Filter by:The study is designed to observe the use of a peptide-based oral nutrition supplement in adults with chronic malabsorption or maldigestion who require supplemental nutrition as assessed by a clinician.
Compare the effects of a combination of colesevelam and clonidine to placebo on bowel symptoms in patients with urge or combined type of FI.
The purpose of this study is to evaluate amino acid absorption with two different type of proteins.
The study will evaluate the effect of NTRA-2112 on intestinal malabsorption in preterm infants.
The study shall investigate whether isomaltulose - is digested and absorbed to a comparable degree like other carbohydrates (CHO) used as ingredients for this age group (e.g. sucrose), by measuring the H2 exhalation in the postprandial period - does not mediate abdominal discomfort or diarrhoea and is therefore as well tolerated as other CHO (e.g. sucrose), by/in healthy infants aged 6 to 12 months. It is hypothesized that isomaltulose, provided with a standard follow-on formula, 1. will not significantly increase the mean basal breath H2-excretion rate (determined as the incremental area under the curve (iAUC) of H2-exhalation) over a 3 h postprandial period compared to a sucrose containing standard follow-on formula. 2. will not lead to a significantly different gastrointestinal tolerance in the conse-quent 24 h after formula consumption compared to a sucrose containing standard follow-on formula in infants aged 6 to 12 months.
Background: The association of fructose and lactose intolerance and malabsorption with the symptoms of different functional gastrointestinal disorders (FGID) is unclear. The mechanisms behind the multi-organ symptoms remain unclear. Both FGID and saccharide intolerances are common (>10% of any given population). Dietary modification based on intolerance diagnostics could provide an effective treatment for FGID, which are otherwise difficult to treat. Aim: To investigate the prevalence and interrelationships of fructose and lactose intolerance (symptom induction) and malabsorption (breath test gas production) and their association with clinical GI as well as non-GI symptoms in FGID and the outcome of standard dietary intervention. Mechanisms related to symptom genesis will be investigated using metabolomic analysis of plasma and urine by gas chromatography/time-of-flight mass spectrometry (GC/TOFMS). Methods: Fructose and lactose intolerance (defined by positive symptom index) and malabsorption (defined by increased hydrogen/methane) will be determined in successive male and female FGID patients in a single center using breath-testing. Symptoms will be recorded using standardised questionnaires and the Rome III criteria. The prevalence of the intolerances in the different FGID subgroups and the associations between breath testing results, clinical symptoms and the outcome of dietary modification will be assessed. Factors predictive of the outcome of dietary modulation will be screened for. GC/TOFMS will be used to assess the human and microbial metabolome in urine and plasma.
The purpose of this trial is to determine the efficacy and safety of A3384 administered to patients with Bile Acid Malabsorption (BAM)/Bile Acid Diarrhoea (BAD).
The purpose of this study is to determine if patients with unexplained iron deficiency have underlying diseases processes such as celiac disease. It is hypothesized that selectively screening patients with unexplained iron deficiency will reveal previously undiagnosed etiologies, including celiac disease and other causes of iron malabsorption along with various sources of occult GI blood loss.
Dietary fiber is a type of carbohydrate which is not digested in the human small intestine. Whole grains are a source of dietary fiber that are used to promote health; however, using whole grains in commercial products results in a different taste and/or texture than the usual products made from refined grains. Thus, other types of high-fiber ingredients have been developed which can be incorporated into food products with less effect on their taste and/or texture. An example of this is resistant starch, defined as starch which is not digested in the human small intestine. The digestibility of starch is usually determined in-vitro; however, there is evidence that such methods may overestimate the amount of resistant starch by as much as 100%. The measurement of the amount of carbohydrate in the ileal effluent, digestive waste, of subjects with an ileostomy is considered to be the best in-vivo method of starch digestibility. The subjects collect ileal effluent during the day during which time they consume a polysaccharide-free diet. There is evidence that resistant starch consumed at breakfast is completely recovered in ileal effluent 8-10hr after consumption. The purpose of this study will be to compare the carbohydrate content recovered in ileal effluent of 10 subjects with a conventional ileostomy.
Patients with fat malabsorption due to Crohn's disease, ulcerative colitis, or other causes including cystic fibrosis, among others, or who have undergone gastric bypass have increased incidence of vitamin D deficiency relative to the general population. Given that vitamin D is fat soluble and absorbed in the proximal small intestine, it has been documented that vitamin D deficiency in people with a fat malabsorption syndrome is due to decreased absorption of vitamin D. The amount of vitamin D produced from winter sunlight (in Boston, MA) and dietary sources will negligibly raise blood vitamin D levels in these patients, and oral vitamin D supplementation may have limited efficacy due to malabsorption. A variety of UV light sources have been developed and sold as in-home tanning devices and to produce vitamin D in reptiles. The efficacy of correcting vitamin D deficiency by the skin exposure to an artificial source of UVB radiation in patients with fat malabsorption syndromes (Crohn's disease, ulcerative colitis, or cystic fibrosis) or after gastric bypass surgery has not been studied. The investigators have conducted a pilot study in healthy adults that demonstrated that exposure to the lamp raised the blood level of 25-hydroxyvitamin D with no side effects. The main purpose of this study is to evaluate the effect of the FDA approved artificial source of ultraviolet (UVB) radiation (Sperti® lamp) in improving vitamin D status in patients with fat malabsorption syndromes and patients who have undergone roux-en-Y gastric bypass surgery.
