Do clinical findings of Behcet's disease vary by gender?: A single-center experience from 329 patients

Objective: Behcet's disease (BD) is a systemic vasculitis with a significantly varying clinical course following relapses and remissions, which may involve a number of organs such as the skin, joints, lungs, and blood vessels as well as systems such as the central nervous system and gastrointestinal system. Its prognosis is known to be worse in males. There are several studies in the literature on the clinical features and gender distribution of BD. The aim of the present study was to determine the clinical characteristics of BD and the presence of a relation with gender and to investigate the correlation of our results with the current literature. Material and Methods: We retrospectively reviewed 329 patient files. The demographic features of the patients, their symptoms and findings of BD, the results of pathergy tests, the presence of any individuals in the family with BD, and HLA-B51 antigen positivity were recorded. Results: The most frequent findings were oral aphtous ulcers (100%), genital ulcers (84%), papulopustular lesions (69.9%), and joint involvement (57.4%). Vascular involvement and ocular involvement were significantly higher in males, whereas joint involvement and headache were more common in females (p<0.001, p=0.014, p<0.001, and p< 0.001, respectively). Contrary to the literature, we found that the disease had an earlier onset in individuals with a positive familial history of an oral aphthous ulcer or BD (p=0.03 and p=0.02, respectively) and that joint involvement was more common in patients with erythema nodosum (p=0.02). Conclusion: The clinical features of BD may vary between the genders. Variations exist in the results depending on the population size, the department where the study was conducted, the patient inclusion criteria, and the region where the patients live.
