Autoimmune thyroid events (ATEs) are common side effects after alemtuzumab (ALZ) therapy in patients with multiple sclerosis (MS). Our purpose was to reach more robust evidence on prevalence and outcome of the spectrum of alemtuzumab-induced autoimmune thyroid events in patients with multiple sclerosis.
A 45-year-old Italian woman, affected by relapsing-remitting multiple sclerosis (RR-MS) starting from 2011, started treatment with alemtuzumab in July 2016. Nine months after the second infusion, she had an immune thrombocytopenic purpura (ITP) with complete recovery after steroid treatment. Three months after the ITP, the patient presented with transient aphasia, cognitive deficits, and focal epilepsy. Serial brain magnetic resonance imaging showed a pattern compatible with encephalitis.
