BACKGROUND: Multiple system atrophy (MSA) has considerable effect on
health-related quality of life (Hr-QoL). The aim of this study was to
prospectively evaluate Hr-QoL by using the MSA health-related Quality of Life
(MSA-QoL) scale.
METHODS: Evaluation of 100 patients at baseline and after a mean follow-up of
11.5 months was performed. Assessment was made of potential associations with
established markers of disease progression. Calculation was performed of
sample-size estimates for various effect sizes.
RESULTS: MSA-QoL scale scores were less responsive to change than Unified MSA
Rating Scale (UMSARS) scores. Responsiveness was largely improved and reasonable
sample-size estimates were obtained when limiting the analysis to items with
significant change over time.
CONCLUSIONS: The UMSARS remains the « gold standard » for
disease-modifying/neuroprotection trials. An MSA-QoL Change Scale, based on the
most responsive items, may become a valuable tool.
