Filter by:This is a safety and infectivity study of experimental human Norovirus genogroup GII.4 administered to 48 healthy non-pregnant adults, 18-49 years of age, negative for COVID-19 by antigen testing at the time of norovirus challenge. Subjects will be admitted to the Vaccine Research Center inpatient facility and challenged with a dose of human norovirus GII.4 challenge strain. The challenge study will be conducted in 3 cohorts of approximately 16 subjects each, 15 subjects will have a functional FUT-2 gene (secretor positive) and 1 subject will have a non-functional FUT-2 gene (non-secretor). Subjects in Cohort 1 will receive 3.5x10^3 copies of norovirus, in Cohort 2 will receive 3.5x10^4 copies of norovirus and in Cohort 3 will receive 3.5x10^5 copies of norovirus. Based on the illness rate of subjects meeting the primary outcome measure in secretor - positive subjects of the initial cohort, the decision will be made with regards to dosing of the second and the third cohorts. Study duration is approximately 12-18 months with subject participation duration of 6-8 months. The primary objective of this study is to determine the optimal challenge dose of Norovirus GII.4 CIN-3 Batch No.: 01-16C3 to achieve illness in > / = 50% of subjects (illness is defined as norovirus infection determined by positive Polymerase Chain Reaction (PCR) and either: a) > / = 3 loose or liquid stools, in a 24-hour period, b) > / = 300 gm of loose or liquid stool in a 24-hour period or c) and/or any episode of vomiting), during the inpatient period.
This study evaluates a new drug, new enteroadsorbent polymethylsiloxane (Enterosgel) in the treatment of rotavirus gastroenteritis in children. Half of the participants received a new drug, polymethylsiloxane and half of the participants received standard treatment - probiotic L. reuteri (BioGaia).
Acute gastroenteritis (AGE) is one of the most common causes of children's morbidity and mortality globally. Oral or intravenous rehydration is the only effective treatment in reducing morbidity and mortality rates in AGE. However, new attempts to identify other therapeutic methods to reduce the symptoms of diarrhea are of interest. The administration of pleuran (β- (1,3 / 1,6) -D-glucan) appears to be such an alternative. In Poland, pleuran is being marketed for treating AGE. Its potential immunomodulatory effect is based on the stimulation of both humoral and cellular immunity. The active substance of the product (pleuran) was extracted by unique and patented technology from Pleurotus ostreatus. The substance was previously isolated, identified and chemically characterized by Karacsonyi and Kunia. Pleuran is registered as a diet supplement and distributed in 20 European and non-European countries. The testing for toxicity was performed by the Institute of Preventive and Clinical Medicine of Slovak Medical University (Final Report No. 5-51/04) and the tests were performed in compliance with the criteria of the Directive of Good Laboratory Practice and Directive 2004/10/EC of the European Parliament and the Council of 11th February 2004. To evaluate the efficacy of pleuran in reducing the duration and the severity of AGE symptoms in children, a randomized, placebo-controlled, fully-blind study has been designed. A total of 120 children will be randomly assigned to receive either Imunoglukan PH4 syrup in the experimental group or matching placebo in the control group. The primary outcome measure will be the duration of diarrhea. The statistical analysis of the results will be conducted in both intention-to-treat and per-protocol approach.
Childhood gastroenteritis establishes gastrointestinal disease and increase the economic burden, and the pediatric population is especially vulnerable to these gastrointestinal infections. The aim of this study is to evaluate the role of intestinal microbiota and their relationship with childhood gastroenteritis.
This is a Phase 2, open-label, extension study to assess the safety and tolerability of AK002, given monthly for up to 26 doses.
Evaluation of the impact of the introduction of multiplex PCR panels on the clinical management of patients with gastroenteritis at the University Hospital of Lausanne, Switzerland.
Rotavirus remains among the leading causes of pediatric gastroenteritis requiring hospitalization in the world. Surveillance studies revealed that more than 90% of the global circulating rotavirus strains were predominated by several major genotypes. Clinical trials and post-marketing studies have demonstrated that the currently available rotavirus vaccine can provide sufficient protection against strains of the prevalent genotypes. However, the emerging strains with new genotypes were increasingly reported in the past decade, an ongoing surveillance of the strain changes is needed in the regions where the pediatric population is either fully or partly immunized. In this project, the investigators will setup a hospital-based gastroenteritis surveillance network by incorporating 8 major hospitals in northern, central, southern and eastern Taiwan. From 2013 to 2015, children aged 5 years or younger hospitalized to one of the 8 sentinel hospitals due to acute gastroenteritis will be screened for rotavirus infection, and viral proteins 7 [VP7] (G type) and viral proteins 4 [VP4] (P type) genotypes of rotavirus will be determined for each infected case. The demographics and clinical manifestations of study subjects will also be collected and analyzed. Through this project, the investigators will be able to detect emerging genotypes of rotavirus and delineate the strain distribution during the two years of study in Taiwan. The investigators can also have more comprehensive understanding of the epidemiology of rotavirus regarding to the incidence, disease characteristics, temporal and geographic variations of severe rotavirus gastroenteritis in Taiwanese children. Results from this project will provide valuable information for future implementation of mass immunization against rotavirus in Taiwan.
- Primary Objective: o To assess the efficacy of the probiotics in reducing the duration of diarrhea in children suffering from acute gastroenteritis. - Secondary Objectives: - To assess the efficacy of the probiotics in improving the frequency and consistency of stools. - To assess the efficacy of the probiotics in avoiding recurrence of diarrhea. - To assess the efficacy of the probiotics on the disease severity. - To assess the safety and tolerability of the studied probiotics.
This is a Phase 2, double-blind, randomized, placebo-controlled study to assess the effects of AK002, given monthly for 4 doses. It is hypothesized that AK002 is more effective than placebo control (alternative hypothesis) in reducing the number of eosinophils per high power field (HPF) in gastric and/or duodenal biopsies before and after receiving AK002 or placebo versus no difference between AK002 and placebo control (null hypothesis).
This study has been designed to compare the liquid formulation of BRV-PV (LBRV-PV) with the lyophilized formulation (ROTASIIL) by testing the vaccine in infants (three doses administered 4 weeks apart, starting at 6-8 weeks of age) in order to demonstrate the non-inferiority in the induction of specific anti-rotavirus IgA antibodies by these vaccines. The study will also evaluate lot-to-lot consistency in the manufacture of LBRV-PV by demonstrating equivalence in the induction of specific anti-rotavirus IgA antibodies across three production lots.
