AB0808 Costovertebral, Costotransverse, Sternoclavicular and Manubriosternal Joint Involvement in Spondyloarthritis: Preliminary Results of Single Centre Experience

Background Costovertebral (CV), costotransverse (CTr), sternoclavicular (SC) and manubriosternal (MS) joint involvements may be in spondyloarthritis (SpA). However, the radiological clinical characteristics of these need further assessment. Objectives In this study, we aimed to determine CV, CTr, SC, MS SpA patients. Methods patients (searched from hospital data-processing system according ICD-10 having M07 (enteropathic arthropathies), M45 (ankylosing spondylitis (AS)), M46 (other inflammatory spondylopathies) and/or M48 codes) who have been requested a chest computed tomography (CT) for any reason between January 2010 December 2020 included retrospective cross-sectional analysis. Chest CT reports were reviewed, SC or involvement attributed accepted as positive involvement. Demographic/clinic data including smoking status, disease (duration, drug history, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Functional (BASFI), Metrology (BASMI) other related parameters) at time scan collected analyzed. Results After confirmation diagnoses among 1700 patients, total 339 study. 244 diagnosed with ankylosing (AS), 66 psoriatic arthritis (PsA), 14 enteropathic arthritis, 13 peripheral SpA, 2 non-radiographic axial SpA. According reports, number changes joints on thoracic 44. Of 42 AS (95,5%), 1 PsA (2,3%), (2,3%) 39 9 5 joints, 3 CTr affected. Joint (17%) higher than patient groups (p<0.001). group, Schober’s test, expansion significantly lower negative group.

As is preliminary CTs will re-evaluated by our radiologist, capable report unbiased results. References [1]Cerrahoglu L, Unlu Z, Can M, et al.
