[Randomized controlled trial of high-dose peroral methylprednisolone in attacks of multiple sclerosis].

The efficacy of glucocorticoid treatment in multiple sclerosis (MS) is uncertain. We assessed the effect of oral high-dose methylprednisolone in attacks of MS. Twenty-five patients with an attack of MS with a duration of less than four weeks were randomized to placebo, 26 patients received oral methylprednisolone (500 mg once daily for five days with a 10 days tapering period). Scripps Neurological rating scale scores differed significantly in methylprednisolone and placebo-treated patients the first three weeks (p = 0.005) and after eight weeks (p = 0.0007). Subjective symptom assessment on a visual analogue scale the first three weeks (p = 0.02) and the answers to an efficacy questionnaire administered after eight weeks (p = 0.05) also favoured a beneficial effect of methylprednisolone treatment. The risk of a new attack of MS was not influenced by the treatment at short-term follow up. No serious adverse events were seen. Oral high-dose methylprednisolone is recommended for treatment of attacks of MS.
