    Nasal obstruction – impact on insomnia symptoms and sleep-disordered breathing2019Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Background: Nasal obstruction is very common in the general population, but the role of nasal obstruction in sleep quality is not clear. Nasal obstruction is also prevalent in patients with obstructive sleep apnoea (OSA) and may contribute to poor adherence to continuous positive airway pressure (CPAP) treatment.

    Aims: To investigate the impact of subjective nasal obstruction, as a single symptom or as part of chronic rhinosinusitis (CRS), in both objective and subjective sleep quality, in three different population based cohorts. Another aim was to investigate the usefulness of the Sinonasal Outcome Test-22 (SNOT-22) and peak nasal inspiratory flow (PNIF) in the treatment of OSA patients.

    Methods and results: In paper I (the SHE-study), a community-based sample of 400 women were investigated with polysomnography and questions on sleep quality, daytime- and nasal symptoms. Women with nasal obstruction at night (n=30) had significantly higher prevalence of several night time symptoms and excessive daytime sleepiness (EDS), but the polysomnography was normal.

    In paper II (the GA2LEN study, n= 26, 647) and paper III (RHINE II and RHINE III studies, n= 5, 145) questionnaires on sleep quality, daytime- and nasal symptoms were used, and CRS was defined according to the epidemiological diagnostic criteria of the European Position Paper of Rhinosinusitis and Nasal Polyps (EPOS). In paper II, sleep problems were highly prevalent in CRS, and there was a dose-response relationship between the disease severity of CRS and sleep problems. The addition of persistent allergic rhinitis to CRS further increased the risk of sleep problems.

    In paper III, 2.7% of individuals without nasal symptoms at baseline had developed CRS at follow-up 10 years later. Strong associations between incident CRS and impaired sleep quality and EDS were found. Three insomnia symptoms at baseline increased the risk for CRS at follow-up.

    In paper IV, 197 OSA patients initiating CPAP treatment were investigated before starting CPAP and at the follow-up 3-4 weeks later. SNOT-22 scores were generally high among all OSA patients indicating a large sinonasal disease burden, and improved among those with CPAP adherence ≥ 4 hours/night. A low PNIF value increased the risk for poor CPAP adherence.

    Conclusions: Subjective nasal obstruction at night impairs subjective sleep quality in women, but does not affect objective sleep quality. CRS impairs subjective sleep quality, and insomnia symptoms may be a risk factor for CRS. SNOT-22 and PNIF may be useful tools in the treatment of OSA patients.

    Abstract [en]

    The aim of the study was to analyse the impact of self-reported nasal obstruction on sleep quality in women. A community-based sample of 400 women underwent a full night of polysomnography. Airway diseases, allergies and sleep-related symptoms were assessed by questionnaires. Women with subjective nasal obstruction were subdivided into three groups: persistent nasal obstruction (PNO, n = 46), hay fever (n = 88) and nasal obstruction at night (NON, n = 30). Sleep problems and related daytime symptoms were most prevalent among women with NON. After adjusting for age, BMI, smoking and asthma, NON was an independent predictor of 'Difficulties inducing sleep due to nasal obstruction' [adjusted odds ratio (95 % CI): 89.5 (27.0-296.7)], 'Snoring' [4.2 (1.7-10.2)], 'Sweating at night' [2.6 (1.1-6.1)], 'Difficulties maintaining sleep' [2.7 (1.2-6.2)], and 'Waking up hastily gasping for breath' [32.2 (8.7-119.1)]. 'Dry mouth on awakening' [7.7 (3.2-18.4)], 'Waking up unrefreshed' [2.7 (1.2-6.0)], 'Excessive daytime sleepiness' [2.6 (1.1-6.0)], and 'Daytime nasal obstruction' [12.2 (4.8-31.2)] were also associated with NON. Persistent nasal obstruction and hay fever were both associated with some reported sleep problems due to an overlap with NON. When women with NON were excluded, only 'Daytime nasal obstruction' was still significantly associated with PNO, while hay fever was associated with 'Daytime nasal obstruction' and 'Waking up hastily gasping for breath'. There were no significant differences in objectively measured sleep variables between any of the three subgroups and the study cohort. Self-reported nasal obstruction at night in women has a significant effect on several subjective day- and nighttime symptoms, but it does not appear to affect objectively measured sleep quality.

    STUDY OBJECTIVES: To analyse the prevalence of sleep problems in subjects with CRS and to determine whether the disease severity of CRS affects sleep quality.

    METHODS: Questionnaires were sent to a random sample of 45 000 adults in four Swedish cities. Questions on CRS, asthma, allergic rhinitis, co-morbidities, tobacco use, educational level and physical activity were included. CRS was defined according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) epidemiological criteria. The disease severity of CRS was defined by the number of reported CRS symptoms. Sleep quality was assessed using the Basic Nordic Sleep Questionnaire.

    RESULTS: Of the 26 647 subjects, 2249 (8.4%) had CRS. Reported sleep problems were 50-90% more common among subjects with CRS compared with those without or the total population. The prevalence of reported sleep problems increased in conjunction with the severity of CRS. After adjusting for gender, BMI, age, tobacco use, asthma, somatic diseases, physical activity level and educational level, participants with four symptoms of CRS (compared with subjects without CRS symptoms) displayed a higher risk of snoring (adj. OR (95% CI): 3.13 (2.22-4.41)), difficulties inducing sleep (3.98 (2.94-5.40)), difficulties maintaining sleep (3.44 (2.55-4.64)), early morning awakening (4.71 (3.47-6.38)) and excessive daytime sleepiness (4.56 (3.36-6.18)). The addition of persistent allergic rhinitis to CRS further increased the risk of sleep problems.

    CONCLUSIONS: Sleep problems are highly prevalent among subjects with CRS. The disease severity of CRS negatively affects sleep quality.

    Abstract [en]

    Study Objectives: Chronic rhinosinusitis (CRS) is a common inflammatory disease of the nasal cavity and paranasal sinuses. Associations between CRS and poor sleep quality have been reported. This 10-year follow-up study investigates possible associations between incident CRS and sleep quality. Methods: A questionnaire was sent to 16,500 individuals in Sweden, Norway, Denmark, Iceland and Estonia in 2000. It included questions on airway diseases, age, sex, body mass index, smoking habits, comorbidities, education and sleep quality. In 2010, a second questionnaire was sent to the same individuals, with a response rate of 53%. A subgroup of 5,145 individuals without nasal symptoms in 2000 was studied. Multiple logistic regression was performed to examine associations between CRS (defined according to the European position paper on rhinosinusitis and nasal polyps epidemiological criteria) at follow-up and sleep quality, with adjustment for potential confounders. Individuals with the respective sleep problem at baseline were excluded. Results: Over 10 years, 141 (2.7%) of the individuals without nasal symptoms in 2000 had developed CRS. CRS was associated with difficulties inducing sleep (adjusted odds ratio 2.81 [95% CI 1.67-4.70]), difficulties maintaining sleep (2.07 [1.35-3.18]), early morning awakening (3.03 [1.91-4.81]), insomnia (2.21 [1.46-3.35]), excessive daytime sleepiness (2.85 [1.79-4.55]), and snoring (3.31 [2.07-5.31]). Three insomnia symptoms at baseline increased the risk of CRS at follow-up by 5.00 (1.93-12.99). Conclusions: Incident CRS is associated with impaired sleep quality and excessive daytime sleepiness. Insomnia symptoms may be a risk factor for the development of CRS.

    STUDY OBJECTIVES: To analyse the prevalence of sleep problems in subjects with CRS and to determine whether the disease severity of CRS affects sleep quality.

    METHODS: Questionnaires were sent to a random sample of 45 000 adults in four Swedish cities. Questions on CRS, asthma, allergic rhinitis, co-morbidities, tobacco use, educational level and physical activity were included. CRS was defined according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) epidemiological criteria. The disease severity of CRS was defined by the number of reported CRS symptoms. Sleep quality was assessed using the Basic Nordic Sleep Questionnaire.

    RESULTS: Of the 26 647 subjects, 2249 (8.4%) had CRS. Reported sleep problems were 50-90% more common among subjects with CRS compared with those without or the total population. The prevalence of reported sleep problems increased in conjunction with the severity of CRS. After adjusting for gender, BMI, age, tobacco use, asthma, somatic diseases, physical activity level and educational level, participants with four symptoms of CRS (compared with subjects without CRS symptoms) displayed a higher risk of snoring (adj. OR (95% CI): 3.13 (2.22-4.41)), difficulties inducing sleep (3.98 (2.94-5.40)), difficulties maintaining sleep (3.44 (2.55-4.64)), early morning awakening (4.71 (3.47-6.38)) and excessive daytime sleepiness (4.56 (3.36-6.18)). The addition of persistent allergic rhinitis to CRS further increased the risk of sleep problems.

    CONCLUSIONS: Sleep problems are highly prevalent among subjects with CRS. The disease severity of CRS negatively affects sleep quality.

    Abstract [en]

    Purpose:

    Intranasal cooling can be used to initiate therapeutic hypothermia. However, direct measurement of brain temperature is difficult and the intra-cerebral distribution of temperature changes with cooling is unknown. The purpose of this study was to measure the brain temperature of human volunteers subjected to intranasal cooling using non-invasive magnetic resonance (MR) methods.

    Methods:

    Intranasal balloons catheters circulated with saline at 20 °C were applied for 60 min in 10 healthy, unsedated volunteers. Brain temperature changes were measured and mapped using MR spectroscopic imaging (MRSI) and phase-mapping techniques. Heart rate and blood pressure were monitored throughout the experiment. Rectal temperature was measured before and after the cooling. Mini Mental State Examination (MMSE) test and nasal inspection were done before and after the cooling. Questionnaires about the subjects personal experience were filled after the experiment.

    Results:

    Brain temperature decrease measured by MRSI was -1.7 ± 0.8°C and by phase-mapping -1.8 ± 0.9°C at the end of cooling. Spatial distribution of temperature changes was relatively uniform. Rectal temperature decreased by -0.5 ± 0.3°C. The physiological parameters were stable and no shivering was reported. The volunteers remained alert during cooling and no cognitive dysfunctions were apparent at MMSE test. Postcooling nasal examination detected increased nasal secretion in 9 of the 10 volunteers. Volunteer’s acceptance of the method was good.   

    Conclusion:

    Both MR techniques revealed brain temperature reductions after 60 min intranasal cooling with balloons circulated with saline at 20 °C in healthy and unsedated volunteers.
