Ghazavi H, Hashemi SM, Jafari S. The Effect of Vitamin D Supplement on the Relapsing Incidence of Rhinosinusitis with Nasal Polyposis after Fuctional Endoscpoic Sinus Surgery. Adv Biomed Res 2023; 12:29. [PMID: 37057244 PMCID: PMC10086644 DOI: 10.4103/abr.abr_237_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 12/03/2021] [Accepted: 12/07/2021] [Indexed: 04/15/2023] Open
Abstract
Background Nasal polyp (NP) is the most common benign tumor that can cause nasal obstruction and more annoying problems in patients. Recently, investigators have been focusing on complementary therapies alone or in conjunction with endoscopic nasal and sinus surgery. However, given the association of Vitamin D (VD) deficiency and chronic rhinosinusitis with nasal polyposis (CRSwNP) in previous studies, it may be possible to prevent the recurrence of NP and the development of rhinosinusitis by controlling serum levels of VD and maintaining it at a normal level. The current study aimed to investigate the efficacy of VD supplementation in preventing CRSwNP recurrence after endoscopic surgery. Materials and Methods This clinical trial composed of vitamin D deficient patients with CRSwNP who were candidates for endoscopic sinus surgery in two groups of cases and controls. After endoscopic sinus surgery for all patients, we administered VD supplementation (50,000 IU) once a week for 8 weeks for cases and no further intervention for controls. The severity of symptoms was assessed using Sino-nasal outcome test (SNOT-22) and NP recurrence and recorded pre- and postintervention. Results The findings indicated a higher mean change of SNOT-22 in the case group compared to that of the control group (36.03 ± 10.71 vs. 29.90 ± 11.99; P = 0.041). Moreover, the percentage of NP recurrence in cases was lower than controls; so that receiving VD supplementation has significantly reduced the chance of NP recurrence (odd ratio [95% confidence interval]: 0.298 [0.099-0.900]; P = 0.032). Conclusion According to the result of the study, the administration of VD supplementation after endoscopic sinus surgery can reduce the severity of CRSwNP symptoms and NP recurrence significantly.

Abstract
Vitamin D is thought to play an inflammatory modulatory role in the pathogenesis of chronic rhinosinusitis with nasal polyposis (CRSwNP) & it also affects the severity of inflammation so the study was focused on the evaluation of serum vitamin D & interleukins in CRSwNP. The prospective study was conducted on clinic-radiological confirmed cases. The patients were not operated prior, clubbed under primary nasal polyposis (PNP) group and the patients were operated prior, clubbed under recurrent nasal polyposis (RNP) group. The subjective and objective severity of the disease was assessed by sino-nasal outcome score (SNOT 22) & NCCT PNS & orbit. Serum levels of cytokines (IL4, IL 5, and IL 13) were quantified using the ELISA method using the Human Interleukin antibody coated ELISA kit. Measurement of vitamin D was done by using recombinant ruthenium-labelled VDBP. There was a significant difference in Vitamin D, AEC, IL 4, IL 5, IL 13 levels in the disease groups compared to control group. Low vitamin D, high SNOT & high absolute eosinophil count (AEC) count was noticed in both disease groups. Vitamin D may play a significant role in nasal polyposis formation. For the establishment of interaction, a community based larger study is required as the prevalence of low vitamin D level is high in Indian population.

Association of serum vitamin D with Chronic RhinoSinusitis in adults residing at high altitudes. Eur Arch Otorhinolaryngol 2020; 278:1067-1074. [PMID: 32945930 DOI: 10.1007/s00405-020-06368-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Accepted: 09/10/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE To evaluate the association of serum vitamin D levels with chronic rhinosinusitis (CRS) in population residing at high altitudes and to assess its correlation with severity of CRS. METHODS A prospective case-control study comparing vitamin D in 60 cases (30 with nasal polyposis and 30 without) and 31 controls was carried out. Correlation of vitamin D with severity of disease (Lund Mackay CT/LMS and endoscopic Lund Kennedy scores/LKS) was assessed using Spearman's correlation (rs). Logistic regression analysis using vitamin D and confounding factors (Age and gender only, as other variables like smoking, bronchial asthma were exclusion criteria) as dependent and CRS (presence/absence) as independent variable, was also conducted. RESULTS A significantly lower vitamin D levels were found in CRS (14.60 ± 7.68 ng/ml), CRSwNP (13.70 ± 7.88 ng/ml) and CRSsNP (15.49 ± 7.50 ng/ml), when compared to controls (29.36 ± 7.49 ng/ml). Non allergic cases when compared with controls, showed significantly lower vitamin D levels (13.91 ± 6.78 compared to 29.36 ± 7.49 ng/ml). LMS and LKS in CRS showed a moderate correlation with vitamin D (rs: - 0.604 for LMS, rs: - 0.595 for LKS). Logistic regression analysis showed vitamin D levels (Odds-Ratio 0.783) to be an independent predictive factor of CRS. CONCLUSION A significantly lower vitamin D level is associated with CRS, irrespective of presence or absence of nasal polyposis in adults residing at high altitudes. Vitamin D is an independent predictive factor for CRS. There is an inverse moderate correlation of severity of CRS with vitamin D.

Abstract
Introduction
Vitamin D is known to have immunomodulatory functions and has action on chronic inflammatory processes, such as nasal polyposis.
Objective
The present study assessed the levels of 25-hydroxy vitamin D and high-sensitivity C-reactive protein (hs-CRP) in patients with nasal polyposis, as compared with healthy control subjects, and identified their association with disease severity in nasal polyposis. It further assessed the levels of 25-hydroxyl vitamin D and hs-CRP in patients with nasal polyposis and atopy and compared it with patients with nasal polyposis without atopy.
Methods
This was a cross-sectional study involving 2 groups: 80 patients with nasal polyposis and 80 healthy subjects. In patients with nasal polyposis, the disease severity is assessed by the sino-nasal outcome test (SNOT20) and by the Lund & Mackay staging system. Levels of 25-hydroxy vitamin D and hs-CRP were measured by enzyme-linked immunosorbent assay (ELISA).
Result
The mean 25-hydroxyl vitamin D levels (ng/ml) was 12.01 ± 7.29 for cases and 22.87 ± 14.95 for controls, with
p
< 0.0001. The mean hs-CRP levels (mg/L) was 5.99 ± 2.74 in cases and 2.41 ± 1.95 in controls, with
p
< 0.0001. The severity of polyposis correlated negatively with serum levels of 25-hydroxy vitamin D and positively with hs-CRP.
Conclusion
The study has thus shown significant correlation between vitamin D deficiency and inflammation in patients with nasal polyps.

Abstract
The pathogenesis of chronic rhinosinusitis (CRS) is still unknown, but it is accepted that various inflammatory factors are responsible for the different CRS subtypes. Vitamin D3 has been shown to alter inflammatory mediators in some diseases and its deficiency might also be associated with CRS with nasal polyposis (CRSwNP). Herein, we investigated serum vitamin D3 levels in patients with CRSwNP and its association with disease severity. In a cross-sectional study, 166 cases with CRSwNP and 172 healthy subjects were enrolled. Serum vitamin D3 levels were measured and compared in both groups. Furthermore, the relationship between serum vitamin-D3 level and the patient’s allergic status and severity of disease (clinically and based on computed tomographic imaging and nasal endoscopy) among patients with CRSwNP was assessed. Serum vitamin D3 level in the CRSwNP group was significantly lower than in the control group (P < 0.0001). After controlling for possible confounding factors, an increase in vitamin D level showed a protective effect in CRSwNP (OR = 0.69 95% CI:0.62-0.76). A negative correlation was found between serum vitamin-D3 level and the Lund-Mackay score (LMS) (P < 0.0001, R = – 0.66), the Lund-Kennedy score (LKS) (P < 0.0001, R = – 0.71) and the Sino-Nasal Outcome Test-22 (P < 0.001, R = – 0.49). Serum vitamin D level in the CRSwNP group was significantly lower than the control group. Disease severity, based on imaging, endoscopic and clinical criteria, was inversely associated with serum vitamin D levels.

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
Introduction Chronic rhinosinusitis is a highly heterogeneous chronic inflammation of the upper respiratory tract caused by immune dysfunction in human beings. However, the underlying etiology of this disease has not yet been well established. Several trials have revealed that serum vitamin D level abnormality might play a role in the pathophysiology of chronic rhinosinusitis. Objective The aim of present study was to perform a meta-analysis of studies to compare the serum vitamin D levels between patients with chronic rhinosinusitis and healthy controls and to evaluate the potential associations of serum vitamin D level with the occurrence of chronic rhinosinusitis. Methods Following the PRISMA guidelines, relevant databases incorporating Pubmed, Web of Science, Embase and Cochrane Library were searched from inception to December 1, 2018. Funnel plot symmetry and Egger’ test were used to detect publication biases. The outcomes were presented as Weighted Mean Difference combined with 95% Confidence Intervals to estimate the difference of serum vitamin D levels between patients with chronic rhinosinusitis and controls. Higgins I2 value was used to test for heterogeneity between the included studies. Results Out of 176 studies, only eight studies involving 337 chronic rhinosinusitis patients and 179 healthy controls met the criteria and were included in the meta-analysis. In a pooled analysis of the studies, chronic rhinosinusitis patients showed decreased serum vitamin D status (WMD = −7.80, 95% CI −13.28 to −2.31, p = 0.000). Subgroups analyses based on study location (USA vs. Non-USA), types of biomarkers (25(OH)D3 vs. 25(OH)D) and the study design methods (retrospective vs. prospective) did not reveal heterogeneity. However, phenotypes of chronic rhinosinusitis, with versus without polyposis might account for some degree of heterogeneity. Meanwhile, a lower serum vitamin D level was observed in chronic rhinosinusitis with nasal polyps patients. Conclusion Our findings indicate that serum vitamin D level might be associated with patients with chronic rhinosinusitis as we detected a significant association between lower serum vitamin D status and chronic rhinosinusitis, especially in chronic rhinosinusitis with nasal polyps patients. However, further comprehensive studies are warranted in order to draw firm conclusions.

Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) with and without nasal polyposis is a chronic inflammatory disease of the sinuses and nasal mucosa. Recent evidence has indicated a relationship between serum 25-hydroxyl vitamin D (OH-VitD) deficiency and CRS. Regarding this, the present study aimed to compare the serum level of 25-OH-VitD in CRS patients with and without nasal polyposis and control groups. MATERIALS AND METHODS This study was conducted on 117 adult subjects in three groups of CRS with nasal polyposis (CRSwNP; n=32), CRS without nasal polyposis (CRSsNP; n=35), and healthy controls (n=50). The mean level of serum 25-OH-VitD in the three groups was measured by means of enzyme- linked immunosorbent assay. The data were analyzed using SPSS software (version 18). RESULTS Mean serum levels of 25-OH-VitD in CRSwNP, CRSsNP, and control groups were 12.52, 15.54, and 22.04 ng/ml, respectively. There was a significant difference between the case and control groups in terms of 25-OH-VitD level (P=0.0001). However, no significant difference was observed between the CRSwNP and CRSsNP groups in this regard (P=0.464). The women had a VitD deficiency odds ratio (OR) of 2.47, compared with men (OR=2.47, 95% CI=1.04-5.86). The OR of VitD deficiency with aging was obtained as 0.957 (95% CI=0.925-0.989). In this regard, older patients had a lower probability of VitD deficiency, compared to younger patients. CONCLUSION As the findings indicated, serum 25-OH-VitD was significantly lower in CRS patients, compared with that in the non-CRS subjects.

Abstract
Studying the pathophysiology of allergic fungal rhinosinusitis (AFRS) has proved challenging. While this clinical entity is easily distinguishable based on the clinical criteria set forth by Bent and Kuhn twenty-five years ago, studies examining type 2 inflammatory profiles in AFRS can make it seem more alike other CRS subtypes than it is different. Still, evolving research seems to clearly delineate this subtype from others in CRS. This review will critically evaluate the evolution of research examining the pathophysiology of AFRS and will conclude with a summary of the special considerations in the management of this fascinating disease.

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
OBJECTIVES Sickle cell anemia (SCA) and β -thalassemia major are well-recognized beta-globin gene disorders of red blood cells associated to mortality and morbidity included bone morbidities due to ineffective erythropoiesis and bone marrow expansion, which affect every part of the skeleton. While there are an abundance of described disease manifestations of the head and neck, the manner of paranasal sinuses involvement and its relations to β-thalassemia and SCA process was not studied yet. Therefore, the aim of this study was to investigate a possible increased risk of rhinosinusitis and the real pathogenetic mechanism of it, comparing these two hematological diseases using msCT, gold standard for paranasal sinuses evaluation. METHODS A retrospective analysis of 90 patients affected by β-thalassemia major or SCA (respectively 59 and 31) underwent allogeneic bone marrow transplantation (BMT), and 44 control subjects was performed. Both patient categories and control group have been subjected to hematological and radiological evaluation using 64-multidetector-row CT scanner without contrast injection. RESULTS Statistical analysis reveals that patients of the two study groups exhibit a significantly increased risk of sinusitis in comparison with the normal controls (RR: 3.55 for β-thalassemic pediatric subjects; RR: 3.35 for SCA pediatric subjects). A significant difference (p < 0,5) was found between the β -thalassemic patients on the one side, and SCA and control group on the other side, with regard to the evaluation of the typical anatomic alteration of maxillary sinus: β-thalassemic children had significant increase in the bone thickness of anterior and lateral sinus walls and significant reduction in volume and density compared to SCA patients and control group, with normal conditions of these parameters. CONCLUSIONS In these hematological patients, there is an increased incidence of sinonasal infections due their therapy-induced immunosuppression post transplantation. In β-thalassemic patients, furthermore, the specific anatomical variants play an important confounding factor in radiological interpretation of CT images. Therefore, a cranio-facial CT scan evaluation could be a useful tool in the management of upper airway infections after BMT and should be a routinely exams in order to avoid useless surgical or antibiotic approaches.

Abstract
The objective of the present study was to elucidate the possible correlations between the vitamin D3 level in the blood serum and lactase gene polymorphism (LCT-13910 T>C) in the patients presenting with chronic polypous rhinosinusitis (CPRS). The study included 50 patients with this condition and 14 subjects comprising the control group. The variants of lactase gene polymorphism (LCT-13910 T>C) were identified with the use of polymerase chain reaction (PCR) in real time. The total level of serum vitamin D3 (VD3) was determined by means of the immunochemical analysis (the electrochemiluminescence technique). In the group of patients presenting with chronic polypous rhinosinusitis, the level of VD3 in the blood serum ranged from 48 nm/l to 85 nm/l (mean 60 nm/l) compared with that in the patients of the control group (from 78 nm/l to 112 nm/l; mean 97 nm/l) . The level of vitamin D3 'below the normal values' was documented in 71% of the patients with CPRS in comparison with 7% in the control subjects. Lactase gene polymorphism (LCT-13910 CC, CT) suggesting pronounced and latent hypolactasia was identified in 94% of the patients with CPRS compared with 78.6% in the control group. The occurrence of the CC genotype in the patients of both study groups was virtually identical: 52% in the patients presenting with chronic polypous rhinosinusitis and 57% in the control group. CT polymorphism was identified in 42% of the patients with CPRS and in 21% of the control subjects. The significant difference between the patients of the two groups was documented for the occurrence of TT polymorphism: 6% among the patients with CPRS and 21% in the controls (i.e. much higher in the healthy subjects). There was no significant difference between the serum levels of vitamin D3 either among the patients with CPRS having LCT-13910 gene polymorphisms (CC, CT, TT) or among the control subjects. It is concluded that the study revealed the higher levels of vitamin D3 in the blood sera from the control subjects in comparison with that in the patients with chronic polypous rhinosinusitis. Moreover, the patients of the latter group more frequently exhibited the variant of the LCT CT-13910 gene polymorphism suggesting latent hypolactasia whereas the subjects comprising the control group more frequently had the variant of the LCT CT-13910 gene polymorphism indicative of the normal tolerance of lactose.

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.

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
Th17 cells play a critical role in several autoimmune diseases, including psoriasis and psoriatic arthritis (PsA). Psoriasis is a chronic inflammatory skin disease associated with systemic inflammation and comorbidities, such as PsA. PsA develops in nearly 70% of patients with psoriasis, and osteoclasts associated bone erosion is a hallmark of the disease. Thus far, the effect of Th17 cells on osteoclastogenesis via direct cell-to-cell interactions is less understood. In this study, we observed that Th17 cells directly promote osteoclast differentiation and maturation via expression of receptor activator of nuclear factor-κ β ligand (RANKL) in vitro. We investigated the impact of conditioned medium obtained from human palatine tonsil-derived mesenchymal stem cells (T-CM) on the interactions between osteoclasts and Th17 cells. T-CM effectively blunted the RANK-RANKL interaction between the osteoclast precursor cell line RAW 264.7 and Th17 cells via osteoprotegerin (OPG) activity. The frequency of tartrate-resistant acid phosphatase (TRAP)-positive cells in the bone marrow of an imiquimod (IMQ)-induced psoriasis mouse model was decreased following T-CM injection. Therefore, our data provide novel insight into the therapeutic potential of tonsil-derived mesenchymal stem cell-mediated therapy (via OPG production) for the treatment of pathophysiologic processes induced by osteoclasts under chronic inflammatory conditions such as psoriasis.

Abstract
To investigate the potential role of vitamin D (1,25(OH)2D3) in preventing the development of nasal polyps, we examined the effect of vitamin D on myofibroblast differentiation and extracellular matrix (ECM) production in TGF-β1-induced nasal polyp-derived fibroblasts (NPDFs) and elucidated the mechanisms underlying its inhibitory effect. 1,25(OH)2D3 significantly reduced expression levels of α-SMA, a myofibroblast marker, and fibronectin, a representative ECM component, in a dose-dependent manner in TGF-β1-induced NPDFs. 1,25(OH)2D3 suppressed activated Smad2/3 in time-course. Up-regulation of α-SMA, fibronectin and phosphorylation of Smad2/3 by TGF-β1 was unaffected by 1,25(OH)2D3 in NPDFs after vitamin D receptor-specific siRNA transfection. We confirmed that the Smad2/3-specific inhibitor SIS3 inactivated Smad2/3 and reduced α-SMA and fibronectin expression. Furthermore, acetylation of histone H3 was compromised by 1,25(OH)2D3, leading to inhibition of collagen 1A1, collagen 1A2 and α-SMA gene expression. Treatment with 1,25(OH)2D3 also significantly suppressed TGF-β1-enhanced contractility and motility in a contraction assay and Transwell migration assay. Finally, 1,25(OH)2D3 had a similar effect in ex vivo organ cultures of nasal polyps. Taken together, our results suggest that 1,25(OH)2D3 might be an effective therapy for nasal polyps by reducing myofibroblast differentiation and ECM production mediated by Smad2/3-dependent TGF-β1 signaling pathways in NPDFs.

Abstract
Vitamin D deficiency is effective in the development of acute rhinosinusitis and prolongation of inflammation by increasing inflammation in the sinonasal epithelium. Vitamin D deficiency is important in the development of bone barriers that prevent the complication of acute rhinosinusitis. Although Vitamin D levels may be a variable risk factor for various respiratory tract disorders, there are limited data on the role in sinonasal infections. Our aim was to investigate the association of 25-hydroxy-vitamin D (25OHD) levels with acute rhinosinusitis (ARS) and preseptal cellulitis complications. The type of the study is prospective case-control study. Fifteen patients in the pediatric age group with ARS-induced preseptal cellulitis complication were identified as Group 1, fifteen patients with ARS and without complication were identified as Group 2, and fifteen healthy volunteers were identified as Group 3. Serum 25OHD levels (nmol/l) were measured in addition to routine blood tests at the first admission of patients participating in the study. Statistical analysis was performed between groups. The ages of the cases ranged from 1 to 14 years with a mean of 5.62 ± 3.42 years. 55.6% of the cases (n = 25) were male; 44.4% (n = 20) were female children. As a result of classification in which vitamin D levels were compared with normal values, there was a statistically significant difference according to the presence of ARS (Group-1 and Group 2) and absence of ARS (Group-3) (p < 0.05). A statistically significant difference was also found between Group 1 and Group-3 (p < 0.05). Statistically significant difference between Group 1 and Group 3 suggests that lack of vitamin D predisposes to the complication of preseptal cellulitis. Comparison of Group 1 and 2 with Group 3 (normal subjects) suggests that Vit D has a protective effect against developing sinusitis.

Abstract
BACKGROUND An exciting development in upper respiratory tract disease is the pathophysiology of vitamin D (VD3). There now is substantial literature to indicate that VD3 acts as an immunomodulator of adaptive and innate immunity locally within the respiratory epithelium. Chronic rhinosinusitis (CRS) places a relatively large socioeconomic burden on developed nations, yet remains a difficult disease to treat. VD3, therefore, has become an area of clinical interest because it may provide an adjunctive drug therapy option in CRS, thereby potentially improving the quality of life of these patients. OBJECTIVE A systematic review of the relationship among serum VD3 levels, CRS phenotype, and disease severity by using outcome assessments. METHODS A systematic search was performed by using the PubMed, MEDLINE, and EMBASE databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Studies that measured serum VD3 levels and correlated the measurements to any subtype of CRS (with or without nasal polyps) were included for qualitative analysis. RESULTS Seven articles were included (four prospective and three retrospective studies), with a total of 539 patients. There were significantly lower VD3 levels in the polypoid phenotypes of CRS compared with controls. Low VD3 levels were often associated with an increased degree of inflammation. CONCLUSION The available evidence indicated that there is a significant relationship between low VD3 levels and polypoid CRS phenotypes. The association between VD3 levels and disease severity and VD3 potential for drug therapy remains unclear, which warrants further research in the area.

Abstract
Allergic fungal rhinosinusitis (AFRS) is a unique variety of chronic polypoid rhinosinusitis usually in atopic individuals, characterized by presence of eosinophilic mucin and fungal hyphae in paranasal sinuses without invasion into surrounding mucosa. It has emerged as an important disease involving a large population across the world with geographic variation in incidence and epidemiology. The disease is surrounded by controversies regarding its definition and etiopathogenesis. A working group on "Fungal Sinusitis" under the International Society for Human and Animal Mycology (ISHAM) addressed some of those issues, but many questions remain unanswered. The descriptions of "eosinophilic fungal rhinosinusitis" (EFRS), "eosinophilic mucin rhinosinusitis" (EMRS) and mucosal invasion by hyphae in few patients have increased the problem to delineate the disease. Various hypotheses exist for etiopathogenesis of AFRS with considerable overlap, though recent extensive studies have made certain in depth understanding. The diagnosis of AFRS is a multi-disciplinary approach including the imaging, histopathology, mycology and immunological investigations. Though there is no uniform management protocol for AFRS, surgical clearing of the sinuses with steroid therapy are commonly practiced. The role of antifungal agents, leukotriene antagonists and immunomodulators is still questionable. The present review covers the controversies, recent advances in pathogenesis, diagnosis, and management of AFRS.

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.

Abstract
BACKGROUND Protecting the upper airway from microbial infection is an important function of the immune system. Proper detection of these pathogens is paramount for sinonasal epithelial cells to be able to prepare a defensive response. Toll-like receptors and, more recently, bitter taste receptors and sweet taste receptors have been implicated as sensors able to detect the presence of these pathogens and certain compounds that they secrete. Activation of these receptors also triggers innate immune responses to prevent or counteract infection, including mucociliary clearance and the production and secretion of antimicrobial compounds (e.g., defensins). OBJECTIVE To provide an overview of the current knowledge of the role of innate immunity in the upper airway, the mechanisms by which it is carried out, and its clinical relevance. METHODS A literature review of the existing knowledge of the role of innate immunity in the human sinonasal cavity was performed. RESULTS Clinical and basic science studies have shown that the physical epithelial cell barrier, mucociliary clearance, and antimicrobial compound secretion play pivotal innate immune roles in defending the sinonasal cavity from infection. Clinical findings have also linked dysfunction of these defense mechanisms with diseases, such as chronic rhinosinusitis and cystic fibrosis. Recent discoveries have elucidated the significance of bitter and sweet taste receptors in modulating immune responses in the upper airway. CONCLUSION Numerous innate immune mechanisms seem to work in a concerted fashion to keep the sinonasal cavity free of infection. Understanding sinonasal innate immune function and dysfunction in health and disease has important implications for patients with respiratory ailments, such as chronic rhinosinusitis and cystic fibrosis.

Abstract
Dendritic cells (DCs) are critical in linking the innate and adaptive immune responses, which have been implicated in the pathogenesis of many immune and inflammatory diseases as well as the development of tumours. The role of DCs in the pathophysiology of lung diseases has been widely studied. However, the phenotype, subset and function of DCs in upper airways under physiological or pathological conditions remain largely undefined. Allergic rhinitis (AR) and chronic rhinosinusitis (CRS) are two important upper airway diseases with a high worldwide prevalence. Aberrant innate and adaptive immune responses have been considered to play an important role in the pathogenesis of AR and CRS. To this end, understanding the function of DCs in shaping the immune responses in sinonasal mucosa is critical in exploring the pathogenic mechanisms underlying AR and CRS as well as in developing novel therapeutic strategies. This review summarizes the phenotype, subset, function and regulation of DCs in sinonasal mucosa, particularly in the setting of AR and CRS. Furthermore, this review discusses the perspectives for future research and potential clinical utility focusing on DC pathways in the context of AR and CRS.

Abstract
There are a variety of medical conditions associated with chronic sinonasal inflammation, including chronic rhinosinusitis (CRS) and cystic fibrosis. In particular, CRS can be divided into 2 major subgroups based on whether nasal polyps are present or absent. Unfortunately, clinical treatment strategies for patients with chronic sinonasal inflammation are limited, in part because the underlying mechanisms contributing to disease pathology are heterogeneous and not entirely known. It is hypothesized that alterations in mucociliary clearance, abnormalities in the sinonasal epithelial cell barrier, and tissue remodeling all contribute to the chronic inflammatory and tissue-deforming processes characteristic of CRS. Additionally, the host innate and adaptive immune responses are also significantly activated and might be involved in pathogenesis. Recent advancements in the understanding of CRS pathogenesis are highlighted in this review, with special focus placed on the roles of epithelial cells and the host immune response in patients with cystic fibrosis, CRS without nasal polyps, or CRS with nasal polyps.

Abstract
BACKGROUND Vitamin D3 (VD3) is a steroid hormone with known antiproliferative properties. Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) have been shown to be VD3-deficient. Moreover, VD3 deficiency is associated with worse disease in patients with CRSwNP. One cell type thought to play a role in chronic rhinosinusitis (CRS) is the human sinonasal fibroblast (HSNF). The aim of this study was to investigate VD3 deficiency and HSNF proliferation in CRSwNP. METHODS Blood and sinus tissue explants were collected at the time of surgery from patients with CRSwNP (n = 15). Control subjects (n = 12) were undergoing surgery for cerebrospinal fluid leak repair or to remove non-hormone-secreting pituitary tumors. Ex vivo HSNF proliferation was analyzed with flow cytometry using expression of fibroblast-specific protein (FSP) and the proliferation marker Ki67. Plasma levels of 25-hydroxyvitamin D3 (25VD3) were measured by enzyme-linked immunosorbent assay. In vitro analysis of HSNF proliferation after treatment with calcitriol (1,25VD3) was performed using carboxyfluorescein succinimidyl ester (CFSE) and analyzed with flow cytometry. RESULTS In CRSwNP patients there was an inverse correlation between 25VD3 and proliferating HSNFs (p = 0.0135). This correlation was not seen for control patients (p = 0.3869). In vitro analysis showed that HSNFs from patients with CRSwNP had a higher proliferation index at baseline than HSNFs from control patients (p < 0.01). When treated with 1,25VD3, there was a significant decrease in HSNF proliferation index in patients with CRSwNP (p < 0.01), but not control patients. CONCLUSION VD3 deficiency is associated with increased HSNF proliferation in CRSwNP. Further investigation into how HSNFs and VD3 impact CRSwNP pathophysiology is warranted.

Abstract
OBJECTIVES Skeletal changes among beta (β) thalassemia children are well documented, but without available data regarding sino-nasal passages alterations. The authors investigated the maxillary sinuses and sino-nasal passages changes in β-thalassemia children and correlated such changes with the amount of transfused red cells and the erythroid marrow activity. METHODS Clinical analyses including otorhinolaryngical examination (ORL) were obtained in twenty β-thalassemia children and 20 matched healthy controls. Hemoglobin (Hb), serum ferritin, soluble transferrin receptor (sTfR) levels and bone mineral density of the lumbar spine (BMD ls) were assayed. The two groups were analyzed for the CT image parameters: bone thickness, anterior and posterior choanae diameters, extramedullary hematopoiesis and chronic rhinosinusitis (CRS) RESULTS: Nasal congestion/obstruction was identified in 14 (70%) children. Eight patients (40%) had criteria of chronic rhinosinusitis. In comparison with the normal controls, the increase in the roof, floor, medial, anterior, lateral and posterior maxillary bony walls thickness was significantly higher (1.26, 2.46, 2.6, 2.9, 3.23 and 5.34-folds, respectively). The mean posterior choanae horizontal, vertical diameters and their surface area were significantly reduced in the patients compared to the controls. The mean anterior maxillary wall bone thickness directly correlated with sTfR (P=0.047) while that of the posterior wall correlated inversely with Hb level (P=0.013). The mean vertical posterior choanae diameter had positive correlation with the amount of transfused red cells (P=0.001) and negative correlation with sTfR (P=0.001). The Hounsfield unit of maxillary sinus wall had direct relation with BMDls (P=0.003) CONCLUSIONS: Thalassemia children are at risk of different folds increase of maxillary sinuses walls thicknesses utmost at posterior and lateral walls. Other sino-nasal morbidities include diminished posterior choanal diameter, nasal obstruction and CRS. Certain morbidities had relations to the erythroid marrow activity and the transfusion adequacy.

Abstract
BACKGROUND Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) have deficiencies in circulating and sinonasal levels of the inactive form of vitamin D3, 25-hydroxycholecalciferol (25VD3). Moreover, CRSwNP patients have reduced epithelial cell-specific expression of 1α-hydroxylase; the enzyme responsible for the conversion of 25VD3 to its metabolically active form, 1α,25-dihydroxyvitamin D3 (1,25VD3). The objective of this work was to determine the impact of sinonasal 1α-hydroxylase levels combined from all cellular sources on subjective disease severity and to identify variables influencing its expression. METHODS Blood and sinus tissue explants were collected at the time of surgery from control, chronic rhinosinusitis without nasal polyps (CRSsNP), CRSwNP, and allergic fungal rhinosinusitis (AFRS) patients. 1α-Hydroxylase was measured by immunostaining with flow cytometric analysis. Subjective disease severity was measured by the 22-item Sino-Nasal Outcomes Test (SNOT-22). 1,25VD3 and 25VD3 were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS Patients with CRSwNP or AFRS have reduced 1α-hydroxylase and 1,25VD3 compared to controls or CRSsNP. Circulating 1,25VD3 levels were the same among all groups. No differences in sinonasal 1α-hydroxylase or 1,25VD3 were found between CRSwNP and AFRS. Gender, age, race, atopy, and systemic 25VD3 had no impact on sinonasal 1α-hydroxylase levels in any group. However, CRSwNP patients with asthma had higher 1α-hydroxylase than those without asthma. Total 1α-hydroxylase levels inversely correlated with SNOT-22 in CRSwNP, but not CRSsNP. CONCLUSION Patients with CRSwNP and AFRS both have reduced sinonasal 1α-hydroxylase and 1,25VD3 compared to controls or CRSsNP. Reductions in intracellular 1α-hydroxylase combined from all sinonasal cell types were associated with more severe subjective disease severity in CRSwNP.

Abstract
BACKGROUND Although nasal polyps (NPs) are thought to be a common otorhinolaryngologic disease, there have been few population-based epidemiologic studies on the prevalence of NPs. The aim of this study is to evaluate the prevalence of NPs and the risk factors in the general Korean population. METHODS The data were obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) (2009-2011), which was a cross-sectional survey of noninstitutionalized populations all around the country (n = 28,009). Among them, 19,152 participants (age more than or equal to 20 years) completed medical interviews, physical examinations and endoscopic examination. Analyses were performed using a complex sample design to identify the prevalence and its risk factors. RESULTS The weighted prevalence of NPs was 2.5%. The increased prevalence was associated with increasing age. In the multivariate analyses, male sex [adjusted odds ratio (OR) = 1.68, 95% confidence interval (CI) = 1.25-2.26], low education level (adjusted OR = 1.57, CI = 1.16-2.13), obesity (adjusted OR = 1.49, CI = 1.19-1.87), asthma (adjusted OR = 1.80, CI = 1.24-2.62), and thyroid cancer (adjusted OR = 2.98, CI = 1.26-7.09) were associated with NPs. Among those with NPs, the proportion of symptomatic NPs was 34.4% and asthma was the only significant associated risk factor. CONCLUSION The prevalence of NPs in the Korean general population was not low despite advances in medical and surgical treatment and two thirds of the subjects with NPs were asymptomatic. Further investigation is needed to exhibit the causal relationship between the associated risk factors identified and NPs.

Abstract
Although vitamin D status may be a modifiable risk factor for various respiratory ailments, limited data exists regarding its role in sinonasal infections. Our goal was to investigate the association of 25-hydroxyvitamin D (25OHD) levels with acute rhinosinusitis (ARS) in a large, nationally representative sample of non-institutionalized individuals from the United States. In this cross-sectional study of individuals ≥ 17 years from the National Health and Nutrition Examination Survey 2001-2006, we used multivariable regression analysis to investigate the association of 25OHD levels with ARS, while adjusting for season, demographics (age, sex, race, and poverty-to-income ratio), and clinical data (smoking, asthma, chronic obstructive pulmonary disease, diabetes mellitus, and neutropenia). A total of 3921 individuals were included in our analyses. Median 25OHD level was 22 (interquartile range 16-28) ng/mL. Overall, 15.8% (95% confidence interval [CI] 14.4-17.7) of participants reported ARS within the 24 hours leading up to their survey participation. After adjusting for season, demographics, and clinical data, 25OHD levels were associated with ARS (odds ratio 0.88, 95% CI 0.78-0.99 per 10 ng/mL). When vitamin D status was dichotomized, 25OHD levels < 20 ng/mL were associated with 33% higher odds of ARS (odds ratio 1.33, 95% CI 1.03-1.72) compared with levels ≥ 20 ng/mL. Our analyses suggest that 25OHD levels are inversely associated with ARS. Randomized, controlled trials are warranted to determine the effect of optimizing vitamin D status on the risk of sinonasal infections.

Abstract
Chronic rhinosinusitis (CRS) is a chronic inflammatory disease of the upper airways of which two major phenotypes exist, CRS without nasal polyps (CRSsNP) and CRS with nasal polyps (CRSwNP). Some patients with CRS have suboptimal response to current guideline treatments. These patients remain severe and uncontrolled by treatment and have a poor quality of life. It is highly important to identify both clinical and biological markers, so-called biomarkers, in this subset of patients. The presence of nasal polyps and comorbidity with asthma and with aspirin-exacerbated respiratory disease (AERD) are the most common clinical traits that have been associated to difficult-to-treat severe CRS. In addition to clinical traits, numerous biological markers, with known etiopathogenic roles in CRS, have been associated to difficult-to-treat or recalcitrant CRS. This review summarizes the existing knowledge of the clinical and biological markers associated to difficult-to-treat or uncontrolled severe CRS.

Abstract
BACKGROUND Mounting evidence suggests that Toll-like receptor (TLRs) plays an important role in oxidative stress and is implicated in the pathogenesis of hyperoxic lung injury. 1α,25-Dihydroxyvitamin D3 (1,25(OH)2D3), the hormonally active form of vitamin D, not only plays an essential role in mineral balance, but also possesses immunomodulatory and antioxidant properties. Besides, Vitamin D3 is involved in the regulation of TLRs signaling. The present study was designed to investigate whether 1,25(OH)2D3 attenuates hyperoxia-induced lung injury by regulating TLRs signaling in neonatal rats. METHODS Pups were divided into four groups: normoxia control group (NC), normoxia plus 1,25(OH)2D3 treatment group (ND), hyperoxia control group (HC), and hyperoxia plus 1,25(OH)2D3 treatment group (HD). Lung tissues were collected for histological examination and detection of mRNA and protein expressions. RESULTS Treatment of hyperoxia-exposed animals with 1,25(OH)2D3 resulted in significantly increased body weight and reduced hyperoxia-induced lung injury. Moreover, 1,25(OH)2D3 significantly downregulated the expression of TLR4, NF-κB, and the inflammatory cytokines TNF-α, IL-1β, and IL-6. CONCLUSIONS 1,25(OH)2D3 could attenuate hyperoxia-induced lung injury in neonatal rats, possibly by regulating TLR4/NF-κB signaling.

Abstract
A large number of human, animal and in vitro studies have suggested that vitamin D3 (VD3) plays a critical role in inflammatory airway diseases such as asthma, chronic rhinosinusitis, and allergic rhinitis. VD3 acts upon a broad range of immune cells involved in the pathogenesis of these diseases including T-cells, dendritic cells (DCs), macrophages, and B-cells. In addition, VD3 can also regulate the functions of a number of non-immune cells including epithelial cells, fibroblasts, and smooth muscle cells. Given that VD3 has known effects on the immune system, it seems logical that supplementation with VD3 would prove efficacious in the treatment of these three diseases. While many studies, most of which are observational, have suggested that VD3 deficiency is associated with more severe disease, VD3 supplementation trials in humans have resulted in varied outcomes in terms of efficacy. In this review article we will discuss the role of VD3 in these three commonly associated respiratory diseases. We will explore the literature describing associations of VD3 deficiency with patient outcomes, cells in the respiratory microenvironment susceptible to VD3 regulation, conflicting results of VD3 supplementation trials, and potential gaps in our knowledge that may be limiting the widespread use of VD3 for the treatment of respiratory diseases such asthma, chronic rhinosinusitis and allergic rhinitis. This article is part of a Special Issue entitled '17th Vitamin D Workshop'.

Abstract
BACKGROUND The immunopathogenesis of chronic rhinosinusitis (CRS) is largely unknown, but it is thought that different inflammatory profiles are responsible for the different CRS subtypes. 25-Hydroxyvitamin-D (25-VD3) has been shown to alter inflammatory mediators in other disease processes and 25-VD3 deficiency is associated with CRS with nasal polyps (CRSwNP), but it is unknown if 25-VD3 levels impact local inflammation in CRS. This study investigated the correlation between plasma 25-VD3 and sinonasal mucus monocyte chemoattractant protein-1 (MCP-1), regulated upon activation normal T cell expressed and secreted (RANTES), and basic fibroblast growth factor (bFGF) levels in patients with CRS. METHODS Study subjects undergoing endoscopic sinus surgery (ESS) for CRS were prospectively enrolled from January 2012 to August 2014. Control subjects included patients undergoing ESS for noninflammatory pathology. Blood and sinonasal mucus were collected at the time of ESS. Plasma 25-VD3 was measured by enzyme-linked immunosorbent assay (ELISA) and mucus levels of MCP-1, RANTES, and bFGF by cytometric bead array (CBA). RESULTS A total of 57 patients were enrolled and categorized as CRS without nasal polyps (CRSsNP) (n = 31), CRSwNP (n = 14), and controls (n = 12). No significant correlation was found between MCP-1 and 25-VD3. There was a significant negative correlation between 25-VD3 and RANTES (r = -0.612; p = 0.026) and bFGF (r = -0.578; p = 0.039) in CRSwNP patients; however, there was no significant correlation in CRSsNP patients. CONCLUSION This data suggests that 25-VD3 may play a role in regulation of RANTES and bFGF expression in CRSwNP. This may occur through regulation of NP fibroblasts or other immune cells. Further investigation is warranted to better elucidate the role of RANTES, bFGF, and 25-VD3 in CRSwNP.

Abstract
Diseases of the pediatric nose and nasal sinuses as well as neighboring anatomical structures encompass a variety of pathologies, especially of inflammatory nature. Congenital disease, such as malformations and structural deviations of the nasal septum, as well as systemic metabolic pathologies affecting the nose and sinuses, rarely require medical therapy from an Otolaryngologist. The immunological function of the mucosa and genetic factors play a role in the development of disease in the pediatric upper airway tract, especially due to the constantly changing anatomy in this growth phase. Disease description of the nose and nasal sinuses due to mid-facial growth must also take developmental age differences (infant, toddler, preschool, and school age) into account. Epidemiological examinations and evidence based studies are often lacking in the pediatric population. The wide range of inflammatory diseases of the nose and paranasal sinuses, such as the acute and chronic rhinosinusitis, the allergic rhinitis, and adenoid disease, play a role in the susceptibility of a child to infection. The susceptibility to infection depends on the pediatric age structure (infant, young child) and has yet to be well defined. The acute rhinosinusitis in children develops after a viral infection of the upper airways, also referred to as the "common cold" in the literature. It usually spontaneously heals within ten days without any medical therapy. Antibiotic therapy is prudent in complicated episodes of ARS. The antibiotic therapy is reserved for children with complications or associated disease, such as bronchial asthma and/or chronic bronchitis. A chronic rhinosinusitis is defined as the inflammatory change in the nasal mucosa and nasal sinus mucosa, in which the corresponding symptoms persist for over 12 weeks. The indication for CT-imaging of the nasal sinuses is reserved for cases of chronic rhinosinusitis that have been successfully treated with medication. A staged therapeutic concept is followed in CRS based on conservative and surgical methods. Nasal sinus surgery is considered nowadays as effective and safe in children. Based on the assumption that adenoids are a reservoir for bacteria, from which recurrent infections of the nose and nasal sinus originate, the adenoidectomy is still defined as a cleansing procedure in rhinosinusitis. 69.3% of the children had benefit from adenoidectomy. Comorbidities, such as pediatric bronchial asthma, presently play an even more important role in the therapy of rhinosinusitis; therefore, it is often wise to have the support of pediatricians. In western European countries 40% of children presently suffer from allergic rhinitis, in which pronounced nasal obstruction can cause disturbed growth in facial bones. An early therapy with SIT may prevent the development of bronchial asthma and secondary sensitization to other allergens. Therefore, SIT is recommended in treatment of allergic rhinitis whenever, if possible. The assessment of diagnostic tools is for the examiner not often possible due to the lack of evidence. Rhinosurgical approaches are often described in study reports; however, they lack the standard prospective randomized long-term study design required nowadays and can only be evaluated with caution in the literature.

Abstract
BACKGROUND Vitamin D deficiency is reported to be associated with increased incidence of allergic airway diseases and is correlated with the severity of asthma. This study was designed to determine if serum Vitamin D level is lower in chronic rhinosinusitis with nasal polyposis (CRSwNP) patients and if low serum Vitamin D level is correlated with the severity of CRSwNP. METHODS New CRSwNP patients undergoing elective endoscopic sinus surgery were recruited. Patients with malignancies or asthma were excluded. Twenty chronic rhinosinusitis without nasal polyposis (CRSsNP) patients were used as control. Demographic characteristic information was collected. The severity of CRSwNP was assessed with the Lund-Mackay (LM) score and polyp grading system. Vitamin D status was assessed by measuring circulating 25-hydroxyvitamin D (25OHD) by using commercial chemiluminescence immunoassay. Data were stratified by factors known to affect serum 25OHD, including sex, race, and body mass index. RESULTS Serum 25OHD levels (ng/mL ± SD) were significantly lower in patients with CRSwNP (21.4 ± 5.7) than in those with CRSsNP (28.8 ± 6.2; p < 0.001). The incidences of vitamin D deficiency (<20 ng/mL) in CRSwNP and CRSsNP patients were 45.5 and 6.3%; however, the incidences of vitamin D insufficiency (20-30 ng/mL) in these patients were 50.0 and 62.5%, respectively. A significantly negative relationship was found between serum 25OHD level and polyp grade (r = -0.63; p = 0.001), indicating lower serum 25OHD was associated with higher polyp grade. Serum 25OHD was inversely related to both LM score and total IgE level as well; however, statistical significance was not found. CONCLUSION A significantly lower vitamin D level was found in a group of Taiwanese CRSwNP patients, which revealed an association with greater nasal polyp size. Serum vitamin D levels could be added to the routine workup of patients suffering from CRS and these data could be used to potentially help determine the disease severity.

Abstract
BACKGROUND Cigarette smoke (CS) plays a role in the exacerbation of chronic rhinosinusitis (CRS); however, the mechanism for this is unknown. We hypothesize that CS impairs human sinonasal epithelial cell (HSNEC) conversion of 25(OH)D3 (25VD3) to 1,25-dihydroxyvitamin D3 (1,25VD3) and, furthermore, that supplementation with 1,25VD3 will reverse smoke-induced inflammatory responses by HSNECs. OBJECTIVE We sought to determine the effect of CS on vitamin D3 (VD3) levels, conversion, and regulation of CS-induced inflammation in control subjects and patients with CRS. METHODS Blood and sinus tissue explants were collected at the time of surgery from control subjects, patients with chronic rhinosinusitis without nasal polyps, and patients with chronic sinusitis with nasal polyps (CRSwNP). Expression of VD3 metabolizing enzymes were measured by using RT-PCR. Primary HSNECs were cultured from tissue explants. 25VD3 with and without cigarette smoke extract (CSE) was used to examine conversion of 25VD3 to 1,25VD3, as well as HSNEC production of proinflammatory cytokines. RESULTS CS exposure was associated with reduced circulating and sinonasal 25VD3 levels in all groups compared with those seen in CS-naive, disease-matched counterparts. CS exposure decreased expression of CYP27B1 and was especially pronounced in patients with CRSwNP. CSE impairs control HSNEC conversion of 25VD3. HSNECs from patients with CRSwNP also demonstrate an intrinsic reduction in conversion of 25VD3 to 1,25VD3. Exogenous 1,25VD3 reduces CSE-induced cytokine production by HSNECs. CONCLUSIONS Exposure to CS is associated with reduced 25VD3 levels and an impaired ability of HSNECs to convert 25VD3 to 1,25VD3. Addition of 1,25VD3 reduces the proinflammatory effects of CS on HSNECs. Impaired VD3 conversion by CS exposure represents a novel mechanism through which CS induces its proinflammatory effects.

Abstract
BACKGROUND The objective of this work was to determine if specific chronic rhinosinusitis with nasal polyps (CRSwNP) populations are at risk for vitamin D3 (VD3 ) deficiency and if VD3 levels correlate with radiographic measures of disease severity or eosinophilia. METHODS This study was a retrospective review of an academic rhinology practice. CRSwNP patients who had VD3 levels and CT scan within 6 months of each other were included. CT scans were graded using Lund-Mackay scoring (LMS) and peripheral eosinophil counts were measured. Demographic data including race, gender, age, body mass index, atopic status, and presence of asthma were collected. CRSwNP was subdivided into allergic fungal rhinosinusitis (AFRS), aspirin-exacerbated respiratory disease (AERD), and other CRSwNP. Multivariate analysis was performed to examine correlations and control for confounding factors. RESULTS Insufficient VD3 levels were found in 55% of all CRSwNP patients. VD3 correlated with African American race because nearly 80% of all African Americans had insufficient VD3 levels. Lower VD3 levels also correlated with more severe mucosal disease on CT scans as measured by LMS. There was no correlation between VD3 levels and age, gender, body mass index, atopy, asthma, or CRSwNP subtype. CONCLUSION VD3 insufficiency/deficiency is common in CRSwNP patients, especially those of African American race. Lower levels of VD3 are associated with worse LMS on CT. The role of VD3 in CRSwNP warrants further investigation.

Abstract
INTRODUCTION Monocyte-derived dendritic cells (moDCs) are antigen-presenting cells capable of directing immune responses toward T-helper 1 (Th1) or T-helper 2 (Th2) phenotypes. The systemic profile of moDCs and their association with Th1/Th2 skewing in chronic rhinosinusitis (CRS) is unclear. The purpose of this study is to characterize circulating moDCs in controls, CRS without nasal polyps (CRSsNP), and CRS with nasal polyps (CRSwNP) and correlate moDCs with Th1/Th2 skewing, mucosal inflammation on computed tomography (CT), and quality of life (QoL). STUDY DESIGN Cross-sectional study. SETTING Tertiary care hospital. SUBJECTS Blood was drawn from control (n = 12), CRSsNP (n = 18), and CRSwNP (n = 15) patients during endoscopic sinus surgery. METHODS Peripheral blood moDCs were analyzed with flow cytometry for expression of HLA-DR, CD209, and CD14. Th1 and Th2 cells were identified by CXCR3 and CCR8 expression, respectively. Lund-Mackay CT scores were assigned by blinded graders. Sino-Nasal Outcome Test 22 (SNOT-22) surveys were completed by patients before surgery. RESULTS CRSsNP and CRSwNP displayed elevations in systemic moDCs compared with controls. In CRSwNP, systemic Th2 skewing was observed and circulating CD4+ Th2 cells correlated with percent moDCs. MoDCs strongly correlated with higher Lund-Mackay CT scores in CRSsNP but not in CRSwNP. No relationship between moDCs and SNOT-22 scores was observed for either subset of CRS. CONCLUSION These data support that CRSwNP and CRSsNP display alterations in systemic immune profiles. CRSwNP is characterized by significant elevations in circulating moDCs, which is associated with systemic Th2-biased inflammation. Circulating moDCs are associated with mucosal inflammation on CT imaging in CRSsNP. No association between moDCs and QoL is evident in either CRS subset.

Abstract
OBJECTIVE To investigate the association between serum 25-hydroxyvitamin D [25(OH)D] level and history of community-acquired pneumonia (CAP). PATIENTS AND METHODS We identified 16,975 individuals (≥17 years) from the third National Health and Nutrition Examination Survey (NHANES III) with documented 25(OH)D levels. To investigate the association of 25(OH)D with history of CAP in these participants, we developed a multivariable logistic regression model, adjusting for demographic factors (age, sex, race, poverty-to-income ratio, and geographic location), clinical data (body mass index, smoking status, asthma, chronic obstructive pulmonary disease, congestive heart failure, diabetes mellitus, stroke, chronic kidney disease, neutropenia, and alcohol consumption), and season. Locally weighted scatterplot smoothing (LOWESS) was used to depict the relationship between increasing 25(OH)D levels and the cumulative frequency of CAP in the study cohort. RESULTS The median [interquartile range (IQR)] serum 25(OH)D level was 24 (IQR 18-32) ng/mL. 2.1% [95% confidence interval (CI): 1.9-2.3] of participants reported experiencing a CAP within one year of their participation in the national survey. After adjusting for demographic factors, clinical data, and season, 25(OH)D levels <30 ng/mL were associated with 56% higher odds of CAP [odds ratio 1.56; 95% confidence interval: 1.17-2.07] compared to levels ≥30 ng/mL. LOWESS analysis revealed a near linear relationship between vitamin D status and the cumulative frequency of CAP up to 25(OH)D levels around 30 ng/mL. CONCLUSION Among 16,975 participants in NHANES III, 25(OH)D levels were inversely associated with history of CAP. Randomized controlled trials are warranted to determine the effect of optimizing vitamin D status on the risk of CAP.

Abstract
PURPOSE OF REVIEW Allergic rhinitis, chronic rhinosinusitis (CRS) and asthma have a high worldwide prevalence and confer a significant socioeconomic burden. This article reviews the recent advances in allergic rhinitis, CRS and asthma with view to understanding the upper and lower airway as one system. RECENT FINDINGS Allergic rhinitis, CRS and asthma demonstrate strong epidemiological coassociation, and early life risk factors for upper airway disease are now apparent. The absence of demonstrable peripheral IgE does not strictly classify airway disease as nonallergic. Excess mucosal inflammation with immune dysregulation is a common feature to all. An important role for innate immunity is now apparent and offers prospects of novel therapeutic approaches in the future. A role for bacterial superantigens is also emerging in all three diseases. Genetic studies highlight common associations between allergic rhinitis, CRS and asthma. SUMMARY Whether such overlapping pathological findings reflect a manifestation of the same disease but in relation to the different airway locations in individuals with genetic predisposition remains unknown, although likely. This continues under investigation and debate. The current research priorities are to understand what key events predispose to both upper and lower airway disease together and the critical immunological factors that establish and sustain airway inflammation.

Abstract
INTRODUCTION Nasal polyps are smooth outgrowths assuming a shape of grapes, formed from the nasal mucosa, limiting air flow by projecting into a lumen of a nasal cavity. Up to now the surgical resection is the best method of their treatment, but etiology and pathogenesis of the nasal polyps is not yet fully established. AIM OF THE STUDY The aim of the study was the assessment of the selected lysosomal exoglycosidases activity in the nasal polyps. In this study the activity of β-galactosidase, α-mannosidase and α-fucosidase was determined in the tissue of the nasal polyps obtained from 40 patients (10F, 30M) and control tissues derived from mucosa of lower nasal conchas obtained during mucotomy from 20 patients (10F, 10M). RESULTS We observed significant lower values of GAL, FUC and tendency to decrease of MAN and GLU concentration in nasal polyps (P) in comparison to control healthy nasal mucosa (C). In nasal polyp tissue (P) no differences of GAL, MAN and FUC specific activity in comparison to control mucosa (C) were found. CONCLUSIONS Our research supports bioelectrical theory of the nasal polyps pathogenesis and directs attention at research on glycoconjugates and glycosidases of the nasal mucosa extracellular matrix.

Vitamin D regulation of OX40 ligand in immune responses to Aspergillus fumigatus. Infect Immun 2013; 81:1510-9.

Abstract
OX40 ligand (OX40L) is a costimulatory molecule involved in Th2 allergic responses. It has been shown that vitamin D deficiency is associated with increased OX40L expression in peripheral CD11c(+) cells and controls Th2 responses to Aspergillus fumigatus in vitro in cystic fibrosis (CF) patients with allergic bronchopulmonary aspergillosis (ABPA). To investigate if vitamin D deficiency regulated OX40L and Th2 responses in vivo, we examined the effect of nutritional vitamin D deficiency on costimulatory molecules in CD11c(+) cells and A. fumigatus-induced Th2 responses. Vitamin D-deficient mice showed increased expression of OX40L on lung CD11c(+) cells, and OX40L was critical for enhanced Th2 responses to A. fumigatus in vivo. In in vitro assays, vitamin D treatment led to vitamin D receptor (VDR) binding in the promoter region of OX40L and significantly decreased the promoter activity of the OX40L promoter. In addition, vitamin D altered NF-κB p50 binding in the OX40L promoter that may be responsible for repression of OX40L expression. These data show that vitamin D can act directly on OX40L, which impacts Th2 responses and supports the therapeutic use of vitamin D in diseases regulated by OX40L.
