Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) with and without nasal polyposis is a chronic inflammatory disease of the sinuses and nasal mucosa. Recent evidence has indicated a relationship between serum 25-hydroxyl vitamin D (OH-VitD) deficiency and CRS. Regarding this, the present study aimed to compare the serum level of 25-OH-VitD in CRS patients with and without nasal polyposis and control groups. MATERIALS AND METHODS This study was conducted on 117 adult subjects in three groups of CRS with nasal polyposis (CRSwNP; n=32), CRS without nasal polyposis (CRSsNP; n=35), and healthy controls (n=50). The mean level of serum 25-OH-VitD in the three groups was measured by means of enzyme- linked immunosorbent assay. The data were analyzed using SPSS software (version 18). RESULTS Mean serum levels of 25-OH-VitD in CRSwNP, CRSsNP, and control groups were 12.52, 15.54, and 22.04 ng/ml, respectively. There was a significant difference between the case and control groups in terms of 25-OH-VitD level (P=0.0001). However, no significant difference was observed between the CRSwNP and CRSsNP groups in this regard (P=0.464). The women had a VitD deficiency odds ratio (OR) of 2.47, compared with men (OR=2.47, 95% CI=1.04-5.86). The OR of VitD deficiency with aging was obtained as 0.957 (95% CI=0.925-0.989). In this regard, older patients had a lower probability of VitD deficiency, compared to younger patients. CONCLUSION As the findings indicated, serum 25-OH-VitD was significantly lower in CRS patients, compared with that in the non-CRS subjects.

Abstract
Chronic cough is one of the most common and troublesome nonspecific respiratory symptom for which patients seek a general practitioner and specialist advice. It is conventionally defined as a cough lasting for more than 8 weeks. Exhaled nitric oxide has proven to be a specific biomarker capable to discriminate between differential diagnoses of chronic cough and simultaneously provide information about the response to specific treatment. In this review, we will discuss the potential use of exhaled and nasal nitric oxide in the diagnosis of chronic chough.

Abstract
Background Japanese cedar pollinosis (JCP) is one of the most prevalent allergies in Japan. Within the past few decades, many food factors have been demonstrated to suppress symptoms of pollinosis and mast cell degranulation directly or indirectly. Herein, we conducted a study to clarify the anti-allergic potency of a fermented plant product (FPP) in JCP model mice. Methods Mice were administered FPP, 10-fold-diluted FPP, or saline every day for 40 days by oral gavage and sensitized with major Japanese cedar pollen allergens (SBP). The numbers of sneezes were counted for 5 minutes after SBP nasal challenge. We analyzed the SBP-specific immunoglobulin titers, serum concentration of mast cell protease 1, and cytokine production from splenocytes stimulated with SBP. Results The numbers of sneezes by the mice administered FPP were significantly suppressed compared to those administered saline. The 10-fold-diluted FPP also suppressed the number of sneezes compared to saline, although not significantly. Serum level of mast cell protease 1 tended to be suppressed in FPP-consumed mice compared to those in saline-treated mice. The SBP-specific immunoglobulin titers and cytokine production were comparable among the groups. Conclusions Our results suggest that FPP intake could attenuate JCP symptoms without change of systemic immune responses.

Abstract
BACKGROUND Allergen immunotherapy has proved effective in the treatment of various allergies, but whether the clinical benefits outweigh the economic costs has been little evaluated. OBJECTIVE To explore the economic consequences of immunotherapy in asthma, rhinitis and dermatitis. METHODS Descriptive study. Patients with at least 18 months' follow-up were selected, whose medical history allowed evaluation of drugs received, manner of use, check-ups, treatment changes, reasons for these, and so on. Patients were classified according to whether they received drug treatment + immunotherapy (active group) or drug therapy alone (control group). RESULTS 1848 patients were included: 648 in the active group and 1200 in the control. Immunotherapy increased the cost of treatment during the first few months, but after 9 to 12 months drug treatment decreased significantly compared to the control group. In patients with asthma or various diseases, immunotherapy reduced costs of treatment (p < 0.05). The active group saw fewer relapses at 18 months (p < 0.05). CONCLUSION Allergen immunotherapy allows the sustained reduction in drug treatment, with medium-term financial savings for the patient and the health system.

Abstract
Background In addition to allergen-specific IgE (sIgE), allergen-specific IgG4 (sIgG4) antibodies are also involved in the immune response resulting from an allergen exposure. The aim of our study was to analyze sIgE and sIgG4 patterns in the most common allergic disorders: bronchial asthma, upper airway disorders and atopic dermatitis. Methods In this study a screening analysis of blood serum samples from 673 patients aged from 6 months to 17 years with different allergic entities was performed on microarrays. sIgE and sIgG4 levels to the most common allergens were estimated. Results sIgE response to most pollen allergens is more strongly associated with respiratory diseases than with atopic dermatitis, while sIgE responses to cat and dog dander are more strongly associated with bronchial asthma than with atopic dermatitis and upper airway disorders such as rhinosinusitis and allergic rhinitis. A lower prevalence of sIgG4 to pollen allergens in cases of atopic dermatitis is observed compared with that in cases of asthma and upper airway disorders. Analyzing all the allergic disorders, one can see that sIgG4 response to inhalant allergens is strongly associated with sensitization to the corresponding allergen. Conclusion Allergen-specific IgE and IgG4 patterns that are relevant to concrete allergic diseases differ by sIgE and sIgG4 prevalences to defined allergens.

Abstract
The European Academy of Allergy and Clinical Immunology (EAACI) owns three journals: Allergy, Pediatric Allergy and Immunology and Clinical and Translational Allergy. One of the major goals of EAACI is to support health promotion in which prevention of allergy and asthma plays a critical role and to disseminate the knowledge of allergy to all stakeholders including the EAACI junior members. There was substantial progress in 2017 in the identification of basic mechanisms of allergic and respiratory disease and the translation of these mechanisms into clinics. Better understanding of molecular and cellular mechanisms, efforts for the development of biomarkers for disease prediction, novel prevention and intervention studies, elucidation of mechanisms of multimorbidies, entrance of new drugs in the clinics as well as recently completed phase three clinical studies and publication of a large number of allergen immunotherapy studies and metaanalyses have been the highlights of the last year.

Abstract
Studies in migrant populations provide vital opportunities to investigate the role of environmental factors in the pathogenesis of allergic disorders. Differences in allergy prevalence have been observed between migrants and native-born subjects living in the same geographical location. Immigrants who migrate from less affluent countries with lower allergy prevalence tend to have a lower prevalence of allergic disorders compared to native-born residents of the more affluent host country. The patterns of allergic disease prevalence also differ between first- and second-generation migrants. The timing of migration in relation to birth, age at migration, and duration of residence in the host country also influence one's atopic risk. A complex interplay of multiple environmental, socioeconomic, and cultural factors is likely responsible for these observed differences. Further research into the roles of various risk factors in modulating differences in allergic disease prevalence between migrant and native populations will enhance our understanding of the complex gene-environment interactions involved in the pathogenesis of allergic disorders.

Abstract
BACKGROUND Microbiota and human allergic airway diseases have been proven to be interrelated. Bacteria-derived extracellular vesicle (EV)s are known to play important roles in interbacterial and human-bacteria communications, but their relationship with allergies has not been examined yet. Urine EVs were investigated to determine whether they could be used as biomarkers for monitoring allergic airway diseases in children. METHODS Subjects were 4 groups of chronic rhinitis (CR), allergic rhinitis (AR), atopic asthma (AS) and healthy controls. Single voided urine samples were collected. Urine EVs were isolated and their DNA was extracted for 16S-rDNA pyrosequencing. RESULTS A total of 118 children participated in this study; 27, 39, 19, and 33 were in the CR, AR, AS, and control group, respectively. The AR had a significantly high Chao-1 index than that of controls. Principal component analysis revealed dysbiosis in the CR, AR, and AS compared to the controls. One phylum and 19 families and genera were significantly enriched or depleted in the disease groups compared to the controls; the Actinobacteria phylum and the Sphingomonadaceae family were more abundant in the AS and CR, the Comamonadaceae family, the Propionibacteraceae family, Propionibacterium and Enhydrobacter were more enriched in the CR, and the Methylobacteriaceae family and Methylobacterium were more abundant in each disease group, while the Enterobacteriaceae family was depleted in each disease group. CONCLUSIONS CR, AR, and AS had a distinct composition of urine EVs. Urine EVs could be an indicator for assessing allergic airway diseases in children.

Abstract
BACKGROUND Eosinophils are the principal effector cells involved in the pathogenesis of allergic rhinitis. Cell numbers increase in non-allergic rhinitis patients with eosinophilia, aspirin hypersensitivity and nasal polyposis, as well as in allergic rhinitis patients. Exfoliative nasal cytology can be used in the differential diagnosis of allergic rhinitis. OBJECTIVE To evaluate nasal eosinophilia in nasal smears of patients with mild, persistent and intermittent allergic rhinitis. METHODS The study comprised 60 patients with allergic rhinitis and 20 healthy volunteers. The patients were divided into intermittent and persistent allergic rhinitis groups. Nasal smear status, eosinophil numbers and Total Nasal Symptom Scores were compared. RESULTS Nasal smear results were pathological in 40 of 60 allergic rhinitis patients, which was significantly higher than the rate in controls. The mean nasal eosinophilia score was significantly higher in the intermittent allergic rhinitis than in the persistent allergic rhinitis group (p = 0.029). There was a positive correlation between nasal eosinophilia score and Total Nasal Symptom Score (r = 0.652; p < 0.05) in persistent allergic rhinitis and intermittent allergic rhinitis patients. CONCLUSION The nasal smear test is inexpensive, objective and simple to perform, and should be part of the diagnostic investigation.

Abstract
INTRODUCTION Eosinophilic mucin rhinosinusitis is a type of chronic rhinosinusitis (CRS). Diagnosis and treatment of this condition play a significant role in reducing the patients' clinical symptoms. This type of rhinosinusitis has a higher relapse rate, compared to the other types. This disease is more resistant to treatment and more dependent on corticosteroid therapy, compared to the other types of rhinosinusitis. Regarding this, the present study was designed to evaluate the frequency of eosinophilic mucin rhinosinusitis in patients undergoing sinus surgery in a tertiary referral center and examine some clinical and laboratory characteristics regarding this type of rhinosinusitis. MATERIALS AND METHODS This cross-sectional observational study was performed on patients over the age of 16 years, who were diagnosed with CRS in the otolaryngology clinic of a referral tertiary-level hospital, and were candidates for endoscopic sinus surgery. Based on the detection of eosinophilic mucin, the subjects were divided into two groups of eosinophilic mucin and non-eosinophilic mucin rhinosinusitis (controls). The groups were compared in terms of sino-nasal outcome test (SNOT-22) scores, Lund-Mackay staging scores, osteitis status, immunoglobulin E (IgE) level, and eosinophilia. RESULTS In this study, 46 subjects participated, 29 (63%) cases of whom had eosinophilic mucin. The SNOT-22 score and serum IgE level were significantly higher in the eosinophilic mucin group, compared to those in the control group. Osteitis and Lund-Mackay scores were also higher in the eosinophilic mucin group than those in the control group; however, this difference was not statistically significant. CONCLUSION Patients with eosinophilic mucin rhinosinusitis showed a more severe clinical involvement. Seemingly, the Iranian patients have a lower and higher frequency of eosinophilic mucin rhinosinusitis, compared to the patients from the Western countries and East Asia, respectively.

Abstract
mHealth, such as apps running on consumer smart devices is becoming increasingly popular and has the potential to profoundly affect healthcare and health outcomes. However, it may be disruptive and results achieved are not always reaching the goals. Allergic Rhinitis and its Impact on Asthma (ARIA) has evolved from a guideline using the best evidence-based approach to care pathways suited to real-life using mobile technology in allergic rhinitis (AR) and asthma multimorbidity. Patients largely use over-the-counter medications dispensed in pharmacies. Shared decision making centered around the patient and based on self-management should be the norm. Mobile Airways Sentinel networK (MASK), the Phase 3 ARIA initiative, is based on the freely available MASK app (the Allergy Diary, Android and iOS platforms). MASK is available in 16 languages and deployed in 23 countries. The present paper provides an overview of the methods used in MASK and the key results obtained to date. These include a novel phenotypic characterization of the patients, confirmation of the impact of allergic rhinitis on work productivity and treatment patterns in real life. Most patients appear to self-medicate, are often non-adherent and do not follow guidelines. Moreover, the Allergy Diary is able to distinguish between AR medications. The potential usefulness of MASK will be further explored by POLLAR (Impact of Air Pollution on Asthma and Rhinitis), a new Horizon 2020 project using the Allergy Diary.

Abstract
Background The aim of this study was to evaluate the positivity rates of atopy patch tests for Dermatophagoides pteronyssinus, Dermatophagoides farinae and Blomia tropicalis in patients with respiratory diseases such as asthma and allergic rhinitis with or without atopic dermatitis. Methods The patients’ clinical histories were collected, and the patients were subjected to skin prick and patch tests with the three different house dust mites on the same day. The patch tests were examined 48 hours later, and then patients were divided into two groups: I- patients with respiratory diseases, such as asthma and/or rhinitis, and atopic dermatitis and II-patients with only respiratory diseases. A total of 74 patients ranging in age from 2 to 60 years were included in this study; 16 patients were included in group I and 58 were included in group II. This study was approved by the human ethics committee of the Faculty of Medical Science and Health SUPREMA (number 2.007.135), and written informed consent was collected from each patient or their parents prior to enrollment. Results In the skin prick tests, the most prevalent mite that evoked a reaction was Dermatophagoides pteronyssinus, followed by Dermatophagoides farinae and Blomia tropicalis. Regarding the atopy patch tests, the mite that most frequently induced a positive reaction was Dermatophagoides farinae (78.4%), followed by Dermatophagoides pteronyssinus (77%) and Blomia tropicalis (52.7%). A comparison of the skin prick and atopy patch tests revealed that 53 patients (71.6%) were positive on both tests, and 30 (56.6%) patients were positivite for the same mite. We found six patients (8%) who had a positive clinical history of allergy and only exhibited positivity on the atopy patch test. Discussion Most studies have been performed with atopic dermatitis patients, but in this study, most of the patients had respiratory conditions. Blomia tropicalis is a mite that is prevalent in tropical areas, such as Brazil, and only two publications include these three mites, wich are present in Brazil. The APT may produce positive results in concordance with the SPT resuts, but may also be the only positive test ( 8%) as we observed in our study. These results suggest that the mite atopy patch test is relevant and should be considered as an additional test for patients with clinical histories of allergic respiratory disease who have negative prick test results. Conclusion The APT should be considered as an additional test when the SPT and specific serum IgE tests are negative in patients with clinical histories of allergies.

Abstract
PURPOSE OF REVIEW IgE is a key player in multiple inflammatory airway diseases. Ample literature demonstrates its presence in mucosa of patients with allergic rhinitis (AR), local allergic rhinitis (LAR), asthma, or chronic rhinosinusitis with nasal polyposis (CRSwNP). RECENT FINDINGS Current evidence shows that high-affinity IgE in blood stream of allergic individuals derives mainly from the mucosae. Also, mucosal synthesis of IgE can occur in the absence of systemic atopy, and may be relevant in atopic and non-atopic phenotypes of rhinitis as demonstrated in LAR. Specific IgE (sIgE) detection varies depending on technique used for sample collection and its measurement. sIgE detection is highly specific for diagnosis of LAR. Moreover, measurement of sIgE in secretions could be useful in monitoring response to allergen-specific immunotherapy in both AR and LAR phenotypes. This review will focus on recent developments in the role of IgE in respiratory diseases, and the clinical implications of its measurement in secretions.

Abstract
Background To assess the effects of Rhinosectan® spray, a medical device containing xyloglucan, on nasal ciliary function (in MucilAir™Nasal cells). Methods MucilAir™Nasal, a three-dimensional organotypic airway tissue model (with different cell types), was treated with Rhinosectan® (30 µl) or with a control (saline solution). The effects of Rhinosectan® were evaluated at 15 and 60 min post-exposure by: measurement of the cilia beating frequency (Hz), mucin detection (Enzyme-Linked Lectin Assay—ELLA), mucociliary clearance (µm/s) and phagocytosis assay (fluorescence). Results Exposure of MucilAir™ to Rhinosectan® did not alter the cilia beating frequency at 15 and 60 min post-exposure (diluted and undiluted). Exposure to Rhinosectan® (undiluted) during 60 min increased mucociliary clearance (93.3 ± 2.1 µm/s vs. 80.9 ± 1.8 µm/s; p < 0.01) and phagocytic activity (1.89-fold increase) in comparison with saline solution. Moreover, a significant decrease in mucin concentration was observed after 15 min of exposure (171.4 ng/ml vs. 306.5 ng/ml; p < 0.01) and at 60 min post-treatment (242.7 ng/ml vs. 339 ng/ml; p < 0.05). Conclusions The application of Rhinosectan® to nasal epithelial cells does not impair ciliary movement, enhances mucociliary clearance and facilitates phagocytosis while reducing mucin secretion, which are optimal properties for the management of rhinitis and associated conditions.

Pharm Pract (Granada) 2018; 16:1332. [PMID: 30416632 PMCID: PMC6207357 DOI: 10.18549/pharmpract.2018.03.1332] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2018] [Accepted: 09/20/2018] [Indexed: 12/14/2022] Open
Abstract
Background: Community pharmacists have a key role to play in the management of allergic rhinitis (AR). Their role is especially important because the majority of medications used to treat AR are available for purchase over-the-counter (OTC), allowing patients to self-select their own medications and bypass the pharmacists. Patients’ self-selection often results in suboptimal treatment selection, undertreated AR and poor clinical outcomes. In order for pharmacists to optimise the care for AR patients in the pharmacy, pharmacists need to be able to identify patient cohorts who self-select and are at high risk of mismanagement. Objectives: This study aimed to compare the demographics, clinical characteristics and medication selected, between pharmacy customers who choose to self-select and those who speak with a pharmacist when purchasing medication for their AR in a community pharmacy and identify factors associated with AR patients’ medication(s) self-selection behaviour. Methods: A cross-sectional observational study was conducted in a convenience sample of community pharmacies from the Sydney metropolitan area. Demographics, pattern of AR symptoms, their impact on quality of life (QOL) and medication(s) selected, were collected. Logistic regressions were used to identify factors associated with participants’ medication self-selection behaviour. Results: Of the 296 recruited participants, 202 were identified with AR; 67.8% were female, 54.5% were >40 years of age, 64.9% had a doctor’s diagnosis of AR, and 69.3% self-selected medication(s). Participants with AR who self-select were 4 times more likely to experience moderate-severe wheeze (OR 4.047, 95% CI 1.155-14.188) and almost 0.4 times less likely to experience an impact of AR symptoms on their QOL (OR 0.369, 95% CI 0.188-0.727). Conclusions: The factors associated with AR patients’ self-selecting medication(s) are the presence of wheeze and the absence of impact on their QOL due to AR symptoms. By identifying this cohort of patients, our study highlights an opportunity for pharmacists to engage these patients and encourage discussion about their AR and asthma management.

Abstract
INTRODUCTION A growing number of epidemiological studies suggest that paracetamol, which is commonly used in children, may be a risk factor for asthma, allergic rhinitis, and atopic eczema. OBJECTIVE The aim of this study was to determine and characterize the correlation between paracetamol use and asthma, allergic rhinitis, and atopic eczema symptoms in the Polish population. MATERIAL AND METHODS The study is part of the ECAP project involving the use of the ISAAC and ECRHS questionnaires. Completed questionnaires of 18,617 subjects, including 10,011 (53.8%) females, were analyzed. Children aged 6-7 (n=4,510), adolescents aged 13-14 (n=4,721), and adults aged 20-44 (n=9,386) constituted 24.2%, 25.4%, and 50.4% of respondents, respectively. Study subjects lived in 8 major urban centres and one rural area. The frequency of paracetamol use during the previous 12 months and symptoms of asthma, allergic rhinitis, and atopic eczema during that period were analyzed. RESULTS The use of paracetamol was associated with a significant dose-dependent increase in the risk of asthma symptoms in all evaluated age groups. This was demonstrated via odds ratios (OR) for developing asthma symptoms, including wheezing or whistling in the chest in 6-7-year-olds and exercise-induced shortness of breath in 13-14-year-olds and adults, depending on the frequency of paracetamol use in the previous 12 months, compared to no paracetamol intake during that period. CONCLUSIONS The use of paracetamol in the last 12 months was associated with a significant dose-dependent increase in the risk of rhinitis and skin allergy symptoms, as demonstrated by the odds ratio. Therefore, frequent paracetamol use may be a risk factor for symptoms of asthma, rhinitis, and skin allergy in the Polish population.

Abstract
Allergic rhinitis (AR) is impacted by allergens and air pollution but interactions between air pollution, sleep and allergic diseases are insufficiently understood. POLLAR (Impact of air POLLution on sleep, Asthma and Rhinitis) is a project of the European Institute of Innovation and Technology (EIT Health). It will use a freely-existing application for AR monitoring that has been tested in 23 countries (the Allergy Diary, iOS and Android, 17,000 users, TLR8). The Allergy Diary will be combined with a new tool allowing queries on allergen, pollen (TLR2), sleep quality and disorders (TRL2) as well as existing longitudinal and geolocalized pollution data. Machine learning will be used to assess the relationship between air pollution, sleep and AR comparing polluted and non-polluted areas in 6 EU countries. Data generated in 2018 will be confirmed in 2019 and extended by the individual prospective assessment of pollution (portable sensor, TLR7) in AR. Sleep apnea patients will be used as a demonstrator of sleep disorder that can be modulated in terms of symptoms and severity by air pollution and AR. The geographic information system GIS will map the results. Consequences on quality of life (EQ-5D), asthma, school, work and sleep will be monitored and disseminated towards the population. The impacts of POLLAR will be (1) to propose novel care pathways integrating pollution, sleep and patients' literacy, (2) to study sleep consequences of pollution and its impact on frequent chronic diseases, (3) to improve work productivity, (4) to propose the basis for a sentinel network at the EU level for pollution and allergy, (5) to assess the societal implications of the interaction.

Abstract
Nasal eosinophil examination is routine for the diagnosis of nasal eosinophil-positive rhinitis in patients with rhinorrhea symptoms. This retrospective data investigated whether testing for nasal discharge eosinophils is useful for diagnosing childhood allergic asthma, and changes of positive rates by each age. Infants and young children (n = 180) with at least 3 recurrent episodes at intervals of ≥ 1 week of respiratory symptoms and bronchodilator inhalation improvements, were divided into an asthma group and a non-asthma group, and the presence or absence of nasal discharge eosinophils was examined by age. Correlations between nasal discharge eosinophils and other predictive factors for persistent asthma were also examined. The evaluation of nasal discharge eosinophils in the asthma group showed a significantly high positive rate in older age groups than in the 0–1-year-old age group (p< 0.05–0.001). However, none of the asthma patient groups had any significant changes between the 0–1-year-old group and older groups. This pattern was similar for other risk factors, showing correlations between nasal discharge eosinophils and other predictive factors.

Abstract
Chronic rhinitis and rhinosinusitis are among the most common conditions worldwide with significant morbidity and decreased quality of life. Although the pathogenesis of these conditions is multifactorial, there has been increasing evidence for the role of environmental factors such as aeroallergens and air pollutants as initiating or exacerbating factors. This review will outline the current literature focusing on the role of aeroallergens and air pollution in the pathogenesis of chronic sinonasal inflammatory conditions.

Abstract
PURPOSE Middle turbinate head edema has recently been found to have high specificity for diagnosis of inhalant allergy. However, subtle mucosal edema can be difficult to appreciate under white light endoscopy. Narrow band imaging (NBI) has the potential to demonstrate edema by identifying reduced mucosal vascularity and improve sensitivity for the detection of mucosal edema. Narrow band imaging was assessed to determine its utility in objectifying mucosal edema. MEATERIALS AND METHODS A cross-sectional diagnostic study was performed on patients with edematous mucosa of the middle turbinate head. Under traditional white light endoscopy, areas of edematous mucosa were identified. Using NBI, these areas were compared to areas of normal mucosa on the middle turbinate head. NBI images of these same areas were then converted to grey scale and a vascularity index was created by pixel analysis and brightness in Fiji Image J software (Wisconsin, US). RESULTS Thirty-three middle turbinates were assessed (age 42.4 ± 12.5, 42.4% female). NBI discriminated between areas identified under white light endoscopy as edematous and normal (158.2 ± 48.4 v 96.9 ± 32.7 p < 0.01). Receiver operating curve (ROC) analysis suggested a threshold of 115 brightness units to define endoscopically visible edematous mucosa with sensitivity 70% and specificity 79% (ROC AUC, p = 0.85). CONCLUSIONS NBI can differentiate edematous from normal mucosa. The potential for an objective measure of mucosal edema may assist research efforts and may provide a more sensitive tool for subtle mucosal inflammatory changes.

Abstract
BACKGROUND Adherence to pharmacotherapy reduces symptoms of asthma and rhinitis, however, little is known of its impact on school performance. OBJECTIVE To evaluate the impact of pharmacotherapy in absenteeism and school performance in a child population. METHODS A cross-sectional study, carried out in eight schools. All participants and their parents were given a questionnaire assessing parameters related to respiratory diseases and pharmacotherapy. Data on school performance was obtained from the academic history of each child who participated in the study. Adherence to pharmacotherapy was classified as a correct use of therapy for more than five days per week. RESULTS 1109 children agreed to participate. Students were divided into two groups: symptomatic (36%) and asymptomatic (63%). The symptomatic group had a higher frequency of school absenteeism (1 vs. 3.1days/year/patient p<0.01) and lower academic performance (failed: 20% vs. 33% p<0.01). After dividing the symptomatic group between adherents and non-adherents to the pharmacotherapy, the group of adherents had a similar school performance to the asymptomatic group and it was significantly different from the no-adherent group. CONCLUSION Respiratory symptoms are associated with poor school performance and with an increase in school absenteeism, but adherence to pharmacotherapy can reduce these negative impacts in children.

Abstract
BACKGROUND The relationship between allergic disease and irritable bowel syndrome (IBS) is poorly understood. We aimed to investigate the potential association as well as the underlying immunological mechanisms. METHODS A retrospective case-control study of 108 atopic patients from among outpatients in an allergy clinic (allergic rhinitis [AR], n = 49; chronic urticaria [CU], n = 59) and 74 controls from among ward companions was conducted from November 2016 to March 2017. The detection rates and related gastrointestinal (GI) symptoms of IBS, as well as immunological indices, were calculated. RESULTS CU patients had a trend of increase in the detection of IBS compared to controls (OR = 4.846; 95% CI 0.967-24.279, p = 0.077). Loose stools (OR = 2.406; 95% CI 1.075-5.386, p < 0.05) and viscous stools (OR = 2.665; 95% CI 1.250-5.682, p < 0.05) were more common in CU patients. Atopic patients positive for serum total immunoglobulin E (IgE) (OR = 3.379; 95% CI 1.088-10.498, p < 0.05) or house dust mite (HDM)-specific IgE (OR = 3.640; 95% CI 1.228-10.790, p < 0.05) were more likely to have abdominal bloating. Besides, a positive association between levels of total IgE and severity of abdominal bloating was observed (p < 0.05). An HDM-specific IgE-positive reaction was independently associated with abdominal bloating in atopic patients (p < 0.05). CONCLUSIONS Allergic disease has a clear clinical association with IBS with more frequent and severe symptoms of IBS. CU patients have a tendency to suffer from IBS, usually with diarrhea. Serum total IgE and HDM-specific IgE are positively correlated with GI symptoms in atopic patients.

Abstract
Entamoeba histolytica produces, in axenic culture, the monocytes locomotion inhibitory factor (MLIF), a oligopeptide with selective anti-inflammatory properties. We evaluated the effect of MLIF on the expression of pro- and anti-inflammatory cytokines in CD4+ T lymphocytes from children with asthma and allergic rhinitis. Twelve children with severe asthma, 12 children with allergic rhinitis and 6 healthy controls were recruited for this study between May and December 2016. CD4+ T cells were cultured for 24 h at 37°C, 5% CO2 in the presence of MLIF, 1-phorbol 12-myristate 13-acetate (PMA), MLIF+PMA or RPMI. Interleukin-10 (IL-10), IL-4, interferon gamma (IFN-γ) and tumor necrosis factor alpha (TNF-α) expression levels were measured in the supernatants of T-cell cultures using the enzyme-linked immunosorbent assay (ELISA). Pro- and anti-inflammatory cytokines were inhibited by MLIF (IFN-γ p=0.0036, TNF-α p<0.001, IL-4 p=0.0082) in asthmatic patients, however IFN-γ was not significantly inhibited (NS) in patients with allergic rhinitis when compared to the RPMI group. In CD4+ T cells treated with PMA+MLIF, the expression levels of IFN-γ, TNF-α and IL-4 were strongly inhibited (p<0.001, p<0.001 and p<0.0094), compared to PMA treatment alone, for both, rhinitis and asthma. IL-10 expression was not affected by MLIF in neither of the two diseases. We conclude that MLIF alters the pro/anti-inflammatory balance and induces inhibition of IL-4, IFN-γ and TNF-α, but does not affect IL-10.

Abstract
A Golden Retriever cross was presented with a four week history of violent sneezing and licking at the nasal planum. Nasal mycosis was diagnosed and Aspergillus sp. presumed the causative agent, until culture, PCR and DNA sequencing showed that Scedosporium apiospermum, an uncommonly diagnosed, yet emerging, fungal pathogen, was the agent responsible. Debridement of the fungal plaques and systemic itraconazole therapy resulted in complete resolution of clinical disease. We discuss the current literature on S. apiospermum, review its clinical significance and question the validity of its ‘complex’ taxonomy.

Abstract
Introduction The use of saline irrigation for nasal washes is a well established procedure in the treatment of sinonasal inflammation and infection. In addition to saline solutions, Ringer's lactate is also an efficient option for nasal washes and humidification. Objective To assess the comfort, humidification and tolerance regarding stinging sensation, provided by sodium chloride nasal gel at the concentrations of 4.5 mg/g and 6.0 mg/g through questionnaires answered by the patients. Methods A total of 60 patients, 56 females, aged between 22 and 66 years old (mean age of 47) and 4 males, aged between 36 and 66 years (mean age of 49), were included in the study for a period of 17 days (±2 days) treatment. The patients were monitored by a general practitioner throughout the study period. They were instructed to apply each product in both nostrils twice a day during a 7-day period (±2 days). The patients were evaluated prior to the use of the first product at visit 0 (V0), after 7 days of treatment (±2 days) at visit 1 (V1), after 3 days of product discontinuation at visit 2 (V2) and after 7 days (±2 days) of treatment with the second product, in visit 3 (V3). Results A significant difference (5% significance) was observed regarding comfort and stinging sensation between the two different concentrations; comfort was higher and stinging was lower with the 6.0 mg/g concentration gel. No difference in humidification was observed between the two treatments. Conclusion Ringer's lactate at the concentration of 6.0 mg/g was superior to that at 4.5 mg/g for parameters comfort and stinging sensation. No statistical difference was observed between the two products regarding nasal humidification.

Abstract
Background Collecting data on the localization of users is a key issue for the MASK (Mobile Airways Sentinel networK: the Allergy Diary) App. Data anonymization is a method of sanitization for privacy. The European Commission's Article 29 Working Party stated that geolocation information is personal data.To assess geolocation using the MASK method and to compare two anonymization methods in the MASK database to find an optimal privacy method. Methods Geolocation was studied for all people who used the Allergy Diary App from December 2015 to November 2017 and who reported medical outcomes. Two different anonymization methods have been evaluated: Noise addition (randomization) and k-anonymity (generalization). Results Ninety-three thousand one hundred and sixteen days of VAS were collected from 8535 users and 54,500 (58.5%) were geolocalized, corresponding to 5428 users. Noise addition was found to be less accurate than k-anonymity using MASK data to protect the users' life privacy. Discussion k-anonymity is an acceptable method for the anonymization of MASK data and results can be used for other databases.

Abstract
BACKGROUND The respiratory epithelium is mainly constituted by caliciform (produces mucus, responsible of keeping moisture and trapping particles) and ciliated cells (transports mucus into the pharynx, by the movement of multiple cilia). For centuries, nasal lavages have been used for different rhinosinusal conditions. Some studies suggest not only a direct effect on the mobilisation of secretions, but also an improvement in mucociliary clearance rates. To our knowledge, the impact of temperature in nasal lavages has been scarcely studied. METHODOLOGY/PRINCIPAL We used the saccharin test-applying it in the inferior turbinate and timing the detection of its taste-, to estimate mucociliary clearance rates before and after nasal lavages with saline solution at room (20 °C) or body (37 °C) temperatures. RESULTS 78 healthy subjects were studied, with a mean saccharin test time of 13.88 min. Then, a nasal lavage was performed, half with 20 °C saline and the other with 37 °C. In both, times improved from baseline (from 13.66 to 11.59 and 14.06 to 9.4 min, respectively) with p values < 0.05. CONCLUSIONS Nasal lavages with saline solution improve mucociliary clearance as measured by saccharin test. Temperature seems to matter, which should be taken into account when indicating nasal lavages to our patients.

Segundo GRS, Canabrava LCMN. Sensitization to Aeroallergens in Patients with Primary Immunodeficiencies. Int Arch Allergy Immunol 2018; 177:255-258. [PMID: 30007976 DOI: 10.1159/000490673] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2018] [Accepted: 06/05/2018] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Primary immunodeficiencies (PID) are a heterogeneous group of diseases that cause alterations in the immune system, leading to the increased susceptibility to infections, autoimmune diseases, and malignancies. The aim was to evaluate the presence of clinical manifestations and diagnoses of asthma, rhinitis, and atopic dermatitis in patients diagnosed with PID, and correlate these with allergen sensitization verified by skin prick testing (SPT). MATERIAL AND METHODS This cross-sectional, descriptive, and observational study was conducted from February 2015 to February 2016. We performed a medical report analysis and SPT for aeroallergens in patients with a PID diagnosis. RESULTS Thirty-one patients with a PID diagnosis were included. The mean age of the participants was 15.41 years. From the 31 patients, 28 had symptoms suggestive of allergic disease (asthma, rhinitis, and atopic dermatitis) and only 7 presented positive SPT for at least 1 aeroallergen. CONCLUSION The frequency of allergenic sensitization in the group of patients with PID and symptoms suggestive of asthma, rhinitis, or atopic dermatitis is lower than that found in the general population, probably due the impairment of IgE formation secondary to their immunologic alterations.

Abstract
Objective: To observe the process of nasal mucosa injury and repair induced by nasal decongestants in guinea pigs Methods: Sixty-five male guinea pigs were randomly divided into 4groups by digital random method.The guinea pigs in Group A (20 guinea pigs)were treated with 2 sprays of 0.1% Naphazoline 6 times a day for 2 weeks; Group B (20 guinea pigs)with 2 drops of 1% Ephedrine 6 times a day for 2 weeks; Group C(20 guinea pigs) with 2 sprays of Naphazolin hydrochloride and Chlorphenamine Maleate Nasal Spray 8 times a day for 2 weeks.Group D (5guinea pigs)did not do any intervention as a control group.At the end of first and second weekend, 6 guinea pigs randomly selected from each group were observed the morphological changes of the nasal cavity with nasal endoscope and pathological microscope.Two weeks after stopping use of decongestant, 24 animals were grouped.Three guinea pigs were selected randomly from each group to form Group E (n=9) and Group F (n=9)respectively. The 6 remaining guinea pigs falled into Group G. Group E received 2 sprays of Mometasone Furoate Nasal Spray once a day for 2 weeks; Group F received 1 ml 2.3% saline to wash the nasal cavities once a day for 2 weeks.Group F was used to show the natural progess without any treatment.At the end of the third and fourth weekend, nasal endoscopic and pathological microscopes were used to observe the nasal cavity structure and the pathological changes of nasal mucosa. Results: Nasal mocusa congestion and edema were observed with nasal endoscopy after 2 weeks of using nasal decongestant. Cell edema, blood vessel expansion, acute and chronic inflammatory cell infiltration, cilium lodging or loss were observed under the pathological microscope in GroupA, B, C. After using MometasoneFuroate Nasal Spray and 2.3% saline for 2 weeks, the above changes were all recovered in Group E and F. No recovery was found in Group G. Conclusions: Short-term and over dose of nasal decongestant can result in the injury of nasal mucosa in guinea pigs, and the injury is much severe as using decongestant last longer.MometasoneFuroate nasal spray and 2.3% saline can repair the injury.

Abstract
Background Folk prescriptions continue to be important sources of childhood lead poisoning. Nasal spray folk prescriptions for treating rhinitis has only been reported once previously as a cause of lead poisoning. Case presentation We identified three pediatric cases of severe lead poisoning caused by nasal spray folk medicines prescribed for treating rhinitis. The three patients had similar clinical manifestations including: severe abdominal pain, headache, pale appearance and fatigue. Liver function tests were abnormal. Blood lead levels (BLLs) of the three patients were 91 μg/dL, 91 μg/dL, and 105 μg/dL, respectively. After chelation BLLs decreased. The lead content of the three folk remedies as measured by inductively coupled plasma mass spectrometry (ICP-MS) were 14.8, 22.3, and 33.4%. All the symptoms resolved during a course of chelation therapy. There were no severe side effects of treatment. Conclusions Nasal spray folk prescriptions for treating rhinitis may contain extremely high bio-accessible lead content and are potential sources of lead poisoning. Clinicians should be alert to this possibility especially in those children presenting with multisystem symptoms.

Serum periostin is associated with body mass index and allergic rhinitis in healthy and asthmatic subjects. Allergol Int 2018; 67:357-363. [PMID: 29223720 DOI: 10.1016/j.alit.2017.11.006] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2017] [Revised: 10/14/2017] [Accepted: 10/27/2017] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Many studies have attempted to clarify the factors associated with serum periostin levels in asthmatic patients. However, these results were based on studies of subjects mainly characterized by high eosinophil counts, which may present as an obstacle for clarification in the identification of other factors associated with serum periostin levels. The aim of this study was to determine the factors associated with serum periostin levels in healthy subjects. We also assessed some factors in asthmatic subjects to confirm their extrapolation for management of asthma. METHODS Serum periostin levels were measured in 230 healthy subjects. Clinical factors of interest included body mass index (BMI) and allergic rhinitis (AR). Additionally, we confirmed whether these factors were associated with serum periostin in 206 asthmatic subjects. We further evaluated several obesity-related parameters, such as abdominal fat distribution and adipocytokine levels. RESULTS Smoking status, blood eosinophil count, total immunoglobulin E, and the presence of AR were associated with serum periostin in healthy subjects. There was a negative association between BMI and serum periostin in both healthy and asthmatic subjects, while there was a tendency of a positive association with AR in asthmatic subjects. There were no differential associations observed for subcutaneous and abdominal fat in relation to serum periostin in asthmatic subjects. Serum periostin was significantly associated with serum levels of adiponectin, but not with leptin. CONCLUSIONS Our results provided clarity as to the factors associated with serum periostin levels, which could be helpful in the interpretation of serum periostin levels in clinical practice.

Abstract
BACKGROUND Precision medicine is an up-to-date strategy aimed at individualizing precise pathophysiological mechanisms. Thus, precision medicine is the basis for personalized medicine, inasmuch as it seeks to define the most appropriate treatment for each patient. Nasal cytology requires only an optical microscope, stains, glasses, and nasal cytology curettes. The procedure may last very few minutes using quick staining and, therefore, it can be considered a reliable point-of-care test in the office setting. METHODS Cross-sectional study that included 5030 outpatients with nasal disorders: 2612 males and 2418 females, with a mean age of 36.8 ± 17.1 years, who were attended to within a 5-year period. The patients were subdivided according to skin prick-test and nasal cytology results into subjects with allergic rhinitis or non-allergic rhinitis. Cellular forms were further subdivided based on their cytotype: NARNE (> 50% of neutrophils with absence of spores and bacteria); NARES (> 20% of eosinophils); NARMA (> 10% of mast cells); and NARESMA (> 20% of eosinophils and > 10% of mast cells). RESULTS 453 subjects (9%) had negative nasal cytology, 1056 (21%) had allergic rhinitis, 538 (10.7%) had NARES, 493 (9.8%) had nasal polyposis, 251 (5%) had rhinosinusitis, 221 (4.4%) had NARESMA 201 (4%) had infectious rhinitis, 131 (2.6%) had NARMA, 89 (1.8%) had NARNE, with the remaining subjects having a miscellaneous inflammatory/infectious profile. CONCLUSIONS Nasal cytology provides quick information about phenotype and endotype and can be repeated during follow-up to assess post-treatment changes.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a common disorder associated with other respiratory tract diseases such as asthma and inhalant allergy. However, the prevalence of these co-morbidities varies considerably in the existing medical literature and by phenotype of CRS studied. The study objective was to identify the prevalence of asthma, inhalant allergy and aspirin sensitivity in CRS patients referred to secondary care and establish any differences between CRS phenotypes. METHODS All participants were diagnosed in secondary care according to international guidelines and invited to complete a questionnaire including details of co-morbidities and allergies. Data were analysed for differences between controls and CRS participants and between phenotypes using chi-squared tests. RESULTS The final analysis included 1470 study participants: 221 controls, 553 CRS without nasal polyps (CRSsNPs), 651 CRS with nasal polyps (CRSwNPs) and 45 allergic fungal rhinosinusitis (AFRS). The prevalence of asthma was 9.95, 21.16, 46.9 and 73.3% respectively. The prevalence of self-reported confirmed inhalant allergy was 13.1, 20.3, 31.0 and 33.3% respectively; house dust mite allergy was significantly higher in CRSwNPs (16%) compared to CRSsNPs (9%, p < 0.001). The prevalence of self- reported aspirin sensitivity was 2.26, 3.25, 9.61 and 40% respectively. The odds ratio for aspirin sensitivity amongst those with AFRS was 28.8 (CIs 9.9, 83.8) p < 0.001. CONCLUSIONS The prevalence of asthma and allergy in CRS varies by phenoytype, with CRSwNPs and AFRS having a stronger association with both. Aspirin sensitivity has a highly significant association with AFRS. All of these comorbidities are significantly more prevalent than in non-CRS controls and strengthen the need for a more individualised approach to the combined airway.

Abstract
BACKGROUND Google Trends (GT) searches trends of specific queries in Google, which potentially reflect the real-life epidemiology of allergic rhinitis. We compared GT terms related to ragweed pollen allergy in American and European Union countries with a known ragweed pollen season. Our aim was to assess seasonality and the terms needed to perform the GT searches and to compare these during the spring and summer pollen seasons. METHODS We examined GT queries from January 1, 2011, to January 4, 2017. We included 15 countries with a known ragweed pollen season and used the standard 5-year GT graphs. We used the GT translation for all countries and the untranslated native terms for each country. RESULTS The results of "pollen," "ragweed," and "allergy" searches differed between countries, but "ragweed" was clearly identified in 12 of the 15 countries. There was considerable heterogeneity of findings when the GT translation was used. For Croatia, Hungary, Romania, Serbia, and Slovenia, the GT translation was inappropriate. The country patterns of "pollen," "hay fever," and "allergy" differed in 8 of the 11 countries with identified "ragweed" queries during the spring and the summer, indicating that the perception of tree and grass pollen allergy differs from that of ragweed pollen. CONCLUSIONS To investigate ragweed pollen allergy using GT, the term "ragweed" as a plant is required and the translation of "ragweed" in the native language needed.

Abstract
Airborne allergic diseases (allergic asthma, rhinitis and conjunctivitis) have reached epidemic proportions and are a great burden for both society and individuals. Therefore we need to better understand the physiopathological mechanisms and to increase clinical research in these diseases. However, traditional outpatient studies are difficult and have number of limitations, in particular the variability of allergen exposure. Yet allergen provocation tests, especially bronchial challenges in asthma, are excellent tools to measure the efficiency of anti-allergic therapies. Environmental exposure chambers (EEC) allow the performance of controlled allergen provocation tests on a large scale with remarkable sensitivity, specificity and reproducibility. Moreover, they allow a precise collection of allergic symptoms, making them interesting tools for patho-physiological and clinical studies. During the last thirty years, they have assisted the study of anti-allergic therapies and provided data on their pharmacodynamic characteristics, particularly in allergic rhinitis. However, there are still no EEC tests centered on asthma. The EEC of Strasbourg (ALYATEC®) was developed to fulfill two objectives: to allow standardized allergenic and non-allergenic exposures with better control of the parameters than in other EEC and to offer a place to study asthma and anti-asthmatic therapies safely.

Abstract
Background The global prevalence of allergic rhinitis, asthma, and atopic dermatitis has risen significantly over the last 2 decades. Allergic sensitization to aeroallergen is a major risk factor in developing the allergic disease. The prevalence of aeroallergen sensitization varies in different regions and countries. Objective To determine the prevalence of common aeroallergen sensitization and the atopic status among adult patients. Methods A cross-sectional, retrospective study. The data were collected from medical records and database of the result of skin prick test of patients who had the allergic symptoms or chronic urticaria in adult allergy clinic, Ramathibodi hospital from January 2004 to December 2015. Results A total of 1,516 of patients (female, 1,118 [73.7%]) were enrolled. The mean ages of participants were 41.34 (standard deviation, ±16.5) years. Fifty-eight percent (58%) of patients were diagnosed with allergic rhinitis, 19.7%, 3.2%, and 9.2% with asthma, atopic dermatitis, and chronic urticaria respectively. In the chronic urticaria group, 57.4% underwent the positive skin prick test to common aeroallergens. Mites were responsible for the most common inhaled allergen sensitization in this study as 50.1% of Dermatophagoides pteronyssinus, 32% of Dermatophagoides farinae, and 31.5% of house dust. Cockroach was the second most common aeroallergen sensitization as 32.3% followed by grass pollen, Bermuda (21.1%) and timothy (13.6%). The animal dander, cat and dog, occupied 12.9 and 10% respectively. Conclusion Mites were the most common cause of aeroallergen sensitization in all patients followed by cockroach, grass pollen, and animal dander. However, Bermuda sensitization has increased significantly in the last 6 years.

Abstract
BACKGROUND The burden of rhinitis is high. It is unknown to what extent this burden is related to inappropriate medication use. OBJECTIVE This study aimed to identify the way in which people with rhinitis medicate their condition and to evaluate the appropriateness of this medication management. METHODS Pharmacy customers who visited Sydney metropolitan community pharmacies and purchased medication for nasal symptoms were the sampling frame for this study. To determine the condition for which the participants were seeking medication and the appropriateness of their medication selection, the following data were collected with a researcher-administered questionnaire: participant's demographics, symptoms, medication selected. An expert panel of clinical researcher pharmacists and specialist respiratory physician evaluated the appropriateness of medication selection based on the Allergic Rhinitis and its Impact on Asthma international guidelines. RESULTS Two hundred and ninety-six participants were recruited from 8 pharmacies; 63.2% had a doctor's diagnosis for the symptoms for which they were selecting treatment. Seventy percent of participants self-selected their medications. Seventy-one percent of the participants were identified as having rhinitis. Overall, 16.5% of participants who had rhinitis selected optimal medications. Sixteen percent of participants with allergic rhinitis reported wheezing (6.3% selected optimal medications). CONCLUSIONS The majority of the participants with rhinitis selected suboptimal medications from community pharmacy highlighting the significant burden of rhinitis in community pharmacy and the contribution of medication management. Pharmacists need to take a proactive and evidence-based role in the management of rhinitis supported by clinical pathways when need to be articulated and promoted in all rhinitis guidelines.

Abstract
Purpose of Review Chronic rhinosinusitis is a disease with high prevalence, significant impact on health-related quality of life (HRQoL) and it is associated with substantial healthcare and productivity costs. We face an urgent need to improve the level of disease control and achieve higher patient satisfaction and disease prevention. Precision medicine is increasingly recognized as the way forward in optimal patient care. The combination of personalized care, prevention of disease, prediction of success of treatment, and participation of the patient in the elaboration of the treatment plan is expected to guarantee the best possible therapeutic approach for individuals suffering from a chronic disabling condition. Recent Findings This is a narrative review on the current state of endotypes, biomarkers, and targeted treatments in chronic inflammatory conditions of the nose and paranasal sinuses. Different phenotypes of rhinitis and chronic rhinosinusitis (CRS) have been described based on symptom severity and duration, atopy status, level of control, comorbidities, and presence or absence of nasal polyps in CRS. The underlying pathophysiological mechanisms are diverse, with different endotypes being recognized. Novel emerging therapies are targeting specific pathophysiological pathways or endotypes. This endotype-driven treatment approach requires careful selection of the patient population who might benefit from a specific treatment. Summary This review provides a comprehensive overview of the current state of endotypes, biomarkers and targeted treatments in chronic inflammatory conditions of the nose and paranasal sinuses.

Abstract
PURPOSE OF REVIEW Glutathione S-transferase (GST) genes are involved in oxidative stress management and may modify the impact of indoor air pollution. We aimed to assess the influence of GST genes on the relationship between indoor air pollution and allergy/lung function. RECENT FINDINGS Our systematic review identified 22 eligible studies, with 15 supporting a gene-environment interaction. Carriers of GSTM1/T1 null and GSTP1 val genotypes were more susceptible to indoor air pollution exposures, having a higher risk of asthma and lung function deficits. However, findings differed in terms of risk alleles and specific exposures. High-exposure heterogeneity precluded meta-analysis. We found evidence that respiratory effects of indoor air pollution depend on the individual's GST profile. This may help explain the inconsistent associations found when gene-environment interactions are not considered. Future studies should aim to improve the accuracy of pollution assessment and investigate this finding in different populations.

Abstract
Background 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. Methods In 2016, a postal survey was conducted among a random population sample of 8000 adults in Helsinki, Finland with a 50.5% response rate. Results 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. Conclusions 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).

Abstract
Mould spores constitute the largest portion of biologic particulate matter suspended in the outdoor atmosphere. There is no universal method for collecting airborne mould spores. The most used sampler, Hirst's apparatus, operates continuously and gives results in individual spores per cubic metre of air. Spore concentrations depend on available substrates, human activities such as agriculture, season, diurnal meteorological variations and climate changes. Under natural conditions, concentrations of over 100,000 spores per cubic metre are not exceptional. Cladosporium is the most commonly identified outdoor mould. The association between respiratory health and outdoor mould spore exposure has been assessed in clinical studies, and also by cross-sectional, and less often longitudinal, epidemiological studies. The relationship between asthma exacerbations and specific mould spores has been demonstrated in longitudinal studies. Cross sectional studies have related measurements of mould spore concentrations to severity of bronchial symptoms, drug consumption and peak-flow measurements in groups of asthmatic subjects. Ecological time-series studies use daily indicators of asthma exacerbations (emergency room visits, hospitalizations) within the general population. The moulds mainly incriminated are Cladosporium and Alternaria. They are associated with seasonal, but also perennial, asthma and rhinitis. Further studies are needed to better assess the impact of outdoor moulds on health, particularly basidiomycetes. Studies with molecular biology tools are probably a way forward.

Abstract
The sinonasal tract plays important roles in respiration, olfaction, and defense against external pathogens. Like many organ systems, the nose and sinuses undergo several changes with advancing age that can play a role in the development of disease. This article discusses the physiology of the aging sinonasal tract and reviews the common diseases affecting older patients, such as rhinitis and rhinosinusitis.

Abstract
The nose forms the first 8 cm of the upper respiratory tract and is responsible for cleansing, humidification, and temperature control of the supplied air. This is also referred to as conditioning. The nasal valve region, formed by the head of the lower nasal concha, portions of the cartilaginous septum, and the upper lateral cartilage, is responsible for diffusing and accelerating the respiratory airflow. Prerequisite are regular mucociliary clearance and sufficient air passage. Hypertrophy of the lower nasal turbinate is one of the most common causes of symptomatic nasal congestion. In unclear cases, rhinometric procedures are available. In addition to conservative therapy of allergic or vasomotor rhinitis by specific immunotherapy or topical corticoids, numerous interventional procedures are available to reduce conchal tissue. All modern methods have a high degree of protection of the respiratory mucosa in common.

Establishment of the nasal microbiota in the first 18 months of life: Correlation with early-onset rhinitis and wheezing. J Allergy Clin Immunol 2018; 142:86-95. [PMID: 29452199 DOI: 10.1016/j.jaci.2018.01.032] [Citation(s) in RCA: 56] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2017] [Revised: 12/19/2017] [Accepted: 01/24/2018] [Indexed: 12/18/2022]
Abstract
BACKGROUND Dynamic establishment of the nasal microbiota in early life influences local mucosal immune responses and susceptibility to childhood respiratory disorders. OBJECTIVE The aim of this case-control study was to monitor, evaluate, and compare development of the nasal microbiota of infants with rhinitis and wheeze in the first 18 months of life with those of healthy control subjects. METHODS Anterior nasal swabs of 122 subjects belonging to the Growing Up in Singapore Towards Healthy Outcomes (GUSTO) birth cohort were collected longitudinally over 7 time points in the first 18 months of life. Nasal microbiota signatures were analyzed by using 16S rRNA multiplexed pair-end sequencing from 3 clinical groups: (1) patients with rhinitis alone (n = 28), (2) patients with rhinitis with concomitant wheeze (n = 34), and (3) healthy control subjects (n = 60). RESULTS Maturation of the nasal microbiome followed distinctive patterns in infants from both rhinitis groups compared with control subjects. Bacterial diversity increased over the period of 18 months of life in control infants, whereas infants with rhinitis showed a decreasing trend (P < .05). An increase in abundance of the Oxalobacteraceae family (Proteobacteria phylum) and Aerococcaceae family (Firmicutes phylum) was associated with rhinitis and concomitant wheeze (adjusted P < .01), whereas the Corynebacteriaceae family (Actinobacteria phylum) and early colonization with the Staphylococcaceae family (Firmicutes phylum; 3 weeks until 9 months) were associated with control subjects (adjusted P < .05). The only difference between the rhinitis and control groups was a reduced abundance of the Corynebacteriaceae family (adjusted P < .05). Determinants of nasal microbiota succession included sex, mode of delivery, presence of siblings, and infant care attendance. CONCLUSION Our results support the hypothesis that the nasal microbiome is involved in development of early-onset rhinitis and wheeze in infants.

Abstract
Background Globally, rhinitis is one of the most common chronic disorders. Despite availability of drugs to manage the symptomatology of rhinitis, researchers still focus on identification of novel molecular targets for better management. MicroRNAs are implicated in many biological and pathological processes. However, the role of miR-17-5p in rhinitis remains unexplored. This study aimed to explore the role of miR-17-5p in lipopolysaccharide (LPS)-induced injury of nasal epithelial RPMI2650 cells and to elucidate the possible underlying molecular mechanism. Results LPS damaged RPMI2650 cells by inhibiting cell proliferation, promoting apoptosis, and stimulating the release of inflammatory cytokines. miR-17-5p expression was significantly increased in RPMI2650 cells following treatment with LPS. Furthermore, it was found that overexpression of miR-17-5p led to aggravation of LPS-induced injury. miR-17-5p negatively regulated expression of Smad7; overexpression of Smad7 protected the RPMI2650 cells by inactivating NF-κB and Wnt/β catenin pathways and vice versa. Conclusions Overexpression of miR-17-5p aggravated LPS-induced damage of RPMI2650 cells. Expression of Smad7 was negatively regulated by miR-17-5p; Smad7 expression inactivated NF-κB and Wnt/β catenin pathways.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2018; 6:1580-1587.e2. [PMID: 29361510 DOI: 10.1016/j.jaip.2017.11.032] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/16/2017] [Revised: 11/02/2017] [Accepted: 11/20/2017] [Indexed: 02/08/2023]
Abstract
BACKGROUND Allergic diseases are increasing in sub-Saharan Africa, but few studies have characterized the burden among adults. OBJECTIVE We conducted a study to evaluate the prevalence and risk factors of allergic disorders in urban and rural Uganda. METHODS We present a cross-sectional analysis of enrollment data from a population-based cohort study of adults aged ≥35 years in urban and rural Uganda. Sociodemographic and both lifetime and 12-month respiratory symptoms data were collected and spirometry was conducted following standard guidelines. RESULTS In 1,308 adults (median age 43.8 years and 52.3% female), we found an age-adjusted prevalence of 6.8% for asthma (9.8% urban, 4.3% rural; P < .001), 11.9% for allergic rhinitis (16.4% urban, 7.8% rural; P < .001), and 8.2% for eczema (9.9% urban, 7.8% rural; P = .15). Urbanization was the primary driver of asthma, accounting for 61.4% of cases (95% confidence interval [CI] 22.0% to 83.4%), and was the strongest risk factor for any allergic illness (odds ratio [OR] = 1.87, 95% CI 1.39-2.51). Parental asthma was not associated with allergic illness. Asthma was associated with a lower forced expiratory volume in 1 second (FEV1) by 0.56 z scores (95% CI 0.33-0.80). We found a dose-response association between lower quintiles of the FEV1/forced vital capacity ratio and both hospitalization (OR = 1.77, 95% CI 1.21-2.59) and impairment in daily activities (1.65, 1.20-2.27). CONCLUSIONS Asthma and allergic rhinitis were twice as prevalent in urban settings. Asthma was associated with greater impairment and worse lung function outcomes. We identified a high prevalence of allergic disorders in Uganda, which can be expected to increase due to urbanization and resultant exposures throughout early development.
