Background: Chronic rhinosinusitis (CRS) is known to have a significant impact on economic productivity. Sleep dysfunction is associated with staggering productivity losses and is highly prevalent in patients with CRS. The effect of sleep dysfunction on productivity in CRS has not been elucidated. The objective of this study was to determine the relationship between sleep dysfunction and lost productivity in patients with CRS. Methods: Eighty-two adult patients with CRS were prospectively enrolled into a cross-sectional cohort study. Patients with obstructive sleep apnea were excluded. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Presenteeism (reduced work efficiency), absenteeism (missed work days), and lost work, household, and overall productivity were analyzed. The primary aim was assessing the correlation between PSQI and productivity. Regression analyses were performed to account for disease severity, pain, and depression. Results: Sleep dysfunction is significantly correlated with overall lost productivity (R2 = 0.397, P <.05). Presenteeism is the most strongly affected by sleep dysfunction (R2 = –0.441, P <.001). Higher PSQI scores were significantly associated with productivity losses, whereas lower scores were not. Sleep remained an independent predictor of productivity when regression analysis accounted for disease severity, depression, and pain. Conclusion: Sleep dysfunction has a significant association with lost productivity in patients with CRS, particularly with worsening PSQI scores. More clearly defining those components of CRS that most impact a patient's daily function will allow clinicians to more optimally manage and counsel patients with CRS. [ABSTRACT FROM AUTHOR]

Background: Chronic rhinosinusitis (CRS) is associated with productivity losses exceeding US$13 billion annually. Although pain is well known to significantly affect patient productivity in other diseases, its economic impact on CRS‐related lost productivity has not been examined. The objective of this study was to determine whether CRS‐related facial pain correlates with lost productivity in patients with CRS. Methods: Seventy patients with CRS were enrolled in a cross‐sectional investigation. Patients with a history of systemic inflammatory disease, ciliary dysfunction, chronic pain syndromes, migraines, and fibromyalgia were excluded. Pain was measured using the Brief Pain Inventory Short Form (BPI‐SF) and the Short‐Form McGill Pain Questionnaire (SF‐MPQ). Presenteeism, absenteeism and lost work, and household and overall productivity were assessed. Regression analysis was performed to assess potential confounders, including depression. Results: Pain as measured with BPI‐SF and SF‐MPQ total scores correlated with all domains of productivity losses. Overall, lost productivity was significantly correlated with pain (R range, 0.354‐0.485; p < 0.001). Presenteeism (reduced work efficiency) had the highest correlation with all of the overall pain scores (R range, −0.366 to −0.515; p < 0.001). Lost household productivity time was the least affected by pain (R range, 0.267‐0.389; p < 0.05). These correlations remained statistically significant after regression analysis, which accounted for depression (p < 0.05). Conclusion: A significant correlation exists between CRS‐related facial pain and productivity losses in patients with CRS that is independent of depression. Facial pain has the strongest correlation with presenteeism, which is the main driver of productivity losses and indirect costs associated with CRS. [ABSTRACT FROM AUTHOR]

Objectives/hypothesis: Nasal obstruction is a cardinal symptom in diagnosing chronic rhinosinusitis (CRS), and decreased sleep quality (SQ) and quality of life (QOL) are commonly reported in CRS. It is, however, unclear what role nasal obstruction severity plays in this decreased SQ and QOL. Using validated instruments, we evaluated the relationship between nasal obstruction severity, SQ, and QOL.Study Design: Prospective case series.Methods: Patients with CRS refractory to standard medical therapy (n = 28) were prospectively enrolled and completed the Nasal Obstruction Symptom Evaluation (NOSE), Pittsburg Sleep Quality Index (PSQI), Rhinosinusitis Disability Index, and the 22-item Sinonasal Outcome Test. CRS disease severity was evaluated with computed tomography and endoscopy. NOSE scores were compared to SQ, QOL, and disease severity measures. Spearman correlations were used to identify significant associations between measures.Results: All patients reported symptomatic nasal obstruction (NOSE score ≥ 30), whereas poor sleep (PSQI ≥ 5) was reported by 82%. The NOSE sleeping subdomain correlated strongly with the PSQI total score, whereas other elements of the NOSE instrument correlated weakly or not at all with this measurement of SQ. Nasal obstruction correlated weakly with disease-specific QOL and had no correlation with the PSQI total.Conclusions: Nasal obstruction appears to have a limited association with CRS-specific QOL and CRS-associated decrease in SQ. Further, the NOSE instrument, because it contains a question about sleep, may have overlap with the PSQI as a measure of SQ. The total NOSE score in CRS patients does not appear to be purely a measure of nasal obstruction.Level Of Evidence: 4 Laryngoscope, 126:1971-1976, 2016. [ABSTRACT FROM AUTHOR]

Key points: EPX activity has been correlated with eCRS diagnosis and baseline disease severity.Herein, EPX activity is shown to correlate with post‐operative antibiotic and steroid use in CRS.EPX activity has potential to act as a prognostic biomarker of CRS disease severity and control.

Background: Local sinonasal inflammation resulting from altered T‐cell immune signaling is a contributor to the pathogenesis of chronic rhinosinusitis (CRS). CRS patients experience negative impacts on quality of life (QOL) and suffer from comorbidities linked to systemic inflammation. However, systemic inflammatory profiling to evaluate the association between systemic inflammation and QOL in CRS has not been performed. Our objectives were to compare local and systemic inflammatory gene expression in patients with CRS to determine if systemic markers of inflammation associate with disease severity and disease‐specific QOL. Methods: A prospective observational study was conducted comparing 16 patients with CRS to 10 controls. Inflammatory gene expression in the anterior ethmoid tissues and peripheral blood of patients was measured using multiplex gene expression analysis and correlated to disease severity (computed tomography and nasal endoscopy) and disease‐specific QOL (22‐item Sino‐Nasal Outcome Test [SNOT‐22] and Rhinosinusitis Disability Index) using linear regression analyses. Results: Patients with CRS showed significant increases in the expression of ctla4 and jak1 in sinonasal tissue and blood (p < 0.05), whereas the gene expression of hla‐dqa1, hla‐dqb1, and dusp4 was significantly decreased in patients with CRS compared to controls (p < 0.05). Soluble and local ctla4 and jak1 showed a significant positive correlation with clinical markers of disease severity and disease‐specific QOL (p < 0.05). Conclusion: Local and systemic gene expression involved in T‐cell immune signaling was found to be significantly altered in the blood and sinonasal tissues of patients with CRS compared to controls and significantly correlated to disease severity and QOL in patients with CRS.
