Conversion to Steroid-Responsiveness in a Patient with Motor-Dominant Chronic Inflammatory Demyelinating Polyneuropathy

The subtypes of chronic inflammatory demyelinating polyneuropathy (CIDP) differ in clinical presentation,
electrophysiological and laboratory features, and response to treatment. Steroid therapy is now accepted as a firstor
second-line treatment for CIDP. Patients with steroid-resistant CIDP have been reported, especially among those
with pure-motor or motor-dominant CIDP. The clinical and prognostic features of patients with motor dominant CIDP
are poorly understood. We describe a patient with steroid-unresponsive motor dominant CIDP who subsequently
responded to steroid therapy and review previously reported patients with motor dominant CIDP. Most patients
with motor-dominant CIDP did not respond to steroids, but remarkably improved after treatment with intravenous
immunoglobulins. Our findings suggest that some patients with steroid-unresponsive motor-dominant CIDP can
subsequently become responsive to steroid therapy.
