Resumo: The authors examined antibodies against native vacuolating cytotoxin (VacA) of Helicobacter pylori in CSF from 12 patients with Miller-Fisher syndrome (MFS). The VacA protein was separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blotting analysis was carried out. Eight of 12 MFS patients had a specific immunoglobulin G antibody against VacA in the CSF. There is sequence homology between VacA and some membrane ion transport proteins, raising the possibility that A-VacA-Ab involves the ion channels in the node of Ranvier in some patients with MFS.
