Filter by:Our hypothesis is that the medication approved for treatment of high blood cholesterol levels, Colesevelam HCl (WELCHOL), decreases colonic transit and permeability in patients with diarrhea due to irritable bowel syndrome. This effect is thought to result from the effect of the medication on bile acids, which can cause diarrhea.
The purpose of this study is to prospectively determine the rotavirus VP7/VP4 genotypes associated with moderate to severe disease (requiring emergency room (ER) consult or hospitalization) in a large public hospital from Valparaiso and another from Santiago.
The purpose of this study, is to assess the effect of lanreotide Autogel 120mg on stool frequency in subjects with refractory diarrhea at day 28 (mean of last 7 days) compared to baseline.
The purpose of this study is to study factors (drugs, serum concentration of drugs, nutrition, physical activity, demographics, diseases etc.) related to constipation and diarrhea in nursing homes, and the effect of different laxative regimens.
This research is designed to study the reliability of the results of an AcuGraph in college students and faculty members with reported digestive symptoms
This study will validate a model for testing new vaccines designed to protect against intestinal infections with enterotoxigenic Escherichia coli (ETEC). ETEC is one of the most common causes of diarrhea in developing countries and is a common cause of travelers diarrhea. Vaccines are now being developed and their development will be facilitated if we have a valid model for testing these vaccines in human volunteers. We anticipate that the new vaccines will be given to volunteers and they will then be given a dose of virulent ETEC bacteria. If the vaccine is effective, the volunteers should not development diarrhea, but if the vaccine is not effective, the volunteers will have diarrhea for a few days. During this study, we will validate a minimum dose of virulent ETEC bacteria which is sufficient to cause diarrhea in healthy adult volunteers and to identify conditions that can make this model reliable. We will also determine, in a follow-up group of volunteers, if being exposed to the ETEC bacteria previously will protect against a subsequent illness when they are exposed to the same bacteria a second time. We believe that the previously exposed group will be protected and we will study the immune response to these exposures to help design vaccines that can accomplish this kind of protection.
Prospective randomized double-blind study on the effect of prebiotics (inulin and fructo-oligosaccharides) in the prevention of antibiotic-associated diarrhea in children.
Rotavirus is the most common cause of severe infantile diarrhoea disease in infants and young children below five years worldwide. It is associated with high cases of morbidity and mortality and it is estimated that up to 600,000 deaths in young children occur annually in the less developed countries and approximately 150,000-200,000 deaths occur in Africa alone. In Kenya, most rotavirus surveillance work has been done in Nairobi (an urban setting). Other parts e.g eastern Kenya, limited data is available and hence the prevalence and burden of rotavirus disease is under-estimated. We therefore hypothesize that rotavirus prevalence is high in Meru,Maua (a rural setting)and hence we designed a study to evaluate this. This is a prospective study to determine, the rotavirus disease burden and epidemiology in infants and children with severe diarrhoea hospitalized in three sentinel hospital in the eastern part of Kenya (Maua Methodist hospital) will be carried out during the period January 2009 to December 2010. Faecal samples will be collected from infants and children admitted with acute diarrhoea and screened first for the presence of human serotype A rotavirus antigen using commercially available enzyme linked immunosorbent assay kit (ELISA). The positive samples will be evaluated by sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE) to determine the electropherotypes and genotyped using reverse transcriptase polymerase chain reaction (RT-PCR) on VP7 and VP4 gene. These data/ results generated from this project will add crucial information on the rotavirus strains circulating in the eastern part of Kenya.
A comparison of three medications to treat diarrhea in adults.
Probiotics have been shown to reduce the rate of diarrhea and constipation. The purpose of this study was to investigate if probiotics could improve outcome of hospitalized orthopedic elderly patients.
