Abstract

OBJECTIVES:
Behçet’s syndrome (BS) is a systemic vasculitis with heterogeneous clinical presentation and a relapsing disease course. The International Study Group (ISG) criteria are most often used for classification. A significant proportion of patients is classified as probable BS because they do not fulfil the criteria at initial presentation. The aim of this study is to explore clinical BS symptoms present at initial patient visit predictive of ISG criteria diagnosis during follow-up.
METHODS:
Patients classified as probable BS at initial visit were included. Follow-up ISG status (defined as meeting criteria ISG+ vs. not meeting criteria ISG-) was abstracted from last visit. Univariable logistic regression was used to screen initial visit clinical features and symptoms with follow-up ISG status. All variables that passed screening at p<0.10 were included in the final multivariable model, which was then used to create a probability risk score.
RESULTS:
189 patients were included (169 from New York and 20 from Amsterdam). 71 (37.6%) patients were classified as ISG+ during follow-up. In the final model, presence of morning stiffness, genital ulcers, skin lesions, and eye disease were associated with increased odds of ISG+, adjusting for age, symptom duration and family history. This was used to create a probability risk score.
CONCLUSIONS:
Over a third of patients with suspected or probable BS developed new manifestations over time that led to classification as ISG+ BS. The presence of morning stiffness, genital ulcers, skin lesions and eye disease at initial visit were independently associated with significantly higher odds for developing ISG+ Behçet’s during follow-up.
