Title: The use of Tocilizumab in the management of patients who have severe COVID-19 with suspected pulmonary hyperinflammation. This is a study designed to assess the therapeutic value of intravenous tocilizumab administered as single 8mg/Kg dose in patients affected by SARS-CoV2 infection with a pulmonary manifestation causing hypoxia. Aim of the study is to test the hypothesis that anti-IL6 treatment can be effective in reducing the virus-induced cytokine storm, blocking deterioration of lung function or even promoting a rapid improvement of clinical conditions, preventing tracheal intubation and/or death. This drug will be administered to those patients entering the ICU with severe acute respiratory failure COVID-19 disease. The endpoints are death and duration of hospitalization. The patients will be assessed with surrogate markers determining the level of the cytokine storm.
The understanding of haemostasis and inflammation cross-talk has gained considerable knowledge during the past decade in the field of arterial and venous thrombosis. Complex and delicately balanced interaction between coagulation and inflammation involve all cellular and humoral components. Elements of the coagulation system such as activated thrombin, fibrinogen or factor Xa may increase inflammation by promoting the production of proinflammatory cytokines, chemokines, growth factors and adhesion molecules that lead to a procoagulant state amplifying the pathological process. Recent evidence supports inflammation as a common pathogenic contributor to both arterial and venous thrombosis, giving rise to the concept of inflammation induced thrombosis. Patients with infection of COVID-19 and severe pneumoniae seem to have higher risk of thromboembolism. The purpose of this project is to analyze hemostasis and coagulation of every hospitalized patient with infection of COVID-19. Blood sample for coagulation and hemostasis analysis will be collected on every patient hospitalized in Amiens hospital for COVID-19 infection. Thrombin time, factors V and II, fibrin/fibrinogen degradation products, antithrombin will be assessed every week. Anticardiolipin, anti-beta2 glycoprotein I and anti-annexin A2 antibodies IgG and IgM at day of admission and at fourth week after admission will be assessed. SARS-CoV2 viral load and serodiagnosis will be performed at the same time. At the same time venous ultrasound to diagnose thrombosis will be performed.
Low-dose radiotherapy treatment delivered to both lungs in patients with immune-related pneumonia following COVID-19 infection is backed up by biological and clinical bases that justify its use as a possible therapeutic option in these patients. This is a preliminary exploratory study (non-pharmacological interventional) to evaluate the feasibility and tolerability of low-dose radiotherapy treatment of SARS-Cov-2 immune-mediated pneumonia, for the subsequent implementation of a phase II study.This is a preliminary, monocentric, single-arm, interventional, non-pharmacological exploratory study. All enrolled patients will be treated with low-dose radiotherapy. Participants will undergo irradiation of the lungs, administered in a single fraction at the average prescription dose of 0.7 Gy (further details in the dedicated section).
Use lay language. The Covid-19 pandemic hit France in March 2020 and stage 3 of the epidemic justified the introduction of national and unprecedented containment measures from March 17, 2020. The Montpellier CHU experienced peak hospitalizations of Covid-19 infections in late March. The estimate of the proportion of infected people in Occitania, South of France, for the 11th of May 2020 is 3.1% (95% CI: 1.9-5.9) for the Occitania region, to which Montpellier belongs. In the context of the Covid-19 epidemic, notably due to the absence of pharmacological or vaccine prophylaxis, barrier measures were of crucial importance, especially for exposed caregivers. These measures include an adaptation of individual behavior, the creation of a so-called "Covid" hospital, the wearing of specific equipment in all departments, the use in the rooms of Covid-19 patients of a gown, an apron, gloves, and a FFP2 type mask in the event of contact and sampling, protocolized and standardized bio-cleaning measures, a reorganization of the premises and the definition of specific circuits. In view of the second wave of the epidemic, estimating the effectiveness of the barrier measures is of major importance. The investigators therefore propose an evaluation of the effectiveness of these measures, by comparing the serological prevalence of infection among caregivers working directly in COVID units compared to caregivers working in services excluding the management of Covid-19 patients. Systematic evaluation in COVID-19 units of Sarc-Co-V2 infection will also be assessed, with naso-pharyngeal swabs.
The aim of this project is to introduce way for treatment of patients with severe COVID-19 disease with respiratory complications.
This is a prospective study, involving contacting potential plasma donors and the use of their plasma to help fight off infections of those suffering from COVID19 in accordance to collection guidelines for plasma and FDA IND requirement. This study will include up to 240 participants potentially receiving convalescent plasma and up to 1000 potential donors. There are 3 basic arms to the study: mild, moderate and severe/critical severity. All 3 severity groups are eligible for enrollment, but mild severity will not be given plasma unless there is progression. Moderate severity will given up to 1 unit of plasma and severe/critical severity up to 2 units. There is no placebo group, however given the excepted issues of shortages of plasma, intention to treat will be used for analysis.
The COVID-19 pandemic health crisis forces health institutions to lower their standards of protection as supplies of personal protective equipment decrease despite the safety of front-line workers worldwide . This shortage specifically affects high-quality protective masks, such as those called FFP2. As alternatives, we offer a reusable mask based on a ventilation mask combined with a breathing filter for anesthesia breathing circuits. The purpose of the study is to assess the sealing potential of this mask in the field and possibly prove a non-inferior sealing compared to standard masks type FFP2.
This study aims to observe the long-term health-related quality of life (HRQOL) and physical performance in individuals hospitalized due to a COVID-19 infection. Therefore, data is extracted from a study-site standard aftercare program which has been adjusted for this patient population. This comprehensive aftercare program includes education sessions and physical exercise. A second aim is to observe adherence and feasibility to the program and if indicated compare the clinical data and outcomes from patients following the program with patients denying to participate in guided exercise and education sessions. It is expected that patients hospitalized due to COVID-19 infection show a reduction in physical performance and HRQOL directly after discharge. The severity of illness is hypothesized to be associated with a reduction as well in HRQOL and physical performance after one-year post-discharge.
SARS-CoV-2 belong to beta-coronavirus family and its transmission route and symptoms follow those of all community-acquired coronaviruses. The main difference of the novel Coronavirus is the higher mortality rate, that is around 3%. Death rate is over 1% only for patients over 50 years old, whereas until 40 years old is under 0,4%. No fatalities are declared among children under 10 years old to date. Death rate is almost double for male rather than female. This distribution of mortality rate according to age of infected patients could be only partially ascribed to other comorbidities in addition to great age. In fact, patients with no pre-existing conditions have however a case fatality rate of 0,9%. The almost null rate of severe illness in children and generally in patients younger than 40 years old is quite un-explicable. Infant, children and young people could be infected but infection is rapidly self-limited or without symptoms. Older patients undergo severe lung injury as consequence of an immune response that is late in coming. Possible explanation of these phenomena could be something, which assure ability to prompt response to SARS-CoV-2 in younger people independently from the novelty of the virus itself. It would seem to be that younger people are already sensitized to the antigens of the virus without a previous contact. This immunity is not really specific, but "partially specific" for many antigens of the virus, however able to limit the infection in the organism. Something stimulated the immune system and it scattered immunity against more and more antigens present. Children are the age group mostly exposed to all community-circulating viruses. This immunity is not persistent but progressively fade out. It protects from the age of two, when the hypothetical stimulation occurs, to the fifth decade because of its slow decrease. The only external stimulation, which healthy people receive are vaccines. All vaccinations and especially tetanic, diphtheria toxoids and inactivated bacteria as pertussis could stimulate immune system. They develop the specific immunity but generate also a sprouting immunity against antigens in transit, as coronaviruses and other community-circulating viruses. The developed immunity gives some protection against multiple viral infection for years until the natural fade out. After the fifth decade, that immunity is slower to be recall and reactivated. Additionally, transplant recipients and HIV infected patients, which have an immune system inhibited, unexpectedly, do not seem to suffer the worst complications of SARS-CoV-2 infection. An immune system imbalance could be play a pivotal role during the reaction to the virus, limiting destructive consequences of excessive inflammation. According to the medical hypothesis on which the protocol is based on, young people could benefit from a functional adaptation of innate immune cells induced through epigenetic reprogramming and, especially, a pre-existing "partially specific" immunity to the community viruses caused by "bystander effect" of preceding vaccinations. In this study, we will explore the main differences existing among patients infected by SARS-CoV-2 who experience the illness at different degree of severity. We suppose to recognize different populations of patients, each one with a specific immunological pattern. It could differ in terms of cytokines, soluble factors serum level and immune cells activity both of the innate compartment and of the acquired one. The proof of a role of these immunological phenomena in the pathogenesis of Covid-19 are bases for implementation of therapeutic immunomodulatory treatments. In addition, the definition of an immunological risk profile could tailor established therapies to each kind of patient.
