Carotenoids, vitamin A, and tocopherols serve important roles in many key body functions. However, availability of these compounds may be decreased in patients with short bowel syndrome (SBS) due to decreased oral intake of fruits and vegetables and/or decreased intestinal absorption. Little information is available on serum concentrations of carotenoids, vitamin A, and tocopherols during chronic...
Little data are published on the habitual home oral diet of patients with short bowel syndrome (SBS).We assessed nutrient intake from oral food and beverages in 19 stable patients with severe SBS who live in the southeastern United States. Intestinal absorption of energy, fat, nitrogen (N), and carbohydrate (CHO) was determined in a metabolic ward.We studied 12 women and 7 men, age 48 ± 3 y of age...
Glutamine (Gln) may become conditionally indispensable during critical illness. The short-term metabolic effects of enteral versus parenteral Gln supplementation are unknown in this clinical setting.We studied metabolic effects of intravenous (IV) alanyl-Gln dipeptide (AG) supplementation and enteral (EN) AG supplementation on plasma Gln concentration, antioxidant status, plasma lymphocyte subset...
Antioxidant depletion is common in critically ill patients. This study was designed to determine the effects of parenteral nutrition (PN), with or without glutamine (Gln) supplementation, on systemic antioxidant status in adult patients after major surgery who required PN in the surgical intensive care unit (SICU) setting.Fifty-nine patients in the SICU who required PN after pancreatic surgery or...
