title: Severe hyponatremia as the initial sign preceding guillain-barré syndrome, an acute inflammatory demyelinating polyneuropathy: a case report.
abstract: Guillain-Barré syndrome is an immune-mediated polyneuropathy that frequently presents with progressive muscle weakness. Hyponatremia has recently been described as a feature of this condition, generally appearing over the course of the illness and following the diagnosis of this demyelinating process. We report a case of Guillain-Barré syndrome presenting with severe hyponatremia that is further exacerbated by intravenous immune globulin therapy. Awareness should be raised for consideration of both Guillain-Barré syndrome and its treatment with intravenous immune globulin therapy as the cause of hyponatremia.
