Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired immune-mediated neuropathy. It presents with a course of progression which may be slow and steady or step-wise or relapsing. Sensory ataxic polyneuropathy may be the only clinical manifestation of this disease. Treatment with interferon beta1a (INF beta1a) has been tried with different results in patients who were refractory to other, more conventional, immunomodulatory therapies. Here we report on a patient who had a relapsing form of pure sensory ataxic CIDP and who failed to respond to intravenous human immunoglobulin. He was put on INF beta1a for 3 years. During this period he suffered no relapses while his condition stabilized.
