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.
