OBJECTIVES: There is growing interest in assessing patient quality of life (QOL) following treatment of sinonasal tumors, including inverted papilloma (IP). We aimed to elucidate the natural history of postoperative QOL outcomes in IP patients treated with surgery. METHODS: Cases of sinonasal IP treated surgically at 4 tertiary academic rhinology centers were retrospectively reviewed. SNOT-22 scores were used to evaluate QOL preoperatively and postoperatively (1, 3, 6, 12 months). Repeated-measures ANOVA assessed for differences in mean scores over time. Linear regression identified factors associated with QOL longitudinally. RESULTS: 373 patients were analyzed. Mean preoperative SNOT-22 score was 20.6 ± 20.4, which decreased to 16.3 ± 18.8 (p = 0.041) and 11.8 ± 15.0 (p 0.05). When analyzed by SNOT-22 subdomains, nasal, sleep, and otologic/facial subdomain scores (all p 0.05). CONCLUSIONS: QOL outcomes related to IP resection are largely driven by nasal, sleep, and otologic/facial subdomains, though patients appear to experience enduring improvement as early as 3 months postoperatively. Recurrent disease is a major driver of negative QOL. LEVEL OF EVIDENCE: 4 Laryngoscope, 135:579-585, 2025.

Romano, Richard M. and Palmer, James C.
- Abstract
It is generally accepted that the nation's community colleges are underfunded, especially given the job that society expects of them. Accordingly, practitioners and scholars have long argued for new revenue sources and funding models. This essay briefly explains one such alternative model, namely funding adequacy. This concept has a long history at the K-12 level and holds potential for application in community colleges.

Objective Surgical resection is widely accepted as a critical component for definitive treatment of sinonasal mucosal melanoma. Systemic immunotherapy, including multiple newer agents, has been used to treat metastatic or unresectable disease. In this study, we examine its efficacy in locoregional control when used in conjunction with surgical resection for primary mucosal lesions. Design Present study is a retrospective review of all patients at a tertiary academic medical center with primary sinonasal mucosal melanoma and distant metastatic disease. Results A total of four patients were identified. In all cases, patients were treated with a combination of surgical resection of the primary tumor and systemic immunotherapy. Three patients were initially treated with surgery at the primary site followed by immunotherapy for distant metastases. Response to immunotherapy at the sites of primary and metastatic disease was seen in two patients. All four patients developed progression or recurrence at the primary site following initiation of immunotherapy for which they underwent surgical resection. One patient remains in follow-up without evidence of disease 20 months after initial treatment; three succumbed to the disease at 135, 37, and 16 months after initial treatment. Conclusion Surgical resection for local control plays a critically important role in the treatment of sinonasal mucosal melanoma regardless of the presence of metastases and whether immunotherapy will be given. This case series suggests that, though immunotherapy may demonstrate efficacy in managing distant disease, surgery should remain the first-line treatment for the primary site.

Objective Radiation therapy represents an uncommon but important component of treatment plans for some pituitary adenomas (PAs). Although radiation therapy has been used to treat pituitary adenomas for over a century, general trends in the usage of radiation therapy for this purpose have not been reviewed. Additionally, there are few large studies evaluating how radiation therapy is used for the treatment of these benign tumors. Investigating these trends and identifying any variations in radiation therapy utilization would help to better inform treatment decisions and improve patient outcomes. Design Present study is a retrospective analysis of cases using the National Cancer Database. Setting The research was organized at a tertiary academic medical center. Participants Patients were diagnosed with pituitary adenoma between 2004 and 2014 within the National Cancer Database (NCDB). Methods Temporal trends in the usage of radiation therapy to treat pituitary adenoma were analyzed through a retrospective analysis of 77,142 pituitary adenoma cases from the NCDB between 2004 and 2014. Univariate and multivariate analyses were to examine the relationship between patient, tumor, and treatment factors, and the incorporation of radiation therapy into the treatment of pituitary adenomas. We adjusted for potential confounders such as age, sex, race, comorbidity score, facility type, and year of diagnosis. Results A total of 77,142 patients met inclusion criteria. Inclusion of radiation therapy in pituitary adenoma treatment was 8.0% in 2004 and steadily declined to a low of 3.1% in 2014. Overall, patients were less likely to receive radiation for their pituitary adenoma over time ( p

JNJ-42165279 is a selective inhibitor of fatty acid amide hydrolase (FAAH), the enzyme responsible for the degradation of fatty acid amides (FAA) including anandamide (AEA), palmitoylethanolamide (PEA), and N-oleoylethanolamide (OEA). We assessed the efficacy, safety, tolerability, pharmacokinetics, and pharmacodynamics of treatment with JNJ-42165279 in subjects with social anxiety disorder (SAD). This was a multicenter, double-blind, placebo-controlled study randomizing subjects to 12 weeks of treatment with either JNJ-42165279 (25 mg daily) or placebo (PBO). The primary endpoint was the change in the Liebowitz Social Anxiety Scale (LSAS) total score from baseline to end of study. Secondary endpoints included the Hamilton Anxiety Scale (HAM-A), Hamilton Depression Rating Scale (HDRS17), and the Clinical Global Impression-Improvement (CGI-I). Samples were collected for plasma concentration of AEA, PEA, OEA, and JNJ-42165279. A total of 149 subjects were enrolled with a mean baseline LSAS total score of 102.6 (SD 16.84). The mean change from baseline (SD) in LSAS total score at week 12 was numerically greater for JNJ-42165279: -29.4 (27.47) compared to PBO: -22.4 (23.57) but not significant. The percentage of subjects with ≥30% improvement from baseline in the LSAS total score was significantly higher for JNJ-42165279 (42.4%) compared to PBO (23.6%) (p value = 0.04). The percentage of subjects with a CGI-I score of much or very much improved was also significantly higher for JNJ-42165279 (44.1%) than for PBO (23.6%) (p value = 0.02). The drug was well tolerated. JNJ-42165279 appears to elicit an anxiolytic effect in subjects with SAD although trough concentrations with 25 mg once daily appeared to be insufficient to completely inhibit FAAH activity which may have led to suboptimal efficacy. ClinicalTrials.gov Identifier: NCT02432703.

We report a comprehensive proteogenomics analysis, including whole-genome sequencing, RNA sequencing, and proteomics and phosphoproteomics profiling, of 218 tumors across 7 histological types of childhood brain cancer: low-grade glioma (n = 93), ependymoma (32), high-grade glioma (25), medulloblastoma (22), ganglioglioma (18), craniopharyngioma (16), and atypical teratoid rhabdoid tumor (12). Proteomics data identify common biological themes that span histological boundaries, suggesting that treatments used for one histological type may be applied effectively to other tumors sharing similar proteomics features. Immune landscape characterization reveals diverse tumor microenvironments across and within diagnoses. Proteomics data further reveal functional effects of somatic mutations and copy number variations (CNVs) not evident in transcriptomics data. Kinase-substrate association and co-expression network analysis identify important biological mechanisms of tumorigenesis. This is the first large-scale proteogenomics analysis across traditional histological boundaries to uncover foundational pediatric brain tumor biology and inform rational treatment selection.

Background Sinonasal adenocarcinoma (SNAC) is a rare malignancy arising from mucus-secreting glandular tissue. Limited large-scale studies are available due to its rarity. We evaluated SNAC in the National Cancer Database (NCDB), a source that affords multi-institutional, population studies of rare cancers and their outcomes. Methods The NCDB was queried for adenocarcinoma in the sinonasal tract. Multivariate analyses were performed to evaluate for factors contributing to overall survival (OS). Results A total of 553 patients were identified. The cohort was composed of 59.3% males. The nasal cavity was the most common primary site, representing 44.1% of cases. About 5.7% of patients presented with nodal disease, while 3.3% had distant metastases. About 40.6% of cases presented with stage IV disease. About 73.5% of patients underwent surgery, 54.2% received radiation therapy, and 27.7% had chemotherapy. Median OS was 71.7 months, while OS at 1, 2, and 5 years was 82, 73.0, and 52%, respectively. On multivariate analysis, advanced age (hazard ratio [HR]: 1.04; 95% confidence interval [CI]: 1.02-1.05), Charlson-Deyo score of 1 (HR: 1.99; 95% CI: 1.20-3.30), advanced tumor grade (HR: 2.73; 95% CI: 1.39-5.34), and advanced tumor stage (HR: 2.71; 95% CI: 1.33-5.50) were associated with worse OS, whereas surgery (HR: 0.34; 95% CI: 0.20-0.60) and radiation therapy (HR: 0.55; 95% CI: 0.33-0.91), but not chemotherapy (HR: 1.16; 95% CI: 0.66-2.05), predicted improved OS. Conclusions SNAC is a rare malignancy with 5-year survival approximating 50%. Surgery and radiation therapy, but not chemotherapy, are associated with improved survival, and likely play a critical role in the interdisciplinary management of SNAC.

Objectives A persistent craniopharyngeal canal (CPC) is a rare embryologic remnant that presents as a well-corticated defect of the midline sphenoid body extending from the sellar floor to the nasopharynx. Our case series aims to describe three unique presentations of this congenital anomaly and their subsequent management. Design Retrospective review. Setting Tertiary academic medical center. Participants Patients who underwent endoscopic transnasal surgical repair of a CPC lesion. Main Outcome Measures Resolution of symptoms and surgical outcomes. Results A total of three patients were identified. The clinical presentation varied, however, all cases prompted further imaging which demonstrated a persistent CPC and associated pathologic lesion. The presentation of a persistent CPC with nasal obstruction and subsequent iatrogenic cerebrospinal fluid leak as in Case 1 demonstrates the importance of imaging in this work-up. Cases 2 and 3 in the series were representative of the larger subset of patients in the literature who present with the defect incidentally but still warrant surgical management. Nonetheless, a standard approach to diagnosis with preoperative imaging and subsequent transnasal endoscopic repair of the skull base defect was undertaken. Conclusion The persistent CPC is a rare congenital anomaly associated with diverse pathology and careful review of preoperative radiology is critical to the management. When warranted, subsequent surgical repair and reconstruction is associated with excellent postoperative outcomes.

Introduction Olfactory groove meningiomas (OGMs) are often associated with loss of smell following resection. Loss of smell has a measurable impact on quality of life. Smell preservation has been previously described in open approaches for early stage or unilateral OGMs. Evidence of smell preservation in endoscopic approaches is lacking. Design A multi-institutional retrospective review was performed on consecutive patients who underwent unilateral endoscopic endonasal resection of OGM. A gross total resection was achieved with preservation of the contralateral olfactory cleft and bulb. Olfactory function was assessed with a six-point olfactory symptom score and the Sniffin Sticks 12-item smell identification test (SS-12). Contralateral olfactory bulb volume was measured on postoperative magnetic resonance imaging. Results Four patients (age 42.0 ± 7.5, 75% female) were assessed. Olfactory function was assessed at 21.8 ± 5.6 months following surgery. All patients reported some degree of smell preservation (75% described a slight/mild impairment in smell or better). Olfactory identification was preserved with an SS-12 score of 9 ± 1.4 (anosmia defined as ≤6). The olfactory bulb volume was calculated to be 47.4 ± 15.9 mm 3 (normal >40 mm 3 ). Conclusion Smell preservation is possible following unilateral endoscopic endonasal resection of carefully selected OGM.

Objectives Pituitary carcinoma is a rare entity with fewer than 200 total cases reported in the English literature. Analysis of the population-level data from the National Cancer Database (NCDB) affords the opportunity to study this poorly understood tumor type. Methods The NCDB was queried for site, histology, and metastasis codes corresponding to pituitary carcinoma. Statistical analyses were performed to determine factors associated with overall survival (OS). Results A total of 92 patients with pituitary carcinoma met inclusion criteria. The 1 and 5 years of OS for all patients was 93.3% (95% confidence interval [CI]: 88.2-98.6%) and 80.0% (95% CI: 71.6-89.4%), respectively. Patients with invasive primary tumor behavior had 1 and 5 years of OS of 69.2% (95% CI: 48.2-99.5%) and 52.7% (95% CI: 31.2-89.2%), respectively. Multivariate analysis demonstrated that compared with benign primary behavior, invasive behavior had increased all-cause mortality (hazard ratio [HR], 1,296, 95% CI: 15.1- > 2,000). Surgery without adjuvant radiation or chemotherapy was the most common therapy (48.9%), followed by no treatment (40.2%). Compared with surgery alone, no treatment had worse OS (HR, 11.83, 95% CI: 1.41-99.56). Increasing age and female sex were both associated with increased mortality. Conclusions The most common treatment for pituitary carcinoma is surgery alone followed by no surgery. Surgery alone has significantly better OS compared with no treatment. The efficacy of radiation, chemotherapy, and neurohormonal treatments needs to be examined with prospective studies.

Analysis of the population-level data from the National Cancer Database (NCDB) affords the opportunity to study this poorly understood tumor type. Methods The NCDB was queried for site, histology, and metastasis codes corresponding to pituitary carcinoma. Statistical analyses were performed to determine factors associated with overall survival (OS). Results A total of 92 patients with pituitary carcinoma met inclusion criteria. The 1 and 5 years of OS for all patients was 93.3% (95% confidence interval [CI]: 88.2-98.6%) and 80.0% (95% CI: 71.6-89.4%), respectively. Patients with invasive primary tumor behavior had 1 and 5 years of OS of 69.2% (95% CI: 48.2-99.5%) and 52.7% (95% CI: 31.2-89.2%), respectively. Multivariate analysis demonstrated that compared with benign primary behavior, invasive behavior had increased all-cause mortality (hazard ratio [HR], 1,296, 95% CI: 15.1- > 2,000). Surgery without adjuvant radiation or chemotherapy was the most common therapy (48.9%), followed by no treatment (40.2%). Compared with surgery alone, no treatment had worse OS (HR, 11.83, 95% CI: 1.41-99.56). Increasing age and female sex were both associated with increased mortality. Conclusions The most common treatment for pituitary carcinoma is surgery alone followed by no surgery. Surgery alone has significantly better OS compared with no treatment. The efficacy of radiation, chemotherapy, and neurohormonal treatments needs to be examined with prospective studies.

BACKGROUND: Solitary chemosensory cells (SCCs) are rare epithelial cells enriched in nasal polyps and are the primary source of interleukin-25 (IL-25), an innate cytokine eliciting T-helper 2 (Th2) immune response. Although it is proposed that SCCs are stimulated by antigens released by upper airway pathogens, the exogenous triggers of human SCCs remain elusive. We studied patients with noninvasive fungal rhinosinusitis to determine whether extracts of Aspergillus fumigatus and Alternaria alternata stimulate SCC proliferation as an early event in type 2 inflammation. METHODS: Multicolor flow cytometry, immunofluorescence, and enzyme-linked immunoassay were used to interrogate mucosa from patients with mycetomas and allergic fungal rhinosinusitis (AFRS) for SCCs and IL-25. Primary sinonasal epithelial cells from AFRS patients and noninflamed inferior turbinates were stimulated with fungal extracts for 72 hours, and SCC population frequency as well as mitotic activity were quantified using flow cytometry. RESULTS: SCCs producing IL-25 are enriched in inflamed mucosa compared with intrapatient noninflamed control tissue (38.6% vs 6.5%, p = 0.029). In cultured sinonasal epithelial cells from AFRS nasal polyps, Aspergillus fumigatus and Alternaria alternata stimulated higher SCC frequency compared with controls (27.4% vs 10.6%, p = 0.002; 18.1% vs 10.6%, p = 0.046), which led to increased IL-25 secretion in culture media (75.5 vs 3.3 pg/mL, p < 0.001; 32.3 vs 3.3 pg/mL, p = 0.007). Ki-67 expression was higher in SCCs grown in fungal stimulation conditions compared with controls. CONCLUSION: Although fungal antigens are known to potentiate immune response through innate cytokines, including IL-25, the early expansion of SCCs in the presence of fungus has not been described. This early event in the pathogenesis of noninvasive fungal rhinosinusitis may represent a target for intervention.

BACKGROUND: Broncho-Vaxom® (OM-85 BV) is an extract of infectious respiratory bacteria that is used as an immunostimulant outside of the United States for the prevention and treatment of bronchitis and rhinosinusitis. Prior studies have shown that use of OM-85 BV is associated with reduction in frequency of respiratory infection and decreased duration of antibiotic usage. However, the effects of OM-85 BV on respiratory mucosal innate immunity are unknown. METHODS: Human sinonasal epithelial cells were grown at an air-liquid interface (ALI). Ciliary beat frequency (CBF) and nitric oxide (NO) production in response to stimulation with OM-85 BV was measured in vitro. Pharmacologic inhibitors of bitter taste receptor (T2R) signaling were used to determine if this pathway was taste-receptor-mediated.

Background: To reduce recurrence rates of inverted papilloma (IP), some have argued for the use of intraoperative frozen margins; results remain mixed and studies critically lack lengthy surveillance periods. Objective: We aim to elucidate the impact of prolonged surveillance and intraoperative frozen margins on IP recurrence. Methods: This is a retrospective analysis of patients who underwent resection of IP at a tertiary care center over a 10-year period from 2008 to 2018 followed by subsequent surveillance. Patient demographics, tumor and operative characteristics, and recurrences were analyzed. Results: Our analysis includes 199 patients, with 37 recurrences and an average recurrence time of 44.4 months; 57% of patients received intraoperative frozen sections and recurrence rates were similar between those who received frozen sections and those who did not (20.1% vs 15.5%, P =.36). Patients with recurrences within 5 years of surgery were more likely to have received frozen sections than those with recurrences beyond 5 years (P <.01). There was no difference in surgical approach or extent of disease in those who received frozen margins. Patients that received frozen sections were more likely to have multiple sites of attachment (56.5% vs 38.1%, P =.01) and persistent disease following a previous resection at an outside institution (67.0% vs 44.0%, P =.001). Conclusion: Our average time to recurrence was 44.4 months, significantly longer than surveillance times reported in the literature, indicating that longer periods of surveillance are necessary to capture late recurrences. Our analysis is the first and largest American cohort to look at IP resection in a standardized fashion and find that recurrence rates are similar between patients receiving frozen sections or not.

The article in the Journal of Neurological Surgery discusses pituitary apoplexy (PA) precipitated by non-cranial surgeries, a rare condition caused by sudden hemorrhage or infarction within the pituitary gland. The study reports on a 6-year institutional experience of risk factors associated with PA following non-cranial surgical procedures, highlighting factors such as significant fluctuations in intraoperative blood pressure, preexisting hypertension, and the presence of pituitary macroadenomas exceeding 2 cm in diameter. The findings suggest that risk stratification based on adenoma size and past medical history, particularly hypertension, may be helpful in identifying patients at risk for PA.

Background: Viral infections have long been implicated in the development of chronic rhinosinusitis with nasal polyps (CRSwNP). Given widespread exposure to the common cold coronavirus 229E (HCoV229E), we sought to investigate how HCoV-229E is cleared and stimulates interferon pathways in air–liquid interface (ALI) cultures from patients with CRSwNP. Objective: The objective of this study was to identify whether viral clearance and ISG expression is different in ALI cultures from donors with CRSwNP compared with controls. Methods: Plaque assays were used to quantify infectious virus released by infected air–liquid interface (ALI) cultures derived from patients with CRSwNP compared to patients without CRS (controls). Additionally, mock and induced levels of Interferon Stimulated Genes (ISGs) mRNA following HCoV-229E infection were quantified by RT-qPCR. Results: Quantification of infectious virus by plaque assay reveals that CRSwNP ALI cultures were equally susceptible to HCoV-229E infection, and surprisingly viral titers dropped significantly faster than in the control ALI cultures. We further demonstrate that this accelerated viral clearance correlates with increased mRNA expression of at least 4 ISGs following viral infection in the CRSwNP ALIs compared to the control ALIs. Conclusion: This study paradoxically demonstrates that ALI cultures from patients with CRSwNP are more efficient at clearing the common cold HCoV-229E virus compared to controls. We also demonstrate significantly increased ISG mRNA expression following HCoV-229E infection in CRSwNP. These findings call for further investigation into the effect of unimpaired interferon signaling on the type 2 inflammatory environment in patients with CRSwNP. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Empty nose syndrome (ENS) is a poorly understood, debilitating condition affecting a minority of patients who underwent nasal airway surgery, most commonly following inferior turbinate surgery. Few publications have demonstrated middle turbinate resection (MTR) causing ENS, but MTR is still considered a potential cause of ENS. The Empty Nose Syndrome 6‐item Questionnaire (ENS6Q) is validated for ENS diagnosis, with ENS6Q ≥ 11 considered highly suggestive of ENS. The purpose of this multicenter study was to determine the incidence of patients with ENS6Q ≥ 11 following subtotal MTR during endoscopic sinus surgery (ESS) for chronic rhinosinusitis with nasal polyps (CRSwNP) by comparing preoperative and postoperative ENS6Q scores. Methods: A multi‐institutional prospective cohort study (8 US institutions) was conducted on patients who underwent bilateral subtotal MTR during ESS for CRSwNP. Preoperative and postoperative ENS6Q scores were compared after at least 12 months of postoperative follow‐up. Results: Of 110 patients, mean age was 51.6 years and 59.1% were male. Mean follow‐up was 14.5 ± 2.5 months (range 12.1–22.3 months). Mean preoperative and postoperative ENS6Q were 7.7 and 2.2, respectively, demonstrating a mean 5.5 point decrease postoperatively (p < 0.0001). At final follow‐up, no patient had an ENS6Q ≥ 11. Of note, 20% of patients had preoperative ENS6Q scores ≥11, but all decreased to <11 postoperatively. Conclusions: Based on prospective multicenter data over 1–2 years postoperatively, subtotal MTR for CRSwNP never led to ENS6Q scores ≥11, and patients experienced significant decreases in ENS6Q postoperatively. Subtotal MTR during ESS for CRSwNP was, therefore, unlikely to cause ENS even with long‐term follow‐up. Level of Evidence: 4 Laryngoscope, 135:59–65, 2025 [ABSTRACT FROM AUTHOR]

PurposeTo report a case of metastatic cutaneous melanoma presenting with choroidal metastasis simulating primary uveal melanoma.DesignCase report.MethodPresentation of clinical, radiographic, histopathologic, and tumor genetic findings in a patient with cutaneous melanoma with choroidal metastasis.ResultsA 50-year-old man with a remote history of stage 1A cutaneous melanoma presented with eye pain, peripheral vision loss, floaters, red eye, and choroidal mass that was originally diagnosed as a primary uveal melanoma at an outside institution; however, subsequent imaging and clinical evaluation demonstrated that this choroidal mass was the first manifestation of widely metastatic cutaneous melanoma (liver, pancreas, lung, bone, brain, and orbit lesions). Histopathologic analysis of the tumor after enucleation was consistent with cutaneous melanoma, and tumor genetic testing was positive for BRAF V600E mutation, confirming the choroidal lesion to be a cutaneous melanoma metastasis rather than a primary choroidal melanoma.ConclusionsMetastatic cutaneous melanoma to the orbit or globe occurs rarely. Tumor genetic testing may help differentiate metastatic cutaneous melanoma from primary uveal melanoma in cases where the diagnosis is uncertain, and can also inform therapy and prognostic counseling.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is commonly characterized by type-2 inflammation. It is established that group-2 innate lymphoid cells (ILC2s) are a subset of immune cells important in orchestrating mucosal type-2 response. IL-25 is an epithelial-derived cytokine that is a critical activator of ILC2s. Recent evidence demonstrates that specialized taster epithelial cells, such as solitary chemosensory cells (SCCs), may be producers of IL-25. To elucidate the relationship between SCCs and ILC2s in CRSwNP, we sought to quantify ILC2s and SCCs to determine if these cell types are enriched in nasal polyps compared to healthy sinonasal mucosa. We quantified SCCs and ILC2s using multicolor flow cytometry in nasal polyps and non-inflamed turbinate mucosa from seven patients and investigated the role of IL-13 and dexamethasone on SCC frequency using tissue explants of nasal polyps and turbinate mucosa. SCCs were found to be the primary source of IL-25. Nasal polyps demonstrated higher populations of SCCs (33.0% vs 5.6%, p < 0.001) and ILC2s (2.40% vs 0.19%, p = 0.008) compared to patient-matched nonpolypoid turbinates. In cultured polyp explants, exogenous IL-13 increased the proportion of epithelial SCCs (40.2% IL-13 condition vs 28.9% untreated, p = 0.012), and this effect was reversed by addition of dexamethasone (40.2% vs 8.9%, p < 0.0005). These data support SCC and ILC2 expansion as well as increased IL-25 production in nasal polyps and may represent early events in the pathogenesis of CRSwNP. IL-13 stimulates proliferation of SCC in a feed-forward loop, a process that is steroid-sensitive.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is commonly characterized by type-2 inflammation. It is established that group-2 innate lymphoid cells (ILC2s) are a subset of immune cells important in orchestrating mucosal type-2 response. IL-25 is an epithelial-derived cytokine that is a critical activator of ILC2s. Recent evidence demonstrates that specialized taster epithelial cells, such as solitary chemosensory cells (SCCs), may be producers of IL-25. To elucidate the relationship between SCCs and ILC2s in CRSwNP, we sought to quantify ILC2s and SCCs to determine if these cell types are enriched in nasal polyps compared to healthy sinonasal mucosa. METHODS: We quantified SCCs and ILC2s using multicolor flow cytometry in nasal polyps and non-inflamed turbinate mucosa from seven patients and investigated the role of IL-13 and dexamethasone on SCC frequency using tissue explants of nasal polyps and turbinate mucosa. RESULTS: SCCs were found to be the primary source of IL-25. Nasal polyps demonstrated higher populations of SCCs (33.0% vs 5.6%, p < 0.001) and ILC2s (2.40% vs 0.19%, p = 0.008) compared to patient-matched nonpolypoid turbinates. In cultured polyp explants, exogenous IL-13 increased the proportion of epithelial SCCs (40.2% IL-13 condition vs 28.9% untreated, p = 0.012), and this effect was reversed by addition of dexamethasone (40.2% vs 8.9%, p < 0.0005). CONCLUSION: These data support SCC and ILC2 expansion as well as increased IL-25 production in nasal polyps and may represent early events in the pathogenesis of CRSwNP. IL-13 stimulates proliferation of SCC in a feed-forward loop, a process that is steroid-sensitive.
