BackgroundChemokines are multifunctional mediators that control leukocyte recruitment into the inflammatory sites and enhance immune responses. It remains to be investigated which chemokines are important in Behcet's disease (BD).ObjectivesThe objective of this study was to investigate serum levels of neutrophil and lymphocyte chemoattractants in BD patients and its association with disease activity and symptoms.MethodsWe collected sera from patients with BD (n=64) and age-, sex matched healthy controls (n=21). Serum levels of chemokines were assayed for the neutrophil chemoattractants (CXCL1 and CXCL8) and lymphocyte chemoattractants (CXCL9, CXCL10, CXCL12, CXCL13 and CXCL16) by using a multiplex assay. Behcet's disease current activity form (BDCAF) and symptoms were evaluated at the time of blood collection.ResultsSerum levels of CXCL8, CXCL10 and CXCL12 were significantly higher in the BD patients than in healthy controls (p<0.001, p=0.050 and p=0.002, respectively). Serum chemokine levels were not associated with BDCAF in BD patients. But CXCL10 levels were significantly higher in patients with erythematous nodosum (EN) than in patients without EN (p=0.008). AdditionaIly, CXCL10 levels were significantly correlated with number of EN (r=0.338, p=0.006). There was no difference of serum level of CXCL1, CXCL9, CXCL13 and CXCL16 between BD and healthy controlsConclusionsSerum levels of CXCL8, CXCL10 and CXCL12 were significantly higher in the BD patients than in healthy controls. CXCL10 levels were correlated with number of EN in BD patients.Disclosure of InterestNone declared
