ABSTRACT

OBJECTIVE/BACKGROUND: Evaluate the impact of excessive daytime sleepiness (EDS) severity on burden of illness among adults with obstructive sleep apnoea (OSA) in European Union 5 (EU5) countries (France, Germany, Italy, Spain, United Kingdom). PATIENTS/METHODS: This retrospective observational study used data from the 2017 EU5 National Health and Wellness Survey, a self-administered, internet-based, non-screening survey. Respondents who self-reported both having experienced OSA in the last 12 months and having had their OSA diagnosed by a physician were considered to have OSA. Respondents completed the Epworth Sleepiness Scale (ESS) and were consequently categorised into 4 groups: OSA-with-EDS (ESS >10) subdivided by EDS severity (mild [ESS = 11-12], moderate [ESS = 13-15], severe [ESS = 16-24]), and OSA-without-EDS (ESS ≤10). Bivariate and multivariable analyses examined group differences in health-related quality of life (HRQoL), work productivity and activity impairment, and health care utilisation. RESULTS: The analysis included 2008 respondents with OSA: n = 661 (32.9%) with EDS (29.5% mild, 34.5% moderate, 36.0% severe) and n = 1347 without EDS. Compared with the OSA-without-EDS group, the OSA-with-EDS subgroups generally had higher rates of obesity, depression, and other reported comorbidities. Greater severity of EDS was associated with worse self-reported HRQoL (all domains, P < 0.001) and work productivity and activity impairment (absenteeism, P = 0.031; presenteeism, overall work impairment, and non-work activity impairment, P < 0.001), as well as increased numbers of health care provider visits (P < 0.001). CONCLUSIONS: Compared to patients with OSA but without EDS, those with EDS had substantially higher socioeconomic and humanistic burden of disease, which was more profound among those reporting greater EDS.

ABSTRACT

Physical functioning is improved after liver transplantation but studies comparing liver transplant recipients with normal healthy people are lacking. How liver (and other organ) transplant recipients tolerate strenuous physical activities is unknown. There are no data on the tolerance of transplant patients at high altitude. Six liver transplant subjects were selected to participate in a trek up Mount Kilimanjaro 5895 m, Tanzania. Physical performance and susceptibility to acute mountain sickness were prospectively compared with fifteen control subjects with similar profiles and matched for age and body mass index. The Borg-scale (a rating of perceived exertion) and cardiopulmonary parameters at rest were prospectively compared with six control subjects also matched for gender and VO2max. Immunosuppression in transplant subjects was based on tacrolimus. No difference was seen in physical performance, Borg-scales and acute mountain sickness scores between transplant and control subjects. Eight-three percent of transplant subjects and 84.6% of control subjects reached the summit (p=0.7). Oxygen saturation decreased whereas arterial blood pressure and heart rate increased with altitude in both groups. The only difference was the development of arterial hypertension in transplant subjects at 3950 m (p=0.036). Selected and well-prepared liver transplant recipients can perform strenuous physical activities and tolerate exposure to high altitude similar to normal healthy people.
