Abstract INTRODUCTION: The treatment of prolonged, severe relapses in multiple sclerosis (MS) patients who respond poorly to high-dose intravenous corticosteroids is not yet established. Plasma immunoadsortion (IA) removes immunoglobulins (IgG), immune complexes, and complement from plasma. It may bear some advantages compared to plasmapheresis, a nonselective procedure that requires substitution of patient plasma by colloids solutions or plasma, which may carry a potential risk for viral infections. PATIENTS AND METHODS: Three relapsing-remitting MS patients with a malignant course received IA. All they were experiencing a prolonged relapse unresponsive to high-dose intravenous corticosteroids, causing a locked-in state in two of the patients and severe pseudobulbar impairment in the third one. Five to six IA consecutive sessions were administered along a 7-10 days course. RESULTS: IA was followed by a prompt and unequivocal clinical response in all three patients, which paralleled a decrease in IgG, fibrinogen, and C3 complement serum levels. IA administration was followed by immunosuppressor therapy, either with cyclophosphamide and intravenous ACTH (2 cases) or mitoxantrone (1 case). Improvement has been sustained along a mean follow-up of 7.6 years (range: 7-8.5 years), only one of the patients suffering two mild clinical relapses. CONCLUSION: We believe that IA may be useful, either as a coadyuvant or alternative treatment in severe relapses in MS patients that do not respond to high-dose intravenous corticosteroid therapy.
