Abstract:
:The association of pathology and neurological deficit with quality of life (QoL) in multiple sclerosis (MS) is not fully understood. In this study, magnetic resonance imaging (MRI) measures of pathology--T1 and T2 lesion volume and ratio; active T2 lesion number; global and regional brain volume and atrophy; magnetization transfer ratio (MTR) for lesions, normal appearing grey and white matter (NAGM, NAWM); and spinal cord cross-sectional area-and measures of neurological disability (expanded disability status scale, EDSS), deficit (MS functional composite, MSFC) and inflammatory activity (relapse rate) were compared with the MS impact scale (MSIS-29), in participants in a trial of lamotrigine in secondary progressive MS. Data were collected from 118 people (85 female:33 male) aged 30-61 years (mean 50.6 years)--median EDSS 6.0 (range 4.0-7.5); mean disease duration 20.1 years (range 3-41)--at baseline and 2 years. Regression analysis was used to identify independently significant cross-sectional and longitudinal correlates of the physical (MSIS-phys) and psychological (MSIS-psych) components of the MSIS-29; longitudinal analysis using the 57 people in the placebo arm. The only independently significant correlate of MSIS-phys was 1/timed walk (TW) (p < 0.0001, R (2) = 0.13; p = 0.047, R (2) = 0.09); cross-sectionally the best model for MSIS-psych was the paced auditory serial addition test (PASAT-3) (p = 0.041) and T1-to-T2 lesion volume ratio (p = 0.009) (R (2) = 0.13); longitudinally it was change in 1/TW (p = 0.007), mean NAWM MTR (p = 0.003) and NAGM peak height (p = 0.048) (R (2) = 0.32). These data show that MRI measures and clinical measures do impact on quality of life, but the association is limited.
