EIRA (Epidemiological Investigation of Reumatoid Arthritis) aims to investigate possible risk factors of rheumatoid arthritis (RA), a chronic disease causing severe suffering and functional disability. It is the first, and as of yet, the most ambitious project of its kind, including both genetic and environmental factors.

The main goal of this research project is to increase the understanding of which factors contribute to the development of this disease. The knowledge gained through this study can be of use in both the treatment and the prevention of this chronic disease.

The EIRA study is based at Karolinska Insitutet in Stockholm, Sweden and is a collaborative study consisting of research groups from both the Institute of Environmental Medicine and the Institute of Medicine, located at the Karolinska University Hospital.
