AbstractWe experienced a patient of CIDP who was twice complicated with aseptic meningitis following high-dose intravenous gammaglobulin therapy. The patient was a 29-year-old woman who first developed gait disturbance in September 1998. Neurological examination revealed muscle weakness and sensory disturbance in the distal parts of four extremities and decrease of deep tendon reflexes. Cerebrospinal fluid analysis revealed an elevated protein content and a normal cell count. Steroid therapy was effective in early stage, however, this effectiveness had been reduced gradually. She received high-dose intravenous gammaglobulin administrations in September 1999. On the fourth day after start of this therapy, she developed severe headache, nausea and nuchal rigidity without fever. Cerebrospinal fluid analysis revealed an increased cell count of mononuclear predominance and an elevated protein content. As bacterial culture remained negative and viral titers were not elevated, aseptic meningitis was diagnosed. The therapy was stopped, and thereafter her headache continued for 7 days. The muscle weakness and sensory disturbance were remarkably improved, but 9 months later, her symptoms became worse again. She received high-dose gammaglobulin administrations for 2 days in June 2000 and developed aseptic meningitis again. Over again, 9 months later, she received the same medication for only 1 day in March 2001 and she developed mild headache but not meningitis. Aseptic meningitis with CIDP following high-dose gammaglobulin therapy was rare, however, we should pay attention to this therapy in patients with CIDP and may prevent the occurrence of aseptic meningitis by reducing the total dose and shortening the administration periods of gammaglobulin.
