Filter by:The purpose of this study is to determine whether the addition of meropenem to colistin is better than colistin alone in the treatment of clinically significant infections caused by multi-drug resistant bacteria
Background: The incidence of gastrointestinal infections is very high. In Western countries at least 30% of the population suffers from at least one food-borne infection per year. Mostly because of the problem of antibiotic resistance, more emphasis is put on prevention of infections. One of the possibilities is to strengthen human resistance to gut infections by consumption of probiotics. A specific blend of probiotic lactic acid bacteria (Lactobacillus helveticus Rosell-52, Lactobacillus rhamnosus Rosell-11, Bifidobacterium longum Rosell-175) and a probiotic yeast (Saccharomyces boulardii), improved stool consistency and shortened the duration of diarrhea in a rat model of E.coli-induced diarrhea. These probiotics showed synergistic effects compared with administration of solely S. boulardii or a mixture of L. helveticus Rosell-52, L. rhamnosus Rosell-11, B. longum Rosell-175. Consumption of S. boulardii and a combination of L. helveticus Rosell-52, L. rhamnosus Rosell-11 reduced diarrhea in humans. Aim: To study whether probiotics improves the resistance of humans to enterotoxigenic E. coli (ETEC). Study design: The PROTETEC study is a parallel, double-blind, placebo-controlled 4-weeks intervention with probiotics in healthy volunteers. In this study, the effect of probiotic intervention vs placebo on several infection markers in response to an ETEC challenge is investigated. Participants will be randomly assigned to the probiotic or placebo group (n=30 per group). Subjects will be instructed to maintain their usual pattern of physical activity and their habitual food intake, but to standardize their dietary calcium intake. After an adaptation period of 2 weeks, subjects will be orally infected with a live, but attenuated, ETEC vaccine (strain E1392-75-2A; collection NIZO food research; dose 10E10 CFU). Before and after infection, a diary will be kept to record all food and drinks consumption (2x2 days) to assess the habitual dietary intake, as well as for daily recording of bowel habits and frequency and severity of gastrointestinal complaints. The following biological samples will be collected: 4x10 ml venous blood, a single fecal bolus (for screening) and 7x24 hrs feces. Blood is sampled for immune response analyses and the fecal samples are collected to quantify several infection- and immune system markers, to determine probiotic excretion, and to verify dietary calcium intake. Study population: Healthy males of 20-55 yrs of age. Interventions: Probiotics (capsules containing freeze-dried powder, probiotic dose per capsule 5x10E9 CFU; twice daily) or placebo (capsules with carrier material powder of identical appearance) Primary outcomes: Fecal ETEC excretion and severity of diarrhea (quantified by fecal output per day). Secondary outcomes: Serum immune response to ETEC, self-reported stool consistency scores and gastrointestinal complaints, relative fecal wet weight. Tertiary outcomes: sIgA and calprotectin in feces, probiotic persistence and levels of opportunistic pathogens in the endogenous microbiota.
RPX2003 (biapenem) is being studied in combination with a beta-lactamase inhibitor to treat bacterial infections, including those due to multi-drug resistant bacteria.
This is a randomised, double-blind, 3-part study designed to investigate the safety and tolerability of ATM-AVI. The study aims to characterise the pharmacokinetics of ATM-AVI, when both drugs are administered alone (ATM or AVI) and in combination (ATM-AVI), following single administration, and following multiple administrations of ATM-AVI in healthy male and female (females of nonchildbearing potential) volunteers both young and elderly.
This is a phase 1, non-randomized, open label, single-dose, two-period, cross-over study. This study will utilize 14C radiolabeled GSK1322322 to investigate the recovery, excretion, and pharmacokinetics of GSK1322322 in 6 healthy adult male subjects through the sampling of blood, urine, and feces. Each subject will participate in the study for approximately 7 to 8 weeks i.e., 30 day screening period, two dosing periods (approximately 8 days each) and a follow up visit. The subjects will be admitted to the clinical unit on Day 1 of the first treatment period and remain in the unit for up to approximately 16 days through the end of the second treatment period. On Day 1 of Period 1, each subject will receive 14C radiolabeled GSK1322322 as a single therapeutic intravenous (IV) dose (1000 milligrams [mg]). When the total radioactivity is <1% of the administered dose in all subjects, Period 2 dosing will begin (approximately 8 days after the IV dose). On Day 1 of Period 2, each subject will receive single therapeutic oral solution dose (1200 mg). Blood, urine, bile and fecal samples will be collected during both the periods. The subject may be discharged from the unit as early as Day 8 of Period 2. Subjects will visit the study unit for the follow-up visit 7 to 10 days following discharge from the unit.
This study is an open-label, randomized, single dose, four period, balanced crossover study to assess in eligible healthy male or female subjects.
For the development of a Point of Care IVD test kit for acute phase disease detection against a variety of bacterial and viral infections. Phase one includes 100 clinical diagnosed positive and 200 clinically "normal" serum and whole blood matched specimens for specificity and sensitivity determination for each marker. The positive samples must be IgM positive using any FDA cleared ELISA test kit. The negatives samples must be negative for IgM.
Peripherally inserted central catheter (PICC) are catheters that are placed mainly in the arms, but which pass in the veins to beside the heart. They are associated with occasional complications due to infection or blockage of the vein that they are in. The investigators want to investigate whether PICCs in the right arm have lower complications than those in the left. This difference in complication rates has been noticed in most other forms of central venous access.
The purpose of this study is to compare between the POCone® to the UBiT®-IR300 in measuring 13CO2/12CO2 ratio in breath samples when used together with the BreathTek® UBT (urea breath test) Kit and the pUHR-CA web-based software program in identifying H. pylori infection in pediatric subjects.
Hospital-acquired infections are common complications in preterm infants. The diagnosis has to be fast and accurate. Indeed, the early identification of a suspected infection is very important, since the early administration of antibiotics lowers the risk of septic shock and improves long term outcome in the infected newborns who survive. Besides, a high specificity in the diagnosis of infection allows for the reduction of inappropriate treatment and thus prevents the emergence of antibiotic resistance. The aim of this study is to develop a computer-assisted diagnosis tool, based on the real time analysis of cardio-respiratory signals, to aid the neonatologist in the diagnosis of infection of the preterm infant, at the bedside.
