[Loss of inhibitors of the blood coagulation system in protein-losing enteropathy (author's transl)].

The investigation of the haemostasis of a 11 6/12 years old boy with protein-losing enteropathy revealed signs of hypercoagulability of the coagulation system, due to a decreased plasma concentration of antithrombin III and alpha1-antitrypsin, that were lost with other proteins in great amounts into the intestinal tract. The loss of these two important inhibitors of the coagulation system can lead to thrombotic complications in patients with protein losing enteropathy.
