HLA-B27 may be a phenotypic expression of axial spondyloarthritis (SpA), according to a large international study. The study found patients with axial SpA who were positive for HLA-B27 had more severe radiographic damage than those who were negative for HLA-B27, and three quarters of study patients with ankylosis spondyloarthritis were HLA-B27 positive.
ATLANTA—Research into possible genetic drivers of the axial spondyloarthritis (axSpA), including the role of the genetic marker HLA-B27, is advancing, John D. Reveille, MD, professor and vice chair of medicine at the University of Texas McGovern Medical School, Houston, told attendees at the 2019 ACR/ARP Annual Meeting. Dr. Reveille delivered the Philip Hench, MD, Memorial…
It’s often said the eyes are the window to the soul, and in the case of ankylosing spondylitis and other spondyloarthropathies, one can also say the eyes are the window to systemic disease. Although uveitis occurs in approximately 2–5% of patients with inflammatory bowel disease, 6–9% of patients with psoriatic arthritis and 25% of patients…
The mechanistic link between human leukocyte antigen B27 (HLA-B27) and ankylosing spondylitis (AS) is one of the great enigmas in rheumatology. The introduction of biological therapies that target tumor necrosis factor (TNF) or the interleukin (IL) 23/IL-17A axis has had a major impact on the quality of life for many patients with AS, and one…
Understanding how human leukocyte antigen (HLA) class I molecule B27 promotes spondyloarthritis has intrigued researchers for four decades. Although the association between the single gene variant HLA-B27—specifically some of its subtypes—with ankylosing spondylitis (AS) is particularly strong, how HLA-B27 directly influences disease development has not yet been clearly explained, although hypotheses continue to be generated….
New research reports on the increased sensitivity of human-HLA-B27 transgenic rat bone marrow monocytes to TNF-α stimulation and osteoclast differentiation. (posted June 27, 2013)
