Sponsor's own description

This epidemiological, transversal, cohort study aims to determine the potential influence of an active long-term hydroxychloroquine intake over the prevalence of a history of symptoms evocative of a COVID-19 infection in patients with a history of systemic lupus erythematosus, rheumatoid arthritis, Sjogren's syndrome or psoriatic arthritis, during the epidemic period in France. The information is gathered using a standardized questionnaire, by phone call.
