Objective Acute exacerbation of chronic rhinosinusitis (AECRS) is associated with significant quality-of-life decreases. We sought to determine characteristics associated with an exacerbation-prone phenotype in chronic rhinosinusitis (CRS). Study Design Cross-sectional. Setting Tertiary care rhinology clinic. Subjects Patients with CRS (N = 209). Methods Patient-reported number of sinus infections, CRS-related antibiotics, and CRS-related oral corticosteroids taken in the last 12 months were used as metrics for AECRS frequency. Sinonasal symptom burden was assessed with the 22-item Sinonasal Outcome Test (SNOT-22). Ninety patients reporting 0 for all AECRS metrics were considered to have had no AECRS in the prior 12 months. A total of 119 patients reported >3 on at least 1 AECRS metric and were considered as having an exacerbation-prone phenotype. Characteristics associated with patients with an exacerbation-prone phenotype were identified with exploratory regression analysis. Results An exacerbation-prone phenotype was positively associated with comorbid asthma (adjusted odds ratio [ORadj] = 3.68, 95% CI: 1.42-9.50, P = .007) and SNOT-22 (ORadj = 1.06, 95% CI: 1.04-1.09, P < .001). Polyps were negatively associated (ORadj = 0.27, 95% CI: 0.11-0.68, P = .005) with an exacerbation-prone phenotype. SNOT-22 score ≥24 identified patients with an exacerbation-prone phenotype with a sensitivity of 93.3% and a specificity of 57.8%. Having either a SNOT-22 score ≥24 with a nasal subdomain score ≥12 or a SNOT-22 score ≥24 with an ear/facial discomfort subdomain score ≥3 provided >80% sensitivity and specificity for detecting patients prone to exacerbation. Conclusions In total, these results point to a CRS exacerbation-prone phenotype characterized by high sinonasal disease burden with comorbid asthma but interestingly without polyps.

Background Chronic rhinosinusitis (CRS) is often differentiated by histopathologic phenotypes (eosinophilic versus neutrophilic), which may impact disease severity measures and outcomes. As such, it has been suggested that counts of cellular elements be included as part of a standard pathological report following endoscopic sinus surgery (ESS). Objectives This cross-sectional study evaluated associations of mucosal eosinophilia and neutrophilia with measures of quality-of-life (QoL) and olfactory function. Methods Patients with medically refractory CRS completed the SNOT-22 survey and Brief Smell Identification Test (BSIT) at enrollment. In addition, baseline Lund-Mackay computed tomography (CT) and Lund-Kennedy endoscopy scores were collected. Ethmoid mucosa was biopsied during ESS and reviewed using microscopy to quantify densest infiltrate of eosinophils or neutrophils per high-powered-field (HPF). Eosinophilic CRS (eCRS) and neutrophilic CRS (nCRS), both with and without nasal polyposis (NP), were compared across SNOT-22 and BSIT scores. Results 77/168 patients demonstrated mucosal eosinophilia (eCRS) while a total of 42/168 patients demonstrated mucosal neutrophilia (nCRS). After adjusting for polyp status, 35/168 had eCRSsNP, 42/168 eCRSwNP, 75/168 non-eCRSsNP, 16/168 non-eCRSwNP. Additionally, 22/161 were noted to have nCRSsNP, 20/161 nCRSwNP, 84/161 non-nCRSwNP, and 35/161 non-nCRSsNP. A small subset of patients demonstrated both eosinophilia and neutrophilia: 14 CRSwNP and 7 CRSsNP. When evaluating average Lund-Mackay Scores (LMS), significant differences existed between non-eCRSsNP and eCRSsNP (p = 0.006). However, after controlling for nasal polyps, eosinophilia did not significantly associate with differences in the Lund-Kennedy Score. Neutrophilia did not significantly associate with any changes in LMS or LKS after controlling for NP. Eosinophilic and neutrophilic histopathologic subtypes did not significantly associate with differences in baseline SNOT-22 or BSIT measures after controlling for NP. Conclusion Neither the presence of mucosal eosinophilia nor mucosal neutrophilia demonstrated significant associations with SNOT-22 quality-of-life or BSIT olfactory function scores when controlling for comorbid nasal polyposis.

Objectives: Functional endoscopic sinus surgery (FESS) is a standard treatment modality for patients with chronic rhinosinusitis (CRS) who have failed appropriate medical therapy. However, FESS entails modification of the upper airway tract that may alter phonatory resonance and produce voice changes. The effects of FESS on postoperative voice characteristics in patients with CRS have yet to be quantitatively assessed. Methods: Patients with severe CRS who underwent FESS at a tertiary care referral center between May and October 2017 were prospectively enrolled. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and the Voice Handicap Index (VHI) were used to quantitatively evaluate voice characteristics and quality of life, respectively. Preoperative and postoperative CAPE-V and VHI scores were compared with postoperative scores for each patient. Sino-Nasal Outcome Test (SNOT-22) scores were also obtained to assess changes in patient symptoms. Results: 18 CRS patients undergoing FESS were enrolled. The average preoperative Lund-Mackay score was 14, indicating baseline severe CRS. Postoperative assessments demonstrated a statistically significant decrease in CAPE-V (45-27, p = .005) and VHI (10-4.7, p < .001) scores. These correlated with a statistically significant decrease in SNOT-22 scores (42-13, p < .001). Conclusions: Patients with CRS experience a significant improvement in voice characteristics and vocal quality of life following FESS. Furthermore, this appears to correlate with a significant decrease in self-reported disease severity. These findings may augment the discussion of potential benefits of FESS to a new potential domain for voice quality.

Background Common rhinologic diagnoses have similar presentations with a varying degree of overlap. Patterns may exist within clinical data that can be useful for early diagnosis and predicting outcomes. Objective To explore the feasibility of artificial intelligence to differentiate patterns in patient data in order to develop clinically-meaningful diagnostic groups. Methods A cross-sectional study of prospectively-acquired patient data at a tertiary rhinology clinic was performed. Data extracted included objective findings on nasal endoscopy, patient reported quality of life (PRQOL) instrument ratings, peripheral eosinophil fraction, and past medical history. Unsupervised non-hierarchical cluster analysis was performed to discover patterns in the data using 22 input variables. Results A total of 545 patients were analyzed after application of inclusion and exclusion criteria yielding 7 unique patient clusters, highly dependent on PRQOL scores and demographics. The clusters were clinically-relevant with distinct characteristics. Chronic rhinosinusitis without nasal polyposis (CRSsNP) was associated with two clusters having low frequencies of asthma and low eosinophil fractions. Chronic rhinosinusitis with nasal polyposis (CRSwNP) was associated with high frequency of asthma, mean (standard deviation [SD]) NOSE scores of 66 (19) and SNOT-22 scores of 41 (15), and high eosinophil fractions. AR was present in multiple clusters. RARS was associated with the youngest population with mean (SD) NOSE score of 54 (23) and SNOT-22 score of 41 (19). Conclusion Broader consideration of initially available clinical data may improve diagnostic efficiency for rhinologic conditions without ancillary studies, using computer-driven algorithms. PRQOL scores and demographic information appeared to be useful adjuncts, with associations to diagnoses in this pilot study.

Background Quality of life (qol) is important for oncology patients, especially for those with late-stage disease. The present study was initiated to address the lack of published prospective data about the qol benefits of trifluri­dine/tipiracil (tfd/tpi) compared with best supportive care (bsc) in patients with refractory metastatic colorectal cancer (mcrc). Methods This prospective, cross-sectional, non-interventional study used multidimensional validated scales to evaluate patient-reported qol in two study cohorts of patients and also to measure differences in mcrc-related symptoms and pain in a real-world clinical setting. Results Our findings demonstrate that patients with refractory mcrc report better overall qol when treated with tfd/ tpi than with bsc alone. In that population, statistically significant differences in mean qol measures favoured tfd/tpi over bsc for physical symptom distress, psychological distress, activity impairment, overall valuation of life, and symptomatology. The overall better qol for patients receiving tfd/tpi implies that treatment was well tolerated and was associated with a lower symptom burden. No significant differences for pain were observed between the groups. Conclusions This study suggests that tfd/tpi is a well-tolerated option for the treatment of patients with refractory mcrc, showcasing the value of capturing real-world qol data in routine clinical practice.

Background: Chronic rhinosinusitis (CRS) is an inflammation of the nasal and paranasal sinuses mucosa, ongoing for more than 12 weeks. Even now it still creates socioeconomic problem in both developed and developing countries. Pharmacotherapy administration is essential for decreasing the severity of symptom, improving quality of life, and decreasing interleukin (IL)-6 level. Objective: To find out the effect of pharmacotherapy on severity of the symptom, quality of life, and IL-6 level. Method: Randomized clinical trial with pre and posttest design, on 20 CRS without polyp patients, divided into two groups based on skin prick test results. Both groups were equally treated with nasal irrigation, nasal corticosteroid, and antibiotic amoxicillin clavulanate for 14 days. All subjects were assessed for Visual Analog Scale (VAS) score, nasoendoscopy (NE) score, Sinonasal Outcome test (SNOT)-22, and IL-6 level. Statistical analysis was performed with Mann Whitney and Wilcoxon methods. Result: There were significant differences in total analysis results on VAS scores, NE scores, SNOT-22, and IL-6 levels in both groups, with values p<0.05. There was improvement in all variables after pharmacotherapy, but there was no significant difference between the case and control groups, with values p>0.05. Conclusion: Pharmacotherapy in both groups resulte’ in reduced severity of symptoms, improved quality of lives, and decreased IL-6 levels.Keywords: Interleukin-6, pharmacotherapy, chronic rhinosinusitis without polyp, quality of life ABSTRAK Latar belakang: Rinosinusitis kronik (RSK) merupakan inflamasi pada mukosa hidung dan sinus paranasal, yang berlangsung selama lebih dari 12 minggu.

Objective The objective of this study was to determine whether depression and anxiety symptoms affect and confound scoring on the 22-item Sinonasal Outcome Test (SNOT-22), a commonly used outcome measure for chronic rhinosinusitis. Study Design Prospective cross-sectional. Setting Tertiary care academic center. Methods 240 participants completed the SNOT-22, from which nasal, sleep, ear/facial pain, and emotional subdomain scores were calculated. They also completed the 8-item Patient Health Questionnaire (PHQ-8) as a reflection of depression symptoms and 7-item Generalized Anxiety Disorder (GAD-7) questionnaire as a reflection of anxiety symptoms. Correlations were calculated between the 4 SNOT-22 subdomains and the PHQ-8 and GAD-7. Additionally, the predictive ability of subdomains and individual items of the SNOT-22 to predict depression and anxiety was calculated. Results The SNOT-22 sleep and emotional subdomains most strongly correlated with the PHQ-8 and the GAD-7. The emotional and sleep subdomain scores were predictive of having depression or anxiety. An emotional subdomain score ≥4 had 62.5% sensitivity and 90.1% specificity for detecting depression and 78.8% sensitivity and 88.9% specificity for detecting anxiety. A sleep subdomain score ≥21 had 81.2% sensitivity and 71.4% specificity for detecting depression and 87.9% sensitivity and 68.6% specificity for detecting anxiety. The emotional subdomain item related to sadness and the sleep subdomain items related to functional impairment were most predictive of depression and anxiety. Conclusion The SNOT-22 emotional and sleep subdomain scores may be used to predict active depression and anxiety symptoms, especially when items related to sadness or functional impairment are scored with moderate burden.

Background: Disease control is an important treatment goal for chronic uncurable conditions such as chronic rhinosinusitis (CRS). The objective of this study was to determine whether patient-reported CRS disease control is a valid reflection of disease burden. Methods: Prospective longitudinal study of 300 CRS patients (35% CRS with nasal polyps, 65% CRS without nasal polyps). At enrollment and at a subsequent follow-up timepoint, all participants were asked to rate their CRS disease control as “not at all,” “a little,” “somewhat,” “very,” or “completely”, as well as to complete a 22-item Sinonasal Outcome Test (SNOT-22) and the 5-dimension EuroQol general health questionnaire from which the visual analogue scale (EQ-5D VAS) was used. Results: At enrollment and follow-up timepoints, patient-reported CRS disease control was significantly correlated with SNOT-22 and EQ-5D VAS scores. The change in patient-reported CRS disease control was significantly correlated with change in SNOT-22 and change in EQ-5D VAS scores. There was significant cross-sectional and longitudinal correlation between patient-reported control and all SNOT-22 subdomain scores. A SNOT-22 score of ≤ 25 points or lower, or an EQ-5D VAS score of ≥77 was predictive of having well - (i.e. “very” or “completely”) controlled CRS. Conclusions: Patient-reported CRS disease control is a valid measure of CRS disease burden and general QOL. A patient-reported assessment of CRS disease control could be considered as a component of a more comprehensive measure of CRS disease control.

Objective We sought to determine if chronic rhinosinusitis (CRS) patients with nasal polyps (CRSwNP) differentially perceived CRS symptom burden compared to patients without nasal polyps (CRSsNP) and to what extent CRS symptom severity was associated with quality of life (QOL) and patient-reported symptom control in the 2 groups. Methods A total of 600 patients (266 CRSwNP and 334 CRSsNP) presenting with CRS were recruited. CRS symptom burden was assessed with the 22-item Sinonasal Outcome Test (SNOT-22). SNOT-22 nasal, sleep, ear/facial discomfort, and emotional subdomain scores were calculated. General health-related QOL was assessed with the visual analog scale of the 5-dimensional EuroQol questionnaire (EQ-5D VAS). Patients rated their CRS symptom control on a 5-point scale. Results SNOT-22 scores did not differ between CRSwNP (mean: 35.6) and CRSsNP (mean: 36.3). There were no differences in nasal, sleep, and emotional subdomains of the SNOT-22. CRSsNP had higher ( P = .003) ear/facial subdomain scores than CRSwNP, while CRSwNP reported greater hyposmia ( P < .001). EQ-5D VAS was significantly lower ( P = .011) in CRSsNP (mean: 68.9) compared to CRSwNP (mean: 73.2). However, CRSwNP patients reported significantly less symptom control, compared to CRSsNP, in association with nasal and emotional symptoms. Conclusion CRSwNP and CRSsNP have differences in symptom profile, effect on health-related QOL, and patient-perceived symptom control. CRSsNP experience significantly greater burden of ear/facial discomfort, while CRSwNP report greater hyposmia. Although CRSsNP reports lower general health-related QOL overall, CRSwNP patients had lower levels of CRS symptom control for every incremental increase in symptom burden suggesting greater sensitivity/intolerance to CRS symptoms.

Background The 22-item Sinonasal Outcome Test (SNOT-22) is a validated patient-reported outcome measure for chronic rhinosinusitis and in many circumstances is used in rhinology/otolaryngology clinics to assess sinonasal symptoms in general when a formal diagnosis is not established, although with little support for such usage. Objective To assess the utility of the SNOT-22 as a reflection of quality of life (QOL) and symptom control for patients with allergic rhinitis (AR). Methods Retrospective review of 353 patients with persistent AR. Each patient completed a SNOT-22, 5-item EuroQol general health-related QOL (EQ-5D) questionnaire (from which the visual analog scale [VAS] was used), and Rhinitis Control Assessment Test (RCAT). In addition, 95 patients also completed these questionnaires 1 to 12 months later. Results The SNOT-22 was negatively correlated with the EuroQol 5-dimensional visual analog scale (EQ-5D VAS; r = −.45, 95% confidence interval [CI]: −0.53 to −0.36, P < .001) and RCAT ( r = −.62, 95% CI: −0.68 to −0.55, P < .001), with excellent internal consistency. The SNOT-22 demonstrated responsiveness, with mean change of −5.8 (95% CI: −8.9 to −2.6, P < .001) from pre- to posttreatment. The change in SNOT-22 over the treatment period was correlated with change in EQ-5D VAS ( r = −.28, 95% CI: −0.46 to −0.07, P = .008) and RCAT ( r = −.56, 95% CI: −0.69 to −0.41, P < .001). The minimal clinically important difference was calculated to be between 6 and 11. Conclusion The SNOT-22 has utility to assess QOL and symptom control in AR, and it is both reliable and responsive in its application to patients with AR. The SNOT-22 may therefore be a convenient and versatile tool in the clinical assessment of patients with AR.

Background: The Sinonasal Outcome Test (SNOT-22) has been used as a patient reported outcome measure to grade symptom severity before and after treatment for chronic rhinosinusitis (CRS). Methodology: This analysis uses data from the CRS Epidemiology Study (CRES). The overarching aim of CRES was to determine factors that influence the onset and severity of CRS. A study-specific questionnaire including SNOT-22 was distributed to patients with CRS attending ENT clinics across 30 centres in the United Kingdom. The aim of this analysis was to compare SNOT-22 scores between those with different types of CRS to determine any differences present in the total score or the subdomains and to assess whether any differences varied according to gender. Results: There were a total of 1249 CRS participants in the following subgroups: CRS without nasal polyps (CRSsNPs) (n=553), CRS with nasal polyps (CRSwNPs) (n=651), allergic fungal rhinosinusitis (AFRS) (n=45). Since there were differing gender ratios in each subgroup, males and females were analysed separately. The mean and standard deviation for SNOT-22 was: males CRSsNP 41.1 (21.0), CRSwNP 41.7 (20.5); females CRSsNP 49.6 (19.7), CRSwNP 49.5 (22.9). In the nasal domain, those with CRSwNP scored more highly than those with CRSsNP; for males 18.1 (8.1) vs. 15.9 (7.9); for females 19.6 (8.0) vs 16.7 (7.5). Conclusions: Patients with CRSwNPs report higher symptom scores in the nasal domain of SNOT-22 than those with CRSsNPs with women in both subgroups reporting higher total scores than men.
