ABSTRACT

Purpose: Sinonasal symptoms are prevalent in COPD, and knowledge of the relationship between these symptoms and clinical markers of COPD is limited. This study explores the associations between the burden of sinonasal symptoms and clinical markers and thresholds recommended for guiding treatment decisions in the GOLD guidelines. Patients and Methods: Sinonasal symptoms were quantified with the rhinological subscale of the Sino-Nasal-Outcome-Test (SNOT-22) in 93 COPD patients characterized by the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2012 diagnostic criteria for rhinosinusitis without nasal polyps (RSsNP). Associations between a high burden, defined as a SNOT22_rhinological score of ≥11, and the following markers were assessed by adjusted multivariable linear regressions; severity of dyspnea [modified Medical Research Council (mMRC)] and cough [Visual Analogue Scale (VAS)], physical activity [6-minute walking distance (6MWD)], mortality risk (BODE index), and HRQoL [disease-specific COPD Assessment Test (CAT) and St. Georges Respiratory Questionnaire (SGRQ), and physical component summary, Short Form-36 version 2.0 (PCS SF-36v2)]. Odds ratios for the association of a high burden and threshold levels for regular treatment were estimated by adjusted binomial logistic regression models. Results: A high burden was associated with greater severity of dyspnea and cough, lower 6MWD, higher BODE index and poorer HRQoL. The odds ratio of having CAT and SGRQ scores that are above the thresholds recommended for treatment was 5-7-fold greater in the high burden group. Conclusion: A high burden of sinonasal symptoms is positively associated with the clinical markers of symptom severity and mortality risk and is inversely associated with physical activity and HRQoL in COPD. These findings add further support that the UAD concept also applies to COPD. Enquiry about sinonasal symptoms in COPD patients should be incorporated into the clinical routine.

ABSTRACT

PURPOSE: The lack of epidemiological data on the proportion of olfactory dysfunction (OD) using comprehensive olfactory assessment in healthy adults in Scandinavia motivated to the present study which aimed to explore the proportion of OD in voluntary healthy Norwegian adults, assessed by Sniffin' Sticks, and its correlation to self-reported olfactory function. Furthermore, sociodemographic and clinical factors associated with olfactory function were analysed. METHODS: The sample included 405 Norwegian participants, aged 18-78 years, 273 women and 132 men, who underwent olfactory testing with extensive Sniffin' Sticks test, allergy testing, clinical examination with nasal endoscopy and completed a self-administered questionnaire, including self-evaluation of olfactory function on a 100 mm Visual Analogue Scale. RESULTS: We found that 37% had OD, of which 1.2% had anosmia assessed with extensive Sniffin' Sticks test. The proportion of hyposmia and anosmia increased with age. Men and participants with low education had poorer olfactory function scores. Allergy, smoking status, general health and endoscopic findings were not associated with measured olfactory function. We found no correlation between self-reported and measured olfactory function. CONCLUSIONS: This study has identified that a large proportion of our sample of voluntary healthy Norwegian adults have OD, considerably more common in older adults and somewhat more common in men and individuals with low education. The lack of correlation between self-reported and measured olfactory function highlights the importance of using validated tests for a reliable olfactory evaluation.

ABSTRACT

Rhinosinusitis without nasal polyps (RSsNP) is prevalent in COPD. Previous studies on its association with health-related quality of life (HRQoL) have limitations, and RSsNP is currently not recognized as a comorbidity. This study investigates HRQoL in COPD including a focus on RSsNP. Generic HRQoL was assessed with the Short Form-36 (SF-36v2) questionnaire and compared between 90 COPD and 93 control subjects and in subgroups with and without RSsNP. The association between RSsNP and COPD versus not and generic HRQoL was assessed by multivariable linear regression with adjustments for age, education, and body mass index (BMI). Disease-specific HRQoL was assessed by Sinonasal outcome test-22 (SNOT-22), St. Georges Respiratory Questionnaire (SGRQ), and COPD Assessment Test (CAT) and compared between COPD with and without RSsNP, and their association to RSsNP was assessed by multivariable linear regression with adjustments for age, BMI, and FEV1% predicted. RSsNP was associated with poorer disease-specific HRQoL, with higher SNOT-22 total score (14.67 points; 95% CI, 7.06-22.28; P < .001) and psychological subscale score (3.24 points; 95% CI, 0.37-6.11; P = .03), SGRQ symptom score (13.08 points; 95% CI, 2.73-23.4; P = .014), and CAT score (4.41 points; 95% CI, 1.15-7.66; P = .009). Generic HRQoL was poorer in COPD patients than in the control subjects. In addition to COPD, concomitant RSsNP was associated with poorer physical functioning, general health, vitality, and physical component summary. RSsNP in COPD is associated with poorer disease-specific HRQoL that is clinically relevant and, as it is amenable for treatment, should be recognized as a comorbidity of COPD.

ABSTRACT

The validity of the united airway disease concept for rhinosinusitis (RS) and chronic obstructive pulmonary disease (COPD) has been questioned because of methodological limitations in previous studies. In this study we investigated the prevalence of RS without nasal polyps (RSsNP) and the severity of sinonasal symptoms in COPD and a corresponding control group. We also evaluated the diagnostic accuracy of these symptoms for RSsNP in COPD. 90 COPD patients and 93 controls were included in an observational cross-sectional study where globally accepted diagnostic criteria of RS and COPD (EPOS 2012 and GOLD) were incorporated; symptomatic and endoscopic criteria for the diagnosis of RS, and spirometry with reversibility for diagnosis of COPD. RS symptoms were identified by responses to the sinonasal outcome test (SNOT-22), nasal endoscopy identified signs of sinonasal disease and discriminated between RS with and without nasal polyps, and visual analogue scales (VAS) rated the severity of sinonasal symptoms. We found RSsNP in 51% of our COPD patients which is threefold greater than in the control group (p<0.001). Nasal discharge (72%) and nasal obstruction (62%) were the two most frequently reported symptoms in COPD. The diagnostic accuracy for RSsNP is better for the composite VAS for rhinological symptoms than for facial symptoms. We conclude that RSsNP is present in 51% of our COPD patients, which is significantly more prevalent compared to a corresponding control group. These results suggest that COPD is associated with RS.
