Active clinical trials for "Acute Lung Injury"

To carry out a prospective cohort study of healthy volunteers, assessing differences between baseline pulmonary inflammation, response to LPS inhalation and endothelial function, as measured by flow mediated dilation between, electronic cigarette uses, cigarette smokers and non smokers.

Fluid responsiveness (FR)refers to the ability of heart to increase its stroke volume in response to volume load.Low tidal volume and high PEEP exerts contrast effect on the prediction of fluid responsiveness, the aim of this study is to compare the relative predicting power of the dynamic preload indicator (PPV, SVV), passive leg raising test, and pleth variability index (PVI) on the fluid responsiveness of acute respiratory distress syndrome ventilated with various PEEP levels or various tidal volumes.

Get a better understanding of the pathophysiological processes of acute respiratory failure following cardiopulmonary bypass to initiate timely therapies targeted on a cell line. Demonstrate that there is a relationship between increased transpulmonary gradients of inflammation biomarkers (sRAGE, sICAM-1, SPB, PAI-1, ROS) and pulmonary vascular resistance on the one hand and alveolo-capillary gas exchange on the other hand after cardiac surgery under cardiopulmonary bypass.

A prospective, 2-arm, single-blind, randomized controlled clinical feasibility trial design is planned. Forty CCI survivors will be randomized (1:1) to either the PS-PICS (peer support) intervention or usual care (control) group.

The investigators established a national cohort of Chinese ARDS with Acute CorPulmonale to enable prospective observational studies. The goals are the following. First, morbidity and mortality rate of ARDS with ACP in the ICU across Chinese mainland. Second, forming the diagnostic ultrasound strategy of ARDS-ACP, namely TRIP procedures. And predictive value of diagnostic strategy for ACP or prognosis of ACP were calculated. Third, comparison of ventilator parameters for ACP and non-ACP or survivor and non-survisors, which reaveald that of inappropriate mechanical ventilation on circulation and prognosis. Screening for risk factors of ARDS with ACP.

The acute respiratory distress syndrome (ARDS) is a severe form of respiratory failure with a mortality rate of approximately 40%. Despite advances in its supportive treatment such as lung protective ventilation or restrictive fluid management, no effective pharmacotherapy exists to treat ARDS. Emerging preclinical data indicates that excessive activation of the inflammasome-Caspase 1 pathway plays a key role in the development of ARDS. Tetracycline has anti-inflammatory properties via inhibiting inflammasome-caspase-1 activation. Since not much is known about the activation of the inflammasome in clinical ARDS, the purpose of this study is i) to investigate the the inflammasome-caspase-1 activation in clinical ARDS and ii) inhibit the innate immune response of alveolar leucocytes obtained by tetracycline from patients with ARDS

In this prospective study of 60patients, we tested the hypothesis That markedly elevated levels of plasma von Willebrand factor (VWF) a marker of endothelial cell injury might predict the development of acute respiratory distress syndrome (A.R.D.S) in risky patients. We compared our result to IL.6 as control biomarker for A.R.D.S development. Acute lung injury was quantified on two -point scoring system (Berlin definition of ARDS and Murray score of acute lung injury). Plasma levels of both vWF and IL.6 were be measured on T=0 i.e. (at start of the study once the patient considered to be risky for A.R.D.S development to obtain their baseline levels), T=48 (after 48 hours), and T=72 (after 72 hours).

Shock is one of the five leading causes of income and mortality in emergencies. It generates a decrease in the availability of oxygen to the tissues, resulting in ischemia, pulmonary involvement and tissue reperfusion syndrome. This pathologies can trigger Syndrome of Acute Respiratory Distress (ARDS) and death. Troponin I (TI) has been reported as early marker for ischemia and mortality other than coronary syndromes in critical patients. Objective. Set the increase of TI as a predictor of ARDS in children with shock. Null hypothesis. Increase serum in children with shock predicts the onset of ARDS. Methodology. Prospective cohort type test diagnostic. Displays institutional. Sampling non-probability, consecutive inclusion. Calculation of the sample size: interval of confidence (IC) 95%, power - 80%; ratio non-exposed: exposed 2:1; n = 62. Inclusion criteria: informed consent signed by the parent; children admitted to pediatric emergency (PEU) 1 month to 14 years with shock requiring mechanical ventilation. Exclusion criteria: intake of toxic (TI value increment per will), ≥3 concentrated erythrocyte transfusion or plasma prior to entering PEU. The investigators call exposure to the increase of TI≥0 05ng/ml and event to the development of ARDS. Determine TI value in plasma serum in the first 24 h, through Enzyme Immunoassay for the Quantitative Determination of Cardiac-Specific Troponin-I in Human Serum (cTnI ELISA), (reported as cardiac triage). Monitoring for 7 days. Study was approved by Hospital Ethics Committee (Research record 003/12)

The purpose of the DACAPO study ("Surviving ARDS: the influence of quality of care and individual patient characteristics on quality of life") is to investigate the role of quality of care and individual patient characteristics on quality of life and return to work in survivors of ARDS (acute respiratory distress syndrome). It is hypothesized that higher quality of care is associated with better health-related quality of life and a higher rate of return to work among survivors. A prospective, observational, multi-centre patient cohort study is performed in Germany, using hospitals from the "ARDS Network Germany" as the main recruiting centres. It is envisaged to recruit 2400 patients into the DACAPO study and to analyze a study population of 1500 survivors. They will be followed up until 12 months after discharge from hospital. Quality of care will be assessed as process quality, structural quality and volume at the institutional level. The main outcomes (health related quality of life and return to work) will be gathered by self-report questionnaires. Further data assessment includes general medical and ARDS-related characteristics of patients as well as sociodemographic and psycho-social parameters. Multilevel hierarchical modelling will be performed to analyse the effects of quality of care and individual patient characteristics on outcomes, taking the cluster structure of the data into account.

Acute lung injury is a highly prevalent disease in children, posing a serious threat to their health and causing economic burden on society and families. It has received high attention. Blocking the cascade immune inflammatory response that occurs in the respiratory tract and finding key targets for the prevention and treatment of acute lung injury has become an important challenge faced by the medical community. The pathogenesis of acute lung injury is complex, involving the combined action of multiple cells and cytokines in the immune system. Therefore, it is necessary to further study the function of immune cells and specific immune pathogenesis, providing new ideas and theoretical basis for clinical treatment of acute lung injury. The omics technology includes Genomics, Transcriptome, proteomics, metabolomics, etc. Through qualitative and quantitative analysis of changes in low molecular weight molecules or metabolites of biological samples, it provides a new way to find biomarkers and pathogenesis. We plan to study the peripheral blood of children with acute lung injury and healthy children, and use network analysis to screen for differential genes and related enrichment pathways in acute lung injury. We aim to explore the correlation between immune regulation and inflammatory repair in children with acute lung injury, and analyze the regulatory mechanisms between immune cells related to it. Provide assistance for clinical diagnosis and treatment.
