1 A Cohort of Patients With Possible or Confirmed SARS-CoV-2 (COVID-19) Infection, From Diagnosis to Long-term Follow-up

SARV-CoV-2 infection was considered pandemic on March 11, 2020. The SARV-CoV-2 epidemic affected France from the beginning of March, spreading in particular from a 4-day large evangelical meeting of 2500 people on February 17 in the city of Mulhouse (North East of France). The Montpellier University Hospital has set up a clinical pathway for people suspected of being infected with SARV-CoV-2 because of signs compatible with pneumonia (screening criteria in France during the study period). This includes an emergency department, an infectious disease department dedicated to the surveillance of infected people requiring hospital treatment, and an intensive care unit for the most severe cases. The diagnosis of infection with SARV-CoV-2 was confirmed in approximately 20% of people initially referred in this special care system. The main objective of this cohorte is the collection of clinical data and biological samples from care for non-interventional research on the patients with a possible or confirmed SARS-CoV -2 infection, from diagnosis to long-term follow-up.

2 Blood Innate Biomarkers as Predictors of COVID-19 Disease Progression in Recently Infected Kidney Transplant Patients

SARS-CoV-2 induces over-production of inflammatory cytokines, and especially interleukin-6 (IL-6). The apparently strong association between blood levels of inflammaory cytokines and SARS-CoV-2 disease severity has led clinicians to evaluate the administration of steroids or anti-IL-6 antagonists in severely ill patients. As of this day, biomarkers capable of predicting clinical disease progression in Covid-19 patients with mild-to-moderate symptoms have not yet been formally identified. Identifying such markers and evaluating their predictive value may be exploited to guide patient care management, and as such forms the core objective of this proposal. Because of strong inter-individual variations in the ability of innate immune cells to produce cytokines, the hypothesis formulate and intend to test is that innate IL-6 responsiveness varies between recently infected Covid-19 patients and could predict disease outcome. To test this hypothesis, the investigator propose to follow recently infected kidney transplant patients with moderate Covid-19 symptoms. These patients stand a higher risk to progress to severe disease. The staff plan to collect a blood sample in these patients using a system whereby ex vivo cytokine production is initiated in the very same blood collection tube without prior separation and centrifugation, thus reducing labour and operator bias. After incubation with or without known innate immune stimuli, the cell-free phase from each collection-culture tube will be assayed for IL-6 content. Associations between IL-6 content and disease outcome (encephalopathy, transfer to acute care or death) will be determined in 115 Covid-19 kidney transplant patients with moderate symptoms followed in 9 centers.
