Due to genetic defects in apical membrane chloride channels, the cystic fibrosis (CF) intestine does not secrete chloride normally. Depressed chloride secretion leaves CF intestinal absorptive processes unopposed, which results in net fluid hyperabso

Quantitation of fecal bile acid excretion can help elucidate the cause of diarrhea or steatorrhea. Fecal bile acids can be measured with gas chromatography-mass spectrometry, but this is time-consuming, expensive, and not available for clinical use.

Background: Patients with short bowel syndrome (SBS) have steatorrhea, in part because of bile acid malabsorption that causes decreased bile acid secretion into the duodenum and consequent fat maldigestion. In SBS patients with colon in continuity, l

Background: We hypothesized that part of the non-specific antidiarrhoeal effect of octreotide is mediated by a proabsorptive or antisecretory effect on small intestinal active electrolyte transport. Methods: To measure the effect of octreotide on net

Previous studies in rats showed that the administration of recombinant human growth hormone markedly increased intestinal absorption of electrolytes and water and suggested that growth hormone would be a useful antidiarrheal agent. We therefore exami

Hyperkalemia in patients with renal failure is frequently treated with a cation exchange resin (sodium polystyrene sulfonate, hereafter referred to as resin) in combination with a cathartic, but the effect of such therapy on serum potassium concentra

Because there are no published reference values for fecal phosphate concentration or output, diagnosing surreptitious use of phosphate laxatives has been difficult. The purposes of this study were to determine normal fecal phosphate levels and to qua

In people with constipation, it is not known if decreased frequency of defecation is associated with abnormalities in the weight or in the consistency of stools or if the weight or the consistency of stools correlates with the severity of various dis

BACKGROUND & AIMS: Net sodium absorption from oral rehydration solution is increased by both glucose-sodium cotransport and solvent drag. The aim of this study was to measure the relative importance of glucose- sodium cotransport and solvent drag in

In 1945 Gamble et al.1 and Darrow2 reported on two infants with severe congenital diarrhea, in back-to-back articles with identical titles. Both infants had very high stool chloride concentrations, low urinary chloride excretion, hypochloremia, metab
