The Allergic Rhinitis and its Impact on Asthma (ARIA) score of allergic rhinitis using mobile technology correlates with quality of life: The MASK study

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

Work productivity in rhinitis using cell phones: The MASK pilot study

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

Allergic rhinitis causes loss of smell in children: The OLFAPEDRIAL study

BACKGROUND

The objective of the OLFAPEDRIAL study was to assess the olfactory dysfunction in allergic paediatric population, which has been scarcely studied.

METHODS

Observational, cross-sectional and multicentre study evaluated the sense of smell in untreated allergic rhinitis (AR) paediatric patients aged 6-12 years.

RESULTS

Forty-four per cent (551 of 1260) of children with AR reported smell dysfunction, with both loss of smell frequency (52.1%, p < 0.001) and intensity (0.75 ± 0.84, p < 0.0001) being more frequent in patients with persistent than intermittent AR (38.0% and 0.51 ± 0.73, respectively). In addition, both loss of smell frequency and intensity increased according to disease severity (m-ARIA classification) but always being significantly higher in persistent (p < 0.0001) than in intermittent AR.

CONCLUSIONS

Children with allergic rhinitis present a mild-moderate loss of smell frequency and intensity which is clearly related to the disease duration and severity. The loss of smell can be considered, as in adults, a clinical marker of disease severity.

MACVIA clinical decision algorithm in adolescents and adults with allergic rhinitis

The selection of pharmacotherapy for patients with allergic rhinitis (AR) depends on several factors, including age, prominent symptoms, symptom severity, control of AR, patient preferences, and cost. Allergen exposure and the resulting symptoms vary, and treatment adjustment is required. Clinical decision support systems (CDSSs) might be beneficial for the assessment of disease control. CDSSs should be based on the best evidence and algorithms to aid patients and health care professionals to jointly determine treatment and its step-up or step-down strategy depending on AR control. Contre les MAladies Chroniques pour un VIeillissement Actif en Languedoc-Roussillon (MACVIA-LR [fighting chronic diseases for active and healthy ageing]), one of the reference sites of the European Innovation Partnership on Active and Healthy Ageing, has initiated an allergy sentinel network (the MACVIA-ARIA Sentinel Network). A CDSS is currently being developed to optimize AR control. An algorithm developed by consensus is presented in this article. This algorithm should be confirmed by appropriate trials.

Leukotriene receptor antagonists in allergic eye disease: a systematic review and meta-analysis

BACKGROUND

Allergic eye diseases are common and cause significant morbidity. Leukotrienes are implicated in the pathogenesis of seasonal and perennial allergic conjunctivitis (AC), commonly seen in conjunction with allergic rhinitis, and in vernal keratoconjunctivitis and atopic keratoconjunctivitis.

OBJECTIVES

To assess the available evidence for an effect of leukotriene receptor antagonists (LTRAs) on the ocular symptoms of allergic eye diseases.

METHODS

Selected studies, identified with systematic review search methods, were single/double-blind, randomized, controlled trials that compared LTRAs with other common treatments.

RESULTS

Eighteen trials, using the LTRA montelukast (in AC only), were identified. Six studies were suitable for meta-analysis, in patients with seasonal AC [treated over a 2-week period, symptoms scored 0 (mild) to 3 (severe)]. These trials were at low risk of bias without significant heterogeneity. Six trials were analyzed and showed that montelukast improved patients' ocular symptoms to a greater extent than placebo, with a difference in mean change-from-baseline score of -0.10 (95% CI, -0.14 to -0.07; P < .00001). Three trials compared montelukast with oral antihistamine. The difference in mean change-from-baseline score was 0.08 (95% CI, 0.02 to 0.14; P = .007), in favor of antihistamines. Two trials compared montelukast and oral antihistamine with placebo. The difference in mean change-from-baseline score was -0.30 (95% CI, -0.38 to -0.21; P < .00001), in favor of combination treatment.

CONCLUSIONS

In seasonal AC LTRAs are more efficacious than placebo but less efficacious than oral antihistamines in adult patients. Clinical trials should be conducted to determine whether combination treatment with LTRA and oral antihistamine has a synergistic effect. Further research is required to clarify the role of LTRAs in other allergic eye diseases.
