The Patients' Beliefs Regarding the Role of Food, Mucosal Trauma, Menstruation, and Psychological Stress in the Recurrence of Behçet's Disease Symptoms.

Behçet's disease is a systemic vasculitis. Mucocutaneous involvement is the most prominent finding, but triggering factors are not well-known. We decided to assess the beliefs of patients with Behçet's disease regarding the potential role of food, mucosal injury, menstruation, and stress in the appearance of symptoms. In this cross-sectional study, 60 patients with Behçet's disease who fulfilled the International Study Group criteria for Behçet's disease and referred to the outpatient Behçet's clinic of Motahari, affiliated to Shiraz University of Medical Sciences, were included. A questionnaire was designed by the research team consisting of the rheumatologist involved in the study, two dietitians, and a psychiatrist. The patients were interviewed face-to-face to fill in the questionnaire. The assessed variables were all food categories, menstruation, psychological stress, and oral mucosal injury as the potential triggers of symptoms onset. The most common foods reported as triggers for oral ulcers were eggplant (78.3%), melon (68.3%), walnut (68.2%), and cantaloupe (66.7%). Walnut was reported by three patients (5%) as the most common trigger for genital ulcers. Nervous tension (83%) and annoying arguments (45%) were the two most common psychological stress triggers for oral ulcers. Seven patients (11.7%) reported tooth brushing, as the trigger for oral ulcers. The irregular menstrual cycle was a trigger for oral ulcers in only two patients. Food items such as eggplant, walnut and melon were common self-reported triggers for mucocutaneous lesions in patients with Behçet's disease. Nervous tension and annoying arguments were also common psychological triggers for oral aphthous ulcers.
