Treatment with rituximab in patients with polyneuropathy with anti-MAG antibodies.
Résumé
We report on a series of six patients diagnosed as anti-MAG polyneuropathy treated with rituximab. Nine months after the infusion of rituximab, sensory deficiency considered through the INCAT sensory score was improved in 5 patients and functional disability quantified by the overall neuropathy limitation scale was improved in 3 patients. Titers of anti-MAG antibodies and of monoclonal IgM gammapathy decreased respectively by 43% and 31%. No serious adverse event was observed. We did not find any predictive factors statistically related with the response to treatment.
