Effects of IV methylprednisolone on brain atrophy in relapsing-remitting MS.
Abstract
BACKGROUND: IV methylprednisolone (IVMP) has been used to treat relapses in patients with relapsing-remitting (RR) MS, but its effect on disease progression is not known. Furthermore, there are no data on the impact of IVMP on T1 black holes or whole-brain atrophy.
OBJECTIVE: To determine the effect of IVMP on MRI measures of the destructive pathology in patients with RR-MS and secondarily to determine the effect of IVMP on disability progression in patients with RR-MS.
METHODS: The authors conducted a randomized, controlled, single-blind, phase II clinical trial of IVMP in patients with RR-MS. Eighty-eight patients with RR-MS with baseline Expanded Disability Status Scale (EDSS) scores of < or =5.5 were randomly assigned to regular pulses of IVMP (1 g/day for 5 days with an oral prednisone taper) or IVMP at the same dose schedule only for relapses (IVMP for relapses) and followed without other disease-modifying drug therapy for 5 years. Pulsed IVMP was given every 4 months for 3 years and then every 6 months for the subsequent 2 years. Patients had quantitative cranial MRI scans at study entry and after 5 years and standardized clinical assessments every 4 to 6 months.
RESULTS: Eighty-one of 88 patients completed the trial as planned, and treatment was well tolerated. Baseline demographic, clinical, and MRI measures were well matched in the two study arms. Patients on the pulsed IVMP arm received more MP than patients on the control arm of the study (p < 0.0001). Mean…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 88 participants or records.
