A randomized, double-blind, placebo-controlled study to assess the efficacy and safety of pulsed inhaled iNO compared to placebo in subjects with COVID-19.
QuadraMune(TM) is a nutritional supplement which has previously been demonstrated to possess antiinflammatory and immune modulatory activity based on in vitro and pilot in vivo studies. The current clinical trial aims to assess in a 500 volunteer trial the efficacy of QuadraMune(TM) in reducing infection in individuals at high risk of COVID-19.
For preventing the overwhelming of ICU beds capacity during COVID-19 pandemic in France, national and regional Health-Care institutions decided to optimize the Intensive Care Unit beds availability by opening new ICU beds in institutions with and without prior ICU. The Present study was design to retrospectively describe the origin of the ICU beds and human resources created during the COVID-19 outbreak in France.
Facing the challenge of finding an efficient treatment for COVID-19, the viral pneumonia caused by the Coronavirus SARS-Cov-2, this study intended to test if Chloroquine or Hydroxychloroquine, two drugs with strong in-vitro antiviral role proven by numerous studies and with a well defined safety profile established, for efficacy in treating COVID-19 and improving an ordinal primary outcome composed by a 9-levels scale, which was recomended by the World Health Organization.
The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which originated in Wuhan, China, has become a major concern all over the world. Convalescent plasma or immunoglobulins have been used as a last resort to improve the survival rate of patients with SARS whose condition continued to deteriorate despite treatment with pulsed methylprednisolone. Moreover, several studies showed a shorter hospital stay and lower mortality in patients treated with convalescent plasma than those who were not treated with convalescent plasma. Evidence shows that convalescent plasma from patients who have recovered from viral infections can be used effectively as a treatment of patients with active disease. The use of solutions enriched of antiviral antibodies has several important advantages over the convalescent plasma including the high level of neutralizing antibodies supplied. Moreover, plasma-exchange is expensive and requires large volumes of substitution fluid With either albumin or fresh frozen plasma, increasing the risk of cardiovascular instability in the plasma donor and in the recipient, which can be detrimental in a critically ill patient with COVID 19 pneumonia. The use of plasma as a substitution fluid further increases treatment costs and is associated with risk of infections, allergic reactions and citrate-induced hypocalcemia. Albumin is better tolerated and less expensive, but exchanges using albumin solutions increase the risk of bleeding because of progressive coagulation factor depletion. The aforementioned limitations of plasma therapy can be in part overcome by using selective apheresis methods, such as double-filtration plasmapheresis (DFPP)3. During DFPP, plasma is separated from cellular components by a plasma filter, and is then allowed to pass through a fractionator filter. Depending on the membrane cut-off, the fractionator filter retains larger molecules and returns fluid along with smaller molecules to the circulation. Thus, the selection of a membrane with an appropriate sieving coefficient for IgG allows to efficiently clear autoantibodies in patients with antibody-mediated diseases (e.g., macroglobulinemia, myasthenia gravis and rheumatoid arthritis) with negligible fluid losses and limited removal of albumin and coagulation factors1. In patients with severe membranous nephropathy and high titer of autoreactive, nephritogenic antibodies against the podocyte-expressed M type phospholipase A2 receptor (PLA2R), DFPP accelerated anti PLA2R depletion4. Measurement of the antibody titer in treated patient and recovered fluid showed that antibody removal was extremely effective and that large part of antibodies was removed during the first DFPP procedure. This therapeutic regimen was safe and well tolerated and easy to apply4. In an ongoing pilot study we found that the same methodological approach can be used to remove circulating antibodies from patients who recovered from COVID 19 and to infuse these antibodies in patients with active viral infection. Treatment was well tolerated and preliminary findings are encouraging. Thus, in this novel pilot study we aim to explore whether the infusion of antibodies obtained with one single DFPP procedure from voluntary convalescent donors could offer an effective and safe therapeutic option for patients with earlier stages of coronavirus (COVID-19) pneumonia requiring oxygen supply without mechanical ventilation.
To date no treatment has proven its effectiveness in the caring of patients infected with type 2 Coronavirus. The Centre Hospitalier Princesse Grace (CHPG) has decided to only propose randomized double-blind placebo-controlled clinical trials to patients at the early and symptomatic stages of the disease. Data from the literature show in vitro results on the potential clinical benefit of some treatments such as chloroquine or hydroxychloroquine (HXCQ). Observational data suggest a potential benefit of this treatment alone or in combination with azithromycin (HXCQ + AZ). These data were advertised or led to a request from ambulatory medicine and patients to have access to these treatments despite their poor level of evidence. This leads to a decrease in the number of patients recruitable for clinical trials because they refuse the concept of control arms or they wish active treatment (CQ, HXCQ or HXCQ + AZ) from the start. In this context, we propose to conduct in parallel with randomized trials, a so-called "patient preference" protocol which, after patients information, gives them the choice, either to participate in the trial or to choose between treatment with HXCQ, treatment with HXCQ + AZ or standard of care without medication. The patients follow-up and the main endpoint will be the same under the patient preference protocol as for the randomized trial. The advantage of this approach is to offer a common follow-up to all patients, to take into account patients who refuse to participate in the clinical trial, to obtain external validity data, to reduce selection bias and to increase the heterogeneity of patients exposed to treatment options. The expected objective is to see if the patient preference protocol leads to observe the same effects as in the randomized trial.
In-vitro studies revealed that nafamostat mesylate has antiviral activity against Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and anti-inflammatory and anti-coagulation effect. However, there is no clinical studies on the efficacy of nafamostat in patients with COVID-19. This study is conducted to evaluate the clinical efficacy of nafamostate mesylate in adult patients hospitalized with COVID-19 pneumonia.
The purpose of this study is to assess the safety and efficiency of an assembled modified mask in protecting health care workers against Coronavirus in case of any personal protective equipment shortage. At least 20 healthy participants will be recruited to try the modified mask. The modified masks will be made from masks that are already available as well as filters available in the pulmonary department at the Oklahoma City VA Health Care System
Patients suffering from pneumonia due to SARS-CoV-2 infection, after admission to the Intensive Care Unit (ICU), are susceptible to development of various functional sequelae, increased risk of chronic diseases, increased mortality rates and existence of relevant impacts on their quality of life in the months and years that follow the ICU admission. The present study aims to assess the determinants of health-related quality of life and patient-centered long-term outcomes among patients recovered from SARS-COV-2 pneumonia, after discharge from the ICU, its determinants and predictors, in Portugal. It is a multicenter prospective cohort study of adult patients admitted at the ICU due to proven or suspected SARS-CoV-2 infection, included 90 days after discharge from the ICU. The primary outcome is one-year health-related quality of life assessed by the EQ-5D-3L. The secondary outcomes are all-cause mortality, rehospitalizations, return to work or study, the degree of dependence and functional capacity, symptoms of anxiety, depression and post-traumatic stress, level of physical activity and cognitive, renal and respiratory functions after ICU discharge. Investigators will collect data by means of structured telephone interviews, at a 12 months follow up period.
