Al suggests a strong relationship between increased serum dipeptidyl peptidase-4 (sDPP-4) in T2DM and the severity of hepatic fibrosis evaluated by liver span measurement (LSM) and Fibroscan-AST score (FAST score) measured by transient elastography18 indicating another possible explanation for the findings of our study. This evidence concerns the gene DPP4 and Hepatic fibrosis.
