To investigate the likelihood of allergic rhinitis and potential co-morbidities, and to assess whether allergic rhinitis is associated with arterial blood pressure and hypertension. In this population-based study, 369 adults with allergic rhinitis and asthma were assessed via a questionnaire and immunoglobulin E levels. There were four groups: control (n = 90), allergic rhinitis (n = 99), asthma (n = 87) and hypertension (n = 93). Arterial blood pressure was measured in all groups. There were no significant differences in systolic or diastolic blood pressure between males and females in any group. Pairwise comparisons revealed no significant differences between: the control and allergic rhinitis groups, the control and asthma groups, or the allergic rhinitis and asthma groups. The systolic and diastolic blood pressure values of males and females were significantly higher in the hypertension group than the allergic rhinitis group. There were no significant differences in systolic blood pressure or diastolic blood pressure for seasonal and perennial allergic rhinitis patients. Rhinitis was not associated with increased blood pressure. Allergic rhinitis can coincide with asthma and hypertension. The findings do not support the need for blood pressure follow up in allergic rhinitis patients.

Background Cesarean delivery may alter neonatal immune responses and increase the risk of atopy. Studies of the relation between cesarean delivery and allergic diseases in children not selected on the basis of a family history of atopy have yielded inconsistent findings. Objective To examine the relation between birth by cesarean delivery and atopy and allergic diseases in children at risk for atopy. Methods We examined the relation between mode of delivery and the development of atopy and allergic diseases among 432 children with parental history of atopy followed from birth to age 9 years. Asthma was defined as physician-diagnosed asthma and wheeze in the previous year and allergic rhinitis as physician-diagnosed allergic rhinitis and naso-ocular symptoms apart from colds in the previous year. Atopy was considered present at school age if there was >=1 positive skin test or specific IgE to common allergens. Stepwise logistic regression was used to study the relation between cesarean delivery and the outcomes of interest. Results After adjustment for other covariates, children born by cesarean section had twofold higher odds of atopy than those born by vaginal delivery (OR=2.1, 95% CI=1.1–3.9). In multivariate analyses, birth by cesarean section was significantly associated with increased odds of allergic rhinitis (OR=1.8, 95% CI=1.0–3.1) but not with asthma. Conclusions Our findings suggest that cesarean delivery is associated with allergic rhinitis and atopy among children with parental history of asthma or allergies. This could be explained by lack of contact with the maternal vaginal/fecal flora or reduced/absent labor during cesarean delivery. Clinical Implications Potential development of allergic diseases should be considered as a potential risk of cesarean delivery among children with parental history of atopy. Capsule Summary Cesarean delivery may lead to an increased risk of allergic rhinitis and atopy in children with parental history of atopy. PMID

Allergic rhinitis is a complex polygenic disorder of the upper respiratory tract. Given that proinflammatory cytokines such as tumor necrosis factor (TNF) and interleukin (IL) 1 seem to play a role in the development of allergic rhinitis, we evaluated the associations between various single-nucleotide polymorphisms (SNPs) of the TNF and IL1 genes in a case-control study. The study population comprised 98 patients with allergic rhinitis. Genotyping was performed using polymerase chain reaction with sequence-specific primers for 2 TNFA promoter variants (rs1800629 and rs361525), 1 variant in the promoter region of IL1A (rs1800587), 2 SNPs in the IL1B gene (rs16944 and rs1 143634), 1 variant in the IL1 receptor (rs2234650), and 1 in IL1RA (rs315952). Patients who were homozygous for the T allele of rs16944 in IL1B had an 8.1-fold greater risk of allergic rhinitis than those with the C allele. In TNFA, a significant relationship was also detected between rs1800629 and rs361525 and allergic rhinitis. Except for rs1800587 in IL1A and rs315952 in IL1RA, significant differences were found between the patient and control groups for all other SNPs. We found that allelic variants in the TNFA and IL1 genes were not only associated with the risk of developing allergic rhinitis, but also affected disease course and severity.

Results of epidemiologic studies have determined several risk factors for asthma in school-age children. To examine whether parental and perinatal risk factors, along with infantile feeding patterns, were associated with asthma in children with grass pollen allergy and allergic rhinitis. We retrospectively analyzed the data of our cohort, which consisted of children with allergic rhinitis. Only children with grass pollen sensitization were enrolled. A detailed questionnaire regarding demographic features and perinatal events was given to the parents. A total of 293 children (200 boys [68.3%]; with median age, 10.2 years [interquartile range {IQR}, 7.4-13.0 years]) were included. A total of 109 children (37.2%) had accompanying asthma. The median age of onset of rhinitis symptoms was earlier (5.3 years [IQR, 4.0-8.0 years] versus 7.0 years [IQR, 5.0-10.0 years]; p = 0.001), histories of prematurity (16.7 versus 6.5%; p = 0.006), preeclampsia (5.5 versus 0%; p = 0.001), neonatal intensive care unit admission (15.1 versus 6.0%; p = 0.01), phototherapy (17.9 versus 7.1%; p = 0.004), early formula feeding (58.7 versus 41.2%; p = 0.006), and parental asthma (25.0 versus 11.4%; p = 0.002) were more frequent in children with asthma. Multivariate logistic regression analysis revealed prematurity (odds ratio [OR] 2.78 [95% confidence interval [CI],1.24-6.24]; p = 0.013), history of formula feeding (OR 1.81 [95% CI, 1.09-3.01]; p = 0.022), and parental asthma (OR 2.37 [95% CI, 1.22-4.63]; p = 0.011) were associated with asthma in school-age children with grass pollen-induced allergic rhinitis. Close monitoring of patients with these risk factors may help with an earlier diagnosis of asthma and prompt initiation of therapeutic interventions in children with allergic rhinitis and who were sensitized to grass pollen.

The aim of this study was to evaluate the prevalence of allergic rhinitis and its relationship with various risk factors in 6-7-year-old children living in İstanbul. A total of 11,483 children aged 6-7 years in 75 primary schools from all districts of İstanbul were surveyed. Prevalence of symptoms of allergic rhinitis was assessed using a translated version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Of them, 9,875 (50.7% M, 49.3% F) questionnaires were appropriately completed by the parents. The prevalence rates of lifetime, current and physician-diagnosed allergic rhinitis were 44.3%, 29.2% and 8.1%, respectively. There was nearly a two-fold variation in the prevalence rates of rhinitis between the districts of İstanbul. Frequent paracetamol and antibiotic use in the first year of life, history of frequent upper respiratory tract infections, adenotonsillectomy, breastfeeding less than six months, dog at home or perianal redness in the first year of life, and frequent trucks passing near the home were independent risk factors.

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.

Disturbed sleep: linking allergic rhinitis, mood and suicidal behavior.

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.

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.

Allergic rhinitis has become the most frequent chronic disease of upper airways and its prevalence is increasing importantly in countries with systems of western life. To determine the prevalence of allergic rhinitis and its subtypes in inhabitants of Durango, Mexico. Through a descriptive, cross-sectional study, 1,320 inhabitants of Durango were studied. They were chosen randomly and accepted voluntarily to participate. A modification of the Middleton diary symptom questionnaire was used as a tool to determine the prevalence. The prevalence of allergic rhinitis in the general population was of 7.6% (95% CI 6.2-9.2). The prevalence of seasonal rhinitis was of 5.5% (95% CI 4.4-6.9), of perennial rhinitis, 2.1% (95% CI 1.4-3.0), for medical diagnosis, 4.3% (95% CI 3.4-5.8), and for survey, 3.3% (95% CI 2.4-4.4). The highest frequency was found in persons of 5-9 years old (12.5%) and in women (5.1%). The prevalence of allergic rhinitis in Durango, Mexico, is similar to the national mean prevalence, but lower than that reported in developed countries.

To create an allergic disease risk factors scale score that would screen for the risk assessment of asthma, allergic rhinitis and atopic dermatitis in children from 3-17 years. This case-control study, conducted between December 2015 and April 2016, enrolled 1274 children. The allergic disease risk factors scale was created by combining environmental, exposure to toxics during pregnancy and breastfeeding and parental history of allergic diseases. Playing on carpets, male gender, child's respiratory problems or history of eczema before the age of 2 years, and humidity significantly increased the odds of allergies in the child. Maternal waterpipe smoking, maternal history of rhinitis, history of asthma in the mother or the father, along with the maternal drug intake or alcohol consumption during pregnancy significantly increased the odds of allergies in the child. There was a significant increase in allergy diseases per category of the allergic disease risk factors scale (p < 0.001 for trend). Scores ≤ 2.60 best represented control individuals, while scores > 5.31 best represented children with allergic diseases. Allergic diseases seem to be linked to several risk factors in our population of school children. Many environmental factors might be incriminated in these allergic diseases. ©2018The Author(s).

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. 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.

Previous studies have suggested an immunological dysfunction in bipolar disorder, but none has investigated the temporal association between allergic rhinitis (AR) and bipolar disorder. Using Taiwan National Health Insurance Research Database, 9506 adolescents aged 12-18 years with allergic rhinitis were enrolled between 2000 and 2008 and compared to 38,024 age-and gender-matched (1:4) control groups. Subjects of bipolar disorder that occurred up to the end of follow-up (December 31, 2011) were identified. Adolescents with AR had a significantly higher incidence of developing bipolar disorder (0.77 vs. 0.18 per 1000 person-years, p<0.001) during the follow-up period than the controls. Adolescents with AR had an increased risk (hazard ratio [HR]: 4.62, 95% confidence interval [CI]: 3.17-6.75) of developing bipolar disorder in their later life compared to the control group after adjusting for demographic data and comorbid allergic diseases. This is the first study showing a temporal association between AR and bipolar disorder, in that patients who had AR in adolescence exhibited an increased risk of developing bipolar disorder in later life. Further study would be required to investigate the underlying mechanism about this association. Copyright © 2015 Elsevier Inc. All rights reserved.

Background Allergic rhinitis is the most common type of allergy worldwide. The accuracy of skin testing for allergic rhinitis is still debated. This health technology assessment had two objectives: to determine the diagnostic accuracy of skin-prick and intradermal testing in patients with suspected allergic rhinitis and to estimate the costs to the Ontario health system of skin testing for allergic rhinitis. Methods We searched All Ovid MEDLINE, Embase, and Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, CRD Health Technology Assessment Database, Cochrane Central Register of Controlled Trials, and NHS Economic Evaluation Database for studies that evaluated the diagnostic accuracy of skin-prick and intradermal testing for allergic rhinitis using nasal provocation as the reference standard. For the clinical evidence review, data extraction and quality assessment were performed using the QUADAS-2 tool. We used the bivariate random-effects model for meta-analysis. For the economic evidence review, we assessed studies using a modified checklist developed by the (United Kingdom) National Institute for Health and Care Excellence. We estimated the annual cost of skin testing for allergic rhinitis in Ontario for 2015 to 2017 using provincial data on testing volumes and costs. Results We meta-analyzed seven studies with a total of 430 patients that assessed the accuracy of skin-prick testing. The pooled pair of sensitivity and specificity for skin-prick testing was 85% and 77%, respectively. We did not perform a meta-analysis for the diagnostic accuracy of intradermal testing due to the small number of studies (n = 4). Of these, two evaluated the accuracy of intradermal testing in confirming negative skin-prick testing results, with sensitivity ranging from 27% to 50% and specificity ranging from 60% to 100%.

Allergic rhinitis is estimated to affect as many as 40 million people in the United States on a regular basis, and even more individuals who have occasional symptoms. The disease is associated with a considerable burden on the healthcare system, accounting for a total of $7.9 billion in direct and indirect costs in 1997, and with significant adverse effects on patients' quality of life, including disturbed sleep and impaired function at work and school. The pathophysiology of allergic rhinitis is complex, involving inflammatory mediators and immune cells that produce allergy symptoms via multiple mechanisms. The first principle of clinical management of patients with allergic rhinitis is avoidance of exposure to allergens, but this measure can be very difficult, and most patients require pharmacotherapy. Allergy vaccine therapy may be an appropriate and necessary option in selected patients with allergies refractory to other treatment modalities.

The cost of productivity losses associated with allergic rhinitis.

To measure the cost of absenteeism and reduced productivity associated with allergic rhinitis. The National Health Interview Survey (NHIS) was used to obtain information on days lost from work and lost productivity due to allergic rhinitis. Wage estimates for occupations obtained from the Bureau of Labor Statistics (BLS) were used to calculate the costs. Productivity losses associated with a diagnosis of allergic rhinitis in the 1995 NHIS were estimated to be $601 million. When additional survey information on the use of sedating over-the-counter (OTC) allergy medications, as well as workers' self-assessments of their reduction in at-work productivity due to allergic rhinitis, were considered, the estimated productivity loss increased dramatically. At-work productivity losses were estimated to range from $2.4 billion to $4.6 billion. Despite the inherent difficulty of measuring productivity losses, our lowest estimate is several times higher than previous estimates of the indirect medical costs associated with allergic rhinitis treatment. The most significant productivity losses resulted not from absenteeism but from reduced at-work productivity associated with the use of sedating OTC antihistamines.

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. © 2015 John Wiley & Sons A/S.

Bilastine as a potential treatment in allergic rhinitis.

PubMed

Kowal, Krzysztof; DuBuske, Lawrence

2014-01-01

Allergic rhinitis is a very frequent disease. H1 antihistamines have been used for treatment of allergic rhinitis for more than 5 decades. They differ in chemical structure, pharmacokinetics, pharmacodynamics, clinical efficacy and adverse effects. We performed a detailed analysis of all available publications concerning the new H1-antihistamine bilasitine. Bilastine, a piperidine derivative, is a novel potent H1 antihistamine. It is at least as potent as cetirizine or fexofenadine in in vitro studies. In animal studies it demonstrates dose-dependent antihistaminic and antiallergic effects. In humans its metabolism is not affected by age, gender or renal function but may be affected by coadministration of P glycoprotein inhibitors. Efficacy of bilastine in therapy of allergic rhinitis patients has been documented in several large controlled clinical trials showing bilastine being at least as effective as cetirizine or desloratadine. No significant suppressive effect on central nervous system could be demonstrated when bilastine was used in the recommended doses. Bilastine is a novel H1 antihistamine with anti-allergic properties which is highly effective in the treatment of symptoms of allergic rhinitis. It has a favorable pharmacokinetic and pharmacodynamic profile and is generally well tolerated.

Allergic rhinitis is considered to be a major health problem that impairs quality of life. A possible relationship with psychological stress may exist. The aim of this study is to verify the relationship between persistent allergic rhinitis (PAR) and psychological stress aiming to improve treatment and thereby quality of life (QOL) of patients. Patients with PAR (166) were diagnosed then analyzed using the Kessler Psychological Distress Scale. Patients with allergic rhinitis and who were positive on the Kessler scale (122) were randomly divided equally into a control group which received levocetirizine and a study group which received levocetirizine and imipramine. Nasal symptom assessment and QOL assessment were performed in all patients after treatment. Of the 166 patients with PAR, 122 (73.5 %) were positive on the Kessler Psychological Distress Scale. There was a marked improvement in the study group compared with the control group as regards nasal symptoms with better QOL in the study group (6.93) compared with the control group (2.13). Psychological stress has a strong impact on persistent allergic rhinitis. When stress is controlled by a combined treatment of imipramine and levocetirizine, allergic rhinitis symptoms improved and a better QOL was obtained. 3b.

Background Associations of filaggrin (FLG) variants with asthma and rhinitis have been shown to be modulated by eczema status. However, it is unknown whether allergic sensitization status modifies this association. The aim of this study was to determine whether FLG variants need eczema and/or allergic sensitization as a necessary component to execute its adverse effect on coexisting and subsequent asthma and rhinitis. Methods Repeated measurements of asthma, rhinitis, eczema, and allergic sensitization (documented by skin prick tests) at ages 1, 2, 4, 10, and 18 years were ascertained in the Isle of Wight birth cohort (n = 1,456). FLG haploinsufficiency was defined as having at least the minor allele of R501X, 2282del4, or S3247X variants. Log binomial regression models were used to test associations and statistical interactions. Results FLG variants increased the risk of asthma (RR = 1.39, 95% CI: 1.06 – 1.80) and rhinitis (RR = 1.37, 95% CI: 1.16 – 1.63). In delayed effect models, ‘FLG variants plus allergic sensitization’ and ‘FLG variants plus eczema’ increased the risk of subsequent asthma by 4.93-fold (95% CI: 3.61 – 6.71) and 3.33-fold (95% CI: 2.45 – 4.51), respectively, during the first 18 years of life. In contrast, neither eczema nor allergic sensitization in combination with FLG variants increased the risk of later rhinitis. Conclusions Allergic sensitization and eczema modulated the association between FLG variants and asthma, but not rhinitis. Results of our study imply that the mechanisms and pathways through which FLG variants predispose to increased risk of asthma and rhinitis may be different. PMID:25277085

Objective To explore the association of allergic rhinitis with the use of pesticides among grape farmers in Crete. Methods A cross‐sectional study of 120 grape farmers and 100 controls at the Malevisi region in Northern Crete was conducted. The protocol consisted of a questionnaire, skin prick tests for 16 common allergens, measurement of specific IgE antibodies against 8 allergens, and spirometry before and after bronchodilatation. Results Grape farmers who used pesticides had higher prevalence rates of allergic rhinitis symptoms (OR, 3.0; 95% CI, 1.4 to 6.2) compared with grape farmers who reported no current use of pesticides, and control subjects. Logistic regression models controlling for age, sex and smoking status showed that 6 of the 12 predefined groups of major pesticides were significantly related to allergic rhinitis symptoms. The highest risks were observed for paraquat and other bipyridyl herbicides (OR, 2.2; 95% CI, 1.0 to 4.8), dithiocarbamate fungicides (OR, 2.5; 95% CI, 1.1 to 5.3) and carbamate insecticides (OR, 3.0; 95% CI, 1.4 to 6.5). A factor analysis of pesticides used identified 3 distinct factors. The most common factor was that of multiple pesticide use that included 9 pesticides and was significantly associated with allergic rhinitis (OR, 1.5; 95% CI, 1.0 to 2.3). ORs were higher when allergic rhinitis was defined using both questionnaire data on symptoms and atopy. Conclusions Occupational exposure to multiple agricultural chemicals could be related to allergic rhinitis in grape farmers. PMID:17182637

Since pathophysiologic evidence has been raised to suggest that obesity could facilitate an allergic reaction, obesity has been known as an independent risk factor for allergic disease such as asthma. However, the relationship between sedentary behavior and lifestyle which could lead to obesity, and those allergic diseases remains unclear. We analyzed the relations between physical activity, including sitting time for study, sitting time for leisure and sleep time, and obesity, asthma, allergic rhinitis, and atopic dermatitis using the Korea Youth Risk Behavior Web-based Survey, which was conducted in 2013. Total 53769 adolescent participants (12 through 18 years old) were analyzed using simple and multiple logistic regression analyses with complex sampling. Longer sitting time for study and short sitting time for leisure were associated with allergic rhinitis. High physical activity and short sleep time were associated with asthma, allergic rhinitis, and atopic dermatitis. Underweight was negatively associated with atopic dermatitis, whereas overweight was positively correlated with allergic rhinitis and atopic dermatitis. High physical activity, and short sleep time were associated with asthma, allergic rhinitis, and atopic dermatitis. © Copyright: Yonsei University College of Medicine 2017

Allergic rhinitis is a common inflammatory nasal mucosal disease characterized by sneezing, watery nasal discharge, nasal obstruction and itching. Although allergen-specific antibodies play a main role in the allergic airway inflammation, neuronal inflammation may also contribute to the symptoms of allergic rhinitis. Neuronal inflammation is primarily caused by the stimulation of sensory nerve endings with histamine. It has been shown that neurotrophins may also have a role in allergic reactions and neuronal inflammation. Nerve growth factor, neurotrophin 3 (NT-3), neurotrophin 4/5 and brain-derived neurotrophic factor are members of the neurotrophin family. Although nerve growth factor and brain-derived neurotrophic factor are well studied in allergic rhinitis patients, the exact role of Neurotrophin-3 is not known. To investigate the possible roles of neurotrophin-3 in allergic rhinitis patients. Case-control study. Neurotrophin-3 levels were studied in the inferior turbinate and serum samples of 20 allergic rhinitis and 13 control patients. Neurotrophin-3 staining of nasal tissues was evaluated by immunohistochemistry and ELISA was used for the determination of serum Neurotrophin-3 levels. Neurotrophin-3 staining scores were statistically higher in the study group than in the control patients (p=0.001). Regarding serum Neurotrophin-3 levels, no statistically significant difference could be determined between allergic rhinitis and control patients (p=0.156). When comparing the serum NT-3 levels with tissue staining scores, there were no statistically significant differences in the allergic rhinitis and control groups (p=0.254 for allergic rhinitis and p=0.624 for control groups). We suggest that Neurotrophin-3 might affect the nasal mucosa locally without being released into the systemic circulation in allergic rhinitis patients.

Allergic rhinitis is an inflammatory disorder of the nasal mucosa, characterized by symptoms of itching, rhinorrhea, nasal congestion and sneezing induced by an IgE-mediated response. In Mexico we have reports of prevalence, with fluctuations of 5.5% to 47.7% with the question of rhinitis symptoms the past 12 months. To determine the prevalence of allergic rhinitis in schoolchildren from various states of Mexico. A descriptive study of prevalence in which a questionnaire was applied to preschool, elementary-, middle- and high-school population. It was performed in four cities in four states of Mexico: Puebla, Puebla, Tulancingo, Hidalgo, Tlaxcala, Tlaxcala and Cancun, Quintana Roo. Parents answered questionnaires of preschool and elementary school and middle- and high-school students answered their questionnaires. The study was conducted from June 2014 to January 2015. The instrument used was: questionnaire diagnosis of allergic rhinitis for epidemiological studies. Of the surveys, 8,159 completed questionnaires were obtained, in the city of Puebla: 2,267, Tulancingo, Hidalgo: 2,478, Tlaxcala, Tlaxcala: 2,574, Cancun, Quintana Roo: 840; total male: 4,190 (51%). The overall average rate of prevalence of allergic rhinitis among four states including all respondents ages was 15%. With the use of the questionnaire diagnosis of allergic rhinitis for epidemiological studies in the four cities in four different states, we found a prevalence of allergic rhinitis of 15% in ≥13 yearpopulation and 13% in ≤12 year-old children.

Asthma and allergic rhinitis are the two most common chronic disorders in childhood and adolescence. To date, no study has examined the impact of comorbid allergic rhinitis on asthma control in children. To examine the prevalence of allergic rhinitis in children with asthma, and the impact of the disease and its treatment on asthma control. A cross-sectional survey in 203 children with asthma (5-18 years) using validated questionnaires on rhinitis symptoms (stuffy or runny nose outside a cold) and its treatment, and the paediatric Asthma Control Questionnaire (ACQ). Fraction of nitric oxide in exhaled air (FeNO) was measured with a Niox Mino analyser; total and specific IgE levels were assessed by the Immunocap system. 157 children (76.2%) had symptoms of allergic rhinitis but only 88 of these (56.1%) had been diagnosed with the condition by a physician. ACQ scores were worse in children with allergic rhinitis than in those without the condition (p=0.012). An ACQ score ≥ 1.0 (incomplete asthma control) was significantly more likely in children with allergic rhinitis than in those without (OR 2.74, 95% CI 1.28 to 5.91, p=0.0081), also after adjustment for FeNO levels and total serum IgE. After adjustment for nasal corticosteroid therapy, allergic rhinitis was no longer associated with incomplete asthma control (OR 0.72, 95% CI 0.47 to 1.12, p=0.150). Allergic rhinitis is common in children with asthma, and has a major impact on asthma control. The authors hypothesise that recognition and treatment of this condition with nasal corticosteroids may improve asthma control in children, but randomised clinical trials are needed to test this hypothesis.

Cost-benefit analysis of first-generation antihistamines in the treatment of allergic rhinitis.

The majority of individuals with allergic rhinitis in the US take first-generation antihistamines (FGAs). Although FGAs have been proven effective in alleviating allergic rhinitis symptoms, they have been associated with an increased risk of motor vehicle, aviation and occupational injuries and deaths, reduced productivity and impaired learning. The objective of this analysis was to quantify the total costs and benefits of FGA use in the US from the societal perspective. We used a decision-analytic model to quantify the annual societal costs and benefits of treatment with FGAs compared with the hypothetical alternative of no treatment for the population of individuals with allergic rhinitis and taking FGAs in the US in 2001. The benefit associated with FGA use was estimated using the willingness-to-pay framework and projected to the US population using published estimates of the prevalence of allergic rhinitis. The costs of FGA-associated sedation included lost productivity and the direct and indirect cost of unintentional injuries (including motor vehicle, occupational, public and home injuries and fatalities). The incidence of injuries and fatalities associated with FGA use was estimated using the risk of injury attributable to the sedentary effects of FGAs in the allergic rhinitis population. To evaluate uncertainty in the model assumptions, a probabilistic sensitivity analysis was conducted using Bayesian second-order Monte Carlo simulation. Costs and benefits are expressed in 2001 US dollars, using a 3% discount rate. Based on current utilisation, the total societal benefit (95% credible interval) associated with the use of FGAs for the treatment of allergic rhinitis was US 7.7 billion dollars (US 1.3 billion dollars to US 21 billion dollars). The societal cost of purchasing FGAs was only US 697 million dollars. However, the societal cost of FGA-associated sedation was US 11.3 billion dollars (US 2.4 billion dollars to US 50.8 billion dollars). The annual

Bilastine: in allergic rhinitis and urticaria.

PubMed

Carter, Natalie J

2012-06-18

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.

Accumulating evidence is indicating that hormonal factors play a role in new-onset allergic rhinitis and asthma after puberty. To determine whether age at menarche and use of hormonal contraceptives predict new-onset allergic rhinitis and asthma after puberty in young German women. A prospective community-based cohort study followed 1,191 girls 9 to 11 years old to early adulthood (19-24 years old). Self-administrated questionnaires concerning age at menarche, use of hormonal contraceptives, and status and age at onset of physician-diagnosed allergic rhinitis and asthma were collected at 16 to 18 and 19 to 24 years of age. Logistic regression models were used to analyze the incidence of asthma and allergic rhinitis after puberty and pooled estimates were obtained from the final model. Eleven percent of girls developed allergic rhinitis after menarche and 3% reported new-onset asthma. Late menarche (>13 years of age) was statistically significantly inversely related to allergic rhinitis (adjusted odds ratio [OR] 0.32, 95% confidence interval [CI] 0.14-0.74) but did not reach the level of statistical significance for asthma (OR 0.32, 95% CI 0.07-1.42). Use of hormonal contraceptives was inversely associated with new-onset allergic rhinitis (OR 0.14, 95% CI 0.08-0.23) and asthma (OR 0.27, 95% CI 0.12-0.58) after puberty. This study shows that girls with late onset of menarche are less likely to develop allergic rhinitis after puberty compared with those who have menarche at an average age. These findings also suggest that, in addition to endogenous hormones, hormonal contraceptives play a role and might protect young women from allergies and asthma.

[Allergic Rhinitis and its Impact on Asthma (ARIA) in Latin America].

PubMed

Baena-Cagnani, Carlos E

2002-01-01

Allergic rhinitis is the commonest chronic respiratory disorder in children and young adults having an important impact for those suffering this condition, as well as for the public health. Allergic rhinitis is frequently associated to other co-morbidities, particularly asthma and conjunctivitis but, also, sinusitis and otitis media. Most of patients suffering rhinitis are cared by GPs and pediatricians and there are evidences that allergic rhinitis is undertreated, particularly the moderate/severe persistent forms. Clinical guidelines have become an important tool providing recommendations for diagnosis and treatment of different medical conditions. They help the process of decision making for GPs and pediatricians, and many of them, contain an update on basic science and epidemiology. In respiratory medicine, guidelines on asthma and rhinitis are available; however, they do not look at the patients globally and focus the disorder on an organ-specific basis without recommendations on co-morbidities. ARIA, Allergic rhinitis and its impact on asthma, has not been developed only to update specialists in allergy/immunology, otorhinolaryngology and neumology on rhinitis and its comorbidities but, also, to provide recommendations for non-specialists. A new classification and severity of allergic rhinitis is proposed replacing the classic perennial and seasonal forms for persistent and intermittent, mild to moderate/severe. ARIA is an initiative in collaboration with the World Health Organization and the master document has been endorsed by many national and international scientific societies and organizations. ARIA is an evidence-based document also stressing on pediatric aspects and providing recommendations for low-income countries.

Fluctuating olfactory sensitivity and distorted odor perception in allergic rhinitis.

To characterize the relationship between allergic rhinitis, the severity and duration of nasal disease, olfactory function, and self-reported olfactory symptoms, including fluctuations or distortions in odor perception. Assessment of olfactory function and symptoms of 90 patients with allergic rhinitis. A clinic of a university teaching hospital and research facility. Sixty patients who presented to the Taste and Smell Clinic who had positive allergy test results and 30 patients who presented to the Allergy-Immunology Clinic. The Taste and Smell Clinic patients were grouped by nasal-sinus disease status (30 without chronic rhinosinusitis or nasal polyps, 14 with chronic rhinosinusitis but without polyps, and 16 with nasal polyps). Subjective olfactory symptom questionnaire and objective olfactory function tests. The Allergy-Immunology Clinic patients were diagnosed as being normosmic and the Taste and Smell Clinic patients as being hyposmic or anosmic with olfactory loss that increased significantly with nasal-sinus disease severity. Comparisons with normative data confirm that olfactory scores observed in all groups were significantly lower than expected because of the aging process alone. The self-reported duration of olfactory loss increased significantly with nasal-sinus disease severity. The Taste and Smell Clinic patients without chronic rhinosinusitis or nasal polyps reported the greatest incidence of olfactory distortions and olfactory loss associated with upper respiratory tract infections. There appears to be a continuum of duration and severity of olfactory loss in allergic rhinitis that parallels increasing severity of nasal-sinus disease. As a result of the increased frequency of respiratory infection associated with allergic rhinitis, these patients are at risk for damage to the olfactory epithelium.

It has been hypothesized that isoflavones reduce the risk of many chronic diseases, but there are no data on the effects of dietary soy and isoflavone consumption on allergic disorders. This cross-sectional study examined the relationship between dietary soy products and isoflavone intake and the prevalence of allergic rhinitis. Study subjects were 1002 Japanese pregnant women. Allergic rhinitis (including cedar pollinosis) was defined as present if subjects had received drug treatment at some point during the previous 12 months. Adjustment was made for age; gestation; parity; cigarette smoking; passive smoking at home and at work; indoor domestic pets; family history of asthma, atopic eczema, and allergic rhinitis; family income; education; mite allergen level in house dust; changes in diet in the previous month; season when data were collected; and body mass index. Compared with dietary intake of total soy product, soy protein, daidzein, and genistein in the first quartile, consumption of these substances in the fourth quartile was independently associated with a reduced prevalence of allergic rhinitis, although no significant dose-response relationships were observed. A clear inverse linear trend for miso intake across quartiles was found, whereas the adjusted odds ratio for comparison of the highest with the lowest quartile was not statistically significant. Consumption of tofu, tofu products, fermented soybeans, boiled soybeans, and miso soup was not related to the prevalence of allergic rhinitis. A high intake of soy and isoflavones may be associated with a reduced prevalence of allergic rhinitis.

Homeopathy for allergic rhinitis: protocol for a systematic review

2014-01-01

Background Allergic rhinitis is a global health problem that is often treated with homeopathy. The objective of this review will be to evaluate the effectiveness of homeopathic treatment of allergic rhinitis. Methods/Design The authors will conduct a systematic review. We will search Medline, CENTRAL, CINAHL, EMBASE, AMED, CAM-Quest, Google Scholar and reference lists of identified studies up to December 2013. The review will include randomized controlled trials that evaluate homeopathic treatment of allergic rhinitis. Studies with participants of all ages, with acute or chronic comorbidities will be included. Patients with immunodeficiency will not be included. The diagnosis will be based on the published guidelines of diagnosis and classification. Studies of all homeopathy modalities (clinical, complex and classical homeopathy, and isopathy) will be included. We will include trials with both active controls (conventional therapy, standard care) and placebo controls. The primary outcomes are: an improvement of global symptoms recorded in validated daily or weekly diaries and any scores from validated visual analogue scales; the total Quality of Life Score (such as the Juniper RQLQ);individual symptoms scores which include any appropriate measures of nasal obstruction, runny nose, sneezing, itching, and eye symptoms; and number of days requiring medication.

Three cases of allergic rhinitis from a vegetable gum, guar gum, have been detected. Two subjects were exposed to fine guar gum powder (Emco Gum 563, Meyhall Chemical AG, Switzerland), an insulator in rubber cables, when opening cables in a power cable laboratory. After 1-2 years' exposure the patients developed rhinitis. Scratch-chamber tests, nasal provocation tests, nasal eosinophilia and a RAST test proved their allergy. A third subject developed allergic rhinitis from another guar gum product (Meyproid 5306, Meyhall Chemical AG) after 2 years' exposure in a paper factory. A positive skin test and nasal provocation test confirmed the diagnosis. A fourth case of possible allergy to guar gum after exposure to Meyproid 5306 in a paper factory is also presented. No final diagnosis was reached in this case (in 1974). The present subjects, only one of whom was atopic, developed allergy within 2 years, although their exposure to guar gum was not especially heavy. Therefore, when handling guar, adequate ventilation facilities should be provided and protective clothing, including a respiratory mask, should be worn.

The use of Apps running on smartphones and tablets profoundly affects medicine. The MASK-rhinitis (MACVIA-ARIA Sentinel NetworK for allergic rhinitis) App (Allergy Diary) assesses allergic rhinitis symptoms, disease control and impact on patients' lives. It is freely available in 20 countries (iOS and Android platforms). To assess in a pilot study whether (i) Allergy Diary users were able to properly provide baseline characteristics (ii) simple phenotypic characteristics based upon data captured by the Allergy Diary could be identified and (iii) information gathered by this study could suggest novel research questions. The Allergy Diary users were classified into six groups according to the baseline data that they entered into the App: (i) asymptomatic; (ii) nasal symptoms excluding rhinorrhea; (iii) rhinorrhea; (iv) rhinorrhea plus 1-2 nasal/ocular symptoms; (v) rhinorrhea plus ≥3 nasal/ocular symptoms; and (vi) rhinorrhea plus all nasal/ocular symptoms. By 1 June 2016, 3260 users had registered with the Allergy Diary and 2710 had completed the baseline questionnaire. Troublesome symptoms were found mainly in the users with the most symptoms. Around 50% of users with troublesome rhinitis and/or ocular symptoms suffered work impairment. Sleep was impaired by troublesome symptoms and nasal obstruction. This is the first App (iOS and Android) to have tested for allergic rhinitis and conjunctivitis. A simple questionnaire administered by cell phones enables the identification of phenotypic differences between a priori defined rhinitis groups. The results suggest novel concepts and research questions in allergic rhinitis that may not be identified using classical methods. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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.

Mobile technology has been used to appraise allergic rhinitis control, but more data are needed. To better assess the importance of mobile technologies in rhinitis control, the ARIA (Allergic Rhinitis and its Impact on Asthma) score ranging from 0 to 4 of the Allergy Diary was compared with EQ-5D (EuroQuol) and WPAI-AS (Work Productivity and Activity Impairment in allergy) in 1288 users in 18 countries. This study showed that quality-of-life data (EQ-5D visual analogue scale and WPA-IS Question 9) are similar in users without rhinitis and in those with mild rhinitis (scores 0-2). Users with a score of 3 or 4 had a significant impairment in quality-of-life questionnaires. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

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.

The incidence of asthma and allergic rhinitis (AR) is significantly increased, especially in younger children. Current treatment for children with asthma and allergic rhinitis include allergen avoidance, standard pharmacotherapy, and immunotherapy. Since standard pharmacotherapy is prescribed for symptoms, immunotherapy at present plays an important role in the treatment of allergic diseases. This article presents insights into the up-to-date understanding of immunotherapy in the treatment of children with allergic rhinitis and asthma. PubMed articles published from 1990 to 2014 were reviewed using the MeSH terms "asthma", "allergic rhinitis", "children", and "immune therapy". Additional articles were identified by hand searching of the references in the initial search. Numerous studies have shown that sublingual application of allergen specific immunotherapy (SLIT) is an adequate, safe and efficient substitution to subcutaneous route of allergens administration (SCIT) in the treatment of IgE-mediated respiratory tract allergies in children. According to the literature, better clinical efficacy is connected with the duration of treatment and mono sensitized patients. At least 3 years of treatment and stable asthma before the immunotherapy are positive predictors of good clinical efficacy and tolerability of SLIT. SLIT reduces the symptoms of allergic diseases and the use of medicaments, and improves the quality of life of children with the diseases.

Allergic rhinitis (AR) is especially prevalent among the population of large cities. Immunologically, the airway epithelium is a region where the population of allergen-presenting cells concentrates. These cells actively express a group of receptors of the innate immune system. A specific cytokine profile is its representation. The study was aimed at evaluating the cytokine profile in patients with seasonal and perennial allergic rhinitis. The cytokine profile of nasal secretion and blood serum of 44 patients with AR was studied. 24 of them had seasonal allergic rhinitis (SAR), and 20 patients suffered from perennial allergic rhinitis (PAR). The patients' age ranged from 4 to 60 years. It was determined in our study that the activation of the GM-CSF production retained in patients with PAR sensitized to mite allergen components ( Dermatophagoides pteronyssinus ). There was a higher production profile of TNF- α and TSLP in nasal secretion in the patients with perennial allergic rhinitis and additional high sensitization to SEs. Sensitization to mold fungal allergen components significantly increases in patients with seasonal allergic rhinitis. They demonstrated high level of sensitization to the Aspergillus fumigatus component m3. Thus, along with other clinical trials, the study performed would clarify some aspects of molecular pathogenesis of human allergic rhinitis.

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.

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

Allergic rhinitis and allergy are complex conditions, in which both genetic and environmental factors contribute to the pathogenesis. Genome-wide association studies (GWASs) employing common single-nucleotide polymorphisms have accelerated the search for novel and interesting genes, and also confirmed the role of some previously described genes which may be involved in the cause of allergic rhinitis and allergy. The aim of this review is to provide an overview of the genetic basis of allergic rhinitis and the associated allergic phenotypes, with particular focus on GWASs. The last decade has been marked by the publication of more than 20 GWASs of allergic rhinitis and the associated allergic phenotypes. Allergic diseases and traits have been shown to share a large number of genetic susceptibility loci, of which IL33/IL1RL1, IL-13-RAD50 and C11orf30/LRRC32 appear to be important for more than two allergic phenotypes. GWASs have further reflected the genetic heterogeneity underlying allergic phenotypes. Large-scale genome-wide association strategies are underway to discover new susceptibility variants for allergic rhinitis and allergic phenotypes. Characterization of the underlying genetics provides us with an insight into the potential targets for future studies and the corresponding interventions.

Allergic rhinitis (AR) is a relevant risk factor for the onset of asthma, and a close association exists between the nose and the bronchi. Recently, it has been evidenced that the duration of AR and mite allergy represent high risks for spirometric impairment in allergic adults. To evaluate a group of AR children, without bronchial symptoms, to investigate spirometric impairments. Two hundred children with moderate-severe AR were consecutively evaluated. Clinical examination, skin prick test, and spirometry were performed in all children. Thirty-one percent of the children had forced expiratory flow at 25% and 75% of the pulmonary volume (FEF25-75%)<80% of the predicted values and 11% had both forced expiratory volume in 1 s and FEF25-75%<80% of the predicted values. Rhinitis duration and sensitization to house dust mites were significantly associated with impaired values of these spirometric parameters. This study highlights the close link between the upper and the lower airways and the role of some risk factors, such as long duration and mite sensitization, as early prognostic markers of bronchial involvement in children with AR and perceiving nasal symptoms alone.

We aim to describe the data collected from India during phase 3 of the International study of asthma and allergy in childhood (ISAAC) study. Prevalence, severity, and population characteristics associated with rhinitis, rhinoconjunctivitis, and eczema were assessed. Children from two age groups (6-7 and 13-14 years) were included in the study as per the ISAAC protocol. The symptoms of allergy and associated features were assessed using a questionnaire. The prevalence of allergic rhinitis among the 6-7 years age group was 11.3%, while it was 24.4% in the 13-14 years age group. The prevalence of allergic rhinoconjunctivitis was 3.9% in the 6-7 years age group and 10.9% in the 13-14 years age group. The prevalence of eczema was 2.8% in the 6-7 years age group and 3.7% in the 13-14 years age group. The passage of trucks near home, parental smoking, use of paracetamol, use of antibiotics, cooking with firewood, and television watching were associated with allergic rhinitis, rhinoconjunctivitis, and eczema. Maternal smoking was the strongest of all the associated features for allergic rhinitis, rhinoconjunctivitis, and eczema, especially in the 6-7 years age group (odds ratio: 1.9, 95% CI: 1.5-2.4; odds ratio: 2.9, 95% CI, 2.2-3.9; and odds ratio: 3.5, 95% CI: 2.6-4.8, respectively). Allergic conditions like allergic rhinitis, rhinoconjunctivitis, and eczema are prevalent among Indian children and are associated with environmental tobacco smoke, paracetamol use, antibiotic use, television watching, and outdoor and indoor air pollution. © 2016 John Wiley & Sons Ltd.

Despite links between maternal and child health status, evidence on the association between gum infection in pregnant mothers and childhood allergies is scarce. We aim to evaluate the risk of developing allergy in children born to periodontal mothers in a nationwide study. We conducted a 9-year population-based, retrospective cohort study using Taiwan's National Health Insurance database. A study cohort of 42,217 newborns born to mothers with periodontal disease during pregnancy was identified in 2001 and matched with 42,334 babies born to mothers without any infection (control) by mother's age at delivery and baby sex. With a follow-up period from 2001 to 2010, we observed the incidence of allergic rhinitis (AR), allergic conjunctivitis (AC), and eczema in these children. Cox proportional hazards regression models were performed with premature deaths as competing risk for the estimation of allergic disease risks. Nine-year cumulative incidences were the highest among children born to periodontal mothers; they reached 46.8%, 24.2%, and 40.4% (vs. 39.5%, 18.3% and 34.8% in control) for AR, AC, and eczema, respectively. Our results showed moderately increased risks for the allergies in children born to periodontal mothers relative to their matched non-inflammatory control (adjusted HRs: 1.17, 95% CI: 1.15-1.20; 1.27, 1.24-1.31; 1.14, 1.12-1.17, respectively). Because the impact of food consumption and living environment cannot be considered using insurance data, we attempted to control it by adjusting for parental income and mother's residential area. Overall cumulative incidence and risks of children born to periodontal mothers for AR, AC, and eczema are significantly higher than those born to non-inflammatory mothers. Gum infection in women during pregnancy is an independent risk factor for allergic diseases in children, thus its intergenerational consequences should be considered in gestational care.

The prevalence of allergic rhinitis and the social burden related to the management of allergic rhinitis have persistently increased. There are many studies investigating the association between the allergic diseases of children and the stress of their parent. However, the relationship between parenting stress and the incidence of allergic rhinitis among children requires further investigation. We aimed to investigate the significance of parenting stress for mothers with children treated for allergic rhinitis. The mothers of 250 children in the second and third grade of elementary school were involved in this study. The Parenting Stress Index-Short Form (PSI-SF) was used to measure parenting stress. Additionally, the monthly household income, treatment history for allergic diseases (atopic dermatitis, asthma, and allergic rhinitis) during the past 12 months, and maternal education status were investigated using the questionnaire. Parenting stress index score was significantly higher among the mothers of children treated for allergic rhinitis (76.41 ± 9.35) compared with the parents of children without treatment history for allergic rhinitis (70.06 ± 13.74). Nonetheless, there were no significant differences between the cases of children with atopic dermatitis and those with asthma. We analyzed the association between allergic rhinitis and parenting stress adjusted for the monthly household income, and maternal education status, and showed that a treatment history of allergic rhinitis was significantly associated with parenting stress (coefficient 7.477, 95% interval 1.703-13.252; p = 0.011). Treatment of the children for allergic rhinitis significantly affects the parenting stress of their mother. We recommend that mothers with children with allergic rhinitis should receive appropriate counseling about parenting stress. Copyright © 2017 Elsevier B.V. All rights reserved.

Orthodontists frequently treat children with mouth breathing. The purpose of the present study was to examine dental positions, skeletal effects and the pharyngeal airway space of children with chronic allergic rhinitis, when compared with a control group exhibiting a normal breathing pattern. Seventy Caucasian children from Santa Maria University Hospital - North Lisbon Hospital Center were evaluated, between September 2009 and February 2013. The study group comprised of 35 children with chronic allergic rhinitis, both genders, aged 5 - 14, with positive reaction to allergens, mouth breathing and malocclusion. The control group was composed of 35 children, both genders, displaying normal nasal breathing and malocclusion, who resorted to the orthodontic department. Measures of Ricketts, Steiner and McNamara's analysis were used and the t- Student test was applied to the data obtained. Statistically significant differences were observed between the oral and nasal breathers, respectively: lower facial height (49.1/45.9 mm), Frankfurt â mandibular plane angle (30.1/26.9º) and Sela-Nasion - oclusal plane angle (17.3/15º), maxillary length (78.4/82.4 mm), mandibular length (102.4/107 mm), overbite (0.8/3.1mm) and overjet (4/4.7 mm). Comparison between the allergic rhinitis and control group showed that there is an increased lower facial height, larger Frankfurt â mandibular plane angle and Sela-Nasion oclusal plane angle in children with chronic allergic rhinitis. This group also had a shorter maxillary and mandibular length, less overbite and decreased upper airway space. Children with allergic rhinitis and mouth breathing have longer faces, shorter maxillas and mandibles and a narrowed pharyngeal airway space. No statistical differences between the groups in sagital relationships or in dental inclinations were found.

Mounting evidence suggests that exposure to ambient air pollution is associated with the development of childhood allergic diseases, but the effect of prenatal exposure to air pollution on the risk of childhood asthma and allergy is unclear. We evaluated the association between maternal exposure to outdoor air pollution during different trimesters of pregnancy and incidence of asthma, allergic rhinitis, and eczema in 2598 preschool children aged 3-6 years in China. Children's lifetime incidence of allergic diseases was obtained using questionnaire. Individual exposure to outdoor air pollutants during trimesters of pregnancy was estimated by an inverse distance weighted (IDW) method based on the measured concentrations at monitoring stations. We used multiple logistic regression method to estimate the odds ratio (OR) of asthma, allergic rhinitis, and eczema for per interquartile range (IQR) increase in the exposure to air pollutant in each trimester, which was adjusted for the effect of other air pollutants and its effect in other trimesters by a multi-pollutant/trimester model. Incidence of asthma (6.8%), allergic rhinitis (7.3%), and eczema (28.6%) in children was associated with maternal exposure to traffic-related pollutant NO2 during entire pregnancy with OR (95% confidence interval [CI]) respectively 1.63 (0.99-2.70), 1.69 (1.03-2.77), and 1.37 (1.04-1.80). After adjustment for other pollutants and trimesters, we found the association was significant only in specific trimester: the first trimester for eczema (1.54, 1.14-2.09), the second trimester for asthma (1.72, 1.02-2.97), and the third trimester for allergic rhinitis (1.77, 1.09-2.89). Sensitivity analysis indicated that the trimester sensitive to the development of allergic diseases was stable. Maternal exposure to traffic-related air pollutant NO2 during pregnancy, especially in specific trimesters, is associated with an increased risk of developing asthma, rhinitis, and eczema in children.

Rhinitis is the most frequent respiratory disease in most countries of the world. It is estimated that 600 million people suffer this condition. Allergic rhinitis is a public health problem at global level. Patients who suffer allergic rhinitis have from mild to annoying nasal symptoms which affect quality of life, cause sleep disorders, scholar and workplace absenteeism, and health expenditure. Rhinitis is frequently associated to co-morbidities such as sinusitis, otitis media, and especially asthma. Rhinitis is under-diagnosed and under-treated worldwide and also in Latin American countries. ARIA is the very first evidence-based guideline for the diagnosis and treatment of rhinitis with focus in its co-morbidities (2001), especially asthma published in 2001. In 2008 an update was published. ARIA recommends an integrative approach for management; including anti-histamines (second generation), intra-nasal corticosteroids, anti-leukotrienes and immunotherapy. It also provides a questionnaire to evaluate asthma and its severity in those patients suffering rhinitis. The prevalence of allergic rhinitis is quite high in Latin American countries and in recent years a great insight on the burden of this condition has been gained.

Study of frequency of allergic rhinitis in selected regions of Poland in cities and countryside. 8913 respondents, from Warszawa, Katowice, Lublin and Zamojszczyzna (countryside), answered a questionnaire based on ECRHS II and ISAAC. The respondents were drawn from PESEL ID numbers. They were divided into three groups: 6-7 years, 13-14 and 20-44 years, both sexes. 21-23% adults living in the city and 12% living in the countryside confirmed some type of sensitization, including allergic catarrh. In children the same symptoms are more frequent and reported in 23-27% of those living in city and 17% of those living in the countryside. Sneezing, running or obstructed nose not related to cold, fever or flu were reported by 22% of the adults living in Zamojszczyzna and 33-42% of those living in the cities. The symptoms are reported in 20% children living in the countryside and 29-39% of those living in the cities. All of results are statistical significant. Study of frequency of allergic rhinitis in selected regions of Poland shows that results are similar with analysis on the world. Connection between urban development and occurrence of allergic rhinitis was confirmed. Allergic rhinitis is more frequently in group of people living in cities than people living on countryside. Probably allergic rhinitis is not integrally examined in adults group.

Objective : The aim of this study was to identify diseases linked with the pesticide sprayer occupation and explore possible associations with exposure history data. Methods : Α cross sectional study was conducted among pesticide sprayers ( n = 80) and the general population ( n = 90) in Thessaly (Greece). Medical history, demographic characteristics and detailed exposure history were recorded by conducting personal interviews. Lifetime exposure indicators were calculated for several pesticide chemical subclasses. Moreover, organophosphate metabolite levels were quantified in urine samples of all participants by using gas chromatography -mass spectrometry (GC-MS). Multinomial analysis was used to determine associations between occupational pesticide exposure and diseases or disorders. Results : In the pesticide sprayers group, significantly higher frequencies for rheumatoid arthritis (RA) and allergic rhinitis were observed compared with the control group ( p = 0.002 and p = 0.024 respectively). Within the pesticide sprayers group, high lifetime pesticide exposure was associated with increased risk for reporting RA (OR: 43.07 95% CI: 3.09-600.67) and allergic rhinitis (OR: 9.72 95% CI: 2.31-40.89), compared with low pesticide exposure. Exposure to organophsphate, guanidine and quinone pesticides were associated with RA while organophosphates, pyrethroids and paraquat were associated with allergic rhinitis. Despite the higher levels of certain pesticide metabolites observed among participants with rheumatoid arthritis, the differences were not statistically significant. One metabolite (diethylthiophosphate) was found to be significantly increased in allergic rhinitis cases ( p = 0.037). Conclusion s : The results from the current study suggest a possible association of occupational pesticide exposure with RA and allergic rhinitis that should be further investigated.

Allergic Rhinitis is a universal common disease, especially in populated cities and urban areas. Diagnosis and treatment of Allergic Rhinitis will improve the quality of life of allergic patients. Though skin tests remain the gold standard test for diagnosis of allergic disorders, clinical experts are required for accurate interpretation of test outcomes. This work presents a clinical decision support system (CDSS) to assist junior clinicians in the diagnosis of Allergic Rhinitis. Intradermal Skin tests were performed on patients who had plausible allergic symptoms. Based on patient׳s history, 40 clinically relevant allergens were tested. 872 patients who had allergic symptoms were considered for this study. The rule based classification approach and the clinical test results were used to develop and validate the CDSS. Clinical relevance of the CDSS was compared with the Score for Allergic Rhinitis (SFAR). Tests were conducted for junior clinicians to assess their diagnostic capability in the absence of an expert. The class based Association rule generation approach provides a concise set of rules that is further validated by clinical experts. The interpretations of the experts are considered as the gold standard. The CDSS diagnoses the presence or absence of rhinitis with an accuracy of 88.31%. The allergy specialist and the junior clinicians prefer the rule based approach for its comprehendible knowledge model. The Clinical Decision Support Systems with rule based classification approach assists junior doctors and clinicians in the diagnosis of Allergic Rhinitis to make reliable decisions based on the reports of intradermal skin tests.

Objectives To investigate the effect of rhinophototherapy with medical therapy on quality of life in persistent allergic rhinitis. Methods A prospective, randomized study was being performed between December 2009 and March 2010. The study included 65 patients with persistent allergic rhinitis. The diagnosis was confirmed with positive skin tests. All of the patients had house dust mite allergies. We divided the patients into two groups. First group (n=33) was given topical mometasone furoate 200 mcg/day and levocetirizine 5 mg/day for a month. Rhinophototherapy was applied with the same medical therapy to the second group (n=32), twice a week for three weeks continuously. Rhinophototherapy included visible light, ultraviolet A and ultraviolet B. We evaluated patients before the treatment, at the first month and at the third month after treatment with rhinoconjunctivitis quality of life questionnaire, nasal symptom scores and visual analogue scale (VAS) scores. Results Improvements of all variables of the quality of life questionnaire, nasal symptom scores and VAS were statistically significant in the second group both on the first and the third months when compared with the first group. Conclusion Allergic rhinitis is a social problem and impairs quality of life. Rhinophototherapy with medical therapy improves the quality of life in allergic rhinitis. PMID:23799163

Allergic rhinitis is a very common disease that causes high economic costs. Furthermore inadequate treatment can lead to bronchial asthma. Against this background, drugs for the treatment of allergic rhinitis should be evaluated from a comprehensive medical-economic perspective. The new combination of an antihistamine and a corticosteroid, introduced in the market in 2013, emerges as useful pharmaceutical alternative, both with regard to the medical outcome parameters as well as cost-effectiveness.

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 frequency of allergic diseases such as allergic rhinitis is considerable in general population. Insect aeroallergens are important allergens which can induce airway inflammation. The aim of this study was to determine the prevalence of sensitization to insect aeroallergens in allergic rhinitis patients in Yazd as a desert city in Iran.A cross-sectional study was undertaken on 95 allergic rhinitis patients who were referred to allergy clinic of Yazd city. Skin prick tests (SPT) by standard extracts of three insect aeroallergens including Mosquito, Corn moth, Cockroach and two species of mites as common aeroallergens in allergic rhinitis (Dermatophagoid Farina, Dermatophagoid Peteronysinus) were done.SPT results showed that the most common insect aeroallergens were: mosquito (32.6%) followed by corn moth (26.3%) and cockroach (13.7%).The prevalence of SPT positive response to Dermatophagoid Peteronysinus, Dermatophagoid Farina were 8.4% and 7.4%, respectively. These results demonstrated that sensitization to insect aeroallergens was significantly more common compared to mites in patients with allergic rhinitis in Yazd city, a city surrounded by deserts. High prevalence of skin reactivity to mosquito and corn moth as insect aeroallergens in Yazd city with hot and dry climate in contrast to humid regions such as north of Iran, where mites are more frequent, indicates differences in the prevalence of aeroallergen reactivity in various areas with different climates. Our study could highlight the importance of insect aeroallergens for clinicians for better diagnosis and management of patients with allergic rhinitis.

In this study, we assessed the effect of endonasal phototherapy on quality of life, nasal obstruction and the other symptoms in allergic rhinitis with visual analog scale (VAS), sinonasal outcome test-20 (SNOT-20), and acoustic rhinometry. Twenty-four patients (6 males, 18 females; mean age 41.3±13.0 years; range 20 to 60 years) suffering allergic rhinitis refractory to anti allergic drugs for at least two years were enrolled in the study. Each patient underwent a total of six sessions of endonasal phototherapy with Rhinolight (Rhinolight Ltd, Szeged, Hungary) performed three times a week for two weeks. During course of the investigation, additional therapy was not applied to any of the patients. Before and one month after treatment, patients completed visual analog scale and SNOT-20 forms and nasal obstruction was evaluated with acoustic rhinometry. After the treatment, the mean VAS score and the mean total SNOT-20 score were found lower than the results before the therapy (p=0.0001, p=0.0001). A significant decrease was found in the scores of sneezing, nasal discharge, postnasal drainage, coughing after treatment (p=0.0001). During objective evaluation of nasal obstruction with acoustic rhinometry, no statistically significant difference was found between pre- and post-treatment findings. Endonasal phototherapy is an effective modality in the treatment of symptomatology in allergic rhinitis patients refractory to antiallergic drugs. It is detected that endonasal phototherapy has positive effects on the quality of life. However, no effect on nasal obstruction was found with acoustic rhinometry which is an objective method.

Plasminogen activator inhibitor-1 (PAI-1) is a glycoprotein which has a role in tissue remodelling after inflammatory processes. The objective is to investigate the frequency of PAI-1 gene polymorphism (4G/5G) in patients with a lung ventilation dysfunction in asthma and allergic rhinitis. Genomic DNA was isolated and genotypes of polymorphism of PAI-1 4G/5G and ABO were determined using the methods of RT-PCR and PCR-SSP. Study group includes 145 adult patients diagnosed with chronic asthma, with all clinically relevant parameters and the laboratory markers of pO 2 , IgE and eosinophils in sputum and nasal swab. In the processing of data, appropriate statistical tests (Kolmogorov-Smirnov test, median, interquartile ranges, χ 2 and Mann-Whitney U tests) were used. Patients with symptoms of allergic rhinitis were significantly younger and had an almost four time higher levels of IgE (P = 0.001), higher pO 2 (P = 0.002) and PEF (P = 0.036), compared to those who do not have these symptoms. Genotype PAI 4G/4G is significantly more common in patients with allergic rhinitis (28.1% vs. 16.1%; P = 0.017) compared to the genotype 5G/5G. Carriers of the genotype 4G/5G also have a borderline statistical significance. There were no statistically significant difference in the incidence of allergic rhinitis in the carriers of any ABO genotypes. The frequency of PAI genotype 4G/4G is significantly more common in patients with allergic rhinitis. The results suggest that the carriers of at least one 4G allele are at a higher risk for developing symptoms of allergic rhinitis in asthma.

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.

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 group had more school

Allergic rhinitis is the most common form of non-infectious rhinitis, affecting 500 million people worldwide, with one-fifth of those affected living in the Indian subcontinent. The skin prick test is the most valuable test for detecting offending allergens, and can be helpful for patient education, allergen avoidance and immunotherapy planning. The skin prick test was performed with 49 allergens in 486 patients who presented with symptoms of allergic rhinitis, and the allergen profile was studied. Of the 486 allergic rhinitis patients, 335 (68.93 per cent) showed allergen positivity to the skin prick test. Dust mite was the most common allergen, with positive results in 44.65 per cent of cases. The most common offending allergen in our study was the dust mite. Identification of specific allergens for a particular geographical area aids patient education and enables allergen-specific immunotherapy.

To investigate the prevalence of allergic rhinitis among elementary and middle school students and examine its impact on their quality of life. Stratified sampling and cluster sampling surveys were performed among 10-17-year-old students in Changsha city from June 2011 to April 2012. In the stratified sampling survey, the self-reported allergic rhinitis rate was 42.5 per cent. Further examination demonstrated that the average prevalence of allergic rhinitis was 19.4 per cent. The cluster sampling survey demonstrated that 214 of 814 students appeared to be atopic (26.3 per cent). The prevalence of allergic rhinitis and asthma was 17.2 and 2.1 per cent, respectively. In total, 71 atopic individuals (8.7 per cent) were without any symptoms of allergic disease. Further analysis showed that allergic rhinitis influenced the students' sleep, emotions and memory (p < 0.001). The prevalence of allergic rhinitis was 15.8 -19.4 per cent, showing an increase with age. Allergic rhinitis affected students' sleep, emotions and memory.

Purpose Despite links between maternal and child health status, evidence on the association between gum infection in pregnant mothers and childhood allergies is scarce. We aim to evaluate the risk of developing allergy in children born to periodontal mothers in a nationwide study. Methods We conducted a 9-year population-based, retrospective cohort study using Taiwan’s National Health Insurance database. A study cohort of 42,217 newborns born to mothers with periodontal disease during pregnancy was identified in 2001 and matched with 42,334 babies born to mothers without any infection (control) by mother’s age at delivery and baby sex. With a follow-up period from 2001 to 2010, we observed the incidence of allergic rhinitis (AR), allergic conjunctivitis (AC), and eczema in these children. Cox proportional hazards regression models were performed with premature deaths as competing risk for the estimation of allergic disease risks. Results Nine-year cumulative incidences were the highest among children born to periodontal mothers; they reached 46.8%, 24.2%, and 40.4% (vs. 39.5%, 18.3% and 34.8% in control) for AR, AC, and eczema, respectively. Our results showed moderately increased risks for the allergies in children born to periodontal mothers relative to their matched non-inflammatory control (adjusted HRs: 1.17, 95% CI: 1.15–1.20; 1.27, 1.24–1.31; 1.14, 1.12–1.17, respectively). Because the impact of food consumption and living environment cannot be considered using insurance data, we attempted to control it by adjusting for parental income and mother’s residential area. Conclusions Overall cumulative incidence and risks of children born to periodontal mothers for AR, AC, and eczema are significantly higher than those born to non-inflammatory mothers. Gum infection in women during pregnancy is an independent risk factor for allergic diseases in children, thus its intergenerational consequences should be considered in gestational care.

In our experience Allergic Rhinitis (AR) patients suffer from voice problems more than health subjects. To investigate the acoustic analysis of voice, stroscopic findings of larynx and Voice Handicap Index scores in allergic rhinitis patients compared with healthy controls. Case-control study. 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. 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. Our findings suggest that the presence of allergies could have effects on laryngeal dysfunction and voice-related quality of life.

Little is known about the relation between allergic rhinitis severity and airborne pollen in combination with air pollutants. To model the risk of suffering from severe seasonal allergic rhinitis (SAR) as a function of both pollen count and air pollution levels in a large nationwide sample of patients whose SAR was diagnosed by a physician and confirmed by skin prick test positivity or specific immunolglobulin E to common aeroallergens. The severity of SAR symptoms was estimated with the Symptomatic Global Score (SGS) among 36,397 patients suffering from an untreated and uncomplicated SAR between May and August 2004 in metropolitan France. Patients who had an SGS in the upper third quartile were classified as suffering from severe SAR. A multilevel model relating SAR severity, pollen and air pollution was used to take into account the hierarchical data structure. 18.9% of the 17,567 urban patients retained for the analysis suffered from severe rhinitis. At the Lag0 (day of the visit), a rise of 60 grass pollen grains/m(3) increased the risk of suffering from a severe SAR form by 8% in the multileveled model after adjusting for potential confounders and air pollution levels. Results were also confirmed in the subsample of individuals with documented sensitization to grass pollen. Grass pollen count aggravated SAR in terms of symptoms in our nationwide sample. These findings confirm the need for proper treatment and preventive measures in SAR patients sensitized to grass pollen. Copyright © 2012 S. Karger AG, Basel.

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.

Allergic rhinitis is a frequent presenting problem in primary care in the UK, and has increased in prevalence over the last 30 years. When symptomatic, patients report significant reduction in their quality of life and impairment in school and work performance. Achieving adequate symptom control is pivotal to successful allergic rhinitis management, and relies mostly on pharmacotherapy. While it is recognised that most mild-moderate allergic rhinitis symptoms can be managed successfully in primary care, important gaps in general practitioner training in relation to allergic rhinitis have been identified. With the availability of new effective combination therapies, such as the novel intranasal formulation of azelastine hydrochloride and fluticasone propionate in a single device (Dymista®; Meda), the majority of allergic rhinitis symptoms can be treated in the primary care setting. The primary objective of this consensus statement is to improve diagnosis and treatment of allergic rhinitis in primary care, and offer guidance on appropriate referral of difficult-to-treat patients into secondary care. The guidance provided herein outlines a sequential treatment pathway for allergic rhinitis in primary care that incorporates a considered approach to improve the management of allergic rhinitis symptoms and improve compliance and patient satisfaction with therapy. Adherence with this care pathway has the potential to limit the cost of providing effective allergic rhinitis management in the UK by avoiding unnecessary treatments and investigations, and avoiding the need for costly referrals to secondary care in the majority of allergic rhinitis cases. The fundamentals presented in this consensus article should apply in most health-care settings.

Allergic and non-allergic rhinitis cause a lot of symptoms in everyday life. To decrease the burden more information of the preventable risk factors is needed. We assessed prevalence and risk factors for chronic nasal symptoms, exploring the effects of smoking, environmental tobacco smoke, exposure to occupational irritants, and their combinations. In 2016, a postal survey was conducted among a random population sample of 8000 adults in Helsinki, Finland with a 50.5% response rate. Smoking was associated with a significant increase in occurrence of chronic rhinitis (longstanding nasal congestion or runny nose), but not with self-reported or physician diagnosed allergic rhinitis. The highest prevalence estimates of nasal symptoms, 55.1% for chronic rhinitis, 49.1% for nasal congestion, and 40.7% for runny nose, were found among smokers with occupational exposure to gases, fumes or dusts.Besides active smoking, also exposure to environmental tobacco smoke combined with occupational exposure increased the risk of nasal symptoms. Smoking, environmental tobacco smoke, and occupational irritants are significant risk factors for nasal symptoms with an additive pattern. The findings suggest that these factors should be systematically inquired in patients with nasal symptoms for appropriate preventive measures. (192 words).

Formulation considerations of intranasal corticosteroids for the treatment of allergic rhinitis.

PubMed

Meltzer, Eli O

2007-01-01

To examine how various aspects of an intranasal corticosteroid (INS) formulation may influence the efficacy, tolerability, and patient preference and adherence to INS therapy. A PubMed search of the literature was conducted for studies on allergic rhinitis published between January 1977 and January 2006 using the keywords intranasal corticosteroid, preservatives, benzalkonium chloride, and tonicity. Prospective studies, retrospective studies, and case reports were selected for inclusion in this review. Currently available INSs are effective first-line treatments for allergic rhinitis. Differences in patient preference for a particular INS are largely attributable to sensory attributes of the nasal spray, which arise from characteristics of the formulation. Additives and preservatives can cause tolerability issues by irritating the mucosal membranes and causing nasal drying, or they can confer an unpleasant odor or taste to an INS formulation. The relative osmotic pressure, or tonicity, of an INS can modulate nasal absorption and retention, thereby potentially influencing the clinical efficacy. Characteristics such as delivery device and spray volume can affect a patient's perception and experience with a particular INS. Newer INSs, such as ciclesonide, are in development for the treatment of allergic rhinitis, and consideration of the formulation characteristics of these agents is an important part of the development process. INSs are an effective treatment option for patients with allergic rhinitis; however, there is room for formulation improvement. Optimization of formulation may increase the efficacy, tolerability, and patient preference and adherence to INSs.

To determine the distribution of allergens in patients with allergic rhinitis during from 2008 to 2015 in Changzhou area. Allergy Screen method was used to detect the specifical-allergen IgE levels of 1172 patients with allergic rhinitis. Among the patients, the distribution of all allergens was analyzed. The positive rate was compared with age, gender, season and so on. The most common allergens in allergic rhinitis patients in Changzhou were dust mite, fungus, house dust, milk, dander of dog, weed mixture, farina and dander of cat. The more higher positive rates of dust mite, fungus, house dust, milk, dander of dog, dander of cat, eggs were found in teenager group than adult group (P < 0.05). There were more higer positive rates of weed mixture, farina, cashew, cockroaches and crab in teenager group than adult group (P < 0.05). There was no significant difference of positive rate between female group and male group. There was significant difference of variation with seasons. Dust mite, fungus and house dust were the most common allergens among patiens with allergic rhinitis in Changzhou area. The positive rates of allergens varied with ages and seasons.

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.

Objectives To compare the efficacy and tolerability of butterbur (Petasites hybridus) with cetirizine in patients with seasonal allergic rhinitis (hay fever). Design Randomised, double blind, parallel group comparison. Setting Four outpatient general medicine and allergy clinics in Switzerland and Germany. Participants 131 patients were screened for seasonal allergic rhinitis and 125 patients were randomised (butterbur 61; cetirizine 64). Interventions Butterbur (carbon dioxide extract tablets, ZE 339) one tablet, four times daily, or cetirizine, one tablet in the evening, both given for two consecutive weeks. Main outcome measures Scores on SF-36 questionnaire and clinical global impression scale. Results Improvement in SF-36 score was similar in the two treatment groups for all items tested hierarchically. Butterbur and cetirizine were also similarly effective with regard to global improvement scores on the clinical global impression scale (median score 3 in both groups). Both treatments were well tolerated. In the cetirizine group, two thirds (8/12) of reported adverse events were associated with sedative effects (drowsiness and fatigue) despite the drug being considered a non-sedating antihistamine. Conclusions The effects of butterbur are similar to those of cetirizine in patients with seasonal allergic rhinitis when evaluated blindly by patients and doctors. Butterbur should be considered for treating seasonal allergic rhinitis when the sedative effects of antihistamines need to be avoided. What is already known on this topicSeasonal allergic rhinitis (hay fever) is common in countries with temperate climates.Most patients have their symptoms treated for short periods, particularly during peaks in atmospheric pollen countWhat this study addsAfter two weeks, the effects of butterbur and cetirizine were comparable in patients with hay feverButterbur produced fewer sedating effects than cetirizineButterbur should be considered when the sedating effects of

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

Turbinoplasty is a procedure that aims to reduce the size of the inferior turbinate through exuberant bone removal with high mucosal preservation. The procedure is recommended for patients with or without allergic rhinitis and those showing irreversible hypertrophy of inferior turbinates. To evaluate the efficacy of inferior turbinoplasty for obstructive and non-obstructive symptoms in patients with or without allergic rhinitis. Prospective study with 57 patients who underwent inferior turbinoplasty. They were evaluated for nasal obstruction, snoring, facial pressure, smell alterations, sneezing, nasal itching and runny nose symptoms, surgery time, and intraoperative bleeding. The last evaluation took place three months after surgery. Thirty-nine patients with allergic rhinitis and 18 without were assessed. Ninety days after surgery, 94.7% of patients showed degrees IV and V of breathing improvement; 89.5% showed moderate or complete improvement in snoring; all patients showed smell improvement (only one showed moderate improvement; all the others had full improvement); 95.5% experienced complete facial pressure improvement; and 89.7% showed moderate to complete improvement in nasal itching and runny nose symptoms, as well as in sneezing. The efficacy of inferior turbinoplasty was confirmed not only for obstructive symptoms, but also for non-obstructive symptoms in patients with and without allergic rhinitis.

Aim To determine the association between allergic rhinitis, bottle feeding, non‐nutritive sucking habits, and malocclusion in the primary dentition. Methods Data were collected on 1160 children aged 4–5 years, who had been longitudinally followed since the age of 4 months, when they were admitted to nurseries in a suburban area of Tampico–Madero, Mexico. Periodically, physical examinations were conducted and a questionnaire was given to their parents or tutors. Results Malocclusion was detected in 640 of the children (51.03% had anterior open bite and 7.5% had posterior cross‐bite). Allergic rhinitis alone (adjusted odds ratio = 2.87; 95% CI 1.57 to 5.25) or together with non‐nutritive sucking habits (adjusted odds ratio = 3.31; 95% CI 1.55 to 7.09) had an effect on anterior open bite. Bottle feeding alone (adjusted odds ratio = 1.95; 95% CI 1.07 to 3.54) or together with allergic rhinitis (adjusted odds ratio = 3.96; 95% CI 1.80 to 8.74) had an effect on posterior cross‐bite. Posterior cross‐bite was more frequent in children with allergic rhinitis and non‐nutritive sucking habits (10.4%). Conclusions Allergic rhinitis alone or together with non‐nutritive sucking habits is related to anterior open bite. Non‐nutritive sucking habits together with allergic rhinitis seem to be the most important factor for development of posterior open bite in children under the age of 5 years. PMID:16769710

Opinion Statement A high proportion of suicides visit their medical provider in the month prior to death, but depression, suicidal thoughts, and substance use are seldom addressed. For the clinicians routinely treating a substantial patient population with allergic diseases, there are additional concerns, as allergy has been linked with both depression and suicidal behavior. While psychotropic medications may affect diagnosis of allergies, medications used to treat allergies impact mood and behavior. Thus, we present an overview of the overlap of allergic rhinitis with depression and suicidal behavior in adults, based on clinical and epidemiological data, and our research and clinical experience. In summary, we suggest: 1) inquiring among patients with allergies about personal and family history of depression, substance use disorders, suicidal ideation and attempts 2) increased mindfulness regarding the potential effects of allergy medications on mood and behavior; and 3) for people identified with certain types of depression or increased suicide risk, a systematic multilevel collaborative approach. While for practical reasons the majority of patients with depression will continue to be treated by general or family practitioners, the allergy-treating provider should always consider integrated care for bipolar, psychotic or suicidal depression and incomplete remission, or relapsing and highly recurrent course. While awaiting results of much needed basic and clinical research to guide clinical approach for patients with comorbid allergic rhinitis and depression, the simple steps recommended here are expected to improved clinical outcomes in depression, including, on a large scale, reduced premature deaths by suicide.

2016-01-01

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

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. 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. 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. Although allergic rhinitis is a chronic disease and effects quality of life, there were no identifiable negative effects on IQ.

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.

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.

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.

2015-01-01

Pollen food allergy syndrome (PFAS), also called oral allergy syndrome, is a form of food allergy in which uncooked foods cause allergic symptoms generally limited to the oral mucosa. It occurs in a subset of patients with pollen allergy, although not all patients have prominent rhinitis symptoms. PFAS is related to antigenic similarity between the pollen and food allergen. The size of skin test reactions in a group of subjects with pollen sensitivity with PFAS was compared with a group of subjects who were pollen sensitive and without PFAS. Self-reported rhinitis symptoms between the two groups were compared to identify if symptom severity differed. Twenty subjects with PFAS and 20 subjects with seasonal allergic rhinitis without PFAS were enrolled in the study. All the subjects underwent standard skin-prick testing to a panel of common allergens, including select fresh fruits and vegetables. The subjects completed a Mini Rhinoconjunctivitis Quality of Life Questionnaire as part of their clinical evaluation. The subjects with PFAS and those without PFAS were compared statistically. The subjects with PFAS had significantly larger-sized skin-prick test results specific to pollens (p < 0.05). Despite the larger-sized skin-prick test results, the subjects with allergic rhinitis and PFAS reported milder nasal symptoms in relation to pollen skin test result size when compared with allergic rhinitis controls without PFAS. Our study outlined basic differences between two seemingly similar patient groups with a particularly striking discordance between skin test result sizes and rhinitis symptoms. This discordance should be explored further to increase mechanistic understanding of allergen cross-reactivity in PFAS.

This EAACI position paper aims at providing a state-of-the-art overview on nonallergic rhinitis (NAR). A significant number of patients suffering from persistent rhinitis are defined as nonallergic noninfectious rhinitis (NANIR) patients, often denominated in short as having NAR. NAR is defined as a symptomatic inflammation of the nasal mucosa with the presence of a minimum of two nasal symptoms such as nasal obstruction, rhinorrhea, sneezing, and/or itchy nose, without clinical evidence of endonasal infection and without systemic signs of sensitization to inhalant allergens. Symptoms of NAR may have a wide range of severity and be either continuously present and/or induced by exposure to unspecific triggers, also called nasal hyperresponsiveness (NHR). NHR represents a clinical feature of both AR and NAR patients. NAR involves different subgroups: drug-induced rhinitis, (nonallergic) occupational rhinitis, hormonal rhinitis (including pregnancy rhinitis), gustatory rhinitis, senile rhinitis, and idiopathic rhinitis (IR). NAR should be distinguished from those rhinitis patients with an allergic reaction confined to the nasal mucosa, also called "entopy" or local allergic rhinitis (LAR). We here provide an overview of the current consensus on phenotypes of NAR, recommendations for diagnosis, a treatment algorithm, and defining the unmet needs in this neglected area of research. © 2017 EAACI and John Wiley and Sons A/S.

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.

Background Allergic sensitization and filaggrin gene (FLG) variants are important risk factors for allergic disorders; however, knowledge on their individual and interactive effects on the coexistence of eczema, asthma, and rhinitis is lacking. Objective This study aimed at investigating the single and combined effects of allergic sensitization and FLG variants on the development of single and multiple allergic disorders. Methods The Isle of Wight Birth Cohort (n = 1,456) has been examined at 1, 2, 4, 10, and 18 years of age. Repeated measurements of eczema, asthma, rhinitis, and skin prick tests were available for all follow-ups. FLG variants were genotyped in 1,150 participants. Associations of allergic sensitization and FLG variants with single and multiple allergic disorders were tested in log-binomial regression analysis. Results The prevalence of eczema-, asthma-, and rhinitis-only ranged from 5.6% to 8.5%, 4.9% to 10.2%, and 2.5% to 20.4%, respectively, during the first 18 years of life. The coexistence of allergic disorders is common, with approximately 2% of the population reporting the comorbidity of “eczema, asthma, and rhinitis” during the study period. In repeated measurement analyses, allergic sensitization and FLG variants, when analyzed separately, were associated with having single and multiple allergic disorders. Of particular significance, their combined effect increased the risk of “eczema and asthma” (RR = 13.67, 95% CI: 7.35 – 25.42), “asthma and rhinitis” (RR = 7.46, 95% CI: 5.07 – 10.98), and “eczema, asthma, and rhinitis” (RR = 23.44, 95% CI: 12.27 – 44.78). Conclusions and Clinical Relevance The coexistence of allergic disorders is frequent and allergic sensitization and FLG variants jointly increased risk of allergic comorbidities, which may represent more severe and complex clinical phenotypes. The interactive effect and the elevated proportion of allergic comorbidities associated with allergic sensitization and FLG

Allergic diseases are on the rise in many parts of the world, including the Asia-Pacific (APAC) region. Second-generation antihistamines are the first-line treatment option in the management of allergic rhinitis and urticaria. International guidelines describe the management of these conditions; however, clinicians perceive the additional need to tailor treatment according to patient profiles. This study serves as a consensus of experts from several countries in APAC (Hong Kong, Malaysia, the Philippines, Singapore, Thailand, Vietnam), which aims to describe the unmet needs, practical considerations, challenges, and key decision factors when determining optimal second-generation antihistamines for patients with allergic rhinitis and/or urticaria. Specialists from allergology, dermatology, and otorhinolaryngology were surveyed on practical considerations and key decision points when treating patients with allergic rhinitis and/or urticaria. Clinicians felt the need for additional tools for diagnosis of these diseases and a single drug with all preferred features of an antihistamine. Challenges in treatment include lack of clinician and patient awareness and compliance, financial constraints, and treatment for special patient populations such as those with concomitant disease. Selection of optimal second-generation antihistamines depends on many factors, particularly drug safety and efficacy, impact on psychomotor abilities, and sedation. Country-specific considerations include drug availability and cost-effectiveness. Survey results reveal bilastine as a preferred choice due to its high efficacy and safety, suitability for special patient populations, and the lack of sedative effects. Compliance to the international guidelines is present among allergists, dermatologists and otorhinolaryngologists; however, this is lower amongst general practitioners (GPs). To increase awareness, allergy education programs targeted at GPs and patients may be beneficial. Updates to

It remains uncertain whether intake of fish or n-3 polyunsaturated fatty acids is preventive against allergic disorders. This cross-sectional study investigated the association of intake of selected high-fat foods and specific types of fatty acids with the prevalence of allergic rhinitis in Japan where intake of fish is high. Study subjects were 1002 Japanese pregnant females. Allergic rhinitis (including cedar pollinosis) was defined as present if subjects had received drug treatment at some point during the previous 12 months. Information on dietary factors was collected using a validated self-administered diet history questionnaire. Adjustment was made for age, gestation, parity, cigarette smoking, passive smoking at home and at work, indoor domestic pets, family history of asthma, atopic eczema, and allergic rhinitis, family income, education, mite antigen level in house dust, changes in diet in the previous month, season when data were collected, and body mass index. There was a tendency for an inverse dose-response association between fish intake and allergic rhinitis although the adjusted odds ratio for comparison of the highest with the lowest quartile was not statistically significant (p for trend = 0.09). Intake of eicosapentaenoic and docosahexaenoic acids was independently associated with a decreased prevalence of allergic rhinitis: the multivariate odds ratio for the highest quartile was 0.56 (95% confidence interval: 0.32-0.96, p for trend = 0.03). Intake of n-6 polyunsaturated fatty acids in the third quartile but not the second and fourth quartiles showed a tendency for an inverse association with the prevalence of allergic rhinitis. No measurable relationship was found between consumption of meat, eggs, dairy products, total fat, saturated, monounsaturated, and n-3 polyunsaturated fatty acids, and cholesterol or the ratio of n-3 to n-6 polyunsaturated fatty acids and allergic rhinitis. Our findings suggest that the intake of eicosapentaenoic and

Although work-related asthma and allergies are a huge burden for society, investigation of occupational exposures in early work life using an unexposed reference group is rare. Thus, the present analyses aimed to assess the potential impact of occupational exposure and other risk factors on the prevalence of work-related sensitisation and incidence of allergic rhinitis/asthma using a population-based approach and taking into account an unexposed reference group. In SOLAR (Study on Occupational Allergy Risks) II, German participants of ISAAC (International Study of Asthma and Allergies in Childhood) phase II were followed from childhood (9-11 years) until early adulthood (19-24 years). Data on 1570 participants were available to fit predictive models. Occupational exposure was not statistically significantly associated with disease prevalence/incidence. Sensitisation in childhood, parental asthma, environmental tobacco smoke exposure during puberty, sex and study location were statistically significant predictors of outcome. Our results indicate that occupational exposure is of little relevance for work-related sensitisation prevalence and allergic rhinitis/asthma incidence in early work life, while other risk factors can be used to improve career guidance for adolescents. Further research on the role of a potential healthy hire effect and the impact of longer exposure duration is needed. ©ERS 2014.

Nasal inflammation in allergic rhinitis enhances bronchial Th2 driven inflammation and development of asthma. We assessed bronchial inflammation induced by natural allergen exposure during pollen season in patients with pollinosis with or without asthma to show the intensity of inflammation in asthma and rhinitis and possible persistence of inflammation in periods without allergen exposure. Sputum was induced in 52 patients with seasonal allergic rhinitis without asthma, 38 patients with seasonal allergic rhinitis and seasonal asthma and 23 healthy volunteers. Sampling was performed 6-8 weeks before the expected beginning of symptoms, during symptomatic period and 6-8 weeks after the end of symptoms. Sputum ECP was measured by means of chemi-luminiscent immunometric assay and sputum cell counts were assessed by classical staining and immunocytochemistry. Sputum eosinophils were on the whole higher in both asthma and rhinitis compared to controls (p<0.001, p=0.003). The rise of eosinophils during pollen season compared with values out of pollen season was significant in asthma (classical staining) (p=0.014) and slightly apparent in rhinitis (immunocytochemistry) (p=0.073). The seasonal rise of sputum ECP was observed only in rhinitis (p=0.006). Inflammation of the lower airway in patients with allergic rhinitis with and without asthma has been confirmed by means of both sputum eosinophil count and sputum ECP level. Persistent inflammation of lower airway in periods without allergen exposure was proven in seasonal asthma. This may have implications for the therapy of seasonal allergic rhinitis with and without asthma in terms of promoting long-term anti-inflammatory treatment. Copyright © 2013 SEICAP.

Allergic Rhinitis Control Test(ARCT) has been validated in allergic rhinitis(AR) step-up pharmacotherapy management approach. The aim of our study was to evaluate the potential of ARCT in AR step-down pharmacotherapy. In an open-labelled randomized controlled study, AR patients controlled with intranasal corticosteroid(INS) plus antihistamine(step 4) were included and randomized into an ARCT or a control group. In ARCT group, the patients were followed up every 15 days; if ARCT score was ≥20(controlled AR), the patient would step down to step 3(INS), step 2(daily antihistamine), step 1(antihistamine as needed) and step 0(no medication) consecutively; if ARCT score was strictly <20, the treatment would not be adjusted. In the control group, patients would be treated with step 4 medications during the whole study. Rhinitis Quality-of-Life Questionnaire(RQLQ), Morisky Questionnaire and Brief Illness-Perception-Questionnaire(B-IPQ) were completed at baseline and the end of the study. Medication use and side effects were recorded. A total of 255 AR patients were enrolled into the study, 27 patients dropped out. The control rates at D45 were 77.8% in ARCT group and 85.8% in control group(P>0.05). ARCT group had less mean medication use than control group(INS 1.27 vs. 2.22 bottle, antihistamines 35.9 vs. 61.4 tablets)(P<0.05). RQLQ, Morisky and B-IPQ score were significantly improved in both groups after treatment(P<0.05). Stepping down AR medications in controlled patients led to similar clinical outcomes at reduced cost compared with those who maintained their current treatment level. ARCT is an optimal tool for evaluating the step-down eligibility. Copyright © 2018. Published by Elsevier Inc.

Allergic rhinitis is usually treated with oral antihistamines or nasal steroids. Topically active nasal antihistamine is a new treatment modality for allergic rhinitis. The efficacy in comparison to well established topical treatment alternatives is not fully known. To compare the efficacy of intranasally administered azelastine to budesonide, at their respectively recommended dosage, on the symptoms of perennial rhinitis patients. A placebo-controlled, randomized, parallel group study was conducted to compare the efficacy and tolerability of intranasal budesonide aqueous suspension (256 microg once daily) with azelastine hydrochloride nasal spray (280 microg twice daily (560 microg/day)) and with placebo in the treatment of perennial allergic rhinitis. The 195 patients (with at least a 2-year history of perennial allergic rhinitis) recorded individual nasal symptom scores, the degree of symptom control achieved and any adverse events experienced over a 2-week baseline period and a 6-week treatment period. Following treatment, the reductions in mean combined and individual nasal symptom scores from baseline values were significantly greater in the budesonide group compared with the placebo group (P < .0001 for all variables except runny nose P = .01). In patients treated with budesonide, there were also significantly larger reductions from baseline values in combined nasal symptom scores (P < .01) and in scores for all individual nasal symptoms (P < or = .05) compared with those treated with azelastine. The reductions from baseline in both combined and individual nasal symptom scores did not differ between azelastine and placebo. The study medications were well tolerated, producing no unexpected or serious treatment-related adverse events. A once-daily dose of 256 microg of intranasal budesonide aqueous suspension is significantly more effective at relieving the symptoms of perennial allergic rhinitis compared with a twice daily dose of 280 microg of azelastine

Encasing bedding in impermeable covers reduces exposure to house-dust mites, but the clinical benefit of this intervention as part of mite-avoidance measures for patients with allergic rhinitis is not known. We performed a multicenter, randomized, placebo-controlled trial of one year of use of impermeable bedding covers in the bedrooms of patients with rhinitis who were sensitized to house-dust mites to determine the effects on the signs and symptoms of disease. Three participating university medical centers enrolled 279 patients with allergic rhinitis who were randomly assigned to receive impermeable or non-impermeable (control) covers for their mattress, pillow, and duvet or blanket. At the start of the study, all participants received information on general allergen-avoidance measures. The severity of rhinitis was measured on a rhinitis-specific visual-analogue scale and by means of a daily symptom score and nasal allergen provocation testing. We also measured the concentrations of Dermatophagoides pteronyssinus (Der p1) and D. farinae (Der f1) in dust from patients' mattresses, bedroom floors, and living-room floors at base line and after 12 months as a measure of the efficacy of the intervention. A total of 232 patients completed the study. There was a significant reduction in Der p1 and Der f1 concentrations in the mattresses of the impermeable-cover group, whereas there was no significant reduction in the control group. However, there was no significant effect on the clinical outcome measures. Analyses of subgroups defined according to age, level of exposure, type and severity of sensitization, or characteristics of the patient's home had similar results. Mite-proof bedding covers, as part of a structured allergy-control program, reduced the level of exposure to mite allergens. Despite the success of the intervention, this single avoidance measure did not lead to a significant improvement of clinical symptoms in patients with allergic rhinitis. Copyright

Risk factors for allergic rhinitis (AR) in asthmatics are likely distinct from those for AR or asthma alone. We sought to identify clinical and environmental risk factors for AR in children with asthma. We performed a cross-sectional study of 616 Costa Rican children aged 6-14 years with asthma. Candidate risk factors were drawn from questionnaire data, spirometry, methacholine challenge testing, skin testing, and serology. Two outcome measures, skin test reaction (STR)-positive AR and physician-diagnosed AR, were examined by logistic regression. STR-positive AR had high prevalence (80%) in Costa Rican children with asthma, and its independent risk factors were nasal symptoms after exposure to dust or mold, parental history of AR, older age at asthma onset, oral steroid use in the past year, eosinophilia, and positive IgEs to dust mite and cockroach. Physician-diagnosed AR had lower prevalence (27%), and its independent risk factors were nasal symptoms after pollen exposure, STR to tree pollens, a parental history of AR, inhaled steroid and short-acting beta2 agonist use in the past year, household mold/mildew, and fewer older siblings. A physician's diagnosis was only 29.5% sensitive for STR-positive AR. Risk factors for AR in children with asthma depend on the definition of AR. Indoor allergens drive risk for STR-positive AR. Outdoor allergens and home environmental conditions are risk factors for physician-diagnosed AR. We propose that children with asthma in Costa Rica and other Latin American nations undergo limited skin testing or specific IgE measurements to reduce the current under-diagnosis of AR.

The prevalence of allergic disorders, including asthma, atopic dermatitis, and allergic rhinitis has been increasing, and the prevalence of Helicobacter pylori (H. pylori) infection has been decreasing. Chronic bacterial infection during childhood is reported to protect the development of allergic diseases. The aim of the present study was to identify whether H. pylori infection influences the prevalence of allergic rhinitis, which has become a serious social problem, especially in the developed countries. We initially investigated the association between the prevalence of H. pylori and pollinosis symptoms in 97 healthy volunteers. We had investigated the association between the serum H. pylori-immunoglobulin (Ig) G antibodies and specific IgE antibodies for pollen, mites, and house dust in 211 consecutive patients. There were 52.2% (36/69) of H. pylori-negative volunteers with allergic symptoms, which was significantly higher than H. pylori-positive volunteers (14.3%, 4/28, P < 0.05). The risk of pollinosis symptoms by H. pylori infection was 0.148 (95% confidence interval): 0.046-0.475, P < 0.05). The prevalence of H. pylori infection increased according to age, whereas that of specific IgE-positive patients gradually decreased. Among the IgE-positive patients, the prevalence of H. pylori-negative patients was significantly higher than H. pylori-positive patients who were younger in age (P < 0.05). H. pylori infection decreased the pollinosis effects, especially among the younger volunteers. However, the prevalence of pollinosis in patients who were 50 years or older were almost same between H. pylori-positive and H. pylori-negative patients; therefore, the recent increase of pollinosis might relate to not only H. pylori infection, but also change in social environment.

Allergic rhinitis (AR) is a global health problem affecting many people from childhood to adulthood. The aim of this study was to evaluate the prevalence of AR and related symptoms, and to assess the risk factors, dietary habits and the Mediterranean diet affecting AR. In a cross-sectional study design, 9991 children, aged 13-14 years in 61 primary schools in 32 districts of Istanbul were evaluated. The prevalence of AR symptoms among the children was evaluated using the ISAAC protocol. In our study, total of 10,984 questionnaires were distributed to 13-14yr-old schoolchildren to 61 schools in 32 district of Istanbul and 9991 questionnaires were suitable for analysis with an overall response of 91.7%. The rates of lifetime rhinitis, rhinitis in last 12 months and lifetime doctor diagnosed AR prevalence were 53.5%, 38.3% and 4.5%, respectively. The variation among districts in the prevalence of doctor diagnosed AR was very high. The highest prevalence was about 10 times higher than in the district with the lowest prevalence (range: 1.4-14.5) of Istanbul. A family history of atopy, mother with a university degree, presence of cat at home during last 12 months and adenoidectomy were significant for increased doctor diagnosed AR risk. Additionally, although fish and other sea foods, fermented drinks made from millets and various seeds, animal fats and butter were independent risk factors for doctor diagnosed AR, fish oil and hamburger were protective foods for doctor diagnosed AR. The MD was not associated with the prevalence of doctor diagnosed AR. This study shows that that there are wide variations for the prevalence of AR related symptoms in 13-14yr-old schoolchildren among districts of Istanbul in Turkey. Socio-economical, environmental factors, some dietary habits, but not Mediterranean diet may affect the prevalence of AR. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Background Allergic rhinitis is the most common allergic disorder. Although the management of the disease is successful in many patients, based on guidelines, some of them remain with symptoms uncontrolled with pharmacotherapy. Presently, there is no substantiated information on the control of allergic rhinitis in patients who underwent sublingual immunotherapy. Objective The purpose of this prospective follow-up study was to assess the control of allergic rhinitis in adults after a three-year course of house dust mite sublingual immunotherapy. Methods This prospective real-life study was designed to include adults with moderate to severe allergic rhinitis sensitized to house dust mite who underwent a three-year course of sublingual immunotherapy. Control of symptoms was assessed by Rhinitis Control Assessment Test (RCAT) after three years of house dust mite sublingual immunotherapy. Additionally, patients assessed their symptoms by utilizing a visual analog scale. Results A total number of 86 consecutively enrolled patients (46 (53.49%) men; mean age 26.10 years (SD = 5.85)) with moderate to severe allergic rhinitis and clinically relevant sensitization to house dust mite were evaluated. When assessed by RCAT on the third year, 74 (86.05%) had well-controlled symptoms and 20 (27.03%) of them were completely controlled. A significant reduction in visual analog scale scores-from 7.52 cm at baseline to 2.31 cm-was established ( P < 0.0001). There was a strong negative correlation between RCAT scores and visual analog scale (r = -0.65; P < 0.01). Conclusion This study provided evidence that a three-year course of house dust mite sublingual immunotherapy appears effective in controlling the symptoms of allergic rhinitis.

Certain occupational groups are known to be at particularly high risk of developing allergic diseases. The objective of the present study was to evaluate the prevalence of allergic diseases among working adolescents. The International Study of Asthma and Allergies in Childhood questionnaire was used. Four hundred and thirty six adolescents working in motor, lathe-finish, coiffure and textile and 366 high school students as control group were enrolled to the study. Mean age was 16.8 +/- 1.2 years and 82.9% of them were male. There was no significant difference among groups for ever and current wheezing while doctor diagnosed asthma was higher in lathe- finish group (p = 0.036). Family history of allergy, history of allergic rhinitis, and active smoking were found to be risk factors for asthma and related symptoms. Working in coiffure (p = 0.054), and textile (p = 0.003) were significant risk factors for ever allergic rhinitis. Working in lathe finish (p = 0.023), coiffure (p = .002), and textile (p < 0.001) were associated with a higher risk for current allergic rhinitis. Working in coiffure was a risk factor for ever eczema (p = 0.008) and doctor diagnosed eczema (p = 0.014). It was concluded that working in lathe-finish was associated with doctor diagnosed asthma and active smoking was a risk factor for asthma and related symptoms. Working in coiffure, textile and lathe- finish were risk factors for rhinitis, and working in coiffure was a risk factor for eczema. Preventive measures should be taken at the onset of employment in order to prevent or reduce the detrimental effects of exposures in these occupational groups.

Multimorbidity in allergic airway diseases is well known, but no data exist about the daily dynamics of symptoms and their impact on work. To better understand this, we aimed to assess the presence and control of daily allergic multimorbidity (asthma, conjunctivitis, rhinitis) and its impact on work productivity using a mobile technology, the Allergy Diary. We undertook a 1-year prospective observational study in which 4 210 users and 32 585 days were monitored in 19 countries. Five visual analogue scales (VAS) assessed the daily burden of the disease (i.e., global evaluation, nose, eyes, asthma and work). Visual analogue scale levels <20/100 were categorized as "Low" burden and VAS levels ≥50/100 as "High" burden. Visual analogue scales global measured levels assessing the global control of the allergic disease were significantly associated with allergic multimorbidity. Eight hypothesis-driven patterns were defined based on "Low" and "High" VAS levels. There were <0.2% days of Rhinitis Low and Asthma High or Conjunctivitis High patterns. There were 5.9% days with a Rhinitis High-Asthma Low pattern. There were 1.7% days with a Rhinitis High-Asthma High-Conjunctivitis Low pattern. A novel Rhinitis High-Asthma High-Conjunctivitis High pattern was identified in 2.9% days and had the greatest impact on uncontrolled VAS global measured and impaired work productivity. Work productivity was significantly correlated with VAS global measured levels. In a novel approach examining daily symptoms with mobile technology, we found considerable intra-individual variability of allergic multimorbidity including a previously unrecognized extreme pattern of uncontrolled multimorbidity. © 2018 EAACI and John Wiley and Sons A/S.

Background Numerous studies have suggested that nutritional intake is related to allergic diseases. Although conflicting results exist, fat intake is often associated with allergic diseases. We investigated the relationship between allergic diseases and nutritional intake after adjusting for various demographic and socioeconomic factors in a large, representative sample of Korean children. Methods A total of 3,040 participants, aged 4 to 13 years old, were enrolled in the present study from the Korean National Health and Nutrition Examination Survey (KNHANES), 2010–2012. Nutritional intake data, including total calories, protein, fat, carbohydrate, vitamin A, vitamin C, thiamine, riboflavin, and niacin, were retrieved from the survey using the complete 24-hour recall method. The associations between each nutritional factor and allergic rhinitis/asthma/atopic dermatitis were analyzed using simple and multiple logistic regression analyses with complex sampling. Age, sex, body mass index (BMI), number of household members, income level, and region of residence were adjusted for as covariates. Results Of the participants, 22.1%, 6.0%, and 15.5% suffered from allergic rhinitis, asthma, and atopic dermatitis, respectively. Allergic rhinitis was significantly correlated with high-fat and low-carbohydrate diets. The adjusted odds ratio (AOR) was 1.25 (95% CIs = 1.06–1.46, P = 0.007) for fat intake, denoting a 10% increase. Carbohydrate intake (10% increase) was negatively related to allergic rhinitis with an AOR of 0.84 (95% CIs = 0.74–0.95, P = 0.004). No other significant relationships were found between the retrieved nutritional factors and either asthma or atopic dermatitis. Conclusion Allergic rhinitis was related to high-fat and low-carbohydrate diets. Although the underlying mechanisms and causal relationships remain elusive, the present study provides reliable evidence regarding the associations between nutritional factors and allergic rhinitis by considering

Montelukast sodium (Singulair, Merck and Co., Inc., Whitehouse Station, NJ) is a selective and orally-active leukotriene receptor antagonist with demonstrated effectiveness for treating allergic asthma and allergic rhinitis in adults and children as young as 12 months of age for allergic asthma and 6 months of age for allergic rhinitis. It was recently approved in the US for prevention of exercise-induced bronchoconstriction in patients who are > or = 15 years of age. This paper updates a prior review of the data on the clinical efficacy of montelukast published in this journal.

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. Copyright © 2015 Elsevier GmbH.

The present study aimed to investigate the correlation between asthma or allergic rhinitis and employment in the palm tree gardens of Jahrom, Iran. This was a cross-sectional study including 50 palm tree garden workers and a control group of 50 office employees. Data collection included demographics, as well as standard International Study of Asthma and Allergies in Childhood (ISAAC) and A New Symptom-Based Questionnaire for Predicting the Presence of Asthma (ASQ) questionnaires. Data were analyzed using SPSS22. Descriptive statistics, chi-square test, t-test, and logistics regression were used to analyze data. The correlation between asthma and occupation was significant ( P=0.046); and asthma prevalence was higher in palm tree garden workers. However, no relationship was observed between age, duration of employment, smoking cigarettes, hookah, or opium addiction with asthma. Furthermore, in this study, no significant relation was observed between the prevalence of asthma and contact with dust, contact with pets' skin and hair, family history of asthma, or the use of perfume and air freshener. The symptoms of allergic rhinitis (including sneezing, runny nose, and blocked nose) were significantly greater in palm tree garden workers (P=0.038). These symptoms in both workers and office employees were higher in spring. In our study, allergic rhinitis and asthma were more common in palm tree garden workers than in the general population. According to our study, people working in this occupation should take necessary precautions.

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.

National epidemiological study to observe if among patients with pollinic seasonal allergic rhinitis (SAR), there are differences between those visited by primary care physicians (GPs) or allergists (ALs). 758 and 739 adults were recruited respectively by GPs and ALs. The physicians filled in a questionnaire: ARIA classification, prescribed treatment, and asthma incidence. The patient completed a visual analogical scale (VAS) to evaluate the severity of the rhinitis. Rhinitis control (controlled, partially controlled, and not controlled) was assessed by physician and patient. No significant differences were found among patients visited by GPs or ALs concerning the ARIA classification and rhinitis severity. Treatment with oral antihistamines was 92.3% and 89.3% for GPs and ALs, respectively. The use of nasal corticosteroids was 76.7% and 60.4% for GP and AL patients, respectively. 31.9% of the patients visited by the ALs were treated with immunotherapy. The use of alternative medicine was 10.9% and 7.6% in GP and AL patients, respectively. The perception of "controlled" rhinitis was similar among patients (40.0%) and doctors (40.1%), although patients referred differences depending if they were visited by GP (44.8%) or AL (34.9%). Asthma prevalence was higher in those who suffered persistent as compared to intermittent rhinitis (OR=1.81, 95% CI: 1.39-2.36, p<0.001), and moderate/severe vs. mild rhinitis (OR=1.68, 95% CI: 1.05-2.68, p=0.029). The patients with pollinic SAR visited by GPs or ALs show no differences in severity. Less than half of the patients can be considered as "controlled". Copyright © 2011 SEICAP.

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.

Fentanyl pectin nasal spray (FPNS, Lazanda® in the US and PecFent® in Europe and Australia) is a novel analgesic approved for the management of breakthrough pain in cancer patients. Given that the fentanyl is nasally administered, it is important to understand whether concomitant allergic rhinitis, or its treatment with a vasoconstrictor, would affect its absorption and, potentially, its efficacy or safety. Subjects with a history of allergic rhinitis were screened to identify subjects who developed at least moderate rhinitis symptoms on exposure to pollen allergen (either ragweed or tree) in an environmental exposure chamber (EEC). These were entered into a randomized, three-way crossover study in which each subject received 100 μg of FPNS under three exposure conditions; Control (no rhinitis), Rhinitis (symptomatic without decongestant), Treated (symptomatic with concomitant oxymetazoline). Blood samples for fentanyl were collected over a 24-hour period. A total of 132 subjects was screened to identify 54 for inclusion in the study; 31 were evaluable for pharmacokinetics. Measures of fentanyl absorption (mean or median) were similar between Control and Rhinitis conditions: Cmax 453.0 vs. 467.8 pg/ml; AUCt 1,292.3 vs. 1,325.4 pg×h/ml, AUC0-∞ 1,430.6 vs. 1,387 pg×h/ml and tmax 20 vs. 17 minutes. When oxymetazoline was co-administered, overall fentanyl absorption was slightly reduced (AUC0-∞ 1,362.4 pg×h/ml); but, more clinically relevant were the delayed rate of absorption (tmax 53 minutes) and reduced Cmax (235.3 pg/ml). Patients treated with FPNS will be unaffected by the development of allergic rhinitis; but, if oxymetazoline is prescribed, the patient would benefit from added supervision when oxymetazoline is started and stopped.

Parental allergy-related disease increases the risk for rhinitis, but it remains unknown how different phenotypes of parental allergy affect this risk. The aim of this study was to investigate how parental hay fever, asthma, and eczema affect the risk of allergic rhinitis (AR) and nonallergic rhinitis (NAR) at 8 years of age. Information on 2413 children from a population-based birth cohort was used combining questionnaire data and IgE to inhalant allergens. Logistic regression was used to estimate the association between parental allergy-related disease and AR and NAR. In addition, cluster analysis was used to search for latent phenotypes of heredity likely to be associated with AR and NAR. At age 8 years, 13.8% of the children had AR, while 6.4% had NAR. Parental isolated hay fever increased the odds of AR (OR 2.2, 95% CI 1.6-3.2), whereas isolated asthma or eczema did not. The odds of NAR increased when one parent had two or more allergy-related diseases. In the cluster analysis, the highest proportion of AR, 37.5%, was seen in a cluster where both parents had hay fever and pollen allergy and that of NAR, 11.0%, in a cluster where one parent had hay fever, pollen allergy, and eczema. Parental allergy-related disease may be an important risk factor for NAR as well as AR, and the risk is comparable for maternal and paternal allergy. Parental hay fever seems to be the dominating hereditary risk factor for AR. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Rhinophototherapy: gimmick or an emerging treatment option for allergic rhinitis?

Photodynamic therapy has been used in treating immune-mediated dermatological conditions such as psoriasis and atopic dermatitis. There are emerging reports on the efficacy of intranasal phototherapy in allergic rhinitis. The aim of this review was to assess intranasal phototherapy in the treatment of allergic rhinitis, with particular emphasis on clinical efficacy, scientific basis and safety. A structured search of the U.S. National Library of Medicine (PubMed), the Cochrane Collaboration library, Google Scholar and ISI Web of Knowledge database was undertaken using MeSH terms `phototherapy` and `rhinitis.` Fourteen full-text articles were available for review. Three different phototherapy medical devices were assessed: (1) Bionase(TM), (2) Allergy Reliever SN206 and (3) Rhinolight(®). Light wavelength used in these devices ranged from red light to ultraviolet. Clinical use of intranasal phototherapy appears to be safe and well tolerated. Most studies demonstrated symptomatic improvement and quality of life scores. No improvement in objective measures of nasal airflow was demonstrated. Beneficial effects of phototherapy on inflammatory markers remain equivocal. Phototherapy treatment results in DNA damage but does not appear to predispose to carcinogenesis. However, long-term prospective studies are required to verify this. The quality of published studies was variable and thus the current strength of recommending intranasal phototherapy is currently weak.

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.

Inverse association between allergic conditions and glioma risk has been consistently reported in epidemiological studies with little attention paid to potential environmental confounders; the association with meningioma risk is less consistent. We examined the association between allergy history and risk of glioma and meningioma in adults using data from the CERENAT (CEREbral tumors: a NATional study) multicenter case-control study carried out in 4 areas in France in 2004-2010. Participants' histories of doctor-diagnosed allergic asthma, eczema, rhinitis/hay fever and other allergic conditions were collected at onset through a detailed questionnaire delivered in a face-to-face interview. Conditional logistic regression for matched sets was adjusted for participants' educational level and mobile phone use. A total of 273 glioma cases, 218 meningioma cases and 982 matched controls selected from the local electoral rolls were analyzed. A significant inverse association was found between glioma and a history of any allergy (OR 0.52, 95% CI 0.36-0.75), with a dose-effect relationship with the number of allergic conditions reported (p-trend = 0.001) and a particularly strong association with hay fever/allergic rhinitis (OR 0.46, 95% CI 0.30-0.72). Interestingly, associations with glioma risk were more pronounced in women. For meningioma, no association was observed with overall or specific allergic conditions. Our findings confirmed the inverse association between allergic conditions and glioma risk but questioned the role of allergy in meningioma risk. Future research is needed to clarify the biological mechanism of overall allergy and allergic rhinitis on glioma and to confirm the different effect by gender.

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

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.

Airborne pollen is a major symptom trigger in allergic rhinitis patients, but the impact of pollen differs among patients and regions and is influenced by environmental factors. To study these complex relationships, there is a need for data on the severity of symptoms in space and time. 'Citizen science' is increasingly recognized as an effective tool to monitor changes in our environment. The aim of this study was to investigate the feasibility of a citizen science-based survey to monitor spatiotemporal variation in allergic rhinitis symptoms. Participants were recruited through the Web site Allergieradar.nl. After registering by completing an extensive questionnaire, they entered (preferably daily) their symptoms of eyes, nose, and lungs on a scale from 1 to 10, as well as their geographic location. The registration questionnaire revealed that the majority of the participants (77%) had physician-diagnosed hay fever and 65% of the participants had been tested positively for their allergy. This study shows that the symptom scores of the participants are related to (i) pollen concentrations in the air, (ii) the self-reported sensitivity profile, and (iii) the sales of prescription antihistamines in The Netherlands. Our data indicate that the collection of allergic rhinitis symptom data by 'citizen science' is feasible and has an added value in studies on the impact of pollen. © 2014 John Wiley & Sons A/S.

Purpose Allergic rhinitis is clinically defined as a disorder of the nose induced by IgE mediated inflammation after allergen exposure of the nasal mucosa. Many reports have stated that Panax ginseng and fermented red ginseng have anti-inflammatory effects, especially against Th2-type inflammation. This study was conducted to evaluate the therapeutic effects of fermented red ginseng in allergic rhinitis. Methods In this 4-week, double-blind, placebo-controlled study, 59 patients with persistent perennial allergic rhinitis were randomly divided into two groups: those receiving fermented red ginseng tablets (experimental group) and those receiving placebo (control group). The primary efficacy variable was the total nasal symptom score (TNSS; rhinorrhea, sneezing, itchy nose, and nasal congestion). Secondary efficacy variables were the Rhinitis Quality of Life (RQoL) score and skin reactivity to inhalant allergens, as determined by the skin prick test. Results There was no significant difference in the TNSS score and TNSS duration score between the experimental and placebo groups in weeks 1, 2, 3, or 4. For nasal congestion, fermented red ginseng was significantly effective (P<0.005), while placebo caused no change. The activity and emotion of RQoL improved markedly secondary to treatment with fermented red ginseng (P<0.05), while placebo caused no change. Additionally, fermented red ginseng reduced skin reactivity to sensitized perennial allergens (P<0.05). Fermented red ginseng was well tolerated. Conclusions Fermented red ginseng improved nasal congestion symptoms and RQoL in patients with perennial allergic rhinitis. PMID:21461249

To explore the relationship between allergic rhinitis (AR) and personality traits in nonpsychiatric population of allergic status. Subjects were assigned to the allergic (84 cases) or nonallergic health group (37 cases) on the basis of skin prick test (SPT) and allergic symptoms. The psychological aspects of subjects were assessed by using the minnesota multiphasic personality inventory (MMPI). The allergic group scored higher than the nonallergic group on five clinical scales, hypochondriasis (Hs), depression (D), hysteria (Hy), hypomania (Ma), social introversion (Si), and one research scale manifest anxiety scale (Mas). The differences were significant (t value was respectively 2.169, 2.711, 2.010, 2.577, 2.390 and 2.196, all P < 0.05). In addition, the grade of resultant skin wheal was positively correlated with T scores on the Hs, Hy, psychopathic deviance (Pd) and psychasthenia (Pt). The r value was 0.366, 0.449, 0.345 and 0.355 respectively (all P < 0.05). Subjects with AR show poorer psychological functioning, indicating the close relationship between AR and psychological status.

In Korea, the prevalence of allergic rhinitis (AR) is increasing, as in other industrialized countries. However, no large population-based study defining risk factors for AR has yet been conducted. The purpose of this study was to evaluate the prevalence and risk factors of AR in large population-based study. A cross-sectional study was performed using data from the Korea National Health and Nutrition Examination Survey. We evaluated data from 31,217 subjects who were interviewed between 2008 and 2011. The prevalence of AR decreased with age (adjusted odds ratio [AOR] = 0.985; 95% CI = 0.984-0.987). Higher-level stress (AOR for severe stress = 1.470; 95% CI = 1.209-1.788); asthma (AOR = 1.868; 95% CI = 1.582-2.205); atopic dermatitis (AOR = 1.552; 95% CI = 1.309-1.841); pulmonary tuberculosis (AOR = 1.320; 95% CI = 1.119-1.555); depression (AOR = 1.250; 95% CI = 1.117-1.400); and thyroid disease (AOR = 1.328; 95% CI = 1.104-1.597) increased the risk of AR. Participants whose parents had a history of AR also had higher AORs (father, AOR = 1.566; 95% CI = 1.130-2.172; mother, AOR = 1.546; 95% CI = 1.190-2.008). Marriage (AOR = 0.846; 95% CI = 0.741-0.966) decreased the risk of AR. Farmers, fishers, laborers, and soldiers were at lower risk of AR. Although high BMI, a high educational level, living in a large household, specific types of daily living, and a history of diabetes mellitus have been reported as risk factors for AR; none of these factors attained statistical significance in the present study. Our study revealed that age, stress level, marriage, occupation, asthma, atopic dermatitis, pulmonary tuberculosis, depression, thyroid disease, and parental AR history, all affected the prevalence of AR. We believe that defining the influence of various factors on AR will help to prevent development of the condition in the future.

To investigate whether there were differences in Th17 cells mediated immunological responses among asthmatics with or without allergic rhinitis. A case-control comparison was conducted in a cohort of 67 children with asthma (AS), 50 children with allergic rhinitis (AR), 52 children with both AS and AR (ASR), 25 infectious rhinitis (IR), and 55 healthy controls (HC). The percentages of circulating Th17 cells were determined by flow cytometry. The Th2- and Th17-related cytokines in plasma and culture supernatants were measured by enzyme-linked immunosorbent assay. The effect of proinflammation cytokine IL-17E on Th2 cytokines production from human T helper (Th) lymphocytes was analyzed. (1) A inter-group comparison revealed that Th17 cells levels were highest in ASR group [(0.89% ± 0.27) %], following by AS group [(0.82 ± 0.29) %] and AR group[(0.78 ± 0.17) %] (P< 0.05). (2) After in-vitro stimulation with house dust mite (HDM) antigen, the levels of IL-4 and IL-17E in culture supernatants of PBMCs from allergic children (AS group, AR group and ASR group) were significantly enhanced. (3) The release of Th2 cytokines from IL-17E treated Th cells of allergic children (AS group, AR group and ASR group) were significantly induced, no similar result was observed in IR group and HC group. Our findings preliminarily revealed that Th17 cell and its related cytokines might be involved in pathogenesis of airway inflammation diseases, and also presenting varying immunological characteristics among asthmatic children with or without allergic rhinitis.

The aim of this study is to formulate criteria for the definition of allergic rhinitis. Other studies have sought to develop scoring systems to categorize the severity of allergic rhinitis symptoms but it was never used for the formulation of diagnostic criteria. These other scoring systems were arbitrarily chosen and were not derived by any statistical analysis. To date, a study of this kind has not been performed. The hypothesis of this study is that it is possible to formulate criteria for the definition of allergic rhinitis. This is the first study to systematically examine and evaluate the relative importance of symptoms, signs and investigative tests in allergic rhinitis. We sought to statistically rank, from the most to the least important, the multiplicity of symptoms, signs and test results. Forty-seven allergic rhinitis and 23 normal subjects were evaluated with a detailed questionnaire and history, physical examination, serum total immunoglobulin E, skin prick tests and serum enzyme allergosorbent tests (EAST). Statistical ranking of variables indicated rhinitis symptoms (nasal, ocular and oronasal) were the most commonly occurring, followed by a history of allergen provocation, then serum total IgE, positive skin prick tests and positive EAST's to house dust mite, perennial rye and bermuda/couch grass. Throat symptoms ranked even lower whilst EAST's to cat epithelia, plantain and cockroach were the least important. Not all symptoms, signs and tests evaluated proved to be statistically significant when compared to a control group; this included symtoms and signs which had been considered historically to be traditionally associated with allergic rhinitis, e.g. sore throat and bleeding nose. In performing statistical analyses, we were able to rank from most to least important, the multiplicity of symptoms signs and test results. The most important symptoms and signs were identified for the first time, even though some of these were not included in our

The epidemic of allergic disease is a major public health crisis. The greatest burden of allergies is in childhood, when rapidly rising rates of disease are also most evident. General practitioners (GP) have a key role in recognising and addressing aller-gy-related problems and identifying whether a child requires referral to a paediatric allergist. This article focuses on IgE-mediated food allergies and allergic rhinitis, the most commonly seen conditions in paediatric im-munology. We will discuss prevention, diagnosis, management and treatment strategies. Currently there is no cure for food allergy. Oral tolerance induction continues to be a significant focus of research. All children with a possible food allergy should be referred to an allergist for further testing and advice. Children who develop allergic rhinitis need a regular review by their GP. Immunotherapy should be discussed early in the disease process and needs to be com-menced by an allergist.

1) To determine whether there is a significant relationship between allergic rhinitis and otitis media with effusion (OME), Eustachian tube dysfunction (ETD), or tympanic membrane retraction (TMR) in children in a nationally representative population; and 2) to determine whether age is an effect modifier of any such association because this hypothesis has yet to be tested. Retrospective analysis of cross-sectional national databases with limited potential for referral bias. National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, 2005-2010. Univariate, multivariate, stratified, and subgroup analyses were performed as defined a priori. The primary outcomes were OME, ETD, or TMR; the primary predictor variable was allergic rhinitis, with age evaluated as an effect modifier. Data representing 1,491,045,375 pediatric visits were examined and demonstrated that age was an effect modifier of the assessed association. More specifically, in children 6 years of age or older, the presence of allergic rhinitis significantly increased the odds of OME, ETD, or TMR (odds ratio [OR] 4.20; 95% confidence interval [CI] 2.17, 8.09; P < 0.001), whereas in children less than 6 years of age there was no significant association (OR 1.13; 95% CI 0.53, 2.46; P = 0.745). Age is an effect modifier of the association between allergic rhinitis and OME; a significant relationship is observed in children 6 years of age and older, whereas there is no significant association in younger children. 2c.

Objective Allergic rhinitis imposes a significant health and economic burden both on individuals and the healthcare system. Second-generation prescription antihistamines, levocetirizine, fexofenadine, and desloratadine, and the leukotriene receptor antagonist, montelukast, differ in their ability to relieve common rhinitis symptoms. The purpose of this study was to compare the cost-effectiveness of prescription agents based on their effectiveness in relieving nasal symptoms. Methods Effectiveness was measured as the composite of nasal symptoms, including congestion, rhinorrhea, and sneezing, from clinical studies that compared each of the 4 comparators to placebo. Direct costs included prescription therapy and rhinitis-related physician office visits. Physician office visit costs were collected from an analysis of the PharMetrics insurance claims database. Sensitivity analyses were conducted using a Monte Carlo simulation to assess the robustness of the average and incremental cost-effectiveness ratios. Results The cost per clinically significant improvement of nasal symptoms for levocetirizine was less than for the other model comparator agents. The incremental cost-effectiveness ratio for levocetirizine dominated montelukast and desloratadine and was lower than either branded or generic fexofenadine. Conclusion Levocetirizine is a cost-effective therapy for the relief of nasal symptoms of allergic rhinitis. PMID:25126257

Although quality of life studies suggest that allergic rhinitis has a substantial impact on work impairment, national survey estimates of the magnitude of this impairment have varied widely. Retrospective recall bias is likely to be a major cause of this variability. This study used a nationally representative daily diary sample to obtain prospective data that improve on previous estimates of the work impairment because of allergic rhinitis. The MacArthur Foundation National Survey of Daily Experience is a daily diary survey that included a nationally representative subsample of 739 employed people, each of whom provided daily reports on work performance for 1 randomly assigned week of the calendar year. National Allergy Bureau monitoring station data were merged with the survey data to study the association of time-space variation in pollen/mold exposure with impaired daily work quality and quantity. National Allergy Bureau pollen/mold counts are significantly related to work impairments only among respondents with self-reported allergic rhinitis. The average estimated monthly salary-equivalent work impairment costs associated with pollen/mold exposure for each allergy sufferer is between $109 and $156, with an annualized national projection of between $5.4 billion and $7.7 billion. The extent to which these costs can be recovered by increasing the proportion of allergy sufferers who are successfully treated remains unknown and can only be evaluated definitively in effectiveness trials.

Sublingual immunotherapy in patients with allergic rhinitis sensitised to house dust mites is safe, but its efficacy is controversial and sublingual immunotherapy with Blomia tropicalis has not yet been studied. This study sought to evaluate the efficacy of sublingual immunotherapy with house dust mite extract in children and adults with house dust mite allergic rhinitis over a period of two years. A prospective observational study was conducted of children and adults diagnosed with house dust mite allergic rhinitis who were treated with sublingual immunotherapy from 2008 to 2012. Total Nasal Symptom Scores, Mini Rhinoconjunctivitis Quality of Life scores and medication usage scores were assessed prospectively. Thirty-nine patients, comprising 24 children and 15 adults, were studied. Total Nasal Symptom Scores and Mini Rhinoconjunctivitis Quality of Life scores dropped significantly at three months into therapy, and continued to improve. Medication usage scores improved at one year into immunotherapy. Sublingual immunotherapy with house dust mite extracts, including B tropicalis, is efficacious as a treatment for patients with house dust mite allergic rhinitis.

Ganoderma lucidum (GL), an oriental medical mushroom, has been used in Asia for the prevention and treatment of a variety of diseases. However, the effect of GL on allergic rhinitis has not been well defined. The current study describes the inhibitory effect of GL on the biphasic nasal blockage and nasal hyperresponsiveness induced by repeated antigen challenge in a guinea pig model of allergic rhinitis. Intranasally sensitized guinea pigs were repeatedly challenged by inhalation of Japanese cedar pollen once every week. Ganoderma lucidum was orally administered once daily for 8 weeks from the time before the first challenge. The treatment with GL dose-dependently inhibited the early and late phase nasal blockage at the fifth to ninth antigen challenges. Furthermore, nasal hyperresponsiveness to intranasally applied leukotriene D₄ on 2 days after the eighth antigen challenge was also inhibited by the treatment with GL. However, Cry j 1-specific IgE antibody production was not affected by the treatment. In conclusion, we demonstrated that the pollen-induced biphasic nasal blockage and nasal hyperresponsiveness were suppressed by the daily treatment with GL in the guinea pig model of allergic rhinitis. These results suggest that GL may be a useful therapeutic drug for treating patients with allergic rhinitis. Copyright © 2011 John Wiley & Sons, Ltd.

Safety update regarding intranasal corticosteroids for the treatment of allergic rhinitis.

Blaiss, Michael S

2011-01-01

Intranasal corticosteroids (INSs) are the most efficacious medication for the treatment of allergic rhinitis. In 2006, the Joint Task Force of the American College of Allergy, Asthma, and Immunology, and the American Academy of Allergy, Asthma, and Immunology, published a white paper on the potential over-the-counter switch of INS (Bielory L, Blaiss M, Fineman SM, et al. Concerns about intranasal corticosteroids for over-the-counter use: Position statement of the Joint Task Force for the American Academy of Allergy, Asthma and Immunology and the American College of Allergy, Asthma and Immunology. Ann Allergy Asthma Immunol 96:514-525, 2006). The concern of the paper was the safety of the use of these agents without oversight by a health care professional. The objective of this paper was to review published literature on the safety of INS since the publication of the task force white paper. Recent studies, which evaluated topical and systemic adverse events associated with ciclesonide (CIC), fluticasone furoate (FF), mometasone furoate (MF), triamcinolone acetonide, fluticasone propionate, budesonide, and beclomethasone dipropionate were summarized. In general, no significant topical or systemic complications were observed in these studies, although none were >1 year in duration. The newer formulations of topical corticosteroids for allergic rhinitis, such as CIC, FF, and MF, which have less systemic bioavailability, may be safer for long-term use. New studies continue to add to the reassurance of the safety of INSs in the treatment of allergic rhinitis but still do not answer the question if these agents are appropriate for long-term use without oversight by a health care professional.

Nasal mucus is the first-line defense barrier against (aero-) allergens. However, its proteome and function have not been clearly investigated. The role of nasal mucus in the pathophysiology of allergic rhinitis was investigated by analyzing its proteome in patients with allergic rhinitis (n = 29) and healthy control subjects (n = 29). Nasal mucus was collected with a suction device, tryptically digested, and analyzed by using liquid chromatography-tandem mass spectrometry. Proteins were identified by searching the SwissProt database and annotated by collecting gene ontology data from databases and existing literature. Gene enrichment analysis was performed by using Cytoscape/BINGO software tools. Proteins were quantified with spectral counting, and selected proteins were confirmed by means of Western blotting. In total, 267 proteins were identified, with 20 (7.5%) found exclusively in patients with allergic rhinitis and 25 (9.5%) found exclusively in healthy control subjects. Five proteins were found to be significantly upregulated in patients with allergic rhinitis (apolipoprotein A-2 [APOA2], 9.7-fold; α2-macroglobulin [A2M], 4.5-fold; apolipoprotein A-1 [APOA1], 3.2-fold; α1-antitrypsin [SERPINA1], 2.5-fold; and complement C3 [C3], 2.3-fold) and 5 were found to be downregulated (antileukoproteinase [SLPI], 0.6-fold; WAP 4-disulfide core domain protein [WFDC2], 0.5-fold; haptoglobin [HP], 0.7-fold; IgJ chain [IGJ], 0.7-fold; and Ig hc V-III region BRO, 0.8-fold) compared with levels seen in healthy control subjects. The allergic rhinitis mucus proteome shows an enhanced immune response in which apolipoproteins might play an important role. Furthermore, an imbalance between cysteine proteases and antiproteases could be seen, which negatively affects epithelial integrity on exposure to pollen protease activity. This reflects the important role of mucus as the first-line defense barrier against allergens. Copyright © 2013 American Academy of Allergy, Asthma

Effects of a Spirulina-based dietary supplement on cytokine production from allergic rhinitis patients.

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.

Although the prevalence of asthma and allergic rhinitis has been increasing in tropical regions, little is known about the allergenicity of pollens from tropical plant families or the importance of ongoing environmental changes. We investigated associations between daily average pollen counts of several tropical plant families and sales of medications for the treatment of allergic rhinitis in Darwin, Australia-a tropical setting in which grass abundance has increased due to increased fire frequencies and the introduction of African pasture grasses. Daily pollen counts with detailed identification of plant species were undertaken in conjunction with a weekly survey of flowering plant species from April 2004 to November 2005. Five pharmacies provided daily sales data of selected medications commonly used to treat allergic rhinitis. We used generalized linear modeling to examine outcomes. All analyses accounted for the potential confounding effects of time trends, holidays, respiratory viral illnesses, meteorological conditions, and air pollution. The peak total pollen count was 94 grains/m(3). Despite the low levels of Poaceae (grass) pollen (maximum daily count, 24 grains/m(3)), there was a clear association with daily sales of anti-allergic medications greatest at a lag of 1 day. Sales increased by 5% with an interquartile range rise (3 grain/m(3)) in Poaceae pollen (5.07%, 95%CI 1.04%, 9.25%). No associations were observed with pollen from other plant families. Although further testing is required, we suggest that an overlooked aspect of the "grass-fire cycle" that is degrading many tropical landscapes, could be an increase in the prevalence of allergic rhinitis.

Little is known about exposure to mouse allergen (Mus m 1) and allergic rhinitis (AR). To evaluate the association between mouse allergen exposure and AR in children. We examined the relation between mouse allergen level in house dust and AR in 511 children aged 6 to 14 years in San Juan, Puerto Rico. Study participants were chosen from randomly selected households using a multistage probability sample design. The study protocol included questionnaires, allergy skin testing, and collection of blood and dust samples. AR was defined as current rhinitis symptoms and skin test reactivity to at least one allergen. In the multivariate analyses, mouse allergen level was associated with a 25% decreased odds of AR in participating children (95% confidence interval, 0.62-0.92). Although endotoxin and mouse allergen levels were significantly correlated (r = 0.184, P < .001), the observed inverse association between Mus m 1 and AR was not explained by levels of endotoxin or other markers of microbial or fungal exposure (peptidoglycan and glucan). Mouse allergen exposure is associated with decreased odds of AR in Puerto Rican school-aged children. Copyright © 2014 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc.

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

Some alternative products instead of immunotherapy are used in patients with allergic rhinitis (AR). In this paper, alternative products to treat allergic rhinitis and alternative routes for allergy immunotherapy are reviewed. Alternative products and methods used instead of immunotherapy are tea therapy, acupuncture, Nigella sativa, cinnamon bark, Spanish needle, acerola, capsaicin (Capsicum annum), allergen-absorbing ointment, and cellulose powder. N. sativa has been used in AR treatment due to its anti-inflammatory effects. N. sativa oil also inhibits the cyclooxygenase and 5-lipoxygenase pathways of arachidonic acid metabolism. The beneficial effects of N. sativa seed supplementation on the symptoms of AR may be due to its antihistaminic properties. To improve the efficacy of immunotherapy, some measures are taken regarding known immunotherapy applications and alternative routes of intralymphatic immunotherapy and epicutaneous immunotherapy are used. There are alternative routes and products to improve the efficacy of immunotherapy.

study for venom allergy which, despite being based largely on expert opinion and plausible assumptions, suggested that AIT for bee and wasp venom allergy is only likely to be cost-effective for very high-risk groups who may be exposed to multiple exposures to venom/year (eg bee keepers). We found no eligible studies investigating the cost-effectiveness of AIT for food allergy. Overall, the evidence to support the cost-effectiveness of AIT is limited and of low methodological quality, but suggests that AIT may be cost-effective for people with allergic rhinitis with or without asthma and in high-risk subgroups for venom allergy. We were unable to draw any conclusions on the cost-effectiveness of AIT for food allergy. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

Endonasal phototherapy with Rhinolight for the treatment of allergic rhinitis.

PubMed

Brehmer, Detlef

2010-01-01

Allergic rhinitis, although not life threatening, significantly affects the quality of the patient's daily life. The three major steps in the treatment of the condition are avoidance of allergens, treatment of symptoms (in particular, antihistaminics and topical nasal corticosteroids) and specific immunotherapy. Avoidance of the allergen is usually not possible and symptom relief is often limited, despite the availability of a number of pharmacological options. Specific immunotherapy demands a high level of cooperation on the part of the patient for at least 3 years. Endonasal phototherapy with the Rhinolight device (Rhinolight Ltd, Szeged, Hungary) for the treatment of immunoglobulin E-mediated allergic rhinitis is a new option that utilizes the immunosuppressive effects of UV radiation. The method directs a combination of UV-B (5%), UV-A (25%) and visible light (70%) into the nasal cavity, and its effectiveness has been demonstrated in one double-blind, placebo-controlled study. The results of additional studies have been presented at various medical conferences and in abstracts. Reports in the literature confirm that phototherapy is a well-established and successful treatment of atopic dermatitis and other skin diseases.

Allergic rhinitis (AR) remains a significant pediatric health problem because of the burden of uncontrolled symptoms on daily activities and on general well being. to assess the impact of AR on health-related quality of life (HRQL) of children and adolescents using a generic instrument, the Child Health Questionnaire (CHQ - PF50). Between January and November 2004, parents or caregivers of 23 children and adolescents with AR without comorbidities and with positive prick tests for at least one air allergen were invited to participate of a cross-sectional study and asked to answer the self-administered CHQ-PF50. The scores were compared to those of healthy children and adolescents. Patient scores were lower (p<0.05) than healthy subsets in both the physical and psychosocial summaries and in most of the CHQ-PF50 scales (p<0,05), except for the 'change in health' scale. The size effect was higher in the physical score compared to the psychosocial summary score. allergic rhinitis has a global negative impact on the HRQL of children and adolescents, with major repercussions in physical function; AR also negatively affects family relations.

To examine the impact of healthcare professional versus patient goal setting for the self-management of intermittent allergic rhinitis (AR) on symptom severity and quality of life. This was a 6 week, parallel group study. Group A participants, with pharmacist facilitation, nominated personally relevant goals and strategies relating to their AR. Group B participants had their goals and strategies set by the pharmacist. The main outcome measures used included perceived symptom severity and quality of life. In addition, goals and strategies data from participants of both groups were collected and analysed. Both groups demonstrated significant improvements in symptom severity and quality of life scores however Group B symptom severity scores improved more. Group B set a greater number of goals and strategies which were better structured and more task specific. This is the first study to investigate the impact of goal setting on patient behaviour in a chronic yet episodic illness. Our results suggest that self-management goals set by the healthcare professional which are clinically indicated but tailored to the patient's nominated symptoms yields better outcomes than goals nominated by the patient. A brief, structured intervention, tailored to patient symptoms, can enhance self-management of intermittent allergic rhinitis.

Rhinitis is a very common disorder caused by inflammation or irritation of nasal mucosa. Dominant symptoms are nasal obstruction; however, in some patients, runny nose, excessive sneezing or nasal itch may be the most bothersome symptoms. The most common causes of nasal inflammation are viral infections and allergic response to airborne allergens. Response to irritants may cause similar symptoms, although signs of inflammation may not always be present. Viral rhinitis is lasting up to 10 days and it is part of the common cold syndrome. In short-lived rhinitis, lasting for 7 to 10 days, sometimes it is not easy to differentiate between the potential causes of the disorder, if general symptoms of infection like fever and malaise are not present. In long-living rhinitis, it is important to differentiate between infectious, allergic, non-allergic non-infectious rhinitis, and chronic rhinosinusitis. Itch and ocular symptoms are more common in allergic rhinitis, while other symptoms like nasal obstruction, rhinorrhea and sneezing may affect patients with allergic and non-allergic rhinitis. Patients with allergic rhinitis often have symptoms after exposure to irritants, temperature and humidity changes, like patients with non-allergic rhinitis, and such exposure may sometimes cause more severe symptoms than exposure to allergens. Sensitivity to a non-specific trigger is usually called non-specific nasal hyperreactivity. Allergic rhinitis occurs due to immunoglobulin E (IgE) interaction with allergen in contact with nasal mucosa in a sensitized patient. Sensitization to certain airborne allergen, like pollens, dust, molds, animal dander, etc. usually occurs in families with allergy background, which is helpful in making diagnosis in patients who have rhinitis in a certain period of the year, or aggravation of nasal symptoms occurs in the environment typical of certain allergen. The diagnosis is clinically confirmed by proving sensitivity to certain allergen on skin prick

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. 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. 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. 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.

The present document is based on a consensus reached by a panel of experts from Chinese Society of Allergy (CSA) and Chinese Allergic Rhinitis Collaborative Research Group (C2AR2G). Allergen immunotherapy (AIT), has increasingly been used as a treatment for allergic rhinitis (AR) globally, as it has been shown to provide a long-term effect in improving nasal and ocular symptoms, reducing medication need, and improving quality of life. AIT is currently the only curative intervention that can potentially modify the immune system in individuals suffering from AR and prevent the development of new sensitization and the progression of disease from AR to asthma. Although the use of AIT is becoming more acceptable in China, to date no AR immunotherapy guideline from China is available for use by the international community. This document has thus been produced and covers the main aspects of AIT undertaken in China; including selection of patients for AIT, the allergen extracts available on the Chinese market, schedules and doses of allergen employed in different routes of AIT, assessment of effect and safety, patients’ administration and follow-up, and management of adverse reactions. The Chinese guideline for AR immunotherapy will thus serve as a reference point by doctors, healthcare professionals and organizations involved in the AIT of AR in China. Moreover, this guideline will serve as a source of information for the international community on AIT treatment strategies employed in China. PMID:29268533

Epidemiological studies show female predominance in the prevalence of non- allergic rhinitis (NAR) and local allergic rhinitis (LAR). Experimental studies show female patients with allergic rhinitis (AR) demonstrate higher levels of sensitivity to irritants and airway hyperresponsiveness than males. Bronchial asthma shows female predominance in post-puberty patients, and gender interaction with severe asthma endotypes. Fibromyalgia, chronic fatigue syndrome, migraine and chronic cough, syndromes, which are commonly related to neurokinin substance P (SP) in the literature, also show strong female predominance. Studies have demonstrated that sex hormones, primarily oestrogens, affect mast cell activation. Mast cell proteases can amplify neurogenic inflammatory responses including the release of SP. Based on human epidemiological data and animal experimental data we hypothesized that female patients have different interaction between mast cell activation and neurogenic inflammation, i.e. substance P release, resulting in a different nasal symptom profile. To test the hypothesis we performed allergen and non-specific nasal challenges in patients with seasonal allergic rhinitis (SAR) out of season and looked for gender differences in subjective and objective responses. The interaction between subjective and objective reactivity was evaluated through the comparison of subjective symptom scores, concentrations of neurokinin substance P (SP) and cellular markers in nasal lavages after low doses of nasal allergen challenges. Female allergic subjects tended to have higher substance P (SP) concentrations both before and after non-specific challenges. The difference between post-allergen and post - hypertonic saline (HTS) challenge was highly significant in female patients (p = 0.001), while insignificant in male subjects (p = 0.14). Female patients had significantly stronger burning sensation after HTS challenge than male. These data indicate difference in the

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.

The available allergic rhinitis (AR) literature continues to grow. Critical evaluation and understanding of this literature is important to appropriately utilize this knowledge in the care of AR patients. The International Consensus statement on Allergy and Rhinology: Allergic Rhinitis (ICAR:AR) has been produced as a multidisciplinary international effort. This Executive Summary highlights and summarizes the findings of the comprehensive ICAR:AR document. The ICAR:AR document was produced using previously described methodology. Specific topics were developed relating to AR. Each topic was assigned a literature review, evidence-based review (EBR), or evidence-based review with recommendations (EBRR) format as dictated by available evidence and purpose within the ICAR:AR document. Following iterative reviews of each topic, the ICAR:AR document was synthesized and reviewed by all authors for consensus. Over 100 individual topics related to AR diagnosis, pathophysiology, epidemiology, disease burden, risk factors, allergy testing modalities, treatment, and other conditions/comorbidities associated with AR were addressed in the comprehensive ICAR:AR document. Herein, the Executive Summary provides a synopsis of these findings. In the ICAR:AR critical review of the literature, several strengths were identified. In addition, significant knowledge gaps exist in the AR literature where current practice is not based on the best quality evidence; these should be seen as opportunities for additional research. The ICAR:AR document evaluates the strengths and weaknesses of the AR literature. This Executive Summary condenses these findings into a short summary. The reader is also encouraged to consult the comprehensive ICAR:AR document for a thorough description of this work. © 2018 ARS-AAOA, LLC.

In this study, we evaluated the therapeutic efficacy of selected probiotics in a mouse model of birch pollen (BP)-induced allergic rhinitis. Oral administration of Lactobacillus plantarum CJLP133 and CJLP243 ameliorated the symptoms of BP-induced allergic rhinitis by reducing airway hyperresponsiveness, and both the histological scores and the number of infiltrated cells in the nasal cavities and lungs. Compared with those from vehicle-treated mice, bronchoalveolar lavage fluid and draining lymph node samples from CJLP133 and CJLP243-administrated mice showed diminished numbers of immune cells, increased secretion of a Th1-type cytokine (IFN-γ) and decreased production of Th2-type cytokines (IL-4, IL-5 and IL-13). Consistent with these results, levels of IL-4, IL-5, IL-13, serum IgE and BP-specific serum IgG1 were decreased, whereas secretion of IFN-γ and BP-specific serum IgG2a was augmented upon administration of CJLP133 and CJLP243 in mice. Oral administration of L. plantarum CJLP133 and CJLP243 alleviates symptoms of BP-induced allergic rhinitis in mice by recovering Th1/Th2 balance via enhancement of the Th1-type immune response. Lactobacillus plantarum CJLP133 and CJLP243 have therapeutic effects on BP-induced allergic rhinitis in an animal model. © 2017 The Society for Applied Microbiology.

The purpose of this study was to determine which aeroallergens were prevalent in patients with allergic rhinitis in Beijing. A total of 554 cases (female: 212, male: 342, aged between 4-69 years) who were diagnosed with allergic rhinitis by history and clinical presentation, underwent a skin prick test with 20 standardized aeroallergens, and the important sensitizing allergens were assessed. The samples were stratified on two age groups: 4-18-year-olds (children group, n = 81) and 19-60-year-olds (adults group, n = 401). Difference of SPT responses of the two groups was investigated. The percent of patients with positive skin tests were follow:D. farinae (64.6%), D. pteronyssinus (64.3%), Flowers pollen (28.7%), Herbs (26.5%), Lamb's Quarters (13.7%) ,Tree II (13.5%), Giant Ragweed (12.5%). Tree I (12.5%) There were significantly higher sensitivity to dust mite among children group compared to adults group (P < 0.01). The study shows that the dust mite, Flowers pollen and Herbs are the most important three aeroallergens in Beijing region.

The common cold and allergic rhinitis constitute a global health problem that affects social life, sleep, school and work performance and is likely to impose a substantial economic burden on society because of absence from work and reduced working capacity. This study assesses the loss of productivity as a result of both allergic rhinitis and the common cold in the Swedish working population. Four thousand questionnaires were sent to a randomized adult population, aged 18-65 years, in Sweden, stratified by gender and area of residence (metropolitan area vs rest of the country). The human capital approach was used to assign monetary value to lost productivity in terms of absenteeism (absence from work), presenteeism (reduced working capacity while at work) and caregiver absenteeism (absence from work to take care of a sick child). Thousand two hundred and thirteen individuals responded, response rate 32%. The mean productivity loss was estimated at 5.1 days or euro 653 per worker and year, yielding a total productivity loss in Sweden of euro 2.7 billion a year. Of the total costs, absenteeism (44%) was the dominant factor, followed by presenteeism (37%) and caregiver absenteeism (19%). Poisson regression analyses revealed that women, people in the 18-29 year age group, and respondents with 'doctor-diagnosed asthma' reported more lost days than the rest of the group. In Sweden, the cost of rhinitis is euro 2.7 billion a year in terms of lost productivity. A reduction in lost productivity of 1 day per individual and year would potentially save euro 528 million.

Allergic rhinitis is one of several inflammatory diseases affecting the nasal mucosa. Cellular inflammation of nasal mucosa is a hallmark of this disease and is characterized by the accumulation of eosinophils and the release of various chemical messengers such as chemokines, cytokines, and histamine. This inflammation of the nose leads to nasal congestion and a reduction in sleep quality, resulting in daytime somnolence. Drugs that significantly reduce the symptoms of nasal congestion also may help in alleviating sleep-related symptoms of allergic rhinitis. Pseudoephedrine is a sympathomimetic amine that is indicated for treatment of nasal congestion associated with allergic rhinitis. Despite relieving nasal congestion, we speculated that, because of pseudoephedrine's well-known stimulant profile, sleep would not be improved. Fourteen subjects who met the inclusion criteria were enrolled into a double-blind, placebo-controlled, randomized study to either pseudoephedrine or placebo once per day in the morning, using the traditional crossover design. Skin testing test was performed to ensure a positive response to a relevant perennial allergen and a negative response to a seasonal allergen. Several questionnaires were used to evaluate the patients' sleep-related symptoms, allergic rhinitis symptoms, and quality of life. Our results showed that pseudoephedrine did not have a positive or negative effect on quality of sleep, daytime sleepiness, or daytime fatigue as compared with placebo. Pseudoephedrine did show a statistical significance in improving stuffy nose (P = .0172). With respect to quality of life, pseudoephedrine led to a statistically significant decrease in intimate relationships and sexual activity as compared with the placebo group (P = .0310). Our research suggests that sleep quality is not significantly affected by pseudoephedrine. As expected, congestion is reduced, but side effects such as a decline of intimate relationships and sexual activity may

(1) Twelve rabbits were divided into two groups: group A (sensitized) and group B (control). Four rabbits were killed respectively in one and four weeks in group A after being sensitized . Two rabbits were killed respectively at the same time in group B. Their nasal mucosa were collected for detecting substance P (SP) and calcitonin gene-related peptide (CGRP) by immunohistochemistry. (2) Twenty-four rabbits were divided into two groups: group A (sphenopalatine nerve was cut), group B (sympathetic nerve was cut). Four rabbits were killed respectively in one, two, and four weeks in group A and B. Their nasal mucosa were collected for immunohistochemistry examination. (1) SP and CGRP were apparently higher in allergic rabbits than non-allergic ones. (2) SP and CGRP decreased apparently in one and two weeks in group A and appeared no difference in four weeks. There were no apparently difference in group B among four weeks. SP and CGRP are correlative with the occurring and developing of all allergic rhinitis.

The ARIA (Allergic Rhinitis and its Impact on Asthma) guidelines development group examined the properties of oral H(1)-antihistamines and made proposals about an 'optimal' drug. Several criteria should be met by oral H(1)-antihistamines in terms of their pharmacological, and clinical efficacy and safety profiles. Bilastine, a new H(1)-antihistamine, has been approved in 28 European countries for the symptomatic treatment of allergic rhinoconjunctivitis and urticaria in adults and children older than 12 years. To determine its potential place in therapy in the treatment of allergic rhinitis, this manuscript examines whether bilastine meets the criteria defined in the European Academy of Allergy and Clinical Immunology (EAACI)/ARIA proposals for oral H(1)-antihistamines. The optimal properties of oral H(1)-antihistamines and current ARIA recommendations for their use in allergic rhinitis are presented, as well as relevant pharmacological and clinical data for bilastine obtained from the published literature that specifically address the defined criteria. Bilastine is a potent inhibitor of the histamine H(1) receptor. Data from preclinical studies have confirmed its selectivity for the histamine H(1) receptor over other receptors, and demonstrated antihistaminic properties in vitro and in vivo. Bilastine does not interfere with the cytochrome P450 system and is devoid of cardiac side effects. Studies in healthy volunteers and patients have shown that bilastine does not affect driving ability, cardiac conduction or alertness. In large pivotal randomized, placebo-controlled trials (RCTs), bilastine had a favourable safety profile. Bilastine 20 mg once daily improved all nasal and ocular symptoms of allergic rhinitis with greater efficacy than placebo and comparable to that of cetirizine and desloratadine. Moreover, bilastine was shown to improve quality of life, an important outcome of RCTs in allergic diseases. There were no significant changes in laboratory tests

Complementary and alternative medicine (CAM) is extensively used in patients with allergic diseases worldwide. The purpose of this study was to investigate the actual situation of CAM practice in the treatment of allergic rhinitis. We distributed questionnaires to otolaryngologists at 114 facilities in Japan. The subjects who participated in this study included children <16 years of age and adults ≥16 years of age diagnosed with allergic rhinitis by otolaryngologists. The survey was performed in the period from September 2007 to August 2009. Furthermore, we performed the same investigation out of the hospital setting, such as during general health examinations. All questionnaires were returned to Chiba University and analyzed. The proportions of patients who had ever experimented with CAM in the hospital survey were 7.1% (225/3170) and 19.2% (1416/7363) of children and adults, respectively. Approximately 36.2% of the adult patients thought that the treatments were effective. The main reasons for CAM use were safety, convenience and low price. However, the group who spent more than $1000 on CAM felt more dissatisfaction and anxiety related to treatment at the hospital. The situation of CAM practice was not consistent and was instead influenced by the backgrounds of the subjects. Many patients who receive CAM report feeling that the effects of treatment provided by hospitals are insufficient and have concerns about the side effects of such treatments. Information regarding standard treatments, as described in the guidelines, should become widely known and diffused, and strong communication with patients should be considered.

A reproducible standard for a graded allergen response in allergic rhinitis is lacking. The aim was to evaluate basophil allergen threshold sensitivity, CD-sens, as a diagnostic complement to nasal allergen challenge. Twenty-six patients with a history of allergic rhinitis due to grass pollen were intranasally challenged and nasal symptom score and peak nasal inspiratory flow (PNIF) changes were determined after 15 min. A 20% decrease in PNIF or a symptom score ≥2 were considered a positive test. A blood sample for CD-sens was drawn before each challenge. Eighteen patients were tested twice. CD-sens agreed with the positive or negative nasal symptom score in 22/26 and PNIF in 24/26 patients. After the second challenge, 14/18 patients had the same symptom, 17/18 the same PNIF, while all had identical CD-sens classification. CD-sens appears to be a reproducible test for diagnosis of allergic rhinitis with great advantages also for follow-up of disease development and treatment effects. Copyright © 2012 S.

Allergic rhinitis is an immunological disorder and an inflammatory response of nasal mucosal membranes. Allergic rhinitis, a state of hypersensitivity, occurs when the body overreacts to a substance such as pollens or dust. 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. Since inflammation is an integral mechanistic component of allergy, the present study aimed to determine the anti-inflammatory activity of Aller-7 in various in vivo models. The efficacy of Aller-7 was investigated in compound 48/80-induced paw edema both in Balb/c mice and Swiss Albino mice, carrageenan-induced paw edema in Wistar Albino rats and Freund's adjuvant-induced arthritis in Wistar Albino rats. The trypsin inhibitory activity of Aller-7 was also determined and compared with ovomucoid. At a dose of 250 mg/kg, Aller-7 demonstrated 62.55% inhibition against compound 48/80-induced paw edema in Balb/c mice, while under the same conditions prednisolone at an oral dose of 14 mg/kg exhibited 44.7% inhibition. Aller-7 significantly inhibited compound 48/80-induced paw edema at all three doses of 175, 225 or 275 mg/kg in Swiss Albino mice, while the most potent effect was observed at 225 mg/kg. Aller-7 (120 mg/kg, p.o.) demonstrated 31.3% inhibition against carrageenan-induced acute inflammation in Wistar Albino rats, while ibuprofen (50 mg/kg, p.o.) exerted 68.1% inhibition. Aller-7 also exhibited a dose-dependent (150-350 mg/kg) anti-inflammatory effect against Freund's adjuvant-induced arthritis in Wistar Albino rats and an approximately 63% inhibitory effect was observed at a dose of 350 mg/kg. The trypsin inhibitory activity of Aller-7 was determined, using ovomucoid as a positive control. Ovomucoid and Aller-7 demonstrated

nonasthmatic patients with allergic rhinitis often have bronchial hyperresponsiveness (BHR). Not only the presence but also the degree of atopy are important factors in BHR of patients with asthma. BHR is commonly evaluated by bronchial challenges using direct or indirect stimuli. to assess BHR to methacholine (direct) and to adenosine monophosphate (AMP) (indirect) in children with allergic rhinitis and to compare their relationships with the degree of atopy. methacholine and AMP challenges were performed in 88 children with allergic rhinitis, and a provocative concentration causing a 20% decrease in forced expiratory volume in 1 second (PC(20)) was calculated for each challenge. The degree of atopy was measured using serum total IgE levels, number of positive skin prick test results, and atopic scores (sum of graded wheal size). BHR to methacholine (PC(20) <8 mg/mL) and to AMP (PC(20) <200 mg/mL) was observed in 22 (25%) and 30 (34%) patients, respectively. No association was found between BHR to methacholine and any atopy parameter. In contrast, serum total IgE levels and atopic scores were higher in the group with BHR to AMP than in the group without BHR to AMP. Furthermore, a significant association was found between the degree of these 2 parameters and BHR to AMP (score for trend, P < .001 and P = .03, respectively). both BHR to methacholine and BHR to AMP were detected in a significant proportion of children with allergic rhinitis. The degree of atopy seems to be an important factor in BHR to AMP but not in BHR to methacholine.

Allergic rhinitis (AR) is the most common manifestation of atopic reaction to inhaled allergens. It is a chronic inflammatory disease which may first appear at any age, but the onset is usually during childhood or adolescence. Up to date there is no curative treatment for this disorder and most of the drugs that were used for treatment only can induce symptomatic relief and some of them have side effect and can cause withdrawal symptoms. To evaluate the therapeutic efficacy of the Nigella sativa (NS) extract as treatment approach for allergic rhinitis. A total of 68 patients with AR were included in the study, of them 19 patients were with mild symptoms, 28 patients were with moderate symptoms and 21 patients were with severe symptoms. Each group was subdivided into active and control subgroups. To prove that the patient's symptoms were allergic in nature, skin test was performed for all patients. Any individual with negative skin test was excluded. The individuals in the active group received N. sativa oil and the control group individuals received ordinary food oil in the form of nasal drops for 6 weeks. After the 6 weeks treatment course, 100% of the patients in the mild active group became symptoms free; while in moderate active group 68.7% became symptoms free and 25% were improved; while in severe active group 58.3% became symptoms free and 25% were improved. In addition, 92.1% of total patients in the active group demonstrated improvement in their symptoms or were symptoms free, while the corresponding value was 30.1% in the control group (P=0.000). At the end of 6 weeks of treatment with topical use, the improvement in tolerability of allergen exposure in active group became 55.2% which was significant (P=0.006) as compared with control group which was accounted for 20% at the same time. Topical application of black seed oil was effective in the treatment of allergic rhinitis, with minimal side effects.

This study was to investigate the association between dietary patterns and rhinitis in primary school children. 1,599 students without rhinitis at baseline survey were selected from a primary school children cohort. Information on food consumption, respiratory symptoms, and confounders was collected using questionnaires. Dietary patterns were defined using principal component analysis. Logistic regression was performed to calculate odds ratio (OR) with 95% confidence intervals (95% CI). The incidence of rhinitis during 12 months follow-up was 21.2%. Three patterns were extracted and labeled as pattern I, II and III. Dietary pattern II which had higher factor loadings of legumes, butter, nuts and potatoes was associated with an increased risk of rhinitis (OR: 1.34, 95% CI: 1.01–1.87) when the highest tertile of pattern score was compared to the lowest tertile, after adjusted for confounders. Besides, every 1-unit increase of score of pattern II was also associated with an increased risk of rhinitis (OR: 1.19, 95% CI: 1.05–1.35). Neither pattern I nor Pattern III was observed to be associated with risk of rhinitis. A diet with higher levels of consumption of legumes, butter, nuts and potatoes may increase the risk of allergic rhinitis in primary school children. PMID:28294150

Patients in Taiwan with allergic rhinitis seek not only Western medicine treatment but also Traditional Chinese Medicine treatment or integrated Chinese-Western medicine treatment. Various studies have conducted pairwise comparison on Traditional Chinese Medicine, Western medicine, and integrated Chinese-Western medicine treatments. However, none conducted simultaneous analysis of the three treatments. This study analyzed patients with allergic rhinitis receiving the three treatments to identify differences in demographic characteristic and medical use and thereby to determine drug use patterns of different treatments. The National Health Insurance Research Database was the data source, and included patients were those diagnosed with allergic rhinitis (International Classification of Diseases, Ninth Revision, Clinical Modification codes 470-478). Chi-square test and Tukey studentized range (honest significant difference) test were conducted to investigate the differences among the three treatments. Visit frequency for allergic rhinitis treatment was higher in female than male patients, regardless of treatment with Traditional Chinese Medicine, Western medicine, or integrated Chinese-Western medicine. Persons aged 0-19 years ranked the highest in proportion of visits for allergic rhinitis. Traditional Chinese Medicine treatment had more medical items per person-time and daily drug cost per person-time and had the lowest total expenditure per person-time. In contrast, Western medicine had the lowest daily drug cost per person-time and the highest total expenditure per person-time. The total expenditure per person-time, daily drug cost per person-time, and medical items per person-time of integrated Chinese-Western medicine treatment lay between those seen with Traditional Chinese Medicine and Western medicine treatments. Although only 6.82 % of patients with allergic rhinitis chose integrated Chinese-Western medicine treatment, the visit frequency per person-year of

Allergic rhinitis (AR) is considered to be a public health problem, therefore it is essential to test health education strategies such as nursing counseling (NC) aimed at population groups such as children with allergic rhinitis and their tutors. This study aimed to measure the health benefits of children with this disease for a year. Longitudinal, randomized, comparative study with a sample of 100 pediatric patients of both sexes, aged 6 to 12 years, with diagnosis of allergic rhinitis, with counseling (study group) and without counseling (control group). In both groups, an informed consent letter signed by both tutors was obtained, in addition to knowledge and assessment papers; the latter included a scale of symptomatology and Morisky Green (adherence to treatment). The children in the study group received intervention based on personalized education, didactic material, support of the multidisciplinary group if necessary (doctor, dermatologist and psychologist). The control group received usual care. In both groups, telephone follow-up was performed, which allowed the number of relapses to be identified in one year. The Wilcoxon rank-sum test (Mann-Whitney) was used to compare the results; the presence of relapses in the control group was statistically significant compared to the study group. It was found that the infant population that receives NC, has as a better benefit the control of the symptomatology and decrease of relapses per year. Copyright © 2017.

The aim of this study was to evaluate the efficacy and safety of a fixed-dose combination of montelukast and levocetirizine in patients with perennial allergic rhinitis with mild to moderate asthma compared with the efficacy and safety of montelukast alone. This study was a 4-week, randomized, multicenter, double-blind, Phase III trial. After a 1-week placebo run-in period, the subjects were randomized to receive montelukast (10mg/day, n = 112) or montelukast (10 mg/day)/levocetirizine (5 mg/day) (n = 116) treatment for 4 weeks. The primary efficacy end point was mean daytime nasal symptom score. Other efficacy end points included mean nighttime nasal symptom score, mean composite symptom score, overall assessment of allergic rhinitis by both subjects and physicians, forced expiratory volume in 1 second (FEV 1 ), forced vital capacity (FVC), FEV 1 /FVC, asthma control test score, and the frequency of rescue medication used during the treatment period. Of 333 patients screened for this study, 228 eligible patients were randomized to treatment. The mean (SD) age of patients was 43.32 (15.02) years, and two thirds of subjects were female (66.67%). The demographic characteristics were similar between the treatment groups. Compared with the montelukast group, the montelukast/levocetirizine group reported significant reductions in mean daytime nasal symptom score (least squares mean [SE] of combination vs montelukast, -0.98 [0.06] vs -0.81 [0.06]; P = 0.045). For all other allergic rhinitis efficacy end points, the montelukast/levocetirizine group showed greater improvement than the montelukast group.

Although specific nasal provocation is an objective diagnostic test for allergic rhinitis, it can also increase the lower airway responsiveness in asthmatic patients. Our goal was to determine the value and safety of specific nasal provocation test for the diagnosis of allergic rhinitis in mild persistent asthmatic patients under low-dose inhaled steroid therapy. The study was performed on 32 mild persistent, stable, mite-sensitive allergic asthmatics (group 1), 9 mild persistent nonallergic asthmatics (group 2) and 9 healthy non-smokers (group 3). Nasal symptoms were noted, paranasal sinus computerized tomography (PNCT) and rhinoscopic evaluations were performed. Cases with pathologic-anatomic changes in PNCT and rhinoscopy were excluded. Symptom scoring, flow-volume, peak expiratory flow (PEF), serum and nasal lavage eosinophil cationic protein (ECP) and nasal lavage eosinophil counts were performed before mite specific nasal provocation test and at the 0th, 4th and 24th hours following the test. No adverse effects were observed in all diagnostic procedures. Total diagnostic value of nasal symptoms were found to be at 92%, while being 70% for rhinoscopy and 88% for specific nasal provocation test respectively in the diagnosis of allergic rhinitis in group 1. Statistically significant differences were found between basal nasal lavage eosinophil values (p < 0.001) and ECP levels (p < 0.05) when group 1 was compared with both group 2 and group 3. In the remaining measured values between three groups, no statistically significant differences were found. Specific nasal provocation test is a safe method for mild house dust mite allergic asthma cases under low-dose inhaled steroid therapy, but history of rhinitis might be sufficient for the diagnosis of allergic rhinitis.

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

Allergic rhinitis is a high-prevalence disease that affects quality of life (QOL), sleep quality and productivity of patients. According to the ARIA initiative, it is classified as intermittent and persistent, the latter being the most troublesome. The aim of this randomized, open-label, 6-month, pilot study was to determine whether levocetirizine 5 mg administered continuously once daily in the morning was better than levocetirizine 5 mg on-demand in symptomatic subjects with persistent allergic rhinitis. Total and individual symptom scores were recorded in a diary card throughout the study. QOL, quality of sleep, nasal cytology, rate of drug intake, and safety were also assessed at pre-defined time-points. In all, adult patients (31 in each group) were enrolled, of whom 22 dropped out. Both treatment regimens considerably decreased the total and individual symptoms scores from baseline and achieved similar levels up to week 14. Continuous treatment was generally better than on-demand from week 15 onwards, reaching statistical significance from weeks 17 to 21 (from week 19 to 21 for nasal pruritus). Both regimens substantially improved QOL and sleep quality. Both treatments were well tolerated, although the on-demand group reported more adverse events. The present open label study in 62 patients indicates that levocetirizine 5 mg reliably controls persistent rhinitis over a period of 6 months, and shows a trend to be more effective in controlling the symptoms of rhinitis, improving QOL and decreasing nasal inflammation, when administered as long-term continuous therapy rather than as on-demand therapy.

Environmental control has been put forward as an integral part of the management of house dust mite (HDM) allergy in sensitized patients. To validate this statement allergic disorders involved in HDM allergy--allergic asthma, rhinitis and atopic eczema/dermatitis syndrome (AEDS)--should be taken together and studied in terms of the efficacy of environmental control. Because a generic quality of life questionnaire exceeds the border of disease, this may be used as major outcome parameter. To study the effects of bedding encasings in HDM allergic patients with asthma, rhinitis and AEDS. A total of 224 adult HDM allergic patients with rhinitis and/or asthma and/or dermatitis were randomly allocated impermeable or nonimpermeable encasings for mattress, pillow and duvet. Short form 36 (SF-36) was filled in at baseline and after 12 months. Lower physical (P = 0.01) and emotional (P < 0.001) sumscores were seen in females. Also, the presence of asthma resulted in lower physical sumscore (P = 0.01). However, no effect was seen of encasings on either sumscore. Bedding encasings do not improve quality of life in a mixed population of subjects with combinations with rhinitis, asthma and atopic dermatitis and sensitized to HDMs.

The efficacy of Lactobacillus paracasei NCC 2461 in modulating allergic rhinitis was previously evaluated in two exploratory clinical studies. Oral administration with NCC 2461 reduced specific subjective symptoms following nasal provocation tests with controlled grass pollen allergen concentrations. Our aim was to confirm the anti-allergic effect of NCC 2461 in grass pollen allergic subjects exposed to natural doses of allergens during the pollen season. A double-blind, randomized, placebo-controlled, parallel study was conducted with 131 grass pollen allergic subjects from May to July 2012 in concomitance with the pollen season in Berlin. NCC 2461 or placebo was administered daily for an 8-week period to adult subjects with clinical history of allergic rhinitis to grass pollen, positive skin prick test and IgE to grass pollen. During the 8 weeks, symptoms and quality of life questionnaires were filled out, and plasma was collected for IgE analysis at screening and at the end of the intervention. All subjects were included within a 5-day interval, ensuring exposure to similar air pollen counts for each individual during the trial period. The results obtained show that symptoms increased with pollen loads, confirming a natural exposure to the allergen and presence of pollen-induced allergic rhinitis in the subjects. However, no significant differences were observed in allergic rhinitis symptoms scores, quality of life, or specific IgE levels between subjects receiving NCC 2461 as compared to placebo administration. In contrast to previous findings, oral administration of NCC 2461 did not show a beneficial effect on allergic rhinitis in a field trial. The influence of study design, allergen exposure and intervention window on the efficacy of NCC 2461 in modulating respiratory allergy should be further evaluated.

Anxiety and psychological stress affect allergy-related immune function. How these relations influence the evaluations of patients with allergic rhinitis is unknown. To examine whether anxiety and stress exposure affect skin prick test (SPT) responses to common allergens for which patients with atopy showed no prior positive SPT response. Patients with allergic rhinitis, evidenced by clinical history and SPT results, were admitted twice to a hospital research unit for 4 hours. In a crossover design, SPT wheals were assessed before and after the Trier Social Stress Test and then the following morning; for comparison, SPT wheals were assessed before and after a laboratory session without a stressor. Analyses focused on wheal responses for common allergens that tested negative (wheal size <3 mm larger than saline) from SPTs performed at multiple baseline assessments. After the Trier Social Stress Test, more anxious patients with atopy had a higher incidence of positive SPT reactions to antigens that previously tested negative. Anxiety was unrelated to positive SPT incidence under nonstressful conditions. Based on clinical symptom reports, newly positive SPT reactions after the stressor were apparently corrections of previously false-negative SPT reactions. The SPT wheal responses for allergens previously testing negative were enhanced after a stressor. Histamine (positive control) or saline (negative control) SPT responses were not affected. A laboratory stressor affected allergen SPT responses in more anxious patients with allergic rhinitis. In addition to clinical history, assessment of anxiety and current stress at the time of the SPT may provide valuable information about a patient's allergic status and aid in clinical decision making.

Rhinitis and asthma: evidence for respiratory system integration.

PubMed

Togias, Alkis

2003-06-01

The vast majority of patients with asthma have rhinitis, and rhinitis is a major independent risk factor for asthma in cross-sectional and longitudinal studies. The relationships between rhinitis and asthma can be viewed under the concept that the 2 conditions are manifestations of one syndrome, the chronic allergic respiratory syndrome, in 2 parts of the respiratory tract. At the low end of the syndrome's severity spectrum, rhinitis appears to be the sole manifestation, although pathologic abnormalities in the lower airways are already present. At the higher end, rhinitis is worse, and the lower airways disease becomes clinically evident. Once manifested, the 2 conditions track in parallel in terms of severity. This parallel relationship is influenced by many interactions between the nasal and the lower airways: some interactions stem from the fact that the nasal passages play a major homeostatic role by conditioning inhaled air, but perhaps even more important is the bidirectional interaction that results from the systemic inflammation that is produced after local allergic reactions. Successful management of the chronic allergic respiratory syndrome requires an integrated view of the airways and an understanding of their interactions.

Allergic rhinitis (AR) and asthma represent global health problems for all age groups. Asthma and rhinitis frequently coexist in the same subjects. Allergic Rhinitis and its Impact on Asthma (ARIA) was initiated during a World Health Organization workshop in 1999 (published in 2001). ARIA has reclassified AR as mild/moderate-severe and intermittent/persistent. This classification closely reflects patients' needs and underlines the close relationship between rhinitis and asthma. Patients, clinicians, and other health care professionals are confronted with various treatment choices for the management of AR. This contributes to considerable variation in clinical practice, and worldwide, patients, clinicians, and other health care professionals are faced with uncertainty about the relative merits and downsides of the various treatment options. In its 2010 Revision, ARIA developed clinical practice guidelines for the management of AR and asthma comorbidities based on the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) system. ARIA is disseminated and implemented in more than 50 countries of the world. Ten years after the publication of the ARIA World Health Organization workshop report, it is important to make a summary of its achievements and identify the still unmet clinical, research, and implementation needs to strengthen the 2011 European Union Priority on allergy and asthma in children.

Several studies conducted during the past two decades suggested increasing trend of childhood allergic diseases in China. However, few studies have provided detailed description of geographic variation and explored risk factors of these diseases. This study investigated the pattern and risk factors of asthma, allergic rhinitis and eczema in eight metropolitan cities in China. We conducted a cross-sectional survey during November-December 2005 in eight metropolitan cities in China. A total of 23791 children aged 6-13 years participated in this survey. Questions from the standard questionnaire of the International Study of Asthma and Allergies in Children (ISAAC) were used to examine the pattern of current asthma, allergic rhinitis and eczema. Logistic regression analyses were performed to assess the risk factors for childhood allergies. The average prevalence of childhood asthma, allergic rhinitis and eczema across the eight cities was 3.3% (95% Confidence interval (CI): 3.1%, 3.6%), 9.8% (95% CI: 9.4%, 10.2%) and 5.5% (95% CI: 5.2%, 5.8%), respectively. Factors related to lifestyle, mental health and socio-economic status were found to be associated with the prevalence of childhood allergies. These risk factors were unevenly distributed across cities and disproportionately affected the local prevalence. There was apparent geographic variation of childhood allergies in China. Socio-environmental factors had strong impacts on the prevalence of childhood allergies; but these impacts differed across regions. Thus public health policies should specifically target at the local risk factors for each individual area.

The antiallergic action of 2-[2-[4-(diphenylmethyl)-1-piperadinyl] ethoxy] benzoic acid maleate (ZCR-2060) was investigated on allergic cutaneous reactions and nasal vascular permeability in mice and rats. ZCR-2060 markedly inhibited immediate allergic cutaneous reactions, including passive cutaneous anaphylaxis (PCA) in rats and mice; histamine-, compound 48/80- and calcium ionophore A 23187-induced cutaneous reactions in rats; and biphasic skin reactions mediated by monoclonal IgE antibody and epicutaneous challenge with antigen in mice, but did not affect 5-hydroxytryptamine-induced cutaneous reaction in rats. The antigen-induced nasal vascular permeability increase in actively and passively sensitized rats and histamine-induced nasal vascular permeability increase in rats (allergic rhinitis model) were clearly inhibited in a dose-dependent fashion by ZCR-2060. Moreover, ZCR-2060 significantly inhibited antigen-induced anaphylactic histamine release from rat peritoneal mast cells and carrageenin-induced paw edema in rats. These results suggest that ZCR-2060 has antiallergic effects on allergic cutaneous reactions and experimental rhinitis, probably due to histamine H1-receptor blockage and the inhibition of histamine release.

Low-grade inflammation conditions, e.g., type 2 diabetes, have been shown to be associated with an increased risk of rheumatoid arthritis (RA). However, the association between other chronic inflammatory conditions, e.g., asthma, allergic rhinitis, and atopic dermatitis, is still unclear. To investigate the risk of RA in patients with allergic diseases, including asthma, allergic rhinitis, and atopic dermatitis, by using a nationwide health claims database. The Taiwan National Health Insurance Research Database was used to assemble a cohort of 170,570 patients ages 20 years old and older diagnosed with allergic diseases, including asthma, allergic rhinitis, or atopic dermatitis. A comparison cohort of 170,238 patients was constructed from the same data base, with frequency matching for sex, 10-year age group, and year of insurance enrollment. Cox proportional hazards regression analyses were conducted to assess the association between the allergic diseases and incident RA. Asthma (adjusted hazard ratio [AHR] 1.67, [95% confidence interval {CI}], 1.32-2.62) and allergic rhinitis (AHR 1.62 [95% CI, 1.33-1.98]) were significantly associated with the incident RA. These associations remained significant even after excluding patients who had concurrent diagnoses of asthma and allergic rhinitis. Patients with more than one allergic disease had an increased risk of developing RA (AHR 1.98 [95% CI, 1.50-2.62]). Subgroup analysis further indicated that middle-aged and elderly female patients with more than one allergic disease exhibited a high risk of developing RA. Significant associations between common allergic diseases and incident RA was found in this population-based cohort study. Our findings provided support to the hypothesis that allergic diseases and RA might share a similar underlying etiologic pathway related to chronic inflammatory responses.

To analyse the relationship between obesity and overweight and the prevalence of allergic diseases and sensitization, and the impact of gender and place of residence. Questionnaire based on those used in ISAAC (International Study of Asthma and Allergies in Childhood) and ECRHS (European Community Respiratory Health Survey). Our study involved populations of the eight largest cities and one rural region in Poland (each with over 150,000 inhabitants). The study included 18,617 participants (24·2% aged 6-7 years, 25·4% aged 13-14 years, 50·4% adults aged 20-44 years) in eight cities and one rural area. The out-patient study involved 4783 patients (25·7%); we performed skin prick testing with fifteen aeroallergens. Overweight was found in 16·13% of participants (9·11% of 6-7-year-olds, 4·90% of 13-14-year-olds and 25·61% of adults), obesity in 6·41% (7·16%, 2·45% and 8·36%, respectively). In adults, overweight (OR=1·34) and obesity (OR=1·80) increased the prevalence of asthma, especially in women (OR=1·53, OR=2·01). Among 13-14-year-olds the prevalence was higher only in the obese (OR=1·76). Overweight (OR=1·99) and obesity (OR=2·17) affected the incidence of doctor-diagnosed asthma in 6-7-year-olds. Overweight (OR=0·81) and obesity (OR=0·76) reduced the prevalence of allergic rhinitis in men. There was no relationship between BMI and asthma in people from rural areas. Obesity and overweight did not affect the frequency of sensitization to aeroallergens. Overweight and obesity increased the prevalence of symptomatic asthma in adults, especially in women. In 13-14-year-olds, only obesity increased the prevalence of asthma. In children, overweight was associated with increased prevalence of clinically diagnosed and declared asthma and a trend towards atopy. Higher BMI was negatively associated with the prevalence of allergic rhinitis in overweight and obese man. There was no correlation between BMI and sensitization to aeroallergens.

Epidemiological studies mainly from Europe, the USA and Asia indicate a high prevalence of allergic rhinitis (AR) in modern societies. However, little is known about AR among the heterogeneous population of the United Arab Emirates (UAE). To estimate the prevalence of AR and its independent risk factors in Al-Ain City, UAE. We used a validated, self-administered questionnaire modified from the ISAAC study to collect data from a two stage randomly selected sample of 10 000 school children. Overall, 7550 subjects (aged 13 years and above, siblings, and their parents) responded. We assessed the prevalence of AR (both crude and standardized prevalence of previous 12 months) as well as the independent relationship of AR with age, gender, education, nationality and family history by means of logistic regression. The response rate was 76%. A total of 6543 subjects (median age 30 years) were included in the final analysis. Self-reported prevalence of AR (having symptoms in the past 12 months) was 36%, while adjusted values for sex/age yielded a prevalence of 32%. Regression analysis revealed that AR was independently associated with family history, Arab origin, younger age, female gender and higher education. The relatively high prevalence of AR found in this study may be attributable to modernization and genetic factors. Further studies on the impact of rapid environmental and cultural changes on AR in the Arab countries are needed and currently planned in conjunction with GA(2)LEN (Global Allergy and Asthma European Network).

Abnormalities in the human microbiota are associated with the etiology of allergic diseases. Although disease site-specific microbiota may be associated with disease pathophysiology, the role of the nasal microbiota is unclear. We sought to characterize the microbiota of the site of allergic rhinitis, the inferior turbinate, in subjects with allergic rhinitis ( n = 20) and healthy controls ( n = 12) and to examine the relationship of mucosal microbiota with disease occurrence, sensitized allergen number, and allergen-specific and total IgE levels. Microbial dysbiosis correlated significantly with total IgE levels representing combined allergic responses but not with disease occurrence, the number of sensitized allergens, or house dust mite allergen-specific IgE levels. Compared to the populations in individuals with low total IgE levels (group IgE low ), low microbial biodiversity with a high relative abundance of Firmicutes phylum ( Staphylococcus aureus ) and a low relative abundance of Actinobacteria phylum ( Propionibacterium acnes ) was observed in individuals with high total serum IgE levels (group IgE high ). Phylogeny-based microbial functional potential predicted by the 16S rRNA gene indicated an increase in signal transduction-related genes and a decrease in energy metabolism-related genes in group IgE high as shown in the microbial features with atopic and/or inflammatory diseases. Thus, dysbiosis of the inferior turbinate mucosa microbiota, particularly an increase in S. aureus and a decrease in P. acnes , is linked to high total IgE levels in allergic rhinitis, suggesting that inferior turbinate microbiota may be affected by accumulated allergic responses against sensitized allergens and that site-specific microbial alterations play a potential role in disease pathophysiology.

Interaction between rhinitis and asthma: state of the art.

PubMed

Frieri, Marianne

2003-01-01

Rhinitis and asthma are very prevalent allergic disorders with comorbid features, similar risk factors, and environmental triggers. Pathophysiological processes are linked via tissue histopathology, immunologic pathway, and inflammatory mediators. Allergen challenge of the upper airway can increase lower-airway responsiveness and allergen challenge of the lower airway can lead to upper-airway inflammation. Both allergic rhinitis and asthma exert a high social and economic burden in significant loss of work and school days as well as impairment for children and adults.

To asses the effects of two topical nasal corticosteroids sprays on hyposmia in patients with persistent allergic rhinitis. The study was a prospective clinical trial and it included twenty four patients with persistent allergic rhinitis (PER) and hyposmia (H). The patients were divided into two groups depending on the type of corticosteroid topical nasal spray treatment: group A, 200 micrograms dose of mometasone furoate (MF) and group B, 110 micrograms dose of fluticasone furoate (FF) both administered in the morning for 4 weeks. The olfactory function of the patients was evaluated with the extended Test battery "Sniffin' Sticks". The visual analogue scale (VAS) was used for the assessment of hyposmia, nasal discharge. The level of the nasal obstruction, before and after the treatment, was evaluated through the anterior rhinomanometry. The comparisons between the two types of topical corticosteroids showed a significant improvement separately between scores of the odor threshold (OT), odor discrimination (OD) and odor identification (OI) and also on the final olfactory score (SDI) before and after 4 weeks of the treatment. The comparisons of the VAS scores pre and post treatment showed a significant improvement in hyposmia and nasal obstruction. The nasal airflow and the nasal discharge scores were improved, but the differences were not statistically significant between the groups. The final statistical analysis found no significant differences between the two patients groups. The study concludes that fluticasone furoate and mometasone furoate have quite the same effects on hyposmia and on the classical symptoms from PER.

Allergen sensitization is influenced by genetic and environmental factors; however, the factors related to sensitizations in patients with rhinitis and asthma in China are largely unknown. This study investigated the factors associated with allergen sensitizations in patients with asthma and rhinitis in China. A cross-sectional survey was performed in 6304 patients with asthma and/or rhinitis from four regions of China. Patients completed a standardized questionnaire related to respiratory and allergic symptoms, family history of allergic diseases, smoking history, environmental exposure, and eating behaviors. They underwent skin-prick tests (SPTs) with 13 common aeroallergens. Blood samples were collected from 2268 of patients for specific IgE (sIgE) measurements against 16 common aeroallergens. Patients with both asthma and rhinitis had higher prevalence of SPT and sIgE positivity to most allergens than those with asthma or rhinitis alone (p < 0.0001). Male gender, family history of allergic rhinitis, air-conditioner usage, sleeping on a mattress, and frequently eating meat were associated with increased risk of SPT and sIgE positivity. Using air-conditioner and sleeping on a mattress were further found to be associated with sIgE positivity to mites and molds. However, increased age and fish, fruit, and raw vegetable intake decreased the risk of SPT and sIgE positivity. Family history of allergic rhinitis, male gender, using an air conditioner, sleeping on a mattress, and frequent meat consumption are risk factors for allergen sensitizations, whereas increased age and frequent fish, fruit, and raw vegetable consumption may protect patients with asthma and/or rhinitis from developing sensitizations in China.

To evaluate patient perception of the onset of action and overall satisfaction with a fast-dissolving tablet (FDT) formulation of ebastine in patients with intermittent or persistent allergic rhinitis. This was a cross-sectional, multicenter, pharmacy-based survey involving adult patients (>18 years) with allergic rhinitis who presented with a prescription for ebastine FDT. Via a telephone interview, patients were asked to evaluate the characteristics of ebastine FDT in comparison with their previous experience with other antihistamines. 100 patients with allergic rhinitis were included in the study (41 had intermittent disease, 57 persistent disease and two with unknown disease states). Patients rated ebastine FDT very highly (mean scores: 4.5-4.7 out of a possible 5) for all characteristics related to convenience, such as easy to take, easy to carry around in a bag or pocket, suitable for taking anytime/anywhere, and convenient to use. A total of 85% of patients perceived ebastine FDTs onset of action to be fast or very fast, and 77% indicated that it acted faster than their usual antihistamine. A total of 96% were satisfied or very satisfied with ebastine FDT and 98% were interested in using the drug again. Patients with rhinitis rate ebastine FDT very highly in terms of its formulation, convenience of use and its rapid onset of action. These characteristics resulted in a high level of individual satisfaction with the new formulation and a clear preference by the majority of patients to use ebastine FDT in the future.

Perennial allergic rhinitis (PAR) is a chronic inflammatory nasal condition in individuals exposed year-round to allergens. This was a double-blind study of 15- to 85-year-old patients randomly allocated to montelukast, 10 mg (n=630), placebo (n=613), or the positive control cetirizine, 10 mg (n=122) for 6 weeks. The primary efficacy end point was change from baseline in Daytime Nasal Symptoms Score (DNSS; mean of congestion, rhinorrhea, sneezing, and itching scores, rated daily by patients [scale: 0=none to 3=severe]) averaged during the initial 4 weeks (primary analysis) or entire 6 weeks of treatment. Also assessed were combined post hoc results of primary end point data from this study and another similarly designed study (Patel P, et al. Randomized, double-blind, placebo-controlled study of montelukast for treating perennial allergic rhinitis, Ann Allergy Asthma Immunol 95:551, 2005). Over 4 weeks, montelukast showed numerical improvement over placebo in DNSS (least-squares mean difference of -0.04 [95% confidence interval (CI}, -0.09, 0.01]); the difference between cetirizine and placebo was significant: -0.10 (95% CI, -0.19, -0.01). However, when averaged over 6 weeks, neither active treatment was significantly different from placebo. The Rhinoconjunctivitis Quality-of-Life score was significantly improved by montelukast (p < 0.05), but not by cetirizine, during 4 and 6 weeks. The treatment effect of montelukast, but not cetirizine, generally remained consistent through the 6 weeks of treatment. In pooled data, montelukast consistently improved DNSS versus placebo during all 6 weeks of treatment (-0.07 [95% CI, -0.10, -0.041). In conclusion, montelukast produced numerical improvement in daytime nasal symptoms and significant improvement in quality of life. In a pooled post hoc analysis, montelukast provided consistent improvement in daytime nasal symptoms over 6 weeks, supportive of an overall benefit in PAR.

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

Background Allergic disorders have become a major public health concern worldwide. No Nigerian study has examined the epidemiology of allergic diseases among women. Aim To document the prevalence, risk factors and the changes in the symptoms of allergic disorders during pregnancy. Settings and Design Cross-sectional study conducted at the booking and antenatal clinics of LAUTECH Teaching Hospital and Millennium Development Goals (MDG) Clinic of the Comprehensive Health Center, Oja Igbo, Ogbomoso, Nigeria. Materials and Methods Study enrolled 432 women from two public hospitals. Sociodemographic and clinical history were obtained and allergic disorders were diagnosed using ISAAC questionnaires. Results The prevalence of wheezing, eczema and rhinitis in pregnancy are 7.5%, 4.0% and 5.8% respectively. The prevalence of wheezing and eczema was slightly higher among the pregnant in past 12 months. Wheeze worsened in 70% (18/26), improved in 15% (2/26), and stable in 15% (2/26). Eczema worsened in 50% (7/14), improved in 7.1% (1/14) and stable in 42.9% (6/14), while allergic rhinitis worsened in 50% (11/22), improved in 22.7% (5/22) and stabilized in 27.3 % (6/22). In multivariate analysis, the risk of allergic diseases in pregnancy was increase 2 times by low income earning (CI: 1.2 – 2.1, p = 0.002), low level education (OR = 0.6, CI: 0.3 – 0.9, p = 0.011) and by family history of asthma, OR-4.3, CI – 1.3 – 13.9, p = 0.015. Family history of asthma increase the chances of asthma by 18.7 times, CI-2.3 – 152.2, p = 0.006, while the odd of eczema was increased 9.1 times (CI-2.7 – 30.6, p<0.001) and 2.4 times (CI: 1.2 – 4.7, p = 0.008) by second hand home smoking and low-family income respectively. The risk of allergic rhinitis were raised 1.8 times by low family income (CI 1.1 – 2.8, p = 0.013) and 3.9 times by family history of rhinitis (OR = 3.9, CI 1.2 – 12.7, p = 0.024). Conclusion Prevalence of wheezing and eczema are higher in pregnancy probably

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.

Chronic rhinitis (CR) is one of the most common causes accounting for lost-school days, absenteeism and resource utilization in pediatric patients. Distinction between common causes of CR, allergic (AR)and non-allergic rhinitis (NAR), based upon clinical features is critical, especially in primary care settings or facilities with lack of allergen sensitivity testing, as management strategies differ considerably. The current study elucidates clinical factors, particularly facial features associated with AR and NAR using a large cohort. In a retrospective cohort analysis of pediatric patients aged 6-18 years, we assessed patient demographics, clinical symptoms, and signs associated with allergic rhinitis using multivariable regression techniques. Overall, 1490 patients (mean age: 10.11 ± 3.31 years; 48% female; 69% AR and 31% NAR) were included in the study. In multivariable regression analysis, major clinical features associated with AR were: sneezing (OR: 3.53; 95% CI: 2.35-5.32; p < 0.001), rhinorrhea (OR: 1.77; 95% CI: 1.18-2.66; p = 0.006), nasal itching (OR: 17.88; 95% CI: 11.92-26.83; p < 0.001), horizontal nasal crease (OR: 5.09; 95% CI: 1.29-20.01; p = 0.020) and conjunctivitis (OR: 4.66; 95% CI: 3.28-6.62; p < 0.001). On the contrary, we noted presence of Dennie-Morgan fold (OR: 1.67; 95% CI: 1.11-2.56; p = 0.014), moderate to severe persistent or intermittent symptoms to be likely associated with NAR than AR. In pediatric patients presenting with symptoms of rhinitis, facial hallmarks serve as an adjunct to sensitivity testing in establishing a diagnosis as well as differentiating between NAR from AR, albeit individualized upon patient history and clinical features.

Studies in animals have suggested that lactic acid bacteria alleviate allergic diseases, however, little information is available on their clinical effect on allergy in humans. Thus, we examined the efficacy of orally administered Lactobacillus acidophilus strain L-92 (L-92) on perennial allergic rhinitis. In a randomized, double-blind, placebo-controlled clinical trial, 49 patients with perennial allergic rhinitis were randomized to receive either 100 mL of heat-treated fermented milk containing L-92 (n = 25) or acidified milk without lactic acid bacteria (placebo; n = 24) for 8 wk. The severity of symptoms was evaluated based on the changes in the scores of clinical symptoms. Oral administration of milk fermented with L-92 resulted in a statistically significant improvement of nasal symptom-medication scores. Ocular symptom-medication scores of patients in the L-92 intervention group tended to improve compared with those in the placebo group. In addition, clear decreases of the scores of swelling and color of the nasal mucosa were observed in the L-92 intervention group at 6 and 8 wk after the start of ingestion of fermented milk. There were no significant differences in serum antihouse dust mite immunoglobulin E levels nor in T helper type 1/T helper type 2 ratio between the 2 groups. These results suggest that oral administration of L-92 can alleviate the symptoms of perennial allergic rhinitis, however, statistically significant changes were not shown in blood parameters.

Consensus has not been reached regarding the optimal reduction procedure for inferior turbinate hypertrophy in allergic rhinitis and whether such procedures result in improvement in mucosal architecture. Twenty-nine patients aged 18-45 years (mean 26.8 years), with allergic rhinitis and inferior turbinate hypertrophy not responsive to medical therapy who underwent endoscopic submucosal diathermy (ESMD) (14 patients) or endoscopic submucosal resection (ESMR) (15 patients) with intraoperative and 3-6 months postoperative inferior turbinate biopsies, were included in the study. Epithelial and mucosal architecture was compared between the two groups. Both groups showed a significant decrease in epithelial denudation (p < 0.001), reversal of basement membrane thickening (p < 0.001) and increase in density of cilia (p < 0.001). The degree of improvement in histological characteristics between ESMD and ESMR groups was not significant. Surgical intervention for inferior turbinate hypertrophy by both ESMD and ESMR results in significant restoration of nasal mucosal epithelium in patients with allergic rhinitis as early as 3-month postoperatively. There was, however, no significant difference in the histological changes between those who underwent ESMD and ESMR. CTRI/2015/01/005373.

To verify the effect of a new nasal spray made from natural medicines on allergic rhinitis in animals. Methods: The main natural medicines contained in Acusine nasal spray plus essential traditional Chinese medicine contained in drugs for allergic rhinitis in Chinese market were used. By preparation process of extraction of traditional Chinese medicine such as steam distillation, ethanol extraction, a new nasal spray made from natural medicines was prepared. In the meantime, 24 BALB/c mice and New Zealand white rabbits were used. Then, mice were randomly divided into four group; control group, beclomethasone dipropionate group, Acusine group and new spray group, 6 mice in each group. Moreover, the effect of the new nasal spray made on passive cutaneous anaphylaxis was conducted by detecting absorptions of Evan’s blue (620nm) in the four groups. Allergic rhinitis models in 40 New Zealand white rabbits were established. Consequently, 40 allergic rhinitis models in rabbits were randomly divided into control group, Acusine group and new spray group, 10 rabbits in each group. The four groups were sprayed nasally with saline, Acusine spray and new spray respectively, three times/d, for 30 days. The nasal resistances in the four groups were measured with a rhinoresistometer. Moreover, their nasal mucosa was taken for HE staining. Consequently, their pathological manifestations were observed. The results: Absorption of Evan’s blue (620nm) of new spray group will be found significantly lower than Acusine group (P<0.05) and will have no significantly difference compared with beclomethasone dipropionate group(P>0.05). On the other hand, absorption of Evan’s blue (620nm) of beclomethasone dipropionate group will be significantly lower than Acusine group (P<0.05). Moreover, The nasal resistances of new spray group will be significantly lower than Acusine group (P<0.05) and will have no significantly difference compared with beclomethasone dipropionate group (P».05

To compare the prevalence of food allergy for peanut, shrimp, and milk in adults with allergic rhinitis and to determine predictive values of these allergens and total immunoglobulin E (IgE) to detect food allergies. Cross-sectional study. University of Chicago Medical Center, Chicago, Illinois. We retrospectively analyzed in vitro enzyme-linked immunosorbent assays of adults with rhinitis. Subjects were tested for nine inhalants and three foods (peanut, shrimp, milk) and total IgE. Subjects with food allergy history were tested with additional foods. The sensitivity (SE), specificity (SP), positive predictive value (PPV), and negative predictive value (NPV) of the allergens and total IgE to detect food allergies were calculated. A total of 283 subjects received in vitro tests. Forty-one percent tested negative and 59 percent tested positive for inhalants. The prevalence of subjects with a positive peanut or shrimp allergy in the inhalant-positive population was significantly greater than subjects with milk allergy (23.4% peanut [P = 0.008], 22.2% shrimp [P = 0.001], and 13.2% milk [P = 0.008], P = 0.001). For subjects with food allergy history, peanut had the best SP (100.0%), SE (28.1%), PPV (100.0%), and NPV (64.6%) in detecting allergies to other foods. In patients positive for the initial panel (inhalants and peanut), the SP, SE, PPV, and NPV of elevated total IgE was 71.4, 72.4, 77.8, and 65.2 percent, respectively. Peanut and shrimp were the most common foods encountered in adults with allergic rhinitis. Peanut was best in predicting other food allergies. Total IgE levels with inhalants plus peanut provided the optimal combination of SE, SP, PPV, and NPV. In vitro testing may be important to identify and prevent anaphylaxis to foods in adults.

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

Allergic rhinitis (AR) is a common inflammation of the nasal mucosa in response to allergen exposure. We translated and validated the Score for Allergic Rhinitis (SFAR) into an Arabic version so that the disease can be studied in an Arabic population. SFAR is a non-invasive self-administered tool that evaluates eight items related to AR. This study aimed to translate and culturally adapt the SFAR questionnaire into Arabic, and assess the validity, consistency, and reliability of the translated version in an Arabic-speaking population of patients with suspected AR. Cross-sectional. Tertiary care hospital in Riyadh. The Arabic version of the SFAR was administered to patients with suspected AR and control participants. Comparison of the AR and control groups to determine the test-retest reliability and internal consistency of the instrument. The AR (n=173) and control (n=75) groups had significantly different Arabic SFAR scores (P < .0001). The instrument provided satisfactory internal consistency (Cronbach's alpha value of 0.7). The test-retest reliability was excellent for the total Arabic SFAR score (r =0.836, P < .0001). These findings demonstrate that the Arabic version of the SFAR is a valid tool that can be used to screen Arabic speakers with suspected AR. The absence of objective allergy testing.

The following paper reviews the latest news on antihistamines used in the treatment of allergic rhinitis. It describes the new results of investigations on clinical application of H3 and H4 receptors in therapy of allergic diseases as well as the effect of emedastine on histamine-induced tissue remodeling. Contemporary clinical research of these drugs fulfills the requirements of placebo-controlled trials, including the comparison with a reference drug, usually cetirizine. The paper discusses efficacy and safety of a new drug--bilastine, and the possibility to improve clinical outcome by combining antihistamine drugs with inhaled glucocorticosteroids and antileukotrienes. It also presents the studies on high efficacy of nasal antihistamines, which most probably results from their high concentration in inflamed tissue, as well as describes the latest news on safe use of antihistamines, including studies of fexofenadine enantiomers in drug interactions with P-glycoprotein, safety of a new antihistamine medication--rupatadine, and psychostimulating effect of some other antihistamines. The review shows that antihistamines, the most frequently used class of anti-allergy medications, have been constantly improved, which is of significant importance for progress of allergic diseases treatment.

Allergic rhinitis has long been a worldwide health problem with a global growth trend. The use of traditional Chinese medicines alone or integrated Chinese-Western medicines for its treatment is quite common in Taiwan. Respiratory diseases account for the majority of outpatient traditional Chinese medicine treatment, while allergic rhinitis accounts for the majority of respiratory diseases. We hereby conduct a comparative analysis between traditional Chinese medicine treatments and western medicine treatments for allergic rhinitis in Taiwan. The results of the analysis on the prescription difference of traditional Chinese medicine and western medicine treatments would be helpful to clinical guide and health policy decision making of ethnopharmacological therapy. Patients diagnosed as allergic rhinitis with diagnostic code 470-478 (ICD-9-CM) were selected as subjects from 2009-2010 National Health Insurance Research Database based on the claim data from the nationwide National Health Insurance in Taiwan. This retrospective study used Chi-Square test to test the effects of gender and age on visit of traditional Chinese medicine, western medicine, and integrated Chinese-Western medicine treatments. A total of 45,804 patients diagnosed as allergic rhinitis with ICD-9-CM 470-478 were identified from 2009-2010 NHIRD. There were 36,874 subjects for western medicine treatment alone, 5829 subjects for traditional Chinese medicine treatment alone, and 3101 subjects for integrated Chinese-Western medicine treatment. Female patients were more than male in three treatments. 0-9 years children had the highest visit frequency in western medicine and integrated Chinese-Western medicine groups, while 10-19 years young-age rank the highest in traditional Chinese medicine group. The Chi-square test of independence showed that the effects of gender and age on visit of three treatments were significant. The prescription drugs of western medicine treatment alone were almost for

This study aimed to examine whether citrus juice fermented with Lactobacillus plantarum YIT 0132 (LP0132), which was pasteurised after fermentation, could alleviate the symptoms of perennial allergic rhinitis in a double-blind, placebo-controlled, parallel-group trial. Subjects with perennial allergic rhinitis consumed LP0132-fermented juice (n=17) or unfermented citrus juice (placebo; n=16) once a day for 8 weeks. During the pre-intervention and intervention periods, the subjects recorded nasal symptoms (number of sneezing attacks, number of nose-blowing incidents, and stuffy nose score). The primary endpoint, nasal symptoms score (NSS), was scored from 0 to 4 according to the 'Practical Guideline for the Management of Allergic Rhinitis in Japan 2009' using a combination of the three nasal symptom items. Blood samples were collected at pre-intervention and at 8 weeks after commencing the intervention. There were several significant improvements not only in the LP0132 group but also in the placebo group because of potential anti-allergic effects of citrus. Compared with the placebo group, the LP0132 group showed a significant reduction in the NSS and stuffy nose score during the intervention period. Also, the LP0132 group, but not the placebo group, showed significant attenuation of type 2 helper T cells (Th2 cells)/helper T cells, serum total immunoglobulin E (IgE), and eosinophil cationic protein (ECP), and showed significant augmentation of type 1 helper T cells (Th1 cells)/Th2 cells at 8 weeks of intervention compared with baseline. It is suggested that daily intake of fermented citrus juice containing heat-killed LP0132 has beneficial effects on symptoms of perennial allergic rhinitis, and these benefits may be associated with the attenuation of Th2 cells, total IgE, and ECP via the immunomodulating activities of LP0132.

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.

Allergic rhinitis (AR) has become the most prevalent chronic allergic disorder in childhood, and the role of environment has been questioned, particularly in early life. To investigate the risk factors for rhinitis symptoms in infants included in the PARIS (Pollution and Asthma Risk: an Infant Study) birth cohort. Infants were invited to participate at age 18 months in a health examination conducted by a pediatrician. Allergic rhinitis was defined as the presence of rhinitis symptoms (runny nose, blocked nose, sneezing in the absence of a cold) combined with biological atopy (elevated total immunoglobulin E [IgE], specific IgE, or eosinophilia) and nonallergic rhinitis (NAR) as symptoms without biological atopy. Information about indoor exposures and lifestyle was collected during a telephone interview when the child was 1 month of age. Risk factors for AR and NAR were studied by using a polytomous regression model. The prevalence of AR and NAR was 70/1,850 (3.8%) and 99/1,850 (5.4%), respectively. Allergic rhinitis and NAR did not share similar risk factors. Male sex (odds ratio [OR] = 1.99 [1.19-3.32]), parental history of AR (OR = 1.89 [1.16-3.08]), low socioeconomic class (OR = 2.23 [1.05-4.72] for low vs high level), and the presence of cockroaches in the home (OR = 3.15 [1.67-5.96]) were risk factors for AR. Conversely, the presence of particle-board furniture less than 12 months old in the child's bedroom was associated with an increased risk of NAR (OR = 1.87 [1.21-2.90]). This study should raise awareness about the impact of indoor exposures, particularly with regard to cockroaches and particle-board furniture, because they could influence the occurrence of noninfectious rhinitis.

Sublingual-specific immunotherapy (SLIT) is considered as a valid treatment of respiratory allergies. We performed a case-control study to evaluate the effect of SLIT in children with allergic asthma and rhinitis. The study plan included 140 patients (age 6-14 yr, 43% girls and 57% boys) presenting allergic rhinitis and/or asthma, 70 treated with SLIT actively for three years and 70 controls never treated with specific immunotherapy (only symptomatic drugs). Rhinitis Symptom Score (RSS), Asthma Symptom Score (ASS) and Medication Score (MS) were evaluated at beginning and during the 3 years of immunotherapy. results: There was a significant improvement of RSS (mean ± SD) in the SLIT group: baseline 5.31 ± 2.01, third year 1.38 ± 1.06 (p < 0.0001 vs baseline). baseline 5.00 ± 1.08, third year 4.68 ± 1.152 (P ¼ NS). ASS (mean ± SD) in the SLIT group: baseline 4.09 ± 2.21, third year 1.23 ± 1.4 (p < 0.0001 vs baseline). baseline 4.04 ± 2.46, third year 3.62 ± 2.26 (p ¼ NS). MS (mean ± SD) in the SLIT group: baseline 3.30 ± 1.4, third year 0.88 ± 1.26 (p < 0.0001 vs baseline). baseline 3.19 ± 1.23, third year 3.39 ± 1.12 (p ¼ NS). There are no statistically significant differences among monosensitized/polysensitized patients and at different age ranges. None of the patients included reported severe systemic reactions or anaphylaxis. During the treatment, the active group showed sustained reductions in mean asthma and rhinitis symptom scores when compared with controls to confirm the efficacy and safety of sublingual immunotherapy.

Increased frequency of migraine was reported in adults with allergic rhinitis (AR). Although migraine is less common in children than in adults, it can begin in early childhood and persist into adulthood. We conducted this population-based cohort study to investigate the incidence and subsequent risk of migraine in children with AR. From 2000 to 2007, 461,850 children with recently diagnosed AR and 460,718 non-AR controls were included in the study. By the end of 2008, incidences of migraine in both cohorts, the AR to non-AR cohort hazard ratios (HRs), and confidence intervals (CIs) were measured. The incidence of migraine during the study period was 3.2-fold higher in the AR cohort (95% CI, 2.97 to 3.46) than in the non-AR cohort (11.4 vs 3.49 per 10000 person-years). The risk was greater for boys than for girls, and for children aged <6 years. The HR for migraine in children with AR was 1.44 (95% CI, 1.31 to 1.58) for those with ≤2 annual AR-related medical visits, whereas, 14.8 (95% CI, 13.6 to 16.2) for those with >4 visits (p < 0.0001, the trend test). The risk of migraine development in the AR cohort was highest within the first year after AR diagnosis (HR 4.89; 95% CI, 3.98 to 6.00). Children with AR were more likely to have migraine without aura than migraine with aura. Children with AR had a higher incidence and subsequent risk of migraine. Physicians should be more aware of migraine in children with AR who complain of headache. © 2015 ARS-AAOA, LLC.

Intranasal exposure to monoclonal antibody Fab fragments to Japanese cedar pollen Cry j1 suppresses Japanese cedar pollen‐induced allergic rhinitis

Background and Purpose Fab fragments (Fabs) of antibodies have the ability to bind to specific allergens but lack the Fc portion that exerts effector functions via binding to receptors including FcεR1 on mast cells. In the present study, we investigated whether intranasal administration of the effector function‐lacking Fabs of a monoclonal antibody IgG1 (mAb, P1‐8) to the major allergen Cry j1 of Japanese cedar pollen (JCP) suppressed JCP‐induced allergic rhinitis in mice. Experimental Approach Balb/c mice sensitized with JCP on days 0 and 14 were challenged intranasally with the pollen on days 28, 29, 30 and 35. Fabs prepared by the digestion of P1‐8 with papain were also administered intranasally 15 min before each JCP challenge. Key Results Intranasal administration of P1‐8 Fabs was followed by marked suppression of sneezing and nasal rubbing in mice with JCP‐induced allergic rhinitis. The suppression of these allergic symptoms by P1‐8 Fabs was associated with decreases in mast cells and eosinophils and decreased hyperplasia of goblet cells in the nasal mucosa. Conclusions and Implications These results demonstrated that intranasal exposure to P1‐8 Fabs was effective in suppressing JCP‐induced allergic rhinitis in mice, suggesting that allergen‐specific mAb Fabs might be used as a tool to regulate allergic pollinosis.

In previous research, patients with seasonal allergic rhinitis (SAR) showed poorer school and work performance during periods of acute allergic inflammation, supporting the idea of an impact of SAR on cognitive functions. However, the specific cognitive domains particularly vulnerable to inflammatory processes are unclear. In this study, the influence of SAR on memory and multitasking performance, as two potentially vulnerable cognitive domains essential in everyday life functioning, was investigated in patients with SAR. Non-medicated patients with SAR (n = 41) and healthy non-allergic controls (n = 42) performed a dual-task paradigm and a verbal learning and memory test during and out of symptomatic allergy periods (pollen vs. non-pollen season). Disease-related factors (e.g. symptom severity, duration of symptoms, duration of disease) and allergy-related quality of life were evaluated as potential influences of cognitive performance. During the symptomatic allergy period, patients showed (1) poorer performance in word list-based learning (P = 0.028) and (2) a general slowing in processing speed (P < 0.001) and a shift in processing strategy (P < 0.001) in multitasking. Yet, typical parameters indicating specific multitasking costs were not affected. A significant negative association was found between learning performance and duration of disease (r = -0.451, P = 0.004), whereas symptom severity (r = 0.326; P = 0.037) and quality of life (r = 0.379; P = 0.015) were positively associated with multitasking strategy. Our findings suggest that SAR has a differentiated and complex impact on cognitive functions, which should be considered in the management of SAR symptoms. They also call attention to the importance of selecting sensitive measures and carefully interpreting cognitive outcomes. © 2017 John Wiley & Sons Ltd.

Asthma and/or allergic rhinitis have been associated with sleep disorders. The aim of this study was to evaluate sleep disorders in Latin-American children (4-10 years) from nine countries, with persistent asthma (A) and/or allergic rhinitis (AR) and in normal controls (C). Parents from 454 C children and 700 A and/or AR children followed up in allergy reference clinics completed the Children's Sleep Habits Questionnaire (CSHQ) which is a retrospective one-week questionnaire composed of 33 questions composed of seven subscales (bedtime resistance, sleep duration, sleep anxiety, night wakings, parasomnias, sleep-disordered breathing and daytime sleepiness). The total scale of CSHQ and the subscales were compared between groups C and A+AR, A (n=285) vs. AR (n=390), and between controlled A (CA, n=103) vs. partially controlled/uncontrolled A (UA, n=182). The comparison between C and A+AR showed no significant differences in age (6.7 years vs. 7.0 years, respectively), mean Body Mass Index and total scale of CSHQ (53.3 vs. 63.2, respectively) and the subscales were significantly higher in the A+AR group. Comparison between groups A and AR, except for sleep anxiety, showed significantly higher values for CSHQ total scale (66.9 vs. 61.0, respectively) and subscales for group A. The UA group showed significantly higher values for total CSHQ scale and subscales in comparison to CA (71.1 vs. 59.4, respectively). Latin-American children with asthma and/or allergic rhinitis showed sleep disorders identified by the CSHQ when compared to normal controls. Despite being treated, asthma causes sleep impairment, especially when uncontrolled. Copyright © 2016 SEICAP. Published by Elsevier España, S.L.U. All rights reserved.

Their signs and symptoms, eosinophil percentage on nasal smear, serum IgE, and interleukin IL-4, IL-5, interferon- γ) levels were recorded. Forty patients completed the trial. Based on the Sino- Nasal Outcome Test 22 SNOT-22), a significant improvement in clinical symptom severity was observed in both groups P < .001). Furthermore, a statistically significant reduction in mean nasal smear eosinophil count was observed after treatment with Nettle P < .01). However, the mean IgE and IL4 and IL5 levels in the study group before and after treatment with Nettle saw no significant changes P > .1). Intergroup pre- and post-treatment laboratory findings suggested that there was a significant difference in post-treatment changes of mean IFN γ levels between the study and placebo group P = 0.017). Although the current study showed certain positive effects of Nettle in the management of allergic rhinitis on controlling the symptoms based on the SNOT-22, similar effects were demonstrated by placebo as well. We believe that our limitations underscore the need for larger, longer term studies of Nettle for the treatment of allergic rhinitis. PMID:29844782

To obtain the prevalence and related factors in allergic rhinitis (AR) and other allergic diseases in rural area in China through epidemiological investigation with large sample and multi-faceted survey data. Face to face survey was conducted in different regions (rural areas of Cangzhou, Hebei, coastal fishing village of Bohai Bay, area of Wuling Mountain, Chengde, urban areas of Tianjin) from April 2007 to May 2009. In the same time, serum specific IgE (sIgE) was detected in the digits of every 0, 1or 5 in them. SPSS 13.0 software was used to analyze the data. Five thousand and ten cases were investigated. There were 823 cases with the symptoms or signs of AR (16.4%). Four hundred and two cases were found to have positive serum sIgE antibody in 1576 detected cases (25.5%). One hundred and fourty-six cases with nasal allergic symptoms or signs were diagnosed as AR. The incidence of AR was 9.3% (146/1576). The occurrence of allergic symptoms or signs had a significant statistical difference with factors such as age, occupation, atopic constitution (χ(2) value were 7.96, 9.73, 16.53, 8.95 respectively, all P < 0.05), and it was closely related to lower respiratory tract allergies (β = 2.544, P < 0.01). The most common allergens were dog and cat epithelium in rural areas and dust mites in city. The incidence of AR is higher whether in urban or rural areas, it should be taken seriously as the impact on human health. The occurrence is closely related to physical characteristics and environmental factors.

The use of allergen immunotherapy (AIT) for allergic rhinitis and its clinical efficacy in clinical trials depends on the effective determination of pollen allergens exposure time-periods. We evaluate pollen data from Germany to examine the new definitions on pollen season and peak pollen period start and end as proposed by the European Academy of Allergy and Clinical Immunology (EAACI) in a recently published Position Paper. The aim was to demonstrate the ability of these definitions to mirror symptom loads for grass and birch pollen-induced allergic rhinitis based on real-life data. Data coming from four Pollen monitoring stations in the Berlin and Brandenburg area in Germany and for 3 years (2014 - 2016) were used to investigate the correlation of season definitions, birch and grass pollen counts and total nasal symptom and mediation scores as reported by patients in "Patients Hayfever Diaries" (PHDs). After the identification of pollen periods on the basis of the EACCI criteria, a statistical analysis was employed, followed by a detailed graphical investigation. The analysis revealed that the definitions of pollen season as well as peak pollen period start and end as proposed by the EAACI are correlated to symptom loads for grass and birch pollen-induced allergic rhinitis reported by patients in PHDs. Based on our analysis, the validity of the EAACI definitions on pollen season is confirmed. Their use is recommended in future clinical trials on AIT as well as in daily routine for optimal patient care. This article is protected by copyright. All rights reserved.

Efficacy, effectiveness and cost-effectiveness of acupuncture for allergic rhinitis - An overview about previous and ongoing studies.

PubMed

Witt, C M; Brinkhaus, B

2010-10-28

In general, allergic rhinitis can be divided into seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR). In the following sections a summary of efficacy and effectiveness studies is presented. For this narrative review we selected studies based on the following parameters: publication in English, sample size ≥30 patients, and at least 6 acupuncture sessions. Most studies aimed to evaluate the specific effects of acupuncture treatment. Only one study evaluated effectiveness and cost-effectiveness of additional acupuncture treatment. The studies which compared acupuncture with sham acupuncture always used a penetrating sham control. A medication control group was used in only two studies and one study combined acupuncture and Chinese herbal medicine. This overview shows that the trials on efficacy and on effectiveness of acupuncture are very heterogeneous. Although penetrating sham controls were used predominantly, these also varied from superficial penetration at acupuncture points to superficial insertion at non-acupuncture points. Although there is some evidence that acupuncture as additional treatment is beneficial and relatively cost-effective, there is insufficient evidence for an acupuncture specific effect in SAR. In contrast, there is some evidence that acupuncture might have specific effects in patients with PAR. However, all of the published efficacy studies are small and conclusions should be made with care. Further studies with a larger sample size are urgently needed to draw more rigorous conclusions and the results of the ongoing trials will provide us with further information within the next two years.

Evaluation of eicosanoids in nasal lavage as biomarkers of inflammation in patients with allergic rhinitis

PubMed Central

Górski, Paweł; Antczak, Adam

2014-01-01

Introduction Cysteinyl leukotrienes (cys-LTs), 8-isoprostane and prostaglandin E2 (PGE2) constitute fundamental mediators in allergic inflammation; therefore we wanted to determine the utility of PGE2, 8-isoprostane and cys-LT levels in nasal lavage as biomarkers of allergic inflammation. Material and methods Twenty-one patients with allergic rhinitis (AR) were included on the basis of a positive history of AR symptoms and positive results of skin prick tests to grass pollen allergens. The main exclusion criteria were: uncontrolled asthma, nasal polyps, respiratory infection, tuberculosis, neoplastic and autoimmune diseases, current smoking and immunotherapy. Both outside the pollen season and at the height of the pollen season, total nasal symptom score (TNS-4) was evaluated and the levels of cys-LTs, 8-isoprostane and PGE2 were measured in nasal lavage fluid (NALF). Results Natural allergen stimulation resulted in a significant increase of TNS-4 (p < 0.001) and nasal eosinophilia (p < 0.001). The concentration of PGE2 dominated in the NALF outside the pollen season and decreased significantly at the height of natural exposure (p < 0.01). In contrast, lower baseline concentrations of cys-LTs and 8-isoprostane increased significantly upon allergen stimulation (p < 0.05). There was a significant correlation between mean concentration of PGE2 and eosinophil number in NALF (r = 0.67, p = 0.0439). Conclusions The NALF concentrations of cys-LTs and 8-isoprostane change simultaneously with TNS-4 and nasal eosinophilia. However, due to the lack of any significant correlation, their utility as markers of allergic rhinitis should be warily considered. The decrease of PGE2 concentration in NALF which correlated with nasal eosinophilia may participate in escalation of allergic inflammation and needs further evaluation. PMID:25624848

Botulinum Toxin for Rhinitis.

PubMed

Ozcan, Cengiz; Ismi, Onur

2016-08-01

Rhinitis is a common clinical entity. Besides nasal obstruction, itching, and sneezing, one of the most important symptoms of rhinitis is nasal hypersecretion produced by nasal glands and exudate from the nasal vascular bed. Allergic rhinitis is an IgE-mediated inflammatory reaction of nasal mucosa after exposure to environmental allergens. Idiopathic rhinitis describes rhinitis symptoms that occur after non-allergic, noninfectious irritants. Specific allergen avoidance, topical nasal decongestants, nasal corticosteroids, immunotherapy, and sinonasal surgery are the main treatment options. Because the current treatment modalities are not enough for reducing rhinorrhea in some patients, novel treatment options are required to solve this problem. Botulinum toxin is an exotoxin generated by Clostridium botulinum. It disturbs the signal transmission at the neuromuscular and neuroglandular junction by inhibiting the acetylcholine release from the presynaptic nerve terminal. It has been widely used in neuromuscular, hypersecretory, and autonomic nerve system disorders. There have been a lot of published articles concerning the effect of this toxin on rhinitis symptoms. Based on the results of these reports, intranasal botulinum toxin A administration appears to be a safe and effective treatment method for decreasing rhinitis symptoms in rhinitis patients with a long-lasting effect. Botulinum toxin type A will be a good treatment option for the chronic rhinitis patients who are resistant to other treatment methods.

To investigate the genetic association pattern between single-nucleotide polymorphisms (SNP) in the interleukin-1 receptor-associated kinase 4 (IRAK-4) gene and allergic rhinitis (AR). A population of 379 patients with the diagnosis of AR and 333 healthy controls who lived in Beijing region was recruited. A total of 8 reprehensive marker SNP which were in IRAK-4 gene region were selected according to the Beijing people database from Hapmap website. The individual genotyping was performed by MassARRAY platform. SPSS 13.0 software was used for statistic analysis. Subgroup analysis for the presence of different allergen sensitivities displayed associations only in the house dust mite-allergic cohorts (rs3794262: P = 0.0034, OR = 1.7388; rs4251481: P = 0.0023, OR = 2.6593), but not in subjects who were allergic to pollens as well as mix allergens. The potential genetic contribution of the IRAK-4 gene to AR demonstrated an allergen-dependant association pattern in Chinese population.

Perennial allergic rhinitis (PAR) exerts significant quality-of-life and economic burdens on society. Beclomethasone dipropionate (BDP) nasal aerosol is the first nonaqueous, hydrofluoroalkane-propelled intranasal corticosteroid approved for patients in the United States to treat PAR and seasonal allergic rhinitis. To evaluate real-world effectiveness of BDP nasal aerosol from the patient's perspective by using a postmarketing observational registry. Patients (N = 824) from 43 U.S. study sites completed monthly patient-reported outcome instruments, including the Rhinitis Control Assessment Test (primary outcome variable), Treatment Satisfaction Questionnaire for Medication, Work Productivity and Activity Impairment Questionnaire plus Classroom Impairment Questions: Allergy-Specific, Pittsburgh Sleep Quality Index, and Mini Rhinoconjunctivitis Quality of Life Questionnaire for 6 months. The primary outcome assessment (Rhinitis Control Assessment Test score) (N = 527) indicated significant symptomatic improvement over baseline beginning at month 1 (p < 0.001), with >78.8% of respondents who achieved clinically meaningful improvement over 6 months. Secondary outcome measures Mini Rhinoconjunctivitis Quality of Life Questionnaire (p < 0.001), Pittsburgh Sleep Quality Index (p < 0.001), and Treatment Satisfaction Questionnaire for Medication-9 scales of effectiveness (p < 0.001), global satisfaction (p = 0.001), and patient-rated convenience (p = 0.03), significantly increased from baseline to month 6. Five of seven measurements of the Work Productivity and Activity Impairment Questionnaire plus Classroom Impairment Questions: Allergy-Specific, with the exception of work time missed and class time missed, were significantly (p < 0.001) improved in patients treated with BDP compared with baseline. Treatment with nonaqueous BDP nasal aerosol in a real-world setting significantly improved PAR symptoms and measures of quality of life, work, and school-related activities

Thyroid peroxidase (TPO) is the key enzyme in the biosynthesis of thyroid hormones T3 and T4. Autoimmune thyroiditis is a common disorder affecting 10% of population worldwide. A key feature of autoimmune thyroiditis is the presence of anti TPO antibodies, and some mutation of the TPO gene. Association between autoimmune thyroiditis and other autoimmune disorders has been reported but little is known about association with allergic diseases. In this study, we aimed to evaluate frequency of hidden autoimmune thyroiditis among allergic patient and examine possible relationship between anti-TPO levels and polymorphism at the TPO gene A2173/C exon 12 and different types of allergens. The study included 50 adult Egyptian patients with allergic rhinitis and /or bronchial asthma and 50 controls. For each subject, thyroid stimulating hormone (TSH), thyroxin 4 (T4) and Triiodothyronine (T3) hormones were measured. Anti-thyroid peroxidase (anti-TPO) level was detected by ELISA; and TPO gene polymorphism 2173A>C exon 12 was analyzed using restriction fragment length polymorphism (RFLP). Skin prick test was done to assess allergic response in patients. Serum levels of T3, T4 and TSH did not show any statistical significant difference between patients and groups. However, mean serum anti-TPO level was statistically higher in patients than controls, and correlated positively with body mass index, age, diastolic blood pressure, suggesting higher prevalence of hidden autoimmune thyroiditis in allergic patients than in control group. 2173A>C Genotyping revealed that the frequency of C allele is increased in the patient group. C allele represents a risk factor with odds ratio of 2.37 (1.035-5.44) and a significant P value <0.05. It is concluded that TPO 2173A>C polymorphism may be considered as a risk factor for developing autoimmune thyroiditis in patients with allergic rhinitis and asthma and that these patients should regularly be checked for hidden thyroiditis.

Environmental and lifestyle factors such as breast-feeding and pets seem to affect atopic disease prevalence. We identified risk factors for allergic diseases. We prospectively followed until the age of 5 years a cohort of 1,223 children born into allergic families, who participated in a randomized placebo-controlled trial of probiotics as preventive against allergic disease. We evaluated the cumulative incidence of allergic diseases with questionnaires and examined all children at the ages of 2 and 5 years. Compared to allergy in one parent only, allergy in both parents conferred an increased risk of allergic disease at the ages of 2 (OR 1.64; 95% CI 1.11-2.42, p = 0.013) and 5 (OR 1.83; 95% CI 1.24-2.70, p = 0.002) and at the age of 2 for eczema (OR 1.74; 95% CI 1.17-2.58, p = 0.006). Exclusive breast-feeding over 2 months elevated the risk of eczema at the ages of 2 (OR 1.73; 95% CI 1.15-2.61, p = 0.009) and 5 (OR 1.51; 95% CI 1.03-2.23, p = 0.036). Cat or dog exposure at 0-2 years and at 0-5 years protected against IgE sensitization until 5 years of age (OR 0.60; 95% CI 0.37-1.00, p = 0.048, and OR 0.61; 95% CI 0.39-0.96, p = 0.033), and exposure at the ages of 0-5 years protected against allergic rhinitis until the age of 5 (OR 0.46; 95% CI 0.25-0.85, p = 0.013) in the probiotic group. Allergy in both parents is an independent predictor of eczema and of allergic disease until the ages of 2 and 5. Long, exclusive breast-feeding was associated with increased eczema at the ages of 2 and 5, and cat or dog exposure was associated with decreased IgE sensitization and allergic rhinitis in the probiotic group.

The aim of this study was to evaluate the efficacy and effectiveness of homeopathic intervention in the treatment of seasonal or perennial allergic rhinitis (AR). Randomized controlled trials evaluating all forms of homeopathic treatment for AR were included in a systematic review (SR) of studies published up to and including December 2015. Two authors independently screened potential studies, extracted data, and assessed risk of bias. Primary outcomes included symptom improvement and total quality-of-life score. Treatment effect size was quantified as mean difference (continuous data), or by risk ratio (RR) and odds ratio (dichotomous data), with 95% confidence intervals (CI). Meta-analysis was performed after assessing heterogeneity and risk of bias. Eleven studies were eligible for SR. All trials were placebo-controlled except one. Six trials used the treatment approach known as isopathy, but they were unsuitable for meta-analysis due to problems of heterogeneity and data extraction. The overall standard of methods and reporting was poor: 8/11 trials were assessed as "high risk of bias"; only one trial, on isopathy for seasonal AR, possessed reliable evidence. Three trials of variable quality (all using Galphimia glauca for seasonal AR) were included in the meta-analysis: nasal symptom relief at 2 and 4 weeks (RR = 1.48 [95% CI 1.24-1.77] and 1.27 [95% CI 1.10-1.46], respectively) favored homeopathy compared with placebo; ocular symptom relief at 2 and 4 weeks also favored homeopathy (RR = 1.55 [95% CI 1.33-1.80] and 1.37 [95% CI 1.21-1.56], respectively). The single trial with reliable evidence had a small positive treatment effect without statistical significance. A homeopathic and a conventional nasal spray produced equivalent improvements in nasal and ocular symptoms. The low or uncertain overall quality of the evidence warrants caution in drawing firm conclusions about intervention effects. Use of either Galphimia glauca or a homeopathic nasal spray

The aim of this study was to compare the prescription patterns according to characteristics of physicians using a survey distributed amongst physicians in Korea. We surveyed the prescription patterns for allergic rhinitis (AR) of the members of the Korean Academy of Asthma, Allergy and Clinical Immunology (KAAACI) and the Korean Association of Otorhinolaryngologists (KAO). Questionnaire contained 4 categories with 28 queries. 448 physicians including 98 internal medicine (IM), 113 pediatrics (PED), and 237 otorhinolaryngology (ENT) were responded. Although the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines are most frequently used in all specialties, seasonal or perennial AR is the most frequent classification system. For the definitive diagnosis of AR, ENT physicians reported using multiple allergen simultaneous test (MAST)/radio allergy sorbent test (RAST) more than others (IM, 10.9%; PED, 20.6%; ENT, 44.2%; P<0.001). In treatment, most physicians reported that antihistamine medication is the initial treatment for AR. PED physicians prescribed fewer intranasal steroid to combinations with an antihistamine than other specialists (IM, 65.3%; PED, 42.5%; ENT, 63.3%), but preferred leukotriene antagonists (IM, 4.1%; PED, 23.0%; ENT, 3.9%; P=0.041). Overall, 53% (235/448) of the physicians performed allergen immunotherapy (AIT), and IM administers the most AIT (IM, 71.6%; PED, 42.0%; ENT, 39.5%; P=0.019). Furthermore, university and general hospital physicians prescribed more AIT than doctors at other hospital types (university hospital, 76.4%; general hospital, 64.3%; local hospital, 21.4%; private clinic, 20.2%; P<0.001). The prescription patterns for AR were different according to the physicians' characteristics and general rate of prescribing AIT is just about 53% in Korea. Thus, the development of complementary Korean-specific guidelines is needed and proper clinical instruction of AIT would be necessary.

Allergic rhinitis, also known as hay fever, rose fever or summer catarrh, is a major challenge to health professionals. A large number of the world's population, including approximately 40 million Americans, suffers from allergic rhinitis. A novel, botanical formulation (Aller-7) has been developed for the treatment of allergic rhinitis using a combination of extracts from seven medicinal plants, including Phyllanthus emblica, Terminalia chebula, T. bellerica, Albizia lebbeck, Piper nigrum, Zingiber officinale and P. longum, which have a proven history of efficacy and health benefits. The clinical manifestations of allergy are due to a number of mediators that are released from mast cells. The effect of Aller-7 on rat mesenteric mast cell degranulation was studied by incubating different concentrations of Aller-7 and challenging them with a degranulating agent, compound 48/80. The inhibitory activity of Aller-7 was determined against lipoxygenase and hyaluronidase, the key enzymes involved in the initiation and maintenance of inflammatory responses. Furthermore, most of these manifestations are due to histamine, which causes vasodilatation, increasing capillary permeability and leading to bronchoconstriction. Hence, the antihistaminic activity of Aller-7 was determined is isolated guinea pig ileum substrate using cetirizine as a positive control. The antispasmodic effect of Aller-7 on contractions of guinea pig tracheal chain was determined using papaverine and cetirizine as controls. Aller-7 exhibited potent activity in all these in vitro models tested, thus demonstrating the novel anti-allergic potential of Aller-7.

Pollen exposure has acute adverse effects on sensitized individuals. Information on the prevalence of respiratory diseases in areas with different pollen concentrations is scanty. We performed an ecologic analysis to assess whether the prevalence of allergic rhinitis and asthma in young adults varied across areas with different pollen concentrations in Italy. A questionnaire on respiratory diseases was delivered to random samples of 20-44year-old subjects from six centers in 2005-2010. Data on the daily air concentrations of 7 major allergologic pollens (Poaceae, Urticaceae, Oleaceae, Cupressaceae, Coryloideae, Betula and Ambrosia) were collected for 2007-2008. Center-specific pollen exposure indicators were calculated, including the average number of days per year with pollens above the low or high concentration thresholds defined by the Italian Association of Aerobiology. Associations between pollen exposure and disease prevalence, adjusted for potential confounders, were estimated using logistic regression models with center as a random-intercept. Overall, 8834 subjects (56.8%) filled in the questionnaire. Allergic rhinitis was significantly less frequent in the centers with longer periods with high concentrations of at least one (OR per 10days=0.989, 95%CI: 0.979-0.999) or at least two pollens (OR=0.974, 95%CI: 0.951-0.998); associations with the number of days with at least one (OR=0.988, 95%CI: 0.972-1.004) or at least two (OR=0.985, 95%CI: 0.970-1.001) pollens above the low thresholds were borderline significant. Asthma prevalence was not associated with pollen concentrations. Our study does not support that the prevalence of allergic rhinitis and asthma is greater in centers with higher pollen concentrations. It is not clear whether the observed ecologic associations hold at the individual level. Copyright © 2017 Elsevier B.V. All rights reserved.

Obesity has been associated with higher risk of asthma and asthma severity both in children and adults. However, studies evaluating the relation between obesity and rhinitis have yielded conflicting results. We performed a cross-sectional study of obesity indicators and rhinitis using data from 8165 participants in the 2005-2006 National Health and Nutrition Examination Survey. Allergic rhinitis was defined as physician-diagnosed hay fever or allergy, the presence of symptoms in the past 12 months, and at least 1 positive allergen-specific IgE level. Nonallergic rhinitis was defined as a physician's diagnosis and symptoms but no positive allergen-specific IgE levels. Multivariate regression was used to assess the relationship between obesity and rhinitis in children and adults. In adults, overweight or obesity was associated with increased odds of nonallergic rhinitis (adjusted odds ratio, 1.43; 95% CI, 1.06-1.93; P = .02). Similarly, central obesity was associated with increased odds of nonallergic rhinitis in adults (adjusted odds ratio, 1.61; 95% CI, 1.20-2.16; P < .01). In an analysis stratified by sex, the observed associations were attenuated and became nonstatistically significant in female adults but remained significant in male adults. Overweight, obesity, or central obesity were not associated with allergic rhinitis in adults. In children, central obesity was associated with reduced odds of allergic rhinitis (adjusted odds ratio, 0.35; 95% CI, 0.19-0.64; P < .01). After stratification by sex, this association was similar in female and male children. In adults, obesity is associated with increased odds of nonallergic rhinitis, particularly in male subjects. In children, central obesity is associated with reduced odds of allergic rhinitis, regardless of sex. Copyright © 2016 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc.

A number of epidemiologic studies evaluated the prevalence of allergic rhinitis (AR), but few data are available on its different clinical presentations. We addressed this survey to assess the features of AR in children and adolescents. Thirty-five centers in Italy included 2623 pediatric patients with rhinitis, of whom 2319 suffered from AR, while 304 had other kinds of rhinitis. For each patient a standardized questionnaire was filled in, including ARIA classification, the duration of symptoms, the allergen identified as clinically relevant, the co-morbidities, the kind of treatment, the response to treatment, the satisfaction with the treatment, and the feasibility of allergen immunotherapy (AIT). Of the 2319 patients, 597 (25.7%) had mild intermittent, 701 (30.2%) mild persistent, 174 (7.5%) moderate-severe intermittent, and 773 (33.3%) moderate-severe persistent AR. The allergens most relevant were grass pollen and dust mites. The most frequently used drugs were oral antihistamines (83.1%) and topical corticosteroids (63.5%). The response to treatment was judged as excellent in 13.5%, good in 45.1%, fair in 30.8%, poor in 10%, and very bad in 0.6% of cases. The satisfaction with treatment was judged as very satisfactory in 15.2%, satisfactory in 61.8%, unsatisfactory in 22.4%, and very unsatisfactory in 0.5% of cases. AIT was considered indicated in 53.1% of patients with mild intermittent, 79.2% of moderate-severe intermittent, 72.6% of mild persistent, and 82.7% of moderate-severe persistent AR. The limitation of this study is that the population was not unselected and this prevents epidemiological significance. These results offer confirmation of the adequacy of ARIA guidelines in classifying patients with AR and of the association of severe phenotype with lack of success of drug treatment.

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

Nasal polyps are a common problem that is difficult to diagnose and treat, in part because the cause of nasal polyposis is unknown. Although information on the pathogenesis of polyposis is lacking, there are reports suggesting that a genetic predisposition underlies this disorder. We sought to better understand the basis of nasal polyposis associated with allergic rhinitis. We hypothesize that the expression of unique genes is associated with the nasal polyposis phenotype. We examined 12000 human genes transcribed in the nasal mucosa of patients with allergic rhinitis with and without nasal polyps. Biopsy specimens of the mucosa of patients with and without polyps were obtained after the patients refrained from the use of topical or systemic steroid therapy for 2 weeks. Thirty-four genes were differentially expressed between the patient groups, including those for inflammatory molecules and putative growth factors. The greatest differential expression identified by the array analysis was for a group of genes associated with neoplasia, including mammaglobin, a gene transcribed 12-fold higher in patients with polyps compared with control patients with rhinitis alone. Quantitative RT-PCR confirmed this differential expression and documented that the number of mammaglobin mRNA copies is actually 64-fold greater in tissues of patients with polyps versus control patients. The specificity of mammaglobin protein expression was evaluated by means of immunohistochemistry, which showed specific staining in nasal polyp mucosal goblet cells only in patients with polyps. These data suggest that nasal polyposis involves deregulated cell growth, using gene activation in some ways similar to a neoplasm. In addition, mammaglobin, a gene of unknown function associated with breast neoplasia, might be related to polyp growth.

Allergic rhinitis is a chronic inflammatory disease of nasal mucosa. Previous studies have shown the therapeutic effects of ketotifen eye drops on allergic conjunctivitis and rhinitis patients. This study was designed to compare the effects of ketotifen drops and oral ketotifen pills on symptoms and quality of life in allergic rhinitis patients. In this double-blind randomized clinical trial, patients with mild allergic rhinitis who were referred to the allergy clinic of Baqiyatallah Hospital from March to April 2014 were randomly allocated to 2 groups; the first group received ketotifen drops (1 drop every 12 hours) with placebo pills (2 pills daily), and the second group received placebo eye drops with ketotifen pills for 4 weeks. Symptoms (sneezing, runny nose, itching, and nasal obstruction) severity were examined and Rhinitis Quality of Life Questionnaire (RQLQ) scores were evaluated in the second and fourth weeks. A total of 140 patients were evaluated in 2 groups. The mean age was 30.33 years. There were no significant differences in demographic data between the groups (p > 0.05). Both groups showed a significant improvement in rhinorrhea, nasal congestion, nasal itching, coughing, sneezing, RQLQ, and nasal smear eosinophil percent compared to baseline amounts (p < 0.05). Improvements were significantly more in the drops group (p < 0.05). Because of the absence of systemic complications in ketotifen eye drops in patients with allergic rhinitis and their easy availability in Iran, using this medication instead of systemic therapies is suggested. Nevertheless, more studies are required to evaluate the long-term effects of using this drug and the recurrence rate of symptoms. © 2015 ARS-AAOA, LLC.

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.

To assess the prevalence of allergic rhinitis symptoms among schoolchildren in Mexicali, Baja California, Mexico, and determine what impact a rural environment might have on this condition. A population-based, cross-sectional study using a standardized questionnaire administered to a random sample of 2087 schoolchildren 6-7 years of age (1078 girls and 1009 boys) living in the city of Mexicali, Baja California, Mexico. The study analyzed associations between exposure variables and personal and family health history, and two dependent variables-nasal symptoms and nasal and ocular symptoms, in the absence of a cold or flu-using odd ratios (OR) and 95% Confidence Intervals (95%CI). The study took place in February-July 2004 and followed the methodology of the International Study of Asthma and Allergies in Childhood (ISAAC). The general prevalence of nasal symptoms and nasal and ocular symptoms was 25.0% and 10.5%, respectively. The boys and girls who had ever lived on a farm or in a rural area had a lower probability, adjusted for confounding variables, of presenting nasal symptoms (OR=0.43; 95%CI: 0.24-0.77), or nasal and ocular symptoms (OR=0.39; 95%CI: 0.16-0.93). In the study population, exposure to a rural environment in early childhood decreased the risk of developing allergic rhinitis, regardless of a family history of asthma.

Allergic rhinitis is an inflammatory disease of the nasal mucosa, caused by an IgE-mediated reaction after exposure to the allergen to which the patient is sensitized. Histamine is the most important preformed mediator released in the early stage of the allergic reaction, and also contributes to the late phase of the latter, exhibiting proinflammatory effects. Minimal persistent inflammation is a physiopathological phenomenon induced by the presence of an inflammatory cell infiltrate, together with ICAM-1 expression in the epithelial cells of the mucosa exposed to the allergen to which they are sensitized, in the absence of clinical symptoms. This molecule is considered to be an allergic inflammatory marker. The priming effect first described by Connell in 1968 consists of the reduction in the allergen concentration required to elicit a nasal hyper-response when performing a daily nasal exposure test. This implies that with natural exposure to inhaled allergens, small amounts of environmental allergen will maintain the patient symptoms, and thus of course minimal persistent inflammation. Considering the above, it is questionable whether antihistamines should be administered on a continuous basis or upon demand. The antihistamines, and fundamentally the second-generation drugs, have been shown to exert an antiinflammatory effect, and this effect is greater when the drug is administered continuously than when administered upon demand. Likewise, a reduction in treatment cost and an improvement in quality of life among patients treated on a continuous basis has been documented. However, no studies have been specifically designed to clarify the indication of treatment on a continuous basis or upon demand, as occurs in the GINA. As a result, the individualization of treatment according to the concrete characteristics of each patient seems to be the best approach, at least for the time being.

Taking medical history, physical examination, and performing some in vivo and in vitro tests are necessary for the diagnosis of allergy. Skin prick test (SPT) is considered as the standard method and first-line approach for the detection of allergic sensitization. Although mainly SPT is used for the detection of allergic sensitization, intradermal skin test (IDST) may be necessary, especially in patients with a negative SPT result. IDST is quite safe; however, is nowadays seldom used for detection of inhalant allergy and its value remains controversial. We aimed to investigate whether IDST is useful and necessary in diagnosis of respiratory allergies or not. This study involved 4223 patients with allergic rhinitis (AR) and/or bronchial asthma (BA). SPT results were positive in 2419 patients (57%) and negative in 1804 (43%). IDST was applied to 344 patients with marked allergic symptoms and with negative SPT results. Out of 344 patients, 152 (44%) showed allergic sensitization to IDST. The most commonly encountered allergic response was against the house dust mite (HDM) (32.6%). Allergic response against fungal spores was also relatively high (22%), while the pollen allergy rate (4.3%) was quite low. In BA patients with negative prick test, IDST made a significant contribution to the diagnosis of HDM allergy (p=0.003). To avoid missed diagnosis of AR and BA, particularly regarding  the HDM allergy, application of IDST may be beneficial; therefore, IDST should be considered as the next step after SPT for diagnosis of allergy prior to in vitro or provocation tests.

The Atopic March: Progression from Atopic Dermatitis to Allergic Rhinitis and Asthma

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.

Allergic rhinitis-induced nasal congestion: its impact on sleep quality.

PubMed

Storms, William

2008-03-01

Allergic rhinitis (AR) is an extremely common health problem affecting 20 to 40 million Americans and between 10-25% of the world's population. Patients with AR suffer from both nasal symptoms (congestion, rhinorrhea, itching, and sneezing) and ocular symptoms (itching, redness, and tearing). The negative impact on sleep quality and quantity, and consequently on various aspects of the patient's life, is an under-recognised and under-treated component of AR morbidity. Nasal congestion, which is one of the most bothersome and prevalent symptoms of AR, is thought to be the leading symptom responsible for rhinitis-related sleep problems. In addition to reducing clinical symptoms, pharmacologic therapies for AR that specifically reduce inflammatory cells and mediators - and therefore nasal congestion and other symptoms - should also improve sleep quality and overall quality of life (QOL). Intranasal corticosteroids (INS) are the current mainstay of therapy for AR. Results of a number of clinical trials demonstrate that INS effectively reduce nasal congestion and ocular symptoms, improve sleep quality, and decrease daytime somnolence. Intranasal corticosteroids have also proved to be effective in reducing symptoms of acute rhinosinusitis and nasal polyposis, both of which also negatively impact on sleep quality. Intranasal corticosteroids are considered safe due to their low systemic bioavailability.

Allergic rhinitis (AR) is a multifactorial disease characterized by paroxysmal symptoms of sneezing, rhinorrhea, postnasal drip and nasal congestion. For over a century, subcutaneous allergen immunotherapy (SCIT) has been recognized as the most effective therapy to date that may modify the underlying disease course and provide long-term benefits for individuals refractory to pharmacotherapy. However, over the past 25 years, there has been substantial growth in developing alternative therapies to traditional SCIT. Areas covered: This article will review the most current literature focusing on advancements of AR therapies. Novel AR therapies that are currently under investigation include: the addition of omalizumab, an anti-immunoglobulin E (IgE) monoclonal antibody (mAb), to SCIT; altering the method of delivery of allergen immunotherapy (AIT) including sublingual (SLIT), epicutaneous (EIT), intralymphatic (ILIT), intranasal (INIT) and oral mucosal immunotherapy (OMIT); use of capsaicin spray; novel H3 and H4 antihistamines; activation of the innate immune system through Toll-like receptor agonists; and the use of chemically altered allergens, allergoids, recombinant allergens and relevant T-cell epitope peptides to improve the efficacy and safety of AIT. Expert opinion: These promising novel therapies may offer more effective and/or safer treatment options for AR patients, and in some instances, induce immunologic tolerance.

Abstract Each year more than 50 million Americans suffer from allergic rhinitis, which is a state of hypersensitivity or hyperimmunity. Basically, allergic rhinitis is symptomatically recognized as the inflammation and irritation of the nasal mucosal membranes; sneezing; stuffy/runny nose; nasal congestion; and itchy; watery, and swollen eyes; and defined as a state of hypersensitivity/ hyperimmunity caused by exposure to a particular allergen (antigen) that results in increased reactivity upon subsequent exposure. A novel polyherbal formulation (Aller-7/NR-A2) was 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. Earlier studies in our laboratories have demonstrated potent antihistaminic, anti-inflammatory, antispasmodic, antioxidant, and mast-cell stabilization activities of Aller-7 in addition to its efficacy in a clinical setting. A series of preliminary toxicological evaluations were also conducted in the past, which demonstrated its safety. In this study, we have conducted further safety studies on Aller-7, including acute oral, acute dermal, acute dermal irritation, eye irritation, and 90-day repeated dose toxicity studies. Acute oral toxicity of Aller-7 was found to be greater than 5,000 mg/kg body weight in both male and female rats and no mortality or toxicity was observed at this dose, while the acute dermal toxicity was found to be greater than 2,000 mg/kg body weight. In the acute dermal irritation study, the skin irritancy index was found to be 0.0, which classifies Aller-7 as a nonirritant to rabbit skin. In the acute eye irritation study, Aller-7 was found to have minimal irritancy to eyes of rabbits. In the repeated-dose 90-day oral toxicity study, Aller-7 was administered at dose levels of 100, 300, and 1,000 mg/kg rat body weight for 90

Background An association between chronic rhinosinusitis (CRS) and gastroesophageal reflux disease (GERD) has been previously reported; however, the underlying factors linking CRS and GERD remain to be elucidated. Objective To assess the association of GERD and CRS using prospective and retrospective approaches. Methods The retrospective study comprised a large cohort of CRS cases, whereas the prospective arm evaluated a series of CRS cases and controls. Results In the retrospective arm of the study, of the 1066 patients with CRS, 112 (10.5%) had GERD. Among patients with CRS, GERD was associated with higher body mass index, older age, and female sex. The odds ratios (ORs) for asthma and allergic rhinitis in the CRS group with GERD compared with the CRS group without GERD were 2.89 (95% confidence interval [CI], 1.905–4.389) and 2.021 (95% CI, 1.035–3.947). Furthermore, GERD was associated with a greater duration of CRS. Ninety patients with CRS and 81 controls were enrolled in the prospective arm of the study. In the CRS group, GERD was associated with asthma (OR, 4.77; 95% CI, 1.27–18.01). Patients with CRS and GERD had a longer duration and a younger age at onset of CRS. In controls, no association was found between GERD and asthma (OR, 0.67; 95% CI, 0.09–5.19) or allergic rhinitis (OR, 0.35; 95% CI, 0.05–2.59). Conclusion Patients with CRS and GERD are more likely to have atopic conditions and asthma when compared with patients with CRS but without GERD. One of the potential explanations of this link is that comorbid GERD and atopic disease are potential risk factors for development of CRS. PMID:27283453

The burden of allergic rhinitis.

PubMed

Nathan, Robert A

2007-01-01

Although formerly regarded as a nuisance disease, allergic rhinitis (AR) has a considerable effect on quality of life and can have significant consequences if left untreated. The total burden of this disease lies not only in impaired physical and social functioning but also in a financial burden made greater when considering evidence that AR is a possible causal factor in comorbid diseases such as asthma or sinusitis. Compared with matched controls, patients with AR have an approximate twofold increase in medication costs and 1.8-fold the number of visits to health practitioners. Hidden direct costs include the treatment of comorbid asthma, chronic sinusitis, otitis media, upper respiratory infection, and nasal polyposis. Nasal congestion, the most prominent symptom in AR, is associated with sleep-disordered breathing, a condition that can have a profound effect on mental health, including increased psychiatric disorders, depression, anxiety, and alcohol abuse. Furthermore, sleep-disordered breathing in childhood and adolescence is associated with increased disorders of learning performance, behavior, and attention. In the United States, AR results in 3.5 million lost workdays and 2 million lost schooldays annually. Patients struggle to alleviate their misery, frequently self-adjusting their treatment regimen of over-the-counter and prescription medications because of lack of efficacy, deterioration of efficacy, lack of 24-hour relief, and bothersome side effects. Ironically, health care providers overestimate patient satisfaction with therapy. Therefore, improvement in patient-practitioner communication may enhance patient adherence with prescribed regimens.

Background The mechanisms explaining the co-existence of asthma, eczema and rhinitis (allergic multimorbidity) are largely unknown. We investigated the mechanisms underlying multimorbidity between three main allergic diseases at a molecular level by identifying the proteins and cellular processes that are common to them. Methods An in silico study based on computational analysis of the topology of the protein interaction network was performed in order to characterize the molecular mechanisms of multimorbidity of asthma, eczema and rhinitis. As a first step, proteins associated to either disease were identified using data mining approaches, and their overlap was calculated. Secondly, a functional interaction network was built, allowing to identify cellular pathways involved in allergic multimorbidity. Finally, a network-based algorithm generated a ranked list of newly predicted multimorbidity-associated proteins. Results Asthma, eczema and rhinitis shared a larger number of associated proteins than expected by chance, and their associated proteins exhibited a significant degree of interconnectedness in the interaction network. There were 15 pathways involved in the multimorbidity of asthma, eczema and rhinitis, including IL4 signaling and GATA3-related pathways. A number of proteins potentially associated to these multimorbidity processes were also obtained. Conclusions These results strongly support the existence of an allergic multimorbidity cluster between asthma, eczema and rhinitis, and suggest that type 2 signaling pathways represent a relevant multimorbidity mechanism of allergic diseases. Furthermore, we identified new candidates contributing to multimorbidity that may assist in identifying new targets for multimorbid allergic diseases. PMID:28598986

Allergic rhinitis and inflammatory airway disease: interactions within the unified airspace.

PubMed

Marple, Bradley F

2010-01-01

Allergic rhinitis (AR), the most common chronic allergic condition in outpatient medicine, is associated with immense health care costs and socioeconomic consequences. AR's impact may be partly from interacting of respiratory conditions via allergic inflammation. This study was designed to review potential interactive mechanisms of AR and associated conditions and consider the relevance of a bidirectional "unified airway" respiratory inflammation model on diagnosis and treatment of inflammatory airway disease. MEDLINE was searched for pathophysiology and pathophysiological and epidemiologic links between AR and diseases of the sinuses, lungs, middle ear, and nasopharynx. Allergic-related inflammatory responses or neural and systemic processes fostering inflammatory changes distant from initial allergen provocation may link AR and comorbidities. Treating AR may benefit associated respiratory tract comorbidities. Besides improving AR outcomes, treatment inhibiting eosinophil recruitment and migration, normalizing cytokine profiles, and reducing asthma-associated health care use in atopic subjects would likely ameliorate other upper airway diseases such as acute rhinosinusitis, chronic rhinosinusitis (CRS) with nasal polyposis (NP), adenoidal hypertrophy, and otitis media with effusion. Epidemiological concordance of AR with several airway diseases conforms to a bidirectional "unified airway" respiratory inflammation model based on anatomic and histological upper and lower airway connections. Epidemiology and current understanding of inflammatory, humoral, and neural processes make links between AR and disorders including asthma, otitis media, NP, and CRS plausible. Combining AR with associated conditions increases disease burden; worsened associated illness may accompany worsened AR. AR pharmacotherapies include antihistamines, leukotriene antagonists, intranasal corticosteroids, and immunotherapy; treatments attenuating proinflammatory responses may also benefit

: To determine the effectiveness of desloratadine syrup in relieving symptoms of allergic rhinitis (AR) among children in Latin America. : In an open-label trial conducted in 5 Latin American countries, 455 children aged 6 to 12 years with seasonal or perennial AR were treated with desloratadine syrup 2.5 mg/d for 6 weeks. Thirty percent of subjects were concomitantly taking corticosteroids, and 21.3% had a history of asthma. Efficacy was measured by improvement in the Total Symptom Severity 4 questionnaire and decrease in severity of individual nasal symptoms of congestion, rhinorrhea, pruritus, and sneezing. Physicians and subjects' caregivers rated symptom improvement in a separate assessment at final visit. : Treatment with desloratadine led to a significant decrease in mean Total Symptom Severity 4 score, from 7.54 at baseline to 1.96 at study end (P < 0.0001), and in individual symptom scores, including congestion (P < 0.0001 for all). Similar improvements were found in groups receiving desloratadine monotherapy and desloratadine plus corticosteroids. Allergic rhinitis symptoms were rated "better" or "much better" by 94% of caregivers. Incidence of adverse events was 6%. : Desloratadine, with or without concomitant corticosteroids, was efficacious and safe in the treatment of AR in this group of Latin American children.

Data comparing the treatment effect of allergy immunotherapy and pharmacotherapy are lacking. We sought to indirectly compare the treatment effect of sublingual immunotherapy (SLIT)-tablets with pharmacotherapy for seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR). Pooled data from randomized, double-blind, placebo-controlled trials for the clinical development programs of selected allergic rhinitis treatments were evaluated. Total nasal symptom scores (TNSSs) relative to placebo were compared. Subjects scored symptoms daily during entire pollen seasons in 6 timothy grass SLIT-tablet trials (n = 3094) and 2 ragweed SLIT-tablet trials (n = 658) and during the last 8 weeks of treatment in 2 house dust mite (HDM) SLIT-tablet trials (n = 1768). Subjects scored symptoms daily in 7 montelukast (10 mg, n = 6799), 9 desloratadine (5 mg, n = 4455), and 8 mometasone furoate nasal spray (MFNS; 200 μg daily, n = 2140) SAR or PAR trials. SLIT-tablet trials allowed rescue medication use, whereas most pharmacotherapy trials did not. A fixed-effect meta-analysis method estimated differences in on-treatment average TNSSs. In grass and ragweed SLIT-tablet trials, overall improvement in TNSSs relative to placebo was 16.3% and 17.1%, respectively. In HDM SLIT-tablet trials, TNSS overall improvement relative to placebo was 16.1%. In the montelukast, desloratadine, and MFNS trials, TNSS overall improvement relative to placebo was 5.4%, 8.5%, and 22.2%, respectively, for SAR trials, and 3.7%, 4.8%, and 11.2%, respectively, for PAR trials. Although comparisons were limited by study design heterogeneity and use of rescue medications in SLIT-tablet trials, effects on nasal symptoms with timothy grass and ragweed SLIT-tablets were nearly as great as with MFNS and numerically greater than with montelukast and desloratadine for SAR. HDM SLIT-tablet effects were numerically greater than all pharmacotherapies for PAR. SLIT-tablets offer the additional

Perennial allergic rhinitis is chronic and persistent, may lead to a constellation of secondary complaints including sinusitis, mouth-breathing, and some symptoms resembling a permanent cold, and often requires constant medical intervention. Well-tolerated nasal corticosteroids, alone or in combination with antihistamines, have been found to be very effective in treating this condition. To compare the effectiveness and tolerability of mometasone furoate aqueous suspension, a new once daily nasal spray, to placebo vehicle and to beclomethasone dipropionate, administered twice daily, in patients with perennial allergic rhinitis. This was a randomized, double-blind, placebo-controlled, double-dummy, parallel group study, in 427 patients age 12 years and older at 24 centers in Canada and Europe. Patients allergic to at least one perennial allergen, confirmed by medical history, skin testing, and adequate symptomatology were eligible to receive one of the following regimens for 3 months: mometasone furoate, 200 micrograms only daily; beclomethasone dipropionate, 200 micrograms twice daily (400 micrograms total dose); or placebo vehicle control. The primary efficacy variable was the change from baseline in total AM plus PM diary nasal symptom score over the first 15 days of treatment. Three hundred eighty-seven patients were valid for efficacy. For the primary efficacy variable, mometasone furoate was significantly (P < or = .01) more effective than placebo and was indistinguishable from beclomethasone dipropionate. Similar trends were seen among individual symptoms, physician symptom evaluations, and therapeutic response. There was no evidence of tachyphylaxis. All treatments were well tolerated. Mometasone furoate nasal spray adequately controls symptoms of perennial allergic rhinitis, offers the advantage of once daily treatment, and is well tolerated.

Clinical outcomes and adverse effect monitoring in allergic rhinitis.

The subjective recording in diary cards of symptoms of itch, sneeze, nose running, and blockage, with the use of a rating scale to indicate the level of severity, is usual for clinical trials in allergic rhinitis. The primary outcome measure is usually a composite score that enables a single total symptoms score endpoint. It is appreciated, however, that rhinitis has a greater effect on the individual than is reflected purely by the recording of anterior nasal symptoms. Nasal obstruction is troublesome and may lead to sleep disturbance in addition to impaired daytime concentration and daytime sleepiness. These impairments affect school and work performance. Individuals with rhinitis find it socially embarrassing to be seen sneezing, sniffing, or blowing their nose. To capture these and other aspects of the disease-specific health-related quality of life, questionnaires such as the Rhinoconjunctivitis Quality of Life Questionnaire have been developed and validated for clinical trial use. The adoption of health-related quality of life questionnaires into clinical trials broadens the information obtained regarding the effect of the therapeutic intervention and helps focus on issues relevant to the individual patient. It must be appreciated that it is not only the disease that may adversely affect health-related quality of life; administered therapy, although intended to be beneficial, may also cause health impairment. Adverse-event monitoring is thus essential in clinical trials. The first-generation H 1 -histamines, because of their effect on central H 1 -receptors, are classically associated with central nervous system (CNS) effects such as sedation. Although this is not always perceived by the patient, it is clearly evident with objective performance testing, and positron emission tomography scanning has directly demonstrated the central H 1 -receptor occupancy. The second-generation H 1 -antihistamines have reduced central H 1 -receptor occupancy and considerably

Exclusive breast-feeding (EBF) seems to reduce risk of allergies in the western countries, but there are few reports from developing countries. The purpose of this study was to assess the effect of EBF on the development of allergic diseases and eczema in a developing country. This is a cross-sectional survey done at the well-baby clinics of 11 primary health centers, Hamad Medical Corporation, Qatar. A multistage sampling design was used and a representative sample of 1500 children (0-5 years old) and mothers (18-47 years old) were surveyed between October 2006 and September 2007. Of them, 1278 mothers (85.2%) participated in the study. A confidential, anonymous questionnaire assessing breast-feeding and allergic diseases was completed by mothers bringing children for immunization. Questionnaire included allergic rhinitis, wheezing, eczema, type and duration of breast-feeding, parental smoking habits, number of siblings, family income, maternal education, and parental allergies. Univariate and multivariate statistical methods were performed for statistical analysis. More than one-half of the infants (59.3%) were on EBF. Length of breast-feeding was associated with maternal age. Prevalence of eczema (19.4%), allergic rhinitis (22.6%), and wheezing (12.7%) were significantly less frequent in those with prolonged (>6 months) compared with short-term fed infants. The association between EBF and eczema tended to be similar in children with a positive family history of atopy (p < 0.001) and eczema (p < 0.001) compared with those without. In children of developing countries, prolonged breast-feeding reduces the risk of developing allergic diseases and eczema even in the presence of maternal allergy, where it might be a practical, effective preventive measure.

To investigate the psychological status of Chinese adults with seasonal allergic rhinitis (SAR) in the allergic season, and evaluate the effects of nasal symptoms on their psychological status. The Symptom Checklist 90 (SCL-90) or Self-Reporting Inventory was employed to analyze the psychological status of 337 SAR patients. The SCL-90 scores of the SAR patients were statistically higher than those of nonallergic adults in terms of somatization, depression, anxiety, hostility and psychosis. No statistical discrepancies existed in gender or age, the impact of disease course was limited to somatization, compulsion and phobic disorders and the impact of the educational level was that the lower the level of education, the more obvious the hostility. The behavior of somatization, compulsion, depression and anxiety in patients with a history of eczema or asthma was much more obvious than in patients without such a history. Nasal obstruction had a conspicuous impact on somatization, compulsion, interpersonal sensitivity, depression, anxiety and psychosis, while nasal itching contributed to somatization, depression and anxiety. The psychological status of SAR patients is evidently worse than that of nonallergic adults. Symptoms such as nasal obstruction and nasal itching had an obvious impact on the psychological status of the patients. Copyright 2010 S. Karger AG, Basel.

Allergic rhinitis (AR) is a common health problem in the United States, with significant comorbidities and impairment of quality of life despite the availability of many prescription (Rx) and over-the-counter (OTC) medications. The health-care practitioners (HCPs) arm of the Current Allergic Rhinitis Experiences Survey (CARES) assessed HCPs' perceptions about the current management of AR. This U.S.-based national survey included 375 primary care physicians and 375 nurse practitioners/physician assistants. Participants were screened to ensure that they treat ≥15 AR sufferers per month during allergy season. The majority of HCPs (86%) agreed that AR patients can easily recognize allergy symptoms after diagnosis and that 57% of their patients come to them self-recognizing their symptoms. A total of 82% strongly agreed that AR sufferers are primarily diagnosed via history and physical and do not typically undergo diagnostic testing until after pharmacologic intervention. HCPs reported that 63-77% of AR sufferers can easily manage AR once treatment is established. According to surveyed HCPs, OTC medication should precede an Rx medication for AR management. A total of 82% HCPs considered intranasal steroids (INSs) to be the gold standard AR treatment and have minimal safety concerns about INS use. HCPs perceive that patients can easily recognize and self-manage their AR symptoms. Patient history/symptoms and physical examination are the primary methods of AR diagnosis. INSs are considered the gold standard for treatment of AR. However, most HCPs feel OTC medication should be tried before Rx medication for AR management.

To analyze the compliance of sublingual desensitization used in allergic rhinitis patients by telephone follow up, and to discuss the influencing factor associate with medicine pause. One hundred and thirty-two patients of allergic rhinitis were randomly divided into two groups, 53 cases was in the control group, 79 cases was in telephone follow up group for a period of 6 months of observation. Sublingual desensitization treatment for 6 months, 28/53 cases of control group were compliance, 25/53 cases were loss, and compliance rate was 52.8%; 17/27 cases of follow-up group A were compliance, 10/27 cases were loss, and compliance rate was 63.0%; 21/28 cases of follow-up group B were compliance, 7/28 cases were loss, and compliance rate was 75.0%; 22/24 of follow-up group C were compliance, 2/24 cases were loss, and compliance rate was 91.7% (P < 0.05). Significant difference was found in the 4th month after treatment (P < 0.01). Long-term treatment and cure were the main impact factors for compliance. Timely telephone follow-up education and guidance to patients could improve compliance of patients with sublingual desensitization.

Allergic rhinitis (AR) is a common allergic disorder in children, some of whom seek complementary treatments, including acupuncture and Chinese herbs. Little, however, is known about the treatment of pediatric AR with traditional Chinese medicine (TCM). To characterize TCM use in pediatric AR, we conducted a nationwide population-based study. We screened one million randomly sampled beneficiaries of the National Health Insurance Program in Taiwan from 2002 to 2010 to identify children <18 years of age with newly diagnosed allergic rhinitis (ICD-9 code 477.9). The subjects were categorized according to their use of TCM. We identified 97,401 children newly diagnosed with AR for inclusion in the study. Among these children, 63.11% (N=61,472) had used TCM. There were significantly more TCM users than non-users among school-age children and adolescents (P<0.001). Most (99.1%) pediatric TCM users received Chinese herbal remedies (99.1%); only 0.9% received acupuncture or manipulative therapies. Xin-Yi-Qing-Fei-Tang (Magnolia Flower Lung-Clearing Decoction) was the most frequently prescribed TCM formulation (23.44%), and the most commonly prescribed single herb was Chan-Tui (Periostracum cicadae; 13.78%). Regarding syndrome differentiation (ZHENG) according to TCM theory, prescriptions for the Cold Syndrome exceeded those for the Hot Syndrome throughout the year in Taiwan. We found that approximately two-thirds of pediatric AR patients were prescribed TCM treatments in Taiwan. Further research is warranted to examine the efficacy and safety of TCM for pediatric AR patients. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Filaggrin loss-of-function (FLG-LOF) mutations are an established genetic cause of eczema. These mutations have subsequently been reported to increase the risk of aeroallergen sensitization and allergic airway disease. However, it is unclear whether FLG variants require both eczema and aeroallergen sensitization to influence airway disease development long-term outcomes. To examine the effects of FLG-LOF mutations on allergic airway disease outcomes, with eczema and aeroallergen sensitization as intermediate variables, using the Isle of Wight birth cohort. Study participants were evaluated at ages 1, 2, 4, 10 and 18 years to ascertain the development of allergic diseases (eczema, asthma and allergic rhinitis) and aeroallergen sensitization (determined by skin prick tests). FLG-LOF mutations were genotyped in 1150 subjects. To understand the complex associations between FLG mutations, intermediate variables (eczema and aeroallergen sensitization) and airway disease, path analysis was performed. There were significant total effects of FLG-LOF mutations on both asthma and allergic rhinitis at all ages as well as on aeroallergen sensitization up till 10 years old. In the filaggrin-asthma analysis, a direct effect of FLG-LOF mutations was observed on early childhood eczema (age 1 and 2 years) (relative risk (RR) 2.01, 95% CI: 1.74-2.31, P < .001), and all significant indirect pathways on asthma outcomes passed through eczema at these ages. In contrast, for the filaggrin-rhinitis model, FLG-LOF mutations exerted significant direct effects on early eczema as well as rhinitis at 10 years (RR 1.99; 95% CI: 1.72-2.29, P = .002). FLG-LOF mutations are a significant risk factor for later childhood asthma and rhinitis. However, the pathway to asthma is only through early childhood eczema while a direct effect was observed for childhood rhinitis. © 2017 John Wiley & Sons Ltd.

The relationships between atopy, rhinitis and asthma: pathophysiological considerations.

PubMed

Boulay, Marie-Eve; Boulet, Louis-Philippe

2003-02-01

A close relationship has been described between atopy, allergic rhinitis and asthma. The purpose of this work was to review recent data that have become available on the interactions between these conditions and the ways in which they influence one another. Recent findings support previous observations suggesting that atopic dermatitis and rhinitis often accompany or precede the development of asthma. Further data support the notion that early-life exposure to domestic animals, a farming environment, passive smoking, and being raised in a large family, may be protective against the development of atopy and/or allergic diseases, although this seems modulated by genetic factors. Furthermore, the appearance of house-dust-mite-specific immunoglobulin E antibodies in early childhood has been identified as a major risk factor for the development of asthma in children with atopic dermatitis; and the association between sensitization to specific allergens and airway hyperresponsiveness was reported to be the strongest for indoor allergens such as house-dust-mite and cat. Allergen exposure can increase airway responsiveness in non-asthmatic subjects with allergic rhinitis and is associated with an increase in markers of lower airway inflammation, particularly with indoor allergens. Furthermore, nasal allergen provocation can induce bronchial inflammation and vice versa, suggesting close interrelations between upper and lower airways. In summary, the recent observations on the relationships between atopy, rhinitis and asthma support the hypothesis of a unique systemic condition with variable manifestations, which may develop following an imbalance between T helper cell types 1 and 2 lymphocyte populations. The latter may be influenced by environmental exposure in early life. Upper- and lower-airway inflammatory events influence each other, supporting the concept of 'united airways'. Further studies should look at the relationships between these conditions to identify

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. Randomised, double blind, placebo controlled, parallel group, multicentre study. Four general practices and a hospital ear, nose, and throat outpatient department. 51 patients with perennial allergic rhinitis. Random assignment to an oral 30c homoeopathic preparation of principal inhalant allergen or to placebo. Changes from baseline in nasal inspiratory peak flow and symptom visual analogue scale score over third and fourth weeks after randomisation. 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). The objective results reinforce earlier evidence that homoeopathic dilutions differ from placebo.

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.

The history and progression of treatments for allergic rhinitis.

PubMed

Ostrom, Nancy K

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.

There is a significant genetic contribution to allergic rhinitis (AR). Genetic association studies for AR have been performed, but varying results make it challenging to decipher the overall potential effect of specific variants. The Th2 pathway plays an important role in the immunological development of AR. We performed meta-analyses of genetic association studies of variants in Th2 pathway genes and AR. PubMed and Phenopedia were searched by double extraction for original studies on Th2 pathway-related genetic polymorphisms and their associations with AR. A meta-analysis was conducted on each genetic polymorphism with data meeting our predetermined selection criteria. Analyses were performed using both fixed and random effects models, with stratification by age group, ethnicity, and AR definition where appropriate. Heterogeneity and publication bias were assessed. Six independent studies analyzing three candidate polymorphisms and involving a total of 1596 cases and 2892 controls met our inclusion criteria. Overall, the A allele of IL13 single nucleotide polymorphism (SNP) rs20541 was associated with increased odds of AR (estimated OR=1.2; 95% CI 1.1-1.3, p-value 0.004 in fixed effects model, 95% CI 1.0-1.5, p-value 0.056 in random effects model). The A allele of rs20541 was associated with increased odds of AR in mixed age groups using both fixed effects and random effects modeling. IL13 SNP rs1800925 and IL4R SNP 1801275 did not demonstrate overall associations with AR. We conclude that there is evidence for an overall association between IL13 SNP rs20541 and increased risk of AR, especially in mixed-age populations. © 2011 John Wiley & Sons A/S.

Emerging evidence questions current recommendations on the timing of infant feeding for the prevention of childhood allergies. The evidence for asthma is inconclusive. We sought to investigate the associations between the duration of breast-feeding and timing of introduction of complementary foods and the development of asthma and allergies by the age of 5 years. Data were analyzed for 3781 consecutively born children. The dietary exposures were categorized into thirds and analyzed as time-dependent variables. Asthma, allergic rhinitis, and atopic eczema end points were assessed by using the International Study of Asthma and Allergies in Childhood questionnaire, whereas IgE antibodies were analyzed from serum samples at the age of 5 years. Cox proportional hazard and logistic regressions were used for the analyses. The median duration of exclusive and total breast-feeding was 1.4 months (interquartile range, 0.2-3.5 months) and 7.0 months (interquartile range, 4.0-11.0 months), respectively. Total breast-feeding of 9.5 months or less was associated with an increased risk of nonatopic asthma. Introduction of wheat, rye, oats, or barley at 5 to 5.5 months was inversely associated with asthma and allergic rhinitis, whereas introduction of other cereals at less than 4.5 months increased the risk of atopic eczema. Introduction of egg at 11 months or less was inversely associated with asthma, allergic rhinitis, and atopic sensitization, whereas introduction of fish at 9 months or less was inversely associated with allergic rhinitis and atopic sensitization. Early introduction of wheat, rye, oats, and barley cereals; fish; and egg (respective to the timing of introduction of each food) seems to decrease the risk of asthma, allergic rhinitis, and atopic sensitization in childhood. Longer duration of total breast-feeding, rather than its exclusivity, was protective against the development of nonatopic but not atopic asthma, suggesting a potential differing effect of breast

There is evidence to suggest that atopic disease in adulthood could be manifestations of events in early life. To investigate the relationship between perinatal risk factors and the prevalence of allergic rhinitis and asthma in conscripts. A retrospective cohort study, where information from the Military Service Enrolment Register was linked to the national Medical Birth Register. The study included 149 398 male conscripts who were born in Sweden in 1973, 1974 and 1975. Outcome measures were current asthma and allergic rhinitis recognized at the compulsory military conscript examinations. Unifactorial analyses demonstrated that number of older siblings, young maternal age, multiple gestation, prematurity, low birth weight, growth retardation and perinatal asphyxia were all significantly related to a decreased risk of allergic rhinitis among male conscripts. The prevalence rates of allergic rhinitis among conscripts with and without older siblings were 14.1% and 16.2%, respectively (odds ratio 0.85; 95% confidence interval 0.82-0.87). The prevalence rates of allergic rhinitis among those with term birth (>36 weeks), moderately preterm birth (33-36 weeks) and very preterm birth (<33 weeks) were 15.2%, 13.1% and 11.6%, respectively. Older siblings, multiple gestation and young maternal age were highly significant independent determinants of allergic rhinitis. By contrast, the effects of prematurity, low birthweight and asphyxia were weaker and highly correlated. The only independent determinants of asthma were maternal age, birthweight and multiple gestation. Furthermore, maternal age and birthweight had opposite effects on asthma and allergic rhinitis. In contrast to asthma, allergic rhinitis in young adult men was strongly associated with perinatal events. This may reflect the close relationship between allergic rhinitis and atopic sensitization, whereas asthma has a more multifactorial aetiology.

Allergic rhinitis (AR) is one of the most common diseases affecting adults. It is the most common chronic disease in children in the United States today and the fifth most common chronic disease in the United States overall. AR is estimated to affect nearly 1 in every 6 Americans and generates $2 to $5 billion in direct health expenditures annually. It can impair quality of life and, through loss of work and school attendance, is responsible for as much as $2 to $4 billion in lost productivity annually. Not surprisingly, myriad diagnostic tests and treatments are used in managing this disorder, yet there is considerable variation in their use. This clinical practice guideline was undertaken to optimize the care of patients with AR by addressing quality improvement opportunities through an evaluation of the available evidence and an assessment of the harm-benefit balance of various diagnostic and management options. The primary purpose of this guideline is to address quality improvement opportunities for all clinicians, in any setting, who are likely to manage patients with AR as well as to optimize patient care, promote effective diagnosis and therapy, and reduce harmful or unnecessary variations in care. The guideline is intended to be applicable for both pediatric and adult patients with AR. Children under the age of 2 years were excluded from the clinical practice guideline because rhinitis in this population may be different than in older patients and is not informed by the same evidence base. The guideline is intended to focus on a limited number of quality improvement opportunities deemed most important by the working group and is not intended to be a comprehensive reference for diagnosing and managing AR. The recommendations outlined in the guideline are not intended to represent the standard of care for patient management, nor are the recommendations intended to limit treatment or care provided to individual patients. The development group made a strong

The aim of this study was to determine whether there were differences in health-related quality of life of patients with allergic rhinitis treated with bilastine 20 mg compared to those treated with loratadine 10 mg. This was a prospective randomised double-blinded study. Otolaryngology outpatient clinics in Criciúma, state of Santa Catarina, Brazil. Seventy-three patients, aged between 18 and 63 years, of whom 36 were treated with loratadine 10 mg and 37 with bilastine 20 mg with medication administered once a day for 10 days. The outcome was quality of life as assessed by the modified Rhinoconjunctivitis Quality of Life Questionnaire (RQLQm), which was applied at baseline and after 10 days of treatment. The use of bilastine 20 mg or loratadine 10 mg significantly reduced RQLQm scores after 10 days of treatment (P < 0.001); however, there was no statistically significant difference between the two treatment groups (P > 0.05). Health-related quality of life in patients with allergic rhinitis improved significantly after 10 days of treatment with loratadine and bilastine, and the effectiveness of both was equivalent. © 2016 John Wiley & Sons Ltd.

Epidemiological and immunological studies suggest that maternal diet during pregnancy might affect the development of allergic diseases in the offspring. The authors set out to study the effect of maternal food consumption during pregnancy on the emergence of the International Study of Asthma and Allergies in Childhood (ISAAC)-based allergic outcomes: asthma, allergic rhinitis, and wheeze by the 5 yr of age. Data from 2441 children at 5 yr of age were analyzed within the Finnish Type 1 Diabetes Prediction and Prevention (DIPP) Nutrition Study, a population-based birth cohort study. Maternal diet was assessed with a validated food frequency questionnaire. In multiple regression models adjusted for known confounders, low maternal consumption of leafy vegetables (adjusted odds ratio [aOR]: 1.55; 95% CI: 1.21, 1.98), malaceous fruits (aOR: 1.45; 95% CI: 1.15, 1.84), and chocolate (aOR: 1.36; 95% CI: 1.09, 1.70) were positively associated with the risk of wheeze in children. High maternal consumption of fruit and berry juices was positively associated with the risk of allergic rhinitis (aOR: 1.40; 95% CI: 1.03, 1.90) in children. No associations were observed between maternal food consumption and asthma.

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).

Along with its high prevalence, the burden of allergic rhinitis rests upon the serious impact on quality of life of patients. Allergic rhinitis is associated with impairments in daily activities, work and school performance, and practical problems. Patients suffer from sleep disorders and emotional problems. Тhe advantages of sublingual immunotherapy on quality of life have only recently begun to emerge. The objective of this prospective real-life study was to evaluate the effect of a three-year course of sublingual immunotherapy with house dust mite (HDM) and grass pollen extracts on quality of life in adults with allergic rhinitis. A total number of 191 adult patients [105 (54,979%) men; mean age 27.3 years (SD-6.14)] with moderate to severe allergic rhinitis and clinically relevant sensitization to house dust mites or grass pollen were prospectively evaluated in the course of management of their disease. Health-related quality of life was assessed by Rhinoconjunctivitis Quality of Life Questionnaire at baseline and after three-year course of sublingual immunotherapy. The mean overall Qol score assessed at baseline and at the end of the third year of treatment decreased significantly in patients treated with HDM extract (from 2.95 to 0.76) as well as with Grass pollen extract (from 2.83 to 1.22) (р < 0.001). The improvements in treated with HDM extract were as followed: activities - 3.52 to 0.68; sleep- 2.48 to 0.31; general problems - 1.79 to 0.49; practical problems - 3.57 to 0.68; nasal symptoms - 3.91 to 0.74; eye symptoms - 2.92 to 0.39; emotions - 3.03 to 0.39.

Despite the availability of evidence-based guidelines for managing allergic rhinitis in primary care, management of the condition in the United Kingdom (UK) remains sub-optimal. Its high prevalence and negative effects on quality of life, school performance, productivity and co-morbid respiratory conditions (in particular, asthma), and high health and societal costs, make this a priority for developing novel models of care. Recent Australian research demonstrated the potential of a community pharmacy-based 'goal-focused' intervention to help people with intermittent allergic rhinitis to self-manage their condition better, reduce symptom severity and improve quality of life. In this pilot study we will assess the transferability of the goal-focused intervention to a UK context, the suitability of the intervention materials, procedures and outcome measures and collect data to inform a future definitive UK randomized controlled trial (RCT). A pilot cluster RCT with associated preliminary economic analysis and embedded qualitative evaluation. The pilot trial will take place in two Scottish Health Board areas: Grampian and Greater Glasgow & Clyde. Twelve community pharmacies will be randomly assigned to intervention or usual care group. Each will recruit 12 customers seeking advice or treatment for intermittent allergic rhinitis. Pharmacy staff in intervention pharmacies will support recruited customers in developing strategies for setting and achieving goals that aim to avoid/minimize triggers for, and eliminate/minimize symptoms of allergic rhinitis. Customers recruited in non-intervention pharmacies will receive usual care. The co-primary outcome measures, selected to inform a sample size calculation for a future RCT, are: community pharmacy and customer recruitment and completion rates; and effect size of change in the validated mini-Rhinoconjunctivitis Quality of Life Questionnaire between baseline, one-week and six-weeks post-intervention.

Allergic reactions to latex, including anaphylaxis may be a problem in certain individuals exposed to latex. Four atopic patients with symptoms of rhinitis, asthma, anaphylaxis, and/or urticaria upon contact with latex products were studied. The patients showed IgE binding to latex RAST disks ranging from 1.0 to 27.3 times the negative control. Latex products (gloves, balloons, and condoms) directly bound IgE from all four patients. Eluted proteins from the latex products inhibited IgE binding to commercial latex RAST disks. SDS-PAGE demonstrated multiple latex protein bands by Coomassie Blue staining between 14 and 66 kD. Immunoblotting showed specific IgE binding to latex proteins at 30 and 66 kD. These results indicate that latex-allergic patients have IgE directed against specific latex proteins. Allergy to latex can pose a substantial health risk to susceptible individuals.

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.

The prevalence of allergic rhinitis (AR) in Thailand continues to rise. We report the prevalence and evaluate its impact upon quality of life (QoL) in students on a metropolitan campus. From March 2013 to February 2014, 222 students from Thammasat University Medical School were evaluated using the International Study of Asthma and Allergies in Childhood Questionnaire (ISAAC) questionnaire and the rhinoconjunctivitis QoL questionnaire (Rcq-36) to assess subjective symptoms. Those students with clinical symptoms of AR underwent skin prick testing (SPT) using 5 common allergens found in Thailand. The association between AR and QoL was then determined using a paired t test. A total of 222 students were enrolled in the study; 86 (38.7%) were men. There were 183 (81.9%) students with AR symptoms and 130 (71.4%) students with positive results for SPT. The students' QoL as defined by the Rcq-36 revealed a significant worsening in students who self-reported rhinitis symptoms within the past 12 months. Compared to the non-AR group, in those with AR, eye symptoms were significantly more common. The prevalence of AR at a college campus was 58.5%. The presence of rhinitis symptoms was the highest predictor of the presence of AR, with 67.7% having subsequent positive SPT. Students with AR had poorer scores in every dimension of QoL as defined by the Rcq-36 when compared to their non-AR counterparts. Educational performances among the 2 groups were unaffected. © 2015 ARS-AAOA, LLC.

To systematically evaluate the efficacy of intranasal antihistamine in the treatment of allergic rhinitis. The randomized controlled trials (RCT) about intranasal antihistamines for the treatment of allergic rhinitis between January 1985 and January 2014 were searched in OVID, PubMed, EMBASE, CNKI, WanFang Data and Cochrane Library. Two reviewers independently screened the literatures, extracted the data, and evaluated the methodological quality, then meta-analysis was performed by using RevMan 5.1 software. A total of thirteen RCTs were included. The results of meta-analysis showed that the efficacy of intranasal antihistamine group was superior to the placebo group in total nasal symptom scores (TNSS), the difference was significant[WMD = -1.96, 95%CI (-2.06;-1.85), P < 0.01], and individual nasal symptom scores (blocked nose, rhinorrhea, and sneezing) [WMD = -0.18, 95%CI (-0.28;-0.08); WMD = -0.45, 95%CI (-0.52;-0.38); WMD = -0.41, 95%CI (-0.58;-0.24), all P < 0.01], with significant differences. There was no significant difference between the intranasal antihistamine group and the corticosteroid group in TNSS [WMD = -1.51, 95%CI (-3.51;0.49), P = 0.14], but the intranasal antihistamines group was superior to the corticosteroid group in individual nasal symptom scores (blocked nose, rhinorrhea, and sneezing) [WMD = -0.23, 95%CI (-0.40;-0.06); WMD = -0.35, 95%CI (-0.65;-0.05); WMD = -0.25, 95%CI (-0.42;-0.08), all P < 0.05], with significant differences. The intranasal antihistamine group was superior to the oral antihistamines group in TNSS [WMD = -0.88, 95%CI (-1.51;-0.25), P < 0.01]. Intranasal antihistamine is effective in the control of nasal symptoms in AR patients.

In anticipation of the development of guidelines for antigen-specific subcutaneous immunotherapy (SCIT), we present recommendations that can serve as guiding principles based on a review of the scientific literature. Clinical questions (CQs) concerning SCIT were prepared. Literature searches for publications between January 1990 and February 2011 were performed in PubMed, the Cochrane Library, and Japana Centra Revuo Medicina Web version 4. Qualified studies were analyzed and the results were evaluated, consolidated, and codified. We present answers for 13 CQs on the indications, methods, effectiveness and mechanisms of SCIT, with evidence-based recommendations. The guiding principles are intended to be applied to children (≤15 years old) and adults (≥16 years old) with allergic rhinitis (AR). These principles can be used by otorhinolaryngologists for diagnosis of AR, evaluation of severity and rhinoscopic findings, performance of antigen challenge tests, and management of systemic anaphylactic reactions associated with SCIT.

Respiratory allergies are the most common occupational diseases in the world. The aim of this study was to determine the prevalence of rhinitis and asthma among apprentices exposed to cotton dust in the clothing industry and to describe their epidemiologic and clinical profiles. We carried out a descriptive study of 600 apprentices in a textile and clothing vocational training centre in the Monastir area. The investigation comprised a questionnaire exploring risk factors and symptoms appearing during their training. Subjects who developed allergic respiratory symptoms at the work-place underwent a clinical examination, rhinomanometry and investigation of their allergic status and respiratory function. One hundred twenty apprentices (20%) developed allergic respiratory reactions due to exposure to textile dust (exclusively cotton) during their training, with a positive withdrawal-re-exposure test. Conjunctivitis (14.3%) and rhinitis (8.5%) were the most frequent allergic symptoms. Twenty eight apprentices (4.6%) presented symptoms of asthma. Rhinitis was associated with asthma in 45% of cases. Two cases of asthma were diagnosed clinically at the work-place following their exposure to textile dust. The prick test performed in 120 symptomatic apprentices was positive in 41.6% of cases. There was sensitization to pollens in 29 cases and to dermatophagoides in 13 cases. Cotton and wool allergy was noted in two cases. Allergic symptoms developing during the training were significantly more frequent in the atopic group, and they varied according to the intensity of textile dust exposure. In the textile and clothing industry the frequency of respiratory disorders caused by allergens remains high, especially in atopic apprentices who constitute a population at high risk.

A combination of antihistamines and oral corticosteroids is often used to treat acute symptoms of allergic rhinitis. To evaluate safety and efficacy of desloratadine plus prednisolone in the treatment of acute symptoms of children (2-12 years) with allergic rhinitis, and to compare it to dexchlorpheniramine plus betamethasone. Children with moderate/severe persistent allergic rhinitis and symptomatic (nasal symptoms score [0-12]≥6) were allocated in a double-blind, randomized fashion to receive dexchlorpheniramine plus betamethasone (n=105; three daily doses) or desloratadine plus prednisolone (n=105; single dose followed by two of placebo) for 7 days. At the beginning and end of the evaluation, the following were obtained: nasal symptoms score, extra nasal symptoms score, peak nasal inspiratory flow, blood biochemistry, and electrocardiogram. Ninety-six children of the dexchlorpheniramine plus betamethasone group and 98 of the desloratadine plus prednisolone group completed the protocol. The two groups were similar regarding initial and final nasal symptoms scores, extra nasal symptoms scores and peak nasal inspiratory flow. A drop of 76.4% and 79.1% for nasal symptoms score, 86.0% and 79.2% for extra nasal symptoms score, as well as an increase of 25.2% and 24.3% for peak nasal inspiratory flow occurred for those treated with desloratadine plus prednisolone and dexchlorpheniramine plus betamethasone, respectively. There were no significant changes in blood chemistry. Sinus tachycardia was the most frequent electrocardiogram change, but with no clinical significance. Drowsiness was reported significantly more often among those of dexchlorpheniramine plus betamethasone group (17.14%×8.57%, respectively). The desloratadine plus prednisolone combination was able to effectively control acute symptoms of rhinitis in children, improving symptoms and nasal function. Compared to the dexchlorpheniramine plus betamethasone combination, it showed similar clinical action

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

PubMed Central

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

The prevalence of asthma and allergic rhinitis in Colombia is increasing at the same rate as it is in other parts of the world. It has been determined that allergen-specific subcutaneous immunotherapy is effective in subjects with allergic rhinitis and asthma that are sensitized to house dust mites: Dermatophagoides farinae and Dermatophagoides pteronyssinus . To provide evidence on changes in the quality of life of subjects induced by allergen-specific subcutaneous immunotherapy with Dermatophagoides farinae and Dermatophagoides pteronyssinus . We selected 76 subjects with a diagnosis of respiratory allergy with sensitization to Dermatophagoides farinae and Dermatophagoides pteronyssinus . The instruments used for evaluating the quality of life were Kidscreen-27 and SF-36. These instruments were applied twice for each subject: once during the first visit, and during the twelfth visit corresponding to the one-year follow-up. Twenty-two subjects completed this study. After one year of treatment with allergen-specific subcutaneous immunotherapy, we found positive changes in terms of the quality of life. In children, the main change was in the School Environment domain while in adults it was in the Physical Function domain. We evaluated, for the first time in Colombia, benefits induced by allergen-specific subcutaneous immunotherapy for dust mites in terms of quality of life in subjects with allergic rhinitis and asthma. These results demonstrated that allergen-specific subcutaneous immunotherapy produces a positive influence on subjects sensitized to dust mites that received allergen-specific subcutaneous immunotherapy to Dermatophagoides farinae and Dermatophagoides pteronyssinus after one year.

The aim of the study was to compare the efficacy of instruments to assess quality of life (QoL) in patients with moderate to severe persistent allergic rhinitis (PAR) vs intermittent allergic rhinitis (IAR). There were 106 patients with PAR and 99 with IAR and 50 healthy subjects in the control group. Questionnaire results were obtained using the Medical Outcomes Survey Short Form 36 (SF-36), a visual analog scale (VAS), and the rhinoconjunctivitis quality of life questionnaire (RQLQ) and were analyzed using correlational analysis. Correlations between the total scores and most domains of the 3 questionnaires were stronger in patients with PAR than in those with IAR, although the difference between groups was significant only for the RQLQ (P < .01). The QoL was worse in the PAR subgroup than in the IAR subgroup in the domains of social functioning in the SF-36 and for items of sleeping problems and activity limitations in the RQLQ. There were significant correlations between RQLQ and VAS-eye symptoms in the PAR subgroup but not in the IAR subgroup. The 3 questionnaires differentiated patients with AR from the healthy population, with significant but weak correlation with each other. The correlations were higher in patients with PAR than in those with IAR. The moderate to severe PAR has a greater effect on quality of life than IAR. Eye symptoms affected the QoL more in patients with PAR than in those with IAR. Copyright © 2011 Elsevier Inc. All rights reserved.

Asthma, rhinitis and eczema often co-occur in children, but their interrelationships at the population level have been poorly addressed. We assessed co-occurrence of childhood asthma, rhinitis and eczema using unsupervised statistical techniques. We included 17 209 children at 4 years and 14 585 at 8 years from seven European population-based birth cohorts (MeDALL project). At each age period, children were grouped, using partitioning cluster analysis, according to the distribution of 23 variables covering symptoms 'ever' and 'in the last 12 months', doctor diagnosis, age of onset and treatments of asthma, rhinitis and eczema; immunoglobulin E sensitization; weight; and height. We tested the sensitivity of our estimates to subject and variable selections, and to different statistical approaches, including latent class analysis and self-organizing maps. Two groups were identified as the optimal way to cluster the data at both age periods and in all sensitivity analyses. The first (reference) group at 4 and 8 years (including 70% and 79% of children, respectively) was characterized by a low prevalence of symptoms and sensitization, whereas the second (symptomatic) group exhibited more frequent symptoms and sensitization. Ninety-nine percentage of children with comorbidities (co-occurrence of asthma, rhinitis and/or eczema) were included in the symptomatic group at both ages. The children's characteristics in both groups were consistent in all sensitivity analyses. At 4 and 8 years, at the population level, asthma, rhinitis and eczema can be classified together as an allergic comorbidity cluster. Future research including time-repeated assessments and biological data will help understanding the interrelationships between these diseases. © 2015 John Wiley & Sons A/S.

Specific immunotherapy is the only potentially curative treatment in patients with allergic rhinitis and allergic asthma. Health economic evaluations on this treatment, particularly in a German context, are sparse. To evaluate the cost-effectiveness of specific subcutaneous immunotherapy (SCIT) in addition to symptomatic treatment (ST) compared with ST alone in a German health care setting. The analysis was performed as a health economic model calculation based on Markov models. In addition, we performed a concomitant expert board composed of allergy experts in pediatrics, dermatology, pneumology, and otolaryngology. The primary perspective of the study was societal. Additional sensitivity analyses were performed to prove our results for robustness. The SCIT and ST combination was associated with annual cost savings of Euro140 per patient. After 10 years of disease duration, SCIT and ST reach the breakeven point. The overall incremental cost-effectiveness ratio (ICER) was Euro-19,787 per quality-adjusted life-year (QALY), with a range that depended on patient age (adults, Euro-22,196; adolescents, Euro-14,747; children, Euro-12,750). From a third-party payer's perspective, SCIT was associated with slightly additional costs. Thus, the resulting ICER was Euro8,308 per QALY for all patients. Additional SCIT was associated with improved medical outcomes and cost savings compared with symptomatic treatment alone according to a societal perspective. Taking a European accepted ICER threshold of up to Euro50,000 per QALY into account, additional SCIT is considered clearly cost-effective compared with routine care in Germany. The degree of cost-effectiveness is strongly affected by costs related to SCIT and the target population receiving such treatment.

Identification and management of undiagnosed and undertreated allergic rhinitis in adults and children.

PubMed

Stewart, M G

2008-05-01

Allergic rhinitis (AR) is a common health problem that affects adults, adolescents and children and is often undiagnosed or inadequately treated. Because AR is not a life-threatening disease, many patients do not seek medical treatment for their symptoms, and others self-medicate with over-the-counter medications, often sedating antihistamines. However, untreated or inadequately treated AR can substantially impair overall quality of life (QOL) by causing fatigue, headache, cognitive impairment and other problems. The risk for comorbid conditions, such as asthma, otitis media, and lymphoid hypertrophy with obstructive sleep apnea, can increase, and the symptoms of AR can worsen if AR is not adequately treated. Among the symptoms of AR, nasal congestion has been described by patients as the most bothersome because it disrupts sleep, resulting in diminished daytime performance. A new congestion screening tool, the Congestion Quantifier, has been developed to aid in the diagnosis and treatment of AR and to help guide treatment decisions. Intranasal corticosteroids (INSs) are recommended as effective pharmaceutical treatments for controlling the symptoms of AR. Randomized, controlled trials in children and adults have demonstrated that INSs relieve rhinitis symptoms, thereby improving QOL in individuals with seasonal or perennial AR. Most INSs are approved for use in children >or=6 years of age, but mometasone furoate and fluticasone furoate are approved for use in children as young as 2 years of age and fluticasone propionate for children >or=4 years old. Long-term benefits have also been seen with the use of immunotherapy, although some patients, especially children, resist the injections used in subcutaneous immunotherapy. Recent studies with sublingual immunotherapy have indicated that it might be an effective and well-tolerated alternative to immunotherapy injections.

Intermittent allergic rhinitis (IAR) causes patients distress and impairs their work performance and quality of life. A variety of medicines are used by sufferers whose anguish frequently leads to trying new treatments, increasingly from herbal sources. Prospective, randomized, double-blind, parallel group comparison study of Butterbur extract (Ze 339; 8 mg total petasine; one tablet thrice-daily), fexofenadine (Telfast 180, one tablet once-daily) and placebo in 330 patients. Protocol and analysis were according to the latest guidelines on new treatments for allergic rhinitis. The primary efficacy variable was a change in symptoms from baseline to endpoint during daytime. The secondary efficacy variables were: (a) as per primary variable (evening/night); (b) Physician's global assessment; (c) Responder rates. Safety was closely monitored. Both active treatments were individually significantly superior to placebo (p<0.001) in improving symptoms of IAR, while there were no differences between the two active treatments (p=0.37). Superiority to placebo was similarly shown during the evening/night (p<0.001), by physicians' own assessment and by responder rates. Both treatments were well tolerated. Butterbur Ze 339 and Fexofenadine are comparably efficacious relative to placebo. Despite being a herbal drug, Butterbur Ze 339 has now been subject to a series of well controlled trials and should be considered as an alternative treatment for IAR.

The aim of this study was to evaluate the efficacy of OM-85 in reducing the incidence of respiratory tract infections (RTIs) in patients with allergic rhinitis, asthma, or chronic obstructive pulmonary disease (COPD), and its effect on immunological parameters, namely serum and secretory IgA levels. This was an open-label, prospective, sequential study which included 84 consecutive patients aged 16-65 years, who presented with recurrent (three or more) respiratory infections during the year prior to study entry. In the first year of the study, patients received standard optimized care (SOC), according to their underlying disease condition (asthma, allergic rhinitis, or COPD). In the following year, patients received treatment with OM-85 oral bacterial lysate (one 7 mg capsule daily for ten consecutive days per month, for 3 months), with a 6-month follow-up. Medical history, clinical symptoms, serum, and secretory IgA levels, and the number of infections and exacerbations were evaluated before and after treatment. There was a decrease in the total number of RTIs before the OM-85 treatment period (SOC only) compared to the year before the study start [69/266 (corresponding to a 74 % reduction)] and an additional decrease [38/69 (corresponding to a 45 % reduction)] after OM-85 treatment; p < 0.05. There was also a significant reduction in the total number of exacerbations related to the patients' underlying medical conditions, which decreased from 55 to 35 during OM-85 (+SOC) treatment, corresponding to a reduction of 36 %. In addition, an increase in serum and secretory IgA levels which coincided with the administration of OM-85 was observed. Our results showed the clinical benefits of OM-85 in reducing RTIs and exacerbations of the underlying medical condition, in patients with allergic rhinitis, asthma, or COPD.

The ragweed- and histamine-induced decreases in nasal patency in cohorts of ragweed-sensitized and nonsensitized dogs were assessed. The volume of nasal airways (V(NA)) was assessed by acoustic rhinometry and resistance to airflow (R(NA)) by anterior rhinomanometry. Histamine delivered to the nasal passages of five dogs caused a rapid and prolonged increase in R(NA) (0.75 +/- 0.26 to 3.56 +/- 0.50 cmH(2)O. l(-1). min), an effect that was reversed by intranasal delivery of aerosolized phenylephrine. Ragweed challenge in five ragweed-sensitized dogs increased R(NA) from 0.16 +/- 0.02 to 0.53 +/- 0.07 cmH(2)O. l(-1). min and decreased V(NA) from 12.5 +/- 1.9 to 3.9 +/- 0.3 cm(3), whereas administration of saline aerosol neither increased R(NA) nor decreased V(NA). Prior administration of d-pseudoephedrine (30 mg po) attenuated the ragweed-induced increase in R(NA) and decrease in V(NA). Ragweed challenge changed neither R(NA) nor V(NA) in four nonsensitized dogs. Mediator-induced nasal congestion and allergen-induced allergic rhinitis in ragweed-sensitized dogs, which exhibit symptoms similar to human disease, can be used in the evaluation of safety and efficacy of antiallergic activity of potential drugs.

Enterotoxins produced by Staphylococcus aureus and their specific IgE antibodies were thought to be important in worsening atopic dermatitis. However, few studies have documented an association between S. aureus or its exotoxins and exacerbations of upper airway/nasal disease. In the current study, we determined the prevalence of serum-specific IgE towards staphylococcal enterotoxin A, B, C, D (SEA, SEB, SEC, SED) and toxic shock syndrome toxin 1 (TSST-1) in patients suffering from rhinitis and/or asthma due to allergy. Therefore, we examined whether SEA, SEB, SEC, SED and TSST-1 were important in worsening the clinical status of patients allergic to house dust mites by means of assessing serum eosinophil cationic protein (ECP), which is thought to be a reliable marker of asthma and rhinitis severity. 198 patients with persistent allergic rhinitis and/or asthma due to house dust mites were evaluated. Specific IgE towards SEA, SEB, SEC, SED, TSST-1, timothy grass and birch pollen recombinant allergens, and other aeroallergen extracts from common allergen sources were evaluated by the Pharmacia CAP System. Serum ECP was assessed, too. The percentages of sensitization to staphylococcal enterotoxins of 198 house dust mite-allergic patients were as follows: TSST-1-specific IgE 24.7% (n=49), SEC-specific IgE 22.2% (n=44), SEB-specific IgE 15.1% (n=30), SEA-specific IgE 9.1% (n=18), and SED-specific IgE 5.5% (n=11). Out of 198 individuals allergic to house dust mites 136 patients suffering from persistent rhinitis were subdivided into two subgroups: 53 patients with serum-specific IgE to at least one staphylococcal enterotoxin and 83 patients without specific IgE towards staphylococcal enterotoxins. Patients sensitive to staphylococcal enterotoxins had higher serum ECP levels than patients lacking specific IgE to SEA, SEB, SEC, SED and TSST-1(geometric mean 24.3 vs. 16.6 microg/100 ml; p=0.029), as well as total IgE levels (geometric mean 564 vs. 161 kU/l, p=0.00063) and

In teenagers with perennial allergic rhinitis, exposure to tobacco cigarette smoke increases the count of eosinophils in the nasal mucosa; the recruitment of eosinophils arises from the combined action of a number of cellular and molecular signals, including eotaxin. To assess the effect of exposure to tobacco cigarette smoke on the count of immunoreactive cells to eotaxin-1 and eosinophils on the nasal mucosa of children and teenagers with perennial allergic rhinitis. In a cross-sectional study, forty-four patients were evaluated (aged 7-19 years old): 22 with and 22 with no exposure to tobacco cigarette smoke. After replying to 2 validated questionnaires, on Asthma and Allergies in Childhood and on the severity of nasal symptoms, nasal mucosal samples were obtained by scraping the middle one-third of the inferior turbinates. Then counts of immunoreactive cells to eotaxin-1 and eosinophils were assessed by immunohistochemistry. Patients with exposure to tobacco cigarette smoke showed higher cell counts of both eotaxin-1 and eosinophils than patients with no exposure to the smoke, with no correlation between the two variables. However, both counts, of eotaxin-1 and eosinophils, were related to the cotinine/creatinine ratio. Exposure to tobacco cigarette smoke can increase eotaxin-1 and the count of eosinophils in the nasal mucosa of young patients with perennial allergic rhinitis.

Brain-derived neurotrophic factor (BDNF) is a secretory protein that has been implicated in the pathogenesis of allergic rhinitis (AR), atopic asthma, and eczema, but it is currently unknown whether BDNF polymorphisms influence susceptibility to moderate-to-severe AR. We sought to identify disease associations and the functional effect of BDNF genetic variants in patients with moderate-to-severe AR. Tagging single nucleotide polymorphisms (SNPs) spanning the BDNF gene were selected from the human HapMap Han Chinese from Beijing (CHB) data set, and associations with moderate-to-severe AR were assessed in 2 independent cohorts of Chinese patients (2216 from Shandong province and 1239 living in Singapore). The functional effects of the BDNF genetic variants were determined by using both in vitro and ex vivo assays. The tagging SNP rs10767664 was significantly associated with the risk of moderate-to-severe AR in both Singapore Chinese (P = .0017; odds ratio, 1.324) and Shandong Chinese populations (P = .039; odds ratio, 1.180). The coding nonsynonymous SNP rs6265 was in perfect linkage with rs10767664 and conferred increased BDNF protein secretion by a human cell line in vitro. Subjects bearing the AA genotype of rs10767664 exhibited increased risk of moderate-to-severe AR and displayed increased BDNF protein and total IgE levels in plasma. Using a large-scale expression quantitative trait locus study, we demonstrated that BDNF SNPs are significantly associated with altered BDNF concentrations in peripheral blood. A common genetic variant of the BDNF gene is associated with increased risk of moderate-to-severe AR, and the AA genotype is associated with increased BDNF mRNA levels in peripheral blood. Together, these data indicate that functional BDNF gene variants increase the risk of moderate-to-severe AR. Copyright © 2015 American Academy of Allergy, Asthma & Immunology.

Induction of oral tolerance (OT) is known to prevent allergic inflammation in models of asthma. This study investigated the preventive effect of OT and airway remodeling in a mouse model of allergic rhinitis (AR). An in vivo study using an animal model. Catholic Research Institutes of Medical Science. Forty six-week-old, female BALB/c mice were divided into four groups: control, AR, low-dose OT, and high-dose OT. To induce OT, mice were fed ovalbumin (OVA) before sensitization with OVA/aluminum hydroxide, 1 mg for six days in the low-dose OT group and a 25 mg single dose in the high-dose OT group. Mice in the AR group were fed phosphate-buffered saline. After sensitization followed by challenges with OVA during six weeks, nasal behaviors, interleukin (IL)-13 and interferon gamma (IFN-gamma) levels in nasal lavage (NAL) fluids, as well as OVA-specific IgE levels in serum, were measured. The degree of goblet cell hyperplasia and thickness of lamina propria were observed in nasal tissues by periodic acid-Schiff and Masson's trichrome stain. A P value < 0.05 was accepted as statistically significant. Both OT groups showed a significant decrease in inflammatory cells, IL-13 and IFN-gamma in NAL fluids, as well as OVA-specific IgE levels in serum compared with the AR group. In addition, the degree of goblet cell hyperplasia and thickness of lamina propria were attenuated in both OT groups compared with the AR group. Further, these alterations did not differ significantly between the two OT groups. These results suggest that OT may effectively reduce allergic inflammation as well as airway remodeling in a mouse model of AR.

Several studies highlighted a great variability, both between and within countries, in the prevalence of asthma and chronic airways diseases. To evaluate if geo-climatic variations can explain the heterogeneity in the prevalence of asthma and respiratory diseases in Italy. Between 2006 and 2010, a postal screening questionnaire on respiratory health was administered to 18,357 randomly selected subjects, aged 20-44, living in 7 centers in northern, central, and southern Italy. A random-effects meta-analysis was fitted to evaluate the between-centers heterogeneity in the prevalence of asthma, asthma-like symptoms, allergic rhinitis, and chronic bronchitis (CB). A principal component analysis (PCA) was performed to synthetize the geo-climatic information (annual mean temperature, range of temperature, annual rainfalls, global solar radiations, altitude, distance from the sea) of all the 110 Italian province capital towns. The associations between these geo-climatic components obtained with PCA and the prevalence of respiratory diseases were analyzed through meta-regression models. 10,464 (57%) subjects responded to the questionnaire. There was a significant between-centers heterogeneity in the prevalence of asthma (I(2)=59.5%, p=0.022) and CB (I(2)=60.5%, p=0.019), but not in that of asthma-like symptoms or allergic rhinitis. Two independent geo-climatic components explaining together about 80% of the overall geo-climatic variability were identified: the first principally summarized the climatic variables; the second the topographic ones. Variations in the prevalence of asthma across centers were significantly associated with differences in the climatic component (p=0.017), but not with differences in the topographic one. Our findings suggest that climate play a role in determining the between-center heterogeneity in the prevalence of asthma in Italy, with higher prevalence in dry-hot Mediterranean climates, and lower in rainy-cold northern climates.

Epidemiology of allergic conjunctivitis: clinical appearance and treatment patterns in a population-based study.

Leonardi, Andrea; Castegnaro, Angela; Valerio, Alvise La Gloria; Lazzarini, Daniela

2015-10-01

To analyse the most recently published studies on the prevalence of allergic conjunctivitis alone or in association with allergic rhinitis, and the clinical and demographic aspects of the disease. Allergic conjunctivitis or conjunctival symptoms are present in 30-71% of patients with allergic rhinitis. Allergic conjunctivitis alone has been estimated in 6-30% of the general population and in up to 30% in children alone or in association with allergic rhinitis. Seasonal allergic conjunctivitis is the most frequent form; however, studies from tertiary, ophthalmology referral centers report that the chronic forms, such as vernal and atopic keratoconjunctivitis, are the most frequently seen by ophthalmologists. A recent large survey performed at a national level involving 304 ophthalmologists showed that the majority of patients with allergic conjunctivitis suffer annually of few episodes of mild ,intermittent conjunctivitis. However, 30% of patients are affected by frequent episodes with intense and persistent symptoms. Treatment is frequently not appropriate. Even though allergic conjunctivitis is often associated to allergic rhinitis, epidemiology studies frequently do not include specific ophthalmological evaluations. An understanding of allergic conjunctivitis disease, its prevalence, demographics and treatment paradigms will provide important information towards understanding its pharmacoeconomics and burden on the national health systems.

Targeting congestion in allergic rhinitis: the importance of intranasal corticosteroids.

PubMed

Marple, Bradley F

2008-01-01

The cardinal nasal symptoms of allergic rhinitis (AR) are sustained by an underlying inflammatory process. Congestion is one of the most prominent and distressing symptoms for patients and is strongly associated with a broadly deteriorated quality of life and significant losses in productivity. The purpose of this study was to explore the role of intranasal corticosteroids (INSs) in down-regulating the inflammatory response to allergen and their clinical efficacy on AR symptoms, particularly congestion. AR is characterized by an influx of inflammatory cells and mediators into the nasal mucosa after antigen exposure. The response is biphasic, encompassing an early and a late phase. Antigen exposure has a priming effect, decreasing the threshold for subsequent allergic reaction on rechallenge and increasing the responsiveness of the nasal mucosa. INSs are a mainstay of therapy for AR and the most effective intervention for nasal congestion and other nasal symptoms, with established superiority to antihistamines, decongestants, and leukotriene antagonists. In addition to symptom relief, INSs suppress numerous stages of the inflammatory cascade, inhibiting the influx of inflammatory cells and mediators. Topical nasal corticosteroids have a low incidence of local adverse effects, negligible systemic absorption, and excellent safety. Congestion is one of the most bothersome symptoms of AR. INS therapy improves AR symptoms, with particular efficacy in relieving congestion, by attenuating nasal hyperresponsiveness. Pretreatment with INSs has been shown to relieve early and late-phase clinical symptoms of AR. Modification of the disease process results in significant relief of symptoms and leads to fewer disease exacerbations.

Allergic rhinitis (AR) is one of the most common chronic allergic respiratory diseases worldwide. Various practical guidelines for AR have been developed and updated to improve the care of AR patients; however, up to 40% patients remain symptomatic. The unmet need for AR care is one of the greatest public health problems in the world. The gaps between guideline and real-world practice, and differences according to the region, culture, and medical environments may be the causes of unmet needs for AR care. Because there is no evidence-based AR practical guideline reflecting the Korean particularity, various needs are increasing. The purpose of the study was to evaluate whether existing guidelines are sufficient for AR patient management in real practice and whether development of regional guidelines to reflect regional differences is needed in Korea. A total of 99 primary physicians comprising internists, pediatricians, and otolaryngologists (n=33 for each) were surveyed by a questionnaire relating to unmet needs for AR care between June 2 and June 16 of 2014. Among 39 question items, participants strongly agreed on 15 items that existing guidelines were highly insufficient and needed new guidelines. However, there was some disagreement according to specialties for another 24 items. In conclusion, the survey results demonstrated that many physicians did not agree with the current AR guideline, and a new guideline reflecting Korean particularity was needed.

Clinical evidence suggests that acupuncture improves symptoms in persistent allergic rhinitis, but the physiologic basis of these improvements is not well understood. A randomized, sham-controlled trial of acupuncture for persistent allergic rhinitis in adults investigated possible modulation of mucosal immune responses. A total of 151 individuals were randomized into real and sham acupuncture groups (who received twice-weekly treatments for 8 weeks) and a no acupuncture group. Various cytokines, neurotrophins, proinflammatory neuropeptides, and immunoglobulins were measured in saliva or plasma from baseline to 4-week follow-up. Statistically significant reduction in allergen specific IgE for house dust mite was seen only in the real acupuncture group, from 18.87 kU/L (95% CI, 10.16-27.58 kU/L) to 17.82 kU/L (95% CI, 9.81-25.83 kU/L) (P = .04). A mean (SE) statistically significant down-regulation was also seen in proinflammatory neuropeptide substance P (SP) 18 to 24 hours after the first treatment from 408.74 (299.12) pg/mL to 90.77 (22.54) pg/mL (P = .04). No significant changes were seen in the other neuropeptides, neurotrophins, or cytokines tested. Nasal obstruction, nasal itch, sneezing, runny nose, eye itch, and unrefreshed sleep improved significantly in the real acupuncture group (postnasal drip and sinus pain did not) and continued to improve up to 4-week follow-up. Acupuncture modulated mucosal immune response in the upper airway in adults with persistent allergic rhinitis. This modulation appears to be associated with down-regulation of allergen specific IgE for house dust mite, which this study is the first to report. Improvements in nasal itch, eye itch, and sneezing after acupuncture are suggestive of down-regulation of transient receptor potential vanilloid 1.

To evaluate how well the medications currently approved in the United States for allergic rhinitis (AR) treat nasal symptoms when examined according to Food and Drug Administration-indicated uses and dosages. MEDLINE (1966 onward), EMBASE (1974 onward), and the Cochrane Library (2007) were systematically searched according to the following criteria defined at a roundtable meeting of the authors: randomized controlled trial, at least a 2-week duration, and approved indication and dosage in the United States. Data from studies that met the inclusion criteria were extracted into evidence tables, which were reviewed twice by the full panel of authors. Individual panel members also were asked to comment on abstracts, articles, and summary tables based on their known expertise. The entire faculty approved the selection of studies included in this review. Fifty-four randomized, placebo-controlled studies involving more than 14,000 adults and 1,580 children with AR met the criteria for review: 38 studies of seasonal allergic rhinitis (SAR; n = 11,980 adults and 946 children) and 12 studies of perennial allergic rhinitis (PAR; n = 3,800 adults and 366 children). The median percentage changes from baseline for total nasal symptom score for SAR were as follows: nasal antihistamines, -22.2%; oral antihistamines, -23.5%; intranasal steroids (INSs), -40.7%; and placebo, -15.0%. For PAR, the changes were as follows: oral antihistamines, -51.4%; INSs, -37.3%; and placebo, -24.8%. Data for mediator antagonists were limited. The data, although limited, confirm that INSs produce the greatest improvements in nasal symptoms in patients with SAR. In addition, INSs are effective for PAR, but the data were of variable quality, and oral antihistamines may be equally effective for some patients. The reporting of published data should be standardized to permit better comparisons in future studies.

Background: Skin prick test (SPT) is the most effective diagnostic test to detect IgE mediated type I allergic reactions like allergic rhinitis, atopic asthma, acute urticaria, food allergy etc. SPTs are done to know allergic sensitivity and applied for devising immunotherapy as the therapeutic modality. Materials and Methods: This prospective study was conducted in the department of Immunology and Molecular medicine at SKIMS. A total of 400 patients suffering from allergic rhinitis, asthma and urticaria were recruited in this study. SPT was performed with panel of allergens including house dust mite, pollens, fungi, dusts, cockroach, sheep wool and dog epithelia. Allergen immunotherapy was given to allergic rhinitis and asthmatic patients as therapeutic modality. Results: In our study, age of patients ranged from 6 to 65 years. Majority of patients were in the age group of 20-30 years (72%) with Male to female ratio of 1:1.5. Of the 400 patients, 248 (62%) had urticaria, 108 (27%) patients had allergic rhinitis and 44 (11%) patients had asthma. SPT reaction was positive in 38 (86.4%) with allergic asthma, 74 (68.5%) patients with allergic rhinitis and 4 (1.6%) patient with urticaria, respectively. Allergen immunotherapy was effective in 58% patients with allergic rhinitis and 42% allergic asthma. Conclusion: Identifiable aeroallergen could be detected in 86.4% allergic asthma and 68.5% allergic rhinitis patients by SPT alone. Pollens were the most prevalent causative allergen. There was significant relief in the severity of symptoms, medication intake with the help of allergen immunotherapy. PMID:23372205

The fruits of Xanthium strumarium L. (Asteraceae) have been used extensively in China for treatment of various diseases such as allergic rhinitis (AR), tympanitis, urticaria and arthritis or ozena. This study was designed to systemically investigate the effects of the caffeoylxanthiazonoside (CXT) isolated from fruits of X. strumarium on AR in rodent animals. Animals were orally administered with CXT. Anti-allergic activity of CXT was evaluated by passive cutaneous anaphylaxis test (PCA); acetic acid-induced writhing tests were used to evaluate the analgesic effects of CXT; acetic acid-induced vascular permeability tests were performed to evaluate anti-inflammatory effect of CXT. Then, the model AR in rats was established to evaluate the effects of CXT on AR with the following tests: the sneezing and nasal scratching frequencies, IgE level in serum, and histopathological examinations. Our results demonstrated that CXT had favorable anti-allergic, anti-inflammatory and analgesic effects. Additionally, we found that CXT was helpful to ameliorate the nasal symptoms and to down-regulate IgE levels in AR rats. Thus, we suggested that CXT can be treated as a candidate for treating AR.

Aims: To investigate the effect of breast feeding on allergic disease in infants up to 2 years of age. Methods: A birth cohort of 4089 infants was followed prospectively in Stockholm, Sweden. Information about various exposures was obtained by parental questionnaires when the infants were 2 months old, and about allergic symptoms and feeding at 1 and 2 years of age. Duration of exclusive and partial breast feeding was assessed separately. Symptom related definitions of various allergic diseases were used. Odds ratios (OR) and 95% confidence intervals (CI) were estimated in a multiple logistic regression model. Adjustments were made for potential confounders. Results: Children exclusively breast fed during four months or more exhibited less asthma (7.7% v 12%, ORadj = 0.7, 95% CI 0.5 to 0.8), less atopic dermatitis (24% v 27%, ORadj = 0.8, 95% CI 0.7 to 1.0), and less suspected allergic rhinitis (6.5% v 9%, ORadj = 0.7, 95% CI 0.5 to 1.0) by 2 years of age. There was a significant risk reduction for asthma related to partial breast feeding during six months or more (ORadj = 0.7, 95% CI 0.5 to 0.9). Three or more of five possible allergic disorders—asthma, suspected allergic rhinitis, atopic dermatitis, food allergy related symptoms, and suspected allergic respiratory symptoms after exposure to pets or pollen—were found in 6.5% of the children. Exclusive breast feeding prevented children from having multiple allergic disease (ORadj = 0.7, 95% CI 0.5 to 0.9) during the first two years of life. Conclusion: Exclusive breast feeding seems to have a preventive effect on the early development of allergic disease—that is, asthma, atopic dermatitis, and suspected allergic rhinitis, up to 2 years of age. This protective effect was also evident for multiple allergic disease. PMID:12456543

To observe 18β-glycyrrhetinic acid (GA) impact on ultrastructure of tight junctions (TJs) of nasal mucosa epithelial cells in rats models of allergic rhinitis (AR). Ninety-six Wistar rats were randomly divided into control group, model group, loratadine group, and 18β-glycyrrhetinic acid group, and each group had 24 rats. Ovalbumin was used to establish a rat AR model. The behavioral changes and the tight junctions of nasal epithelial were observed and compared in different groups after 2,4,6 and 10 weeks intervention. The length of TJs in allergic rhinitis model became shorter, electron-high-density plasma membrane became thicker, number of the integration loci reduced and gap of TJs widened or even ruptured. With the consistent effect of allergens,the changes of TJs in the model group aggravated gradually,and the changes of ultrastructure of TJs in 18β-glycyrrhetinic acid group was relieved apparently compared to model group and even were close to the control model with time. 18β-glycyrrhetinic acid can recover the ultrastructure of the tight junctions of AR rat nasal epithelial cells.

Environmental factors have been found to be associated with allergic diseases, but it is unclear which environmental factor during which exposure window causes what kind of allergic diseases. We investigated association between exposure to some predominant outdoor and indoor environmental factors during preconceptional, prenatal, and postnatal periods and allergic diseases/symptoms in 2598 children in China. Children's lifetime incidence of allergic diseases and current prevalence of allergic symptoms and exposure to indoor new furniture/redecoration and mold/dampness was surveyed by a questionnaire. Exposure to outdoor air pollutants was estimated by the concentrations measured at air quality monitoring stations. Multiple logistic regression model was used to evaluate the associations between outdoor air pollutants and indoor environmental factors and allergic diseases (asthma, allergic rhinitis, and eczema) and symptoms (wheezing, night cough, and rhinitis-like). We found that preconceptional, prenatal, and postnatal exposure to outdoor industrial and traffic air pollutants were significantly associated with increase in the risk of childhood asthma, and also positively associated with allergic rhinitis and eczema. However, we cannot distinguish the effect of outdoor air pollutants and exposure windows because of their high correlations. New furniture was associated with eczema and allergic rhinitis during postnatal exposure, but redecoration associated with asthma and eczema during prenatal exposure. Indoor visible mold/damp stains was significant for eczema during prenatal exposure and asthma during postnatal exposure respectively, but window condensation was significant for all childhood allergic diseases during both prenatal and postnatal exposures. Allergic symptoms in children were found to be associated with exposure to indoor factors only.

The fact that breastfeeding may protect against allergic diseases remains controversial, with hardly any reports from developing countries. Prolonged breastfeeding was shown to reduce the risk of allergic and respiratory diseases. The aim of this study was to assess the relationship between breastfeeding and the development of childhood asthma and allergic diseases in Qatari children at age 0-5 years. Additionally, this study investigated the effect of prolonged breastfeeding on the allergic diseases in a developing country. This is a cross sectional survey. Well baby clinics and Pediatric clinics in the 11 Primary Health Care Centers and Hamad General Hospital, Hamad Medical Corporation, State of Qatar. A multistage sampling design was used and a representative sample of 1500 Qatari infants and pre-school children with age range of 0-5 years and mothers aged between 18 to 47 years were surveyed during the period from October 2006 to September 2007 in Qatar. Out of the 1500 mothers of children, 1278 mothers agreed to participate in this study with the response rate of 85.2%. A confidential, anonymous questionnaire was completed by the selected subjects assessing breastfeeding and allergic diseases. Questionnaires were administered to women who were attending Primary Health Centers for child immunization. Questionnaire included allergic rhinitis, wheezing, eczema, and additional questions included mode and duration of breastfeeding, tobacco smoke exposure, number of siblings, family income, level of maternal education, parental history of allergies. Univariate and multivariate statistical methods were performed for statistical analysis. More than half of the infants (59.3%) were exclusively breastfed, followed by infants with partial breastfeeding (28.3%) and artificial fed (12.4%). There was a significant difference found across these three categories of infants in terms of their age groups, smoking status of father, socio-economic status and parental consanguinity

Background Despite the availability of evidence-based guidelines for managing allergic rhinitis in primary care, management of the condition in the United Kingdom (UK) remains sub-optimal. Its high prevalence and negative effects on quality of life, school performance, productivity and co-morbid respiratory conditions (in particular, asthma), and high health and societal costs, make this a priority for developing novel models of care. Recent Australian research demonstrated the potential of a community pharmacy-based ‘goal-focused’ intervention to help people with intermittent allergic rhinitis to self-manage their condition better, reduce symptom severity and improve quality of life. In this pilot study we will assess the transferability of the goal-focused intervention to a UK context, the suitability of the intervention materials, procedures and outcome measures and collect data to inform a future definitive UK randomized controlled trial (RCT). Methods/Design A pilot cluster RCT with associated preliminary economic analysis and embedded qualitative evaluation. The pilot trial will take place in two Scottish Health Board areas: Grampian and Greater Glasgow & Clyde. Twelve community pharmacies will be randomly assigned to intervention or usual care group. Each will recruit 12 customers seeking advice or treatment for intermittent allergic rhinitis. Pharmacy staff in intervention pharmacies will support recruited customers in developing strategies for setting and achieving goals that aim to avoid/minimize triggers for, and eliminate/minimize symptoms of allergic rhinitis. Customers recruited in non-intervention pharmacies will receive usual care. The co-primary outcome measures, selected to inform a sample size calculation for a future RCT, are: community pharmacy and customer recruitment and completion rates; and effect size of change in the validated mini-Rhinoconjunctivitis Quality of Life Questionnaire between baseline, one-week and six-weeks post

Allergen-specific immunotherapy is the only causative treatment of IgE-mediated allergic disorders. The most common administration route is subcutaneous, which may necessitate more than 50 allergen injections during 3 to 5 years. Recent evidence suggests that direct intralymphatic injections could yield faster beneficial results with considerably lower allergen doses and markedly reduced numbers of injections. To evaluate the effects of intralymphatic allergen-specific immunotherapy in pollen-allergic patients. In an open pilot investigation followed by a double-blind, placebo-controlled study, patients with allergic rhinitis were treated with 3 intralymphatic inguinal injections of ALK Alutard (containing 1000 SQ-U birch pollen or grass pollen) or placebo (ALK diluent). Clinical pre- and posttreatment parameters were assessed, the inflammatory cell content in nasal lavage fluids estimated, and the activation pattern of peripheral T cells described. All patients tolerated the intralymphatic immunotherapy (ILIT) treatment well, and the injections did not elicit any severe adverse event. Patients receiving active treatment displayed an initial increase in allergen-specific IgE level and peripheral T-cell activation. A clinical improvement in nasal allergic symptoms upon challenge was recorded along with a decreased inflammatory response in the nose. In addition, these patients reported an improvement in their seasonal allergic disease. No such changes were seen in the placebo group. Although this study is based on a limited number of patients, ILIT with grass-pollen or birch-pollen extracts appears to reduce nasal allergic symptoms without causing any safety problems. Hence, ILIT might constitute a less time-consuming and more cost-effective alternative to conventional subcutaneous allergen-specific immunotherapy.

To investigate the cost-effectiveness of standardized specific immunotherapy (SIT) for allergic rhinitis patients accompanied with asthma (ARAS) in China. Forty ARAS patients sensitized with house dust mite (HDM) were administered with SIT (SIT group) or merely medicine treatment (control group). Alutard dermatophagoides pteronyssinus vaccine from ALK company was used for immunotherapy. The usage of symptom control medicine was according to the ARIA and GINA guideline. Cost-effectiveness ratio (CER) and Incremental cost-effectiveness ratio(ICER) analysis was conducted. The effectiveness was measured in terms of symptom scores, quality of life, objective improvement of rhinitis and asthma. Sensitive analysis was conducted to verify the stability of the results. The cost of SIT group for 1 year (6578 yuan) was higher than that of control group (1733.3 yuan), while the cost-effectiveness ratio and incremental cost-effectiveness ratio of SIT group were significant better than that of control group in all items. CER was 1686.7 yuan in SIT group compared with 3466.6 yuan in control group for nasal symptom scores, 4698.6 yuan in SIT group compared with 5777.8 yuan in control group for asthma symptom scores, 3462.1 yuan in SIT group compared with 8666.7 yuan in control group. The sensitive analysis of the price 10 percent higher or lower showed the same results. The cost-effectiveness of specific immunotherapy (SIT) for mite sensitized ARAS patients was better than that of merely medicine treatment.

Respiratory infections cause high morbidity and mortality worldwide. This study aims to estimate the relationship between allergic respiratory diseases with the occurrence of recurrent respiratory infection (RRI) in children and adolescents. The International Study of Asthma and Allergies in Childhood questionnaire and a questionnaire that provides data on the history of respiratory infections and the use of antibiotics were used to obtain data from patients. The relationship between the presence of asthma or allergic rhinitis and the occurrence of respiratory infections in childhood was analyzed. We interviewed the caregivers of 531 children aged 0 to 15 years. The average age of participants was 7.43 years, with females accounting for 52.2%. This study found significant relationship between: presence of asthma or allergic rhinitis with RRI, with prevalence ratio (PR) of 2.47 (1.51-4.02) and 1.61 (1.34-1.93), respectively; respiratory allergies with use of antibiotics for respiratory problems, with PR of 5.32 (2.17-13.0) for asthma and of 1.64 (1.29-2.09) for allergic rhinitis; asthma and allergic rhinitis with diseases of the lower respiratory airways, with PR of 7.82 (4.63-13.21) and 1.65 (1.38-1.96), respectively. In contrast, no relationship between upper respiratory airway diseases and asthma and allergic rhinitis was observed, with PR of 0.71 (0.35-1.48) and 1.30 (0.87-1.95), respectively. RRI is associated with previous atopic diseases, and these conditions should be considered when treating children.

Parasitic helminths have been shown to reduce inflammation in most experimental models of allergic disease, and this effect is mediated via cytokine responses. However, in humans, the effects of controlled helminth infection on cytokine responses during allergy have not been studied. The aim was to investigate whether infection with the nematode parasite Trichuris suis alters systemic cytokine levels, cellular cytokine responses to parasite antigens and pollen allergens and/or the cytokine profile of allergic individuals. In a randomized double-blinded placebo-controlled clinical trial (UMIN trial registry, Registration no. R000001298, Trial ID UMIN000001070, URL: http://www.umin.ac.jp/map/english), adults with grass pollen-induced allergic rhinitis received three weekly doses of 2500 Trichuris suis ova (n = 45) or placebo (n = 44) over 6 months. IFN-γ, TNF-α, IL-4, IL-5, IL-10 and IL-13 were quantified via cytometric bead array in plasma. Cytokines, including active TGF-β, were also quantified in supernatants from peripheral blood mononuclear cells cultured with parasite antigens or pollen allergens before, during and after the grass pollen season for a sub-cohort of randomized participants (T. suis ova-treated, n = 12, Placebo-treated, n = 10). Helminth infection induced a Th2-polarized cytokine response comprising elevated plasma IL-5 and parasite-specific IL-4, IL-5 and IL-13, and a global shift in the profile of systemic cytokine responses. Infection also elicited high levels of the regulatory cytokine IL-10 in response to T. suis antigens. Despite increased production of T. suis-specific cytokines in T. suis ova-treated participants, allergen-specific cytokine responses during the grass pollen season and the global profile of PBMC cytokine responses were not affected by T. suis ova treatment. This study suggests that cytokines induced by Trichuris suis ova treatment do not alter allergic reactivity to pollen during the peak of allergic rhinitis

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.

Allergic and non-allergic rhinitis ranks among the common occupational health problems. However, data on the incidence of occupational rhinitis are lacking, since comprehensive studies are rare. The study includes a group of patients in the Slovak Republic who were reported as having occupational rhinitis in the years 1990-2011. The following parameters were tracked in the investigated sample: age, gender, number of cases by individual years, occupations, causative factors and the length of exposure to the given agent. Possible progression of rhinitis to bronchial asthma was evaluated as well. The diagnostic algorithm was also analysed retrospectively, which included skin tests, the examination of specific IgE antibodies and nasal provocation tests. A total of 70 cases of occupational rhinitis were reported. The disease most often occurred in food industry workers (50% of cases). The most common aetiological factor was flour. Among other relatively common allergens were synthetic textile, wool, cotton and different types of moulds. Significant agents were also different chemical factors causing allergic and irritant rhinitis. The average length of exposure was 14.8 years. Exposure was shorter in men than in women (11 years vs. 16 years) (p = 0.04). Bronchial asthma as a comorbidity was diagnosed in 13 patients (19.7%). The critical diagnostic method on the basis of which the causal association between rhinitis and work environments was confirmed in 59% of cases was skin test; confirmation of the occupational cause using nasal provocation test was less frequent (18%). Food industry, textile industry and agriculture were the most risky occupational environments. Workers in these sectors require preventive intervention. In case of showing rhinitis symptoms it is necessary to confirm the occupational aetiology of the disease by the objective diagnostic methods. Since occupational rhinitis mostly precedes the occupational asthma, the elimination from the workplace is

This study aimed to investigate the effects of aromatherapy oil inhalation on symptoms, quality of life, sleep quality, and fatigue level among adults with perennial allergic rhinitis (PAR). Fifty-four men and women aged between 20 and 60 were randomized to inhale aromatherapy oil containing essential oil from sandalwood, geranium, and Ravensara or almond oil (the placebo) for 5 minutes twice daily for 7 days. PAR symptoms determined by Total Nasal Symptom Score (TNSS), the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), sleep quality by Verran Synder-Halpern (VSH) scale, and fatigue level by Chalder Fatigue Scale (CFS) were assessed before and after intervention period. Compared with the placebo, the experimental group showed significant improvement in TNSS, especially in nasal obstruction. The aromatherapy group also showed significantly higher improvements in total score of RQLQ and CFS. These findings indicate that inhalation of certain aromatherapy oil helps relieve PAR symptoms, improve rhinitis-specific quality of life, and reduce fatigue in patients with PAR. In conclusion, inhalation of aromatherapy essential oil may have potential as an effective intervention to alleviate PAR.

The march from early aeroallergen sensitization to subsequent respiratory allergy is well established, but it is unclear whether early life food sensitization precedes and further increases risk of allergic airway disease. To assess the association between food sensitization in the first 2 years of life and subsequent asthma and allergic rhinitis by age 10-12 years. We used data from two independent cohorts: the high-risk Melbourne Atopic Cohort Study (MACS) (n = 620) and the population-based LISAplus (n = 3094). Food sensitization was assessed at 6, 12, and 24 months in MACS and 24 months in LISAplus. Multiple logistic regressions were used to estimate associations between sensitization to food only, aeroallergen only, or both and allergic airway disease. When compared to non-sensitized children, sensitization to food only at 12 months in MACS and 24 months in LISAplus was associated with increased risk of current asthma (aOR = 2.2; 95% CI 1.1, 4.6 in MACS and aOR = 4.9; 2.4, 10.1 in LISAplus). Similar results were seen for allergic rhinitis. Additionally, cosensitization to food and aeroallergen in both cohorts at any tested point was a stronger predictor of asthma (at 24 months, aOR = 8.3; 3.7, 18.8 in MACS and aOR = 14.4; 5.0, 41.6 in LISAplus) and allergic rhinitis (at 24 months, aOR = 3.9; 1.9, 8.1 in MACS and aOR = 7.6; 3.0, 19.6 in LISAplus). In both cohorts, food sensitization (with or without aeroallergen sensitization) in the first two years of life increased the risk of subsequent asthma and allergic rhinitis. These findings support the role of early life food sensitization in the atopic march and suggest trials to prevent early onset have the potential to reduce the development of allergic airways disease. © 2016 John Wiley & Sons A/S.

Acute Rhinitis is based on an inflammation of the nasal mucous membrane with nasal discharge and obstruction. Symptomatic treatment includes local application of decongestants as Xylometazoline and epithelia-protective agents as Dexpanthenol. After proving a synergistic effect of Xylometazoline and Dexpanthenol (Nasic) in patients after nasal surgery, this result should be checked in patients with acute non-allergic rhinitis. Randomised verum controlled double-blind parallel-group-comparison of five days treatment with nasal sprays containing the combination of Xylometazolin-Dexpanthenol or Xylometazolin. The assessments of nasal obstruction, rhinorrhea, hyperplasia of nasal concha and redness of the nasal mucous membrane were defined as main-target parameters. 152 outpatients diagnosed with non-allergic, acute rhinitis were included in this study. 151 patients completed the study according to protocol. The superiority of the treatment with Xylometazolin-Dexpanthenol could be proven for the main outcome measures in comparison to Xylometazolin clinically relevant and statistically significant. The result was also validated by the secondary endpoints. The clinically proven efficacy is emphasized by the rhinoscopic findings and safety parameters showing a better tolerability of the combination. Accelerating the wound healing corroborates the superiority of the combination and is due to the epithelia protective effect of Dexpanthenol. These results allow especially under socio-economic points of view the conclusion that shorter treatment time with a diminishing risk of a "rebound effect" will improve compliance.

Allergic rhinitis (also known as hay fever) is the most commonly occurring immunological disorder, and it affects 40 million men, women, and children in the United States. Symptomatically, it is an inflammation and irritation of the mucous membranes that line the nose. Allergy is defined as a state of hypersensitivity or hyperimmunity caused by exposure to a particular antigen (allergen) that results in increased reactivity upon subsequent exposure. A novel botanical formulation, Aller-7/NR-A2, was developed for the treatment of allergic rhinitis; it is a combination of medicinal plant extracts from Phyllanthus emblica, Terminalia chebula, Terminalia bellerica, Albizia lebbeck, Piper nigrum, Zingiber officinale, and Piper longum. This novel formulation has demonstrated potent antihistaminic, anti-inflammatory, antispasmodic, antioxidant, and mast-cell-stabilization activities. All of the doses for these toxicity studies were selected according to the guidelines of the Organization for Economic Cooperation and Development, the World Health Organization, and the Environmental Protection Agency. Acute toxicity of Aller-7 was evaluated in Swiss Albino mice at doses of 125, 250, 500, 1000, and 1500 mg/kg. After 15 days of treatment, the animals were sacrificed. No histopathological changes were observed in major vital organs. A similar study was conducted in Albino Wistar rats, which were sacrificed at the end of 15 days. No histopathological changes or toxicity was observed at up to 2 g/kg body weight. Subacute toxicity was conducted in Albino Wistar rats at a dose of 90 mg/kg body weight for 3 days, then at 180 mg/kg for the next 3 days, and then at 270 mg/kg for 3 weeks. After 28 days, the animals were sacrificed and tested; no toxicity was observed. In a subchronic toxicity study, there was no observed adverse effect level at 1 g/kg body weight in rats. In a teratological assay, at doses of 3.0 g/kg (20 times the recommended dose) and 1.8 g/kg, respectively, no

Purpose: Accumulating evidence has shown that allergic diseases are caused by a complex interaction of genetic and environmental factors, some single nucleotide polymorphisms (SNPs) existing in high-affinity IgE receptor β chain (FcεRIβ) are potential risk factors for allergic diseases. However, the results have been inconsistent and inconclusive due to the limited statistical power in individual study. Thus, we conducted a meta-analysis to systematically evaluate the association between FcεRIβ SNPs and allergic diseases risk. Methods: Eligible studies were collected from PubMed, Embase, Web of Science, CNKI, and WanFang databases. Pooled odd ratios (ORs) and corresponding 95% confidence intervals (95%CIs) were calculated to assess the strength of the relationships between five polymorphisms (E237G, -109 C/T, RsaI_in2, RsaI_ex7 and I181L) and the risk of allergic diseases by using five genetic models. In addition, the stability of our analysis was evaluated by publication bias, sensitivity and heterogeneity analysis. Results: Overall, a total of 29 case-control studies were included in this meta-analysis. We found that E237G (B vs. A: OR = 1.28, 95%CI = 1.06-1.53, P < 0.001, I 2 = 63.1%) and -109 C/T (BB vs. AA+AB: OR = 1.58, 95%CI = 1.26-1.98, P < 0.001, I 2 = 66.4%) were risk factors for allergic diseases. Conclusion : Our meta-analysis suggests that polymorphisms in FcεRIβ, may be associated with the development of allergic diseases. ©2018 The Author(s).

Bilastine is a novel, nonsedating H(1)-antihistamine developed for symptomatic treatment of Allergic Rhinitis and Chronic Idiopathic Urticaria. The objective of this study was to compare the efficacy and safety of bilastine 20 mg vs placebo and desloratadine 5 mg in subjects with seasonal allergic rhinitis (SAR). This randomized, double blind, placebo-controlled, parallel-group multicentre study evaluated the effect of 2 weeks' treatment with bilastine 20 mg, desloratadine 5 mg or matched placebo once daily, in 12-70 years old symptomatic SAR patients. All subjects assessed the severity of nasal (obstruction, rhinorrhoea, itching, and sneezing) and nonnasal (ocular itching, tearing, ocular redness, itching of ears and/or palate) symptoms on a predetermined scale to provide a total symptom score (TSS), composed of nasal and nonnasal symptom scores (NSS and NNSS, respectively). The primary efficacy measure was the area under the curve (AUC) for the TSS over the entire treatment period. Bilastine 20 mg significantly reduced the AUC of TSS to a greater degree from baseline compared to placebo (98.4 with bilastine vs 118.4 with placebo; P < 0.001), but not compared to desloratadine 5 mg (100.5). Bilastine 20 mg was not different from desloratadine 5 mg but significantly more effective than placebo in improving the NSS, NNSS, and rhinitis-associated discomfort scores (P < 0.05), and rhinoconjunctivitis quality of life questionnaire total (P < 0.005) and four out of seven individual domain (P < 0.05) scores. The incidence of treatment emergent adverse events was similar for bilastine (20.6%), desloratadine (19.8%), and placebo (18.8%). Bilastine 20 mg once daily was efficacious, safe and not different from desloratadine 5 mg once daily in the treatment of SAR symptoms.

Physical activity (PA) protects against most noncommunicable diseases and has been associated with decreased risk of allergic phenotype, which is increasing worldwide. However, the association is not always present; furthermore it is not clear whether it is strongest for asthma, rhinitis, symptoms of these, or atopic sensitization; which sex is most affected; or whether it can be explained by either avoidance of sport or exacerbation of symptoms by exercise. Interventions are thus difficult to target. PA was measured by one-week accelerometry in 1137 Germans (mean age 15.6 years, 47% boys) from the GINIplus and LISAplus birth cohorts, and modeled as a correlate of allergic symptoms, sensitization, or reported doctor-diagnosed asthma or rhinitis. 8.3% of children had asthma, of the remainder 7.9% had rhinitis, and of the remainder 32% were sensitized to aero-allergens (atopic). 52% were lung-healthy controls. Lung-healthy boys and girls averaged 46.4 min and 37.8 min moderate-to-vigorous PA per day, of which 14.6 and 11.4 min was vigorous. PA in allergic girls was not altered, but boys with asthma got 13% less moderate and 29% less vigorous PA, and those with rhinitis with 13% less moderate PA, than lung-healthy boys. Both sexes participated comparably in sport (70 to 84%). Adolescents with wheezing (up to 68%, in asthma) and/or nose/eye symptoms (up to 88%, in rhinitis) were no less active. We found that asthma and rhinitis, but not atopy, were independently associated with low PA in boys, but not in girls. These results indicate that allergic boys remain a high-risk group for physical inactivity even if they participate comparably in sport. Research into the link between PA and allergy should consider population-specific and sex-specific effects, and clinicians, parents, and designers of PA interventions should specifically address PA in allergic boys to ensure full participation.

Large observational implementation studies are needed to triangulate the findings from randomized control trials as they reflect "real-world" everyday practice. In a pilot study, we attempted to provide additional and complementary insights on the real-life treatment of allergic rhinitis (AR) using mobile technology. A mobile phone app (Allergy Diary, freely available in Google Play and Apple App stores) collects the data of daily visual analog scales (VAS) for (i) overall allergic symptoms, (ii) nasal, ocular, and asthma symptoms, (iii) work, as well as (iv) medication use using a treatment scroll list including all medications (prescribed and over the counter (OTC)) for rhinitis customized for 15 countries. A total of 2871 users filled in 17 091 days of VAS in 2015 and 2016. Medications were reported for 9634 days. The assessment of days appeared to be more informative than the course of the treatment as, in real life, patients do not necessarily use treatment on a daily basis; rather, they appear to increase treatment use with the loss of symptom control. The Allergy Diary allowed differentiation between treatments within or between classes (intranasal corticosteroid use containing medications and oral H1-antihistamines). The control of days differed between no [best control], single, or multiple treatments (worst control). This study confirms the usefulness of the Allergy Diary in accessing and assessing everyday use and practice in AR. This pilot observational study uses a very simple assessment (VAS) on a mobile phone, shows novel findings, and generates new hypotheses. © 2018 EAACI and John Wiley and Sons A/S.

WHO guidelines advocate breastfeeding for 6 months, and EAACI guideline recommends exclusive breastfeeding for 4-6 months. However, evidence for breastfeeding to prevent asthma and allergic disease is conflicting. We examined whether following recommended breastfeeding guidelines alters the long-term risks of asthma, eczema, rhinitis or atopy. The effect of nonexclusive (0, >0-6, >6 months) and exclusive breastfeeding (0, >0-4, >4 months) on repeated measures of asthma (10, 18 years), eczema, rhinitis, and atopy (1-or-2, 4, 10, 18 years) risks was estimated in the IoW cohort (n = 1456) using log-linear models with generalized estimating equations. The Food Allergy and Intolerance Research (FAIR) cohort (n = 988), also from the IoW, was examined to replicate results. Breastfeeding (any or exclusive) had no effect on asthma and allergic disease in the IoW cohort. In the FAIR cohort, any breastfeeding for >0-6 months protected against asthma at 10 years (RR = 0.50, 95% CI = 0.32-0.79, P = 0.003), but not other outcomes, whilst exclusive breastfeeding for >4 months protected against repeated rhinitis (RR = 0.36, 95% CI = 0.18-0.71, P = 0.003). Longer breastfeeding was protective against late-onset wheeze in the IoW cohort. The protective effects of nonexclusive and exclusive breastfeeding against long-term allergic outcomes were inconsistent between these colocated cohorts, agreeing with previous observations of heterogeneous effects. Although breastfeeding should be recommended for other health benefits, following breastfeeding guidelines did not appear to afford a consistent protection against long-term asthma, eczema, rhinitis or atopy. Further research is needed into the long-term effects of breastfeeding on allergic disease. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Selecting the optimal oral antihistamine for patients with allergic rhinitis.

PubMed

Lehman, Jeffrey M; Blaiss, Michael S

2006-01-01

Allergic rhinitis (AR) is now recognised as a global health problem that affects 10-30% of adults and up to 40% of children. Each year, millions of patients seek treatment from their healthcare provider. However, the prevalence of AR maybe significantly underestimated because of misdiagnosis, under diagnosis and failure of patients to seek medical attention. In addition to the classical symptoms such as sneezing, nasal pruritus, congestion and rhinorrhoea, it is now recognised that AR has a significant impact on quality of life (QOL). This condition can lead to sleep disturbance as a result of nasal congestion, which leads to significant impairment in daily activities such as work and school. Traditionally, AR has been subdivided into seasonal AR (SAR) or perennial AR (PAR). SAR symptoms usually appear during a specific season in which aeroallergens are present in the outdoor air such as tree and grass pollen in the spring and summer and weed pollens in the autumn (fall); and PAR symptoms are present year-round and are triggered by dust mite, animal dander, indoor molds and cockroaches. Oral histamine H(1)-receptor antagonists (H(1) antihistamines) are one of the most commonly prescribed medications for the treatment of AR. There are several oral H(1) antihistamines available and it is important to know the pharmacology, such as administration interval, onset of action, metabolism and conditions that require administration adjustments. When prescribing oral H(1) antihistamines, the healthcare provider must take into account the clinical efficacy and weigh this against the risk of adverse effects from the agent. In addition to the clinical efficacy, potential for improvement in QOL with a particular treatment should also be considered.

Rhinitis and sleep disorders: The trigeminocardiac reflex link?

PubMed

Bindu, Barkha; Singh, Gyaninder Pal; Chowdhury, Tumul; Schaller, Bernhard

Rhinitis, allergic or non-allergic, is an inflammatory condition of the nose. It is associated with a wide range of sleep disorders that are generally attributed to nasal congestion and presence of inflammatory mediators like cytokines and interleukins. However, the pathophysiological mechanisms behind these sleep disorders remain unclear. On the other hand, the trigeminocardiac reflex (TCR) has recently been linked to various sleep disorders like obstructive sleep apnea, sleep bruxism and rapid eye movement (REM) sleep apnea. TCR can be incited by stimulation of the trigeminal nerve or the area innervated by its branches including the nasal mucosa. Trigeminal nasal afferents can be activated on exposure to noxious stimuli (mechanical or chemical) like ammonia vapors, carbon-dioxide, nicotine, hypertonic saline, air-puffs and smoke. In rhinitis, there is associated neuronal hyper-responsiveness of sensory nasal afferents due to inflammation (which can be suppressed by steroids). This may further lead to increased occurrence of TCR in rhinitis. Moreover, there is involvement of autonomic nervous system both in rhinitis and TCR. In TCR, parasympathetic over activity and sympathetic inhibition leads to sudden onset bradycardia, hypotension, apnea and gastric motility. Also, the autonomic imbalance reportedly plays a significant role in the pathophysiology of rhinitis. Thus, considering these facts we hypothesize that the TCR could be the link between rhinitis and sleep disorders and we believe that further research in this direction may yield significant development in our understanding of sleep disorders in rhinitis.

This report has been prepared by the European Academy of Allergy and Clinical Immunology Task Force on Allergic Rhinitis (AR) comorbidities. The aim of this multidisciplinary European consensus document is to highlight the role of multimorbidities in the definition, classification, mechanisms, recommendations for diagnosis and treatment of AR, and to define the needs in this neglected area by a literature review. AR is a systemic allergic disease and is generally associated with numerous multi-morbid disorders, including asthma, eczema, food allergies, eosinophilic oesophagitis (EoE), conjunctivitis, chronic middle ear effusions, rhinosinusitis, adenoid hypertrophy, olfaction disorders, obstructive sleep apnea, disordered sleep and consequent behavioural and educational effects. This report provides up-to-date usable information to: (1) improve the knowledge and skills of allergists, so as to ultimately improve the overall quality of patient care; (2) to increase interest in this area; and (3) to present a unique contribution to the field of upper inflammatory disease.

1 Five years' experience in the use of beclomethasone dipropionate aerosol (BDA) in the treatment of 315 patients with upper respiratory tract allergy is reviewed. 2 A total of 223 patients with perennial rhinitis was treated. In 23, where the nasal allergy had recurred after oral corticosteroid therapy for asthma was withdrawn, BDA was effective in 69% of cases. A similar success rate (68%) was recorded in 169 patients suffering from perennial allergic rhinitis alone, but a satisfactory response was observed in only 45% of 31 patients with nasal polypi. 3 In 92 patients with seasonal allergic rhinitis freedom from symptoms was achieved in 80%. 4 A total of approximately 534 patient-years of treatment has been recorded without any evidence of side-effects either clinically or on nasal biopsy.

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.

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/m 3 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.

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.

Valuing the Economic Costs of Allergic Rhinitis, Acute Bronchitis, and Asthma from Exposure to Indoor Dampness and Mold in the US

PubMed Central

2016-01-01

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.

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.

There are consistent findings on associations between asthma and allergy symptoms and residential mold and moisture. However, definitions of 'dampness' in studies are diverse because of differences in climate and building construction. Few studies have estimated mold problems inside the building structure by odor assessments. In a nested case-control study of 400 Swedish children, observations and measurements were performed in their homes by inspectors, and the children were examined by physicians for diagnoses of asthma, eczema, and rhinitis. In conclusion, we found an association between moldy odor along the skirting board and allergic symptoms among children, mainly rhinitis. No associations with any of the allergic symptoms were found for discoloured stains, 'floor dampness' or a general mold odor in the room. A moldy odor along the skirting board can be a proxy for hidden moisture problem inside the outer wall construction or in the foundation construction. There are indications that such dampness problems increase the risk for sensitization but the interpretation of data in respect of sensitization is difficult as about 80% of the children with rhinitis were sensitized. Furthermore, low ventilation rate in combination with moldy odor along the skirting board further increased the risk for three out of four studied outcomes, indicating that the ventilation rate is an effect modifier for indoor pollutants. This study showed that mold odor at the skirting board level is strongly associated with allergic symptoms among children. Such odor at that specific place can be seen as a proxy for some kind of hidden moisture or mold problem in the building structure, such as the foundation or wooden ground beam. In houses with odor along the skirting board, dismantling of the structure is required for an investigation of possible moisture damage, measurements, and choice of actions. In homes with low ventilation in combination with mold odor along the skirting board

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.

Allergic disease may be increased by climate change. Recent reports have shown that typhoon and heavy rain increase allergic disease locally by concentration of airborne allergens of pollen, ozone, and fungus, which are causes of allergic disease. The objective of this study was to determine whether typhoon and heavy rain increase allergic disease in Korea. This study included allergic disease patients of the area declared as a special disaster zone due to storms and heavy rains from 2003 to 2009. The study used information from the Korea Meteorological Administration, and from the National Health Insurance Service for allergic diseases (asthma, allergic rhinitis, and atopic dermatitis). During a storm period, the numbers of allergy rhinitis and atopic dermatitis outpatients increased [rate ratio (RR) = 1.191; range, 1.150-1.232] on the sixth lag day. However, the number of asthma outpatients decreased (RR = 0.900; range, 0.862-0.937) on the sixth lag day after a disaster period. During a storm period, the numbers of allergic rhinitis outpatients (RR = 1.075; range, 1.018-1.132) and atopy outpatients increased (RR = 1.134; range, 1.113-1.155) on the seventh lag day. However, the number of asthma outpatients decreased to RR value of 0.968 (range, 0.902-1.035) on the fifth lag day. This study suggests that typhoon and heavy rain increase allergic disease apart from asthma. More study is needed to explain the decrease in asthma.

Background Although allergen specific immunotherapy (SIT) represents the only immune- modifying and curative option available for patients with allergic rhinitis (AR), the optimal schedule for specific subcutaneous immunotherapy (SCIT) is still unknown. The objective of this study is to systematically assess the efficacy and safety of cluster SCIT for patients with AR. Methods By searching PubMed, EMBASE and the Cochrane clinical trials database from 1980 through May 10th, 2013, we collected and analyzed the randomized controlled trials (RCTs) of cluster SCIT to assess its efficacy and safety. Results Eight trials involving 567 participants were included in this systematic review. Our meta-analysis showed that cluster SCIT have similar effect in reduction of both rhinitis symptoms and the requirement for anti-allergic medication compared with conventional SCIT, but when comparing cluster SCIT with placebo, no statistic significance were found in reduction of symptom scores or medication scores. Some caution is required in this interpretation as there was significant heterogeneity between studies. Data relating to Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) in 3 included studies were analyzed, which consistently point to the efficacy of cluster SCIT in improving quality of life compared to placebo. To assess the safety of cluster SCIT, meta-analysis showed that no differences existed in the incidence of either local adverse reaction or systemic adverse reaction between the cluster group and control group. Conclusion Based on the current limited evidence, we still could not conclude affirmatively that cluster SCIT was a safe and efficacious option for the treatment of AR patients. Further large-scale, well-designed RCTs on this topic are still needed. PMID:24489740

General anesthesia (GA) has been used for second line treatment strategy for status asthmaticus in pediatric patients. The association between GA in children and risk of followed-up allergic diseases is unclear. This study aims to assess the risk of allergic diseases after GA in children.We did a nationwide retrospective cohort study by analyzing data from the National Health Insurance Research Database (NHIRD) in Taiwan. The subsequent risks for allergic diseases, including asthma (ICD-9: 493.X), allergic rhinitis (AR; ICD-9 CM code 477.X), and atopic dermatitis (AD; ICD-9-CM code 691.X), were compared between exposure to GA and none before 1 year of age throughout the follow-up period using the Cox proportional hazards model.Insurance claims data for 32,742 children younger than 1 year old from all insured children in the NHIRD. Of those, 2358 subjects were exposed to GA; 414 and 1944 children exposed to mask and intubation ventilation, respectively, served as the study cohort, whereas the remaining 30,384 children made up the comparison cohort. Children in the GA group were at a lower risk of developing asthma, AR and AD, with adjusted hazard ratios of 0.67 (0.62-0.72, 95%CI), 0.72 (0.68-0.77, 95%CI), 0.60 (0.56-0.64, 95%CI), respectively.Children who were exposed to GA in early life before 1 year of age had reduced risk of subsequently developing allergic diseases such as asthma, AD, and AR, when compared with general population.

Timing of introduction of allergenic foods to the infant diet may influence the risk of allergic or autoimmune disease, but the evidence for this has not been comprehensively synthesized. To systematically review and meta-analyze evidence that timing of allergenic food introduction during infancy influences risk of allergic or autoimmune disease. MEDLINE, EMBASE, Web of Science, CENTRAL, and LILACS databases were searched between January 1946 and March 2016. Intervention trials and observational studies that evaluated timing of allergenic food introduction during the first year of life and reported allergic or autoimmune disease or allergic sensitization were included. Data were extracted in duplicate and synthesized for meta-analysis using generic inverse variance or Mantel-Haenszel methods with a random-effects model. GRADE was used to assess the certainty of evidence. Wheeze, eczema, allergic rhinitis, food allergy, allergic sensitization, type 1 diabetes mellitus, celiac disease, inflammatory bowel disease, autoimmune thyroid disease, and juvenile rheumatoid arthritis. Of 16 289 original titles screened, data were extracted from 204 titles reporting 146 studies. There was moderate-certainty evidence from 5 trials (1915 participants) that early egg introduction at 4 to 6 months was associated with reduced egg allergy (risk ratio [RR], 0.56; 95% CI, 0.36-0.87; I2 = 36%; P = .009). Absolute risk reduction for a population with 5.4% incidence of egg allergy was 24 cases (95% CI, 7-35 cases) per 1000 population. There was moderate-certainty evidence from 2 trials (1550 participants) that early peanut introduction at 4 to 11 months was associated with reduced peanut allergy (RR, 0.29; 95% CI, 0.11-0.74; I2 = 66%; P = .009). Absolute risk reduction for a population with 2.5% incidence of peanut allergy was 18 cases (95% CI, 6-22 cases) per 1000 population. Certainty of evidence was downgraded because of imprecision of effect estimates and

There is growing evidence for an increase in food allergies. The question of whether early life food sensitization, a primary step in food allergies, leads to other allergic disease is a controversial but important issue. Birth cohorts are an ideal design to answer this question. We aimed to systematically investigate and meta-analyse the evidence for associations between early food sensitization and allergic disease in birth cohorts. MEDLINE and SCOPUS databases were searched for birth cohorts that have investigated the association between food sensitization in the first 2 years and subsequent wheeze/asthma, eczema and/or allergic rhinitis. We performed meta-analyses using random-effects models to obtain pooled estimates, stratified by age group. The search yielded fifteen original articles representing thirteen cohorts. Early life food sensitization was associated with an increased risk of infantile eczema, childhood wheeze/asthma, eczema and allergic rhinitis and young adult asthma. Meta-analyses demonstrated that early life food sensitization is related to an increased risk of wheeze/asthma (pooled OR 2.9; 95% CI 2.0-4.0), eczema (pooled OR 2.7; 95% CI 1.7-4.4) and allergic rhinitis (pooled OR 3.1; 95% CI 1.9-4.9) from 4 to 8 years. Food sensitization in the first 2 years of life can identify children at high risk of subsequent allergic disease who may benefit from early life preventive strategies. However, due to potential residual confounding in the majority of studies combined with lack of follow-up into adolescence and adulthood, further research is needed. © 2015 John Wiley & Sons A/S.

Methods A total of 3,124 children aged 1–2 years were included in the Dampness in Building and Health (DBH) study in the year 2000, and followed up 5 years later by a parental questionnaire based on an International Study of Asthma and Allergies in Childhood protocol. The association between eczema in early childhood and the incidence of asthma and rhinitis later in life was estimated by univariable and multivariable logistic regression modelling. Results The prevalence of eczema in children aged 1–2 years was 17.6% at baseline. Children with eczema had a 3-fold increased odds of developing asthma (adjusted odds ratio [aOR], 3.07; 95% confidence interval (CI) 1.79–5.27), and a nearly 3-fold increased odds of developing rhinitis (aOR, 2.63; 1.85–3.73) at follow-up compared with children without eczema, adjusted for age, sex, parental allergic disease, parental smoking, length of breastfeeding, site of living, polyvinylchloride flooring material, and concomitant allergic disease. When eczema was divided into subgroups, moderate to severe eczema (aOR, 3.56; 1.62–7.83 and aOR, 3.87; 2.37–6.33, respectively), early onset of eczema (aOR, 3.44; 1.94–6.09 and aOR, 4.05; 2.82–5.81; respectively), and persistence of eczema (aOR, 5.16; 2.62–10.18 and aOR, 4.00; 2.53–6.22, respectively) further increased the odds of developing asthma and rhinitis. Further independent risk factors increasing the odds of developing asthma were a parental history of allergic disease (aOR, 1.83; 1.29–2.60) and a period of breast feeding shorter than 6 months (aOR, 1.57; 1.03–2.39). The incidence of rhinitis was increased for parental history of allergic disease (aOR, 2.00; 1.59–2.51) and polyvinylchloride flooring (aOR, 1.60; 1.02–2.51). Conclusion Eczema in infancy is associated with development of asthma and

The aim of this study was to analyze gene expression profiles for exploring the function and regulatory network of differentially expressed genes (DEGs) in pathogenesis of rhinitis by a bioinformatics method. The gene expression profile of GSE43523 was downloaded from the Gene Expression Omnibus database. The dataset contained 7 seasonal allergic rhinitis samples and 5 non-allergic normal samples. DEGs between rhinitis samples and normal samples were identified via the limma package of R. The webGestal database was used to identify enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of the DEGs. The differentially co-expressed pairs of the DEGs were identified via the DCGL package in R, and the differential co-expression network was constructed based on these pairs. A protein-protein interaction (PPI) network of the DEGs was constructed based on the Search Tool for the Retrieval of Interacting Genes database. A total of 263 DEGs were identified in rhinitis samples compared with normal samples, including 125 downregulated ones and 138 upregulated ones. The DEGs were enriched in 7 KEGG pathways. 308 differential co-expression gene pairs were obtained. A differential co-expression network was constructed, containing 212 nodes. In total, 148 PPI pairs of the DEGs were identified, and a PPI network was constructed based on these pairs. Bioinformatics methods could help us identify significant genes and pathways related to the pathogenesis of rhinitis. Steroid biosynthesis pathway and metabolic pathways might play important roles in the development of allergic rhinitis (AR). Genes such as CDC42 effector protein 5, solute carrier family 39 member A11 and PR/SET domain 10 might be also associated with the pathogenesis of AR, which provided references for the molecular mechanisms of AR.

Allergic rhinitis often impairs social life and performance. The aim of this cross-sectional study was to use cell phone data to assess the impact on work productivity of uncontrolled rhinitis assessed by visual analogue scale (VAS). A mobile phone app (Allergy Diary, Google Play Store and Apple App Store) collects data from daily visual analogue scales (VAS) for overall allergic symptoms (VAS-global measured), nasal (VAS-nasal), ocular (VAS-ocular) and asthma symptoms (VAS-asthma) as well as work (VAS-work). A combined nasal-ocular score is calculated. The Allergy Diary is available in 21 countries. The app includes the Work Productivity and Activity Impairment Allergic Specific Questionnaire (WPAI:AS) in six EU countries. All consecutive users who completed the VAS-work from 1 June to 31 October 2016 were included in the study. A total of 1136 users filled in 5818 days of VAS-work. Symptoms of allergic rhinitis were controlled (VAS-global <20) in approximately 60% of the days. In users with uncontrolled rhinitis, approximately 90% had some work impairment and over 50% had severe work impairment (VAS-work >50). There was a significant correlation between VAS-global calculated and VAS-work (Rho=0.83, P<0.00001, Spearman's rank test). In 144 users, there was a significant correlation between VAS-work and WPAI:AS (Rho=0.53, P<0.0001). This pilot study provides not only proof-of-concept data on the work impairment collected with the app but also data on the app itself, especially the distribution of responses for the VAS. This supports the interpretation that persons with rhinitis report both the presence and the absence of symptoms. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

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.
