[A case of Guillain-Barré syndrome treated with plasma exchange and intravenous high-dose immune globulin].

We describe a 69-year-old female with Guillain-Barré syndrome (GBS) whose paresthesia and weakness improved after plasma exchange (PE) and intravenous high-dose immune globulin (i.v.I.G.). She felt a paresthesia in her right arm, and 7 days later she noticed right arm weakness followed by gait disturbance within 2 days. She received a series of 6 PEs, but paresthesia and weakness did not improve. Following the last PE trial of this series, she was treated by i.v.I.G. (0.4 g/kg) for 5 days. After i.v.I.G., paresthesia and weakness improved in a few days. After 2nd series of 6 PEs, she was able to walk. In this clinical course, the treatment of i.v.I.G. after PE seemed to be effective. This case raises the possibility that i.v.I.G. might be the treatment in GBS patients with insufficient effect of PE.
