Natalizumab Immune-reconstitution inflammatory syndrome following natalizumab withdrawal: case report
A 35-year-old woman developed immune-reconstitution inflammatory syndrome (IRIS) following natalizumab withdrawal. The woman had been diagnosed with relapsing-remitting multiple sclerosis at the age of 19 years. Despite various unspecified disease-modifying therapies, her disease remained active. She subsequently started receiving natalizumab [dosage and route not stated]. However, 1 year later, she was brought to the emergency department with altered level of consciousness over 24h. She was hospitalised. Anamnesis revealed that 2 months prior to her admission, she had stopped natalizumab therapy by herself. MRI findings revealed about a hundred white matter ovoid-lesions with open-ring enhancement, suggestive of IRIS. The woman was treated with intensive steroids and made a complete recovery after 1 month. Thereafter, she was discharged; her symptoms were attributed to IRIS secondary to natalizumab withdrawal.
