Intravenous immunoglobulin for chronic inflammatory demyelinating polyradiculoneuropathy.

Chronic inflammatory demyelinating polyradiculoneuropathy is an immune mediated disorder characterised by progressive or relapsing symmetrical motor or sensory symptoms and signs in more than one limb, developing over at least two months. It may cause prolonged periods of disability and even death. Several uncontrolled studies have suggested a beneficial effect of intravenous immunoglobulin.
