Study Visceral Adipose Tissue and Liver Stifness in a Retrospective Cohort of Diabetes Mellitus Patients

Central Hospital, Nancy, France86 enrolled

Overview

Non Alcoholic Fatty Liver Disease (NAFLD) is an emergent disease worldwide, and soon the leading cause of hepatic transplant in the USA. Among this high number of patients, the current challenge is to detect or even predict patients at risk of inflammation (Non Alcoholic or Steatohepatitis or NASH) and end-stage fibrosis, which are the best predictors of liver-related mortality. Visceral obesity is intimately associated with metabolic disease and adverse health outcomes, such as diabetes, and NAFLD. It has been demonstrated that visceral adipose tissue-linked inflammation was a risk factor of stroke, myocardial infarction, and others metabolic-related complications. The aim of this study was to evaluate the association of the quantity and percentage of Visceral Adipose Tissue by Dual X-Ray Absorptiometry and liver stiffness by Fibroscan in patients with type 2 diabetes, and other predictors of fibrosis such as FIB-4 and Fibrotest. We retrospectively collected the data of all the diabetic patients who had undergone a DEXA and a Fibroscan between January 1st, 2014 and Decembre 31th, 2019, in the Universitary Hospital of Nancy, France.
