Filter by:Citrulline is an amino acid produced in the intestine and in the liver, but the liver does not contribute significantly to circulating citrulline concentrations. The intestine is thus the only organ that normally releases significant amounts of citrulline into the blood stream. The investigators have designed a study looking at the value of measuring plasma citrulline concentration in patients with tropical enteropathy of mixed HIV status. The focus will be on the ability of the intestine to sustain the individual concerned from a nutritional standpoint. The investigators hypothesise that plasma citrulline concentration is a marker of small bowel absorptive integrity and an appropriate surrogate for HIV related enteropathy.
Probiotic bacteria inhabit the gastrointestinal tracts of healthy individuals and may improve the health status of patients with digestive disease. The first aim of our study will seek to determine if probiotics medication (Bio-Three) inhibit gastrointestinal infection and reduce its inflammatory response in the intestine. The second aim will explore the bacterial count (microbiology) and subsequent immune response in probiotic inhibition of enterocolitis in children. We try to seek to gain an advanced understanding of probiotics versus pathogenic microorganism and host interactions, and mucosal immune responses to probiotics in the intestine.
The purpose of this study is to conduct a translational study in patients with primary eosinophil associated gastrointestinal disorders [EGID] (e.g. eosinophilic esophagitis eosinophilic gastritis, eosinophilic enteritis [EE], eosinophilic colitis, and eosinophilic gastroenteritis [EGE]) with the aim of developing a data bank containing pertinent patient demographic information, tissue samples, and DNA, which will facilitate research on the pathophysiology of inflammatory disorders and the development of a verified successful clinical treatment program.
What is the difference between the use of one drug (Oral Metronidazole) versus the use of this same drug combined with another drug (Rifampin) in treatment of bacteria and infection-associated diarrhea in patients? This infection is an important cause of morbidity and mortality in both the community and hospitals, and the leading cause of hospital and chronic facility-acquired diarrhea. Research is important for the treatment of this infection. Patient care with use of two medication treatment regimens will be studied.
This is a single site study of the effect of montelukast on eosinophil and mast cell counts and activation in the lining of the duodenum in 24 children with dyspepsia in association with duodenal eosinophilia in association with measuring the concentration of the medication in the lining of the duodenum. Patients will be endoscoped with biopsies obtained from the duodenum as part of routine clinical care. Participants in the study will then receive montelukast daily and the endoscopy with biopsies will be repeated on day 21 to measure cell counts and activation and tissue montelukast levels. Cell counts and measures of activation will be compared to pre-treatment levels.
This study will evaluate the safety and usefulness of omalizumab (anti-IgE, Xolair) in reducing eosinophil counts and improving symptoms in patients with eosinophilic gastroenteritis (EG). EG is a disorder of unknown cause in which eosinophils, a type of white blood cell, are increased in the blood and gut tissue. Patients with EG have symptoms like stomach pain, bloating, and vomiting. About 50 percent of EG patients have food or environmental allergies, which may play a role in EG. Some patients with EG improve significantly on diets avoiding foods to which they are allergic. Immunoglobulin E (IgE) is an antibody that plays an important role in initiating allergic reactions. Omalizumab is a monoclonal antibody directed against IgE. The Food and Drug Administration approved omalizumab in 2003 for treating patients 12 years of age and older with allergic asthma. Patients between 12 and 76 years of age with eosinophilic gastroenteritis who have a blood eosinophil count of 500 or more and who have a food allergy or allergy to an inhaled allergen may be eligible for this study. Candidates are screened with a medical history, physical examination, and blood and urine tests. Participants undergo the following procedures: - Leukapheresis. This procedure is done to collect quantities of white blood cells to study the effects of omalizumab on eosinophils and other immune substances. Blood flows from a needle placed in an arm vein through a catheter (plastic tube) into a machine that separates the blood into its components by centrifugation (spinning). Some of the white cells are removed and the rest of the blood (red cells, plasma and platelets) is returned to the body through a needle in the other arm. - Skin testing. Participants are tested for allergies to specific substances. A small amount of various allergens (substances that cause allergies) are placed on the subject's arm. The skin is pricked at the sites of the allergens and the skin reaction after several minutes is observed. - Upper and lower endoscopy. One or both of these procedures is done, depending on the part of the gastrointestinal tract that is involved, to examine the tract. If both procedures are done, they are performed at the same time. For the upper endoscopy, the subject's throat is sprayed with a numbing medicine and a long, flexible tube is passed through the esophagus, stomach and small intestine. For the lower endoscopy, the tube is passed through the rectum into t...
RATIONALE: Octreotide may be effective in preventing or controlling diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer. It is not yet known whether octreotide is effective in treating diarrhea. PURPOSE: This randomized phase III trial is studying octreotide in preventing or reducing diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer.
RATIONALE: Pentosan polysulfate may be effective in treating side effects of radiation therapy to the abdomen or pelvis. It is not yet known whether pentosan polysulfate is more effective than no further therapy for treating gastrointestinal disturbance caused by previous radiation therapy. PURPOSE: Randomized phase III trial to determine the effectiveness of pentosan polysulfate in treating patients who have inflammation of the rectum, diarrhea, or blood in stools caused by previous radiation therapy to the abdomen and pelvis.
