Filter by:The pathophysiology of ARDS is linked to an uncontrolled inflammatory response at the level of alveolo-capillary membrane, mediated by neutrophils and mononuclear cells. The complement system and anaphylatoxin C5a have shown central role in the recruitment of these pro-inflammatory cells and more broadly in the genesis of cytokinic storm syndrome. C5a acts via receptors C5aR and C5L2. This is a preliminary study aimed at studying the expression of the C5a receptor on myeloid cells in peripheral blood of patients with ARDS secondary to COVID-19. This study has of primary objective to show there is an overexpression of the C5a receptor in patients with ARDS secondary to COVID-19 compared to control patients (patients with COVID-19 without respiratory distress and healthy volunteers). The medium-term objective is to develop a clinical trial to test the effectiveness of anti-C5aR antibody in this condition.
A prospective, longitudinal, observational cohort study looking at patients following COVID-19 disease using multi-parametric magnetic resonance imaging (MRI) to assess the degree and prevalence of organ injury.
To date, there is no vaccine or treatment with proven efficiency against COVID-19, and the transmissibility of the SARS-CoV-2 virus can be inferred by its identification in the oro-nasopharynx. The bacillus Calmette Guérin (BCG) has the potential for cross-protection against viral infections. This study evaluates the impact of previous (priming effect, from the titer of anti-BCG interferon-gamma) or current BCG exposure (boost with intradermal vaccine) on 1) clinical evolution of COVID-19; 2) elimination of SARS-CoV-2 at different times and disease phenotypes; and 3) seroconversion rate and titration (anti-SARS-CoV-2 IgA, IgM, and IgG).
Treatments for COVID-19 are urgently needed. Hydroxychloroquine (HCQ) is an antimalarial and immunomodulatory agent being repurposed for COVID-19 therapy based off in vitro data suggesting a possible antiviral effect. However, HCQ's effect on COVID-19 in human infection remains unknown. To fill this knowledge gap, we will enroll 626 adult patients hospitalized with laboratory-confirmed COVID-19 and randomize them 1:1 to a five-day course of HCQ or placebo. Notable exclusion criteria include ICU admission or ventilation on enrollment, prior therapy with HCQ, and baseline prolonged qTC. Our primary endpoint is a severe disease progression composite outcome (death, ICU admission, mechanical ventilation, ECMO, , and/or vasopressor requirement) at the 14-day post-treatment evaluation. Notable secondary clinical outcomes include 30-day mortality, hospital length of stay, noninvasive ventilator support, and cytokine release syndrome (CRS) grading scale. Secondary exploratory objectives will examine SARS-CoV-2 viral eradication at the EOT, changes in COVID-19 putative prognostic markers and cytokine levels, and titers of anti-SARS-CoV-2 antibodies. This randomized trial will determine if HCQ is effective as treatment in hospitalized non-ICU patients with COVID-19.
A dynamic analytical tool is being implemented to monitor the health, psychosocial and economic impacts of the COVID-19 pandemic as the crisis unfolds. A longitudinal survey is distributed via a network of hospitals, provincial/national organizations and web platforms. The survey information can be linked to provincial health administrative data and metrics derived from social media activity based on artificial intelligence methods. Targeted questions are included for critical populations such as healthcare workers and people with chronic illnesses.
The purpose of this pilot study is to measure the impact of non-invasive pneumatic manipulation of transthoracic pressure on oxygenation in patients with Acute Respiratory Distress Syndrome (ARDS) due to Coronavirus Disease 2019 (COVID 19) who are on mechanical ventilator support. This will be achieved by a pneumatic Vest placed around the chest wall of consenting patients who meet inclusion criteria. The Vest is essentially a non-invasive segmental device placed upon the anterior and posterior right and left aspects of the chest wall. The researchers have the ability to inflate and deflate the chambers of the Vest to achieve preset pressures as determined by the protocol and observe the patient's physiological response. Participants will have up to four hours of intervention with the study intervention, followed by 1 hour of post-intervention observation.
This study evaluated the efficacy, safety, pharmacokinetics, and pharmacodynamics of ravulizumab administered in adult participants with coronavirus disease 2019 (COVID-19) severe pneumonia, acute lung injury, or acute respiratory distress syndrome. Participants were randomly assigned to receive ravulizumab in addition to best supportive care (BSC) (2/3 of the participants) or BSC alone (1/3 of the participants). BSC consisted of medical treatment and/or medical interventions per routine hospital practice.

This research proposes to study a large healthy population active for the presence of antibodies directed against the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus and this over time. After verification of the inclusion criteria and information by the coordinating investigative doctor, the volunteers sign a written consent. A nurse will take blood samples under safe conditions compatible with the pandemic period and while respecting the protection of the volunteer's personal data. The blood samples will be taken at 4 times for Institute Curie and Institute Pasteur: T0 (day of inclusion), between 6 weeks and 3 months ,6 months and 12 months post-inclusion. Each blood sample consists of a collection of 5 mL of blood in a dry tube. The serum samples will be extracted and collected prospectively from the blood samples. The nasopharyngeal swabs will be performed at 3 times: , between 6 weeks and 3 months, 6 months and 12 months post-inclusion for Institute Curie staff who have had at least one of the following four criteria on the sample or questionnaire carried out at T0: - have had RT-PCR+ - and/or presence of antibodies at the 95% threshold - and/or anosmia/ageusia - and/or digestive syndrome with associated respiratory signs. In case of infection between sampling times, if the volunteer meets one of the four criteria above, a nasopharyngeal swab will be performed during the following visits. The nasopharyngeal swab shall also be proposed to volunteers not meeting the 4 above listed criteria in order to have a control group (about 100 volunteers) for future statistical analyses. If the volunteers accept, naso-pharyngeal swab shall be performed between 6 weeks and 3 months, 6 months and 12 months after inclusion. For volunteers already included at Institute Curie : in case of proved (RT-PCR+ or antigenic +) or very likely (anosmia and/or ageusia, and/or digestive syndrome with associated respiratory signs) between 2 sampling times already planned in the flow chart, blood samples and nasopharyngeal swabs shall be performed. Those shall be performed if time since last planned sampling(s) has been more than 3 weeks or if time until next sampling(s) is more than 3 weeks. The blood samplings and nasopharyngeal swabs will be performed at 4 times for Institute Pasteur personnel: at T0 (inclusion day), between 6 weeks and 3 months, at 6 months and 12 months post-inclusion
