Epidemiology and Prognosis of ARDS After Pulmonary Resection Surgery

The improvement in ARDS mortality over the last 20 years seems to be largely explained by the reduction of mechanical ventilation-induced injury (VILI). VILI is essentially related to volotrauma closely associated with "strain" and "stress". The pulmonary stress corresponds to the transpulmonary pressure (alveolar pressure - pleural pressure), and the strain to the change in lung volume related to the functional residual capacity (FRC) of the injured lung at PEEP = 0. The volotrauma corresponds therefore to the generalized excess of stress and strain on the injured lung. The initial therapeutic strategy consists in protective ventilation with a tidal volume of 6 ml/kg of theoretical ideal weight (predicted by height), associated with a high respiratory rate between 25 and 30 cycles per minute to control PaCO2 (< 50 mmHg), apply a high positive expiratory pressure PEEP according to FiO2, maintain a plateau pressure (PP) lower than 30 cmH20, reduce instrumental dead space, use curarization, recruitment maneuvers such as alternate prone, improve ventilation-perfusion adequacy using inhaled NO. As a last resort, extracorporeal oxygenation by veno-venous ECMO is a device to supplement respiratory function by improving oxygenation and ensuring decarboxylation. Veno-venous ECMO is indicated in severe ARDS with PaO2/FiO2 < 80 mmHg and/or when mechanical ventilation becomes unsafe due to increased plateau pressure despite optimized ARDS management including high PEEP levels, curarization and prone position. After lung resection surgery, the incidence of ARDS is 2-8% and its prognosis remains more poor, despite advances in management, with a mortality of up to 60%. Risk factors include intraoperative vascular filling, type of pulmonary resection, and predicted postoperative respiratory function. Early support with VV ECMO is vital in some patients to treat severe hypoxemia, due to variable surgical reduction of lung parenchyma depending on carcinological involvement or initial lung pathology. ). There are very few data concerning these patients with pulmonary resection. The primary objective of this study is to describe the prevalence of ARDS and the risk factors for its occurrence after pulmonary resection surgery. The secondary objective is to compare the ventilation parameters (especially motor pressure) in patients with reduced lung parenchyma in ARDS under VV ECMO with those who did not use VV ECMO assistance.

Intravenous Imatinib in Mechanically Ventilated COVID-19 Patients

The SARS-CoV2 pandemic and resulting COVID-19 infection has led to a large increase in the number of patients with acute respiratory distress syndrome (ARDS). ARDS is a severe, life-threatening medical condition characterised by inflammation and fluid in the lungs. There is no proven therapy to reduce fluid leak, also known as pulmonary oedema, in ARDS. However, recent studies have discovered that imatinib strengthens the cell barrier and prevents fluid leak in the lungs in inflammatory conditions, while leaving the immune response intact. The investigators hypothesize that imatinib limits pulmonary oedema observed in ARDS due to COVID-19, and may thus help to reverse hypoxemic respiratory failure and to hasten recovery. The hypothesis will be tested by conducting a randomised, double-blind, parallel-group, placebo-controlled multi-centre clinical study of intravenous imatinib in 90 mechanically-ventilated, adult subjects with COVID-19-related ARDS. Study participants will receive the study drug (imatinib or placebo) twice daily for a period of 7 days. The effect of the intervention will be tested by measuring extravascular lung water (i.e. pulmonary oedema) difference between day 1 and day 4, using a PiCCO catheter (= pulse contour cardiac monitoring device). Other measurements will include regular blood tests to investigate the safety and the pharmacokinetic properties of imatinib, as well as biomarkers of inflammation and cellular dysfunction. Furthermore, parameters of ventilation and morbidity and mortality will be recorded as secondary outcome measures.

High Dose Vitamin-D Substitution in Patients With COVID-19: a Randomized Controlled, Multi Center Study

The world is currently facing a pandemic with the coronavirus (SARS-CoV-2) which leads to the disease of COVID-19. Risk factors for a poor outcome of COVID-19 have so far been identified as older age and co-morbidity including chronic respiratory conditions such as chronic obstructive pulmonary disease (COPD) and current smoking status. Previous studies found, that vitamin D deficiency is more prevalent among patients with these risk factors. There are observational studies reporting independent associations between low serum concentrations of 25-hydroxyvitamin D (the major circulating vitamin D metabolite) and susceptibility to acute respiratory tract infection. Vitamin D substitution in patients with COVID-19 who show a vitamin D deficiency should therefore be investigated for efficacy and safety. The study is designed as a randomized, placebo-controlled, double blind study. The objective of the study is to test the hypothesis that patients with vitamin D deficiency suffering from COVID-19 treated under standardized conditions in hospital will recover faster when additionally treated with a single high dose of vitamin D compared to standard treatment only.

PRONing to Facilitate Weaning From ECMO in Patients With Refractory Acute Respiratory Distress Syndrome

ECMO has emerged as a promising intervention that may provide more efficacious supportive care to patients with refractory severe acute respiratory distress syndrome (ARDS). The largest randomized trial of ECMO for severe forms of ARDS was recently published and demonstrated no significant benefit from early initiation of ECMO with respect to 60-day mortality, when compared with a strategy of conventional mechanical ventilation (MV) (ref EOLIA). However, a rescue ECMO option was used by 28% of the controls, which is likely to have diluted the potential positive effect of ECMO. One may argue that a less restrictive primary endpoint, such as death or rescue ECMO, would have yielded positive findings. Meanwhile, improvements in technology have made ECMO safer and easier to use, allowing for the potential of more widespread application in patients with ARDS. VV-ECMO can be used as a life-saving rescue therapy in patients with ARDS when MV cannot maintain adequate oxygenation or CO2 elimination. Alternatively, VV-ECMO may be used in patients who remain hypoxemic during MV (i.e., PaO2/FiO2<80 mmHg) despite optimization of MV (including the application of high levels of positive end-expiratory pressure (PEEP), neuromuscular blockers, and prone positioning) and allow "lung rest" by lowering airway pressures and tidal volume to ameliorate ventilator-induced lung injury (VILI). Prone positioning (PP) has been used for more than 30 years in patients with acute hypoxemic respiratory failure and in particular with ARDS. Initially, PP in ARDS patients was proposed as an efficient mean to improve oxygenation, sometimes dramatically, in a large number of patients. In addition, it is now clear, and data are still accumulating, that PP is also able to prevent VILI which is as important as maintaining safe gas exchange in mechanical ventilation. Therefore, PP is a strategy that covers the two major goals of ventilator support in ARDS patients, maintaining safe oxygenation and preventing VILI and reducing mortality at the end. This latter objective makes sense on ECMO as one of the main objective of this device is to markedly reduce VILI by resting the lung. Considering that PP is a valuable and safe therapy to reduce VILI, its combination with ECMO could enhance VILI prevention. In recent preliminary studies, it was reported that the combination of VV-ECMO and PP was associated with a dramatic improvement in oxygenation, in pulmonary and thoracic compliance and in chest X-ray findings. It may thus facilitate the weaning of ECMO and can be performed without compromising the safety of the patients. Lung recruitment and improvement in ventilation/perfusion mismatch on prone position may both contribute to improve oxygenation. PP may therefore be efficient to hasten the weaning of VV-ECMO when atelectasis and ventilation/perfusion mismatch occur under ultra-protective ventilation even in patients in whom pre-ECMO PP failed. In addition, it could also enhance ventilator induced lung injury prevention on ECMO.

Clinical Decision Support Tool in PARDS Pilot Study

Previous clinical trials in adults with acute respiratory distress syndrome (ARDS) have demonstrated that ventilator management choices can improve Intensive Care Unit (ICU) mortality and shorten time on mechanical ventilation. This study seeks to scale an established Clinical Decision Support (CDS) tool to facilitate dissemination and implementation of evidence-based research in mechanical ventilation of infants and children with pediatric ARDS (PARDS). This will be accomplished by using CDS tools developed and deployed in Children's Hospital Los Angeles (CHLA) which are based on the best available pediatric evidence, and are currently being used in an NHLBI funded single center randomized controlled trial (NCT03266016, PI: Khemani). Without CDS, there is significant variability in ventilator management of PARDS patients both between and within Pediatric ICUs (PICUs), but clinicians are willing to accept CDS recommendations. The CDS tool will be deployed in multiple PICUs, targeting enrollment of up to 180 children with PARDS. Study hypotheses: The CDS tool in will be implementable in nearly all participating sites There will be > 80% compliance with CDS recommendations and The investigators can implement automatic data capture and entry in many of the ICUs Once feasibility of this CDS tool is demonstrated, a multi-center validation study will be designed, which seeks to determine whether the CDS can result in a significant reduction in length of mechanical ventilation (LMV).
