ABSTRACT

Over the past 28 years the German Rheumatism Research Center in Berlin has initiated various epidemiological studies in which data on patients with inflammatory rheumatic diseases are collected nationwide and multicentric. The spectrum ranges from rheumatoid arthritis and spondylarthritis to connective tissue diseases and rheumatic diseases in childhood. Based on the respective scientific question, studies of different types were established. The German National Databases for adults and children annually collect cross-sectional data to map the care of patients. In two inception cohorts, adults with early arthritis and patients with juvenile idiopathic arthritis are investigated from disease onset. The long-term observational cohorts/registries RABBIT, RABBIT-SpA and JuMBO focus on the long-term efficacy and safety of biologic drugs and other targeted treatments. Rhekiss investigates women with inflammatory rheumatic diseases when trying to become pregnant, during pregnancy and postpartum. This article highlights each of these observational studies with its characteristics as well as national and international collaborations.
