) in individuals with T2D is scarce. We investigated the prevalence of transient elastography (TE)-proven CSLF among patients of T2D attending a diabetes clinic at a tertiary care center. Methods: A cross-sectional descriptive evaluation study of 603 consecutive adults with T2D was conducted to detect CSLF using TE. Steatosis was diagnosed using a controlled attenuation parameter >237 dB/m. Results: The prevalence of CSLF was 22.7%, and the prevalence of steatosis was 58.9% in our study. A higher body mass index (BMI) (P = 0.001), aspartate aminotransferase (AST; P = 0.0001), alanine aminotransferase (ALT; P = 0.0001), and low platelets (P = 0.0001) were independent factors associated with CSLF. Elevated ALT and AST (≥40 units/L) levels were present in only 27.7% and 37.2% of individuals with CSLF, respectively. Twenty-six (4.31%) individuals had LSM > 13.0 kPa. Conclusion: CSLF is highly prevalent in T2D patients attending a diabetes clinic at a tertiary care center, and the majority of such individuals have normal transaminase levels. Higher BMI, AST, and ALT values and lower platelet counts are associated with liver fibrosis.
