The aim of the present study was to determine the serum cytokine profile and levels of high sensitivity C-reactive protein (hsCRP)in patients with uveitis associated with Behçet's disease (BD) and to compare them with those obtained from healthy control subjects.We determined the serum concentration of interferon-γ (IFN-γ),interleukin-1β (IL-1β), IL-12p70, IL-17A,tumor necrosis factor-α (TNF-α),and hsCRP in 13 patients with active uveitis associated to BD, 24 inactive BD patients, and 20 controls. The gene discussed is IFNG; the disease is Behcet disease.
