Cryoglobulinemia in systemic lupus erythematosus: a retrospective study of 213 patients

Abstract

Highlights • Cryoglobulinemia is frequent in SLE, but mostly asymptomatic. • Sixty-six percent of SLE patients tested positive for cryoglobulins, and 15% of the SLE patients with cryoglobulinemia developed a cryoglobulinemic vasculitis. • Features of the cryoglobulinemic vasculitis mainly involved skin, joints, and general signs. Severe manifestations of vasculitis were rare.
