Filter by:The goal of this study was to investigate the efficacy and safety of LRG-002 investigational medicinal product, capsules (Lek d.d., Slovenia) in comparison with placebo, as an adjunct treatment for prophylaxis of antibiotic-associated diarrhea (AAD) in patients with acute respiratory diseases (ARDs) receiving a standard antimicrobial therapy.
This study aims to address the paucity of accurate incidence data of diarrheal diseases associated with Shigella in Zambia and Burkina Faso. Given the limited feasibility of the current complex diagnostic methods used to detect Shigella in endemic and developing countries due to the costs, the none availability of reagents and a requirement of expensive and complex machinery, we suggest to use a rapide, easy-to-use, cost-effective, and robust Polymerase Chain Reaction (PCR) based rapid tool, the Loop-mediated isothermal amplification (LAMP) based diagnostic assay (ES-RLDT). This baseline study will enable us to generate an accurate estimate of Shigella incidence so as to inform future trials' designs of an oral vaccine development (ShigOraVax) in Burkina Faso and Zambia. This project is part of the EDCTP2 programme supported by the European Union under grant agreement "No RIA2018V-2308
This study is a randomized, placebo-controlled, single-masked (blinded), post-marketing clinical study of a drug Lactobacillus Reuteri NCIMB 30351 drops in functional disorders of gastrointestinal tract and skin symptoms of food allergies in children between the ages of one and four months inclusive. The aim of the study is to assess clinical effects of probiotics Lactobacillus Reuteri NCIMB 30351 drops on the symptoms of infantile colic, constipation, diarrhea, gastroesophageal reflux, atopic dermatitis/eczema in full-term newborns during the first months of life, laboratory parameters of microbiome will also be assessed. A prospective study comparing two treatment groups: Group 1 (treatment group) - 60 infants. Group 2 (control group) - 30 infants, placebo. The study drug will be taken in 1 time per day within 25 days. Allowed symptomatic therapy includes defoamers (simethicone-based preparations), carminative preparations (dill water (fennel)), etc.
Acute diarrhea and acute colitis of infectious origin are common reasons for consultation at the emergency department. The current etiological diagnostic approach is limited to the determination of markers of inflammation, such as CRP and blood leukocytes, which lack specificity and sensitivity for bacterial infection. The stool culture can detect bacterial pathogens in the stool with a result at least 48 hours later and a positivity rate <50%. This study will describe the procalcitonin (PCT) concentrations (a biomarker of bacterial infection) in this population to evaluate its usefulness depending on the viral or bacterial etiology identified by stool multiplex gastro-intestinal PCR panel (GI panel) and stool culture. The investigators hypothesize that PCT levels will be higher if the GI panel or the stool culture identifies a bacteria or a parasite, as it is the case in respiratory tract infections. If there is a detection of a virus by the GI panel or both the stool culture and the GI panel are negative, the investigators expect that PCT values will be lower or negative. the investigators will include the patients admitted to the ED with a suspicion of infectious diarrhea or acute colitis in order to have a large representative panel of infectious diarrhea etiologies. Only the patients having a blood sample prescribed as the routine care will be included. The blood sample is useful for dosing CRP and whole blood cell count (WBC), which are part of current biologic analyses performed in this context. After getting the patient's consent, the investigator will add the PCT dosage in blood sampling and will ask the patient to provide a stool sample, in order to have a stool culture and to perform an extended investigation for the pathogens through multiplex PCR technology (Filmarray ®GI panel). The physician will be asked if all these results (the ones ordered currently together with the dosage of PCT and the GI panel) will change his/her decision to start an antibiotic. Patients will receive a phone call at day 15 after their initial admission in the emergency department and will be asked if he/she has consulted a new physician or if a new treatment by antibiotics was started. Data collection procedures: Data from the medical file will be collected by the investigators and the emergency department clinical research assistant. All the data will be pseudonymized. The collection will be done at the day of admission in the emergency department and after the phone interview at Day15.
To investigate the use of antibiotic prophylaxis in patients undergoing TURP and TURB. The investigators set up a prospective, randomized controlled trial in which (after exclusion of risk factors) patients will be randomized in receiving levofloxacin (Tavanic) orally or no antibiotics. The exclusion criteria for TURP are a pre-operative transurethral catheter or > 100 urinary white blood cells in the pre-operative urine sample. The exclusion criteria for TURB are a pre-op catheter or clinical signs of infection.
Acute diarrhea in children is a public health problem. It is estimated that children under 3 years are subject to 1 or 2 episodes of diarrhea per year in Europe. These diarrheal episodes are frequent, expensive and responsible for many consultations and hospitalizations in developed countries. The origin of diarrhea in children is viral in about 70% of cases. The diagnosis of a viral infection is often considered without microbiological evidence. However, microbiological evidence is recommended for certain categories of patients. The involvement of bacteria or parasites in the child's diarrhea does not seem negligible. The main objective of this study is to estimate the prevalence of infectious diarrhea among summer diarrhea in children leading to pediatric emergency room visits. Secondarily, we will describe the pathogens responsible for childhood diarrhea during the summer period, describe common factors that can serve as guidance on the etiology of diarrhea, and describe common factors that can be used as tools. preventive to the transmission of these pathogens.
This study is intended to evaluate: 1. Any changes in the gut microbiome from baseline compared to end of study in both healthy (HIV-negative) subjects and HIV+ patients with or without chronic diarrhea, following one month of treatment with crofelemer (Mytesi), delayed release 125 mg tablets twice daily (BID) following one month of treatment. 2. The safety and tolerability of crofelemer, (Mytesi) delayed release 125 mg tablets BID in healthy (HIV-negative) volunteers and HIV+ patients following one month of treatment.
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.
