Ultraviolet Light And Vitamin D In Subjects With Fat Malabsorption Or After Gastric Bypass Surgery...
Vitamin D DeficiencyGastrointestinal DiseasesPatients 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.

Digestibility of Selected Resistant Starches in Humans
Malabsorption; CarbohydrateIleostomy - StomaDietary 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.
