Excretion of bile acids in healthy children and children with cystic fibrosis. 1980

A Eklund, and A Norman, and B Strandvik

Urinary bile acid excretion was investigated in twenty-two patients with cystic fibrosis (CF) and in seven healthy children. CF patients with and without antibiotic treatment were compared. Bile acids were determined in 24-h samples after separation into unconjugated, glycine conjugated, taurine conjugated and sulphate conjugated bile acids. In total twenty bile acids were identified of which cholic, chenodeoxycholic, 3 beta-hydroxy-5-cholenoic acid and 24-nor-5 beta-cholan-23-oic acid were routinely present in samples collected from both CF patients and healthy children. None of the other bile acids were preferentially excreted by CF patients. When compared with the normal group, no statistical significance could be attached to the increased total urinary bile acids excreted by the CF patients (due to the large individual variations). The CF patients excreted increased amounts of cholic acid, 3 alpha, 7 beta, 12 alpha-and 3 beta, 7 beta, 12 alpha-trihydroxy-5 beta-cholanoic acids mainly in the unconjugated state. After administration of 24-[14C]cholic acid to thirteen CF patients the isotope excretion in faeces and urine was studied. Most of the patients had a high faecal excretion indicating great losses of bile acids from enterohepatic circulation. Compared to normal adults CF children excreted isotope in increased amounts in the urine.

D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D003550	Cystic Fibrosis	An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.

D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.

D001647	Bile Acids and Salts	Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones.	Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
