Rheumatoid arthritis

Abstract

Immune-mediated inflammatory disorders include a clinically diverse group of conditions that share similar pathogenic mechanisms. Conditions such as rheumatoid arthritis (RA), psoriasis, spondyloarthropathy, inflammatory bowel disease and connective-tissue disease are characterised by immune dysregulation and chronic inflammation. This review will focus on immunopathogenic mechanisms, aspects of early disease, co-morbidity and therapy in RA.
