Uveitis represents one of the major diagnostic criteria in Behçet's disease. It is most prevalent in the countries of the Mediterranean area, including Algeria, and along the Silk Road. Clinical features include oral and genital ulcers, ocular and skin lesions, as well as central nervous system, joint, vascular, gastrointestinal, or pulmonary manifestations. Many studies have reported that Th1 immune responses are involved in the physiopathology. We have previously studied the production of IL-12 and IFN-γ, cytokine markers in the Th1 pathway involved in Behçet's disease. In our study, we investigate in vivo and in vitro IL-18 production in Algerian patients with Behçet's disease with ocular manifestations in various stages of the disease. We examined the effect of glucocorticoids on IL-18 production during the active stage of the disease. Our results suggest that IL-18 could be a good biomarker for monitoring disease activity and its regression, demonstrating the effectiveness of treatment on the underlying immunopathologic process.
