Filter by:This study is to determine the safety and immunogenicity of an Enterotoxigenic Escherichia coli (ETEC) candidate vaccine, attenuated recombinant Double Mutant Heat-Labile Toxin (dmLT) from ETEC, administered by the Intradermal (ID) route. The sample size has been determined based on the historic sample, not on power calculations.The study will involve 99 subjects (83 vaccinees and 16 placebo controls) in 4 consecutive cohorts of 16 individuals each (13 vaccinees and 3 placebo controls) and the final cohort of 35 (31 vaccinees and 4 placebos) subjects. The primary objective is to assess the safety and tolerability of dmLT vaccine when administered in three doses intradermally over a range of dosages in healthy adult subjects.
The ARIES C. difficile Assay is a real-time PCR based qualitative in vitro diagnostic test for the direct detection of C. difficile nucleic acid in stool specimens.
The purpose of this study is to give children with gastroenteritis with persistent vomiting flavored intravenous ondansetron orally. The investigators test the palatability of the drug and check the serum level of ondansetron at 4 hours .
This is a phase I, randomized, double blind, as well as partially blinded (for Cohort 4), placebo-controlled safety, illness, and infection study of a new experimental human challenge stock of the Norovirus genogroup II, genotype 2 (GII.2) isolate designated Snow Mountain virus (SMV). The study duration is 24 - 36 months. The primary objectives are to: 1) evaluate the safety and reactogenicity of the GII.2 Snow Mountain norovirus challenge stock and 2) determine a safe and optimal challenge dose of GII.2 Snow Mountain norovirus to achieve illness in a high proportion (= / > 75%) of subjects.
Respiratory and gastrointestinal infections are common in children under the age of 4 years, especially after the start of schooling. These conditions are facilitated by a still incomplete functional maturation of the immune system and the anatomical structure and function of the respiratory and gastrointestinal tract still developing. The frequency and duration of these conditions involves a high discomfort and significant costs, in relation to medical appointments, taking medication, the need for hospitalization, days of absence from school and work days lost by parents. Functional foods derived from the fermentation of cow's milk with probiotic strains have been proposed for the prevention of infectious diseases in children. Several products have been investigated, with sometimes conflicting results. Diversity in experimental designs, populations evaluated, and bacterial strains used in the preparation of fermented products are probably responsible for these discrepancies. Recently we started a study approved by the Ethics Committee for Biomedical Activities "Carlo Romano" of the University of Naples "Federico II" (protocol number 210/12) to evaluate the effectiveness of foods fermented with Lactobacillus paracasei CBA-L74 in the prevention of common winter infections in school children aged between 12 and 48 months. Studies of pre-clinical phase showed anti-inflammatory activity of milk fermented with the strain Lactobacillus paracasei L74-CBA in terms of stimulation of the production of the cytokine IL-10 and decreased synthesis of IL-12, also in response to stimulation with Salmonella typhimurium. The data were obtained in in vitro studies on dendritic cells and ex vivo intestinal biopsies as well as in tests on healthy mice and on a mouse model of experimental colitis. A preliminary analysis of the data was found that subjects treated with fermented milk showed fewer infectious episodes, as well as a lower incidence of respiratory tract infections or gastrointestinal, with a statistically significant difference between the study groups. It was also observed a significant increase in the levels of α- and β- defensins, LL-37 and secretory IgA in the group of subjects treated with fermented milk compared to subjects treated with fermented rice or placebo. Therefore, we decided to extend the period of study of five additional months, in order to perform an evaluation of the effectiveness of fermented milk (which was more effective)vs placebo.
Telephone medical advice in general practice is expanding. The Cochrane Database concludes in 2008 that there is not enough data about its use regarding out-of-hours general practitioners workload, emergency department visits, cost, safety and patient satisfaction. The aim of this study is to assess the effectiveness of telephone medical advice given by a general practitioner in a call centre for patient presenting isolated fever or gastroenteritis symptoms.
Gelatin tannate possesses astringent, antibacterial, and anti-inflammatory properties. It is increasingly being marketed as an antidiarrheal drug. A randomized, double blind, placebo-control trial was performed to assess the effectiveness of GT in management of children with acute gastroenteritis.
For a long time, culture was the only way to detect Campylobacter. It appears that rapid immunochromatographic tests (ICT) have detected more positive cases compared to culture, ELISA and molecular tests. The aim of our study is to evaluate the specificity of the ICT which are really interesting tools to use since they allow a diagnosis in about 15 min, in comparison to different methods of detection even serology.
This study will establish the duration of excretion of rotavirus vaccine in stool following vaccination of premature babies hospitalised in a neonatal unit at the time of vaccination.
BioFire Diagnostics, LLC (BioFire) has developed the FilmArray Gastrointestinal (GI) Panel, a rapid, easy to use PCR-based in vitro diagnostic test for the identification of 22 common microorganisms responsible for infectious gastroenteritis (http://filmarray.com/the-panels/) from a stool specimen collected in Cary Blair enteric transport media. The test was made available for sale in the US and EU following FDA clearance and CE marking in May, 2014. The FilmArray GI Panel offers improvements over conventional laboratory testing which include: reduced turnaround time from specimen to result, reduced laboratory labor costs, increased sensitivity and specificity relative to current clinical reference methods, and larger breadth of organism identification than is available using standard methods. Because of these attributes, the results from this test have the potential to enable clinicians to more accurately diagnose and treat GI illness in a reduced time frame. Collaborators at the University of Utah, Brown University/Lifespan, and BioFire Diagnostics have designed a study to evaluate health outcomes of pediatric subjects presenting to emergency departments with GI illness before and after establishing the FilmArray GI Panel as the standard of care method for stool pathogen analysis. It is hypothesized that the rapid (~ 1 hour turnaround time), sensitive, specific, and comprehensive results provided by the FilmArray GI Panel will allow clinicians to more rapidly diagnose GI illness, initiate appropriate therapy and provide guidance when compared to the pre-implementation period.
