Community acquired pneumonia (CAP) is a major cause of morbidity and mortality worldwide. Despite recent improvement in acute management (specifically for administration of antibiotics) many severe presentations of pneumonia worsen, progressing to Acute Respiratory Distress Syndrome (ARDS), a clinical entity with 40% hospital mortality. Dysregulation of immune response is thought to be largely implicated in severe pneumonia progressing to ARDS. Notably, experimental studies have recently suggested the implication of non-conventional T lymphocytes and innate cells in this immunopathology. However, no data are available in Humans in clinical settings. This study aims to explore the role of non-conventional T cells in pneumonia and ARDS, in participants. For this purpose, 100 participants admitted to Intensive Care Unit (ICU) with a diagnosis of CAP will be included, and 50 "control" participants with no pneumonia nor shock. Presence and functionality of non-conventional T cells and innate cells will be explored using flow-cytometry and ex-vivo stimulation, alongside with cytokines productions. These analyses are conducted in the blood, and, for invasively ventilated participants, in tracheal aspirates or broncho-alveolar fluids if available. For each participants included, the analyses are conducted at different time-points during ICU stay: inclusion, day 3, day 8 and day 15. Moreover, participants with ARDS, for whom a post-ICU follow-up program is normally established after discharge, will have blood analysis from blood samples taken during the follow-up visit up to 8 months after inclusion. Immunophenotypage and functionality of non-conventional T cells and innate cells will be compared to clinical parameters and their evolution, between "CAP" participants and "Control" participants", and for each participants, according to the different time-point of analysis, in order to better understand dynamic of innate immunity during pneumonia and ARDS.
Secondary bacterial influenza pneumonia caused by Panton-Valentine Leukocidin Positive Staphylococcus aureus is a rare complication but with poor prognosis. This pathology seems to affect young patients (20-40 years) without any medical history. Since the influenza pandemic of 2009, this complication is more and more mentioned, sought and diagnosed. However, the literature is poor, consisting of case reports, experimental studies on murine models, and low-power studies. The main objective is to evaluate the mortality in intensive care units of patients post-influenza bacterial pneumonia due to a Panton-Valentine Leukocidin positive Staphylococcus aureus
Early-onset pneumonia after out-of-hospital cardiac arrest is frequent. An association between early-onset pneumonia and an increase in morbidity has been reported in this population. The diagnosis of early-onset pneumonia inpatients with out-of-hospital cardiac arrest may be challenging as diagnosis criteria are unspecific in this setting. On the other hand some studies have reported an association between early antibiotics and better prognosis in patients with out-of-hospital cardiac arrest suggesting that early diagnosis and treatment of pneumonia would benefit to patients. Nonetheless, adminitration of antibiotics to any patients with out-of-hospital cardiac arrest would expose to antibiotic patients without infection and woould participate to increase in antibiotic resistance. Therefore, the PP-ACR study aims to evaluate the impact of a diagnosis algorithm including blinded sampling protected brushes on early-onset pneumonia treatment and patient prognosis after out-of-hospital cardiac arrest.
The purpose of this study is to validate the method of analysing Positron Emission Tomography (PET) images to assess lung inflammation. Development of novel therapeutic drugs requires a biomarker which is sensitive to the underlying disease and can respond to therapeutic interventions. PET is a potential imaging biomarker which can target molecular and cellular processes. There is currently no standardised method of analysing PET lung data and a lack of validation for the existing techniques. This study is divided in to two parts. Part A aims to determine the best method to perform 18F-FDG PET/CT lung analysis and how it correlates with cell counts from bronchoalveolar lavage (BAL) samples taken from participants with active pulmonary sarcoidosis. Part B will compare imaging data from healthy volunteers who have either undergone a Lipopolysaccharide (LPS) challenge (whereby the lung is temporarily inflamed) or saline equivalent to determine whether lung inflammation can be detected by 18F-FDG PET/CT. No medications will be given and patients will not be asked to stop or change existing medication.
This is study is to assess pulmonary and systemic effects of exposure to wood smoke. Healthy volunteers will be expose under two different occasion to wood smoke and filtered air under two separated occasions with an interval of 3 weeks in-between. The aim of this study was to determine whether exposure to wood smoke from incomplete combustion would elicit airway inflammation in humans.
This research is to evaluate the effect of different antibiotics (Moxifloxacin Hydrochloride and Sodium Chloride Injection vs. β-lactam antibiotics for injection +/- Azithromycin for Injection) on the early deterioration or progression (<72 h of treatment) of community acquired pneumonia and to study the effect of the early deterioration or progression on the prognosis of community acquired pneumonia.
Diffuse infiltrating pneumonia (DIP) is a severe complication of systemic sclerosis and one of the leading cause of death in this condition. The main objective of this study is to prospectively describe the evolution of DIP overtime and to find prognosis factors.
This is a multicentre, multinational, prospective observational investigation on ICU critically ill patients affected by nosocomial pneumonia, defined as: Out of ICU Hospital-acquired Pneumonia (HAP), Non-ventilator ICU-acquired Pneumonia (NV ICUAP), Ventilator associated pneumonia (VAP) Ventilator associated tracheobronchitis (VAT).
The purpose of this study is to determine the efficacy of C-reactive protein and procalcitonin based guidelines versus standard of care to reduce duration of antibiotic exposure in patients hospitalized with community acquired pneumonia.
