    1982-01-01

    Allergic rhinitis is the result of an immediate hypersensitivity immune response of the nasal mucosa to one or more allergens. Clinical features may be indistinguishable from non-allergic rhinitis. Accurate diagnosis demands specialized laboratory investigations, meticulous history and careful physical examination. Management includes control of allergen and irritant exposures, pharmacotherapy and immunotherapy. Recent development of intranasal corticosteroid aerosols has significantly reduced morbidity. Modified allergens for immunotherapy show promise but require further study. PMID:21286562

    Allergic rhinitis is a common disorder that is strongly linked to asthma and conjunctivitis. It is usually a long-standing condition that often goes undetected in the primary-care setting. The classic symptoms of the disorder are nasal congestion, nasal itch, rhinorrhea and sneezing. A thorough history, physical examination and allergen skin testing are important for establishing the diagnosis of allergic rhinitis. Second-generation oral antihistamines and intranasal corticosteroids are the mainstay of treatment. Allergen immunotherapy is an effective immune-modulating treatment that should be recommended if pharmacologic therapy for allergic rhinitis is not effective or is not tolerated. This article provides an overview of the pathophysiology, diagnosis, and appropriate management of this disorder. PMID:22166009

    Allergic rhinitis is the most common chronic childhood disease. Reduced quality of life is frequently caused by this IgE-mediated disease, including sleep disturbance with subsequent decreased school performance. Asthma and exercise-induced bronchospasm are commonly seen concurrently with allergic rhinitis, and poorly controlled allergic rhinitis negatively affects asthma outcomes. Nonsedating antihistamines or intranasal azelastine are effective agents to manage allergic rhinitis, often in combination with oral decongestants. For moderate to severe persistent disease, intranasal corticosteroids are the most effiective agents. Some patients require concomitant intranasal corticosteroids and nonsedating antihistamines for optimal management. Other available agents include leukotriene receptor antagonists, intranasal cromolyn, intranasal ipratropium, specific immunotherapy, and anti-IgE therapy. PMID:23118635

    This review focuses on local allergic rhinitis, a new phenotype of allergic rhinitis, commonly misdiagnosed as nonallergic rhinitis. It has gained attention over last decade and can affect patients from all countries, ethnic groups and ages, impairing their quality of life, and is frequently associated with conjunctivitis and asthma. Diagnosis is based on clinical history, the demonstration of a positive response to nasal allergen provocation test and/or the detection of nasal sIgE. A positive basophil activation test may support the diagnosis. Recent studies have demonstrated that allergen immunotherapy is an effective immune-modifying treatment, highlighting the importance of early diagnosis.

    Ozone exposure in man produces changes in respiratory function and symptoms. There is a large degree of unexplained intersubject variability in the magnitude of these responses. There is concern that individuals with chronic respiratory diseases may also be more responsive to ozone than normal individuals. The purpose of this study was to describe the responses of subjects with allergic rhinitis to ozone exposure and to compare these responses to those previously observed in normal individuals. A further purpose was to measure the association of baseline nonspecific airway reactivity with changes in lung function and respiratory symptoms following ozone exposure. A group of 26 nonasthmatic subjects with allergic rhinitis performed a bronchial inhalation challenge with histamine and subsequently underwent two hour exposures to both clean air and to 0.18 part per million ozone with alternating periods of rest and heavy exercise. The airway reactivity of this group of subjects was no greater than that of a comparable group of subjects without allergic rhinitis. The respiratory responses of these subjects to ozone exposure were similar to those previously reported for subjects without allergic rhinitis with the exception that the allergic rhinitis subjects appeared to have a modestly increased bronchoconstrictor response compared to normals. Furthermore, we observed no significant relationships between nonspecific airway reactivity and response to ozone as measured by changes in lung function or the induction of symptoms.

    Previous published results have revealed that Rhinolight(®) intranasal phototherapy is safe and effective in intermittent allergic rhinitis. The present objective was to assess whether phototherapy is also safe and effective in persistent allergic rhinitis. Thirty-four patients with persistent allergic rhinitis were randomized into two groups; twenty-five subjects completed the study. The Rhinolight(®) group was treated with a combination of UV-B, UV-A, and high-intensity visible light, while the placebo group received low-intensity visible white light intranasal phototherapy on a total of 13 occasions in 6 weeks. The assessment was based on the diary of symptoms, nasal inspiratory peak flow, quantitative smell threshold, mucociliary transport function, and ICAM-1 expression of the epithelial cells. All nasal symptom scores and nasal inspiratory peak flow measurements improved significantly in the Rhinolight(®) group relative to the placebo group and this finding persisted after 4 weeks of follow-up. The smell and mucociliary functions did not change significantly in either group. The number of ICAM-1 positive cells decreased non-significantly in the Rhinolight(®) group. No severe side-effects were reported during the treatment period. These results suggest that Rhinolight(®) treatment is safe and effective in persistent allergic rhinitis.

    In this paper, we review the current management of allergic rhinitis and new directions for future treatment. Currently, management includes pharmacotherapy, allergen avoidance and possibly immunotherapy. The simple washing of nasal cavities using isotonic saline provides a significant improvement and is useful, particularly in children. The most effective medication in persistent rhinitis used singly is topical corticosteroid, which decreases all symptoms, including ocular ones. Antihistamines reduce nasal itch, sneeze and rhinorrhea and can be used orally or topically. When intranasal antihistamine is used together with topical corticosteroid, the combination is more effective and acts more rapidly than either drug used alone. Alternative therapies, such as homeopathy, acupuncture and intranasal carbon dioxide, or devices such nasal air filters or intranasal cellulose, have produced some positive results in small trials but are not recommended by Allergic Rhinitis and its Impact on Asthma (ARIA). In the field of allergic immunotherapy, subcutaneous and sublingual routes are currently used, the former being perhaps more efficient and the latter safer. Sublingual tablets are now available. Their efficacy compared to standard routes needs to be evaluated. Efforts have been made to develop more effective and simpler immunotherapy by modifying allergens and developing alternative routes. Standard allergen avoidance procedures used alone do not provide positive results. A comprehensive, multi-trigger, multi-component approach is needed, including avoidance of pollutants such as cigarette smoke.

  11. Rhinitis: Allergic and Non-Allergic

    PubMed Central

    Ogrady, M.J.

    1987-01-01

    Rhinitis, or the “stuffy nose”, can be allergic or non-allergic in nature. Accurate diagnosis depends on a well-taken history and physical examination. Non-allergic rhinitis is characterized by absent elevation in allergen-specific IgE. Treatment is based, if possible, on the etiology. Surgical procedures on the turbinates are often needed to allow improvement. Allergic rhinitis is characterized by an increase in allergen-specific IgE. Treatment may involve environmental control, pharmocologic agents, or, finally, immunotherapy. Successful treatment requires accurate assessment of the offending agent and proper use of the above-mentioned modalities. PMID:21263880

    Asthma and allergic rhinitis are common health problems that cause major illness and disability worldwide. The prevalence of allergic rhinitis is estimated to range from 10% to 20% in the USA and Europe. Multiple factors contribute to the wide range of reported prevalence rates. These include type of prevalence rate reported (current or cumulative), study selection criteria, age of participants, differences in survey methods, varied geographic locations and socioeconomic status, any of which are significant enough to confound direct comparison between studies. There is no standard set of diagnostic criteria for allergic rhinitis. In most studies, the criteria for diagnosis are based on the subject's reporting, solely by questionnaire and rarely confirmed by skin testing. In addition, most studies focus on hay fever, leaving perennial allergic rhinitis underestimated. Sinus imaging is generally not performed and, therefore, rhinosinusitis not differentiated. Some investigators report 'current' prevalence while others report 'cumulative' or 'lifetime' prevalence. Epidemiologic studies have consistently shown that asthma and rhinitis often coexist in the same patients. The prevalence of asthma is <2% in subjects without rhinitis while it varies from 10% to 40% in patients with rhinitis. Furthermore, the majority of patients with asthma experience rhinitis, which is a factor in the risk for asthma. Despite recognition that allergic rhinitis and asthma are global health problems, there are insufficient epidemiologic data and more data are needed with regard to their etiologic risk factors and natural history. This aim of this review is to enable the reader to discuss prevalence, risk factors and prognosis of allergic rhinitis and asthma.

    The safety of loratadine (second-generation antihistamine) and montelukast (leukotriene receptor antagonist) as monotherapies is well documented. Safety of the fixed-dose, single-tablet therapy loratadine/montelukast (L/M; SCH 445761, containing loratadine [10 mg]/montelukast [10 mg]), for treatment of the symptoms of allergic rhinitis in >3800 subjects is described. Safety data from 19 randomized clinical studies in which subjects were administered L/M are presented. Adverse events (AEs) were defined as any unfavorable and unintended sign, symptom, or laboratory data, including onset of new illness and exacerbation of preexisting conditions. Only AEs with an onset during the treatment period (i.e., treatment emergent) are summarized. Safety was also assessed via clinical laboratory evaluations and monitoring of vital signs and electrocardiogram (ECG). Overall, the incidence of AEs reported with L/M in the 19 studies was low and comparable with placebo, loratadine monotherapy, and montelukast monotherapy. The most frequently reported AE across all studies was headache. Most AEs were not severe and the duration of such events was short lived. Three AEs (headache [4.5%], fatigue [1.2%], and pharyngolaryngeal pain [1.2%]), regardless of relation to treatment, were reported by >1% of subjects in the L/M treatment group of multiple-dose, placebo-controlled studies. There were no clinically significant changes in clinical laboratory analyses or in vital signs, physical findings, or ECG found to be clinically relevant. Administration of the fixed-dose, single-tablet formulation of L/M was well tolerated. In these clinical studies, the safety of L/M was comparable with placebo, loratadine, and montelukast.

    Background Fungal spores are the predominant biological particulate in the atmosphere of Puerto Rico, yet their potential as allergens has not been studied in subjects with respiratory allergies. The purpose of this study was to determine the level of sensitization of subjects with respiratory allergies to these particles. Methods Serum samples were drawn from 33 subjects with asthma, allergic rhinitis, or nonallergic rhinitis and 2 controls with different skin prick test reactivity. An MK-3 sampler was used to collect air samples and the reactivity of the sera to fungal particles was detected with a halogen immunoassay. Results All subjects reacted to at least 1 fungal particle. Thirty-one subjects reacted to ascospores, 29 to basidiospores, 19 to hyphae/fungal fragments, and 12 to mitospores. The median percentage of haloes in allergic rhinitis subjects was 4.82% while asthma or nonallergic rhinitis subjects had values of 1.09 and 0.39%, respectively. Subjects with skin prick tests positive to 3, 2, 1, or no extract had 5.24, 1.09, 1.61, and, 0.57% of haloed particles, respectively. If skin prick tests were positive to basidiomycetes, pollen, animals, or deuteromycetes, the percentages of haloes were 4.72, 4.15, 3.63, and 3.31%, respectively. Of all haloed particles, 46% were unidentified, 25% ascospores, 20% basidiospores, 7% hyphae/fungal fragments, and 2% mitospores. IgE levels and the number of positive skin prick test extracts correlated with the percentage of haloes. Conclusion In tropical environments, sensitization to airborne basidiomycetes, ascomycetes, and fungal fragments seems to be more prevalent than sensitization to mitospores in subjects with active allergies, suggesting a possible role in exacerbations of respiratory allergies.

    2008-01-01

    Background TNFα may contribute to the pathophysiology of airway inflammation. For example, we have recently shown that nasal administration of TNFα produces late phase co-appearance of granulocyte and plasma exudation markers on the mucosal surface. The objective of the present study was to examine indices of granulocyte presence and activity in response to intranasal TNFα challenge. Methods Healthy subjects and patients with allergic rhinitis (examined out of season) were subjected to nasal challenge with TNFα (10 μg) in a sham-controlled and crossover design. Nasal lavages were carried out prior to and 24 hours post challenge. Nasal biopsies were obtained post challenge. Nasal lavage fluid levels of myeloperoxidase (MPO) and eosinophil cationic protein (ECP) were analyzed as indices of neutrophil and eosinophil activity. Moreover, IL-8 and α2-macroglobulin were analyzed as markers of pro-inflammatory cytokine production and plasma exudation. Nasal biopsy numbers of neutrophils and eosinophils were monitored. Results Nasal lavage fluid levels of MPO recorded 24 hours post TNFα challenge were increased in healthy subjects (p = 0.0081) and in patients with allergic rhinitis (p = 0.0081) (c.f. sham challenge). Similarly, α2-macroglobulin was increased in healthy subjects (p = 0.014) and in patients with allergic rhinitis (p = 0.0034). Lavage fluid levels of ECP and IL-8 were not affected by TNFα challenge. TNFα increased the numbers of subepithelial neutrophils (p = 0.0021), but not the numbers of eosinophils. Conclusion TNFα produces a nasal inflammatory response in humans that is characterised by late phase (i.e., 24 hours post challenge) neutrophil activity and plasma exudation. PMID:18234086

    PubMed Central

    Allergic inflammation of the nasal mucous membranes, like other atopic disorders, occurs primarily as the result of an antigenantibody reaction between external allergens and circulating skin-sensitizing antibodies. In addition, the disease process is frequently complicated by bacterial or viral infection. Effective treatment of allergic rhinitis, therefore, consists of: (1) changing the patient's environment in order to remove the offending allergens, (2) removing the patient from his environment, (3) altering the patient's response to environmental allergens by means of hyposensitization injections, (4) suppressing the allergic reaction with drugs, and (5) eliminating bacterial infection. Usually more than one of these therapeutic measures is required for the individual patient. PMID:14175878

    The prevalence of allergic rhinitis (AR) has been estimated at 10% to 40%, and its economic burden is substantial. AR patients develop specific immunoglobulin E (IgE) antibody responses to indoor and outdoor environmental allergens with exposure over time. These specific IgE antibodies bind to high-affinity IgE receptors on mast cells and basophils. Key outcome measures of therapeutic interventions include rhinitis symptom control, rescue medication requirements, and quality-of-life measures. A comprehensive multiple modality treatment plan customized to the individual patient can optimize outcomes.

    OBJECTIVE: To review new treatments for allergic rhinitis. QUALITY OF EVIDENCE: Most studies supporting the principles in this paper are double-blind, placebo-controlled trials. Good evidence supports use of antihistamines, nasal steroid sprays, and immunotherapy. Fewer trials have been done on the new antileukotrienes. MAIN MESSAGE: Allergic rhinitis causes significant morbidity, which can be successfully treated. Newer antihistamines, developed to replace terfenadine and astemizole which have potential side effects, include loratadine, cetirizine, and the newest, fexofenadine. Intranasal steroid sprays are also effective, particularly for people with nasal stuffiness. One study showed some growth retardation in children using beclomethasone over a prolonged period (1 year). The newer steroid sprays, such as fluticasone, budesonide, and mometasone furoate aqueous, however, have not been studied in the same way and are usually recommended for shorter periods. The newest group of medications showing real promise are the antileukotrienes, including zafirlukast and montelukast. Taken orally, these medications avoid the discomfort of nasal sprays and seem to have few side effects. Immunotherapy offers a new option: a short-course, preseasonal series of six to 11 injections that reduces the burden on patients for year-round therapy. Combinations of these therapies are also possible. CONCLUSIONS: With new medications and immunotherapy options, family physicians can offer effective treatment to patients with allergic rhinitis.

    Topical medications have dramatically changed the treatment of rhinitis. While systemic treatment is often more potent, topical treatment has fewer side effects. However, topical preparations also have side effects which should be considered when treating rhinitis. Topical steroids are potent anti-inflammatories but may cause nasal bleeding; sodium cromoglycate improves allergic and general inflammation but is less potent than steroids. Topical decongestants are beneficial for short-term use when there is nasal obstruction or copious discharge, but can cause damage to nasal epithelium or atrophy and dryness of the nasal mucous membrane after years of use. Anticholinergic spray is effective when watery discharge predominates, and saline is helpful when there is nasal dryness. Treatment of associated conjunctivitis is also discussed. PMID:21286563

    Like asthma and atopic dermatitis, allergic rhinitis is an allergic disease, but of the three, it is the only type I allergic disease. Allergic rhinitis includes pollinosis, which is intractable and reduces quality of life (QOL) when it becomes severe. A guideline is needed to understand allergic rhinitis and to use this knowledge to develop a treatment plan. In Japan, the first guideline was prepared after a symposium held by the Japanese Society of Allergology in 1993. The current 8th edition was published in 2016, and is widely used today. To incorporate evidence based medicine (EBM) introduced from abroad, the most recent collection of evidence/literature was supplemented to the Practical Guideline for the Management of Allergic Rhinitis in Japan 2016. The revised guideline includes assessment of diagnosis/treatment and prescriptions for children and pregnant women, for broad clinical applications. An evidence-based step-by-step strategy for treatment is also described. In addition, the QOL concept and cost benefit analyses are also addressed. Along with Allergic Rhinitis and its Impact of Asthma (ARIA), this guideline is widely used for various clinical purposes, such as measures for patients with sinusitis, childhood allergic rhinitis, oral allergy syndrome, and anaphylaxis and for pregnant women. A Q&A section regarding allergic rhinitis in Japan was added to the end of this guideline.

    Over the last 20 years, there has been significant progress in our understanding of the pathophysiology of allergic rhinitis, including the discovery of new inflammatory mediators, the link between asthma and allergic rhinitis ('one airway-one disease' concept) and the introduction of novel therapeutic modalities. These new insights have been documented in the Allergic Rhinitis and its Impact on Asthma guidelines and have led to the creation of evidence-based management algorithms. We now understand the importance of a common strategy for treating allergic inflammation of the upper and lower airway as a way of improving outcome, reducing hospital admissions, providing better quality of life and perhaps, altering the natural course of the 'allergic march'. A therapeutic ladder is suggested: Whereas for mild intermittent allergic rhinitis, allergen avoidance should be the first line of treatment with subsequent addition of a second generation topical or oral antihistamine, nasal saline or cromoglycate, in cases of moderate to severe allergic rhinitis, a nasal steroid is the treatment of choice. If a patient with moderate/severe persistent allergic rhinitis fails to improve after 4 wk of adequate treatment, patient compliance or the diagnosis must be re-assessed. In such cases, when the diagnosis is in doubt, a careful clinical examination including nasal endoscopy is mandatory to assess for other potential causes of nasal obstruction. In children who suffer from concomitant allergic rhinitis and asthma, a management algorithm that addresses concurrently asthma and allergic rhinitis is vital, both from a theoretical and from a practical point of view: Parents overwhelmingly prefer a single strategy for the treatment of their child's upper and lower airway symptoms; however, the overall quality of life in children with severe asthma can be significantly improved if rhinitis is adequately addressed.

    Rhinitis is a global problem and is defined as the presence of at least one of the following: congestion, rhinorrhea, sneezing, nasal itching, and nasal obstruction. The two major classifications are allergic and nonallergic rhinitis (NAR). Allergic rhinitis occurs when an allergen is the trigger for the nasal symptoms. NAR is when obstruction and rhinorrhea occurs in relation to nonallergic, noninfectious triggers such as change in the weather, exposure to caustic odors or cigarette smoke, barometric pressure differences, etc. There is a lack of concomitant allergic disease, determined by negative skin prick test for relevant allergens and/or negative allergen-specific antibody tests. Both are highly prevalent diseases that have a significant economic burden on society and negative impact on patient quality of life. Treatment of allergic rhinitis includes allergen avoidance, antihistamines (oral and intranasal), intranasal corticosteroids, intranasal cromones, leukotriene receptor antagonists, and immunotherapy. Occasional systemic corticosteroids and decongestants (oral and topical) are also used. NAR has 8 major subtypes which includes nonallergic rhinopathy (previously known as vasomotor rhinitis), nonallergic rhinitis with eosinophilia, atrophic rhinitis, senile rhinitis, gustatory rhinitis, drug-induced rhinitis, hormonal-induced rhinitis, and cerebral spinal fluid leak. The mainstay of treatment for NAR are intranasal corticosteroids. Topical antihistamines have also been found to be efficacious. Topical anticholinergics such as ipratropium bromide (0.03%) nasal spray are effective in treating rhinorrhea symptoms. Adjunct therapy includes decongestants and nasal saline. Investigational therapies in the treatment of NAR discussed include capsaicin, silver nitrate, and acupuncture. PMID:21738880

    The allergic rhinitis is the most common immune disorder with a lifetime prevalence of 24% and one of the most common chronic diseases at all--with tendency to rise. It occurs in childhood and influences the patients' social life, school performance and labour productivity. Furthermore the allergic rhinitis is accompanied by a lot of comorbidities, including conjunctivitis, asthma bronchiale, food allergy, neurodermatitis and sinusitis. For example the risk for asthma is 3.2-fold higher for adults with allergic rhinitis than for healthy people.

    Background The measure of fractional exhaled nitric oxide (FENO) in the airways is a useful tool to guide the diagnosis and titration of inhaled corticosteroids in patients with asthma. However, its role in diagnosis of allergic rhinitis (AR), especially in subjects with asthma, is not well established. Objective To study the cutoff of nasal FENO in the diagnosis of subjects with AR and AR-asthma compared to age-matched subjects without AR or asthma and its correlations with the clinical and functional characteristics. Methods The study was cross sectional and descriptive. Subjects were grouped into control subjects, AR, and AR-asthma, based on the inclusion criteria. Exhaled NO (nasal FENO, bronchial FENO, and alveolar concentration of NO) was measured by multiple flow electro-luminescence device. Results Six hundred twenty-eight subjects were included: 217 control subjects (children: n=98, 10±4 years; adults: n=119, 50±16 years), 168 subjects with AR (children: n=54, 10±3 years; adults: n=114, 49±15 years), and 243 subjects with AR-asthma (children: n=115, 10±3 years; adults: n=128, 51±14 years). Nasal peak inspiratory flow and peak expiratory flow were lower in subjects with AR and AR-asthma than in control subjects (P<0.01 and P<0.01; and P<0.05 and P<0.01, respectively). Nasal FENO levels were significantly higher in subjects with AR and AR-asthma than in control subjects (1614±629 and 1686±614 ppb vs 582±161 ppb; P<0.001 and P<0.001, respectively). In subjects with AR non-asthma, the cutoffs of nasal FENO for those diagnosed with AR were 775 ppb in children, 799 ppb in adults, and 799 in the general population (sensitivity: 92.68%, 92.63%, and 92.65%, respectively; specificity: 91.67%, 95.00%, and 96.87%, respectively). In subjects with AR-asthma, the cutoffs of nasal FENO were higher, especially in asthma children (1458 ppb; sensitivity: 72.97% and specificity: 95.83%). Conclusion Nasal FENO measurement is a useful technique for the diagnosis of AR

    Current treatment options for allergic rhinitis (AR) include allergen avoidance and environmental control, pharmacotherapy, nasal surgery and immunotherapy. Among these, immunotherapy is the only therapeutic option that modifies fundamental immunologic mechanism by inducing desensitization. Specific allergen immunotherapy has been used for 1 century since 1911 and subcutaneous immunotherapy (SCIT) has been demonstrated to be effective in asthma and AR. However, SCIT has several disadvantages such as inconvenience, invasiveness and potentially severe systemic reactions. Thus, sublingual immunotherapy (SLIT) has recently received much attention around the world as a treatment for AR and is now widely used to replace the subcutaneous route. SLIT has recently been introduced in Korea and is now available for AR treatment in the Asia-Pacific region. This review offers better understanding of SLIT for AR by summarizing published articles and our previous works regarding proposed mechanisms, indication and efficacy, safety and adverse events, and compliance.

    Allergic rhinitis (AR), the most common chronic disease in childhood is often ignored, misdiagnosed and/or mistreated. Undertreated AR impairs quality of life, exacerbates asthma and is a major factor in asthma development. It can involve the nose itself, as well as the organs connected with the nose manifesting a variety of symptoms. Evidence-based guidelines for AR therapy improve disease control. Recently, paediatric AR guidelines have been published by the European Academy of Allergy and Clinical Immunology and are available online, as are a patient care pathway for children with AR and asthma from the Royal College of Paediatrics and Child Health. Management involves diagnosis, followed by avoidance of relevant allergens, with additional pharmacotherapy needed for most sufferers. This ranges, according to severity, from saline sprays, through non-sedating antihistamines, oral or topical, with minimally bioavailable intranasal corticosteroids for moderate/severe disease, possibly plus additional antihistamine or antileukotriene. The concept of rhinitis control is emerging, but there is no universally accepted definition. Where pharmacotherapy fails, allergen-specific immunotherapy, which is uniquely able to alter long-term disease outcomes, should be considered. The subcutaneous form (subcutaneous immunotherapy) in children has been underused because of concerns regarding safety and acceptability of injections. Sublingual immunotherapy is both efficacious and safe for grass pollen allergy. Further studies on other allergens in children are needed. Patient, carer and practitioner education into AR and its treatment are a vital part of management.

    Although adult asthma is attributable to occupational factors and asthma and rhinitis are related, relatively few studies have investigated the prevalence of occupational rhinitis based on occupation, and knowledge of occupational rhinitis in Japan is currently limited. The objective of this cross-sectional study was to estimate the prevalence of allergic rhinitis among Japanese nursing professionals with asthma. A postal survey was conducted from October to December 2013 using translated versions of the European Community Respiratory Health Survey for the prevalence of asthma and State of the Impact of Allergic Rhinitis on Asthma Control questionnaire for the prevalence of rhinitis. Of 4,634 Japanese nursing professionals, 497 subjects had asthma, and 270 of these 497 subjects had allergic rhinitis (54.3%; 95% confidence interval [CI], 49.7-58.7). Latex allergy was significantly associated with allergic rhinitis (odds ratio, 1.77; 95% CI, 1.21-2.60). There was no relationship between employment period and prevalent allergic rhinitis. The results of this study provide fundamental information regarding occupational health among Japanese nursing professionals, including the prevalence of allergic rhinitis among Japanese nursing professionals with asthma and latex allergy as a potential risk factor for prevalent allergic rhinitis.

    The prevalence of allergic rhinitis is increasing globally due to various causes. It affects the quality life of a large group of people in all around the world. Allergic rhinitis still remains inadequately controlled with present medical means. The need of continuous medical therapy makes individuals anxious about the side effects of the drugs. So there is a need for an alternative strategy. Effects of spirulina, tinospora cordifolia and butterbur were investigated recently on allergic rhinitis in just very few investigations. Spirulina represents a blue-green alga that is produced and commercialized as a dietary supplement for modulating immune functions, as well as ameliorating a variety of diseases. This double blind, placebo controlled study, evaluated the effectiveness and tolerability of spirulina for treating patients with allergic rhinitis. Spirulina consumption significantly improved the symptoms and physical findings compared with placebo (P < 0.001***) including nasal discharge, sneezing, nasal congestion and itching. Spirulina is clinically effective on allergic rhinitis when compared with placebo. Further studies should be performed in order to clarify the mechanism of this effect.

    Allergic rhinitis a chronic inflammatory disease of the upper airways that has a major impact on the quality of life of patients and is a socio-economic burden. Understanding the underlying immune mechanisms is central to developing better and more targeted therapies. The inflammatory response in the nasal mucosa includes an immediate IgE-mediated mast cell response as well as a latephase response characterized by recruitment of eosinophils, basophils, and T cells expressing Th2 cytokines including interleukin (IL)-4, a switch factor for IgE synthesis, and IL-5, an eosinophil growth factor and on-going allergic inflammation. Recent advances have suggested new pathways like local synthesis of IgE, the IgE-IgE receptor mast cell cascade in on-going allergic inflammation and the epithelial expression of cytokines that regulate Th2 cytokine responses (i.e., thymic stromal lymphopoietin, IL-25, and IL-33). In this review, we briefly review the conventional pathways in the pathophysiology of allergic rhinitis and then elaborate on the recent advances in the pathophysiology of allergic rhinitis. An improved understanding of the immune mechanisms of allergic rhinitis can provide a better insight on novel therapeutic targets.

  18. Allergen immunotherapy and allergic rhinitis: false beliefs

    PubMed Central

    2013-01-01

    Background Over the last 100 years, several persistent misconceptions or ‘false beliefs’ have built up around allergen immunotherapy and its use in allergic rhinitis. This is perhaps because enthusiastic physicians administered complex allergen extracts to a diverse population of patients suffering from heterogeneous atopic conditions. Here, we review evidence that counters seven of these ‘false beliefs.’ Discussion 1. The symptoms of allergic rhinitis can be more heterogeneous, more severe and more troublesome in everyday life than many physicians believe. Large-scale epidemiological surveys show that the majority of allergic rhinitis patients have at least one symptom severe enough to interfere with sleep quality, productivity and/or well-being. 2. Allergen immunotherapy is not necessarily suitable for all allergic rhinitis patients (notably those with mild symptoms). Recent evidence from double-blind, placebo-controlled, randomized clinical trials suggests that the more severe the disease, the greater the treatment effect. 3. Allergen immunotherapy is often accused of lack of efficacy (relative to pharmacotherapy, for example). However, there are now many meta-analyses, systematic reviews and high-quality clinical trials that find overwhelmingly in favor of the efficacy of allergen immunotherapy (including sublingual formulations) in allergic rhinitis induced by pollen and, increasingly, other allergens. 4. Natural-exposure and challenge-chamber trials have shown that symptom relief may become apparent within months or even weeks of the initiation of allergen immunotherapy. 5. In pollen-induced allergic rhinitis, several years of subcutaneous or sublingual allergen immunotherapy are associated with sustained clinical efficacy after subsequent treatment cessation – confirming the disease-modifying nature of this therapy. 6. Most patients seeking treatment for allergic rhinitis are polysensitized, and allergen immunotherapy has proven efficacy in large

    Allergic inflammation in upper airways can act as a predisposing factor for infectious ear diseases. There are some evidences about the role of allergic rhinitis in chronic otitis media with effusion, but its role in establishing chronic suppurative otitis media (CSOM) has not been clearly shown. 68 adult patients with established CSOM, who were candidates for ear surgery, and 184 age- and sex-matched controls were evaluated for the presence of allergic rhinitis. Standard questionnaire was filled out for all participants. All patients and controls underwent skin prick test for 28 common regional aeroallergens, and serum total IgE was measured by means of ELISA method. Allergic rhinitis were defined as a positive responses to the questionnaire, positive skin prick test to at least one allergen, and/or high level of serum total IgE. Allergic rhinitis was diagnosed in 20 (29.41%) and 41 (22.28%) of patients and controls, respectively (P = 0.241) (OR = 1.28, CI = 0.69-2.36). Outdoor allergens, especially grass pollen, were the most prevalent allergens among both groups, but indoor allergens like mites and molds have a low prevalence. The study did not show a significant difference in the prevalence of AR in the CSOM patients compared to the controls. The intermittent nature of allergy and other less known intervening factors in the etiopathogenesis of CSOM make such a conclusion difficult.

    The history of allergic disease goes back to 1819, when Bostock described his own ‘periodical affection of the eyes and chest’, which he called ‘summer catarrh’. Since they thought it was produced by the effluvium of new hay, this condition was also called hay fever. Later, in 1873, Blackley established that pollen played an important role in the causation of hay fever. Nowadays, the definition of allergy is ‘An untoward physiologic event mediated by a variety of different immunologic reactions’. In this review, the term allergy will be restricted to the IgE-dependent reactions. The most important clinical manifestations of IgE-dependent reactions are allergic conjunctivitis, allergic rhinitis, allergic asthma and atopic dermatitis. However, this review will be restricted to allergic rhinitis. The histopathological features of allergic inflammation involve an increase in blood flow and vascular permeability, leading to plasma exudation and the formation of oedema. In addition, a cascade of events occurs which involves a variety of inflammatory cells. These inflammatory cells migrate under the influence of chemotactic agents to the site of injury and induce the process of repair. Several types of inflammatory cells have been implicated in the pathogenesis of allergic rhinitis. After specific or nonspecific stimuli, inflammatory mediators are generated from cells normally found in the nose, such as mast cells, antigen-presenting cells and epithelial cells (primary effector cells) and from cells recruited into the nose, such as basophils, eosinophils, lymphocytes, platelets and neutrophils (secondary effector cells). This review describes the identification of each of the inflammatory cells and their mediators which play a role in the perennial allergic processes in the nose of rhinitis patients. PMID:18475703

    Allergic rhinitis is an inflammatory disease that develops through immunoglobulin E in the rhino-ocular mucosa due to allergy. The main symptoms are runny nose, nasal congestion, sneezing and itchy nose. This study was designed to investigate the effect of allergic rhinitis on choroidal thickness. This study was planned as a case-control study. This study performed in a tertiary referral center. The study included 61 patients with allergic rhinitis and 35 healthy subjects. Patients in both groups underwent skin prick test. In allergic rhinitis patients and healthy persons; subfoveal, temporal and nasal choroidal thickness measurement was performed. The choroidal thicknesses were measured without pupil dilation using the Spectralis Optical Coherence Tomography. In the subfoveal and temporal region, choroidal tissue was followed up significantly thicker in allergic rhinitis patients statistically compared to healthy persons (p = 0.031, p = 0.049). However, no significant difference was followed up between the nasal choroidal thickness measurements statistically (p = 0.54). Runny nose (67.2%), sneeze (65.5%), stuffiness (62.2%), itching of the nose (40.9%), and nasal discharge (21.3%) complaints were observed significantly higher in the group having allergic rhinitis. The effect of allergic rhinitis on choroidal thickness were assessed and compared with the control group. Our study revealed that there was significant association between increased choroidal thickness and allergic rhinitis. Allergic sensitivity may play an important role in increased choroidal thickness.

    Local allergic rhinitis (LAR) is characterized by the presence of a nasal Th2 inflammatory response with local production of specific IgE antibodies and a positive response to a nasal allergen provocation test (NAPT) without evidence of systemic atopy. The prevalence has been shown to be up to 25% in subjects affected with rhinitis with persistence, comorbidity and evolution similar to allergic rhinitis. LAR is a consistent entity that does not evolve to allergic rhinitis with systemic atopy over time although patients have significant impairment in quality of life and increase in the severity of nasal symptoms over time. Lower airways can be also involved. The diagnosis of LAR is based mostly on demonstration of positive response to NAPT and/or local synthesis of specific IgE. Allergens involved include seasonal or perennial such as house dusts mites, pollens, animal epithelia, moulds (alternaria) and others. Basophils from peripheral blood may be activated by the involved allergens suggesting the spill over of locally synthesized specific IgE to the circulation. LAR patients will benefit from the same treatment as allergic patients using antihistamines, inhaled corticosteroids and IgE antagonists. Studies on immunotherapy are ongoing and will determine its efficacy in LAR in terms of symptoms improvement and evolution of the natural course of the disease.

    Bilastine is an orally administered, second-generation antihistamine used in the symptomatic treatment of seasonal or perennial allergic rhinoconjunctivitis and urticaria. In two well designed phase III trials, 14 days' treatment with bilastine was associated with a significantly lower area under the effect curve (AUEC) for the reflective total symptom score (TSS) than placebo in patients with symptomatic seasonal allergic rhinitis. Additionally, reflective nasal symptom scores were significantly lower in bilastine than placebo recipients in patients with a history of seasonal allergic rhinitis who were challenged with grass pollen allergen in a single-centre, phase II study. Neither bilastine nor cetirizine was effective in the treatment of perennial allergic rhinitis with regard to the mean AUEC for reflective TSS in another well designed phase III trial. However, results may have been altered by differences in some baseline characteristics and placebo responses between study countries. In another well designed phase III trial, compared with placebo, bilastine was associated with a significantly greater change from baseline to day 28 in the mean reflective daily urticaria symptom score in patients with chronic urticaria. There were no significant differences in primary endpoint results between bilastine and any of the active comparators used in these trials (i.e. cetirizine, levocetirizine and desloratadine). Bilastine was generally well tolerated, with a tolerability profile that was generally similar to that of the other second-generation antihistamines included in phase III clinical trials.

    Mites can sensitize and induce atopic disease in predisposed individuals and are an important deteriorating factor in patients with allergic rhinitis, asthma, and atopic dermatitis. Although Pyroglyphidae mites have been extensively studied, very scarce reports are available on Cheyletidae spp. especially regarding human respiratory pathology. The main objective of the present study is to investigate the clinical role of this predator mite (Cheyletus eruditus) as a respiratory antigen in a selected sensitized human population. Fifty-two adult patients were recruited from the outpatient allergy clinic to assess their eligibility for the study. The thirty-seven subjects with persistent allergic rhinitis (PAR) who fulfilled the ARIA criteria had a positive IgE response confirmed by skin prick test (SPT) to C. eruditus. Only those individuals (37/47) with a positive SPT to C. eruditus showed a positive nasal provocation test (NPT), while 10 patients with nonallergic mild-to-moderate persistent rhinitis, control group, had a negative NPT with C. eruditus. The present paper describes a new role for the predator mite Cheyletus eruditus as a respiratory allergen in a selected subset of patients in a subtropical environment afflicted with persistent nonoccupational allergic rhinitis.

    Rhinitis is caused by a variety of allergic and nonallergic mechanisms. Mild disease can usually be managed with avoidance measures alone. Allergen removal can also improve the severity of allergic rhinitis and can reduce the need for medications. Allergic rhinitis is represented by sneezing, nasal congestion, nasal pruritus, and rhinorrhea. Oral antihistamines should be used to treat patients with mild or occasional seasonal allergic rhinitis. Because of the variance in causes of nonallergic rhinitis, treatments also vary. Irrigation and debridement are the standard treatment of atrophic rhinitis. For gustatory rhinitis, pretreatment with ipratropium bromide can be used.

    Allergic rhinitis is the most common atopic disorder seen in the outpatient clinic setting diagnosed by history, physical exam and objective testing. According to the Allergic Rhinitis and its Impact on Asthma (ARIA) document, it is classified by chronicity (intermittent or persistent), and severity which is based on symptoms and quality of life (mild, or moderate/severe). It has enormous socioeconomic costs and significant reduction in quality of life. Allergen avoidance should be implemented, particularly in children, to reduce level of exposure; unfortunately efforts are often inadequate. Montelukast, a novel medication, is an antagonist to the leukotriene receptor. It is nonsedating, dosed once daily, and has a safety profile similar in adults and children with approval down to 6 months of age. A review of the literature undoubtedly establishes montelukast as a viable alternative for the treatment of seasonal allergic rhinitis. Its benefits are equivalent to antihistamines, when used as monotherapy, but less than intranasal corticosteroids. The addition of an antihistamine to montelukast does appear to have added benefits and at times is reported to be equivalent to intranasal corticosteroids. PMID:18360641

    Rhinitis and rhinosinusitis (with/without polyposis), either allergic or non-allergic, represent a major medical problem. Their associated comorbidities and relationship with family history have so far been poorly investigated. We assessed these aspects in a large population of patients suffering from rhinosinusal diseases. Clinical history, nasal cytology, allergy testing and direct nasal examination were performed in all patients referred for rhinitis/rhinosinusitis. Fibre optic nasal endoscopy, CT scan and nasal challenge were used for diagnosis, when indicated. A total of 455 patients (60.7% male, age range 4-84 years) were studied; 108 (23.7%) had allergic rhinitis, 128 (28.1%) rhinosinusitis with polyposis, 107 (23.5%) non-allergic rhinitis (negative skin test); 112 patients had associated allergic and non-allergic rhinitis, the majority with eosinophilia. There was a significant association between non-allergic rhinitis and family history of nasal polyposis (OR = 4.45; 95%CI = 1.70-11.61; p = 0.0019), whereas this association was no longer present when allergic rhinitis was also included. Asthma was equally frequent in non-allergic and allergic rhinitis, but more frequent in patients with polyposis. Aspirin sensitivity was more frequent in nasal polyposis, independent of the allergic (p = 0.03) or non-allergic (p = 0.01) nature of rhinitis. Nasal polyposis is significantly associated with asthma and positive family history of asthma, partially independent of the allergic aetiology of rhinitis.

    Disturbances of the upper and lower airways frequently coexist, and the association between allergic rhinitis and asthma is an example of that. The relationship between allergic rhinitis and asthma probably occurs because both, nasal and bronchial mucosas are elements of a "united airway", and on the other hand, allergic rhinitis and asthma are manifestations of a common allergic disease. Allergic rhinitis and asthma are not only statistically associated, but have pathophysiological and clinical similarities. Allergic rhinitis is itself a risk factor for the development of asthma, but additionally may confound the diagnosis of asthma and may exacerbate coexisting asthma. The management of allergic rhinitis, mainly with the use of intranasal corticosteroids, improve asthma symptoms and lung function in asthmatic patients. Several mechanisms have been proposed to link the nose and bronchi, which include: postnasal drip of inflammatory cells and pro-inflammatory molecules; a possible nasobronchial neural reflex; an increased exposure of the lower airways to dry and cold air as well as aeroallergens because the mouth breathing secondary to nasal obstruction; and an increased susceptibility to rhinovirus infection secondary to an increased ICAM-1 expression in the nasal mucosa of patients with allergic rhinitis. A better understanding of the rhinitis-asthma relationship nature might allow the creation of better strategies for the integral treatment of patients with these diseases.

    Allergic rhinitis is a high-cost, high-prevalence disease. In the year 2000, over $6 billion was spent on prescription medications to treat this illness. Although it is not associated with severe morbidity and mortality, allergic rhinitis has a major effect on the quality of life of the more than 50 million Americans with this illness. Intranasal corticosteroids (INCS) and nonsedating antihistamines (NSAH) are the most common prescription medications for this disease. INCS are recognized as the most effective treatment regimen for chronic symptoms. NSAH are perceived as important in the treatment of patients with mild disease, or as add-on therapy to INCS. When the literature is reviewed, the INCS produce the greatest decrease in total nasal symptom scores, the largest effect size, when compared with NSAH. Both classes of medications produce similar effects on concurrent allergic conjunctivitis. Further recent studies indicate that the INCS are also superior when used on an as-needed basis, and that there is little clinical benefit from the addition of loratadine to intranasal fluticasone. INCS have lower average wholesale prices as a class than the NSAH. Since the INCS are the dominant medication in efficacy studies and cost less, cost-effectiveness studies always favor intranasal corticosteroids.

    Voice problems are seldom reported in pollen allergy, although the allergic reaction involves the entire airways. The objective of this study was to investigate voice dysfunction during the pollen season in patients with allergic rhinitis. Thirty patients with verified birch pollen allergy and 30 controls were investigated twice, during the pollen season and outside the pollen season. Both times they scored respiratory and voice symptoms, the latter with the validated questionnaire Voice Handicap Index (VHI), and performed standardized voice recordings. These recordings were analyzed in a controlled manner by a professional voice therapist. During the allergy season, patients reported more respiratory and voice symptoms compared with controls. Those with blinded scored voice dysfunction scored their voice quality during springtime as 31 mm (95% confidence interval [CI] 20-42 mm), compared with 13 mm (95% CI 6-21 mm for participants without voice dysfunction (P<0.01). Furthermore, the group with experienced voice dysfunction scored significantly higher on the VHI in the functional and physical domains and in the total VHI score. Although voice problems during the pollen season are rarely discussed, in allergic rhinitis the larynx may also be involved. These findings support that some patients experience voice change, an experience which can be objectively confirmed.

    Ornamental plants (OPs) can lead to immediate-type sensitization and even asthma and rhinitis symptoms in some cases. This study aimed to evaluate sensitization to OPs in patients with asthma and/or allergic rhinitis and to determine the factors affecting the rate of sensitization to OPs. A total of 150 patients with asthma and/or allergic rhinitis and 20 healthy controls were enrolled in the study. Demographics and disease characteristics were recorded. Skin-prick tests were performed with a standardized inhalant allergen panel. Skin tests by "prick-to-prick" method with the leaves of 15 Ops, which are known to lead to allergenic sensitization, were performed. Skin tests with OPs were positive in 80 patients (47.1%). There was no significant difference between OP sensitized and nonsensitized patients in terms of gender, age, number of exposed OPs, and duration of exposure. Skin test positivity rate for OPs was significantly high in atopic subjects, patients with allergic rhinitis, food sensitivity, and indoor OP exposure, but not in patients with pollen and latex allergy. Most sensitizing OPs were Yucca elephantipes (52.5%), Dieffenbachia picta (50.8%), and Euphorbia pulcherrima (47.5%). There was significant correlation between having Saintpaulia ionantha, Croton, Pelargonium, Y. elephantipes, and positive skin test to these plants. Sensitivity to OPs was significantly higher in atopic subjects and patients with allergic rhinitis, food allergy, and indoor OP exposure. Furthermore, atopy and food sensitivity were found as risk factors for developing sensitization to indoor plants. Additional trials on the relationship between sensitization to OPs and allergic symptoms are needed.

    We investigated the antioxidant effects of curcumin in an experimental rat model of allergic rhinitis (AR). Female Wistar albino rats (n = 34) were divided randomly into four groups: healthy rats (control group, n = 8), AR with no treatment (AR + NoTr group, n = 10), AR with azelastine HCl treatment (AR + Aze group, n = 8), and AR with curcumin treatment (AR + Curc group, n = 8). On day 28, total blood IgE levels were measured. For measurement of antioxidant activity, the glutathione (GSH) level and catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) activities were measured in both inferior turbinate tissue and serum. Malondialdehyde (MDA) levels were measured only in inferior turbinate tissue, and paraoxonase (PON) and arylesterase (ARE) activities were measured only in serum. Statistically significant differences were found for all antioxidant measurements (GSH levels and CAT, SOD, GSH-Px activities in the serum and tissue, MDA levels in the tissue, and PON and ARE activities in the serum) between the four groups. In the curcumin group, serum SOD, ARE, and PON and tissue GSH values were higher than the control group. Moreover, tissue GSH levels and serum GSH-Px activities in the curcumin group were higher than in the AR + NoTr group. In the azelastine group, except MDA, antioxidant measurement values were lower than in the other groups. Curcumin may help to increase antioxidant enzymes and decrease oxidative stress in allergic rhinitis. We recommend curcumin to decrease oxidative stress in allergic rhinitis.

    For patients suffering from allergic rhinitis (AR), general practitioners (GPs) are often their first source of medical advice. It is one of the top-ten reasons for a visit to the primary care clinics and AR was estimated to be 10-40% of the total patient visits in about 50% of the primary care clinics. The standard of management for AR among GPs is thus a key outcome assessment of AR management and implementation of international guidelines in general healthcare practice. PMID:23130327

    We conducted a population-based study involving a stratified cluster disproportionate random sample of 2868 adults aged 20 to 74 years selected from five housing estates (Yishun, Toa Payoh, Jurong East, Geylang/Eunos and Bukit Merah). Chronic rhinitis was defined as the usual presence of symptoms of blocked or running nose, apart from colds or the flu, lasting for more than a year. Allergic rhinitis was considered to be present if these symptoms were associated with conjunctivitis or recognisable provocation by commonly known allergens, namely house dust, dogs, cats, birds, pollen, or medicines. The estimated general population prevalence of chronic rhinitis was 10.8% (95% confidence interval (CI) 8.8-12.7). Higher prevalences were noted in males, in younger adults, in Indians and Chinese, in those with higher socio-economic status, and in Toa Payoh, Jurong East and Geylang/Eunos. The prevalence of allergic rhinitis was 5.5% (95% CI 4.5-6.5). The most common 'allergenic' factor in allergic rhinitis was house dust (73%); provocation by birds, cats or dogs (5%), grass or tree pollens (5%), and medicine (5%) was less common but likely to have been under-recognised. Provocation by change in temperature (54%) and early in the morning (64%) was equally frequent in both 'allergic' and 'non-allergic' rhinitis; cigarette smoke, petrol and diesel fumes, food and work environment were less common (4-12%). Allergic rhinitis was highly significantly associated with asthma (13.9% in allergic rhinitis, 4.4% in non-allergic rhinitis, and 2.2% in non-rhinitic subjects).

    Hyeonggaeyeongyo-tang (HYT) is an ancient formula of oriental medicine traditionally used to treat rhinitis; however, clinical evidence has not yet been established. The aim of this study was to investigate the short-term and long-term efficacy and safety of HYT for chronic rhinitis. Adult subjects with chronic rhinitis symptoms were recruited. The subjects received HYT for 4 weeks and had follow-up period of 8 weeks. Any medicines used to treat nasal symptoms were not permitted during the study. The skin prick test was performed to distinguish the subjects with allergic rhinitis from those with nonallergic rhinitis. After treatment, the total nasal symptoms score and the Rhinoconjunctivitis Quality of Life Questionnaire score significantly improved in the whole subject group, in the allergic rhinitis group, and in the nonallergic rhinitis group, with no adverse events. This improvement lasted during a follow-up period of 8 weeks. Total IgE and eosinophil levels showed no significant difference after treatment in the allergic rhinitis group. HYT improved nasal symptoms and quality of life in patients with allergic rhinitis and nonallergic rhinitis. This is the first clinical study to evaluate the use of HYT to treat patients with rhinitis. This trial has been registered with the ClinicalTrials.gov Identifier NCT02477293. PMID:27698676

    Although allergic rhinitis is considered a raising medical problem in many countries it is often undertreated. The reasons for this phenomenon are not completely clear.The aim of this study is to evaluate factors associated with allergic rhinitis under-/no treatment.A sample of 518 allergic rhinitis patients recruited by their primary care physicians, as a part of the ARGA study, were invited to fill in a specific questionnaire regarding rhinitis symptoms, treatment, and rhinitis-related work/social disability. Chi-square test and logistic regression were performed to assess risk factors for allergic rhinitis under-/no treatment.Over one out of four patients had no treatment despite the symptoms and 13.5% were inadequately treated. Participants with asthma (OR 0.47, 95% CI 0.30-0.75) and conjunctivitis (0.44, 95% CI 0.27-0.71) were at lower risk of allergic rhinitis under-/no treatment: in asthmatics this reduction was related mainly to the concomitant asthma treatment (OR 0.19, 95% CI 0.10-0.37).Asthmatics with under-/not treated rhinitis had the highest prevalence of rhinitis-related quality of life impairment.Under-/no treatment for allergic rhinitis is still rather frequent despite the relevance of this disease. The simultaneous presence of asthma and an anti-asthmatic therapy are able to influence positively the treatment. Targeted interventions toward a better characterization and a tight follow-up of rhinitis patient without asthma are needed.

    Allergic rhinitis is a common nasal disorder with a high impact on quality of life, high social costs in therapies, and a natural development towards asthma. Pharmacological therapy is based on several genres of medications, of which intranasal corticosteroids are currently the most widespread. Thermal water treatment has traditionally been used as adjunctive treatment for chronic rhinitis and sinusitis. The present study was carried out to assess the clinical efficacy of nasal inhalation of radioactive oligomineral water vapours from the Merano hot spring and to compare it with the clinical efficacy of mometasone furoate nasal spray. A comparative prospective study was performed in 90 allergic patients treated at Merano hot springs: a group of 54 subjects treated with radioactive thermal oligomineral water and a control group of 36 subjects treated with mometasone nasal spray. Patients of both groups were assessed before and after treatment by Sino-Nasal Outcome Test questionnaire, active anterior rhinomanometry with flow and resistance monitoring, measurement of mucociliary transport time, and cytological examination of nasal brushing/scraping. The study showed that inhalation treatment with radioactive hydrofluoric thermal water for two weeks produces an objective clinical and cytological improvement in allergic patients, similar to that obtained with mometasone furoate nasal spray.

    Onset of action is recognized as an important pharmacologic property of allergic rhinitis (AR) medications. This study was designed to evaluate the onset of action of loratadine/montelukast (L/M; 10 mg/10 mg) versus placebo in subjects with ragweed-induced seasonal AR (SAR). A single-center, double-blind, parallel-group study of ragweed-sensitive AR subjects (n = 310) was performed in the Environmental Exposure Unit (EEU). Subjects were exposed to ragweed pollen in the EEU and symptoms were recorded at 30, 60, 90, and 120 minutes before a single dose of L/M or placebo. After dosing, symptoms were recorded for 4 hours, at 15-minute intervals for the first 2 hours and at 30-minute intervals for the final 2 hours. The primary end point was time to onset of action of L/M, defined as the first time point at which the mean change from baseline in total symptom score (TSS) for L/M became and remained significantly better than placebo. Secondary end points included nasal congestion scores and peak nasal inspiratory flow (PNIF). The onset of action of L/M for TSS was 1 hour and 15 minutes (p = 0.005 versus placebo). L/M reduced nasal congestion as indicated by significant improvements in both the nasal congestion score (p = 0.011) and the PNIF measurements (p = 0.007) within 1 hour and 15 minutes postdose. The incidence of treatment-emergent adverse events was similar between groups. The onset of action after treatment with L/M was 1 hour and 15 minutes for TSS, as well as nasal congestion. L/M was well tolerated.

    Allergic rhinitis affects 10% to 20% of Americans. It frequently coexists with other conditions, such as allergic conjunctivitis, sinusitis, and asthma, and is associated with impaired occupational function and performance in school, decreased quality of life, and increased health care costs. An efficacious agent with minimal adverse effects and a lack of drug interactions is needed to help simplify treatment of allergic rhinitis, especially in patients with comorbidities. Controlled studies of intranasal cromolyn sodium therapy for patients with seasonal and perennial allergic rhinitis are reviewed, and appropriate candidates for treatment with this agent are discussed. Cromolyn inhibits the degranulation of sensitized mast cells, thereby blocking the release of inflammatory and allergic mediators. It reduces symptoms of allergic rhinitis, and, when used prophylactically, cromolyn can prevent symptoms from occurring. Controlled studies comparing cromolyn with placebo, intranasal corticosteroids, and antihistamines have shown the efficacy of cromolyn in relieving rhinitis symptoms. In addition, because cromolyn is poorly absorbed systemically, it is well tolerated and not associated with drug interactions. Intranasal cromolyn has an excellent safety record, is available as an over-the-counter medication, and has been proved to be efficacious in patients with allergic rhinitis.

    Patient nonadherence significantly burdens the treatment of allergic rhinitis (AR). Fewer than half of prescribed doses of intranasal corticosteroid medication are taken. The challenges for immunotherapies are even greater. While sustained treatment for 3 to 5 years is required for full benefit, most patients receiving immunotherapy, either subcutaneous or sublingual, stop treatment within the first year. Although research into interventions to improve AR adherence is lacking, lessons learned from adherence interventions in other chronic health conditions can be applied to AR. Two well-established, overriding models of care-the chronic care model and patient-centered care-can improve adherence. The patient-centered care model includes important lessons for allergy providers in their daily practice, including understanding and targeting modifiable barriers to adherence. Additionally, recent studies have begun to leverage health information and communication technologies to reach out to patients and promote adherence, extending patient-centered interventions initiated by providers during office visits.

    Foreign body neglected in the nasal cavity for many years leads to the formation of a rhinolith, which gradually increases in size. Nasal obstruction and persistent foul smelling nasal discharge usually are the main presenting symptoms, although some might be silent. This paper presents and discuss a case of 19-year-old female patient whose main complaint was nasal obstruction for many years and treated as allergic rhinitis. Diagnosis was confirmed with computed tomography scan, and it was removed endoscopically without complications. We think that proper examination, which includes endoscopic evaluation, should be done to reach the diagnosis. A computed tomography scan confirmed the diagnosis and helped in planning the best treatment option. PMID:27053994

    2013-01-01

    The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative has had a significant impact, by raising awareness of allergic rhinitis (AR) and improving the diagnosis and treatment of AR sufferers. ARIA classifies the severity of AR as "mild" or "moderate/severe" on the basis of "yes"/"no" answers to four questions. This two-point classification has been criticized as providing little guidance on patient management; patients with "mild" AR are unlikely to consult a physician, whereas the group of patients with "moderate/severe" seen by specialists is heterogeneous. These perceived shortcomings have prompted attempts to improve the ARIA classification or, by analogy with the Global Initiative for Asthma (GINA), adopt approaches based on "disease control" in AR. Even though "disease severity", "disease control" and "responsiveness to treatment" are different (albeit related) metrics, they are not mutually exclusive. Currently, there is no single, accepted definition, but we propose that "disease control" in AR can combine (i) measurements of the severity and/or frequency of daily or nocturnal symptoms, (ii) impairments in social, physical, professional and educational activities, (iii) respiratory function monitoring and (iv) exacerbations (e.g. unscheduled medical consultations and rescue medication use). Although control-based classifications have a number of limitations (e.g. their dependence on treatment compliance and the patient's psychological status), these instruments could be used as an adjunct to the ARIA severity classification and regional practice parameters. Here, we assess the strengths and weaknesses of the current two-level ARIA classification, analyze published proposals for its modification and review the literature on instruments that measure AR control. We conclude that there is a need for research in which severity is compared with control in terms of their effects on patient management. PMID:23419058

    Allergic rhinitis is one of the most common chronic diseases. There are a number of effective therapeutic options for allergic rhinitis patients, such as intranasal corticosteroids. How to avoid the adverse effects of these traditional medicines has come to public attention and started the search for effective and safe medicine. We used BALB/c mice with experimental allergic rhinitis, and determined that levamisole delivered locally (intranasal, i.n.) could attenuate early-phase inflammatory response, decrease histamine, suppress edema and eosinophil infiltration, and diminish the ovalbumin-specific serum IgE level. Detailed analysis of cytokine gene expression showed that levamisole can decrease IL-4, IL-5 and IL-13 mRNA and increase IL-12, IL-18 and IFN-gamma mRNA. Levamisole showed analogous effects of down-regulating Th2 cytokines with budesonide and distinct up-regulating effects on Th1 cytokines gene expression. Our findings offer potential options for allergic rhinitis therapy.

    Background Allergic rhinitis (AR) has high prevalence and substantial socio-economic burden. Material/Methods The study included 35 Italian Centers recruiting an overall number of 3383 adult patients with rhinitis (48% males, 52% females, mean age 29.1, range 18–45 years). For each patient, the attending physician had to fill in a standardized questionnaire, covering, in particular, some issues such as the ARIA classification of allergic rhinitis (AR), the results of skin prick test (SPT), the kind of treatment, the response to treatment, and the satisfaction with treatment. Results Out of the 3383 patients with rhinitis, 2788 (82.4%) had AR: 311 (11.5%) had a mild intermittent, 229 (8.8%) a mild persistent, 636 (23.5%) a moderate-severe intermittent, and 1518 (56.1%) a moderate-severe persistent form. The most frequently used drugs were oral antihistamines (77.1%) and topical corticosteroids (60.8%). The response to treatment was judged as excellent in 12.2%, good in 41.3%, fair in 31.2%, poor in 14.5%, and very bad in 0.8% of subjects. The rate of treatment dissatisfaction was significantly higher in patients with moderate-to-severe AR than in patients with mild AR (p<0.0001). Indication to allergen immunotherapy (AIT) was significantly more frequent (p<0.01) in patients with severe AR than with mild AR. Conclusions These findings confirm the appropriateness of ARIA guidelines in classifying the AR patients and the association of severe symptoms with unsuccessful drug treatment. The optimal targeting of patients to be treated with AIT needs to be reassessed. PMID:25366169

    House dust mite allergens express protease activity and it has been suggested that this property has pathogenic effects by increasing airway absorption. In accordance, house dust mite allergens may increase mucosal permeability in vitro. The objective of the present study was to examine nasal absorption of desmopressin (1-deamino-8-D-arginine vasopressin) in patients with perennial house dust mite allergic rhinitis and in healthy subjects in vivo. Patients with perennial allergic rhinitis were examined after a 4-week treatment withdrawal period, when symptoms of allergic rhinitis occurred, and healthy subjects were examined together with the patients. Desmopressin (20 microg ml(-1)) was moved into the nasal cavity using a nasal pool-device that contained 15 ml fluid. The fluid was kept in the nasal cavity for 15 min and then recovered. Urine was collected for 24 h after the nasal administration and the urinary excretion of desmopressin was determined as an index of nasal absorption. The urinary excretion of desmopressin was 1148+/-535 pmol 24 h(-1) in patients with perennial house dust mite allergic rhinitis and 1012+/-291 pmol 24 h(-1) in healthy subjects. We conclude that nasal airway absorption of the 1067 Da peptide desmopressin is unaffected in perennial house dust mite allergic rhinitis compared with healthy subjects.

    Leukotrienes comprise a family of products of the 5-lipoxigenase pathway of arachidonic acid metabolism. The cysteinil leukotrienes C4, D4 and E4 account for the biologic activity that was previously termed "slow-reacting substance of anaphylaxis". The proinflammatory effects of cysteinil leukotrienes (cys LTs) have been well described in asthma and rhinitis. The cys LTs induce broncospasm (1,000 times more potent than histamine), edema, mucus, hypersecretion, attract inflammatory cells like eosinophils, increase airway hyperreactivity, vascular leakage, and stimulate takikinins. The leukotriene synthesis can be inhibited in two different places; through inhibition of 5 lipooxigenase activating protein (FLAP) in the 5 lipooxigenase pathway, with the drug Zyleuton, or blocking the cysLT1 receptor with the drugs Montelukast, Pranlukast, Zafirlukast. The cysLTs play an important role in pathophysiology of allergic rhinitis and comorbid diseases like rhinosinusitis and nasal polyposis. Antileukotrienes are prescribed in the treatment of allergic rhinitis. Allergic rhinitis is a complex IgE inflammatory disease of the upper airways. It is the most common allergic disease ocurring in 10 to 20% of adults and up to 30% of children. It may be seasonal or perennial, intermittent or persistent. Sneezing, itching, watery rhinorrea and nasal obstruction are classic symptoms. Ocular itching, lacrimation and redness also occur frequently as almost 50% of the patients also have allergic conjunctivitis. Allergic rhinitis may be mild, moderate or severe disease. It may impair cognition, school and work performance. It affects productivity, behavior and mood changes, causes sleep disturbance and diminish the patient's quality of life. Allergic rhinitis is a common comorbid condition with asthma, sinusitis, otitis media, nasal polyposis and recurrent respiratory infections.

    Allergic rhinitis (AR) is rarely found in isolation and needs to be considered in the context of systemic allergic disease associated with numerous comorbid disorders, including asthma, chronic middle ear effusions, sinusitis, and lymphoid hypertrophy with obstructive sleep apnea, disordered sleep, and consequent behavioral and educational effects. The coexistence of allergic rhinitis and asthma is complex. First, the diagnosis of asthma may be confused by symptoms of cough caused by rhinitis and postnasal drip. This may lead to either inaccurate diagnosis of asthma or inappropriate assessment of asthma severity with over treatment of the patient. The term "cough variant rhinitis" is therefore proposed to describe rhinitis that manifest itself primarily as cough that results from postnasal drip. Allergic rhinitis, however, has also a causal role in asthma; it appears both to be responsible for exacerbating asthma and to have a role in its pathogenesis. Postnasal drip with nasopharyngeal inflammation leads to a number of other conditions. Thus sinusitis is a frequent extension of rhinitis and is one of the most frequently missed diagnoses. Allergen exposure in the nasopharynx with release of histamine and other mediators can cause Eustachian tube obstruction possibly leading to middle ear effusions. Chronic allergic inflammation of the upper airway causes lymphoid hypertrophy with prominence of adenoidal and tonsillar tissue. This may be associated with poor appetite, poor growth, obstructive sleep apnea, mouth breathing, pharyngeal irritation and dental abnormalities. Allergic rhinitis is therefore part of a spectrum of allergic disorders that can profoundly affect the well being and quality of life of a child. Prospective cohort studies are required to assess the disease burden caused by allergic rhinitis in childhood, its consequences due to delay in diagnosis and treatment, and to further assess the potential educational impairment that may result.

    Summary Background Allergic rhinitis is a disease with a high global disease burden, but risk factors that contribute to this condition are not well understood. Objective To assess the prevalence and risk factors of allergic rhinitis in two Peruvian populations with disparate degrees of urbanization. Methods We conducted a population-based, cross-sectional study on 1441 children aged 13–15 years at enrollment (mean age 14.9 years, 51% boys) to investigate the prevalence of allergic disease. We used a standardized, Spanish validated questionnaire to determine the prevalence of allergic rhinitis and asked about sociodemographics and family history of allergies. Children also underwent spirometry, exhaled nitric oxide, allergy skin testing to 10 common household allergens and provided a blood sample for measurement of 25OH vitamin D and total serum IgE. Results Overall prevalence of allergic rhinitis was 18% (95% CI 16% to 20%). When stratified by site, the prevalence of allergic rhinitis was 23% Lima vs. 13% in Tumbes (P < 0.001); however, this difference was no longer significant after controlling for subject- specific factors (P = 0.95). There was a strong association with other allergic diseases: 53% of children with asthma had allergic rhinitis vs. 15% in those without asthma (P < 0.001) and 42% of children with eczema vs. 17% of those without eczema (P < 0.001). Important risk factors for allergic rhinitis were parental rhinitis (adjusted OR = 3.0, 95% CI 1.9–4.7 for 1 parent and adjusted OR = 4.4, 95% CI 1.5–13.7 for 2 parents); allergic sensitization to common household aeroallergens (1.6, 1.1–2.3); being overweight (1.5, 1.0–2.3); exhaled nitric oxide ≥20 ppb (1.9, 1.3–2.7); and total serum IgE ≥ 95th percentile (2.4, 1.2–4.8). Population attributable risk of important factors for allergic rhinitis were 25% for high exhaled nitric oxide, 22% for allergic sensitization to common household aeroallergens, 22% for paternal rhinitis, 10% for

    Chronic rhinitis is a very common disease, as the prevalence in the general population resulted to be 40%. Allergic rhinitis has been considered to be the most frequent form of chronic rhinitis, as non-allergic rhinitis has been estimated to account for 25%. However, several evidences suggested that non-allergic rhinitis have been underrated, especially in children. In pediatrics, the diagnostic definition of non-allergic rhinitis has been often limited to the exclusion of an allergic sensitization. Actually, local allergic rhinitis has been often misdiagnosed as well as mixed rhinitis has not been recognized in most cases. Nasal cytology is a diagnostic procedure being suitable for routine clinical practice with children and could be a very useful tool to characterize and diagnose non-allergic rhinitis, providing important clues for epidemiological analysis and clinical management.

However, several evidences suggested that non-allergic rhinitis have been underrated, especially in children. In pediatrics, the diagnostic definition of non-allergic rhinitis has been often limited to the exclusion of an allergic sensitization. Actually, local allergic rhinitis has been often misdiagnosed as well as mixed rhinitis has not been recognized in most cases. Nasal cytology is a diagnostic procedure being suitable for routine clinical practice with children and could be a very useful tool to characterize and diagnose non-allergic rhinitis, providing important clues for epidemiological analysis and clinical management.

    Treatment with beclomethasone dipropionate aerosol (BDA), 50 mug four times daily in each nostril, was compared with placebo therapy in a double-blind non-crossover trial of 30 matched patients with allergic rhinitis induced by ragweed pollen. The trial was started at the beginning of the ragweed season and continued for 42 days. Response to treatment was assessed from information on daily diary cards, weekly objective measurements of nasal patency and measurement of total eosinophil count (TEC) before treatment and at week 4. Patients in the BDA group had significantly less (P less than 0.05) sneezing, rhinorrhea and nasal stuffiness at 36 days, cough at 10 days and antihistamine consumption at 17 days. There was no significant difference between the groups in eye symptoms, nasal airway inspiratory resistance, maximum inspiratory nasal flow or TEC. Overall comparison with previous pollen seasons by the patients indicated moderate to great improvement in 86% of the BDA group and in 13% of the placebo group (P less than 0.01). Minor side effects were noted by two patients in each group. PMID:782679

  15. Sublingual or subcutaneous immunotherapy for allergic rhinitis?

    Allergen immunotherapy is effective in patients with allergic rhinitis (AR) and, unlike antiallergic drugs, has been shown to modify the underlying cause of the disease, with proved long-term benefits. Subcutaneous immunotherapy (SCIT) has been the gold standard, whereas sublingual immunotherapy (SLIT) has emerged as an effective and safe alternative. Previous Cochrane systematic reviews and meta-analyses have confirmed that both SLIT and SCIT are effective in patients with seasonal AR, whereas evidence for their efficacy in patients with perennial disease has been less convincing. Recent large, adequately powered trials have demonstrated reductions in both symptoms and use of rescue medication in patients with seasonal and those with perennial AR. Here we appraise evidence for SCIT versus SLIT based on indirect evidence from Cochrane reviews and recent well-powered double-blind, randomized controlled trials versus placebo and the limited direct evidence available from randomized blind head-to-head comparisons. At present, based on an overall balance of efficacy and side effects, the patient is in equipoise. Pending definitive comparative trials, choice might be determined largely by the local availability of SCIT and SLIT products of proved value and personal (patient) preference.

    Background: In our experience Allergic Rhinitis (AR) patients suffer from voice problems more than health subjects. Aims: To investigate the acoustic analysis of voice, stroscopic findings of larynx and Voice Handicap Index scores in allergic rhinitis patients compared with healthy controls. Study Design: Case-control study. Methods: Thirty adult patients diagnosed with perennial allergic rhinitis were compared with 30 age- and sex-matched healthy controls without allergy. All assessments were performed in the speech physiology laboratory and the testing sequence was as follows: 1. Voice Handicap Index (VHI) questionnaire, 2. Laryngovideostroboscopy, 3. Acoustic analyses. Results: No difference was observed between the allergic rhinitis and control groups regarding mean Maximum Phonation Time (MPT) values, Fo values, and stroboscopic assessment (p>0.05). On the other hand, mean VHI score (p=0.001) and s/z ratio (p=0.011) were significantly higher in the allergic rhinitis group than in controls. Conclusion: Our findings suggest that the presence of allergies could have effects on laryngeal dysfunction and voice-related quality of life. PMID:25667789

    Introduction Allergic diseases are becoming more prevalent in elderly patients. Allergic diseases have been observed in patients with Alzheimer’s disease (AD). The prevalence of atopic bronchial asthma, allergic rhinitis and atopic dermatitis was analyzed in such elderly Polish population. Aim Analysis of the presence of allergic diseases in the patients with AD in Poland, including asthma, allergic rhinoconjunctivitis and atopic dermatitis. Material and methods The recruitment of subjects with AD was conducted at 6 sites representative of Polish rural and urban areas, and 1060 subjects with a mean age of 69.2 ±5.1 years were screened. Medical examinations, an original questionnaire, skin prick testing for common aeroallergens and appropriate serum-specific IgE assays were performed. Results Probable atopy was diagnosed in 234 (22.1%) analyzed patients, including 127 women (21.5% of women) and 234 men (22.8% of men). The average prevalence associated with age and sex in this population for bronchial asthma was 2.9%, atopic dermatitis/eczema was 0.6%, seasonal allergic rhinitis was 6.6%, perennial allergic rhinitis was 11.1% and polymorphous atopic disease was 4.4%. The most frequent positive results were recorded for the following allergens: mixed grass, Dermatophagoides pteronyssinus, Dermatophagoides farinae and Alternaria. Conclusions One-fifth of diagnosed patients with AD have allergic disease requiring treatment. PMID:27881942

    Allergic rhinitis is a widespread allergic disease, with 35-40% prevalence in the world population. It is characterized with increasing frequency, particularly in children's population. Goal of the work - study of psycho-emotional profile in adolescents with allergic rhinitis of different severity. Single-stage research was conducted, in compliance with the ethical norms. Study included 86 children (41% girls and 45% boys) of age from 11 to 13 years with allergic rhinitis of different severity and 30 healthy children. For the purpose of study of the patients' psychological profile Esenek Personality Questionnaire (EPQ) intended for assessment of characterological and individual psychological features in children and adolescents (10-15 years) was used. Psycho-emotional sphere of the adolescents with allergic rhinitis was assessed also by Psychopathologic Symptom Checklist (Symptom Checklist-90-Revised-SCL-90-R). Clinical scale of self-assessment of psychical condition is widely applied in ambulatory and hospital practice. At the final stage of research the mathematical-statistical data processing was provided by means of SPSS/v12 software package. According to the research results, susceptibility to significant and mild introversion was identified in severe and average AR cases. Such patients are often locked into their inner world. These children are reserved, communicate with the parents and close friends only. They make decisions with due care, love order, control their emotions, are pessimistic and rarely aggressive. Results of neuroticism study by G. Esenek techniques are provided in Table. Neuroticism is associated with the lability of nervous system, characterizes emotional condition or emotional lability (emotional stability or instability). According to the research results, allergic rhinitis is characterized with emotional instability, anxiety, as manifested by unsatisfactory adaptation, instable nature, depression, low resistance to the stress situations

    Introduction Even though the links between upper and lower airway had been of interest to clinicians since long back, it has not attracted the attention of the researchers till recent past. But the evidence is still far from conclusive, due to limited number of randomized controlled trials available on subjects with concomitant allergic rhinitis and asthma. This gap in the knowledge is even more conspicuous in Indian population. Aim The current study is conducted with an objective of comparing the efficacy and tolerability of intranasal Fluticasone and oral Montelukast in treatment of allergic rhinitis and bronchial asthma. Materials and Methods The study was a prospective randomized, single blinded, comparative, parallel group study, with two intervention groups conducted in a tertiary teaching hospital in Chennai, Southern India. One hundred and twenty patients diagnosed with concomitant diagnosis of allergic rhinitis and bronchial asthma was randomly allocated to either Fluticasone propionate aqueous nasal spray or oral Montelukast group. Results Out of total 120 subjects recruited, 108 subjects were included in the final analysis. The mean reduction in asthma and rhinitis symptom scores and improvement in PEFR was higher for Group A, compared to Group B during all the follow-up periods. No statistically significant difference was observed in proportion of subjects reporting exacerbations in the current study. Both the treatments were well tolerated. Conclusion Addition of intranasal Fluticasone propionate to Salmeterol plus Fluticasone is beneficial in improving asthma control, allergic rhinitis control and lung functions as compared to oral Montelukast. Thereby the use of intranasal Fluticasone Propionate in comparison to oral Montelukast in control of Allergic Rhinitis is justified as per the significant improvement in outcome measures.

    Purpose Nonallergenic irritants can aggravate the symptoms of rhinitis. We investigated the clinical responses of children with allergic rhinitis (AR) and nonallergic rhinitis (NAR) to nonallergenic irritants, and identified factors associated with these responses. Methods Children with chronic rhinitis (n=208) were classified as having AR or NAR based on the presence of aeroallergen-specific IgE. Healthy controls (n=24) were recruited for comparison. The Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines were used to classify patients, and their irritant score (0-21 points) and current symptom score (5-35 points) were measured. Subjects with irritant scores ≥3 and <3 were classified as having irritant and nonirritant rhinitis, respectively. Results The mean age of enrolled subjects was 6.8 years (range: 1.8-16.0 years). The AR and NAR groups had similar irritant scores (P=0.394) and proportions of subjects with irritant scores ≥3 (P=0.105). Irritant score correlated positively with symptom score (P=0.005), and the proportion of subjects with irritant scores ≥3 was greater in children with moderate-severe rhinitis than in those with mild rhinitis (P=0.046). Multiple logistic regression analysis indicated that the presence of atopic eczema increased the risk for sensitivity to a nonallergenic irritant (aOR=2.928, 95% CI 1.567-5.473, P=0.001). Conclusions Response to a nonallergenic irritant was useful for gauging the severity of rhinitis, but not for differentiating AR from NAR. AR and NAR patients with atopic eczema may increase nasal sensitivity to nonallergenic irritants. PMID:27126728

    Reporting two of our cases we wanted to point to a great dilemma related to the final diagnosis. Recently, such cases have been more frewuently seen, since in all patients with allergic rhinitis conditions of the lower airways is examined before the administration of the specific immunotherapy. Therefore, we may see patients who are still free of pulmonary sings, despite of positive specific and/or non specific bronchoprovocative tests. The presented cases with evidenced allergic rhinitis are probably in the phase of development of allergic bronchial asthma, the phase of "allergic inflammation" of the lower airways, not clinically manifested yet.

    Allergic inflammation is associated with mood disorders, exacerbation of depression, and suicidal behavior. Mediators of inflammation modulate sleep , with Th1 cytokines promoting NREM sleep and increasing sleepiness and Th2 cytokines (produced during allergic inflammation) impairing sleep. As sleep impairment is a rapidly modifiable suicide risk factor strongly associated with mood disorders, we review the literature leading to the hypothesis that allergic rhinitis leads to mood and anxiety disorders and an increased risk of suicide via sleep impairment. Specifically, allergic rhinitis can impair sleep through mechanical (obstructive) and molecular (cytokine production) processes. The high prevalence of mood and anxiety disorders and allergy, the nonabating suicide incidence, the currently available treatment modalities to treat sleep impairment and the need for novel therapeutic targets for mood and anxiety disorders, justify multilevel efforts to explore disturbance of sleep as a pathophysiological link.

    The objective of this study was to investigate the effect of intranasal phototherapy on nasal microbial flora in patients with allergic rhinitis. This prospective, self-comparised, single blind study was performed on patients with a history of at least two years of moderate-to-severe perennial allergic rhinitis that was not controlled by anti-allergic drugs. Thirty-one perennial allergic rhinitis patients were enrolled in this study. Before starting the test population on their intranasal phototherapy, the same trained person took a nasal culture from each subject by applying a sterile cotton swab along each side of the nostril and middle meatus. Each intranasal cavity was irradiated three times a week for two weeks with increasing doses of irradiated. At the end of the intranasal phototherapy, nasal cultures were again obtained from the each nostril. The study found that after intranasal phototherapy, the scores for total nasal symptoms decreased significantly but bacterial proliferation was not significantly different before and after phototherapy. We have shown that intranasal phototherapy does not change the aerobic nasal microbial flora in patients with perennial allergic rhinitis.

    Allergic rhinitis (AR) is a chronic inflammatory disease of rhino-ocular mucosa, affecting up to 40% of population worldwide. Chinese herbal medicines and Acupuncture, adopted thousands of years in China, has good effect on allergic rhinitis. This study evaluates the effects of Moxibustion with Chinese herbal in treating patients with allergic rhinitis over a 1-year follow-up. A randomized controlled trial was conducted in a sample of 355 participants recruited from Guangdong general hospital of China. After baseline measurements, participants were randomly assigned to treatment-group or control group. Treatment group received Moxibustion with Chinese herbal. Control group received Loratadine. The main outcomes, including symptom severity and quality of life were measured using the Allergic Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). Both moxibustion with Chinese herbal and Loratadine improve nose symptoms such as stuffy/blocked, sneezing, runny nose, itchy nose, sore nose and post-nasal drip in patients with AR. Symptoms fatigue, loss of taste, afraid of cold/wind and cold limb were improved significantly in moxibustion with Chinese herbal group. The mean quality of life scores decreased in both groups after treatment. Compare to control group, moxibustion with Chinese herbal is more effective than Loratadine in improving the quality of life in patients with AR. The results show moxibustion with Chinese herbal was effective to reduce symptoms and enhance quality of life in patients with allergic rhinitis. It is a simple, convenient and economic therapy for patients with AR. Further controlled trials of its effects in patients with allergic rhinitis are recommended. PMID:26629174

    Background Sleep disordered breathing (SDB) and sleep disturbances have been reported to be associated with allergic rhinitis and asthma. However, population-based studies of this issue in the elderly are rare. Objective To investigate the impact of self-reported rhinitis and asthma on sleep apnea and sleep quality using polysomnography in an elderly Korean population. Methods A total of 348 elderly subjects who underwent one-night polysomnography study among a randomly selected sample were enrolled. Study subjects underwent anthropometric and clinical evaluations. Simultaneously, the prevalence and co-morbid status of asthma and allergic rhinitis, and subjective sleep quality were evaluated using a self-reported questionnaire. Results Ever-diagnosis of allergic rhinitis was significantly more prevalent in subjects with SDB compared with those without SDB. Subjects with an ever-diagnosis of allergic rhinitis showed a higher O2 desaturation index and mean apnea duration. Indices regarding sleep efficiency were affected in subjects with a recent treatment of allergic rhinitis or asthma. Waking after sleep onset was longer and sleep efficiency was lower in subjects who had received allergic rhinitis treatment within the past 12 months. Subjects who had received asthma treatment within the past 12 months showed significantly lower sleep efficiency than others. Conclusion Our study indicates that a history of allergic rhinitis is associated with increased risk of SDB in the elderly. Sleep disturbance and impaired sleep efficiency were found in the subjects who had received recent treatment of allergic rhinitis or asthma. Physicians should be aware of the high risk of sleep disorders in older patients with respiratory allergic diseases. PMID:28245272

    Itching and sneezing represent two of the main bothersome symptoms, apart from nasal obstruction and rhinorrhea in allergic rhinitis. Apparently, activation of the central and peripheral nervous system plays a major role in the pathophysiology of this process. Sensory nerves of the afferent trigeminal system including myelinated Adelta-fibres and thin, non-myelinated C-fibres of the nasal mucosa transmit signals generating sensations, including itching and motor reflexes, such as sneezing. These nerves can be stimulated by products of allergic reactions and by external physical and chemical irritants. Via axon reflex inflammatory neuropeptides including the tachykinins substance P (SP) and neurokinin A (NKA) and the calcitonin gene related peptide are released, leading to vasodilatation, increased vascular permeability (concept of "neurogenic inflammation"), glandular activation, leukocyte recruitment and differentiation of immune cells including mast cells, eosinophils, lymphocytes and macrophages. The present paper describes nasal (micro-) anatomy and innervation and explains the central and peripheral mechanisms initiating itching and sneezing in allergic rhinitis. Further, the role of neuropeptides and neurotrophins with regard to neuronal and immune cell activation which might play a key role in the future treatment of allergic rhinitis are discussed.

    In order to compare patterns of indoor air perception, including perceptions of temperature, air movement, indoor air quality (IAQ), mental concentration, and comfort, 33 subjects either with persistent allergic rhinitis or controls were exposed to different temperatures and constant relative humidity in an experimental office environment. Results were obtained by means of a self-administered visual analogue scale, analyzed using mean score comparisons and principal component analysis. At 14 degrees C, the rhinitis group reported higher scores for sensations of air dryness than controls. At 18 degrees C, in the rhinitis group, there was a correlation between dry, stagnant air, and difficult mental concentration. This group also correlated heat, dry air, and poor IAQ, in contrast to the control group, which correlated comfort, easy mental concentration, and freshness. At 22 degrees C, the rhinitis group correlated heat, dryness, stagnant air, and overall discomfort. This group also correlated non-dry air, freshness, and comfort, whereas the control group correlated heat, humidity, good indoor air, freshness, and comfort. This study suggests that the rhinitis group perceives indoor temperatures of 14 degrees C as dryer than controls do, and that at 18 and 22 degrees C this group positively correlates different adverse perceptions of IAQ. By means of a self-administered questionnaire in an experimental condition, the present study compares subjective patterns of indoor air perception from individuals with respiratory allergy (allergic rhinitis) to control individuals. It reports different patterns of perception of indoor air quality (IAQ) between the two groups, suggesting that allergic individuals could have different IAQ perception.

    Sublingual immunotherapy (SLIT) was introduced in the 1980s as a safer option to subcutaneous immunotherapy and in the latest decade achieved significant advances. Its efficacy in allergic rhinitis is supported by a number of meta-analyses. The development of SLIT preparations in tablets to fulfill the requirements of regulatory agencies for quality of allergen extracts made available optimal products for grass-pollen-induced allergic rhinitis. Preparations of other allergens based on the same production methods are currently in progress. A notable outcome of SLIT, that is shared with subcutaneous immunotherapy, is the evident cost-effectiveness, showing significant cost savings as early as 3 months from starting the treatment, that become as high as 80% compared with drug treatment in the ensuing years.

    Introduction The relevance of allergic rhinitis is unquestionable. This condition affects people's quality of life and its incidence has increased over the last years. Objective Thus, this study aims to analyze the effectiveness of subcutaneous injectable immunotherapy in cases of nasal itching, sneeze, rhinorrhea and nasal congestion in allergic rhinitis patients. Methods In the present study, the same researcher analyzed the records of 281 patients. Furthermore, the researchers identified allergens through puncture cutaneous tests using standardized extracts containing acari, fungi, pet hair, flower pollen, and feathers. Then, the patients underwent treatment with subcutaneous specific immunotherapy, using four vaccine vials for desensitization, associated with environmental hygiene. The authors analyzed conditions of nasal itching, sneeze, rhinorrhea, and nasal congestion throughout the treatment, and assigned them with a score ranging from zero (0), meaning absence of these symptoms to three (3), for severe cases. The symptoms were statistically compared in the beginning, during, and after treatment. Results In this study, authors analyzed the cases distribution according to age and the evolution of symptomatology according to the scores, comparing all phases of treatment. The average score for the entire population studied was 2.08 before treatment and 0.44 at the end. These results represent an overall improvement of ∼79% in symptomatology of allergic rhinitis in the studied population. Conclusion The subcutaneous immunotherapy as treatment of allergic rhinitis led to a reduction in all symptoms studied, improving the quality of life of patients, proving itself as an important therapeutic tool for these pathological conditions.

    The association between ADHD and allergy remains controversial. Our previous findings suggest that nerve growth factor may link the nervous and immune systems. The primary objective of this study was to determine if a combination of cetirizine + methylphenidate is effective in children with comorbid ADHD and allergic rhinitis. We also examined the role of nerve growth factor in these comorbidities. Our randomized, double-blind, placebo-controlled, crossover study enrolled 38 children diagnosed with comorbid ADHD and allergy using cetirizine (n = 12), sustained-release methylphenidate (n = 12), or cetirizine + methylphenidate (n = 14). Endpoints compared baseline to posttreatment evaluations for allergic rhinitis and ADHD scores. Serum nerve growth factor levels were measured using ELISA. For allergy endpoints, combination therapy produced results superior to individual therapy. For ADHD, similar scores were achieved for individual therapy; however, combination therapy resulted in improved scores. Nerve growth factor levels were downregulated following this trend. We conclude that ADHD and allergic rhinitis may have common mechanism and represent a comorbid condition that links the nervous system to the immune system. Further studies are needed. PMID:27872863

    Allergic rhinitis (AR) is a chronic disorder with a high prevalence in the general population. The symptoms of AR can impair the cognitive capabilities of the affected people. The study of communication skills and AR interaction has not been adequately discussed. We aimed to analyze Social Communication Skills of university students with AR. Fifty patients suffering from AR and 50 healthy subjects were studied. All participants completed two questionnaires [Social Communication Skills Rating Scale (SCSRS) and Communication Questionnaire] for the assessment of social communication skills. Total scores of both SCSRS and Communication Questionnaire were higher in participants with AR than controls. When the questions of SCSRS were compared between the groups one by one, significant difference was observed between the groups for questions numbered 1-9 and 11, 12 (p < 0.05). Also, significant differences were observed between the groups for questions numbered 4, 5, 6, 7 and 8 of Communication Questionnaire (p < 0.05). Results of our study indicate that AR could negatively affect the social communication skills of the patients with AR. More research is however needed to validate this hypothesis.

    Allergic rhinitis is a chronic respiratory disease. Sympathetic hypofunction is identified in all of the allergic rhinitis patients. Moreover, allergic rhinitis is associated with decreased peak nasal inspiratory flow (PNIF) and impaired lung functions. The aim of this study was to investigate effects of six-week of aquatic exercise on the autonomic nervous system function, PNIF and lung functions in allergic rhinitis patients. Twenty-six allergic rhinitis patients, 12 males and 14 females were recruited in this study. Subjects were diagnosed by a physician based on history, physical examination, and positive reaction to a skin prick test. Subjects were randomly assigned to two groups. The control allergic rhinitis group received education and maintained normal life. The aquatic group performed aquatic exercise for 30 minutes a day, three days a week for six weeks. Heart rate variability, PNIF and lung functions were measured at the beginning, after three weeks and six weeks. There were statistically significant increased low frequency normal units (LF n.u.), PNIF and showed decreased high frequency normal units (HF n.u.) at six weeks after aquatic exercise compared with the control group. Six weeks of aquatic exercise could increase sympathetic activity and PNIF in allergic rhinitis patients.

    Background The CC-chemokine receptor-3 (CCR3) has emerged as a target molecule for pharmacological intervention in allergic inflammation. Objective To examine whether a dual CCR3 and H1-receptor antagonist (AZD3778) affects allergic inflammation and symptoms in allergic rhinitis. Methods Patients with seasonal allergic rhinitis were subjected to three seven days' allergen challenge series. Treatment with AZD3778 was given in a placebo and antihistamine-controlled design. Symptoms and nasal peak inspiratory flow (PIF) were monitored in the morning, ten minutes post challenge, and in the evening. Nasal lavages were carried out at the end of each challenge series and α2-macroglobulin, ECP, and tryptase were monitored as indices of allergic inflammation. Results Plasma levels of AZD3778 were stable throughout the treatment series. AZD3778 and the antihistamine (loratadine) reduced rhinitis symptoms recorded ten minutes post challenge during this period. AZD3778, but not the anti-histamine, also improved nasal PIF ten minutes post challenge. Furthermore, scores for morning and evening nasal symptoms from the last five days of the allergen challenge series showed statistically significant reductions for AZD3778, but not for loratadine. ECP was reduced by AZD3778, but not by loratadine. Conclusions AZD3778 exerts anti-eosinophil and symptom-reducing effects in allergic rhinitis and part of this effect can likely be attributed to CCR3-antagonism. The present data are of interest with regard to the potential use of AZD3778 in allergic rhinitis and to the relative importance of eosinophil actions to the symptomatology of allergic rhinitis.

    Background: Antioxidants have a preventive or therapeutic role in oxygen free radical–mediated cell and tissue damage. The study aimed to investigate the therapeutic effects of antioxidants and intranasal steroid fluticasone furoate (FF) on the clinical outcome of patients with perennial allergic rhinitis. Methods: Subjects with perennial allergic rhinitis (n = 61) were randomly divided into two groups, group A (n = 30) received FF and group B (n = 31) received FF with antioxidants for 6 weeks. Nasal and ocular symptoms were evaluated weekly by using a four-point categoric scale. The efficacy of the study drug was assessed based on the mean change from baseline of the total daytime nasal symptom scores, total nighttime nasal symptom scores, and the composite symptom scores. Results: The combined therapy (FF with antioxidants) resulted in marked improvements (p ≤ 0.05) in the mean total daytime nasal symptom scores, total nighttime nasal symptom scores, and composite symptom scores of subjects compared with ones treated with intranasal steroid (FF) alone, which highlighted the therapeutic effect of antioxidants in allergic rhinitis. Conclusion: Significant improvement in clinical outcome was observed in subjects who received antioxidants along with FF. However, because this was an open-label study, the results must be interpreted with caution, and further double-blind, placebo-controlled, dose-ranging trials supplemented with different antioxidants together with intranasal steroids are suggested.

    Concealing emotions at work can cause considerable psychological stress. While there is extensive research on the adverse health effects of concealing emotions and the association between allergic diseases and stress, research has not yet investigated whether concealing emotions at work is associated with allergic rhinitis. Allergic rhinitis is a common disease in many industrialized countries, and its prevalence is increasing. Thus, our aim was to determine the strength of this association using data from three years (2007-2009) of the 4th Korean National Health and Nutrition Examination Survey. Participants (aged 20-64) were 8,345 individuals who were economically active and who had completed the questionnaire items on concealing emotions at work. Odds ratio (OR) and 95% confidence intervals (95% CIs) were calculated for allergic rhinitis using logistic regression models. Among all participants, 3,140 subjects (37.6%) reported concealing their emotions at work: 1,661 men and 1,479 women. The OR (95% CIs) for allergic rhinitis among those who concealed emotions at work versus those who did not was 1.318 (1.148-1.512). Stratified by sex, the OR (95% CIs) was 1.307 (1.078-1.585) among men and 1.346 (1.105-1.639) among women. Thus, individuals who concealed their emotions at work were significantly more likely to have a diagnosis of AR in comparison to those who did not. Because concealing emotions at work has adverse health effects, labor policies that aim to reduce this practice are needed.

    The authors examined 25 children with allergic rhinitis, who were sensitive to grass, weed and tree pollens. During the allergic season nasal lavage was performed then repeated after 4 weeks of loratadine treatment. Tryptase, IL-5, ECP, TNF-alpha and RANTES levels were measured from the nasal lavage fluid. Tryptase, IL-5, and ECP levels were decreased significantly while the decrease of RANTES and TNF-alpha levels was not significant. The authors emphasize that loratadine is an effective anti-inflammatory drug which affects the early and late phase of immediate hypersensitivity. In the moderate cases loratadine is enough to relieve the symptoms, while in the severe forms anti-allergic eye drops and nasal antihistamine or steroid spray has to be added.

    Several unmet needs have been identified in allergic rhinitis: identification of the time of onset of the pollen season, optimal control of rhinitis and comorbidities, patient stratification, multidisciplinary team for integrated care pathways, innovation in clinical trials and, above all, patient empowerment. MASK-rhinitis (MACVIA-ARIA Sentinel NetworK for allergic rhinitis) is a simple system centred around the patient which was devised to fill many of these gaps using Information and Communications Technology (ICT) tools and a clinical decision support system (CDSS) based on the most widely used guideline in allergic rhinitis and its asthma comorbidity (ARIA 2015 revision). It is one of the implementation systems of Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA). Three tools are used for the electronic monitoring of allergic diseases: a cell phone-based daily visual analogue scale (VAS) assessment of disease control, CARAT (Control of Allergic Rhinitis and Asthma Test) and e-Allergy screening (premedical system of early diagnosis of allergy and asthma based on online tools). These tools are combined with a clinical decision support system (CDSS) and are available in many languages. An e-CRF and an e-learning tool complete MASK. MASK is flexible and other tools can be added. It appears to be an advanced, global and integrated ICT answer for many unmet needs in allergic diseases which will improve policies and standards.

    Allergic rhinitis (AR) affects approximately 500 million people worldwide, and prevalence is increasing. Second-generation nonsedating antihistamines are first-line treatments for seasonal AR (SAR). This study was performed to evaluate early SAR symptom relief with second-generation antihistamines through a retrospective analysis of previously published data. In this study, 835 subjects aged 12-60 years with a > or = 2-year history of SAR were randomized to receive loratadine, 10 mg, once daily; fexofenadine, 60 mg, twice daily; or placebo for 7 days. Each subject recorded the severity of five symptoms of SAR on a scale of 0-3. This primary post hoc efficacy analysis was the mean change from baseline in daily average A.M./P.M. reflective and instantaneous total symptom score (TSS) on days 2 and 3. Significantly greater mean reductions from baseline were shown with loratadine compared with fexofenadine in average A.M./P.M. reflective TSS on days 2 (-3.51 versus -2.84, respectively; p < 0.002) and 3 (-3.80 versus -3.19, respectively; p = 0.007) and in average A.M./P.M. instantaneous TSS on day 3 (-3.68 versus -3.15, respectively; p = 0.022). Similar results were noted in average A.M./P.M. reflective and instantaneous total nasal symptom scores and for 10 of 20 individual symptom time points (p < 0.05). Loratadine was significantly more effective than placebo for all time points (p < 0.001). Early, sustained symptom relief was seen with loratadine, suggesting that it may be more effective for treating SAR symptoms.

    2013-07-01

    The prevalence of seasonal allergic rhinitis in the western world is high and increasing. Besides considerably affecting physical and psychosocial aspects of patients' lives, allergic rhinitis is often associated with allergic asthma and may aggravate this condition over time. Specific immunotherapy is currently the only approved therapy that can modify the underlying disease process and induce long-term tolerance to allergens. Pollinex Quattro is a subcutaneous four injections immunotherapy consisting of tyrosine-absorbed specific allergoids and enhanced with the adjuvant monophosphoryl lipid A (MPL(®)). MPL(®) induces a significant Th 1-type immune response, characterized by an increase of allergen-specific IgG antibody levels and dampening of the IgE response during allergen exposure. Due to this dual action of stimulating the immune system, Pollinex Quattro is clinically effective after only four injections given pre-seasonally. A large clinical program has demonstrated efficacy and tolerability of Pollinex Quattro in children, adolescents and adults with grass and tree pollen allergy. A health economics study concluded that an immunotherapy with only 4 injections might be more cost-beneficial than other application forms of immunotherapy.

    Aim To assess the quality of life of Polish patients with asthma and/or allergic rhinitis before the implementation and after 30–36 months of immunotherapy. Material and methods Two hundred patients have been involved in the study: 101 with allergic asthma and 99 with pollinosis. In order to collect research material, the Polish versions of AQLQ (Asthma Quality of Life) and RQLQ (Rhinoconjunctivitis Quality of Life) questionnaires have been used. The self-administered questionnaires concerned such data as age, sex and the patients’ subjective evaluation of their quality of life. Results The average increase in quality of life of patients with asthma was 0.84 and of patients with allergic rhinitis – 1.50. A hypothesis was made that changes of quality of life in each examined group differed significantly. A test for two fractions showed that for patients with asthma it was 7.74 and for patients with allergic rhinitis – 10.38. A statistical analysis showed no such relation in the group of patients with asthma (coefficient of correlation = 0.08) and a slight correlation in the group of patients with allergic rhinitis (coefficient of correlation = 0.20). Applied tests did not show any significant differences, which means that an average increase in quality of life does not depend on sex and age of both examined groups. Conclusions On the basis of the research conducted among patients before and after a 3-year period of immunotherapy, the following conclusions have been drawn: 1) immunotherapy significantly improves the objective quality of life in both groups; 2) a slight correlation has been identified between the objective and subjective dimension of quality of life amongst patients with asthma, what contributes to a better quality of life; 3) in both study groups, no significant relationship between gender or age and improvement in quality of life has been noted; 4) immunotherapy, from the point of view of the improvement of quality of life, is a valuable

    The current population-based study investigated the onset of neonatal urinary tract infection (UTI) and the associated risks of allergic rhinitis. From 2000 to 2005, 3285 children with neonatal UTI and 13,128 randomly selected controls were enrolled from the National Health Insurance Research Database in Taiwan and frequency matched by gender, urbanization of residential area, parental occupation, and baseline year. We compared the risk of allergic rhinitis between the non-UTI and UTI cohorts by performing multivariable Cox regression analysis. We observed a significant relationship between UTI and allergic rhinitis. This study examined 16,413 patients, among whom 3285 had UTI and 13,128 did not have UTI. The overall incidence rate ratio of allergic rhinitis was 1.41-fold higher in the UTI cohort than in the non-UTI cohort (100.2 vs 70.93 per 1000 person-y). After potential risk factors were adjusted for, the adjusted hazard ratio of allergic rhinitis was 1.32 (95% confidence interval = 1.23-1.41). Regardless of gender, the UTI cohort had a higher risk of allergic rhinitis than that of the non-UTI cohort. The patients with UTI in different follow-up durations were equally susceptible to developing allergic rhinitis compared with those without UTI, especially in follow-up durations shorter than 5 years. Patients with UTI and particular comorbidities such as infections and neonatal jaundice had a significantly increased risk of allergic rhinitis. UTI in newborns is significantly associated with the development of allergic rhinitis in childhood and might be a risk factor for subsequent childhood allergic rhinitis.

    Objective This study was conducted to investigate whether the add-on treatment of allergic rhinitis (AR) based on the Self-assessment of Allergic Rhinitis and Asthma (SACRA) questionnaire for assessing AR control improves both AR and asthma control in asthmatic patients with AR. Methods This multi-center prospective study was performed in Nagano prefecture, Japan. Two hundred five asthmatic patients and 23 respiratory physicians participated in the study. We administered add-on AR treatments based on the results of the SACRA questionnaire. After the first SACRA questionnaire, 67 asthmatic patients agreed to receive an add-on AR treatment. Three months after the AR treatment, a secondary SACRA questionnaire, asthma control test (ACT), and pulmonary function tests were performed. Results After the add-on AR treatment, the visual analogue scales (VASs) for AR and asthma, as assessed by the SACRA questionnaire and ACT score, were significantly improved in the patients of the AR+ group. With regard to the pulmonary function tests, the percent predicted vital capacity, and percent predicted forced expiratory volume in one second were also significantly improved. Regardless of whether the patients had previously undergone leukotriene receptor antagonists (LTRA) treatment, the VASs for AR and asthma and the ACT score were significantly improved in the AR+ group. However, the vital capacity (VC), forced vital capacity (FVC) and forced expiratory volume (FEV1) were only significantly improved in the AR+ group that had previously undergone LTRA treatment. Conclusion SACRA questionnaire-based add-on AR treatment would be convenient for the detection of AR by respiratory physicians and would offer improved asthma control. This questionnaire can also be used to assess the therapeutic effects. PMID:28049997

    Introduction The effect of nitric oxide (NO) on the human body is very important due its physiological regulation of the following functions of airways: modulation of ciliary movement and maintenance of sterility in sinuses. Aim To evaluate the diagnostic significance of NO concentrations in exhaled air from the upper and lower airways in patients diagnosed with allergic rhinitis (AR). Material and methods The subjects included in the study were a group of 30 people diagnosed with sensitivity to environmental allergens and a control group consisting of 30 healthy subjects. The measurement of NO in the air exhaled from the lower and upper airways was performed using an on-line method by means of Restricted Exhaled Breath (REB), as well as using the measurement procedure (chemiluminescence) set out in the guidelines prepared in 2005 by the American Thoracic Society and the European Respiratory Society. Results In the late phase of the allergic reaction, higher values of the level of exhaled NO concentration from the lower airways were observed in the groups of subjects up to the threshold values of 25.17 ppb in the group of subjects with year-round allergic rhinitis and 21.78 ppb in the group with diagnosed seasonal allergic rhinitis. The difference in the concentration of NO exhaled from the lungs between the test group and the control group in the 4th h of the test was statistically significant (p = 0.045). Conclusions Exhaled NO should be considered as a marker of airway inflammation. It plays an important role in the differential diagnosis of allergy. PMID:27279816

    Background The protective effect of farm upbringing on allergic rhinitis is well known, but how upbringing in other environments influences the development of allergic rhinitis is scarcely investigated. The aim of this study was to investigate the association between place of upbringing and pet keeping in childhood and allergic rhinitis and nasal symptoms in adulthood. Methods The population-based Respiratory Health in Northern Europe study includes subjects from Denmark, Norway, Sweden, Iceland, and Estonia born in 1945–1973. This paper analyses 13,376 participants of the third study wave. Six categories of place of upbringing were defined: farm with livestock, farm without livestock, village in rural area, small town, city suburb, and inner city. Pets in the home at birth and during childhood were recorded. Data were analysed using adjusted logistic regression models. Results Livestock farm upbringing predicted less adult allergic rhinitis [odds ratio (OR) 0.68, 0.54–0.85] and nasal symptoms (OR 0.82, 0.68–0.99) than city upbringing, and an urban–rural gradient with decreasing risk per level of urbanisation was observed (OR 0.92, 0.88–0.94). Pets in the home at birth (OR 0.78, 0.68–0.88) and during childhood (OR 0.83, 0.74–0.93) were associated with less subsequent allergic rhinitis. Pet keeping did not explain the protective effect of place of upbringing. Conclusion Risk of allergic rhinitis and nasal symptoms in adulthood was inversely associated with the level of urbanisation during upbringing. Pets at birth decreased the risk further, but did not explain the urban–rural gradient. Persistent beneficial effects of microbial diversity in early life might be an explanation for the findings.

    Curcumin has commonly been used for the treatment of various allergic diseases. However, its precise anti-allergic rhinitis effect and mechanism remain unknown. In the present study, the effect of curcumin on allergic responses in ovalbumin (OVA)-induced allergic rhinitis mouse was investigated. We explored the effect of curcumin on the release of allergic inflammatory mediators, such as histamine, OVA-specific IgE, and inflammatory cytokines. Also, we found that curcumin improved rhinitis symptoms, inhibited the histopathological changes of nasal mucosa, and decreased the serum levels of histamine, OVA-specific IgE and TNF-α in OVA-induced allergic rhinitis mice. In addition, curcumin suppressed the production of inflammatory cytokines, such as TNF-α, IL-1β, IL-6 and IL-8. Moreover, curcumin significantly inhibited PMA-induced p-ERK, p-p38, p-JNK, p-Iκ-Bα and NF-κB. These findings suggest that curcumin has an anti-allergic effect through modulating mast cell-mediated allergic responses in allergic rhinitis, at least partly by inhibiting MAPK/NF-κB pathway.

    Background Allergic rhinitis is an inflammatory disease of the upper airway mucosa that also affects leukocytes in bone marrow and peripheral blood. Toll-like receptor 9 (TLR9) is a receptor for unmethylated CpG dinucleotides found in bacterial and viral DNA. The present study was designed to examine the expression of TLR9 in the nasal mucosa and in leukocytes derived from different cellular compartments during symptomatic allergic rhinitis. Methods The study was based on 32 patients with seasonal allergic rhinitis and 18 healthy subjects, serving as controls. Nasal biopsies were obtained before and after allergen challenge. Bone marrow, peripheral blood and nasal lavage fluid were sampled outside and during pollen season. The expression of TLR9 in tissues and cells was analyzed using immunohistochemistry and flow cytometry, respectively. Results TLR9 was found in several cell types in the nasal mucosa and in different leukocyte subpopulations derived from bone marrow, peripheral blood and nasal lavage fluid. The leukocyte expression was generally higher in bone marrow than in peripheral blood, and not affected by symptomatic allergic rhinitis. Conclusion The widespread expression of TLR9 in the nasal mucosa along with its rich representation in leukocytes in different compartments, demonstrate the possibility for cells involved in allergic airway inflammation to directly interact with bacterial and viral DNA.

    The effects of stressful events, such as surgery, on patients with allergic diseases are unclear. The aim of this study was to evaluate whether patients with allergic rhinitis (AR) are more susceptible to stress and oxidative stress than non-allergic individuals. 20 AR patients and 20 non-allergic rhinitis (NAR) patients were recruited to this study and underwent nasal septoplasty. To evaluate the degrees of stress and oxidative stress, we collected urine and blood samples 1 day before and 1 day after surgery. Stress was assessed by measuring urine cortisol levels. Oxidative stress was assessed by calculating the balance of reactive oxygen metabolites (ROM) measured by the diacron reactive oxygen metabolites test, and antioxidant capacity (AC) was measured by the biological antioxidant potential test. In both groups, the level of post-operative urine cortisol was significantly higher than the pre-operative level, with no significant difference between the two groups. ROM levels were significantly higher in both groups after surgery than before surgery. The antioxidant capacity of the AR group was lower after surgery than before surgery, while it was greater in the NAR group after surgery. There were no significant differences in pre- or post-operative ROM or AC levels between the two groups. The ROM/AC ratio was significantly higher after surgery in the AR group than it was in the NAR group. The post-operative ROM/AC imbalance of AR patients suggests that these patients might be vulnerable to stress, especially oxidative stress.

    Objective Previous studies have reported comorbidity of attention deficit and hyperactivity disorder (ADHD) and allergic diseases. The current study investigated ADHD like behavioral symptoms and parenting stress in pediatric allergic rhinitis. Methods Eighty-seven children (6-13 years old) with allergic rhinitis and 73 age- and sex-matched children of control group were recruited. Diagnosis and severity assessments of allergic rhinitis were determined by a pediatric allergist. The Parenting Stress Index-Short Form (PSI-SF), ADHD Rating Scale (ARS), and Child Behavior Checklist (CBCL) were completed by their mothers. Results In the allergic rhinitis group, the total PSI-SF score (p<0.01), ARS score (p<0.01), the subscale scores of the CBCL including somatization, attentional problems and emotional instability (p=0.01; p<0.01; p<0.01) and prevalence of ADHD (p=0.03) were significantly higher than those of the control group. Among mothers of children with allergic rhinitis, those of children with comorbid ADHD demonstrated significantly higher parenting stress than those without comorbid ADHD (p<0.01). Parenting stress was correlated with severity of child's allergic symptoms and the ARS total score (beta=0.50, p<0.01; beta=0.39, p<0.01). There was a significant correlation between allergic symptom severity and the ARS total score (B=8.4, SD=2.5, t=3.3, p<0.01). Conclusion This study demonstrated that ADHD symptoms were common in children with allergic rhinitis, and this factor increased parenting stress and disrupted the parent-child relationship. Routine evaluation and early management of ADHD symptoms in pediatric allergic rhinitis may benefit families of children with allergic rhinitis. PMID:25110499

    Despite the well-documented therapeutic effects of histone deacetylase inhibitor (HDACi) on various diseases, including arthritis and asthma, the therapeutic effect of HDACi on allergic rhinitis remains unmentioned in the literature. This study investigated the therapeutic effect of sodium butyrate (SoB), a form of HDACi, on mice with allergic rhinitis. The results showed that the expression levels of histone deacetylase 1 (HDAC1), histone deacetylase 3 (HDAC3), and thymic stromal lymphopoietin (TSLP) were significantly upregulated in mice with allergic rhinitis, whereas H3 acetylation at lysine 9 (H3AcK9) was decreased. The intranasal application of SoB inhibited the expression levels of TSLP levels and upregulated the expression of H3AcK9 in a mouse model of allergic rhinitis. Furthermore, SoB treatment significantly decreased the increased levels of ovalbumin-specific IgE and improved clinical symptoms and nasal mucosa epithelial morphology in the mouse model of allergic rhinitis. In addition, we further demonstrated that SoB treatment significantly increased the serum levels of IL-2 and IFN-γ and decreased the serum levels of IL-4 and IL-10, correcting the Th1/Th2 imbalance in the mouse model of allergic rhinitis. Taken together, our study suggests that SoB has the potential to treat allergic rhinitis.

    Allergic rhinitis is a global illness with a well-recognised impact on quality of life and work performance. Comparatively little is known about the extent of its economic impact on society. The TOTALL study estimates the total cost of allergic rhinitis using a sample representing the entire Swedish population of working age. A questionnaire focused on allergic rhinitis was mailed out to a random population of Swedish residents, aged 18-65 years. Health-care contacts, medications, absenteeism (absence from work) and presenteeism (reduced working capacity at work) were assessed, and the direct and indirect costs of allergic rhinitis were calculated. Medication use was evaluated in relation to the ARIA guidelines. In all, 3,501 of 8,001 (44%) answered the questionnaire, and 855 (24%) of these reported allergic rhinitis. The mean annual direct and indirect costs because of allergic rhinitis were €210.3 and €750.8, respectively, resulting in a total cost of €961.1 per individual/year. Presenteeism represented 70% of the total cost. Antihistamines appear to be used in excess in relation to topical steroids, and the use of nasal decongestants was alarmingly high. The total cost of allergic rhinitis in Sweden, with a population of 9.5 million, was estimated at €1.3 billion annually. These unexpectedly high costs could be related to the high prevalence of disease, in combination with the previously often underestimated indirect costs. Improved adherence to guidelines might ease the economic burden on society.

    The aim of this study was to assess whether the association with social class differed between allergic rhinitis and asthma and whether these associations have changed over time. The Swedish Military Service Conscription Register was linked to two other national registers for 1,247,038 male conscripts in successive cohorts born between 1952 and 1977. The percentage of asthma cases associated with allergic rhinitis was 15% in the oldest cohort and 44% in the youngest cohort. Low socio-economic status (SES) was associated with an increased risk (assessed as odds ratio) of asthma without allergic rhinitis (1.14, 95% confidence interval (CI) 1.11-1.17) but a slightly reduced risk of asthma with allergic rhinitis (0.96, 95% CI 0.93-1.00). The risk of allergic rhinitis was 0.84, 95% CI 0.82-0.85. A positive interaction between SES and year of birth occurred in all three conditions. Low SES was related to a reduced risk of asthma with allergic rhinitis in the earliest cohort (0.72, 95% CI 0.53-0.82) but a slightly increased risk in the most recent cohort (1.07, 95% CI 1.01-1.14). In conclusion, the role of social class has changed over time. The steepest increase in asthma and allergic rhinitis occurred in conscripts with a low socio-economic status.

    Two experiments were performed during the pollen season to study the activity of different antiallergic drugs in the treatment of seasonal allergic rhinitis. Nasal allergen challenge (NAC) was performed to mimic an acute attack of allergic rhinitis and to objectively evaluate the effect of the drugs on the early-phase reaction during the season. The first study assessed the effect of H1 (Cetirizine 10 mg a day) and of a combination of H1 (Cetirizine 10 mg) plus H2 (Cimetidine 800 mg a day) antagonists on nasal symptoms, mediator release and eosinophil count in a group of 16 patients with seasonal allergic rhinitis. During the same season a second study compared in a randomized way (2 parallel groups) the effect of Budesonide (Rhinocort Aqua) and Azelastine (Allergodil nasal spray) in a group of 14 patients. Results showed that both antihistamines, applied topically of dosed orally, reduced sneezing even when significant increases of histamine concentration in nasal secretions were evidenced immediately after NAC. When a combination of Cetirizine and Cimetidine was administered, a significant (p < 0.01) reduction of nasal airway resistance and increase of nasal airflow after NAC were demonstrated as well. In addition, topical application of Budesonide showed a strong (p < 0.01) effect on the infiltration and activation of eosinophils during the season, and on tryptase release after NAC. These effects lasted at least for one week after therapy.

    Hay fever is a pollen-induced allergic reaction that strongly affects the overall quality of life of many individuals. The disorder may vary in severity and symptoms depending on patient-specific factors such as genetic disposition, individual threshold of pollen concentration levels, medication, former immunotherapy, and others. Thus, information services that improve the quality of life of hay fever sufferers must address the needs of each individual separately. In this paper, we demonstrate the development of information services that offer personalized pollen-induced symptoms forecasts. The backbone of these services consists of data of allergic symptoms reported by the users of the Personal Hay Fever Diary system and pollen concentration levels (European Aeroallergen Network) in several sampling sites. Data were analyzed using computational intelligence methods, resulting in highly customizable forecasting models that offer personalized warnings to users of the Patient Hay Fever Diary system. The overall system performance for the pilot area (Vienna and Lower Austria) reached a correlation coefficient of r = 0.71 ± 0.17 (average ± standard deviation) in a sample of 219 users with major contribution to the Pollen Hay Fever Diary system and an overall performance of r = 0.66 ± 0.18 in a second sample of 393 users, with minor contribution to the system. These findings provide an example of combining data from different sources using advanced data engineering in order to develop innovative e-health services with the capacity to provide more direct and personalized information to allergic rhinitis sufferers.

    Background. Asthma and allergic rhinitis are highly prevalent conditions that cause major illness worldwide. This study aimed to assess the association between allergic rhinitis and asthma control in Peruvian school children. Methods. A cross-sectional study was conducted among 256 children with asthma recruited in 5 schools from Lima and Callao cities. The outcome was asthma control assessed by the asthma control test. A score test for trend of odds was used to evaluate the association between allergic rhinitis severity and the prevalence of inadequate asthma control. A generalized linear regression model was used to estimate the adjusted prevalence ratios of inadequate asthma control. Results. Allergic rhinitis was present in 66.4% of the population with asthma. The trend analysis showed a positive association between allergic rhinitis and the probability of inadequate asthma control (P < 0.001). It was associated with an increased prevalence of inadequate asthma control, with adjusted prevalence ratios of 1.53 (95% confidence interval: 1.19−1.98). Conclusion. This study indicates that allergic rhinitis is associated with an inadequate level of asthma control, giving support to the recommendation of evaluating rhinitis to improve asthma control in children.

    Allergic rhinitis represents a global health issue affecting 10% to 25% of the population worldwide. Over the years, studies have found that allergic diseases, including allergic rhinitis, are associated with immunological responses to antigens driven by a Th2-mediated immune response. Because Toll-like receptors (TLRs) are involved in both innate and adaptive immune responses to a broad variety of antigens, the association between polymorphisms of TLRs and allergic diseases has been the focus in many animal and human studies. Although the etiology of allergic rhinitis is still unknown, extensive research over the years has confirmed that the underlying causes of allergic diseases are due to many genetic and environmental factors, along with the interactions among them, which include gene–environment, gene–gene, and environment–environment interactions. Currently, there is great inconsistency among studies mainly due to differences in genetic background and unique gene–environment interactions. This paper reviews studies focusing on the association between TLR polymorphisms and allergic diseases, including allergic rhinitis, which would help researchers better understand the role of TLR polymorphisms in the development of allergic rhinitis, and ultimately lead to more efficient therapeutic interventions being developed.

    Thirty four patients with allergic rhinitis were included in two randomized groups and treated with Cetirizine and Astemizole respectively, 10 mg/day in oral administration during 15 days. This study was designed in order to compare the efficacy and tolerance of Cetirizine versus Astemizole, with special reference on the collateral effects on the central nervous system. Although both drugs showed good results. Cetirizine had a statistically significant better outcome in the evolution of symptoms, above all at the second day of treatment. Also it showed superior results, based on a subjective approach, related to the rapidity, power and efficacy of its action.

    Background: Xanthii Fructus (XF) is widely used in traditional anti-bacterial and anti-inflammatory Asian medicine. Allergic rhinitis is a common inflammatory disease characterized by markedly increased levels of anti-inflammatory factors and the recruitment of inflammatory cells into the nasal mucosa. We investigated the effects of XF in the allergen-induced rhinitis model. Materials and Methods: Following ovalbumin (OVA)/alum intraperitoneal injection on days 0, 7 and 14, the BALB/c mice (albino, laboratory-bred strain of the house mice) were challenged intranasally with OVA for 10 days a week after the last sensitization. The number of sneezes was recorded for 10 days; additionally, the levels of cytokines, histamine, immunoglobulin E (IgE) and OVA-specific serum IgE were estimated. Eosinophil infiltration, thickness of nasal mucosa and expression of caspase-1 were determined by immunohistochemistry. We also evaluated the effect of XF on the phosphorylation of nuclear factor kappa-B (NF-κB) and inhibitor of nuclear factor kappa B-alpha (IκB-α) in human mast cell-1 (HMC-1), by Western blotting. Results: The administration of XF significantly decreased sneezing and the serum levels of histamine, IgE, OVA-specific IgE, and cytokines such as tumor necrosis factor-alpha (TNF-α), interleukine-1 beta (IL-1β), IL-5, IL-6, monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-2 (MIP-2). XF inhibited the changes in thickness of the nasal septum, influx of eosinophils and expression of capase-1. In addition, XF inhibited the phosphorylation of IκB-α and NF-κB in phorbol-myristate-acetate plus calcium ionophore A23187 (A23187) stimulated HMC-1. Conclusion: This study suggests that XF acts a potent anti-allergic drug which alleviates the allergic responses in ovalbumin-sensitized mouse allergic rhinitis model. PMID:26664025

    Background: Allergic rhinitis (AR) is a common disorder. The diagnosis is based on the concordance between allergy sensitization and history. Serum allergen specific immunoglobulin E (sIgE) assessment allows characterization of the relevant sensitizing allergens. Presently, Allergic Rhinitis and its Impact on Asthma (ARIA) classification subdivides AR based on symptoms severity and duration. However, the relationship between sIgE levels and symptom severity is still a matter of debate. Objective: Therefore, this study aimed at relating sIgE levels with symptom severity assessed by ARIA classification in a group of patients with AR. Methods: We enrolled 217 patients with AR (123 women; median age, 39.5 years). The sIgE levels (expressed in kUA/L) to house-dust mite were detected by the fluorescence enzyme immunoassay in peripheral blood samples. The IgE calibrators were traceable to the second international reference preparation 75/502 of human serum IgE from the World Health Organization. Symptom severity was assessed by ARIA classification. Results: We found a significant difference in sIgE levels in patients with mild intermittent versus mild persistent symptoms (p < 0.05), mild intermittent versus moderate-to-severe persistent symptoms (p < 0.001), moderate-to-severe intermittent versus moderate-to-severe persistent symptoms (p < 0.01), and mild persistent versus moderate-to-severe persistent symptoms (p < 0.05). Conclusion: Analysis of these findings indicated that the sIgE level to house-dust mite might be a reliable biomarker for symptom severity in patients with AR. This outcome might be clinically relevant, particularly in candidates for immunotherapy. PMID:28381320

    The effect of cetirizine on quality of life (QOL) in subjects with perennial allergic rhinitis (PAR) has been previously evaluated using generic instruments. While generic QOL tools are used across various conditions, disease-specific instruments evaluate the impact of treatment on areas that are affected by that particular condition. This study evaluated the effect of cetirizine on symptom severity and health-related QOL, using a disease-specific instrument, in adults with PAR. This randomized, double-blind, placebo-controlled study was conducted at 15 U.S. centers outside the pollen allergy season. After a 1-week placebo run-in period, qualified subjects aged 18-65 years with PAR were randomized to once-daily cetirizine 10 mg (n = 158) or placebo (n = 163) for 4 weeks. Change from baseline in total symptom severity complex (TSSC) and overall Rhinitis Quality of Life Questionnaire (RQLQ) scores were primary efficacy end points. Cetirizine produced significantly greater improvements in mean TSSC for each treatment week (p < 0.05) and for the entire 4-week treatment period (p = 0.005) compared with placebo. After 4 weeks, cetirizine-treated subjects reported significantly greater overall improvement in RQLQ scores compared with placebo-treated subjects (p = 0.004). After 1 week, cetirizine produced significant improvements in the nasal symptoms, practical problems, and activities RQLQ domain scores compared with placebo (p < 0.05). After 4 weeks, cetirizine-treated subjects reported significant reductions in these RQLQ domain scores and in emotion domain scores compared with placebo-treated subjects (p < 0.05). Cetirizine 10 mg daily produced significant improvements in symptom severity and allergic rhinitis-related QOL compared with placebo in adults with PAR.

    The aim of the study was assessment of incidence of allergic rhinitis and respiratory infections and evaluation of quality of life of first grade school age children with allergic rhinitis. The cross sectional study in randomly selected regions and schools was conducted using specially developed parent questionnaire and mini rhino conjunctivitis quality of life questionnaire (MiniRQLQ). On the first was used special questionnaire, and on the second phase MiniRQLQ was used in cases with allergic rhinitis. Total of 1530 parent of 6-8 years children were interviewed, 1499 first phase questionnaires and 174MiniRQLQ were analyzed by SPSS 19 program. From 1499 children 799 (53.3%) were girls and 700 (46.7%) - boys. The 810 (54%) live in urban, 524 (35%) in rural area and 165 (11%) in high mountains. The study revealed that 2.3% of children have respiratory infections 7-8 times per year, 19.9% 3-5 times, 53.4% 1-2 times and 24.2% became ill very rarely. There was statistically significant difference between the frequency of respiratory infection in rural and urban area (p<0,001).The frequency of chronic diseases reported by parents is 18.3% (n=274), from those 201 (73.3%) are allergic disorders (asthma, rhinitis, atopic dermatitis), that is 13.4% of total respondents. The incidence of allergic rhinitis was 11.6%, most frequent symptom was rhinorrhea 168 (11.2%), recurrent sneezing episodes during last year was seen in 153 (10.2%), nasal pruritus was reported in 137 (9.1%), nasal obstruction in 117 (7.8%). The eye symptoms were reported in 62 (4.2%). The symptoms of allergic rhinitis is significantly higher in urban population then in rural area (P<0.02), as well as in boys (P<0.05). The 109 (62.6%) of respondents answer that symptoms and mostly nasal obstruction affected their quality of life, especially on recreational activities and sleep.

    Hemophilic pseudotumor is a rare complication, even in patients with severe hemophilia. Herein we report on a case of hemophilic pseudotumor in a patient with mild hemophilia A and allergic rhinitis, initially suspected to be a nasal tumor. The pseudotumor was cured by supplementation with recombinant factor VIII concentrates, and medication for allergic rhinitis. Pseudotumor should always be considered in hemophiliac patients, even in those with only mild deficiency of coagulation factors.

    This systematic review aims first to summarize the previous areas of application of computational fluid dynamics (CFD) and then to demonstrate that CFD is also a suitable instrument for generating three-dimensional images that depict drug effects on nasal mucosa. Special emphasis is placed on the three-dimensional visualization of the antiobstructive effect of nasal steroids and antihistamines in the treatment of allergic rhinitis. In the beginning, CFD technology was only used to demonstrate physiological and pathophysiological airflow conditions in the nose and to aid in preoperative planning and postoperative monitoring of surgical outcome in the field of rhinosurgery. The first studies using CFD examined nasal respiratory physiology, important functions of the nose, such as conditioning and warming of inspired air, and the influence of pathophysiological changes on nasal breathing. Also, postoperative outcome of surgical procedures could be "predicted" using the nasal airflow model. Later studies focused on the three-dimensional visualization of the effect of nasal sprays in healthy subjects and postoperative patients. A completely new approach, however, was the use of CFD in the area of allergic rhinitis and the treatment of its cardinal symptom of nasal obstruction. In two clinical trials, a suitable patient with a positive history of allergic rhinitis was enrolled during a symptom-free period after the pollen season. The patient developed typical allergic rhinitis symptoms after provocation with birch pollen. The 3-D visualization showed that the antiallergic treatment successfully counteracted the effects of nasal allergen provocation on nasal airflow. These observations were attributed to the antiobstructive effect of a nasal steroid (mometasone furoate) and a systemic antihistamine (levocetirizine), respectively. CFD therefore constitutes a non-invasive, precise, reliable and objective examination procedure for generating three-dimensional images that

    Pattern, or “zheng,” differentiation is the essential guide to treatment with traditional Chinese medicine (TCM). However, the considerable variability between TCM patterns complicates evaluations of TCM treatment effectiveness. The aim of this study was to explore and characterize the relationship between patterns and the core patterns of allergic rhinitis. We summarized 23 clinical trials of allergic rhinitis with mention of pattern differentiation; association rule mining was used to analyze TCM patterns of allergic rhinitis. A total of 205 allergic rhinitis patients seen at Chang Gung Memorial Hospital from March to June 2005 were included for comparison. Among the 23 clinical trials evaluated, lung qi deficiency and spleen qi deficiencies were the core patterns of allergic rhinitis, accounting for 29.50% and 28.98% of all patterns, respectively. A higher prevalence of lung or spleen qi deficiency (93.7%) was found in Taiwan. Additionally, patients with lung or spleen qi deficiency were younger (27.99 ± 12.94 versus 58.54 ± 12.96 years) and the severity of nasal stuffiness was higher than among patients with kidney qi deficiency (1.35 ± 0.89 versus 0.62 ± 0.65; P < 0.05). Lung and spleen qi deficiencies are the core patterns of allergic rhinitis and determining the severity of nasal stuffiness is helpful in differentiating the TCM patterns. PMID:22899954

    Google Trends (GT) is a Web-based surveillance tool used to explore the searching trends of specific queries on Google. Recent studies have suggested the utility of GT in predicting outbreaks of influenza and other diseases. However, this utility has not been thoroughly evaluated for allergic diseases. Therefore, we investigated the utility of GT for predicting the epidemiology of allergic rhinitis. In the USA, GT for allergic rhinitis showed repetitive seasonality that peaked in late April and early May and then rapidly decreased, and a second small peak occurred in September. These trends are highly correlated with the searching trends for other queries such as 'pollen count', antihistamines such as loratadine and cetirizine (all r > 0.88 and all P < 0.001), and even the total pollen count collected from 21 pollen counters across the USA (r = 0.928, P < 0.001). Google Trends for allergic rhinitis was similar to the monthly changes in rhinitis symptoms according to the US National Health and Nutrition Examination Survey III, sales for Claritin(®) and all over-the-counter antihistamines, and the number of monthly page views of 'claritin.com'. In conclusion, GT closely reflects the real-world epidemiology of allergic rhinitis in the USA and could potentially be used as a monitoring tool for allergic rhinitis.

  7. The history and progression of treatments for allergic rhinitis.

    2014-01-01

    This article intends to place new treatments in the context of allergic rhinitis (AR) treatment history. The medical literature was searched for significant advances and changes in AR treatment. Historical data on AR treatment options and management were selected. Reviews of AR management published throughout the 20th century were included to provide context for treatment advances. Modern AR treatment began in the early 20th century with immunotherapy and was soon followed by the emergence of antihistamine therapy in the 1930s. Numerous treatments for AR have been used over the ensuing decades, including decongestants, mast cell stabilizers, and leukotriene receptor antagonists. Topical corticosteroid options were developed the 1950s, and, added to baseline antihistamine therapy, became the foundation of AR treatment. Treatment options were significantly impacted after the 1987 Montreal Protocol, which phased out the use of chlorofluorocarbon propellant aerosols because of environmental concerns. From the mid-1990s until recently, this left only aqueous solution options for intranasal corticosteroids (INSs). The approval of the first hydrofluoroalkane propellant aerosol INSs for AR in 2012 restored a "dry" aerosol treatment option. The first combination intranasal antihistamine/INSs was also approved in 2012, providing a novel treatment option for AR. Treatment of AR has progressed with new therapeutic options now available. This should continue to move forward with agents to alter the allergic mechanism itself and impact the disease burden that has a significant impact on patient outcomes.

    Various diseases of the upper airway, such as acute or chronic sinusitis, otitis media, pharyngitis or laryngitis, snoring and sleep apnea syndrom, may be associated with allergic rhinitis. The relationship between these pathologies and the allergic rhinitis has been well established from a clinical and epidemiological point of view, but the pathophysiological mechanisms remain uncertain. A good knowledge of symptoms and the performance of explorations, such as nasal endoscopy for sinusitis, are important in order to take care of these associated diseases. When upper airway diseases are associated with allergic rhinitis, treatment of rhinitis must generally be reinforced. Treament of associated disease will be specific to each disease, and sometimes surgery is required, specially in case of chronic sinusitis. In all cases, the pneumologist, allergologist and ENT physician should work in close collaboration.

    Background: The sublingual mucosa has been used for many years to apply allergenic extracts for the purpose of specific immunotherapy (IT). Although sublingual IT (SLIT) is both safe and efficacious, the density of antigen-presenting cells is higher in other regions of the oral cavity and vestibule, which make them a potentially desirable target for IT. Objective: To present the concept of oral mucosal IT (OMIT) and to provide pilot data for this extended application of SLIT. Methods: An open-label, 12-month, prospective study was undertaken as a preliminary step before a full-scale clinical investigation. Twenty-four individuals with allergic rhinitis received IT by applying allergenic extracts daily to either the oral vestibule plus oral cavity mucosa by using a glycerin-based toothpaste or to the sublingual mucosa by using 50% glycerin liquid drops. Adverse events, adherence rates, total combined scores, rhinoconjunctivitis quality-of-life questionnaire scores, changes in skin reactivity, and changes in serum antibody levels were measured for each participant. Results: No severe adverse events occurred in either group. The adherence rate was 80% for the OMIT group and 62% for the SLIT group (p = 0.61). Decreased total combined scores were demonstrated for both the OMIT group (15.6%) and the SLIT group (22.3%), although this decrease did not reach statistical significance in either group. Both groups achieved a meaningful clinical improvement of at least 0.5 points on rhinoconjunctivitis quality-of-life questionnaire. A statistically significant rise in specific immunoglobulin G4 (IgG4) was seen in both groups over the first 6 months of treatment. Conclusion: OMIT and SLIT demonstrated similar safety profiles and adherence rates. Measurements of clinical efficacy improved for both groups, but only changes in IgG4 achieved statistical significance. These pilot data provide enough evidence to proceed with a full-scale investigation to explore the role of OMIT in

    Background: The purpose of the study was to determine the age at which initiation of specific subcutaneous immunotherapy (SCIT) becomes more cost-effective than continued lifetime intranasal steroid (NS) therapy in the treatment of allergic rhinitis, with the use of a decision analysis model. Methods: A Markov decision analysis model was created for this study. Economic analyses were performed to identify “break-even” points in the treatment of allergic rhinitis with the use of SCIT and NS. Efficacy rates for therapy and cost data were collected from the published literature. Models in which there was only incomplete improvement while receiving SCIT were also evaluated for economic break-even points. The primary perspective of the study was societal. Results: Multiple break-even point curves were obtained corresponding to various clinical scenarios. For patients with seasonal allergic rhinitis requiring NS (i.e., fluticasone) 6 months per year, the age at which initiation of SCIT provides long-term direct cost advantage is less than 41 years. For patients with perennial rhinitis symptoms requiring year-round NS, the cut-off age for SCIT cost-effectiveness increases to 60 years. Hypothetical subjects who require continued NS treatment (50% reduction of previous dosage) while receiving SCIT also display break-even points, whereby it is economically advantageous to consider allergy referral and SCIT, dependent on the cost of the NS prescribed. Conclusion: The age at which SCIT provides economic advantages over NS in the treatment of allergic rhinitis depends on multiple clinical factors. Decision analysis models can assist the physician in accounting for these factors and customize patient counseling with regard to treatment options. PMID:24717886

    Allergic rhinitis is the most common allergic disease in our country. The epidemiology of allergic rhinitis varies according to the geographic regions of the country. The aim of this study was to find out if it also differs in urban and rural areas of the same region. The study groups were randomly selected in order to sample high school students living in small towns or villages in rural areas and in the city center. Initially the screening questionnaires about allergic rhinitis were responded by the students at school. Then the questionnaires were evaluated. Seven hundred eighty-three students who had a positive questionnaire outcome were underwent an ENT examination. Then skin tests and blood analysis were performed to two hundred forty-six students who were diagnosed as allergic rhinitis clinically. Prick test results was found to be positive 61.8% in urban areas and 46.7% in rural areas. The comparison of the ratios of urban and rural areas was significant. Similar results were obtained in serum specific Ig E analysis. The correlation of specific Ig E levels and skin prick test results was significant in all allergens. Allergic rhinitis is a medical and economic problem all over the world and further epidemiologic investigations should be performed.

    Objective To determine the prevalence and risk factors of allergic rhinitis among bakers in Douala. Design A cross-sectional study; the logistic regression model was use to find the risk factors of allergic rhinitis. Setting The study was conducted in 42 bakeries randomly selected among a total of 151 bakeries in the city of Douala. Participants All bakers who consented to participate in the study between 1 May and 31 July 2013. Outcome measures Allergic rhinitis was the outcome of interest. It was defined as the presence of the following symptoms: itchy nose, rhinorrhea, nasal obstruction and sneezing. Results During the study period, a total of 273 bakers were invited and 229 finally agreed to participate in this study. Males were the most represented gender with 222 (96.9%) participants. The mean age of the participants was 36.29±8.9 years. Smoking was found in 55 participants (24.5%). The symptoms of allergic rhinitis were observed in 24.5% of participants. Work related nasal symptoms were present in 15% of participants. Sensitisation to wheat flour and α-amylase was found in 16.6% and 8.3% of participants, respectively. The Prick test was positive for mites in 12.2% of participants. After multivariate analysis, sensitisation to flour (OR 3.95, 95% CI 1.85 to 8.47) and storage mites (OR 3.44, 95% CI 1.45 to 8.18) were the factors independently associated with symptoms of allergic rhinitis. Conclusions Allergic rhinitis is frequent among bakers in Cameroon. Implementation of preventive measures against inhalation of airborne allergens in bakeries and clinical monitoring of bakers sensitised to wheat flour and mites could help to reduce the prevalence of allergic rhinitis among bakers.

    The aim of our study was the evaluation of the role of these insects as causative agents of perennial rhinitis. We studied 317 subjects of both sexes (175 F and 142 M) living in Naples area and examined consecutively in our Centre for perennial nasal symptoms of suspected IgE mediated aetiology. All patients underwent the following diagnostic procedures: anamnestic procedures by using an internal questionnaire, clinical examination, skin prick test by using commercially available allergenic extracts and an allergenic extract containing the whole bodies of Blattella germanica and orientalis, Periplaneta americana. Blood samples for specific IgE determinations and a rhinologic visit were also carried out in patients with cockroach skin Prick test positivity. 14 of 317 subjects, prevalently young males, presented a skin positivity to cockroach allergens. All patients showed a moderate low degree of cutaneous and a low degree of serologic sensitization to allergens of these insects. Our preliminary data seem to demonstrate a mild role of cockroaches as causative agents of perennial rhinitis in Naples area. Further studies are necessary for a more appropriate knowledge of this allergy.

    Background Allergic rhinitis (AR) is the most common allergic disease but little is known about the difference of local immune responses in children and adults with AR. Objective To compare local immune responses between children and adults with AR and nonallergic rhinitis (NAR), and to investigate whether the association of local and systemic immune responses is different between the two age groups. Methods Fifty-one patients with chronic rhinitis were enrolled and grouped into children (N = 27, mean age 7.2 years) and adults (N = 24, mean age 29.9 years). Diagnosis of AR was based on symptoms, skin prick tests and serum specific IgEs. Nasal lavage (NAL) fluids were collected from all subjects and used to measure the levels of total IgE, specific IgEs to house dust mites (Dp and Df), and cytokines (TNF-α, IL-4, IL-10, IL-17A and IFN-γ). Flow cytometry was used to measure inflammatory cell types in NAL fluids. Results AR had significantly increased local levels of total IgE and specific IgEs to Dp and Df compared with NAR in both age groups (P < 0.05). Nasal eosinophils % (P = 0.01) was significantly increased only in children with AR. Local-systemic correlations of total IgE (r = 0.662, P = 0.000) and eosinophil % (r = 0.461, P = 0.015) between the peripheral blood and NAL fluids were found only in children. Moreover, children had correlations between total IgE and eosinophil % in the peripheral blood (r = 0.629, P = 0.001) and in NAL fluids (r = 0.373, P = 0.061). Conclusion Elevated local IgE is a common feature of AR in children and adults. Local measures in NAR showed naïve state of immune response which disagree with the hypothesis of local allergic rhinitis. Children showed intense local inflammation and close local-systemic interactions compared to adults supporting pediatric AR as a distinct feature. PMID:27281182

    Objective Prevalence of allergies is different around the world. Allergic rhinitis is a common chronic disease in children. Intelligence quotient (IQ) is an indicator of efficacy and many factors including chronic diseases may affect it. This study compares the IQs of children diagnosed with persistent or perennial allergic rhinitis with healthy children. Material & Methods This was a comparative study that was conducted from June 2011–May 2013 in an academic referral clinic. In this study, 90 patients aged 6- to 14-yearsold who were diagnosed with persistent or perennial allergic rhinitis and were compared to 90 age and gender match healthy patients from their respective families. The Wechsler Intelligence Scale for Children was used to divide and calculate overall IQ, verbal IQ, and practical IQ. The t-test and chi square were used to analyze quantitative variables and qualitative variables, respectively. Results In this study, out of total 180 children, 90 (50%) in the case group and 90 children (50%), the control group participated for IQ comparison. One hundred (57%) were male and 80 (43%) were female. The overall IQ for allergic rhinitis patients and healthy patients was 109.2 and 107.5, respectively. This difference was not considered significant. Furthermore, there was no significant difference between the IQ scores of males and females. Conclusion Although allergic rhinitis is a chronic disease and effects quality of life, there were no identifiable negative effects on IQ. PMID:25143773

  16. The anatomical and functional relationship between allergic conjunctivitis and allergic rhinitis

    There are numerous anatomic connections between the allergic conjunctivitis and allergic rhinitis. The most obvious reason is the physical connection via the nasolacrimal apparatus. However, a closer look at innervation, circulatory, lymphatic, and neurogenic systems reveals much more than a physical connection. The eye is richly innervated by parasympathetic nerves that enter the eyes after traveling in conjunction with the parasympathetic input to the nasal cavity. Parasympathetic innervation governing the tear film and nasal secretion can intersect at the pterygopalatine ganglion. Neurogenic inflammation affects both the eye and the nose as evidenced by the presence of the same neurogenic factors. Venous flow is in the SOV area connecting the eye and the nose, once thought to be without valves. In the past, this thinking is the basis for concern about the danger triangle of the face. Recent literature has shown otherwise. Although valves are present, there are still pathways where bidirectional flow exists and a venous connection is made. The most likely area for venous communication is the pterygoid plexus and cavernous sinus. The venous flow and connections also offers a pathway for allergic shiners. Understanding the mutual connections between the nasal mucosa and the ocular surface can also affect treatment strategies. PMID:24498515

    Allergic rhinitis and asthma represent global problems of public health affecting all age groups; asthma and allergic rhinitis frequently coexist in the same patients. In Latin American prevalence of allergic rhinitis, although variable, is very high. Allergic rhinitis and its Impact on Asthma (ARIA) started during a workshop of the World Health Organization performed in 1999 and was published in 2001. ARIA proposed a new classification of allergic rhinitis in intermittent or persistent and mild or moderate-severe. This approach of classification reflects more nearly the impact of allergic rhinitis in patients. In its review of 2010 ARIA developed guidelines for diagnosis and treatment of allergic rhinitis and of clinical practices for management of comorbidities of allergic rhinitis and asthma based on GRADE (Grading of Recommendations, Development and Evaluation). ARIA has been spread and implemented in more than 50 countries. In Latin American an intense activity has been developed to spread these recommendations in almost all the countries of the region and it is important to record the obtained goals in the diffusion and implementation of ARIA, as well as to identify the unsatisfied needs from the clinical, research and implementation points of view. Final objective is to reinforce the priority that allergy and asthma should have, especially in children, in the programs of public health, as they have been prioritized in European Union in 2011.

    Seasonal allergic rhinitis (AR) occurs predominantly as a result of grass pollen allergy. Grass pollen sublingual immunotherapy (SLIT) has been proven effective in treating AR1. SLIT is currently licensed for use in AR with concomitant stable mild asthma. There is evidence that SLIT improves asthma control when primarily used to treat AR2. The aim was to assess the safety of SLIT in patients with severe seasonal allergic rhinitis who have co-existing stable mild asthma. The secondary aim was to determine whether asthma control improved post SLIT. There was no deterioration in asthma control after 6-36 months of SLIT. 27/30 (90%) patients' asthma control remained stable or indeed improved (p < 0.021). Of this 15 (50%) patients' asthma improved. There was no statistically significant change in their asthma pharmacotherapy after SLIT (p = 0.059). In conclusion, grass pollen SLIT is safe and can potentially treat dual allergic rhinitis- mild asthmatic patients.

    Introduction The III Brazilian Consensus on Rhinitis (2012) defines allergic rhinitis as a nasal mucosa inflammation, mediated by immunoglobulin E, after exposure to allergens. The classic signs and symptoms of allergic rhinitis are nasal obstruction, watery rhinorrhea, sneezing, and nasal itching, often reversible either spontaneously or with treatment, and mouth breathing (breathing predominantly through the mouth, regardless of the cause, due to a nasal breathing impairment) in some cases. Objective To evaluate the literature on masticatory changes in children with mouth breathing due to allergic rhinitis. Methods We conducted a search of the past 10 years, at Bireme and MEDLINE databases, for articles that covered masticatory changes in children with mouth breathing secondary to allergic rhinitis. Results We found 1,986 articles, including 15 repeated in databases, but only two articles met the inclusion criteria fully. Discussion We found few studies to answer the question raised in this review, and those studies have some methodological limitations. Most articles claimed no have statistically significant differences in masticatory changes in this population. Conclusion A better controlled study (isolating diseases, exposure time), with a larger sample (sample calculation appropriate), would be necessary to examine such changes. PMID:25992077

    Allergic rhinitis (AR) is a common chronic condition in children and may impact a child's quality of life. Increasing treatment compliance may improve quality of life. An oral suspension of fexofenadine hydrochloride (HCl) has been developed to ease administration to children and may, therefore, improve treatment compliance. The purpose of this study was to assess the pharmacokinetic behavior, safety, and tolerability of a single dose of fexofenadine HCl oral suspension administered to children aged 2-5 years with allergic rhinitis. Children (aged 2-5 years) with AR were recruited in a multicenter, open-label, single-dose study. Fexofenadine HCl (30 mg) was administered as a 6-mg/mL suspension (5 mL). Plasma samples were collected up to 24 hours postdose. Adverse events (AEs); electrocardiograms (ECGs); vital signs; and clinical laboratory tests for hematology, blood chemistry, and urinalysis were analyzed to evaluate safety and tolerability. Fifty subjects completed the study. Mean maximum plasma concentration of fexofenadine was 224 ng/mL, and mean area under the plasma concentration curve was 898 ng . hour/mL. Treatment-emergent AEs were mild in intensity and reported in a total of seven subjects. No trends or clinically meaningful changes in mean ECG, vital sign, or clinical laboratory test data occurred during the study. In children aged 2-5 years, the exposure after a 30-mg dose of fexofenadine HCl suspension was similar to the exposures previously seen after a 30- and 60-mg dose of fexofenadine HCl in children aged 6-11 years and in adults, respectively. The suspension was also well tolerated.

    Introduction: Submucoperichondrial injection of botulinum neurotoxin A (BTA) in the nasal septum is a promising therapeutic option in the treatment of persistent allergic rhinitis (AR) and non-allergic rhinitis, and is safer and more effective than intraturbinate injection in reducing clinical symptoms. Materials and Methods: Forty patients diagnosed with persistent AR or non-allergic rhinitis referred to Shafa Medical Center affiliated to Kerman University of Medical Sciences were included in this study and were randomly allocated to the intervention or control groups. Patients received an injection of 80 units BTA (Dysport, Ipsen Ltd Company, UK) at a concentration of 200 mU/ml in normal saline on four spots in each side of the nose and were followed for 12 weeks. Data were analyzed using a chi-square or Fisher’s test, and Mann Whitney U test. Results: The mean age of patients was 46.1±15.3 years, and the two groups did not differ significantly in demographic variables. The severity of rhinitis symptoms was reduced after 4 weeks of injections in the intervention group and then gradually decreased further until the 12th week. There was a statistically significant difference between the groups (P<0.05). No adverse effects were reported. Conclusion: Submucoperichondrial BTA injection can be considered an effective therapeutic option in patients with persistent AR and idiopathic rhinitis. In comparison with other injection techniques, submucoperichondrial BTA injection has fewer side effects with a longer period of effectiveness, and is easy to perform and is more tolerable for the patient.

    Treatment of allergic vasomotor rhinitis is to be regarded with the factors that modify the symptomatology. In fact must be considered the morphological changes (septum deviation, adenoids, turbinates hypertrophy, polyps) infections (bacteria, chlamydiae, micetes) and specific allergens. Identification of allergens and sensitization threshold is to be studied; then specific hyposensitization will be assessed. In the present study, 68 subjects having nasal reactivity have been observed and underwent to different ways of treatment: 18 with permanent stenosis identified by rhinomanometry and not modified with vasoconstrictors were operated; 25 of the 50 patients with normal nasal cavities showed contemporary infections: after a specific antimicrobic or antimycotic treatment, a clear improvement was obtained documented by rhinomanometry before and after nasal stimulations. The 50 patients with normal morphology underwent a local hyposensitization against the allergens. As a matter of fact: a) in all cases a clear improvement was obtained in phase of increasing; b) after one year of maintainance just 13 over 50 (26%) returned to previous conditions. The Authors remark how local immunotherapy by the nasal way give good possibilities in a high percentage of cases in the following conditions: correct clinical evaluation, especially concerning the identification of factors determining vasomotor rhinitis; employment of precise techniques for diagnosis; observation of clinical data and results turning out from instrumental investigations, especially concerning the nasal provocation test evaluated by rhinomanometry.

    Allergic rhinitis and urticaria are common allergic diseases that may have a major negative impact on patients’ quality of life. Bilastine, a novel new-generation antihistamine that is highly selective for the H1 histamine receptor, has a rapid onset and prolonged duration of action. This agent does not interact with the cytochrome P450 system and does not undergo significant metabolism in humans, suggesting that it has very low potential for drug–drug interactions, and does not require dose adjustment in renal impairment. As bilastine is not metabolized and is excreted largely unchanged, hepatic impairment is not expected to increase systemic exposure above the drug’s safety margin. Bilastine has demonstrated similar efficacy to cetirizine and desloratadine in patients with seasonal allergic rhinitis and, in a Vienna Chamber study, a potentially longer duration of action than fexofenadine in patients with asymptomatic seasonal allergic rhinitis. It has also shown significant efficacy (similar to that of cetirizine) and safety in the long-term treatment of perennial allergic rhinitis. Bilastine showed similar efficacy to levocetirizine in patients with chronic spontaneous urticaria and can be safely used at doses of up to fourfold higher than standard dosage (80 mg once daily). The fourfold higher than standard dose is specified as an acceptable second-line treatment option for urticaria in international guidelines. Bilastine is generally well tolerated, both at standard and at supratherapeutic doses, appears to have less sedative potential than other second-generation antihistamines, and has no cardiotoxicity. Based on its pharmacokinetic properties, efficacy, and tolerability profile, bilastine will be valuable in the management of allergic rhinitis and urticaria. PMID:27110120

    The symptoms of allergic rhinitis vary in severity over the course of the day and often are worse in the morning. This review focuses on data from clinical studies of the antihistamine desloratadine to establish whether it effectively controls the morning symptoms of allergic rhinitis. Studies of desloratadine in patients with allergic rhinitis that used instantaneous scoring to assess the severity of morning symptoms were selected for inclusion from published literature (peer-reviewed articles and abstracts presented at professional meetings). When administered once daily, desloratadine is effective in alleviating the morning symptoms of allergic rhinitis, including nasal congestion. Its action is sustained over the 24-hour dosing interval. A comparison of morning and evening dosing of desloratadine revealed equivalent relief of morning symptoms, illustrating that the effect of desloratadine is independent of the time of dosing. Clinical studies indicate that desloratadine is nonsedating and well tolerated, with no evidence of adverse cardiac effects. For many patients with allergic rhinitis, symptoms are most severe in the morning. To maximize the benefits for patients, pharmacologic agents used in the management of allergic rhinitis should be effective in controlling these peak morning symptoms. The sustained 24-hour action of desloratadine and its effective control of morning symptoms make it a valuable tool for improving the quality of life of patients with allergic rhinitis.

    Allergic rhinitis is one of the most common health problems and has a major effect on quality of life. Although new-generation antihistamines and nasal steroids are the main treatment options, complete resolution cannot be obtained in some patients. Besides common side effects such as nasal irritation and epistaxis, the use of these drugs is controversial in some patients, such as pregnant or breastfeeding women. These findings highlight the need for new treatment options. Although phototherapy has been successfully used in the treatment of atopic dermatitis, which is an IgE-mediated disease and shares several common pathogenic features with allergic rhinitis, there are limited studies about its role in the treatment of allergic rhinitis. In this study, we aimed to evaluate and compare the histopathological effects of intranasal phototherapy (Rhinolight) and nasal corticosteroid treatment on the nasal mucosa in allergic rhinitis in a rabbit model and we found that both treatment options significantly reduced inflammation in the nasal mucosa without increasing apoptosis of mucosal cells.

    We aimed to evaluate the effect of chronic hypergravity in a mouse model of allergic asthma and rhinitis. Forty BALB/c mice were divided as: group A (n = 10, control) sensitized and challenged with saline, group B (n = 10, asthma) challenged by intraperitoneal and intranasal ovalbumin (OVA) to induce allergic asthma and rhinitis, and groups C (n = 10, asthma/rotatory control) and D (n = 10, asthma/hypergravity) exposed to 4 weeks of rotation with normogravity (1G) or hypergravity (5G) during induction of asthma/rhinitis. Group D showed significantly decreased eosinophils, neutrophils, and lymphocytes in their BAL fluid compared with groups B and C (p < 0.05). In real-time polymerase chain reaction using lung homogenate, the expression of IL-1β was significantly upregulated (p < 0.001) and IL-4 and IL-10 significantly downregulated (p < 0.05) in group D. Infiltration of inflammatory cells into lung parenchyma and turbinate, and the thickness of respiratory epithelium was significantly reduced in group D (p < 0.05). The expression of Bcl-2 and heme oxygenase-1 were significantly downregulated, Bax and extracellular dismutase significantly upregulated in Group D. Therefore, chronic hypergravity could have a hormetic effect for allergic asthma and rhinitis via regulation of genes involved in antioxidative and proapoptotic pathways. It is possible that we could use hypergravity machinery for treating allergic respiratory disorders. PMID:27251783

    BACKGROUND Specific patterns of allergic sensitization as well as quantification of the in vitro IgE response in early life may provide relevant clinical insight into future rhinitis and asthma risk. OBJECTIVE To define relationships among established sensitization to particular aeroallergens, quantitative analyses of allergen-specific IgE levels, pet exposure and sensitization, and asthma and rhinitis risk. METHODS Children at high-risk for the development of asthma and allergic diseases were enrolled at birth into the Childhood Origins of ASThma (COAST) study. Allergen-specific IgE was assessed at ages 1, 3, 6, and 9 years by fluoroenzyme immunoassay (Unicap® 100, Pharmacia Diagnostics). Current asthma and rhinitis were diagnosed at age 6 and 8 years. RESULTS Sensitization to dog was strongly associated with increased asthma risk (p < 0.0001). Sensitization to perennial compared to seasonal allergens was more strongly associated with asthma risk, while sensitization to seasonal allergens was more closely associated with rhinitis risk. Increased levels of specific IgE to perennial allergens were associated with an increased asthma risk (p = 0.05), while any detectable level of IgE to seasonal allergens was associated with increased rhinitis risk (p = 0.0009). While dog and cat sensitization were both independently associated with increased asthma and rhinitis risk, dog exposure at birth was associated with a reduced risk of asthma, regardless of dog sensitization status during the first 6 years of life (p = 0.05). CONCLUSIONS & CLINICAL RELEVANCE Analyzing specific patterns of an individual’s allergic sensitization profile reveals additional relevant associations with asthma and rhinitis risk as opposed to the information gained from characterizing an individual as “atopic” by the presence of any demonstrable sensitization alone. Further, protective mechanisms of dog exposure with regards to asthma risk appear to be unrelated to the prevention of

    Tyrophagus putrescentiae and Dermatophagoides pteronyssinus are causative factors for the development of airway hypersensitivity. The main objective in this study was to identify the cross-reactive allergens between T. putrescentiae and D. pteronyssinus and investigate their sensitization in patients with allergic rhinitis. The prevalence of sensitization to mites was determined by skin prick tests and histamine release assays. Both immunoblot and ELISA inhibition assays were performed by using the recombinant allergens of T. putrescentiae and D. pteronyssinus. The cross-reactive allergens were identified by using IgE-binding inhibition analysis. The correlations of specific IgE between T. putrescentiae and D. pteronyssinus to group 2 and group 3 mite allergens were compared. A total of 117 allergic rhinitis patients, aged between 16 and 40 years old were recruited to be included in this study. The results showed that 70% (82/117) of allergic rhinitis subjects had skin test positive reactions to D. pteronyssinus or T. putrescentiae. Among these mite-sensitive subjects, there were 81 subjects (81/82) sensitive to D. pteronyssinus and 34 subjects (34/82) sensitive to T. putrescentiae. Among the T. putrescentiae hypersensitive subjects, 97% (33/34) were also sensitized to D. pteronyssinus. In the IgE-binding inhibition analysis, 59% (13/22) subjects had IgE-binding activity of T. putrescentiae that was completely absorbed by D. pteronyssinus, especially components with MW at 16 kDa. In ELISA inhibition testing, 69% of IgE-binding was inhibited by rTyr p 2, and 45% inhibited by rTyr p 3. The titers of IgE antibodies to rTyr p 2 and rDer p 2 were well correlated, but not rTyr p 3 and rDer p 3. In conclusion, most T. putrescentiae sensitized subjects were also sensitized to D. pteronyssinus in young adult allergic rhinitis patients. The complete absorption of IgE binding activity by D. pteronyssinus indicates that T. putrescentiae hypersensitivity might be due to the

    Several studies have reported negative relations between allergic diseases and school performance but have not simultaneously considered various allergic diseases, including allergic rhinitis, asthma, and atopic dermatitis, and only examined a limited number of participants. The present study investigated the associations of allergic rhinitis, asthma, and atopic dermatitis with school performance in a large, representative Korean adolescent population. A total of 299,695 7th through 12th grade students participated in the Korea Youth Risk Behaviour Web-based Survey (KYRBWS) from 2009 to 2013. The subjects’ history of allergic rhinitis, asthma, and atopic dermatitis and number of school absences due to these diseases in the previous 12 months were examined and compared. School performance was classified into 5 levels. The relations between allergic disorders and school performance were analyzed using multiple logistic regressions with complex sampling and adjusted for the subjects’ durations of sleep, days of physical activity, body mass indexes (BMIs), regions of residence, economic levels, parents’ education levels, stress levels, smoking status, and alcohol use. A subgroup analysis of the economic groups was performed. Allergic rhinitis was positively correlated with better school performance in a dose-dependent manner (adjusted odds ratios, AOR, [95% confidence interval, CI] = 1.50 [1.43–1.56 > 1.33 [1.28–1.38] > 1.17 [1.13–1.22] > 1.09 [1.05–1.14] for grades A > B > C > D; P < 0.001). Asthma was negatively correlated with better school performance (AOR [95% CI] = 0.74 [0.66–0.83], 0.87 [0.79–0.96], 0.83 [0.75–0.91], 0.93 [0.85–1.02] for performance A, B, C, and D, respectively; P < 0.001). Atopic dermatitis was not significantly correlated with school performance. The subgroup analysis of the students’ economic levels revealed associations between allergic diseases and school performance. Compared to other allergic disorders, the asthma

    The objective of this study was to evaluate the selected oxidative stress parameters in 50 (35 males, 15 females) pediatric patients aged from 3 to 10 years diagnosed with perennial allergic rhinitis before and after the two-month treatment with desloratadine at the dose of 5 mg/day and in 11 healthy individuals. Oxidative stress was determined by the analysis of the reactive oxygen species neutralizing enzyme activity in erythrocytes superoxide dismutase and catalase, the estimation of free radical processes intensity: content of malondialdehyde in erythrocytes and the level of plasma hydroperoxides as well as by quantification of the plasma total antioxidant status. Changes in the studied parameters in untreated perennial allergic rhinitis patients indicate increased oxidative stress. The treatment with desloratadine normalized the superoxide dismutase and catalase activity as well as the malondialdehyde formation. The plasma hydroperoxides level in treated patients with perennial allergic rhinitis is reduced as compared with untreated subjects, although still higher than in the control. Desloratadine caused an increase in the total antioxidant status level, but it was not statistically significant. It can be concluded that oxidative stress is implicated in the pathogenesis of perennial allergic rhinitis. The results demonstrate that desloratadine exerts antioxidant effects in vivo.

    We studied the respiratory responses to an increase in airway temperature in patients with allergic rhinitis (AR). Responses to isocapnic hyperventilation (40% of maximal voluntary ventilation) for 4min of humidified hot air (HA; 49°C) and room air (RA; 21°C) were compared between AR patients (n=7) and healthy subjects (n=6). In AR patients, cough frequency increased pronouncedly from 0.10±0.07 before to 2.37±0.73 during, and 1.80±0.79coughs/min for the first 8min after the HA challenge, but not during the RA challenge. In contrast, neither HA nor RA had any significant tussive effect in healthy subjects. The HA challenge also caused respiratory discomfort (mainly throat irritation) measured by the handgrip dynamometry in AR patients, but not in healthy subjects. Bronchoconstriction was not detected after the HA challenge in either group of subjects. In conclusion, hyperventilation of HA triggered vigorous cough response and throat irritation in AR patients, indicating the involvement of sensory nerves innervating upper airways.

    Aim To identify pollen types in southern Croatia and investigate the impact of sensitization to Ambrosia elatior (A. elatior) on symptoms and treatment of patients with seasonal allergic rhinitis and/or asthma. Methods The study recruited 120 patients from Split-Dalmatian County with seasonal rhinitis and asthma symptoms and positive skin prick test to one or more common inhaled allergens. Patients with positive skin prick test and increased specific IgE to A. elatior (n = 56) were included in the follow-up study during the A. elatior pollen season. Rhinitis and asthma symptoms were scored and drug treatment recorded using standardized questionnaires. Also, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), and eosinophil count in peripheral blood were measured. Type and pollen concentration of A. elatior in the air over the nine-week pollen season were determined on the glass slides using the gravimetric method. The results were expressed as the proportion of A. elatior pollen in the total pollen. Results Fifty-six of 120 patients (46.7%) were sensitized to A. elatior. Its proportion in total pollen peaked to 12% in the first week of September. Forty-one patients who completed the follow-up study showed a significantly higher score of symptoms during this peak period than in the beginning of the pollen season for seasonal allergic rhinitis (median±interquartile range, 50 ± 11 vs 7 ± 4; P<0.001) and for seasonal allergic asthma (median±interquartile range, 12 ± 2 vs 0 ± 0; P<0.001). Conclusion A. elatior is an important cause of seasonal allergic rhinitis and asthma and must be included in the routine diagnostic procedures in southern Croatia. PMID:17309141

  19. Effectiveness of twice daily azelastine nasal spray in patients with seasonal allergic rhinitis

    2008-01-01

    Azelastine nasal spray (Allergodil®, Lastin®, Afluon®; Meda AB, Stockholm, Sweden) is a fast-acting, efficacious and well-tolerated H1-receptor antagonist for the treatment of rhinitis. In addition it also has mast-cell stabilizing and anti-inflammatory properties, reducing the concentration of leukotrienes, kinins and platelet activating factor in vitro and in vivo, as well as inflammatory cell migration in rhinitis patients. Well-controlled studies in patients with seasonal allergic rhinitis (SAR), perennial rhinitis (PR) or vasomotor rhinitis (VMR) confirm that azelastine nasal spray has a rapid onset of action, and improves nasal symptoms associated with rhinitis such as nasal congestion and post-nasal drip. Azelastine nasal spray is effective at the lower dose of 1 spray as well at a dose of 2 sprays per nostril twice daily, but with an improved tolerability profile compared to the 2-spray per nostril twice daily regimen. Compared with intranasal corticosteroids, azelastine nasal spray has a faster onset of action and a better safety profile, showing at least comparable efficacy with fluticasone propionate (Flonase®; GSK, USA), and a superior efficacy to mometasone furoate (Nasonex®; Schering Plough, USA). In combination with fluticasone propionate, azelastine nasal spray exhibits greater efficacy than either agent used alone, and this combination may provide benefit for patients with difficult to treat seasonal allergic rhinitis. In addition, azelastine nasal spray can be used on an as-needed basis without compromising clinical efficacy. Compared with oral antihistamines, azelastine nasal spray also demonstrates superior efficacy and a more rapid onset of action, and is effective even in patients who did not respond to previous oral antihistamine therapy. Unlike most oral antihistamines, azelastine nasal spray is effective in alleviating nasal congestion, a particularly bothersome symptom for rhinitis sufferers. Azelastine nasal spray is well tolerated

    Cats (Felis domesticus) are rich source of airborne allergens that prevailed in the environment and sensitized a number of people to allergy. In this study, a mouse model of allergic rhinitis caused by the cat allergens was developed for the first time and the model was used for testing therapeutic efficacy of a novel intranasal liposome-entrapped vaccines made of native Fel d 1 (major cat allergen) in comparison with the vaccine made of crude cat hair extract (cCE). BALB/c mice were sensitized with cCE mixed with alum intraperitoneally and intranasally. The allergic mice were treated with eight doses of either liposome (L)-entrapped native Fel d 1 (L-nFD1), L-cCE), or placebo on every alternate day. Vaccine efficacy evaluation was performed one day after provoking the treated mice with aerosolic cCE. All allergenized mice developed histological features of allergic rhinitis with rises of serum specific-IgE and Th2 cytokine gene expression. Serum IgE and intranasal mucus production of allergic mice reduced significantly after vaccination in comparison with the placebo mice. The vaccines also caused a shift of the Th2 response (reduction of Th2 cytokine expressions) towards the non-pathogenic responses: Th1 (down-regulation of the Th1 suppressive cytokine gene, IL-35) and Treg (up-regulation of IL-10 and TGF-β). In conclusions, a mouse model of allergic rhinitis to cat allergens was successfully developed. The intranasal, liposome-adjuvanted vaccines, especially the refined single allergen formulation, assuaged the allergic manifestations in the modeled mice. The prototype vaccine is worthwhile testing further for clinical use in the pet allergic patients. PMID:26954254

    Spirulina represents a blue-green alga that is widely produced and commercialized as a dietary supplement for modulating immune functions, as well as ameliorating a variety of diseases. We have previously shown that the in vitro culture of Spirulina with human peripheral blood mononuclear cells (PBMCs) modulated the production of cytokines. In the present study, we evaluated the impact of a Spirulina-based dietary supplement (Earthrise Nutritionals, Inc., Irvine, CA) on patients with allergic rhinitis by assessing the production of cytokines [interleukin (IL)-4, interferon (IFN)-gamma, and IL-2] critical in regulating immunoglobulin E-mediated allergy. In a randomized double-blinded crossover study versus placebo, allergic individuals were fed daily with either placebo or Spirulina, at 1,000 mg or 2,000 mg, for 12 weeks. PBMCs isolated before and after the Spirulina feeding were stimulated with phytohemagglutinin (PHA) prior to determining the levels of cytokine from cell culture supernatants. Although Spirulina seemed to be ineffective at modulating the secretion of Th1 cytokines (IFN-gamma and IL-2), we discovered that Spirulina, administered at 2,000 mg/day, significantly reduced IL-4 levels by 32% from PHA-stimulated cells. These results indicate that Spirulina can modulate the Th profile in patients with allergic rhinitis by suppressing the differentiation of Th2 cells mediated, in part, by inhibiting the production of IL-4. To our knowledge, this is the first human feeding study that demonstrates the protective effects of Spirulina towards allergic rhinitis.

    The aim of this study is to investigate the association of allergic rhinitis in female university students with socio-economic factors and sex-hormone markers, including age at menarche, menstrual disorders, and selected anthropometrics indexes. The research was conducted among 640 female university students, aged 19-25 years. The measurements of body height, body mass, waist and hip circumference were taken. Each person completed a questionnaire. The occurrence of allergy was determined on the basis of answers to the questions whether the allergy and its allergens were defined on the basis of medical workup. We found that a significantly larger number of cases of allergic rhinitis were recorded in the university students coming from families of high socio-economic level than those from lower level. Allergic rhinitis also was more frequent in the students who spent their childhood in cities than in those who lived in the countryside. The prevalence of allergic rhinitis was inversely correlated to the number of siblings. There were no differences in the prevalence of allergic rhinitis in relation to the birth order. The estrogen level seemed unassociated with rhinitis. However, there were slightly more allergic among females with an earlier age of menarche.

    Meteorological and environmental factors influence the pathogenesis of allergic rhinitis (AR). An understanding of the risk factors will facilitate the development of diagnostic and preventative tools for AR children and improve their quality of life. However, research on the impact of these factors on subjective symptoms in AR children remains scarce. This study explored the relationships between subjective symptoms in pollen and dust mite positive AR children, and meteorological and environmental factors. Using a linear mixed effect model, we analyzed the correlations between monthly data on the subjective symptoms of 351 AR children (from the Shanghai Children's Medical Center) and meteorological and environmental factors during 2013. The monthly meteorological and environmental data were provided by the Shanghai Meteorological Service and Shanghai Environmental Protection Bureau. Temperature and humidity were negatively correlated with the subjective symptom score, with a 0.04 point increase observed for every 1 °C decrease in temperature (P < 0.0001) or 10 % decline in humidity (P = 0.0412). The particulate matter (PM) 10 and PM2.5 concentrations were positively correlated with the subjective symptom score, with a 10 μg/m3 increase in PM10 and PM2.5 yielding a 0.02 (P = 0.0235) and 0.03 (P = 0.0281) increase in the subjective symptom score, respectively. In conclusion, meteorological and environmental factors were correlated with subjective symptoms in AR children. Low temperatures, lower humidity, and high PM10 and PM2.5 concentrations aggravated subjective symptoms in AR children.

    Currently available second-generation H1-antihistamines include a wide group of drugs with a better therapeutic index (or risk-benefit ratio) than the classic antihistamines, although their properties and safety profiles may differ. Bilastine is a newly registered H1-antihistamine for the oral treatment of allergic rhinitis and urticaria, with established antihistaminic and antiallergic properties. Clinical studies in allergic rhinitis and chronic urticaria show that once-daily treatment with bilastine 20 mg is effective in managing symptoms and improving patient's quality of life, with at least comparable efficacy to other nonsedative H1-antihistamines. As far as studies in healthy volunteers, clinical assays and clinical experience can establish, bilastine's safety profile is satisfactory, since it lacks anticholinergic effects, does not impair psychomotor performance or actual driving, and appears to be entirely free from cardiovascular effects.

    Sublingual immunotherapy has been considered to be a painless and effective therapeutic treatment for allergic rhinitis, and is known as type 1 allergy of the nasal mucosa. So far, its mechanism of action has been elucidated employing peripheral blood serum and lymphocytes in an antigen-specific fashion. Because of the limitations in sampling human materials, there is still controversy among many reports between clinical efficacy and laboratory data. Therefore, its mechanism of action needs to be investigated further by using promising animal models such as rodents and monkeys. Bearing this in mind, in our present study, we successfully constructed an effective murine model for sublingual immunotherapy in allergic rhinitis in which mice were administered ovalbumin (OVA) sublingually followed by intraperitoneal sensitization and nasal challenge.

    Upper respiratory infections and allergic rhinitis are common diseases in children. In recent years, U.S. Food and Drug Administration has been promoting pediatric drug development with marketing exclusivity incentives and requirements. The assessment of clinical pharmacology, efficacy, and safety data has facilitated pediatric drug development and provided appropriate labeling for pediatric use. Regulatory decision making involves multiple evaluation processes, including drug exposure comparison between adult and pediatric population, formulation bridging, dose selection, and evaluation of efficacy and safety in pediatric patients. This article reviews the pediatric drugs indicated for cough, cold, and allergic rhinitis, focusing on the utility of clinical pharmacology, safety, and efficacy data in determining the pediatric dosing regimen and the approaches taken for regulatory decision making.

    The aim of this open study was to evaluate the efficacy and safety of new topical corticosteroid Nasonex (mometasone furoate) in allergic, seasonal rhinitis. The investigations were carried out on 30 patients with proven grass pollen allergy. Nasonex was administered intranasally during the pollen season, in a single dose 200 micrograms. During the 3 subsequent visits nasal and nonnasal symptom (total and individual) scores and patient reaction to the treatment were evaluated. Rhinomanometry and number of eosinophils in nasal smear were calculated before and after the treatment. Complete or marked relief of symptoms was observed in 24 patients, moderate improvement in 4 patients and no positive reaction in 2 cases. Nasonex markedly inhibited eosinophil influx to the nasal mucosa. No adverse reaction was observed during 2-week Nasonex treatment. We conclude that Nasonex aerosol is a very effective and well tolerated drug in the treatment of seasonal allergic rhinitis.

    Allergic rhinitis (AR) is a chronic inflammatory respiratory disease affecting 5%–50% of the worldwide population and its prevalence is increasing (Herman 2007). In addition, AR is associated with asthma and other co-morbidities such as conjunctivitis and sinusitis. The main symptoms are nasal congestion, rhinorrea, sneezing, itching, and post-nasal drainage induced after allergen exposure by an IgE-mediated inflammation of the membranes lining the nose. AR is not a life-threatening disease, but it has been shown to have a significant impact on quality of life. The Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines propose a classification of AR in intermittent and persistent, each graded as mild or moderate-severe, and provide a stepwise approach to the treatment. Inhaled steroids and antihistamine are the main tools in AR therapy but more safe and effective drugs are, however, needed. Inhaled steroid ciclesonide appears to be safe and effective.

    Allergic rhinitis is one of the most common diseases of adult and pediatric age, associated with grass pollen (GP) allergy in >50% cases, with a consistent impact on quality of life of affected patients. A grass allergen tablet, containing standardized extract derived from Timothy grass (Phleum pratense) pollen and ~15 μg major allergen P. pratense (rPhl p 5), may be the future of allergen-specific immunotherapy (IT) for GP allergy. The aim of this review was to critically evaluate the role of Timothy GP extract IT for the management of allergic rhinitis. For this purpose, we have tried to analyze potential mechanisms of action at the basis of Timothy GP extract, we have reviewed efficacy studies to establish potential benefits and clinical response, and we have also evaluated safety and tolerability profiles and patient focus perspective, such as quality of life, satisfaction and acceptability, and compliance to this IT.

    We studied the effect of Brazilian propolis on sneezing and nasal rubbing in experimental allergic rhinitis of mice. A single administration of propolis caused no significant effect on both antigen-induced nasal rubbing and sneezing at a dose of 1000 mg/kg, but a significant inhibition was observed after repeated administration for 2 weeks at this dose. Propolis caused no significant inhibitory effect on the production of total IgE level after repeated administration of 1000 mg/kg. The drug also caused no significant inhibition of histamine-induced nasal rubbing and sneezing at a dose of 1000 mg/kg. On the other hand, propolis significantly inhibited histamine release from rat mast cells induced by antigen and compound 48/80 at a concentration of more than 10 microg/ml. These results clearly demonstrated that propolis may be effective in the relief of symptoms of allergic rhinitis through inhibition of histamine release.

    Most up-to-data data from the literature, as well as our experience gained during the routine clinical practice, led us to investigate the incidence of sensibilization on the cockroaches, as well as its role in development of allergic rhinitis. The study included 46 patients with chronic rhinitis. Out of that number, 11 were sensibilized to cockroach extract, while in another 8 senzibilized patients, allergic rhinitis, induced by the same allergen, was evidenced as well. According to this study, we have concluded that in our conditions, cockroach is to be considered significant factor of sensibilization which is to be included into the standard set of inhalation allergens for skin tests.

    Allergic rhinitis (AR) is caused by an IgE-mediated inflammatory reaction. Non-allergic rhinitis (NAR) is characterized by a non-IgE-mediated pathogenesis. Frequently, patients have the two disorders associated: such as mixed rhinitis (MR). Hyaluronic acid (HA) is a fundamental component of the human connective tissue. HA may exert anti-inflammatory and immune-modulating activities. Recently, an intranasal HA formulation was proposed: a supramolecular system containing lysine hyaluronate, thymine and sodium chloride (T-LysYal®). This randomized study investigated whether intranasal T-LysYal® (rinoLysYal®, Farmigea, Italy) was able to reduce symptom severity, endoscopic features, and nasal cytology in 89 patients (48 males and 41 females, mean age 36.3±7.1 years) with AR, NAR, and MR. Patients were treated with intranasal T-LysYal® or isotonic saline solution as adjunctive therapy to nasal corticosteroid and oral antihistamine for 4 weeks. Patients were visited at baseline, after treatment and after 4-week follow-up. Intranasal T-LysYal® treatment significantly reduced the quote of patients with symptoms, endoscopic features, and inflammatory cells. In conclusion, the present study demonstrates that intranasal T-LysYal® is able, as ancillary therapy, to significantly improve patients with AR, NAR, and MR, and its effect is long lasting.

    Background: Corticosteroid nasal sprays are the mainstay of treatment for allergic rhinitis. These sprays have sensory attributes such as scent and/or odor, taste and aftertaste, and run down the throat and/or the nose, which, when unpleasant, can affect patient preference for, and compliance with, treatment. Objective: This study examined patient preference for fluticasone furoate nasal spray (FFNS) or mometasone furoate nasal spray (MFNS) based on their sensory attributes after administration in patients with allergic rhinitis. Methods: This was a multicenter, randomized, double-blind, cross-over study. Patient preferences were determined by using three questionnaires (Overall Preference, Immediate Attributes, and Delayed Attributes). Results: Overall, 56% of patients stated a preference for FFNS versus 32% for MFNS (p < 0.001); the remaining 12% stated no preference. More patients stated a preference for FFNS versus MFNS for the attributes of “less drip down the throat” (p < 0.001), “less run out of the nose” (p < 0.05), “more soothing” (p < 0.05), and “less irritating” (p < 0.001). More patients responded in favor of FFNS versus MFNS for the immediate attributes, “run down the throat” (p < 0.001), and “run out of the nose” (p < 0.001), and, in the delayed attributes, “run down the throat” (p < 0.001), “run out of the nose” (p < 0.01), “presence of aftertaste” (p < 0.01), and “no nasal irritation” (p < 0.001). Conclusion: Patients with allergic rhinitis preferred FFNS versus MFNS overall and based on a number of individual attributes, including “less drip down the throat,” “less run out of the nose,” and “less irritating.” Greater preference may improve patient adherence and thereby improve symptom management of the patient's allergic rhinitis.

    A re-examination of former concepts is required to meet today’s medical challenges in allergic rhinitis. Previously, neutrophils have been treated as a relatively homogenous cell population found in the nose both when the patient is suffering at the height of the allergic season as well as when the patient report no symptoms. However, new data indicates that neutrophils can be divided into different subsets with diverse roles in inflammation. We showed increased levels of neutrophils in peripheral blood, nasal biopsies and nasal lavage fluid (NAL) from allergic patients during the pollen season compared to healthy controls. A closer examination revealed that the activated subset of neutrophils, CD16high CD62Ldim, outweighed the normal form CD16high CD62Lhigh in nasal tissue among these patients. This skewed distribution was not seen in controls. The normal subset prevailed in peripheral blood from patients as well as controls, whereas CD16high CD62Ldim and CD16dim CD62Ldim subsets, the latter considered “end state” neutrophils before apoptosis, were elevated in NAL. Functional in vitro experiments revealed that activated neutrophils exhibit a T cell priming capacity and an ability to enhance eosinophil migration. Activated neutrophils may thus contribute to allergic inflammation seen in allergic rhinitis by priming T cells and attracting eosinophils. PMID:28272395

    Allergic rhinitis (AR) has been a significant healthcare burden on individuals and society. However, the detailed effect of different patterns of allergen exposure on the development of AR remains controversial. A mouse model of AR was established to address the complex relationships between allergen exposure and the development of AR. Allergic symptom, OVA-specific IgE in serum and nasal lavage fluid, allergic inflammation in nasal tissues were evaluated after intranasal sensitization and challenge of ovalbumin (OVA) in mice treated with two different doses of allergen for different sensitized durations. Exposure to different doses and sensitized durations of OVA were capable of inducing allergic nasal response. Repetitive OVA exposure in the sensitization phase induced the recruitment of eosinophils and goblet cell hyperplasia. The level of OVA-specific IgE in serum depended on OVA exposure and was mediated in a duration-related manner. In addition, mice treated with low-dose OVA for prolonged duration manifested the major features of human local allergic rhinitis. There were dose- and duration-related effects of allergen exposure on the development of AR. LAR was associated with repetitive exposure to low-dose allergen. Thus, allergen avoidance should be an important aim of AR management.

    Allergic rhinitis is classically defined as an IgE-mediated inflammation of nasal mucosa, characterised by nasal obstruction, rhinorrhea, sneezing and nasal itching. It is certainly a high-prevalence disease and an important social and medical problem in many industrialised Countries, affecting about 20% of the general population; moreover, it is diagnosed with increasing frequency, both in adults and children in many developing countries. In view of the high medical and social costs, a correct diagnostic approach to allergic rhinitis is a fundamental need for the otorhinolaryngologist, also considering the severe complications (asthma, rhinosinusitis, rhino-otitis, rhinosinusal polyposis) which could develop if this disease is not recognised and adequately treated in its early phases. In order to evaluate not only the present epidemiological characteristics of allergic rhinitis in Italy but also the most commonly used diagnostic and therapeutic approaches in the management of this disease, 145 Italian otorhinolaringologists were selected to take part in the investigation. Each was invited to complete a questionnaire, divided into 8 different sections, to be answered according to their daily clinical practice. The significance of the results has been compared with those of the international samples comprised in the ARIA Document and in the epidemiologic survey of the Standing Committee on Rhinology and Allergy of the International Federation of Otorhinolaryngological Societies. A critical analysis of these data leads to some interesting epidemiological and therapeutic considerations.

    The effects of Sho-seiryu-to, an antiallergic Kampo medicine, on experimental allergic rhinitis were investigated in actively sensitized guinea pigs. The number of sneezes and scratches by the animals after a topical antigen challenge was significantly inhibited by pretreatment with Sho-seiryu-to (1000 mg/kg per os p.o.). The antigen-induced eosinophil infiltration in the nasal mucosa was significantly inhibited by Sho-seiryu-to (1000 mg/kg p.o.). Sho-seiryu-to (100 mg/kg p.o.) also reduced the increase in dye leakage to the nasal cavity induced by the antigen challenge and the antigen-induced decrease in volume of the nasal cavity was inhibited. Moreover, Sho-seiryu-to (1000 mg/kg p.o.) suppressed the volume change in the nasal cavity induced by leukotriene D4. These results demonstrate that Sho-seiryu-to inhibits experimental allergic rhinitis in guinea pigs, confirming that the agent may be beneficial for the treatment of allergic rhinitis.

    Given the impact of allergic rhinitis (AR) on quality of life, it is important that AR medications have rapid onset of symptom relief. The objective of this study was to determine the onset of action of loratadine (CAS 79794-75-5)/montelukast (CAS 151767-02-1) 10 mg/10 mg (L/M) versus placebo in seasonal AR (SAR) subjects. In this single-center, double-blind, crossover study, subjects with SAR and confirmed sensitivity to grass pollen received single doses of L/M or placebo following exposure to grass pollen in the Vienna Challenge Chamber. Subjects recorded symptoms at 15-min intervals during the first 2 h post dose and at 30-min intervals during the next 2 h. After a 14-day washout, the subjects crossed over to the other treatment. The primary endpoint was onset of action of L/M, defined as the first time point at which the mean change from baseline in total symptom score became and remained significantly different with L/M versus placebo. Secondary endpoints included nasal congestion score and rhinomanometry findings. Onset of action with L/M for total symptom score was 1 h, 45 min (P < 0.01 vs placebo). Significant improvements in subject-assessed nasal congestion scores (P < 0.01) and rhinomanometry (P = 0.036) were noted with L/M as compared with placebo. Overall, L/M was well tolerated. In conclusion, L/M demonstrated rapid onset for broad symptom relief, including nasal congestion, in subjects with SAR.

    The molecular allergy technique, currently defined as component-resolved diagnosis, significantly improved the diagnosis of allergy, allowing for differentiation between molecules actually responsible for clinical symptoms (genuine sensitizers) and those simply cross-reacting or shared by several sources (panallergens), thus influencing the appropriate management of a patient's allergy. This also concerns allergen immunotherapy (AIT), which may be prescribed more precisely based on the component-resolved diagnosis results. However, the advance in diagnosis needs to be mirrored in AIT. According to consensus documents and to expectations of specialists, therapy should be based on standardized extracts containing measured amounts of the clinically relevant molecules, ie, the major allergens. The new generation of extracts for sublingual immunotherapy fulfills these requirements and are thus defined as biomolecular (BM). BM refers to natural extracts with a defined content of major allergens in micrograms. All Staloral BM products are indicated for the treatment of allergic rhinitis with or without asthma. The effectiveness of AIT is related to its ability to modify the immunological response of allergic subjects. The 5-grass and house dust mite extracts were evaluated addressing the T helper 1, T helper 2, and T helper 3 cells by polymerase chain reaction array on mRNA extracted from Waldeyer's ring tissue (adenoids). Sublingual immunotherapy with a defined content of major allergens in micrograms induced a strong downregulation of genes involved in T helper 2 and T helper 1 activation and function, allowing the definition of the immunologic effect as "bio-homeostatic". This clinical and immunological model must be implemented with respect to other allergens, thus expanding the application of a treatment with a unique disease-modifying capacity.

    The occurrence of allergic rhinitis (AR) may be significantly influenced by air pollution. This study examined the association between the first occurrence of AR in preschool children and the pre-incident levels of air pollutants in Taiwan. We identified 9960 eligible subjects from a systematic sampling cohort database containing 400,000 insureds of the National Health Insurance from 2007 to 2011 and matched them with the environmental monitoring data from 2006 to 2011 according to the locations of their clinics. Pre-incident levels were determined using the average concentrations of air pollutants one or two weeks prior to the AR diagnoses. Logistic regression analyses were performed to determine any significant relationships between AR and specific air pollutants. The first AR incidence for Taiwanese preschool children, which increased with age, was 10.9% on average; boys appeared to have a higher percentage (14.2%) than girls (8.27%). Among the air pollutants, carbon monoxide (CO) and nitrogen oxides (NOX) were significantly related to AR after adjusting for age and gender (p < 0.05). Because both pollutants are considered to be traffic emissions, this study suggests that traffic emissions in Taiwan need to be controlled to lower the prevalence of children's AR.

    Background: The development of allergic rhinitis (AR) is caused by the interaction between genetic predisposition and environmental factors. In this study, the association between GATA3 single nucleotide polymorphisms and AR in an Iranian population was identified. Methods: This case-control study was performed on 86 patients with AR and 86 healthy subjects. This study aimed to evaluate a potential association between two GATA3 SNPs, rs1269486 and rs2229360, and AR. Blood samples were collected and DNA was extracted for the evaluation of these SNPs by RFLP-PCR. Results: A statistically-significant association was found between rs1269486 and AR (P<0.001). The frequencies of the A and GA genotypes were less in patients than in controls. The frequencies of the G allele and the GG genotype were greater in patients than in controls (P < 0.001). Conclusions: SNP rs1269486 of GATA3 was associated with AR and sensitivity to aeroallergens in our population. Because of the significance of this gene in AR, studying the association between GATA3 polymorphisms and AR is recommended for other populations. PMID:28367470

    Background Heredity as well as external factors influences the development of allergic rhinitis. The aim of this study was to analyse early risk factors and protective factors for allergic rhinitis at school age. Methods This is a prospective, longitudinal study of children born in western Sweden in 2003 where 50% of the birth cohort was randomly selected. The parents answered questionnaires at 6 months, 12 months, 4.5 yr and 8 yr. At 8 yr, 5044 questionnaires were distributed. Of these, 4051 responded, that is, 80.3%. Current allergic rhinitis was defined as symptoms and use of medication during the past 12 months. Results Current allergic rhinitis at 8 yr was reported by 10.9%. Mean onset age was 5.7 yr, and 61.9% were boys. In a multivariate analysis, antibiotics in the first week of life increased the risk of allergic rhinitis (adjusted odds ratio 1.75, 95% confidence interval (1.03, 2.97)). Increased risk was also seen with parental allergic rhinitis (aOR 2.73 (2.12, 3.52)), food allergy first year (aOR 2.45 (1.61, 3.73)), eczema first year (aOR 1.97 (1.50, 2.59)) and male gender (aOR 1.35 (1.05, 1.74)). Living on a farm at 4.5 yr reduced the risk (aOR 0.31 (0.13, 0.78)). Conclusion Antibiotics in the first week of life increased the risk of allergic rhinitis at school age, while living on a farm at preschool age reduced the risk. Both findings are compatible with the hygiene hypothesis. PMID:24912441

    Allergic rhinitis is associated with elevated serum IgE levels. IgE response is mediated by the high-affinity IgE receptor (FcεRI), which is polymorphic. Studies analyzing the association between allergic rhinitis and FcεRI variants have been conducted with controversial results. The objective of this study is to analyze, in 1,041 individuals, the putative clinical association of allergic rhinitis with common polymorphisms in FcεRI subunits genes. These SNPs included FECR1A rs2494262, rs2427837 and rs2251746; FECR1B rs1441586, rs569108 and rs512555; FCER1G rs11587213, rs2070901 and rs11421. Statistically significant differences were observed for the FCER1B rs569108 and rs512555 polymorphisms frequencies when comparing patients with allergic rhinitis without asthma and controls. The OR (95% CI) value for the 237Gly allele (rs569108) is equal to 0.26 (0.08-0.86, P = 0.017) and for the G allele (rs512555) it is equal to 0.27 (0.08-0.88, P = 0.020). These two SNPs are linked (D' = 1.0, LOD = 56.05). Also observed was a statistically significant trend towards lower IgE values among allergic rhinitis patients with variant alleles for both SNPs. In conclusion, in patients with allergic rhinitis without asthma, the FCER1B rs569108 and rs512555 polymorphisms are associated with increased risk of developing allergic rhinitis and with lower IgE levels.

    Transient receptor potential vanilloid 1 (TRPV1), which has been identified as a molecular target for the activation of sensory neurons by various painful stimuli, was reported to regulate the signaling and activation of CD4+ T cells. However, the role of TRPV1 in CD4+ T cell in allergic rhinitis remains poorly understood. In this study, TRPV1 expression was localized in CD4+ T cells. Both knockout and chemical inhibition of TRPV1 suppressed Th2/Th17 cytokine production in CD4 T cells and Jurkat T cells, respectively, and can suppress T cell receptor signaling pathways including NF-κB, MAP kinase, and NFAT. In TRPV1 knockout allergic rhinitis (AR) mice, eosinophil infiltration, Th2/Th17 cytokines in the nasal mucosa, and total and ova-specific IgE levels in serum decreased, compared with wild-type AR mice. The TRPV1 antagonists, BCTC or theobromine, showed similar inhibitory immunologic effects on AR mice models. In addition, the number of TRPV1+/CD4+ inflammatory cells increased in the nasal mucosa of patients with AR, compared with that of control subjects. Thus, TRPV1 activation on CD4+ T cells is involved in T cell receptor signaling, and it could be a novel therapeutic target in AR. PMID:26700618

    Objective Probiotics have proven beneficial in a number of immune-mediated and allergic diseases. Several human studies have evaluated the efficacy of probiotics in allergic rhinitis, however, evidence for their use has yet to be firmly established. The current systematic review seeks to synthesize the results of available randomized trials. Study Design Systematic review and meta-analysis. Methods The Medline, EMBASE, and Cochrane Library databases were reviewed and randomized controlled trials were extracted based on defined inclusion criteria. The effect of probiotics on Rhinitis Quality of Life (RQLQ) scores, Rhinitis Total Symptom Scores (RTSS), as well as total and antigen-specific serum IgE levels were evaluated by meta-analysis. Results A total of 23 studies with 1919 patients were identified, including 21 double-blind randomized controlled trials and 2 randomized crossover studies. Multiple probiotic strains, study populations, and outcome measures were utilized in individual trials. Seventeen studies showed a significant clinical benefit from the use of probiotics in at least one outcome measure when compared to placebo, while 6 trials showed no benefit. Among the trials eligible for meta-analysis, the use of probiotics resulted in significant improvement in RQLQ scores compared to placebo [standard mean difference (SMD) −2.23; p = 0.02]. Probiotics had no effect on RTSS [SMD −0.36; p = 0.13] or total IgE levels [SMD 0.01; p = 0.94], while there was a trend toward a reduction in antigen-specific IgE [SMD 0.20; p = 0.06] in the placebo group compared to probiotic. Conclusions Probiotics may be beneficial in improving symptoms and quality of life in patients with allergic rhinitis, however, current evidence remains limited due to study heterogeneity and variable outcome measures. Additional high-quality studies are needed to establish appropriate recommendations. PMID:25899251

    Objectives Silver has long been known as a strong antimicrobial and disinfectant. Several types of nano-silver coated products have been developed. However, the antimicrobial and disinfectant characteristics of nano-silver have not been well studied. The aim of this study was to investigate the effect of nano-silver on allergic inflammation in a mouse model. Methods Female BALB/C mice were sensitized by intraperitoneal injection of ovalbumin (OVA) and aluminium hydroxide on days 0, 7, 14, and 21. Mice were challenged with intranasal instillation of OVA. Nano-silver was also administered nasally prior to intranasal instillation of OVA. Severity of allergic rhinitis was assessed according to nasal symptoms, serum OVA-specific IgE level, interleukin (IL)-4, IL-10, and interferon (INF)-γ levels in nasal lavage fluid. Hematoxylin-eosin stain and periodic acid-Schiff stain were performed for evaluation of histological change. Results Nano-silver attenuated manifestation of nasal symptoms in sensitized mice and inhibited production of OVA-specific IgE, IL-4, and IL-10, however, it had no effect on INF-γ level. In addition, the degree of inflammatory cell infiltration and goblet cell hyperplasia was attenuated by nano-silver. Conclusion These results suggest that nano-silver may effectively reduce allergic inflammation in a mouse model of allergic rhinitis. Through its properties as an anti-inflammatory agent, nano-silver may be a useful therapeutic strategy. PMID:23205228

    Bu-zhong-yi-qi-tang, an ancient formula of Chinese medicine usually used in the treatment of allergic diseases, was evaluated in the treatment of patients with perennial allergic rhinitis. In this study, 60 patients allergic to house dust mite allergen confirmed by skin test and MAST test were recruited and randomized. An experimental group of 36 patients was treated with Bu-zhong-yi-qi-tang, whereas a control group of 24 patients was treated with a non-effective formula Ping-wei-san for 3 months. The nasal symptomatic scores and the responses of polymorphonuclear neutrophils (PMN) to IL-4-stimulation were measured after treatment. The nasal symptomatic scores in the experimental group were significantly improved (3.78+/-0.09 before treatment vs. 0.57+/-0.06 after treatment). In contrast, no change was found in symptomatic scores in the control group (3.17+/-0.12 before treatment vs. 2.79+/-0.14 after treatment). Moreover, total serum IgE and the IL-4-stimulated production of PGE(2) and LTC(4) by PMN was significantly suppressed in the experimental group after treatment compared to the control group. The COX-2 mRNA expression in IL-4-stimulated PMN was also significantly suppressed after Bu-zhong-yi-qi-tang treatment. These results suggest that Bu-zhong-yi-qi-tang but not Ping-wei-san was beneficial to the patients with perennial allergic rhinitis via suppressed nasal inflammation by an antiinflammatory effect.

    Indoor air quality has become increasingly important as we live in a society where the majority of our time is spent indoors. Specific attention has been drawn to airborne fungal spores as a factor affecting indoor air quality. This study targeted shortcomings of other studies by utilizing long-term air sampling and total fungal spore enumeration to determine associations between health outcomes and fungal spore concentrations. Infants (n = 144) were clinically evaluated and had skin prick tests (SPT) for 17 allergens. Airborne fungal spores were collected using a Button Personal Inhalable Sampler (SKC Inc.) for 48 h at a flow rate of 4 l/min. Sampling was conducted in the spring (March-May) or fall (August-October) in 2003-2004. Fungal spores were analyzed using microscopy-based total counting and identified to the genus/group level. Total spore and individual genus concentrations were analyzed for associations with rhinitis and positive SPT results. Overall, concentrations varied widely, between <2 and 2294 spores/m(3). While no relationship was observed between SPT(+) and total fungal counts, several significant associations were found when analysis was conducted on the various fungal genera and health outcomes. Positive associations were obtained between: Basidiospores and rhinitis (p < 0.01), Penicillium/Aspergillus and SPT(+) to any allergen (p < 0.01), and Alternaria and SPT(+) to any allergen (p < 0.01). Inverse associations were found between: Cladosporium and SPT(+) to any allergen (p < 0.05), and Cladosporium and SPT(+) to aeroallergens (p < 0.05). This study indicates that health outcome may vary by fungal genera; some fungal types may have sensitizing effects while others may have a beneficial role.

    Background The supplement Pycnogenol® (PYC) has been used for the treatment of several chronic diseases including allergic rhinitis (AR). However, the in vivo effects on allergic inflammation have not been identified to date. Aims To investigate the treatment results of PYC on allergic inflammation in a rat model of allergic rhinitis. Study Design Animal experimentation. Methods Allergic rhinitis was stimulated in 42 rats by intraperitoneal sensitization and intranasal challenge with Ovalbumin. The animals were divided into six subgroups: healthy controls, AR group, AR group treated with corticosteroid (dexamethasone 1 mg/kg; CS+AR), healthy rats group that were given only PYC of 10 mg/kg (PYC10), AR group treated with PYC of 3mg/kg (PYC3+AR), and AR group treated with PYC of 10 mg/kg (PYC10+AR). Interferon-γ (IFN-γ), interleukin-4 (IL-4), interleukin-10 (IL-10), and OVA-specific immunoglobulin E (Ig-E) levels of serum were measured. Histopathological changes in nasal mucosa and expression of tumor necrosis factor-α (TNF-α) and IL-1β were evaluated. Results The levels of the IL-4 were significantly decreased in the PYC3+AR, PYC10+AR and CS+AR groups compared with the AR group (p=0.002, p<0.001, p=0.006). The production of the IFN-γ was significantly decreased in the PYC3+AR and PYC10+AR groups compared with the AR group (p=0.013, p=0.001). The administration of PYC to allergic rats suppressed the elevated IL-10 production, especially in the PYC3+AR group (p=0.006). Mucosal edema was significantly decreased respectively after treatment at dose 3 mg/kg and 10 mg/kg PYC (both, p<0.001). The mucosal expression of TNF-α has significantly decreased in the PYC3+AR and PYC10+AR groups (p=0.005, p<0.001), while the IL-1β expression significantly decreased in the CS+AR, PYC3+AR, and PYC10+AR groups (p<0.001, p=0.003, p=0.001). Conclusion PYC has multiple suppressive effects on allergic response. Thus, PYC may be used as a supplementary agent in allergic response

    Cetirizine (Zyrtec) is a potent and long-acting second-generation histamine H1- receptor antagonist for the treatment of allergic disease, such as allergic rhinitis and chronic idiopathic urticaria, in adult and child. It is a racemic mixture of levocetirizine (Xyzal) and dextrocetirizine. The purpose of this present study was to compare the efficacy of cetirizine, levocetirizine and placebo for the treatment of pediatric perennial allergic rhinitis. 74 perennial allergic rhinitis patients, aged 6 to 12 years old, assigned to 1 of 3 treatment groups for 12 weeks randomly. The effects of the three agents were compared with the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) and Total Symptom Score (TSS) by diary. Nasal peak expiratory flow rate (nPEFR) and laboratory examinations including serum immunoglobulin E level, eosinophil cationic protein (ECP), blood eosinophil counts and eosinophil percentage in a nasal smear were evaluated among the three groups. The results revealed that both cetirizine and levocetirizine improved TSS in comparison with the placebo group, and ceterizine appeared to be more efficacious than levocetirizine at week 8 and week 12. The PRQLQ score showed significant decreased both in cetirizine and levocetirizine group, but there was no statistic significant difference between both groups. The eosinophil proportion in a nasal smear significantly decreased among the cetirizine in comparison with the placebo group but there was no statistic significant in levocetirizine groups. Both cetirizine and levocetirizine showed significant improvement in nPEFR in comparison with the placebo group, and ceterizine appeared to be more efficacious than levocetirizine. The 12-week treatment program showed that cetirizine was more effectious than levocetirizine.

    In recent times, the incidence of allergic diseases, particularly bronchial asthma, has been increasing worldwide. However, there appears to be no published data on the prevalence of allergic diseases among school children (3 to 16 years of age) in Karachi, Pakistan, with only limited data available among few age groups under one ISAAC study. The objective of this project was to investigate the prevalence of allergic diseases among school children (3 to 16 years of age) in the city of Karachi. The questionnaire that was used for data collection had previously been used for a similar study in neighboring Saudi Arabia and the U.A.E. In 2007, a total of 3,000 surveys were distributed in various schools of Karachi, of which 2,325 completed surveys were obtained. SPSS was used to perform statistical analysis on the collected data. Survey results showed that the frequency of diagnosed (previously seen by physicians) cases of asthma stood at 15.8%, while the frequency of allergic rhinitis was found to be 28.50% among these children. Other parameters that were analyzed included dry cough (20.1%), wheezing (11.7%), breathlessness (15.40%), and eczema (21.8%). Furthermore, smoking by family members was found to be associated with asthma (p value less than 0.05), allergic rhinitis (p value less than 0.05), breathlessness (p value less than 0.05), dry cough (p value 0.002), and wheezing (p value less than 0.05). This study reveals that there is a significant number of school children in the metropolitan city of Karachi who have various allergic symptoms. It also sheds light on the fact that exposure to indoor environmental factors as well as family atopy can play a key role in increasing the chances of an individual to experience asthma and other allergy symptoms.

    Intranasal corticosteroids are well known to be efficacious in the treatment of allergic rhinitis. Nasal irrigation with saline, including hypertonic saline, has long been recommended for the treatment of sinonasal disease, and it has been shown to have a positive effect on the physiology of the nasal mucosa. Until now, no study of the clinical efficacy of intranasal hypertonic Dead Sea saline as a monotherapy for seasonal allergic rhinitis has been reported. We conducted a prospective, randomized, single-blind, placebo-controlled comparison of intranasal hypertonic Dead Sea saline spray and intranasal aqueous triamcinolone spray in 15 patients with seasonal allergic rhinitis. Results were based on a 7-day regimen. Based on Rhinoconjunctivitis Quality of Life Questionnaire scores, clinically and statistically significant (p < 0.0001) improvements were seen in both active-treatment groups; as expected, the corticosteroid spray was the more effective of the two treatments. No significant improvement occurred in the control group. Our preliminary results not only confirm the efficacy of intranasal corticosteroid therapy in moderate-to-severe allergic rhinitis, they also suggest that the Dead Sea saline solution can be an effective alternative in mild-to-moderate allergic rhinitis, particularly with respect to nasal and eye symptoms. The hypertonicity of the Dead Sea solution may have a positive effect on the physiology of the nasal mucosa by improving mucociliary clearance. In addition, the dominant cation in the Dead Sea solution--magnesium--probably exerts anti-inflammatory effects on the nasal mucosa and on the systemic immune response.

    Chlorophyll c2 extracted from Sargassum horneri improved allergic symptoms in an animal model of allergic rhinitis. In the present study, we explored the efficacy of chlorophyll c2 in patients with seasonal allergic rhinitis. This was a single-center, randomized, double-blind placebo-controlled trial. Sixty-six patients aged 20-43 years, each with a 2-year history of seasonal allergic rhinitis, were randomly assigned to receive either a single daily dose (0.7 mg) of chlorophyll c2 or placebo for 12 weeks. The use of medications including H1-antihistamines and topical nasal steroids was recorded by rescue medication scores (RMSs) noted after 4, 8, and 12 weeks of treatment. Disease-specific quality of life was measured using the Japan Rhinitis Quality of Life Questionnaire (JRQLQ) both before and after 4, 8, and 12 weeks of treatment. The RMS at 8 weeks was significantly better in the chlorophyll c2 than the placebo group (mean RMS difference = -3.09; 95 % confidence interval = -5.96 to -0.22); the mean RMS at 4 weeks was only slightly better in the chlorophyll c2 group. The JRQLQ scores did not differ significantly between the two groups. Chlorophyll c2 would have a potential to be an alternative treatment for allergic rhinitis.

    Rhinitis is a common problem in primary care which is often managed sub-optimally. It causes considerable morbidity and has been shown to have a detrimental impact on people's ability to concentrate at school and at work. Rhinitis and asthma often present together, and symptomatic rhinitis can be associated with poor asthma control and increased risk of exacerbations. There is therefore a clear need to recognise and treat rhinitis according to guideline recommendations. This article is a primary care summary of the British Society for Allergy & Clinical Immunology (BSACI) Standards of Care Committee guideline on the management of rhinitis, written by a multi-disciplinary group of clinicians. It takes into account the time restrictions on assessment and the tests and equipment available in primary care, as well as the need for practical, clear and intuitive strategies for investigation and management. It recommends a stepwise approach to treatment, and highlights the relevance of less frequently prescribed treatments, including nasal douching leukotriene receptor antagonists and anticholinergics. Red flag symptoms are identified, together with indicators for referral. As with many other long term conditions, good communication between primary and secondary care in terms of timely and appropriate referral is a key factor for success.

    Asthma and allergic rhinitis often coexist and are increasing worldwide, particularly among the younger generation. Although the prevalences of adult asthma and allergic rhinitis and their risk factors have been reported, there have been few studies focusing on young adults. The aim of this study was to evaluate the prevalences of asthma and allergic rhinitis and their associated factors in Japanese young adults. A questionnaire survey of new students at Hokkaido University about the presence of current wheeze and rhinitis and a history of several viral infections during childhood was conducted in 2008 and 2010. The prevalences of wheeze and rhinitis and their associated factors were evaluated. Of 4076 nonsmoking subjects aged 18-25 years, 261 (6.4%) had current wheeze and 1373 (33.7%) had allergic rhinitis. On multivariate analyses, current wheeze was associated with high body mass index (BMI), atopic dermatitis, allergic rhinitis, food allergy, and a history of measles infection. In contrast, allergic rhinitis was associated with low BMI, current wheeze, atopic dermatitis, food allergy, and no history of measles. When subjects were classified into four groups by the presence or absence of wheeze and rhinitis, both high BMI and a history of measles were positively associated with wheeze without rhinitis but negatively associated with rhinitis without wheeze. High BMI and past measles infection showed contrasting associations with asthma and allergic rhinitis in nonsmoking young adults. It is important to not only recognize the common pathophysiological characteristics of asthma and allergic rhinitis but also to understand their differences.

    Abstract: The prevalence of allergic diseases such as allergic rhinitis (AR) and asthma are markedly increasing to epidemic proportions worldwide as societies adopt Western lifestyles. An estimated 300 million persons worldwide have asthma, about 50% of whom live in developing countries, and about 400 million people suffer from AR. AR has a marked impact on quality of life, socially, at school, and in the workplace and is a huge socioeconomic burden. Thus, there was clearly a need for a global evidence-based guideline not only for managing AR but also highlighting the interactions between the upper and lower airways including diagnosis, epidemiology, common risk factors, management, and prevention. The Allergic Rhinitis and its Impact on Asthma (ARIA) document was first published in 2001 as a state-of-the-art document for the specialist, the general practitioner, and other health care professionals. Subsequent research and increasing knowledge have resulted in the ARIA 2008 update. The present review summarizes the ARIA update with particular emphasis on the current status of AR and asthma in Asia Pacific. PMID:23268481

    Chronic rhinitis (CR) is a common disorder in children. Allergic rhinitis (AR) is a risk factor for CR, and children with AR tend to suffer more from hypertrophic adenoids than do patients with nonallergic rhinitis (NAR). Few studies have addressed the issue of alleviating symptoms of pediatric CR or AR following adenoidectomy alone. We conducted a retrospective chart review to determine whether CR in children improves after adenoidectomy and whether children with AR will benefit more than those with NAR. Charts of 47 children who had undergone adenoidectomy for nasal obstruction and chronic middle ear effusion were reviewed. AR and NAR subgroups were classified based on symptoms, signs, blood IgE, and nasal smear (allergic criteria). Hypertrophic adenoids were graded using the adenoid-to-nasopharyngeal ratio (ANr >0.8). A questionnaire was used to assess the change in chronic rhinitis postoperatively. Improvement in CR was reported in 37 of 47 (79%) children. Patients with AR improved to a higher extent than those with NAR (12 of 14 [86%] vs. 25 of 33 [76%], respectively), but the difference was not statistically significant. A total of 41 lateral postoperative nasopharyngeal x-rays were obtained. The x-rays revealed that 20 of 26 (77%) of patients with ANr >0.8 had complete and 4 of 26 (15%) had partial resolution of symptoms of CR for a total resolution rate of 92%, compared to only a 53% resolution in the ANr <0.8 subgroup (6 of 15 and 2 of 15 patients, respectively [p <0.05]). The correlation between adenoid size and resolution of CR was not related to any of the AR/NAR subgroups. We conclude that symptoms of CR may improve after adenoidectomy in children who are experiencing nasal obstruction and chronic otitis media with effusion. Clinical improvement did not differ between AR and NAR patients, and was more prominent in children with hypertrophic adenoids (ANr >0.8).

    Local nasal immunotherapy (LNIT) has been reported to be effective for mite-induced allergic rhinitis. However, its compliance is poor due to persistent nasal reactions and difficult application. The main objective of this study was to develop a Dermatophagoides pteronyssinus (Der p)-coated strip for self-application and to evaluate its clinical efficacy. Randomized, double-blind, placebo-controlled trials were carried out to evaluate the efficacy and compliance of LNIT. A total of 35 patients with allergic rhinitis from the allergy clinic were recruited to receive four months of LNIT. Clinical efficacy was evaluated by the symptoms of sneezing, rhinorrhea and nasal stuffiness. Local and systemic effects were evaluated by measuring histamine and eosinophil cationic protein (ECP) in nasal discharge and allergen-specific IgG1, IgG4 and IgE in sera. LNIT with Der p-coated strips could reduce nasal symptoms and modulate the serum levels of Der p-specific IgG1, IgG4 and IgE. The secretion of both histamine and ECP was reduced within four months after treatment. When the symptomatic and immunological changes were compared between active treatment and placebo groups, the improvements were greater in the active treatment groups for all three symptom scores. There were no severe adverse events except nasal response persisting within the first month in some cases. LNIT with a steady dose of Der p-coated strips can be self-administered at home without any systemic reactions. Both local and systemic immune responses were observed after LNIT. This therapeutic modality may serve as a good alternative treatment for allergic rhinitis.

    Objective: Allergic rhinitis is a common, usually long-standing, condition that may be self-diagnosed or have a formal diagnosis. Our aim was to identify how allergic rhinitis sufferers self-manage their condition. Methods: A sample of 276 self-identified adult allergy sufferers pooled from social media completed an online survey comprising 13 questions. The survey was fielded by a professional research organization (Lab42). The main outcome measures included the use of prescription and/or non-prescription allergy medication, and interactions with physician and/or pharmacist with respect to medication use. Results: Of the respondents, 53% (146/276) indicated that they used both prescription and over-the-counter medication to manage their allergy symptoms. Of those who used prescription medication, 53% reported that they discussed their prescription medication in great detail with their physician when it was prescribed, while 42% spoke about it briefly. Following the initial prescription, few discussions about the prescription occur with the physician (45% indicate several discussions, 40% indicate one or two discussions, and 10% indicate no discussions). In most cases (~75% of the time), allergy prescription refills did not require a doctor visit with patients obtaining refills through phone calls to the doctor’s office or through the pharmacy. Two-thirds of patients (69%) report that they have discussed their prescription allergy medication with a pharmacist, with greater than half of respondents having discussed the use of the non-prescription medication with their doctor. Conclusion: Patients with diagnosed allergic rhinitis appear to be self-managing their condition with few interactions with their doctor about their allergy prescription. Interactions with a pharmacist about allergy medication (prescription and non-prescription) appear to be more common than interactions with a physician. PMID:26770793

    With the continuous rapid urbanization process over the last three decades, outdoors air pollution has become a progressively more serious public health hazard in China. To investigate the possible associations, lag effects and seasonal differences of urban air quality on respiratory health (allergic rhinitis) in Changchun, a city in Northeastern China, we carried out a time-series analysis of the incidents of allergic rhinitis (AR) from 2013 to 2015. Environmental monitoring showed that PM2.5 and PM10 were the major air pollutants in Changchun, followed by SO₂, NO₂ and O₃. The results also demonstrated that the daily concentrations of air pollutants had obvious seasonal differences. PM10 had higher daily mean concentrations in spring (May, dust storms), autumn (October, straw burning) and winter (November to April, coal burning). The mean daily number of outpatient AR visits in the warm season was higher than in the cold season. The prevalence of allergic rhinitis was significantly associated with PM2.5, PM10, SO₂ and NO₂, and the increased mobility was 10.2% (95% CI, 5.5%-15.1%), 4.9% (95% CI, 0.8%-9.2%), 8.5% (95% CI, -1.8%-19.8%) and 11.1% (95% CI, 5.8%-16.5%) for exposure to each 1-Standard Deviation (1-SD) increase of pollutant, respectively. Weakly or no significant associations were observed for CO and O₃. As for lag effects, the highest Relative Risks (RRs) of AR from SO₂, NO₂, PM10 and PM2.5 were on the same day, and the highest RR from CO was on day 4 (L4). The results also indicated that the concentration of air pollutants might contribute to the development of AR. To summarize, this study provides further evidence of the significant association between ambient particulate pollutants (PM2.5 and PM10, which are usually present in high concentrations) and the prevalence of respiratory effects (allergic rhinitis) in the city of Changchun, located in Northeastern China. Environmental control and public health strategies should be enforced to

    Allergic rhinitis affects a large number of children and exerts a considerable socioeconomic impact. It is underdiagnosed and inadequately treated, which predisposes children to potentially serious comorbidities. Allergic rhinitis symptoms may create nighttime breathing problems and sleep disturbances and have a negative effect on a child's ability to learn in the classroom. Although antihistamines have shown efficacy in relieving many symptoms, they have little effect on nasal congestion. This article summarizes the advantages of intranasal corticosteroids, including their effectiveness against congestion and excellent safety profile. Intranasal corticosteroids with minimal systemic bioavailability provide topical drug delivery that minimizes the potential for systemic side-effects.

    The primary care physician is the first line of treatment for allergic rhinitis, which affects approximately one-fourth of children in the United States. There is an increasing trend toward self-management by patients or parents due to high-deductible insurance plans and the over-the-counter availability of allergy medications. The primary care physician can offer guidance on appropriate selection of medications and potential adverse effects. Vitamin D deficiency has been proposed as a potential contributing factor in patients with allergic diseases, and studies are underway to determine whether supplementation with vitamin D is helpful for these conditions. Sublingual immunotherapy has recently received US Food and Drug Administration approval for grass and ragweed allergens; many children will be interested in this alternative to allergy shots. The relative advantages and disadvantages of sublingual vs subcutaneous immunotherapy are discussed.

    The precise pathogenesis of allergic rhinitis (AR) remains unclear and AR is less easily cured. Recent evidence has suggested that calcium-activated K+ channel-3.1(KCa3.1) is implicated in the immune response of allergic and inflammatory diseases and TRAM-34 is a selective KCa3.1 blocker. However, little is known about its role in AR. We aimed to investigate the effect of TRAM-34 in a mouse model of AR induced by ovalbumin (OVA). The BALB/c mice were divided into six groups: untreated AR group, 200 μg TRAM-34 treated AR group, 400 μg TRAM-34 treated AR group, 200 μg TRAM-34 treated normal group, 400 μg TRAM-34 treated normal group and untreated normal control group. Histopathological characteristics were assessed by HE staining. KCa3.1 protein expression was investigated by immunohistochemistry and western blotting method, and mRNA expression of KCa3.1, stromal interaction molecule1 (STIM1) and Orai1 in nasal tissues were assessed by real-time PCR. Furthermore, concentrations of OVA-specific IgE, ECP, IL-4, IL-5, IL-17 and IL-1β in nasal lavage fluid (NLF) were analyzed by enzyme-linked immunosorbent assay (ELISA). Results showed that TRAM-34 administration into the nostril attenuated sneezing, nasal rubbing, epithelial cell proliferation, eosinophil infiltration and inhibited nasal mucosa KCa3.1, STIM1 and Orai1 expression in TRAM-34 treated mice compared with untreated AR mice and suppressed inflammatory cytokines in the NLF of TRAM-34 treated groups compared with untreated AR mice. In conclusion, TRAM-34 could effectively alleviate murine allergic rhinitis by suppressing KCa3.1 and leads to reduction of K+ efflux and Ca2 + influx, leading to inflammation reduction and allergic responses attenuation.

    Reactive oxygen species are products of cellular metabolism and assigned important roles in biomedical science as deleterious factors in pathologies. In fact, some studies have shown that the therapeutic benefits of taking antioxidants were limited and the potential for therapeutic intervention remains unclear. New evidences showed that ROS have some ability of intercellular transportation. For treating allergic rhinitis, as a novel intracellular superoxide quencher, TAT-SOD applied to acupoints LI 20 instead of directly to nasal cavity can be used to test that. TTA group apply TAT-SOD cream prepared by adding purified TAT-SOD to the vehicle cream to acupoints LI 20, while placebo group used the vehicle cream instead. TTN group applied the same TAT-SOD cream directly to nasal cavity three times daily. Symptom scores were recorded at baseline and days 8 and 15. For the overall efficacy rate, TTA group was 81.0%, while placebo group was 5.9% and TTN was 0%. Malondialdehyde levels decreased observably in TTA group, and superoxide dismutase, catalase, and glutathione peroxidase levels remained basically unaffected. Enzymatic scavenging of the intracellular superoxide at acupoints LI 20 proved to be effective in treating allergic rhinitis, while no improvement was observed with the placebo group and TTN group.

    Allergic rhinitis (AR) is prevalent in Nigeria, though little information exists on the allergen. We assessed the clinical features of AR patients in our environment based on the allergic rhinitis impact on asthma (ARIA) classification. Only patients with positive skin prick test (SPT) were recruited. Seventy-four patients participated in the study. AR and asthma comorbidity were observed in 13.5%. The proportion of “sneezers-runners” was higher than “blockers” with significantly more “sneezers-runners” having persistent AR (P = 0.007). No relationship was established between these predominant symptoms and the aeroallergens used in this study. Intermittent mild and moderate/severe AR were evident in 13.5% and 31.1%, while persistent mild and moderate/severe were seen in 20.3% and 35.1%, respectively. House dust mites allergen yielded the highest number of positive responses (22.6%) followed by tree pollen (16.8%). No relationship was observed between the allergens tested and AR severity. Majority of patients were oligosensitive (33.8%) and polysensitive (35.1%) and were not significantly associated with AR severity (P = 0.07). Most AR patients presenting for treatment in Abuja, Nigeria, had moderate-severe persistent AR and showed similar SPT sensitization pattern with countries having similar climatic conditions. Sensitization patterns were not related to ARIA classification or predominant AR symptoms. PMID:27247577

    The present study aimed to compare the efficacy and safety of subcutaneous immunotherapy with Dermatophagoides pteronyssinus standardized extract administered in conventional and cluster immunotherapy regiments for patients with persistent allergic rhinitis. A total of 60 patients with moderate to severe allergic rhinitis caused by dust mites were treated for 1 year with either conventional immunotherapy (n=30) or cluster immunotherapy (n=30). Nasal conjunctival symptoms and signs were assessed to evaluate the clinical efficacy of the two regimens, and the incidence of local and systemic adverse reactions were also evaluated. The findings demonstrated that the cluster regimen reduced the duration between the initial and maintenance dose by >60%, and resulted in a significant improvement, as compared with the conventional regimen, after 6 weeks of observation (P<0.05). However, the incidence of local and systemic adverse reactions in the cluster regimen during the dose accumulation phase and the dose maintenance phase was not significantly different, as compared with the conventional immunotherapy regimen. These results suggest that cluster immunotherapy is efficacious and safe to treat patients who are clinically sensitive to dust mites. PMID:28352357

    Shenqi is a traditional Chinese polyherbal medicine has been widely used for the treatment of allergic rhinitis (AR). The aim of this study was to investigate the anti-allergic rhinitis activity of Shenqi and explore its underlying molecular mechanism. Ovalbumin (OVA)-induced allergic rhinitis rat model was used to evaluate the anti-allergic rhinitis effect of Shenqi. The effect of Shenqi on IgE-mediated degranulation was measured using rat basophilic leukemia (RBL-2H3) cells. Primary spleen lymphocytes were isolated to investigate the anti-allergic mechanism of Shenqi by detecting the expression of transcription factors via Western blot and the level of cytokines (IL-4 and IFN-γ) via ELISA. In OVA-induced AR rat models, Shenqi relieved the allergic rhinitis symptoms, inhibited the histopathological changes of nasal mucosa, and reduced the levels of IL-4 and IgE. The results from the in vitro study certified that Shenqi inhibited mast cell degranulation. Furthermore, the results of GATA3, T-bet, p-STAT6, and SOCS1 expression and production of IFN-γ and IL-4 demonstrated that Shenqi balanced the ratio of Th1/Th2 (IFN-γ/IL-4) in OVA-stimulated spleen lymphocytes. In conclusion, these results suggest that Shenqi exhibits an obvious anti-allergic effect by suppressing the mast cell-mediated allergic response and by improving the imbalance of Th1/Th2 ratio in allergic rhinitis.

    Background The proinflammatory cytokine interleukin (IL)-17A is associated with eosinophil infiltration into the nasal mucosa in a mouse model of ovalbumin-induced allergic rhinitis. Chemotaxis of eosinophils is mediated primarily through C-C chemokine receptor type 3 (CCR3). However, the mechanism underlying the IL-17A-mediated enhancement of eosinophil recruitment via chemoattractants/chemokines remains unknown. Objectives In this study, we assessed the contribution of IL-17A to eosinophil-related inflammation via the CCL7/CCR3 pathway in experimental allergic rhinitis. Methods IL-17A knockout (KO) and wild-type (WT) BALB/c mice were injected intraperitoneally and challenged intranasally with OVA to induce allergic rhinitis. Various parameters of the allergic response were evaluated, and mRNA and protein levels of CCL7 and CCR3 in nasal tissue and serum were compared between the two groups. The chemotactic response to CCL7 with or without IL-17A in bone marrow-derived eosinophils (bmEos) from BALB/c mice was measured. Results In the allergic rhinitis model, IL-17A deficiency significantly decreased nasal symptoms, serum IgE levels, and eosinophil recruitment to the nasal mucosa. CCL7 and CCR3 mRNA and protein levels were decreased in the nasal mucosa of IL-17A KO mice compared with the WT mice. BmEos showed a significantly increased chemotactic response to -low concentration of CCL7 in the presence of IL-17A compared with its absence. Conclusion The suppression of nasal inflammation due of IL-17A deficiency in allergic rhinitis is partly responsible for the regulation of CCL7 secretion and eosinophil infiltration, which may be regulated via the CCL7/CCR3 pathway.

    Data on allergic conditions as risk or protective factors for cancer are controversial probably because most studies have used self-reported data on mixed groups of allergies in a case-control setting. We define cancer risks in medically diagnosed hay fever/allergic rhinitis patients in a nationwide cohort study. A total of 138,723 hay fever/allergic rhinitis patients were identified from three Swedish health care databases and standardized incidence ratios (SIRs) were calculated for subsequent cancers identified from the Swedish Cancer Registry. Overall cancer risk was not changed (SIR 1.03). For individual cancers, the highest SIR was observed for nasal cancer (SIR 2.63), followed by testicular (1.46) and endocrine tumors (1.42), and kidney (1.31), prostate (1.18) and breast (1.11) cancers. The results were consistent in the three sources of data and all SIRs were above unity, albeit mainly not statistically significant. The SIRs for nervous system tumors were above unity and of borderline significance. SIRs were decreased for esophageal (0.50), liver (0.62) and lung (0.78) cancers, and the three sources of data agreed in the direction of the effect. The increased risks for testicular, renal, prostate and endocrine cancers may be explained by immunological mechanisms. Excess risk for these cancer accounts for a significant population attributable fraction. Nervous system cancers showed a borderline increase and none of the histological types were significantly decreased, providing strong evidence against the published case-control studies, which have reported protective effects. The reasons for the reduced risks for esophageal, liver and lung cancer remain to be explained.

    Introduction. Molds are a very diverse group of allergens. Exposure and sensitization to fungal allergens can promote the development and worsening of allergic rhinitis (AR). Objective. The natural course of allergic rhinitis was compared between a group of patients with allergy to molds and patients with AR to other allergens as the control groups. Material and Methods. The study group consisted of 229 patients, with a mean age of 27.4 ± 6.5 yrs. The study group was compared to groups of AR patients with allergy to house dust mites or pollens or with multivalent allergy. Allergic sensitization was assessed using the skin prick test (SPT) with a panel of 15 allergens to molds and other common inhalant allergens. Specific IgEs against all tested allergens were measured. Nasal fractional exhaled nitric oxide (FeNO) level was assessed with a chemiluminescence analyzer (NIOX MINO) and compared between groups. Cluster analysis was performed for determine models of AR in whole population. Results. Patients with allergy to mold have had AR with a higher blockage of nose than in the patients with other allergies. Alternaria alternata (59% of examined), Cladosporium herbarum (40%), and Aspergillus fumigatus (36%) were the predominant allergens in the study group. Patients with allergy to mold were more often present in two clusters: there were patients with more frequent accompanying asthma and high level of FeNO. Conclusion. Patients with allergy to molds have a significantly greater predisposition for bronchial asthma and high concentration of FeNO. PMID:27340656

    Background Allergic rhinitis and rhinosinusitis, common and debilitating conditions, should be managed in accordance with guideline recommendations. Guideline adherence shows regional differences. As of now, there is little data from Asia and none from Malaysia on the current treatment practices and unmet needs in the management of these conditions. Objective The objective of this study was to assess the current practice in the management of allergic rhinitis and rhinosinusitis by conducting a survey among ear, nose and throat (ENT) specialists, pharmacists, and general practitioners (GPs) in Malaysia. Methods We conducted a survey study among ENT specialists, pharmacists, and GPs in Malaysia, who answered a multiple choice questionnaire focused on the current practice in the management of allergic rhinitis and rhinosinusitis in their respective field. More than 200 ENT specialists, 100 pharmacists, and 200 GPs participated in the survey. Results Antihistamines were the most preferred choice for the treatment of mild allergic rhinitis by ENT specialists (45%), pharmacists (78%), and GPs (51%), with the most preferable duration of <2 weeks. In moderate-to-severe allergic rhinitis, a combination of antihistamines and intranasal steroids was the most preferred treatment of choice in 90% of ENT specialists, 72% of pharmacists, and 69% of GPs. Efficacy of antihistamines was the main criteria of choice in 58%, 53%, and 38% of ENT specialists, pharmacists, and GPs, respectively. Notably, complaints of drowsiness associated with nonsedative antihistamines were the major unmet need identified in the survey. For chronic rhinosinusitis, a combination of antihistamines and intranasal steroids was the most preferred treatment. The majority of the respondents preferred a treatment duration of >3 months with antihistamines. Satisfaction with the recommendations in the current Allergic Rhinitis and its Impact on Asthma (ARIA) guideline was high; 66%, 58%, and 89% of the ENT

    Allergic rhinitis (AR) is an allergic inflammation of the nasal airways. The Korean herbal medicine, So-Cheong-Ryong-Tang (SCRT) has been typically used for the treatment of AR for hundreds of years. In the present study, we investigated whether SCRT suppresses the progression of AR in animal model. AR was induced by ovalbumin (OVA). Treatment with SCRT was assessed to study the effect of SCRT on AR in mice. Histological analysis, multiplex cytokine assay, blood analysis, cell viability assay, RT-PCR and Elisa assay were performed to verify inhibitory effect of SCRT on AR. SCRT reduced infiltration of inflammatory cells into nasal cavity. SCRT reduced infiltration of mast cells into nasal mucosa. SCRT reduced the levels of cytokines (IL-4 and LIF) in the serum. SCRT reduced the levels of leukocytes in the blood. SCRT decreased cell viability of HMC-1 cells and splenocyte. SCRT suppressed IL-4 level in HMC-1 cells and splenocyte cells in a dose-dependent manner. SCRT suppressed IL-6 level and TNF-α level in splenocyte. SCRT suppresses the progression of AR induced by OVA. SCRT might be a useful drug for the treatment of AR.

    Plasminogen activator inhibitor (PAI-1) has an essential role in tissue remodeling after inflammation. Recent literature revealed only one study evaluating PAI-1 4G/5G gene polymorphism in children with asthma and none in children with allergic rhinitis. We aimed to investigate distribution of PAI-1 4G/5G polymorphism in a group of Turkish children with asthma and allergic rhinitis and compare these findings with those obtained in normal peers. Patients with physician-diagnosed asthma (n = 106) and allergic rhinitis (n = 99) and 83 healthy peers were included in this study. We evaluated PAI-1 4G/5G polymorphism genotype as well as the possible association between PAI-1 4G/5G polymorphism and pulmonary function tests, serum total immunoglobulin E (IgE), total eosinophil count, and skin-prick test positivity in our study. The prevalence of the 4G allele significantly exceeded the values found in the controls both in patients with asthma (p = 0.001) and in patients with allergic rhinitis (p = 0.002). Interestingly, comparison of asthmatic patients revealed that mean baseline percent forced expiratory volume in 1 second and forced vital capacity were significantly higher in patients who bear 5G/5G genotype than in those who have 4G/4G or 4G/5G genotypes. No statistically significant relationship were found between PAI-1 polymorphism and total serum IgE levels, total eosinophil count, or selected skin test responses to aeroallergens. Our study suggests that Turkish children with asthma or allergic rhinitis have a higher prevalence of PAI-1 4G allele compared with their healthy peers.

    Prostaglandin D2(PGD2) is involved in the pathogenesis of allergic rhinitis. However, the sensory nervous system-mediated contributions of PGD2to the symptoms of allergic rhinitis remain unclear. We investigated the involvement of PGD2in these symptoms and in neuronal excitation by in vivo and ex vivo experiments. In an ovalbumin-induced model of allergic rhinitis in guinea pigs, the number of sneezing, nasal rubbing, and nasal secretion events were assessed after the nasal cavity instillation of PGD2, histamine, or a combination of PGD2and histamine. In situ hybridization for PGD2receptor 1 (DP1) mRNA transcripts and immunohistochemical analysis of histamine H1receptor protein expression in guinea pig trigeminal ganglion (TRG) were performed. The effects of DP1receptor activation on the excitability of TRG neurons to electrical and histamine stimuli were assessed using whole-cell patch-clamp recordings. Histamine induced more sneezing, nasal rubbing, and nasal secretion events than PGD2 PGD2augmented histamine-induced responses, whereas pretreatment with a DP1receptor-selective antagonist completely suppressed PGD2-induced augmentation. DP1receptor mRNA transcripts and H1receptor protein expression could be detected in TRG neurons. Moreover, a DP1receptor agonist caused significant increases in the number of histamine-induced action potentials and depolarization, and reduced the current threshold in small-diameter neurons. Our findings show that PGD2-DP1receptor signaling augments the symptoms of allergic rhinitis via the sensory nervous system by modulating nasal neuronal activation to various stimuli, such as histamine. These findings suggest that DP1receptor antagonist has therapeutic potential for the treatment of allergic rhinitis.

    Allergic rhinitis, a frequently occurring immunological disorder affecting men, women and children worldwide, is a state of hypersensitivity that occurs when the body overreacts to a substance such as pollen, mold, mites or dust. Allergic rhinitis exerts inflammatory response and irritation of the nasal mucosal membranes leading to sneezing; stuffy/runny nose; nasal congestion; and itchy, watery and swollen eyes. A novel, safe polyherbal formulation (Aller-7/NR-A2) has been developed for the treatment of allergic rhinitis using a unique combination of extracts from seven medicinal plants including Phyllanthus emblica, Terminalia chebula, Terminalia bellerica, Albizia lebbeck, Piper nigrum, Zingiber officinale and Piper longum. In this study, the antioxidant efficacy of Aller-7 was investigated by various assays including hydroxyl radical scavenging assay, superoxide anion scavenging assay, 1,1-diphenyl-2-picryl hydrazyl (DPPH) and 2,2-azinobis-ethyl-benzothiozoline-sulphonic acid diammonium salt (ABTS) radical scavenging assays. The protective effect of Aller-7 on free radical-induced lysis of red blood cells and inhibition of nitric oxide release by Aller-7 in lipopolysaccharide-stimulated murine macrophages were determined. Aller-7 exhibited concentration-dependent scavenging activities toward biochemically generated hydroxyl radicals (IC50 741.73 microg/ml); superoxide anion (IC50 24.65 microg/ml by phenazine methosulfate-nicotinamide adenine dinucleotide [PMS-NADH] assay and IC50 4.27 microg/ml by riboflavin/nitroblue tetrazolium [NBT] light assay), nitric oxide (IC50 16.34 microg/ml); 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical (IC50 5.62 microg/ml); and 2,2-azinobis-ethyl-benzothiozoline-sulphonic acid diammonium salt (ABTS) radical (IC50 7.35 microg/ml). Aller-7 inhibited free radical-induced hemolysis in the concentration range of 20-80 microg/ml. Aller-7 also significantly inhibited nitric oxide release from lipopolysaccharide-stimulated murine

    The prevalence of allergic diseases is increasing globally, most particularly in middle- to low-income countries. This article examines the burden of allergic rhinitis and chronic urticaria in the Asia-Pacific region, unmet clinical needs, and the potential role of bilastine in the management of these conditions. An International Advisory Group meeting was convened in association with the Asian Pacific Society of Respirology Annual Congress in November 2014, followed by a literature review, and consensus-based outcomes from the meeting and literature review are described. Regional estimates of the prevalence of allergic rhinitis range from 10% to 50%, while little is known regarding the burden of urticaria in the Asia-Pacific region. A survey of allergy patients in the region identified fast, complete, and long-lasting symptom relief as the medication attributes most important to patients. International treatment guidelines for allergic rhinitis and urticaria advocate the first-line use of second-generation, no-sedating H1-antihistamines, such as bilastine, over their first-generation counterparts and a range of these agents are available to Asia-Pacific patients. The newer agents possess many of the properties of an "ideal" antihistamine (once daily administration, rapid and complete symptom relief, limited potential for drug-drug interactions, minimal side effects). The burgeoning prevalence of allergic diseases in the Asia-Pacific region and the uncontrolled symptoms that these patients experience demand a new antihistamine that offers the highest number of positive features according to the international guidelines.

    Allergic rhinitis (AR) is one of the common disorders in airway allergic inflammation. The pathogenesis of AR is unclear. It is accepted that immune deregulation is associated with the pathogenesis of AR. Recent reports suggest that a large number of micro RNAs (miR) can regulate immune functions. This study aims to investigate the role of miR-146a in an enforcing immunotherapy of AR. In this study, a mouse AR model was created. The levels of miR-146a in the mouse nasal mucosa were assessed by real time RT-PCR. A specific immunotherapy was performed in AR mice. The results showed that the AR mice had an AR-like inflammation in the nasal mucosa. Compared with naïve mice, markedly lower levels of miR-146a were detected in AR mice. The co-administration with miR-146a significantly enforced the effect of ovalbumin (OVA)-specific immunotherapy on inhibition of AR inflammation in the nasal mucosa. Further analysis showed that miR-146a induced transforming growth factor-β in dendritic cells; the latter induced naïve CD4(+) T cells to differentiate into regulatory T cells. In conclusion, miR-146a can enforce OVA-specific immunotherapy via inducing antigen-specific regulatory T cells. miR-146a may have therapeutic potential to be used in the immunotherapy of allergic diseases.

    The development of atopic dermatitis (AD) in infancy and subsequent allergic rhinitis and asthma in later childhood is known as the atopic march. This progressive atopy is dependent on various underlying factors such as the presence of filaggrin mutations as well as the time of onset and severity of AD. Clinical manifestations vary among individuals. Previously it was thought that atopic disorders may be unrelated with sequential development. Recent studies support the idea of a causal link between AD and later onset atopic disorders. These studies suggest that a dysfunctional skin barrier serves as a site for allergic sensitization to antigens and colonization of bacterial super antigens. This induces systemic Th2 immunity that predisposes patients to allergic nasal responses and promotes airway hyper reactivity. While AD often starts early in life and is a chronic condition, new research signifies that there may be an optimal window of time in which targeting the skin barrier with therapeutic interventions may prevent subsequent atopic disorders. In this review we highlight recent studies describing factors important in the development of atopic disorders and new insights in our understanding of the pathogenesis of the atopic march.

    The potential of Pycnogenol for relieving allergic rhinitis (birch pollen) symptoms was explored in a double-blind, placebo-controlled trial. In 2008 19 subjects started treatment 3 weeks prior to the onset of birch pollen season in Ontario, Canada. While there was an improvement of eye and nasal symptoms with Pycnogenol, there was no significance versus placebo. It was postulated that Pycnogenol may require a lag-time between the start of therapy and the onset of action. Therefore 39 subjects were treated 5-8 weeks prior to the 2009 birch allergy season. The evaluation of subjects in 2009 showed much lower scores for eye (-35%) and nasal (-20.5%) symptoms with Pycnogenol compared with placebo. In succession of the allergy season birch specific IgE increased by 31.9% in the placebo group compared with only 19.4% in the Pycnogenol group. Detailed analysis suggested that symptom-relief was better the longer subjects were on Pycnogenol prior to the allergen exposure. The best results were found with subjects who took Pycnogenol 7-8 weeks ahead of the allergy season. With the limited number of 39 patients statistical predications were unattainable. In conclusion, Pycnogenol improved allergic rhinitis symptoms when supplementation was started at least 5 weeks before the onset of the allergy season.

    Little data on UK prescribing patterns and treatment effectiveness for allergic rhinitis (AR) are available. We quantified unmet pharmacologic needs in AR by assessing AR treatment effectiveness based on the prescribing behaviour of UK general practitioners (GP) during two consecutive pollen seasons (2009 and 2010). We conducted a retrospective observational study with the data from the Optimum Patient Care Research Database. We assessed diagnoses and prescription data for patients with a recorded diagnosis of rhinitis who took rhinitis medication during the study period. We assessed the data from 25,069 patients in 2009 and 22,381 patients in 2010. Monotherapy was the initial prescription of the season for 67% of patients with seasonal AR (SAR) and 77% of patients with nonseasonal upper airways disease (NSUAD), for both years. Initial oral antihistamine (OAH) or intranasal corticosteroid (INS) monotherapy proved insufficient for >20% of SAR and >37% of NSUAD patients. Multiple therapy was the initial prescription for 33% of SAR and 23% of NSUAD in both years, rising to 45% and >50% by season end, respectively. For NSUAD, dual-therapy prescriptions doubled and triple-therapy prescriptions almost tripled during both seasons. Many patients revisited their GP regardless of initial prescription. Initial OAH or INS monotherapy provides insufficient symptom control for many AR patients. GPs often prescribe multiple therapies at the start of the season, with co-prescription becoming more common as the season progresses. However, patients prescribed multiple therapies frequently revisit their GP, presumably to adjust treatment. These data suggest the need for more effective AR treatment and management strategies.

    Epidemiologic studies suggest that the prevalence of allergic rhinitis (AR) is rising worldwide. Several reports, in fact, indicate increasing trends in the prevalence of AR especially in developing countries, likely related to the environment and climate changes and the adoption of an urbanized Western lifestyle. The primary objective of the present study was to collect information about management in real-life settings, including a characterization of typical patients' profile referring to physicians, the disease features, the common approaches to diagnostic assessments and therapeutic decisions. This was an international, multicenter, cross-sectional study conducted in adults or children (≥6 years) suffering from rhinitis confirmed by physician's diagnosis for at least one year. The 234 physicians who participated in the study included a total of 2778 patients in Egypt, Mexico, Brazil, Colombia, Guatemala, Iran, Venezuela, Argentina, Israel, Kuwait and United Arab Emirates. It was found that clinical history was the selected tool to diagnose and categorize AR patients (97.1%), with less than half of patients undergoing allergy testing, may be explaining the scarce use of immunotherapy on management of disease. Out of 2776 patients, 93.4% had somehow received a recommendation to avoid allergens and irritant agent exposure. Notably, 91.4% were receiving at least one treatment at the time of the survey, mostly oral antihistamines (79.7%) and intranasal corticosteroids (66.3%). Oral antihistamines, intranasal steroids and decongestants were considered both safe and effective by patients and physicians, preferring oral and nasal route of administration. The ISMAR registry was designed according to the most accepted epidemiological recommendations, and provides interesting information regarding the management of rhinitis from a patient and physician points of view, with many similarities between the participating countries. Further efforts are required to better

    Specific immunotherapy (SIT) reverses the symptoms of seasonal allergic rhinitis (SAR) in most patients. Recent studies report type I interferons shifting the balance between type I T helper cell (Th1) and type II T helper cells (Th2) towards Th2 dominance by inhibiting the differentiation of naive T cells into Th1 cells. As SIT is thought to cause a shift towards Th1 dominance, we hypothesized that SIT would alter interferon type I signaling. To test this, allergen and diluent challenged CD4(+) T cells from healthy controls and patients from different time points were analyzed. The initial experiments focused on signature genes of the pathway and found complex changes following immunotherapy, which were consistent with our hypothesis. As interferon signaling involves multiple genes, expression profiling studies were performed, showing altered expression of the pathway. These findings require validation in a larger group of patients in further studies.

    Specific immunotherapy (SIT) reverses the symptoms of seasonal allergic rhinitis (SAR) in most patients. Recent studies report type I interferons shifting the balance between type I T helper cell (Th1) and type II T helper cells (Th2) towards Th2 dominance by inhibiting the differentiation of naive T cells into Th1 cells. As SIT is thought to cause a shift towards Th1 dominance, we hypothesized that SIT would alter interferon type I signaling. To test this, allergen and diluent challenged CD4+ T cells from healthy controls and patients from different time points were analyzed. The initial experiments focused on signature genes of the pathway and found complex changes following immunotherapy, which were consistent with our hypothesis. As interferon signaling involves multiple genes, expression profiling studies were performed, showing altered expression of the pathway. These findings require validation in a larger group of patients in further studies. PMID:28097155

    Background: Increasing interest in sublingual immunotherapy (SLIT) among practitioners and patients has resulted in numerous publications and clinical trials in recent years. With the clinical growth of SLIT, discussions of its efficacy, safety, and immunologic effects have intensified, as have comparisons to subcutaneous immunotherapy (SCIT). In the United States, SCIT has been the traditional form of immunotherapy for inhalant allergy and is the only immunotherapy method approved by the U.S. Food and Drug Administration at this time. The similarities and differences between SLIT and SCIT are often discussed, yet clinical studies directly comparing these immunotherapy methods are scarce. Methods: A literature review of specific issues and controversies between SLIT and SCIT for allergic rhinitis was conducted. Results: Safety, efficacy, and immunologic effects of these two immunotherapy techniques are reviewed. Conclusion: Unanswered questions relating to SLIT are examined. PMID:22391071

    Context • Allergies are a common affliction, whether they are respiratory, food related, or dermatological. People often resort to continuous use of over-the-counter medications, such as antihistamines, to manage their symptoms. Controversy still remains over testing serum immunoglobulin (Ig) G to diagnose food allergies. Objective • This study intended to examine the benefits of treatment of a pediatric patient with natural supplements and an elimination diet for IgG food allergies. Design • The research team reported a case study. Setting • The study was conducted at Southwest Naturopathic Medical Center (Tempe, AZ, USA). Participant • The participant was a 10-y-old Caucasian female who had diagnoses of allergic rhinitis and reactive bronchospasm, the second of which was exacerbated by allergens such as wheat, perfumes, and seasonal flora. Intervention • Following testing for IgE- and IgG-reactive foods, the patient was treated with natural supplements to reduce her allergic responses and was instructed to make dietary changes to eliminate the IgG-reactive foods. Outcome Measures • The patient's symptom severity was tracked starting 1 mo after her initial visit to Southwest Naturopathic Medical Center. The severity was based on the patient's subjective reports about her congestion to her mother and on her mother's observations of the effect of symptoms on her attention and school performance. The bronchospasm severity was based on the frequency of a sensation of wheezing and chest tightness, the frequency of inhaler use, and the occurrence of any exacerbation of symptoms with acute respiratory illness Results • After 1 mo, in which the patient used the natural supplements, she experienced a 90% improvement in coughing; a 70% improvement in nasal congestion; less chest tightness; and no need for use of loratadine, diphenhydramine, or albuterol. At the 8-mo follow-up visit, her nasal congestion was reported to be entirely gone. Conclusions • The

    The elevated incidence of short stature (body height < (-)x - 2s), skeletal retardation and delayed puberty in children with bronchial asthma or atopic dermatitis is generally attributed to the severity of the disorder. However, a series of findings indicate a causal influence of the atopy and the existence of atopic skeletal retardation per se.The observation that children with atopic disorders, whether bronchial asthma, atopic dermatitis or allergic rhinitis, exhibit a rate of short stature that is twice to five times higher than normal indicates atopic and thus genetically determined influences. The elevated prevalence of short stature associated with allergic rhinitis is especially significant, as this disorder cannot be included among the severe chronic disorders. The fact that skeletal retardation is more prevalent in boys than in girls by a ratio of about 2:1 and that a significantly more marked retardation of bone maturation is found in atopic in comparisons with non-atopic asthmatics also lend support to this postulation. The clinical relevance of atopic growth retardation is also supported by the close interaction of pathophysiological basal mechanisms of bone metabolism and the atopy status. Thus the local growth factor prostaglandin E(2) (PGE(2)), which is important for bone metabolism, is also a messenger substance for the immediate and late allergic reaction. The platelet-activating factor (PAF), as one of the strongest mediators in the pathogenesis of allergic disorders, influences the PGE(2) synthesis in the osteoblasts. These relationships show that atopy-dependent imbalances in the complex system of local and systemic growth factors can certainly lead to disturbance of skeletal maturation which may delay growth and development in atopic children. In order to verify these assumptions it is necessary to research the interaction of local growth factors (particularly the roles of PGE(2), PAF and IGF I) in the skeletons of children of short stature

    In the current study, we sought to investigate whether lysed Enterococcus faecalis FK-23 (LFK), a heat-killed probiotic preparation, attenuated eosinophil influx into the upper airway and had immunomodulatory activity in a murine allergic rhinitis model. Eighteen BALB/c mice were divided into three groups; the ovalbumin (OVA)-sensitized/challenged group, which received saline orally for 6 weeks (OVA group), the OVA-sensitized/challenged group, which received LFK orally for 6 weeks (LFK-fed group), and the non-sensitized group, which received saline for 6 weeks (saline control group). Nasal rubbing and sneezing were monitored during the study. After the final challenge, interleukin (IL)-4, interferon (IFN)-γ, and OVA-specific IgE levels in the sera and splenocyte culture supernatants were determined, eosinophilic infiltrate into the upper airway was quantified, and splenic CD4+CD25+ regulatory T cells (Tregs) were examined by flow cytometry. We found that nasal rubbing was significantly reduced in LFK-fed mice compared to the OVA group on d 27 and 35, and sneezing was significantly inhibited by LFK administration for 35 d. LFK-fed mice had significantly less eosinophil influx into the nasal mucosa than the OVA group. There were no significant differences between the LFK-fed group and OVA group in the serum and splenocyte culture supernatant levels of IL-4, IFN-γ, and OVA-specific IgE. Interestingly, the LFK-fed mice had a significantly greater percentage of splenic CD4+CD25+ Tregs than OVA group. Our results indicate that oral administration of LFK may alleviate nasal symptoms, reduce nasal eosinophilia, and increase the percentage of CD4+CD25+ Tregs in experimental allergic rhinitis.

    Aims To conduct a randomized placebo controlled double-blind crossover trial in order to evaluate a loratadine-pseudoephedrine combination (L+PS) in children with seasonal allergic rhinitis. Methods Forty children (15 males; 25 females), aged 3–15 years, were included in this study. They were randomized to receive L+PS (0.2 mg kg−1 body weight–2.4 mg kg−1 body weight respectively) or placebo (PLA) for 14 days. After 7 days of washout, patients were shifted to the other treatment for a further 14 days. Nasal symptoms (sneezing/itching, congestion, nasal dripping) and signs (turbinal swelling, retronasal drainage), rated on a scale ranging from: 1. absent to 5. very intense, and their sum or mean total symptom score (MTSS) were used as efficacy measurement. Results Significant relief was observed; post-treatment MTSS difference and its percent change were respectively; L+PS = −4.29; 95% CI: −3.64 and −4.94 (27.8%), and PLA = −1.63; 95% CI: −0.95 and −2.31 (10.7%) (P < 0.001 baseline vs endpoint and between treatments). Furthermore, L+PS and PLA significantly modified symptoms, but only L+PS significantly modified signs. No clinical changes were observed during the trial; only one patient showed slight transient insomnia when receiving L+PS. Conclusions It is concluded that L+PS is useful and well tolerated in children with seasonal allergic rhinitis. However, elements such as placebo effect must be taken into account for planning future trials. PMID:9491827

    Background Hypoxia-inducible factor 1α (HIF-1α) is an important regulator of immune and inflammatory responses. We hypothesized that nasal allergic inflammation is attenuated by HIF-1α inhibition and strengthened by HIF-1α stabilization. Objective To elucidate the role of HIF-1α in a murine model of allergic rhinitis (AR). Methods Mice were pretreated with the HIF-1α inhibitor 2-methoxyestradiol (2ME2) or the HIF-1α inducer cobalt chloride (CoCl2) in an established AR murine model using ovalbumin (OVA)-sensitized BALB/c mice. HIF-1α and vascular endothelial growth factor (VEGF) expression in nasal mucosa was measured and multiple parameters of allergic responses were evaluated. Results HIF-1α and VEGF levels were locally up-regulated in nasal mucosa during AR. Inflammatory responses to OVA challenge, including nasal symptoms, inflammatory cell infiltration, eosinophil recruitment, up-regulation of T-helper type 2 cytokines in nasal lavage fluid, and serum OVA-specific IgE levels were present in the OVA-challenged mice. 2ME2 effectively inhibited HIF-1α and VEGF expression and attenuated the inflammatory responses. Stabilization of HIF-1α by CoCl2 facilitated nasal allergic inflammation. HIF-1α protein levels in nasal airways correlated with the severity of AR in mice. Conclusions HIF-1α is intimately involved in the pathogenesis of nasal allergies, and the inhibition of HIF-1α may be useful as a novel therapeutic approach for AR. PMID:23133644

    A 20-year-old woman with a proven allergy to camomile suffered from short-lasting rhinitis when using a camomile-scented toilet paper. The prick-by-prick test performed with the toilet paper was positive. Diagnosis was confirmed by a challenge test that also resulted positive. This is the first reported case of toilet-paper-induced acute rhinitis. The removal of the toilet paper from the bathroom was sufficient to obtain the disappearance of symptoms. Patients allergic to camomile should avoid a camomile-scented toilet paper.

    Allergic diseases are frequent in children and their prevalence and severity differ in the different regions of the world. The association between pet ownership in childhood and subsequent asthma and sensitization is very controversial.In our survey conducted with standardized method (International Study of Asthma and Allergies in Childhood), 3200 children 6-7 years old were questioned regarding asthma, allergic rhinitis and eczema. The prevalence of Attacks and shortness of breath with wheezing during last 12 months in the children who had exposure to pets in the first year of life was 34.3% 'that was less than children who had not exposure (OR=3.06, 95% confidence interval [CI] 1.14-8.21, P=0.021). Also during the past 12 months the prevalence of night dry coughs, allergic rhinitis symptoms and eczema symptoms in those who had pet exposure in the first year of their life was lower than the children did not have it. However there was no significant difference in some other symptoms of asthma in two groups.Our findings suggest that pet exposure in the first year of life can have a protective effect on asthma, allergic rhinitis and eczema.

    We assessed the efficacy of loratadine syrup compared with cyproheptadine HCl solution for treating children aged from 2 to 12 years with perennial allergic rhinitis (PAR) in Taiwan. Sixty children with mite-induced PAR were enrolled and randomly placed into two treatment groups: loratadine syrup or cyproheptadine HCl solution. Treatment efficacy and symptom changes from baseline to post-treatment were evaluated by total symptom scores and visual analogue scales (VAS) during a 2-week period. There were no differences in age, gender, height, or weight between the two groups. After 2 weeks of treatment, there was a significantly greater reduction in symptom scores in the loratadine group than in the cyproheptadine group (p<0.001). Clinical and subjective VAS showed significant differences in percentage changes from baseline between the loratadine and cyproheptadine groups at all time points (all p<0.001, in favor of loratadine). Clinical VAS change at week 1: 95.1 vs 11.3; subjective VAS change at week 1: 88.6 vs 13.6; clinical VAS change at week 2: 125.5 vs 18.3; subjective VAS change at week 2: 101.4 vs 7.1. Thus, loratadine was superior to cyproheptadine for alleviating both nasal and non-nasal symptoms of perennial allergic rhinitis in Taiwanese children aged 2-12 years.

    As standard drug treatment of allergic rhinitis (AR) is not completely satisfactory, allergen immunotherapy (AIT) represents the only current treatment with the potential to modify the natural history. House dust mite (HDM) allergy is very common. The aim of the current experience was to describe the clinical profile of HDM-allergic patients with AR who received AIT in a real world model, such as allergy clinics. Globally, 239 patients (126 adults and 113 children; 107 females and 132 males; mean age 21 years, age range 6-56 years) were evaluated. AIT was prescribed in 59 patients (24.7%), 44 adults (35%) and 15 children (13.3%). The current findings deriving from this real world multicentre study are consistent with previous investigations on HDM-AIT and define some clinical characteristics of the eligible candidate to this treatment. In fact, severity of ocular-nasal symptoms and over-use of symptomatic medications may typify the ideal candidate to HDM-AIT and SLIT was the preferred choice.

    2014-01-01

    Background Oral antihistamines that target the histamine receptor–1, such as fexofenadine, offer suboptimal relief of allergic rhinitis-associated nasal congestion. Combinations with oral sympathomimetics, such as pseudoephedrine, relieve congestion but produce side effects. Previous animal and human studies with histamine receptor-3 antagonists, such as PF-03654764, demonstrate promise. Methods Herein we employ the Environmental Exposure Unit (EEU) to conduct the first randomized controlled trial of PF-03654764 in allergic rhinitis. 64 participants were randomized in a double-blind, placebo-controlled 4-period crossover study. Participants were exposed to ragweed pollen for 6 hours post-dose in the EEU. The primary objective was to compare the effect of PF-03654764 + fexofenadine to pseudoephedrine + fexofenadine on the subjective measures of congestion and Total Nasal Symptom Score (TNSS). The objectives of our post-hoc analyses were to compare all treatments to placebo and determine the onset of action (OA). This trial was registered at ClinicalTrials.gov (NCT01033396). Results PF-03654764 + fexofenadine was not superior to pseudoephedrine + fexofenadine. In post-hoc analyses, PF-03654764 + fexofenadine significantly reduced TNSS, relative to placebo, and OA was 60 minutes. Pseudoephedrine + fexofenadine significantly reduced congestion and TNSS, relative to placebo, with OA of 60 and 30 minutes, respectively. Although this study was not powered for a statistical analysis of safety, it was noted that all PF-03654764-treated groups experienced an elevated incidence of adverse events. Conclusions PF-03654764 + fexofenadine failed to provide superior relief of allergic rhinitis-associated nasal symptoms upon exposure to ragweed pollen compared to fexofenadine + pseudoephedrine. However, in post-hoc analyses, PF-03654764 + fexofenadine improved TNSS compared to placebo. Side effects in the PF-03654764-treated groups were

    Background: Allergic diseases substantially affect human health and social economy. The pathogenesis is to be further understood. The effect of current therapeutic remedies on allergic diseases is not satisfactory. Aims: This study aimed to inhibit allergic rhinitis in a mouse model with a Chinese traditional medical prescription, Bu-Zhong-Yi-Qi-Tang. Material and Methods: A mouse AR model was developed with ovalbumin (OVA) plus adjuvant alum. The AR clinical symptoms and immune pathology in the nasal mucosa were assessed with the AR mouse model. Some mice were treated with Bu-Zhong-Yi-Qi-Tang via gavage-fed. The immune tolerance status in the nasal mucosa was evaluated by counting the numbers of tolerogenic dendritic cells (DC) and regulatory T cells (Treg). Results: After exposure to the specific antigen, OVA, the sensitized mice had AR-like symptoms including nasal itch and sneeze. The frequency of mast cells, levels of IgE/IL-4 in nasal mucosa was markedly higher in sensitized mice than naïve controls; while the levels of integration alphavbeta6 (avb6), the number of tolerogenic DCs and Tregs in nasal mucosa were significantly lower than naïve control mice. The AR-like symptoms and immune pathology and immune tolerance status in the AR nasal mucosa were substantially improved by administration with Bu-Zhong-Yi-Qi-Tang. Conclusions: The immune tolerance status is impaired in the AR nasal mucosa that can be improved by administering with Bu-Zhong-Yi-Qi-Tang. PMID:22361496

    Allergic rhinitis (AR) is the leading cause of consultation at the allergy specialist's office, but detailed, reliable, and validated clinical data on this condition are limited. This study was designed to define the clinical features, diagnostic methods, and therapeutic approaches of patients with AR induced by grass pollen in Spain. Two hundred twelve specialists participated in a multicenter, observational, epidemiologic, questionnaire-based study. Each investigator had to recruit at least two patients consulting for the first time and with a diagnosis of AR induced by grass pollen. Five hundred twenty-four patients (52% men; mean age, 29.3 years) with grass pollen-induced rhinitis (mean disease duration, 8.7 years) were recruited. Just 18.4% of patients reported that their symptom status had improved since the beginning of the condition, 89.4% had moderate-severe rhinitis (Allergic Rhinitis and Its Impact on Asthma classification) and 35.1% had concomitant bronchial asthma. For 52.1% of patients, control of symptoms with previous drug treatment was poor. Most of the patients were polysensitized to other pollens (sensitization to olive tree pollen, 57.1%). Oral antihistamines (97.3%) and nasal corticosteroids (82.3%) were the most frequently prescribed drugs and 43.1% of patients received specific immunotherapy. The clinical profile for the majority of Spanish patients consulting an allergy specialist for AR induced by grass pollen corresponds to a young adult with a lengthy moderate-severe rhinitis, often accompanied by bronchial asthma. Their symptoms progressively worsen and rhinitis is poorly controlled by symptomatic treatment. Oral antihistamines and nasal corticosteroids are the most frequently used therapeutic approaches and less than one-half receive specific immunotherapy.

    The efficacy and safety of the nasally administered histamine H1 receptor blocking drug Azelastine was investigated in an open, multicenter, randomized comparative trial with Ebastine in seasonal allergic rhinitis. 110 patients in two parallel groups were treated for 14 days and efficacy was assessed by the physician using a rating scale measuring 10 nasal and ocular symptoms of seasonal rhinitis (0 = absent, 1 = mild, 2 = moderate, 3 = severe). Tolerability was measured on the basis of reported adverse events. Both treatment groups had dramatic reductions in the physician's total symptom score following treatment (p < 0.0005). There was no significant difference between the two groups. Changes in individual rhinitis symptoms showed no differences between the two groups. During treatment, 19 patients had at least one adverse event, 13 in Azelastine group and 6 in Ebastine group; all were mild. The most frequent adverse events reported were somnolence (4 cases in Ebastine group) and a bitter taste (4 patients in the Azelastine group). In conclusion, the results of the study on 110 patients suggest that both Azelastine and Ebastine are effective treatments of the symptoms of seasonal allergic rhinitis. Both drugs were well tolerated.

    The aim was to determine the effect of feeding and oral habits, toothbrushing, socioeconomic status and allergic rhinitis on the development of dental caries in primary dentition. In a cross-sectional study, data were obtained by means of a structured questionnaire on 1,160 children, 4-5 years old (mean = 4.5 +/- 0.5) and born in 1999, 2000 or 2001. The children also had a physical examination by an allergist and dentists. Dental caries was diagnosed according to WHO criteria. Caries experience was measured as number of deft and defs. Logistic regression analysis assessed the association between dental caries and independent variables. The dental caries prevalence was 17.9%, 28.8% of the children had allergic rhinitis symptoms, digit sucking was reported by 9.8% and pacifier use by 13.6% of the children. The mean number of deft of the sample was 1.02 (SD = 2.37) and that of defs was 1.33 (SD = 3.54). Analysis showed that breast-feeding for >12 months (p < 0.01), toothbrushing frequency (p < 0.01), sugar consumption (p < 0.01) and pacifier use (p < 0.01) each had a significant association with dental caries occurrence in primary dentition. Children with pacifier use and allergic rhinitis had more than double the risk of dental caries development. Allergic rhinitis alone has no effect on dental caries. Healthcare professionals attempting to limit dental caries should consider the effect of prolonged breast-feeding, sugary product consumption between meals and nonnutritive habits on dental caries.

    To make a systematic study on acupoints selection and medication rules for allergic rhinitis treated with acupoint application, literature regarding clinical researches on acupoint application for allergic rhinitis since 2000 has been retrieved; medication and acupoints involved were preprocessed and cluster analysis technique was applied to classify the data. As a result, a total of 37 pieces of literature were included, involving 27 types of herbs and 33 acupoints. The results showed Baijiezi (Brassica alba Boiss), Xixin (Radix et Rhizoma Asari), Gansui (Radix Kansui), Yanhusuo (Corydalis), Jiangzhi (Ginger juice) and Baizhi (Radix angelicae) constituted the main herb prescription, and the layer was increased along with frequency of use. Feishu (BL 13), Dazhui (GV 14), Shenshu (BL 23), Pishu (BL 20), Gaohuang (BL 43), Fengmen (BL 12) constituted the main acupoint prescription, which were clustered into 4 classes; Feishu (BL 13) and Dazhui (GV 14) constituted the first class; Pishu (BL 20) and Shenshu (BL 23) constituted the second class; the first and second class merged into the third class, Including Feishu (BL 13), Dazhui (GV 14), Shenshu (BL 23) and Pishu (BL 20); Gaohuang (BL 43) and Fengmen (BL 12) constituted the fourth class; the fourth class and the third class constituted the whole acupoint prescription. It was showed that for the allergic rhinitis treated with acupoint application, the medication was mainly epispastic herbs with pungent nature that belonged to the lung, spleen and kidney meridian, which presented the principle of simultaneous treatment of principal and subordinate symptoms; also the medication can be selected from core layer to supporting layer based on clinical needs; for the selection of acupoints, acupoints in lung and bladder meridian were mainly selected to assist exterior and resist the pathogenic qi, which could treat allergic rhinitis fundamentally by joint use with acupoints in soleen and kidney meridian.

    Classical literature indicates that acupuncture has been used for millennia to treat numerous inflammatory conditions, including allergic rhinitis. Recent research has examined some of the mechanisms underpinning acupuncture's anti-inflammatory effects which include mediation by sympathetic and parasympathetic pathways. The hypothalamus-pituitary-adrenal (HPA) axis has been reported to mediate the antioedema effects of acupuncture, but not antihyperalgesic actions during inflammation. Other reported anti-inflammatory effects of acupuncture include an antihistamine action and downregulation of proinflammatory cytokines (such as TNF-α, IL-1β, IL-6, and IL-10), proinflammatory neuropeptides (such as SP, CGRP, and VIP), and neurotrophins (such as NGF and BDNF) which can enhance and prolong inflammatory response. Acupuncture has been reported to suppress the expression of COX-1, COX-2, and iNOS during experimentally induced inflammation. Downregulation of the expression and sensitivity of the transient receptor potential vallinoid 1 (TRPV1) after acupuncture has been reported. In summary, acupuncture may exert anti-inflammatory effects through a complex neuro-endocrino-immunological network of actions. Many of these generic anti-inflammatory effects of acupuncture are of direct relevance to allergic rhinitis; however, more research is needed to elucidate specifically how immune mechanisms might be modulated by acupuncture in allergic rhinitis, and to this end a proposed model is offered to guide further research.

Other reported anti-inflammatory effects of acupuncture include an antihistamine action and downregulation of proinflammatory cytokines (such as TNF- α , IL-1 β , IL-6, and IL-10), proinflammatory neuropeptides (such as SP, CGRP, and VIP), and neurotrophins (such as NGF and BDNF) which can enhance and prolong inflammatory response. Acupuncture has been reported to suppress the expression of COX-1, COX-2, and iNOS during experimentally induced inflammation. Downregulation of the expression and sensitivity of the transient receptor potential vallinoid 1 (TRPV1) after acupuncture has been reported. In summary, acupuncture may exert anti-inflammatory effects through a complex neuro-endocrino-immunological network of actions. Many of these generic anti-inflammatory effects of acupuncture are of direct relevance to allergic rhinitis; however, more research is needed to elucidate specifically how immune mechanisms might be modulated by acupuncture in allergic rhinitis, and to this end a proposed model is offered to guide further research.

    Background. The Sanfu herbal patch (SHP) has been widely used to treat allergic rhinitis (AR) in China. SHP has been reported to be effective for managing the symptoms of AR, but the evidence suffers from methodological limitations. Therefore, we designed a three-armed, randomized, and placebo-controlled trial to evaluate the efficacy and safety of SHP for persistent allergic rhinitis (PAR). Methods. The trial consists of 5 treatment sessions along with a one-year follow-up. This process is then repeated in the second and third years. Eligible participants diagnosed with PAR were randomized at a ratio of 2 : 2 : 1 into one of three groups: (a) SHP group; (b) placebo group; or (c) waiting-list group. The waiting-list group will receive no treatment in the first year but will receive SHP in the following two years. The primary outcome, total nasal symptoms score, is self-assessed at the beginning of each treatment session and during each annual follow-up. Secondary outcomes include the Rhinoconjunctivitis Quality-of-Life Questionnaire, allergic rhinitis attacks, and relief medications. The trial will be stopped if early termination criteria are met during the interim analysis. Ethics. This protocol has been approved by site ethics committee (number B2014-014-01) and is registered with ClinicalTrials.gov NCT02192645. PMID:26300945

    Few published studies have looked at the health effects of air pollution in the primary care setting, and most have concentrated on lower rather than upper respiratory diseases. The authors investigated the association of daily consultations with general practitioners for allergic rhinitis with air pollution in London, United Kingdom. Generalized additive models were used to regress time series of daily numbers of patients consulting for allergic rhinitis against 1992--1994 measures of air pollution, after control for possible confounders and adjustment for overdispersion and serial correlation. In children, a 10th--90th percentile increase in sulfur dioxide (SO(2)) levels 4 days prior to consultation (13-31 microg/m(3)) was associated with a 24.5% increase in consultations (95% confidence interval: 14.6, 35.2; p < 0.00001); a 10th--90th percentile increase in averaged ozone (O(3)) concentrations on the day of consultation and the preceding 3 days (6--29 parts per billion) was associated with a 37.6% rise (95% confidence interval: 23.3, 53.5; p < 0.00001). For adults, smaller effect sizes were observed for SO(2) and O(3). The association with SO(2) remained highly significant in the presence of other pollutants. This study suggests that air pollution worsens allergic rhinitis symptoms, leading to substantial increases in consultations. SO(2) and O(3) seem particularly responsible, and both seem to contribute independently.

    Background: Allergic rhinitis is characterized by a chronic inflammation of nasal mucosa and represents a risk factor for asthma occurrence. H1 antihistamines reduce the symptoms of rhinitis, but some compounds may have anti-inflammatory properties. Aims: We evaluated the plasma level of some cytokines in patients with persistent allergic rhinitis (PAR) and their evolution after a 4-week treatment with H1 anti-histamines, as well as the risk of asthma after 1.5 years. Study Design: Randomized clinical trial. Methods: Eighty-five patients with PAR and 30 healthy volunteers were included in the study. The patients with PAR were randomly divided into 2 groups: 41 patients treated with 5 mg/day desloratadine and 44 patients under 5 mg/day levocetirizine for 4 weeks. The clinical and biological evaluations were performed before and after treatment and included rhinitis symptoms and total symptoms score, type of sensitization, and plasmatic levels of total IgE, IL-1β, IL-6, IL-8 and TNF-α. Results: IL-8 and TNF-α were significantly increased in patients with PAR compared to healthy volunteers (5.85 vs 3.12, p<0.001 and 2.32 vs 1.06, p<0.001, respectively). Both H1 antihistamines reduce all symptoms of allergic rhinitis, including nasal congestion and the plasmatic level of IL-1β, IL-6, IL-8 and TNF-α, after 4 weeks of treatment. The reduction of cytokine levels was not influenced by patients’ age, sex, duration or severity of rhinitis, or type of sensitization. Levocetirizine has a superior effect compared to desloratadine in reducing the rhinitis symptoms and cytokines’ level. Twenty eight (32.9%) of the patients presented asthma symptoms after 1.5 years. The occurrence of asthma was influenced by house dust sensitization (OR-14.6; CI 95% 1.8–116.3; p=0.01), but baseline values of cytokines were not predictive factors for its appearance. Conclusion: Levocetirizine and desloratadine as a prolonged therapy reduce plasmatic levels of some pro

    Background Allergic rhinitis, allergic dermatitis, and food allergy are extremely common diseases, especially among children, and are frequently associated to each other and to asthma. Smoking is a potential risk factor for these conditions, but so far, results from individual studies have been conflicting. The objective of this study was to examine the evidence for an association between active smoking (AS) or passive exposure to secondhand smoke and allergic conditions. Methods and Findings We retrieved studies published in any language up to June 30th, 2013 by systematically searching Medline, Embase, the five regional bibliographic databases of the World Health Organization, and ISI-Proceedings databases, by manually examining the references of the original articles and reviews retrieved, and by establishing personal contact with clinical researchers. We included cohort, case-control, and cross-sectional studies reporting odds ratio (OR) or relative risk (RR) estimates and confidence intervals of smoking and allergic conditions, first among the general population and then among children. We retrieved 97 studies on allergic rhinitis, 91 on allergic dermatitis, and eight on food allergy published in 139 different articles. When all studies were analyzed together (showing random effects model results and pooled ORs expressed as RR), allergic rhinitis was not associated with active smoking (pooled RR, 1.02 [95% CI 0.92–1.15]), but was associated with passive smoking (pooled RR 1.10 [95% CI 1.06–1.15]). Allergic dermatitis was associated with both active (pooled RR, 1.21 [95% CI 1.14–1.29]) and passive smoking (pooled RR, 1.07 [95% CI 1.03–1.12]). In children and adolescent, allergic rhinitis was associated with active (pooled RR, 1.40 (95% CI 1.24–1.59) and passive smoking (pooled RR, 1.09 [95% CI 1.04–1.14]). Allergic dermatitis was associated with active (pooled RR, 1.36 [95% CI 1.17–1.46]) and passive smoking (pooled RR, 1.06 [95% CI 1.01–1

    Background Past evidence has suggested a role of artificial sweeteners in allergic disease; yet, the evidence has been inconsistent and unclear. Objective To examine relation of intake of artificially-sweetened beverages during pregnancy with child asthma and allergic rhinitis at 18 months and 7 years. Methods We analyzed data from 60,466 women enrolled during pregnancy in the prospective longitudinal Danish National Birth Cohort between 1996 and 2003. At the 25th week of gestation we administered a validated Food Frequency Questionnaire which asked in detail about intake of artificially-sweetened soft drinks. At 18 months, we evaluated child asthma using interview data. We also assessed asthma and allergic rhinitis through a questionnaire at age 7 and by using national registries. Current asthma was defined as self-reported asthma diagnosis and wheeze in the past 12 months. We examined the relation between intake of artificially-sweetened soft drinks and child allergic disease outcomes and present here odds ratios with 95% CI comparing daily vs. no intake. Results At 18 months, we found that mothers who consumed more artificially-sweetened non-carbonated soft drinks were 1.23 (95% CI: 1.13, 1.33) times more likely to report a child asthma diagnosis compared to non-consumers. Similar results were found for child wheeze. Consumers of artificially-sweetened carbonated drinks were more likely to have a child asthma diagnosis in the patient (1.30, 95% CI: 1.01, 1.66) and medication (1.13, 95% CI: 0.98, 1.29) registry, as well as self-reported allergic rhinitis (1.31, 95% CI: 0.98, 1.74) during the first 7 years of follow-up. We found no associations for sugar-sweetened soft drinks. Conclusion Carbonated artificially-sweetened soft drinks were associated with registry-based asthma and self-reported allergic rhinitis, while early childhood outcomes were related to non-carbonated soft drinks. These results suggest that consumption of artificially-sweetened soft drinks

    Acupuncture point application therapies, including San-Fu-Tie and San-Fu-Jiu, have been widely employed to treat diseases with attacks in winter during dog days in China. The therapies combine Chinese herbal medicine and acupuncture points with the nature. However, the previous studies were reported to be unsystematic and incomplete. To develop a more comprehensive understanding of the effects of acupuncture point application therapies on allergic rhinitis and asthma, a systematic review of the literature up to 2015 was conducted. After filtering, eighteen randomized controlled trials (RCTs) involving 1,785 subjects were included. This systematic and narrative review shows that acupuncture point application therapies have been extensively applied in the treatment of allergic rhinitis and asthma with advantages of favorable treatment effect, convenient operation, receiving patients' good acceptability and compliance, and few side effects. Meanwhile, the study elaborated the operating process of San-Fu-Tie and San-Fu-Jiu in detail. The review may provide a reference for clinical application in future. However, the efficacy, safety, and mechanisms of San-Fu-Tie and San-Fu-Jiu in treating the above diseases need to be validated by more well-designed and fully powered RCTs in a larger population of patients.

    Novel strategies are evaluated for management of allergic rhinitis and asthma in patients co-afflicted with both disorders. It is hypothesized that the platelet activating factor receptor antagonist ginkgolide B (GB) and the carotenoid antioxidant astaxanthin (ASX) interact with antihistamines cetirizine dihydrochloride (CTZ) and azelastine (AZE) to potentiate their ability to downregulate potentially pathological immune activation. Peripheral blood mononuclear cells from asthmatics and healthy subjects, cultured 24 hours with 50 μg/ml phytohemaglutinin (PHA) or PHA plus each drug are analyzed by flow cytometry for expression of CD25+ or HLA-DR+ by CD3+ (T cells). Results are reported as stimulation indices for CD3+CD25+ (SICD3+CD25+) and CD3+HLA-DR+ (SICD3+HLADR+) cells in cultures treated with PHA alone, versus cultures treated with both PHA and drugs. Optimal suppression of activated cells was observed in cultures stimulated with ASX 10-6 M + CTZ 10-6 M (SICD3+CD25+, p = 0.016; SICD3+HLADR, p = 0.012); ASX 10-6 M + AZE 10-6 M (SICD3+CD25+, p = 0.012; SICD3+HLADR, p = 0.015); GB 10-6 M + CTZ 10-6 M (SICD3+CD25+, p = 0.024, SICD3+HLADR+, p = 0.019). Results demonstrate improved activity of antihistamines by 2 phytochemicals, suggesting dosing strategies for animal trials of ASX- or GB-augmented formulations for seasonal allergic rhinitis and asthma.

    Orai1 is the key subunit of the Ca2+-release-activated Ca2+ channel. Our previous report has demonstrated that Orai1 expression in the airway was upregulated in the ovalbumin (OVA)-induced allergic rhinitis (AR) mouse models. To observe whether inhibition of Orai1 expression in the airway could suppress symptoms in a murine model of AR and to assess the impacts of this inhibition on the responses of local and systemic immunocytes, we administered recombinant lentivirus vectors that encoded shRNA against ORAI1 (lenti-ORAI1) into the nostrils of OVA-sensitized mice before the challenges, and analyzed its effect on allergic responses, as compared with the unsensitized mice and untreated AR mice. Administration of lenti-ORAI1 into the nasal cavity successfully infected cells in the epithelial layer of the nasal mucosa, and significantly decreased the frequencies of sneezing and nasal rubbing of the mice. Protein levels of leukotriene C4, OVA-specific IgE, and IL-4 in the nasal lavage fluid and serum and eosinophil cation protein in the serum were also significantly reduced by lenti-ORAI1, as were the mRNA levels of these factors in the nasal mucosa and spleen. These data suggested that administration of lenti-ORAI1 into the nasal cavity effectively decreased Orai1 expression in the nasal mucosa, alleviated AR symptoms, and partially inhibited the hyperresponsiveness of the local and systemic immune cells including T cells, B cells, mast cells and eosinophils that are involved in the pathogenesis of AR.

    In the present study, the therapeutic effect and underlying mechanism of α-pinene (α-PN) in the ovalbumin (OVA)-sensitized allergic rhinitis (AR) model were investigated. Our results showed that pretreatment with α-PN caused a decrease in clinical symptoms, including a decrease in the number of nasal, eye, and ear rubs, and spleen weight in the OVA-sensitized mice. The level of interleukin (IL)-4 was decreased on the spleen tissue of α-PN treated mice. Pretreatment with α-PN significantly decreased levels of nasal immunoglobulin E. Protein levels of tumor necrosis factor-α, intercellular adhesion molecule-1, and macrophage inflammatory protein-2 were decreased by the administration of α-PN in the nasal mucosa of the OVA-sensitized mice. The increased numbers of eosinophils and mast cells infiltrating the nasal mucosal tissue of mice with AR were decreased following oral administration of α-PN. Post-treatment with α-PN 1h after OVA challenge also resulted in a significant reduction of clinical symptoms and IgE levels. In addition, the expression and phosphorylation of receptor-interacting protein 2 (RIP2) and IκB kinase (IKK)-β and activation of nuclear factor-κB (NF-κB), and caspase-1 were all increased in the activated human mast cell line, HMC-1 cells, however, increased activations of RIP2, IKK-β, NF-κB, and caspase-1 were inhibited by treatment with α-PN. Taken together, we suggest that α-PN is a promising anti-allergic agent and may be useful in the clinical management of AR.

    A need exists for safe, effective therapy for the relief of the symptoms of allergic rhinitis (AR) that also consistently relieves nasal congestion, the most common and bothersome symptom. This study was performed to assess efficacy and safety of a once-daily tablet containing 10 mg of loratadine, an antihistamine, and 10 mg of montelukast, a leukotriene antagonist (SCH 445761) versus placebo and pseudoephedrine (PSE; 240 mg once-daily formulation; active comparator). In a multicenter, parallel-group, double-blind, double-dummy, randomized study, 1095 subjects with documented history of seasonal AR and positive skin-prick test to a prevailing aeroallergen were treated for 15 days with fixed-dose combination loratadine/montelukast (L/M), PSE, or placebo. After randomization, subjects rated severity of nasal congestion and measured peak nasal inspiratory flow (PNIF) rate in the morning and evening. The change in quality of life from baseline was also assessed. L/M and PSE were significantly more effective than placebo in alleviating nighttime and daytime nasal congestion and improving PNIF rate, an objective measure of nasal obstruction. There were no significant differences between L/M and PSE for any efficacy analysis including improvement in the quality of life. Subjects treated with L/M experienced a similar incidence of total adverse events versus placebo and a lower incidence of total adverse events (including dizziness, insomnia, jitteriness, nausea, and dry mouth) versus PSE. Nasal decongestant activity of L/M was significantly higher than that of placebo and similar to that of PSE in symptomatic AR subjects. L/M showed a safety profile similar to placebo and was better tolerated than PSE. Thus, L/M offers a safe and efficacious alternative to PSE for the treatment of nasal congestion associated with AR.

    Allergic rhinitis has a very high burden regarding both direct and indirect costs. This makes essential in the management of AR to reduce the clinical severity of the disease and thus to lessen its costs. This particularly concerns allergen immunotherapy (AIT), that, based on its immunological action on the causes of allergy, extends its benefit also after discontinuation of the treatment. From the pharmacoeconomic point of view, any treatment must be evaluated according to its cost-effectiveness, that is, the ratio between the cost of the intervention and its effect. A favorable cost-benefit ratio for AIT was defined, starting from the first studies in the 1990s on subcutaneous immunotherapy (SCIT) in AR patients, that highlighted a clear advantage on costs over the treatment with symptomatic drugs. Such outcome was confirmed also for sublingual immunotherapy (SLIT), that has also the advantage on SCIT to be free of the cost of the injections. Here we review the available literature on pharmacoeconomic data for SLIT with the 5-grass pollen tablets.

    Background Treatment of allergic rhinitis (AR) consistent with consensus guidelines is reported to result in better patient outcomes. However, physicians may manage patients independently of guidelines. Asian data on physician perspectives regarding AR diagnosis and management is limited. Objective The study objective is to assess attitudes and practices on AR of Filipino specialists and generalists. Methods A cross sectional survey of 100 specialists and 100 generalists was conducted from November 2014 to January 2015. A previously validated and pilot tested questionnaire was administered via structured face to face interviews. Results Specialists reported greater adequate knowledge of AR (specialists, 58%; generalists, 39%) and adherence to guidelines (specialists, 84%; generalists, 54%). Diagnostic tests were not routinely used (specialists, 81%; generalists, 92%). Monotherapy, specifically antihistamines, was preferred for mild AR. For moderate-severe AR, preference for monotherapy versus combination therapy (specialists, 49% vs. 51%; generalists, 44% vs. 56%) was similar. Both groups preferred intranasal corticosteroid spray (INCS) for monotherapy and antileukotrienes, antihistamines, INCS for combination therapy. For adjuvant therapy, specialists (82%) preferred nasal irrigation/douche. Primary consideration for choice of therapy was efficacy. Cost was the perceived reason for patients' noncompliance with treatment. Conclusion Despite differences in awareness of and adherence to guidelines, prescribing patterns on management of mild and moderate-severe AR are similar among Filipino specialists and generalists. This can be attributed to a shared perception of efficacy and cost as drivers for therapeutic choices. PMID:26539402

    Introduction. This study was designed to investigate the effects of low level laser therapy (LLLT) on experimental allergic rhinitis (AR) models induced by ovalbumin. Materials and Methods. AR was induced by 1% ovalbumin in mice. Twenty-four mice were divided into 4 groups: normal, control, low, and high dose irradiation. Low and high dose LLLT were irradiated once a day for 7 days. Total IgE, cytokines concentrations (IL-4 and IFN-γ), and thymus and activation regulated chemokine (TARC) were measured. Histological changes in the nasal mucosal tissue by laser irradiation were examined. Results. LLLT significantly inhibited total IgE, IL-4, and TARC expression in ovalbumin-induced mice at low dose irradiation. The protein expression level of IL-4 in spleen was inhibited in low dose irradiation significantly. IL-4 expression in EL-4 cells was inhibited in a dose dependent manner. Histological damages of the epithelium in the nasal septum were improved by laser irradiation with marked improvement at low dose irradiation. Conclusion. These results suggest that LLLT might serve as a new therapeutic tool in the treatment of AR with more effectiveness at low dose irradiation. To determine the optimal dose of laser irradiation and action mechanisms of laser therapy, further studies will be needed. PMID:24319484

    The aim of this study was to determine the prevalence of sensitization to common allergens in children with allergic rhinitis (AR) living in Qingdao, China. We conducted a retrospective analysis for AR cases, who underwent skin prick tests (SPT) in Qingdao. A total of 2841 children with AR qualified for the inclusion criteria (Age 3-5 years: 1500 children; Age 6-12 years: 1341 children). The most common inhaled allergens to which the AR children were sensitive were Dermatophagoides pteronyssinus (69.3%), Dermatophagoides farinae (66.2%) and mould 1 (Penicillium notatum 38.9%); while the corresponding ingested allergens were mussel (39.2%), shrimp (36.3%) and carp (36.5%). The prevalence of sensitization to inhaled allergens and food allergens was higher in children >6 years of age as compared to that in children 3-5 years of age (all p < 0.05). Children >6 years old were more sensitive to dust mite as compared to children 3-5 years old (p < 0.05). Sensitization to dust mite was more common in males than in females (p = 0.05). In this study, Dermatophagoides pteronyssinus and Dermatophagoides farinae were the most common allergens causing AR in children in Qingdao, China. Older children with AR, particularly males, were found to be more sensitive to dust mite.

    Atopic dermatitis (AD) is an inflammatory disease characterized by pruritic skin lesions. The pathogenesis of AD may include disrupted epidermal barrier function, immunodysregulation, and IgE-mediated sensitization to food and environmental allergens. AD is also part of a process called the atopic march, a progression from AD to allergic rhinitis and asthma. This has been supported by multiple cross-sectional and longitudinal studies and experimental data. Research on the mechanisms of AD has been centered on the adaptive immune system with an emphasis on the T-helper 1 (Th1)-Th2 paradigm. Recently, the conceptual focus has largely shifted to include a primary defect in the epithelial barrier as an initial event in AD providing a significant insight into the disease initiation and pointing to a complex secondary interplay of environmental and immunological sequelae with barrier disruption. Further understanding of AD will help the development of more effective treatment for AD and ultimately, preventative algorithms for the atopic march. In this review we highlight recent advances in our understanding of the pathogenesis of AD and the atopic march.

    The objective of this study was to compare the effectiveness of montelukast combined with loratadine once daily to loratadine alone for a 2-week treatment course of allergic rhinitis in a randomized, double-blind placebo controlled trial which enrolled 115 children, 6- 15-years-old. The patients were randomly assigned to receive montelukast and loratadine (treatment group) or placebo and loratadine (control group). The primary outcome was the mean percent change of the total daytime nasal symptom scores (PDTS) and secondary outcomes were the mean percent changes of the nighttime nasal, daytime eye and composite symptom scores (PNTS, PES, PCS), as well as the nasal secretion, turbinate swelling and nasal congestion scores (PNSS, PTSS, PNCS). There were no significant differences in the PDTS of the 2 groups. The change in the night time nasal congestion score (PNTS-congestion) was higher in the treatment group, but not statistically significant (p = 0.077). Only the mean percent change in decreased turbinate swelling was significantly greater in the montelukast and loratadine group than the loratadine alone group (-22 +/- 7 vs. -1 +/- 5, p < 0.05).

    The selection of pharmacotherapy for patients with allergic rhinitis (AR) depends on several factors, including age, prominent symptoms, symptom severity, control of AR, patient preferences, and cost. Allergen exposure and the resulting symptoms vary, and treatment adjustment is required. Clinical decision support systems (CDSSs) might be beneficial for the assessment of disease control. CDSSs should be based on the best evidence and algorithms to aid patients and health care professionals to jointly determine treatment and its step-up or step-down strategy depending on AR control. Contre les MAladies Chroniques pour un VIeillissement Actif en Languedoc-Roussillon (MACVIA-LR [fighting chronic diseases for active and healthy ageing]), one of the reference sites of the European Innovation Partnership on Active and Healthy Ageing, has initiated an allergy sentinel network (the MACVIA-ARIA Sentinel Network). A CDSS is currently being developed to optimize AR control. An algorithm developed by consensus is presented in this article. This algorithm should be confirmed by appropriate trials.

    Nitric oxide (NO) plays an important role in the regulation of upper respiratory function. Patients with untreated allergic rhinitis (AR) have an increased level of NO in the nasal cavity compared to normal individuals. We aimed to investigate serum levels of arginase and NO metabolites nitrite/nitrate in patients with AR during the symptomatic period. The patient and control groups consisted of 14 males and 12 females (mean age: 29, range: 20-40 years), and 10 males and 10 females (mean age: 27, range: 22-38 years), respectively. Nitrite/nitrate levels were 0.98 +/- 0.33 ng/ml in the patients with AR, and 0.78 +/- 0.26 ng/ml in the control group (p = 0.03). Arginase levels were 28.8 +/- 14.1 ng/ml in the patients with AR, and 20.8 +/- 13.5 ng/ml in the control group. The difference between the groups was statistically insignificant (p = 0.24). Our results support the view that NO plays an important role in the pathogenesis of AR, and NO metabolites may be used as a marker for monitoring the disease activity and therapy.

    Purpose Maternal influences contribute to the origin of allergic diseases, but the mechanisms are not clear. The current literature prompted the role of epigenetics in the development of allergic diseases. We sought to investigate the roles of regulatory T (Treg) cells and Forkhead box p3 (Foxp3) DNA methylation in the process of maternal transmission of allergic rhinitis (AR) susceptibility. Methods BALB/c female mice (AR mother) were sensitized by intraperitoneal injection of Dermatophagoides pteronyssinus (Der p) 1 on day 1 and 7. Then they mated with normal male mice on day 8. From day 21 to 28, the female mice were intranasal challenged with Der p 1 continuously. The normal controls were given with normal saline in the same way. On postnatal day 3, Female mice and their offspring were sacrificed to detect their histopathology in nasal mucosae, cytokines in sera of mother and spleen homogenates of offspring, Treg cells count, Foxp3 mRNA expressions, and Foxp3 DNA methylation levels in spleens. Results Compared with the normal controls, neonatal offspring of Der p 1-stimulated female mice (AR offspring) showed the elevation of interleukin (IL)-4 (P<0.01) and IL-17 (P<0.01), the submission of IL-10 (P<0.01) in spleen homogenates. Further, Treg cells count in AR offspring decreased remarkably compared with the normal offspring (P<0.01). Though the difference of Foxp3 DNA methylation level between AR offspring and normal control offspring was not obvious, correlation analysis demonstrated that there was significantly positive correlation between Foxp3 DNA methylation level of mother and that of offspring (r=0.803, P<0.01). Conclusions Under the influence of Maternal AR, their neonatal offspring develop into T-helper type 2 (Th2) dominant immune state, which is closely associated with the recession of Treg cells. Foxp3 DNA methylation may be a mechanism responsible for that maternal effect but still need more studies to ensure. PMID:28102058

    This is the first U.S.-based study to compare efficacy and safety of desloratadine with fexofenadine in subjects with symptomatic seasonal allergic rhinitis (SAR). In this double-blind study, subjects were randomized to desloratadine, 5 mg (n = 290),fexofenadine, 180 mg (n = 288), or placebo (n = 144) once daily for 15 days. Primary end point was mean change from baseline to study end in morning instantaneous total symptom score (AM NOW TSS) excluding congestion. Secondary measures included change from baseline in the morning/evening reflective TSS (AM/PM PRIOR TSS) excluding congestion, AM NOW individual symptom score (AM NOW ISS) including congestion, and the AM/PM PRIOR ISS including congestion. Subjects self-evaluated their symptoms on a five-point scale. Mean AM NOW TSSs were significantly reduced from baseline at day 15 with desloratadine (p = 0.006) and fexofenadine (p = 0.024) versus placebo. Desloratadine and fexofenadine were not statistically different (p = 0.491); the upper limit of the 95% CI for desloratadine to fexofenadine (0.259) was within the prespecified noninferiority margin of 0.7 U. Decrease in mean AM/PM PRIOR TSS excluding congestion was comparable between desloratadine and fexofenadine (p = 0.405; CI = 0.221) but was significantly greater with both active treatments versus placebo (desloratadine, p < 0.001;fexofenadine, p = 0.003). Desloratadine and fexofenadine provided greater reduction in the AM NOW ISS and AM/PM PRIOR ISS (both including congestion) versus placebo; reductions were comparable between active treatments. All treatments were well tolerated. Desloratadine, 5 mg, and fexofenadine, 180 mg, provide comparable efficacy and tolerability in the treatment of SAR. Both treatments are significantly more effective than placebo.

  12. The effects of two Chinese herbal medicinal formulae vs. placebo controls for treatment of allergic rhinitis: a randomised controlled trial

    2014-01-01

    Background Allergic rhinitis is a chronic illness, affecting 10 to 40% of the worldwide population. Chinese herbal medicines, the treatment of allergic rhinitis, adopted thousands of years in ancient China, has recently raised much attention among researchers globally. This study evaluates the effects of two Chinese herbal formulae [Cure-allergic-rhinitis Syrup (CS) and Yu-ping-feng San (YS)] in treating undergraduate nursing students with allergic rhinitis over a 3-month follow-up, when compared to a placebo control group. Methods A double-blind, randomised controlled trial with repeated-measures, three-parallel-groups design was conducted in a random sample of 249 participants recruited from one university in Hong Kong. After baseline measurements, participants were randomly assigned to CS, YS, or placebo groups (n = 83 per group). The main outcomes, including symptom severity, quality of life, and body constitution, were measured with self-administered questionnaires at baseline and immediately, 1 and 3 months after the 4-week interventions. Results 240 participants completed the trial, with 9 (3.6%) drop-outs. The results of Generalised Estimating Equations test followed by pairwise contrasts tests indicated that the participants who received CS showed significantly greater reduction of symptoms (mean difference of CS vs. placebo = 26.13–34.55, P <0.0005) and improvements in quality of life (mean difference of CS vs. placebo = 12.81–16.76, P <0.001), and body constitution in ‘Qi-deficiency’, ‘Yang-deficiency’, and ‘Inherited Special’ (mean difference of CS vs. placebo = 7.05–8.12, 7.56–8.92, and 4.48–8.10, P = 0.01– < 0.0005, 0.001–0.004, and 0.01– < 0.0005, accordingly, at three post-tests). The participants who received YS also indicated significant greater improvements in symptom severity, quality of life, and a few patterns of body constitution when compared to the placebo group. However, its effects

    Background: Group 2 innate lymphoid cells (ILC2s) are regarded as a novel population of lineage-negative cells that induce innate Type 2 responses by producing the critical Th2-type cytokines interleukin (IL)-5 and IL-13. ILC2s as key players in the development of allergic rhinitis (AR) have been proved, however, the effect of subcutaneous immunotherapy (SCIT) with dermatophagoides pteronyssinus extract (Der p-SCIT) on ILC2s in AR patients is not clear. This study aimed to investigate the response of ILC2s of peripheral blood in house dust mites (HDM)-sensitized Chinese patients with AR who received SCIT with Der P extract. Methods: Seven healthy controls without symptoms of AR who had negative reactions to any of the allergens from skin-prick testing, nine patients diagnosed with persistent AR according to the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines, and 24 AR patients who received Der p-SCIT for 1.0–3.5 years were recruited for the study. ILC2s in the peripheral blood were evaluated using flow cytometry. The severity of their symptoms of all participants was rated based on the Total 5 symptom score. Results: Among 40 participants, 9 AR patients were assigned to the untreated group, 24 AR patients receiving Der p-SCIT were assigned to the immunotherapy group, and 7 healthy controls without symptoms of AR were assigned to healthy control group. The mean Total 5 symptom score of immunotherapy group was significantly lower than that of untreated group (4.3 ± 1.4 vs. 10.1 ± 2.5, P < 0.001). Similarly, the levels of ILC2s in the peripheral blood of immunotherapy group were significantly reduced compared with that in untreated group (P < 0.001), but were not significantly different from healthy controls (P = 0.775). Further subgroup analysis based on the duration of SCIT therapy (1.0–2.0 years [SCIT1-2], 2.0–3.0 years [SCIT2-3], and 3.0–3.5 years [SCIT3-3.5]) showed that the percentage of ILC2s was not significantly different between SCIT1

    Allergic rhinitis (AR), a chronic inflammatory disease of the upper airway, is one of the most common chronic diseases in the United States and is estimated to affect up to 60 million people. Pediatric Allergies in America is the largest and most comprehensive survey to date of pediatric patients and parents of patients with allergy, as well as health care providers (HCPs), regarding AR in children and its treatment. The goals of the survey were to determine the prevalence of AR in the US pediatric population and to collect information on what effect the condition has on patients in terms of symptom burden, quality of life, productivity, disease management, and pharmacologic treatment. This national survey screened 35,757 households to identify 500 children with HCP-diagnosed nasal allergies and 504 children without nasal allergies who were between the ages of 4 and 17 years. Parents of young children, as well as children 10 to 17 years of age, were questioned about the condition and its treatment. In parallel, 501 HCPs were interviewed. This survey has captured previously unavailable data on the prevalence of nasal allergies and their most common and most bothersome symptoms, on the effect of nasal allergies on the quality of life of children, and on medication use, including both over-the-counter and prescription medications, and has identified factors affecting satisfaction with treatment. The Pediatric Allergies in America survey also identifies distinct areas for improvement in the management of AR in children. In fact, based on the results of this survey, it appears that HCPs overestimate patients' and parents' satisfaction with disease management and the benefit of medications used for the treatment of nasal allergies in children. Findings from this national survey have identified important challenges to the management of AR, suggesting that its burden on children in the United States has been significantly underestimated.

    This study is aimed to investigate the effectiveness of 4 allergic rhinitis (AR) drugs (loratadine, cetirizine, montelukast, and desloratadine) in reducing functional problems in patients, as indicated by rhinoconjunctivitis quality of life questionnaire scores. After an exhaustive search of electronic databases containing published scientific literature, high-quality randomized controlled trials relevant to our study were selected based on a stringent predefined inclusion and exclusion criteria. Statistical analyses were conducted using STATA 12.0 and comprehensive meta-analysis (CMA 2.0) software. The literature search broadly identified 386 studies, and after a multistep screening and elimination process, a total of 13 randomized controlled trials contributed to this network meta-analysis. These 13 high-quality studies contained a combined total of 6867 patients with AR on 4 different medications. The results of network meta-analysis revealed that, compared with placebo, all 4 mediations treated AR effectively [cetirizine: mean: -0.62, 95% confidence intervals (95% CI) = -0.90 to -0.34, P < 0.001; loratadine: mean: -0.32, 95% CI = -0.55 to -0.097, P = 0.005; montelukast: mean: -0.28, 95% CI = -0.54 to -0.023, P = 0.033; desloratadine: mean: -0.39, 95% CI = -0.60 to -0.18, P < 0.001]. A comparison of surface under the cumulative ranking curve values of these 4 interventions clearly showed that cetirizine is the most optimal medication for AR treatment. In conclusion, this network meta-analysis provides the first evidence that cetirizine is the most efficacious treatment for AR compared with loratadine, montelukast, and desloratadine, significantly reducing the functional problems in patients with AR.

    Aims and Objectives: Environmental pollens are known to cause exacerbation of symptoms of patients with allergic rhinitis (AR) and asthma. During pollen months, number of patients visiting hospital has been shown to increase in some studies. However, in India, such studies are lacking. Therefore, we aimed to study pollen counts and to find its correlation with number of new patients attending Asthma Bhawan for 2 years. Materials and Methods: Aerobiological sampling was done using Burkard 24 h spore trap system. The site selected for the entrapment of the air spore was the building of Asthma Bhawan situated at Vidhyadhar Nagar, Jaipur. New patients coming with problems of respiratory allergy such as AR or asthma were recruited in the study. Skin prick tests (SPTs) were carried out after obtaining consent in these patients. Monthly pollen counts of trees, weeds and grasses were correlated with the number of new patients. Pollen calendar was prepared for 2 years. Results: Average annual pollen count during 2011 and 2012 were 14,460.5. In the analysis, 37 types of species or families were identified. Pollen count showed two seasonal peaks during March–April and from August to October. January and June showed the lowest pollen counts in 2 years. Average monthly count of grass pollens showed significant correlation with number of new patients (r = 0.59). However, monthly pollen count of trees and weeds did not correlate. The correlation of the pollen count of individual pollen with the SPT positivity to that pollen showed significant correlation with Chenopodium album only. Conclusions: It can be concluded that there were two peaks of pollen count in a year during March–April and August–October. Average monthly pollen counts of grass were significantly correlated with the number of hospital visits of new patients. PMID:28360459

    Background Glucocorticoids (GCs) play a key role in the treatment of seasonal allergic rhinitis (SAR). However, some patients show a low response to GC treatment. We hypothesized that proteins that correlated to discrimination between symptomatic high and low responders (HR and LR) to GC treatment might be regulated by GCs and therefore suitable as biomarkers for GC treatment. Methodology/Principal Findings We identified 953 nasal fluid proteins in symptomatic HR and LR with a LC MS/MS based-quantitative proteomics analysis and performed multivariate analysis to identify a combination of proteins that best separated symptomatic HR and LR. Pathway analysis showed that those proteins were most enriched in the acute phase response pathway. We prioritized candidate biomarkers for GC treatment based on the multivariate and pathway analysis. Next, we tested if those candidate biomarkers differed before and after GC treatment in nasal fluids from 40 patients with SAR using ELISA. Several proteins including ORM (P<0.0001), APOH (P<0.0001), FGA (P<0.01), CTSD (P<0.05) and SERPINB3 (P<0.05) differed significantly before and after GC treatment. Particularly, ORM (P<0.01), FGA (P<0.05) and APOH (P<0.01) that belonged to the acute phase response pathway decreased significantly in HR but not LR before and after GC treatment. Conclusions/Significance We identified several novel biomarkers for GC treatment response in SAR with combined proteomics, multivariate and pathway analysis. The analytical principles may be generally applicable to identify biomarkers in clinical studies of complex diseases. PMID:21887273

    The aim of this study was to evaluate the possible favorable effect of desloratadine-montelukast combination on salivary glands (SG) function in patients with allergic rhinitis (AR) using SG scintigraphy. The study population consisted of 64 patients with AR and 28 healthy controls: 14 males and 14 females, with mean age 32.3±8.6 years. The patients were divided into two groups: the untreated patients group of 32 patients, 16 males and 16 females, mean age 28.5±5.4 years and the treated group, who received the standard clinically recommended oral dose of montelukast 10mg/d and desloratadine 5mg/d for 6 weeks. This group consisted of 32 patients, 16 males and 16 females, mean age 38.3±8.4 years. All patients and healthy controls underwent SG scintigraphy. After the intravenous injection of technetium-99m pertechnetate, ((99m)Tc-P), dynamic SG scintigraphy was performed for 25min. Using the time-activity curves, the following glandular function parameters were calculated for the parotid and the submandibular SG: uptake ratio, maximum accumulation and ejection fraction. Results showed SG hypofunction. All functional parameters obtained for the untreated patients and for the desloratadine-montelukast treated patients were significantly lower than those in healthy controls (P<0.05). There was no statistically significant difference between treated and untreated patients (P>0.05). In conclusion, our study showed that hypofunction of SG was present in all patients with AR. This hypofunction, as tested by semi-quantitative SG scintigraphy, and also the quality of life did not improve after treatment with montelukast and desloratadine.

    Allergic rhinitis (AR; also nasal allergies or "hay fever") is a chronic upper airway inflammatory disease that affects ∼60 million adults and children in the United States. The duration and severity of AR symptoms contribute to a substantial burden on patients' quality of life (QoL), sleep, work productivity, and activity. This study was designed to examine symptoms, QoL, productivity, comorbidities, disease management, and pharmacologic treatment of AR in United States and ex-U.S. sufferers. Allergies in America was a comprehensive telephone-based survey of 2500 adults with AR. These data are compared and contrasted with findings from the Pediatric Allergies in America, Allergies in Latin America, and Allergies in Asia-Pacific telephone surveys. The prevalence of physician-diagnosed AR was 14% in U.S. adults, 7% in Latin America adults, and 9% in Asia-Pacific adults. Nasal congestion is the most common and bothersome symptom for adults. Approximately two-thirds of adults rely on medication to relieve intolerable AR symptoms. Incomplete relief, slow onset, <24-hour relief, and reduced efficacy with sustained use were commonly reported with AR medications, including intranasal corticosteroids. One in seven U.S. adults reported achieving little to no relief with AR medications. Bothersome adverse effects of AR medications included drowsiness, a drying feeling, medication dripping down the throat, and bad taste. Perception of inadequate efficacy was the leading cause of medication discontinuation or change and contributed to treatment dissatisfaction. These findings support the assertion that AR burden has been substantially underestimated and identify several important challenges to successful management of AR.

    The objective of the study is to assess the efficacy of the nonsedating antihistamine, desloratadine, in the treatment of allergic rhinitis (AR). A search of MEDLINE, EMBASE, LILACS, and CINAHL databases was undertaken from January, 1966 to May, 2006. Double-blind, randomized, controlled studies of desloratadine in the treatment of AR in adult patients were carried out. The measured outcomes included the total symptoms score, the total nasal symptoms score, nasal airflow, and inflammatory markers (nasal eosinophils, nasal interleukin-4). The analysis included the calculation of standardized mean difference (SMD). A total of 57 studies were analyzed, and 13 randomized, double-blind, controlled trials were included in the meta-analysis. The trials included 3108 subjects who had completed studies involving desloratadine. There was significant heterogeneity among the study results, because of differing study methodologies. Desloratadine was associated with significant reductions in total symptoms scores (SMD -1.63; 95% CI -2.75 to -0.51; P = 0.004) and total nasal symptoms score (SMD -0.66; 95% CI -0.91 to -0.42; P < 0.001), when compared with placebo. Analysis of objective data on nasal blockage demonstrated a significant improvement in nasal airflow with desloratadine, when compared with placebo (SMD 0.32; 95% CI 0.10 to 0.55; P = 0.005). A benefit favoring desloratadine over placebo in terms of nasal eosinophil levels was also noted in the analysis. This meta-analysis confirms the reduction of AR symptoms and improvement in nasal airflow seen in individual studies of desloratadine. Objective improvements in nasal airflow, total symptoms, and total nasal symptoms seen with desloratadine are supported by Ia evidence.

    Allergic rhinitis (AR) symptoms can impart emotional, quality of life (QOL), and work productivity burdens, especially in persistent AR (PER). Desloratadine, an H1-receptor antagonist, has been shown to be effective against nasal and nonnasal AR symptoms and to improve QOL. Exploratory analyses were conducted to evaluate whether desloratadine-mediated symptom improvement correlated with improvements in QOL and productivity. The Aerius Control: Clinical and Evaluative Profile of Treatment 2 (NCT00405964) study was a 12-week, multinational, randomized, placebo-controlled prospective study of once-daily desloratadine at 5 mg in subjects with moderate-to-severe PER. Assessments included twice-daily symptom severity ratings (0 = none to 3 = severe; total and individual symptoms), sleep interference (morning [A.M.]), interference with activities of daily living (ADL; evening [P.M.]), the Rhinoconjunctivitis Quality of Life Questionnaire-Standardized version (baseline and days 29 and 85), and the Work Productivity and Activity Impairment-Allergy-Specific questionnaire (baseline and weekly). Pearson product-moment correlation statistics (r) were determined to assess correlations between symptom score improvements and QOL factors. All desloratadine-treated patients (n = 360) were included in this exploratory analysis. In the desloratadine-treated patients, all correlations tested were positive (all p < 0.0001). The highest coefficients were seen for the correlations between A.M./P.M. PRIOR total five-symptom score and interference with ADL (r = 0.72) and between A.M. NOW congestion and ADL interference (r = 0.69). Continuous daily treatment of moderate-to-severe PER with desloratadine at 5 mg/day significantly improved symptoms, which correlated positively, albeit moderately, with QOL benefits and reversal of functional impairments caused by PER.

    Although we previously demonstrated the contribution of the DP1receptor in nasal obstruction using animals sensitized with ovalbumin in the presence of adjuvant, the contribution of the DP1receptor in sneezing is unclear. Here, we developed a mouse model of Japanese cedar (JC:Cryptomeria japonica) pollinosis to evaluate the symptoms of sneezing. To achieve this, we used JC pollen crude extract in the absence of adjuvant to sensitize mice to develop a model closer to the pathophysiology of human JC pollinosis. The immunologic and pharmacologic features of this model are highly similar to those observed in JC pollinosis in humans. Using this model, we found that DP1receptor antagonists suppressed JC pollen extract-induced sneezing and that a DP1receptor agonist induced sneezing. Moreover, JC pollen extract-induced sneezing was diminished in DP1receptor knockout mice. In conclusion, we developed a novel mouse model of allergic rhinitis that closely mimics human JC pollinosis. A strong contribution of DP1receptor signaling to sneezing was demonstrated using this model, suggesting that DP1receptor antagonists could suppress sneezing and nasal obstruction, and therefore these agents could be a new therapeutic option for allergic rhinitis.

    Object: To determine the potential of bone marrow-derived mesenchymal stem cells (BMSCs) for immunomodulatory mechanism in mice model of allergic rhinitis (AR). Methods: BMSCs were isolated and the surface markers and stemness were analyzed. The effect of BMSCs was evaluated in BALB/c mice that were randomly divided into three groups (control group, ovalbumin (OVA) group, OVA+BMSCs group). BMSCs were administered intravenously to OVA sensitized mice on days 1, 7, 14 and 21, and subsequent OVA challenge was conducted daily from days 22 to 35. Several parameters of allergic inflammation were assessed. Results: Mesenchymal stem cells can be successfully isolated from bone marrow of mice. Intravenous injection of BMSCs significantly reduced allergic symptoms, eosinophil infiltration, OVA-specific immunoglobulin E (IgE), T-helper 2 (Th2) cytokine profile (interleukin (IL)-4, IL-5 and IL-13) and regulatory cytokines (IL-10). In addition, level of Th1 (IFN-γ) was significantly increased. Conclusion: Administration of BMSCs effectively reduced allergic symptoms and inflammatory parameters in the mice model of AR. BMSCs treatment is potentially an alternative therapeutic modality in AR. PMID:28078033

  4. Reasons for prescribing second generation antihistamines to treat allergic rhinitis in real-life conditions and patient response

    2014-01-01

    Background Second generation H1 antihistamines (H1A) are currently recommended as first choice medications for allergic rhinitis and rhinoconjunctivitis. However, little is known about what influences the choice of prescription of one second generation (H1A) as opposed to another in real-life conditions. Objective The aim of the study was to identify the main criteria determining the choice of a second generation H1A by allergy specialists in mainland France. Methods Consecutive patients suffering from allergic rhinitis or rhinoconjunctivitis were included and followed prospectively for 30 days from the prescription of a second generation H1A in monotherapy. Patients were asked to fill in auto-questionnaires at baseline, daily during the first 10 days of the new treatment, and at the end of follow-up. Data on efficacy, tolerance, safety, rate and type of response to treatment, as well as patient satisfaction were recorded and analyzed. Results 1,080 patients were included between March 2011 and October 2012, mostly suffering from moderate to severe rhinitis (82.0%). The most frequently cited reason for choosing a specific H1A was the expected efficacy (85.3%). The mean time to nasal and ocular recovery was 6 days and 78.2% of patients responded to treatment within this interval. The presence of conjunctivitis was significantly associated with a more rapid response. At the end of follow-up, the satisfaction rate was higher for patients who were switched from a previous treatment (87.5%), compared to those receiving their first treatment (78.8%). Conclusion and clinical relevance The main reason for choosing a specific second generation H1A was its expected efficacy. Concomitant conjunctivitis is associated with a more rapid response to treatment. Symptom recovery necessitates a mean of 6 days. PMID:24944561

    Objective To test the hypothesis that homoeopathy is a placebo by examining its effect in patients with allergic rhinitis and so contest the evidence from three previous trials in this series. Design Randomised, double blind, placebo controlled, parallel group, multicentre study. Setting Four general practices and a hospital ear, nose, and throat outpatient department. Participants 51 patients with perennial allergic rhinitis. Intervention Random assignment to an oral 30c homoeopathic preparation of principal inhalant allergen or to placebo. Main outcome measures Changes from baseline in nasal inspiratory peak flow and symptom visual analogue scale score over third and fourth weeks after randomisation. Results Fifty patients completed the study. The homoeopathy group had a significant objective improvement in nasal airflow compared with the placebo group (mean difference 19.8 l/min, 95% confidence interval 10.4 to 29.1, P=0.0001). Both groups reported improvement in symptoms, with patients taking homoeopathy reporting more improvement in all but one of the centres, which had more patients with aggravations. On average no significant difference between the groups was seen on visual analogue scale scores. Initial aggravations of rhinitis symptoms were more common with homoeopathy than placebo (7 (30%) v 2 (7%), P=0.04). Addition of these results to those of three previous trials (n=253) showed a mean symptom reduction on visual analogue scores of 28% (10.9 mm) for homoeopathy compared with 3% (1.1 mm) for placebo (95% confidence interval 4.2 to 15.4, P=0.0007). Conclusion The objective results reinforce earlier evidence that homoeopathic dilutions differ from placebo. PMID:10948025

    The objective of this study is to evaluate the effect of exhaled CO (eCO) on the development of asthma and allergic rhinitis (AR) by means of reviewing published literature. The literatures published between January 1997 and December 2008 from the US National Library of Medicine (NLM) Database were obtained according to inclusion criteria. Meta-analysis of randomized controlled trials (RCTs) was performed. CO levels of asthma and AR patients were compared with that of normal controls. HO-1(heme oxygenase-1) expression and effect of corticosteroids on eCO levels were also analyzed. Fifteen studies concerning asthma and four studies concerning AR were included in this analysis. Heterogeneity from different studies was evident (P < 0.0001), so a random-effects model was preferred. The meta-analysis revealed that asthmatic patients had significantly higher levels of eCO compared to normal controls. There was significant difference between asthma and control groups in terms of eCO (combined weighted mean difference (WMD) 1.33 (95% confidence interval 0.72 to 1.95), P < 0.0001), and no significant difference between AR and control (combined WMD 0.93 (95% confidence interval -0.54 to 2.40), P = 0.22). HO-1 expression were also reviewed, asthma group produced greater expression of HO-1 than control group with significant difference (combined standardized mean difference (SMD) 2.98 (95% confidence interval 1.13 to 4.84), P = 0.002). After corticosteroid therapy, significantly different levels of eCO were produced after corticosteroid therapy than did asthma group (combined WMD -1.23 (95% confidence interval -2.43 to -0.03), P = 0.04). The analysis reveals that eCO levels were significantly raised in asthma and it may attribute to high expression of HO-1, but there were no significantly high eCO levels between AR and control groups. Due to sensitivity to corticosteroid inhibition, eCO may be used as a practical marker to detect and monitor exacerbation of asthma.

    Rhinitis is a multifactorial disease characterized by symptoms of sneezing, rhinorrhea, postnasal drip, and nasal congestion. Non-allergic rhinitis is characterized by rhinitis symptoms without systemic sensitization of infectious etiology. Based on endotypes, we can categorize non-allergic rhinitis into an inflammatory endotype with usually eosinophilic inflammation encompassing at least NARES and LAR and part of the drug induced rhinitis (e.g., aspirin intolerance) and a neurogenic endotype encompassing idiopathic rhinitis, gustatory rhinitis, and rhinitis of the elderly. Patients with idiopathic rhinitis have a higher baseline TRPV1 expression in the nasal mucosa than healthy controls. Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is the active component of chili peppers, plants of the genus Capsicum. Capsaicin is unique among naturally occurring irritant compounds because the initial neuronal excitation evoked by it is followed by a long-lasting refractory period, during which the previously excited neurons are no longer responsive to a broad range of stimuli. Patients with idiopathic rhinitis benefit from intranasal treatment with capsaicin. Expression of TRPV1 is reduced in patients with idiopathic rhinitis after capsaicin treatment. Recently, in a Cochrane review, the effectiveness of capsaicin in the management of idiopathic rhinitis was evaluated and the authors concluded that given that many other options do not work well in non-allergic rhinitis, capsaicin is a reasonable option to try under physician supervision. Capsaicin has not been shown to be effective in allergic rhinitis nor in other forms of non-allergic rhinitis like the inflammatory endotypes or other neurogenic endotypes like rhinitis of the elderly or smoking induced rhinitis.

    The effect of oxidant inhalation on allergic illness is of interest because allergic patients often report increased respiratory symptoms during episodes of poor air quality, and epidemiologic studies demonstrate an association between increased levels of the air pollutant ozone and exacerbations of asthma. The purpose of this study was to characterize the upper respiratory response to ozone inhalation in asymptomatic, allergic subjects and to determine whether ozone pre-exposure increased the acute response to nasal challenge with antigen in these subjects. A group of 12 asymptomatic subjects with a history of allergic rhinitis were exposed in a randomized, cross-over design, at rest, on each of 2 days, separated by 2 wk, to 4 h of clean air or 0.5 ppm ozone in an environmental chamber. Following the exposure period, subjects underwent nasal challenge with four doses of antigen (1 to 1,000 PNU ragweed or grass). Symptoms were rated and nasal lavage performed after each dose. Measurement of histamine and albumin concentration and TAME-esterase activity and determination of cell counts and differentials were performed. Exposure to ozone caused significant increases in upper and lower respiratory symptoms, a mixed inflammatory cell influx with a sevenfold increase in naval lavage neutrophils, a 20-fold increase in eosinophils, and a tenfold increase in mononuclear cells, as well as an apparent sloughing of epithelial cells. There was a significant increase in nasal lavage albumin concentration on the ozone exposure day and a small increase in nasal lavage histamine concentration on both the ozone and clean air exposure days. TAME-esterase activity showed no significant increase overall, but increased at least twofold in 5 of 12 subjects.

    The incidence of allergies has recently been increasing worldwide. Immunoglobulin E (IgE)-mediated hypersensitivity is central to the pathogenesis of asthma, hay fever and other allergic diseases. Ginger (Zingiber officinale Roscoe) and its extracts have been valued for their medical properties including antinausea, antiinflammation, antipyresis and analgesia properties. In this study, we investigated the antiallergic effects of ginger and 6-gingerol, a major compound of ginger, using a mouse allergy model and primary/cell line culture system. In mice with ovalbumin (OVA)-induced allergic rhinitis, oral administration of 2% ginger diet reduced the severity of sneezing and nasal rubbing by nasal sensitization of OVA and suppressed infiltration of mast cells in nasal mucosa and secretion of OVA-specific IgE in serum. 6-Gingerol inhibited the expression of not only Th2 cytokines but also Th1 cytokines in OVA-sensitized spleen cells. Accordingly, 6-gingerol suppressed in vitro differentiation of both Th1 cells and Th2 cells from naïve T cells. In addition, 6-gingerol suppressed both superantigen staphylococcal enterotoxin B (SEB)- and anti-CD3-induced T cell proliferation. 6-Gingerol also abrogated PMA plus ionomycin- and SEB-induced IL-2 production in T cells, suggesting that 6-gingerol affected T cell receptor-mediated signal transduction rather than the antigen-presentation process. Indeed, 6-gingerol inhibited the phosphorylation of MAP kinases, calcium release and nuclear localization of c-fos and NF-κB by PMA and ionomycin stimulation. Thus, our results demonstrate that 6-gingerol suppresses cytokine production for T cell activation and proliferation, thereby not causing B cell and mast cell activation and resulting in prevention or alleviation of allergic rhinitis symptoms.

    This study aims to determine whether the combined blockade of IL-1β and TNF-α can alleviate the pathological allergic inflammatory reaction in the nasal mucosa and lung tissues in allergic rhinitis (AR) guinea pigs. Healthy guinea pigs treated with saline were used as the healthy controls. The AR guinea pigs were randomly divided into (1) the AR model group treated with intranasal saline; (2) the 0.1% nonspecific IgY treatment group; (3) the 0.1% anti-TNF-α IgY treatment group; (4) the 0.1% anti-IL-1β IgY treatment group; (5) the 0.1% combined anti-IL-1β and TNF-α IgY treatment group; and (6) the fluticasone propionate treatment group. The inflammatory cells were evaluated using Wright's staining. Histopathology was examined using hematoxylin-eosin staining. The results showed that the number of eosinophils was significantly decreased in the peripheral blood, nasal lavage fluid, and bronchoalveolar lavage fluid (P < 0.05), and eosinophil, neutrophil, and lymphocyte infiltration and edema were significantly reduced or absent in the nasal mucosa and lung tissues (P < 0.05) in the combined 0.1% anti-IL-1β- and TNF-α IgY-treated guinea pigs. The data suggest that topical blockade of IL-1β and TNF-α could reduce pathological allergic inflammation in the nasal mucosa and lung tissues in AR guinea pigs.

    Nuclear antigens are known to trigger off innate and adaptive immune responses. Recent studies have found that the complex of nucleic acids and core histones that are derived from damaged cells may regulate allergic responses. However, no fundamental study has been performed concerning the role of linker histone H1 in mast cell-mediated type I hyperreactivity. In this study, we explored the impact of histone H1 on mast cell-mediated allergic responses both in vitro and in vivo. In the course of a bona-fide experimental allergen sensitization model upon co-injection with alum adjuvant, ovalbumin (OVA), but not PBS, induced elevated levels of circulating histone H1. Intranasal challenge with histone H1 to OVA/alum- (but not PBS/alum)-sensitized mice induced significantly severer symptoms of allergic rhinitis than those in mice sensitized and challenged with OVA. A monoclonal antibody against histone H1 not only suppressed mast cell degranulation, but also ameliorated OVA-induced nasal hyperreactivity and IgE-mediated passive cutaneous anaphylaxis. Our present data suggest that nuclear histone H1 represents an alarmin-like endogenous mediator acting on mast cells, and that its blockage has a therapeutic potential for mast cell-mediated type I hyperreactivity.

    Calcium-activated potassium ion channel-3.1 (KCa3.1) plays a pivotal role in the potassium-calcium exchange involved in atopy. This study aimed to explore the impact of lentiviral-mediated shRNA silencing KCa3.1 on allergic response in a murine allergic rhinitis (AR) model. The BALB/c mice were divided into four groups: untreated AR group, negative control AR group, lentiviral KCa3.1-shRNA treated AR group and normal control group. Concentrations of ovalbumin (OVA)-specific IgE, histamine and leukotrienes C4 (LTC4) in serum, and IL-4, IL-9 and IL-17 in nasal lavage fluid (NLF) were analyzed. Goblet cells and mast cells were counted. KCa3.1 positive cells were counted after immunolabelling by immunofluorescence method. KCa3.1, Mucin 5AC (MUC5AC), and tryptase mRNA levels were determined using real-time polymerase chain reaction. Furthermore, P815 cell line was used to explore the role and mechanism of lentiviral KCa3.1-shRNA on mast cells. The results showed that LV-KCa3.1-shRNA intervention effectively attenuated allergic responses in LV-KCa3.1-shRNA treated mice. LV-KCa3.1-shRNA intervention effectively suppressed KCa3.1 levels and phosphorylation of AKT in P815 cells, leading to the downregulation of tryptase, IL-6 and IL-8 levels. LV-KCa3.1-shRNA intervention effectively attenuated the allergic responses in AR and suppressed mast cell activity by inhibiting PI3K/AKT signaling pathway. PMID:26272420

    The aim of the study was to clarify the relationship between current pet ownership, passive smoking, and allergic diseases among the Japanese children. From 1995 to 2001, we distributed the Japanese edition of the questionnaire of the American Thoracic Society and the Division of Lung Diseases (ATS-DLD) to survey allergic diseases among 35,552 6-yr-old children at primary school in the city of Himeji, Japan. We analyzed the data by multiple logistic regression and calculated adjusted odds ratios for environmental factors, including passive smoking and pet (dog and/or cat) ownership. There were no significant relationships between the prevalence of asthma and current pet ownership and passive smoking. However, current cat ownership was related to a significantly lower prevalence of atopic dermatitis [adjusted odds ratio (aOR) 0.79, 95% confidence interval (CI) 0.67-0.93], allergic rhinitis (aOR: 0.71, 95% CI 0.57-0.89) and Japanese cedar pollinosis (aOR 0.57, 95% CI 0.44-0.75). Strikingly, passive smoking was also related to a significantly lower prevalence of allergic rhinitis (aOR 0.83, 95% CI 0.77-0.89) and Japanese cedar pollinosis (aOR 0.81, 95% CI 0.74-0.88). Current cat ownership was associated with a lower prevalence of atopic dermatitis, allergic rhinitis, and Japanese cedar pollinosis. In addition, passive smoking was also associated with a lower prevalence of allergic rhinitis and Japanese cedar pollinosis.

    Background In asthmatic patients with allergic rhinitis (AR), increased cysteinyl leukotrienes (CysLTs) production in the secretion of nasal mucosa has been associated with greater bronchial hyperresponsiveness (BHR) after nasal allergen challenge. However, the role of CysLTs in eliciting BHR after nasal allergen challenge has not been evaluated. The aim of this study is to evaluate the effect of LTD4 nasal challenge on BHR and inflammation in asthmatic patients with AR. Methods In this self-controlled study, fifteen eligible consecutively recruited subjects underwent methacholine (Mch) bronchial provocation test before and 30 minutes after LTD4 nasal provocation test. The cumulative concentration of LTD4 inducing a 60% increase in nasal airway resistance (PC60NAR) was calculated. The mean values of cumulative doses inducing a 20% decrease in forced expiratory flow in one second (PD20FEV1) for Mch before and after nasal challenge were compared. Fractional exhaled nitric oxide (FeNO), differential inflammatory cell counts in nasal lavage and induced sputum before and after nasal challenge were compared. Results House dust mites were the major allergens accounting for 10/15 (66.7%) of asthmatic patients with AR. The PC60NAR for LT was (8.39±3.48)×10−3 mg·mL−1. The PD20FEV1 before and after nasal challenge was 3.05±3.81 and 2.70±3.81 µmol, respectively (P=0.45). The percentages of eosinophils were (38.36±23.14)% and (45.70±24.86)% in nasal lavage, and (17.51±11.05)% and (24.29±16.52)% in induced sputum before and 24 hours after nasal challenge. The neutrophil counts were (60.64±23.14)% and (53.30±24.46)% in nasal lavage, and (53.83±23.27)% and (56.19±22.28)% in induced sputum before and 24 hours after nasal challenge. The values of FeNO were 40 [35] and 43 [30] ppb before and 24 hours after nasal challenge. No severe adverse effects were reported during the tests. Conclusions Although most asthmatic patients with AR were sensitive to LTD4 nasal

    Background We demonstrated that a Chinese herbal formula, which we refer to as RCM-101, developed from a traditional Chinese medicine formula, reduced nasal and non-nasal symptoms of seasonal allergic rhinitis (SAR). The present study in primary and cultured cells was undertaken to investigate the effects of RCM-101 on the production/release of inflammatory mediators known to be involved in SAR. Methods Compound 48/80-induced histamine release was studied in rat peritoneal mast cells. Production of leukotriene B4 induced by the calcium ionophore A23187 was studied in porcine neutrophils using an HPLC assay and lipopolysaccharide-stimulated prostaglandin E2 production was studied in murine macrophage (Raw 264.7) cells by immune-enzyme assay. Expression of cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) was determined in Raw 264.7 cells, using western blotting techniques. Results RCM-101 (1–100 μg/mL) produced concentration-dependent inhibition of compound 48/80-induced histamine release from rat peritoneal mast cells and of lipopolysaccharide-stimulated prostaglandin E2 release from Raw 264.7 cells. Over the range 1 – 10 μg/mL, it inhibited A23187-induced leukotriene B4 production in porcine neutrophils. In addition, RCM-101 (100 μg/mL) inhibited the expression of COX-2 protein but did not affect that of COX-1. Conclusion The findings indicate that RCM-101 inhibits the release and/or synthesis of histamine, leukotriene B4 and prostaglandin E2 in cultured cells. These interactions of RCM-101 with multiple inflammatory mediators are likely to be related to its ability to reduce symptoms of allergic rhinitis. PMID:17302969

    The effect of biological (pollen) and chemical air pollutants on respiratory hospital admissions for the Szeged region in Southern Hungary is analysed. A 9-year (1999-2007) database includes—besides daily number of respiratory hospital admissions—daily mean concentrations of CO, PM10, NO, NO2, O3 and SO2. Two pollen variables ( Ambrosia and total pollen excluding Ambrosia) are also included. The analysis was performed for patients with chronic respiratory complaints (allergic rhinitis or asthma bronchiale) for two age categories (adults and the elderly) of males and females. Factor analysis was performed to clarify the relative importance of the pollutant variables affecting respiratory complaints. Using selected low and high quantiles corresponding to probability distributions of respiratory hospital admissions, averages of two data sets of each air pollutant variable were evaluated. Elements of these data sets were chosen according to whether actual daily patient numbers were below or above their quantile value. A nonparametric regression technique was applied to discriminate between extreme and non-extreme numbers of respiratory admissions using pollen and chemical pollutants as explanatory variables. The strongest correlations between extreme patient numbers and pollutants can be observed during the pollen season of Ambrosia, while the pollen-free period exhibits the weakest relationships. The elderly group with asthma bronchiale is characterised by lower correlations between extreme patient numbers and pollutants compared to adults and allergic rhinitis, respectively. The ratio of the number of correct decisions on the exceedance of a quantile resulted in similar conclusions as those obtained by using multiple correlations.

    Maternal fish intake during pregnancy may influence the risk of child asthma and allergic rhinitis, yet evidence is conflicting on its association with these outcomes. We examined the associations of maternal fish intake during pregnancy with child asthma and allergic rhinitis. Mothers in the Danish National Birth Cohort (n 28 936) reported their fish intake at 12 and 30 weeks of gestation. Using multivariate logistic regression, we examined the associations of fish intake with child wheeze, asthma and rhinitis assessed at several time points: ever wheeze, recurrent wheeze (>3 episodes), ever asthma and allergic rhinitis, and current asthma, assessed at 18 months (n approximately 22,000) and 7 years (n approximately 17,000) using self-report and registry data on hospitalisations and prescribed medications. Compared with consistently high fish intake during pregnancy (fish as a sandwich or hot meal > or equal to 2-3 times/week), never eating fish was associated with a higher risk of child asthma diagnosis at 18 months (OR 1·30, 95% CI 1·05, 1·63, P=0·02), and ever asthma by hospitalisation (OR 1·46, 95% CI 0·99, 2·13, P=0·05) and medication prescription (OR 1·37, 95% CI 1·10, 1·71, P=0·01). A dose-response was present for asthma at 18 months only (P for trend=0·001). We found no associations with wheeze or recurrent wheeze at 18 months or with allergic rhinitis. The results suggest that high (v. no) maternal fish intake during pregnancy is protective against both early and ever asthma in 7-year-old children.

    Concerning allergic diseases, the incidence of allergic symptoms, as well as their severity, seems to decrease with age. The decline of onset of allergic symptoms observed in ageing might result from a decrease of serum total and specific IgE. Atopic disorders are complex diseases that involve interactions among several physiological systems, e.g. skin, lung, mucosae, and the immune system. It was the aim of this study to compare the effects of age on total and specific IgE in patients with atopic dermatitis (AD), allergic rhinitis or asthma, and insect allergy, respectively. The study population consisted of 559 individuals (male: 229 and female: 330). Total and allergen specific IgE was measured in every individual. From the whole study population, 113 patients suffered from atopic dermatitis (AD), 132 had allergic rhinitis or asthma, and 314 were tested because of insect allergy. Total and specific serum IgE was significantly decreased as a function of age in patients with allergic rhinitis and asthma and with insect allergy. In contrast, no significant decrease of total and specific serum IgE in old individuals with AD was observed. Additionally, in the group of patients with a total IgE < 300 kU/l a reduction of total serum IgE was significantly correlated with age. In contrast, patients with IgE levels > 300 kU/l showed no correlation with age. Immunosenescence does not affect increased IgE levels in atopic patients with AD and/or high serum IgE levels indicating that in these subgroups of patients the atopic propensity remains into advanced age. One may hypothesize that either onset of allergic sensitization during life or the kind of atopic disease influences the correlation between age and IgE synthesis. PMID:15927080

    Efficacy monitoring of immunotherapy (IT) is performed to adjust the therapy according to the patient's reactions, to collect data for scientific studies and to evaluate the efficacy of IT. A decrease of allergy symptoms and of drug use are the main parameters. For this, allergy diaries are most suitable. Pollen exposition should be monitored with Burkhard traps. Wheal and flare reactions in skin tests can be measured by visual inspection with quantification of the diameter on transparent foils or by means of laser scanners. Nasal provocation testing leads to subjective and objective (rhinomanometry, acoustic rhinometry) results. A change in the threshold concentration of allergen, which is needed to provoke a positive test reaction, can be used to evaluate the success of an IT. Additionally, systemic or local side-effects should be carefully revealed. Cytologic measures can be achieved by nasal lavages. Cotton samplers, cytology brushes and suction techniques are used to collect cells and nasal secretions. Early and late allergic reactions can be evaluated. Specific cell activation markers like ECP or tryptase are useful parameters in nasal secretions. T-lymphocyte subpopulations and T-cell-lymphokine-profiles can be detected. During IT, a change from a dominating TH2-cytokine-profile to a dominating TH1-cytokine-profile can be seen. For the reason of their expense, those methods are restricted to scientific investigations and only rarely used for routine diagnostics.

    Sneezing and persistent itching of the nasal mucosa are distressing symptoms of allergic rhinitis (AR). Recent studies have revealed that hyperinnervation of sensory neurons in the nasal turbinate is one of the underlying causes of sneezing and itching. Since Semaphorin-3A (Sema3A) has been previously shown to restrict innervation of sensory neurons, it is presumed that reduced Sema3A expression in the nasal mucosa might contribute to the hypersensitivity. Analysis of the mouse model of ovalbumin-sensitized AR demonstrated a decreased expression of Sema3A in the nasal epithelium, which was accompanied by an increased nerve fiber density in the lamina propria of the turbinate. In rescue experiments, intranasal administration of recombinant Sema3A in the AR model mice alleviated sneezing and nasal rubbing symptoms. In addition, histological examinations also revealed that nerve fiber density was decreased in the lamina propria of the Sema3A-treated nasal turbinate. These results suggest that the nasal hypersensitivity of AR may be attributed to reduction of Sema3A expression and intranasal administration of Sema3A may provide a novel approach to alleviate the allergic symptoms for AR treatment.

    Background Th2-type T cell response has a considerable role in atopic diseases. The involvement of Th17 and IL-17 in atopy process provided new understanding of allergic diseases. Bronchial hyperresponsiveness is quite common in allergic rhinitis. We aimed to explore the expression of IL-17 producing CD3+ CD4+ T cells in peripheral blood of rhinitic patients, with/without bronchial hyperresponsiveness and sensitized to common allergens, as this relationship has not been examined. Methods Sixty one patients with allergic rhinitis and thirty controls were examined. IL-17 producing T cells were detected by flow cytometry, IL-17, IL-4 and IL-13 levels in peripheral blood were evaluated by ELISA. Bronchial hyperresponsiveness was investigated with methacholine challenge test. Atopy was evaluated by skin prick tests with common allergens. Results IL-17 producing T cell percentage of AR group was significantly higher: 2.59 ± 1.32 than in controls 1.24 ± 0.22, (p = 0.001). Significant sex related difference in CD3+ CD4+ IL-17 T cells was observed: respectively in male patients versus female 3.15 ± 1.8% and 2.31 ± 0.9%, (p = 0.02). Rhinitics had greater bronchodilator responses compared to controls (p = 0.001), however the percentages of T cells in both groups appeared equal. Serum IL-17 levels in AR group were significantly higher (5.10 ± 4.40) pg/ml than in controls (3.46 ±1.28) pg/ml, (p = 0.04). IL-4 levels (0.88 ± 1.27) and IL-13 levels (3.14 ± 5.85) in patients were significantly higher than in control’s (0.54 ± 0.10) pg/ml, (p = 0.001) and (1.19 ± 0.64) pg/ml; (p = 0.001) respectively. The percentages of T cells in patients sensitized to 5 allergens (group I) were significantly lower (1.91 ± 0.62) than those sensitized to more than 5 allergens (group II) (2.91 ± 1.5) (p = 0.004). Conclusions The observed higher levels of IL-17 producing T cells in polysensitized males suggest a role of IL-17 in pathogenesis of AR. The higher airway responsiveness in AR

    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

    We evaluated the clinical improvement of patients with mild to moderate persistent allergic rhinitis (AR) due to mono-sensitization to house dust mite (HDM) allergen, by sodium cromoglycate nasal spray (Lomusol 4%). Lomusol was used as a single agent treatment, and its anti-inflammatory effects, in the early phase reaction were evaluated. Herein we showed that Lomusol significantly improved the subjective nasal symptom scores especially nasal obstruction. This was associated with significant and specific reduction in neutrophils influx in nasal cytology but had no effect on other cell types. This selective anti-inflammatory effect on nasal cytology was associated with significant reduction in the levels of platelet activating factor (PAF) and histamine in nasal secretions but had no effect on PGD2, LTC4 or CysLt levels. Lomusol was also able to induce significant reduction in eosinophil cationic protein (ECP) levels in nasal secretions without altering the percentage of eosinophil influx in nasal cytology. Taken collectively, we showed the first evidence that nasal sodium cromoglycate possesses a selective inhibition on neutrophil recruitment into nasal cytology in the early phase reaction of AR patients mono-sensitized to HDM. This may be attributed to the ability of Lomusol to significantly reduce the amount of PAF recovered in nasal secretion. These results were associated with significant improvement in subjective symptom scores especially nasal obstruction that may in addition, be due to the ability of Lomusol to down-regulate eosinophil degranulation activity as well.

    Allergic Rhinitis is typically characterized by sneezing, rhinorrhoea, nasal obstruction, nasal, conjunctival & pharyngeal itching and lacrimation all occurring in a temporal relation to allergen exposure. The peak incidence of this disease occurs in childhood and adolescence, with most of the cases belonging to the atopic category. There is a high incidence of patients of allergic rhinitis attending the outdoor sections of Ajmal Khan Tibbiya College Hospital. Many of them are dissatisfied with conventional anti-histaminic drugs. An open study was carried out on 20 such patients aged between 15 to 50 years to evaluate the clinical efficacy of a unani pharmacopeal preparation [Itrifal ustukhudoos] added with cloves [qaranfal]. Preliminary clinical study showed promising results. The study is into the next phase in which a comparative double-blind trial is being conducted with this combination and Allegra (Fexofenadine hydrochloride). PMID:22557103

    Background Allergic rhinitis is a global health problem that burdens society due to associated health care costs and its impact on health. Standardized quality (SQ®) house dust mite (HDM) sublingual immunotherapy (SLIT)-tablet is a sublingually administered allergy immunotherapy tablet for patients with persistent moderate to severe HDM allergic rhinitis despite use of allergy pharmacotherapy. Objective To assess the cost-effectiveness of SQ HDM SLIT-tablet in Germany for patients suffering from HDM allergic rhinitis. Methods A pharmacoeconomic analysis, based on data collected in a double-blinded, phase III randomized placebo-controlled trial (n=992), was undertaken to compare SQ HDM SLIT-tablet in addition to allergy pharmacotherapy to placebo plus allergy pharmacotherapy. Quality-adjusted life year (QALY) scores and health care resource use data recorded in the trial were applied to each treatment group and extrapolated over a nine-year time horizon. A series of scenarios were used to investigate the impact of changes on long-term patient health for both treatment groups, which was measured by annual changes in QALY scores. Deterministic and probabilistic sensitivity analyses were also performed. Results In the base case analysis, compared with allergy pharmacotherapy, SQ HDM SLIT-tablet led to a QALY gain of 0.31 at an incremental cost of €2,276 over the nine-year time horizon, equating to an incremental cost-effectiveness ratio of €7,519. The treatment was cost-effective for all scenarios analyzed; however, results were sensitive to changes in individual parameter values during the deterministic sensitivity analysis. Conclusion SQ HDM SLIT-tablet in addition to pharmacotherapy is cost-effective compared with allergy pharmacotherapy plus placebo for the treatment of persistent moderate to severe HDM allergic rhinitis that is not well controlled by allergy pharmacotherapy.

    The herbal medicine shoseiryu-to is an effective agent in the treatment of allergic rhinitis. However, the mechanism by which it exerts its action in improving patient symptoms remains unclear. It might affect the allergen-induced TH1 and/or TH2 responses. This study investigated whether the herbal medicine could affect cytokine synthesis by peripheral blood mononuclear cells (PBMCs) in response to the major Dermatophagoides farinae (D. farinae) allergen, Der f 1. PBMCs were obtained from 15 patients with perennial allergic rhinitis due to D. farinae, and were stimulated for 96 h with 10 micrograms/ml Der f 1 in the presence or absence of 45 mg/ml shoseiryu-to. The culture supernatants were harvested to determine the synthesis of IgE, interleukin 5 (IL-5), IL-6, IL-10, interferon-gamma (IFN-gamma) and tumour necrosis factor alpha (TNF-alpha). The agent did not affect the allergen-induced synthesis of IL-5, IL-6 and IFN-gamma, but somewhat decreased the synthesis of IgE and IL-10. This study highlighted an interesting pharmacological action of shoseiryu-to to substantially inhibit the allergen-induced synthesis of TNF-alpha. Our study suggests that the shoseiryu-to may alleviate nasal symptoms in allergic rhinitis through control of the allergen-induced inflammatory process.

    Background IL-9 is an important stimulus for tissue infiltration by mast cells, a feature requiring concomitant activation of c-Kit. Objectives We assessed IL-9 expression and c-Kit + mast cells in the nasal mucosa of patients with allergic rhinitis during seasonal pollen exposure and observed the effects of allergen immunotherapy. Methods We studied 44 patients with seasonal rhinitis and asthma before and 2 years after a double-blind trial of grass pollen immunotherapy. Nasal mucosal IL-9 + cells and c-Kit + mast cells were assessed by means of immunochemistry. Cell types expressing IL-9 protein were determined by means of dual immunofluorescence. IL-9 mRNA-positive cells were assessed by means of in situ hybridization, and their phenotype was determined by using sequential immunohistochemistry and in situ hybridization. Results Nasal mucosal c-Kit + mast cells were increased during the pollen season ( P = .0001). IL-9 mRNA-positive cells also tended to increase ( P = .1) and correlated with nasal EG2 + eosinophils ( r = 0.47, P = .05) and IL-5 mRNA-positive cells ( r = 0.54, P = .02). The cell sources of IL-9 included T cells, eosinophils, neutrophils, and mast cells. When compared with placebo, successful pollen immunotherapy markedly inhibited seasonal increases in nasal mucosal c-Kit + mast cells ( P = .001) and the seasonal expression of IL-9 mRNA-positive cells ( P = .06). Immunotherapy also inhibited IL-9 protein expression from nonendothelial cell sources ( P = .0007). Conclusion IL-9 is upregulated in the nasal mucosa during the pollen season and correlates with tissue infiltration by eosinophils. Successful pollen immunotherapy is associated with inhibition of seasonal increases in both nasal c-Kit + mast cells and eosinophils. This effect might be explained, at least in part, by the reduced local expression of IL-9.

  10. Genetic analysis of an allergic rhinitis cohort reveals an intercellular epistasis between FAM134B and CD39

    PubMed Central

    2014-01-01

    Background Extracellular ATP is a pro-inflammatory molecule released by damaged cells. Regulatory T cells (Treg) can suppress inflammation by hydrolysing this molecule via ectonucleoside triphosphate diphosphohydrolase 1 (ENTPD1), also termed as CD39. Multiple studies have reported differences in CD39+ Treg percentages in diseases such as multiple sclerosis, Hepatitis B and HIV-1. In addition, CD39 polymorphisms have been implicated in immune-phenotypes such as susceptibility to inflammatory bowel disease and AIDS progression. However none of the studies published so far has linked disease-associated variants with differences in CD39 Treg surface expression. This study aims at identifying variants affecting CD39 expression on Treg and at evaluating their association with allergic rhinitis, a disease characterized by a strong Treg involvement. Methods Cohorts consisting of individuals of different ethnicities were employed to identify any association of CD39 variants to surface expression. Significant variant(s) were tested for disease association in a published GWAS cohort by one-locus and two-locus genetic analyses based on logistic models. Further functional characterization was performed using existing microarray data and quantitative RT-PCR on sorted cells. Results Our study shows that rs7071836, a promoter SNP in the CD39 gene region, affects the cell surface expression on Treg cells but not on other CD39+ leukocyte subsets. Epistasis analysis revealed that, in conjunction with a SNP upstream of the FAM134B gene (rs257174), it increased the risk of allergic rhinitis (P = 1.98 × 10-6). As a promoter SNP, rs257174 controlled the expression of the gene in monocytes but, notably, not in Treg cells. Whole blood transcriptome data of three large cohorts indicated an inverse relation in the expression of the two proteins. While this observation was in line with the epistasis data, it also implied that a functional link must exist. Exposure of monocytes to

    Occupational rhinitis (OR) involves nasal congestion, rhinorrhea, nasal itching, and/or sneezing resulting from workplace exposures. OR can have a significant negative effect on quality of life and productivity. OR can be divided into allergic or nonallergic subgroups based on the underlying pathogenesis. Certain occupational exposures place employees at greater risk for developing disease. Primary treatment is avoidance of implicated exposures. Antihistamines, saline rinses, and nasal steroids may be useful. OR can coexist with occupational asthma, and rhinitis symptoms have been reported to precede those of the lower respiratory tract. OR is has both medical and socioeconomic implications.

    Background The transcription factor (TF) IRF4 is involved in the regulation of Th1, Th2, Th9 and Th17 cells, and animal studies have indicated an important role in allergy. However, IRF4 and its target genes have not been examined in human allergy. Methods IRF4 and its target genes were examined in allergen-challenged CD4+ cells from patients with IAR using combined gene expression microarrays and chromatin immunoprecipitation chips (ChIP-chips), computational target prediction and RNAi knockdowns. Results IRF4 increased in allergen-challenged CD4+ cells from patients with IAR and functional studies supported its role in Th2 cell activation. IRF4 ChIP-chip showed that IRF4 regulated a large number of genes relevant for Th cell differentiation. However, neither Th1 nor Th2 cytokines were the direct targets of IRF4. To examine if IRF4 induced Th2 cytokines via one or more down-stream TFs, we combined gene expression microarrays, ChIP-chips and computational target prediction and found a putative intermediary TF, namely ETS1 in allergen-challenged CD4+ cells from allergic patients. ETS1 increased significantly in allergen-challenged CD4+ cells from patients compared to controls. Gene expression microarrays before and after ETS1 RNAi knockdown showed that ETS1 induced Th2 cytokines as well as disease-related pathways. Conclusions Increased expression of IRF4 in allergen-challenged CD4+ cells from patients with intermittent allergic rhinitis, leads to activation of a complex transcriptional program, including Th2 cytokines.

    The therapeutic efficacy of allergen specific immunotherapy (SIT) on allergic diseases is to be improved. Probiotics can regulate immune response. This study aims to promote the effect of SIT on allergic rhinitis (AR) by co-administration with Clostridium butyricum (Cb). In this study, patients with AR sensitized to mite allergens were enrolled to this study, and treated with SIT or/and Cb. The therapeutic efficacy was evaluated by the total nasal symptom scores (NSS), medication scores, serum specific IgE levels and T helper (Th)2 cytokine levels. The improvement of immune regulation in the AR patients was assessed by immunologic approaches. The results showed that treating AR patients with SIT alone markedly reduced NSS and medication scores; but did not alter the serum specific IgE, Th2 cytokines and skin prick test (SPT) index. The clinical symptoms on AR in SIT group relapsed one month after stopping SIT. Co-administration of Cb significantly enhanced the efficacy of SIT on AR as shown by suppression of NSS, medication scores, serum specific IgE, Th2 cytokines and SPT index; the regulatory B cell frequency was also markedly increased. Such an effect on AR was maintained throughout the observation period even after stopping the treatment. Butyrate blocked the activation of histone deacetylase-1, the downstream activities of epsilon chain promoter activation, and the IgE production in the antigen specific B cells. On the other hand, butyrate induced the IL-10 expression in B cells with a premise of the B cell receptor activation by specific antigens. In conclusion, administration with Cb can markedly enhance the efficacy of SIT on AR. PMID:27486985

    In the clinic, approximately 30% of children with adenoid hypertrophy (AH) concomitant with allergic rhinitis (AR) report poor responses to intranasal steroids. To determine whether the combination of mometasone furoate (MF) and oxymetazoline (OXY) is more effective than either agent alone, we performed a two-stage, parallel, randomized, double-blind, double-dummy, clinical trial with 240 AH children with concomitant perennial AR. During the first stage, all children were randomly assigned to the MF or control group for six weeks of treatment. During the second stage, the non-responders from stage one were randomly assigned to 4 groups for 8 weeks of treatment that involved receiving the following treatments: MF/OXY, MF/placebo, placebo/OXY, or placebo/placebo. During the first stage of treatment, 39% of the responders treated with MF achieved greater reductions in total and individual symptom scores than did those on placebo. During the second stage of treatment, the nasal congestion scores of the MF/OXY group significantly decreased. The adenoid/choana ratio of the MF/OXY-treated group decreased and the nasal volume increased significantly. Our results suggest that the combination of OXY and MF is effective and safe for the treatment of AH children with concomitant AR and has a rapid onset of action. PMID:28098165

    Allergic rhinitis (AR) triggered by grass pollen is a common disease, affecting millions of people worldwide. Treatment consists of symptom-alleviating drugs, such as topical corticosteroids or antihistamines. Another option is potentially curative immunotherapy, currently available as sublingual and subcutaneous treatment. We investigated the potential differences in the prevalence and severity of adverse events related to subcutaneous and sublingual immunotherapy (SLIT) against grass pollen-induced AR. A thorough literature search was performed with PubMed and EMBASE. The findings were compared with the available summaries of product characteristics (SPC) and with commercial pharmacology databases (Micromedex). The majority of available safety data originate from registered products of standardized allergens. A surprisingly large percentage of drugs, especially those used in the United States, have no systematically collected safety data. No sufficiently powered randomized trials comparing sublingual and subcutaneous immunotherapy (SCIT) were available, but general safety assessments indicate that sublingual tablet treatment is safer than subcutaneous treatment. Not all commonly used immunotherapy drugs are officially registered, and not all have systematically collected safety data. This is especially true for older drugs used in the United States. In contrast, newer drugs that have undergone extensive clinical testing have better documentation, but unified collection of safety data is still lacking. Considering the evidence available, most drugs elicit similar side effects from the same organ systems, and symptoms from the sublingual drug classes are probably less severe. However, a head-to-head comparison of safety and efficacy is lacking.

    Symptom and medication use are the key outcomes for assessing the efficacy of subcutaneous (SCIT) and sublingual allergen immunotherapy (SLIT). Our objective was to explore the similarities and differences between existing scoring mechanisms used in clinical trials of SLIT for seasonal allergens and characterize the impact that such differences may have on efficacy reporting. Randomized, double-blind, placebo-controlled clinical trials investigating the efficacy of SLIT for seasonal allergic rhinitis (2009-2013) were selected for review. Simulated and published data were used to demonstrate differences in scoring methods. Symptom and medication scoring methods across trials, although all designed to achieve the same objective, included important differences. The maximum daily symptom score (DSS) can vary widely depending on the number of symptoms assessed, and terminology of symptoms is not consistent. Similarly, daily medication scoring (DMS) methods differ greatly among studies and are dependent on medications allowed and weighting of scores assigned to each medication. When published DSS and DMS scores were used to calculate simulated daily combined scores (DCSs) based on various published methods, changes from placebo ranged from 19% to 29% when assuming all variables other than the DSS and DMS methods were equal. Variations in trial design, analysis, and seasonal characteristics also have effects on symptom and medication scoring outcomes. We identified multiple differences in trial scoring methods and design that make comparison among trials difficult. Symptom, medication, or combined scores cannot be indirectly compared among trials without taking the methods of scoring and other trial differences into account.

    Nasal hyperresponsiveness (NHR) is a characteristic feature of allergic rhinitis (AR); however, the pathogenesis of NHR is not fully understood. In this study, during the establishment of an experimental AR model using ovalbumin-immunized and -challenged mice, augmentation of the sneezing reaction in response to nonspecific proteins as well as a chemical stimulant was detected. Whether NHR is independent of mast cells and eosinophils was determined by using mast cell- and eosinophil-deficient mice. NHR was suppressed by treatment with anti-CD4 antibody, suggesting the pivotal contribution of CD4+ T cells. Furthermore, antigen challenge to mice to which in vitro-differentiated Th1, Th2, and Th17 cells but not naïve CD4+ T cells had been adoptively transferred led to the development of equivalent NHR. Since antigen-specific IgE and IgG were not produced in these mice and since antigen-specific IgE-transgenic mice did not develop NHR even upon antigen challenge, humoral immunity would be dispensable for NHR. CD4+ T cells play a crucial role in the pathogenesis of AR via induction of NHR, independent of IgE-, mast cell-, and eosinophil-mediated responses. PMID:26752722

    The development of allergic rhinitis is considered to be caused by the complex interactions between genetic predisposition and environmental factors. Polymorphisms in the interleukin (IL)-13/4/4RA pathway have previously been shown to be associated with atopic diseases. The purpose of this study was to determine the association between IL-13 R130Q, IL-4 T589C, IL4 receptor alpha (IL-4RA) I50V, or IL-4RA Q576R polymorphisms and risk of allergic rhinitis in a hospital-based Malaysian population. A case-control pilot study was undertaken and genotyping of these polymorphisms was performed using polymerase chain reaction–restriction fragment length polymorphism on 54 allergic rhinitis patients and 45 healthy individuals. Polymorphism of IL-13 R130Q showed significant difference in genotype (p = 0.048) and allele (p = 0.002) frequencies in allergic rhinitis when compared with healthy controls. Individuals who were GA heterozygotes (adjusted odds ratio [ORadj] = 3.567; 95% CI, 1.211–10.509), and carriers of A allele genotype (ORadj = 3.686; 95% CI, 1.300–10.451) and A allele (ORadj = 3.071; 95% CI, 1.514–6.232) had an elevated risk of developing allergic rhinitis. The genotype and allele frequencies of IL-4 T589C, IL-4RA I50V, and IL-4RA Q576R polymorphisms were not significantly different between the allergic rhinitis patients and normal healthy individuals and did not show an associated risk with allergic rhinitis. Our findings indicate that polymorphic variant of IL-13 R130Q appears to be associated with increased risk for development of allergic rhinitis in a hospital-based Malaysian population but not IL-4 T589C, IL-4RA I50V, and IL-4RA Q576 polymorphisms. Additional studies using larger sample size are required to confirm our findings and its exact role in allergic rhinitis. PMID:22852128

The current two noninterventional trials evaluated the efficacy and safety of ectoine containing nasal spray and eye drops for treating allergic rhinitis in comparison with either azelastine or cromoglycic acid containing products. Nasal and ocular symptom developments as well as judgment of tolerability and efficacy were assessed both by investigators and patients over a time period of one to two weeks. Results. Both trials confirmed that ectoine containing products reduced nasal and ocular symptoms in allergic rhinitis patients. Results clearly demonstrated good safety profiles of the ectoine products comparable to those of azelastine and even better to those of cromoglycate products. Conclusion. Ectoine containing nasal spray and eye drops are interesting new treatment strategies for sufferers of allergic rhinitis, combining both good efficacy and absence of side effects.

    The link between upper and lower airways has been observed in the past, but only carefully investigated during the last years. Allergic rhinitis and asthma are often comorbid conditions. Its relationship is supported by epidemiological, anatomical and physiological, immunopathological, clinical and therapeutic studies, mostly related to allergic rhinitis. Rhinitis and asthma occur together at rates that greatly exceed what would be expected from the baseline prevalence of each disorder alone. Many researchers have considered rhinitis as a risk factor for developing asthma. Also, the severity of rhinitis has been directly correlated with the severity of asthma although less evidence supporting the reverse impact. Different clinical and experimental observations suggested the hypothesis of the unity of upper and lower respiratory tract. Evidence suggests that rhinitis and asthma are different facets of a broader systemic inflammatory process involving upper and lower airways. Treatment of rhinitis simultaneously produces a favorable effect on symptoms of asthma and concurrent improvement in lung function and bronchial hyperresponsiveness. In this article, we review the most relevant epidemiological, genetic and clinical evidence linking rhinitis and asthma, the possible mechanisms of the nose-lung interaction and the rational basis of a set treatment that support the hypothesis of "one airway, one disease "considering aspects not yet clarified on the subject.

    Recent studies have implicated that Hypoxia-inducible factor 1α (HIF-1α) plays an integral role in the pathogenesis of allergic rhinitis and asthma. In the present study, we showed that HIF-1α antagonist YC-1, 3-(5-hydroxymethyl-2-furyl)-1-benzylindazole, elicited a potent allergy-ameliorating effect in a rat model of ovalbumin (OVA)-sensitized combined allergic rhinitis and asthma syndrome (CARAS). We revealed that YC-1 administration markedly impaired the total number and percentage of eosinophil in bronchoalveolar lavage fluid (BAL Fluid) of the rats, suggesting that YC-1 might attenuate lung and nasal mucosal inflammation in OVA-sensitized rats. Moreover, histological examination found that OVA-induced pathological alterations were evidently attenuated following YC-1 administration. In addition, immunohistochemistrial analysis indicated that YC-1 treatment decreased the expression of HIF-1α in rat lungs and nasal mucosa. Notably, Nuclear factor kappa B (NF-κB) p65 and Peroxisome proliferator-activated receptor α (PPARα), two important regulators of inflammatory responses, were also significantly down-regulated following YC-1 administration. Real-time PCR analysis confirmed that YC-1 impaired the expression of HIF-1α, NF-κB and PPARα in CARAS model. These findings together indicated that YC-1 exerted remarkable anti-allergic effects through the modulation of inflammatory pathways, implying that YC-1 may potentially serve as a novel anti-CARAS medicine in clinical patients.

    Allergies are a widespread phenomenon and one that is in continuous expansion, especially in large cities. A heretofore underestimated allergen, at least in Italy, is the cockroach. Between April and June 2000, we administered a prick test (including the cockroach antigen in the allergen kit) to 163 patients. The prick test was executed utilizing histamine as the positive control and a normal diluent as the negative control; both indoor allergens (including dermatophagoids and dog and cat epithelium) and outdoor allergens (including trees, grasses, pollens and spores) were employed. The results obtained were evaluated by comparing the reaction provoked by these allergens to that of the histamine. About 20% of the patients who reacted to the other indoor allergens also tested positive to the cockroach antigen. Also on the basis of experiences previously carried out in other countries (United States, Korea, Japan, Turkey), the cockroach must be borne in mind as a possible significant cause of allergic reactions in Italy, too.

    Objectives Antimicrobial chemicals are used in a variety of household and personal care products. Exposure to antimicrobial household products has been hypothesized to lead to allergic diseases in children. Methods We investigated antimicrobial household product exposure and allergic symptoms in Korean children. An antimicrobial exposure (AE) score was derived. To examine the symptoms of allergic diseases (current wheeze, current rhinitis, and current eczema) in the past 12 months, we used a questionnaire based on the core module of the International Study of Asthma and Allergies in Children. Complete data for the analysis were available for 25,805 of the 35,590 (72.5%) children. Results The prevalence of current allergic diseases was as follows: wheeze, 5.6%; allergic rhinitis, 32.6%; and eczema, 17.7%. The mean (standard deviation) AE score was 14.3 (9.3) (range: 0-40). Compared with subjects with a low AE score (reference), subjects with a high AE score (fourth quartile) were more likely to have symptoms of wheezing and allergic rhinitis (adjusted odds ratio [aOR] for wheezing 1.24, 95% confidence interval [CI], 1.05-1.45, p for trend=0.24; aOR for allergic rhinitis 1.30, 95% CI, 1.20-1.40, p<0.01). Conclusions These findings suggest that frequent use of antimicrobial household products was associated with current wheeze and current allergic rhinitis. PMID:25420879

    Herbal therapies are being used increasingly for the treatment of allergic rhinitis. The aim of this study was to investigate the possible pharmacological actions and cellular targets of a Chinese herbal formula (RCM-101), which was previously shown to be effective in reducing seasonal allergic rhinitis symptoms in a randomized, placebo-controlled clinical trial. Rat and guinea pig isolated tissues (trachea and aorta) were used to study the effects of RCM-101 on responses to various mediators. Production of leukotriene B4 in porcine neutrophils and of prostaglandin E2 and nitric oxide (NO) in Raw 264.7 cells were also measured. In rat and guinea pig tracheal preparations, RCM-101 inhibited contractile responses to compound 48/80 but not those to histamine (guinea pig preparations) or serotonin (rat preparations). Contractile responses of guinea pig tracheal preparations to carbachol and leukotriene C4, and relaxant responses to substance P and prostaglandin E2 were not affected by RCM-101. In rat aortic preparations, precontracted with phenylephrine, endothelium-dependent relaxant responses to acetylcholine and endothelium-independent relaxant responses to sodium nitroprusside were not affected by RCM-101. However, RCM-101 inhibited relaxations to l-arginine in endothelium-denuded rat aortic preparations, which had been pre-incubated with lipopolysaccharide. RCM-101 did not affect leukotriene B4 formation in isolated porcine neutrophils, induced by the calcium ionophore A23187; however, it inhibited prostaglandin E2 and NO production in lipopolysaccharide-stimulated murine macrophages (Raw 264.7 cells).The findings indicate that RCM-101 may have multiple inhibitory actions on the release and/or synthesis of inflammatory mediators involved in allergic rhinitis.

    Recurrent vaginal candidiasis (RVC) is considered to be a hypersensitivity disorder that is associated with allergic rhinitis (AR) in immune deficiencies; however, whether or not the composition of the vaginal fungal flora in patients with AR and RVC is altered and if such alterations in patients with AR are associated with the development of RVC remain unclear. In the present study, a cultivation-independent method with the 18S rRNA gene clone library was used to analyze the diversity and composition of the vaginal fungal flora in patients with AR and RVC and to explore the association. Three fungal phyla (Ascomycotae, 22 out of 28; Basidiomycetes, 5 out of 28; and Oomycetes, 1 out of 28) were identified from groups of healthy volunteers, patients with AR, patients with RVC, and patients with RVC complicated by AR, including 28 phylotypes of fungal flora (10, 15, 17, and 21 phylotypes for each group, respectively). The predominant genera of fungi identified in the vagina included Candida, uncultured fungi, and Dothideomycetes. An increased proportion of Candida albicans accompanied with decreased proportions of Saccharomyces cerevisiae and uncultured fungi was observed in patients with AR or RVC (P < 0.05). Candida glabrata, Eladia saccula, Trichosporon jirovecii, and Phytophthora spp. occurred simultaneously in the three patient groups. The composition of the fungal communities in the four groups was statistically different (P < 0.001). The vaginal fungal diversity in patients with AR or RVC was significantly higher compared with healthy volunteers (P < 0.05). The data revealed an increased diversity and varied composition of the vaginal fungal flora in patients with AR and RVC and indicated that disturbed vaginal fungal flora in patients with AR might be correlated with disease progression in patients with RVC.

    Allergic rhinitis (AR) is a global health problem. The effectiveness of currently available medications is limited and therefore investigation for more effective drugs is essential. The aim of the present study was to establish a model of AR in guinea pigs that can be utilized for the further investigation of new drugs. Guinea pigs were intranasally sensitized with 1 µg Staphylococcal enterotoxin B (SEB) dissolved in 40 µl saline once daily for 14 days. One week after the last sensitization, the same treatment was applied intranasally once every four days for a total of 30 times. In the treatment group, terfenadine was administered orally 70 min before the 4th, 14th and 24th challenge. Sneezing and nasal scratching were evaluated following each of the 30 challenges. The quantity of antigen-specific antibodies in the serum was measured. Between the 19th and 30th challenges, the guinea pigs in the model group produced significant biphasic elevations in sneezing number, with peaks 10 min-2 h and 4-8 h after the SEB challenges. In addition, the guinea pigs produced significantly more sneezing in the first peak during the 19th to 30th challenges than during the first to 18th challenges (P<0.01). Terfenadine significantly inhibited the early- and late-phase sneezing at all challenge times. The serum levels of SEB-specific immunoglobulin (Ig) E and IgG1 were higher in the model group in comparison with those in the control group (P<0.01). This experiment demonstrated that SEB can induce typical AR with biphasic sneezing in guinea pigs. Histamine may play an important role in the early- and the late-phase sneezing in the model of AR. This model can be potentially used for the investigation of new drugs.

    Background The symptoms of allergic rhinitis (AR) greatly affect the quality of life (QoL) in the patients with AR. The correlations of nasal response to leukotriene D4 (LTD4) and histamine nasal provocation with health related QoL in AR are not clear. Objective To evaluate the correlations of nasal response to LTD4 and histamine nasal challenge with QoL in AR. Methods Patients randomly underwent LTD4 and histamine nasal challenge tests, completed the rhinoconjunctivitis quality of life questionnaire (RQoLQ), and rating the symptom severity score (total symptom score 4, TSS4) in the previous week. The correlations between nasal challenge tests induced nasal responses and QoL in RQoLQ were analyzed. Results A total of 25 eligible AR patients enrolled and finished both LTD4 and histamine nasal challenge and completed the questionnaire of RQoLQ. Histamine nasal challenge induced sneezing, increased nasal resistant were correlated with most of the dimensions (general, practical, nasal, eye problems, and quality of sleep, p < 0.05), while LTD4 nasal challenge induced sneeze, increased nasal resistant only correlated with nasal and ocular problems. On the contrary, the severity of the sneeze assessed by TSS4, was not correlated with QoL, while the severity of rhinorrhea, congestion, and nasal pruritus were correlated with nasal and practical problems, and nasal congestion was also correlated with ocular problems (r = 0.60, p = 0.01). Conclusion LTD4 and histamine nasal challenge induced nasal responses were correlated with different clinical symptoms severity and QoL, which can be used as a good diagnosis and evaluation methods for the management of AR.

    The aim of this study is to develop a locally acting nasal delivery system of triamcinolone acetonide (TA) for the maintenance therapy of allergic rhinitis. The effect of encapsulating TA in different nanocarriers on its mucosal permeation and retention as well as in vivo nasal deposition has been studied. A comparative study was established between polymeric oil core nanocapsules (NCs), lipid nanocarriers such as nanoemulsion (NE), and nanostructured lipid carriers (NLCs). The elaborated nanocarriers were compared with TA suspension and the commercially available suspension "Nasacort(®)". The study revealed that NC provided the highest mucosal retention, as 46.14%±0.048% of the TA initial dose was retained after 24 hours, while showing the least permeation through the nasal mucosa. On the other hand, for TA suspension and Nasacort(®), the mucosal retention did not exceed 23.5%±0.047% of the initial dose after 24 hours. For NE and NLC, values of mucosal retention were 19.4%±0.041% and 10.97%±0.13%, respectively. NC also showed lower mucosal irritation and superior stability compared with NE. The in vivo nasal deposition study demonstrated that NC maintained drug in its site of action (nasal cavity mucosa) for the longest period of time. The elaborated polymeric oil core NCs are efficient carriers for the administration of nasally acting TA as it produced the least permeation results, thus decreasing systemic absorption of TA. Although NCs have been administered via various routes, this is the first study to implement the polymeric oil core NC as an efficient carrier for localized nasal drug delivery.

    Cysteinyl leukotriene and leukotriene receptor occupancy have been linked to several processes in seasonal allergic rhinitis (SAR), including nasal congestion, rhinorrhea, and recruitment of inflammatory cells. We investigated whether add-on loratadine, an antihistamine, might be effective for SAR patients showing unsatisfactory control of symptoms with the leukotriene receptor antagonist (LTRA) montelukast alone. Patients with SAR caused by Japanese cedar pollen (SAR-JCP; mean age, 29.4 years) were given prophylactic montelukast for 1 month before peak JCP dispersal. Patients recorded the severity of the symptoms (sneezing, rhinorrhea, nasal congestion, and ocular symptoms) daily on visual analog scale (VAS). We selected patients with VAS scores of >50 for any of the symptoms just before the peak pollen season (March 2 to March 8) and designated them as "poorly controlled" patients. Then, in the peak JCP season (from March 9), we conducted a randomized, double-blind, placebo-controlled study to determine whether add-on loratadine might be effective for these "poorly controlled" patients. Montelukast alone was effective, as evaluated by improvement of the VAS scores, in 95 of the 137 patients (69.3%). Add-on loratadine significantly decreased the total scores for nasal symptoms (p < 0.05), sneezing (p < 0.05), and rhinorrhea (p < 0.05) when compared with placebo. The symptoms of SAR in two of three SAR-JP patients could be controlled (VAS score[s] under 50) by prophylactic treatment with montelukast alone under the condition of mild JCP dispersal. Furthermore, the effect of add-on antihistamine on sneezing and rhinorrhea was found in selected SAR-JCP patients.

    Detecting eosinophilia in the nasal secretions of patients complaining of nasal obstruction makes it possible to identify a group of high risk patients. Hosty use of surgery in these patients carries a high risk of iatrogenic complications and little potential for improvement. The 2 most frequently used methods of obtaining cytologic specimens (swabbing versus washing) were compared in 37 patients with obstructive rhinitis (early stage polyposis and nonallergic rhinitis with eosinophilia syndrome, NARES). Swabbing gave reliable results. Eosinophilia was negligible in a group of 25 control subjects. The mean eosinophil count was 2.5% and only 1 patient had a positive cystogram. The 220 patients which nasal obstruction were classed in 5 groups according to the severity of clinical signs and symptoms. The mean eosinophil count and the percentage of patients with positive cystogram increased with increased severity of the clinical syndrome. 28 patients had uncomplicated obstructive rhinitis, 10 had NARES, 43 had allergic rhinitis, 52 had chronic obstructive rhinitis, and 87 had nasosinal polyposis. The respective mean eosinophil counts were 6.42%, 10.3%, 13.8% 16.8% and 31.4%. The percentage of patients with positive cytograms was respectively, 10.8%, 20%, 23.3%, 28.8% and 54%.

    Aims: To investigate the association between climate and atopic diseases using worldwide data from 146 centres of the International Study of Asthma and Allergies in Childhood (ISAAC). Methods: Between 1992 and 1996, each centre studied random samples of children aged 13–14 and 6–7 years (approx. 3000 per age group and centre) using standardised written and video questionnaires on symptoms of asthma, allergic rhinoconjunctivitis, and atopic eczema during the past 12 months. Data on long term climatic conditions in the centres were abstracted from one standardised source, and mixed linear regression models calculated to take the clustering of centres within countries into account. Results: In Western Europe (57 centres in 12 countries), the prevalence of asthma symptoms, assessed by written questionnaire, increased by 2.7% (95% CI 1.0% to 4.5%) with an increase in the estimated annual mean of indoor relative humidity of 10%. Similar associations were seen for the video questionnaire and the younger age group. Altitude and the annual variation of temperature and relative humidity outdoors were negatively associated with asthma symptoms. The prevalence of eczema symptoms correlated with latitude (positively) and mean annual outdoor temperature (negatively). Conclusions: Results suggest that climate may affect the prevalence of asthma and atopic eczema in children. PMID:15208377

  14. Multiple grass mixes as opposed to single grasses for allergen immunotherapy in allergic rhinitis.

    2013-11-01

    Grass pollen allergy affects approximately 40% of allergic patients. Subcutaneous allergen immunotherapy (SCIT) is the only allergen-specific and disease-modifying treatment available. Currently available therapeutic vaccines for the treatment of grass pollen allergy are based on natural grass pollen extracts which are either made from pollen of one cross-reactive grass species or from several related grass species. Clinical studies have shown that SCIT performed with timothy grass pollen extract is effective for the treatment of grass pollen allergy. Moreover, it has been demonstrated that recombinant timothy grass pollen allergens contain the majority of relevant epitopes and can be used for SCIT in clinical trials. However, recent in vitro studies have suggested that mixes consisting of allergen extracts from several related grass species may have advantages for SCIT over single allergen extracts. Here, we review current knowledge regarding the disease-relevant allergens in grass pollen allergy, available clinical studies comparing SCIT with allergen extracts from timothy grass or from mixes of several related grass species of the Pooideae subfamily, in vitro cross-reactivity studies performed with natural allergen extracts and recombinant allergens and SCIT studies performed with recombinant timothy grass pollen allergens. In vitro and clinical studies performed with natural allergen extracts reveal no relevant advantages of using multiple grass mixes as opposed to single grass pollen extracts. Several studies analysing the molecular composition of natural allergen extracts and the molecular profile of patients' immune responses after SCIT with allergen extracts indicate that the major limitation for the production of a high quality grass pollen vaccine resides in intrinsic features of natural allergen extracts which can only be overcome with recombinant allergen-based technologies.

    Objectives. The current study aimed to compare the efficacy and safety of a classical anti-inflammatory beclomethasone nasal spray in comparison to a physic-chemical stabilizing ectoine containing nasal spray in the treatment of allergic rhinitis. Design and Methods. This was a noninterventional, open-label, observational trial investigating the effects of beclomethasone or ectoine nasal spray on nasal symptoms and quality of life. Over a period of 14 days, patients were asked to daily document their symptoms. Efficacy and tolerability were assessed by both physicians and patients. Results. Both treatments resulted in a significant decrease of TNSS values. An equivalence test could not confirm the noninferiority of ectoine treatment in comparison with beclomethasone treatment. Although clear symptom reduction was achieved with the ectoine products, the efficacy judgment showed possible advantages for the beclomethasone group. Importantly, tolerability results were comparably good in both groups, and a very low number of adverse events supported this observation. Both treatments resulted in a clear improvement in the quality of life as assessed by a questionnaire answered at the beginning and at the end of the trial. Conclusion. Taken together, it was shown that allergic rhinitis can be safely and successfully treated with beclomethasone and also efficacy and safety were shown for ectoine nasal spray.

    Two foundational methods for estimating the total economic burden of disease are cost of illness (COI) and willingness to pay (WTP). WTP measures the full cost to society, but WTP estimates are difficult to compute and rarely available. COI methods are more often used but less likely to reflect full costs. This paper attempts to estimate the full economic cost (2014$) of illnesses resulting from exposure to dampness and mold using COI methods and WTP where the data is available. A limited sensitivity analysis of alternative methods and assumptions demonstrates a wide potential range of estimates. In the final estimates, the total annual cost to society attributable to dampness and mold is estimated to be $3.7 (2.3-4.7) billion for allergic rhinitis, $1.9 (1.1-2.3) billion for acute bronchitis, $15.1 (9.4-20.6) billion for asthma morbidity, and $1.7 (0.4-4.5) billion for asthma mortality. The corresponding costs from all causes, not limited to dampness and mold, using the same approach would be $24.8 billion for allergic rhinitis, $13.5 billion for acute bronchitis, $94.5 billion for asthma morbidity, and $10.8 billion for asthma mortality.

    Rhinitis is a common global disorder that impacts on the quality of life of the sufferer and caregivers. Treatment for pediatric rhinitis is empirical and does not include a detailed history of the allergy triggers or allergy testing. Thus, allergen avoidance advice is not tailored to the child's sensitivities, which may result in adenoid hypertrophy. However, infant onset rhinitis, especially its relationship with respiratory viruses, remains to be further clarified. Rhinitis basically involves inflammation of the upper nasal lining, presenting typically with symptoms of runny nose (rhinorrhea), nasal blockage, and/or sneezing. While not typically fatal, it does impose significant health, psychological, and monetary burden to its sufferers, and is thus considered a global health problem. Previous findings showed that immunotherapy had significant clinical efficacy in children with allergic rhinitis. The present review article aims to highlight recent perspectives pertaining to the rhinitis risk factors especially in pediatric patients. PMID:27698737

    Rhinitis, a condition involving inflammation and irritation of the nasal membranes, is a common condition that can be allergic or non-allergic in origin. Pre-existing rhinitis can worsen during pregnancy, and new rhinitis can occur. Rhinitis has a significant effect on quality of life. Where rhinitis co-exists with asthma, it is a major risk factor for poor asthma control, which can have adverse effects on fetal development during pregnancy. Prescribing any drug treatment during pregnancy carries risks that must balance the benefits of symptom control with pregnancy outcome. Attaining control of rhinitis during pregnancy requires appropriate drug treatment, alongside careful patient education, monitoring and support. This article outlines the safety profile of common treatments used for rhinitis in women who are pregnant and/or breastfeeding. The aim is to aid the nurse in providing safe, effective treatment and information, thereby allowing patients to make informed decisions.

Methods: In this multi-centre, open-label trial, 87 paediatric Japanese patients with PAR received montelukast 4 mg oral granules (OG) for 4 weeks (1–5-year-olds, N = 15), 4 mg OG for 12 weeks (1–5-year-olds, N = 36), 5 mg chewable tablets (CT) for 12 weeks (6–9-year-olds, N = 18), or 5 mg CT for12 weeks (10–15-year-olds, N = 18). Clinical exams and laboratory assessments were conducted at study visits, and adverse events (AE) were monitored throughout the study up to 14 days after the last visit. Population pharmacokinetic approach was used to estimate AUC0–∞, Cmax, Tmax and apparent elimination half-life in each age group. Efficacy was assessed based on global evaluations by the subject’s caregiver. Results: There were no serious AEs and one discontinuation due to an AE. The most common AEs in any of the treatment groups were nasopharyngitis, pharyngitis, and acute sinusitis. Montelukast exposure (AUC0–∞) was similar in the 1–5-year-old group and the 6–9-year-old group, but 19% lower in the 10–15-year-old group. Among all patients, the total proportion of patients whose global evaluation was “very much better” was 5.7% (week 2), 11.5% (week 4), and 16.9% (week 12) reflecting improvement in symptoms over time. Conclusion: Montelukast was generally well tolerated in Japanese children with PAR. AUC0–∞was similar in 1–5 and 6–9-year-olds, while a lower exposure was observed in the 10–15-year-old group likely due to differences in bodyweight. The exposure in Japanese paediatric patients was generally consistent with that in non-Japanese paediatric and adult patients. As assessed by the patients’ caregivers, montelukast also

    Background In surveys of children with allergic rhinitis (AR), nasal congestion has been identified as the most frequently experienced and bothersome symptom. This analysis was conducted to investigate the effect of mometasone furoate nasal spray (MFNS) on congestion in children with AR. Methods Two multicenter, double-blind, placebo-controlled studies randomly assigned children to MFNS 100 μg or placebo, 1 spray/nostril QD for 4 weeks (Study 1: ages 6–11 years with seasonal AR [SAR] ≥1 year; Study 2: ages 3–11 years with perennial AR [PAR] ≥1 year). Least square (LS) means were obtained from an ANCOVA model with treatment and study center effects, with baseline score as a covariate. We conducted post hoc evaluation of changes from baseline in AM/PM PRIOR (average of reflective AM and PM scores) nasal congestion (0=none to 3=severe). Results Study 1: MFNS (n=134) reduced congestion significantly more than placebo (n=135) on day 2 (P=.004) and on 23/29 days (P≤.037). Change from baseline was −0.53 and −0.28 for MFNS and placebo (P<.001) over days 1–15 and −0.64 and −0.38 for MFNS and placebo (P<.001) over days 1–29. Study 2: MFNS (n=185) reduced congestion significantly more than placebo (n=189) on day 3 (P=.015) and on 22/29 days (P≤.047). Change from baseline was −0.56 and −0.36 for MFNS and placebo (P<.001) over days 1–15 and −0.64 and −0.45 for MFNS and placebo (P<.001) over days 1–29. MFNS was well tolerated, with no unusual or unexpected adverse events. Conclusion MFNS effectively relieved nasal congestion and was well tolerated in children with SAR or PAR. PMID:23663488

    Fab fragments (Fabs) have the ability to bind to specific antigens but lack the Fc portion for binding to receptors on immune and inflammatory cells that play a critical role in allergic diseases. In the present study, we investigated whether Fabs of an allergen-specific IgG1 monoclonal antibody (mAb) inhibited allergic rhinitis in mice. BALB/c mice sensitized by intraperitoneal injections of ovalbumin (OVA) plus alum on days 0 and 14 were intranasally challenged with OVA on days 28-30, and 35. Fabs prepared by the digestion of an anti-OVA IgG1 mAb (O1-10) with papain were also intranasally administered 15min before each OVA challenge. The results showed that treatment with O1-10 Fabs significantly suppressed the sneezing frequency, associated with decrease of OVA-specific IgE in the serum and infiltration by mast cells in the nasal mucosa seen following the fourth antigenic challenge; additionally, the level of mouse mast cell protease-1, a marker of mast cell activation, in serum was decreased. Furthermore, infiltration of eosinophils and goblet cell hyperplasia in the nasal mucosa at the fourth challenge were inhibited by treatment with O1-10 Fabs. In conclusion, these results suggest that intranasal exposure to Fabs of a pathogenic antigen-specific IgG1 mAb may be effective in regulating allergic rhinitis through allergen capture by Fabs in the nasal mucosa before the interaction of the intact antibody and allergen.

  5. Trends in prevalence of allergic rhinitis and correlation with pollen counts in Switzerland

    In recent decades, a large number of epidemiological studies investigating the change of prevalence of hay fever showed an increase in the occurrence of this disease. However, other studies carried out in the 1990s yielded contradictory results. Many environmental factors have been hypothesized to contribute to the increasing hay fever rate, including both indoor and ambient air pollution, reduced exposure to microbial stimulation and changes in diets. However, the observed increase has not convincingly been explained by any of these factors and there is limited evidence of changes in exposure to these risk factors over time. Additionally, recent studies show that no further increase in asthma, hay fever and atopic sensitisation in adolescents and adults has been observed during the 1990s and the beginning of the new century. As the pattern of pollen counts has changed over the years, partly due to the global warming but also as a consequence of a change in the use of land, the changing prevalence of hay fever might partly be driven by this different pollen exposure. Epidemiological data for hay fever in Switzerland are available from 1926 until 2000 (with large gaps between 1926 and 1958 and 1958 to 1986) whereas pollen data are available from 1969 until the present. This allows an investigation as to whether these data are correlated provided the same time spans are compared. It would also be feasible to correlate the pollen data with meteorological data which, however, is not the subject of our investigation. Our study focuses on analyzing time series of pollen counts and of pollen season lengths in order to identify their trends, and to ascertain whether there is a relationship between these trends and the changes in the hay fever prevalence. It is shown in this paper that the pollen exposure has been decreasing in Basel since the beginning of the 1990s whereas the rate of the hay fever prevalence in Switzerland remained approximately unchanged in this period

    Background The aim of this population-based study was to investigate the risk of developing noninfectious rhinitis (NIR) in subjects with chronic obstructive pulmonary disease (COPD). Materials and methods This is a longitudinal population-based study comprising 3,612 randomly selected subjects from Gothenburg, Sweden, aged 25–75 years. Lung function was measured at baseline with spirometry and the included subjects answered a questionnaire on respiratory symptoms. At follow-up, the subjects answered a questionnaire with a response rate of 87%. NIR was defined as symptoms of nasal obstruction, nasal secretion, and/or sneezing attacks without having a cold, during the last 5 years. COPD was defined as a spirometry ratio of forced expiratory volume in 1 second divided by forced vital capacity (FEV1/FVC) <0.7. Subjects who reported asthma and NIR at baseline were excluded from the study. The odds ratios for developing NIR (ie, new-onset NIR) in relation to age, gender, body mass index, COPD, smoking, and atopy were calculated. Results In subjects with COPD, the 5-year incidence of NIR was significantly increased (10.8% vs 7.4%, P=0.005) and was higher among subjects aged >40 years. Smoking, atopy, and occupational exposure to gas, fumes, or dust were also associated with new-onset NIR. COPD, smoking, and atopy remained individual risk factors for new-onset NIR in the logistic regression analysis. Conclusions This longitudinal population-based study of a large cohort showed that COPD is a risk factor for developing NIR. Smoking and atopy are also risk factors for NIR. The results indicate that there is a link present between upper and lower respiratory inflammation in NIR and COPD. PMID:27799760

  7. Revisiting the roles of mast cells in allergic rhinitis and its relation to local IgE synthesis.

    Mast cells are important effector cells in the immediate-phase allergic reaction. However, in recent years much evidence has accumulated on the versatile role of mast cells in allergic inflammation. The present article is an overview of the roles of mast cells in allergic inflammation, especially in light of the local production of IgE and the IgE-IgE receptor network. Although both nasal mast cells (NMC) and T cells in allergic rhinitics are important sources of Th2-type cytokines like IL-4 and IL-13, and can induce IgE synthesis, we report here that antigen-activated NMC can secrete greater levels of IL-4/IL-13 and induce increased levels of IgE synthesis than antigen-activated nasal T cells. Furthermore, IgE production can occur locally in the nasal mucosa (target organ) and IgE itself can enhance the Fc epsilon RI expression and subsequent mediator release from NMC, thus contributing to the perpetuation of on-going allergic inflammation. Again, mast cells can contribute to the late-phase allergic reaction not only via the upregulation of adhesion molecules like VCAM-1, but also through the interactions of NMC with the extracellular matrix proteins, and interaction of NMC with nasal epithelial cells (NEC). Thus, it is increasingly evident that mast cells are not only important for the genesis of the allergic reaction, but also contribute to the late-phase allergic reaction and on-going allergic inflammation.

    Occupational rhinitis is characterized by nasal congestion, rhinorrhea, nasal itching, and/or sneezing that occur secondary to exposures in the workplace. This disease can be classified into allergic or nonallergic subgroups based upon the underlying disease pathogenesis as well as the type of causative agent. While the true prevalence of occupational rhinitis is unknown, there are certain professions and occupational exposures that place workers at a higher risk for developing the disease. Additionally, occupational rhinitis can be associated with occupational asthma and upper airway symptoms may precede those of the lower respiratory tract. Taken together, occupational rhinitis is an important disease for study given its medical as well as socioeconomic implications. This review will focus on the classification of occupational rhinitis as well the prevalence, diagnosis, and treatment strategies.

    In patients with allergic rhinitis (AR), the nasal provocation test (NPT) is the standard procedure to evaluate the clinical response of the nasal mucosa to allergens with a high specificity and sensitivity. In AR, it is the only test that really measures the response of the diseased mucosa to allergens while skin prick test and serum IgE confirm the clinical suspicion of sensitization. Moreover, it is of special relevance in the detection of patients with Local Allergic Rhinitis (LAR), where general sensitization cannot be measured. For the evaluation of therapeutic interventions, NPT has been used for the clinical monitoring of antiallergic drugs and allergen specific immunotherapy. Legislation within the European Union (EU) defines allergens used for diagnostic tests like NPT to be medicinal products according to Directive 2001/83 EC, but national law is considering these products to be medicinal devices in a number of EU countries. Thus, NPT products are governed by different legislations and therefore standards throughout the EU. In consequence, allergens used for diagnostic purposes need different registrations and Marketing Authorization by national authorities. After a transition period, regulations of EU Directives are to be implemented in national law by all member states. At the moment, most EU countries have not fully implemented these Directives, however, it can be expected that most countries will implement it and enforce their rules within the next years. This development has a tremendous impact on the availability of diagnostic allergens for NPT in Europe and will make make nasal provocation testing very difficult if not impossible. We describe the current situation of diagnostic allergens under the special legislative conditions in the EU with special focus on allergen products used for NPT and the consequences for the diagnosis of AR and LAR.

  10. Measuring outcomes in allergic rhinitis: psychometric characteristics of a Spanish version of the congestion quantifier seven-item test (CQ7)

    2011-01-01

    Background No control tools for nasal congestion (NC) are currently available in Spanish. This study aimed to adapt and validate the Congestion Quantifier Seven Item Test (CQ7) for Spain. Methods CQ7 was adapted from English following international guidelines. The instrument was validated in an observational, prospective study in allergic rhinitis patients with NC (N = 166) and a control group without NC (N = 35). Participants completed the CQ7, MOS sleep questionnaire, and a measure of psychological well-being (PGWBI). Clinical data included NC severity rating, acoustic rhinometry, and total symptom score (TSS). Internal consistency was assessed using Cronbach's alpha and test-retest reliability using the intraclass correlation coefficient (ICC). Construct validity was tested by examining correlations with other outcome measures and ability to discriminate between groups classified by NC severity. Sensitivity and specificity were assessed using Area under the Receiver Operating Curve (AUC) and responsiveness over time using effect sizes (ES). Results Cronbach's alpha for the CQ7 was 0.92, and the ICC was 0.81, indicating good reliability. CQ7 correlated most strongly with the TSS (r = 0.60, p < 0.01), the PGWBI general health dimension (r = 0.56, p < 0.01), and the MOS Sleep scale 'sleep short of breath' dimension (r = 0.49, p < 0.01). Correlations with acoustic rhinometry were generally low. The instrument discriminated well between NC severity groups (ES 0.33-2.07) and AUC was 0.93, indicating excellent sensitivity and specificity. The measure was responsive to change (ES = 1.1) in patients reporting improvement in NC. Conclusions The Spanish version of the CQ7 is appropriate for detecting, measuring, and monitoring NC in allergic rhinitis patients. PMID:21392375

    Rhinitis is a common presentation in childhood. Acute virally induced rhinitis is generally self-limiting and usually does not require medical attention. Whilst allergic rhinitis is the focus of the paediatric allergist, the presentation of other diseases or comorbidities that can complicate or mimic allergic rhinitis needs to be considered. Effects on the child's quality of life also need to be addressed. Rhinitis can be associated with asthma and other significant comorbidities: importantly, non-allergic rhinitis can sometimes be a consequence of systemic immune impairment. The diagnosis of rhinitis is based on clinical findings with directed investigations. Nasal nitric oxide measurement is an emerging diagnostic tool and helpful particularly in relation to evaluating the differential diagnosis in more difficult rhinitis. Successfully identifying the cause of rhinitis in childhood and associated comorbidities can ensure that the patient is successfully treated as described in the recently published EAACI Pediatric Rhinitis Position Paper.

    OBJECTIVE: To determine the in vivo allergenicity of two grades of peanut oil for a large group of subjects with proved allergy to peanuts. DESIGN: Double blind, crossover food challenge with crude peanut oil and refined peanut oil. SETTING: Dedicated clinical investigation unit in a university hospital. SUBJECTS: 60 subjects allergic to peanuts; allergy was confirmed by challenge tests. OUTCOME MEASURES: Allergic reaction to the tested peanut oils. RESULTS: None of the 60 subjects reacted to the refined oil; six (10%) reacted to the crude oil. Supervised peanut challenge caused considerably less severe reactions than subjects had reported previously. CONCLUSIONS: Crude peanut oil caused allergic reactions in 10% of allergic subjects studied and should continue to be avoided. Refined peanut oil did not pose a risk to any of the subjects. It would be reasonable to recommend a change in labelling to distinguish refined from crude peanut oil. PMID:9133891

    Allergic rhinitis is a common health problem in both children and adults. The number of patients allergic to ragweed (Ambrosia artemisiifolia) is on the rise throughout Europe, having a significant negative impact on the patients' and their family's quality of life. Allergen-specific immunotherapy (AIT) has disease-modifying effects and can induce immune tolerance to allergens. Both subcutaneous immunotherapy and sublingual immunotherapy with ragweed extracts/preparations have clear positive clinical efficacy, especially over pharmacological treatment, even years after the treatment has ended. AIT also has very good safety profiles with extremely rare side effects, and the extracts/preparations used in AIT are commonly well tolerated by patients. However, patient adherence to treatment with AIT seems to be quite low, mostly due to the fact that treatment with AIT is relatively time-demanding and, moreover, due to patients not receiving adequate information and education about the treatment before it starts. AIT is undergoing innovations and improvements in clinical efficacy, safety and patient adherence, especially with new approaches using new adjuvants, recombinant or modified allergens, synthetic peptides, novel routes of administration (epidermal or intralymphatic), and new protocols, which might make AIT more acceptable for a wider range of patients and novel indications. Patient education and support (eg, recall systems) is one of the most important goals for AIT in the future, to further enhance treatment success.

    Under the broad heading of "vasomotor" rhinitis two big groups can be distinguished: allergic rhinitis (IgE-mediated), and nonallergic rhinitis. Since they are two separate nosological entities, they can co-exist in the same patient, classifying themselves in the group of "overlapped" rhinitis (OR). Although not absolutely rare (indeed it is estimated a 15-20% incidence among all vasomotor rhinopathies), this condition is not investigated and diagnosed, with significant implications in the clinical-diagnostic and therapeutic field.

    The objective of this study was to evaluate the prevalence of asthma, allergic rhinitis, and atopic dermatitis, as well as the risk factors of wheezing among young adults in the Korean military. Young military conscripts in five areas completed a modified International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. For subjects with current wheeze in one sample area, baseline spirometry and bronchodilator response were measured. For subjects without a significant response to bronchodilator (improvement in FEV1 of more than 200 mL and 12%), methacholine challenge tests (MCT) were also performed. Of 3,359 subjects that completed the questionnaire, 354 (10.5%) had current wheeze, 471 (14.0%) had current allergic rhinitis, and 326 (9.7%) had current eczema. Current wheeze was associated with family history of allergic disease, overweight, current smoking, allergic rhinitis, and atopic dermatitis. Of 36 subjects with current wheeze who underwent PFT with or without MCT in the Anyang area, 24 (66.7%) were confirmed to have current asthma. In conclusion, the prevalence of allergic disease in young adults of Korean military is not low, and the risk factors of wheezing include family history of allergic disease, overweight, current smoking, allergic rhinitis, and atopic dermatitis.

    The aim of this study is to compare the efficacy and safety of a once-daily loratadine-pseudoephedrine sustained release tablet with that of a twice-daily loratadine-pseudoephedrine in the treatment of patients with allergic rhinitis. Forty-eight subjects were randomized into either the treatment or control group. The efficacy endpoint was assessed by total symptom scores (TSS). And the results were analyzed by non-inferiority testing and t-tests. Non-inferiority testing of the once daily loratadine 10 mg-pseudoephedrine 240 mg sustained release tablets to the twice-daily loratadine 5 mg-pseudoephedrine 120 mg combination tablets was not supported by statistical significance. However, both the treatment and control groups showed a significant reduction from the baseline in TSS (P < 0.05), and the difference between groups did not reach statistical significance (P > 0.05). In conclusion, once-daily and twice-daily preparations of loratadine-pseudoephedrine were comparable in efficacy and safety in the treatment of allergic rhinitis.

    Pharmacotherapy is widely used to manage allergic rhinitis (AR), but often does not adequately control symptoms. Allergy immunotherapy (AIT) should be considered for patients who are not adequately controlled on symptomatic treatment. AIT is gaining attention because of its potential to improve symptom relief and quality of life, and to provide sustained effect after the end of treatment by modifying the course of disease. However, evidence of efficacy needs to be shown for each individual AIT product, based on state-of-the-art studies. The majority of products cannot truly claim efficacy and disease-modifying potential, as evidence of such an effect from robust randomized double-blind, placebo-controlled long-term trials is lacking. The potential of a specific immunotherapy product should be evaluated against four levels of benefit defined by the European Medicines Agency (EMA) guideline on clinical development of AIT products. These clearly distinguish between efficacy of symptom relief in the first year, efficacy over 2-3 treatment years, sustained efficacy and disease modification treatment ends, and sustained absence of allergic symptoms in posttreatment years. The clinician's choice of a specific AIT product should take the level of evidence and risk/benefit into account, as the patient's quality of life and the product's potential long-term effect are important components of its overall cost-effectiveness. Without evidence of maintained clinical benefit and disease modification after the end of treatment, claims of long-term economic benefit of specific AIT products cannot be justified. This paper discusses the evidence that is essential for critical evaluation of product claims in health economic analysis comparing AIT products.

    One-third of the Dutch population suffers from allergic rhinitis, including hay fever. In this study, a 5-day-ahead hay fever forecast was developed and validated for grass pollen allergic patients in the Netherlands. Using multiple regression analysis, a two-step pollen and hay fever symptom prediction model was developed using actual and forecasted weather parameters, grass pollen data and patient symptom diaries. Therefore, 80 patients with a grass pollen allergy rated the severity of their hay fever symptoms during the grass pollen season in 2007 and 2008. First, a grass pollen forecast model was developed using the following predictors: (1) daily means of grass pollen counts of the previous 10 years; (2) grass pollen counts of the previous 2-week period of the current year; and (3) maximum, minimum and mean temperature (R (2)=0.76). The second modeling step concerned the forecasting of hay fever symptom severity and included the following predictors: (1) forecasted grass pollen counts; (2) day number of the year; (3) moving average of the grass pollen counts of the previous 2 week-periods; and (4) maximum and mean temperatures (R (2)=0.81). Since the daily hay fever forecast is reported in three categories (low-, medium- and high symptom risk), we assessed the agreement between the observed and the 1- to 5-day-ahead predicted risk categories by kappa, which ranged from 65 % to 77 %. These results indicate that a model based on forecasted temperature and grass pollen counts performs well in predicting symptoms of hay fever up to 5 days ahead.

    In view of the controversies surrounding the angiotensin-converting enzyme (ACE)-allergic rhinitis (AR) association, a systematic review and meta-analysis of the ACE genetic association studies of AR was performed in Chinese populations. PubMed, Springer Link, OvidSP, Chinese biomedical database, Chinese national knowledge infrastructure, Chinese VIP and Wanfang databases were searched for related studies. A total of 4 studies including 415 AR patients and 309 controls were involved in this meta-analysis. Overall, significant association was found between ACE I/D polymorphism and AR risk when all studies in Chinese populations pooled into the meta-analysis (allele, OR 1.50, 95 % CI 1.19-1.90; homozygous, OR 2.59, 95 % CI 1.52-4.41, recessive, OR 2.05, 95 % CI 1.27-3.32). In the subgroup analysis by ethnicity, ACE I/D polymorphism was associated with significant elevated risks of AR in Chinese Han under homozygous and recessive models (homozygous, OR 4.36, 95 % CI 1.76-10.82, recessive, OR 2.51, 95 % CI 1.18-5.34). In conclusion, this meta-analysis provides the evidence that ACE I/D polymorphism may contribute to the AR development in Chinese populations and studies with large sample size and wider spectrum of population are warranted to verify this finding.

    Objective: To compare the efficacy, safety, and cost-effectiveness of rupatadine and olopatadine in patients of allergic rhinitis (AR). Materials and Methods: A 2-week, single-centered, randomized, double-blind, parallel group comparative clinical study was conducted on patients with AR. Following inclusion and exclusion criteria, 67 patients were recruited and randomized to two treatment groups and received the respective drugs for 2 weeks. At follow-up, parameters assessed were total nasal symptom score (TNSS), change in total and differential count of eosinophil. Results: In olopatadine group, there was a significantly higher reduction in TNSS (P < 0.05) than that of rupatadine. Both the drugs significantly reduced the absolute eosinophil count, but olopatadine (P < 0.001) was found to be superior. The incidence of adverse effects was found to be less in olopatadine group when compared with rupatadine group. Conclusion: Olopatadine is a better choice in AR in comparison to rupatadine due to its better efficacy and safety profile. PMID:28163538

    Nonallergic rhinitis is a common disease that affects many Americans. It is characterized by nasal symptoms of congestion and rhinorrhea without evidence of allergic sensitization. The pathophysiology of the disease has not been studied extensively. In the following article, the author concentrates on summarizing the available information related to cellular inflammation and neurogenic mechanisms in patients with nonallergic rhinitis. The author also explores nasal reactivity to various stimuli in these patients.

    Non-allergic rhinitis with eosinophilia syndrome (NARES) is an eosinophilic inflammation of the nasal mucosa without evidence of an allergy or other nasal pathologies. Patients complain about perennial symptoms like nasal obstruction, rhinorrhea, itchiness and sneezing of the nose sometimes accompanied by hyposmia. The aim of the study was to better characterize NARES patients using immunoassay-biochip technology to examine serum and nasal secretion. Sera and nasal secretion of patients with NARES (perennial nasal symptoms, no evidence of acute or chronic rhinosinusitis with or without polyps, negative SX1-Screening test and/or negative skin prick test, eosinophilic cationic protein in nasal secretion >200 ng/ml) were tested by immunoassay-biochip technology (ImmunoCAP(®) ISAC, Phadia). 112 different allergen components from 51 allergen sources were tested on the chip. Furthermore, serum and nasal secretion were tested for specific IgE to Staphylococcus aureus enterotoxin TSST-1 by fluorescence-enzyme-immunoassay (UniCAP(®), Phadia). Unrecognized systemic sensitization could be ruled out by negative ISAC results in sera of all patients. Testing of nasal secretion for allergen-specific IgE by ISAC chip technology was negative as well in all cases. In one patient, a systemic sensitization to Staphylococcus aureus superantigen TSST-1 was detectable but no allergen-specific IgE to TSST-1 was measurable in nasal secretion of any patient. The results demonstrate that NARES is not associated with local allergy (entopy) nor with a local inflammation driven by Staphylococcus aureus enterotoxin TSST-1. Further studies are necessary to better understand the underlying mechanisms of NARES.

    Objectives: Allergic rhinitis (AR) is a global health problem. Almost 10%–25% of population worldwide is affected by AR. Oral/intranasal H1-antihistamine, decongestants, leukotriene receptor antagonists, and intranasal corticosteroids are the pillars in the management of AR. The combination therapy of montelukast with antihistaminic provides enhancing and complimentary effects, thereby reducing the symptoms effectively, but there are scanty data regarding the comparisons of combinations. Therefore, we aimed to compare the efficacy, safety, and cost-effectiveness of montelukast-levocetirizine and montelukast-fexofenadine combination in patients of AR. Materials and Methods: Seventy patients with AR participated in a prospective, randomized, double-blind, parallel, active-controlled, comparative 4-week trial. The patients between the age group of 18–65 years of either gender having moderate-severe intermittent or mild persistent AR were included in the study. The study inclusion criteria required the patients with total nasal symptom score (TNSS) of 5 or higher. The patients were randomly divided into two treatment groups with montelukast-levocetirizine (10 mg and 5 mg) in one group and montelukast-fexofenadine (10 mg and 120 mg) in another group. TNSS parameter was the main effectiveness parameter. Results: Evaluation of TNSS revealed significant difference (P < 0.05) when compared from baseline to 4th week in both groups. The mean change of TNSS, i.e., 9.46 was significant (P < 0.05) in montelukast-fexofenadine group. The cost-effectiveness ratio was less in montelukast-levocetirizine group than in montelukast-fexofenadine group. Conclusion: The decrease in TNSS was more in montelukast-fexofenadine group, but the cost-effectiveness is more with montelukast-levocetirizine combination. PMID:28066101

    Cocamidopropyl betaine (CAPB) has been identified as a cause of contact allergy in personal care products. Furthermore, it has been suggested that chemicals responsible are impurities, especially dimethylaminopropylamine (DMAPA). However, skin contact concentrations with these impurities, especially DMAPA, are very low. The aim of the study was to analyse whether subjects with previous positive patch tests to CAPB would react in provocative use tests of a product containing CAPB. 10 individuals with a clinical history of contact allergy to CAPB (by positive patch test and history) took part in a ROAT which used a CAPB-based shower gel at 25% (DMAPA concentration < 1 ppm). None of the subjects showed positive allergic reactions. 1 of the test subjects did experience a flare of atopic dermatitis at the treatment site. Later, all 10 subjects were patch tested to 3 different concentrations of CAPB and DMAPA (0.1%, 0.3%, 1%) to verify the threshold that was capable of inducing a positive test reaction. 5/10 showed clear + reactions to 1% CAPB (typically at D3), whilst a further 3 gave marginal and/or irritant reactions. Only 1 of the subjects showed an allergic reaction to DMAPA. Finally, in uncontrolled use testing with the shower gel, none of the test subjects reported any adverse skin reactions. Thus, the study confirmed that CAPB-sensitive individuals can use a CAPB-based rinse-off product without the risk of experiencing an allergic reaction to CAPB.

  7. Protocol for a double-blind randomised controlled trial of low dose intradermal grass pollen immunotherapy versus a histamine control on symptoms and medication use in adults with seasonal allergic rhinitis (PollenLITE)

    PubMed Central

    2013-01-01

    Background Subcutaneous immunotherapy with high dose grass pollen (typically microgram quantities) was first described over 100 years ago. This treatment suppresses allergen-induced cutaneous late responses, with lesser effects on early responses. We previously reported that repeated 2-weekly intradermal injections of grass pollen - containing approximately 7 ng of major allergen Phl p 5 – led to a progressive suppression of the allergen-induced cutaneous response, and that by the sixth injection, this was inhibited by over 90%. The purpose of this trial is to investigate the clinical efficacy of intradermal desensitisation with low doses (i.e. nanogram quantities) of grass pollen allergen for seasonal allergic rhinitis. Methods/design The Pollen Low dose Intradermal therapy Evaluation (PollenLITE) is a single centre double-blind randomised parallel group controlled trial of the efficacy and safety of intradermal grass pollen injections plus standard treatment, versus histamine injections plus standard treatment, in adults with moderate-severe grass pollen-induced allergic rhinitis (‘summer hay fever’). A minimum of ninety adults with a history of moderate-severe persistent allergic rhinitis during the UK grass pollen season will be randomised into two equal groups to receive 7 or 8 intradermal injections of grass pollen extract (containing approximately 7 ng of major allergen Phl p 5) or histamine, before the grass pollen season. In the summer, participants will score their symptoms, medication requirements, visual analogue scores, and complete EuroQOL (EQ-5D-5 L) and mini Rhinoconjunctivitis Quality of Life Questionnaires. Global assessments will also be recorded at the end of the pollen season. Blood samples will be collected from all participants for mechanistic immune assays. Skin punch biopsies will also be collected in 40 participants selected at random from intradermal injection sites after the grass pollen season for mechanistic assays. Finally

    Chemokines have chemotactic properties on leukocyte subsets whose modulation plays a pivotal role in allergic inflammatory processes. Our present study was designed to investigate the anti-allergic and anti-inflammatory properties of desloratadine citrate disodium injection (DLC) and elucidate the molecular mechanisms of its anti-inflammatory properties. The anti-allergic effects of DLC were evaluated based on allergic symptoms, serological marker production and histological changes of the nasal mucosa in guinea pigs model of allergic rhinitis. The anti-inflammatory properties and molecular mechanisms of DLC were explored by studying the regulation of a set of chemokines and extracellular signal-regulated kinase (ERK)1/2 and nuclear factor-kappa B (NF-κB) pathways, after DLC treatment in guinea pigs model of allergic rhinitis in vivo and histamine-activated human nasal epithelial cells (HNECs) in vitro. In vivo model in guinea pigs, DLC alleviated the rhinitis symptoms, inhibited inflammatory cells infiltration in nasal lavage fluid (NLF) and histamine, monocyte chemotactic protein (MCP)-1, regulated on activation normal T cell expressed, and presumably secreted (RANTEs) and interleukin (IL)-8 release in sera and P-ERK1/2 and NF-κB activation in nasal mucosa. In vitro, DLC markedly inhibited histamine-induced production of MCP-1, RANTEs and IL-8 and suppressed c-Raf, mitogen-activated protein/extracellular signal-regulated kinase kinase (MEK) and ERK1/2 activation in HNECs. These results provide evidence that DLC possesses potent anti-allergic and anti-inflammatory properties. The mechanism of action underlying DLC in allergic inflammation appears to be inhibition of the phosphorylation of ERK1/2, in addition to blocking of the NF-κB pathway.

    We have previously demonstrated that anti-IL-1β immunoglobulin yolk(IgY) inhibits pathological responses in allergic asthma guinea pigs induced by ovalbumin(OVA). This study aims to determine whether the combined blockade of IL-1β and TNF-α can more effectively inhibit allergic inflammation in allergic rhinitis(AR) guinea pigs induced by OVA. Healthy guinea pigs treated with saline were used as the healthy control. The AR guinea pigs induced by OVA were randomly divided into (1) the AR model group containing negative control animals treated with intranasal saline; (2) the 0.1% non-specific IgY treatment group treated with non-specific IgY; (3) the 0.1% anti-TNF-α IgY treatment group treated with 0.1% anti-TNF-α IgY; (4) the 0.1% anti-IL-1β IgY treatment group treated with 0.1% anti-IL-1β IgY; (5) the 0.1% combined anti-IL-1β IgY and anti-TNF-α IgY treatment group treated with 0.1% combined anti-IL-1β IgY and anti-TNF-α IgY; and (6) the fluticasone propionate treatment group treated with fluticasone propionate. Cytokines were measured using an enzyme-linked immunosorbent assay. The results showed that IL-1β, IL-5, IL-9, IL-13, IL-18, IL-22, IL-33, TNF-α, TGF-β1 and OVA-specific IgE levels in the peripheral blood (PB) and nasal lavage fluid (NLF) significantly decreased at 2h, 4h or 8h in the 0.1% combined anti-IL-1β IgY and anti-TNF-α IgY treatment group compared to the AR model group and the 0.1% non-specific IgY treatment group (P<0.05). The data suggest that blockade of IL-1β and TNF-α by intranasal instillation of combined anti-IL-1β IgY and anti-TNF-α IgY could be a potential alternative strategy for preventing and treating allergic rhinitis.

    The present study was undertaken to describe the pharmacokinetics of a new solution-based intranasal triamcinolone acetonideformulation (Tri-Nasal) in patients with perennial allergic rhinitis and to use a pharmacokinetic/pharmacodynamic (PK/PD) simulation approach to compare the potential effects on plasma cortisol with that of an aqueous suspension-based nasal triamcinolone acetonide formulation (Nasacort AQ). Data from an open-label, randomized, three-way crossover study in patients with perennial allergic rhinitis receiving three doses (100, 200, and 400 microg) of a nasal solution-based triamcinolone acetonide formulation (Tri-Nasal) over 7 days were used to describe the pharmacokinetics of this formulation. Available literature data for a suspension-based aqueous triamcinolone acetonide formulation (Nasacort AQ) were used to describe its pharmacokinetic profile after similar single doses of 110, 220, and 440 microg. A PK/PD simulation approach was used to predict the anticipated cumulative cortisol suppression (CCS) of these two formulations. These simulations suggested a cortisol suppression of 8% to 16% for the single and steady-state doses of the solution-based product. Similar CCS estimates were predicted for equivalent doses of the aqueous suspension-based triamcinolone acetonide formulation with no difference between both formulations. Post hoc power analysis suggested that the predicted cortisol suppression is not likely to be significant for either preparation, including the clinically recommended doses of 200 and 220 microg of the solution-based and suspension-based formulations, respectively. In summary, based on the results of this PK/PD simulation, the plasma levels observed afternasal administration of the solution or the aqueous suspension are unlikely to induce a clinically relevant cortisol suppression, especially for the recommended dosing regimens of 200 and 220 microg/day.

    Background and Objective The allergenicity of several German cockroach (Bla-g) antigens at the level of IgE responses is well established. However less is known about the specificity of CD4+ TH responses, and whether differences exist in associated magnitude or cytokine profiles as a function of disease severity. Methods Proteomic and transcriptomic techniques have been employed to identify novel antigens recognized by allergen-specific T cells. To characterize different TH functionalities of allergen-specific T cells, ELISPOT assays with sets of overlapping peptides covering the sequences of known allergens and novel antigens were employed to measure release of IL-5, IFNγ, IL-10, IL-17, and IL-21. Results Using these techniques, we characterized TH responses in a cohort of adult Bla-g sensitized subjects, either with (n=55) or without (n=17) asthma, and non-sensitized controls (n=20). T cell responses were detected for ten known Bla-g allergens and an additional ten novel Bla-g antigens; representing in total a 5-fold increase in the number of antigens demonstrated to be targeted by allergen-specific T cells. Responses of sensitized individuals regardless of asthma status were predominantly TH2, but higher in patients with diagnosed asthma. In asthmatic subjects Bla-g 5, 9 and 11 were immunodominant while, in contrast, non-asthmatic sensitized subjects responded mostly to Bla-g 5, 4, and the novel antigen NBGA5. Conclusions Asthmatic and non-asthmatic cockroach sensitized individuals exhibit similar TH2 polarized responses. Compared to non-asthmatics, however, asthmatic individuals have responses of higher magnitude and different allergen specificity. PMID:26414909

    Rhinitis is a common problem with important comorbidities. In order to search the association between rhinitis, allergic phenotypes and other risk factors in Turkish children, a parental questionnaire about allergic diseases and risk factors, and skin prick test (SPT) with 13 inhalant allergens were performed in a population-based sample of 2774 children aged 9-11 yr. Bronchoprovocation testing with hypertonic saline (HS)and total IgE analysis were limited to a subsample of 350 children. Rhinitis was defined as a problem with sneezing, rhinorrhea, or nasal congestion when the child did not have a viral respiratory infection. The prevalences of ever rhinitis, current (last 12 months) rhinitis (CR), and ever hay fever were 36.3%, 30.6%, and 8.3%, respectively. SPT positivity rate was 20.4% among children with CR. Current wheezing and flexural dermatitis were significantly associated with CR. CR significantly increased the risk of asthma among both atopic and non-atopic subjects [odds ratio (OR), 3.98; 95% CI, 1.81-8.76; and OR, 2.79; 95% CI, 1.82-4.26, respectively]. The association between CR and bronchial hyperreactivity (BHR) was not significant. The multiple logistic regression analysis revealed family atopy (OR=2.25, 95% CI=1.79-2.83, p<0.001), current indoor heating with gas stove (OR=1.78, 95% CI=1.18-2.64, p=0.006) and dampness/molds at home during the first year of life (OR=1.70, 95% CI=1.25-2.31, p=0.001) as significant risk factors for CR. Turkish school children showed a high prevalence of rhinitis with a preponderance of non-atopics. The highly significant association between rhinitis and asthma independent of atopic sensitization emphasize the importance of non-atopic forms of rhinitis.

    Rhinitis has been demonstrated to impose a significant disease burden upon the general population. We sought to determine the prevalence of rhinitis in athletes; to investigate its relationship with co-existing allergic symptoms; and to quantify the impact of rhinitis on quality of life in the athlete.3 subgroups were studied: elite field hockey players (FHP); non-elite FHP; and a sedentary control group.Participants were asked to complete a rhinitis self-report questionnaire; the "Allergic Questionnaire for Athletes" (AQUA), and quality of life Sinonasal Outcome Test - 22 (SNOT-22).142 participants completed the study (52 elite FHP; 40 non-elite FHP; 50 controls). There was a significantly higher prevalence of rhinitis in the elite and non-elite FHP groups than the sedentary control group (52% and 43% vs. 22%, p<0.05). Mean AQUA score was significantly higher in athletes with rhinitis. Quality of life scores were significantly worse in athletes with rhinitis than those without rhinitis (p<0.05).This study suggests regular exercise is associated with a significant increase in the prevalence of rhinitis. Elite FHP were most likely to report rhinitis, but the least likely to be using regular treatment. Quality of life was negatively affected, confirming the importance of nasal health to athlete welfare.

    Background: A circadian rhythm of symptoms has been reported in allergic rhinitis (AR). Severity of all major symptoms of AR, including runny nose, sneezing, and nasal congestion, is typically at its peak in the morning. The objective of this study was to explore the efficacy of the antihistamine and platelet activating factor (PAF) antagonist rupatadine in the morning and evening and to evaluate whether rupatadine provides effective symptom relief throughout the 24-hour dosing interval. Methods: A total of 308 patients ≥18 years of age with PAR was randomly assigned to once-daily rupatadine 10 mg, rupatadine 20 mg, or cetirizine 10 mg for 4 weeks in a placebo-controlled, double-blind study. The main outcome was the morning/evening reflective total symptom score (5TSS) over the treatment period. Secondary endpoints included morning/evening reflective nasal total symptom score (4NTSS), individual symptoms, Pdmax1 as percentage of days with daily severest symptom score ≤1, and subject/investigator evaluation of therapeutic response. Results: All active groups were significantly more effective than placebo in improving morning and evening evaluations of 5TSS (P < 0.001) and 4NTSS (P < 0.001) at 2 or 4 weeks. At morning evaluation, there was a significant reduction from baseline for 5TSS with rupatadine 10 mg (−36.8%, P < 0.01) and 20 mg (−46.3%, P < 0.01) compared with placebo. Similarly, 4NTSS was reduced significantly more with rupatadine 10 mg (−34%, P < 0.05) and 20 mg (−41%, P < 0.01) compared with placebo. In the cetirizine 10 mg group, the reduction was −32.7% and −32.2% for 5TSS and 4NTSS, respectively, but this reduction was not significant compared with placebo. The percentage reduction was greater at evening than at morning evaluation. 5TSS reduction with rupatadine 10 mg (−40.7%, P < 0.05) and 20 mg (−49.9%, P < 0.01) and cetirizine 10 mg (−40.1%, P < 0.05) was significantly better than with placebo. 4NTSS values for active groups

    In subjects with non-steroidal anti-inflammatory drugs (NSAIDs)- exacerbated respiratory disease (NERD) symptoms are triggered by acetyl salicylic acid (ASA) and other strong COX-1 inhibitors, and in some cases by weak COX-1 or by selective COX-2 inhibitors. The mechanism involved is related to prostaglandin pathway inhibition and leukotriene release. Subjects who react to a single NSAID and tolerate others are considered selective responders, and often present urticaria and/or angioedema and anaphylaxis (SNIUAA). An immunological mechanism is implicated in these reactions. However, anecdotal evidence suggests that selective responders who present respiratory airway symptoms may also exist. Our objective was to determine if subjects might develop selective responses to NSAIDs/paracetamol that manifest as upper/lower airways respiratory symptoms. For this purpose, we studied patients reporting asthma and/or rhinitis induced by paracetamol or a single NSAID that tolerated ASA. An allergological evaluation plus controlled challenge with ASA was carried out. If ASA tolerance was found, we proceeded with an oral challenge with the culprit drug. The appearance of symptoms was monitored by a clinical questionnaire and by measuring FEV1 and/or nasal airways volume changes pre and post challenge. From a total of 21 initial cases, we confirmed the appearance of nasal and/or bronchial manifestations in ten, characterized by a significant decrease in FEV1% and/or a decrease in nasal volume cavity after drug administration. All cases tolerated ASA. This shows that ASA tolerant subjects with asthma and/or rhinitis induced by paracetamol or a single NSAID without skin/systemic manifestations exist. Whether these patients represent a new clinical phenotype to be included within the current classification of hypersensitivity reactions to NSAIDs requires further investigation.

    In subjects with non-steroidal anti-inflammatory drugs (NSAIDs)- exacerbated respiratory disease (NERD) symptoms are triggered by acetyl salicylic acid (ASA) and other strong COX-1 inhibitors, and in some cases by weak COX-1 or by selective COX-2 inhibitors. The mechanism involved is related to prostaglandin pathway inhibition and leukotriene release. Subjects who react to a single NSAID and tolerate others are considered selective responders, and often present urticaria and/or angioedema and anaphylaxis (SNIUAA). An immunological mechanism is implicated in these reactions. However, anecdotal evidence suggests that selective responders who present respiratory airway symptoms may also exist. Our objective was to determine if subjects might develop selective responses to NSAIDs/paracetamol that manifest as upper/lower airways respiratory symptoms. For this purpose, we studied patients reporting asthma and/or rhinitis induced by paracetamol or a single NSAID that tolerated ASA. An allergological evaluation plus controlled challenge with ASA was carried out. If ASA tolerance was found, we proceeded with an oral challenge with the culprit drug. The appearance of symptoms was monitored by a clinical questionnaire and by measuring FEV1 and/or nasal airways volume changes pre and post challenge. From a total of 21 initial cases, we confirmed the appearance of nasal and/or bronchial manifestations in ten, characterized by a significant decrease in FEV1% and/or a decrease in nasal volume cavity after drug administration. All cases tolerated ASA. This shows that ASA tolerant subjects with asthma and/or rhinitis induced by paracetamol or a single NSAID without skin/systemic manifestations exist. Whether these patients represent a new clinical phenotype to be included within the current classification of hypersensitivity reactions to NSAIDs requires further investigation. PMID:27489545

    There is concern about the human health effects of inhalation of acid compounds found in urban air pollution. It was the purpose of this study to investigate three of these acid compounds, sulfur dioxide (SO2), sulfuric acid (H2SO4), and nitric acid (HNO3) in a group of allergic adolescent subjects. Subjects were exposed during rest and moderate exercise to 0.7 mumole/m3 (68 micrograms/m3) H2SO4, 4.0 mumole/m3 (0.1 ppm) SO2, or 2.0 mumole/m3 (0.05 ppm) HNO3. Pulmonary functions (FEV1, total respiratory resistance, and maximal flow) were measured before and after exposure. Preliminary analysis based on nine subjects indicates that exposure to 0.7 mumole/m3 H2SO4 alone and in combination with SO2 caused significant changes in pulmonary function, whereas exposure to air or SO2 alone did not. FEV1 decreased an average of 6% after exposure to H2SO4 alone and 4% when the aerosol was combined with SO2. The FEV1 decrease was 2% after both air and SO2 exposures. Total respiratory resistance (RT) increased 15% after the combined H2SO4 exposures, 12% after H2SO4 alone, and 7% after exposure to air. After exposures to HNO3 alone, FEV1 decreased by 4%, and RT increased by 23%. These results are preliminary; final conclusions must wait for completion of the study. PMID:2539990

    Rhinitis is a common problem in childhood and adolescence and impacts negatively on physical, social and psychological well-being. This position paper, prepared by the European Academy of Allergy and Clinical Immunology Taskforce on Rhinitis in Children, aims to provide evidence-based recommendations for the diagnosis and therapy of paediatric rhinitis. Rhinitis is characterized by at least two nasal symptoms: rhinorrhoea, blockage, sneezing or itching. It is classified as allergic rhinitis, infectious rhinitis and nonallergic, noninfectious rhinitis. Similar symptoms may occur with other conditions such as adenoidal hypertrophy, septal deviation and nasal polyps. Examination by anterior rhinoscopy and allergy tests may help to substantiate a diagnosis of allergic rhinitis. Avoidance of relevant allergens may be helpful for allergic rhinitis (AR). Oral and intranasal antihistamines and nasal corticosteroids are both appropriate for first-line AR treatment although the latter are more effective. Once-daily forms of corticosteroids are preferred given their improved safety profile. Potentially useful add-on therapies for AR include oral leukotriene receptor antagonists, short bursts of a nasal decongestant, saline douches and nasal anticholinergics. Allergen-specific immunotherapy is helpful in IgE-mediated AR and may prevent the progression of allergic disease. There are still a number of areas that need to be clarified in the management of rhinitis in children and adolescents.

    Many soybean protein products are processed by enzymatic hydrolysis to attain desirable functional food properties or in some cases to reduce allergenicity. However, few studies have investigated the effects of enzymatic hydrolysis on the allergenicity of soybean products. In this study the allergenicity of soybean protein isolates (SPI) hydrolyzed by Alcalase, trypsin, chymotrypsin, bromelain, or papain was evaluated by IgE immunoblots using eight soybean-allergic patient sera. The biological relevance of IgE binding was evaluated by a functional assay using a humanized rat basophilic leukemia (hRBL) cell line and serum from one subject. Results indicated that hydrolysis of SPI by the enzymes did not reduce the allergenicity, and hydrolysis by chymotrypsin or bromelain has the potential to increase the allergenicity of SPI. Two-dimensional (2D) immunoblot and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis of the chymotrypsin-hydrolyzed samples indicated fragments of β-conglycinin protein are responsible for the apparent higher allergenic potential of digested SPI.

    FXF is a third-generation antihistamine drug and osthole is assumed a natural antihistamine alternative. This paper compares peripheral blood mononuclear cell (PBMC) incubation with FXF and osthole, by studying FXF, osthole and histamine cytokine secretion in PBMC in vitro cultures. Mabtech kits determined the interleukins IL-1β, IL-4, IL-10, IL-13 and TNF-α. The influence of the above active substances on cytokine secretion in PBMC's and serum was assessed: cytokines were IL-1β, IL-4, IL-10, IL-13 and TNF-α; and cytokine levels secreted by untreated PBMCs in pure culture medium formed the absolute control (ctrl). We determined that osthole affects PBMC cytokine secretion to almost precisely the same extent as FXF (IL-1β, IL-4, IL-10 and TNF). In addition osthole had greater IL-13 blocking ability than FXF. Moreover, we observed significantly decreased IL-4 level in histamine/osthole theatment compared to histamine alone. Meanwhile, FXF not significantly decrease the level of IL-4 increased by histamine. This data indicates osthole's strong role in allergic inflamation. All results confirm our hypothesis that osthole is a natural histamine antagonist and therefore can be beneficially used in antihistamine treatment of conditions such as allergies.

    Although antihistamines are highly effective in alleviating many symptoms associated with seasonal allergic rhinitis (SAR), relief from nasal congestion is variable. The efficacy of desloratadine, an effective antihistamine, in combination with pseudoephedrine, a potent nasal decongestant, was evaluated to determine whether combination therapy was more effective than individual component therapy in reducing nasal congestion, as well as other SAR symptoms. This multicenter, randomized, double-blind, three-arm study included 650 patients with SAR. For 2 weeks, patients were administered a combination tablet of desloratadine plus pseudoephedrine (desloratadine/pseudoephedrine, 2.5/120 mg) twice per day (b.i.d.), desloratadine (5 mg) once per day, or pseudoephedrine (120 mg) b.i.d. Patients assessed the severity of their SAR symptoms twice daily on symptom diary cards. The primary variable-change from baseline in the reflective A.M./P.M. total symptom score, excluding nasal congestion-was significantly superior (-6.7) compared with desloratadine (-5.4) or pseudoephedrine (-5.3) alone (p < or = 0.001 versus either group). Secondary efficacy variables including total symptom scores (plus congestion), total nasal symptom scores, and total nonnasal symptom scores were significantly reduced after desloratadine/pseudoephedrine therapy compared with the individual components. The most frequently reported adverse events were insomnia, headache, and dry mouth. Desloratadine/pseudoephedrine, 2.5/120 mg b.i.d., therapy was more effective in reducing total symptom scores of SAR, including nasal congestion, than were the individual components. These results support the use of this combination therapy over desloratadine or pseudoephedrine alone.

    Allergies may be the source of a variety of clinical symptoms. With regard to indoor air, however, the subject will be limited to inhalative allergies. These are diseases which are caused and supported by allergens entering the human organism via the respiratory pathway. The fundamentals of the origin of inhalative allergies are briefly discussed as well as the antigen-antibody reaction and the differentiation between different allergic reactions (Types I and II). In addition, the importance of repetitive infects of the upper respiratory tract for the occurrence of allergies of the respiratory system is pointed out. The most common allergies develop at the mucosae of the nose (allergic rhinitis) and of the bronchiale (allergic asthma bronchiale). Their symptomatology is discussed. Out of the allergologically interesting components of indoor air the following are to be considered primarily: house dust, components of house dust (house dust mite, trogoderma angustum, tenebrio molitor), epithelia of animals, animal feeds, mildew and occupational substances. Unspecific irritants (chimico-physical irritations) which are not acting as allergens, have to be clearly separated from these most frequent allergens. As a possibility of treatment for the therapeutist and the patient, there is the allergen prophylaxis, i.e. an extensive sanitation of the patient's environment including elimination of the allergens and, in addition, an amelioration of the quality of the air with regard to unspecific irritants. To conclude, some socio-medical aspects of respiratory diseases are discussed.

    Background. Although the safety and efficacy of sublingual immunotherapy (SLIT) with a five-grass pollen tablet have been demonstrated in randomized clinical trials (RCTs), these outcomes must always be evaluated in real-life medical practice. Methods. In a prospective, open-label, noninterventional, “real-life” study in Germany, we evaluated the safety, tolerability, and effectiveness of SLIT with a five-grass pollen tablet in adults with grass-pollen-induced allergic rhinoconjunctivitis. Results. 808 adults were enrolled between September 2008 and December 2009. 35.3% of the participants experienced at least one adverse drug reaction (ADR), the most common of which were mild-to-moderate gastrointestinal and respiratory disorders. Serious ADRs considered causally related to SLIT treatment occurred in four patients. Overall, the five-grass pollen tablet was considered to have good or very good tolerability by most investigators and patients. Treatment was associated with the relief of nasal, ocular, and bronchial symptoms and decreased symptomatic medication use. However, interpretation of clinical improvements was limited by lower atmospheric grass pollen levels during the study season (relative to the preceding season). Conclusions. In a large population of patients treated in real-life medical practice, SLIT with a five-grass pollen tablet was safe and well tolerated. The patient-reported symptom relief suggests that SLIT was associated with clinical benefits. PMID:26351635

    Abstract Th2 and Th17 cells are both associated with developing ankylosing spondylitis (AS) and asthma. Th2 cells are also associated with allergic rhinitis and atopic dermatitis (AD). The prevalence of such allergic diseases in AS patients is unknown. In this study, we intended to study the risk of allergic diseases in a 10-year follow-up population of newly diagnosed patients with AS. We used a nationwide 10-year population-based database retrieved from the Longitudinal Health Insurance Database 2005 (LHID2005) in Taiwan. The study cohort comprised 857 patients with AS who had at least 1 claim of inpatient admission or at least 2 claims of ambulatory visit. The comparison cohort consisted of 4285 randomly selected subjects matched with AS group at a ratio of 5:1. We used Cox proportional-hazards regression to determine the 10-year disease-free survival rates after adjusting for potentially confounding factors. The AS patients had a 1.31 times greater risk of developing asthma within 10 years of diagnosis when compared with non-AS age- and sex-matched subjects, after adjusting for other risk factors (95% confidence interval = 1.00–1.75). But the difference was not significantly different. The AS patients also had a 1.46 times and a 1.22 times greater risk of developing allergic rhinitis and AD significantly. AS patients also had a lower allergic disease-free survival rate compared to non-AS group. Our results showed that patients with AS had a higher risk of developing allergic diseases later in life.

    The prevalence of children allergic rhinitis has been increasing in China and associated factors still are not clear. In the present paper, we selected 13,335 parent-reported questionnaires of 4-6 years-old children, in a cross-sectional study from April 2011 to April 2012 in Shanghai city, and investigated associations of various factors with parent-reported allergic rhinitis (doctor-diagnosed) and rhinitis symptoms in childhood. After adjusted by age, sex, family history of atopy, and respondent of questionnaire, we find that no siblings, mother in older age during pregnancy, shorter breastfeeding, using antibiotics in the first year, and home dampness-related exposures, had significant associations with increased prevalence of the studied diseases. Location, type, building area, decoration materials and construction period of the residence, also had significant associations with these diseases. Current parental smoking and pet-keeping had no significant associations with the studied diseases. Incense-burning and using mosquito coils had significant associations with reduced risk of allergic rhinitis and with increased risk of rhinitis symptoms. Using air cleaner and cleaning the residence in high frequency had associations with increased risk, but eating fast food and ice cream often had associations with the reduced risk, of the studied diseases. Families with children being diagnosed allergic rhinitis likely change their lifestyle behaviors. In conclusion, childhood rhinitis could be influenced by heredity and many "environmental exposures". Avoidance behaviors and reverse causation in parental smoking, pet-keeping, and dietary habits for childhood rhinitis should be carefully considered.

    Chronic rhinitis involves inflammation of the upper airways. An association with comorbid conditions, such as rhinosinusitis, asthma, and chronic obstructive pulmonary disease, has been commonly observed in epidemiologic studies. The underlying pathogenesis of these disorders may be similar. Complications of rhinitis include sleep disturbances, learning impairment, and decreased quality of life. It is vital to recognize the complications of rhinitis so that treatment strategies can address rhinitis as well as its comorbidities and complications in a coordinated manner.

    Every pediatrician has likely experienced frustration with cases of chronic nasal symptoms that either do not seem to get better or do show improvement but then worsen again. Often, this leads to the diagnosis of allergic rhinitis or sinusitis and subsequent prescription of medication(s) that may or may not be warranted. This article discusses the various causes of rhinitis, both allergic and nonallergic. Recommendations for treatment place special focus on nasal irrigation and the role that a child's diet can have on chronic nasal symptoms, with the hope of reducing excessive and sometimes unnecessary medication use.

    Abstract Increased viral replication and cytokine production may be associated with the pathogenesis of asthma attacks in rhinovirus (RV) infections. However, the association between increased RV replication and enhanced expression of intercellular adhesion molecule‐1 (ICAM‐1), a receptor for a major RV group, in airway epithelial cells has remained unclear. Furthermore, the inhibitory effects of mucolytics, which have clinical benefits in asthmatic subjects, are uncertain. Human nasal epithelial (HNE) cells were infected with type 14 rhinovirus (RV14), a major RV group. RV14 titers and cytokine concentrations, including interleukin (IL)‐6 and IL‐8, in supernatants, RV14 RNA replication and susceptibility to RV14 infection were higher in HNE cells obtained from subjects in the allergic group (allergic subjects) than in those from subjects in the non‐allergic group (non‐allergic subjects). ICAM‐1 expression and the number and fluorescence intensity of acidic endosomes from which RV14 RNA enters the cytoplasm were higher in HNE cells from allergic subjects, though substantial amounts of interferon (IFN)‐γ and IFN‐λ were not detected in the supernatant. The abundance of p50 and p65 subunits of transcription factor nuclear factor kappa B (NF‐κB) in nuclear extracts of the cells from allergic subjects was higher compared to non‐allergic subjects, and an inhibitor of NF‐κB, caffeic acid phenethyl ester, reduced the fluorescence intensity of acidic endosomes as well as RV titers and RNA. Furthermore, a mucolytic agent, L‐carbocisteine, reduced RV14 titers and RNA levels, cytokine release, ICAM‐1 expression, the fluorescence intensity of acidic endosomes, and NF‐κB activation. The increased RV14 replication observed in HNE cells from allergic subjects might be partly associated with enhanced ICAM‐1 expression and decreased endosomal pH through NF‐κB activation.

    The concept of "united airways disease", based on many similar features and mutual interactions in the pathogenesis of asthma (A) and rhinitis (R), has led to an integral approach to their management. We conducted this study to determine the quantity of the problem of joint incidence of A and R in R. Macedonia, and, perhaps to obtain information on a potential causative effect of the two diseases. Three hundred eighty six patients, who presented with wheezing and/or upper respiratory symptoms at the Pulmology and Allergy Clinic, Skopje, were included during a period of 48 months. The presence of bronchial hyperreactivity - BHR (positive histamine challenge), atopy (prick test to seasonal or perennial inhaled allergens), rhinitis symptoms (such as nasal secretion and obstruction) and X-ray of paranasal sinuses was registered by a specially designed questionnaire. R was diagnosed in 106 of the subjects (27.5%), and A in 280 (72.5%). Among the patients with A, co-incidence with R was found in 219 (76.5%). Including X-ray of paranasal sinuses to the diagnostic protocol increased this percentage to over 90% (256 patients). From the 219 patients with A and R together, 127 (57.99%) had positive atopy. On the other hand, 19 (18.0%) of the rhinitis-only patients had positive BHR without asthma symptoms. The follow up of the rhinitis patients with positive BHR revealed 4 patiets who developed asthma within 36 months, but this was also the case with 2 of the subjects with R and negative BHR. In conclusion, the co-incidence of A and R in our material is 78.21%, or 91.4% (including sinusitis); a greater co-existence of A and R is found in atopic patients. The patients with allergic R are at high risk for developing A and should be monitored in the future and the R symptoms should be adequately treated in order to minimize the risk for developing asthma.

    The CO2 and KTP/532 lasers have been used in the treatment of an allergic and hypertrophic rhinitis for the past several years. As we know, the laser enables a surgeon to perform the operation with minimum hemorrhage and minimized pain, during and after the procedure. Additionally many of these operations can be performed under local anesthesia instead of general anesthesia, on an outpatient basis. The laser is used to irradiate the mucous membranes of the inferior turbinates. Vaporization and cutting is easily done. Post operative management of the local operated area is easy. The advantages of laser surgery over regular surgical techniques are supreme for intranasal operations when performed under local anesthesia.

    Rhinitis is a chronic inflammatory disease of the upper respiratory tract, characterized by a high prevalence and a complex pathogenesis. Work-related rhinitis (WRR) can be divided into occupational rhinitis (OR) and work-exacerbated rhinitis (WER). It is not only considered as a disease entity but also in the context of medical certification as the allergic disease associated with occupational exposure. Epidemiology of work-related rhinitis has been found to vary depending on the occupation and specific exposure, on the other hand the prevalence data may be underestimated due to the lack of uniform diagnostic criteria. This paper reviews the issues comprising the pathogenesis, epidemiology, diagnosis and treatment of patients with work-related rhinitis. It also discusses the significance of the disease in occupational medicine, particularly in terms of preventive worker care, general principles of good practice in primary and secondary WRR prevention and the necessary directions of changes in medical certification in the cases of occupational rhinitis.

    This study was part of an international effort to evaluate the epidemiology of asthma and allergic diseases around the world. The aim was to assess the prevalence and severity of these disorders in Singapore schoolchildren. The international study of asthma and allergies in childhood (ISAAC) written questionnaire was administered to 6238 schoolchildren. The respondents were parents of a 6-7 year cohort (n = 2030), and schoolchildren aged 12-15 years (n = 4208). The overall cumulative and 12 month prevalence of wheezing were 22% and 12%, respectively. The prevalence of doctor diagnosed asthma was 20%. Rhinitis was reported by 44% and chronic rashes by 12%. Multiple logistic regression analysis showed that a higher prevalence of wheezing and rhinitis was associated with males, and subjects of higher socioeconomic status (based on type of housing and total family income). More severe asthma related symptoms were present in Malays and Indians than in the Chinese. Allergic disorders are common in Singapore and prevalence is comparable to some populations in the West. Demographic and socioeconomic factors appear to influence the prevalence and severity of these disorders. PMID:8660075

    Allergic diseases [asthma, rhinitis and atopic dermatitis (AD)] are complex. They are associated with allergen-specific IgE and nonallergic mechanisms that may coexist in the same patient. In addition, these diseases tend to cluster and patients present concomitant or consecutive diseases (multimorbidity). IgE sensitization should be considered as a quantitative trait. Important clinical and immunological differences exist between mono- and polysensitized subjects. Multimorbidities of allergic diseases share common causal mechanisms that are only partly IgE-mediated. Persistence of allergic diseases over time is associated with multimorbidity and/or IgE polysensitization. The importance of the family history of allergy may decrease with age. This review puts forward the hypothesis that allergic multimorbidities and IgE polysensitization are associated and related to the persistence or re-occurrence of foetal type 2 signalling. Asthma, rhinitis and AD are manifestations of a common systemic immune imbalance (mesodermal origin) with specific patterns of remodelling (ectodermal or endodermal origin). This study proposes a new classification of IgE-mediated allergic diseases that allows the definition of novel phenotypes to (i) better understand genetic and epigenetic mechanisms, (ii) better stratify allergic preschool children for prognosis and (iii) propose novel strategies of treatment and prevention.

    Nasal filters (Sanispira) might represent a novel approach in preventing exacerbations of symptoms of seasonal allergic rhinitis by reducing pollen access to nasal cavities. Female and male voluntary patients between the ages of 18 and 64 years living in Naples area and affected by allergic rhinitis were recruited in an open clinical study. All were allergic to Parietaria pollen as assessed by skin-prick and/or RAST test with or without associated sensitization to other pollens such as Gramineae and Olea europaea. A pollen count was also carried out from 10th April until 30th of June 2011. The results of our study show positive statistical differences between the scores of common nasal symptoms and the reduced use of antihistaminic drugs in patients using nasal filters in comparison to non users. Nasal filters constitute a useful mean to reduce symptoms of seasonal allergic rhinitis in patients suffering from pollen allergy.

  4. Does the type of rhinitis influence development of otitis media with effusion in children?

    Otitis media with effusion (OME) is characterized by the presence of fluid in the middle ear cavity behind an intact eardrum and is considered a multifactorial condition with Eustachian tube dysfunction as the underlying pathophysiologic condition. One of the most debated causes of OME is allergy, in particular allergic rhinitis. The aim of this paper is to review the role of rhinitis in the development of OME and in particular the role of both allergic (AR) and non-allergic rhinitis (NAR). Most of the recent literature confirms the role of AR in the development of OME, while there are few reports on the role of NAR. In non-allergic children affected by obstructive adenoid hypertrophy, the presence of mast cells in the nasal smear was associated with a high risk of developing a chronic OME.

    Introduction The incidence of allergies depends on a number of factors, including adopting an urban “western” lifestyle, genetic predispositions, and different regions of residence. Aim To compare the prevalence of allergic conditions (seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR), bronchial asthma (BA), atopic dermatitis (AD)) in a group of countryside versus urban residents in Poland. Material and methods The prevalence of allergic conditions in urban versus countryside settings was assessed using the translated and approved questionnaire developed for international ECRHS II and ISAAC studies. Respondents were selected via random multistage sampling, with proportionate stratified sampling, and the Polish Resident Identification Number (PESEL) as the basis. A total of 18,617 respondents took part in the study. Subsequently, approximately 25% of the subjects underwent outpatient assessments: skin-prick, lung function, peak nasal inspiratory flow (PNIF) tests, as well as history-taking. Results Allergic rhinitis (AR) proved to be the most common condition in the entire study population. Children residing in the countryside were twice more likely to be diagnosed with BA (8.33% vs. 4%; p < 0.05). Conversely, in the adult subgroup, BA was more commonly observed in urban areas. Whereas reported symptom rates were much higher in AR and AD patients, symptomatic BA was proportionately lower with respect to the official diagnoses (underdiagnosed BA phenomenon). Atopic dermatitis was considerably more common in the metropolitan population. One factor that significantly correlated with allergic diseases was a positive family history. Conclusions Inhabitants of metropolitan areas are to a greater extent predisposed to allergic conditions. One factor significantly contributing to allergies is genetic predisposition. Given the scale of the problem, there is an urgent need to implement measures for early prevention and diagnosis of allergies to

    Exposure to tobacco smoke has been associated with harmful effects on child health. The association between tobacco smoke exposure and childhood rhinitis has not been established in developed or developing countries. We investigated the association between serum cotinine levels and rhinitis in a population sample of 1,315 Asian children. Serum cotinine levels were positively associated with rhinitis ever (adjusted odds ratio [AOR] = 2.95; 95% confidence interval [CI]: 1.15–7.60) and current rhinitis (AOR = 2.71; 95% CI: 1.07–6.89), while the association for physician-diagnosed rhinitis approaching borderline significance (AOR = 2.26; 95% CI: 0.88–5.83). Stratified analyses demonstrated significant association of serum cotinine levels with current rhinitis among children without allergic sensitization (AOR = 6.76; 95% CI: 1.21–37.74), but not among those with allergic sensitization. Serum cotinine levels were positively associated with rhinitis ever (AOR = 3.34; 95% CI: 1.05–10.61) and current rhinitis (AOR = 4.23; 95% CI: 1.28–13.97) among adolescents but not in children aged less than 10 years. This population-based study demonstrates supportive evidence for positive association of tobacco smoke exposure with rhinitis, while the effect is mainly confined to non-allergic rhinitis and more pronounced in adolescents than in young children, highlighting the need for raising public health awareness about the detrimental effects of tobacco smoke exposure on children’s respiratory health.

    Asthmatic diseases have been reported since the ancient world. Hay fever for instance, was described for the first time in the late 18th century, and the term “allergy” was introduced about 100 years ago. Today the incidence of allergies is rising; almost one third of the Western population suffers from its side effects. Allergies are some of the most chronic medical complaints, which results in high health expenditures. Therefore, they have a large health and political relevance. Caused by genetic and environmental factors, the group of IgE mediated allergies is large. It consists of e.g. atopic dermatitis, allergic asthma or allergic rhinitis. This paper aims to emphasize the ways of early diagnosis of allergic rhinitis (AR) as AR represents the most important representative of allergic diseases in ENT. PMID:22073091

    Allergic diseases such as asthma, rhinitis, and eczema are increasing in prevalence and affect up to 15% of populations in Westernized countries. The description of Tregs as T cells that prevent development of autoimmune disease led to considerable interest in whether these Tregs were also normally involved in prevention of sensitization to allergens and whether it might be possible to manipulate Tregs for the therapy of allergic disease. Current data suggest that Th2 responses to allergens are normally suppressed by both CD4+CD25+ Tregs and IL-10 Tregs. Furthermore, suppression by these subsets is decreased in allergic individuals. In animal models, Tregs could be induced by high- or low-dose inhaled antigen, and prior induction of such Tregs prevented subsequent development of allergen sensitization and airway inflammation in inhaled challenge models. For many years, allergen-injection immunotherapy has been used for the therapy of allergic disease, and this treatment may induce IL-10 Tregs, leading to both suppression of Th2 responses and a switch from IgE to IgG4 antibody production. Improvements in allergen immunotherapy, such as peptide therapy, and greater understanding of the biology of Tregs hold great promise for the treatment and prevention of allergic disease.

    Objectives The nuclear protein high mobility group protein box 1 (HMGB1) is a proinflammatory mediator that belongs to the alarmin family of proinflammatory mediators, and it has recently emerged as a key player in different acute and chronic immune disorders. Several lines of evidence demonstrate that HMGB1 is actively released extracellularly from immune cells or passively released from necrotic cells. Because of the ability of HMGB1 to sustain chronic inflammation, we investigated whether the protein is present in nasal fluids of patients with different forms of rhinitis. Methods HMGB1 levels were evaluated in nasal fluids of healthy subjects or rhinitis patients who were treated or not treated with different treatments. Results We report that the level of HMGB1 was significantly increased in nasal fluids of patients with allergic rhinitis, patients with NARES (nonallergic rhinitis with eosinophiliac syndrome), as well as patients with polyps. We also found that a formulation containing the HMGB1-binding compound glycyrrhizin (GLT) reduced the HMGB1 content in nasal fluids of rhinitis patients to an extent similar to that with nasal budesonide treatment. We also found that among the cultured human leukocyte populations, eosinophils released higher amounts of HMGB1. Based on the ability of HMGB1 to sustain eosinophil survival and the ability of GLT to inactivate HMGB1, we report that GLT selectively killed cultured eosinophils and had no effect on neutrophils, macrophages, and lymphocytes. Conclusion Collectively, these data underscore the role of HMGB1 in rhinitis pathogenesis and the therapeutic potential of GLT formulations in treatment of chronic inflammatory disorders of the nasal mucosa.

    Chronic nonallergic rhinitis (NAR) is a syndrome rather than a specific disease. A lack of understanding of the pathogenesis of this condition has led to imprecise terminology with several alternate names for the condition, including vasomotor rhinitis, nonallergic rhinopathy, and idiopathic rhinitis. The therapy for NAR is best based on the underlying pathology, which typically exists in a form whereby an abnormality of the autonomic nervous system is dominant or a form in which inflammation seems to be the cause of symptoms. In general the most effective therapy is the combination of an intranasal antihistamine and an intranasal corticosteroid.

    By 2050, the US aging population will nearly double. It will be increasingly important for health care providers to diagnose and manage rhinitis. Nasal symptoms of rhinorrhea, congestion, sneezing, nasal/ocular pruritus, and postnasal drainage affect up to 32% of older adults, and can impact quality of life. Several underlying factors associated with aging may contribute to the pathogenesis of rhinitis in older adults. Although treatment options for rhinitis exist, special considerations need to be made because comorbidities, limited income, memory loss, and side effects of medications are common in older adults and may impact outcomes.

    Many drugs are now in development for the treatment of atopic diseases, including asthma, allergic rhinitis and atopic dermatitis. These treatments are based on improvements in existing therapies or on a better understanding of the cellular and molecular mechanisms involved in atopic diseases. Although most attention has been focused on asthma, treatments that inhibit the atopic disease process would have application to all atopic diseases, as they often coincide. Most of the many new therapies in development are aimed at inhibiting components of the allergic inflammatory response, but in the future there are real possibilities for the development of preventative and even curative treatments.

    Background. Previous studies have shown that psychological stress is linked to asthma prevalence. Parental psychological stress may potentially influence inflammatory responses in their allergic children. The purpose of this study is to clarify the association between maternal psychological status and inflammatory response of allergic young children. Methods. The study subjects were 152 young allergic children (median age: 13 months) who had not shown any allergic symptoms in the past one month. mRNA expression levels of the inflammatory response genes IL-6, IL-8, IL-10 and IL-22 were quantified by qRT-PCR. Maternal psychological status was assessed by standardized questionnaires: the Centre for Epidemiological Studies Depression Scale (CES-D) for depression and the Japanese Perceived Stress Scale (JPSS) for perceived stress. Results. A significant positive association was observed between maternal CES-D scores and IL-6 mRNA expression in the children with asthma. The JPSS scores were also positively associated with IL-8 mRNA expression in asthmatic children and IL-6 mRNA expression in children with allergic rhinitis. Similar trends were observed among children positive for house dust mite-specific IgE, but these associations were not significant. Conclusion. This study supports the hypothesis that maternal psychological stress affects the inflammatory response in their allergic children. PMID:26819847

    This document contains complete guidelines for diagnosis and management of rhinitis developed by the Joint Task Force on Practice Parameters in Allergy, Asthma and Immunology, representing the American Academy of Allergy, Asthma and Immunology, the American College of Allergy, Asthma and Immunology and the Joint Council on Allergy, Asthma and Immunology. The guidelines are comprehensive and begin with statements on clinical characteristics and diagnosis of different forms of rhinitis (allergic, non-allergic, occupational rhinitis, hormonal rhinitis [pregnancy and hypothyroidism], drug-induced rhinitis, rhinitis from food ingestion), and other conditions that may be confused with rhinitis. Recommendations on patient evaluation discuss appropriate use of history, physical examination, and diagnostic testing, as well as unproven or inappropriate techniques that should not be used. Parameters on management include use of environmental control measures, pharmacologic therapy including recently introduced therapies and allergen immunotherapy. Because of the risks to patients and society from sedation and performance impairment caused by first generation antihistamines, second generation antihistamines that reduce or eliminate these side effects should usually be considered before first generation antihistamines for the treatment of allergic rhinitis. The document emphasizes the importance of rhinitis management for comorbid conditions (asthma, sinusitis, otitis media). Guidelines are also presented on special considerations in patients subsets (children, the elderly, pregnancy, athletes and patients with rhinitis medicamentosa); and when consultation with an allergist-immunologist should be considered.

    Diagnosis early in life, sensitization, asthma endotypes, monitoring of disease and treatment progression are key motivations for the exploration of biomarkers for allergic rhinitis and allergic asthma. The number of genes related to allergic rhinitis and allergic asthma increases steadily; however, prognostic genes have not yet entered clinical application. We hypothesize that the combination of multiple genes may generate biomarkers with prognostic potential. The current review attempts to group more than 161 different potential biomarkers involved in respiratory inflammation to pave the way for future classifiers. The potential biomarkers are categorized into either epithelial or infiltrate-derived or mixed origin, epithelial biomarkers. Furthermore, surface markers were grouped into cell-type-specific categories. The current literature provides multiple biomarkers for potential asthma endotypes that are related to T-cell phenotypes such as Th1, Th2, Th9, Th17, Th22 and Tregs and their lead cytokines. Eosinophilic and neutrophilic asthma endotypes are also classified by epithelium-derived CCL-26 and osteopontin, respectively. There are currently about 20 epithelium-derived biomarkers exclusively derived from epithelium, which are likely to innovate biomarker panels as they are easy to sample. This article systematically reviews and categorizes genes and collects current evidence that may promote these biomarkers to become part of allergic rhinitis or allergic asthma classifiers with high prognostic value.

    Vasomotor rhinitis (VMR) is a common but poorly understood disorder of which there are two major subgroups: VMR(w/t), triggered by weather/temperature and VMR(ir), triggered by airborne irritants. No specific biological pathways or specific treatments for VMR(w/t) or VMR(ir) have been identified. However, intranasal corticosteroids (INSs) are effective in treating many forms of nonallergic rhinitis that include these conditions. A recently introduced INS with established efficacy in allergic rhinitis and enhanced affinity, fluticasone furoate, may possess the potency and safety profile required to treat chronic VMR(w/t). Two replicate studies (FFR30006 and FFR30007) were conducted in six countries to evaluate the efficacy and safety of fluticasone furoate nasal spray in subjects with VMR(w/t). After a 7- to 14-day screening period, subjects (n = 699) with symptomatic VMR(w/t) received fluticasone furoate, 110 mug q.d. or placebo for 4 weeks in these two randomized, double-blind, parallel-group studies. Subjects rated their nasal symptoms (congestion, rhinorrhea, and postnasal drip) twice daily on a 4-point categorical scale and evaluated their overall response to treatment at study end. Fluticasone furoate did not significantly improve daily reflective total nasal symptom scores, the primary end point, versus placebo (p = 0.259) and there was no improvement in any other measure of efficacy. The active treatment was well tolerated. Fluticasone furoate was not effective in treating subjects with a newly defined condition, weather-sensitive VMR. These unexpected results suggest that VMR(w/t) is a distinct subgroup of VMR that is refractory to treatment with INSs. Additional study of other treatments for VMR(w/t) (including INSs) is warranted.

    Systemic reactions to Hymenoptera stings can be fatal and represent a reduction in the quality of life. The immune mechanisms involved in venom allergic subjects are barely known. Nevertheless, a shift towards a Th1-type response with an increase in IFNγ levels has been observed after venom immunotherapy (VIT). There is currently no information available about the expression of markers on CD4+ T-cells or their involvement in venom allergy, nor following VIT. For this, we have studied the expression of Th1 and Th2-cell markers, homing receptors and activation markers on CD4+ T-cells of subjects who presented systemic allergic reactions, mainly to Polistes dominulus, and after receiving a 4-month conventional VIT protocol. The markers studied were: CD26 (Th1), CD30 (Th2), CXCR4, CXCR3 (Th1), CCR4 (Th2), CD154 (CD40L), CD152 (CTLA-A), and ICOS. We also determined the IL-4 (Th2) and IFNγ (Th1) intracellular cytokine levels in T-cells and carried out a basophil activation test (BAT). Comparing venom allergic subjects with non-allergic healthy controls, we have found up-regulation of CD26, CXCR4, CXCR3, CD154 and ICOS. Conversely, a down-regulation of CD30, CD154 and CD152 occurred upon immune intervention, whereas the remaining markers were not affected. Equally, VIT has been shown to be effective, as evidenced by the decrease of basophil degranulation and increase of IFNγ levels in T-cells after the fourth month of treatment. These new findings highlight the possible application of these surface molecules as markers to distinguish between symptomatic and asymptomatic subjects sensitized to Hymenoptera venom, as well as revealing information about the immune changes associated with VIT.

    Filaggrin gene (FLG) null mutations are considered associated with atopic dermatitis. This study was conducted to determine the prevalence of FLG null mutations R501X, 2282del4, R2447X and S3247X in the Croatian population and their role in the occurrence of allergic diseases including atopic dermatitis, allergic rhinitis, asthma and allergic contact dermatitis (ACD). Study enrolled 440 freshmen with defined allergic diseases by means of both present symptoms in International Study of Asthma and Allergies in Childhood questionnaire (relevant respiratory and/or skin symptoms) and markers of allergic sensitization (positive skin prick and/or patch test). FLG null mutations were successfully genotyped in 423 students of which 11 (2.6%) were carriers of FLG null mutation: 1/423 (0.2%) was heterozygous for R501X and 10/423 (2.4%) were heterozygous for 2282del4. No carriers of R2447X and S3247X mutations were identified. In wild-type FLG carriers (412 subjects), atopic dermatitis was present in 45 (11%), allergic rhinitis in 70 (17%) and allergic asthma in 29 (7%) students. Twenty-five of 393 (7%) patch-tested wild-type FLG carriers had ACD. Among 11 FLG null mutation carriers, four had one or more allergic diseases, and five had reported skin symptoms without defined allergic sensitization (positive skin prick test and/or patch test). FLG null mutations were not confirmed as a predictor of analysed allergic diseases, but were confirmed as an independent predictor of skin symptoms (OR 17.19, 95% CI 3.41-86.6, P < 0.001). Our results in general indicate a low frequency of FLG null mutations in the studied Croatian population supporting a theory of a latitude-dependent distribution of FGL null mutations in Europe, with a decreasing north-south gradient of R501X and 2282del4 mutation frequency. The relation between FLG null mutations and skin disorders was confirmed.

    This work is concerned with the problem of the nature of the atrophic rhinitis in swine. Our study demonstrates that the filter-passers when injecting intranasal provoke catarrhal rhinitis in sucking-pigs and rabbits and the disease lasts 10-12 days. Guinea-pigs and white mice show no disease symptoms after injection. After four passages of filter-passers through sucking-pigs, the pathogenic properties do not restore. The sucking-pigs and laboratory animals show no changes in organs and in nasal cavity. The findings of cytogenetic and allergic investigations indicate genetic aspects of this disease. To eliminate atrophic rhinitis, it is necessary to reveal heterozygotes, carry out experimental matings and analysis of hybrids. To date, a recessive gene is considered to mediate the disease. To obtain healthy offspring, animals heterozygous for this gene should be bred.

    Purpose Lipopolysaccharide (LPS) is a cell wall component of Gram-negative bacteria and important for pro-inflammatory mediators. This study aimed to establish a rhinitis model using ovalbumin (OVA) and LPS in order to evaluate the role of interleukin (IL)-17 in the pathogenesis of an LPS-induced non-eosionophilic rhinitis model. Methods Mice were divided into 4 groups and each group consisted of 10 mice (negative control group, allergic rhinitis model group, 1-µg LPS treatment group, and 10-µg LPS treatment group). BALB/c mice were sensitized with OVA and 1 or 10 µg of LPS, and challenged intranasally with OVA. Multiple parameters of rhinitis were also evaluated to establish the LPS-induced rhinitis model. IL-17 knockout mice were used to check if the LPS-induced rhinitis model were dependent on IL-17. Eosinophil and neutrophil infiltration, and mRNA and protein expression profiles of cytokine in nasal mucosa or spleen cell culture were evaluated using molecular, biochemical, histopathological, and immunohistological methods. Results In the LPS-induced rhinitis model, neutrophil infiltration increased in the nasal mucosa, and systemic and nasal IL-17 and interferon-gamma (IFN-γ) levels also increased as compared with the OVA-induced allergic rhinitis model. These findings were LPS-dose-dependent. In IL-17 knockout mice, those phenotypes (neutrophil infiltration, IL-17, and IFN-γ) were reversed, showing IL-17 dependency of LPS-induced rhinitis. The expression of vascular endothelial growth factor (VEGF), an important mediator for inflammation and angiogenesis, decreased in IL-17 knockout mice, showing the relationship between IL-17 and VEGF. Conclusions This study established an LPS-induced rhinitis model dependent on IL-17, characterized by neutrophil infiltration and increased expression of IL-17. PMID:28102062

    The global prevalence of allergic rhinitis has been on the increase and recent clinical experience in Malta has shown a similar trend. The aim of this study was to investigate the role of atopy in 415 patients presenting with rhinitis of at least 3 months duration, and to identify the common allergens responsible. Presenting clinical features, past and family history of seasonal allergic symptoms, exposure to cigarette smoking, pet ownership and occupation were analysed. All patients were skin tested for common allergens. Fifty-five per cent of patients were atopic, the main allergens responsible being house dust mite, cat dander and grass pollen. Rhinorrhoea and sneezing were significantly more common in atopic patients, who were more likely to have a past history and family history of seasonal asthma, eczema or rhinoconjunctivitis. Skin test-negative patients with idiopathic rhinitis were mostly females and tended to present a decade later. Differentiation between atopic and idiopathic chronic rhinitis may be helpful in the clinical setting in order to help predict response to treatment.

    2016-11-01

    Healthcare workers (HCWs) are exposed to a range of high and low molecular weight agents that are allergic sensitizers or irritants including cleaners and disinfectants, natural rubber latex, and various medications. Studies have shown that exposed HCWs are at risk for work-related rhinitis and asthma (WRA). Work-related rhinitis may precede development of WRA and should be considered as an early marker of WRA. Avoidance of causative exposures through control strategies such as elimination, substitution, engineering controls, and process modification is the preferred primary prevention strategy for preventing development of work-related allergic diseases. There is limited evidence for the effectiveness of respirators in preventing occupational asthma. If sensitizer-induced WRA is diagnosed, it is important to avoid further exposure to the causative agent, preferably by more rigorous application of exposure control strategies to the workplace. This review focuses on allergic occupational respiratory diseases in HCWs.

    Oral bepotastine is a second-generation histamine H(1) receptor antagonist that also suppresses some allergic inflammatory processes. Numerous short- and long-term clinical trials and surveillance studies have shown that twice-daily bepotastine is an effective and generally well tolerated antihistamine in the treatment of patients with allergic rhinitis, chronic urticaria or pruritus associated with skin conditions (eczema/dermatitis, prurigo or pruritus cutaneus). Bepotastine 20 mg/day was significantly more effective than terfenadine 120 mg/day in patients with perennial allergic rhinitis, as evaluated by the final global improvement rating and several other endpoints in a phase III trial. In phase III trials in patients with chronic urticaria, bepotastine 20 mg/day was more effective than placebo in improving levels of itching and eruption, and as effective as terfenadine 120 mg/day with regard to the final global improvement rating and other endpoints. In a noncomparative trial in patients with pruritus associated with skin diseases, the majority of bepotastine recipients in the overall population, as well as in the specific skin disease subgroups (eczema/dermatitis, prurigo or pruritus cutaneus), had a final global improvement rating of moderate or greater. Bepotastine was generally well tolerated in adult and paediatric patients with allergic conditions.

    Seasonal allergic conjunctivitis (SAC) and perennial allergic conjunctivitis (PAC) as well as intermittent and persistent allergic rhinitis are widespread diseases. Because a combined occurrence of ocular and nasal symptoms is very common the summarising term allergic rhinoconjunctivitis is frequently used. SAC and PAC representing the two acute forms of allergic conjunctivitis account for more than 90 % of all cases of allergic conjunctivitis. Compared to the chronic forms of allergic conjunctivitis their course of disease is milder. Nevertheless because of their high prevalence and the proven influence on patients' quality of life they possess clinical and socioeconomic relevance. Allergic rhinoconjunctivitis is caused by a type 1 IgE-mediated hypersensitivity reaction that is provoked by aeroallergens in the majority of cases. The pathognomonic sign is itching. Besides, typical ocular findings are chemosis, conjunctival injection, watery secretion and lid swelling. Otorhinolaryngologists' findings include rhinorrhea, postnasal drip and sneezing. Problems in breathing through the nose resulting from nasal obstruction can cause impaired nighttime sleep and daytime somnolence. In addition to a reduction of allergen exposure by modification of environment and life style factors, in mild forms of SAC and PAC artificial tears are recommended. Topical antihistamines can generate rapid relief from acute symptoms and itching. Topical mast cell stabilisers however provide long-term effects. Dual action drugs that combine antihistamines and mast cell stabilisers show increased patient compliance due to reduced application frequency. Use of topical steroids should be cautious and only temporary. For prolonged treatment periods unpreserved anti-allergic eye-drops should be preferred. Combined topical antihistamines and new-generation topical nasal steroids often used by otorhinolaryngologists demonstrate a good safety profile without systemic side effects. In summary

    Until recently the prevalence of asthma in Sweden was assessed to be 2-3 per cent. An increase in the prevalence of asthma and allergic rhinitis was noted among new conscripts undergoing health work-ups prior to military service with the most marked increase in northern Sweden, were 5 per cent of conscripts were reported to have asthma. In southern Sweden the prevalence remained about 2 per cent. More recent questionnaire studies in mid- and southern Sweden have reported similar rates of respiratory symptoms and use of anti-asthmatic drugs as in northern Sweden, suggesting that there may be no difference in asthma prevalence between the north and the south of the country. The exact prevalence of allergic diseases among Swedish adults is still not clear, but 40 per cent of adults in northern Sweden report that they often have wheezing in the chest, attacks of breathlessness, longstanding cough or sputum production. In questionnaire studies among children about 40 per cent of respondents have reported that they had asthma, allergic rhinitis or other type of hypersensitivity. The absence of generally accepted diagnostic criteria for asthma and allergic disorders in epidemiological studies makes comparison of prevalence difficult. It is thus not possible to be sure that the prevalence of asthma and allergic disorders in Sweden has recently increased. Risk factors for the development of asthma and allergic disorders are under study in Sweden. Several studies report an association in children between urban living and allergic disorders.

    An increasing proportion of the worldwide population is affected by allergic diseases such as allergic rhinitis (AR), atopic dermatitis (AD) and allergic asthma and improved treatment options are needed particularly for severe, refractory disease. Allergic diseases are complex and development involves both environmental and genetic factors. Although the existence of a genetic component for allergy was first described almost 100 years ago, progress in gene identification has been hindered by lack of high throughput technologies to investigate genetic variation in large numbers of subjects. The development of Genome-Wide Association Studies (GWAS), a hypothesis-free method of interrogating large numbers of common variants spanning the entire genome in disease and non-disease subjects has revolutionised our understanding of the genetics of allergic disease. Susceptibility genes for asthma, AR and AD have now been identified with confidence, suggesting there are common and distinct genetic loci associated with these diseases, providing novel insights into potential disease pathways and mechanisms. Genes involved in both adaptive and innate immune mechanisms have been identified, notably including multiple genes involved in epithelial function/secretion, suggesting that the airway epithelium may be particularly important in asthma. Interestingly, concordance/discordance between the genetic factors driving allergic traits such as IgE levels and disease states such as asthma have further supported the accumulating evidence for heterogeneity in these diseases. While GWAS have been useful and continue to identify novel genes for allergic diseases through increased sample sizes and phenotype refinement, future approaches will integrate analyses of rare variants, epigenetic mechanisms and eQTL approaches, leading to greater insight into the genetic basis of these diseases. Gene identification will improve our understanding of disease mechanisms and generate potential

    Abstract Objective: To describe the frequency and etiology of rhinitis, oral breathing, types of malocclusion and orofacial disorders in patients treated for dental malocclusion. Methods: Patients with poor dental occlusion (n=89, 8-15 years) undergoing orthodontic treatment at the Postgraduate Orthodontics Center (São Paulo, Brazil) participated in the study. Rhinitis and oral breathing were diagnosed by anamnesis, clinical assessment and allergic etiology of rhinitis through immediate hypersensitivity skin prick test with airborne allergens. The association between types of breathing (oral or nasal), rhinitis and types of dental malocclusion, bruxism and cephalometric alterations (increased Y axis of facial growth) compared to standard cephalometric tracing (Escola de Odontologia da Universidade de São Paulo) were assessed. Results: The frequency of rhinitis in patients with dental malocclusion was 76.4% (68), and, of these, 81.7% were allergic (49/60 positive skin prick test), whereas the frequency of oral breathing was 62.9%. There was a significant association between an increased Y axis of facial growth and oral breathing (p<0.001), as well as between oral breathing and rhinitis (p=0.009). There was no association between rhinitis and bruxism. Conclusions: The frequency of rhinitis in children with dental malocclusion is higher than that in the general population, which is approximately 30%. Patients with oral breathing have a tendency to a dolichofacial growth pattern (increased Y axis of facial growth). In patients with rhinitis, regardless of the presence of oral breathing, the dolichofacial growth tendency was not observed. PMID:26631324

    Fungal rhinitis and sinusitis in dogs are quite common reasons of chronic nasal discharge and rhinoscopy in such cases is commonly suggested. Forty three dogs were examined using rhinoscopy because of the presence of chronic airway symptoms. Clinical examination, routine hematology and serum biochemistry profiles, nasal and frontal sinus radiographs were made in all animals. Additionally, computed tomography in one dog was performed. Samples for histopathology were taken from 9 patients during rhinoscopy, additionally, from 8 of these patients samples for cytopathology were collected by blind nasal swab technique. In 9 of 43 dogs (20,5%), all males aged 1 to 13 years, examinations led to a diagnosis of fungal rhinitis. In 2 cases a diagnosis of fungal rhinitis was obtained based solely on cytopathology, while in 7 cases - mycosis of nasal mucosa was confirmed by histopathology. The present study revealed that cytopathological examination of nasal swabs has a low diagnostic value in the case of nasal infections in dogs. Although, in some dogs cytopathology, together with other widely available diagnostic techniques was sufficient to reliably diagnose fungal rhinitis, histopathology of samples collected during rhinoscopy is still the gold standard in such cases.

    BACKGROUND AND OBJECTIVES: The relationship between allergic diseases and internalizing disorders has not been well characterized with regard to multiple allergic diseases or longitudinal study. The objective of this study was to examine the association between multiple allergic diseases in early childhood with validated measures of internalizing disorders in the school-age years. METHODS: Children enrolled in the Cincinnati Childhood Allergy and Air Pollution Study underwent skin testing and examinations at ages 1, 2, 3, 4, and 7 years. At age 7, parents completed the Behavior Assessment System for Children, Second Edition (BASC-2), a validated measure of childhood behavior and emotion. The association between allergic diseases at age 4, including allergic rhinitis, allergic persistent wheezing, atopic dermatitis, and allergic sensitization, and BASC-2 internalizing, anxiety, and depression T scores at age 7 was examined by logistic and linear regression, adjusting for covariates. RESULTS: The cohort included 546 children with complete information on allergic disease and BASC-2 outcomes. Allergic rhinitis at age 4 was significantly associated with elevated internalizing (adjusted odds ratio [aOR]: 3.2; 95% confidence interval [CI]: 1.8–5.8), anxiety (aOR: 2.0; 95% CI: 1.2–3.6), and depressive scores (aOR: 3.2; 95% CI: 1.7–6.5) at age 7. Allergic persistent wheezing was significantly associated with elevated internalizing scores (aOR: 2.7; 95% CI: 1.2–6.3). The presence of >1 allergic disease (aOR: 3.6; 95% CI: 1.7–7.6) and allergic rhinitis with comorbid allergic disease(s) (aOR: 4.3; 95% CI: 2.0–9.2) at age 4 had dose-dependent associations with internalizing scores. CONCLUSIONS: Children with allergic rhinitis and allergic persistent wheezing at age 4 are at increased risk of internalizing behaviors at age 7. Furthermore, multiple allergic diseases had a dose-dependent association with elevated internalizing scores. PMID:26715608

    Allergic disease is caused by exposure to normally innocuous substances that activate mast cells. Mast cell-mediated allergic inflammation is closely related to a number of allergic disorders, such as anaphylaxis, allergic rhinitis, asthma and atopic dermatitis. The discovery of drugs for treating allergic disease is an interesting subject and important to human health. The aim of the present study was to investigate the anti‑allergic and anti-inflammatory effects of the aqueous extract of Pogostemon cablin (Blanco) Benth (AEPC) (a member of the Labiatae family) using mast cells, and also to determine its possible mechanisms of action. An intraperitoneal injection of compound 48/80 or a serial injection of immunoglobulin E and antigen was used to induce anaphylaxis in mice. We found that AEPC inhibited compound 48/80‑induced systemic and immunoglobulin E-mediated cutaneous anaphylaxis in a dose-dependent manner. The release of histamine from mast cells was reduced by AEPC, and this suppressive effect was associated with the regulation of calcium influx. In addition, AEPC attenuated the phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated expression of pro-inflammatory cytokines in mast cells. The inhibitory effects of AEPC on pro-inflammatory cytokines were dependent on the activation of nuclear factor (NF)-κB and p38 mitogen-activated protein kinase (MAPK). AEPC blocked the PMACI-induced translocation of NF-κB into the nucleus by hindering the degradation of IκBα and the phosphorylation of p38 MAPK. Our results thus indicate that AEPC inhibits mast cell‑mediated allergic inflammation by suppressing mast cell degranulation and the expression of pro-inflammatory cytokines caused by reduced intracellular calcium levels and the activation of NF-κB and p38 MAPK.
