Chronic rhinosinusitis and sleep: a contemporary review

Dupilumab improves sleep quality in chronic rhinosinusitis with nasal polyps

PURPOSE

Chronic rhinosinusitis with nasal polyps (CRSwNP) often alters sleep quality. Dupilumab emerged as an innovative and effective therapy for refractory/recurrent severe CRSwNP. The aim of this observational retrospective study was to evaluate the sleep quality in patients with CRSwNP who underwent treatment with dupilumab.

MATERIALS AND METHODS

Forty-five patients treated with dupilumab for CRSwNP were enrolled. Clinical parameters (age, sex, comorbidities, Nasal Polyp Score - NPS, Asthma Control Test - ACT), nasal cytology, quality of life (Sino Nasal Outcome Test 22 - SNOT-22), sleep quality (Pittsburgh Sleep Quality Index - PSQI, Epworth Sleepiness Scale - ESS), and risk of sleep apnea (STOP-BANG) were recorded before treatment (T0), and after 3 (T1), 6 (T2), and 12 months (T3).

RESULTS

NPS, ACT and SNOT-22 total score improved during treatment (p < 0.05). Meanwhile, all sleep parameters evaluated with SNOT-22, ESS and PSQI improved over time (p < 0.001), expect for PSQI Use of sleeping medications. Indeed, sleep drugs are rarely used before and during the treatment. The global sleep quality was classified as poor in 88.9 % of cases at T0 and decreased to 5.7 % at T3. A high risk of sleep apnea was revealed by the STOP-BANG in 68.9 % of cases at T0 and 2.8 % of patient at T3 (p < 0.001).

CONCLUSIONS

Dupilumab improves the sleep quality and reduce the risk of sleep apnea in patients with severe CRSwNP. Its favorable effect occurs within 3 months and is maintained during the treatment.

Snoring in patients with chronic rhinosinusitis after endoscopic sinus surgery

PURPOSES

In patients with chronic rhinosinusitis (CRS), we assessed quality of life (QOL) of chronic rhinosinusitis (CRS) patients with different self-reported snoring frequencies after endoscopic sinus surgery (ESS), and explored factors associated with pre-ESS snoring and post-ESS snoring reduction.

METHODS

This prospective cohort study was conducted in a tertiary referral center in Chengdu, China. Adult patients with medically recalcitrant CRS receiving initial ESS were engaged. Self-reported snoring was measured at baseline and 3-year follow-up, along with Sino-Nasal Outcome Test-22 and snoring visual analog scale assessment. Mouth breathing (MB), demographics, behavior, comorbidity factors, and objective CRS severity were considered.

RESULTS

In 210 patients who completed this study, 63 (30%) patients reported pre-ESS habitual snoring, and post-operative habitual snoring was observed in 52 (25%) patients. The presence of self-reported snoring was correlated with worse CRS QOL at baseline and 3-year follow-up. Obesity (odds ratio [OR] = 4.30; 95% confidence interval [CI], 1.64-11.28; p < 0.01) and posterior-to-anterior ethmoid sinus ratio greater than one (PE/AE, OR = 0.32; 95% CI, 0.10-0.99; p = 0.05) were associated with pre-ESS snoring in univariable and multivariable analysis. The post-operative reduction of snoring frequency was related with patient age over 65 (OR = 11.55; 95%CI, 1.35-98.79; p = 0.03) and bilateral opacification in the Lund-Mackay system (OR = 8.04; 95%CI, 1.24-51.90; p = 0.03) in multivariable analysis. Pre-operative snoring and MB were associated with increased risk of post-operative snoring (p < 0.01 for each comparison).

CONCLUSIONS

Post-ESS, self-reported snoring was associated with worse CRS QOL. Obesity and PE/AE > 1 were risk factors of pre-operative snoring. Advanced age and bilateral opacification were associated with greater improvement of snoring after ESS.

Effect of Hormone Replacement Therapy on Chronic Rhinosinusitis Management

OBJECTIVES

To investigate whether hormone replacement therapy (HRT) impacts health care resource utilization in the management of chronic rhinosinusitis (CRS) in older women.

METHODS

Using the TriNetX US health record database, women 55 years or older with a diagnosis of CRS were included and followed for 3 years. The cohort was stratified into two groups: women who received HRT at the beginning of the study were compared to women who did not receive HRT. The groups were matched by age, race, ethnicity, history of asthma, and history of nasal polyps. Outcomes included whether the patient underwent endoscopic sinus surgery (ESS) and frequency of antibiotic use. Measures of association, Kaplan-Meier analysis, and cohort descriptive statistics were calculated.

RESULTS

Of the 65,400 women included, the mean age was 66.9 years. 27.0% and 3.6% of patients had a history of asthma or nasal polyps, respectively. Overall, 2.0% of CRS patients underwent ESS, with the HRT group less likely to undergo ESS [OR: 0.28; 95% CI: (0.25-0.32)] compared to patients who did not receive HRT. When stratified by polyp status, HRT patients with nasal polyps had a greater decrease in ESS rates compared to control than HRT patients without nasal polyps. The HRT group had a higher mean number of antibiotic prescriptions compared to the non-HRT group.

CONCLUSION

HRT is associated with decreased utilization of ESS to treat CRS, with a greater effect size for ESS among CRSwNP patients. However, HRT was associated with higher antibiotic utilization.

Nasal polyp syndrome: a patient-centred term for CRSwNP by EUFOREA

Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is a chronic inflammatory disease of the nose and paranasal sinus cavities that significantly affects well-being and social function, particularly in young adults and middle-aged populations. CRSwNP is a common health condition in the Western world, with an estimated prevalence of 3%. Despite worldwide evidence-based treatment guidelines such as the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2020 and the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) chronic rhinosinusitis (CRS) pocket guide, a significant number of patients remain undiagnosed and/or uncontrolled with repeated oral corticosteroids (OCS) treatments and/or (multiple) endoscopic sinus surgeries (ESS).

Prevalence and influencing factors of sleep disorders in patients with CRS: a protocol for systematic review and meta-analysis

BACKGROUND

Chronic rhinosinusitis (CRS) is a common chronic disease that seriously affects patients' quality of life and imposes a heavy physical and mental burden on patients. There is growing evidence that sleep disorders are strongly associated with patients with CRS. However, there is no systematic evidence to clarify the prevalence and influencing factors of sleep disorders in patients with CRS with nasal polyps (NP) (CRSwNP) and CRS without NP (CRSsNP). For this reason, this study will systematically analyse the prevalence of sleep disorders in patients with CRSwNP and CRSsNP and explore the related influencing factors.

METHODS AND ANALYSIS

We will electronically search PubMed, Web of Science, Embase, Cochrane, Ovid, Scopus, the China National Knowledge Infrastructure, the Wanfang database, the China Biomedical Literature Database and the China Scientific Journals Database from the establishment of the database to September 2023 to collect the prevalence of sleep disorders in patients with CRSwNP or CRSsNP and related studies on factors affecting sleep disorders. Two researchers will independently conduct literature screening and data extraction and evaluate the quality of the included studies using the Newcastle-Ottawa Quality Scale and Agency for Healthcare Research and Quality scales. The extracted data will be meta-analysed using Review Manager 5.3 and Stata 14.0 software, and the quality of the evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation. Publication bias will be assessed using the funnel plots, Egger's test and Begg's test.

ETHICS AND DISSEMINATION

This review will not require ethical approval, as we will only use research data from the published documents. Our final findings will be published in a peer-reviewed, open-access journal for dissemination.

The Role of Corticosteroid Nasal Irrigations in the Management of Chronic Rhinosinusitis: A State-of-the-Art Systematic Review

Chronic rhinosinusitis (CRS) is a highly prevalent condition. CRS is usually managed with intranasal corticosteroids, useful both before as well as after endoscopic sinus surgery (ESS). However, the greatest drawback of these low-volume sprays is the inadequate delivery into the paranasal sinuses, even after ESS. Recent studies have shown that high-volume steroid nasal rinse (HSNR) has a significantly better penetration of the paranasal sinuses. The purpose of this state-of-the-art review is to systematically overview the current literature about the role of nasal rinses with steroids in CRS. Four authors examined four databases (Embase, Pubmed, Scielo, Cochrane). This review identified 23 studies answering 5 research questions. It included 1182 participants, 722 cases, and 460 controls. Available evidence suggests a potential positive effect of HSNR, which seems to be higher in CRS with nasal polyps. More well-designed studies are needed in order to obtain solid conclusions. The evidence is solid regarding the safety of this treatment modality in the short and long-term. We expect that this lack of severe negative effects will facilitate the acceptance of this treatment modality and the development of future studies.

Work productivity and activity impairment in patients with chronic rhinosinusitis undergoing endoscopic sinus surgery-A prospective, multi-institutional study

BACKGROUND

Productivity loss and activity limitations due to chronic rhinosinusitis (CRS) are known to contribute to the significant economic and personal burden of disease. The purpose of this study was to assess productivity and activity impairment before and after endoscopic sinus surgery (ESS) for medically refractory CRS.

METHODS

This investigation was a prospective, multi-institutional, observational cohort study. Patients diagnosed with medically refractory CRS completed the Work Productivity and Activity Impairment-Specific Health Problem (WPAI-SHP) questionnaire before surgery and approximately 6 months after the procedure. Factors associated with minimal clinical important differences (MCIDs) for productivity and activity impairment were identified.

RESULTS

A total of 279 study participants were screened for inclusion, of whom 176 (63.1%) with postoperative follow-up were included in the final cohort. Preoperative productivity and activity impairment were observed in 63.2% and 69.8% of the patients, respectively. Among these patients, postoperative improvement equaling at least 1 MCID was reported in both productivity (76.1%) and activity (76.4%) impairments. Multivariate regression identified sphenoidotomy (odds ratio [OR], 4.18; 95% confidence interval [CI], 1.03-17.02) as the only factor associated with increased likelihood of productivity improvement, whereas septoplasty during ESS (OR, 8.45; 95% CI, 2.33-30.68) and migraine (OR, 0.35; 95% CI, 0.12-0.96) were associated with differential odds of activity improvement.

CONCLUSION

CRS is associated with a substantial burden on productivity and activity that significantly improves after treatment with ESS. These data may facilitate improved patient counseling and shared decision-making regarding surgical management for CRS.

Use of low-level laser therapy for patients with chronic rhinosinusitis: a single-blind, sham-controlled clinical trial

Chronic rhinosinusitis (CRS) is one of the most common conditions all over the world. The purpose of this study was to investigate the effects of low-level laser therapy (LLLT) in patients with CRS. Fourteen adult patients with CRS participated in this single-blind, sham-controlled clinical trial (12 male, mean age 40 years). Patients received five successive sessions of sham laser followed by five successive sessions of real laser after 2 days. Ga-Al-As laser of 830 nm in a continuous mode at a power output of 30 mW and energy dose of 1 J was applied on the cheeks and the forehead for the maxillary and frontal sinuses, respectively. Laser was delivered on six points over each sinus, each point for 33 s. Four measurements were taken. The total symptom score (TSS) was calculated as the primary outcome measure. The effects of LLLT on TSS were evaluated by using repeated measure ANOVA. The percentage improvement of real laser and sham laser was compared by Wilcoxon signed ranked test. Cohen's d was used to calculate the effect size. Total symptom score significantly improved after real laser (p = 0.015, Cohen's d = 0.69). The percentage improvement for real laser (34.12 ± 46.43) was significantly better than the sham laser (5.02 ± 37.34, Z =  - 2.23, p = 0.026). No significant improvements were observed after sham laser. This study indicates that five-session active LLLT when compared with sham is effective in the treatment of CRS symptoms.

Financial Hardship Impacts Depression and Anxiety Among U.S. Patients with Sinusitis

BACKGROUND

Mental health conditions are common in the United States, and recent efforts have examined the development of mental health conditions among patients with sinusitis.

OBJECTIVES

The purpose of this study was to investigate the association between depression, anxiety, and financial hardship among patients with sinusitis.

METHODS

Cross-sectional study using the 2018 National Health Interview Survey (NHIS). Data regarding demographics, perceived financial hardship, self-reported depression and anxiety, mental healthcare utilization, and treatment compliance were obtained.

RESULTS

Among patients with sinusitis (N = 28 million adults), 9% reported depression and 24% reported anxiety. Sinusitis patients with depression and anxiety reported an increased severity of financial insecurity (p < 0.001). On multivariable logistic regression, worsening financial insecurity increased the odds of depression and anxiety. Patients reporting the highest financial insecurity severity had the highest odds of depression (OR = 3.88, 95% CI = 3.84-3.93, p < 0.001) and anxiety (OR = 2.09, 95% CI = 2.08-2.10, p < 0.001) among measures of financial stress. Specific financial stressors were independently associated with patient-reported depression and anxiety. Sinusitis patients with increased financial insecurity were more likely to require mental health services and treatment (p < 0.001), but were also more likely to report cost-related treatment noncompliance (p < 0.001) and reduced access to mental healthcare due to costs (p < 0.001).

CONCLUSION

Perceived financial hardship is associated with self-reported depression and anxiety among patients with sinusitis. Sinusitis patients with financial hardship also face challenges in accessing and maintaining mental health services and treatment due to costs. Understanding the burden of financial insecurity on mental health and access to treatment may improve quality of care through the development of screening tools and individualized treatment strategies.

Managing Chronic Rhinosinusitis with Nasal Polyps in the Elderly: Challenges and Solutions

The proportion of the population over 65 years old continues to grow. Chronic rhinosinusitis is common in this population and causes a reduction in quality of life and an increase in health care utilization. Diagnosis of chronic rhinosinusitis with nasal polyps follows the same principles for elderly patients as in the general population, but the elderly population presents some diagnostic challenges worth considering. Presbynasalis, the anatomic and functional changes of the nose and paranasal sinuses associated with aging must be accounted for when caring for these patients. In addition, polypharmacy and other medical issues that can cause similar symptoms must be considered. Medical therapy is generally similar to the general population but with additional concerns given the propensity for geriatric patients to be on multiple medications and to suffer from multiple medical issues. Sinus surgery should be considered following the same indications as in the general population. While some authors have found higher complication rates in endoscopic sinus surgery, others have found higher rates of success. As always, the risks of surgery must be considered with the possible benefits on a patient-to-patient basis.

Economic Evaluation of Dupilumab versus Endoscopic Sinus Surgery for the Treatment of Chronic Rhinosinusitis with Nasal Polyps

BACKGROUND

Dupilumab is a novel monoclonal antibody that recently received FDA approval for the treatment of chronic rhinosinusitis with nasal polyps (CRSwNP). Endoscopic sinus surgery (ESS) has been the mainstay of treatment for patients refractory to initial medical therapy. Data comparing the cost-effectiveness of these treatments is scarce. The objective of this study is to compare the cost-effectiveness of dupilumab and ESS treatment for patients with CRSwNP refractory to medical therapy.

METHODS

A cohort-style Markov decision tree economic evaluation with 10-year time horizon was performed. The two comparative treatment strategies were dupilumab therapy or ESS followed by postoperative maintenance therapy. Patients with response to treatment continued with either maintenance or dupilumab therapy; patients with no response underwent ESS. The primary outcome measure was incremental cost per quality-adjusted life year (QALY) calculated from sino-nasal outcome test (SNOT-22) scores. Sensitivity analyses were performed including discounting scenarios and a probabilistic sensitivity analysis.

RESULTS

The dupilumab strategy cost $195,164 and produced 1.779 QALYs. The ESS strategy cost $20,549 and produced 1.526 QALYs. This implies an incremental cost of $691,691 for dupilumab for every one-unit increase in QALY compared with ESS. Probability sensitivity analysis indicated that ESS was more cost-effective than dupilumab in all iterations.

CONCLUSIONS

While dupilumab and ESS may demonstrate similar clinical effectiveness, ESS remains the most cost-effective treatment option and should remain standard of care for CRSwNP patients refractory to medical therapy. This article is protected by copyright. All rights reserved.

Vascular permeability in chronic rhinosinusitis enhances accumulation and retention of nanoscale pegylated liposomes

Chronic rhinosinusitis (CRS) is a debilitating inflammatory disorder of the sinonasal mucosa that substantially diminishes patient quality of life. Progress surrounding management of this disease has been crippled by a lack of therapeutic innovation. It has been posited that increased vascularity within the diseased sinuses of patients with CRS may allow for improved systemic drug delivery via nanoscale liposomal carriers. Such a system could enhance drug distribution, accumulation, and retention within the sinuses, ultimately leading to improved patient outcomes. PEGylated liposomes loaded with indocyanine green (ICG) were synthesized, characterized and systemically administered in a mouse model of CRS. Accumulation and retention of ICG in sinonasal tissue were evaluated. Compared to healthy controls, CRS mice showed significant sinonasal tissue accumulation and retention of PEGylated liposomal ICG for up to 21 days (P < 0.001). Conversely, free ICG was eliminated from the body after 24 h in both groups.

Sleep-disordered breathing in cystic fibrosis

Sleep-disordered breathing (SBD) is an under recognized comorbidity in the cystic fibrosis (CF) population across the lifespan. Nocturnal hypoxemia, obstructive sleep apnea, and nocturnal hypoventilation are respiratory abnormalities that occur commonly during sleep in patients with lung disease, and have deleterious consequences to the quality of life in people with CF. Effective screening for these abnormalities is needed to allow for timely initiation of treatment, which has been reported to be efficacious. Lack of treatment leads to worsened pulmonary, cardiovascular, and metabolic outcomes in patients. In this review, we give an overview of SBD for the CF clinician, including prevalence, treatment, and suggestions for future research. We strongly encourage the CF community to incorporate evaluation for SBD in CF clinical care so that outcomes for the subset of the CF patients with comorbid SBD improve.

Effect of obstructive sleep apnea on immunity in cases of chronic rhinosinusitis with nasal polyp

Objective

Chronic rhinosinusitis (CRS) with nasal polyp (wNP) is a more severe inflammatory form of CRS that often coexists with obstructive sleep apnea (OSA). However, little is known the relationship between OSA and immunologic profile on patients with CRSwNP. We aimed to investigate the immune profile of patients with CRSwNP according to OSA severity.

Methods

This study included 63 patients with CRSwNP and nine control subjects. Protein levels of inflammatory mediators were determined using multiplex immunoassay. All patients underwent standard polysomnography.

Results

We found that, in patients with eosinophilic CRSwNP (ECRSwNP), IL-6 and CXCL-1 (type 1 immune-related markers) were upregulated in cases of moderate-to-severe OSA. Additionally, IL-4, IL-13, CCL-11, CCL-24 (type 2 immune-related markers), and IL-17A (type 3 immune-related marker) were increased in patients with moderate-to-severe OSA. Though there were no significant differences in type 1, 2, or 3 immune-related markers among patients with non-eosinophilic CRSwNP (NECRSwNP) according to the severity of OSA, TGF--β expression was increased in those with moderate-to-severe OSA. Furthermore, in ECRSwNP with moderate-to-severe OSA, associations were detected between serum markers and some upregulated inflammatory markers.

Conclusion

Our findings revealed that OSA may increase the heterogeneity of immune profiles (types 1, 2, and 3) in patients with ECRSwNP but not in those with NECRSwNP.

[Research progress on quality of life in patients with chronic rhino sinusitis]

With the development of modern medical technology, people not only require the extention of life, but also pay more attention to the quality of life. Chronic rhino-sinusitis is a common disease in Otolaryngology Head and Neck Surgery, and its incidence has increased slightly in recent years. The symptoms seriously disturb patients' daily life and affected patients' quality of life. This review first describes the current status of quality of life for patients with chronic sinusitis, secondly analyzes the factors that affect the quality of life of patients with chronic sinusitis, describes various quality of life scales for chronic rhinosinusitis, and finally conducts a comprehensive evaluation of future research directions.

The effects of intermittent hypoxia on human nasal mucosa

Purpose

Intermittent hypoxia (IH) is characterized by hypoxia-reoxygenation, reported to be a critical risk factor for obstructive sleep apnea (OSA). This experiment aimed to evaluate the direct effects of IH on the human nasal mucosa.

Methods

The direct effects of IH on the human nasal mucosa was evaluated by measuring the ciliary beat frequency (CBF) and expression levels of inflammatory cytokines (granulocyte-macrophage colony-stimulating factor, transforming growth factor-β, interleukin-6, and tumor necrosis factor-α). The normoxia group was exposed to a normoxic condition for 72 h. The IH group was exposed to 288 cycles of IH (1 cycle: hypoxia, 5 min; subsequent normoxia, 10 min) for 72 h. CBF was measured using an automated computer-based video image processing technique. Changes in the expression of cytokines were assessed by real-time reverse transcription-polymerase chain reaction (RT-PCR).

Results

The normoxia group revealed a persistent CBF pattern and a physiological range of inflammatory cytokines. However, the IH group showed a cyclic decrease in CBF and increased expression of inflammatory cytokines. Cytotoxicity assay indicated no difference in the survival rates between the two groups.

Conclusions

IH results in increased expression of inflammatory cytokines that adversely affects the mucociliary transport in the upper airway and, consequently, may result in airway inflammation.

Patient-reported sleep outcomes lack association with mucosal eosinophilia or neutrophilia in patients with chronic rhinosinusitis undergoing functional endoscopic sinus surgery

BACKGROUND

Chronic rhinosinusitis (CRS) is associated with sleep dysfunction, but the underlying pathophysiology is poorly understood. The purpose of this study was to determine if mucosal eosinophilia or neutrophilia were associated with sleep dysfunction severity or altered the improvement in sleep dysfunction following functional endoscopic sinus surgery (FESS).

METHODS

A total of 104 patients with medically refractory CRS with nasal polyposis (CRSwNP) and CRS without nasal polyposis (CRSsNP), completed the Pittsburgh Sleep Quality Index (PSQI) before and after FESS. Anterior ethmoid mucosa was collected during FESS and densest infiltrates of eosinophilia and neutrophilia per high-power field (HPF) were determined by microscopy. Eosinophilic (>10 eosinophils/HPF) and neutrophilic (>4 neutrophils/HPF) CRS were then compared to preoperative and postoperative PSQI measures.

RESULTS

Of 104 study participants, 88 (85%) reported preoperative PSQI scores consistent with "poor sleep," (PSQI total > 5). The cohort overall demonstrated significant improvement in poor sleep (65%; χ² = 12.03; p < 0.001) 16.8 ± 5.0 months after FESS. Regardless of nasal polyposis, neither eosinophilic nor neutrophilic CRS was associated with differences in mean postoperative PSQI improvement. However, in patients with neutrophilic CRSsNP, there was a significant relationship between severity of neutrophilia and improvement in sleep latency (R = -0.798, p = 0.003) and sleep efficacy (R = -0.777, p = 0.005).

CONCLUSION

Chronic inflammation has been hypothesized to play a pathophysiologic role in sleep dysfunction associated with CRS. This study suggests that in patients with medically refractory CRS, evidence of mucosal eosinophilia and neutrophilia lack strong associations with patient-reported sleep dysfunction or improvements in sleep quality after FESS, overall. However, neutrophilia may impact sleep latency and efficacy in patients with CRSsNP.

Rhinitis: The Osteopathic Modular Approach

Historically, osteopathic principles have focused on the appropriate drainage of cranial structures to relieve symptoms of rhinitis, which include nasal congestion, anterior/posterior rhinorrhea, sneezing, and itching. Allergic rhinitis is primarily an aberrant immunologic reaction caused by cytokines secreted from lymphocytes that traverse the lymphatic pathway throughout the body. Several studies have documented that, when manipulated, the lymphatic system enhanced the motion of these lymphocytes to important immune structures in both human and animal models. Additionally, modulation of both sympathetic and parasympathetic outflow has been found either to inhibit or enhance secretion and/or drainage of important allergic sites. Osteopathic approaches to rhinitis play an effective role in the comprehensive management of rhinitis, and techniques based on these approaches are therapeutic options for rhinitis. This article provides an up-to-date literature review about the management of rhinitis using the 5 models of osteopathic medicine: biomechanical, respiratory-circulatory, metabolic, neurologic, and behavioral.

The Nose and Nasal Breathing in Sleep Apnea

Assessment of the nose is critical in evaluating obstructive sleep apnea (OSA) because the nose plays an important role in the physiology of sleep by regulating nasal airway resistance and stimulating ventilation. Nasal obstruction is common in sleep apnea, contributes to OSA, and interferes with tolerance of OSA treatment with continuous positive airway pressure (CPAP) or oral appliances. Medical treatment of nasal obstruction and rhinitis with nasal corticosteroid sprays is associated with improved OSA severity and sleep symptoms. Surgery for nasal obstruction, including septoplasty, turbinate reduction, rhinoplasty, and sinus surgery, improves OSA-related quality-of-life measures and CPAP tolerance.

The Influence of Functional Endoscopic Sinus Surgery on Sleep Related Outcomes in Patients with Chronic Rhinosinusitis

Purpose

Chronic rhinosinusitis (CRS) patients often complain of nasal obstruction, which may cause sleep impairment for them. The goal of this study was to investigate the influence of functional endoscopic sinus surgery (FESS) on sleep related outcomes in CRS patients.

Materials and Methods

CRS patients who received FESS were included in this study. Prior to FESS and 3 months after surgery the patients were asked about the severity of nasal obstruction and completed the 20-item Sinonasal Outcome Test (SNOT-20), along with the Epworth Sleepiness Scale (ESS) questionnaire. Endoscopic examination, acoustic rhinometry, and polysomnography were performed in all patients. They were divided into four groups according to their preoperative apnea hypopnea index (AHI) scores: nonobstructive sleep apnea syndrome (non-OSAS), mild OSAS, moderate OSAS, and severe OSAS.

Results

A total of 96 subjects completed the study. The scores of the sleep domain of the SNOT-20 and ESS decreased in all of the AHI groups, with the exception of the severe OSAS group, after FESS. A reduction in the AHI of less than 5 was achieved in 9 patients (13.2%) after FESS.

Conclusions

Our results showed that FESS improved sleep quality in CRS patients, except those with severe OSAS, and a preoperative lower AHI was the only significant predictor of post-FESS OSAS outcome.

The Association between Health Conditions in World Trade Center Responders and Sleep-Related Quality of Life and Sleep Complaints

Background: World Trade Center (WTC) dust-exposed subjects have multiple comorbidities that affect sleep. These include obstructive sleep apnea (OSA), chronic rhinosinusitis (CRS), gastroesophageal-reflux disorder (GERD) and post-traumatic stress disorder (PTSD). We examined the impact of these conditions to sleep-related outcomes. Methods: Demographics, co-morbidities and symptoms were obtained from 626 WTC (109F/517M), 33⁻87years, BMI = 29.96 ± 5.53 kg/m²) subjects. OSA diagnosis was from a 2-night home sleep test (ARES^TM). Subjective sleep quality, sleep-related quality of life (QOL, Functional Outcomes of Sleep Questionnaire), excessive daytime sleepiness (Epworth Sleepiness Scale), sleep duration and sleep onset and maintenance complaints were assessed. Results: Poor sleep quality and complaints were reported by 19⁻70% of subjects and average sleep duration was 6.4 h. 74.8% of subjects had OSA. OSA diagnosis/severity was not associated with any sleep-related outcomes. Sleep duration was lower in subjects with all conditions (p < 0.05) except OSA. CRS was a significant risk factor for poor sleep-related QOL, sleepiness, sleep quality and insomnia; PTSD for poor sleep-related QOL and insomnia; GERD for poor sleep quality. These associations remained significant after adjustment for, age, BMI, gender, sleep duration and other comorbidities. Conclusions: Sleep complaints are common and related to several health conditions seen in WTC responders. Initial interventions in symptomatic patients with both OSA and comorbid conditions may need to be directed at sleep duration, insomnia or the comorbid condition itself, in combination with intervention for OSA.

Quality of life outcomes of patients with chronic rhinosinusitis after functional endoscopic sinus surgery, prospective cohort study

OBJECTIVES

To compare the outcome of patients with unilateral CRSsNP (U CRSsNP) and bilateral CRSsNP (B CRSsNP) undergoing FESS. Also, we evaluate the impact of SNOT-22 domains to predict their quality of life (QOL) outcomes and compare these factors with those of CRSwNP group, published in previous work.

METHODS

A prospective cohort study was performed in the hospital 20 August,66 patients who were presented between January 2016 and December 2017 were diagnosed with CRS according to guideline recommendations, and were beforehand refractory to initial medical therapy and elected to FESS. The Sino Nasal Outcome Test-22 (SNOT-22) was used to evaluate QOL.

RESULTS

A higher significant improvement was observed between preoperative and postoperative SNOT-22 scores in U CRSsNP group [37.13 ± 9.307 versus 14.11 ± 8.531] and in B CRSsNP group [41.76 ± 6.949 versus 18.57 ± 8.495]. In the U CRSsNP group, patients having a preoperative SNOT-22 score higher than 20 points attained MCID in 88%. For the other group, patients having preoperative SNOT-22 score superior to 40 points achieved MCID in 66%. A multivariate logistic regression model found preoperative predictors that have impact on QOL outcomes.

CONCLUSIONS

Outcomes from this study suggest that patients with U CRSsNP having a preoperative SNOT-22 scores between 10 and 19, and patients with B CRSsNP having a preoperative SNOT-22 scores between 10 and 19 or 20-29 had no chance of achieving an MCID improvement after FESS. Also, preoperative rhinologic symptoms and preoperative psychological dysfunction domains of SNOT-22 are helpful tools to predict improvement after FESS unlike the unilateral character of CRS.

A comparative clinical and radiographic study on patients with chronic facial pain with and without temporomandibular disorder presenting to an otolaryngology clinic

Objective: Facial pain associated with temporomandibular disorder (TMD) is considered a component of Costen's syndrome. However, prior to the current study, no previous clinical and radiographic studies have addressed facial pain in patients with TMD. Methods: The study included 212 patients with chronic facial pain examined in an otolaryngology clinic. These were stratified into 132 patients with TMD and 80 patients without TMD. Clinical and radiographic findings were documented in both groups. Results: Forty-eight patients in the TMD group had normal endoscopic findings and clear CT scans and had their facial pain directly attributable to TMD. Conclusion: In patients presenting with facial pain, where nasal endoscopy reveals no abnormality, TMD should be specifically addressed, especially if CT scans of the paranasal sinuses are clear.

The role of sinus surgery in sleep outcomes

PURPOSE OF REVIEW

Poor sleep is associated with reduced health, increased morbidity, and increased mortality.

RECENT FINDINGS

Chronic rhinosinusitis (CRS) is one of the most prevalent chronic diseases in the United States, affecting up to 16% of the U.S.

POPULATION

It has been linked to poor sleep with up to 75% of patients with CRS reporting reduced sleep. Yet there has been little examining the improvement in sleep following surgical treatment of patients with CRS.

SUMMARY

In this review, we examine the current knowledge on the association between sleep and CRS as well as review the current data examining the role of sinus surgery. After a structured literature search, we conclude that an evolving body of research demonstrates that sleep is compromised in the majority of patients with CRS. Following surgical treatment of CRS, there is a significant improvement in reported sleep quality that is correlated with subsequent improvement in disease-specific quality of life. Furthermore, we acknowledge that additional research characterizing both objective and subjective measures of sleep following surgical treatment is still needed. Additional investigation is required to better elucidate the underlying pathophysiology of the relationship between sleep dysfunction and CRS.

Excessive daytime sleepiness in asthma: What are the risk factors?

OBJECTIVE

Previous studies have found that excessive daytime sleepiness (EDS) is a more common problem in asthmatic subjects than in the general population. The aim of this study was to investigate whether the prevalence of EDS is increased in asthmatic subjects and, if so, to analyse the occurrence of potential risk factors for EDS in asthmatics.

METHODS

Cross-sectional epidemiological study. In 2008, a postal questionnaire was sent out to a random sample of 45,000 individuals aged 16-75 years in four Swedish cities.

RESULTS

Of the 25,160 persons who participated, 7.3% were defined as having asthma. The prevalence of EDS was significantly higher in asthmatic subjects (42.1% vs. 28.5%, p < 0.001) compared with non-asthmatic subjects. Asthma was an independent risk factor for EDS (adjusted OR 1.29) and the risk of having EDS increased with asthma severity. Risk factors for EDS in subjects with asthma included insomnia (OR, 3.87; 95% CI, 3.10-4.84); chronic rhinosinusitis (OR, 2.00; 95% CI, 1.53-2.62); current smoking (OR, 1.60; 95% CI, 1.15-2.22) and obesity (OR, 1.53; 95% CI, 1.09-2.13).

CONCLUSIONS

EDS is a common problem among subjects with asthma. Asthma is an independent risk factor for having EDS. Furthermore, subjects with asthma often have other risk factors for EDS, many of them potentially modifiable.

Endoscopic Sinus Surgery Improves Sleep Quality in Chronic Rhinosinusitis: A Systematic Review and Meta-analysis

Objective Up to 75% of patients with chronic rhinosinusitis (CRS) suffer with poor sleep quality and reduced quality of life. Endoscopic sinus surgery has demonstrated encouraging results in improving sleep function. The aim of this systematic review is to assess the change in sleep quality after surgery for CRS. Data Sources PubMed, Web of Science, EMBASE. Review Methods An electronic search was conducted with the keywords "sinusitis" or "rhinosinusitis" and "sleep." Studies were included only when adults underwent endoscopic sinus surgery and were evaluated pre- and postoperatively by the Epworth Sleepiness Scale (ESS), the Pittsburgh Sleep Quality Index (PSQI), the Apnea-Hypopnea Index (AHI), the sleep domain of Sino-Nasal Outcome Test-22, or the sleep domain of Rhinosinusitis Disability Index. Results The database search yielded 1939 studies, of which 7 remained after dual-investigator screening. The standardized mean differences (95% CI) for the ESS, PSQI, and AHI were -0.94 (-1.63 to -0.26), -0.80 (-1.46 to -0.14), and -0.20 (-0.32 to -0.07), indicating large, moderate to large, and small improvements, respectively. All analyses displayed high heterogeneity ( I² = 95%-99%). Conclusion Sleep quality, as measured by the ESS and PSQI surveys, shows substantial improvement after surgery for CRS, with smaller improvement seen for AHI. Generalizability of our results is limited by high heterogeneity among studies and by broad confidence intervals that cannot exclude small to trivial changes. The findings of this meta-analysis provide insight into the effect of CRS-related endoscopic sinus surgery on sleep quality, which should guide future research direction and counseling of patients in the clinical setting.

LL-37 causes cell death of human nasal epithelial cells, which is inhibited with a synthetic glycosaminoglycan

LL-37 is an immune peptide that regulates innate and adaptive immune responses in the upper airways. Elevated levels of LL-37 have been linked to cell death and inflammatory diseases, such as chronic rhinosinusitis (CRS). Glycosaminoglycans (GAGs) are polysaccharides that are found on respiratory epithelial cells and serve important roles in mucosal surface repair. Recent findings suggest that a synthetic glycosaminoglycan (GM-0111) can protect against LL-37-induced sinonasal mucosal inflammation and cell death in a murine model of acute RS. Herein, we elucidated the mechanisms by which LL-37 causes sinonasal inflammation and how GM-0111 can prevent these mechanisms. When challenged with LL-37, human nasal epithelial cells (HNEpCs) and mouse macrophages (J774.2) demonstrated increased release of adenosine triphosphate (ATP) and interleukin (IL)-6 and -8, as well as cell death and lysis. These cellular responses were all blocked dose-dependently by pre-treatment with GM-0111. We identified that LL-37-induced cell death is associated with caspase-1 and -8 activation, but not activation of caspase-3/7. These responses were again blocked by GM-0111. Our data suggest that LL-37 causes cellular death of HNEpCs and macrophages through the pro-inflammatory necrotic and/or pyroptotic pathways rather than apoptosis, and that a GM-0111 is capable of inhibiting these pro-inflammatory cellular events.

Analysis of factors associated with electing endoscopic sinus surgery

OBJECTIVE

Medically refractory chronic rhinosinusitis (CRS) can be managed with appropriate continued medical therapy (CMT) or surgery followed by CMT. Patients who initially elect CMT and do not experience adequate symptom resolution may "cross over" to endoscopic sinus surgery (ESS). Our objective was to identify patient covariates associated with this subset of patients who elect this change in treatment modality.

STUDY DESIGN

Retrospective analysis of a prospective, multi-center cohort of adult patients with CRS enrolled between March 2011 and June 2015 in academic, tertiary referral clinics.

METHODS

Subjects who initially elected CMT were followed up to 18 months, provided a comprehensive medical history, and completed the 22-item SinoNasal Outcome Test (SNOT-22) at baseline and during 6-month follow-up intervals. Hazard regression modeling was used to identify covariates associated with elective change in treatment modality.

RESULTS

One hundred seventy-nine subjects were followed for an average 15.1 (standard deviation ± 4.6) months. Subjects who elected ESS (55 of 179) had significantly worse average endoscopy scores and reported worse SNOT-22 sleep dysfunction scores at baseline (P ≤ 0.026). For each single increasing (worsening) point of Lund-Kennedy endoscopy score, the hazard ratio (HR) of crossover increased by ∼6%. Similarly, for every point of worsening in baseline SNOT-22 total score, the hazard of treatment crossover increased by ∼2%. After covariate adjustment, only baseline SNOT-22 sleep dysfunction scores were associated with an increased risk of treatment crossover (HR = 1.07; 95% confidence interval: 1.02-1.11; P = 0.003).

CONCLUSION

Baseline total SNOT-22 and endoscopy scores are associated with treatment crossover, but reported sleep dysfunction is the only significant independent predictor of treatment crossover.

Impact of sinonasal disease on depression, sleep duration, and productivity among adults in the United States

Objective

Examine the relationship between depression symptoms and sinonasal inflammatory diseases, and investigate health disparities associated with allergic rhinitis (AR) and sinusitis in the United States.

Study Design

Cross‐sectional analysis of 2014 National Health Interview Survey (NHIS) data.

Methods

Adult cases of AR and sinusitis were extracted from the 2014 NHIS in addition to demographic, socioeconomic, and related depressive symptom data. The dataset was analyzed with chi‐square, t‐tests, and multivariate regression.

Results

There were 19.1 ± 1.1 million adult AR cases and 29.4 ± 1.4 million adult sinusitis cases. Of these, 20.6% and 22.0% reported depression symptoms in the past 12 months for those with AR or sinusitis, respectively. Both diseases were also associated with significantly fewer mean hours of sleep a night (AR: 7.02 vs. 7.14, P < 0.01; Sinusitis: 6.98 vs. 7.14, P < 0.01) and greater mean days of work missed (AR: 4.60 vs. 3.62, P < 0.01; Sinusitis: 5.87 vs. 3.41; P < 0.01). On multivariate analysis, the prevalence of AR and sinusitis was significantly higher among men, Caucasians, older adults, the more educated, and adults with depression symptoms. Only the prevalence of sinusitis varied depending on income and geography.

Conclusion

Allergic rhinitis and sinusitis are associated with an increased likelihood of depressive symptoms, shorter sleep duration, and more workdays lost. The prevalence of both are influenced by age, sex, race/ethnicity, and education level. Targeted initiatives should be developed to address these health disparities and comorbidities associated with inflammatory sinonasal disease.

Economics of Chronic Rhinosinusitis

PURPOSE OF REVIEW

The objective of this article is to provide an updated review of the economic burden of chronic rhinosinusitis (CRS) and discuss how both medical and surgical interventions impact direct and indirect costs related to CRS. By understanding the economics of CRS, clinicians may improve the patient-centeredness of their care and help distinguish between low and high value interventions.

RECENT FINDINGS

Direct costs related to CRS are primarily driven by outpatient physician visits, prescription medical therapy, and endoscopic sinus surgery (ESS). CRS produces large indirect costs and these costs often vary based on the severity of the patients CRS-specific QoL impairment. The overall direct cost related to CRS is estimated to range between $10 and $13 billion per year in the USA. The overall indirect cost related to CRS-related losses in work productivity is estimated to be in excess of $20 billion per year. In the appropriate patients with refractory CRS, ESS provides significant reductions in both direct and indirect costs; however, continued medical therapy alone may be a high value intervention in select patients who have lower severity in their baseline QoL and work productivity.

Mortality risk in patients with chronic rhinosinusitis and its association to asthma

BACKGROUND

Chronic rhinosinusitis (CRS) is a highly prevalent inflammatory condition, with significant effects on morbidity and quality of life. Given that other chronic inflammatory conditions have been associated with increased mortality risk, we sought to evaluate the relationship between mortality and CRS including the influence of asthma. Our objective was to determine if CRS, with or without asthma, is associated with altered risk of mortality.

METHODS

Using a statewide population database, we retrospectively identified 27,005 patients diagnosed with CRS between 1996 and 2012, and 134,440 unaffected controls matched 5:1 on birth year and sex. Risk of mortality was determined from Cox models and Kaplan-Meier curves were used to compare survival.

RESULTS

A significant interaction between CRS and asthma status was observed in which CRS appeared to confer a protective effect in asthma patients. Asthma, when present, increased mortality in CRS-negative controls (p-interaction < 0.0001). Independent of asthma status, CRS patients exhibited a decreased mortality risk (hazard ratio [HR] = 0.80; 95% confidence interval [CI], 0.74 to 0.85) compared to controls. However, in patients diagnosed at or before the median age of CRS onset (42 years) independent of asthma status, survival was not improved (HR = 0.98; 95% CI, 0.81 to 1.18). Risk of mortality was greater in CRS with nasal polyps (n = 1643) compared to 25,362 polyp-negative CRS patients (HR = 1.38; 95% CI, 1.09 to 1.77).

CONCLUSION

CRS was associated with lower risk of mortality compared to controls, and appeared to mitigate increased mortality from asthma. We posit that better survival conferred by CRS may be secondary to treatment. However, the etiology of this relationship and the effect of CRS treatment on mortality are unknown.

Chronic rhinosinusitis: Epidemiology and burden of disease

BACKGROUND

Chronic rhinosinusitis (CRS) is based on sinonasal symptoms coupled with sinonasal tissue inflammation. Establishing the epidemiology and prevalence of CRS, therefore, is challenging given that confirming objective evidence of sinonasal inflammation on a large scale is not feasible. Although the sinonasal symptoms are well documented at the sinonasal level, analysis of emerging data indicates that the impact on the general-health-related domains of health are the symptoms that are most bothersome to patients' quality of life.

OBJECTIVE

To review the literature on the epidemiology and the societal and individual burdens of CRS.

METHODS

A literature review.

RESULTS

A refinement of questionnaire-based surveys coupled with sampling of respondents for accuracy likely provides the most accurate assessment of prevalence. There is geographic variation, but, in North American and European countries, the rates range from 4.5 to 12%. Although CRS is marked by sinonasal symptoms, the most problematic symptoms for patients seem to be the symptoms that affect general-health-related domains. Diminished sleep, productivity, cognition, mood, and fatigue are associated with the decision to elect surgical intervention and are associated with diminished healthy utility values. Direct costs of CRS have been well documented, but new data on the indirect costs of decreased productivity surpass direct costs, at $12.8 billion dollars per year in the United States.

CONCLUSION

CRS is a common disease with a large and vast symptom burden with high indirect costs. Although clinicians are focused by guidelines on sinus-specific symptoms, patients seem to be most impacted by the general-health-related consequences of CRS. An expanded understanding of the extent and costs of these symptoms will allow for a cost-effective allocation of limited health care resources.

Sleep quality outcomes after medical and surgical management of chronic rhinosinusitis

BACKGROUND

Endoscopic sinus surgery (ESS) has been shown to improve sleep in patients with chronic rhinosinusitis (CRS). However, it is unknown how this improvement compares with non-CRS control subjects' sleep, and medically treated CRS patients.

METHODS

Patients meeting diagnostic criteria for CRS and controls from the same reference population were recruited from 4 academic centers. Patients chose either medical or surgical treatment. The Pittsburgh Sleep Quality Index (PSQI) was administered to patients before treatment and after 6 months, whereas controls received the PSQI at enrollment.

RESULTS

The study population consisted of 187 cases (64 medical and 123 surgical) and 101 controls. Baseline PSQI scores for CRS patients (9.27 ± 4.76) were worse than for controls (5.78 ± 3.25), even after controlling for potential confounding factors such as asthma and allergy (p < 0.001). There was no significant difference in baseline PSQI between patients choosing medical vs surgical treatment. The PSQI score in surgical patients improved from 8.36 ± 5.05 to 7.44 ± 5.09 (p = 0.020). The PSQI score in medical patients demonstrated a nonsignificant increase with treatment from 8.71 ± 4.48 to 9.06 ± 4.80 (p = 0.640). After controlling for allergy and asthma, 6-month PSQI scores in medical patients remained significantly higher than in controls (p = 0.001), whereas a significant difference could not be demonstrated between surgical patients and controls (p > 0.05). PSQI subdomain analysis mirrored the overall findings.

CONCLUSION

Patients with CRS report worse sleep compared with controls. Surgically treated CRS patients show significant improvement in PSQI scores, whereas those continuing with medical management fail to improve and remain worse than controls.

The pain-depression dyad and the association with sleep dysfunction in chronic rhinosinusitis

BACKGROUND

Depression, pain, and sleep disturbance is a symptom cluster often found in patients with chronic illness, exerting a large impact on quality of life (QOL). A wealth of literature exists demonstrating a significant association between depression, pain, and sleep dysfunction in other chronic diseases. This relationship has not been described in patients with chronic rhinosinusitis (CRS).

METHODS

Sixty-eight adult patients with CRS were prospectively enrolled. Patients at risk for depression were identified using the Patient Health Questionnaire-2 (PHQ-2) using a cut-off score of ≥1. Pain experience was measured using the Brief Pain Inventory Short Form (BPI-SF) and the Short Form McGill Pain Questionnaire (SF-MPQ). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI).

RESULTS

Forty-seven patients were at risk for depression. Significant positive correlations were found between total PSQI scores and all pain measures (R = 0.38-0.61, p ≤ 0.05) and between total PSQI scores and PHQ-2 scores (R = 0.46, p < 0.05). For patients at risk for depression, significant, positive correlations were found between pain measures, the total PSQI score, and the 3 PSQI subdomains (sleep latency, sleep quality, and daytime dysfunction; R = 0.31-0.61, p < 0.05). The relationship between pain and sleep dysfunction scores was not seen in the absence of depression.

CONCLUSION

Depression, pain, and sleep dysfunction are interrelated in patients with CRS. In the absence of depression, significant correlations between pain and sleep are not observed, suggesting that depression plays a key role in this interaction. Further research is needed to investigate the complex relationship between depression, pain, and sleep dysfunction in CRS.

Endoscopic sinus surgery improves cognitive dysfunction in patients with chronic rhinosinusitis

BACKGROUND

Patients with chronic rhinosinusitis (CRS) have been found to have cognitive deficit, as identified using the Cognitive Failures Questionnaire (CFQ), but the exact etiology of cognitive decline is unknown. In this study we aimed to determine whether improvement in concomitant inflammation and disease burden in CRS, using endoscopic sinus surgery (ESS), improves cognitive deficit. We also sought to identify comorbid conditions that effect improvement likelihood.

METHODS

Study participants (n = 247) with and without nasal polyposis (CRSwNP, CRSsNP) were prospectively enrolled in this multi-institutional, observational outcomes study. Pre- and postoperative cognitive dysfunction was evaluated using the CFQ instrument. Quality of life (QOL) and disease burden was also evaluated using the Rhinosinusitis Disability Index (RSDI), the 22-item SinoNasal Outcome Test (SNOT-22), nasal endoscopy, computed tomography, and the 2-item Patient Health Questionnaire (PHQ-2).

RESULTS

Average CFQ total scores improved significantly (p = 0.012) after ESS for patients with follow-up (n = 141). Participants with CRSwNP (n = 51) reported significant postoperative improvements in mean CFQ total scores (p = 0.002) and CFQ distractibility and blunders domain scores (p ≤ 0.006). No significant postoperative improvement for any average CFQ score was found in CRSsNP (p > 0.086). The magnitude of postoperative improvement in CFQ total and domain mean scores was statistically similar between CRSsNP and CRSwNP (p > 0.115). Depressive disorder, identified using PHQ-2 screening, was the only comorbid condition significantly associated with measurable cognitive deficit (p < 0.001).

CONCLUSIONS

Patients with CRS have measurable cognitive decline, and ESS may modestly improve cognitive deficit/CFQ scores. Future investigations are needed to further elucidate the underlying mechanisms responsible for cognitive deficit in patients with CRS and significant associations with depression.

Differences in the Sino-Nasal Outcome Test 22 and Visual Analog Scale Symptom Scores in Chronic Rhinosinusitis with and without Nasal Polyps

Background

Chronic rhinosinusitis (CRS) with and without polyps has a high impact on health-related quality of life (HRQL), but the difference in HRQL and symptom presentation between two clinical phenotypes of CRS has not been specifically evaluated before now.

Objective

To evaluate patterns of symptoms and HRQL disease-specific domains affected in patients with CRS by comparing differences between two clinical phenotypes, adjusted for demographics, major risk factors, comorbidities, current medical treatment, and previous surgery.

Methods

A group of 251 patients with CRS completed the visual analog scale (VAS) symptom severity score and the Sino-Nasal Outcome Test 22 (SNOT-22) questionnaire. Data sets were analyzed by using principal component analysis (PCA) to identify a set of symptom components, together with the items excluded from PCA, which were then analyzed for differences between patients with CRS with nasal polyps (CRSwNP) and patients with CRS without nasal polyps (CRSsNP).

Results

PCA of SNOT-22 items identified six components, three referred to CRS-specific symptoms termed “nasal”; “extranasal, rhinologic”; and “olfactory/cough”; and three referred to HRQL impairment termed “sleep disturbance,” “functional disturbance,” and “emotional disturbance.” Nasal obstruction, ear pain, ear fullness, and fatigue were excluded from PCA and treated as separate outcomes. Patients with CRSwNP had significantly worse nasal symptoms, olfactory/cough symptoms, and nasal obstruction. Patients with CRSsNP scored significantly worse with regard to fatigue and to sleep and functional disturbances. The PCA results for VAS scores identified three symptom components: pain, nasal symptoms, and pharyngeal symptoms. Patients with CRSwNP had significantly worse VAS nasal symptoms but less pronounced VAS pain symptoms than patients with CRSsNP. The total SNOT-22 score between the groups was not significantly different.

Conclusion

With controlling of covariates that may influence the severity of the disease, this study showed significant differences in symptom patterns and different aspects of HRQL impairment between patients with CRSwNP and patients with CRSsNP, however, with no difference in the total HRQL score.

Dyad of pain and depression in chronic rhinosinusitis

BACKGROUND

Pain and depression often coexist as comorbidities in patients with chronic disease and exert a major impact on quality of life (QOL). Little is known about the relationship between pain and depression in chronic rhinosinusitis (CRS). Our objective was to investigate this relationship and to analyze the effect of pain and depression on QOL in CRS.

METHODS

Patients with CRS were prospectively recruited as part of an observational cohort study. A total of 70 participants provided pain scores using both the Brief Pain Inventory Short Form (BPI-SF) and the Short Form McGill Pain Questionnaire (SF-MPQ). Patients at risk for depression were identified using the Patient Health Questionnaire-2 (PHQ-2). CRS-specific QOL was determined using the 22-item Sino-Nasal Outcome Test (SNOT-22).

RESULTS

Significant positive correlations were found between depression scores and all pain measures (R = 0.475 to 0.644, p < 0.001). Patients with a PHQ-2 score ≥1 had significantly higher scores on all reported pain measures. Significant positive correlations were found between all pain measures, the total SNOT-22 score, and 3 SNOT-22 subdomains (sleep, psychological dysfunction, and ear/facial symptoms; R = 0.323 to 0.608, p < 0.05).

CONCLUSION

Adult patients with CRS at risk for depression experience more pain and have overall worse disease-specific QOL. Further research investigating the complex interactions between depression and pain and the role it plays in CRS disease-specific QOL is warranted.

Risk factors for sleep impairment in adult patients with chronic rhinosinusitis

OBJECTIVE

Although sleep impairment is reported by patients with chronic rhinosinusitis, the associated factors have not been well studied. Therefore, we determined the associated risk factors for sleep impairment in patients with chronic rhinosinusitis (CRS).

METHODS

This study was a prospective cohort study. A total of 572 adult patients (171 women, 401 men; mean age, 49.0 years; range, 18-64 years) who completed a questionnaire, had a clinical examination, and underwent endoscopic sinus surgery were analyzed using stepwise multiple linear regression.

RESULTS

With regard to subjective symptoms, nasal obstruction (beta coef., 0.27; p<0.001), anterior nasal drainage (beta coef., 0.13; p=0.004), facial pain/pressure (beta coef., 0.09; p=0.048), headache (beta coef., 0.10; p=0.010), and cough (beta coef., 0.14; p<0.001) were predictors of an increased risk of sleep impairment of CRS (adjusted R(2), 0.240; p=0.048). In the matter of background parameters, total polyp score (polyp grading system) (beta coef., 0.16; p<0.001) and allergic rhinitis (beta coef., 0.09; p=0.034) were predictors of an increased risk of sleep impairment of CRS (adjusted R(2), 0.029; p=0.034).

CONCLUSION

These results suggest that sleep impairment in these patients is caused by the various mechanisms associated with nasal symptoms themselves, CRS and allergic rhinitis. However, the specific pathophysiology has not been clarified yet; further studies are expected to elucidate that of sleep impairment in patients with CRS.

Geographic Variation of Endoscopic Sinus Surgery in Canada: An Alberta-Based Small Area Variation Analysis

OBJECTIVE

With an estimated 10,000 to 15,000 endoscopic sinus surgery (ESS) cases performed in Canada each year, identifying potential unwarranted practice patterns is important. The objective of this study is to examine the rates and geographic variation of ESS in the province of Alberta, Canada.

STUDY DESIGN

Small area variation analysis.

SETTING

Province of Alberta, Canada.

SUBJECTS AND METHODS

The National Ambulatory Care Reporting System database was searched to identify all patients who received ESS between April 1, 2010, and March 31, 2013, in Alberta, Canada. The annual adjusted rates of ESS per 1000 people were calculated for each Alberta health zone and health status area. Geographic variations were evaluated with the extremal quotient, weighted coefficient of variation, and systematic component of variance. Chi-squared-test was used to quantify the significance of variation of the adjusted ESS rates across regions.

RESULTS

The annual adjusted rate of ESS was 0.33 per 1000 people in Alberta, Canada. The mean extremal quotient for health status areas was 6.9, indicating a 7-fold difference between the highest and lowest regions. The mean coefficient of variation was 41.0, and the mean systematic component of variance was 10.5, which demonstrates "very high" variation.

CONCLUSION

This study observed very high geographic variation in the rates of ESS across the province of Alberta. Given the negative impact of unwarranted surgical variation on quality of care, outcomes from this study indicate a need to further evaluate the delivery of care for ESS in Canada to improve overall health system performance.

Characterization of facial pain associated with chronic rhinosinusitis using validated pain evaluation instruments

BACKGROUND

Prior investigations into facial pain associated with chronic rhinosinusitis (CRS) have yielded important results, but have yet to use pain-specific outcome measures. This study seeks to characterize facial pain associated with CRS using validated pain-specific instruments.

METHODS

Adults with CRS were enrolled into a prospective, cross-sectional study along with control participants presenting with non-CRS diagnoses. Facial pain was characterized in both groups using the Brief Pain Inventory Short Form (BPI-SF) and the Short-Form McGill Pain Questionnaire (SF-MPQ). CRS-specific measures of disease were measured including the 22-item Sino-Nasal Outcome Test-22 (SNOT-22), nasal endoscopy, and computed tomography scoring.

RESULTS

The patients comprised of CRS with nasal polyposis (CRSwNP; n = 25), CRS without nasal polyposis (CRSsNP; n = 30), and control participants (n = 8). Subjects with CRSwNP and CRSsNP were less likely to be pain free than controls (16.0%, 6.7%, and 62.5% respectively, p = 0.001) and carried greater burden of pain as measured by the BPI-SF and SF-MPQ than controls (p = 0.002 and p = 0.017, respectively). Pain in CRS was most commonly located around the eyes and characterized as "throbbing" and "aching." Nasal polyp status was not associated with differences in character, severity, or location of pain.

CONCLUSION

Subjects with CRS have a greater burden of facial pain relative to control subjects across several standardized pain measures. Further, facial pain in CRS significantly correlated to quality of life and CRS-specific disease severity measures. Study across larger cohorts using standardized pain measures is warranted to clarify the association of facial pain with CRS.

The impact of endoscopic sinus surgery on total direct healthcare costs among patients with chronic rhinosinusitis

BACKGROUND

This study investigates how endoscopic sinus surgery (ESS) impacts total direct healthcare costs, medication usage, and frequency of imaging among patients with chronic rhinosinusitis (CRS).

METHODS

Data were obtained from the MarketScan® Commercial Claims and Encounters databases (Truven Health Analytics); patients who underwent ESS for CRS in 2008 were identified. Healthcare costs, days of antibiotic and oral steroid usage, and number of computed tomography (CT) and magnetic resonance imaging (MRI) studies were collected for 12 months prior to and 36 months after surgery and compared in 1-year intervals.

RESULTS

A total of 8963 surgical patients were included. Median total direct costs fell from $4750 at preoperative baseline (95% confidence interval [CI], $4661 to $4838) to $4212 by year 3 after surgery (95% CI, $4078 to $4346). Disease-specific costs related to conditions commonly associated with CRS-asthma, allergy, depression, and headache-all decreased in the years after surgery; the reduction was significant for all conditions but asthma. Mean days of antibiotic usage per year decreased from 28.2 days before surgery to 15.9 days by year 3 after surgery, p value <0.001. Days of oral corticosteroid usage remained stable at just over 7 days. Mean number of imaging studies fell from an average of 1.6 in the year before surgery to 0.2 by year 3 after surgery, p value <0.001.

CONCLUSION

Among patients who underwent ESS for CRS, total direct healthcare costs, antibiotic usage, and number of imaging studies decreased after surgery, and remained below preoperative levels throughout all 3 years of follow-up. Oral corticosteroid usage remained stable.
