We 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. ⋯ 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.

Carbamoyl phosphate synthetase I deficiency (CPSID) is a rare metabolic disorder affecting the first enzymatic step of urea cycle. We report clinical manifestations of a female case of late-onset CPSID in Japan. An 18-year-old girl was admitted to emergency room due to acute comatose state. ⋯ Genomic DNA analysis showed that she was heterozygous in V1149G mutation. The mutation allele was derived from her father. The causative factor for absence or very low level of maternal CPSI mRNA will require further analysis.
