Examining malnutrition mechanisms in cirrhosis patients

Mechanisms of Malnutrition in Cirrhosis With Portosystemic Shunting

The Cleveland Clinic · NCT03121404

This study is trying to understand how malnutrition happens in people with cirrhosis by looking at muscle and fat loss, and comparing them to healthy individuals.

What this trial studies

This observational study investigates the mechanisms of malnutrition in patients with cirrhosis, particularly focusing on the role of myostatin in muscle and fat mass loss. It will compare 16 cirrhotic patients undergoing liver transplantation with 16 healthy controls undergoing elective abdominal surgery. Nutritional assessments will include anthropometry, dual energy x-ray absorptiometry (DEXA), and bioelectrical impedance analysis (BIA), alongside rectus abdominis muscle biopsies to analyze myostatin expression and related signaling pathways. The goal is to better understand how malnutrition develops in cirrhosis and its implications for patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-70 with cirrhosis undergoing liver transplantation or other abdominal surgeries.

Not a fit: Patients with chronic diseases causing cachexia, active intravenous drug users, or those with significant alcohol intake may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved nutritional management strategies for cirrhotic patients, potentially enhancing their outcomes before and after liver transplantation.

How similar studies have performed: While the specific mechanisms of myostatin in cirrhosis are less explored, similar studies have shown promising results in understanding malnutrition in other chronic conditions.
