The 75-SeHCAT test has been used for identifying, within a group of patients with chronic functional diarrhea, a subgroup of cases with ileal bile acid malabsorption. Thirty-four subjects were studied: 10 healthy subjects and 24 patients with chronic functional diarrhea. Findings are expressed as
The objective of the study was to investigate how taurine alleviates mucosal injury. Young chickens were fed with taurine for 1 week and then challenged with lipopolysaccharide. We found that, under lipopolysaccharide challenge, taurine could attenuate diarrhea and mucosal inflammation.
OBJECTIVE
Irritable bowel syndrome is a gastrointestinal disorder which can influence human metabolism. It has been demonstrated that probiotics are beneficial in controlling IBS. Thus, the main objective of the present study was to determine metabolic changes in response to diarrhea predominant
Fructus Gardenia (FG) is a widely used bitter and cold herb for clearing heat and detoxicating. Currently, toxicity of FG and its relative formula has been reported in many clinical and animal studies. However, no systematic research has been carried out on FG-related gastrointestinal Chronic diarrhea affects about 5% of the population overall. Altered bile acid metabolism is a common but frequently undiagnosed cause.We performed a systematic search of publication databases for studies of assessment and management of bile acid diarrhea When first described in 1976, primary bile acid diarrhea (BAD Type 1) was regarded as a very rare cause of chronic diarrhea. Today, the incidence is estimated as > 1 %. Availability of diagnostic tools varies widely and, in Germany, there is no generally consented recommendation for their use.
Bile acid diarrhea (BAD) is common with ileal resection, Crohn's disease, and diarrhea-predominant irritable bowel syndrome. Here, we demonstrate the efficacy of cystic fibrosis transmembrane conductance regulator (CFTR) inhibitor (R)-benzopyrimido-pyrrolo-oxazine-dione-27 (BPO-27) in
OBJECTIVE
Increased colonic bile acids can cause chronic diarrhea. Bile acid diarrhea (BAD) is treatable by sequestrants, and may be secondary to ileal disease or primary BAD. It is underdiagnosed, partly because the selenium-75-homocholic acid taurine (SeHCAT) retention test is not available in
The recommended reference values for the selenium-75-homocholic acid taurine (75SeHCAT) test, used in the analysis of chronic diarrhea, were evaluated in 211 patients by comparing simultaneous measurements of 3 alpha-hydroxy bile acids and 75Se activity in daily collected stools. An initial
OBJECTIVE
Chronic diarrhea of unknown origin is often associated with bile acid malabsorption, the pathogenetic role of which is uncertain. The aim of this study was to identify morphological abnormalities in the ileal and colonic mucosa in patients with this disorder.
METHODS
We performed a
Aquaporin (AQP) 3, which is predominantly expressed in the colon, is considered to play an important role in regulating the fecal water content in the colon. In this study, the role of AQP3 in the colon was examined using HgCl(2) and CuSO(4), which are known to inhibit AQP3 function. The fecal water
OBJECTIVE
Patients with bile acid diarrhea (BAD) are identified based on increased levels of BAs in fecal samples collected over a 48-hr period while on a 100-gram fat diet (48-hr BA), retention of 75Se-labeled homocholic acid taurine, or serum levels of C4 or FGF19. BAD increases fecal weight and
OBJECTIVE
Primary (idiopathic) bile acid malabsorption (BAM) is a common, yet underrecognized, chronic diarrheal syndrome. Diagnosis is difficult without selenium homocholic acid taurine (SeHCAT) testing. The diarrhea results from excess colonic bile acids, but the pathogenesis is unclear.
BACKGROUND
Bile acid malabsorption (BAM) is a recognized cause of watery diarrhea, often diagnosed empirically based on clinical response to cholestyramine. The radionuclide selenium-labelled homocholic acid-taurine whole body retention test is expensive, labour intensive and of limited
OBJECTIVE
Chronic diarrhea caused by primary bile acid diarrhea (PBAD) is a common condition. We have previously shown PBAD is associated with low fasting serum levels of the ileal hormone, fibroblast growth factor 19 (FGF19). FGF19 is a negative regulator of hepatic bile acid synthesis and is
