Abstract:
Objective To re-evaluate the diagnoses of ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (nr-axSpA) and analyze the incidence and reason of misdiagnosis.Methods Patients who were previously diagnosed as AS and nr-axSpA before referrals to Peking Union Medical College Hospital (PUMCH) were re-evaluated by three rheumatologists of PUMCH according to the modified New York criteria for AS and Assessment of SpondyloArthritis international Society (ASAS) axial SpA classification criteria for nr-axSpA.Results Totally 87 prior AS patients and 53 prior nr-axSpA patients were enrolled in this study.After re-evaluation,57 patients were still diagnosed as AS and 16 patients were still diagnosed as nr-axSpA.The misdiagnosis incidences were 34.48％ and 69.81％,respectively.The misdiagnosis incidence of nr-axSpA was higher than that of AS (P ＜ 0.01).Conclusions The misdiagnosis of AS were mainly due to the misjudgment of sacroiliac joints by CT.The misdiagnosis of nr-axSpA were mainly due to the misjudgment of sacroiliac joints by magnetic resonance imaging.Moreover,the misuse of ASAS axial SpA classification criteria contributed to the misdiagnosis also.
