NCT05199532
The purpose of this study is to learn more about Eosinophilic Gastrointestinal Disorders (EGIDs). With this registry we hope to find out more about the symptoms that patients have during their treatment, the quality of life they have with the diagnosis, what the disease looks like throughout the different treatment methods, and if there is a connection between EGIDs and connective tissue disorders. The goal of this study is to be able to better understand EGIDs and use information gained from all the information collected on this study for more precise treatments in the future. We want to create a large collection of samples, called a biorepository, to learn the most about EGIDs as possible. When the samples are collected, which will occur at procedures directed by your child's doctor as part of their standard of care, they will be stored for an unlimited amount of time to perform experiments on these samples and to gather information about EGIDs

NCT01147445
The purpose of this study is to learn if a new candidate vaccine (dmLT) against ETEC (E. coli infection) is safe. This vaccine will be tested to see what effects it has on the body and the ability of the vaccine to help the body resist disease. Researchers want to find the highest dose of dmLT vaccine that can be given without causing severe side effects. Most E. coli bacteria are harmless to humans and can even be beneficial. However, some are harmful, and can cause diarrhea. About 32 healthy adults, ages 18-45, will participate in this study. This study will require volunteers to stay in the research facility for several nights. Participants will be assigned to receive 1 of 4 vaccine doses by mouth. Study procedures include: stool samples, blood samples, and documenting side effects. Participants will be involved in study related procedures for about 8 months.
NCT06579170
Swimming and other recreational water activities at public beaches are increasingly popular leisure activities among Canadians. However, harmful algal blooms caused by blue-green algae (i.e., cyanobacteria) have also been increasing reported at Canadian public beaches in recent years. These algal blooms can cause various acute illnesses among recreational water users through ingestion, inhalation of aerosols, or skin contact with contaminated water. In addition, blue-green algae blooms and their toxins can cause illnesses in pets and wildlife. Currently, baseline data are lacking on the risk of recreational water illness from exposure to blue-green algae blooms in Canada. This study will identify the burden of recreational water illness among recreational water users at four targeted beach sites in Ontario, Manitoba and Nova Scotia, over a two-year period. A prospective cohort study design will be used. The investigators will determine the risk of acquiring acute illness outcomes in recreational water users, as well as their pet dogs, that engage in different levels of water contact at beaches at risk of blue-green algae blooms. The investigators will examine differences in illness risks by gender, age, and location. Relationships between cyanobacterial cell counts, toxin levels, and environmental conditions with the risk of acute illness among participants will be determined. Overall, results will provide important data on the risk of recreational water illness from exposure to blue-green algae and their toxins in Canadian beach settings.
NCT05251909

After completing Part A, participants can continue to Part C - open-label benralizumab treatment period. Following the decision to close enrollment, patients in both Part A and Part C will be given the option to proceed to 6-months of open-label benralizumab treatment in Part D.
NCT03548064
This is a trial to evaluate the safety and immunogenicity of double mutant heat-labile toxin LTR192G/L211A (dmLT) from Enterotoxigenic Escherichia coli (ETEC) by oral, sublingual, or intradermal vaccination in approximately 135 healthy adult volunteers, age 18-45 years. Study duration is approximately 2.5 years, with each participant duration for up to 9 months depending on the route of dmLT administered. There is no specific hypothesis being tested in this study. The primary objective of this study is to assess the reactogenicity, safety, and tolerability of dmLT when administered in three sequential doses, over a range of dosages by oral, sublingual, or intradermal routes.
NCT06882070
Rotavirus is the most common aetiology of serious diarrhoea in young children. Despite antibiotics not being indicated in its treatment, diarrhoea remains a very common cause for antibiotic prescribing in low-income settings. We hypothesized that effective rotavirus vaccination could reduce diarrhoeal episodes and thereby unnecessary antibiotic usage in young children in low-income settings. The study aimed to evaluate the impact of rotavirus vaccination on antibiotic usage. Specifically, the study quantified how differences in rotavirus vaccine efficacy would impact days of prescription and nonprescription antibiotic usage in the first 2 years of life among two large cohorts of children in Zambia and Ghana. The key goal was to understand the effect of rotavirus vaccine efficacy on antibiotic usage and household antibiotic costs. The goal was to generate evidence needed to inform policymakers seeking to introduce new rotavirus vaccines into national vaccination programs, of potential, and often under-appreciated, secondary effects of rotavirus vaccine implementation on antibiotic usage. The study was conducted within a Phase III randomised controlled trial comparing the efficacy of a new parenteral trivalent P2-VP8 subunit rotavirus vaccine to the oral live attenuated vaccine, Rotarix®, against severe rotavirus gastroenteritis in the first 2 years of life in Zambia and Ghana.
NCT05836012
This is a phase 2, multi-country, randomized, double-blind, placebo-controlled trial to evaluate the immune response to routine pediatric vaccinations when co-administered with HIL-214 or placebo in healthy infants.

NCT04174560
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.
NCT06516692
This study will help in determining the impact of assessment of Inferior Vena Cava Collapsibility and Distensibility Index (IVC CI and DI) through Point Of Care Ultra Sound (POCUS), for the fluid management of critically ill patients. This would help in better management of such patients in resource limited countries, where costly equipment for cardiac output monitoring and fluid management are frequently not available. Moreover this study will help in development of future guidelines for fluid resuscitation in critically ill patients.
NCT06568380
Noroviruses are responsible for 700M of annual cases of gastroenteritis, of which 15M are directly related to the consumption of contaminated food, including oysters. Current regulations do not require control of human noroviruses in shellfish. However, an ISO standard recommended to detect their genome in high-risk foodstuffs. However, presence of viral genome doesn't testify to the presence of infectious particles. Routine application of this standard would therefore wrongly lead to the withdrawal of shellfish from market, since norovirus genomes are widely found in the environment and in food without indicating a viral risk. Given the difficulty of cultivating human noroviruses in vitro and thus of discriminating infectious particles from non-infectious particles only based on genome detection, it is necessary to identify an indicator of the infectious nature of these pathogenic viruses. To be suitable, the indicator must first be associated with the presence of norovirus genome in the environment. This is the case of fecal bacteriophage F-specific RNA. Since bacteriophages are cultivable in the laboratory, it is easy to estimate the proportion of genomes of these bacteriophages corresponding to infectious particles. To confirm this indicator, it is necessary to demonstrate a relationship between the presence of infectious bacteriophages with that of infectious norovirus. This is only estimable by the occurrence of a gastroenteritis after consumption of a contaminated food by humans. We propose this randomized controlled clinical trial to evaluate the incidence of norovirus infection after consumption of oysters free from or containing infectious F-specific RNA bacteriophages. The purpose of this study is to evaluate if norovirus infections incidence is significantly weak after the consumption of oysters free of F-specific infectious RNA bacteriophages, compared to the consumption of oysters containing these same infectious bacteriophages.
