Active clinical trials for "COVID-19"

This is a prospective study analyzing the development of humoral immune response against SARS-Cov-2 in patients with previous Covid19: the aim is to compare the incidence, titration and evolution of IgG an IgM in a prospective cohort of liver transplant patients surviving to the first wave of Covid19, in comparison to not inmmunossupressed patients.

End-stage organ failure is estimated to affect more than 4 to 6 million persons worldwide. In 2018, transplant systems across the globe enabled around 150,000 patients to benefit from a kidney, heart, lung, liver, or other solid organ, a number that was far less than the demand. According to data from the World Health Organization, more than 1,500,000 persons live with a transplanted organ worldwide. In the US, approximately 40,000 patients receive an organ transplant every year, but 120,000 still remain waitlisted for transplantation today, with 7,600 dying annually while waiting for an organ transplant. A similar lack of organs and high death rates on the waiting list affect patients in Europe and many other countries. As nations adjust to new realities driven by the coronavirus (COVID-19) outbreak, many health care providers, institutions and patients are concerned about the potential impact that COVID-19 will have on organ donation and transplantation. One concern is that transplant recipients may have a greater susceptibility to infection and greater viral burden. A second concern is that hospitals will lack the resources in terms of staff and equipment to care for recipients after transplantation, who often require intensive care and multispecialty management. Because of the overwhelming healthcare system burden, a dramatic negative effect on worldwide organ donation and transplantation is anticipated, but has not been measured. Our objective was to quantify the worldwide impact of COVID-19 pandemic on organ donation and transplantation and consequences for waitlisted patients.

This cross-sectional observational study will collect information about changes in exacerbation frequency and behaviour amongst a clinical cohort of severe or complex COPD clinic patients. This will be done through a combination of telephone survey and access to electronic heath records.

There is an evidence gap in relation to the incidence, impact and severity of COVID-19 in newborn babies. International data are very limited, we have no robust estimates of incidence and no UK-based data with which to inform policy, clinical care, service delivery or advice to pregnant women. The research aims are to investigate the three mains ways in which COVID-19 might affect newborns and babies that need neonatal care: Newborn babies might catch COVID-19 before, during or soon after birth and this may lead to problems with breathing or feeding that need support in hospital. COVID-19 could affect babies that are already on neonatal units with other medical conditions (like being very premature) that place them at greater risk of severe COVID-19. COVID-19 might affect that way that pregnant women are looked after in pregnancy, labour or bith which could lead to problems for some babies, even if they do not themselves become infected with COVID-19.

This is an observational patient registry of COVID-19 patients treated with HBOT.

The aim of the present study is to examine whether cerebral oxygenation could be a more useful parameter than peripheral oxygen saturation to guide clinical titration of permissive hypoxemia in COVID-19 ARDS patients

Background: There is a current worldwide outbreak of the novel coronavirus Covid-19 which originated from Wuhan in China and has now spread to 6 continents including 210 countries. There is still a lack of any report about severe acute respiratory syndromes (SARS-CoV-2) genetic polymorphisms which are associated with the susceptibility to infection. In addition, gene polymorphisms of MBL (mannose-binding lectin) associated with antigen presentation are related to the risk of SARS-CoV infection. Aim: To investigate the association of different genetic markers of different mechanisms of viral pathogenesis with the outcome of COVID-19. Methods: The study will include one hundred patients diagnosed as COVID-19. Biological blood samples will be taken for routine diagnostic analysis, routine molecular testing using Real-time polymerase chain reaction (PCR), Allelic discrimination and genotyping analysis. Outcome: Different genetic markers could play a role in the outcome and prognosis of COVID-19 viral infection.

This study will evaluate the changes in sexual function, reproductive function and mental health of male patients discharged from the hospital with COVID-19, and the impact of SARS-CoV-2 on male reproductive health and mental health compared with healthy people during the same period. In addition, men's semen examination reports before and after the new coronavirus pneumonia event will be collected and compared to assess the impact of the event on the quality of men's semen. Also, This study will test the SARS-CoV-2 nucleic acid of the urogenital system of male patients discharged with COVID-19 to provide evidence for the effect of the new coronavirus on the male reproductive system.

Quarantine related to the Covid-19 pandemic has begun on the 03/17/2020 in France. Quarantine has already be linked to pejorative effects on mental health. In this study, we aim to evaluated PTSD symptoms of patients already followed by a psychiatrist during quarantine, one month and 3 months after inclusion. It will be also evaluate various psychiatric symptoms.

The main objective of our project is to investigate the evolution of psychosocial, cardiovascular and immune markers in healthcare with different levels of exposure to the COVID-19 pandemic.
