Abstract
Allergic and immunologic conditions, including asthma, food allergy, atopic dermatitis, and allergic rhinitis, are among the most common chronic conditions in children and adolescents that often last into adulthood. Although rare, inborn errors of immunity are life-altering and potentially fatal if unrecognized or untreated. Thus, allergic and immunologic conditions are both medical and public health issues that are profoundly affected by socioeconomic factors. Recently, studies have highlighted societal issues to evaluate factors at multiple levels that contribute to health inequities and the potential steps toward closing those gaps. Socioeconomic disparities can influence all aspects of care, including health care access and quality, diagnosis, management, education, and disease prevalence and outcomes. Ongoing research, engagement, and deliberate investment of resources by relevant stakeholders and advocacy approaches are needed to identify and address the impact of socioeconomics on health care disparities and outcomes among patients with allergic and immunologic diseases.

Ragweed pollen concentration predicts seasonal rhino-conjunctivitis and asthma severity in patients allergic to ragweed. Sci Rep 2022; 12:15921. [PMID: 36151263 PMCID: PMC9508093 DOI: 10.1038/s41598-022-20069-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Accepted: 09/08/2022] [Indexed: 11/16/2022] Open
Abstract
In this work, we investigate the correlation between ragweed pollen concentration and conjunctival, nasal, and asthma symptom severity in patients allergic to ragweed pollen using ambient pollen exposure in the Milan area during the 2014 ragweed season We calculate the pollen/symptom thresholds and we assess the effectiveness of ragweed allergen immunotherapy (AIT). A total of 66 participants allergic to ragweed (Amb a 1) were enrolled in the study and divided into two groups: AIT treated (24) and no AIT treated (42). Pollen counts and daily symptom/medication patient diaries were kept. Autoregressive distributed lag models were used to develop predictive models of daily symptoms and evaluate the short-term effects of temporal variations in pollen concentration on the onset of symptoms. We found significant correlations between ragweed pollen load and the intensity of symptoms for all three symptom categories, both in no AIT treated (τ = 0.341, 0.352, and 0.721; and ρ = 0.48, 0.432, and 0.881; p-value < 0.001) and in AIT treated patients (\documentclass[12pt]{minimal}

In both groups, we observed a positive correlation between the number of symptoms reported and drug use. Mean symptom levels were significantly higher in no AIT treated than in AIT treated patients (p-value < 0.001) for all symptom categories. Pollen concentration thresholds for the four symptom severity levels (low, medium–low, medium–high and high) were calculated. Ragweed pollen concentration is predictive of symptom severity in patients with a ragweed (Amb a 1) allergy. Patients treated with AIT had significantly reduced mean symptom levels compared to those without AIT.

Abstract
BACKGROUND Allergic rhinitis (AR) is a very common chronic condition that affects nearly one-quarter of the adult population worldwide. The optimal management of AR includes useful information on the several aspects of the condition. Social media and online platforms are increasingly being used to obtain health related information. OBJECTIVE The study aimed to examine and evaluate the popularity and usefulness of YouTube videos on allergic rhinitis. METHODS Out of 225 screened videos, 86 met the inclusion criteria. A scoring scheme was designed to evaluate and rate the content of the extracted data. Data on views, likes, dislikes, and comments were extracted, and data on source of uploader, duration and content quality were recorded. RESULTS 43% of the videos were classified as useful, 36 % as misleading, and 21 % as neither useful nor misleading. Although professional health care providers uploaded two-thirds of the videos, they accounted for only 24.4% of the total videos. Videos uploaded by TV shows and YouTube channels had by far the most user interaction, accounting for 66.9% of the total likes, 66.8 % of the total dislikes, and 54.0 % of the total comments. This source alone accounted for 23.4% of the total views, but for 48% of the total misleading videos. CONCLUSION The usefulness of YouTube videos on allergic rhinitis is varying and less than half of the videos provided useful information. If the proper conditions are met, selected YouTube videos on allergic rhinitis can be used as a source of information for patient education.

J Family Community Med 2020; 27:186-191. [PMID: 33354149 PMCID: PMC7745787 DOI: 10.4103/jfcm.jfcm_103_20] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 05/08/2020] [Accepted: 07/02/2020] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND: Allergic rhinitis (AR) is characterized by nasal itch, sneezing, watery or mucous rhinorrhea, nasal obstruction, and nasal or pharyngeal irritation. If untreated, AR can impair patients' quality of life (QOL). Azelastine hydrochloride (AH), histamine receptor antagonists, has anti-inflammatory and mast cell stabilizing properties. Fluticasone furoate (FF) is an anti-inflammatory agent with action on mast cells, eosinophils, neutrophils, macrophages, and lymphocytes. This study compares the efficacy and safety of these medications in AR. MATERIALS AND METHODS: Patients in the study had been clinically diagnosed with AR. In each group, there were 75 randomized patients who were to receive either FF (27.5 μg/spray) or AH (0.10%) intranasally twice daily. Assessment in terms of symptoms (total nasal symptom score), signs (endoscopic staging), QOL, eosinophil count, and sensory attributes was done at baseline, day 7, and day 15. Adverse effects were recorded, and the cost incurred was analyzed. Paired and umpaired t-test were used to compare symptom scores, QOL scores, and absolute eosinophil count within and between the groups, respectively. RESULTS: The total number of patients was 150 (76 males and 74 females); the mean age for FF group was 26.23 ± 5.2 years, and 26.96 ± 4.8 years for AH group. By day 7, there was a reduction of all scores in both medications, but the reduction in reduction was highly significant with FF (P = 0.001). There was a significant reduction (P = 0.001) in absolute eosinophil count both in blood and nasal smears by day 15 in both the groups; the reduction was significant (P = 0.001) with fluticasone. Adverse reactions were reported by 33.3% of patients receiving FF and 28% patients receiving AH. CONCLUSION: Fluticasone furoate produced sustained relief of symptoms, signs, and sensory attributes with a greater reduction in eosinophil count in comparison with AH in patients with allergic rhinitis.

Abstract
In this review, we describe how pollen counts are performed, the health effects caused by exposure to varying amounts of pollen, the clinical utility of reporting pollen counts to the public, and how that information can be used by patients who have allergies to improve their health. The public is very interested in pollen counts, particularly if the counts provide a forecast of expected pollen exposure for the next few days. Traditional pollen counts are labor-intensive; poorly distributed; and, since the counts are usually 1-day-old, do not provide forecasts that can be acted on. New methods that provide short- and long-term pollen forecasts can provide this information to allergic individuals so that they can respond to changing outdoor conditions. Studies of the relationship between artificial and natural exposure to pollen and development of symptoms have provided improved understanding into how much pollen it takes to cause symptoms. Thresholds for pollen counts that trigger symptoms vary by pollen type, sensitivity of the population, and interactions with other atmospheric exposures. Strategies to inform the public when the pollen count poses a health risk have been proposed along with computerized systems that provide personalized pollen alerts. The best performing public notification system was a "traffic light system" that reported pollen exposure as low, 0-30; intermediate, 31-50; or high, 51-150. This system outperformed other threshold systems used in Sweden and in Britain/Denmark. Continued improvements in pollen forecasting models combined with data provided by automated pollen counters and better public reporting should permit allergic individuals and urban planners to adapt effectively to changes in outdoor aeroallergen exposures.

Abstract
Objective: One of the possible ways of changing human health might be through the oral mucosa. One of tongue disorders is geographic tongue (GT), which classic manifestation is an area of erythema, with atrophy of filiform papillae of the tongue, surrounded by a serpiginous, white, hyperkeratotic border. Saliva is a rich source of antioxidant and fulfills an important role in maintaining the normal function of the oral cavity. The purpose of the present study was to investigate the status of salivary antioxidant and immunoglobulin E in patients with GT and healthy people. Materials and Methods: In this case-control study, samples were gathered from high school students in three municipal regions of Kermanshah, Iran by using multistage random cluster sampling method. The samples included 30 patients with GT (15 men and 15 women with the mean age of 17.6 ± 0.72) and 30 healthy volunteers (15 men and 15 women with the mean age of 17.1 ± 0.61). Saliva samples were collected through standard method, and total antioxidant capacity (TAC), catalase (CAT), and salivary immunoglobulin E were measured. Results: In patients with GT, unstimulated salivary shows increased level of immunoglobulin compared with that of control group (P = 0.013). However, there was no significant relationship between control and GT patient groups regarding TAC of saliva (P = 0.91) and CAT (P = 0.83). Conclusion: It seems that the activity of CAT enzyme and TAC of saliva does not play primary role in the pathogenesis of GT. However, the level of immunoglobulin E present in saliva can function as an indicator of increased sensitivity in GT.

Abstract
BACKGROUND The co-existence of allergic rhinitis (AR) and obstructive sleep apnea (OSA) is a common phenomenon in clinical practice. AR has long been considered a risk factor for OSA. However, the relationship is not completely clear. Therefore, we conducted a meta-analysis to evaluate the prevalence of AR in sleep-disordered breathing (SDB) /OSA and their relationship. METHODS A comprehensive literature search was performed in PubMed/Medline, Google Scholar, Wiley Online Library, EMBASE, and Web of Science. Data were analyzed and pooled to estimate effect size (ES) /odds ratio (OR) with 95% confidence intervals (95%CI). Heterogeneity was quantified and evaluated by chi-squared-based Q-test and I2 test, with P < .05 and I > 50% indicating evidence of heterogeneity. RESULTS 44 studies contained 6086 participants were included in this meta-analysis. For adults, the prevalence of AR was 22.8 (95% CI, 15.0-30.6) % in SDB and 35.2 (95% CI, 25.6-44.7) % in OSA. In children with SDB and OSA, the prevalence of AR was 40.8 (95% CI, 24.3-57.2) %, and 45.2 (95% CI, 25.4-65.0) % respectively. The odds ratios of prevalence of the SDB pediatric patients with AR was 2.12 (95%CI, 1.75, 2.57; P < .0001) times higher than that of non-SDB pediatric patients. There were no significant differences between OSA adults with or without AR in BMI (Body Mass Index), neck circumference, apnea hypopnea index (AHI) and epworth sleep scale score (ESS). CONCLUSION The prevalence of AR in OSA/SDB is considerably high and children with SDB suffering from a higher incidence of AR than non-SDB. OSA adults accompanied with AR do not have any influences on sleep parameters.

Abstract
AbstractObjectives:To observe the five-year efficacy of standardised specific subcutaneous immunotherapy for house dust mite allergy in monosensitised and polysensitised children with persistent allergic rhinitis.Methods:From January 2007 to August 2009, 236 children with persistent allergic rhinitis were divided into 2 groups: 1 group received standardised specific subcutaneous immunotherapy using house dust mite extract; the other received pharmacotherapy with intranasal corticosteroids and oral antihistamines. A total of 193 patients (106 in the immunotherapy group and 87 in the pharmacotherapy group) completed treatment. Scores for symptoms, total medication and quality of life were evaluated.Results:The subcutaneous immunotherapy group demonstrated a significant reduction in visual analogue scale scores, Rhinoconjunctivitis Quality of Life Questionnaire scores and total medication scores (p < 0.05) compared with the pharmacotherapy group. No significant differences in the visual analogue scale and Rhinoconjunctivitis Quality of Life Questionnaire scores were found between the polysensitised and monosensitised subgroups (p > 0.05). No serious adverse events occurred.Conclusion:Standardised subcutaneous immunotherapy has long-term efficacy for children with persistent allergic rhinitis. Single-allergen subcutaneous immunotherapy was appropriate for allergic rhinitis caused by multiple allergens, including house dust mites, in the paediatric population.

Abstract
Allergic rhinitis and other rhinitis subtypes are increasingly becoming some of the most prevalent and expensive medical conditions that affect the U.S. POPULATION Both direct health care costs and indirect costs significantly impact the health care system due to delays in diagnosis, lack of treatment, ineffective treatment, poor medication adherence, and associated comorbidities. Many patients who have AR turn to over-the-counter medications for relief but often find themselves dissatisfied with the results. Determining the correct diagnosis, followed by initiation of the most-effective treatment(s), is essential to provide patients with better symptomatic management and quality of life. Although there are many options, currently available combination therapies, e.g., azelastine with fluticasone and intranasal corticosteroids with nasal decongestants, offer distinct advantages for the management of complex rhinitis phenotypes. Further research is required to investigate the pathomechanisms and biomarkers for mixed rhinitis and nonallergic vasomotor rhinitis subtypes that will lead to novel targeted therapies for these conditions.

Abstract
OBJECTIVES To quantify the cost difference between conventional symptomatic treatment of mite allergy and specific subcutaneous immunotherapy (SCIT). METHODS Observational, retrospective, and multicenter study was carried out in Spain in 2013. The medical records of 419 patients diagnosed with rhinitis and/or bronchial asthma for mite allergy were retrieved. Mean age was 24.9 years (standard deviation 14.4). The use of symptomatic medication (rescue and daily), diagnostic tests, unscheduled medical care, and sick leave days associated with SCIT treatment versus no-SCIT treatment was compared. Also measured was the SCIT treatment to no-SCIT treatment costs ratio: used resources (symptomatic medication, unscheduled medical care, diagnostic tests, and 3 years SCIT treatment and sick leave days) were quantified in euros. Efficacy (decreased resource usage) of first-year treatment was assumed during the remaining 2 years and also during the 3-year follow-up period. RESULTS After a single year of SCIT, all quantified resources diminished significantly (P<0.05) from baseline. Estimated reduction in cost items included hospital resources (100% in hospitalizations, 82% in visits to the allergist, and 79% in emergency room visits), therapies (56% in rescue medication and 63% in daily medication), diagnostic tests (77%), and sick leave days (94%). Ratio of comparative calculation described as SCIT treatment versus non-SCIT treatment (or conventional symptomatic treatment) is 0.8. CONCLUSION Direct costs are reduced by 64% and indirect costs by 94%. SCIT of hypoallergenic preparation of dust mite (Acaroid(®)) allows cost savings versus conventional treatment. Estimated savings for the public National Health System are 5.7 times the cost of immunotherapy.

Abstract
Although house dust mite (HDM) allergy is a major cause of respiratory allergic disease, specific diagnosis and effective treatment both present unresolved challenges. Guidelines for the treatment of allergic rhinitis and asthma are well supported in the literature, but specific evidence on the efficacy of pharmacotherapy treatment for known HDM-allergic patients is weaker. The standard diagnostic techniques--skin prick test and specific IgE testing--can be confounded by cross-reactivity. However, component-resolved diagnosis using purified and recombinant allergens can improve the accuracy of specific IgE testing, but availability is limited. Treatment options for HDM allergy are limited and include HDM avoidance, which is widely recommended as a strategy, although evidence for its efficacy is variable. Clinical efficacy of pharmacotherapy is well documented; however, symptom relief does not extend beyond the end of treatment. Finally, allergen immunotherapy has a poor but improving evidence base (notably on sublingual tablets) and its benefits last after treatment ends. This review identifies needs for deeper physician knowledge on the extent and impact of HDM allergy in respiratory disease, as well as further development and improved access to molecular allergy diagnosis. Furthermore, there is a need for the development of better-designed clinical trials to explore the utility of allergen-specific approaches, and uptake of data into guidance for physicians on more effective diagnosis and therapy of HDM respiratory allergy in practice.

Abstract
Immunoglobulin E-mediated allergic responses to food and environmental allergens can cause symptoms ranging from mild allergic rhinitis and rashes to gastrointestinal distress and, most seriously, anaphylaxis. The diagnosis can be difficult, as it relies on complex interplay between patient history and diagnostic tests with low specificity. Adding to the difficulty in confirming the diagnosis is an increased public interest in food intolerances, which can be inappropriately attributed to an allergic response. Treatment of allergic diseases with avoidance strategies and pharmacologic treatments can improve quality of life and control of other chronic conditions, such as asthma and eczema.

Abstract
BACKGROUND Fluticasone furoate nasal spray (FFNS) is a glucocorticoid developed for the treatment of allergic rhinitis (AR). This is the first randomized clinical trial to assess the efficacy and safety of FFNS in Japanese children with perennial AR (PAR). METHODS In this multicentre, randomized, double-blind, placebo-controlled, parallel-group, phase III study, 261 children aged 6 to <15 years were treated with FFNS 55μg, once daily or placebo for two weeks. Nasal and ocular symptoms were rated by parents/guardians/patients in the patient daily diary. The primary endpoint was the mean change from baseline in the three total nasal symptom score (3TNSS). In addition, rhinoscopic findings were rated by the investigators as an efficacy measure. As a safety measure, adverse events and clinical chemistry and hematology were evaluated. RESULTS Mean change from baseline over the entire treatment period in 3TNSS was greater in the FFNS 55μg group compared with placebo, and the difference was statistically significant (p < 0.001). Significant improvements in rhinoscopic findings of swelling of inferior turbinate mucosa and quantity of nasal discharge were also observed. The total ocular symptom score (TOSS) was reduced significantly in the FFNS 55μg group, compared with placebo, in the second week in a subgroup of patients with baseline TOSS > 0. The incidence of adverse events was similar between FFNS 55μg(18%) and placebo (19%). CONCLUSIONS Two-week treatment with FFNS 55μg, once daily is effective and tolerable in Japanese children aged 6 to <15 years with PAR.

Clinical usefulness of a guideline-based screening tool for the diagnosis of allergic rhinitis in asthmatics: the Self Assessment of Allergic Rhinitis and Asthma questionnaire. Respirology 2014; 18:1016-21. [PMID: 23668782 DOI: 10.1111/resp.12116] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2012] [Revised: 01/03/2013] [Accepted: 01/29/2013] [Indexed: 12/01/2022]
Abstract
BACKGROUND AND OBJECTIVE Allergic rhinitis (AR) is common in asthmatic patients and may impair asthma control. However, this comorbidity is frequently missed. A simple test is needed to enable physicians to diagnose and evaluate the severity of both diseases. The Self Assessment of Allergic Rhinitis and Asthma (SACRA) questionnaire, which GINA and ARIA Japan committees developed in 2011, consist of questionnaires based on GINA and ARIA guidelines for the diagnosis and severity of AR and asthma, and a visual analogue scale (VAS) to evaluate the severity of both diseases. Our objective was to investigate the clinical usefulness of SACRA as a patient-based screening tool for identifying asthmatic patients with AR. METHODS SACRA, ACT (Asthma Control Test) and serum IgE RAST were performed in asthmatic patients. The correlation between SACRA and other parameters were analyzed. RESULTS Four hundred twenty asthmatic patients were enrolled. Among 168 subjects who self-reported no concomitant AR, 76 asthmatics scored one or more symptoms on SACRA. Eventually, 32 of these 76 subjects were diagnosed with AR by physicians based on laboratory data or physical examinations by ear, nose and throat specialists. The sensitivity and specificity of SACRA for the diagnosis of AR were 92% and 66%, respectively. The estimated prevalence of AR among asthmatics was 66%, almost identical to that of the previous nationwide study in Japan. The level of asthma control assessed by the VAS on SACRA and the ACT score showed a strong correlation (r = -0.700, P < 0.001). CONCLUSIONS SACRA may be a clinically useful tool for identifying bronchial asthma patients with AR.

Abstract
INTRODUCTION An association between pollen count (Poaceae) and symptoms is well known, but to a lesser degree the importance of priming and lag effects. Also, threshold levels for changes in symptom severity need to be validated. The present study aims to investigate the relationship between pollen counts, symptoms and health related quality of life (HRQL), and to validate thresholds levels, useful in public pollen warnings. MATERIAL AND METHODS Children aged 7-18 with grass pollen allergy filled out a symptom diary during the pollen season for nose, eyes and lung symptoms, as well as a HRQL questionnaire every week. Pollen counts were monitored using a volumetric spore trap. RESULTS 89 (91%) of the included 98 children completed the study. There was a clear association between pollen count, symptom severity and HRQL during the whole pollen season, but no difference in this respect between early and late pollen season. There was a lag effect of 1-3 days after pollen exposure except for lung symptoms. We found only two threshold levels, at 30 and 80 pollen grains/m(3) for the total symptom score, not three as is used today. The nose and eyes reacted to low doses, but for the lung symptoms, symptom strength did hardly change until 50 pollen grains/m(3). CONCLUSION Grass pollen has an effect on symptoms and HRQL, lasting up to 5 days after exposure. Symptoms from the lungs appear to have higher threshold levels than the eyes and the nose. Overall symptom severity does not appear to change during the course of season. Threshold levels need to be revised. We suggest a traffic light model for public pollen warnings directed to children, where green signifies "no problem", yellow signifies "can be problems, especially if you are highly sensitive" and red signifies "alert - take action".

Abstract
BACKGROUND Allergic rhinitis (AR) is a symptomatic disorder of the nose induced after allergen exposure by an IgE-mediated inflammation of the nasal mucosa. This study was designed to investigate the role of nasal mucosa temperature in AR. METHODS We investigated the relationship between eosinophilic infiltration, nasal obstruction, and nasal mucosa temperature in 35 children with rhinitis aged 6-12 years. RESULTS A significant relationship was shown between nasal temperature values and eosinophil infiltration at nasal cytology (p < 0.01). Nasal temperature was also significantly associated with nasal obstruction, assessed in terms of nasal volume (Vol [2-5 cm]; p < 0.05) and minimum cross-sectional area (p < 0.01). No significant correlation emerged between the degree of nasal obstruction and presence of eosinophils at nasal cytology (p > 0.05). CONCLUSION These results suggest a relationship between nasal temperature and nasal mucosa inflammation and obstruction.

Abstract
BACKGROUND The proportion of patients visiting general practitioners (GPs), otorhinolaryngologists (ORLs), and allergologists (ALRGs) for nasal complaints is unknown but important in estimating the number of subjects with nasal symptoms bothersome enough to warrant physician consultations and assessing nasal pathological conditions' burden on a national health care system. OBJECTIVE The Symptoms of Nasal Inconvenience Fact Finding (SNIFF) survey was developed to (1) assess incidence of physician visits attributable to nasal complaints; (2) characterize patients' nasal conditions; and (3) outline differences across physician categories. METHODS The SNIFF survey was completed over 20 days by Bulgarian GPs, ORLs, and ALRGs whom patients consulted for nasal symptoms. Survey forms differentiated type and severity of patients' conditions according to Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines and ranked bothersome symptoms. Smell impairment, comorbidities, and prescription practices were documented. RESULTS Sixty-nine physicians (30 GPs, 8 ORLs, 31 ALRGs) completed 1,685 surveys. The proportion of patients with nasal symptoms over the total patients seen was 15.7%: ALRGs, 18.0%; GPs, 14.6%; ORLs, 13.1%. Patients were classified as having intermittent (38.8%) or persistent (61.2%) rhinitis, with most having moderate/severe symptoms (94.4%). Congestion was the leading symptom in 59.1%. Smell was impaired in 69.8% of patients, asthma was present in 21.4%, and cough in 62.9%. ALRGs were more likely to diagnose and manage patients per ARIA guidelines than were ORLs or GPs. CONCLUSION The SNIFF survey results demonstrate congestion's role as a leading symptom motivating patients to seek medical advice. SNIFF also uncovered differences in practices among different categories of health care providers.

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

Abstract
The need for routine determination of rhinitis subtypes by allergy testing and the relevance between symptoms and allergy were evaluated. A retrospective study at a tertiary hospital, ENT clinic. One hundred and twenty-seven adult patients with sneezing and runny nose for at least 6 months for the last two consecutive years were included. The age range was 16-60. Allergy testing was only positive in 43.4% of the patients. Excluding mixed rhinitis, persistent sneezing and runny nose were mostly related to anatomical deformities, mainly septal deviation followed by vasomotor rhinitis. Persistent sneezing and runny nose may be caused by different etiologies other than allergy. Determination of rhinitis subtypes is important for accurate treatment of patients with these symptoms. Taking appropriate medical history and performing a good physical exam with objective allergy testing are highly recommended.

Abstract
The US FDA has issued safety alerts and required manufacturers of leukotriene-modifying agents (LTMAs), including montelukast, zafirlukast and zileuton, to include suicide and neuropsychiatric events as a precaution in the drug label. This paper reviews the existing evidence on the potential association between the LTMAs and suicidal behaviour. We conducted a literature search of MEDLINE, EMBASE and International Pharmaceutical Abstracts from 1995 to 2010 (inclusive) to identify pertinent studies and reports. We also examined data obtained from the FDA adverse event reporting system. To date, there are no well conducted, comparative, observational studies of this association, and the safety alerts are based primarily on case reports. While the FDA safety alerts apply to all three LTMAs, montelukast (known by its trade name Singulair®) is by far the most widely used of these drugs and most of the reports to date regarding suicide pertain to montelukast. From 1998 to 2009 there were 838 suicide-related adverse events associated with leukotrienes reported to the FDA, of which all but five involved montelukast. Nearly all cases were reported in 2008 and 2009 (96.1%) after the FDA warnings. LTMAs are approved for use in asthma and allergic rhinitis, and are effective drugs. Both of these diseases are also associated with suicide, making confirmation of the association more difficult. Given the lack of good evidence, we recommend that a large observational cohort or case-control study be conducted to quantify the association between LTMAs and suicide. Until then, when prescribing LTMAs, clinicians should consider the potential for suicide and monitor patients who may be at elevated risk carefully for suicidal ideation or psychiatric symptoms associated with suicidal behaviour.

Abstract
In contrast to symptomatic drug treatment, which only temporarily relieves allergy symptoms, allergen-specific immunotherapy (SIT) has the potential to alter the course of allergic disease, thereby reducing the need for long-term treatment, the progression of allergic rhinitis (AR) to asthma, and the development of new allergies. The clinical benefits of SIT have been shown to persist for an additional 3 to 12 years after discontinuation of a 2.5- to 5.0-year treatment. It therefore stands to reason that the clinical benefits of SIT also extend to economic benefits. A growing number of studies have evaluated the economic benefits of SIT in patients with AR and/or asthma. The authors critically examine each of these studies published from 1995 to present.

Abstract
AIM The aim of the study was to translate and validate the PADQLQ (Pediatric Allergic Disease Quality of Life Questionnaire), a disease-specific quality of life questionnaire for the assessment of quality of life in children with pollen allergy. METHODS The PADQLQ was translated into Swedish according to guidelines. Children aged 7-18 with grass pollen allergy were included. Quality of life was assessed in parallel with ordinary symptom scales (VAS) before, during and after the pollen season. RESULTS A total of 98 children were included and 89 (91%) completed the study. The results for PADQLQ showed good cross-sectional and longitudinal validity. The retrospective estimation after the season showed good consensus with the assessment during pollen season. CONCLUSION Quality of life in children assessed with the PADQLQ (Pediatric Allergic Disease Quality of Life Questionnaire) is a reliable strategy for evaluating the burden of disease in children with pollen allergy and for the evaluation of treatment.

Abstract
Oxidative stress is considered as a major risk factor that contributes to increased lipid peroxidation and declined antioxidants in some degenerative diseases. Glycyrrhizin is widely used to cure allergic diseases due to its medicinal properties. In the present study, we evaluated the role of glycyrrhizin on lipid peroxidation and antioxidant status in the blood and nasal mucosa of allergic rhinitis (AR) mice. Mice were divided into six groups: normal control mice, model control (MC) mice, three glycyrrhizin-treated mice groups and lycopene-treated mice. Sensitization-associated increase in lipid peroxidation was observed in the blood and nasal mucosa of MC mice. Activities of antioxidant enzymes like superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), total antioxidant capacity (TAOC) and levels of glutathione (GSH) were found to be significantly decreased in the blood and nasal mucosa in MC mice when compared to normal control mice. However, normalized lipid peroxidation and antioxidant defenses were reported in the glycyrrhizin-treated and lycopene-treated mice. Moreover, glycyrrhizin treatment still enhanced IFN-γ and reduced IL-4 levels in glycyrrhizin-treated mice. These findings demonstrated that glycyrrhizin treatment enhanced the antioxidant status and decreased the incidence of free radical-induced lipid peroxidation and improved immunity activities in the blood and nasal mucosa of AR mice.

Abstract
OBJECTIVE It is hypothesised that the presence of ocular, in addition to nasal, symptoms among patients with allergic rhinitis (AR) results in poorer quality of life, reduced work productivity and increased resource utilisation. This study investigated the impact on quality of life, burden of illness and healthcare resources among 1640 AR patients. METHODS Data were drawn from an observational cross-sectional study of consulting patients undertaken in May/June 2008 in four European countries. Doctors provided records for the next four to five patients presenting with AR who filled out a self-completion survey which included the Work Productivity and Activity Impairment Allergic Specific Questionnaire (WPAI:AS), the Mini Rhinoconjunctivitis Quality of Life Questionnaire (RQOLQ) and the Pittsburgh Sleep Quality Index (PSQI). Propensity scoring allied to regression-type analysis was used to assess the extra burden associated with ocular symptoms utilising two comparison groups (patients with nasal-only symptoms versus those with nasal and ocular symptoms). The analysis controlled for differences between the groups on confounding variables age, gender, smoking status and co-morbidities. The analysis was conducted twice, once controlling for differences between the groups in nasal severity and once without, recognising that it is not clear whether or not increased nasal severity symptoms are naturally associated with ocular symptoms. The severity of ocular symptoms as opposed to their presence alone was also assessed on outcome measures using regression type methods. RESULTS A total of 1009 patient records met the inclusion criteria, of whom 69% presented with both ocular and nasal symptoms. The results show that the presence of ocular symptoms reduces quality of life, reduces work productivity and increases resource utilisation irrespective of whether differences in severity of nasal symptoms are accounted for between the comparison groups. Patients with nasal and ocular symptoms require more healthcare consultations. All work-related domains were statistically different, with the presence of ocular symptoms associated with greater impact on work hours missed and impairment while working. For each of the above this was the case regardless of whether or not adjustment was made for nasal severity (both p < 0.05). Patients with nasal and ocular symptoms also record an additional half a day more time off work in the last 3 months as a result of AR (nasal severity unadjusted or adjusted, both p < 0.05). Clinically meaningful differences were found in overall quality of life score as represented by RQLQ, with a mean score increase of 0.6 (nasal severity unadjusted) and 0.5 (nasal severity adjusted) associated with the presence of ocular symptoms (both p < 0.05). With regard to sleep quality, the presence of ocular symptoms was associated with a mean increase in PSQI of 1 when no adjustment was made for nasal severity (p < 0.05). When nasal severity was adjusted for, no significant difference was observed. Similarly, for the number of prescribed medications, when no adjustment was made for nasal severity, patients with ocular symptoms were observed to receive a significantly higher number of AR drugs (+0.19, p < 0.05) whereas with nasal severity adjusted for the difference was +0.17 which was not significant. In addition, with the exception of the number of AR drugs prescribed, for all outcome variables, the severity of ocular symptoms, and not just their presence, had a detrimental impact on the outcome. LIMITATIONS Since patients were recruited via the physician, the study aim was to represent the consulting population. In addition, it cannot be fully excluded that the likelihood for an individual patient to complete a questionnaire is influenced by differences in patient typology compared with those patients who chose not to complete. Given the geographical dispersion of the sample patients, it may be reasonable to assume possible differences in the intensity of the AR season based on latitude. CONCLUSION The added presence of ocular symptoms in AR patients suffering with nasal symptoms deteriorates patients' quality of life, leads to greater lost productivity and places higher burden on resource utilisation. Studies are therefore needed to test whether treatment options that address ocular in addition to nasal symptoms will improve quality of life and reduce both direct and indirect resource use associated with AR.

Abstract
OBJECTIVE Obstructive sleep apnea syndrome (OSAS) is commonly associated with adenotonsillar hypertrophy. We hypothesized that respiratory perturbations extend to other regions of the upper respiratory tract in such children, particularly to rhino-sinus regions. STUDY DESIGN A prospective case control study using Magnetic Resonance Imaging (MRI) of the upper airway and surrounding tissues of OSAS and controls. Magnetic resonance imaging was used to evaluate radiographic changes within the: paranasal sinuses, middle ear and mastoid air cells, and the nasal passages. RESULTS We studied 54 OSAS (age 5.7 ± 3.0 years) and 54 controls (age 6.2 ± 2.0 years, P = NS). Children with OSAS had significantly more opacification of: maxillary sinuses (P < 0.05), sphenoid sinuses (P < 0.01), and mastoid air cells (P < 0.01). They also had significantly more: middle ear effusions, (P < 0.001), prominence of inferior nasal turbinate(s) (P < 0.05), and deviation of the nasal septum (P < 0.05). CONCLUSIONS Childhood OSAS is associated with a wide range of upper respiratory tract perturbations and is not limited to adenoid and tonsillar hypertrophy.

Abstract
BACKGROUND Children with allergic rhinitis (AR) often experience significant impairment in quality of life and health, which increases health care utilization. OBJECTIVE To determine whether allergen immunotherapy reduces health care utilization and costs in children newly diagnosed as having AR using a retrospective matched cohort design. METHODS Among children (age <18 years) with a Florida Medicaid paid claim between 1997 and 2007, immunotherapy-treated patients were selected who had newly diagnosed AR, who had not received immunotherapy before their first (index) AR diagnosis, who had received at least 2 immunotherapy administrations after their index AR diagnosis, and who had at least 18 months of data after their first immunotherapy administration. A control group of patients with newly diagnosed AR who had not received immunotherapy either before or subsequent to their index AR diagnosis also were identified, and up to 5 were matched with each immunotherapy-treated patient by age at first AR diagnosis, sex, race/ethnicity, and diagnosis of asthma, conjunctivitis, or atopic dermatitis. RESULTS Immunotherapy-treated patients had significantly lower 18-month median per-patient total health care costs ($3,247 vs $4,872), outpatient costs exclusive of immunotherapy-related care ($1,107 vs $2,626), and pharmacy costs ($1,108 vs $1,316) compared with matched controls (P < .001 for all). The significant difference in total health care costs was evident 3 months after initiating immunotherapy and increased through study end. CONCLUSIONS This study demonstrates the potential for early and significant cost savings in children with AR treated with immunotherapy. Greater use of this treatment in children could significantly reduce AR-related morbidity and its economic burden.

Abstract
BACKGROUND Many patients with allergic rhinitis are reluctant to use daily intranasal steroids for prolonged periods. A self-adjusted regimen which delivers reasonable control of allergic rhinitis may be more acceptable to such patients. OBJECTIVES To compare the efficacy of daily use of mometasone furoate nasal spray, versus a self-adjusted regimen, in patients with chronic allergic rhinitis, in terms of symptom control and nasal volume change. SETTING Ambulatory visits in an office setting. PATIENTS AND METHODS Sixty patients with chronic allergic rhinitis were randomised: 30 were prescribed mometasone furoate nasal spray once daily for six weeks, while 30 were prescribed the same spray daily for one week, every alternate day for one week and then on a self-adjusted regimen for four weeks. Patients kept a symptom diary documenting sneezing, rhinorrhoea, nasal blockage and nasal itching. Acoustic rhinometry was used to measure the total nasal cavity volume at the first visit and at the end of the treatment period. RESULTS The total nasal score on treatment days showed an improvement in both groups, compared with baseline measurements. There was no significant difference in total nasal scores between the two groups, except on days 10 (p = 0.043), 20 (p = 0.008), 23 (p = 0.19), 30 (p = 0.008) and 37 (p = 0.000), when the daily group's total nasal score was significantly lower than the self-adjusted group's total nasal score, and on day 8 (p = 0.004), when the self-adjusted group's total nasal score was significantly lower than the daily group's total nasal score. Total nasal cavity volume significantly increased in both groups (p = 0.0001), with no statistically significant difference between the groups. CONCLUSIONS Self-adjusted dosage of mometasone furoate nasal spray gives reasonable control of allergic rhinitis (albeit with some 'breakthrough' symptoms). Patients should learn how to control these symptoms with the least number of steroid doses.

Immunogenic yeast-based fermentation product reduces allergic rhinitis-induced nasal congestion: a randomized, double-blind, placebo-controlled trial. Adv Ther 2009; 26:795-804. [PMID: 19672568 DOI: 10.1007/s12325-009-0057-y] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2009] [Indexed: 12/28/2022]
Abstract
INTRODUCTION Allergic rhinitis (AR) impacts around 25% of the worldwide population. However, cost, safety, and a high dissatisfaction rate with numerous conventional medications continues to be an issue in the largest patient surveys, due primarily to a lack of efficacy on nasal congestion. Our previously published randomized trial demonstrated a significant reduction in cold and flu-like symptoms, and a secondary potential observation of a decrease in nasal congestion with an oral yeast-derived compound; therefore, the objective of this study was to test the effects of this same product on nasal congestion and other notable AR symptoms. METHODS A 12-week, randomized, double-blind, placebo-controlled clinical trial of 96 healthy subjects with a recent clinically documented history of seasonal allergies and AR was conducted. Participants received once-daily supplementation with 500 mg of a dried, modified Saccharomyces cerevisiae oral fermentation product (EpiCor, Embria Health Sciences, Ankeny, Iowa, USA) or placebo during the 12-week period of the highest recorded concentrations of total pollen counts for this Midwest geographic area. Clinical outcome measurements included in-clinic examinations, validated questionnaire and standard diary, and serologic analysis at baseline, 6 and 12 weeks. RESULTS During the highest pollen count period (weeks 1-6), EpiCor significantly reduced the mean severity of specific AR symptoms, including a significant reduction in nasal congestion (P=0.04), rhinorrhea (P=0.005), and a nonsignificant reduction in ocular discharge symptoms. A significantly (P=0.04) reduced total number of days with nasal congestion (12.5 fewer days) favored EpiCor compared with placebo, as did the nasal congestion section of the quality of life questionnaire (P=0.04). Subjects receiving the intervention also experienced significantly (P=0.03) higher salivary IgA levels. Adverse events were similar to placebo. CONCLUSION This yeast-derived product appeared to be safe and efficacious, and should receive more clinical research with and without standard medications to reduce the impact of seasonal allergies, especially AR-induced nasal congestion.

Abstract
UNLABELLED Allergic rhinitis is more than just sneezing and an itchy nose. Complications of this disease are numerous and can have a significant impact, both mentally and physically. That is why it is important not only to detect, investigate and treat allergic rhinitis but also to actively identify potential complications. Mental functions such as learning, sleep and activity levels can deteriorate, and the eustachian tubes, sinuses and airway functions can be affected. Otitis, sinusitis and asthma are overrepresented among individuals who suffer from allergic rhinitis. This article highlights how allergic rhinitis can affect cognitive functions, and what consequences this can have on school performance, work and quality of life. CONCLUSION Health professionals and school personnel need to increase their awareness of the ramifications of this disease and actively work to prevent deterioration in both academic achievement and workplace productivity.

Abstract
Childhood rhinitis may be classified into non-allergic and allergic. Allergic rhinitis is further divided into seasonal and perennial. Seasonal rhinitis is a disease particularly of teenagers and young adults and appears to be less common in primary and pre school age children. In seasonal rhinitis, with relevant grass pollen sensitization, the link between the allergen exposure and rhinitis is clear cut. However, in other situations such as perennial rhinitis and house dust mite allergen sensitization, the link between symptoms and allergen exposure is less certain. Avoidance of allergens often proves to be difficult in practice. Intranasal steroids are the treatment of choice for persistent moderate-severe allergic rhinitis and are more effective than antihistamines for relief of nasal obstruction. Antihistamines are effective for control of histamine related symptoms such as itching, rhinorrhoea and sneezing. The use and benefits of sublingual or injectable immunotherapy in children are controversial.
