Disease activity was measured using the Beh\u00e7et\u2019s Syndrome Activity Scale (BSAS) and the Beh\u00e7et\u2019s Disease Current Activity Form (BDCAF) with quality of life measured by the Beh\u00e7et Disease Quality of Life (BDQOL) form. One-way ANOVA, t-tests, and multivariate regression analyses were performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results.<\/jats:title><jats:p>Mean age did not differ between sites; however, more women were seen in the United States versus in Turkey (p &lt; 0.001), and disease duration was longer in the United States (p = 0.02). Organ manifestations were similar for oral and genital ulcers, skin disease, arthralgia, eye disease, and thrombosis. However, more gastrointestinal (p &lt; 0.001) and neurologic disease (p = 0.003) was seen in the United States. BSAS and BDCAF scores were worse in the United States compared to Turkey (p = 0.013 and &lt; 0.001, respectively). Worse mean BDQOL scores were observed at the NIH compared to Istanbul (not significant). Multivariable regression models showed worse scores in ethnically atypical patients for BSAS and BDCAF (p = 0.04 and p = 0.001), American patients for BDCAF (p = 0.01), older age for BDCAF (p = 0.005), and women for BDQOL (p = 0.01).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion.<\/jats:title><jats:p>Demographic and clinical manifestations of BS differ between sites with higher disease activity in the United States compared to Turkey. Referral patterns, age, sex, ethnicity, and country of origin may be important in these differences. These observations raise the question of whether pathogenic mechanisms differ in Turkish and American patients.<\/jats:p><\/jats:sec>","DOI":"10.3899\/jrheum.131227","type":"journal-article","created":{"date-parts":[[2014,6,16]],"date-time":"2014-06-16T13:30:45Z","timestamp":1402925445000},"page":"1379-1384","source":"Crossref","is-referenced-by-count":47,"title":["Beh\u00e7et
