Filter by:Transfusion-related acute lung injury (TRALI) is a severe complication of blood transfusions. After a transfusion, TRALI develops in 0.08-15% of cases. The incidence of TRALI is 50-100 times higher in critically ill patients compared to the general hospital population. No biomarkers are yet known to detect TRALI. This study will compare blood samples of TRALI patients with blood samples of intensive care patients in order to find possible biomarkers for TRALI.
This is a multicenter international observational prospective cohort study. The main questions it aims to answer are: - PRIMARY AIM: To describe the capability of IRVF demodulation at diagnosis of ARDS to predict development of AKI within 7 days from the ARDS onset - SECONDARY AIMS: A)Describe the capability of IRVF demodulation or pattern of IRVF (continuous, pulsatility, biphasic, monophasic) to predict development of AKI within 14 days from the ARDS onset. B) To describe the RD parameters and VexUS in the AKI and no AKI patients over time. C) Describe the impact of invasive mechanical ventilation (IMV) on the intrarenal venous congestion and VexUS., D) Evaluation of effect of CRRT on IRVF pattern, VexUS and parameters. E) Describe the feasibility of renal doppler to assess IRVF in critically ill respiratory patients. F) Evaluate the incidence of AKD and CKD Participants will Adult patients with diagnosis of ARDS admitted to intensive care unit and undergoing invasive mechanical ventilation
The aim of the study is to see if endogenous exhaled Nitric Oxyde (eNO) concentrations measured are significantly higher in ARDS patients admitted in ICU ; compared to control subjects in good health with no lung disease or global inflammation, operated under general anesthesia (i.e. intubated and ventilated) for thyroid or parathyroid.
Investigation of the feasibility of monitoring processed transcutaneous electroencephalography (EEG), a method of interpreting brain activity, and near-infrared spectroscopy (NIRS), a method of determining levels of tissue oxygenation (StO2) in the brain, for patients with acute respiratory distress syndrome (ARDS) in the ICU.
In some ARDS patients, a mild chest compression (5 kg) improves lung compliance. We aim to determine wether such an improvement is due to a better recruitment or to a reduction of overdistension
The adequate characterization of RV injury is currently unknown. The hypothesis is that the best characterization of RV injury is the one with the most significant impact on the response to fluids and on the outcome. An RV failure is expected to induce fluid-unresponsiveness and potentially worst outcome. The main objective is to characterize different types of RV injury in critically ill patients by examining their association, including predictive performances, in hemodynamics parameters, ventilation parameters, and clinical outcomes The study will be based on the realisation of an echocardiography within 48 hours following inclusion.
Allogeneic culture-expanded bone marrow-derived human mesenchymal stem cells (MSC) are the subject of the current study as they are supported by preclinical and clinical data for potential to provide a safe and effective treatment for patients with acute respiratory distress.
Acute respiratory distress syndrome (ARDS) is a lesional pulmonary edema that occurs as a result of direct or indirect lung injury. This condition accounts for 10-15% of ICU admissions and 20-25% of patients admitted require invasive ventilation. Its incidence has increased markedly with the Covid-19 epidemic. ARDS is defined as hypoxemia (Pa02/Fi02 < 300 mmHg) in ventilated patients without heart failure. Currently, the recommendations of the resuscitation societies advocate a management combining invasive ventilation, short duration curarization and prone sessions. In case of failure of these therapies, venovenous ExtraCorporeal Membrane Oxygenation (VV ECMO) is recommended in case of Pa02/Fi02 < 80 mmHg. Nevertheless, approximately 40% of patients have refractory and persistent hypoxemia despite optimization of ECMO parameters and invasive ventilation. The refractory hypoxemia is defined as Pa02 < 55 mmHg and/or Sa02 < 90% and may be due to a recirculation phenomenon or a significant intra-pulmonary shunt. Currently, there is no official recommendation for the management of these patients, leading to the use of various unvalidated field practices. In addition, hospital mortality of the order of 60% is observed in these patients with high management costs. Some data in the literature suggest that induced therapeutic hypothermia (HT) at 34°C for 48 hours could improve the prognosis of these patients by improving oxygenation. Nevertheless, the level of evidence of published studies remains low because they are either case reviews or studies whose methodology does not guarantee the absence of potential bias. The research hypothesis is that HT at 34°C or 33°C for 48 hours is effective on refractory hypoxemia.
To evaluate the safety and efficacy of intravenous(IV) administration of bone marrow mesenchymal stem cell derived extracellular vesicles(EV), ExoFlo, as treatment for Acute Respiratory Distress Syndrome.
The acute respiratory distress syndrome (ARDS) remains a common and morbid complication of critical illness. Sepsis contribute to a lot of ARDS cases, but mechanisms by which non-pulmonary insults such as extrapulmonary sepsis propagate lung injury remain unclear. Most eukaryotic cells release small anuclear membrane-bound vesicles into the extracellular environment in either physiological or pathophysiological conditions, often called extracellular vesicles (EVs) .Through their cargo containing bioactive molecules such as proteins, mRNAs, and microRNAs and their interaction with target cells, EVs are recognized as important mediators of cellular communication. Mitochondrial contents are clearly present in EVs, and mitochondrial cargo within EVs have been shown to stimulate the production of proinflammatory cytokines, further enhancing LPS-induced inflammation. Among the mitochondrial contents, mtDNA was present at higher levels in EVs.Therefore, we hypothesis, EVs containing mtDNA play an important role in the occurrence and development of ARDS caused by extrapulmonary sepsis.
