Understanding the connection between obesity and liver inflammation

Investigating the Link Between Type 2 Immunity and NAFLD in Human Obesity- AIM 1

Mayo Clinic · NCT04232566

This study looks at how extra fat around the liver and inflammation in body fat affect liver health and insulin resistance in people with obesity, especially those having gastric bypass surgery.

What this trial studies

This observational study aims to investigate the relationship between inflammation in adipose tissue and the abnormal fat deposition around the liver in individuals with obesity. It focuses on how these factors influence liver function and insulin resistance, particularly in patients undergoing gastric bypass surgery. By analyzing data from participants with confirmed liver fibrosis, the study seeks to provide insights into the mechanisms linking obesity and liver health.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 30-70 with a BMI greater than 40 kg/m2 who are undergoing gastric bypass surgery.

Not a fit: Patients with autoimmune diseases, active cancer, or those who have a history of heavy alcohol use may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of liver-related complications in obese patients.

How similar studies have performed: Other studies have explored the relationship between obesity and liver health, but this specific approach focusing on adipose tissue inflammation is relatively novel.
