Outcome Measures for Chronic Inflammatory Demyelinating Polyneuropathy in Research: Relevance and Applicability to Clinical Practice

Abstract

Outcome measures are recommended in the management of chronic inflammatory demyelinating polyneuropathy (CIDP). Various scales have been proposed in recent years, some now commonly utilized in daily clinical practice. The available evidence base relies itself on randomized controlled trial data obtained over the past 30 years, with several studies using different primary and secondary outcomes. We here review the different outcome measures used in CIDP research in relation to those currently recommended for clinical management. We consider the evidence base for CIDP treatment from the primary and secondary outcomes used in these studies and attempt to assess how this may relate to current clinical practice of routine evaluation of treatment effects and long-term monitoring.
