Active clinical trials for "Pneumonia"

Several treatments have been used in during the Covid-19 pandemic of 2020. Using patients' registries from several hospitals in Paris, the investigators retrospectively analyzed associations between specific treatments, including but not limited to vaccines targeted against SARS-CoV-2, hydroxychloroquine, azithromycin, remdesivir, baricitinib, tocilizumab, sarilumab, lopinavir/ritonavir and oseltamivir; and clinical outcomes including, death and mechanical ventilation.

COVID-19 is a rapidly spreading and very contagious disease caused by a novel coronavirus that can lead to respiratory insufficiency. In many patients, the chest radiograph at first presentation be normal, and early low-dose CT-scan is advocated to diagnose viral pneumonia. Lung ultrasound (LUS) has similar diagnostic properties as CT for diagnosing pneumonia. However, it has the advantage that it can be performed at point-of-care, minimizing the need to transfer the patient, reducing the number of health care personnel and equipment that come in contact with the patient and thus potentially decrease the risk of spreading the infection. This study has the objective to examine the accuracy of lung ultrasound in patients with proven COVID-19 pneumonia.

We hypothesized that diaphragm thickness is concerned in acute respiratory failure of COVID19 patients and its ultrasound measure at the begining of hospitalisation is a good predictor of poor outcome. A prospective observational non intervention study is designed.

Ventilator-associated pneumonia (VAP) is an infection of the pulmonary parenchyma in patients exposed to invasive mechanical ventilation for at least 48 h and is part of ICU-acquired pneumonia. VAP is one of the most frequent ICU-acquired infections. Reported incidences vary widely from 5 to 40%, depending on the setting and diagnostic criteria. The estimated attributable mortality of VAP is around 10%. Investigators will focus this study on the current understanding of the epidemiology and treatment of VAP caused by multi-drug resistant (MDR) organisms. The MDR organisms are significant threats to the prognosis of the ICU patient. They are challenging to treat because of a limited number of newer antibiotics available for treatment. Understanding their distribution and sensitivity pattern may provide clues on how to deal with this significant problem. The current study examines the distribution of MDR organisms in VAP and its incidence and outcome. Investigators will also study the sensitivity pattern of these MDR organisms and how it affects the patient outcome. All patients admitted to adult ICU will be scanned, positive respiratory cultures will be noted, and those with VAP will be studied in detail. Patient data will be collected using the hospital information system.

The main objective of project is to compare validity of sampling methods performed routinely (bronchial secretion, stomach content, oropharyngeal smear) for determination of etiological agent responsible for hospital-acquired pneumonia (HAP) in critically ill patients to bronchoscopy-assisted protected brush method. Evaluation of the present clinical praxis using bronchial secretion sampling in HAP diagnostics and detection of the most common etiological agents in patients with HAP are other priorities of the project. Aiming to confirm or exclude the diagnosis of HAP, determine the sources and possible routes of bacterial pathogens transmission molecular biology analysis of etiological agents is performed. Finally, percentage of HAP etiological agents resistant to initial empiric antibiotic therapy will be observed.

Ventilator-associated pneumonia (VAP) continues to be a major cause of morbidity and mortality in the intensive care unit (ICU). Microaspiration of subglottic secretions accumulated above the endotracheal tube cuff is the primary route of bacterial entry into the lower respiratory tract.Therefore, removal of secretions from the subglottic spacehas been recommended as a preventive strategy to avoid microaspiration and VAP. In this context, whereas considerable literature exists on the use subglottic secretion drainage (SSD) in patients at risk for developing VAP, there is a lack of data on the bacterial growth in the subglottic fluid above the cuff. The primary objective of the study will be to assess the value of subglottic secretion culture in predicting microbial flora of endotracheal aspirate samplein patients admitted to our ICU and under invasive mechanical ventilation for at least 48 hours. Secondary end-point will be to estimate the predictive value of subglottic secretion culture in identifying bacterial pathogens in the sub-population of patients who will develop VAP.

The diagnosis of pneumonia is challenging in Intensive Care Unit. The auto-fluorescence of white corpuscles is altered during pneumonia. In presence of bacterial growth on lung samples, the measure of autofluorescence of white corpuscles could help the clinicians to discriminate bacterial colonization from acute infection.

Investigators in the Division of Infectious Diseases and the Division of Hospital Medicine of The George Washington University Medical Center are carrying out a study to determine if hospitalized patients receiving the polyvalent pneumococcal vaccine during an acute illness develop an adequate antibody response. The study group will consist of individuals diagnosed with pneumonia and admitted to the Medicine ward under the Pneumonia Core Measure Protocol, which assigns appropriate patients for vaccination based on the current guidelines from the Advisory Committee on Immunization Practices (ACIP).

The main purpose of this study is to use an investigational urine assay to estimate the proportion of pneumonia in adults 50 years or older in different areas throughout the US that is caused by certain types of the bacteria Streptococcus pneumoniae (also called pneumococcus).

The study intends to assess the utility of performing a follow up X rays in children admitted to pediatric wards with lobar pneumonia. Usually those children are discharged with a recommendation for a follow up X rays but there are no enough studies proving that this recommendation is really necessary.
