Some centers will opt for a second course of the initial treatment. There is an ongoing trial of a second course of IVIg in patients with severe GBS.Methods: We retrospectively reviewed 4 patients with severe GBS who received high-dose IVIg. One patient inadvertently received a high dose of IVIg for Miller Fisher syndrome. All patients received a total of at least 2 courses of the standard dose of IVIg (total >4 g/kg). We review their clinical course and side effects.Results: All patients with non-O blood types developed clinically significant hemolytic anemia requiring blood transfusion.Conclusion: Hemolytic anemia may limit doses of IVIg for treatment of severe GBS in patients with non-O blood types.GBS=Guillain-Barré syndrome; HA=hemolytic anemia; IVIg=IV immunoglobulin; MFS=Miller Fisher syndrome
