Active clinical trials for "Pneumonia, Ventilator-Associated"

This study will assess the role of pentraxin3 (PTX3) in the early diagnosis of ventilator-associated pneumonia (VAP) and the detection of antibiotic sensitivity for different organisms isolated from tracheal aspirate.

The aim of this study is to report our experience with ceftolozane-tazobactam and to evaluate its safety and efficacy in the treatment of ICU dependent nosocomial respiratory tract infections due to extensively drug resistant Pseudomonas aeruginosa. Different dosing regimes of ceftalozane-tazobactam is evaluated and compared to the standard therapy of Colomycin.

this study aims to verify the adequacy of doses of antibiotics prescribed in clinical practice for the treatment of ventilated acquired pneumonia (VAP) in the intensive care unit (ICU) with the pharmacodynamic efficacy criteria considered relevant literature. The impact of these pharmacodynamic parameters on the clinical and microbiological VAP will be evaluated.

This study is observational and double blind. It evaluates the validity of presepsin (a serum biomarker of bacterial infections) as early biomarker of Ventilator Associated Pneumonia. It will be measured at day 0 (ICU admission) and every 48 hours in every patient with Sars-Cov 2 interstitial pneumonia requiring invasive mechanical ventilation (see inclusion ad exclusion criteria) until Day 30, ICU discharge or ICU death. There will be no change in clinical practice and in pneumonia diagnosis. We will examine how the elevation of presepsin level could be an early marker of ventilator associated pneumonia or a marker of bacterial pneumonia at ICU admission, before the microbiological results or clinical diagnosis.

In this study; in patients undergoing mechanical ventilation, making the day series Endocan measurements during the first 5 day to look at whether there is a relationship between the levels of VAP with Endocan. This relationship, if any, aimed to investigate whether correlated with clinical and laboratory findings [presence of fever, pathological lung X-ray, the number of white blood cells (WBC), procalcitonin (PCT), C-reactive protein (CRP)] .

Ventilator-associated pneumonia (VAP) is very common in the intensive care unit (ICU), affecting 9 to 40% of ICU patients and mortality rates range from 20 to 50% and may reach more than 70% when the infection is caused by multi-resistant and invasive pathogens. The most common pathogens that cause VAP are the Gram(-) bacteria. Findings indicate that TLRs serves as an important signal in the generation of protective innate responses to bacterial pathogens of the lung and that is required for effective innate immune responses against Gram-negative bacterial pathogens. There is genetic evidence that mutations in TLRs increase the risk of developing nosocomial infections. Understanding the TLR system should offer invaluable opportunity for manipulating host immune responses.

This study is being done to determine if the bacteria found in your mouth (oral flora bacteria) in children admitted to the intensive care unit who need to be on a breathing machine is different from the oral flora in healthy children undergoing anesthesia for their dental caries. Children in the intensive care unit with a breathing tube are at a higher risk for getting a lung infection due to the bacteria in the mouth slipping into their lungs past the breathing tube over several days. This means that bacteria are found in the child's lung when this is normally not the case. If the bacteria in the mouth have changed from normal then they may get a pneumonia.

This project aims to use artificial intelligence (image discrimination) algorithms, specifically convolutional neural networks (CNNs) for scanning chest radiographs in the emergency department (triage) in patients with suspected respiratory symptoms (fever, cough, myalgia) of coronavirus infection COVID 19. The objective is to create and validate a software solution that discriminates on the basis of the chest x-ray between Covid-19 pneumonitis and influenza

Ventilator-associated pneumonia (VAP) refers to a lower respiratory tract nosocomial infection acquired >48h after being intubated in Intensive Care Units. Pathogenesis of VAP is mechanical and associated with microaspiration and leakage of oropharyngeal secretions around the endotracheal tube. A novel approach to VAP will attempt to explore how the abrupt ecological order of acute infection (high bacterial biomass, low community diversity) emerges from the dynamic homeostasis of a pre-existing ecosystem in which lung microbiota and local immunity interaction play their essential role. Therefore, the investigators aim to explore if oral and lung microbiota modifications with local immunity changes, contribute in the pathogenesis of VAP in patients intubated for non-pulmonary reasons. Early changes in the host microbiota with the innate immunity system impairs tissue homeostasis and may represent a new distinct condition and a potential tool for early diagnosis and prevention of VAP.

The purpose of the study is to determine if the clinical course of pneumonia is more severe when both, bacterial and viral pathogens are find as possible causative agent and how does it affect treatment.
