These conditions are distinct in that they involve axial joints, are associated with the HLA-B27 haplotype, have a frequent family history of these diseases, and are rheumatoid factor-negative. Traditionally, the specifically named spondyloarthropathies included ankylosing spondylitis, psoriatic arthritis, the arthropathy of inflammatory bowel disease (IBD), and reactive arthritis (previously referred to as Reiter disease).
