Neutrophil Elastase Inhibitor in Treatment of ARDS Patients With Mechanical Ventilation Caused by...
Acute Respiratory Distress SyndromeSepsis is a life-threatening organ dysfunction caused by the host's maladjusted response to infection. It is one of the common clinical critical diseases, often accompanied by multiple organ failure, immune imbalance and high mortality. Sepsis is a syndrome of physiological, pathological and biochemical abnormalities caused by infection. Its incidence rate and prevalence have been on the rise in the past few years. Sepsis has greatly endangered the lives and health of the public. Among them, ARDS is a fatal complication of sepsis and a common critical illness syndrome in ICU. At present, the conventional treatment for ARDS caused by sepsis is still limited to indirect supportive therapy such as primary disease treatment, infection control, mechanical ventilation support, and nutrition improvement, lacking specific direct treatment methods. So far, the drug treatment effect of ARDS at home and abroad is not satisfactory. Therefore, it has become an urgent task to find a new treatment strategy to alleviate ARDS. Neutrophil elastase inhibitors can reversibly and competitively inhibit the release of neutrophil elastase, inhibit the activation of neutrophils and the infiltration of inflammatory cells in the lungs, alleviate the release of inflammatory mediators, and thus improve respiratory function, which has a good protective effect on various experimental ARDS. However, the efficacy of neutrophil elastase inhibitor represented by sivelestat sodium in the treatment of ARDS has reached a relatively consistent positive conclusion in animal experiments, while the results of clinical studies are different. These differences in clinical research still need further analysis, research and verification in clinical trials. At present, the clinical studies of neutrophil elastase inhibitors in the treatment of sepsis induced ARDS are very few, and there is a lack of related prospective randomized controlled clinical studies. Therefore, further prospective clinical trials are needed to evaluate the therapeutic effect of neutrophil elastase inhibitors on sepsis induced ARDS patients. This study is intended to determine whether neutrophil elastase inhibitor can reduce the mechanical ventilation time, Murray lung injury score, ICU hospitalization time and 28-day mortality of septic ARDS patients compared with the control group through a single center randomized controlled trial, so as to provide a new basis for the treatment strategy of septic ARDS patients.

Evaluating Pressures During Non-invasive Ventilation Utilizing NIV Plus Software
Respiratory Distress SyndromeNewborn1 moreIn the past many neonates with respiratory distress syndrome would require intubation, but over the years these rates have declined as the capabilities of non-invasive ventilation (NIV) have vastly improved. Despite these improvements, the decrease in pressure transmission due to factors such as resistance from tubing or air leaks around the nostrils and mouth, continues to be one of the major drawbacks when using nasal NIV. Current ventilators measure the set pressures at the circuit but do not capture the delivered pressure at the patient's nares. Recently, Medtronic PB980 ventilators feature NIV plus and leak sync software that can be calibrated to measure the pressures provided at the nostrils. Optimum pressures received at the nostrils to provide safe and effective therapy in neonates is currently unknown. In the prospective portion of the study, we aim to evaluate safety and efficacy of the software by comparing the average pressure difference between the circuit and delivery pressure at the nares, the incidence of apnea, bradycardia, desaturations as well as escalation and de-escalation of ventilator support in newborns who are receiving NIV admitted to NICU

Explore Potential Plasma and BALF Immunometabolic and Lipidomic Biomarkers for Identifying ARDS...
Acute Respiratory Distress SyndromeAcute Respiratory FailureAcute respiratory distress syndrome (ARDS) is a life-threatening condition that causes high mortality (41% to 58%). Previous studies have reported that biomarkers can facilitate phenotypic diagnosis of ARDS, enabling precision treatment of ARDS. Although there were many studies that found some potential therapeutic targets for ARDS, no pharmacotherapies have been validated to treat ARDS. The development of biomarkers to predict the prognosis and monitor the response to treatment would be of interest for selecting patients for specific therapeutic trials. Many recent studies have shown that immune metabolic changes are involved in the pathogenesis of ARDS and may become a new therapeutic target for them. We aimed to identify a panel of immunometabolic and lipidomic biomarkers derived from blood and bronchoalveolar lavage fluid (BALF) which may help differentiate the ARDS endotypes.
Pressure Opening With Electrical Impedance Tomography
Acute Respiratory Distress SyndromeAcute Lung InjuryAcute lung injury and ARDS (acute respiratory distress syndrome) are characterized by lung inhomogeneity, leading to a different distribution of the tidal volume (and pressure) within the lung. The quasi-static PV curve is a useful bedside tool to set mechanical ventilation, but it reflects a global behaviour of the lung. The electrical impedance tomography (EIT) is a non-invasive and radiation-free tool, monitoring dynamic changes in gas distribution. Images from EIT can be divided in several regions of interest, allowing to measure regional changes in compliance. The regional derived-EIT PV curve could provide valuable information on airway closure and AOP (airway opening pressure). Recent studies suggest that AOP measured by the ventilator seems to correspond to the AOP of the lowest injured lung. The investigators will perform one pressure-volume (PV) curve with a low-flow insufflation of 5 L/min starting from 0 cmH2O to a maximal airway pressure corresponding to the plateau pressure. During the low-flow insufflation, both ventilator and EIT-derived PV curves will be recorded. All PV curves will be analysed offline by the investigator to detect complete and regional airway closures, and measure AOPs.

Use of hUC-MSC Product (BX-U001) for the Treatment of COVID-19 With ARDS
COVID-19ARDS1 moreThis is a phase 1/2a study including 2 parts, phase 1 and phase 2a. The phase 1 part is an open-label, single-arm, dose-escalating study to evaluate the safety and explore the dose limiting toxicity and maximum tolerated dose of a human umbilical cord derived mesenchymal stem cell product (BX-U001) in severe COVID-19 pneumonia patients with acute respiratory distress syndrome (ARDS). Qualified subjects after the screening will be divided into low, medium, or high dose groups to receive a single intravenous infusion of BX-U001 at the dose of 0.5×10^6, 1.0×10^6, or 1.5×10^6 cells/kg of body weight, respectively. The Phase 2a part is a randomized, placebo-controlled, double-blind clinical trial examining the safety and biological effects of BX-U001 at the appropriate dose selected from phase 1 for severe COVID-19 pneumonia patients with the same inclusion/exclusion criteria as the phase 1 part.
Using TEE to Evaluate the Effect of Levosimendan on Patients With ARDS Associated With RVD During...
Transesophageal EchocardiographyAcute Respiratory Distress Syndrome1 moreAcute respiratory distress syndrome (ARDS) is often complicated by right ventricular dysfunction (RVD), Acute cor pulmonale is the most serious form of ARDS complicated with RVD.Levosimendan is indicated for short-term treatment of acute decompensated heart failure that is not responding well to conventional therapy and requires increased myocardial contractile force.In 2016, the European Society of Cardiology issued recommendations for the management of acute right heart failure, stating that levosimendan can improve right ventriculo-pulmonary artery coupling by both increasing right heart contractility and reducing pulmonary vascular resistance.However, the clinical application of levosimendan in the treatment of ARDS right heart dysfunction is insufficient.Therefore, this study intends to use transesophageal ultrasound to evaluate right ventricular function, reduce the limitation of poor right ventricular window in transthoracic echocardiography, and conduct a multi-center randomized controlled study to further explore the effects of levosimendan on right ventricular function in ARDS patients, such as tricuspid ring systolic displacement (TAPSE) and tricuspid ring systolic displacement velocity (S '). Effects of right ventricular area change fraction (RV FAC), right ventricular end-diastolic area/left ventricular end-diastolic area (RVEDA/LVEDA), pulmonary circulation resistance (PVR), hemodynamics and mortality.
