Publication Metadata only Validation of ultrasound imaging for Achilles entheseal fibrocartilage in bovines and description of changes in humans with spondyloarthritis(B M J PUBLISHING GROUP, 2010) ÇELİKEL, ÇİĞDEM; Aydin, Sibel Zehra; Bas, Emine; Basci, Onur; Filippucci, Emilio; Wakefield, Richard J.; Celikel, Cigdem; Karahan, Mustafa; Atagunduz, Pamir; Benjamin, Mike; Direskeneli, Haner; McGonagle, DennisBackground Entheseal fibrocartilage (EF) derangement is hypothesised to be pivotal to the pathogenesis of spondyloarthritis. Ultrasound is useful for visualisation of the enthesis but its role in EF visualisation is uncertain. This work aimed to demonstrate face and content validity of ultrasound for EF visualisation both by bovine histological evaluation and EF imaging in spondyloarthritis. Methods Achilles enthesis of 18 bovine hindfeet was visualised using a MyLab 70 ultrasound machine. The presence of tissue with EF characteristics was documented and histological confirmation was performed on five randomly selected sections using Masson trichrome staining. Ultrasound of the Achilles tendon (AT) was performed in 19 patients with spondyloarthritis and 21 healthy controls (HC). Results The bovine EF could be visualised in all cases and seen as a thin, uncompressible, well-defined, anechoic layer between the hyperechoic bone and the hyperechoic fibrils of the enthesis both in longitudinal and transverse scans. This region corresponded to EF on histological examination. The same pattern of low signal corresponding to EF location was seen in 17/19 patients and all HC. Discontinuities of the anechoic layer around the erosions and enthesophytes were observed in the spondyloarthritis group. The thickness of the anechoic layer was not significantly different in spondyloarthritis and HC (0.5 +/- 0.1 vs 0.5 +/- 0.2 mm, p=0.9) whereas the thickness of the EF was greater in men (0.6 +/- 0.2 vs 0.5 +/- 0.1 mm; p=0.009) compared with women. Conclusion Ultrasound can visualise EF of the AT insertion, which can be abnormal in cases of spondyloarthritis. This has implications for a better understanding of enthesopathy.Publication Metadata only Methodology of a new inflammatory arthritis registry: TReasure(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2018) AKSOY, AYSUN; Kalyoncu, Umut; Tascilar, Etem Koray; Ertenli, Ali Ihsan; Dalkilic, Huseyin Ediz; Bes, Cemal; Kucuksahin, Orhan; Kasifoglu, Timucin; Alpay Kanitez, Nilufer; Emmungil, Hakan; Kimyon, Gezmis; Yasar Bilge, Nazife Sule; Akar, Servet; Atagunduz, Mehmet Pamir; Koca, Suleyman Serdar; Ates, Askin; Yazisiz, Veli; Terzioglu, Ender; Ersozlu, Emine Duygu; Tufan, Muge Aydin; Cinar, Muhammet; Mercan, Ridvan; Sahin, Ali; Erten, SUkran; Pehlivan, Yavuz; Yilmaz, Sedat; Kelesoglu Dincer, Ayse Bahar; Gercik, Onay; Coskun, Belkis Nihan; Yagiz, Burcu; Kaymaz Tahra, Sema; Aksoy, Aysun; Karadag, Omer; Kilic, Levent; Kiraz, SedatBackground/aim: The TReasure registry, created in 2017, is an observational multicenter cohort that includes inflammatory arthritis patients. This article reviews the methodology and objectives of the TReasure registry established to collect data from rheumatoid arthritis (RA) and spondyloarthritis (SpA) patients. Methodology: Fifteen rheumatology centers in Turkey will contribute data to the TReasure database. The actual proprietor of the database is the Hacettepe Rheumatology Association (HRD) and Hacettepe Financial Enterprises. Pharmaceutical companies that operate in Turkey (in alphabetical or er), Abbvie, Amgen, BMS, Celltrion Healthcare, Novartis, Pfizer, Roche, and UCB, support the TReasure registry. TReasure is a web-based database to which users connect through a URL (https://www.trials-network.org/treasure) with their unique identifier and passwords provided for data entry and access. TReasure records demographic and clinical features, comorbidities, radiology and laboratory results, measures of disease activity, and treatment data. Discussion: TReasure will provide us with various types of data, such as a cross-sectional view of the current nationwide status of the patients currently receiving these treatments, and retrospective data as much as allowed by the participating centers' records. Finally, a high-quality prospective dataset will be built over the ensuing years from patients with a new diagnosis of RA or SpA.Publication Metadata only The investigation of sacroiliitis with different imaging techniques in spondyloarthropathies(SPRINGER HEIDELBERG, 2005) ATAGÜNDÜZ, MEHMET PAMİR; Inanc, N; Atagunduz, P; Sen, F; Biren, T; Turoglu, H; Direskeneli, HPurpose: The aim of this study was to compare the value of different imaging techniques in spondyloarthropathy (SpA) patients with inflammatory low back pain. Patients and Methods: We evaluated 54 patients who fulfilled the European spondyloarthropathy classification criteria and had inflammatory low back pain. They were subdivided into two groups according to changes on plain radiography rated on a 0-4 scale according to modified New York criteria. Group A patients had at least grade-2 unilateral or bilateral changes in the sacroiliac (SI) joints, whereas group B included patients with radiologic changes not exceeding grade 0-1. Quantitative SI scintigraphy and magnetic resonance imaging (MRI) were performed to investigate the value of these techniques to the diagnosis of sacroiliitis, and the sacroiliac joint:sacrum uptake ratios were calculated. Scintiscanning was done in 80 healthy subjects to define the normal range. Results: The sensitivities of plain radiography, quantitative SI scintigraphy, and MRI were 61%, 55%, and 89%, respectively, among the patients with SpA. MRI and quantitative SI scintigraphy detected sacroiliitis in 97% and 49% of group A, respectively. In group B, these results were 76% and 66%, respectively. Conclusion: Magnetic resonance imaging is the most sensitive method for detecting acute or chronic changes in SpA patients with histories of inflammatory low back pain and normal or indeterminate findings on plain radiographs.Publication Metadata only Uveitis-related Factors in Patients With Spondyloarthritis: TReasure Real-Life Results(ELSEVIER SCIENCE INC, 2021) ATAGÜNDÜZ, MEHMET PAMİR; Bilge, Nazife Sule Yasar; Kalyoncu, Umut; Atagunduz, Pamir; Dalkilic, Ediz; Pehlivan, Yavuz; Kucuksahin, Orhan; Bes, Cemal; Akar, Servet; Cinar, Muhammet; Emmungil, Hakan; Ersozlu, Duygu; Ates, Askin; Mercan, Ridvan; Kimyon, Gezmis; Koca, Suleyman Serdar; Gonullu, Emel; Yazisiz, Veli; Tekgoz, Emre; Alpay-Kanitez, Nilufer; Erden, Abdulsamet; Kiraz, Sedat; Coskun, Belkis Nihan; Yagiz, Burcu; Ilgen, Ufuk; Karadag, Omer; Kilic, Levent; Ertenli, Ihsan; Kasifoglu, TimucinPURPOSE: Spondyloarthritis (SpA) is a group of diseases with overlapping skeletal and extra-articular features. Acute anterior uveitis (AAU) is the most common extra-articular manifestation of SpA. The relation between AAU and SpA is well defined in the current literature. Our study aims to analyze the frequency and factors associated with AAU in different forms of SpA in a large nationwide cohort of Turkish SpA patients. DESIGN: Retrospective cohort study. METHODS: The data were obtained from the TReasure database, which compiles data from records of the web-based Rheumatoid Arthritis (RA) and SpA patients treated with biological disease-modifying anti-rheumatismal drugs from different regions of Turkey. The clinical characteristics of SpA and uveitis are recorded. RESULTS: Data of the 4,297 SpA patients were included in the study. Overall, 475 of 4,297 patients (11.0%) had experienced 1 or more episodes of uveitis. SpA patients with older age (P<.001), a smoking history (P=.004), delayed diagnosis (P=.001), longer disease duration (P<.001), arthritis (P<.001), positive HLA-B27 (P<.001), a family history of SpA (P<.001), and radiographic damage (presence of sacroiliitis, syndesmophytes, bamboo spine, hip involvement) (P<.001 for all) more commonly had uveitis. On the other hand, uveitis was less prevalent in patients with psoriasis and psoriatic arthritis (P<.001 for both). CONCLUSION: Uveitis may be the key feature leading to SpA diagnosis. Patients with radiographic damage and long disease duration have an increased risk for uveitis in both male and female SpA patients. Patients with uveitis should be referred to a rheumatologist for a thorough evaluation of SpA. ((C) 2021 Elsevier Inc. All rights reserved.)
