Guillain-Barre syndrome (GBS) is the most common muse of acute generalized paralysis. Although the muse and pathogenesis of GBS remain unknown, there is increasing evidence to suggest that this syndrome has an immunological basis. Two children suffering from GBS were treated with high-dose intravenous immune globulin (IVIG) (1 g/kg/day over two consecutive days). Both children showed marked clinical improvement within 48 hours of the onset of treatment. It is suggested, on the basis of recent case reports, that immunoglobulins may have an important role in the treatment of Guillain-Barre Syndrome.
