Abstract
We reported an infant case of Guillain- Barré syndrome treated with high-dose gammaglobulin. Gammaglobulin was given at a dose of 1 g/kg/day for 2 cosecutive days. Dyspnea disappeared six hours after the start of the infusion. The patient was able to sit 3 days and walk alone 25 days after the end of therapy. Circulating immune complexes were 48μg/ml before the therapy, 95μg/ml and 39μg/ml 10 days and 37 days, respectively, after the therapy.
