Active clinical trials for "Coronavirus Infections"

This study is to gain critical knowledge to understand the factors influencing the outcome of a pandemic virus within the city of Basel.

This study is a prospective, single center, observational, cohort study of patients to (1) describe the kinetics and temporal relationship of changes in eicosanoid and cytokine mediators in patients with severe COVID-19 admitted to the hospital; and (2) correlate the dynamic changes in eicosanoid mediators with available patient clinical status, including measures of severity of illness, routine laboratory tests, and outcomes.

At the end of January 2020, the international community was informed of the presence of a new viral disease that started in Wuhan (China) and spread rapidly throughout the world. The identified virus belonged to the coronavirus family (SARS-CoV-2) and the disease was named COVID-19. Today there are more than 2 million people diagnosed in Spain and more than 40 thousand in Extremadura. The partial knowledge about the development, evolution of the affected citizenship and their prognosis both early and late makes it necessary to analyze in depth their global and particular characteristics. We will carry out a multicenter, observational, descriptive, cross-sectional and longitudinal study of patients diagnosed with SARS-CoV-2 virus infection in the Community of Extremadura to determine the effectiveness of drug treatments and the clinical and evolutionary characteristics of these patients and the different factors that may influence its evolution.

This national study will recruit expectant mothers with and without positive nasopharyngeal swabs for SARS-CoV-2, and aims to determine the seroepidemiology of SARS-CoV-2 amongst expectant mothers and their infants in the UK, the prevalence of vertical transmission of the virus or antibodies against the virus, and the effect, if any, on neonatal outcomes.

There is still no effective antiviral drugs and vaccines against SARS-CoV-2 yet now. This is an obsevational study, the investigators collected the clinical information and clinical outcomes of the COVID-19 patients using anti-2019-nCoV inactivated convalescent plasma.The study is to evaluate the efficacy and safety of anti-2019-nCoV inactivated convalescent plasma in the treatment of COVID-19 pneumonia.

To develop practical and effective clinical diagnosis and treatment schemes for the control of novel coronavirus pneumonia.

Critically ill patients with severe acute respiratory distress syndrome (ARDS) sometimes require treatment with veno-venous extracorporeal membrane oxygenation (ECMO) to support gas exchange. To prevent clotting of the ECMO circuit, these patients need to be anticoagulated. This protective anticoagulation also leeds to an increased bleeding risk. Most critically ill COVID-19 patients suffer from an ARDS and some require ECMO support. However, the optimal strategy and targets for the anticoagulation of these patients remain uncertain. Studies have shown that COVID-19 is associated with endotheliopathy probably leading to procoagulatory effects. On the other hand, the incidence of bleeding complications associated with this endotheliopathy is not clear and remains to be elucidated. Anticoagulation of COVID-19 patients on ECMO thus poses a challenge for clinicians. The hypothesis of the current project is that COVID-19 patients with ARDS on ECMO exhibit a higher number of bleeding complications compared to historical control patients with non-COVID-19 ARDS requiring ECMO support.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic presents a great challenge to global health. The first case was identified in December 2019 in Wuhan, China and since has infected nearly 100 million people and claimed almost 2 million lives worldwide. In response, the medical community and scientists have worked hard to develop effective therapies and guidelines to treat a wide range of symptoms including the use of the antiviral drug remdesivir, convalescent plasma, antibiotics, steroids, and anticoagulant therapy. To prevent the spread of the disease, multiple vaccines based on mRNA and DNA technologies that include inactivated viral components have been developed and millions of doses are currently being administered worldwide. Early analysis of data from the phase III Pfizer/BioNTech and Moderna vaccine trials suggested the vaccine was more than 90% effective in preventing the illness with a good safety profile (Polack et al., 2020). However, there are still many unknowns regarding the long-term safety of these newer vaccine technologies and the level and duration of immunogenicity. SARS-CoV-2 infection results in seroconversion and production of anti-SARS-CoV-2 antibodies. The antibodies may suppress viral replication through neutralization but might also participate in COVID-19 pathogenesis through a process termed antibody-dependent enhancement (Lu et al., 2020). Rapid progress has been made in the research of antibody response and therapy in COVID-19 patients, including characterization of the clinical features of antibody responses in different populations infected by SARS-CoV-2, treatment of COVID-19 patients with convalescent plasma and intravenous immunoglobin products, isolation and characterization of a large panel of monoclonal neutralizing antibodies and early clinical testing, as well as clinical results from several COVID-19 vaccine candidates. In this study, we plan to assess the effic of both vaccines on the healthcare workers. As healthcare workers begin to receive their first vaccination dosage, we will start looking for traces of antibodies within the blood and saliva. The data provided will help us determine the efficacy of the vaccine over a period of 1 year, identify any difference in efficacy amongst different populations (gender, age, and ethnicities) differences among vaccine types, demographics and follow-up on any potential side effects. We will collaborate with Nirmidas Biotech Inc. based in Palto Alto, California, a Stanford University spinoff on this project. Nirmidas Biotech. Inc is a young diagnostic company that have received several FDA EUA tests for COVID-19. We will perform IgG/IgM antibody detection by the NIRMIDAS MidaSpot™ COVID-19 Antibody Combo Detection Kit approved by FDA EUA for POC testing in our hospital site for qualitative antibody testing. We will then send dry blood spot and saliva to Nirmidas for the pGOLD™ COVID-19 High Accuracy IgG/IgM Assay to quantify antibody levels and avidity, both of which are important to immunity. The pGOLD assay is a novel nanotechnology assay platform capable of quantifying antibody levels and binding affinity to viruses. We collaborated recently with Nirmidas on this platform and published a joint paper in Nature Biomedical Engineering on COVID-19 Ab pGOLD assay (Liu et al., 2020). It is also capable of detecting antibodies in saliva samples and could offer a non-invasive approach to assessing antibody response for vaccination.

Coronavirus disease 2019 (COVID-19) is an infectious disease responsible for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The infection is highly contagious requiring restrictive and stressful measures for patients, family members and ICU healthcare providers. To avoid contagion, patient isolation has become the rule. For patients, these measures add stress to the ICU environment and deprive them of unrestricted family visits. Family members are not only left with fear but also many unanswered questions. In end-of-life situations, many family members are unable to say good-bye and unable to provide support to their loved-one throughout the process. The impact of exclusion or limited inclusion certainly needs to be explored. Moreover, ICU caregivers are having to face new challenges and to work in a unknown situation, juggling with both professional issues such as increased workload, working longer hours and safety issues, and personal issues such as child care and transport as well as family transmission of the virus. The main objective of this study is to demonstrate that the COVID-19 pandemic, as compared to seasonal flu and community acquired pneumonia, significantly increases post-traumatic stress disorder (PTSD) in family members of critically ill patients. PTSD-related symptoms will be assessed in family members using the IES-R (impact of event scale revised) during a telephone interview 90 days after ICU discharge. The IES-R is a 22-item self-report measure that assesses subjective distress caused by traumatic events. It will be compared across the three groups (COVID-19, FLU and CAP).
