Active clinical trials for "COVID-19"

Many questions about management of COVID-19 are still not answered. So, we recruit this study aiming to evaluate improvement of oxygenation in COVID-19 patients with severe ARDS, to improve morbidity and mortality of ICU covid patients, to participate in understanding of real hidden pathophysiology of COVID-19.

In 2017, 10.7 million people affiliated to the general health insurance scheme benefited from the "Long-term condition" scheme, i.e. 17% of insured patients. Most of these patients suffer from chronic diseases requiring regular medical and paramedical follow-up. During the first containment period of the SARS-CoV-2 epidemic, the French government's messages were to call the Urgent Medical Assistance Service (15) and not to go directly to the general practitioner (GP), favouring teleconsultations. Other countries have adopted the same strategy. Mortality rates due to SARS-CoV-2 infection were higher in elderly patients and/or those with co-morbidities, particularly heart failure, hypertension, respiratory failure and diabetes. The elderly and patients with chronic cardiometabolic and respiratory diseases should therefore be particularly protected during the epidemic. However, these populations also need close monitoring to avoid acute decompensation of their chronic diseases or loss of autonomy. However, during the first containment, general practitioners and other medical and paramedical ambulatory health professionals perceived a notable decrease in their daily activity, including for their chronic and/or elderly patients who may not have called for a visit, consultation and/or access to telemedicine. "Public Health France" also reported a decrease in consultations with GPs at the beginning of the lockdown, a decrease in the number of emergency room visits and hospitalizations for cardio and neurovascular diseases. The investigators hypothesise that under-attendance of primary care services during the epidemic is associated with excess mortality and morbidity unrelated to COVID-19. The main objective is to assess non-COVID-19 related overmortality during the containment period and 12 months after the start of containment, in a population of elderly and/or chronically ill patients in France. The overmortality will be assessed globally and according to individual and contextual characteristics such as gender, age, place of residence, pre-existing morbidity and socio-economic level.

Patients with treatment history of rituximab since 01.01.2019 and immunocompetent volunteers will be contacted to give a blood sample after their COVID19 vaccination, and in a subset also before vaccination. Immune responses of antibodies and SARS-CoV2-specific T-cells to the vaccination will be quantified and the rituximab effect on COVID19 vaccine-induced immune responses is analyzed.

Vaccination remains the main promising measure to fight against the COVID-19 pandemic. The presumed efficacy of the vaccines is quite remarkable since it varies between 62 and 95%. There is increasing evidence that sex-specific effects may lead to different outcomes of vaccine safety and efficacy. However, sex-disaggregated data after COVID-19 vaccine are lacking. The first purpose of the study is to determine antibody titers against SARS-CoV-2 spike after COVID-19 vaccination. The secondary purpose is to identify predictor factors of immune response including age, gender and biological factors.

This study is aiming to evaluate the effects of the COVID-19 pandemic stress on pregnancy outcomes including the sex ratio at birth.

The determinants of the evolution to a severe form for COVID-19 pneumonia remain unclear. COVID-19 pneumonia is characterized by a hypoxemia with a possible rapid worsening and related resuscitation requirement. The monitoring of patients in hospital wards (excluding intensive care unit) is therefore both necessary and complicated given the contagious risks for health workers. The COVID 19 Respiratory Tele Monitoring (RTM COVID 19) research project is based on a comparison between usual nurse respiratory monitoring (4 to 6 time per day) of respiratory parameters (capillary oxygen saturation, respiratory rate, hearth rate) and a continuous monitoring of these respiratory parameters with continuous monitoring by a portable, wireless and stand-alone device. The main objective of this work is a more sensitive and earlier detection of respiratory degradation events in patients with COVID-19 pneumonia (capillary desaturation, increased respiratory rate) requiring the introduction of oxygen therapy, its increase or a resuscitation requirement with possible intensive care admission. A prospective, randomized, multicentre, comparative exposure study will be conducted with planned inclusion of 80 patients. This investigation will focus on patients with COVID-19 pneumonia hospitalized in dedicated medical wards of two University Hospitals in France. A randomization will be stratified by Hospital and adapted so that each Hospital provides the same number of subjects in each arms: Control Respiratory Monitoring Group (40 patients) Experimental Respiratory Monitoring Group (40 patients) The main criterion is respiratory degradation event, during a 4 days period after ward admission, which motivates a change in the therapeutic strategy defined by the presence of at least one of these elements: Capillary saturation < 94% (regardless of oxygen intake) for at least 2 minutes. And/or an increase in respiratory rate > 20/minute for at least 2 minutes. The modification of the therapeutic strategy is defined by: Introduction of oxygen therapy for included patients without oxygen therapy or supplementation of oxygen therapy > 2 litres/minutes for included patients with oxygen therapy And/or introduction of a high oxygen concentration mask And/or Request an On-Site Opinion from a member of the resuscitation team. And/or Transfer to intensive care or resuscitation unit And/or Need for immediate resuscitation for life-threatening distress.

Coronavirus Disease 2019 (COVID-19) emerged in December 2019, and in mere few months has resulted in a pandemic of viral pneumonia. Substantial proportion of patients with COVID-19 have biochemical evidence of myocardial injuries during the acute phase. Possible mechanisms including acute coronary events, cytokine storm, and COVID-19 related myocarditis, have been postulated for the cardiac involvement in COVID-19. It is uncertain whether COVID-19 survivors are at risk cardiac dysfunction including cardiac arrhythmia and heart failure. The prospective screening study aims to evaluate the possible latent effects from COVID-19 in COVID-19 survivors. COVID-19 survivors 4-6 weeks after hospital discharge will be recruited from the Infectious Disease clinic, Queen Mary Hospital with standard 12-lead electrocardiogram, serum troponin, NT-proBNP, and standard transthoracic echocardiogram. The outcome measures include (1) new onset cardiac arrhythmia, (2) N Terminal (NT)-proBNP elevation above the diagnostic range of heart failure, and (3) newly detected left ventricular dysfunction.

It is an observational, cohort, retrospective, monocentric, non-profit study. The primary objective is to evaluate the efficacy and safety of ruxolitinib in acute respiratory distress syndrome in patients with SARS-CoV-2 COVID-19 with rapid deterioration of respiratory parameters in the last 12 hours.

The aim of the study is to understand the impact of COVID-19 on People with Multiple Sclerosis in the United Kingdom.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) poses a significant threat to global health. As the disease progresses, a series of acute complications tend to develop in multiple organs. Beyond the supportive care, no specific treatment has been established for COVID-19. The effectiveness, both short-term and long-term, of some promising antivirals, such as the hydroxychloroquine combination with azithromycin, needs to be evaluated. This study aims to investigate the predictive role of cardiac biomarkers and pulmonary symptoms for late complications of COVID-19 coronavirus infection on the heart and lung in patients treated with the hydroxychloroquine / azithromycin combination therapy. Thus, COVID-19 coronavirus patients undergoing hydroxychloroquine / azithromycin combination therapy will be compared to patients not undergoing this therapy. The comparison will be made by the analysis of the relationships between (1) levels of ultrasensitive cardiac troponins collected at the beginning of the infection and cardiac magnetic resonance data in the 3rd and 12th months of troponin collection and (2) findings CT scans and the results of the ergospirometers tests performed in those same periods. It is expected to demonstrate that: (1) cardiac troponin and lung tomographic findings can predict late complications of COVID-19 coronavirus infection in the heart and lung, assessed by cardiac magnetic resonance and ergospirometers one year after the beginning of the infection, and (2) hydroxychloroquine / azithromycin combined therapy can abolish the onset of these complications late. Furthermore, the results may point to the need for more rigorous monitoring of cardiologists and pulmonologists of these patients, due to the risk of hemodynamic complications, arrhythmogenic and respiratory.
