Effect of Colchicine on Th1 and Th17 Cytokines, Cytokine Receptors, and Chemokine Gene Expression Profiles in Behçet's Disease
Gene expression in behçet patients
Objective: Colchicine has been used in recent years as an effective drug for controlling attacks in Behçet’s disease. In the present study, we investigated expression levels of IL1R, IL2R, IL12RB, IL23R, IL17, CXCR3, CXCR10 and IL8 genes in patients with active and inactive Behçet’s disease. We also evaluated how colchicine use in patients with active and inactive disease affected these genes and evaluated their role in the etiopathogenesis of the disease.
Methods: Thirty-five patients who were diagnosed with Behçet’s disease according to the International Working Group criteria (28 with active disease, 7 inactive) and were taking colchicine were enrolled in the study. Twenty healthy subjects were included as a control group. Expression levels of the IL1R, IL2R, IL12RB, IL23R, IL17, CXCR3 ,CXCR10 and IL8, genes were evaluated.
Results: Expression levels of CXCR3 and IL23R were significantly lower in patients with active Behcet's disease when compared with the inactive disease and control groups. However, the differences in CXCR3 and IL23R expression between the inactive Behçet’s patient group and the control group were nonsignificant. Expression levels of the other genes did not differ statistically between the active Behçet’s patients, inactive Behçet’s patients, and control subjects.
Conclusion: While the expression levels of the CXCR3 and IL23R genes in active Behçet’s patients were statistically lower than controls, there was no statistical difference between active and inactive Behçet’s patients or controls in terms of IL1R, IL2R, IL17, IL12RB, CXCR10 and IL8, gene expression levels. This study may form the basis for further studies to determine the molecular mechanism of colchicine in the treatment of Behçet's disease.
