Overexpression of Hepassocin in Diabetic Patients with Nonalcoholic Fatty Liver Disease May Facilitate Increased Hepatic Lipid Accumulation

Abstract

Background & aims: Insulin resistance is the real determinant of both Nonalcoholic fatty liver disease (NAFLD) and diabetes, and can facilitate the accumulation of triglycerides in the liver. Overexpression of hepassocin (HPS) increased the accumulation of hepatic fat and NAFLD activity scores (NAS) in mice. The aim of this study was to investigate the relationship between hepassocin and steatosis of the liver in diabetic patients with or without NAFLD in humans.

Methods: The study enrolled 60 patients plus 20 healthy controls that were divided into 4 groups: Group I: included 20 patients who were diagnosed as diabetes mellitus type 2, Group II: included 20 patients who were diagnosed as nonalcoholic fatty liver disease (NAFLD), Group III: included 20 patients who were diagnosed as diabetes type 2 and NAFLD, and Group IV (control group): included 20 healthy person or controls who were matched in age and sex with patients group. All patients and controls were subjected to full history taking, thorough clinical examination, laboratory investigations including measurement of serum hepassocin in peripheral blood by ELISA technique.

Results: There was a significant overexpression of serum hepassocin in patients with type 2 diabetes and NAFLD patients (Group 3) more than diabetic patients (Group 1) and even more than non-alcoholic fatty liver disease (Group 2).

Conclusion: This study provides evidence that increased HPS may facilitate increased hepatic lipid accumulation with NAFLD and type 2 diabetes.
