Active clinical trials for "Acute Lung Injury"

Efforts to identify circulating factors that predict severity of acute lung injury/acute respiratory distress syndrome（ALI/ARDS）patients is unrevealing. The primary purpose of this study is to verify circRNAs and microRNAs might be potential novel ALI/ARDS biomarkers and could play roles in pathogenesis of ALI/ARDS.

Venovenous extracorporeal membrane oxygenation (VV-ECMO) is widely used in the salvage treatment of critical acute respiratory distress syndrome (ARDS). However, reducing lung injury, accelerating lung recovery, shortening VV-ECMO support time, and decreasing complications during the treatment need further study. By changing the body position of ARDS patients, the prone position can increase the lung's dorsal ventilation and improve the lung's ventilation/blood flow ratio to improve oxygenation. Previous multicenter studies have proved that the prone position can significantly reduce the mortality of patients with moderate and severe ARDS. However, patients with severe ARDS rescue by VV-ECMO rarely combine with a prone position.On the one hand, with the support of ECMO, the patient's oxygenation will be significantly improved, and they will no longer need the assistance of a prone position. In addition, the ECMO cannula brings some challenges to implementing a prone position. Only a few cohort studies have reported that VV-ECMO combined with a prone position could improve the oxygenation index and respiratory system compliance during the late treatment period. The initial reason for PP in ARDS patients was to alleviate severe hypoxemia, as it was an efficient means to improve oxygenation in most patients. However, some patients were categorized as non-responders in the PP regarding oxygenation, which caused VV-ECMO therapy to be initiated. Should we decide to perform PP after VV-ECMO therapy no longer? This study evaluates whether early use of PP during VV-ECMO would increase the proportion of patients successfully weaned from VV-ECMO support compared with supine positioning in severe ARDS patients who received PP before ECMO.

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.

The study aims to investigate organ dysfunction and biomarkers in patients with suspected or verified COVID-19 during intensive care at Uppsala University Hospital.

The data were retrospectively collected during the first and the second wave of epidemic in COVID-19 patients with Severe Acute Respiratory Syndrome Coronavirus 2, at the moment of intensive care unit admission and during the in intensive care unit staying.

In this study, the investigators aim to better characterize the outcomes of pediatric acute respiratory distress syndrome (PARDS) survivors, to examine whether subgroups of children with PARDS can be identified, and to determine whether an earlier diagnosis of PARDS using a computerized decision support system will improve the care of these children.

The overall goal of the study is to risk stratify pediatric Acute Respiratory Distress Syndrome (ARDS) patients and to identify sub-phenotypes with shared biology in order to appropriately target therapies in future trials. This is a prospective, multicenter study of 500 intubated children with ARDS, with planned blood collection within 24 hours of ARDS onset and subsequent measurement of plasma protein biomarkers and peripheral blood gene expression.

The exosomes in the experimental group and the control group were sequenced to find the difference of the two groups, providing a basis for subsequent basic research.

Acute Respiratory distress syndrome (ARDS) is a severe condition in which protective ventilation is a critical point in its management. Positive end expiratory pressure (PEEP) setting can be challenging for clinicians and high PEEP has been associated with better outcome in moderate and severe ARDS. Recently, recruitment to inflation ratio and airway closure have been investigated in order to help PEEP adjustment. However, ventilatory maneuvers are performed with a low level of PEEP and therefore expose to derecruitment and oxygen desaturation. So far, the risk of oxygen desaturation has not been investigated and risk factors are unknown. The aim of this study is to evaluate the prevalence of oxygen desaturation during ventilatory maneuvers at low level of PEEP in patients with moderate or severe ARDS

Respiratory failure associated with Covid-19 can be expressed as acute respiratory distress syndrome (ARDS), which is an acute inflammatory lung injury,which generally requires the use of invasive mechanical ventilation (MV). There are inconclusive results regarding the potential lung recruitment in ARDS. Recently, a new index based on lung compliance has been described to directly quantify the potential for lung recruitment, called the recruitment-inflation index (R/I index). The objective of this study is to prospectively evaluate the recruitment capacity in patients with ARDS and ARDS-Covid-19.
