Khan and colleagues first described this condition in 1985, referring to it as “spondylitic disease without radiologic evidence of sacroiliitis” [<span>1</span>]. Although the concept of nr-axSpA had been recognized prior to this description, the 2009 Assessment of Spondyloarthritis International Society (ASAS) classification criteria brought the entity to the forefront of clinical practice and research. According to these criteria, individuals younger than 45 years with chronic low back pain lasting more than 3 months may be classified as having axial spondyloarthritis if they fulfill either the clinical arm, requiring at least two spondyloarthritis (SpA) features, or the imaging arm, requiring at least one SpA feature in conjunction with imaging evidence of sacroiliitis [<span>2</span>]. The prevalence of nr-axSpA in the United States is estimated to be approximately 0.35%, compared with a combined axial SpA prevalence of 0.9%–1.4% [<span>3, 4</span>]. In contrast, a survey-based study from Japan estimated the prevalence of radiographic axSpA (r-axSpA) to be 0.0026%, with an even lower prevalence of nr-axSpA at 0.0006% [<span>5</span>].</p><p>Historically, axial SpA has been regarded as a predominantly male disease; however, more recent data suggest that the male-to-female ratio has narrowed, with several studies reporting near equivalence, particularly within nr-axSpA cohorts [<span>6</span>]. Sex-based differences in clinical presentation have also been observed, with women more likely to report widespread pain, including cervical and upper thoracic symptoms that may not meet traditional definitions of inflammatory back pain [<span>7</span>]. Women additionally tend to exhibit less radiographic damage, a factor that may contribute to the longer diagnostic delays consistently reported among female patients compared with males [<span>7</span>].</p><p>Findings from large observational cohorts have further clarified the clinical characteristics of nr-axSpA. In the German Spondyloarthritis Inception Cohort (GESPIC), patients with early nr-axSpA demonstrated active inflammatory disease, with radiographic progression associated with HLA-B27 positivity, elevated C-reactive protein (CRP), and the presence of baseline MRI osteitis [<span>8</span>]. The French Devenir des Spondylarthropathies Indifférenciées Récentes (DESIR) cohort showed that most patients with early inflammatory back pain remain non-radiographic over long-term follow-up, with women exhibiting greater pain burden and lower inflammatory markers than men [<span>9</span>]. Data from the Corrona registry in the United States similarly demonstrated sex- and inflammation-related differences, identifying a higher proportion of women, lower CRP levels, and l","PeriodicalId":14330,"journal":{"name":"International Journal of Rheumatic Diseases","volume":"29 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1756-185x.70637","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147633543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
