Follow-up of Covid-19 Long Term Sequelae

COVID-19 PneumoniaCOVID-19 Respiratory Infection16 more

The protocol, in accordance with the objectives of ORCHESTRA project - Work Package 2, aims at investigating the characteristics and determinants of COVID-19 long-term sequelae. This goal will be reached through the harmonization of follow-up strategies across the participating cohorts to allow a standardized collection of data on COVID-19 long-term sequelae. The result will be a platform including a set of data and biomaterials from large scale international cohorts, that will be uniformly recorded, prospectively tracked and analysed. The ultimate goal will be that of providing evidence to contribute to the optimization and improvement of the management and prevention of COVID-19 sequelae. The follow-up will be organized in multiple levels of tests, according to the capability of each cohort, and will include questionnaires to collect demographic, epidemiological and clinical data, physical examination, radiological exams and biological sampling. The long-term follow-up will also allow the assessment of long-term immunological response to SARS-CoV-2 infection and its association to the vaccination and to different treatment strategies, including monoclonal antibodies.

Post Acute Sequelae of COVID-19

Covid19Sars-CoV-2 Infection3 more

COVID-19, a novel coronavirus, has caused widespread mortality and morbidity since it emerged in 2019. There is ongoing research and growing literature describing severe acute respiratory syndrome (SARS-COV-2). There is a growing population of individuals who have recovered from acute SARS-COV-2 infection. The long-term effects of COVID-19 are unknown. There are growing reports of sequelae after acute SARS-CoV-2 not limited to fatigue, dyspnea, reactive airway disease, organizing pneumonia, pulmonary fibrosis, pulmonary hypertension, pulmonary emboli, and tracheal disease. The incidence and natural history of these findings is unstudied.

Ultra-Protective Lung Ventilation With Extracorporeal CO2 Removal for Moderate ARDS

Acute Respiratory Distress Syndrome

Acute respiratory distress syndrome (ARDS) accounts for 10% of all ICU admissions and for 23% of patients requiring mechanical ventilation (MV). Its hospital mortality remains high, ranging from 34% in mild forms up to 46% in severe cases. Positive pressure MV remains the cornerstone of management, but at the same time it can contribute to worsening and maintenance of the lung injury when excessive stress and strain is applied to the lung parenchima (so-called ventilator-induced lung injury, VILI). VILI significantly contributes to the morbidity and mortality of ARDS patients, and it has been clearly demonstrated that protective (low-volume, low-pressure) MV settings are associated with a significant survival benefit. Unfortunately, in a certain proportion of ARDS cases, it is difficult to preserve acceptable gas exchange while maintaining protective ventilation settings, due to a high ventilatory load. In these cases, extracorporeal CO2 removal (ECCO2R) can be applied to grant the application of protective or even ultra-protective mechanical ventilation settings. The main outcome of this multicenter, prospective, randomized, comparative open trial is to determine whether early ECCO2R allowing ultraprotective mechanical ventilation improves the outcomes of patients with moderate ARDS.

Improvement of Pulmonary Insufficiency After Aortic Dissection With Sivelestat Sodium

Aortic DissectionAcute Lung Injury/Acute Respiratory Distress Syndrome (ARDS)

Aortic dissection (AD) is one of the most dangerous cardiovascular emergencies, with rapid onset, rapid progression, high fatality rate, and a variety of life-threatening complications. Acute lung injury (ALI) caused by AD is an important cause of many adverse outcomes. Studies have confirmed that 34.9% to 53.8% of AAD patients have ALI before surgery, and Impaired preoperative lung function may lead to worse oxygenation after AD surgery. The pathophysiological mechanism of AD-induced ALI is complex. A variety of preoperative and intraoperative risk factors can induce or aggravate ALI, such as ischemia-reperfusion injury, deep hypothermic circulatory arrest, and inflammatory reactions. At present, the clinical use of improved surgery, cardiopulmonary bypass perfusion, early anti-inflammatory treatment, and protective lung ventilation can reduce and improve perioperative ALI to a certain extent, but it is still not ideal. In recent years, inhibition of neutrophil activation and aggregation, and reduction of neutrophil elastase activity as targets for the treatment of inflammatory injury have also become an important clinical treatment measure, in order to further reduce the body's inflammatory response to improve and alleviate ALI. Sivelestat sodium, as a neutrophil elastase inhibitor, is the only approved therapeutic drug for ALI/ acute respiratory distress syndrome (ARDS) in the world. It is precisely by reducing the inflammatory infiltration of neutrophils and inhibiting neutrophil elastase activity, thereby exerting a certain protective effect on the lungs. The study takes patients with AD surgery as the research object. On the basis of not terminating and changing the original treatment plans, sivelestat sodium was added in the perioperative period to observe the incidence, and severity of ALI/ARDS in the perioperative period. It aims to explore the efficacy and safety of sivelestat sodium in the treatment of pulmonary insufficiency after AD arch surgery under hypothermic circulatory arrest.

Acute Respiratory Distress Syndrome(ARDS) in Neonates

ARDSNRDS

Acute respiratory distress syndrome in neonates has been defined in 2015. Earlier identification and successful intervention into the potential pregnancy associated risk factors for the conversion from NRDS to ARDS is one of the most important components of ARDS prevention.

Inspiratory Ratio: Predictor of Inspiratory Effort Response to High PEEP in Patients Recovering...

Acute Respiratory Distress Syndrome

Spontaneous Breathing (SB) can be potentially harmful in patient with Acute Respiratory Distress Syndrome (ARDS) during the transition phase of passive ventilation to partial ventilatory support. The application of high Positive End Expiratory Pressure (PEEP) during SB has shown to ameliorate the progression of lung injury by decreasing the TP and esophageal pressure (EP) swings and the stress / strain applied to the lung. The mechanisms proposed to be responsible for these effects are the activation of Hering Breuer reflex, the recruitment of previously collapsed tissue, the homogenization of lung and the improvement of respiratory system compliance and the impairment in the length - tension relationship of the diaphragm. If all the previously explained mechanisms have an effect on the control of inspiratory effort, a decrease in the intensity of effort is expected during an end-inspiratory occlusion in patients who will respond to high PEEP application. Based on this rationale, the investigators developed an index called "Inspiratory Ratio" (IR) to predict the response of patient's inspiratory effort to the application of high PEEP without need of esophageal manometry.

Safety of Nebulized Combination Therapy BromAc® in COVID-19 Respiratory Disease

COVID-19 PneumoniaCOVID-192 more

COVID-19 has multiple facets including cytokine storm, thromboembolism and gelatinous secretions. It is known that oxygen exchange is the main problem in patients with COVID-19 and hypoxia is one of the most serious, in which patients succumb to acute respiratory distress syndrome (ARDS). In other severe respiratory disease such as ventilator associated pneumonia (VAP), formation of biofilm in the endotracheal tube causes infection to spread to the lungs, resulting in respiratory decline and high mortality. The development of gelatinous sputum plugs correlates with negative outcome. Both groups of patients still have limited therapy options. BromAc is a potent mucolytic, biofilm degrader, cleaves the glycoproteins of the SARS-CoV-2 virus (antiviral), and down regulates cytokines and chemokine in COVID-19 sputum. The investigators seek to examine the safety and attempt to gain preliminary efficacy of nebulised BromAc in moderate to severe COVID-19 and other mucus producing, severe, respiratory diseases.

Is Fetal Hemoglobin a Key for Improvement of Hypoxia and Saving Last Breath in COVID-19 Patient?....

COVID-19 Acute Respiratory Distress Syndrome

In December 2019, a sudden public health incident (the corona virus disease [COVID-19] epidemic) occurred in Wuhan, China. Clinical features of those with pneumonia include fever and cough, and in many cases a sudden and accelerating respiratory distress originated from interstitial pneumonia . Many hypotheses have explained hypoxemia in COVID-19 patients, such as hyperimmune reaction to viral infection and cytokine storm that leads to serious lung tissue and alveolar damage or even direct viral insult . Mortality are as high as 15% in critically ill patients requiring intensive care unit admission and oxygen therapy , suggesting an urgent need to try therapeutic interventions in addition to supportive treatment. There is more than one type of hemoglobin. In adults, Hb A or Adult hemoglobin which is the main hemoglobin in the blood. But there is another type of hemoglobin called fetal hemoglobin. Fetal hemoglobin (hemoglobin F, Hb F, or α2γ2) is the main oxygen carrier protein in the human fetus. and the levels remain high after birth until the baby is roughly 2-4 months old . Hemoglobin F has a different composition from hemoglobin A and higher affinity to oxygen . At birth, hemoglobin F accounts for 50-95% of the infant's hemoglobin and at around 6 months after birth, hemoglobin A becomes the predominant type.The key feature that allows hemoglobin F to bind more strongly to oxygen is by having γ subunits (instead of β, in Hb A for example). 2,3-BPG interacts much more with hemoglobin A than hemoglobin F . A hypothesis for the low incidence of the COVID-19 infection in pediatric is the presence of fetal hemoglobin (HbF) . In a preliminary study about the prevalence of hemoglobinopathies in different countries and the mortality rate of COVID-19, it appears that the mortality is lower in countries with a higher prevalence of hemoglobinopathies . Mice treated with GBT1118 (a compound that enhances the oxygen affinity of hemoglobin) showed a sustained significant increase in SpO2 over 4 h of hypoxia exposure. People with haemoglobinopathies like sickle cell anemia or beta-thalassemia attributed with high amount of fetal hemoglobin, become mostly asymptomatic or have mild symptoms . The volume of umbilical cord blood varies from 50 ml to 140 ml with a mean of 85 ml rich in fetal hemoglobin . Mesenchymal stem cells (MSCs) have been widely used in the clinical setting, not only for autoimmune diseases but also for infectious diseases , and their safety and effectiveness have been well elucidated . As a noninvasive treatment, hUC-MSC therapy is a very effective and promising method for clinical application and promotion to treat severe COVID-19 the investigators offer a solution by increasing fetal hemoglobin by cord blood containing fetal blood transfusion in the critical patients as a trial to combat the course of the disease and minimize the morbidity especially in sever cases who suffer from desaturation until suppression of the immune dysregulation and avoidance of the impending death.
