Multicenter cohort of patients followed for 6 months during the pandemic in France with biocollection of sera and peripheral blood mononuclear cells
Multicenter cohort of patients followed for 6 months during the pandemic in France with biocollection of sera and peripheral blood mononuclear cellsNo data has been published concerning the incidence and prevalence of SARS-CoV-2 infection in patients with IBD and treated by IV infusion of infliximab or vedolizumab. It seems that biotherapies have a minimal impact on the severity of the viral infection but data are scarce. The objectives of the cohort are to quantify the incidence and the prevalence of SARS-CoV-2 in this population of patients, to determine clinical, demographic and biological factors associated with the risk of infection and the severity of the disease with a Multicenter cohort of patients followed for 6 months during the pandemic in France with biocollection of sera and peripheral blood mononuclear cells.
