Cross-sensitization between inhalant allergens and food allergens: the extent, intensity, and age-related shifts.

BACKGROUND: Encountering individuals sensitized to both inhalant and food allergens is challenging in clinical practice. Despite its rarity, studies have documented cross-sensitization between these allergens. However, the extent, diversity, and age-related variations of this phenomenon remain unclear. OBJECTIVE: Hence, our objective was to investigate a substantial quantity of allergy sensitivity test results in which both inhalant and food allergens were concurrently examined. The primary goal of our study is to calculate the cross-sensitization ratio, with a secondary objective of analyzing this phenomenon across four age groups. METHODS: A retrospective analysis was conducted on a multiple-antigen simultaneous test (MAST) obtained from a domestic laboratory medicine facility and comprising 55 food allergens and 49 inhalant allergens from 368,156 individuals aged 1 to 89. By calculating the cross-sensitization ratio, the degree of cross-sensitization between each food allergen and inhalant allergen was determined. Further subgroup analysis was conducted to ascertain the cross-sensitization ratio between the four subgroups categorized by age. RESULTS: The median cross-sensitization ratio between food and inhalant allergens was 5.14, indicating a significant level of cross-sensitization. The cross-sensitization ratio was greatest among pollen allergens and plant-derived food allergens, followed by between some animal aeroallergens and meat/fish/dairy/poultry food allergens. The degree of overall cross-sensitization was least prominent in adolescents, greater in adults and children, and most pronounced in the elderly. CONCLUSION: Our findings reveal that various inhalant and dietary allergens have considerable cross-sensitivity, with the elderly having the highest degree of cross-sensitivity and adolescents the lowest.

Comparison of body size perception of young women in Korea and the United States.

Body size perception among young women in Asian and Western countries is believed to be quite different, however, there are no confirming studies. We analyzed the data from young women aged between 20 and 40 who participated in the National Health and Nutrition Examination Survey (2001-2018) of the United States (US) and Korea. US young women had higher rates of being overweight and obesity than Korean young women, and there was no significant change over 20 years. In both countries, the percentage of properly estimating one's own weight exceeded 70 percent and remained relatively steady. The percentage of overestimating one's own weight was only about 10 percent in Korea in 2001, but increased to 20 percent. In the case of the US, the percentage was about 15 percent in 2001-2002, but has since continued to decline. The percentage of underestimating one's own body weight was about 18 percent in Korea in 2001, but decreased to about 8 percent. In the case of the US, the percentage was very low at about 10 percent in 2001-2002, but gradually increased to about 18 percent in 2017-2018. In conclusion, young women in the US tend to underestimate their body size, and those in Korea tend to overestimate it.

The Role of Staphylococcus aureus in Patients with Chronic Sinusitis and Nasal Polyposis.

PURPOSE OF REVIEW: Staphylococcus aureus (S. aureus) is correlated with the development of persistent severe inflammatory disease of the upper airway including chronic rhinosinusitis with nasal polyps (CRSwNP). The presence of S. aureus is associated with atopic disease including allergic rhinitis and atopic dermatitis and is associated with poor outcomes. RECENT FINDINGS: Several different strains of S. aureus generate different toxins and gene products that can account for organism pathogenicity. S. aureus bacteria and its antigens shape the bacterial and fungal microbiome and the mucosal niche which generates host responses that can account for inflammation. The multiple disease phenotypes and molecular endotypes seen in CRSwNP can be characterized by T-helper cell environment within the inflammatory milieu, the presence of epithelial barrier dysfunction, aberrant eicosanoid metabolism, poor wound healing, and dysfunctional host-bacteria interactions which lead to recalcitrant disease and worse surgical outcomes. Understanding the pathomechanisms that S. aureus utilizes to promote nasal polyp formation, prolonged tissue inflammation, and bacterial dysbiosis are essential in our efforts to identify new therapeutic approaches to resolve this chronic inflammatory process.

Sinonasal quality of life outcomes following laser treatment of epistaxis related to hereditary hemorrhagic telangiectasia.

Hereditary hemorrhagic telangiectasia (HHT) is an inherited vascular disorder which manifests as recurrent, episodic, and potentially debilitating epistaxis. In this study, we aim to (1) characterize baseline sinonasal symptoms for HHT patients and to (2) analyze changes in sinonasal symptoms before and after laser surgical treatment for HHT. We performed a retrospective chart review of sinonasal outcome test-22 (SNOT-22) scores before and after one or more laser surgical treatments for HHT-related epistaxis between January 1, 2010 and December 1, 2015 at a tertiary academic medical center with an HHT Foundation-approved Center of Excellence. Preoperative and all subsequent postoperative SNOT-22 scores (short-term, <45 days and long-term, ≥45 days) were compared. Twenty consecutive HHT patients underwent 51 laser surgeries for recurrent epistaxis. Mean preoperative, short-term postoperative, and long-term postoperative SNOT-22 scores were 34.6 ± 5.4, 33.9 ± 5.5, and 18.8 ± 4.6, respectively. When analyzing subcategory scores, there was a significant improvement in the rhinologic domain from short-term to long-term postoperatively (13.5 vs. 7.3; p = 0.004), in the non-rhinologic otolaryngic domain from short-term to long-term postoperatively (2.8 vs. 1.7; p = 0.014), and in the psychological domain from preoperative and short-term postoperative to long-term postoperatively (12.2 and 10.0 vs. 6.0; p = 0.015 and 0.01, respectively). Following laser surgery for HHT-related epistaxis, patients' rhinologic symptoms worsened on the short run postoperatively but improved over time. The main benefit of laser treatment appears to be long-term improvement in psychological factors. This study once again underscores the important role of the otolaryngologist in managing sinonasal manifestations of HHT.

Arterial supply of the human soft palate.

PURPOSE: Palatal surgery for snoring or obstructive sleep apnea is commonly performed; however, the vascular anatomy of the soft palate is not well described. The purpose of this study was to evaluate the vascular anatomy of the soft palate. METHODS: This study was performed on 22 adult cadaveric heads. All specimens were prepared with vascular injections using red liquid silicone through the common carotid artery. The palate was then harvested and decolorized, and the vascular anatomy was studied. RESULTS: Of 22 specimens, 20 had sufficient uptake of the silicone dye. The anterior and posterior branches of the ascending palatine artery were the main feeding vessels of the soft palate; however, they were not always present simultaneously. The anterior branch alone was identified 25% of the time (5/20), while the posterior branch alone was found in 35% (7/20) of specimens. Both anterior and posterior branches were simultaneously present in 40% (8/20) of cases. Mean diameter of the anterior branch (0.73 ± 0.09 mm) was significantly greater than that of the posterior branch (0.48 ± 0.08 mm, p < 0.001). Mean vertical distance from the palatal arch to the posterior branch was 9.3 ± 2.4 mm. CONCLUSIONS: The soft palate is supplied by the anterior and posterior branches of the ascending palatine artery; however, the arteries were not always present simultaneously. In cases where the anterior branch is absent and the posterior branches terminate close to the uvula, injury to the primary blood supply to the palate might occur more frequently during surgery.

Using fixed anatomical landmarks to avoid medial rectus injury: a radiographic analysis in patients with and without Graves' disease.

BACKGROUND: Injury to the medial rectus (MR) is a potentially devastating complication of orbital and sinus surgery. Precise knowledge of the MR relative to the lamina papyracea (LP) is important during endoscopic surgery for both Graves' ophthalmopathy and inflammatory disease. The objective of this study is to determine the location of the MR in relation to easily identified and frequently encountered intranasal landmarks in patients with and without Graves' disease. METHODS: High-resolution computed tomography scans were analyzed in 100 controls and 63 patients with Graves' disease. The MR position was recorded relative to the maxillary sinus ostium (MSO), anterior ethmoid artery (AEA), and posterior ethmoid artery (PEA)/horizontal basal lamella (BL). Clinically relevant variables recorded at each level included the Keros stage, AEA position, MR height, and distance of the MR to orbital floor, skull base, and LP. RESULTS: The mean distances between the MR and LP were statistically different for both groups. Controls at the MSO, AEA, and PEA/BL were 2.92, 1.69, and 1.06mm; for Graves' patients measurements at these sites were 2.12, 1.20, and 0.029mm. When comparing the two groups, each of these distances were statistically significant (p<0.02). There was no difference in ethmoid cavity width (p>0.05) between controls (9.66mm) and Graves' patients (9.70mm). Sex, age, and skull base depth were not statistically significant factors. CONCLUSION: This study illustrates the position of the MR from the perspective of an endoscopic surgeon utilizing fixed intranasal landmarks. Knowledge of the position of MR is critical to safely perform decompression surgery and when operating adjacent to the LP during endoscopic surgery.

Nasal Floor Mucosa: New Donor Site for Mucous Membrane Grafts.

PURPOSE: Mucous membrane grafts are used for various indications in oculoplastics. The authors report the use of nasal floor mucosa as a new donor site for mucous membrane grafts. METHODS: Following adequate anesthesia and vasoconstriction, the nasal floor is visualized with a 30° endoscope. Next, the interior turbinate is medialized, and the nasolacrimal duct is identified and preserved. Anterior, posterior, medial, and lateral incisions are made through the nasal mucosa to the nasal bone. The mucosa is dissected off the nasal bone with a periosteal elevator. Nasal saline irrigation is used postoperatively to aid healing. Histologic analysis of the harvested graft and mucosa from the inferior and middle turbinates were analyzed histologically for the number of mucin-producing cells per high power field and compared. RESULTS: Nasal floor mucosa provides ample tissue for grafting with little donor site morbidity. The surgery is technically easy to learn and perform. There is less risk for blood loss compared with harvesting tissue from the turbinates and less postoperative discomfort compared with buccal mucosal grafts. The grafts have been used in 9 different patients for a variety of ocular indications. Histologically, the nasal floor mucosa contains statistically more mucin-secreting cells than other nasal site, which can be helpful especially in cases of ocular surface disease. In 1 case, biopsy of the grafted tissue at postoperative year 2 showed survival of the respiratory mucin-secreting cells under histologic examination. CONCLUSIONS: Nasal floor mucosa should be considered a donor site when a mucous membrane graft is needed. The surgery is safe, easy to perform, and has less morbidity than either a nasal turbinate graft or a buccal mucosal graft.

Role of Rhinopharyngoscopy in Diagnosis of Rhinopathies.

Rhinopathies, or diseases of the sinonasal cavity, are a heterogeneous group of disorders ranging from benign entities to malignant processes. Proper evaluation and treatment of rhinopathies are dependent on accurate visualization and characterization of the disease processes. Prior methods of evaluation of the sinonasal cavity were dependent largely on anterior rhinoscopy, which unfortunately provides poor visualization of the superior, posterior, and lateral extent of the sinonasal cavity. With the advent of high-definition flexible and rigid endoscopes, rhinopharyngoscopy has proven to be a critical component in the evaluation of the sinonasal cavity. Here, we discuss rhinopharyngoscopy with emphasis on technique and evaluation of common rhinopathies and future developments.

Empty nose syndrome.

Empty nose syndrome (ENS) is a rare, late complication of turbinate surgery. The most common clinical symptoms are paradoxical nasal obstruction, nasal dryness and crusting, and a persistent feeling of dyspnea. Little is known about the pathogenesis of ENS, though it is speculated that anatomical changes leading to alterations in local environment, disruption of mucosal cooling, and disruption of neurosensory mechanisms are strongly implicated. The diagnosis is clinical, though often difficult to make due to the poor correlation between subjective and objective findings. Medical therapies include mucosal humidification, irrigations, and emollients. Surgical therapy should be reserved for refractory cases and may involve turbinate reconstruction, most commonly using implantable biomaterials. Ultimately, prevention of this feared complication through turbinate-sparing techniques is essential.

Fungal and Bacterial Microbiome in Sinus Mucosa of Patients with and without Chronic Rhinosinusitis.

OBJECTIVES: Dysbiosis of the sinonasal microbiome has been implicated in the pathogenesis of chronic rhinosinusitis (CRS). However, the mycobiome remains largely understudied, and microbial alterations associated with specific CRS subtypes have yet to be delineated. The objective of this study is to investigate the fungal and bacterial microbiome of sinus mucosa in CRS patients with and without nasal polyposis (CRSwNP and CRSsNP) versus healthy controls. METHODS: Sinus mucosa was obtained from 92 patients (31 CRSsNP, 31 CRSwNP, and 30 controls) undergoing endoscopic sinus/skull base surgery. Data regarding demographics, Lund-MacKay scores, and histopathology were collected. Fungal and bacterial microbiome analysis was performed utilizing internal transcribed spacer amplicon and 16S rRNA sequencing. RESULTS: Beta diversity of the sinonasal mycobiome differed significantly between CRS and controls (p = 0.001) and between CRSwNP and controls (p = 0.049), but not between CRSwNP and CRSsNP (p = 0.32) nor between CRSsNP and controls (p = 0.06). With respect to the bacterial microbiome, significantly lower alpha diversity was observed between CRS and controls (p < 0.001), CRSwNP versus controls (p < 0.001), and CRSsNP versus controls (p < 0.001). Beta diversity was also significantly different at the genus level between CRSwNP and CRSsNP (p = 0.019), CRSwNP and controls (p = 0.002)), and CRSsNP and controls (p < 0.001). However, alpha and beta diversity did not differ significantly between CRS patients with/without eosinophils or correlate with Lund-MacKay scores. CONCLUSIONS: Differences in mycobiota diversity in CRS patients in comparison with controls suggest that alterations in the mycobiome may contribute to disease pathogenesis. Our findings also confirmed that diminished diversity among bacterial communities is associated with CRS and that significant differences are present in microbial composition between CRSwNP and CRSsNP.

Decreases in Rhinology Care Utilization by People with Cystic Fibrosis on Highly Effective Modulator Therapy.

BACKGROUND: Many people with cystic fibrosis (PwCF) have chronic rhinosinusitis (CRS). CRS requires additional management beyond that of pulmonary disease and leads to increased utilization of healthcare resources. Elexacaftor/tezacaftor/ivacaftor (ETI) is a highly effective modulator therapy that has been shown to improve CRS in PwCF. However, the impact of ETI on rhinologic healthcare utilization is understudied. OBJECTIVE: To compare rates of rhinologic healthcare utilization and procedures among PwCF prior to and after initiating ETI therapy. METHODS: A single-center, cohort study investigating adult PwCF was performed in January 2023. Demographics, clinical characteristics, and data related to CF treatment were retrospectively abstracted. Characteristics of the cohort were compared over 2 periods: the 12-months prior to ETI initiation and the 12-months after ETI initiation. Post-ETI data were linearly extrapolated if a subject had not yet completed the full 12 months of ETI. Paired t-testing, Wilcoxon signed rank testing, and regression analysis were performed. RESULTS: Of 126 PwCF, 98 (77.8%) were on ETI therapy and 35 (27.7%) were both on ETI and concurrently followed by the rhinology service (ETI-ENT). Rhinology clinic visits (P = .007) and frequency of obtaining nasal cultures (P = .046) decreased for the ETI-ENT cohort after initiating ETI treatment. There were no significant changes in the number of endoscopic sinus surgeries (P = .452) performed. Beyond ETI use, regression analysis did not identify any factors associated with changes in utilization. CONCLUSION: Aspects of rhinology healthcare utilization by PwCF decreased after initiation of ETI therapy. Additional studies are needed to determine rhinologic healthcare requirements for PwCF who remain on ETI for the long-term and to evaluate larger cohorts of PwCF on ETI.

Risk Factors Associated with Postoperative CSF Leak in Extrasellar Tumors.

Objective While postoperative cerebrospinal fluid (CSF) leak rates of pituitary tumors have been frequently studied, there are fewer studies examining postoperative CSF leak rates for extrasellar tumors. The purpose of this study was to identify risk factors for the development of postoperative CSF leak in patients undergoing endoscopic surgery for extrasellar tumors. Methods A retrospective chart review was done for patients who underwent endoscopic resection for extrasellar tumors between 2008 and 2020. Age, gender, tumor type, tumor location, tumor size, reconstruction technique, medical comorbidities, and other potential risk factors were identified. Data was analyzed to identify significant risk factors for development of postoperative CSF leak. Results There were 100 patients with extrasellar tumors who developed intraoperative CSF leaks. Seventeen patients (17%) developed postoperative CSF leaks. Leaks occurred at a median of 2 days following surgery (range 0-34 days). Clival tumors had a significantly higher incidence of postoperative leak than those in other sites ( p < 0.05). There were no significant differences in other locations, body mass index, tumor size, reconstruction technique, medical comorbidities, or other factors. There were nearly twice as many intraoperative grade III leaks in those who developed postoperative CSF leak, but this was not statistically significant ( p = 0.12). Conclusion Extrasellar tumors, particularly clival tumors, have a higher rate of postoperative CSF leak than pituitary tumors. Prophylactic lumbar drains can be considered for patients at high risk for developing postoperative CSF leak.

Comparison of patient-reported outcomes and clinical characteristics among patients with pituitary macroadenomas and giant adenomas.

KEY POINTS: Patients with giant adenomas are more likely to have tumor extension into the paranasal sinuses. Compared to macroadenomas, giant adenomas are not associated with worse preoperative SNOT-22 scores.

Predictive factors for decreased baseline quality of life in patients with sinonasal malignancies.

BACKGROUND: The impact of sinonasal malignancies (SNMs) on quality of life (QOL) at presentation is poorly understood. The Sinonasal Outcome Test (SNOT-22) and University of Washington Quality of Life (UWQOL) are validated QOL instruments with distinctive subdomains. This study aims to identify factors impacting pretreatment QOL in SNM patients to personalize multidisciplinary management and counseling. METHODS: Patients with previously untreated SNMs were prospectively enrolled (2015-2022) in a multicenter observational study. Baseline pretreatment QOL instruments (SNOT-22, UWQOL) were obtained along with demographics, comorbidities, histopathology/staging, tumor involvement, and symptoms. Multivariable regression models identified factors associated with reduced baseline QOL. RESULTS: Among 204 patients, presenting baseline QOL was significantly reduced. Multivariable regression showed worse total SNOT-22 QOL in patients with skull base erosion (p = 0.02). SNOT-rhinologic QOL was worse in women (p = 0.009), patients with epistaxis (p = 0.036), and industrial exposure (p = 0.005). SNOT extranasal QOL was worse in patients with industrial exposure (p = 0.016); worse SNOT ear/facial QOL if perineural invasion (PNI) (p = 0.027). Squamous cell carcinoma pathology (p = 0.037), palate involvement (p = 0.012), and pain (p = 0.017) were associated with worse SNOT sleep QOL scores. SNOT psychological subdomain scores were significantly worse in patients with palate lesions (p = 0.022), skull base erosion (p = 0.025), and T1 staging (p = 0.023). Low QOL was more likely in the presence of PNI on UW health (p = 0.019) and orbital erosion on UW overall (p = 0.03). UW social QOL was worse if palatal involvement (p = 0.023) or PNI (p = 0.005). CONCLUSIONS: Our findings demonstrate a negative impact on baseline QOL in patients with SNMs and suggest sex-specific and symptom-related lower QOL scores, with minimal histopathology association. Anatomical tumor involvement may be more reflective of QOL than T-staging, as orbital and skull base erosion, PNI, and palate lesions are significantly associated with reduced baseline QOL.

Factors that predict pursuing sinus surgery in the era of highly effective modulator therapy.

BACKGROUND: Comorbid chronic rhinosinusitis (CRS) remains unresolved for many people with cystic fibrosis (PwCF). While highly effective modulator therapy improves quality-of-life and symptom severity, the impact of this intervention and other factors associated with pursuing endoscopic sinus surgery (ESS) remains understudied. METHODS: Adult PwCF + CRS were enrolled into a prospective, observational, multi-institutional study. Participants completed validated outcome measures to evaluate respiratory symptom severity, depression, headache, and sleep quality, as well as nasal endoscopy, sinus computed tomography (CT), and olfactory testing. Bivariate comparisons and regression modeling evaluated treatment cofactors, disease characteristics, and outcome measures associated with pursuing ESS. RESULTS: Sixty PwCF were analyzed, including 24 (40%) who elected ESS. Pursuing ESS was associated with worse SinoNasal Outcome Test (SNOT-22) total, rhinologic, psychological, and sleep dysfunction domain scores; worse Patient Health Questionnaire-9-Revised depression scores; worse Pittsburgh Sleep Quality Index total scores; worse weight, role, emotion, and eating domain scores on the Cystic Fibrosis Questionnaire-Revised; more severe disease on nasal endoscopy; and lack of modulator therapy (all p < 0.050). Multivariable regression identified that worse SNOT-22 total score was associated with electing ESS (odds ratio [OR] 1.09, 95% confidence interval [CI] 1.02-1.16, p = 0.015) and elexacaftor/tezacaftor/ivacaftor (ETI) treatment (OR 0.04, 95% CI 0.004-0.34, p = 0.004) was associated with pursing medical therapy. CONCLUSIONS: Worse sinonasal symptom burden, lack of ETI treatment, sleep quality, depression, and nasal endoscopy scores were associated with electing ESS, while lung disease severity and sinus CT scores were not. ETI use was associated with lower odds of pursuing ESS independent of sinonasal symptom burden.

Determining the minimal clinically important difference for the questionnaire of olfactory disorders in people with cystic fibrosis and factors associated with improvement after highly effective modulator therapy.

INTRODUCTION: Olfactory dysfunction (OD) is common among people with cystic fibrosis (PwCF). The Questionnaire of Olfactory Disorders (QOD) is a validated instrument that evaluates olfactory-specific quality-of-life. The QOD minimal clinically important difference (MCID) and factors associated with olfactory improvement after elexacaftor/tezacaftor/ivacaftor have not been determined for PwCF. METHODS: Prospective observational data were pooled from three studies that enrolled adult PwCF with chronic rhinosinusitis (CRS). QOD scores and disease characteristics were assessed. To evaluate internal consistency and calculate the QOD MCID, Cronbach's alpha and four distribution-based methods were employed. For participants who enrolled prior to elexacaftor/tezacaftor/ivacaftor, QOD scores were obtained at baseline and after elexacaftor/tezacaftor/ivacaftor initiation. Multivariable regression was used to identify factors associated with QOD improvement. RESULTS: Of 129 PwCF included, 65 had QOD scores before and 3-6 months after starting elexacaftor/tezacaftor/ivacaftor. Mean baseline QOD score was 6.5 ± 7.9. Mean Cronbach's alpha was ≥0.85. The MCID estimates were as follows: Cohen's effect size = 1.6, standard error of measurement = 2.5, ½ baseline standard deviation = 4.0, and minimal detectable change = 6.9. Mean MCID was 3.7. Of those with pre/post elexacaftor/tezacaftor/ivacaftor QOD scores, the mean change in QOD was -1.3 ± 5.4. After elexacaftor/tezacaftor/ivacaftor, QOD improvement surpassed the MCID in 22% of participants (14/65). Worse baseline QOD scores and nasal polyps were associated with improved QOD scores after elexacaftor/tezacaftor/ivacaftor (both p < 0.04). CONCLUSION: The QOD MCID in PwCF was estimated to be 3.7. Elexacaftor/tezacaftor/ivacaftor led to qualitative but not clinically meaningful improvements in QOD score for most PwCF; PwCF with worse baseline QOD scores and nasal polyps improved in a clinically significant manner.

University of Washington Quality of Life subdomain outcomes after treatment of sinonasal malignancy: A prospective, multicenter study.

PURPOSE: Sinonasal malignancies (SNMs) adversely impact patients' quality of life (QOL) and are frequently identified at an advanced stage. Because these tumors are rare, there are few studies that examine the specific QOL areas that are impacted. This knowledge would help improve the care of these patients. METHODS: In this prospective, multi-institutional study, 273 patients with SNMs who underwent definitive treatment with curative intent were evaluated. We used the University of Washington Quality of Life (UWQOL) instrument over 5 years from diagnosis to identify demographic, treatment, and disease-related factors that influence each of the 12 UWQOL subdomains from baseline to 5 -years post-treatment. RESULTS: Multivariate models found endoscopic resection predicted improved pain (vs. nonsurgical treatment CI 2.4, 19.4, p = 0.01) and appearance versus open (CI 27.0, 35.0, p < 0.001) or combined (CI 10.4, 17.1, p < 0.001). Pterygopalatine fossa involvement predicted worse swallow (CI -10.8, -2.4, p = 0.01) and pain (CI -17.0, -4.0, p < 0.001). Neck dissection predicted worse swallow (CI -14.8, -2.8, p < 0.001), taste (CI -31.7, -1.5, p = 0.02), and salivary symptoms (CI -28.4, -8.6, p < 0.001). Maxillary involvement predicted worse chewing (CI 9.8, 33.2; p < 0.001) and speech (CI -21.8, -5.4, p < 0.001) relative to other sites. Advanced T stage predicted worse anxiety (CI -13.0, -2.0, p = 0.03). CONCLUSIONS: Surgical approach, management of cervical disease, tumor extent, and site of involvement impacted variable UWQOL symptom areas. Endoscopic resection predicted better pain, appearance, and chewing compared with open. These results may aid in counseling patients regarding potential QOL expectations in their SNM treatment and recovery course.

Impact of sociodemographic status and sex on chronic rhinosinusitis and olfaction in people with cystic fibrosis.

BACKGROUND: Sociodemographic status (SDS) including race/ethnicity and socioeconomic status as approximated by education, income, and insurance status impact pulmonary disease in people with cystic fibrosis (PwCF). The relationship between SDS and chronic rhinosinusitis (CRS) remains understudied. METHODS: In a prospective, multi-institutional study, adult PwCF completed the 22-Question SinoNasal Outcome Test (SNOT-22), Smell Identification Test (SIT), Questionnaire of Olfactory Disorder Negative Statements (QOD-NS), and Cystic Fibrosis Questionnaire-Revised (CFQ-R). Lund-Kennedy scores, sinus computed tomography, and clinical data were collected. Data were analyzed across race/ethnicity, sex, and socioeconomic factors using multivariate regression. RESULTS: Seventy-three PwCF participated with a mean age of 34.7 ± 10.9 years and 49 (67.1%) were female. Linear regression identified that elexacaftor/tezacaftor/ivacaftor (ETI) use (ß = â€’4.09, 95% confidence interval [CI] [‒6.08, ‒2.11], p < 0.001), female sex (ß = â€’2.14, 95% CI [‒4.11, ‒0.17], p = 0.034), and increasing age (ß = â€’0.14, 95% CI [‒0.22, ‒0.05], p = 0.003) were associated with lower/better endoscopy scores. Private health insurance (ß = 17.76, 95% CI [5.20, 30.32], p = 0.006) and >16 educational years (ß = 13.50, 95% CI [2.21, 24.80], p = 0.020) were associated with higher baseline percent predicted forced expiratory volume in one second (ppFEV1). Medicaid/Medicare insurance was associated with worse endoscopy scores, CFQ-R respiratory scores, and ppFEV1 (all p < 0.017), and Hispanic/Latino ethnicity was associated with worse SNOT-22 scores (p = 0.047), prior to adjustment for other cofactors. No other SDS factors were associated with SNOT-22, QOD-NS, or SIT scores. CONCLUSIONS: Differences in objective measures of CRS severity exist among PwCF related to sex, age, and ETI use. Variant status and race did not influence patient-reported CRS severity measures or olfaction in this study. Understanding how these factors impact response to treatment may improve care disparities among PwCF. CLINICAL TRIALS: NCT04469439.

Patient perspectives on chronic rhinosinusitis in cystic fibrosis: Symptom prioritization in the era of highly effective modulator therapy.

BACKGROUND: Chronic rhinosinusitis (CRS) is common in people with cystic fibrosis (PwCF). Rhinologic symptom prioritization and areas that influence CRS treatment choices, including pursuing endoscopic sinus surgery (ESS), remain understudied. METHODS: Adult PwCF + CRS were enrolled at eight centers into a prospective, observational study (2019-2023). Participants were administered the 22-SinoNasal Outcome Test (SNOT-22) survey and a modified SNOT-22 instrument examining symptom importance. We determined importance rankings for individual symptoms and SNOT-22 symptom importance subdomains in two sets of subgroups-those pursuing ESS versus continuing medical management (CMT), and those on elexacaftor/tezacaftor/ivacaftor (ETI) versus not on ETI. RESULTS: Among 69 participants, the highest priorities were nasal congestion (n = 48, 69.6% important), post-nasal discharge (32, 46.4%), facial pain (29, 43.3%), waking up tired (27, 39.1%), and fatigue (26, 37.7%). Those electing surgery (n = 23) prioritized sleep and psychological dysfunction symptoms compared to those pursuing CMT (n = 49) (sleep median score = 19.0 [interquartile range: 12.0, 25.0] vs. 4.5 [0.0, 12.8]; p < 0.0001; psychological = 17.0 [7.0, 26.0] vs. 7.0 [0.0, 15.8]; p = 0.002). ETI users had comparable SNOT-22 total symptom importance scores to non-ETI users (p = 0.14). Non-ETI users (n = 34) showed a trend toward prioritizing sleep symptoms compared to ETI users (n = 35) (13.0 [2.8, 22.3] vs. 6.0 [2.0, 17.0]; p = 0.055). CONCLUSIONS: Nasal congestion and post-nasal discharge were top priorities reported by PwCF + CRS. Those electing surgery prioritized sleep and psychological symptoms, highlighting their importance in pre-operative discussions. Non-ETI users' prioritization of sleep improvement may highlight their unique disease impact and therapeutic needs; however, additional investigation is required.
