چکیده انگلیسی
Uveitis is one of the major diagnostic criteria of Behçet's disease (BD), a chronic systemic inflammatory pathology with an uncertain etiology. Since uveitis is more frequent in male patients, we assessed the level and the effect of sex hormones on inflammatory responses during BD. Peripheral blood was taken from 19 patients with BD and 20 healthy subjects. Estradiol, testosterone and cortisol were measured in plasma by ELISA. Circulating mononuclear cells (PBMC) were obtained on gradient density and cultured with or without the three hormones for 24Â h at 37Â ÌC. IL-12 and nitric oxide (NO) were measured in vivo and ex vivo by ELISA and a modified Griess method, respectively. We confirmed the significantly higher in vivo and in vitro levels of NO and IL-12 in BD in comparison to controls (PÂ <Â 0.05). We also found that circulating cortisol was lower in BD while sex hormones did not show any significant difference between the groups (PÂ >Â 0.05). In vitro, NO was reduced by estradiol and cortisol and increased by testosterone in both sexes. In contrast, while IL-12 production showed the same production profile as NO in women, estradiol and cortisol failed to reduce IL-12 levels in men. Our results may explain in part the differences observed between men and women in disease clinical expression. In fact, male patients seem to have defective IL-12 down-regulation by estradiol and cortisol that increases Th1 immune responses. This may be implicated in the severe expression of BD in men.
