Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose: Behcet’s disease (BD) is a systemic vasculitis, whereas myelodysplastic syndrome (MDS) is a heterogeneous group of clonal hematologic disorders characterized by ineffective hematopoiesis. Some patients with BD comorbid with MDS involving trisomy 8 have intestinal lesions refractory to conventional medical therapies. We analyzed BD to evaluate the concurrence of BD and trisomy 8 and to determine whether trisomy 8 plays a role in the expression of BD associated with MDS.
Methods: Ninety-five consecutive patients were assessed for the presence of trisomy 8 in the peripheral blood. The clinical manifestation and genetic components were analyzed in patients with BD and MDS.
Results: Six of 95 patients were positive for Trisomy 8. Three of these cases were diagnosed with MDS, and they underwent bone marrow transplantation. The prevalence of MDS was as high as 50% in BD patients with trisomy 8. Gastrointestinal (GI) involvement was more common in patients with BD involving trisomy 8 than in non-trisomy8 patients (66% vs. 25%). The mean corpuscular volume (MCV) was higher in the presence of trisomy 8 than in cases lacking trisomy 8 (100.1 fl vs. 92.64 fl, P<0.01).
Conclusion: The prevalence of MDS was more higher in BD patients with trisomy 8. GI involvement seems to be an inherent feature of BD associated with MDS involving trisomy 8. When a patient with BD has increased MCV, the presence of trisomy 8 should be evaluated. Additionally, close monitoring for the possibility of MDS is necessary.
