Behçet's disease (BD) is a multi-systemic inflammatory disorder consisting of
recurrent oral aphthosis, genital ulcers, and chronic relapsing bilateral
uveitis; however, many other organs may be affected. Several pro-inflammatory
cytokines, mainly derived from Th1 and Th17 lymphocytes, seem to be involved in
different pathogenic pathways leading to development of the clinical
manifestations. On this basis, the primary aim of our study was to compare a core
set of pro-inflammatory cytokines between patients with BD and healthy control
(HC). The secondary goal was to evaluate potential correlations between these
putative circulating biomarkers, the status of disease activity, and the specific
organ involvement at the time of sample collection. Fifty-four serum samples were
collected from 46 BD patients (17 males, 29 females, mean age 45.5?±?11.3?years),
and 19 HC (10 males, 9 females, mean age 43?±?8.3?years). Twenty-five serum
cytokines (APRIL/TNFS13, BAFF/TNFSF13B, sCD30/TNFRSF8, sCD163, Chitinase3-like1,
gp130/sIL-6Rb, IFNb, sIL-6Ra, IL-10, IL-11, IL-19, IL-20, IL-26, IL-27 (p28),
IL-28A/IFN-lambda2, IL-29/IFN-lambda1, IL-32, IL-34, IL-35, LIGHT/TNFSF-14,
Pentraxin-3, sTNF-R1, sTNF-R2, TSLP, and TWEAK/TNFSF-12) were simultaneously
quantified using a Bio-Rad cytokine bead arrays. Serum concentration of sTNF-R1
(p?0.01) and sTNF-R2 (p?0.01) resulted higher in both active and inactive BD
than HC, while Chitinase3-like1 (p?0.05) and gp130/sIL-6Rb (p?0.01) serum
levels were significantly higher in inactive BD, and IL-26 (p?0.01) in active
BD than HC. No differences were observed between inactive and active BD group. In
addition, we observed that gp130/sIL-6Rb, sIL-6Ra, IL-35, and TSLP serum levels
were significantly enhanced in patients with mucocutaneous manifestations plus
ocular involvement (MO-BD) compared to subgroup with only mucocutaneous
involvement (M-BD). Our findings may suggest a signature of IL-6, tumor necrosis
factor-? as well as of Th17 response in BD patients due to increased levels of
gp130/sIL-6Rb, sTNF-R1, sTNF-R2, IL-26, respectively. This evidence could
contribute to improve the knowledge regarding the role of these citokines in the
induction of specific BD clinical features.
