PG - 984-8 LID - 10.1212/WNL.0000000000000222 [doi] AB - OBJECTIVE: To report 3 patients with multiple sclerosis (MS) who presented with daclizumab-related adverse events (AEs) in multiple organ systems. METHODS: A retrospective chart review was performed of patients with MS who had clinical and histopathologic findings suggestive of daclizumab-induced AEs between 2004 and 2010 at the Johns Hopkins MS Clinic. This study met criteria for exemption from review from the institutional review board. RESULTS: Of 20 total patients with MS who had been treated with daclizumab, 3 patients with clinical and histopathologic findings suggestive of daclizumab-induced AEs were identified. All patients were treated with Zenapax (1 mg/kg monthly IV infusions) outside of a clinical trial setting. Clinical manifestations after a mean treatment duration of 20 months consisted of diffuse rash and alopecia, diffuse lymphadenopathy, and breast nodules. Tissue histopathology demonstrated lymphocytic infiltrates with CD56-expressing cells in 2 patients (lymph node, breast nodule). On daclizumab discontinuation, the rash/alopecia and diffuse lymphadenopathy resolved, while the breast nodules stabilized. CONCLUSIONS: Daclizumab-induced AEs can occur in various organ systems after a relatively prolonged duration of exposure and require clinician awareness. Future studies are needed to better understand the relationship between natural killer cells and daclizumab-related AEs. FAU - Oh, Jiwon AU - Oh J AD - From the Department of Neurology (J.
