Summary
Primary Sjögren's Syndrome (pSS) is an autoimmune disorder characterized by keratoconjunctivitis sicca and xerostomia. In addition, various extraglandular manifestations may develop. Several immunomodulating agents have been attempted in the treatment of pSS without achieving satisfactory results. Currently, there is no approved systemic treatment for pSS. Dysfunction of regulatory T (Treg) cells has been detected in diverse autoimmune diseases, which can be promoted by interleukin-2 (IL-2). The investigators hypothesized that low-dose IL-2 could be a novel therapy in active pSS patients. This clinical study will test the efficacy and safety of low dose IL-2 treatment in pSS. The investigators perform a single-centre, double-blind pilot trial with hrIL-2 in pSS. The investigators evaluate the effectiveness and safeness of low-dose hrIL-2 for primary Sjögren's Syndrome by randomized controlled study (hrIL-2 (N = 30) versus placebo group (N = 30)).
