Recently, ganglioside complexes (GSCs) such as GD1a/GD1b, GD1a/GM1, GD1b/GT1b, GM1/GT1b, GQ1b/GM1 and GQ1b/GD1a have been shown as target antigens for serum antibodies in patients with Guillain–Barré syndrome (GBS)1 and Miller Fisher syndrome (MFS).2 Gangliosides may interact with each other to form a novel epitope, which serves as a target antigen for serum antibodies.1 In paticular, anti-GD1a/GD1b IgG is reported to be associated with severe GBS and requirement of mechanical ventilation.1 However, there has been no previous case report describing GBS with anti-GSC antibodies in detail. In this report, we present a patient with GBS having anti-GD1a/GD1b antibody and investigated the clinical feature.
