Abstract
Combined allergic rhinitis and asthma syndrome (CARAS) is an airway-type 2 immune response with a profuse inflammatory process widely affecting the world population. Due to the compromise of quality of life and the lack of specific pharmacotherapy, the search for new molecules becomes relevant. This study aimed to evaluate the effectiveness of the Morita-Bailys-Hillman adduct (CISACN) treatment in the CARAS experimental model. Female BALB/c mice were ovalbumin (OVA) -sensitized and -challenged and treated with CISACN. The treatment decreased the eosinophil migration to the nasal and lung cavities and tissues and the goblet cell hyperplasia/hypertrophy, attenuated airway hyperactivity by reducing the hyperplasia/hypertrophy of the smooth muscle and the extracellular matrix's thickness. Also, the treatment reduced the clinical signs of rhinitis as nasal rubbing and sneezing in a histamine-induced nasal hyperreactivity assay. The immunomodulatory effect of CISACN was by reducing OVA-specific IgE serum level, and IL-33, IL-4, IL-13, and TGF-β production, dependent on IFN-γ increase. Furthermore, the effect of CISACN on lung granulocytes was by decreasing the p-p38MAPK/p65NF-κB signaling pathway. Indeed, CISACN reduced the p38MAPK and p65NF-κB activation. These data demonstrated the anti-inflammatory and immunomodulatory effects of the CISACN with scientific support to become a pharmacological tool to treat airway inflammatory diseases.

Clinical Remission of Asthma and Allergic Rhinitis - in a Longitudinal Population Study. J Asthma Allergy 2022; 15:1569-1578. [PMID: 36387839 PMCID: PMC9643071 DOI: 10.2147/jaa.s378584] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Accepted: 10/14/2022] [Indexed: 10/01/2023] Open
Abstract
BACKGROUND Although asthma and allergic rhinitis are chronic diseases, some patients experience periods of remission. Information on prognostic factors associated with the remission of asthma and allergic rhinitis is valuable in resource prioritization. This study investigated factors associated with the clinical remission of asthma and allergic rhinitis. METHODS In the Respiratory Health In Northern Europe (RHINE) study, data was collected with questionnaires in stage one (RHINE I, 1989-1992) and two follow-ups (RHINE II, 1999-2001 and RHINE III, 2010-2012) from Sweden, Norway, Denmark, Iceland and Estonia. Clinical remission was defined as having reported asthma or allergic rhinitis in RHINE I or RHINE II but not in RHINE III. RESULTS Of 13,052 participants, 975 (7.5%) reported asthma in RHINE I or RHINE II, and 3379 (25.9%) allergic rhinitis. Clinical remission of asthma and allergic rhinitis was found in 46.4% and 31.8%, respectively. Living in Estonia (OR (95% CI) 2.44 (1.22-4.85)) and living in an apartment (1.45 (1.06-1.98)) were related to remission of asthma, while subjects reporting allergic rhinitis (0.68 (0.51-0.90)), asthma onset ≤ 12 years of age (0.49 (0.35-0.68)), receiving treatment with antibiotics for respiratory illness (0.64 (0.47-0.87)) were less likely to have asthma remission. Factors related to a higher likelihood of remission of allergic rhinitis were no asthma at baseline, age ≥ 58 years in RHINE III, allergic rhinitis onset after 12 years of age, living in rural areas as a child, having only a primary school education and not being pregnant. CONCLUSION Clinical remission was found in almost one-half of those with asthma and one-third of persons with allergic rhinitis. Coexisting allergic symptoms were associated with less clinical asthma remission. Age, asthma symptoms and environmental factors in childhood, such as living in a rural area, were found to influence the clinical remission of allergic rhinitis.

Allergen-specific immunotherapy induces the suppressive secretoglobin 1A1 in cells of the lower airways. Allergy 2021; 76:2461-2474. [PMID: 33528894 DOI: 10.1111/all.14756] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 12/29/2020] [Accepted: 01/03/2021] [Indexed: 01/02/2023]
Abstract
BACKGROUND While several systemic immunomodulatory effects of allergen-specific immunotherapy (AIT) have been discovered, local anti-inflammatory mechanisms in the respiratory tract are largely unknown. We sought to elucidate local and epithelial mechanisms underlying allergen-specific immunotherapy in a genome-wide approach. METHODS We induced sputum in hay fever patients and healthy controls during the pollen peak season and stratified patients by effective allergen immunotherapy or as untreated. Sputum was directly processed after induction and subjected to whole transcriptome RNA microarray analysis. Nasal secretions were analyzed for Secretoglobin1A1 (SCGB1A1) and IL-24 protein levels in an additional validation cohort at three defined time points during the 3-year course of AIT. Subsequently, RNA was extracted and subjected to an array-based whole transcriptome analysis. RESULTS Allergen-specific immunotherapy inhibited pro-inflammatory CXCL8, IL24, and CCL26mRNA expression, while SCGB1A1, IL7, CCL5, CCL23, and WNT5BmRNAs were induced independently of the asthma status and allergen season. In our validation cohort, local increase of SCGB1A1 occurred concomitantly with the reduction of local IL-24 in upper airways during the course of AIT. Additionally, SCGB1A1 was identified as a suppressor of epithelial gene expression. CONCLUSIONS Allergen-specific immunotherapy induces a yet unknown local gene expression footprint in the lower airways that on one hand appears to be a result of multiple regulatory pathways and on the other hand reveals SCGB1A1 as novel anti-inflammatory mediator of long-term allergen-specific therapeutic intervention in the local environment.

Inhibition of TRPA1 reduces airway inflammation and hyperresponsiveness in mice with allergic rhinitis. FASEB J 2021; 35:e21428. [PMID: 33774861 DOI: 10.1096/fj.201902627r] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 12/18/2020] [Accepted: 01/22/2021] [Indexed: 12/26/2022]
Abstract
This study was conducted to investigate whether a transient receptor potential ankyrin 1 (TRPA1) antagonist (HC-030031) can reduce airway inflammation and hyperresponsiveness in a murine allergic rhinitis (AR) model. BALB/c mice were sensitized and challenged by ovalbumin (OVA) to induce AR. HC-030031 or vehicle was administrated to mice via intraperitoneal injection prior to OVA challenges. Nose-scratching events, histopathologic alterations of the airways, and bronchial hyperresponsiveness (BHR) were assessed. Differential cells and proinflammatory cytokines in the nasal lavage (NAL) and bronchoalveolar lavage (BAL) fluid were measured. Expressions of TRPA1 in nasal mucosa were examined by immunohistochemistry. TRPA1-expressing vagal neurons were labeled by immunofluorescent staining. HC-030031-treated AR mice had markedly reduced type-2 inflammation in nasal mucosa and ameliorated-nose-scratching events than AR mice received vehicle. HC-030031 treatment also dramatically reduced leucocyte numbers and IL-8 level in the BAL fluid, inhibited lower airway remodeling and fibrosis, and nearly abolished BHR. HC-0300031 treatment significantly inhibited the upregulated number of TRPA1 expressing nasal epithelial cells and TRPA1 expressing sensory neurons, leading to downregulation of SP in both upper and lower airways. Targeting TRPA1 may represent a promising strategy for treating AR and AR-related asthma.

[PMID: 32529476 DOI: 10.1007/s00011-020-01368-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 05/12/2020] [Accepted: 05/23/2020] [Indexed: 12/31/2022] Open
Abstract
OBJECTIVES Allergic rhinitis (AR) is a chronic inflammatory disease of nasal mucosa. Loss of function of Th17 cells and regulatory T (Treg) cells plays a role in the pathogenesis of AR. IL18, FOXP3, and IL13 are key genes in the development of AR. However, the genetic associations between IL18, FOXP3 and IL13 genes polymorphisms and AR risk were inconclusive yet. METHODS A meta-analysis was performed by searching through Pubmed, EMBASE, web of science and CNKI databases. The ORs and 95%CIs were used to assess the genetic association between the allelic, dominant and recessive models of IL18, FOXP3 and IL13 genes polymorphisms and AR risk. RESULTS A total of 15 articles (6 for FOXP3, 5 for IL18, and 5 for IL13) were enrolled in the present study. No association was detected between the IL18 rs187238, rs1946518, rs360721, FOXP3 rs2232365, rs3761548 and IL13 rs1800925 polymorphisms and AR risk (p > 0.05). Significant associations were observed between the allelic (p = 0.001, OR 1.32, 95% CI 1.12-1.56), dominant (p = 0.005, OR 1.43, 95% CI 1.11-1.83) and recessive models (p = 0.01, OR 1.64, 95% CI 1.13, 2.40) of IL13 rs20541 and AR risk. Subgroup analysis based on ethnicity revealed that the IL13 rs20541 was significantly associated with AR risk in Asian population (allelic model: p = 0.009, OR 1.36, 95% CI 1.13-1.63, dominant model: p = 0.005, OR 1.43, 95% CI 1.11-1.83; recessive model: p = 0.01, OR 1.64, 95% CI 1.13-2.40). CONCLUSIONS IL13 rs20541 may contribute to the risk of AR in Asian population. To confirm these results, larger number of case-control study with more subjects is necessary in the future.

Allergic Rhinitis in Rats Is Associated with an Inflammatory Response of the Hippocampus. Behav Neurol 2018; 2018:8750464.

Abstract
Allergic rhinitis (AR) is a major concern in personal and public health, which negatively affects emotions and behavior, leading to cognitive deficits, memory decline, poor school performance, anxiety, and depression. Several cellular and molecular mediators are released in the inflammatory process of AR and activate common neuroimmune mechanisms, involving emotionally relevant circuits and the induction of anxiety. Responsiveness of the hypothalamic-pituitary-adrenal (HPA) axis to allergic processes have been reported, which may also include responsiveness of the hippocampus, cortex, and other brain regions. Here, we have used an optimized rat model of AR to explore whether the disease has a relationship with inflammatory responses in the hippocampus. AR was established in adult rats by ovalbumin sensitization, and the expression of various inflammatory substances in the hippocampus was measured by specific assays. Comparison between experimental and various control groups of animals revealed an association of AR with significant upregulation of substance P, microglia surface antigen (CD11b), glial fibrillary acid protein (GFAP), tumor necrosis factor-α (TNF-α), and interleukin 6 (IL-6) in the hippocampus. Thus, we hypothesize that the AR challenge may activate these inflammatory mediators in the hippocampus, which in turn contribute to the abnormal behavior and neurological deficits associated with AR.

Abstract
PURPOSE Thymic stromal lymphopoietin (TSLP) is a critical regulator of immune responses associated with Th2 cytokine-mediated inflammation. Intranasal administration of oligodeoxynucleotides with CpG motifs (CpG-ODNs) might improve lower airway outcomes of combined allergic rhinitis and asthma syndrome (CARAS), but the inherent mechanisms of CpG-ODNs are not well defined. This study investigated whether CpG-ODNs treated to upper airway could reduce lower airway TSLP expression as well as whether this reduction could contribute to the alleviation of lower allergic inflammation and airway hyper-reactivity (AHR) in CARAS mice. MATERIALS AND METHODS Ovalbumin (OVA)-sensitized BALB/c mice were intranasal OVA exposure three times a week for 3 weeks. CpG-ODNs or an anti-TSLP mAb was administered to a subset of these mice 1 hour after intranasal OVA challenge, followed by 5 days of OVA aerosol challenge. The resulting immunological variables, nasal symptoms, and nasal mucosa and lung tissues pathology were evaluated. TSLP production in the lung tissues and bronchoalveolar lavage fluid (BALF) were determined by RT-PCR, western blotting or enzyme-linked immunosorbent assay. RESULTS The CARAS mice exhibited overexpression of TSLP in the lung tissues and BALF, and also demonstrated significant increases in BALF and splenocyte Th2-associated cytokine production, serum OVA-specific IgE, nose and lung pathologies, and AHR. Intranasal administration of CpG-ODNs restored TSLP in the lower airway, and it significantly reduced the following parameters: Th2-type cytokine production levels; the percentage of eosinophils in the BALF; IL-4 and IL-5 concentrations in the supernatants of cultured splenic lymphocytes; serum OVA-specific IgE; peribronchial inflammation score in the lungs; and nose pathology and nasal symptoms. Similar results were obtained when the CARAS mice were treated with an anti-TSLP mAb to block intranasal TSLP activity. CONCLUSIONS Treatment with intranasal CpG-ODNs improves lower airway immunological variable outcomes in the CARAS model via a mechanism that possibly involves in suppressing pulmonary TSLP-triggered allergic inflammation.

Abstract
OBJECTIVE Sleep disordered breathing (SDB) has not been well studied in urban adolescents with asthma in community settings. Nor has the association of SDB symptoms and asthma severity been studied. We characterized self-reported symptoms suggesting SDB and investigated the association of SDB symptoms, probable asthma, and asthma severity. METHODS 9,565 adolescents from 21 inner-city high schools were screened for an asthma intervention study. Students reported on symptoms suggesting SDB using questions from the 2007 NHANES, if they were ever diagnosed with asthma, and on asthma symptoms. Using generalized linear mixed models with logit link with school as a random intercept and adjusting for age, gender, and race/ethnicity, we examined associations of SDB symptoms, and demographic characteristics, probable asthma, and asthma severity. RESULTS 12% reported SDB symptoms. Older and bi-racial participants (compared to Caucasian) had higher odds of symptoms suggesting SDB (p <.001). Compared to those without probable asthma, adolescents with probable asthma had 2.63 greater odds of reporting SDB symptoms (p <.001). Among those with probable asthma, the odds of reporting SDB symptoms increased with asthma severity. When exploring daytime severity and severity due to night wakening separately, results were similar. All results remained significant when controlling for age, gender, and ethnicity. CONCLUSIONS In a large urban community cohort of predominately ethnic minority adolescents, self-reported SDB symptoms were associated with probable asthma and increased asthma severity. This study highlights the importance of SDB as a modifiable co-morbidity of asthma.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is a recurrent, benign, extensively proliferating disease that is triggered by inflammation. The signaling pathways in sinusitis and the regulation by intracellular signaling peptides and proteins are not fully understood. Signal transducer and activator of transcription (STAT) 5a and STAT5b are two closely related phosphokinases involved in the regulation of diverse cellular functions, including proliferation and apoptosis. OBJECTIVE The objective of the study was to investigate the expression, activation, and distribution of STAT5 Transcription factor in CRSwNP. METHODS We studied these transcription factors in tissue samples of nasal polyps and inferior turbinates from a total of 35 patients with CRSwNP and compared them with healthy nasal mucosa. The samples were analyzed by using a DNA microarray, quantitative real-time polymerase chain reaction, a protein array, immunoblot, immunoprecipitation and immunohistochemistry. RESULTS We found equivalent overall expression of STAT5a in all tissue types. We observed an increase in the expression of STAT5b protein in both polyps and turbinates of patients with CRSwNP. In addition, STAT5b, but not STAT5a, was activated by phosphorylation in nasal polyps. Phosphorylated STAT5a/b was not detectable in the epithelium of turbinates from either patients with CRSwNP or patients with healthy mucosa, but it was clearly expressed in the epithelium of nasal polyps. CONCLUSION Analysis of these data indicates distinct expression and activation of STAT5a and STAT5b in nasal polyps, particularly the activation of STAT5b. It is possible that STAT5b may contribute to the development of nasal polyps.

Intranasal administration of CpG oligodeoxynucleotides reduces lower airway inflammation in a murine model of combined allergic rhinitis and asthma syndrome. Int Immunopharmacol 2015; 28:390-8. [PMID: 26163938 DOI: 10.1016/j.intimp.2015.06.028] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2015] [Revised: 06/20/2015] [Accepted: 06/22/2015] [Indexed: 01/18/2023]
Abstract
Given the relationship between allergic rhinitis (AR) and asthma, it can be hypothesized that reducing upper airway inflammation by targeting oligodeoxynucleotides with CpG motifs (CpG-ODN) specifically to the upper airway via intranasal administration in a small volume (10 μL) might improve lower airway (asthma) outcomes. The goal of this study was to investigate the therapeutic efficacy of 10 μL of intranasal versus intradermal administration of CpG-ODN in suppressing lower airway inflammation and methacholine-induced airway hyperreactivity (AHR) in mice subjected to ovalbumin (OVA)-induced combined allergic rhinitis and asthma syndrome (CARAS). OVA-sensitized BALB/c mice were subjected to upper-airway intranasal OVA exposure three times per week for 3 weeks. Then, CpG-ODN was administered to a subset of these mice 1h after intranasal OVA exposure, followed by five days of OVA aerosol challenges, thereby targeting OVA to the lower airways. Immunologic variables and nasal symptoms were evaluated. The results showed that the CARAS mice exhibited significant increases in bronchoalveolar lavage fluid (BALF) and splenocytes Th2-associated cytokine production, OVA-specific serum IgE, and AHR, as well as nose and lung pathologies. Intranasal administration of CpG-ODN significantly reduced Th2-associated cytokine production, the percentage of eosinophils in the BALF, the IL-4 and IL-5 concentrations in the supernatants of cultured OVA-challenged splenic lymphocytes, the serum OVA-specific IgE levels, the peribronchial inflammation score in the lungs, and the severity of nose pathology and nasal symptoms. However, intradermal administration of CpG-ODN did not significantly reduce the aforementioned parameters. In conclusion, intranasal treatment with CpG-ODN attenuated AR and significantly alleviated lower airway inflammation and AHR in the CARAS model. CpG-ODN therapy was more effective when administered intranasally than when administered intradermally. The current study supports the development of CpG-ODN nasal spray as a novel therapeutic agent for CARAS.

Abstract
Chronic mucosal inflammation is the hallmark of important and common airway diseases, such as allergic rhinitis (AR) and asthma. Lipoxin A4 (LXA4) is an endogenous pro-resolving mediator for mucosal inflammation that decreases allergic and asthmatic responses. Lipoxin B4 (LXB4) is a structurally distinct member of the lipoxin family that signals in a manner distinct from LXA4. LXB4 is generated by mucosal tissues, but its actions in allergic inflammation are unknown. Here, we used murine models of AR and asthma to investigate LXB4's activity in mucosal inflammation. In the upper airway, LXB4 significantly decreased nasal mucosal leukocytes and degranulation of mast cells (MCs) and eosinophils. In the lower airway, LXB4 significantly decreased airway inflammation, mucus metaplasia, and hyper-responsiveness. Inhibition of MC degranulation in vivo by LXB4 was more potent than dexamethasone, and these agents displayed unique profiles for cytokine regulation; however, their overall anti-inflammatory actions were comparable. LXB4 decreased eotaxin-dependent eosinophil chemotaxis, IgE-mediated MC degranulation, and expression of type 2 cytokine receptors. Together, these findings indicate that LXB4 carries cell type selective and mucosal protective actions that broaden the lipoxin family's therapeutic potential for upper and lower airway catabasis.

Abstract
BACKGROUND Sinus disease is commonly seen in patients with asthma, and several studies have been published describing the relationship between sinus disease and the inflammation seen in the sputum of asthmatic subjects. In this article, we expand on this knowledge by studying patients with eosinophilic bronchitis with and without asthma. METHODS We describe the relationship between the severity of sinus disease determined by the Lund-Mackay score and sputum eosinophilia. Comparisons with blood eosinophil and total immunoglobulin (IgE) measurements are made. RESULTS We have shown that the severity of sinus disease is positively correlated with sputum eosinophil counts, and the site of sinus disease affected the level of eosinophilia. There was a positive correlation between sputum eosinophils and blood eosinophils, but there was no relationship with blood total IgE levels. CONCLUSIONS We have confirmed that there is a link between upper and lower airway inflammation and that this is not limited to patients with asthma. The process is associated with systemic inflammation as evidenced by increased blood eosinophils but appears to be independent of IgE.

Abstract
PURPOSE Extensive data support the influence of the upper airway on lower airway inflammation and pathophysiology in allergic disease. However, few studies have focused on allergic inflammation in the nose after an isolated lower airway allergen challenge, a situation that can exist clinically when human subjects breathe primarily through the mouth, as occurs when nasally congested. This study used a mouse model to investigate whether upper airway inflammation and hyperresponsiveness were induced by an isolated lower airway allergen challenge. METHODS BALB/c mice were sensitized by systemic intraperitoneal injection of ovalbumin/saline and challenged with intratracheal ovalbumin/saline. Inflammation in the nose and lungs was assessed by cytology and histology of nasal tissues and bronchoalveolar lavage fluid (BALF), while nasal airway resistance and response were measured over 3 days post-challenge. RESULTS Intratracheal application of an allergen in anaesthetized mice resulted in exclusive deposition in the lower airway. Compared to control animals, ovalbumin-sensitized mice after challenge showed bronchial hyperreactivity and increased IL-5 in the serum BALF, as well as eosinophil infiltration in the lungs. However, nasal histology of the ovalbumin-sensitized mice showed no increase in eosinophil infiltration. The nasal lavage fluid revealed no increase in eosinophils or IL-5, and the nasal airway resistance did not increase after challenge either. CONCLUSIONS In a mouse allergy model, exclusive allergen challenge of the lower airway can elicit a pulmonary and systemic allergic response, but does not induce upper airway inflammatory or physiological responses.

Abstract
CONCLUSION Early intervention may change the natural course of allergic rhinitis, preventing the progression to asthma. In particular, immunotherapy guarantees remission of local symptoms and valid protection against local and bronchial complications. Symptomatic treatment represents a valid alternative; it is always to be preferred to abstention from any treatment. OBJECTIVES Data emerging from various studies on the increase of the prevalence of allergic rhinitis in recent decades appear to be widely dishomogeneous. Another point that needs clarification is the relationship between allergic rhinitis and lower airways pathologies such as asthma or bronchitis. METHODS We followed the evolution of allergic rhinitis in a group of patients for the last 30 years to highlight the efficacy of different treatments in the prevention of complications, specifically asthma. After 32 years (1980-2012), 46/73 (63%) patients completed the follow-up. RESULTS Symptomatic drugs exhibited maximum efficacy from the third to the eighth year, with 13 of 15 patients reporting an improvement of symptoms; immunotherapy achieved the best efficacy starting from the sixth to the tenth year (8 of 10 patients recovered). Subsequently, improvements decreased in the two groups, to a steady level of 11 of 15 and 6 of 10 recovered patients. Asthma developed in 3 of 46 patients and only among patients that were not treated.

Abstract
BACKGROUND Oral tolerance (OT) is considered as a preventive and therapeutic strategy for treating asthma and allergic rhinitis (AR). We investigated the preventive effects of OT on allergic inflammation and remodeling in the upper and lower airways in a mouse model of allergy. METHODS BALB/c mice were divided into four groups: control, allergy, low-dose OT, and high-dose OT. To induce OT, mice were fed ovalbumin (OVA) before sensitization with OVA/Al(OH)(3) at a dose of 1 mg for 6 days in low-dose OT group and a single dose of 25 mg in high-dose OT group. After sensitization followed by OVA challenge, nasal symptoms, interleukin (IL)-13, interferon (IFN)-gamma, IL-10, and transforming growth factor (TGF) beta-1 levels in nasal lavage (NAL) and bronchoalveolar lavage (BAL) fluids were measured, and OVA-specific IgE, IgG1, and IgG2a levels were measured in the serum. The airway hyperresponsiveness (AHR) was measured by enhanced pause. The goblet cell hyperplasia and the thickness of lamina propria were observed in the upper and lower airways. RESULTS In the allergy group, the allergic behavior scores, AHR, and OVA-specific IgE, IgG1, and IgG2a levels; inflammatory cells; IFN-gamma levels; and IL-13 levels in NAL/BAL fluids were elevated compared with the control group, low-dose OT group, and high-dose OT group. The allergy group had higher levels of IL-10 and TGF-beta-1 in BAL fluids when compared with the other groups. The goblet cell hyperplasia and the thickness of the lamina propria were attenuated in both OT groups compared with the allergy group. CONCLUSION OT may effectively prevent AHR, allergic inflammation, and airway remodeling in the upper and lower airways.

Abstract
BACKGROUND Nasal obstruction is a very common symptom in children. The main causes are allergic rhinitis (AR) and adenoidal hypertrophy (AH); the possible correlation between AR and AH has been investigated by few studies, mainly conducted using radiographic craniometry. This study aimed at investigating this topic by nasal endoscopy. METHODS There were 205 children (134 boys; mean age, 6.7 years age range, 4-12 years) studied. Clinical visit, nasal endoscopy, and skin-prick test were performed in all patients. Anterior nasal obstruction was graded using the Friedmann's classification. Adenoid size was graded using the Parikh's classification. Perception of symptoms by children was also assessed using the visual analog scale. RESULTS Ninety-two children (44.9%) had complete nasal obstruction and 28 children (13.7%) had choanae invasion. There was a negative significant correlation (r = -0.41; p < 0.001) between nose obstruction severity and volume of adenoids. Decreased probability of greater adenoid volume was associated with increased severity of nose obstruction (odds ratio [OR] = 0.13) and in patients with allergy compared with nonallergic patients (OR = 0.31). CONCLUSION This real-life study shows that large adenoids may be associated with absence of allergy, whereas large turbinates may be associated with small adenoids.

Abstract
BACKGROUND Allergic rhinitis (AR) and asthma are 2 entities of allergic airway diseases that frequently occur together, which is referred to as united airways. In contrast to this general concept, we hypothesized that innate immunity of the upper and lower airways is respectively distinctive, because the immunologic conditions of the nasal and lung mucosa as well as the functions of the immune cells within their epithelia are different. OBJECTIVE We wanted to identify distinctive mechanisms of innate immunity in the nose and lung mucosa, which are responsible for house dust mite (HDM)-induced AR and allergic asthma (AA), respectively. METHODS We constructed a mouse model of AR or AA induced by sensitization and consequent provocation with HDM extracts. RESULTS HDM-derived β-glucans, rather than LPS, were proven to be essential to activating innate immunity in the nasal mucosa and triggering AR, which depended on Toll-like receptor 2 (TLR2), but not on TLR4; however, the LPS/TLR4 signaling axis, rather than β-glucans/TLR2, was critical to HDM-induced AA. These differences were attributed to the specific role of β-glucans and LPS in inducing the surface expression of TLR2 and TLR4 and their translocation to lipid rafts in nasal and bronchial epithelial cells, respectively. We also showed that dual oxidase 2-generated reactive oxygen species mediate both β-glucan-induced TLR2 activation and LPS-induced TLR4 activation. CONCLUSIONS We describe a novel finding of distinctive innate immunity of the nose and lungs, respectively, which trigger AR and AA, by showing the critical role of HDM-induced TLR activation via dual oxidase 2-mediated reactive oxygen species.

Abstract
Bamboo salt (BS) is a specially processed salt according to the traditional recipe using sun-dried salt (SDS) and bamboo in Korea. The present study investigated the effects and mechanism of BS, SDS, NaCl, or mineral mixture (containing zinc, magnesium, and potassium) on ovalbumin (OVA)-induced allergic rhinitis (AR) animal model. The increased number of rubs was inhibited by the oral administration of BS, SDS, NaCl, mineral mixture, or nose inhalation of BS. The increased levels of IgE, histamine, and interleukin (IL)-1β in serum were reduced by BS. The level of interferon-γ was increased, whereas the level of IL-4 was reduced on the spleen tissue of BS-treated mice. In the BS-treated mice, the number of eosinophils and mast cells infiltration increased by OVA-sensitization were also decreased. Protein levels of inflammatory cytokines were reduced by BS or NaCl administration in the nasal mucosa of the AR mice. In addition, BS inhibited caspase-1 activity in the nasal mucosa tissue. In activated human mast cells, BS significantly inhibited the production of IL-1β and thymic stromal lymphopoietin and activation of caspase-1. Our data indicate that BS has anti-allergic and anti-inflammatory effects by regulating of caspase-1 activation in AR mice and in vitro models.

Abstract
BACKGROUND Th17 cell lineage, a distinct pro-inflammatory lineage characterized by preferential synthesis of cytokines IL-17A and IL-17F, is thought to play an important role in the pathogenesis of allergic rhinitis (AR). OBJECTIVES Our aim was to investigate whether polymorphisms in and around IL-17A and IL-17F genes are associated with AR and comorbid asthma. METHODS A case-control comparison was performed in a cohort of 279 AR patients, 197 allergic rhinitis with asthma (AR-A) patients and 281 control Chinese subjects, to investigate associations between 19 tagging single-nucleotide polymorphisms (SNPs) in IL-17A and IL-17F gene regions and manifestation of AR or AR-A. Genotyping was performed using the Sequenom MassARRAY platform. RESULTS SNP rs3819024 in IL-17A gene, intergenic SNPs rs1892280 and rs10807439 were specifically associated with AR protective or risk effects, while rs3819024 in IL-17A gene, intergenic SNP rs13192563 in IL-17F gene were associated with AR-A protective or risk effects. Haplotype analysis showed significant AR risk in haplotype AA (rs1892280G-rs13192563A) and AR protective effect in haplotype GT (rs7758579A-rs11966760T); the haplotype AT(rs7758579-rs11966760) were considered AR-A risk. CONCLUSIONS Our findings preliminarily indicate IL17A and IL17F SNPs, and some intergenic variants have the potential association with AR and comorbid asthma in Chinese population.

Abstract
RATIONALE Allergic rhinitis and exercise induced bronchoconstriction (EIB) are common in asthmatic children. The aim of this study was to investigate whether treatment of allergic rhinitis with an intranasal corticosteroid protects against EIB in asthmatic children. METHODS This was a double-blind, randomized, placebo-controlled, parallel group study. Subjects aged 12-17 years, with mild-to-moderate asthma, intermittent allergic rhinitis and ≥ 10% fall in FEV(1) at a screening exercise challenge were randomized to 22 ± 3 days treatment with intranasal fluticasone furoate or placebo. The primary outcome was change in exercise induced fall in FEV(1) . Secondary outcomes were changes in the area under the curve (AUC), asthma control questionnaire (ACQ), pediatric asthma quality of life questionnaire (PAQLQ), and exhaled nitric oxide (FeNO). RESULTS Twenty-five children completed the study. Mean exercise induced fall in FEV(1) (± SD) decreased significantly (95% CI: 0.7-18.2%, P = 0.04) in the fluticasone furoate group from 28.4 ± 15.8% to 19.0 ± 13.8%, compared to the placebo group (27.4 ± 16.0% to 27.4 ± 19.2%). The change in AUC was not significantly different between treatment groups. However, within the fluticasone furoate group the AUC decreased significantly (P = 0.01). Although total PAQLQ score did not improve, the activity limitation domain score improved significantly within the fluticasone furoate group (P = 0.03). No significant changes were observed in FeNO and ACQ. CONCLUSION Treatment of allergic rhinitis in asthmatic children with an intranasal corticosteroid reduces EIB and tends to improve quality of life.
