Prevalence of COVID-9 in patients with chronic inflammatory arthritis under treatment

Patients with chronic inflammatory arthritis (CIA) have an increased risk of infections both due to dysregulation of the immune system and immunosuppressive treatment. Preliminary evidence in our department indicates a lower rate of infection by SARS.CoV-2 in patients with CICs receiving immunosuppressive treatment than that reported for the general population (<1%). This is a cross-sectional study of a very well characterized cohort of N = 1,175 patients with CIC receiving treatment with selective immunosuppressants (ISS), both adults as in pediatric age, followed systematically in a third-level university hospital. Epidemiological and clinical data will be obtained from the electronic medical record, the shared medical record of Catalonia and through a telephone survey. The prevalence and expression will be determined. clinical practice of COVID-19 in these patients, which will allow establishing clinical practice recommendations with great scientific and social impact.
