Treatment of chronic inflammatory demyelinating polyneuropathy

The management of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is the main topic of this review. A few comments will also be made about treatment of the demyelinating form of paraproteinaemic demyelinating polyneuropathy (PDN) and of multifocal motor neuropathy (MMN). The review briefly describes the main characteristics of these neuropathies, and examines case series and trials which evaluated the principal therapeutic strategies for CIDP, PDN and MMN, such as intravenous immunoglobulin (IVIg) therapy, steroid treatment, plasma exchange and immunosuppressor administration. Controlled trials demonstrated that IVIg, steroid treatment and plasma exchange are effective in CIDP. For PDN the therapeutic strategies are the same as for idiopathic CIDP, but usually the clinical response is poorer. For MMN, IVIg therapy is definitely the first choice treatment.
