Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a heterogeneous condition characterized by differing inflammatory endotypes. The identification of suitable biomarkers could enable personalized approaches to treatment selection. OBJECTIVE This study aimed to identify and summarize clinical studies of biomarkers in adults with CRS in order to inform future research into CRS endotypes. METHODS We conducted systematic searches of MEDLINE and Web of Science from inception to January 30, 2022 and included all clinical studies of adult CRS patients and healthy controls measuring biomarkers using enzyme-linked immunosorbent assays or Luminex immunoassays. Outcomes included the name and tissue type of identified biomarkers and expression patterns within CRS phenotypes. Study quality was assessed using the National Institutes of Health quality assessment tool for observational cohort and cross-sectional studies. A narrative synthesis was performed. RESULTS We identified 78 relevant studies involving up to 9394 patients, predominantly with CRS with nasal polyposis. Studies identified 80 biomarkers from nasal tissue, 25 from nasal secretions, 14 from nasal lavage fluid, 24 from serum, and one from urine. The majority of biomarkers found to distinguish CRS phenotypes were identified in nasal tissue, especially in nasal polyps. Serum biomarkers were more commonly found to differentiate CRS from controls. The most frequently measured biomarker was IL-5, followed by IL-13 and IL-4. Serum IgE, IL-17, pentraxin-3 and nasal phospho-janus kinase 2, IL-5, IL-6, IL-17A, granulocyte-colony stimulating factor, and interferon gamma were identified as correlated with disease severity. CONCLUSION We have identified numerous potential biomarkers to differentiate a range of CRS phenotypes. Future studies should focus on the prognostic role of nasal tissue biomarkers or expand on the more limited studies of nasal secretions and nasal lavage fluid.We registered this study in PROSPERO (CRD42022302787).

Abstract
OBJECTIVE Some previous studies have shown an increased prevalence of allergic fungal rhinosinusitis (AFRS) among young, black patients with poor access to health care; however, results have been mixed. The purpose of this study was to investigate the relationship between social determinants of health and AFRS. DATA SOURCES PubMed, Scopus, CINAHL. REVIEW METHODS A systematic review was performed searching for articles published from date of inception to September 29, 2022. English language articles describing the relationship between social determinants of health (i.e., race, insurance status) and AFRS as compared to chronic rhinosinusitis (CRS) were selected for inclusion. A Meta-analysis of proportions with comparison (Δ) of weighted proportions was conducted. RESULTS A total of 21 articles with 1605 patients were selected for inclusion. The proportion of black patients among AFRS, chronic rhinosinusitis with nasal polyps (CRSwNP), and chronic rhinosinusitis without nasal polyps (CRSsNP) groups was 58.0% [45.3%-70.1%], 23.8% [14.1%-35.2%], and 13.0% [5.1%-24.0%], respectively. This was significantly higher among the AFRS population compared to both the CRSwNP population (Δ34.2% [28.4%-39.6%], p < .0001) and the CRSsNP population (Δ44.9% [38.4%-50.6%], p < .0001). The proportion of patients who were either uninsured or covered by Medicaid among the AFRS, CRSwNP, and CRSsNP populations was 31.5% [25.4%-38.1%], 8.6% [0.7%-23.8%], and 5.0% [0.3%-14.8%], respectively. This was significantly higher among the AFRS group than the CRSwNP group (Δ22.9% [15.3%-31.1%], p < .0001) and the CRSsNP group (Δ26.5% [19.1%-33.4%], p < .0001). CONCLUSION This study confirms that AFRS patients are more likely to be Black and either uninsured or on subsidized insurance than their CRS counterparts.

Abstract
Background Chronic rhinosinusitis (CRS) is a clinical syndrome primarily characterized by long-term mucosal inflammation of the nasal cavity and sinuses. The pathogenesis of CRS is still unclear due to its high heterogeneity. A number of studies have recently focused on the sinonasal epithelium. Thus, there has been a quantum leap in awareness of the role of the sinonasal epithelium, which is now understood as an active functional organ rather than simply an inert mechanical barrier. Undoubtedly, epithelial dysfunction plays a vital role in the onset and development of CRS. Objective In this article, we discuss the potential contribution of sinonasal epithelium dysfunction to CRS pathogenesis and explore a few current and developing therapeutic options targeting the sinonasal epithelium. Results Impaired mucociliary clearance (MCC) and an abnormal sinonasal epithelial barrier are usually considered to be the main causative factors in CRS. Epithelial-derived bioactive substances, such as cytokines, exosomes, and complements, play a vital role in the regulation of innate and adaptive immunity and contribute to the pathophysiological alterations of CRS. The phenomena of epithelial-mesenchymal transition (EMT), mucosal remodeling, and autophagy observed in CRS offer some novel insights into the pathogenesis of this disease. In addition, existing treatment options targeting disorder of sinonasal epithelium can help to relieve the main symptoms associated with CRS to some extent. Conclusion The presence of a normal epithelium is fundamental for maintaining homeostasis in the nasal and paranasal sinuses. Here, we describe various aspects of the sinonasal epithelium and highlight the contributions of epithelial dysfunction to CRS pathogenesis. Our review provides sound evidence of the need for in-depth study of the pathophysiological alterations of this disease and for the development of novel epithelium-targeting alternative treatments.

Abstract
In patients with chronic rhinosinusitis with nasal polyps, primary human sinonasal epithelial cell (HSNEC) 1α-hydroxylase levels are reduced, as is their ability to metabolize 25-hydroxycholecalciferol [25(OH)D3] to its active metabolite, 1α,25-dihydroxyvitamin D3 [1,25(OH)2D3]. In this study, we sought to identify the factor responsible for the regulation of HSNEC metabolism of 25(OH)D3, focusing on C3 and C3a. Multiple inhaled irritants trigger the release of complement components, C3 and C3a, leading to suppression of 1α-hydroxylase levels in HSNECs. Recombinant C3a was able to decrease 1α-hydroxylase and impair 25(OH)D3 to 1,25(OH)2D3 metabolism, while addition of a C3a receptor antagonist restored conversion. Conversely, 1,25(OH)2D3 suppressed Aspergillus fumigatus-induced C3 and C3a levels in HSNEC supernatant. Given the ability of 1,25(OH)2D3 to modulate LL37 in other cell types, we examined its regulation in HSNECs and relationship to C3a. 1,25(OH)2D3 stimulated the secretion of LL37, whereas A. fumigatus and C3a suppressed it. Conversely, LL37 reduced the release of C3/C3a by HSNECs. Lastly, oral steroid use and in vitro dexamethasone application both failed to increase 1α-hydroxylase or reduce C3a levels. In summary, in this article, we describe for the first time a novel relationship between complement activation and local vitamin D metabolism in airway epithelial cells. The presence of elevated C3/C3a in patients with asthma and/or chronic rhinosinusitis with nasal polyps may account for their impaired HSNEC 25(OH)D3 to 1,25(OH)2D3 metabolism and explain why they receive limited therapeutic benefit from oral vitamin D3 supplementation.

Abstract
BACKGROUND Various nasal polyp (NP) scoring systems have been proposed and used in the literature. However, no single system has been identified as superior. Correlations between NP scoring systems and patient symptoms, quality of life (QOL) or olfaction vary widely. METHODS A systematic search of PubMed, CINAHL, Scopus, and Cochrane Library was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline. Any study examining endoscopy scores and symptom, QOL or olfaction measures in cross sectional manner or after therapeutic intervention were included. RESULTS This review identified 55 studies for a pooled meta-analysis of Lund-Kennedy (LK-NP) polyp scores (N = 6), Meltzer scores (N = 6), Nasal polyp scores (NPS; N = 19), Total polyp score (TPS; N=8) Lilholdt scores (N = 8), Olfactory cleft endoscopy score (OCES; N =4), Discharge, inflammation, polyp/edema score (DIP; N = 2), and Perioperative sinus endoscopy score (POSE; N = 2). Meta-regression assessed correlations between NP grading systems and SNOT-22, nasal congestion scores, total nasal symptom scores (TNSS), and Smell Identification Test-40 (SIT40). None of the NP grading systems correlated significantly with any symptom, QOL or olfactory metric. In intervention studies of surgery or monoclonal antibody treatment, changes in NPS scores did not correlate with any patient reported outcome measure (PROM) or olfactory outcomes. CONCLUSION Current NP endoscopic scoring systems are not associated with PROMs such as SNOT-22, nasal congestion scores, and TNSS as well as objective measures of olfaction. NP grading systems with improved clinical utility are needed.

Abstract
Vitamin D plays an active role in the modulation of innate and adaptive immune responses as well as in the protection against respiratory pathogens. Evidence for this immunomodulatory and protective role is derived from observational studies showing an association between vitamin D deficiency, chronic airway diseases and respiratory infections, and is supported by a range of experimental studies using cell culture and animal models. Furthermore, recent intervention studies have now shown that vitamin D supplementation reduces exacerbation rates in vitamin D-deficient patients with chronic obstructive pulmonary disease (COPD) or asthma and decreases the incidence of acute respiratory tract infections. The active vitamin D metabolite, 1,25-dihydroxy-vitamin D (1,25(OH)2D), is known to contribute to the integrity of the mucosal barrier, promote killing of pathogens (via the induction of antimicrobial peptides), and to modulate inflammation and immune responses. These mechanisms may partly explain its protective role against infections and exacerbations in COPD and asthma patients. The respiratory mucosa is an important site of local 1,25(OH)2D synthesis, degradation and signaling, a process that can be affected by exposure to inflammatory mediators. As a consequence, mucosal inflammation and other disease-associated factors, as observed in e.g., COPD and asthma, may modulate the protective actions of 1,25(OH)2D. Here, we discuss the potential consequences of various disease-associated processes such as inflammation and exposure to pathogens and inhaled toxicants on vitamin D metabolism and local responses to 1,25(OH)2D in both immune- and epithelial cells. We furthermore discuss potential consequences of disturbed local levels of 25(OH)D and 1,25(OH)2D for chronic lung diseases. Additional insight into the relationship between disease-associated mechanisms and local effects of 1,25(OH)2D is expected to contribute to the design of future strategies aimed at improving local levels of 1,25(OH)2D and signaling in chronic inflammatory lung diseases.

Abstract
BACKGROUND Respiratory epithelium is a key defense against inhaled pathogens. Vitamin D3 (VD) has been suggested to modulate airway inflammation; however, its effect on innate airway defenses, the physical barrier, mucociliary apparatus, and cytokine release remains unclear. OBJECTIVE To investigate the outcomes of VD application prior to challenge in an in vitro model of human sinonasal epithelium, through assessment of epithelial transepithelial resistance (TER), cilia beat frequency (CBF), and interleukin (IL)-6 release, and secondarily to determine whether topical VD is beneficial to patients with inflammatory sinonasal pathology. METHODS Primary human sinonasal epithelial cells from patients with eosinophilic chronic rhinosinusitis (eCRS) and healthy controls were cultured in air-liquid interface (ALI). Well-differentiated cultures from each patient were pretreated for 24 hours with 4 different VD doses. Toxicity was quantified at 24 hours in unchallenged ALI by lactate dehydrogenase (LDH) assay. Innate responses were assessed by measuring TER and CBF before and up to 24 hours after house dust mite Dermatophagoides pteronyssinus challenge. IL-6 release was evaluated 24-hour postchallenge. RESULTS Fifteen patients (53 ± 13.5 years, 60% females, 53% eCRS) representing 120 ALI wells were assessed. VD (0, 25, 50, 150 IU/mL) released less LDH than vehicle, indicating noncytotoxicity (0.15 ± 0.02; 0.15 ± 0.00; 0.14 ± 0.02; 0.11 ± 0.01 vs 0.17 ± 0.03, P = .004). VD increased TER for eCRS wells at 5 minutes (50 IU/mL: Δ6.76 ± 3.93 vs Δ3.87 ± 2.46, P = .04) and 24 hours (50 IU/mL: Δ0.88 ± 0.49 vs Δ0.40 ± 0.42, P = .02; 150 IU/mL: Δ1.06 ± 0.58 vs Δ0.47 ± 0.46, P = .01). CBF increased at 1 hour for eCRS wells (50 IU/mL: Δ0.62 ± 0.14 vs Δ0.41 ± 0.13, P = .001; 150 IU/ml: Δ0.60 ± 0.13 vs Δ0.38 ± 0.11, P < .001). IL-6 release was similar between normal and eCRS wells. CONCLUSION Topical VD supplementation in eCRS patients may be beneficial for innate epithelial defenses. VD is noncytotoxic and does not adversely affect the physical barrier, mucociliary apparatus, or IL-6 release. Further studies should clarify its potential as a therapeutic agent.

Abstract
:
The growing interest in the new role of vitamin D, particularly as an immunomodulatory
factor, has spurred basic research and the development of clinical trials to better understand the
influence of supplementation on various diseases. Vitamin D is an important nutrient factor in human
health due to its role in calcium metabolism regulation, cellular growth, differentiation and its
fundamental discovered activity in immune functions. It has influenced different diseases,
particularly inflammatory and autoimmune diseases, through immune response regulation,
modulating innate and adaptive immunity.
:
The aim of this review was to explore the role of vitamin D in the main respiratory diseases in
children such as asthma, chronic rhinosinusitis, cystic fibrosis and recurrent respiratory infections.

Abstract
Background In the past, the airway epithelium was thought to be primarily an inert physical barrier. We now know that the upper airway epithelium plays a critical role in both innate and adaptive immunity, and that epithelial dysfunction is strongly associated with inflammatory airway disease. The pathogenesis of chronic rhinosinusitis is poorly understood, but growing evidence supports a key role for the airway epithelium in the pathophysiology of the disease. Objective The purpose of this study is to explore our current understanding of how dysfunction in human sinonasal epithelial cells (HSNECs) contributes to the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) and to examine how current and developing therapies affect epithelial cell functions. Methods A literature review of papers published in English pertaining to epithelial cell dysfunction in patients with CRSwNP was performed using the PubMed database. The search utilized combinations of the following key words: sinusitis, polyps, epithelium, pathophysiology, barrier function, dendritic cells, eosinophils, T cells, complement, mucociliary clearance, vitamin D, cytokines, chemokines, taste receptors, steroids, saline, and therapy. Results HSNEC mucociliary clearance, barrier function, secretion of cytokines, influence on dendritic cells, influence on T-cells, regulation of eosinophils, vitamin D metabolism, complement production, and taste receptor function are altered in patients with CRSwNP and contribute to the pathogenesis of the disease. Current therapies utilized to manage CRSwNP counteract the effects of HSNEC dysfunction and relieve key symptoms of the disease. Conclusion HSNECs are key players in both innate and adaptive immunity, and altered epithelial functions are closely intertwined with the pathogenesis of CRSwNP. Our review supports further investigation of altered HSNEC function in patients with CRSwNP and supports development of novel epithelial-targeted therapies for its management.

Abstract
OBJECTIVE To evaluate the serum vitamin D level in patients with chronic rhinosinusitis with nasal polyps and its correlation with the disease severity. SETTING Hospital of Zhejiang University. STUDY DESIGN Retrospective analysis of collected data. SUBJECTS AND METHODS Patients with chronic rhinosinusitis with or without nasal polyps who underwent endoscopic sinus surgery were recruited. Demographic information including age, gender, body mass index, smoke history, atopic status and asthma was collected. Disease severity was measured by the Lund-Mackay CT score and Sino-Nasal Outcome Test-22 score. Serum 25-hydroxyvitamin D3 was measured by enzyme-linked immunosorbent assay preoperatively. RESULTS Serum 25-hydroxyvitamin D3 levels were significantly lower in patients with nasal polyps (CRSwNP, 38.2 ± 9.1 nmol/L; CRSsNP, 48.94 ± 12.1 nmol/L; control, 54.1 ± 17.1 nmol/L. p < 0.001), and the levels were significantly associated with the preoperative Sino-Nasal Outcome Test-22 score (p = 0.013), but not with the Lund-Mackay score (p = 0.126). Furthermore, serum 25-hydroxyvitamin D3 levels were associated with the subjective improvement six months postoperatively (p < 0.001), CONCLUSION: Serum 25-hydroxyvitamin D3 levels are lower in Chinese CRSwNP patients. These 25-hydroxyvitamin D3 levels are associated with SNOT-22 score. Preoperative 25-hydroxyvitamin D3 level may impact on the symptom improvement after surgery.

Abstract
OBJECTIVES Chronic rhinosinusitis (CRS) is a disease that represents a challenging therapeutic problem. Vitamin D and its receptors (VDR) are involved in the regulation of the immune system and may play role in CRS. Objectives of this study were to assess the relationships between the total concentration of vitamin D (25VD3) in sera, vitamin D receptor (VDR) expression, 1α-hydroxylase expression, and clinical data, including age, gender, Sino-Nasal Outcome Test (SNOT-22), computerized tomography (CT) scan, allergy status, and vitamin D supplementation in CRS patients with (CRSwNP) and without nasal polyps (CRSsNP), and in a control group. METHODS The studied group comprised 52 patients with CRS without nasal polyps (sNP), 55 with CRS with nasal polyps (wNP), and 59 in the control group. The endpoints were determined by appropriate methods. We conducted immunohistochemical staining of gathered tissue from the ostiomeatal complex for determination of VDR and 1α-hydroxylase. Analytical results were compared with clinical data as already noted. RESULTS A decrease in VDR nuclear staining occurred in CRS patients as compared to controls. Insignificant differences were observed in 1α-hydroxylase, expression in all studied groups, while VDR and cytochrome CYP27B1 protein expression (1α-hydroxylase) correlated with clinical data. CONCLUSIONS The data provide evidence that indicates that vitamin D and its receptor and enzymes may play a role in CRS.

Abstract
Allergic rhinitis (AR) and chronic rhinosinusitis with nasal polyps (CRSwNP) are inflammatory diseases of the upper airway, with a similar immunologic profile, characterized by aberrant and persistent type 2 inflammation. One cell population that has been identified as altered in both disease types is regulatory T cell (Treg). Tregs have the capacity to modulate T-effector function and suppress inflammatory cytokine production in a broad range of cell types. Given the ability of Tregs to control inflammation, the role of Tregs in respiratory diseases has attracted much attention. As discussed in this article, alterations in the Treg numbers and function, or both, have been identified in AR and CRSwNP, although much of the data is conflicting. Here, we explored what is known and, in many cases, unknown about the mechanisms by which Tregs differentiate and function, and how these functions can be controlled in the mucosal microenvironment. By gaining a greater understanding of these processes, it may be possible to harness the natural immunosuppressive activity of Tregs to ameliorate the chronic inflammation associated with AR and CRSwNP.

Abstract
BACKGROUND In several inflammatory disorders, altered peripheral blood mononuclear leukocyte (PBML) glucocorticoid (GC) receptor isoform expression has been associated with GC resistance and disease severity. However, it is unclear if PBML GC receptor isoforms are expressed differentially and are associated with worsened disease severity in chronic rhinosinusitis (CRS). METHODS PBMLs were isolated from control (n = 8), CRS without nasal polyps (CRSsNP) (n = 8), atopic CRS with nasal polyps (CRSwNP) (n = 8), non-atopic CRSwNP (n = 8), and allergic fungal rhinosinusitis (AFRS) (n = 8) patients. Demographics, atopic status, asthmatic status, 22-item Sino-Nasal Outcome Test (SNOT-22) scores, Lund-Kennedy nasal endoscopy scores, Lund-Mackay sinus computed tomography (CT) scores, Kennedy Osteitis scores, and GC utilization 6 months postoperatively were collected. Intracellular immunostaining was then performed for functional GC receptor α (GCRα) and nonfunctional GC receptor β (GCRβ), followed by flow cytometry analysis of geometric mean fluorescent intensity (MFI) and the percentage of cells expressing each GC receptor isoform. RESULTS Compared to controls, each CRS subtype had decreased PBML GCRα and GCRα:GCRβ MFI expression, but no difference in GCRβ expression. Decreasing PBML GCRα in AFRS was associated with increasing Lund-Mackay sinus CT scores (r = -0.880, p =0.004). No significant associations were found between GC receptor isoform expression and other clinical measures. CONCLUSION CRS patients have reduced functional PBML GCRα expression and decreased GCRα:GCRβ compared to controls. Reductions in GCRα in AFRS are associated with worsening Lund-Mackay sinus CT scores. The clinical implications of decreased functional GC receptor expression merits further investigation.

Abstract
Background Currently vitamin D3 (VD3) or cholecalciferol is considered an immunomodulator that may be implicated in nasal polyposis (NP) pathophysiology. Objectives This study aimed to investigate if deficiency of VD3 is associated with the presence of NP in patients with cystic fibrosis (CT) and patients with chronic rhinosinusitis (CRS). Methods In total, 152 adult participants were included in five phenotypic groups: CT with NP (CTwNP) (n = 27), CT without NP (CTsNP) (n = 31), CRS with NP (CRSwNP) (n = 32), CRS without NP (CRSsNP) (n = 30), and controls (n = 32). The serum levels of 25(OH)-VD3 <20 ng/mL are considered as a deficiency, 21–29 ng/mL as insufficiency, and >30 ng/mL as sufficiency. Endoscopic and imaging staging of the mucosal disease performed with the Lund-Kennedy (LK) and Lund-Mackay (LM) scoring systems, respectively. The genotype of the patients with CT and the nasal microbial colonization of the patients with CT and patients with CRS were also recorded. Results The patients with CTwNP had the lowest percentage of sufficiency in VD3 and the highest percentage in insufficiency among all the groups. The LM imaging scores were inversely correlated with the VD3 levels in both arms of the study (CT and CRS). Moreover, the LK endoscopic scores had a similar correlation in the CT groups; however, this was not the case with the CRS groups. The genotype of the patients with CT was not correlated with the VD3 serum levels. The patients with positive microbial colonization (mainly Pseudomonas and Staphylococcus aureus) had significantly lower VD3 serum levels in both the CT and CRS process. Conclusion VD3 deficiency seemed to be associated with the presence of nasal polyps in the patients with CRS and in the patients with CT in a similar manner. The lower the level of serum VD3, the more severe the mucosal disease was found in the imaging studies and the more frequent microbial colonization of the patients with CT and the patients with CRS.

Abstract
BACKGROUND CD8+ T cells and natural killer (NK) cells are cytotoxic cells that use granzyme B (GrB) and perforin. Defective cytotoxic function is known to play a role in dysregulated immune response as seen in chronic sinusitis, also referred to as chronic rhinosinusitis (CRS). However, to our knowledge, in the United States, neither GrB or perforin expression has been reported in patients with CRS. OBJECTIVE The aim of this study was to investigate sinonasal cytotoxic cells, their mediators, and cell-specific distribution of these mediators in patients with CRS with nasal polyp (CRSwNP) and in patients with CRS without nasal polyp (CRSsNP). METHODS Blood and sinus tissue samples were taken from patients with CRSsNP (n = 8) and CRSwNP (n = 8) at the time of surgery. Control subjects (n = 8) underwent surgery for cerebrospinal fluid leak repair or to remove non-hormone-secreting pituitary tumors. The cells were analyzed via flow cytometry by using CD8 expression to identify cytotoxic T cells and CD56 expression to identify NK cells. Intracellular GrB and perforin expression were analyzed with flow cytometry. RESULTS We observed no significant differences in plasma or peripheral blood immune cell numbers or specific levels of GrB or perforin among the groups. In the sinonasal mucosa of the patients with CRSsNP and the patients with CRSwNP, there was a significant decrease in GrB and perforin levels (p < 0.05) despite similar or increased numbers of cytotoxic cells when compared with the controls. The overall decrease in GrB and perforin in the sinonasal mucosa of the patients with CRSsNP and the patients with CRSwNP was due to decreased T cell production. There was no difference in total NK cell count or expression of perforin or GrB among all the groups. CONCLUSION Total levels of sinonasal GrB and perforin were decreased in the sinonasal mucosa of both the patients with CRSwNP and the patients with CRSsNP compared with the controls, whereas sinonasal CD8+ T cells, (but not NK cells,), intracellular stores of GrB and perforin were reduced in the patients with CRSwNP compared with the controls.

Dietary vitamin D3 deficiency exacerbates sinonasal inflammation and alters local 25(OH)D3 metabolism. PLoS One 2017; 12:e0186374.

Abstract
RATIONALE Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) have been shown to be vitamin D3 (VD3) deficient, which is associated with more severe disease and increased polyp size. To gain mechanistic insights into these observational studies, we examined the impact of VD3 deficiency on inflammation and VD3 metabolism in an Aspergillus fumigatus (Af) mouse model of chronic rhinosinusitis (Af-CRS). METHODS Balb/c mice were fed control or VD3 deficient diet for 4 weeks. Mice were then sensitized with intraperitoneal Af, and one week later given Af intranasally every three days for four weeks while being maintained on control or VD3 deficient diet. Airway function, sinonasal immune cell infiltrate and sinonasal VD3 metabolism profiles were then examined. RESULTS Mice with VD3 deficiency had increased Penh and sRaw values as compared to controls as well as exacerbated changes in sRaw when coupled with Af-CRS. As compared to controls, VD3 deficient and Af-CRS mice had reduced sinonasal 1α-hydroxylase and the active VD3 metabolite, 1,25(OH)2D3. Differential analysis of nasal lavage samples showed that VD3 deficiency alone and in combination with Af-CRS profoundly upregulated eosinophil, neutrophil and lymphocyte numbers. VD3 deficiency exacerbated increases in monocyte-derived dendritic cell (DC) associated with Af-CRS. Conversely, T-regulatory cells were decreased in both Af-CRS mice and VD3 deficient mice, though coupling VD3 deficiency with Af-CRS did not exacerbate CD4 or T-regulatory cells numbers. Lastly, VD3 deficiency had a modifying or exacerbating impact on nasal lavage levels of IFN-γ, IL-6, IL-10 and TNF-α, but had no impact on IL-17A. CONCLUSIONS VD3 deficiency causes changes in sinonasal immunity, which in many ways mirrors the changes observed in Af-CRS mice, while selectively exacerbating inflammation. Furthermore, both VD3 deficiency and Af-CRS were associated with altered sinonasal VD3 metabolism causing reductions in local levels of the active VD3 metabolite, 1,25(OH)2D3, even with adequate circulating levels.

Abstract
BACKGROUND Vitamin D deficiency is associated with many inflammatory respiratory disease states. However, serum vitamin D concentrations may not reflect tissue-specific availability. In this study we sought to assess the local expression of genes essential in vitamin D regulation in chronic rhinosinusitis (CRS). METHODS A cross-sectional study of adult patients undergoing endoscopic sinus surgery was performed. Patients were defined as having CRS with polyps (CRSwNP) or without polyps (CRSsNP), or normal sinus mucosa. Sinus mucosal biopsies were assessed using quantitative polymerase chain reaction to determine expression of genes encoding the vitamin D receptor (VDR), 25-hydroxylase (CYP2R1), 1α-hydroxylase (CYP27B1), and 24-hydroxylase (CYP24A1). Expression levels correlated with serum 25(OH)D [sum 25(OH)D2 and 25(OH)D3 ], the 22-item Sinonasal Outcome Test (SNOT-22), and Nasal Symptom Score (NSS). Separate analyses were performed for patients grouped by tissue eosinophilia. RESULTS Thirty-one patients were assessed (age 49.47 ± 18.14 years, 48.4% female), including 8 CRSsNP, 10 CRSwNP, and 13 controls. CRSsNP and CRSwNP mucosa exhibited decreased CYP27B1 compared with controls (0.0437 [Interquartile range (IQR) 0.0999] vs 0.3260 [IQR 2.9384] vs 0.6557 [IQR 1.1005], p = 0.039), whereas CYP24A1 was upregulated (0.8522 [IQR 1.3170] vs 1.2239 [IQR 4.4197] vs 0.1076 [IQR 0.1791], p = 0.025). CYP24A1 was upregulated in both non-eosinophilic CRS and eosinophilic CRS (1.1337 [IQR 2.3790] vs 0.9555 [IQR 3.2811] vs 0.1076 [IQR 0.1791], p = 0.033). Significant correlations were observed between NSS and CYP2R1 (r = -0.432, p = 0.022), CYP24A1 (r = 0.420, P = 0.026), and VDR (r = 0.425, p = 0.024), although no correlations with serum 25(OH)D were observed. CONCLUSIONS The local regulation of vitamin D in sinonasal tissue during CRS may be independent of serum 25(OH)D levels. Vitamin D may be dysregulated at multiple levels, with decreased transcription of the metabolic gene CYP27B1 and increased transcription of the catabolic gene CYP24A1 observed.
