    Vascular Behcet's disease: a comparative study from Turkey and France
    (2022-08-01) ALİBAZ ÖNER, FATMA; DİRESKENELİ, RAFİ HANER; Alibaz-Oner F., Vautier M., Aksoy A., Mirouse A., Le Joncour A., Cacoub P., Ilgin C., Saadoun D., DİRESKENELİ R. H.
    Objective Vascular Behcet\"s disease (VBD) is a systemic vasculitis involving both arterial and venous vessels of all sizes and occurring in up to 40% of patients with BD. VBD is the main cause of mortality in BD. Although commonly seen around the Mediterranean region, comparative studies in VBD are lacking. We aimed to compare the course and therapeutic approaches of VBD in two large cohorts from Turkey and France. Methods We included 291 VBD patients (female/male:63/228, mean age: 41.2 +/- 11.3 years) who were followed up in the Department of Internal Medicine and Clinical Immunology at Pitie-Salpetriere Hospital, Sorbonne University, Paris, France (n=131) and Rheumatology Division of Marmara University School of Medicine, Istanbul, Turkey (n=160). All clinical and demographical data were acquired from patient charts retrospectively. Results Smoking, family history for BD, HLA-B*51 presence and pathergy positivity were significantly higher in Turkish patients (TR), while neurologic involvement was more prominent in the French (FR) group. After a median follow-up of 77 months, 562 vascular events occurred including 440 venous events, 115 arterial events and 7 cardiac thrombi. In 79 (29%) patients, first vascular event developed before BD diagnosis and for 77 (28%) of them, vascular involvement was the presenting sign of the disease. First relapse developed in 130 (44.7%) patients after median 24.5 (1-276) months of follow-up (TR: 46.3% (n=74), FR: 42.7% (n=56), p=0.56). Survival graph revealed that FR cohort has 1.64 times increased recurrent event risk compared to TR cohort (HR=1.64 (1.1-2.44), p=.014) and although did not reach to statistical significance, IS treatment after the first vascular event decreased further vascular events (HR= 0.66 (0.43-1.01, p=.057). Conclusion Almost half of patients relapsed of VBD within 2 years after the first vascular event. Immunosuppressants decrease VBD relapses.

    The assessment of contributing factors to oral ulcer presence in Behcet's disease: Dietary and non-dietary factors
    (AVES, 2018-11-27) AKSOY, AYSUN; Iris, Merve; Ozcikmak, Ezgi; Aksoy, Aysun; Alibaz-Oner, Fatma; Inanc, Nevsun; Ergun, Tulin; Direskeneli, Haner; Mumcu, Gonca
    Objective: The aim of this study was to assess the contributing factors for oral ulcer activity in Behcet's disease (BD). Methods: Ninety-two patients with BD (F/M: 42/50, mean age: 38.7 +/- 10.02 years) participated in this cross-sectional study. Data regarding disease-related factors, smoking patterns, and self-reported dietary/non-dietary triggering factors for oral ulcer activity were collected by a questionnaire. Treatment protocol was categorized as mild and intensive groups associated with organ involvements. Results: A mild treatment protocol was more common in females (52.4% vs 20%) than in males (p=0.002). During the last three months, the number of oral ulcers in female patients was higher in the mild treatment group (6.4 +/- 6.5) than in the intensive treatment group (3.3 +/- 4.9) (p=0.045). In patients with active oral ulcers (n=63), rate of being a non-smoker was also higher in females (86.7% vs 63.6%) than in males. Daily frequency of tooth brushing was 1.2 +/- 0.8 in patients with BD, and was higher in females (1.5 +/- 0.9 vs 0.9 +/- 0.6) (p=0.001). Stress and fatigue (78.3%) were reported as the most frequent triggering factors for oral ulcer presence in patients with BD. A total of 148 different dietary factors associated with oral ulcer presence were reported in the study. Conclusion: A mild treatment protocol and being a non-smoker were found to be the contributing factors associated with oral ulcer activity in patients with BD. Being motivated for oral hygiene and being non-smokers were positive health behaviors observed in females. Irrespective of gender, stress and fatigue were defined as the most common self-reported triggering factors for oral ulcer presence in BD. In addition, the roles of some dietary factors were also reported.

    Decreasing incidence and severity of Behcet's disease: a changing trend in epidemiological spectrum possibly associated with oral health
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY) ALİBAZ ÖNER, FATMA; Mumcu, Gonca; Alibaz Oner, Fatma; Ergun, Tulin; Direskeneli, Haner
    Behget's disease (BD) is a systemic and inflammatory disorder that is mainly present along the ancient Silk Road, from the Mediterranean Sea to East Asia. A wide range of prevalence figures (0.1-420/100,000) have been reported for BD, also among Turkish populations of similar genetic background living in different countries. Recently, a decline in the incidence of BD and a change of the disease spectrum to less-severe manifestations have been reported from Japan and Korea, two genetically homogenous, affluent populations with limited immigration. It was hypothesized that a decline in infectious diseases, especially dental/periodontal infections, associated with the improvement in oral health, could be a part of these changes in the disease expression. Further epidemiological studies in other populations might demonstrate whether there is a worldwide similar trend and may provide a better understanding of the triggering factors for the onset and course of BD.
