Description détaillée
This is a multicenter, single-arm clinical trial designed to evaluate the efficacy and safety of ustekinumab in patients with intestinal Behçet's syndrome complicated by myelodysplastic syndrome (MDS). A total of 8 patients with intestinal Behçet's syndrome and concomitant MDS will be enrolled. Prior to enrollment, all patients will discontinue any previous biologic agents. Ustekinumab will be administered subcutaneously at a dose of 90 mg at weeks 0, 4, and 8, followed by a maintenance dose of 90 mg every 12 weeks (every 3 months). All patients will be followed for a total of 24 months.
Clinical manifestations, inflammatory biomarkers, and endoscopic findings will be documented throughout the study period. Concomitant medications will be recorded, and adverse events will be systematically monitored to evaluate the efficacy and safety of the treatment.

Changes of Behcet's Disease Current Activity Form (BDCAF) score of patients
Délai: Week 24
|
Clinical manifestations are recorded at enrollment and at week 24, and changes in the BDCAF score from baseline to week 24 are evaluated.
The score of BDCAF ranges from 0 to 12, with higher scores indicating greater severity.

Changes of Disease Activity Index for Intestinal Behcet's Disease (DAIBD) of patients
Délai: Week 24
|
Intestinal-related clinical manifestations are documented at enrollment and at week 24.
Changes in the DAIBD score from baseline to week 24 are evaluated.
The score of DAIBD ranges from 0 to 295, with higher scores indicating greater severity.
