Clinical Characteristics and Outcomes of Mexican Patients With Behçet’s Syndrome

Abstract

ObjectiveThe aim of this study was to describe the clinical characteristics and outcomes of Mexican patients with Behçet syndrome (BS) from a single center.MethodsThis medical records review study included patients with established BS diagnosis, followed up in a tertiary care center in Mexico City from 2000 to 2020. Demographics, clinical characteristics, laboratory and imaging studies, disease activity, damage, treatment, and outcomes were assessed and compared according to sex and with other international cohorts. Descriptive statistics were used, and differences between groups were evaluated using the χ2 or Mann-Whitney U tests.ResultsThirty-eight patients were included, 23 (60%) women and 15 (40%) men; the median age at BS diagnosis was 33 years (range, 24–39 years). The most frequent manifestations at diagnosis were recurrent oral and genital ulcers in 34 (89%) and 29 (76%), respectively, musculoskeletal in 21 (55%), and cutaneous in 15 (39%). The most frequent phenotype was the joint involvement. Treatment comprised prednisone in all, colchicine (24 [63%]), pentoxifylline (12 [32%]), and thalidomide (10 [26%]). During a median follow-up time of 12.5 years (range, 7–23 years), relapses were frequent (97%), severe infections were present in 5 patients (13%), and 2 patients (5%) died due to sepsis and pneumonia. Men showed a higher frequency of arterial hypertension (47% vs. 13%, p = 0.03) and thrombosis (20% vs. 0, p = 0.05), and a lower frequency of genital ulcers (40% vs. 78%, p = 0.03) than women.ConclusionsThis cohort of Mexican patients with BS showed a predominance of female sex, joint involvement phenotype, frequent relapses, and favorable outcomes. Differences in comorbidities and clinical manifestations were identified according to sex.
