COVID-19 Clinical Trials and Expanded Access

The main manifestation of COVID-19 is acute hypoxemic respiratory failure (AHRF). In patients with AHRF, the need for invasive mechanical ventilation is associated with high mortality. Two hypotheses will be tested in this study. The first hypothesis is the benefit of corticosteroid therapy on severe COVID-19 infection admitted in ICU in terms of survival. The second hypothesis is that, in the subset of patients free of mechanical ventilation at admission, either Continuous Positive Airway Pressure (CPAP) or High-Flow Nasal Oxygen (HFNO) allows to reduce intubation rate safely during COVID-19 related acute hypoxemic respiratory failure.

The purpose of the study is to evaluate an effectiveness of the drug Dalargin for the prevention and treatment of severe pulmonary complications symptoms associated with severe and critical coronavirus infection cases (SARS COVID19, expanded as Severe acute respiratory syndrome Cоrona Virus Disease 2019 ). Test drug that will be administered to patients are: - Dalargin, solution for inhalation administration, - Dalargin, solution for intravenous and intramuscular administration.

The Nancy Cov-H-AKI: study is a prospective, non-randomized, monocenter study performed in patients hospitalised for either the severe or the critical form of Covid-19. The main objective of the Nancy Cov-H-AKI study is to evaluate the association of variations (from inclusion to 72H post-inclusion) of 5 blood-based cardio-vascular-renal biomarkers selected a priori, cardiac (NT-proBNP), coagulation (D-dimers), related to the renin angiotensin aldosterone system (ACE2) and renal (Penkid, and NGAL) with the appearance of acute kidney injury KDIGO grade 1 or higher OR cardiac injury in patients hospitalised for either the severe or the critical form of Covid-19

The COVID-19 global pandemic has led to a major professional and social national reorganization: professional because it involves a redeployment of medical staff and material resources, and social because it imposes prolonged containment measures on an entire population. The maxillofacial trauma activity is mainly linked to sports or leisure accidents, fights and road accidents. It seems to appear since the beginning of containment measures a significant drop in maxillofacial trauma activity at the national level, which, if it is demonstrated in a significant way in several French hospital centers, would allow to redeploy the material and human resources related to this activity on sectors in tension due to the pandemic.

This study will be concerned with managing patients of Covid-19 while being home isolated.

The prone position during mechanical ventilation in patients with Acute Respiratory Distress Syndrome (ARDS) is able to improve oxygenation and thus reduce mortality. The objective of the study is to evaluate the ability of the prone position to increase the oxygenation of the patient with SARS-cov-2 pneumonia.

The outbreak of coronavirus disease 2019 (COVID-19) at the end of 2019 has seen numerous patients experiencing severe acute lung injury (ALI), which developed into severe respiratory distress syndrome (ARDS). The mortality was as high as 20% -40%. Due to the lack of effective antiviral treatments, supporting treatment is the predominant therapy for COVID-19 pneumonia. Its cure is essentially dependent on the patient's immunity. While the immune system eliminates the virus, numerous inflammatory cytokines are produced and a cytokine storm occurs in severe cases. Mesenchymal stem cells (MSCs) play an important role in injury repair and immune regulation, showing advantageous prospects in the treatment of COVID-19 pneumonia. MSCs prevent cytokine storms by retarding the TNF-α pathway, alleviate sepsis by modulating macrophages, neutrophils, NK cells, DC cells, T lymphocytes and B lymphocytes. After infused, MSCs aggregate in the lungs, improve the lung microenvironment, protect alveolar epithelia, and improve pulmonary fibrosis and pulmonary function.

This protocol will evaluate the efficacy of Therapeutic Plasma Exchange alone or in combination with ruxolitinib in COVID positive patients with PENN grade 2, 3, 4 cytokine release syndrome. It is hypothesized that dual intervention of acute apheretic depletion of cytokines and concomitant suppression of production will produce superior amelioration of the cytokine load and to help to prevent cytokine load rebound. This protocol is envisioned as a pilot study (n=20) for hypothesis generation for future investigation.

The human disease caused by SARS-CoV-2 is called COVID-19. In most cases, COVID-19 presents as a mild to moderate respiratory illness. But it can also be more severe and even lead to death. The purpose of this study is to: - Determine the prevalence of SARS-CoV-2 carrier status over time in children and parents - Determine the prevalence of antibody development over time in children and parents - Compare carrier status and antibody development for children with asthma and/or other atopic conditions (e.g. eczema) versus children without asthma and/or other atopic conditions - Investigate the presence of SARS-CoV-2 exposure in historical samples from enrolled participants

NLR has previously been observed to correlate with complications in upper GI (1) and colorectal (2) surgery. The investigators sought to assess if a similar correlation can be identified in emergency general surgical patients and if the presence of suspected or confirmed COVID-19 may impact on this. The investigators therefore plan to perform a retrospective review of patients having emergency general surgery at a single NHS site during COVID-19 pandemic. Assessment of outcomes and Neutrophil:lymphocyte ratio as a predictor of outcomes will be completed. Outcomes will be completed in line with the recent COVIDSurg study criteria (3). The primary outcome is 30-day mortality. Secondary outcomes are 7-day mortality, re-operation, length of stay, post-operative respiratory failure, post-operative ARDS (Acute Respiratory Distress Syndrome), post-operative sepsis and ITU (Intensive Therapy Unit)/HDU (High Dependency Unit) admission.
