title: Spondyloarthropathies-spondylarthropathies.
abstract: A committee of the European League Against Rheumatism has recommended that the term spondylarthropathy (without the letter "o" in the middle) should be avoided and is of the opinion that the use of the radical spondylo makes it clear that spondyloarthropathy is a composed word to refer to a disease that affects the spine and (peripheral) joints. The committee points out that the term spondyloarthritis (plural is spondyloarthritides) is more accurate because it means association of spondylitis with (peripheral) arthritis. The known number of subtypes of HLA-B27 continues to grow. The latest two additions are HLA-B*2710, identified in an American Caucasian family with spondyloarthropathy, and HLA-B*2711, discovered in a healthy Japanese person.
