AI Article Synopsis

  • Non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes (T2D) share similar metabolic issues, particularly insulin resistance and metabolic alterations.
  • Research shows that some glucose-lowering medications help with both conditions, but effectiveness varies, and the reasons why some work better for NAFLD are still debated.
  • It's suggested that improving the metabolism of free fatty acids might be crucial for treating NAFLD, indicating that certain medications could target this issue effectively.

Article Abstract

Non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes (T2D) are metabolic disorders connected by common pathophysiological mechanisms. Since insulin resistance (IR) and metabolic alterations are common to both conditions, almost all glucose-lowering agents which improve IR have also been studied in patients with NAFLD. Some have shown great efficacy, others none. Thus, the mechanisms behind the efficacy of these drugs in improving hepatic steatosis, steatohepatitis, and eventually fibrosis remain controversial. Glycaemic control improves T2D, but probably has limited effects on NAFLD, as all glucose-lowering agents ameliorate glucose control but only a few improve NAFLD features. In contrast, drugs that either improve adipose tissue function, reduce lipid ingestion, or increase lipid oxidation are particularly effective in NAFLD. We therefore hypothesise that improved free fatty acid metabolism may be the unifying mechanism behind the efficacy of some glucose-lowering agents on NAFLD and may represent the key to NAFLD treatment.

Glucose-Lowering Agents Developed in the Last Two Decades and Their Perioperative Implications.

The last two decades have provided far more options f both patients and their physicians in the treatment of diabetes mellitus. While dipeptidyl peptidase-4 inhibitors (DPP-4is) and glucagon-like peptide 1 receptor agonists (GLP-1RAs) have been approved for nearly two decades, sodium-glucose cotransporter 2 inhibitors (SGLT-2is) are relatively new. Of interest to perioperative physicians, these drugs present specific perioperative concerns, prompting many societies to issue guidelines.

Finerenone and new-onset diabetes in heart failure: a prespecified analysis of the FINEARTS-HF trial.

Lancet Diabetes Endocrinol

January 2025

British Heart Foundation Cardiovascular Research Centre, University of Glasgow, Glasgow, UK. Electronic address:

Background: Data on the effect of mineralocorticoid receptor antagonist therapy on HbA levels and new-onset diabetes are conflicting. We aimed to examine the effect of oral finerenone, compared with placebo, on incident diabetes in the Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients with Heart Failure (FINEARTS-HF) trial.

Methods: In this randomised, double-blind, placebo-controlled trial, 6001 participants with heart failure with New York Heart Association functional class II-IV, left ventricular ejection fraction 40% or higher, evidence of structural heart disease, and elevated N-terminal pro-B-type natriuretic peptide levels were randomly assigned to finerenone or placebo, administered orally.

Heart failure (HF) is a life-threatening condition with severe incapacitating consequences. Many body organs and systems may be affected, which may also hinder the quality of life and finances at the individual and societal levels. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have also emerged as potentially useful drugs in the HF domain and other medical fields, in addition to their glucose-lowering effect.
