Abstract

Sjögren's syndrome is a systemic autoimmune disease with a predominant involvement of exocrine glands leading to sicca symptoms. Extraglandular involvement occurs in about 40% of patients with skin, musculoskeletal, neurological and organ manifestations. Systemic vasculitic manifestations of Sjögren's syndrome can be assumed in approximately 5%-10% of patients. Leukocytoclastic or cryoglobulinemic vasculitis represent classic vasculitic manifestations of Sjögren's syndrome. In the pathogenesis of vasculitis, B-cell-driven autoimmune processes play a major role by producing autoantibodies against the Ro/SS-A and La/SS-B antigens and cryoglobulins. In patients with Sjögren's syndrome, manifestation of vasculitis, non-Hodgkin's lymphoma and glomerulonephritis, as well as positive cryoglobulins and decreased levels of complement factors, are considered negative prognostic markers. Various immunosuppressive strategies, usually in co-medication with glucocorticoids, are used for the treatment of vasculitis in Sjögren's syndrome. For refractory and severe manifestations, a B-cell-targeted therapy with Rituximab should be also considered.
