*2.3.7 Intravenous immunoglobulin*

Therapeutic intravenous immunoglobulin (IV IG) mostly consists of human polyspecific immunoglobulin G. IV IG has been used in patients with systemic lupus erythematosus and was shown to reduce the activity of the disease [85]. IV IG may be used in cases of refractory neuropsychiatric lupus [83] and in lupus myocarditis [86].
