Materials and Methods: The study included adult patients with psoriasis who underwent clinical examination, laboratory tests and ultrasound examination of the entheses. The enthesitis ultrasound scores (BUSES, MASEI, GUESS) were evaluated; the presence of OMERACT-defined enthesitis was also recorded for each scan site. Results: The study included 16 (57.1%) patients with PsA and 12 (42.9%) patients with psoriasis, with an increased average body mass index (29.3 kg\/m2). Compared to psoriasis patients, PsA patients had a higher prevalence of nail psoriasis (68.8% compared to 33.3%; p = 0.063). There were no significant differences regarding the clinical examination of entheses between patients with psoriasis and patients with PsA (p = 0.459). Ultrasound scores, BUSES, GUESS and MASEI proved to have statistically significant higher median values in PsA patients compared to psoriasis patients. Compared to psoriasis patients, PsA patients had a significantly higher prevalence of OMERACT-defined enthesitis of the quadriceps tendon and inferior patellar ligament (both 81.3% compared to 25.0%, p = 0.003). Clinical examination of the lateral epicondyle and of the superior patellar ligament was consistent with their ultrasound examination (\u03ba = 0.357, p = 0.043, respectively, \u03ba = 0.404, p = 0.008). Conclusions: Clinical enthesitis scores do not differ between psoriasis and PsA patients. All analyzed ultrasound scores are significantly higher in patients with PsA. OMERACT-defined enthesitis has the ability to discriminate sonographic enthesitis between the two subgroups for bilateral quadriceps and inferior patellar tendon enthesitis. Bilateral ultrasound damage of entheses can suggest a PsA diagnosis.<\/jats:p>","DOI":"10.3390\/medicina58111557","type":"journal-article","created":{"date-parts":[[2022,10,30]],"date-time":"2022-10-30T09:01:42Z","timestamp":1667120502000},"page":"1557","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Ultrasound Enthesitis in Psoriasis Patients with or without Psoriatic Arthritis, a Cross-Sectional Analysis"],"prefix":"10.3390","volume":"58","author":[{"given":"Mihaela","family":"Agache","sequence":"first","affiliation":[{"name":"Department of Internal Medicine and Rheumatology, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 050474 Bucharest, Romania"},{"name":"Clinical Center of Rheumatic Diseases, 030167 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8236-1242","authenticated-orcid":false,"given":"Claudiu C.","family":"Popescu","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Rheumatology, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 050474 Bucharest, Romania"},{"name":"Clinical Center of Rheumatic Diseases, 030167 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liliana","family":"Popa","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Rheumatology, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 050474 Bucharest, Romania"},{"name":"Department of Dermatology and Allergology, Elias Emergency University Hospital, 011461 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u0103t\u0103lin","family":"Codreanu","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Rheumatology, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 050474 Bucharest, Romania"},{"name":"Clinical Center of Rheumatic Diseases, 030167 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1016\/j.semarthrit.2017.12.008","article-title":"Enthesitis: Enthesitis: A hallmark of psoriatic arthritis","volume":"48","author":"Kaeley","year":"2018","journal-title":"Semin Arthritis Rheum."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"154","DOI":"10.3899\/jrheum.110845","article-title":"The ClASsification for Psoriatic ARthritis (CASPAR) criteria\u2014A retrospective feasibility, sensitivity, and specificity study","volume":"39","author":"Tillett","year":"2012","journal-title":"J.
