Active clinical trials for "Bacterial Infections"

Retrospective single-center cohort study to evaluate the incidence of colonization by multidrug-resistant organisms (MDRO) in mechanically ventilated patients admitted to a large intensive care unit (ICU) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during the second wave of COVID-19 pandemic (October 2020-May 2021) in Lombardy, Italy. As secondary outcomes, the study evaluates the overall incidence of infections during the ICU stay and assesses the risk factors associated to bacterial superinfection and MDRO colonization.

Breath samples from patients with Ventilator Acquired Pneumonia (VAP) will be analyzed to identify Volatile Organic Compounds (VOC) that have been specifically associated with VAP in previous animal models. Primary outcome measures will include the assessment of the zNose Diagnostic Breath Analysis System in the early detection of VOC's associated with VAP.

To investigate the value of procalcitonin (PCT) kinetics between 0-8-16-24 hours after starting empirical antibiotic therapy in critically ill patients, to predict appropriate or inappropriate antibiotic treatment.

This study concerns patients having had an infection on their prosthesis (hip, knee,..) and for whom a 2-step exchange of prosthesis has been done. A 2-step exchange consists in explantation of the prosthesis and implementation of a spacer at the first stage, and reimplantation of a new prosthesis in a second stage. Patients with late prosthetic joint infection are at risk for superinfection at the time of reimplantation. The aim is to determine the microbiological epidemiology in patients experiencing failure following reimplantation to establish, based on the drug susceptibilities, which cement could be the most active.

A diagnostic accuracy study investigating the accuracy of procalcitonin in diagnosing invasive bacterial infections in your infants.

Cephalic duodenopancreatectomy is part of the curative treatment for pancreatic cancer of the head and peri-ampullary area. The mortality of the procedure is around 5%, with a morbidity ranging from 30 to 50%. Infectious complications account for 35% of overall morbidity. One of the risk factors for postoperative complications is the existence of preoperative retentional jaundice, due to tumoral obstruction of the main bile duct In these cases, it is proposed to perform preoperative bile duct drainage, preferably by endoscopic stenting (ERCP). However, several studies have shown these procedures to cause biliary contamination which could be responsible for an increase in post-operative morbidity such as infectious complications and increased length of stay in hospital.. Thus, the biliary microbial flora is more often multi-microbial and may contain multidrug-resistant nosocomial germs, The study carried out by Cortes et al., based on a control case study design, also showed that a correlation between biliary colonization and postoperative infectious complications existed in patients who benefited from a preoperative biliary drainage technique. In fact, the bacteria isolated during intraoperative bile sampling were similar, in 49% of cases, to those isolated during bacteriological samples collected postoperatively during infectious complications. The work carried out by Krüger and al has shown that the spectrum of bacteria found in the preoperative bile samples from patients who have undergone bile duct dilation is potentially not covered by standard antibiotic therapy. The aim of this observational prospective study is to investigate this correlation between biliary colonization and postoperative infectious complications, to evaluate the morbidity and postoperative mortality of cephalic duodenopancreatectomies performed at the CHRU of Nancy and to study a possible adaptation of perioperative antibiotic prophylaxis.

Helicobacter Pylori (HP) is one of the most common pathogens in humans. This infection can present in children with abdominal pain, vomiting and iron deficiency. The treatment is usually empiric and includes antibiotic treatment usually Amoxycillin and Clarithromycin or Metronidazole. Between 40 to 70 % of the pathogens are resistant to those drugs, and it is important to characterize the specific sensitivity of the pathogens in any specific area and in pediatric population. The aims of this study is to assess the sensitivity of HP in pediatric population in Northern Israel.

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.

The primary objective is to study the value of serum procalcitonin as a predictive marker for severe bacterial infection in febrile infants. 2200 febrile infants aged less than 3 months will prospectively be included. All infants will have a measure of Procalcitonin concentrations. Comparison of the mean value of Procalcitonin concentration in infants with and without serious Bacterial infection. Evaluation of the area under the ROC for Procalcitonin concentration.

The purpose of this study is to develop a scoring system to allow doctors to accurately identify children on a mechanical ventilator who have bacterial pneumonia. Currently this diagnosis is very difficult to make, resulting in the overuse of antibiotics and the promotion of antibiotic-resistant bacteria in the pediatric intensive care unit (ICU). Four ICUs at 3 children's hospitals will participate. Study participants will include 150 children, ages 2 months to 17 years old who require mechanical ventilation, and in whom the bedside health care providers suspect bacterial pneumonia. Bacteria will be studied by sampling lung fluid through the breathing tube less than 12 hours after starting antibiotics, using a procedure known as "non-bronchoscopic-bronchoalveolar lavage (NB-BAL)." Participants may be involved in study related procedures for up to 31 days.
