Résumé
Determinants of quality of life (QoL) in demyelinating disorders have been investigated predominantly for multiple sclerosis, especially with regard to "soft clinical signs" such as psychiatric distress. In this exploratory study, we aimed to identify common determinants of QoL for both central and peripheral demyelination in the understudied disease entities of neuromyelitis optica spectrum disorder (NMOSD) and chronic autoimmune demyelinating polyneuropathy (CADP). 20 NMOSD and 16 CADP patients were evaluated for physical disability (EDSS and INCAT ODSS), cognitive dysfunction (neuropsychological test battery), psychiatric distress (SCL-90-R), depression (BDI), fatigue (FSMC) and quality of life (EQ-5D-3 L). A linear regression with QoL as a dependent variable and clinical parameters and demographic covariates as independent variables was computed. Additionally, a multivariate analysis of variance was computed to investigate whether NMOSD and CADP differed with regard to QoL and clinical parameters. Physical disability and psychiatric distress affected QoL in both NMOSD and CADP with a stronger effect for psychiatric distress in comparison to physical disability, as indicated by the higher standardized beta coefficient for psychiatric distress (b = -0.540; p = 0.002 vs. b = -0.614; p = 0.028). NMOSD reported higher subjective well-being than CADP patients (F = 6.845, p = 0.015) while having similar physical disability, cognitive dysfunction, psychiatric distress, depression and fatigue and after having accounted for the influence of age, gender, education and disease duration. Our findings suggest that physical disability and psychiatric distress above all clinical factors affect QoL in patients with NMOSD and CADP. Addressing adequately this aspect in demyelinating diseases would contribute to a better QoL in these patients. Furthermore, higher subjective well-being scores for NMOSD than CADP might be attributable to the distinct immunomodulatory therapy regimens and course (relapse-driven vs. chronic) of the two diseases.

BACKGROUND
BACKGROUND
Determinants of quality of life (QoL) in demyelinating disorders have been investigated predominantly for multiple sclerosis, especially with regard to "soft clinical signs" such as psychiatric distress. In this exploratory study, we aimed to identify common determinants of QoL for both central and peripheral demyelination in the understudied disease entities of neuromyelitis optica spectrum disorder (NMOSD) and chronic autoimmune demyelinating polyneuropathy (CADP).
METHODS
METHODS
20 NMOSD and 16 CADP patients were evaluated for physical disability (EDSS and INCAT ODSS), cognitive dysfunction (neuropsychological test battery), psychiatric distress (SCL-90-R), depression (BDI), fatigue (FSMC) and quality of life (EQ-5D-3 L). A linear regression with QoL as a dependent variable and clinical parameters and demographic covariates as independent variables was computed. Additionally, a multivariate analysis of variance was computed to investigate whether NMOSD and CADP differed with regard to QoL and clinical parameters.

RESULTS
Physical disability and psychiatric distress affected QoL in both NMOSD and CADP with a stronger effect for psychiatric distress in comparison to physical disability, as indicated by the higher standardized beta coefficient for psychiatric distress (b = -0.540; p = 0.002 vs. b = -0.614; p = 0.028). NMOSD reported higher subjective well-being than CADP patients (F = 6.845, p = 0.015) while having similar physical disability, cognitive dysfunction, psychiatric distress, depression and fatigue and after having accounted for the influence of age, gender, education and disease duration.

CONCLUSIONS
Our findings suggest that physical disability and psychiatric distress above all clinical factors affect QoL in patients with NMOSD and CADP. Addressing adequately this aspect in demyelinating diseases would contribute to a better QoL in these patients. Furthermore, higher subjective well-being scores for NMOSD than CADP might be attributable to the distinct immunomodulatory therapy regimens and course (relapse-driven vs. chronic) of the two diseases.
