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….
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.
CHICAGO—At the 2019 ACR State-of-the-Art Clinical Symposium, an annual gathering featuring talks by key opinion leaders on the most salient topics for practicing rheumatologists and healthcare providers, Jose U. Scher, MD, director of the Microbiome Center for Rheumatology and Autoimmunity at NYU Langone Medical Center, New York City, was the featured speaker. In his remarks,…
