This study did not address whether patients with Takayasu arteritis and a spondyloarthritis-spectrum disorder need to be treated more aggressively, although it did note a higher rate of biologic use among these patients. However, this study implies that it may be worthwhile to screen patients with Takayasu arteritis for evidence of inflammatory bowel disease, psoriasis, and ankylosing spondylitis, although the absolute frequency of overlap between Takayasu arteritis and HLA-B27 associated diseases is low.
