Abstract

Background Behcet’s syndrome (BS) is a systemic vasculitis that may different pathogenic mechanisms leading to different manifestations, such as eye, mucocutaneous and GI disease. We started a dedicated Behcet’s clinic in 2004 and have treated over 850 patients to date.

Objectives To determine the response to therapy depending on type of organ involvement and documentation of improvement with patient reported outcomes.

Methods All patients seen at the Center complete MDHAQ, medical history, medication use, Behcet’s specific history, ethnic and demographic information forms. In addition a Behcet Syndrome Activity Score (BSAS) is also completed by all Behcet patients. These data are prospectively collected and updated each visit. Patients were divided into eye disease only, GI only, both or none groups and compared for disease activity and medication, specifically azathioprine, use. They could have mucocutaneous disease in addition to above manifestations

Results 484 patients (78% female, disease duration 4.8 (7.1) years, age 35.3 (13.8)) were analyzed. 244 patients had no eye or GI disease, 83 had eye, 111 GI and 46 both eye and GI involvement. Both groups of azathioprine treated and untreated patients showed improvement in their disease activity scores but the improvement were more pronounced for GI disease by BSAS. RAPID3 responses were more in the azathioprine treated group with eye and both eye and GI disease. Patients with no eye or GI disease did similarly with or without azathioprine.

Conclusions In this cohort of 484 Behcet patients, some treatment response differences were noted between patients with eye or GI involvement vs those who did not have these. Overall, azathioprine, led to better outcomes regardless of organ involvement. It was possible to demonstrate these improvements using patient reported outcomes, RAPID3 and BSAS, as part of routine clinical care.
