Oral versus Intravenous Steroids for Treatment of Relapses in Multiple Sclerosis

  • Review
  • Intervention




Multiple Sclerosis (MS), a chronic inflammatory and neurodegenerative disease of the central nervous system (CNS), is characterized by recurrent relapses of CNS inflammation ranging from mild to severely disabling.  Relapses have long been treated with steroids to reduce inflammation and hasten recovery.  However, the commonly used intravenous methylprednisolone requires repeated infusions with the added costs of homecare or hospitalization, and may interfere with daily responsibilities. Oral steroids have been used in place of intravenous steroids, with lower direct and indirect costs.


The primary objective was to compare efficacy of oral versus intravenous steroids for MS relapses <= 6 weeks. Secondary comparisons included subsequent relapse rate, disability, ambulation, hospitalization, immunological markers, radiological markers, and quality of life.

Search methods

A literature search was performed using Cochrane MS Group Trials Register (July 2008), Cochrane Central Register of Controlled Trials (CENTRAL) "The Cochrane Library 2008, issue 3, MEDLINE (PubMed) (1966-July 2008), EMBASE (1980-July 2008), abstracts from meetings of the American Academy of Neurology (2002-2008), the European Federation of Neurological Sciences (2002-2008), the European Committee for Treatment and Research in Multiple Sclerosis and American Committee for Treatment and Research in Multiple Sclerosis (2002-2008)  handsearching.  No language restrictions were applied.

Selection criteria

Randomized or quasi-randomized trials comparing oral and intravenous steroids for acute relapses (<=30 days) in clinically definite MS patients over age 16 were eligible.

Data collection and analysis

Methodological was assessed using trial publications and personal communication.  Elevant data was extracted, and effect size was reported as mean difference (MD),weighted mean difference (WMD), odds ratio (OR) and absolute risk difference (ARD).

Main results

Eligible studies (167 patients) were identified. Only one outcome, the proportion of patients with EDSS improvement at 4 weeks, was common to three trials. Otherwise outcomes were too heterogeneous to pool. Only one trial employed an equivalence design, but all reported no statistically significant difference in outcomes between groups. Namely, there was no significant difference in the degree of recovery 4 weeks following treatment. No difference was found in subsequent relapse rate, disability, hospitalization, ambulation, bioavailability, or in magnetic resonance imaging (MRI). Due to methodological limitations, heterogeneous treatment regimens and limited data, formal conclusions about equivalence of oral and intravenous steroidscannot be made.  Oral Megadose Corticosteroid Therapy of Acute Exacerbations of Multiple Sclerosis (OMEGA) trial, designed to address such limitations, is currently underway.

Authors' conclusions

The trials reviewed support the hypothesis that no significant differences in clinical, radiological or pharmacological outcomes oral and intravenous steroids for MS relapses exist. However, with the small number of patients and methodological limitations, conclusions of equivalence are premature.

總共找到了四個試驗,合計167個病人。其中三篇試驗有得到相同的結果的只有病人在四周之後擴展殘疾狀態的評分有進步。其他的結果差異性大無法彙整。其中一個試驗選用了等價設計,但所有的結果都告訴我們不同組別間沒有統計上有意義的差異。也就是說,不同的治療方式四周之後恢復的程度差不多。包括之後的復發率,殘障程度,住院天數,行動能力,生物利用率,核磁共振的發現都沒有差別。由於方法學上的差異,不同試驗各異的治療內涵和有限的樣本數,還無法得到最後的結論,口服和針劑的類固醇治療是否相等。目前正在進行的研究,Acute Exacerbations of Multiple Sclerosis(OMEGA) trial,未來希望能夠打破這個困境,得到最後的結論。

Plain language summary

A comparison of oral and intravenous corticosteroid treatments in persons with MS (multiple sclerosis) shows that there are no major differences in clinical outcomes and both treatments appear to be equally effective and safe

Relapsing-remitting MS is characterised by periods of disability due to inflammation in the central nervous system. These episodes are called relapses. All research has shown that a speed up recovery is obtained by corticosteroids, given most often in intravenous form. If oral steroids worked as well as intravenous ones for relapse events, they would be easier to take and are more affordable.
The objective of this review was to assess if oral and intravenous steroids are equally effective and safe. Among the pertinent literature, only four studies met the inclusion criteria, comprising a total of 167 participants. All the studies found that there were no differences in clinical, pharmacological or radiological outcomes in the patients taking oral or intravenous steroids for relapses.
Nevertheless, some limitations in the studies analysed suggest that a definitive conclusion is premature and more rigorous study designs will better address the question of equivalence.
