Active clinical trials for "Pneumonia"

Pneumonia is one of the most common infections in the emergency department (ED). Nevertheless, the current diagnostic tools are often slow and inaccurate. Currently, a chest x-ray is the first choice for diagnostic imaging for pneumonia in the ED, but is inaccurate with low sensitivity and specificity, resulting in both over-and underdiagnosing of pneumonia. Alternatively, computer thermography (CT) and high-resolution CT (HR-CT) offers high diagnostic accuracy but involves significantly increased radiation to the patient, and increased costs and examination time. Lately, two alternatives to chest x-ray have emerged: The first is lung ultrasound (LUS) which has shown higher sensitivity and specificity for pneumonia than a chest x-ray when performed by experts. However, the diagnostic accuracy of lung ultrasound performed by novice operators in the ED still needs investigation. The second alternative to chest x-ray is ultra-low-dose CT (ULD-CT). A ULD-CT is a CT scan where the radiation dose is significantly reduced, while still maintaining acceptable image quality. In effect merging the high diagnostic accuracy of chest CT with the low radiation doses of chest X-ray. The aim of this study is to investigate the diagnostic accuracy of LUS by novice operators in the ED and the diagnostic accuracy of ULD-CT thorax, in patients suspected of having pneumonia.

The objective of this study is to investigate the effect of the infection control measures based on the active screening of carbapenem-resistant Klebsiella pneumoniae and whole-genome based tracking and surveillance though the hospital.

This is a phase 3 clinical trial, randomized, single-center, opened, controlled, to evaluate efficacy and safety of early administration of colchicines in patients older than 60 years, with high risk of pulmonary complications due to coronavirus SARS-CoV2 (COVID-19). An approximately number of 954 subjects meeting all inclusion and none exclusion criteria will be randomized either to receive colchicines or symptomatic treatment with paracetamol during 21 days.

Molecular testing (e.g PCR) of respiratory tract samples is the recommended method for the identification and laboratory confirmation of COVID-19 cases. Recent evidence reported that the diagnostic accuracy of many of the available RT-PCR tests for detecting SARS-CoV2 may be lower than optimal. Of course, the economical and clinical implications of diagnostic errors are of foremost significance and in case of infectious outbreaks, namely pandemics, the repercussions are amplified. False positives and false-negative results may jeopardize the health of a single patient and may affect the efficacy of containment of the outbreak and of public health policies. In particular, false-negative results contribute to the ongoing of the infection causing further spread of the virus within the community, masking also other potentially infected people.

The prognosis of patients with severe COVID-19 disease, whose lungs are so severely diseased that they need to be supported by veno-venous ECMO (extracorporeal membrane oxygenation), is difficult to assess so far. Previously published data from studies, case reports and case series describe a very high mortality in this patient collective. The significance of established clinical prognostic cores in this patient population has not been systematically investigated. This is aggravated by the fact that even at very specialized centers only very few patients from this collective are (can be) treated, so that valid investigations are only possible in a multicenter patient collective. In this registry study, all patients diagnosed with COVID-19 and treated with vv-ECMO in the centers participating in the study should be retrospectively examined. The primary aim of the study is to investigate 30-day survival, secondary objectives include the analysis of different clinical scores at the time of ECMO implantation.

The effect of endotracheal cuff pressure measurement technique for preventing ventilatory associated pneumonia.

The purpose of this study is to gain understanding of mechanisms whereby bariatric surgery modulates pulmonary inflammation and pulmonary microbiome composition and how these changes direct the pathobiology of human obese asthma.

This study is a multicenter randomized controlled trial. The purpose of this study is to assess the efficacy of the combination of PCR and CRISPR/Cas12a in alveolar lavage fluid for early targeted anti-infective therapy for patients with severe pneumonia. Hosted by the Department of Critical Care Medicine, Affiliated Drum Tower Hospital of Nanjing University Medical College, 5 adult ICU units participate in 3 hospitals. All patients are randomly assigned to the experimental group and the control group. For experimental group, the combined detection of PCR and CRISPR/Cas12a in the alveolar lavage fluid was carried out in the early stage, and the antibiotic scheme is changed base on the results of PCR-CRISPR/Cas12a.The patients in the control group were adjusted according to the traditional microbial detection methods. The types of early antibiotics, the proportion of target antibiotics, the duration of anti-infective treatment, the length of hospital stay in ICU, the mortality rate, the secondary antibiotic-associated diarrhea, and the incidence of new multidrug-resistant infections were recorded.

Ventilator-associated pneumonia (VAP) is an important cause of prolonged intensive care unit and hospital length of stay, healthcare costs and mortality in mechanically ventilated patients. There are an international guidelines for VAP diagnosis, treatment and prevention (Infectious Diseases Society of America(IDSA)/American Thoracic Society (ATS) 2016 and European Respiratory Society (ERS) / European Society of Intensive Care Medicine (ESICM) / European Society of Clinical Microbiology and Infectiuos Diseases (ESCMID) / Asociacion Latinoamericana del Torax (ALAT) 2017) routinely used in most ICUs. The investigator planed on comparing two strategies for prevention of VAP in mechanically ventilated patients: the routine VAP bundle ( historical group - VAP1) and the modified VAP bundle ( study group - VAP2) by using 3 modifications ( Shiley Evac Endotracheal tube with TaperGuard Cuff, Automatic continuous subglottic secretion drainage (SSD) and continuous tube cuff pressure monitoring). The aim of the study is an assessment of the effectiveness of the modified prevention of VAP in reduction of: early and late VAP cases, mechanical ventilation days (MV), length of stay (LOS) in the ICU, 28 day mortality and multi drug resistent pathogens (MDR) cases in adult ICU patients.

Pneumocystis jirovecii pneumonia (PjP) is a rare infectiouse disease with a high level of mortality. PjP is a classical opportunistic infection which concern HIV infected and immunocompromised patients. During the past decade, several therapeutic's progresses have been done in oncology, immunology and hematology. As a consequence, patients benefited of greater treatment efficacy but are exposed to a higher risk of opportunistic infections as PjP. The investigators hypothesis is that PjP incidence increase and its form is depending of underlying immune conditions. The investigators aim to describe its incidence, the PjP forms depending on comorbidities and to identifiy pronostics factors.
