We tried to evaluate the value of the alpha-1-antitrypsin clearance in order to search for the protein loss through the digestive tract. Twenty-two patients were studied, 11 with protein losing enteropathy and 11 normal controls. Alpha-1-antitrypsin concentration was determined in serum and feces to obtain the clearance of such protein. The values were always abnormal in patients with protein losing enteropathy, and normal in control patients. We consider this method simple and safe for the evaluation of intestinal protein loss, besides having the advantage of not using radioactive material.

D011504 Protein-Losing Enteropathies Pathological conditions in the INTESTINES that are characterized by the gastrointestinal loss of serum proteins, including SERUM ALBUMIN; IMMUNOGLOBULINS; and at times LYMPHOCYTES. Severe condition can result in HYPOGAMMAGLOBULINEMIA or LYMPHOPENIA. Protein-losing enteropathies are associated with a number of diseases including INTESTINAL LYMPHANGIECTASIS; WHIPPLE'S DISEASE; and NEOPLASMS of the SMALL INTESTINE.
