High-dose intravenous immunoglobulins for lupus nephritis--a salvage immunomodulation

Abstract

Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease with a great diversity of clinical manifestations which is difficult to manage. IVIGs represent promising immunoregulatory agents with the ability to control SLE without subsequent predisposition to infectious complications. Despite the implied risk of developing renal failure due to IVIG, considerable beneficial effects on lupus nephritis are reported. In this review, the clinical and adverse effects, and mechanism of action, with special emphasis on modulation, of idiotypic network is discussed.
