Cases of AS patients with psoriasis were recruited from a prospective AS registry of the same center. Demographics, laboratory findings, and radiologic characteristics were assessed.Results: A total of 69 PsA patients were identified. In PsA patients, spondylitis (46.4%) was the most common form. Compared to AS patients with psoriasis, PsA patients with radiographic axial involvement were older (50.9 vs. 32.4 years; p &lt; 0.001) and showed greater peripheral disease activity (peripheral arthritis 78.1 vs. 12.5%, p &lt; 0.001; enthesitis 50.0 vs. 6.3%, p = 0.003). AS patients with psoriasis presented a higher rate of HLA-B*27 positivity (81.3 vs. 17.2%; p &lt; 0.001) and a more frequent history of inflammatory back pain (100.0 vs. 75.0%; p = 0.039) than PsA patients with radiographic axial involvement. Significant proportions of PsA patients with radiographic axial involvement had cervical spine involvement (10\/18, 55.6%) and spondylitis without sacroiliitis (10\/23, 43.5%).Conclusions: We demonstrate that axial involvement is common in Korean PsA patients, and its characteristics can be distinct from those of AS.<\/jats:p>","DOI":"10.3904\/kjim.2023.044","type":"journal-article","created":{"date-parts":[[2023,12,8]],"date-time":"2023-12-08T02:54:25Z","timestamp":1702004065000},"page":"184-193","update-policy":"https:\/\/doi.org\/10.3904\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Characteristics of patients with psoriatic arthritis in Korea: focusing on axial involvement"],"prefix":"10.3904","volume":"39","author":[{"given":"Hanna","family":"Park","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Hyun","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung-Ki","family":"Kwok","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Hyeon","family":"Ju","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wan-Uk","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Hwan","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6873-6629","authenticated-orcid":true,"given":"Jennifer Jooha","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2270","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/0049-0172(73)90035-8"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1136\/annrheumdis-2018-213334"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2006.054288"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.3899\/jrheum.210434"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1056\/nejmoa2022516"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1136\/annrheumdis-2020-218808"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s00296-015-3365-3"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s002960050109"},{"key":"ref9","first-page":"418","volume-title":"Clinical features of Korean patients with psoriatic arthritis","author":"Choi","year":"2008"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(18)30830-4"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1002\/art.21972"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1038\/s41584-018-0006-8"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/kez629"},{"key":"ref14","first-page":"361","volume-title":"Evaluation of diagnostic criteria for ankylosing spondylitis.
