    Cytokine inhibitors: soluble tumor necrosis factor receptor 1 and interleukin-1 receptor antagonist in Behçet’s disease
    (Springer Heidelberg, 2005) Düzgün, Nurşen; Ayaşlıoğlu, Ergin; Tutkak, Hüseyin; Aydıntuğ, Olcay T.
    Serum levels of proinflammatory cytokines interleukin-1 beta (IL-1beta), tumor necrosis factor alpha, (TNF-alpha), and their inhibitors, IL-1 receptor antagonist (IL-1ra) and soluble TNF receptor 1 (sTNFR1), were determined by enzyme-linked immunosorbent assay in 104 patients with Behcet's disease (65 active, 39 inactive) and 40 healthy controls. The levels of IL-1beta and IL-1ra were significantly higher in both active and inactive patients than in control subjects (P < 0.01 and P < 0.01, respectively). The concentrations of TNF-alpha and sTNFR1 were found to be higher in active patients than in controls (P < 0.01 and P < 0.001, respectively). There were no significant differences in the serum levels of these cytokines and their inhibitors between active and inactive patients. Significant increases in mean C-reactive protein level and erythrocyte sedimentation rate were found in patients with active vs inactive disease (P < 0.001 and P < 0.05, respectively). C-reactive protein values correlated with erythrocyte sedimentation rate but not with cytokines or their inhibitors. Our conclusion is that elevated serum TNF-alpha and sTNFR1 seem to be important inflammatory mediators in Behcet's disease. The statistically significant increase in these levels may arise from the severity of inflammation in the tissue or organ involved.

    Serum soluble CD30 levels in Behçet's disease
    (2004) Düzgün, Nursen; Ayaslioglu, Ergin; Tutkak, Hüseyin
    Behçet's disease is associated with the inflammatory response. Several reports indicate the presence of primarily CD4+ T cells of the Th1 subtype in the inflammation process of the disease. Serum soluble CD30 (sCD30) is reported to be released from CD4+ Th2 type cells and has been suggested to be a marker of Th2 activity. In this study, serum sCD30 levels were measured in active and inactive patients with Behçet's disease, healthy controls and a group of patients with rheumatoid arthritis, typical Th1 disorder using enzyme immunoassay kit. Mean sCD30 value of 54 active patients were found significantly higher than in those of 17 inactive patients (p = 0.027), 20 healthy controls (p = 0.040) and 25 patients with rheumatoid arthritis (p < 0.001). There was a significant correlation between increased sCD30 levels and clinical activity index in active patients with Behçet's disease. High serum levels of sCD30 may reflect the activation qf CD4+ T cells or a subset of them in active BD patients. In addition to serum sCD30 levels, measurements of the Th2 cytokines may be a helpful tool for the evaluation of Th2 activity in Behçet's disease. © Copyright Clinical and Experimental Rheumatology 2004.
