Severity of allergic rhinitis impacts sleep and anxiety: results from a large Spanish cohort

Circulating interleukin-27 is associated with the risk of chronic periodontitis and allergic rhinitis: A Mendelian randomization analysis

BACKGROUND

Chronic periodontitis (CP) and allergic rhinitis (AR) have attracted wide attention as global public health problems with high incidence. Recent studies have shown that circulating interleukin-27 (IL-27) is associated with the risk of CP and AR. The aim of this study is to analyze the causal effect between them using Mendelian randomization (MR).

METHODS

Bidirectional MR analyses were performed with the use of publicly available genome-wide association study (GWAS) data. Summary data on circulating IL-27, CP, and AR published in genome-wide association studies were collected. Instrumental variables (IV) were extracted using assumptions of correlation, independence and exclusivity as criteria. Inverse variance weighting (IVW) was used as the main method, combined with weighted median method (WM) and MR-Egger and other MR Analysis methods for causal inference of exposure and outcome. Cochran's Q and MR-Egger intercept were used for sensitivity analysis.

RESULTS

The IVW study showed a causal effect between increased circulating IL-27 levels and increased risk of CP (OR = 1.14, 95%CI = 1.02-1.26, p = .020). Similarly, the increase of circulating IL-27 level had a causal effect on the decreased risk of AR (OR = 0.88, 95%CI = 0.80-0.97, p = .012). In addition, IVW study found that there was a causal between the increased risk of CP and circulating IL-27 level (OR = 1.05, 95%CI = 1.01-1.10, p = .016). However, there was no significant causal relationship between the risk of AR and circulating IL-27 levels (OR = 0.97, 95%CI = 0.91-1.02, p = .209). no significant heterogeneity or horizontal pleiotropy was found in sensitivity analysis.

CONCLUSIONS

There is a causal effect between circulating IL-27 level and CP, AR, which will help to find new ideas and methods for the diagnosis and treatment of CP and AR.

A meta-analysis of the prevalence and risk of mental health problems in allergic rhinitis patients

OBJECTIVE

Allergic rhinitis (AR), a prevalent global health concern, is increasingly recognized for its impact beyond physical symptoms, affecting mental health. This research examined the extent of AR's psychological burden and sleep disturbances.

METHODS

A systematic search of four databases yielded 49 studies reporting mental health problems in 18,269,265 individuals (15,151,322 AR patients and 3,117,943 controls). The primary outcomes included all mental health problems in AR patients. Subgroup analyses based on outcome and AR severity, country, AR diagnosis, recruitment setting, and age were performed. Secondary outcomes included the risk of these problems compared to controls (healthy or without AR).

RESULTS

In AR, depression (25%), anxiety (25%), stress (65%), distress (57%), suicidal thoughts (14%) and attempts (4%), poor sleep quality (48%), insomnia (36%), sleep impairment (33%), and insufficient sleep duration <7 h (59%) were prevalent. The severity of these outcomes differed significantly. Patients' country, AR diagnostic method, recruitment method/setting, and age group were significant effect modifiers. Compared to controls, AR resulted in significantly higher risk of depression, anxiety, stress, suicidal attempts and thoughts, insomnia, and sleep impairment.

CONCLUSION

AR patients had significantly lower sleep duration. Mental health problems are very common among AR patients, further exacerbating their sleep quality and duration and intention to suicide.

Association between allergic diseases, generalized anxiety disorder, and depressive symptoms in South Korean adolescents: a secondary data analysis of the 2022 Korea Youth Risk Behavior Survey

PURPOSE

This study investigated the relationship between allergic diseases, general anxiety disorder, and depressive symptoms among Korean adolescents.

METHODS

A secondary analysis was conducted on the findings of the 18th Korea Youth Risk Behavior Survey (2022). The study included 51,850 adolescents and analyzed the relationships among allergic diseases, general anxiety disorder, and depressive symptoms using complex samples logistic regression analysis.

RESULTS

Among the Korean adolescents, 12.7% experienced general anxiety disorder, while 28.7% experienced depressive symptoms. The prevalence of allergic diseases was 5.7% for asthma, 36.3% for allergic rhinitis, and 22.2% for atopic dermatitis. General anxiety disorder was associated with asthma and allergic rhinitis but not atopic dermatitis. Depressive symptoms were associated asthma, allergic rhinitis, and atopic dermatitis.

CONCLUSION

Examining the correlation among allergic diseases, general anxiety disorder, and depressive symptoms in adolescents underscores the need for implementing suitable strategies. Moreover, when addressing general anxiety disorder and depressive symptoms in adolescents, it becomes crucial to consider the presence of allergic diseases.

TET2 deficiency promotes anxiety and depression-like behaviors by activating NLRP3/IL-1β pathway in microglia of allergic rhinitis mice

BACKGROUND

Anxiety and depression-like behaviors in allergic rhinitis (AR) are attracting attention, while the precise mechanism has not been clearly elucidated. Recent evidence shows that neuroinflammation in anterior cingulate cortex (ACC) may be the core of these neuropsychiatric symptoms in AR. Here, we investigated the molecular link between the anxiety and depression-like behaviors and neuroinflammation in ACC.

METHODS

Mice were sensitized and challenged with ovalbumin (OVA) to induce AR. Nasal inflammation levels were assessed by H&E staining and PAS staining. Anxiety and depression-like behaviors were evaluated by behavioral experiments including open field test, forced swimming test, and sucrose preference test. Neuronal impairment was characterized via Nissl staining and 18FDG-PET. The role of ten-eleven translocation 2 (TET2) in AR-related anxiety and depression was assessed by Tet2-/- mice. In addition, the murine BV2 microglial cell line was utilized to explore the molecular mechanisms by which TET2 mediates neuroinflammation. The levels of TET2, NLRP3 and their downstream molecules were detected by immunohistochemistry, Western blot, Dot blot and ELISA. The effects of metformin on depression-like behaviors in AR mice were also evaluated.

RESULTS

AR mice showed significant anxiety and depression-like behaviors, which associated with the activation of ACC. Loss of TET2 activated the NLRP3/IL-1β pathway of microglia in AR mice, further accelerating the anxiety and depression-like behaviors. In addition, knockdown of TET2 activated the NLRP3/IL-1β pathway in BV2 cells. Metformin improved the neuropsychiatric symptoms of AR mice by reducing the activation of NLRP3/IL-1β pathway after upregulating TET2.

CONCLUSION

TET2 deficiency activates the NLRP3/IL-1β pathway of microglia in the ACC, promoting the pathological process of anxiety and depression-like behavior in AR. Metformin could be effective in treating neuroinflammation by regulating microglia via TET2 up-regulation, indicating that metformin is a potential way to treat anxiety and depression-like behaviors in AR.

Effect of mesenchymal stem cell therapy in animal models of allergic rhinitis: A systematic review and meta-analysis

BACKGROUND

Allergic rhinitis (AR) is a worldwide problem that affects people of all ages, impairing patients' physical and mental health and causing great social expenditure. Animal studies have suggested the potential efficacy of mesenchymal stem cell (MSC) therapy in treating AR. Our meta-analysis was performed to evaluate the effect of MSC therapy in animal models of AR by pooling animal studies.

METHODS

The search was executed in PubMed, Embase, Web of Science, OVID, and the Cochrane Library for relevant studies up to February 2023. The applicable data were extracted from the eligible studies, and the risk of bias was assessed for each study. The meta-analysis was conducted using Review Manager (version 5.4.1) and Stata (version 15.1).

RESULTS

A total of 12 studies were included in the final analysis. Compared to the model control group, the MSC therapy group presented lower frequency of sneezing [(Standardized mean difference (SMD) -1.87, 95% CI -2.30 to -1.43)], nasal scratching (SMD -1.41, 95% CI -1.83 to -0.99), and overall nasal symptoms (SMD -1.88, 95% CI -3.22 to -0.54). There were also remarkable reductions after transplantation with MSCs in the levels of total immunoglobulin E (IgE) (SMD -1.25, 95% CI -1.72 to -0.79), allergen-specific IgE (SMD -1.79, 95% CI -2.25 to -1.32), and allergen-specific immunoglobulin G1 (SMD -1.29, 95% CI -2.03) in serum, as well as the count of eosinophils (EOS) in nasal mucosa (SMD -3.48, 95% CI -4.48 to -2.49). In terms of cytokines, MSC therapy significantly decreased both protein and mRNA levels of T helper cell 2 (Th2)-related cytokines, including interleukin (IL)-4, IL-5, IL-10, and IL-13.

CONCLUSION

MSC therapy has the potential to be an effective clinical treatment for AR patients by attenuating Th2 immune responses, reducing secretion of IgE and nasal infiltration of EOS, and consequently alleviating nasal symptoms.

The Relationship between Allergic Disease and Sexual Dysfunction: A Scoping Review

INTRODUCTION

Sexual dysfunction (SD) and allergic disease are common health concerns worldwide and bear a potential relationship. This scoping review is conducted to analyze the currently available data regarding the associations between these two health issues.

METHODS

A comprehensive literature search was performed in the databases of PubMed, MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science to retrieve studies that were published before January 2023. A narrative synthesis was conducted to analyze the effects of allergic diseases on SD based on the evaluation of the Female Sexual Function Index (FSFI) and International Index of Erectile Function (IIEF).

RESULTS

Twelve observational studies were included after the selection process. The results generally suggested lower FSFI or IIEF scores in patients with asthma, allergic rhinitis, allergic rhinoconjunctivitis, and urticaria compared to the healthy control groups. The underlying factors of this relationship could be inflammation, psychological factors, hormonal changes, sleep disorders, sexual behavior-related allergic reactions, social economic status, and the use of medications.

CONCLUSION

SD and allergic disease are interrelated based on the extant literature. This scoping review provides insights into the clinical implications of both entities, while more research studies are warranted to further elucidate this complex relationship.

Exploring the latest understanding on the role of immune mediators, genetic and environmental factors in pathogenesis of allergic rhinitis: a systematic review

Introduction

Despite well-defined clinical phenotypes of chronic rhinitis, the underlying in-depth pathophysiological mechanism, particularly with reference to the involvement of immune mediators, genetic, and environmental factors, are still not fully understood. Therefore, our aim was to give updated information on the pathogenesis of allergic rhinitis (AR), with an emphasis on the role of cytokines in adults aged 18 years and above. Additionally, we investigated the impact of genetic and environmental factors in the pathogenesis of AR.

Results

A search in various databases identified 1,178 records, and 18 studies were ultimately selected from January 2018 to April 2023. The total sample size in our studies was 4,317, with 2,186 in the experimental and 2,131 in control groups, respectively. The mean age was 33.4 years, with 43% were male, while 57% were female. According to the selected studies, various factors, including immune mediators, particularly cytokines, genetic, and environmental factors, were identified in the development of AR.

Conclusion

The selected studies presented findings on different factors and sub-factors in the pathogenesis of AR, making it a challenge for us to compare their results. However, based on our findings, researchers can link our identified factors to potential therapies for AR.

Anxiety in adults with asthma during the coronavirus disease 2019 pandemic: a Canadian perspective

BACKGROUND

Asthma is a chronic airway inflammatory disease that affects millions of Canadians and often contributes to higher levels of anxiety among patients. Since the coronavirus disease 2019 (COVID-19) pandemic was a time of increased anxiety and fear among the Canadian population, it was thought that those with asthma may experience heightened anxiety levels due to uncertain access to care, the potential to misinterpret asthma symptoms for symptoms of COVID-19 (or vice versa), and the concern about being treated differently by those around them when experiencing asthma symptoms. Therefore, this study sought to perform a cross-sectional analysis of the asthma-anxiety relationship in adults with and without asthma in the unique context of the COVID-19 pandemic from a Canadian perspective.

METHODS

This study employed the COVID-19 Associated Anxiety in Allergic Rhinitis and Asthma patients Experiencing Symptoms (CAAARES) survey, consisting of COVID-19-specific questions, the Generalized Anxiety Disorder Assessment-7 (GAD-7) and the Asthma Control Questionnaire-6 (ACQ-6). Data collection occurred through the Qualtrics XM platform and data analyses were conducted with the IBM SPSS Statistics 28 software.

RESULTS

A total of 741 valid responses were collected (asthma group, n = 244; control group, n = 497). 31.6% and 26.2% of respondents in the asthma and control groups, respectively, met the diagnostic criteria for GAD. There was no significant difference (p = .067) in mean GAD-7 scores between the two groups. A Hierarchal Multiple Regression (HMR) model was developed, and neither asthma status nor ACQ-6 score had a significant predictive effect on the GAD-7 score. There was a statistically significant (p < .001) weak positive correlation (r = .22) between GAD-7 and ACQ-6 scores. In a simple mediation (SMM) model, perceived COVID-19 stress of others was not identified as a significant mediator of the relationship between ACQ-6 and GAD-7 (indirect effect β = 0.014).

CONCLUSION

Our study of a Canadian cohort demonstrates elevated levels of anxiety overall, amongst both asthma and control groups. While AR status was significantly greater in the asthma group, it was not a significant predictive variable of GAD-7 score. Our data suggests that COVID-19-specific factors appear to have a greater contribution to anxiety than asthma status or control.

Comparing Lateral Rhytidectomy With and Without Neck Suture Suspension

Background: Characteristic aesthetic changes of the aging neck include skin laxity and rhytid formation, submental fat deposition, plastysmal banding, and ptosis of underlying structures that lead to the development of an obtuse cervicomental angle (CMA). Cervical rejuvenation techniques that aim to restore the CMA are widely discussed in the literature, and share variable outcomes. The aim of this study is to compare the restoration of the CMA in patients undergoing the addition of midline platysmal plication using a modified Giampapa stitch with absorbable PDS suture, to those patients undergoing standard deep plane lateral rhytidectomy alone. Methods: A retrospective cohort study was performed by a single surgeon in a private facial plastics practice. 264 patients undergoing rhytidectomy were included in the study. Pre and postoperative measurement differences in CMA degree and depth were compared in patients undergoing only traditional deep plane lateral rhytidectomy (TDPLR) in isolation, with those who also had modified suture suspension and platysma plication (MSSPP). The primary outcome in the study was the change in the degree of the CMA taken from standardized preoperative and postoperative surgical photos in the Frankfort profile view. Secondary outcomes include the change in the depth of the CMA as determined by the hyomental distance between study and control groups. Results: A total of 264 patients were identified who met the study criteria. A total of 134 (123 female; 11 male; average age, 62.66 ± 8.19) underwent TDPLR with MSSPP, and 130 (127 female; 3 male; average age, 63.09 ± 7.75) underwent TDPLR alone. All patients in the study underwent preoperative photographic evaluation in Frankfurt profile view and the same postoperative photographic evaluation at an average of 436.56 days (14.4 months) after surgery. Patients in the cohort study group were found to have a statistically significant increase in the depth of the CMA by an average of 13.9 degrees ± 6.26 and increase in the hyomental distance of 1.38 cm ± 0.87, compared to the control group who underwent traditional lateral rhytidectomy with an average CMA change of 6.87 degrees ± 6.7 (P = .00146) and hyomental distance increase of 0.75 ± 0.68 (P = .00031), respectively. Statistical significance was taken at P < .05. Conclusions: The results from this study indicate that the addition of a relatively minimally invasive approach to neck rejuvenation using a modified Giampapa stitch with absorbable PDS suture is helpful in restoring the CMA in an aging neck.

Cutoff Values of MASK-air Patient-Reported Outcome Measures

BACKGROUND

In clinical and epidemiological studies, cutoffs of patient-reported outcome measures can be used to classify patients into groups of statistical and clinical relevance. However, visual analog scale (VAS) cutoffs in MASK-air have not been tested.

OBJECTIVE

To calculate cutoffs for VAS global, nasal, ocular, and asthma symptoms.

METHODS

In a cross-sectional study design of all MASK-air participants, we compared (1) approaches based on the percentiles (tertiles or quartiles) of VAS distributions and (2) data-driven approaches based on clusters of data from 2 comparators (VAS work and VAS sleep). We then performed sensitivity analyses for individual countries and for VAS levels corresponding to full allergy control. Finally, we tested the different approaches using MASK-air real-world cross-sectional and longitudinal data to assess the most relevant cutoffs.

RESULTS

We assessed 395,223 days from 23,201 MASK-air users with self-reported allergic rhinitis. The percentile-oriented approach resulted in lower cutoff values than the data-driven approach. We obtained consistent results in the data-driven approach. Following the latter, the proposed cutoff differentiating "controlled" and "partly-controlled" patients was similar to the cutoff value that had been arbitrarily used (20/100). However, a lower cutoff was obtained to differentiate between "partly-controlled" and "uncontrolled" patients (35 vs the arbitrarily-used value of 50/100).

CONCLUSIONS

Using a data-driven approach, we were able to define cutoff values for MASK-air VASs on allergy and asthma symptoms. This may allow for a better classification of patients with rhinitis and asthma according to different levels of control, supporting improved disease management.

Management of allergic rhinitis symptoms in the pharmacy Pocket guide 2022

Background

Allergic rhinitis (AR) management requires a coordinated effort from healthcare providers and patients. Pharmacists are key members of these integrated care pathways resolving medication-related problems, optimizing regimens, improving adherence and recommending therapies while establishing liaisons between patients and physicians.

Methods

Allergic Rhinitis and its Impact on Asthma (ARIA) first published a reference document on the pharmacist's role in allergic rhinitis management in 2004. Several guidelines were developed over the past 20 years improving the care of allergic rhinitis patients through an evidence-based, integrated care approach.

Results

This ARIA/EAACI/FIP Position Paper is based on the latest ARIA in the Pharmacy guidelines and provides: (a) a structured approach to pharmacists identifying people with AR and/or allergic conjunctivitis as well as those at risk of poor disease control; (b) an evidence-based clinical decision support tool for optimising the management of allergic rhinitis in the community pharmacy; and (c) a framework of referral to the physician.

Conclusion

This document is not intended to be a mandatory standard of care but is provided as a basis for pharmacists and their staff to develop relevant local standards of care for their patients, within their local practice environment. Pharmacy care varies between countries, and the guide should be adapted to the local situation.

General Stress Among Young Adults with Asthma During the COVID-19 Pandemic

Background

The coronavirus disease 2019 (COVID-19) pandemic has profoundly affected the lives of the global population.

Objective

To explore anxiety and stress in relation to COVID-19 among young adults, and the potential influence of asthma and allergic rhinitis.

Methods

This cross-sectional study included 1644 participants from the population-based birth cohort BAMSE (Swedish abbreviation for Children, Allergy, Milieu, Stockholm, Epidemiology), participating in a follow-up at age 24 years and a COVID-19 follow-up conducted in August-November 2020 (mean age, 25.3 years). Anxiety and concern related to COVID-19 were analyzed as general anxiety, concern of own health and health of family members, and contact with online health care providers due to concern about COVID-19. Stress was measured with the perceived stress scale.

Results

Around half the participants reported increased anxiety due to COVID-19, and this was more common among females (57.0%, compared with 42.6% in males; P < .001). Young adults with asthma reported more concern about their own health (adjusted odds ratio, 1.50; 95% CI, 1.12-2.02) and perceived stress (adjusted regression coefficient [adjusted β], 1.49; 95% CI, 0.52-2.45) compared with peers without asthma, and this was more pronounced among females and those with uncontrolled asthma. Symptoms of allergic rhinitis were not associated with increased concern or anxiety in relation to COVID-19.

Conclusions

Young adults with asthma experience more COVID-19–related health concerns, compared with those without asthma, especially females and participants with uncontrolled asthma This needs to be considered in the care of young people with asthma.

Allergic rhinitis improvement after septorhinoplasty in a sample of allergic rhinitis patients with septal deviation: a quasi-experimental study

BACKGROUND

Allergic rhinitis (AR) is a chronic inflammatory disease that affects almost 30% of the adult population.

OBJECTIVE

To describe and compare the evolution of symptoms in patients diagnosed with AR and septal deviation prior to and following septoplasty (STP).

DESIGN AND SETTING

Quasi-experimental study developed in A Coruña University Hospital.

METHODS

Patients aged 18-65 years who had been diagnosed with AR and septal deviation were recruited. Obstruction airflow was evaluated before and after surgery, by means of anterior rhinomanometry (RNM). Severity symptoms and quality of life were assessed using a visual analogue scale (VAS) and the ESPRINT questionnaire, respectively.

RESULTS

A total of 50 subjects underwent STP and 42 were included in this study. Their mean age at the time of surgery was 34.16 ± 9.74 years (range 18-64). Significant reductions in mean VAS and ESPRINT were observed after surgery (P < 0.01). These outcomes were considered to represent an overall improvement in quality of life. The RNM results also improved significantly, from mean values of 478.07 ± 165.4 cm3/s before STP to 826.4 ± 175.5 cm3/s afterwards (P < 0.01).

CONCLUSIONS

The negative correlations of VAS and ESPRINT with RNM, from before and to after STP, demonstrate the efficacy of scales and questionnaires as objective methods for determining obstruction in the absence of rhinomanometry. Patients with allergic rhinitis and septal deviation showed improvements in obstruction severity and medication use after STP.

Sleep, Fatigue, and Depressive Symptoms among Female Nurses with Allergic Rhinitis

Allergic rhinitis (AR) is a common chronic disease that negatively affects physical and mental health. The purpose of this study was to determine the effects of allergic rhinitis on sleep, fatigue, and depressive symptoms among Korean female nurses. This was a cross-sectional study conducted using data from the Korea Nurses' Health Study (KNHS), and a total of 8645 female nurses was selected for the final analysis. The demographic characteristics, Body Mass Index, alcohol consumption, shift work, comorbidities (atopic dermatitis and asthma), self-rated health, sleep disturbance (Jenkins Sleep Questionnaire), fatigue (Chalder Fatigue Scale), and depressive symptoms (Perceived Health Questionnaire-9) were collected. The data were analyzed using chi-square tests, t-tests, and hierarchical multiple regression analyses. Participants with allergic rhinitis had significantly greater sleep disturbance, fatigue, and depressive symptoms than those without allergic rhinitis, and allergic rhinitis was a significant factor influencing sleep disturbance and fatigue among the participants after controlling for confounding variables. Therefore, it is imperative to develop effective interventions to manage allergic rhinitis symptoms and improve sleep and fatigue in affected nurses.

Validity, reliability, and responsiveness of daily monitoring visual analog scales in MASK-air®

Background

MASK-air® is an app that supports allergic rhinitis patients in disease control. Users register daily allergy symptoms and their impact on activities using visual analog scales (VASs). We aimed to assess the concurrent validity, reliability, and responsiveness of these daily VASs.

Methods

Daily monitoring VAS data were assessed in MASK-air® users with allergic rhinitis. Concurrent validity was assessed by correlating daily VAS values with those of the EuroQol-5 Dimensions (EQ-5D) VAS, the Control of Allergic Rhinitis and Asthma Test (CARAT) score, and the Work Productivity and Activity Impairment Allergic Specific (WPAI-AS) Questionnaire (work and activity impairment scores). Intra-rater reliability was assessed in users providing multiple daily VASs within the same day. Test-retest reliability was tested in clinically stable users, as defined by the EQ-5D VAS, CARAT, or "VAS Work" (i.e., VAS assessing the impact of allergy on work). Responsiveness was determined in users with two consecutive measurements of EQ-5D-VAS or "VAS Work" indicating clinical change.

Results

A total of 17,780 MASK-air® users, with 317,176 VAS days, were assessed. Concurrent validity was moderate-high (Spearman correlation coefficient range: 0.437-0.716). Intra-rater reliability intraclass correlation coefficients (ICCs) ranged between 0.870 (VAS assessing global allergy symptoms) and 0.937 (VAS assessing allergy symptoms on sleep). Test-retest reliability ICCs ranged between 0.604 and 0.878-"VAS Work" and "VAS asthma" presented the highest ICCs. Moderate/large responsiveness effect sizes were observed-the sleep VAS was associated with lower responsiveness, while the global allergy symptoms VAS demonstrated higher responsiveness.

Conclusion

In MASK-air®, daily monitoring VASs have high intra-rater reliability and moderate-high validity, reliability, and responsiveness, pointing to a reliable measure of symptom loads.

[Pharmacotherapy of allergic rhinitis: position of a clinical pharmacologist]

Pharmacotherapy for allergic rhinitis is based on different categories of drugs used either in monotherapy or in combination regimens. The current clinical guidelines suggest a stepwise approach to pharmacotherapy for allergic rhinitis. The use of intranasal corticosteroids is considered as the preferred second-stage pharmacotherapy. Inadequate control of AR symptoms in first-line therapy is a common problem. Integrated care pathways (ICP), developed taking into account the data obtained about patients using a mobile application, suggest the use of intranasal corticosteroids as the first line of therapy, including in patients with intermittent rhinitis who have not previously received treatment when assessing the condition according to the VAS for more than 5 points, in patients who received earlier treatment when assessing the condition according to the VAS less than 5 points. According to the data in the medical decision support system and continuing medical education UpToDate, inhaled corticosteroids are considered as the first-line drugs for the pharmacotherapy of allergic rhinitis. In terms of pharmacodynamic efficacy, intranasal corticosteroids are comparable to each other. The selection criteria can be considered: the value of systemic absorption; lipophilicity; the start time of the action; frequency of introduction, organoleptic properties; the possibility of influencing non-nasal symptoms. The use of sprays containing both a glucocorticoid and an antihistamine (mometasone furoate/azelastine hydrochloride) opens up additional pharmacotherapeutic possibilities in the treatment of allergic rhinitis.

Seasonal Variation in Generic and Disease-Specific Health-Related Quality of Life in Rhinologic Patients in Southern Finland

Background: Seasonal variation in exacerbations, hospitalisations, and mortality statistics has been reported for some diseases. To our knowledge, however, no published studies exist on the seasonality of health-related quality of life (HRQoL) amongst rhinologic patients. Aims/Objectives: This study, therefore, aimed to investigate the possible seasonal variation in rhinologic patients’ HRQoL using the rhinologic disease-specific Sino-Nasal Outcome Test-22 (SNOT-22) and the generic 15D HRQoL instrument. Material and Methods: We enrolled unselected adult rhinologic patients requiring specialist care at the Helsinki University Hospital in this cross-sectional, questionnaire-based prospective study during four seasons: February (winter), May (spring), August (summer), and November (autumn). Patients received SNOT-22 and 15D questionnaires via post. The Finnish Meteorological Institute supplied climate data from these months. Results: SNOT-22 and 15D data were available for 301 and 298 patients, respectively. We found no statistically significant differences (p = 0.948) between the mean monthly 15D scores or mean SNOT-22 scales. Furthermore, the mean SNOT-22 subscales did not differ between the monthly study periods. Conclusions and Significance: Our study shows that seasonality did not impact rhinologic patients’ SNOT-22 or 15D HRQoL scores. Thus, these questionnaires can be used for follow-up amongst rhinologic patients regardless of season.

Recent development on the use of sublingual immunotherapy tablets for allergic rhinitis

OBJECTIVE

Allergic rhinitis (AR) is an immunoglobulin (Ig) E-mediated inflammatory condition that causes sneezing, nasal congestion, rhinorrhea, and nasal itch. Although subcutaneous immunotherapy for the treatment of AR has been in use and well established as a treatment modality, sublingual immunotherapy (SLIT) is increasingly considered to be the safer and more convenient alternative. Thus, the objective of this review is to describe recent findings pertaining to the use of SLIT tablets (SLIT-T) for AR.

DATA SOURCES

A database search (PubMed.gov) for articles published between January 1, 2017, and February 9, 2021, was conducted using the following key words: "allergic rhinitis," AND-ed "sublingual immunotherapy." Included were randomized placebo-controlled trials. Other experimental design studies were excluded.

STUDY SELECTIONS

A total of 11 randomized placebo-controlled trials were selected for full-text review and included in the analysis. All studies investigated the use of SLIT on patients with seasonal AR (4 tree pollen, 1 grass pollen, and 1 Japanese cedar) or perennial AR (3 house dust mite).

RESULTS

Our review of 7 recently published randomized placebo-controlled trials with 2348 subjects receiving SLIT reported increased efficacy, safety, supportive immunologic parameters (IgE and IgG4 pre- and posttreatment levels), and improved quality of life. All studies excluded subjects with overlapping seasonal or perennial allergens, a history of moderate-to-severe uncontrolled asthma, or reduced lung function.

CONCLUSION

Our review highlights that SLIT is a safe and effective treatment that considerably reduces symptoms and medication requirements in AR and improves quality of life.

Analysis of patient factors associated with hospital visits for allergic rhinitis in Japanese adult patients: A cross-sectional study

OBJECTIVE

Allergic rhinitis (AR) is one of the most common diseases in Japan. However, several AR patients do not seek optimal treatments at clinics/hospitals. This may affect the patient's quality of life and labor productivity. In this study, we assessed the characteristics of the outpatients' AR and factors associated with their hospital visit, using the dataset obtained from a nation-wide survey in Japan.

METHODS

In this cross-sectional study, we used data from the nation-wide 2013 and 2016 Comprehensive Survey of Living Conditions (CSLC) in Japan. We analyzed the data of AR outpatients through logistic regression, using the outcome as the dependent variable, and age groups, sex, household size, educational status, smoking history, alcohol use, household expenditure, psychological distress, quality of sleep, asthma and atopic dermatitis outpatients as explanatory variables.

RESULTS

Among the data of 317,984 outpatients aged between 20 and 79 years in 2016 CSLC survey, the proportion of AR outpatients was significantly less among current smokers (odds ratio (OR); 0.47, 95% confidence interval (CI); 0.43-0.51, P < 0.001) and those with large household sizes (OR; 0.80, 95% CI; 0.72-0.89, P < 0.001). Conversely, the proportion of AR outpatients was significantly more among subjects with a past smoking habit (OR; 1.19, 95% CI; 1.08-1.31, P < 0.001), insufficient sleep (OR; 2.93, 95% CI; 2.52-3.42, P < 0.001), psychological distress (OR; 1.71, 95% CI; 1.62-1.80, P < 0.001), high household expenditures (OR; 1.68, 95% CI; 1.56-1.80, P < 0.001), and asthma and atopic dermatitis outpatients (OR; 8.97, 95% CI; 8.13-9.89 P < 0.001 for asthma and OR; 7.61, 95% CI; 6.76-8.58 P < 0.001 for atopic dermatitis). We observed the same trend using the dataset of 2013 CLSC survey.

CONCLUSION

This study revealed that smoking habit, psychological distress, insufficient sleep, high household expenditures and outpatients with other allergic diseases are the factors associated with AR outpatient visit.

Efficacy and Safety of Guizhi Decoction AssociatedFormulas for Allergic Rhinitis: A Systematic Review

In this study, we aim to evaluate the efficacy and safety of Guizhi Decoction associated formulas for the treatment of allergic rhinitis. A total of seven online databases were searched to collect studies published up to Feb 23rd, 2020. Study quality of each included article was evaluated by the Cochrane Collaboration risk of bias tool. Systematic reviews were conducted based on the Cochrane systematic review method by using RevMan 5.3 Software. Among the included trials, Guizhi Decoction associated formulas alone (or plus Western medicine, or acupoint-based therapy) were main therapies in experimental groups. Interventions in control groups include Western medicine, Guizhi Decoction associated formulas alone, Chinese patent medicine, and placebo control. Primary outcomes in this study include recovery rate, accumulative marked effective rate, accumulative effective rate, and recurrence rate. Finally, 23 trials involving 2281 participants were included. Results of systematic reviews show that Guizhi Decoction and associated formulas alone, plus Western medicine or plus acupoint-based therapies, were significantly better compared with using Western medicine alone in terms of efficacy. In addition, the formulas plus nasal TCM fumigation therapy could improve effective rate for AR treatment compared to using the formulas alone. More types and cases of adverse events were reported in the control groups (Western medicine alone), but events of included trials were all mild and did not need specific medical intervention. More RCTs of high quality, and large sample size, with appropriate blinding methods or nonblinded pragmatic trials of Guizhi Decoction and associated formulas for AR are needed.

Allergic Rhinitis and Depression: Profile and Proposal

In addition to nasal symptoms, patients with allergic rhinitis (AR) often experience mental and psychological disorders such as depression. Depression not only makes the treatment of AR more difficult and expensive but also poses a serious impact on the patients' daily activities and quality of life, thus bringing additional burden to the families and the society. Here we systematically review the recent research advances in the correlation between AR and depression, analyze the possible causes and mechanisms of depression in AR, summarize the current diagnosis and treatment strategies, and provide our insights into the AR-related depression; in addition, we introduce briefly the basic research status on AR-related depression. We hope that this review article will provide evidence for future studies.

Case Report: Off-Label Use of Omalizumab in a 6-Year-Old Boy With ASD Ameliorated Severe Allergic Rhinitis and Subsequently Improved Behavioral Symptoms

Children with ASD have elevated risk for developing allergic symptoms. The severity of allergic symptoms can exacerbate behavioral problems in children with ASD. Omalizumab, an anti-IgE antibody, has previously shown efficacy in treating allergic rhinitis and behavioral problems in a 12-year-old child with ASD. The present case report provides robust characterization of behavioral improvement in a 6-year-old child with ASD, allergic rhinitis, and autoimmune disorder. A 6-year-old boy with ASD and Hashimoto's disease presented to the clinic with severe allergic rhinitis, irritability, and language delay. After other treatments failed to improve symptoms, our patient was treated with omalizumab at 300 mg/month via subcutaneous injection for a total of 6 months. Marked improvement in allergic symptoms were observed at 2 months into treatment and were maintained through the treatment period. At the conclusion of the treatment period, results from multiple behavioral questionnaires, including the SRS-2, ABC, RBS-R, and PSQI, demonstrated substantial improvement in ASD-related behavioral symptoms. In this case, omalizumab markedly improved ASD-related and sleep behavior in a 6-year-old with ASD, allergic rhinitis, and autoimmune disorder. Future studies with larger patient populations are warranted to investigate the efficacy of omalizumab in patients with ASD and allergy symptoms.

Treatment of allergic rhinitis during and outside the pollen season using mobile technology. A MASK study

Background

The analysis of mobile health (mHealth) data has generated innovative insights into improving allergic rhinitis control, but additive information is needed. A cross-sectional real-world observational study was undertaken in 17 European countries during and outside the estimated pollen season. The aim was to collect novel information including the phenotypic characteristics of the users.

Methods

The Allergy Diary–MASK-air–mobile phone app, freely available via Google Play and App, was used to collect the data of daily visual analogue scales (VASs) for overall allergic symptoms and medication use. Fluticasone Furoate (FF), Mometasone Furoate (MF), Azelastine Fluticasone Proprionate combination (MPAzeFlu) and eight oral H1-antihistamines were studied. Phenotypic characteristics were recorded at entry. The ARIA severity score was derived from entry data. This was an a priori planned analysis.

Results

9037 users filled in 70,286 days of VAS in 2016, 2017 and 2018. The ARIA severity score was lower outside than during the pollen season. Severity was similar for all treatment groups during the pollen season, and lower in the MPAzeFlu group outside the pollen season. Days with MPAzeFlu had lower VAS levels and a higher frequency of monotherapy than the other treatments during the season. Outside the season, days with MPAzeFlu also had a higher frequency of monotherapy. The number of reported days was significantly higher with MPAzeFlu during and outside the season than with MF, FF or oral H1-antihistamines.

Conclusions

This study shows that the overall efficacy of treatments is similar during and outside the pollen season and indicates that medications are similarly effective during the year.

Determinants of the utilization of allergy management measures among hay fever sufferers: a theory-based cross-sectional study

Background

The quality of life of chronically ill individuals, such as hay fever sufferers, is significantly dependent on their health behavior. This survey aimed to explain the health-related behavior of allergic individuals using the protection motivation theory (PMT) and the transtheoretical model (TTM).

Methods

The influencing variables stated by PMT were operationalized based on data from semistructured pilot interviews and a pretest with 12 individuals from the target population. The final questionnaire inquired perceived seriousness and severity of hay fever, response efficacy, response costs, self-efficacy, and the use of various hay fever management measures in relation to the TTM stages. Multivariate logistic regression was performed to investigate the relationships between the PMT constructs and the examined health behavior.

Results

A total of 569 allergic individuals completed the online questionnaire. Only 33.26% of allergic individuals were in the maintenance stage for treatment under medical supervision, and almost 60% preferred hay fever self-management. A total of 67.56% had a well-established habit of taking anti-allergic medication, but only 25.31% had undergone specific immunotherapy. The likelihood of seeking medical supervision was positively influenced by perceived severity (OR = 1.35, 95% CI: 1.02–1.81), perceived seriousness (OR = 2.12, 95% CI: 1.56–2.89), and self-efficacy (OR = 4.52, 95% CI: 3.11–6.65). The perceived severity of symptoms predicted the practice of hay fever self-management (OR = 1.60, 95% CI: 1.21–2.11), as well as anti-allergic medication intake (OR = 1.65, 95% CI: 1.16–2.35). The latter measure was also positively influenced by self-efficacy (OR = 1.52, 95% CI: 1.01–2.28) and hay fever self-management (OR = 4.76, 95% CI: 2.67–7.49). Undergoing specific immunotherapy was significantly predicted only by medical supervision (OR = 9.80, 95% CI: 8.16–13.80). Allergen avoidance was a strategy used by allergic individuals who preferred hay fever self-management (OR = 2.56, 95% CI: 1.87–3.52) and experienced notable symptom severity (OR = 2.12, 95% CI: 1.60–2.81).

Conclusion

Educational interventions that increase the awareness of health risks associated with inadequate hay fever management and measures to increase self-efficacy might be beneficial for the promotion of appropriate hay fever management among allergic individuals.

Psychological profiles of patients with suspected drug allergy

Background

Several studies demonstrate an important association between allergic diseases and patients' psychological characteristics.

Objective

To evaluate any differences in the psychological characteristics of patients studied for suspected drug allergy in comparison with healthy controls. A secondary aim was to assess differences between patients with confirmed versus excluded drug allergy, with respect to the clinical aspects.

Methods

The psychological characteristics of 115 consecutive patients >16 years-old, studied for suspected drug allergy were assessed. They were compared with healthy controls. Four validated questionnaires were used to evaluate anxiety, depression, alexithymia, and personality type.

Results

Eighty-eight patients completed the evaluation: 34 had confirmed drug allergy and 33 excluded. Forty-eight healthy subjects filled the 4 questionnaires. Increased neuroticism was associated with increased odds of belonging to the excluded drug allergy group (odds ratio [OR], 1.374; 95% confidence interval [CI], 1.173–1.609). Increased neuroticism (OR, 1.244; 95% CI, 1.065–1.453) and increased anxiety (OR, 1.210; 95% CI, 1.084–1.351) were associated with increased odds of confirmed drug allergy. However, higher extraversion decreased this likelihood (OR, 0.755; 95% CI, 0.643–0.888). The odds of having confirmed drug allergy was reduced by 79.7% (OR, 0.203; 95% CI, 0.060–0.694) for patients with 2 suspected drugs and by 84.6% (OR, 0.154; 95% CI, 0.029–0.809) for those with ≥3 in comparison to those with only one. Patients with moderate to severe reactions were more likely to have confirmed drug allergy (OR, 4.295; 95% CI, 1.105–16.693) than those with milder manifestations.

Conclusion

Our results highlight that patients with drug allergy have a distinctive psychological profile. Psychological assessment may help to identify patients that would benefit from a targeted intervention.

House Dust Mite Related Allergic Rhinitis and REM Sleep Disturbances

PURPOSE

Sleep disturbances are common in patients with allergic rhinitis (AR). Perennial allergens like house dust mites (HDM) are difficult to avoid and have nocturnal impacts on the respiratory system and Quality of Life (QOL). The Rapid Eye Movement (REM) sleep stage is associated with memory, cognition, dreams, and overall restfulness, which can be impaired in AR patients with Sleep Disordered Breathing (SDB) even when normal all-night apnea-hypopnea (AHI) or respiratory disturbance (RDI) indices are noted on polysomnography (PSG). We hypothesized that AR HDM allergen positive patients would show REM-specific SDB reflected in their objectively elevated REM-RDI values.

MATERIALS AND METHODS

This retrospective analysis of 100 patients included 47 with HDM positive allergy testing. All patients underwent PSG testing calculating the RDI during REM. Multivariate logistic regression models evaluated relationships between allergic statuses and sleep parameters while controlling for potential confounders.

RESULTS

Compared with allergy negative patients, HDM allergen positive patients were significantly more likely (OR 4.29, 95%CI 1.26-14.62) to have a REM-RDI in the moderate/severe range (≥15 events/h).

CONCLUSIONS

Our study highlighted the significance of respiratory allergies to HDM in patients with SDB. We revealed a significant relationship between HDM allergen positivity and SDB characterized by elevated REM-RDI regardless of all-night AHI, RDI, or REM-AHI values. Clinical implications of knowing about disturbed REM and/or HDM allergenicity include better preparation, treatment, outcomes, and QOL for allergic, SDB, and upper airway surgery patients.

Montelukast use over the past 20 years: monitoring of its effects and safety issues

Montelukast, a leukotriene receptor antagonist, was launched 20 years ago in Korea. It is recommended as an alternative treatment for asthma in children with mild persistent symptoms or as an add-on treatment to existing low-dose inhaled corticosteroids (ICSs) in children who require additional treatment. However, in the real-world setting, many doctors and patients prefer montelukast over ICSs despite their lower efficacy. Although montelukast is considered to be a safe drug, there are concerns regarding adverse drug reactions, including the rare occurrence of Churg-Strauss syndrome and, despite insufficient data, the possibility of neuropsychiatric events such as anxiety, depression, sleep disturbance, and suicidality. This review identified that montelukast has significantly contributed to asthma control over the past 20 years in Korea and has been critical for reducing asthma severity, especially early wheezing and disease control. Our findings suggest that the effects of montelukast treatment can be monitored by measuring serum eosinophilderived neurotoxin levels.

Intranasal antihistamine is superior to oral H1 antihistamine as an add-on therapy to intranasal corticosteroid for treating allergic rhinitis

BACKGROUND

Currently, a combination of intranasal corticosteroid (INCS) plus oral H₁ antihistamine (OAH) or intranasal H₁ antihistamine (INAH) therapy is frequently used in the treatment of allergic rhinitis (AR). The superiority of the 2 combined treatments needs to be further examined.

OBJECTIVE

To identify the better of the 2 therapeutic strategies for treating AR.

METHODS

A literature review was performed on MEDLINE, Cochrane Library, and EMBASE databases. Following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses, meta-analyses of the total nasal symptom scores and individual nasal symptom scores were pooled based on studies that compared concomitant H₁ antihistamines plus INCS with INCS alone in the treatment of AR. The pooled results were expressed as weighted mean differences between the treatments. For each selected study, we calculated the relative clinical impact based on the total nasal symptom scores as follows: 100 × (Score_Monotherapy - Score_{Combined therapy}) / Score_Monotherapy.

RESULTS

A total of 13 publications met our selection criteria, with 5066 patients. The pooled results revealed no significant weighted mean difference on the total nasal symptom scores between concomitant OAH plus INCS and INCS alone. As for the individual symptoms, the most common symptom that revealed remission was rhinorrhea, which was after OAH in combination with INCS. The combination therapy of INAH and INCS was superior to INCS alone. In an indirect comparison, the weighted mean relative clinical impact of INAH plus INCS was significantly higher than that of OAH plus INCS.

CONCLUSION

Intranasal H₁ antihistamines have an add-on effect on intranasal corticosteroids, and the combination of intranasal H₁ antihistamines plus intranasal corticosteroid is superior to that of oral H₁ antihistamines plus intranasal corticosteroid in improving nasal symptoms for patients with AR.

Managing Allergic Rhinitis in the Pharmacy: An ARIA Guide for Implementation in Practice

The paradigm of how we manage allergic rhinitis is shifting with a growing understanding that it is a complex process, requiring a coordinated effort from healthcare providers and patients. Pharmacists are key members of these integrated care pathways resolving medication-related problems, optimizing regimens, improving adherence and recommending therapies while establishing liaisons between patients and physicians. Community pharmacists are the most accessible healthcare professionals to the public and allergic rhinitis is one of the most common diseases managed by pharmacists. Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines developed over the past 20 years have improved the care of allergic rhinitis patients through an evidence-based, integrated care approach. In this paper, we propose an integrated approach to allergic rhinitis management in community pharmacy following the 2019 ARIA in the pharmacy guidelines.

Tussilagone inhibits allergic responses in OVA-induced allergic rhinitis guinea pigs and IgE-stimulated RBL-2H3 cells

Farfarae Flos is the dried flower buds of Tussilago farfara L. which is widely used to treat allergic and inflammatory diseases in Chinese folk. Tussilagone (TSL), a sesquiterpene compound purified from Farfarae Flos, has been confirmed the main active component in the plant. However, its anti-allergic activity hasn't been reported yet. The purpose of this study is to investigate the anti-allergic effect of TSL in ovalbumin (OVA)-induced allergic rhinitis (AR) guinea pigs and immunoglobulin E (IgE)-stimulated RBL-2H3 cells. The AR symptoms such as nasal scratching, sneezing and runny nose were scored and the histological changes of nasal mucosa were observed by H&E staining. The levels of histamine, OVA-specific IgE, IL-6 and TNF-α in the serum were measured by ELISA. In IgE-stimulated RBL-2H3 cells, the phosphoryration of Lyn, Syk, Akt, NF-κB p65, ERK and p38 MAPK were investigated by western blot analysis. The results showed that intraperitoneal injection of TSL at doses of 25 and 50 mg/kg significantly alleviated the allergic symptoms and the histological changes of nasal mucosa in OVA-induced allergic rhinitis guinea pigs. Moreover, the levels of histamine, IgE and IL-6 in the serum decreased significantly (p < .05). In vitro, TSL suppressed the phosphorylation of Lyn, Syk, Akt, NF-κB p65, ERK and p38 MAPK in IgE-stimulated RBL-2H3 cells. These results indicate TSL has therapeutic effect on allergic rhinitis in guinea pigs. The anti-allergic mechanism may be through the inhibition of allergic and inflammatory related pathways in mast cells.

ARIA guideline 2019: treatment of allergic rhinitis in the German health system

Background: The number of patients affected by allergies is increasing worldwide. The resulting allergic diseases are leading to significant costs for health care and social systems. Integrated care pathways are needed to enable comprehensive care within the national health systems. The ARIA (Allergic Rhinitis and its Impact on Asthma) initiative develops internationally applicable guidelines for allergic respiratory diseases. Methods: ARIA serves to improve the care of patients with allergies and chronic respiratory diseases. In collaboration with other international initiatives, national associations and patient organizations in the field of allergies and respiratory diseases, real-life integrated care pathways have been developed for a digitally assisted, integrative, individualized treatment of allergic rhinitis (AR) with comorbid asthma. In the present work, these integrated care pathways have been adapted to the German situation and health system. Results: The present ICP (integrated care pathway) guideline covers key areas of the care of AR patients with and without asthma. It includes the views of patients and other healthcare providers. Discussion: A comprehensive ICP guideline can reflect real-life care better than traditional guideline models.

The impact of perennial allergic rhinitis with/without allergic asthma on sleep, work and activity level

Background

Allergic respiratory diseases such as allergic rhinitis (AR) and allergic asthma (AA) are common conditions that can influence sleep and daytime functioning. However, the significance of this impact is unclear—particularly in perennial allergy sufferers. This study investigates the impact of perennial allergy on sleep, daily activities and productivity.

Methods

Adults with self-reported or physician-diagnosed perennial AR aged ≥ 18 years were recruited in Denmark, France, Germany and Sweden. Allergy sufferers were identified using online panels closely matching national population characteristics for each country. Impact on sleep, work, productivity and activity (by the Work, Productivity and Activity Index) were analysed. Descriptive analyses were conducted.

Results

In total, 511 subjects with perennial AR (47.4% also with seasonal allergy) completed the survey. Most subjects (77.5%) had a physician-diagnosis of AR; 46.4% were diagnosed with both AA and AR. Most subjects (65.2%) reported sensitisation to house dust mites. Of all subjects, 66.0% reported sleep problems. Subjects with sleep problems woke, on average, 3.8 times per night, with 92.0% taking 15+ min to fall asleep (22.2% took 60+ min). Upon waking at night, 40.8% struggled to get back to sleep, and 69.2% had difficulties waking in the morning due to tiredness. Disturbances in daily functioning due to sleep issues were reported in 85.5–95.0% of subjects with sleep problems across all aspects investigated. Overall work and activity impairment were 53.3% and 47.1%, respectively. Sleep issues were more frequent (78.1% vs 54.7%) in those diagnosed with both AR and AA compared to AR alone, and more burdensome, with a greater impact on daily functioning (47.0% vs 33.3%) and impairment in work and activity (62.0% and 54.9% vs 39.3% and 35.2%, respectively). Of all subjects, 20.5% were receiving AIT at the time of the survey; of these, 36.4% reported moderate or great improvement in sleep due to allergy treatment.

Conclusions

In perennial AR sufferers, sleep problems are common and impact on daily functioning, with results indicating a greater burden in those with both AR and AA compared to AR alone.

Highlights and recent developments in airway diseases in EAACI journals (2018)

The European Academy of Allergy and Clinical Immunology (EAACI) supports three journals: Allergy, Pediatric Allergy and Immunology, and Clinical and Translational Allergy. EAACI's major goals include supporting the promotion of health, in which the prevention of allergy and asthma plays a critical role, and disseminating the knowledge of allergic disease to all stakeholders. In 2018, the remarkable progress in the identification of basic mechanisms of allergic and respiratory diseases as well as the translation of these findings into clinical practice were observed. Last year's highlights include publication of EAACI guidelines for allergen immunotherapy, many EAACI Position Papers covering important aspects for the specialty, better understanding of molecular and cellular mechanisms, identification of biomarkers for disease prediction and progress monitoring, novel prevention and intervention studies, elucidation of mechanisms of multimorbidities, introduction of new drugs to the clinics, recently completed phase three clinical studies, and publication of a large number of allergen immunotherapy studies and meta-analyses.

Next-generation Allergic Rhinitis and Its Impact on Asthma (ARIA) guidelines for allergic rhinitis based on Grading of Recommendations Assessment, Development and Evaluation (GRADE) and real-world evidence

The selection of pharmacotherapy for patients with allergic rhinitis aims to control the disease and depends on many factors. Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidelines have considerably improved the treatment of allergic rhinitis. However, there is an increasing trend toward use of real-world evidence to inform clinical practice, especially because randomized controlled trials are often limited with regard to the applicability of results. The Contre les Maladies Chroniques pour un Vieillissement Actif (MACVIA) algorithm has proposed an allergic rhinitis treatment by a consensus group. This simple algorithm can be used to step up or step down allergic rhinitis treatment. Next-generation guidelines for the pharmacologic treatment of allergic rhinitis were developed by using existing GRADE-based guidelines for the disease, real-world evidence provided by mobile technology, and additive studies (allergen chamber studies) to refine the MACVIA algorithm.

Allergic rhinitis increases the risk of incident panic disorder among young individuals: A nationwide population-based cohort study in Taiwan

BACKGROUND

Studies have reported an association between allergy and panic disorder. However, few studies have explored the relationship between allergic rhinitis and panic disorder. Previous studies were limited by cross-sectional study designs, self-reported symptoms, absence of matched controls, and lack of consideration of the influence of steroid and comorbidities. This study aimed to explore the longitudinal association between allergic rhinitis and panic disorder in a large population-based cohort of young people.

METHODS

In this study, 79,917 new cases of allergic rhinitis between 1998 and 2012 in individuals younger than 20 years were identified from Taiwan's National Health Insurance Research Database. One control (nonallergic rhinitis) per case (allergic rhinitis) was randomly selected from the remaining sample, matching for age, sex, residence, and insurance premium. Both groups were followed until the end of 2013 for incidence of panic disorder. Cox regression analysis was performed, adjusting for sex, age, residence, insurance premium, systemic steroids, asthma, atopic dermatitis, allergic conjunctivitis, attention deficit hyperactivity disorder, depression, and Charlson index.

RESULTS

Allergic rhinitis was associated with a 2-fold increase in risk for panic disorder after adjustment for other variables. Additional independent risk factor of panic disorders were female sex, older age group, and depression.

LIMITATIONS

Lifestyle, substance use, smoking by the patient or family members, and psychosocial stressors were not evaluated.

CONCLUSIONS

Allergic rhinitis was associated with increased risk of panic disorder. Assessment and intervention of allergy rhinitis among young people with panic disorder are critical.

Vilnius Declaration on chronic respiratory diseases: multisectoral care pathways embedding guided self-management, mHealth and air pollution in chronic respiratory diseases

Background

Over 1 billion people suffer from chronic respiratory diseases such as asthma, COPD, rhinitis and rhinosinusitis. They cause an enormous burden and are considered as major non-communicable diseases. Many patients are still uncontrolled and the cost of inaction is unacceptable. A meeting was held in Vilnius, Lithuania (March 23, 2018) under the patronage of the Ministry of Health and several scientific societies to propose multisectoral care pathways embedding guided self-management, mHealth and air pollution in selected chronic respiratory diseases (rhinitis, chronic rhinosinusitis, asthma and COPD). The meeting resulted in the Vilnius Declaration that was developed by the participants of the EU Summit on chronic respiratory diseases under the leadership of Euforea.

Conclusion

The Vilnius Declaration represents an important step for the fight against air pollution in chronic respiratory diseases globally and has a clear strategic relevance with regard to the EU Health Strategy as it will bring added value to the existing public health knowledge.
