Filter by:In the United States, healthcare providers prescribe over 270 million antibiotic prescriptions each year. While antibiotics have transformed medicine and methods of treating life-threatening bacterial infection, broad spectrum antibiotics also induce disruption of resident gut microbial communities by altering both composition and function. This disruption of microbial community dynamics has been demonstrated at the taxonomic level, yet the extent of functional disruptions to microbial metabolic output and host cells remains understudied in humans. This study explores the impact of a broad spectrum antibiotic cocktail on microbial communities throughout the gastrointestinal tract, and the impact of a defined, multi-strain consortia of probiotic organisms following antibiotic exposure.
Amoxicillin-clavulanate is an antibiotic commonly prescribed to treat a myriad of community-acquired infections. One of the most common adverse effects of amoxicillin-clavulanate is antibiotic-associated diarrhea (AAD). Studies have shown that administration of antibiotics can cause disruption and changes in the diversity of microorganisms within the gut (gut microbiome), with overgrowth of "harmful" bacteria as a possible driver for AAD. How antibiotics specifically affect the gut microbiome to cause AAD in humans, however, remains unknown. The overall goal of the study is to characterize the changes in the gut microbiome over time, in subjects who develop AAD after antibiotic ingestion, and to further demonstrate that resolution of AAD is due to return of "friendly, anti-diarrhea bacteria". The study investigators will also measure the proteins produced by the gut bacteria, as a potential tool to help predict which individuals are at risk of AAD. The investigators plan to recruit 30 healthy adult volunteers who will receive 3 days of oral amoxicillin-clavulanate, a very commonly prescribed antibiotic. Stool and blood samples will be collected throughout the study up to 28 days after antibiotic administration. The study investigators will measure and compare the changes in the gut microbiome and metabolic responses in order to identify the relationship between these changes and the onset of AAD. The results from this study will not only yield important scientific knowledge about the pathogenesis of AAD, but will also provide new leads to understand the interplay between the gut microbiome, immune-metabolism and AAD. These findings also have the potential to identify clinically important biomarkers to allow pre-identification of individuals at risk of AAD. If successful, this study could pave the way for personalized medicine for management of bacterial infections. This will help to prevent premature stoppage of antibiotic therapy due to diarrhea side effects, and reduce the risk of bacterial resistance from suboptimal treatment.
This is a nutritional trial with two arms: 1) Intervention arm of Probiotic Yoghurt containing Lactobacillus rhamnosus yoba 2012 and 2) Control arm of custard-like dairy product. The study subjects are 200 children between the age of 3-6 years that attend a school in Southwestern Uganda, Sheema district. Children will be randomized and enrolled in either the yoghurt (100 children) or the placebo (100 children) arm. The children will be monitored for 3 weeks in the baseline in regards to the incidence of common childhood diseases. During these three weeks, stool, saliva and urine samples will be collected. Also measurement of anthropometric indicators (weight and height) will take place. Subsequently, the children will consume either 100ml yoghurt or 100ml placebo product, once per day for five days per week for nine weeks, while being daily monitored in regards to the incidence of common childhood diseases. The same samples (stool, urine and saliva) and assessments (anthropometric) will take place at end line.
A randomized, double-blind, placebo-controlled pilot study in patients with IBS-D according to Rome IV criteria evaluating the clinical efficacy and safety of oral administration of 2g G-PUR® tid compared to placebo in a cohort of 30 patients over an active treatment period of 12 weeks.
The investigational medicinal product (IMP), INM004, proposes to neutralize the toxin in the bloodstream to prevent the interaction of the Stx with the specific receptor, by means of a polyclonal antibody to be administered upon the appearance of symptoms (bloody diarrhea) and diagnosis of infection by STEC, thereby preventing the action of the toxin in the body. Thus, the initial hypothesis for examination is for the prevention of the full expression of HUS, based upon presumptive clinical, biochemical, and other biological evidence suggesting a risk of HUS at the time of treatment application. The polyclonal antibody (F(ab')2 fragment) is obtained by processing the serum of equine animals previously immunized against engineered Stx1B and Stx2B immunogens. INM004 could be administered at the earlier stages of STEC disease since subjects with STEC diarrhea are more likely to benefit from Stx neutralizing antibodies before the development of extra-intestinal manifestations and HUS. Neutralizing equine anti-Stx F(ab')2 antibodies (INM004) have the objective of preventing the development of HUS by blocking the circulating toxins in patients infected with STEC. Therefore, INM004 may be used in patients with a clinical manifestation of bloody diarrhea and a positive Stx result in feces. Early interruption of the Stx mediated cascade is expected to prevent the development of HUS, alleviate the severity of the illness, the rate of complications and the incidence/duration of hospitalizations. Therefore, patients in the early phases of the disease will be targeted in this study, ie, children who seek medical care due to diarrhea associated with STEC infection before HUS development.
This study will evaluate the effects of ORP-101 versus placebo on stool consistency and abdominal pain in patients with Irritable Bowel Syndrome with Diarrhea (IBS-D). It will also assess the safety and tolerability of ORP-101 in patients with IBS-D.
The investigators will perform a multicenter, 2:1 randomized, double-blinded, placebo-controlled trial of AMR in patients with diarrhea predominant-IBS (IBS-D) diagnosed according to Rome III criteria and the IBS-QOL questionnaire. Central supply and quality control of donor material will be used to control bias. Primary endpoint is improvement of IBS-SSS (Severity Score System) compared to baseline. Secondary endpoints include changes in IBS-QOL, short term safety and one year follow up to control long term effects, safety and changes in and acceptance of donor microbiome after AMR using16S rDNA sequencing and quantitative diversity analysis.
The purpose of this study is to determine the efficacy of Bacillus subtilis DE111® probiotic for regulation of bowel movements.
To evaluate the safety, global efficacy and rapidity of action of GT in children with acute gastroenteritis taking ORS solution.
This study evaluates the effect of zinc over the duration, severity and relapse of acute diarrheic disease, in children between 6 and 59 months of age. One study group will receive a tablet that contains 20 mg of zinc, and the other study group will receive a tablet,that does not contain zinc, it is a tablet that investigators will use as control.
