ABSTRACT
Herein, we report a case of alopecia universalis and transient accommodation spasm presented after alemtuzumab administration in a patient previously treated with fingolimod. To the best of our knowledge, this is the first report of accommodation spasm as an acute adverse effect of alemtuzumab. Treatment with alemtuzumab in relapsing-remitting multiple sclerosis has been identified as a risk factor for developing secondary autoimmunity within the follow-up period (peak 18-36 months from the first infusion) such as thyroid disorders. This case highlights the need for postmarketing surveillance and the significance of reporting rare side effects related to alemtuzumab; its high efficacy should be weighted with potentially severe adverse events when making a therapeutic decision. Further studies in larger cohorts are needed to elucidate pathomechanisms of alemtuzumab.
