Behçet disease of small intestine — Clinical Guidelines

Overview

Behçet disease (BD) is a chronic, relapsing systemic vasculitis characterized by oral and genital ulcers, cutaneous lesions, and multisystem involvement including the gastrointestinal tract, nervous system, and vasculature 5 7.

Diagnosis

Clinical Criteria: Recurrent oral and genital ulcers, skin lesions, and at least two additional manifestations such as uveitis, arthritis, vascular disorders, or gastrointestinal involvement 5.

Recommended Tests: Imaging studies (e.g., MRI, CT) can reveal characteristic features in affected organs like the gastrointestinal tract, nervous system, and cardiovascular system 7.

Laboratory Tests: No specific laboratory test; elevated inflammatory markers may support diagnosis 5.

Exclusion: Differential diagnosis includes other vasculitides and inflammatory conditions 5.

Management

First-Line Treatments: Corticosteroids for acute flares 5.

Adjunctive Treatments:

- Immunosuppressants: Azathioprine, cyclosporine, and infliximab have been used for refractory cases 5. - Colchicine: Effective in managing gastrointestinal and genitourinary manifestations 12. - Anticoagulants: Considered for thrombotic events 1.

Special Populations

Pregnancy: Limited data; management focuses on symptom control with caution in drug selection 5.

Comorbidities: Concomitant conditions like ankylosing spondylitis require tailored management strategies 11.

Key Recommendations

Use corticosteroids for acute exacerbations of Behçet disease symptoms (Evidence: Moderate 5).

Consider immunosuppressive agents such as azathioprine or infliximab for refractory cases (Evidence: Moderate 5).

Monitor and manage thrombotic events with appropriate anticoagulation therapy (Evidence: Weak 1).

Individualize treatment plans considering comorbidities, such as HLA B27-positive conditions (Evidence: Expert opinion 11).
