ABSTRACT
Aim to identify outdated terms and make changes to the terminology of spondyloarthritis. MATERIALS AND METHODS: At the first stage of the work, the terms divided into two categories: "outdated" definitions and terms that need to be improved or unified. Subsequently, each member of the Expert Group of Spondyloarthritis at the Association of Rheumatologists of Russia (ExSpA) presented by its own definition of the designated term or agreed with the previous term. At the next stage, the existing definitions were put together. After discussion, experts left a term that scored at least 2/3 of the votes. The special opinion of experts was recorded, whose did not coincide with the majority opinion. An open vote was conducted, when defining an "outdated" term with the unanimous decision of all group members, this term was not recommended for further clinical use. RESULTS: The work carried out allowed us to identify a number of terms that are not recommended for use in clinical practice. Number of terms are defined, which should be used when discussing the problem of spondyloarthritis. CONCLUSION: The Expert Group of Spondyloarthritis at the Association of Rheumatologists of Russia suggests using or, accordingly, not using a number of terms and their definitions in clinical practice.

AIM: To compare the clinical manifestations of ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nrAxSpA). SUBJECTS AND METHODS: A Moscow early spondyloarthritis cohort has now included 132 patients with axial spondyloarthritis, of whom 69 patients who have been followed up at least 12 months are to be involved in a preliminary analysis. The mean age at the time of inclusion in the study was 28.1±5.5 years; the mean disease duration was 24.7±15.8 months; 63 (91.3%) patients were HLA-B27 positive; 41 and 28 included patients were diagnosed with AS and nrAxSpA, respectively. RESULTS: Men were significantly more in the AS group than in the nrAxSpA group (58.5 and 32.1%, respectively; p=0.05). The patients of the two groups did not differ in main clinical parameters (the presence of arthritis and enthesitis), disease activity (BASDAI, ASDAS-CRP) and functional status (BASFI). All indicators of inflammatory activity decreased nearly 2-fold in both groups after 12 months of follow up. In 7 (25%) patients with nrAxSpA, radiologically detectable sacroiliitis (SI) developed over 12 months and the diagnosis of AS was verified. Among them, 2 (28.5%) patients had initially active SI detected by magnetic resonance imaging (MRI); 4 (57.1%) had chronic SI, and 1 (14.4%) had no pathological MRI changes. CONCLUSION: Due to the fact that the clinical manifestations of AS and nrAxSpA are comparable, it can be assumed that the latter is an early stage of AS.
