Review: New advances in the treatment of neurological diseases using high dose intravenous immunoglobulins

Abstract

Since the incidental discovery in 1981 that intravenous immunoglobulins (IVIg) are immunomodulatory, they have been investigated in a large number of putative autoimmune diseases. This has led to licensing for idiopathic thrombocytopenic purpura, Kawasaki disease, and in neurological disorders for Guillain-Barré syndrome (GBS). Although not licensed, randomized controlled trials have also shown IVIg efficacy in other neuroimmunological diseases such as multifocal motor neuropathy (MMN), chronic inflammatory demyelinating neuropathy (CIDP), myasthenia gravis, dermatomyositis, and stiff-person syndrome. However, other indications are currently being explored including Alzheimer's disease, postpolio syndrome, and narcolepsy. There are even reports from experimental studies in stroke. The results of recently published clinical trials in both the classical neuroimmunological disorders as well as for new indications are reported and their role in clinical practice is discussed.
