Sleep disorders, daytime symptoms, and quality of life in veterans with multiple sclerosis: preliminary findings.

ABSTRACT:

Study objectives

Multiple sclerosis (MS) is an autoimmune disease impacting the central nervous system. A hallmark symptom of MS is fatigue, which impairs daytime function and quality of life (QOL). Sleep disorders and disturbances are common in persons with MS and exacerbate fatigue. We evaluated relationships between sleep-disordered breathing (SDB), insomnia symptoms, sleep quality, and daytime functioning in veterans with MS participating in a larger study.

Methods

Twenty-five veterans with clinically diagnosed MS were included (average age = 57 ± 11, 80% male). One had a co-occurring thoracic spinal cord injury. Twenty-four participants completed in-laboratory polysomnography (PSG) to measure apnea-hypopnea index (AHI) and sleep efficiency (PSG-SE). Insomnia Severity Index (ISI) and Pittsburg Sleep Quality Index (PSQI) were used to measure sleep subjectively. The Flinders Fatigue Scale (FFS), Epworth Sleepiness Scale (ESS), PHQ-9 depression scale, and GAD-7 anxiety scale assessed daytime symptoms. The World Health Organization Quality of Life (WHOQOL) was used to assess quality of life. Relationships between sleep (AHI, PSG-SE, ISI, PSQI), daytime symptoms (ESS, FFS, PHQ-9, and GAD-7), and quality of life (WHOQOL) were evaluated with bivariate correlations.

Results

Higher ISI (r = 0.78, 95% CI = [0.54, 0.90], p < .001), higher PSQI (r = 0.51, 95% CI = [0.10, 0.77], p = .017), and lower PSG-SE (r = -0.45, 95% CI = [-0.74, -0.02], p = .041) were associated with worse fatigue (FFS). Higher ISI was also associated with worse WHOQOL (Physical Domain; r = -0.64, 95% CI = [-0.82, -0.32], p = .001). There were no other significant relationships.

Conclusion

In veterans with MS, more severe insomnia and worse sleep quality may be associated with more fatigue and lower quality of life. Recognition and management of insomnia should be considered in future studies of sleep in MS.

Project description:BackgroundSleep disorders and fatigue are common in multiple sclerosis (MS). The underlying causes are not fully understood, and prospective studies are lacking. Therefore, we conducted a prospective, observational cohort study investigating sleep quality, fatigue, quality of life, and comorbidities in patients with MS.MethodsPatients with relapsing-remitting MS or clinically isolated syndrome treated with interferon beta-1b were followed over two years. The primary objective was to investigate correlations between sleep quality (PSQI), fatigue (MFIS), and functional health status (SF-36). Secondary objectives were to investigate correlations of sleep quality and daytime sleepiness (ESS), depression (HADS-D), anxiety (HADS-A), pain (HSAL), and restless legs syndrome (RLS). We applied descriptive statistics, correlation and regression analyses.Results139 patients were enrolled, 128 were available for full analysis. The proportion of poor sleepers (PSQI≥5) was 55.47% at the beginning and 37.70% by the end of the study (106 and 41 evaluable questionnaires, respectively). Poor sleepers performed worse in MFIS, SF-36, ESS, HADS-D, and HADS-A scores. The prevalence of patients with RLS was low (4.5%) and all were poor sleepers. Poor sleep quality was positively correlated with fatigue and low functional health status. These relationships were corroborated by multivariable-adjusted regression analyses. ESS values and poor sleep quality at baseline seem to predict sleep quality at the one-year follow-up. No variable predicted sleep quality at the two-year follow-up.ConclusionsOur results confirm the high prevalence of poor sleep quality among patients with MS and its persistent correlation with fatigue and reduced quality of life over time. They highlight the importance of interventions to improve sleep quality.Trial registrationThe study was registered at clinicaltrials.gov: NCT01766063 (registered December 7, 2012). Registered retrospectively (first patient enrolled December 6, 2012).

Project description:Background and objectivesData from a randomized, controlled study of adenotonsillectomy for obstructive sleep apnea syndrome (OSAS) were used to test the hypothesis that children undergoing surgery had greater quality of life (QoL) and symptom improvement than control subjects. The objectives were to compare changes in validated QoL and symptom measurements among children randomized to undergo adenotonsillectomy or watchful waiting; to determine whether race, weight, or baseline OSAS severity influenced changes in QoL and symptoms; and to evaluate associations between changes in QoL or symptoms and OSAS severity.MethodsChildren aged 5 to 9.9 years with OSAS (N = 453) were randomly assigned to undergo adenotonsillectomy or watchful waiting with supportive care. Polysomnography, the Pediatric Quality of Life inventory, the Sleep-Related Breathing Scale of the Pediatric Sleep Questionnaire, the 18-item Obstructive Sleep Apnea QoL instrument, and the modified Epworth Sleepiness Scale were completed at baseline and 7 months. Changes in the QoL and symptom surveys were compared between arms. Effect modification according to race and obesity and associations between changes in polysomnographic measures and QoL or symptoms were examined.ResultsGreater improvements in most QoL and symptom severity measurements were observed in children randomized to undergo adenotonsillectomy, including the parent-completed Pediatric Quality of Life inventory (effect size [ES]: 0.37), the 18-item Obstructive Sleep Apnea QoL instrument (ES: -0.93), the modified Epworth Sleepiness Scale score (ES: -0.42), and the Sleep-Related Breathing Scale of the Pediatric Sleep Questionnaire (ES: -1.35). Effect modification was not observed by obesity or baseline severity but was noted for race in some symptom measures. Improvements in OSAS severity explained only a small portion of the observed changes.ConclusionsAdenotonsillectomy compared with watchful waiting resulted in significantly more improvements in parent-rated generic and OSAS-specific QoL measures and OSAS symptoms.
