Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a significant source of disability, and early diagnosis and immunomodulatory therapy administration are critical to minimise disease progression and axonal degeneration. Intravenous immunoglobulin (IVIg) therapy is considered to be a first-line treatment for CIDP. Comparative short- and long-term data of IVIg versus corticosteroids in CIDP patients are limited. Of the five published placebo-controlled studies in CIDP, four reported only on short-term improvements in disability (≤6 weeks). However, the IGIV CIDP Efficacy (ICE) study, the largest randomised, placebo-controlled CIDP study published to date (n=117), reported significant improvements in disability, functional impairment and quality of life with IVIg (Gamunex®) 1g/kg maintenance therapy every three weeks for up to 48 weeks. Furthermore, long-term IVIg administration was safe and well tolerated, particularly given the short duration of the infusions. Data suggest that a long-term scheduled maintenance regimen of IVIg in appropriate patients may provide substantial benefit and reduce the risk of CIDP relapse.
