Abstract

Objective: Achieving long-term remission after a limited more intense treatment period would prevent prolonged use of corticosteroids or IV immunoglobulin (IVIg) in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). In this prospective cohort study we present long-term follow-up data on patients included in a multicenter randomized controlled trial comparing 6 monthly pulses of dexamethasone with 8 months of daily prednisolone. Methods: Treatment effect was assessed with the Inflammatory Neuropathy Cause and Treatment disability scale and the Rivermead Mobility Index and was categorized using the CIDP Disease Activity Status (CDAS) scale. Results: By March 2011, 39 out of 40 patients were included with a median follow-up of 4.5 years. Cure (>5 years off treatment) or remission according to the CDAS criteria after 1 or 2 courses of pulsed dexamethasone or daily prednisolone was achieved in 10 out of 39 patients (26%). Half of the patients who were in remission after initial treatment experienced a relapse (median treatment-free interval: 17.5 months for dexamethasone, 11 months for prednisolone). Alternative diagnosis was made in Conclusions: Cure or long-term remission can be achieved in about one-quarter of patients with CIDP after 1 or 2 courses of pulsed dexamethasone or 8-month daily prednisolone. In treatment-nonresponsive patients, the diagnosis CIDP should be reconsidered. Classification of Evidence: This study provides Class IV evidence that pulsed dexamethasone or 8-month daily prednisolone can lead to long-term remission in CIDP. Neurology (R) 2012;78:1079-1084
