Objectives: This trial examined the efficacy of a stress management program in reducing neuroimaging markers of multiple sclerosis (MS) disease activity.
Methods:A total of 121 patients with relapsing forms of MS were randomized to receive stress management therapy for MS (SMT-MS) or a wait-list control condition. SMT-MS provided 16 individual treatment sessions over 24 weeks, followed by a 24-week post-treatment follow-up. The primary outcome was the cumulative number of new gadolinium-enhancing (Gdϩ) brain lesions on MRI at weeks 8, 16, and 24. Secondary outcomes included new or enlarging T2 MRI lesions, brain volume change, clinical exacerbation, and stress.Results: SMT-MS resulted in a reduction in cumulative Gdϩ lesions (p ϭ 0.04) and greater numbers of participants remained free of Gdϩ lesions during the treatment (76.8% vs 54.7%, p ϭ 0.02), compared to participants receiving the control treatment. SMT-MS also resulted in significantly reduced numbers of cumulative new T2 lesions (p ϭ 0.005) and a greater number of participants remaining free of new T2 lesions (69.5% vs 42.7%, p ϭ 0.006). These effects were no longer detectable during the 24-week post-treatment follow-up period.
Conclusions:This trial indicates that SMT-MS may be useful in reducing the development of new MRI brain lesions while patients are in treatment.
Classification of evidence:This study provides Class I evidence that SMT-MS, a manualized stress management therapy program, reduced the number of Gdϩ lesions in patients with MS during a 24-week treatment period. This benefit was not sustained beyond 24 weeks, and there were no clinical benefits.Trial registration: ClinicalTrials.gov, number NCT00147446. Neurology ® 2012;79:412-419 GLOSSARY BIPS ϭ Brief Inventory of Perceived Stress; DMT ϭ disease-modifying therapy; EDSS ϭ Expanded Disability Status Scale; Gd؉ ϭ gadolinium-enhancing; ITT ϭ intent-to-treat; LES ϭ Life Events Scale; MS ϭ multiple sclerosis; NNT ϭ number needed to treat; RCT ϭ randomized controlled clinical trial; SMT-MS ϭ stress management therapy for multiple sclerosis; UCSF ϭ University of California San Francisco.Accumulating evidence suggests an association between stress and disease activity in multiple sclerosis (MS).1 Stressful life events have also been shown to precede new gadolinium-enhancing (Gdϩ) MRI brain lesions, a more objective measure of disease activity, by approximately 4 -8 weeks.2 Several studies have indicated that more adaptive coping moderates the effect of stress on the development of new Gdϩ lesions 3 and is associated with fewer exacerbations. 4 Cognitive behavioral stress management therapies (SMTs) teach coping skills that are aimed at enhancing a patient's ability to prevent stressful events from occurring and improving the capacity to manage their responses to those stressful events that do arise.The primary aim of this multicenter randomized controlled clinical trial (RCT) was to examine the efficacy of a well-validated SMT for MS (SMT-MS) 5 in reducing the occurrence of new Gdϩ les...
