Int Forum Allergy Rhinol 2014; 4:43-8. [PMID: 24574125 DOI: 10.1002/alr.21239] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2013] [Revised: 08/24/2013] [Accepted: 06/18/2013] [Indexed: 11/10/2022]
Abstract
BACKGROUND We investigated whether nebulization of budesonide via a NasoNeb® device would treat perennial allergic rhinitis. METHODS We performed a parallel, randomized, double-blind, placebo-controlled, pilot study in subjects (n = 40) with perennial allergic rhinitis. After recording baseline symptoms, subjects were randomized to budesonide respules (0.25 mg) or an equivalent placebo for 26 days. Nasal peak inspiratory flow (NPIF) and nasal symptoms (graded on a 0–3 scale) were recorded by the subjects twice daily. Rhinoconjunctivitis quality of life (RQOL) as well as nasal volume, measured by acoustic rhinometry, was obtained at baseline, after 2 weeks, and at the end of treatment. RESULTS The average change from baseline in symptoms over the treatment period was greater for the group on budesonide (−3.33) compared to placebo (−1.98) (p = 0.45). When the average change from baseline over the treatment period was compared between the groups, budesonide resulted in higher NPIF (36.4 L/min) than placebo (18.7 L/min), p = 0.094. QOL improved in both groups compared to baseline with no significant difference between the groups. Although acoustic rhinometry indicated a larger volume in the group treated with budesonide on the last trial visit, the differences between the groups were not significant when accounting for the baseline values. CONCLUSION Compared to placebo, administration of nebulized budesonide in subjects with perennial allergic rhinitis resulted in improvements in symptoms and objective measures of nasal congestion which approached but did not achieve statistical significance. A higher dose of active agent, a less effective placebo and a larger number of subjects might have improved statistical significance.

Abstract
BACKGROUND Little is known about exposure to mouse allergen (Mus m 1) and allergic rhinitis (AR). OBJECTIVE To evaluate the association between mouse allergen exposure and AR in children. METHODS We examined the relation between mouse allergen level in house dust and AR in 511 children aged 6 to 14 years in San Juan, Puerto Rico. Study participants were chosen from randomly selected households using a multistage probability sample design. The study protocol included questionnaires, allergy skin testing, and collection of blood and dust samples. AR was defined as current rhinitis symptoms and skin test reactivity to at least one allergen. RESULTS In the multivariate analyses, mouse allergen level was associated with a 25% decreased odds of AR in participating children (95% confidence interval, 0.62-0.92). Although endotoxin and mouse allergen levels were significantly correlated (r = 0.184, P < .001), the observed inverse association between Mus m 1 and AR was not explained by levels of endotoxin or other markers of microbial or fungal exposure (peptidoglycan and glucan). CONCLUSION Mouse allergen exposure is associated with decreased odds of AR in Puerto Rican school-aged children.

Abstract
Occasional rhinitis symptoms caused by exposure to pollution or allergens is a growing concern. Based first on empirical observation of a lesser occurrence of allergies in quail farmers and then scientific works on ovomucoids properties, we developed a dietary supplement for the relief of such occasional rhinitis symptoms. The objective of the study was to determine whether one acute oral dose of the study product attenuates nasal provocation and other allergy-related symptoms after exposure to a standardized allergenic challenge as compared to placebo. Healthy subjects were recruited to participate in a randomized, double-blind, two-arm crossover, placebo-controlled, clinical trial. One acute dose of either the active study product (proprietary blend of quail egg) or placebo was given concomitantly to the standardized allergenic challenge. The primary endpoint was peak nasal inspiratory flow (PNIF) measurement and the secondary endpoints were subjects' perceived feelings of well-being based on Visual Analog Scale (VAS) scores for allergy-related symptoms, as well as immunoglobulin E count. Forty-three healthy subjects were enrolled and evaluable in a per protocol analysis. A gradual increase in PNIF from nadir up to Time 120 reflected the normal, gradual recovery from nasal obstruction induced by allergenic challenge for both the active and the placebo groups. At all postchallenge time points, the active group had higher PNIF values compared to the placebo group, indicating that the active product was associated with fewer symptoms and reduced intensity of these symptoms. The active product resulted also in statistically significant improvements of most of the subjects' perceived feelings of well-being based on VAS scores. No adverse events occurred during the study. In conclusion, the dietary supplement consisting of proprietary blend made of quail eggs provides fast and efficient relief of allergic rhinitis symptoms caused by the most common outdoor and indoor allergens, without adverse events.

Abstract
Background Interleukin-10 (IL-10) has an important anti-inflammatory and immunoregulatory function, and its expression is negatively correlated with the development and severity of allergic rhinitis (AR). However, the in vivo effects of exogenous IL-10 on AR have not been studied and the mechanisms underlying the effects of IL-10 have not been fully understood. Here, we investigated the effects of intranasal administration of recombinant mouse (rm) IL-10 on the expression of Th responses and local IL-10 in a mouse model of AR induced by ovalbumin. Results Administration of rmIL-10 during challenge significantly reduced the number of eosinophils and mast cells, as well as Type 2 helper T (Th2) and Th17 cell related cytokine and transcription factor levels in the nasal mucosa and nasal lavage fluid in AR mice. The rmIL-10 treatment significantly inhibited the number of IL-10-positive cells and IL-10 mRNA expression in the nasal mucosa in AR mice. Conclusion Our results show that exogenous IL-10 administrated in challenge phase alleviates nasal allergic inflammation in AR mice, most likely by inhibiting Th2 and Th17 responses. It can also inhibit local IL-10 levels in the nasal mucosa. Our findings indicate that IL-10 may have the potential as an inhibitor of AR.

Abstract
BACKGROUND A predominant Th17 population is a marker of allergic rhinitis (AR). As a ligand-activated transcription factor, the aryl hydrocarbon receptor (AhR) plays a vital role in promoting or inhibiting the development of specific Th cells. However, its role in AR remains undefined. OBJECTIVE To analyze the potential role of AhR in the pathogenesis of AR. METHODS In total, 30 AR patients and 13 healthy controls were recruited for this study and AR patients had clinical features, as demonstrated by rhinoconjunctivitis quality of life questionnaires, total symptom scores and visual analog scale scores. The expression of AhR, IL-17 and IL-22 and the presence of Th17 cells in peripheral blood mononuclear cells were measured before and after treatment with the nontoxic AhR ligand 2-(1'H-indole-3'-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE). RESULTS Pretreatment ITE studies revealed that all AR patients had a significant increase in AhR expression compared with controls and AhR expression positively correlated with clinical parameters. After ITE intervention, a severe reduction in the differentiation of Th17 cells and the production of IL-17 and IL-22 was noted in both AR patients and normal subjects. Simultaneously, a dramatic enhancement of AhR expression was also observed in all healthy controls, but not in AR patients. CONCLUSION The results suggested that the AhR may be one of the mechanisms underlying the Th17 response during the pathogenesis of AR and AhR levels were closely related to clinical severity in all AR patients. Additionally, ITE may represent a new drug candidate in the treatment of AR.

Peripheral erythrocytes decrease upon specific respiratory challenge with grass pollen allergen in sensitized mice and in human subjects. PLoS One 2014; 9:e86701.

Abstract
BACKGROUND AND AIMS Specific hyper-responsiveness towards an allergen and non-specific airway hyperreactivity both impair quality of life in patients with respiratory allergic diseases. We aimed to investigate cellular responses following specific and non-specific airway challenges locally and systemically in i) sensitized BALB/c mice challenged with grass pollen allergen Phl p 5, and in ii) grass pollen sensitized allergic rhinitis subjects undergoing specific airway challenge in the Vienna Challenge Chamber (VCC). METHODS AND RESULTS BALB/c mice (n = 20) were intraperitoneally immunized with grass pollen allergen Phl p 5 and afterwards aerosol challenged with either the specific allergen Phl p 5 (n = 10) or the non-specific antigen ovalbumin (OVA) (n = 10). A protocol for inducing allergic asthma as well as allergic rhinitis, according to the united airway concept, was used. Both groups of exposed mice showed significantly reduced physical activity after airway challenge. Specific airway challenge further resulted in goblet cell hyperplasia, enhanced mucous secretion, intrapulmonary leukocyte infiltration and lymphoid follicle formation, associated with significant expression of IL-4, IL-5 and IL-13 in splenocytes and also partially in lung tissue. Concerning circulating blood cell dynamics, we observed a significant drop of erythrocyte counts, hemoglobin and hematocrit levels in both mouse groups, challenged with allergen or OVA. A significant decrease in circulating erythrocytes and hematocrit levels after airway challenges with grass pollen allergen was also found in grass pollen sensitized human rhinitis subjects (n = 42) at the VCC. The effects on peripheral leukocyte counts in mice and humans however were opposed, possibly due to the different primary inflammation sites. CONCLUSION Our data revealed that, besides significant leukocyte dynamics, particularly erythrocytes are involved in acute hypersensitivity reactions to respiratory allergens. A rapid recruitment of erythrocytes to the lungs to compensate for hypoxia is a possible explanation for these findings.

Abstract
Pentaherb formula (PHF) has been proven to improve the quality of life of children with atopic dermatitis without side effects. The aim of this study was to elucidate the potential anti-inflammatory and anti-allergic activities of PHF, Moutan Cortex (Danpi/DP) and gallic acid (GA) using human basophils (KU812 cells), which are crucial effector cells in allergic inflammation. PHF, DP and GA could significantly suppress the expression of allergic inflammatory cytokine IL-33-upregulated intercellular adhesion molecule (ICAM)-1, and the release of chemokines CCL2, CCL5, CXCL8 and inflammatory cytokine IL-6 from KU812 cells (all p < 0.05). With the combined use of dexamethasone (0.01 μg/mL) and GA (10 μg/mL), the suppression of ICAM-1 expression and CCL5 and IL-6 release of IL-33-activated KU812 cells were significantly greater than the use of GA alone (all p < 0.05). The suppression of the IL-33-induced activation of intracellular signalling molecules p38 mitogen activated protein kinase, nuclear factor-kB and c-Jun amino-terminal kinase in GA-treated KU812 cells could be the underlying mechanism for the suppression on ICAM-1, chemokines and cytokines. The combined use of dexamethasone with the natural products PHF or DP or GA might therefore enhance the development of a novel therapeutic modality for allergic inflammatory diseases with high potency and fewer side effects.
