COVID-19 Clinical Trials and Expanded Access

This study will investigate the security and efficacy of a daily low dose of hydroxychloroquine and Bromhexine, in preventing the development of the disease from COVID-19 in Health Care Workers at a National Institute of Health In Mexico City.

assess the safety and effectiveness of using low-flow extracorporeal membrane oxygenation(CO2 removal) driving by CVVH machine in the severe NCP patients

Hospitalized patients with COVID-19 will be included in the study in centers around Poland. After the hospitalization, a short questionnaire will be completed, including pre-hospitalization diagnoses, pre-hospitalization medications, clinical status on admission, the course, complication and the duration of hospitalization. The questionnaire will be available in paper form and on-line.

Due to the COVID-19 global health pandemic, many people are likely experiencing increased stress. The well-being of physicians in training may be significantly impacted by this pandemic. Meditation is a self-management strategy that can be utilized by anyone to assist with the management of stress. Meditation mobile applications, such as the "Calm" app, can be used to help manage stress, especially during this uncertain time. The investigators propose a prospective evaluation of perceived stress, anxiety, burnout and sleep disturbance in the house staff at Banner University Medical Center Phoenix, with the use of the mobile meditation app, "Calm." The investigatros additionally want to evaluate the feasibility of using the mobile app, including looking at adherence to use of the app and physician satisfaction with use of the app.

Quarantine is an unpleasant experience : separation from loved ones, loss of freedom, uncertainty about infection status, boredom. It may lead to negative mental health consequences and thus the emergence of anxiety and depressive symptoms. From March 17th, 2020 to May 11th 2002, the French government has implemented national containment measures due to the Covid-19 epidemic. Although there are data on the psychological impact and experience of quarantine measures in people who have been infected or suspected of being carriers of certain pathogens (e.g. Ebola), there are no data on such impact in the French population and quarantines lasting longer than 21 days. Investigators therefore propose to conduct a human and social sciences study in order to better understand the current situation

Facing the unusual situation imposed by the coronavirus disease, the aim of this study is to evaluate the risk and effects of less frequent hemodialysis on prevalent patients

During the new COVID-19 pandemic physicians all over the world have faced different challenges .Oxidative stress is a probable cause of multi organ failure in this setting which never has been evaluated in COVID-19 infection to the best of knowledge.Present study aimed to evaluate oxidative stress marker and redox system status in different COVID-19 patients regarding the severity of involvement.

This study aims to observe the long-term health-related quality of life (HRQOL) and physical performance in individuals hospitalized due to a COVID-19 infection. Therefore, data is extracted from a study-site standard aftercare program which has been adjusted for this patient population. This comprehensive aftercare program includes education sessions and physical exercise. A second aim is to observe adherence and feasibility to the program and if indicated compare the clinical data and outcomes from patients following the program with patients denying to participate in guided exercise and education sessions. It is expected that patients hospitalized due to COVID-19 infection show a reduction in physical performance and HRQOL directly after discharge. The severity of illness is hypothesized to be associated with a reduction as well in HRQOL and physical performance after one-year post-discharge.

SARS-CoV-2 belong to beta-coronavirus family and its transmission route and symptoms follow those of all community-acquired coronaviruses. The main difference of the novel Coronavirus is the higher mortality rate, that is around 3%. Death rate is over 1% only for patients over 50 years old, whereas until 40 years old is under 0,4%. No fatalities are declared among children under 10 years old to date. Death rate is almost double for male rather than female. This distribution of mortality rate according to age of infected patients could be only partially ascribed to other comorbidities in addition to great age. In fact, patients with no pre-existing conditions have however a case fatality rate of 0,9%. The almost null rate of severe illness in children and generally in patients younger than 40 years old is quite un-explicable. Infant, children and young people could be infected but infection is rapidly self-limited or without symptoms. Older patients undergo severe lung injury as consequence of an immune response that is late in coming. Possible explanation of these phenomena could be something, which assure ability to prompt response to SARS-CoV-2 in younger people independently from the novelty of the virus itself. It would seem to be that younger people are already sensitized to the antigens of the virus without a previous contact. This immunity is not really specific, but "partially specific" for many antigens of the virus, however able to limit the infection in the organism. Something stimulated the immune system and it scattered immunity against more and more antigens present. Children are the age group mostly exposed to all community-circulating viruses. This immunity is not persistent but progressively fade out. It protects from the age of two, when the hypothetical stimulation occurs, to the fifth decade because of its slow decrease. The only external stimulation, which healthy people receive are vaccines. All vaccinations and especially tetanic, diphtheria toxoids and inactivated bacteria as pertussis could stimulate immune system. They develop the specific immunity but generate also a sprouting immunity against antigens in transit, as coronaviruses and other community-circulating viruses. The developed immunity gives some protection against multiple viral infection for years until the natural fade out. After the fifth decade, that immunity is slower to be recall and reactivated. Additionally, transplant recipients and HIV infected patients, which have an immune system inhibited, unexpectedly, do not seem to suffer the worst complications of SARS-CoV-2 infection. An immune system imbalance could be play a pivotal role during the reaction to the virus, limiting destructive consequences of excessive inflammation. According to the medical hypothesis on which the protocol is based on, young people could benefit from a functional adaptation of innate immune cells induced through epigenetic reprogramming and, especially, a pre-existing "partially specific" immunity to the community viruses caused by "bystander effect" of preceding vaccinations. In this study, we will explore the main differences existing among patients infected by SARS-CoV-2 who experience the illness at different degree of severity. We suppose to recognize different populations of patients, each one with a specific immunological pattern. It could differ in terms of cytokines, soluble factors serum level and immune cells activity both of the innate compartment and of the acquired one. The proof of a role of these immunological phenomena in the pathogenesis of Covid-19 are bases for implementation of therapeutic immunomodulatory treatments. In addition, the definition of an immunological risk profile could tailor established therapies to each kind of patient.

This study aims to investigate the quality of life of COVID-19 patients after recovery and discharge from the hospital. Patients following-up at the PWH outpatient clinics will be enrolled for further evaluation via telephone follow-up at one, three, and six months after hospital discharge. SF12, EQ-5D-5L and work status standardized quantitative assessments of quality of life will be implemented via telephone follow-up at these time-points. Previous studies of patients infected with SARS-CoV-1 in 2003 at PWH showed that significant numbers of recovering patients had impaired long-term health status. It is important to see if these same problems also afflict patients infected with the SARS-CoV-2 virus (the novel coronavirus which causes COVID-19).
