Abstract
BACKGROUND
Hypoalbuminemia commonly observed in cirrhosis is considered to be mainly related to hepatocellular dysfunction. However, the correlation between the decrease in serum albumin and liver function is far from linear and arguments in favor of an additive role of protein-losing enteropathy have been brought by a few studies.
AIM
To assess the potential role of protein-losing enteropathy in a group of patients with cirrhosis, portal hypertension, and hypoalbuminemia.
DESIGN AND METHODS
Eleven patients with documented cirrhosis, portal hypertension, and a low serum albumin level compared to liver function underwent an (111)In-transferrin scintigraphy.
RESULTS
Using this sensitive method of investigation, nine exhibited features suggestive of exudative enteropathy. Serum albumin level and digestive protein loss were even correlated (Pearson's coefficient = -0.529, one-sided p = 0.047). Protein loss were however not correlated with the degree of portal hypertension or with the extent of liver dysfunction evaluated by the aminopyrine breath test.
CONCLUSIONS
Our preliminary data obtained in a small group of selected patients with cirrhosis, portal hypertension, and hypoalbuminemia indicate that protein-losing enteropathy may represent an appreciable and underestimated cause of hypoproteinemia.
