Active clinical trials for "Acute Lung Injury"

The outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been declared a public health emergency of international concern. Hospitalized COVID-19-positive patients requiring ICU care is increasing along with the course of epidemic. A large number of these patients developed acute respiratory distress syndrome (ARDS) according to current data. However, the related hemodynamic characteristic has so far been rarely described.

In addition to respiratory involvement, SARS-CoV 2, the virus responsible for coronavirus 2019 or Covid-19, appears to be responsible for renal involvement such as acute renal failure or proteinuria, so the mechanisms are not known at this time. The consequences of Covid-19 on renal function in the short and long term are not known. It is important to be able to better document these renal impairments to understand the mechanisms of this disease. The main objective of this study is to describe the prevalence of Covid-19-related renal damage (acute renal failure, proteinuria, microalbuminuria, hematuria) in a large cohort of patients in intensive care for SARS-CoV 2 infection with severe respiratory impairment. The other objectives will be to evaluate in this cohort the impact of these renal impairments on the severity of the Covid-19 disease, and to compare them to the renal impairments of patients in intensive care for acute respiratory distress syndrome (ARDS) due to other respiratory diseases. Blood and urine samples will be taken at the time of intubation in all critically ill patients with respiratory distress requiring mechanical ventilation for Covid-19 or other cause of respiratory distress with PaO2/FiO2 ratio < 300. Patients will be followed for the duration of their ICU and hospital stay. Data will be collected prospectively in three ICUs in the University Hospitals of Marseille.

In this study gas-exchange and respiratory mechanics variations to PEEP change will be correlated to CT lung morphological modifications assessed at different airway pressures (5, 15, 30 and 45 cmH2O).

Fibrocyte is a monocyte sub-population involved in fibroproliferation/repair processes and associated with outcome in different diseases. In previous study, we have demonstrated the presence of alveolar fibrocytes during Acute expiratory Distress Syndrome (ARDS) and their association with patient outcome. The purpose of this multicentric observational prospective study is to describe the percentage of alveolar fibrocytes in ICU patients with ARDS (survivors vs. non survivors) and to confirm their association with 28-day mortality.

The objective of the study is to determine the correlation between the physiological variables and the degree of consolidation in lung computed tomography in patients with acute respiratory distress syndrome

Hypothesis of the study is that patients undergoing major cardiac surgery can develop extracardiac complications correlated to cardiopulmonary by pass.

The purpose of this study is to examine changes in ventilation and airway pressures during conventional bronchoscopy of intubated patients.

The ARDS has a clinical definition with criteria of the American-European Consensus Conference (1994). This definition inconveniently applies to a lot of patients with acute respiratory failure. We know that there are 2 forms of ARDS morphology on CT scan : "lobar attenuation" (loss of aeration with no concomitant excess in lung tissue) predominating in the lower lobes and "non lobar attenuation" with diffuse and massive loss of aeration with excess lung tissue in all the pulmonary parenchyma. Today, plasmatic biomarkers are used as prognostic and diagnostic markers of ARDS. Some of them are characteristics of the different damages in the ARDS (alveolar epithelium and vascular endothelium lesions) : sRAGE, SP-D, PAI 1 and sICAM 1. This study's hypothesis is that patients with ARDS criteria and lobar morphology on CT scan present loss of aeration but no inflammatory pulmonary oedema, whereas patients with non lobar morphology on CT scan present both characteristics. The primary purpose of our protocol is to show that the patients who respond to ARDS criteria and have a lobar morphology on CT scan do not have an elevation of the biomarkers specific to the pulmonary aggression of ARDS.

PISA is an ancillary study to the NIH funded clinical RESTORE Trial (U01 HL086622). This study will provide data that may allow for improved dosing recommendations in this critically ill population of children.

Acute lung injury in children is a syndrome of rapid onset of acute respiratory failure and require admission into intensive care units (ICU) for advanced life support. There are almost no information on epidemiology of acute lung injury. Published studies do not have information for an entire year and none of them have evaluated the degree of oxygenation failure under standard ventilator settings. The investigators will perform a 1-year prospective audit of all patients admitted with acute lung injury in a network of pediatric ICUs in Spain.
