Filter by:Primary objective: To compare the event rate of CDI in groups assigned to ACAM-CDIFF™ vaccine versus placebo in the 9 week period after the third dose of the study vaccine in subjects with first episode of CDI receiving antibiotics standard of care. Secondary objective: To evaluate the safety of all dose groups of ACAM-CDIFF™ vaccine versus placebo in subjects with first episode of CDI receiving antibiotics standard of care.
The balance between immunogenic and tolerogenic activities in human immune system strongly depends on microflora-induced pro-and anti-inflammatory activities. Probiotics are important components of microflora. The interactions of the different strains of probiotics and the cells of immune system are largely unknown. There are many mechanisms by which probiotics enhance intestinal health, including stimulation of immunity, competition for limited nutrients, inhibition of epithelial and mucosal adherence, inhibition of epithelial invasion and production of antimicrobial substances. Fecal immunoglobulin A(IgA), lactoferrin and calprotectin were determined by enzyme-linked immunosorbent assay(ELISA) and compared in different groups. Other clinical symptoms or signs, including fever, vomiting, diarrhea, abdominal pain, bloating abdomen, daily intake and body weight were also assessed. The first aim of our study is to evaluate the role of probiotics and their preparation products on the restoration of intestinal bacterial population. The second aim of our study is determining the immunomodulating effects or anti-inflammatory effects of probiotics on the host (human being). We try to seek to gain an advanced understanding of probiotics versus intestinal microorganism and host interactions, as well as mucosal immune responses to probiotics in the intestine.
The purpose of this study is to determine the effectiveness of probiotics (popularly referred to as 'live active culture' or 'good bacteria') in preventing illnesses and consequent absences from school/daycare centers of children two to four years old that attend daycare at least 3 days per week. Two yogurt drinks will be administered, one containing a specific strain of probiotic, Bb-12. It is hypothesized that children receiving the Bb-12 drink will experience fewer illnesses and absences from daycare. In this study, participants will be asked to: 1. Give their child 4 oz. of the test yogurt each day for 90 days 2. Keep a daily diary of their child's health 3. Collect 3 stool samples from their child at the start, middle, and end of the study 4. Speak with research personnel on a bi-weekly basis regarding their child's health 5. Ensure that their child to consume any yogurts or probiotic-containing products for 110 days of the study
To evaluate and compare the immune responses and safety following a two vaccination regimen by transcutaneous immunization with heat-labile enterotoxin of E. coli (LT) patches or placebo patches.
Diarrhea is a common side effect of antibiotics; it may prolong hospital stay, increase the risk of other infections, develop into more serious forms of disease, and lead to premature discontinuation of the needed antibiotic. The purpose of this study is to examine the safety and effectiveness of a capsule containing Lactobacillus rhamnosus GG in the prevention of diarrhea associated with antibiotic use.
RATIONALE: Calcium aluminosilicate anti-diarrheal (CASAD) may help treat and prevent diarrhea caused by irinotecan. It is not yet known whether CASAD is more effective than a placebo in treating and preventing diarrhea in patients receiving irinotecan. PURPOSE: This randomized phase II trial is studying CASAD to see how well it works compared with a placebo in treating and preventing diarrhea in patients with metastatic colorectal cancer receiving irinotecan.
Irritable bowel syndrome is a common condition affecting 1 in 10 of the population. About a third of these suffer from diarrhoea, which severely impairs their quality of life. Previous studies in Nottingham have suggested that some patients with diarrhoea may have an excess of a chemical called serotonin in their gut. Serotonin stimulates secretion and propulsion in the gut and contributes to diarrhoea. We are interested to see whether a drug, Ondansetron, which blocks the effect of serotonin, would improve symptoms in patients with IBS and diarrhoea. We think the drug may work better in people with a specific gene type so your genetic makeup may be of influence and we would like to test this. Because IBS symptoms fluctuate, one way to determine whether Ondansetron is effective is to perform a randomised placebo controlled trial in which neither the patient nor the doctor knows which medication is being taken in each part of the study.
The purpose of this study is to determine if 600 mg of rifaximin, taken once a day for 14 days by healthy subjects, is safe and effective for the prevention of travellers' diarrhea compared to placebo.
The purpose of this study is to assess the safety and immunogenicity of Peru-15 (CholeraGarde®) vaccine in HIV seropositive adult population of Bangkok Thailand
The purpose of this study is to determine the efficacy of Bio-K+ CL1285 in reducing traveler's diarrhea.
