Establish a COVID-19 biorepository to aid in developing our knowledge of the disease.

The proposed study is designed to investigate if and how pregnant women infected withCoronavirus Disease-19 (COVID-19) infection go on to develop long-term immunity. InDecember 2019, a group of people in Wuhan, China presented with symptoms of a pneumoniaof an unknown cause that led to the discovery of a new coronavirus called COVID-19.COVID-19 has caused a global pandemic with 7,140,000 confirmed cases and 418,000 deathsas of 13th June 2020. In the United Kingdom (UK), there have been 294,000 cases and41,662 deaths as of 13th June 2020. In humans, this infection primarily involves theupper part of the lungs, but it can also affect other organs. It causes mild symptoms inthe majority of people affected but some people can have severe infections, with someeven requiring critical care in hospital. During Severe acute respiratory syndrome(SARS), a previous coronavirus epidemic, pregnant women were disproportionately affectedwith severe illness. Understanding how the immune system responds long-term to thisinfection may hold the key to developing better vaccines and efficient treatment plans.Specialised immunity develops when individuals are infected by this and other viruses.The investigators of this study propose that, in pregnancy, this specialised immunity maynot behave effectively. This may affect their ability to develop long lasting immunityand make them more vulnerable to re-infection. In this study, the investigators aim torecruit patients across 6 groups including COVID-19 newly infected pregnant women, andpeople with differing illness severity, mild to moderate, severe/critical, no infection(controls), as well as pregnant women with influenza and those receiving influenzavaccine. The study team will compare COVID-19 in pregnancy with non-pregnant infected andwith influenza infected and vaccinated pregnant women. The study team will consentpatients in all of these groups to provide a series of blood samples at different timepoints in a 12-month period.

In this study, providing access to physiotherapy applications by telerehabilitationmethod and the effectiveness of this application will be examined for patients who haveundergone lung surgery in the early postoperative period during the pandemic process inwhich social isolation continues.

This is a phase I trial followed by a phase II randomized trial. The purpose of phase Istudy is the feasibility of treating patients with acute respiratory distress syndrome(ARDS) related to COVID-19 infection (COVID-19) with cord blood-derived mesenchymal stemcells (MSC). The purpose of the phase II trial is to compare the effect of MSC withstandard of care in these patients. MSCs are a type of stem cells that can be taken fromumbilical cord blood and grown into many different cell types that can be used to treatcancer and other diseases. The MSCs being used for infusion in this trial are collectedfrom healthy, unrelated donors and are stored and grown in a laboratory. Giving MSCinfusions may help control the symptoms of COVID-19 related ARDS.

This study aims to determine how long COVID-19 neutralizing antibodies can be detected inan elderly institutionalized population presenting fragility factors.This study also aims to stratify seroconversion by immunological profiles of the elderlypatients residing in the EHPAD. This stratification requires the measurement ofimmunological marker levels already described in immunosenescence and also involved inthe development of certain chronic infectious diseases more common in the elderlypopulation. This analysis will enable the investigators to describe an immunological,clinical and biological profile representing a patient who has developed an immunityagainst COVID 19. It will also help the investigators to understand the differentmechanisms leading to a reduced immune response after a potential administration of avaccine. Finally, it will help describe the immune profiles of elderly residents whopresented with non-severe forms of COVID-19.

The study explore the relationship between COVID-19 and the induction of autoimmunediseases.

The purpose of the study is to evaluate the presence of early vascular aging 6 months and12 months after COVID-19 infection.

Prospective, single center, randomized, open label, parallel group, 2-arm study assessingthe clinical benefit in term of enhancement of overall response rate of Isatuximab incombination with CellProtect as compared to Isatuximab for the treatment of patients withnewly diagnosed multiple myeloma who are eligible for stem cell transplantation (SCT) asmaintenance after SCT.

The study investigates how the COVID-19 pandemic has impacted the psychological,financial, physical, and social well-being of adolescent and young adult (AYA) cancerpatients and survivors. AYA cancer survivors have inferior long-term survival compared tothe general population, and the negative impact of the global COVID-19 pandemic may beeven higher in this vulnerable group. The information gained from this study may providean opportunity to determine the self-reported COVID-19 specific psychological distress inAYA cancer survivors, and may lead to the development of a targeted intervention toimprove physical and psychosocial health for AYA cancer patients and survivors.

NORPLASMA COVID-19 includes both the production of convalescent plasma from approvedblood donors who have recovered from covid-19 (coronavirus disease 2019), and clinicalstudies to evaluate efficacy and safety of the treatment, as recommended by Europeanhealth authorities. Patients who receive convalescent plasma in a clinical setting willbe invited to participate in the monitoring study NORPLASMA MONITOR, where clinical dataabout safety and effect on clinical parameters including virus load and recovery timewill be collected and compared to european patients in a common database for the Europeancountries. The treated patients can be compared to a historical control group.
