    Autologous hematopoietic stem cell transplantation improves fatigue in multiple sclerosis.

    Bose G, Atkins H, Bowman M, Freedman M.

    Abstract

    BACKGROUND:
    Fatigue is a common problem in multiple sclerosis (MS) affecting as many as 90% of patients. The Fatigue Impact Scale (FIS) is a validated measure of fatigue in MS patients. The cause of fatigue in MS is likely multifactorial, with some evidence that ongoing central nervous system (CNS) inflammation is a contributing factor. Immunoablation and autologous hematopoietic stem cell transplantation (aHSCT) have been shown to halt ongoing CNS inflammation.

    OBJECTIVE:
    To investigate whether halting all ongoing inflammation with aHSCT impacts FIS scores in patients with severe MS.

    METHODS:
    In the Canadian aHSCT study ( ClinicalTrials.gov , NCT01099930), 23 patients underwent aHSCT and had FIS prospectively collected every 6 months for 36 months of follow-up. Change in FIS was analysed by repeated-measures analysis of variance (RMANOVA) with multiple linear regression to determine independent predictors.

    RESULTS:
    The median FIS score decreased 36%, from 36 to 23 ( p = 0.001), and four patients had 100% reduction. Improvement in FIS correlated with lower age and Expanded Disability Status Scale at baseline, as well as increased independence as evidenced by a return to gainful employment and even driving.

    CONCLUSION:
    Patients had significantly less fatigue on average after aHSCT. This may serve to better understand the contribution of ongoing CNS inflammation to fatigue peculiar to MS.
