Active clinical trials for "Acute Lung Injury"

Covid-19 also primarily affects endothelium that line up the alveoli. The resulting hypoxemia may differ from "typical" Acute Respiratory Distress Syndrome (ARDS) due to maldistribution of perfusion related to the ventilation. Thus, pathophysiology of Covid-19 ARDS is different, which requires different interventions than typical ARDS. The investigators will assess whether extravascular lung water index and permeability of the alveolar capillary differs from typical ARDS with transpulmonary thermodilution (TPTD) technique. Extravascular Lung Water Index (EVLWI) and Pulmonary Vascular Permeability Index (PVPI) will be compared.

Understanding the role VEGF plays in ARDS consequently provides an ideal opportunity to discover new therapies for ARDS.

This expanded access protocol will provide access to the investigational product Zofin for patients in outpatient facilities infected with SARS-CoV-2 who have mild to moderate COVID-19, or who are judged by a healthcare provider to be at high risk of progression to moderate disease.

The optimal amount caloric intake were still controversy in critically ill patients in literature. There were no significant outcome difference with different caloric intake in acute lung injury patients. In order to identify the optimal amount caloric intake in acute lung injury patients, we conduct a prospectively observational study to see whether the caloric differences influence hospital mortality.

Renal damage in patients hospitalized for ARDS in the ICU can also be related to multiple causes including, but not limited to, the consequences of hemodynamic fluctuations in these patients or the use of nephrotoxic drugs responsible for acute post-ischemic or toxic tubular necrosis. Frequently observed abnormalities of cioagumation may also have a potential impact on renal structures, particularly glomerular capillaries. The researchers wish to characterize and phenotype the renal impairment of patients hospitalized in intensive care with tables of severe Covid19 infections in ARDS: clinical, biological and histological (by performing post-mortem biopsies).

Pandemic SARS-CoV-2 (COVID-19) respiratory infection is responsible for more than 4,000 deaths, mainly (67%) secondary to acute respiratory distress syndromes (ARDS). ARDS is usually associated with a mortality of around 40%, but this rate reaches 61% in patients infected with SARS-CoV-2. Two endotypes have been described in patients with ARDS: one, hyper-inflammatory, associated with very high mortality (51%); the second, slightly inflammatory (immunoparalysis), associated with much lower mortality (19%). In COVID-19 patients, distinct immune response profiles have also been observed. Some patients present deep lymphopenia and/or prolonged viral excretions associated with more frequent occurrence of co-infections (+ 29% of virus, + 23% of bacteria, + 10% of fungi). The latter group may be at higher risk in terms of mortality. The intensity of the inflammatory response and/or microbial coinfections therefore appear as risk factors for severity and mortality in patients infected with SARS-CoV-2 which determine the course of the disease. To adapt early optimal therapeutic management to each forms of the disease, it is essential to be able to characterize these profiles on the microbiological and inflammatory level. With a committed network of 6 intensive-care units across eastern and northern Ile-de-France, 180 patients with ARDS and infected with SARS-CoV-2 are being enrolled. For these patients, a nasopharyngeal swab is collected at inclusion; followed by a new nasopharyngeal swab and a deep respiratory sample once a week, until D28, for an exploration of co-infections and for monitoring the viral load of SARS-CoV-2. The rest of each of these samples are collected for the study. In parallel, the clinical data usually collected in the context of intensive care will be collected on a CRF. They will allow to calculate risk scores such as SOFA.

Sepsis is the most frequent risk factor for ALI/ARDS. Meanwhile, Pulmonary is the most vulnerable organ to fail in response to sepsis, vascular endothelial dysfunction is a central event in the pathophysiology of sepsis. An improved understanding of endothelial response and associated biomarkers may lead to strategies to more accurately predict outcome and develop novel endothelium-directed therapies in sepsis. The human and mouse R-spondins encode a family of proteins that includes four paralogs (R-spo1-4). R-spondins are secreted proteins found primarily in the extracellular region and are known to promote β-catenin signaling. Among them, the embryonic lethal vascular remodeling phenotype of R-spondin3 (Rspo3) mutant mice suggests a role of EC derived Rspo3 in angiogenesis. Rspo3 protects tissues against mesenteric I/R by tightening endothelial cell junction and improving vascular intergrity. However, the role of Rspo3 in sepsis-induced pulmonary endothelial dysfunction remains unclear. Thus, it is worthwhile to explore the relationship between Rspo3 and sepsis-induced lung injury, which will be helpful for prevention and treatment of sepsis-induced lung injury and endothelial dysfunction.

The investigators propose to perform a one-year prospective audit of all Acute lung injury (ALI)and cute respiratory distress syndrome (ARDS) pediatric patients managed in several ICUs in Spain. The investigators intend to collect data from all children (from 1 month to 18 years of age) admitted with or developing ALI/ARDS with the aim to understand the epidemiology and natural history of acute lung injury in the pediatric setting. These ICUs are scattered through the Spain and are representative of the demographic differences across the country.

Identify pediatric oncologic patients with ALI/ARDS at GRAACC/IOP's Pediatric Intensive Care Unit and evaluate the mechanical ventilation practice in these subjects for a 48mo period.
