[Performance and clinical usefulness of the 14CO2-glycocholate-breath-test]. 1977

W Pancho, and J Adlung

14C-glycocholate breath-tests were performed in 22 clinical patients without gastointestinal disorders, in 11 cases with M. Crohn of the ileum and in 8 patients, in whom an intestinal overgrowth with bacteria was suspected. Additional to the usual discontinuous measurement of the specific activity of 14CO2 the exhaled amount of CO2 and 14CO2 and 14C-serum activity were determined. No advantage was found in the determination of the latter; for 1. discontinuous measurement of the specific activity of 14CO2 was sufficient for detecting disturbed enterohepatic bile-salt circulation; and 2. measurement of 14C-serum-activity or 14C-activity in cholic acids or protein were of no help in differentiating between bacterial overgrowth and diseases of the ileum. There remained doubts regarding the clinical usefulness of the test. Low specificity and many positive tests in patients without corresponding symptoms require that therapeutical procedures in such patients are initiated with some reserve.

D002793	Cholic Acids	The 3 alpha,7 alpha,12 alpha-trihydroxy-5 beta-cholanic acid family of bile acids in man, usually conjugated with glycine or taurine. They act as detergents to solubilize fats for intestinal absorption, are reabsorbed by the small intestine, and are used as cholagogues and choleretics.	Cholalic Acids,Acids, Cholalic,Acids, Cholic
D003424	Crohn Disease	A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental. Epithelioid GRANULOMAS may be seen in some patients.
