Intestinal permeability in liver cirrhosis

Area of Science:

• Gastroenterology
• Hepatology
• Internal Medicine

Background:

• Liver cirrhosis is associated with various complications, including alterations in gastrointestinal function.
• Intestinal permeability is a crucial factor in maintaining gut barrier integrity and preventing translocation of bacteria.
• Understanding changes in intestinal permeability in cirrhosis is vital for managing complications like spontaneous bacterial peritonitis (SBP).

Purpose of the Study:

• To quantify changes in intestinal permeability in patients diagnosed with liver cirrhosis.
• To explore the correlation between intestinal permeability and the stage and etiology of cirrhosis.
• To investigate the relationship between intestinal permeability and the occurrence of spontaneous bacterial peritonitis (SBP).

Main Methods:

• A prospective study involving 44 liver cirrhosis patients and 10 healthy controls.
• Intestinal permeability was assessed by measuring 24-hour urine excretion of 99mTc DTPA (diethyl triamine penta-acetic acid).
• Exclusion criteria included associated diseases, impaired renal function, ongoing alcohol consumption, and medications affecting intestinal permeability.

Main Results:

• Cirrhotic patients exhibited significantly higher 24-hour 99mTc DTPA urine excretion compared to healthy controls (P < 0.0001).
• No significant relationship was found between intestinal permeability and the Child-Pugh grade or etiology (alcoholic vs. non-alcoholic) of cirrhosis.
• There was no significant difference in 99mTc DTPA excretion between cirrhotic patients with and without SBP.

Conclusions:

• Intestinal permeability is demonstrably increased in patients with liver cirrhosis.
• This increase in intestinal permeability is consistent across different stages and etiologies of cirrhosis.
• The findings suggest that increased intestinal permeability is not a primary factor in the development of SBP in cirrhotic patients.
