Filter by:The ARCADIA Trial is a randomised, double-blind, placebo-controlled clinical trial to assess the safety and efficacy of AZD1656 in patients with either Type 1 or Type 2 diabetes, hospitalised with COVID-19.
The aim of the study is to assess the safety, efficacy, and immunogenicity of AZD1222 for the prevention of COVID-19.
This is a first-in-human (FIH), Phase 1, single-center, randomized, double-blind, placebo-controlled, single ascending dose study to evaluate the safety, tolerability, PK and immunogenicity of AK119, a humanized monoclonal antibody targeting the CD73. The study will consist of 4 cohorts of healthy subjects. Eight subjects will be enrolled per cohort, randomized in a 3:1 ratio to receive a single dose of either the active drug AK119 (N=6) or matching placebo (N=2). Approximately 32 subjects (24 receiving active drug and 8 receiving placebo) will participate in this study.
"Background France counted on January 1, 2020, 70,651 people detained, for 61,080 places. Overcrowding in detention is considered as risk factor for infectious diseases transmission, such as respiratory infections. The prison environment represents a confined environment, which could protect prisoners from possible external contamination. If one or more inmates were infected through visiting rooms, officers working in detention, or newly incarcerated people, an epidemic could spread more quickly in the prison community. Thus, few cases of COVID-19 were observed among the subjects in detention with a few weeks delay compared to the free world. However, detention conditions make it more difficult to detect suspicious cases. On the other hand, carrying out diagnostic tests is structurally more difficult to carry out there. Thus, given the plurality of clinical presentations, the non-optimal sensitivity of the SARS-CoV-2 RT-PCR, and the difficulty in carrying out diagnostic tests, it is today difficult to have a precise idea of the number of prisoners having encountered SARS-CoV-2. It is also a population that is not taken into account in the large seroprevalence studies currently conducted in the general population. In order to estimate the number of prisoners exposed to SARS-CoV-2 and in the absence of data currently available in the medical literature, a seroprevalence study in this at risk and little studied population would bring new data to the medical community. Hypothesis In adult subjects living in penal establishments in Ile de France, the seroprevalence of SARS-CoV-2 would be lower compared to the general population. Material and method Open multicenter cross-sectional study carried out in the 11 penal establishments of Ile de France. A sampling of 3,500 inmates stratified over the 16 detention areas concerned will be carried out. The inclusion criteria will be detained subjects who have expressed their consent to participate in the research, aged 18 to 80 years. Each selected detainee will be invited to the health unit to perform a venous blood test for anti-SARS-CoV-2 antibodies. The goal is to take 2,500 blood samples (30% expected refusal rate). Each sample will be analyzed in the virology laboratory at P. Brousse hospital. Expected results Obtain an assessment of the seroprevalence of SARS-CoV-2 in prisons to determine the exposure of detained persons. This assessment will make it possible to undertake public health actions and to propose the implementation of group protection measures such as vaccination if this is soon available.
Pandemic SARS-CoV-2 (COVID-19) respiratory infection is responsible for more than 4,000 deaths, mainly (67%) secondary to acute respiratory distress syndromes (ARDS). ARDS is usually associated with a mortality of around 40%, but this rate reaches 61% in patients infected with SARS-CoV-2. Two endotypes have been described in patients with ARDS: one, hyper-inflammatory, associated with very high mortality (51%); the second, slightly inflammatory (immunoparalysis), associated with much lower mortality (19%). In COVID-19 patients, distinct immune response profiles have also been observed. Some patients present deep lymphopenia and/or prolonged viral excretions associated with more frequent occurrence of co-infections (+ 29% of virus, + 23% of bacteria, + 10% of fungi). The latter group may be at higher risk in terms of mortality. The intensity of the inflammatory response and/or microbial coinfections therefore appear as risk factors for severity and mortality in patients infected with SARS-CoV-2 which determine the course of the disease. To adapt early optimal therapeutic management to each forms of the disease, it is essential to be able to characterize these profiles on the microbiological and inflammatory level. With a committed network of 6 intensive-care units across eastern and northern Ile-de-France, 180 patients with ARDS and infected with SARS-CoV-2 are being enrolled. For these patients, a nasopharyngeal swab is collected at inclusion; followed by a new nasopharyngeal swab and a deep respiratory sample once a week, until D28, for an exploration of co-infections and for monitoring the viral load of SARS-CoV-2. The rest of each of these samples are collected for the study. In parallel, the clinical data usually collected in the context of intensive care will be collected on a CRF. They will allow to calculate risk scores such as SOFA.
Keeping in mind the rising number of cases in Egypt and the strain they put on hospital infrastructure, the idea of home isolation and follow up for COVID 19 positive cases has been adopted in many countries and was approved by World Health Organization (WHO) and Egyptian Ministry of health (MOH). Telehealth can help to mitigate this risk by minimizing the amount of face-to-face interactions. The WHO mentioned telemedicine among essential services in "strengthening the Health Systems Response to COVID-19" policy. The aim in this study is to study the effectiveness of telemedicine in managing mild COVID cases regarding isolation measures, symptoms, medications adherence, and reporting of red flags and side effects.
This study aims to evaluate the safety and reactogenicity profile after 1 and 2 dose administrations of investigational SARS-CoV-2 mRNA vaccine (CVnCoV) at different dose levels and to evaluate the humoral immune response after 1 and 2 dose administrations of CVnCoV.
Complete blood count parameters are routinely evaluated cost-effective markers in diagnosis and clinical follow-up of infectious diseases.There is increasing number of studies to report the course of COVID-19 in pregnancy. The current study aimed to elucidate the changes in hematologic parameters in response to SARS-CoV-2 infection and whether there was an increase in adverse perinatal outcomes such as increased neonatal intensive care unit admission and lower APGAR scores in pregnancies with COVID-19.
The aeronautical community was also affected and greatly impacted economically and socially by the Covid-19 pandemic. Away from the acute phase, the epidemiological impact and the consequences of this disease within the French aviation flight crew population must be assessed. This study is aimed at providing original epidemiological data among civil and military aircrew, prior to possible prevention strategies or countermeasures to optimize risk management in terms of aviation safety and to promote, if necessary, future targeted studies.
COVID-19 is a disease caused by the virus, SARS-CoV-2. Patients with this viral infection are at risk for developing pneumonia and acute respiratory distress syndrome (ARDS). Approximately 20% to 30% of hospitalized patients with COVID-19 and pneumonia require intensive care for respiratory support. Clinically, ARDS presents with severe hypoxemia evolving over several days to a week in combination with bilateral pulmonary infiltrates on chest X-ray. Widespread alveolar epithelial cell and pulmonary capillary endothelial injury can lead to severe impairment in gas exchange. In one report of 1,099 patients hospitalized with COVID-19, ARDS occurred in 15.6% of patients with severe pneumonia. In a smaller case series of 138 hospitalized patients, ARDS occurred in 19.6% of patients and in 61.1% of patients admitted to an intensive care unit (ICU). To date, no effective treatment has been established to treat COVID-19 or to prevent progression of ARDS. It is thought that a heightened immune response with an unbalanced release of inflammatory mediators in the airway is a major cause of morbidity and mortality associated with the disease. It is therefore reasonable to postulate that improved outcomes may be obtained in patients with a balanced immune response with adequate viral control and appropriate counter-regulatory immune responses whereas a poor outcome may be expected in patients with inadequate viral control or a heightened immune response or what is referred to as a "cytokine storm". Thus, modulating the pulmonary immune response without suppressing the immune system would be a viable strategy for patients with COVID-19. The current literature supports the role of neuromodulation, particularly vagal nerve stimulation (VNS), in modulating the immune response. Modulating the pro-inflammatory pathway through VNS has been demonstrated to decrease inflammatory mediators and improve outcomes in several animal models and in humans. Percutaneous electrical nerve field stimulation (PENFS) provides a novel, non-invasive method of VNS through a non-implantable device applied to the external ear. Already, the FDA has cleared this technology for reducing symptoms of opioid withdrawal in patients with opioid use disorder. Symptoms of opioid withdrawal can be decreased by approximately 90% after 1 hour of stimulation. Similarly, the IB-Stim device has been shown to improve symptom in children with abdominal-pain-related functional GI disorders and recently received market approval by the FDA for that indication. Unpublished studies have demonstrated marked decrease in inflammation with PENFS compared to sham stimulation in a model of TNBS colitis. While the efficacy of PENFS in modulating the progression of pulmonary disease in patients with COVID-19 is unknown, several proposed mechanisms for regulation of the immune response through VNS have already been demonstrated. We propose to perform an open label, randomized study to evaluate the efficacy of PENFS for the treatment of respiratory symptoms in patients with COVID-19.
