Clinical usefulness of a guideline-based screening tool for the diagnosis of allergic rhinitis in asthmatics: the Self Assessment of Allergic Rhinitis and Asthma questionnaire

Daytime and Nighttime Visual Analog Scales May Be Useful in Assessing Asthma Control Levels Before and After Treatment

PURPOSE

Few questionnaires evaluate daytime and nighttime symptoms separately, although these assessments could contribute to the improvement of disease control levels and prevention of future risks in asthma. The purpose of this retrospective study was to investigate whether daytime and nighttime visual analog scales (VAS) are useful in measuring the perception of symptoms, assessing disease control levels, and evaluating the treatment effects in asthma.

PATIENTS AND METHODS

Self-reporting asthma control tests (ACT) before and after treatment are standardized tests used to determine disease control levels. A multiple regression analysis was performed to determine the correlation between daytime and nighttime VAS and the characteristics of patients before treatment, as well as the changes in VAS and lung functions and fractional exhaled nitrogen oxide after treatment in 55 treatment-naïve symptomatic adult patients with asthma.

RESULTS

Both daytime (r = -0.57, P < 0.0001) and nighttime (r = -0.46, P < 0.0001) VAS correlated well with ACT scores, and there was a correlation between daytime and nighttime VAS (r = 0.33, P = 0.0148) before treatment. In addition, the changes in daytime (r = -0.65, P < 0.0001) and nighttime (r = -0.44, P < 0.0001) VAS were significantly associated with changes in the ACT scores. The multiple regression analysis (β [95% confidence interval]) revealed that improvements in the daytime (-2.33 [-4.55 to -0.11], P = 0.0405) and nighttime (-3.09 [-6.25 to 0.07], P = 0.0505) VAS were associated with an increased forced vital capacity after treatment, although there was no correlation between the VAS and characteristics before treatment.

CONCLUSION

Our study demonstrated that daytime and nighttime VAS were useful in assessing disease control levels and evaluating the treatment effects in asthma.

Control of Allergic Rhinitis and Asthma Test: A systematic review of measurement properties and COSMIN analysis

The Control of Allergic Rhinitis and Asthma Test (CARAT) is a patient-reported outcome measurement (PROM) assessing the control of asthma and allergic rhinitis (AR) at a 4 week interval. This systematic review aimed to evaluate the measurement properties of CARAT. Following PRISMA and COSMIN guidelines, we searched five bibliographic databases and retrieved studies concerning the development, assessment of properties, validation, and/or cultural adaption of CARAT. The studies' methodological quality, the quality of measurement properties, and the overall quality of evidence were assessed. We performed meta-analysis of CARAT measurement properties. We included 16 studies. Control of Allergic Rhinitis and Asthma Test displayed sufficient content validity and very good consistency (meta-analytical Cronbach alpha = 0.83; 95% CI = 0.80-0.86;I²  = 62.6%). Control of allergic rhinitis and Asthma Test meta-analytical intraclass correlation coefficient was 0.91 (95% CI = 0.64-0.98;I²  = 93.7%). It presented good construct validity, especially for correlations with Patient-reported outcome measures assessing asthma (absolute Spearman correlation coefficients range = 0.67-0.73; moderate quality of evidence), and good responsiveness. Its minimal important difference is 3.5. Overall, CARAT has good internal consistency, reliability, construct validity and responsiveness, despite the heterogeneous quality of evidence. Control of Allergic Rhinitis and Asthma Test can be used to assess the control of asthma and AR. As first of its kind, this meta-analysis of CARAT measurement properties sets a stronger level of evidence for asthma and/or AR control questionnaires.

Effect of Japanese Cedar Pollen Sublingual Immunotherapy on Asthma Patients with Seasonal Allergic Rhinitis Caused by Japanese Cedar Pollen

Allergen immunotherapy is a promising treatment for allergic diseases that induce immune tolerance through the administration of specific allergens. In this study, we investigate the efficacy of sublingual immunotherapy (SLIT) in asthmatic patients with SAR-JCP and the dynamics of the parameters before and after treatment in a real-world setting. This was a prospective single-center observational study. Patients with asthma and SAR-JCP (n = 24) were recruited for this study and assessed using symptom questionnaires before SLIT and a year after the SLIT. In addition, a respiratory function test, forced oscillation technique, and blood sampling test were performed during the off-season before and after SLIT. The one-year SLIT for asthma patients with SAR-JCP significantly improved not only allergic rhinitis symptoms, but also asthma symptoms during the JCP dispersal season, and significantly improved airway resistance during the off-season. The change in the asthma control test and the visual analog scale score during the season before and after SLIT was negatively and positively correlated with the change in peripheral blood γδ T cells off-season before and after SLIT, respectively. It was suggested that improvement in asthma symptoms during the JCP dispersal season after SLIT was associated with reduced peripheral blood γδ T cells.

Surveillance of pollen-food allergy syndrome in elementary and junior high school children in Saitama, Japan

Background

Because few studies have epidemiologically evaluated pollen-food allergy syndrome (PFAS), relevant information about this disease is limited in children.

Objective

We wanted to clarify the epidemiological details of PFAS by creating a questionnaire which enables to distinguish class 2 food allergy from that of class 1.

Methods

We conducted a questionnaire survey for schoolchildren attending to public elementary and junior high schools. In this questionnaire, we asked about both the allergy to fruits and/or vegetables and allergic rhinitis (AR). PFAS was, then, defined as allergy for fruits and/or vegetable which occurred after the symptoms of AR appeared.

Results

A total of 2,346 children (median age, 10.6±2.5 years; 1,157 boys) were evaluated. The prevalence of PFAS was 6.9% among subjects. The mean ages in the onset of AR and PFAS were 4.59±2.76 and 7.38±3.17 years old, respectively. Various kinds of foods were shown to be causative, among which kiwifruits were the commonest. As high as approximately 30% of children with PFAS experienced systemic symptoms including cutaneous (21.8%) and respiratory symptoms (9.6%). Anaphylaxis was diagnosed in 5.8% children.

Conclusion

Our results indicated that the prevalence of PFAS was getting higher and the mean age of onset was getting lower. These may be attributed to the increasing number of patients with AR and also to the lower age of onset of AR. We have to be careful to not only local but also systemic symptoms when examining children with PFAS.

Retrospective Study of the Effects of Post-nasal Drip Symptoms on Cough Duration

BACKGROUND/AIM

The aim of this study was to elucidate the significance of allergic rhinitis and post-nasal drip symptoms in patients with cough-variant and cough-predominant asthma.

PATIENTS AND METHODS

We conducted a retrospective analysis of 91 patients who had cough-variant or cough-predominant asthma and first visited the Nakajima Medical Clinic in Japan between June 2012 and July 2015.

RESULTS

Post-nasal drip symptoms were reported in 58 (63.7%) patients. The patients with post-nasal drip symptoms (19.5±8.3 days) had a significantly longer time until cough disappearance than those without post-nasal drip symptoms (11.0±4.8 days) (p=0.000034). Multivariate analysis showed that post-nasal drip symptoms are independent prolonged factors of cough duration.

CONCLUSION

Post-nasal drip symptoms may affect cough control in patients with cough-variant and cough-predominant asthma.

[Diagnosis of allergy in asthma]

Allergy is a hypersensitivity reaction induced by immunological mechanisms. In asthma, allergy has a complex role and is usually IgE mediated. Allergy must be evaluated during the work up but evidence of IgE sensitivity does not mean that allergens play a role in the pathophysiology of the disease. The clinical relevance of the sensitivity has to be considered. This paper describes current available tools to screen for IgE sensitivity, allergen exposure and their role in asthma.

The nationwide program of allergic disease prevention as an implementation of GARD guidelines in Poland

Background

In 2006, the Global Alliance against Chronic Respiratory Diseases (GARD) was established. The GARD strategy is based mainly on activities aimed at implementing preventive tasks at a local and global level. In Poland, the National Health Program (NHP) is the strategic document describing the tasks of governmental and local administration in the field of public health. One of the activities under the NHP is a project to carry out mass allergy screening (of children and adolescents at school age) and to organize an information and education campaign.

Methods

In 2017-2018, the screening will cover a group of at least 10,000 children and adolescents at school age (6-18 years of age) in 10 of 16 voivodships in Poland. In the study, the e-health tool for early pre-medical risk assessment of allergic diseases was used. The algorithm determines the risk of bronchial asthma (BA) and allergic rhinitis (AR) based on a series of 38 questions on the symptoms of allergic diseases. In order to assess the effectiveness of the screening test (algorithm) a validation study was carried out before screening. Moreover, the algorithm was calibrated on the basis of the obtained results. The screening is accompanied by a nationwide information and education campaign carried out by means of new media.

Results

A total of 1,008 children and adolescents participated in the validation study. In outpatient examination AR was diagnosed in 46.4% and BA in 11.2%. In the case of AR, the sensitivity of the calibrated version of the algorithm was 0.852 and the specificity was 0.840. In the case of BA, it was 0.841 and 0.912, respectively. In 2017, 1,512 people used the screening tool, of which 1,472 respondents went through all stages of the assessment. BA positive AR result (probably sick) was found in 19.5% of respondents and BA in 8.4%.

Conclusions

The use of e-health tools in mass screening and new media to conduct information and education campaigns allows for the reduction of costs and for efficient implementation of activities. It is important to popularize the use of this type of solutions both at national and local level.

Self-assessment of Allergic Rhinitis and Asthma (SACRA) Questionnaire-based Allergic Rhinitis Treatment Improves Asthma Control in Asthmatic Patients with Allergic Rhinitis

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

ARIA 2016: Care pathways implementing emerging technologies for predictive medicine in rhinitis and asthma across the life cycle

The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative commenced during a World Health Organization workshop in 1999. The initial goals were (1) to propose a new allergic rhinitis classification, (2) to promote the concept of multi-morbidity in asthma and rhinitis and (3) to develop guidelines with all stakeholders that could be used globally for all countries and populations. ARIA—disseminated and implemented in over 70 countries globally—is now focusing on the implementation of emerging technologies for individualized and predictive medicine. MASK [MACVIA (Contre les Maladies Chroniques pour un Vieillissement Actif)-ARIA Sentinel NetworK] uses mobile technology to develop care pathways for the management of rhinitis and asthma by a multi-disciplinary group and by patients themselves. An app (Android and iOS) is available in 20 countries and 15 languages. It uses a visual analogue scale to assess symptom control and work productivity as well as a clinical decision support system. It is associated with an inter-operable tablet for physicians and other health care professionals. The scaling up strategy uses the recommendations of the European Innovation Partnership on Active and Healthy Ageing. The aim of the novel ARIA approach is to provide an active and healthy life to rhinitis sufferers, whatever their age, sex or socio-economic status, in order to reduce health and social inequalities incurred by the disease.

Respiratory Diseases in University Students Associated with Exposure to Residential Dampness or Mold

University students are frequently exposed to residential dampness or mold (i.e., visible mold, mold odor, dampness, or water leaks), a well-known contributor to asthma, allergic rhinitis, and respiratory infections. This study aims to: (a) describe the prevalence of these respiratory diseases among university students; and (b) examine the independent contribution of residential dampness or mold to these diseases. An online survey was conducted in March 2014 among the 26,676 students registered at the Université de Sherbrooke (Quebec, Canada). Validated questions and scores were used to assess self-reported respiratory diseases (i.e., asthma-like symptoms, allergic rhinitis, and respiratory infections), residential dampness or mold, and covariates (e.g., student characteristics). Using logistic regressions, the crude and adjusted odd ratios between residential dampness or mold and self-reported respiratory diseases were examined. Results from the participating students (n = 2097; response rate: 8.1%) showed high prevalence of allergic rhinitis (32.6%; 95% CI: 30.6–34.7), asthma-like symptoms (24.0%; 95% CI: 22.1–25.8) and respiratory infections (19.4%; 95% CI: 17.7–21.2). After adjustment, exposure to residential dampness or mold was associated with allergic rhinitis (OR: 1.25; 95% CI: 1.01–1.55) and asthma-like symptoms (OR: 1.70; 95% CI: 1.37–2.11), but not with respiratory infections (OR: 1.07; 95% CI: 0.85–1.36). Among symptomatic students, this exposure was also associated with uncontrolled and burdensome respiratory symptoms (p < 0.01). University students report a high prevalence of allergic rhinitis, asthma-like symptoms and respiratory infections. A common indoor hazard, residential dampness or mold, may play a role in increasing atopic respiratory diseases and their suboptimal control in young adults. These results emphasize the importance for public health organizations to tackle poor housing conditions, especially amongst university students who should be considered “at-risk”.

Co-existence and seasonal variation in rhinitis and asthma symptoms in patients with asthma

BACKGROUND

Asthma and rhinitis are common diseases that often occur concomitantly. However, in patients with asthma, the concurrent assessment of seasonal variation in rhinitis and asthma symptoms has not been comprehensively addressed. We prospectively evaluated seasonal changes in rhinitis and asthma symptoms over one year.

METHODS

Fifty-six patients with asthma were enrolled. Asthma and rhinitis symptoms were assessed by using the State of the Impact of Allergic Rhinitis on Asthma Control (SACRA) questionnaire, developed and validated in Japan by the committee　of Global Initiative for Asthma and the committee of Allergic Rhinitis for asthma and its impact on Asthma.

RESULTS

Fifty-three patients completed the study. Forty-five patients (85%) had nasal symptoms during at least one or more seasons and 15 patients (28%) had perennial rhinitis. The association between asthma symptoms and rhinitis symptoms, assessed by a visual analogue scale (VAS), was significant during each season; seasonal variations of symptoms were synchronous. Uncontrolled asthma was more prevalent in patients with moderate-to-severe rhinitis compared to those with mild rhinitis. The VAS score of asthma symptoms in patients with asthma and perennial rhinitis was significantly higher than that in patients with non-perennial rhinitis or without rhinitis, across every season, except for spring. Correlations were more significantn patients less than 65 years of age than in older patients.

CONCLUSION

Rhinitis is common in patients with asthma. Symptoms of rhinitis and asthma often co-exist, and the association between these symptoms may be stronger n younger patients with asthma than older.

The impact of co-existing seasonal allergic rhinitis caused by Japanese Cedar Pollinosis (SAR-JCP) upon asthma control status

BACKGROUND

Seasonal Allergic Rhinitis Caused by Japanese Cedar Pollinosis (SAR-JCP) is a most common allergic rhinitis, affecting about 40% in Japan, but the influence from SAR-JCP upon asthma is controversial. The purpose of this study is to investigate the effect of coexistence of SAR-JCP upon control status of asthma using SACRA (Self-Assessment of Allergic Rhinitis and Asthma Questionnaire).

METHODS

The design was prospective, single-center, observational study. Asthmatic patients were classified into 3 groups, patients without rhinitis, those with perennial rhinitis or those with SAR-JCP from the results of SACRA. The control status of asthma were evaluated by Visual Analog Scale (VAS) in SACRA and Asthma Control Test (ACT) score. They were evaluated twice, from September to January (nonpollen-season) and February to April (pollen-season) and compared.

RESULTS

451 patients were enrolled and 325 cases (72%) were diagnosed as having comorbidity of rhinitis, among which 173 with only perennial rhinitis, while 152 with SAR-JCP. There was no significant difference in asthma control level measured by VAS and ACT score among 3 groups during nonpollen-season. The asthma control level measured by VAS (1.91-2.95) and ACT score (22.7-21.6) got worse during pollen-season among patients with SAR-JCP, even though 84% received treatment for rhinitis. Although it differed according to criteria, asthma control during pollen-season was impaired in 18-38% asthmatic patients with SAR-JCP.

CONCLUSION

It is possible to minimize the influence of AR on asthma control by obtaining an accurate diagnosis and providing sufficient treatment for rhinitis.

Comparison of intranasal ciclesonide, oral levocetirizine, and combination treatment for allergic rhinitis

Purpose

To evaluate the efficacy and safety of once-daily ciclesonide in comparison to both levocetirizine alone, and a ciclesonide/levocetirizine combination in patients with seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR).

Methods

Subjects exhibiting moderate to severe allergic rhinitis for longer than 1 year were randomized in an open-label, 3-arm, parallel group, multicenter study. Subjects received 200 µg ciclesonide, 5 mg levocetirizine, or a combination of both. Changes from baseline until the end-of-study visit (2 weeks following) were evaluated by reflective total nasal symptom scores (rTNSSs), reflective total ocular symptom scores (rTOSSs), physician-assessed overall nasal signs and symptoms severity (PANS), and rhinoconjunctivitis quality-of-life questionnaires (RQLQ).

Results

Significant improvements in rTNSS, PANS, and RQLQ in the ciclesonide monotherapy group were observed in comparison to the levocetirizine alone group. Three individual symptoms of rTNSS, including runny nose, nasal itching, and congestion, were improved in the ciclesonide-treated group. rTOSS scores for ciclesonide monotherapy improved from baseline, but no superiority over levocetirizine was shown. The absolute score and changes in rTNSS and PANS were positively correlated. Ciclesonide spray was more effective than levocetirizine in reducing nasal symptoms in both SAR and PAR patients. Ciclesonide and levocetrizine were well tolerated alone and in combination.

Conclusions

Our results provide support for an AR and its Impact on Asthma (ARIA) recommendation stipulating that ciclesonide is superior to levocetirizine for the treatment of AR, with tolerable safety. Addition of levocetirizine to ciclesonide did not give further clinical benefit over monotherapy.
