PURPOSE: To evaluate sleep quality using polysomnographic parameters and validated questionnaires and to analize its relationship with asthma control.
METHODS: We performed full polysomnography in 30 selected patients with asthma. We gathered data on their sleep quality through the Pittsburgh sleep quality index (PSQI), the Epworth test and the Insomnia Severity Index (ISI), and we collected data on asthma control (ACT), health resource utilization in the previous year, pulmonary function, and treatment. The Hospital Anxiety and Depression (HAD) test, the Nijmegen questionnaire to detect hyperventilation, and the Sidney Asthma Quality of Life Questionnaire (AQLQ Sidney) were also handed out. We divided patients into partially and uncontrolled if the ACT score was < 20, and into well controlled if the ACT≥ 20. Patients with ISI ≥15 were classified as clinical insomnia, and if they had a PSQI score ≥ 5, as poor sleep quality.
RESULTS: The mean ACT was 19,1 and the mean FEV1 75, 8%. In patients with ACT< 20 the sleep latency was higher with no significant difference (34 vs.22, p = 0.32), they had the worse sleep quality according to the PSQI (9,92 vs.4,75, p = 0.014) and the worse ISI score (11,69 vs. 4,55, p = 0.011). Patients with clinical insomnia had worse ACT score (19,7 vs. 13,8, p=0.03), worse overall AQLQ (1,9 vs. 5,9, p = 0.001), more hyperventilation (Nijmegen 12,7 vs. 29,5, p = 0.012), more anxiety (HDA 6 vs. 16, p = 0.001), more depression (HDA 3,26 vs. 11,25, p = 0.001), and more exacerbations (0,84 vs. 2,2, p=0.088).
CONCLUSIONS: There is probably a bidirectional relation between asthma control and poor quality of sleep. We found poor correlation between polysomnographic parameters, sleep quality questionnaires and characteristics of asthma.
CLINICAL IMPLICATIONS: Assessing sleep disturbance in patients with asthma and its effect on health-related quality of life will help us optimize its treatment and to achieve a better control.
