title: Long-term immunoglobulin therapy for chronic inflammatory demyelinating polyradiculoneuropathy.
abstract: Immunoglobulins are an effective but expensive treatment for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Although the goal is to improve function, use of functional scales to monitor therapy is not widespread. Limited recent evidence suggests that doses lower than those used traditionally may be as effective. There are no proven correlations of effective dose with weight, disease severity, or duration. The clinical course of CIDP is heterogeneous and includes monophasic forms and complete remissions. Careful monitoring of immunoglobulin use is necessary to avoid overtreatment. Definitive evidence for immunoglobulin superiority over steroids is lacking. Although latest trial evidence favors immunoglobulins over steroids, the latter may result in higher remission rates and longer remission periods. This article addresses the appropriateness of first-line, high-dose immunoglobulin treatment for CIDP and reviews important clinical questions regarding the need for long-term therapy protocols, adequate monitoring, treatment withdrawal, and consideration of corticosteroids as an alternative to immunoglobulin therapy.
