Summary
Alpha-1-antitrypsin is a 52 kD glycoprotein produced in the liver, intestinal macrophages, monocytes and intestinal epithelial cells. It belongs to the group of acute-phase proteins and is one of the most important proteinase inhibitors in
serum. Alpha-1-antitrypsin inhibits the proteinases trypsin and neutrophil elastase (1). A deficiency leads to increased proteolysis. Since alpha-1-antitrypsin is not appreciably broken down or resorbed in the intestine, it can be detected in the stool if the intestinal mucosa has increased permeability (“leaky gut” syndrome) (1,2).
Patients with inflammatory bowel disease show elevated levels of alpha-1-antitrypsin in their stools (4).
Taking non-steroidal anti-inflammatory drugs (e.g. aspirin, ibuprofen, diclofenac) or COX-2 inhibitors (e.g. celecoxib) can lead to enteropathies, which result in an increase in the alpha-1-antitrypsin value in the stool. Before carrying out the
determination, the corresponding medication should therefore not be taken for a period of 14 days, so as not to influence the measurement of the degree of intestinal inflammation.
In the case of diarrhea, due to the dilution effect, normal values can be measured in the stool despite the presence of inflammatory processes in the intestine.
