Active clinical trials for "Pneumonia"

Hospital Acquired and Ventilator Associated Pneumonia (HAP/VAP) pose a significant burden to patients admitted to the Intensive Care Unit (ICU). Reported incidence ranges from 10-16% in all ICU patients (including HAP and VAP) and around 20-30% in ventilated patients (VAP). Patients with HAP/VAP have a high mortality rate. The estimated attributable mortality of VAP is 6-13%. Randomized Controlled Trials (RCTs) are the gold standard for evaluating medical interventions, but are difficult to perform in this population. Several preventive and therapeutic treatment options are being developed that will require evaluation in phase-III trials. These trials are challenging due to the relatively low incidence of the outcome (e.g. HAP/VAP) or of the domain under study (e.g. specific antibiotic resistant infections) and the requirement of informed consent in critically ill patients. There is a need for a well-organized and well-trained international RCT network that enables efficient execution of a series of RCTs in this population. The aim of the current study is to set up an infrastructure to prospectively enroll patients at risk of HAP/VAP in ICUs in several European countries. Site personnel will be trained to obtain a GCP (Good Clinical Practice) certification (if not already done), to timely identify and enroll patients at risk of HAP/VAP, to timely identify occurrence of HAP/VAP, collect informed consent forms, collect source data, enter data into a clinical database, and use a dedicated system to reply to queries. Site sample collection, processing, identifying the causative organism, and antibiotic susceptibility testing will be validated and adapted if required where possible. Where site infrastructure and regulations allow, the possibility of automated data collection of included participants will be explored to ensure sustainability of the future platform. Furthermore, collected data will be used to inform future diagnostic, preventive and therapeutic trials. E.g. they may support assumptions in sample size calculations and expected number of enrolled participants, they may help in prioritizing interventions, or they may be used in simulations of adaptive trials to optimize decision rules.

Patients older than 18 years of age, with COVID-19 related ARDS (C-ARDS) hospitalized in the ICU and invasively mechanically ventilated will be included in the study. This is an observational cohort study. After informed consent by the next of kin, and within the first 72 hours of invasive mechanical ventilation a blood and a Broncho Alveolar Lavage Fluid (BALF) sample will be collected. If the patients remain invasively mechanically ventilated a second and third blood and BALF sample will be collected every 7-10 days.

Ventilator-associated pneumonia (VAP) remains the most frequent healthcare-associated infection (HAI) in the intensive care unit (ICU) and one of the most critical risk factors associated with both significant morbidity as well as mortality. Although VAP treatment relies on early and appropriate antimicrobial therapy, several preventive measures have been described in the literature in order to limit its incidence and clinical impact in the ICU. Among these, preventing biofilm formation on the inner surface of the endotracheal tube appears to hold promise. Yet there is a lack of clinical relevant data documenting a causal relation between biofilm formation and VAP. Designed to overcome this critical limitation, the BIOPAVIR study intends to provide a better structural and microbiological characterization of endotracheal tube biofilm in critically ill patients at increased risk for the development of VAP in ICU during COVID-19 pandemic.

The aim of this study is to determine the risk factors for development of ventilator-associated pneumonia (VAP) and to identify the prognostic factors of VAP among Coronavirus Disease 2019 (CoViD-19) patients. We hypothesized that CoViD-19 serves as a high risk factor for the development of VAP and it affects clinical outcome measures negatively.

Morbidity, mortality and progress depends on systemic inflammation especially in ARDS patients. Previous studies claims that the proportion of mean platellet volume to platellet which can simply be determined with simple blood tests that are performed at admission, might predict the mortality in ARDS patients. Covid-19 pneumonia has a very similar clinical outlook with ARDS. Therefore we decided to research whether that proportion is legitimate for detecting the progress of Covid-19 pneumonia or not.

Sepsis is a dysregulated host response to severe life-threatening infections, leading to organ failure and death in up to 40% of patients with septic shock. Pulmonary infections are the main cause of community-acquired sepsis and frequently lead to the development of acute respiratory distress syndrome(ARDS). Features of immunosuppression, including diminished cell surface monocyte human leukocyte antigen DR (mHLA-DR) expression, are strongly associated with hospital mortality. Such decrease in HLA-DR expression on antigen-presenting cells has been associated with impairment of microbial antigens to Tcells. Septic patients also show elevated expression of inhibitory receptors associated with cell exhaustion.. Yet, biochemical, flow cytometric and immunohistochemical findings consistent with immunosuppression have been observed in lungs and spleen of patients died of sepsis and multiple organ failure, demonstrating the relevance of studying these defects directly in organ tissues. A novel approach aimed to characterize the role and prognostic value of alveolar biomarkers measured directly in the injured lungs is warranted and supported by: -disappointing results of previous clinical trials attempting to restore the level of biomarkers measured on circulating cells; -evidences of regional immunosuppression in lungs of ARDS patients; -lung is the main site of hospital-acquired infections with a prevalence of ventilator-associated pneumonia in 30% over the course of Intensive Care Unit(ICU) stay in ARDS patients. Investigators speculate that biomarkers measured on alveolar leukocytes (AL) surface, are important predictors of outcome and potential therapeutic targets in ICU patients with pneumonia-associated ARDS. Investigators aim to explore whether biomarkers measured directly on AL from patients with pneumonia-associated ARDS are associated to regional pulmonary immunosuppression using leukocyte functional tests; and predictors of outcomes. Bronchoalveolar lavage fluid(BALF) and blood samples will be collected in ARDS patients. Leukocyte populations and cell membrane biomarkers will be quantified using flow cytometry. Leukocyte functional tests will be performed ex vivo on leukocytes collected from BALF and blood samples. Pharmacological interventions will be performed ex vivo. This project aims to identify biomarkers associated with outcomes and potential therapeutic targets.

We will determine ventilator outcomes to Coronavirus Infectious Disease 2019 (COVID-19) using artificial Intelligence with inputs of chest radiographs and other evidence-based co-variates.

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.

This study is based on the change in weight of hospitalized patients knowing that the diagnosis of malnutrition based on the presence of at least one clinical or laboratory test which anthropometric measures (Evaluation of diagnostic protein energy malnutrition in hospitalized adults ANAES , Guidelines Department, September 2003; HAS Strategy supported in cases of wasting energy and protein in the elderly April 2007). The goal of this study is to find the correlation between hospitalization and weight loss, significant risk factors for malnutrition in a situation of community-acquired pneumonia infection.

Community-acquired pneumonia (CAP) represents a major health care problem and mortality and morbidity associated with severe pneumonia remain considerable, despite state of the art care. While the role of altered DNA methylation in cancer has been widely studied, knowledge of its impact on antibacterial defense is highly limited. In addition, recent preclinical studies showed that the gut and respiratory microbiota contributes to host defense against bacterial pneumonia. This study aims to explore a completely novel research area linking the extent of DNA methylation in blood leukocyte (monocytes and neutrophils) and function of gut and respiratory microbiota on the influence of innate immune responses to and host defense against CAP
