Randomized Controlled Trial Multicenter Study Clinical Trial
Double-blind trial of intravenous methylprednisolone in Guillain-Barré syndrome. Guillain-Barré Syndrome Steroid Trial Group.
Steroids have been beneficial in the treatment of demyelinating diseases with features similar to those of Guillain-Barré syndrome (GBS). However, steroid treatment of GBS has been disappointing; in an earlier trial oral prednisolone was ineffective, although the dose was low and the sample small. We assessed the benefit of a high-dose steroid regimen in a large sample of patients with GBS in a multicentre, randomised, double-blind trial. 242 adult patients were randomised to receive intravenous methylprednisolone (IVMP) 500 mg (124 patients) or a placebo (118) daily for 5 days. ⋯ The 39 patients in the IVMP group who required ventilation did so for a median of 18 days, 9 days fewer than the 44 patients who had a placebo and required ventilation (95% Cl -9.6 to 27.6). Median time to walk unaided was 38 days in the IVMP patients and 50 days in the placebo patients (difference 12 days, (95% Cl -21.3 to 45.3). A short course of high-dose IVMP given early in GBS is ineffective.
