title: [Prognostic factors in Guillain-Barré syndrome].
abstract: The prognosis of Guillain-Barré syndrome (GBS) is not as good as might be expected. Among GBS patients, 30% do not respond to intravenous immunoglobulin therapy (IVIg) and 10% may worsen after initial treatment (treatment-related fluctuation). Recent prospective trials show that 16% of GBS patients are unable to walk independently a year after onset of the disease. The prognosis of GBS is influenced by clinical, electrophysiological and biological factors, of which the clinical factors are most important. The Erasmus GBS Respiratory Insufficiency Score (EGRIS) and the modified EGOS (Erasmus GBS Outcome Score) are very useful for prediction of mechanical ventilation or aided walking. A small increase in serum IgG (delta IgG) two weeks after IVIg treatment is useful as a biological prognostic marker that is significantly associated with slow recovery and aided walking at 6 months. Use of these factors makes it possible to predict the prognosis of GBS patients, and to identify patients with a poor prognosis in the early phase of the disease and provide these patients with intensive treatment. An accurate prediction of the level of disability is important for improvement of the prognosis of GBS.
