Filter by:The purpose of this study is to evaluate the immune response and safety of the inactivated poliovirus (IPV) vaccine when co-administered with the human rotavirus (HRV) porcine circovirus (PCV)-free vaccine in healthy Chinese infants 6-10 weeks of age at the time of study enrolment.
The goal of this clinical trial is to compare amino acid-fortified oral rehydration therapy (ORT) to the standard of care ORT in pediatric patients with acute gastroenteritis (AGE). The main questions it aims to answer are: - can amino acid-fortified ORT reduce the duration and severity of AGE compared to standard of care ORT? - can amino acid-fortified ORT increase the secretion of antimicrobial peptides in the gastrointestinal tract compared to standard of care ORT? Participants will be assigned to the experimental treatment (amino acid-fortified ORT) or the standard of care ORT and their disease severity, duration, and stool antimicrobial peptide content.
The purpose of this study is to evaluate the immunogenicity, reactogenicity and safety of the Porcine circovirus (PCV)-free liquid formulation of GlaxoSmithKline Biologicals' SA (GSK) oral live attenuated human rotavirus (HRV) study intervention compared to GSK's liquid oral live attenuated HRV study intervention in healthy Chinese infants 6 to 16 weeks of age at the time of the first study intervention administration.
This is a randomized, double-blind, phase 3 study to evaluate the Efficacy, Safety, and Immunogenicity of ROTAVAC 5D, a live attenuated rotavirus vaccine in healthy infants. A total of 5800 healthy Chilean infants will be recruited in this study and randomized to receive either vaccine or placebo in 1:1 ratio. Among these participants 300 will be categorized to immunogenicity cohort, 150 from each group, and blood samples will be collected to assess the immune response.
This protocol describes the challenge non-typhoidal Salmonella (CHANTS) study. This is a first-in-human phase 1, double-blinded, randomised, dose-escalation human infection study, conducted in healthy volunteers aged 18 to 50 years. The primary objective of the study is to perform a dose escalation with two strains (ST19 or ST313) to determine the infectious dose required for 60-75% of volunteers to develop Salmonellosis using a composite diagnostic criterion. The secondary objectives of the study are to describe and compare the clinical and laboratory features following controlled human infection. It is hoped that the successful establishment of an NTS human challenge model can be used in the future to test candidate vaccines for NTS disease.
The purpose of this study is to determine whether lactose-free milk will change diarrhea duration and severity in formula-fed infants with acute gastroenteritis presenting to pediatric wards.
Compare the effectiveness of automatic vs as-needed (PRN) post-hospitalization follow-up for children who are hospitalized for common infections.
Hypernatremic dehydration (HND) is a common and potentially life-threatening condition in children. It is defined by a serum level of sodium greater than or equal to 145 mmol/L . HND is a type of acute dehydration constitutes a medical emergency and requires a rapid diagnosis for adequate and quick management. It is characterized by a deficit of total body water (TBW) relative to total body sodium (TBS) levels due to either loss of free water, or excessive administration of hypertonic sodium solutions. It is common in infants. Net water loss as seen in diarrhea is the most common cause of hypernatremia. Clinical interventions at the hospital settings or accidental sodium loading usually cause hypertonic sodium gain. It is common in developing countries where gastroenteritis is a common problem. Most children with hypernatremia are dehydrated and have the typical signs and symptoms as weight loss, decreased skin turgor, pale skin color, and dry mucous membranes. Hypernatremia, even without dehydration, cause central nervous system symptoms according to the degree of sodium elevation and the acuity of the increase. Patients are irritable, restless weak, and lethargic. Some infants have a high-pitched cry. Alert patients are very thirsty, although nausea and fever may be present. HND can lead to neurological impairment due to brain shrinkage, which can tear cerebral blood vessels, leading to brain hemorrhage. Cerebral hemorrhages are the most serious complications of HND that can eventually lead to convulsions and even coma . The first priority in managing a child with HND is to stop the ongoing water loss by treating the underlying cause. The next step is to restore the intravascular volume with isotonic fluid. Dehydration can be treated with oral, nasogastric, or intravenous fluids. The child is given a fluid bolus, usually 20 mL/kg of the isotonic solution, over about 20 to 30 minutes. More severe dehydration needs repeated boluses at a faster rate. After the fluid bolus is given, the signs of dehydration should be reassessed in order to confirm a complete rehydration. Fluid loss should not be corrected rapidly. Cerebral edema as well as convulsions is serious risks during rapid rehydration, so correction of deficit should be achieved slowly and gradually over 48 hours and should not be decreased to less than 12 mEq/L. To prevent cerebral edema and convulsion, individuals with hypernatremia should be managed in such a way that the reduction rate of serum sodium occurs at approximately 10 to 12 mmol/L/24 hr. Cerebral edema and seizures can be consequences of rapid correction of serum sodium level in these patients in whom the rate of fluid and sodium administration are inappropriate
Background: Acute viral gastroenteritis is a very common pediatric medical condition that results in a large number of emergency department (ED) visits. Fasting-induced ketosis has been suggested to contribute to nausea and vomiting in children with VGE. To date, there is no data on the impact of oral sucrose intake during oral rehydration. Objective: The aim of this study is to assess the impact of providing a sucrose solution at triage to young children with suspected acute viral gastroenteritis on the amount of rehydration solution intake in the first 2 hours. We will also assess the proportion of discharge after initial medical evaluation, the proportion of oral rehydration failure, the number of vomiting episodes per patient, ondansetron administration, the time between the intervention and ED discharge, the time between the first medical contact and ED discharge and return visits within 48 hours. Methods: This study will be a double-blind randomized controlled trial. Recruitment will take place in a tertiary pediatric ED. Participants will be all children who present to the ED with suspected acute acute viral gastroenteritis with at least three vomiting in the previous 24 hours. The intervention will consist in giving 1.5 ml/kg of a sucrose solution composed of diluted juice with added table sugar (3.5g of sucrose/10 ml) compared with 1.5 ml/kg of diluted juice (0.5g of sucrose/10 mL, standard of care in our ED). Following that, all participants will be rehydrated with 15 mL of diluted juice every 15 minutes or more if tolerated. The primary outcome will be the amount of rehydration solution (ml) absorbed in the first two hours following intervention. Secondary outcomes will include disposition after initial medical evaluation, oral rehydration failure, the number of vomiting, ondansetron administration, the time between the intervention and ED discharge, the time between the first medical contact and ED discharge and return visits within 48 hours. The primary analysis will be the difference in the amount of tolerated oral rehydration between the two groups. Based on a preliminary study of children suffering from VGE, it was estimated that the recruitment of 238 participants would provide a power of 80% to identify a difference of 15 ml between the two groups. Expected results: We hope that this study will demonstrate that an oral sucrose solution given at triage to children presenting with symptoms compatible with acute acute viral gastroenteritis promotes oral hydration and consequently increases the total amount of rehydration solution tolerated by children.
In children with acute gastroenteritis (AGE), vomiting often precedes diarrhea. To establish the diagnosis of AGE, enteropathogen detection typically relies on diarrheal stool samples. However, testing requires sufficient stool sample, which may not be easily available. Recent studies suggest that in children presenting to emergency departments with presumed AGE with isolated vomiting, an enteropathogen can be identified using rectal swabs and molecular diagnostic tests. The rate of enteropathogen detection in children with isolated vomiting due to AGE may differ in various populations. Using rectal swabs and molecular diagnostic tests, we plan to assess the proportion of children with isolated vomiting with presumed AGE in whom an enteropathogen can be identified. This will be a prospective cohort study. Children younger than 5 years with presence of ≥3 episodes of vomiting due to presumed AGE, lasting no longer than 7 days before enrolment, will be recruited. A total of 198 participants will be recruited and a rectal swab will be collected. The participants will be contacted 14 days after enrollment to complete a survey regarding symptoms experienced during that period and to identify any additional clinical care.
