Serum omentin, resistin and tumour necrosis factor-α levels in Behcet patients with and without ocular involvement

The objective of this study was to evaluate serum omentin, resistin and tumour necrosis factor-alpha (TNF-alpha) levels in Behcet disease (BD) patients with and without ocular involvement, as well as control subjects. Omentin, resistin and TNF-alpha levels were assessed in the plasma of 51 BD patients and compared with those of 24 control subjects. The plasma resistin and TNF-alpha levels were significantly higher in the BD patients than in the control group (p = 0.028 and p = 0.011, respectively), whereas the plasma omentin level was significantly lower in BD patients than in the control group (p = 0.035). In the ocular BD, non-ocular BD and control groups, the omentin levels were 8.9 +/- 4.65, 8.6 +/- 3.61, and 12.4 +/- 6.24 ng/mL; resistin levels were 0.29 +/- 0.21, 0.24 +/- 0.2 and 0.15 +/- 0.45 ng/mL; and TNF-alpha levels were 25.45 +/- 3.65, 24.03 +/- 2.49 and 21.93 +/- 4.86 ng/mL, respectively. Omentin/resistin and TNF-alpha/omentin ratios were more significant parameters in the demonstration of the differences in the groups; the former was lower and the latter was higher in the patient groups (p = 0.001 and p = 0.002, respectively). We demonstrated that the plasma omentin level and omentin/resistin ratio were decreased, whereas the resistin and TNF-alpha levels and TNF-alpha/omentin ratio were increased in BD patients. These ratios may be used in the presentation of deviation in the inflammatory and anti-inflammatory balance in BD.
