Behçet's disease associated with myelodysplastic syndromes. A case report and a review of the literature. [Case Reports, Journal Article, Review]
Cancer 1997 Jan 15; 79(2):262-8.
BACKGROUND: Behçet's disease has rarely been reported in association with myelodysplastic syndromes (MDS). Increased production of reactive oxygen species (ROS) by neutrophils has a primary role in the pathogenesis of Behçet's disease. However, decreased production of ROS by neutrophils has frequently been reported in patients with MDS. The current study was undertaken to determine the role of ROS production in a patient with Behçet's disease and MDS.
METHODS: A patient with MDS with trisomy 8 who developed Behçet's disease is described and a review of the literature of patients with Behçet's disease in MDS is presented. The production of ROS by neutrophils was investigated by luminol-enhanced chemiluminescence (CL) assay.
RESULTS: Based on a review of the literature, 10 cases of Behçet's disease associated with MDS have been reported to date. Nine patients had undergone cytogenetic analysis of bone marrow cells, 7 of whom (78%) had trisomy 8. Neutrophils taken from the authors' patient during the active phase of Behçet's disease demonstrated an increased CL response. Moreover, serum from this patient increased the CL emission of neutrophils from healthy volunteers.
CONCLUSIONS: These data suggest that trisomy 8 predisposes to Behçet's disease in patients with MDS. Furthermore, an increased ROS production by neutrophils may be associated with the diverse clinical findings in this disease. In this study, neutrophils were activated directly by serum factors.
