1. Study identification
EU PAS Register NumberEUPAS38235
Official titleAssessment of the prophylactic effect of chloroquine/hydroxychloroquine on the COVID-19 hospitalization and mortality risk in patients with rheumatic diseases: a large-scale Italian nested case-control study
Study title acronymITA-COVID: HYDROXYCHLOROQUINE
Study typeObservational study
Brief description of the studyThis observational study will use Italian claims databases from 5 catchment areas (Lombardy, Veneto, Toscana and Lazio Regions as well as Reggio Emilia Local Health Unit) linked to COVID-19 patient registries in the same catchment areas. The aim of the present study will be to investigate the risk of hospitalization due to COVID-19 and the risk of intensive care unit admission and COVID-19 mortality in patients with rheumatic diseases treated with HCQ/CLQ as compared to other conventional DMARDs (cDMARDs). Secondary objective of this study will be to explore the risk of COVID-19-related hospitalization that is associated to recent use of HCQ/CLQ for rheumatic disease vs. non-use.
