Heterogeneity of sensitization profiles and clinical phenotypes among patients with seasonal allergic rhinitis in Southern European countries-The @IT.2020 multicenter study.

BACKGROUND: Pollen allergy poses a significant health and economic burden in Europe. Disease patterns are relatively homogeneous within Central and Northern European countries. However, no study broadly assessed the features of seasonal allergic rhinitis (SAR) across different Southern European countries with a standardized approach. OBJECTIVE: To describe sensitization profiles and clinical phenotypes of pollen allergic patients in nine Southern European cities with a uniform methodological approach. METHODS: Within the @IT.2020 multicenter observational study, pediatric and adult patients suffering from SAR were recruited in nine urban study centers located in seven countries. Clinical questionnaires, skin prick tests (SPT) and specific IgE (sIgE) tests with a customized multiplex assay (Euroimmun Labordiagnostika, Lübeck, Germany) were performed. RESULTS: Three hundred forty-eight children (mean age 13.1 years, SD: 2.4 years) and 467 adults (mean age 35.7 years SD: 10.0 years) with a predominantly moderate to severe, persistent phenotype of SAR were recruited. Grass pollen major allergenic molecules (Phl p 1 and/or Phl p 5) ranged among the top three sensitizers in all study centers. Sensitization profiles were very heterogeneous, considering that patients in Rome were highly poly-sensitized (sIgE to 3.8 major allergenic molecules per patient), while mono-sensitization was prominent and heterogeneous in other cities, such as Marseille (sIgE to Cup a 1: n = 55/80, 68.8%) and Messina (sIgE to Par j 2: n = 47/82, 57.3%). Co-sensitization to perennial allergens, as well as allergic comorbidities also broadly varied between study centers. CONCLUSIONS: In Southern European countries, pollen allergy is heterogeneous in terms of sensitization profiles and clinical manifestations. Despite the complexity, a unique molecular, multiplex, and customized in-vitro IgE test detected relevant sensitization in all study centers. Nevertheless, this geographical diversity in pollen allergic patients imposes localized clinical guidelines and study protocols for clinical trials of SAR in this climatically complex region.

Contribution of MASK-air® as a mHealth tool for digitally-enabled person-centred care in rhinitis and asthma.

In chronic diseases, mobile health apps may help to (i) improve clinical management and (ii) provide valuable real-world scientific evidence. In allergic rhinitis, a market research study has only identified four mHealth apps which were multilingual, resulted in scientific publications and displayed a comprehensive list of medications. Ot those, MASK-air® was the app with the highest number of scientific publications. MASK-air® has been launched in 2015 and is currently available in 30 countries, having collected data from more than 30,000 users. It comprises a daily monitoring questionnaire, allowing patients to register (i) their daily allergy symptoms by means of visual analogue scales, and (ii) their medication use. The achievements of MASK-air® include the development of two digital biomarkers for daily monitoring of rhinitis and asthma (combined symptom-medication score and electronic daily asthma control score). In addition, MASK-air® data have allowed to assess patients' behaviours, suggesting that patients do not follow guideline recommendations, but rather treat themselves (and often use co-medication) whenever feeling worse. Using MASK-air® data, it has also been possible to quantify the impact of allergic diseases in quality-of-life, school and work productivity. MASK-air® real-world data is being used as a source of evidence for the Allergic Rhinitis and its Impact on Asthma 2024 guidelines, in an innovative process of incorporation of mobile health data into guidelines. This review discusses the clinical and scientific contributions of MASK-air® for person-centred care of rhinitis and asthma, providing an illustrative example on the use of mobile health in chronic diseases.

From MASK-air and SILAM to CATALYSE (Climate Action To Advance HeaLthY Societies in Europe).

Plant species vary under different climatic conditions and the distribution of pollen in the air. Trends in pollen distribution can be used to assess the impact of climate change on public health. In 2015, the Mobile Airways Sentinel networK for rhinitis and asthma (MASK-air®) was launched as a project of the European Innovation Partnership on Active and Healthy Ageing (EIP-on-AHA, DG Santé and DG CONNECT). This project aimed to develop a warning system to inform patients about the onset of the pollen season, namely, the System for Integrated modeLling of Atmospheric coMposition (SILAM). A global-to-meso-scale dispersion model was developed by the Finnish Meteorological Institute (FMI). It provides quantitative information on atmospheric pollution of anthropogenic and natural origins, particularly on allergenic pollens. Impact of Air Pollution on Asthma and Rhinitis (POLLAR, EIT Health) has combined MASK-air clinical data with SILAM forecasts. A new Horizon Europe grant (Climate Action to Advance HeaLthY Societies in Europe [CATALYSE]; grant agreement number 101057131), which came into force in September 2022, aims to improve our understanding of climate change and help us find ways to counteractit. One objective of this project is to develop early warning systems and predictive models to improve the effectiveness of strategies for adapting to climate change. One of the warning systems is focused on allergic rhinitis (CATALYSE Task 3.2), with a collaboration between the FMI (Finland), Porto University (Portugal), MASK-air SAS (France), ISGlobal (Spain), Hertie School (Germany), and the University of Zurich (Switzerland). It is to be implemented with the support of the European Academy of Allergy and Clinical Immunology. This paper reports the planning of CATALYSE Task 3.2.

Understanding beliefs about inhaled medication in patients with persistent asthma: a cross-sectional analysis of the INSPIRERS studies.

Summary: Background. Identifying factors influencing adherence, such as patients' beliefs about medication, is essential for effective asthma management. This study aims to assess and gain insight into the beliefs of patients with asthma regarding inhaled medication. Methods. This is a secondary analysis of the INSPIRERS studies. Patients aged ≥ 13 y.o., with persistent asthma and a prescription for inhaled controller were recruited from 60 primary and secondary care centres in Portugal from 2017 to 2020. Demographic and clinical characteristics were collected in a face-to-face visit. The Specific-Beliefs about Medicine Questionnaire was administered 1-week later by telephone interview. Mann-Whitney U and Kruskal-Wallis tests were used to explore relations between patients' beliefs and characteristics. Results. A total of 552 participants (mean 32.8 ± 17.3 y.o.; 64.5% female) were analysed. The Necessity score (Median 19 [p25-p75 16,22]) was significantly higher than the Concerns score (15 [16,22], p less than 0.001), resulting in a positive Necessity-Concern differential (Median 4 [0,7]). Acceptance (high necessity, low concerns) characterized 61% of participants, while 19% were ambivalent (high necessity, high concerns). Adolescents exhibited lower Necessity (Median 16 vs 20; p less than 0.001) and Concerns scores (Median 11 vs 15; p = 0.002) than adults. In primary care setting, patients had significantly lower Necessity (Median 18 vs 19; p = 0.027) and Concerns (Median 14 vs 15; p = 0.05) compared to the secondary care. Conclusions. A predominantly positive perception of inhaled asthma medication necessity was found, although ambivalence or indifference exists in about 1/5 of patients. Our findings highlight the importance of personalized approaches to address beliefs and optimise patient education.

Self-reported adverse reactions to subcutaneous airborne allergen immunotherapy: a real-life, single center study.

Summary: Background. To estimate the prevalence of self-reported adverse reactions (AdR) to subcutaneous airborne allergen immunotherapy (SCIT) and to describe factors associated with its occurrence. Methods. Real-life, observational, descriptive study of all patients treated with SCIT at a Portuguese allergy unit between 03/2017 and 06/2019, and who answered ≥ 1 time to a pre-SCIT evaluation questionnaire assessing the occurrence of local and/or systemic AdR in the previous administration. Results. 939 questionnaires from 231 patients (42% female, 35% with asthma) were included. Most (60%) SCIT preparations had multiple allergens with concentration adjusted to prevent dilution (MA-NoDil), 26% were single allergen with standard concentration (SA-SC), 10% single allergen with higher than standard concentration (SA-HC), and 4% mixtures without concentration adjustment (MA-Dil). SCIT-related AdR were self-reported in 313 (33%) administrations, 97% at the injection site and 11% grade 1 systemic symptoms. In a multivariable model, being a female and having asthma were associated with higher risk of AdR. MA-NoDil SCIT presented a lower risk of AdR compared to SA-SC SCIT. Conclusions. SCIT-related AdR were self-reported in 1/3 of the administrations, most at the injection site. The risk of AdR was higher in females and in patients with asthma. The lower risk of adverse reactions observed in SCIT preparations with multiple allergens with no dilutional effect should be further explored in future, targeted studies.

ConectAR: Collaborative network of patients with asthma and carers actively involved in health research: a protocol for patient and public involvement.

Summary: Background. Patients and Public Involvement in every stage of the patient-centered health research cycle is the key to the development of innovative solutions with an impact on patients' care. Methods. This protocol describes the development of ConectAR, a network to promote the involvement of patients with asthma and their carers in the health research cycle. Results. This protocol comprehends 4 tasks: 1) define the mission, vision, governance and activities of the network through focus groups; 2) establish the communication strategy and tools; 3) test the feasibility of the network in a Delphi study on the research priorities for asthma in Portugal; 4) coordination and dissemination activities. Conclusions. This network will improve research by ensuring that patients and carers have an active role in the co-creation of impactful solutions for asthma.

Prescribing patterns of medication for respiratory diseases: cluster analysis of the Portuguese electronic prescription database.

Summary: We aimed to describe, for the first time, the prescribing patterns among patients on persistent respiratory treatment, from the Portuguese electronic prescription and dispensing database. This was a one-year retrospective population-based analysis of prescriptions (n = 39810) for medication for respiratory disease and exacerbations. Cluster analysis was applied based on medication and prescribers' specialty. Prescribing patterns were grouped and labelled as: possible medication for asthma and allergic rhinitis (General Practitioners-GPs and allergists to younger patients); COPD (GPs and pulmonologists to older patients); asthma or Asthma-COPD Overlap (GPs and pulmonologists); exacerbation, infection and relievers. This analysis was an important first step to understand the Portuguese reality on the treatment of respiratory diseases.

The use of remote care during the Coronavirus disease 2019 pandemic: a perspective of Portuguese and Spanish physicians.

Summary: This study aimed to characterise how the follow-up of outpatients was done during the first months of COVID-19 pandemic by a multidisciplinary group of physicians involved in an asthma mHealth project. A cross-sectional study based on a web survey was conducted. The survey was sent to 123 physicians working at secondary care centres of Portugal and Spain, that participate in the INSPIRERS project. A total of 65 physicians completed the survey (53% response rate). They had a mean of 18 (11) years of clinical practice and 14% were residents. More than half were allergists (58%), 22% pulmonologists and 20% paediatricians. Most were working in Portugal (89%) and in public hospitals (88%). All were conducting consultations: 71% presential (median [p25 , p75] duration 30 [20, 30] min), 91% telephonic (15 [10, 20] min) and 20% video consultations (20 [10, 28] min). The median duration of presential consultations was significantly higher than pre-COVID-19 (20 [20, 30] min; p = 0.021). From the physicians conducting video consultations, 92% were allergists and only 54% considered that their institution provided adequate conditions. The physicians of the INSPIRERS group used telephonic consultations as the main alternative to presential ones and 1/5 used video consultations. These results suggest the need to rethink clinical follow-up services for outpatients in the near future increasing the use of telemedicine, especially video consultations.

Allergen sensitization associates with worse lung function parameters.

Summary: Objective. To assess the association between the number of allergen sensitizations and lung function variables in individuals with airway symptoms. Methods. Retrospective study with all individuals who performed lung function and skin-prick tests at CUF-Porto (01/2011-06/2016). Six allergen groups were considered. % predicted Pre-Bronchodilator test (BD) and % change after BD were analysed for spirometry and plethysmography parameters. Results. A total of 1293 individuals were included, 54% (n = 698) adults and 69% (n = 891) with sensitization to ≥ 1 allergen group. % FEV1 was significantly higher and % change in FEV1 significantly lower in non-sensitized individuals. % sRaw was higher in polysensitized (vs non-sensitized). Conclusions. The presence of allergen sensitizations was significantly associated with worse key lung function parameters.

Opinions of patients with persistent asthma regarding the use of mobile applications for disease monitoring.

SUMMARY: Background.We assessed adherence to treatment and management needs of adults with persistent asthma and their interest in using apps for asthma management. Secondarily, we explored opinions of patients about an app to assess and improve adherence to treatment. Methods. A cross-sectional study was conducted with 40 adults with persistent asthma (49.9 ± 15.8 years) recruited at outpatient clinics from a district hospital. Participants answered a survey on sociodemographic, asthma control, treatment adherence and use of mobile devices, social networks and apps. Four patients participated in a prospective extension of the study, in which they were invited to use the InspirerMundi app. Results. 48 percent of the participants had at least greater-equal than 1 exacerbation in the previous year and 85 percent had uncontrolled asthma. Self-reported adherence to treatment showed that one in four participants had low adherence. At least daily, 55 percent of participants navigated on the internet with their smartphone-tablet, 35 percent used apps and 93 percent social networks. Nine (22 percent) participants had previously used health-fitness apps and 65 percent would like to use apps to improve inhaler adherence. Conclusions. Most participants had uncontrolled asthma, reported high adherence to treatment and were daily users of social networks and the internet. Only 1/4 used apps but 2/3 would like to use apps to support asthma management.

Heat stress response in slick vs normal-haired Criollo Limonero heifers in a tropical environment.

To assess the effect of hair type on the heat stress response, 20 Criollo Limonero heifers with slick (n = 11) or normal hair (n = 9) were studied. Under a high temperature-humidity index (THI) environment, heat stress response was assessed through physiological variables that included respiration rate (RR), heart rate (HR), ruminal frequency (RMF), rectal temperature (RT), saliva pH (SPH), and lymphocyte count (LC) in the morning (5:00 AM, 27.4 °C, 64% relative humidity, THI = 77) and afternoon (1:00 PM, 34.5 °C, 70% relative humidity, THI = 88). A case-control study using a split plot design was used. Data were analyzed using ANOVA (PROC MIXED SAS 2010) and a statistical model comprising the fixed effects of hair length, sampling hour, interaction of hair length by sampling hour, and the random effect of animal nested within hair type on physiological variables associated with heat stress response. Sampling hour influenced (P < 0.0001) RR, RT, and (P < 0.003) SPH. Hair length influenced RR (P < 0.01) and RT (P < 0.04) and tended to influence LC (P < 0.07). The interaction of sampling hour by hair influenced RR (P < 0.04), RT (P < 0.0002), and both SPH and LC (P < 0.05). During afternoon hours, slick-haired heifers had lower values for RR (81 ± 4.2 vs 102 ± 4.7 bpm; P < 0.01), RT (39.5 ± 0.1 vs 40.3 ± 0.1 C°; P < 0.002), and LC (60 ± 3.2 vs 72.3 ± 3.6; P < 0.09) than normal-haired heifers. In normal-haired heifers, SPH increased during afternoon compared to morning-hours (8.66 ± 0.1 vs 9.11 ± 0.1; P < 0.04). It was concluded that slick-coated heifers exhibited an enhanced capability to cope with heat stress compared to normal-haired heifers likely due to an enhanced capacity for heat dissipation.

The impact of head and neck radiotherapy on the dentine-enamel junction: a systematic review.

BACKGROUND: Radiotherapy is widely used in contemporary head and neck cancer treatment protocols. The ability of head and neck radiotherapy (HNRT) to cause direct radiogenic destruction to the teeth is one of the most controversial topics in the field of oral oncology. Therefore, this systematic review aimed to investigate ionising radiation as an independent factor for physical and chemical changes on the dentine-enamel junction (DEJ), a pivotal dental topography for the onset and progression of radiation-related caries (RRC) and enamel delamination. MATERIAL AND METHODS: Systematic searches were conducted on three databases: Scopus, MEDLINE (Via PubMed) and Embase (Elsevier). Laboratory studies evaluating the effects of simulated or in vivo HNRT on the DEJ were included. The GRADE tool adapted for in vitro studies was used to assess the methodological quality. RESULTS: Of the 154 initially selected studies, eight met the inclusion criteria, from which five studies were graded as high quality of evidence, two studies were graded as moderate quality and one as low quality. Two studies did not demonstrate DEJ alterations following HNRT while the other six articles described several organic and inorganic changes in the DEJ of irradiated teeth samples. These radiogenic events were mostly detected through micro and nanoindentation, Raman micro-spectroscopy, confocal microscopy, Western blotting and optical coherence tomography. CONCLUSIONS: HNRT may have a negative impact on the physical and chemical aspects of the DEJ, predisposing cancer patients to RRC and enamel delamination.

Submicroscopic Plasmodium infection during pregnancy is associated with reduced antibody levels to tetanus toxoid.

Submicroscopic Plasmodium infections in pregnancy are common in endemic areas, and it is important to understand the impact of these low-level infections. Asymptomatic, chronic infections are advantageous for parasite persistence, particularly in areas where the optimal eco-epidemiological conditions for parasite transmission fluctuate. In chronic infections, the persistence of the antigenic stimulus changes the expression of immune mediators and promotes constant immune regulation, including increases in regulatory T cell populations. These alterations of the immune system could compromise the response to routine vaccination. This study aimed to evaluate the effect of submicroscopic plasmodial infection with P. falciparum and P. vivax during pregnancy on the immune response to the tetanus toxoid vaccine in Colombian women. Expression of different cytokines and mediators of immune regulation and levels of anti-tetanus toxoid (TT) immunoglobulin (Ig)G were quantified in pregnant women with and without submicroscopic plasmodial infection. The anti-TT IgG levels were significantly lower in the infected group compared with the uninfected group. The expression of interferon (IFN)-γ, tumour necrosis factor (TNF) and forkhead box protein 3 (FoxP3) was significantly higher in the infected group, while the expression of cytotoxic T lymphocyte antigen 4 (CTLA-4) and transforming growth factor (TGF)-ß was lower in the group of infected. In conclusion, submicroscopic Plasmodium infection altered the development of the immune response to the TT vaccine in Colombian pregnant women. The impact of Plasmodium infections on the immune regulatory pathways warrants further exploration.

Acute kidney injury in HIV-infected patients: a critical review.

Acute kidney injury (AKI) is characterized by a rapid decline of renal function associated with worse outcomes. The purpose of the authors is to perform a critical review of the incidence, risk factors, pathogenesis and outcome of AKI in HIV-infected patients. Human immunodeficiency virus (HIV)-infected patients have an increased risk of developing AKI, to which contribute both HIV-dependent and HIV-independent factors as well as the nephrotoxicity of drugs used. The increased risk of AKI in HIV-infected patients and its negative impact on prognosis highlights the need for identification of patients at risk, creation of prevention strategies and management. HIV-infected patients have an increased risk of developing AKI, to which both HIV-dependent and HIV-independent factors contribute, as well as the nephrotoxicity of drugs used. The increased risk of AKI in HIV-infected patients and its negative impact on prognosis highlight the need for identification of patients at risk, creation of prevention strategies and management.

Probiotic effect of Bifidobacterium longum 51A and Weissella paramesenteroides WpK4 on gerbils infected with Giardia lamblia.

AIMS: The objective of this study was to assess the probiotic potential of genuine strains of Bifidobacterium longum 51A and Weissella paramesenteroides WpK4, in experimental giardiasis. METHODS AND RESULTS: The bacteria were administered orally to gerbils (Meriones unguiculatus) 10 days before oral infection with trophozoites of Giardia lamblia. After 7 days of infection, the animals were euthanized and portions of the duodenum were processed for histopathologic, histochemical and morphometric assessment. The height of the intestinal crypts and crypt/villi ratio were higher in infected groups (P < 0·05) than in noninfected groups. The area of mucus production was higher (P < 0·05) in infected animals pretreated with B. longum 51A than in other groups. The parasitic load of the animals that received both bacteria decreased significantly (P < 0·05) compared to the ones of the control group. CONCLUSIONS: Our results suggest a probiotic function of B. longum 51A and W. paramesenteroides WpK4 and may result in their use as a prophylactic and therapeutic alternative for promoting human and animal health. SIGNIFICANCE AND IMPACT OF THE STUDY: Bifidobacterium longum 51A and W. paramesenteroides WpK4 may constitute prophylactic alternatives, reversing the emergence of side effects and resistance observed in the conventional treatment of giardiasis.

Simultaneously elevated FeNO and blood eosinophils relate to asthma morbidity in asthmatics from NHANES 2007-12.

BACKGROUND: Fraction of exhaled nitric oxide (FeNO) and blood eosinophil (B-Eos) count are biomarkers for type 2 inflammation. However, they signal different inflammatory pathways. Simultaneously elevated, they are related to more asthma events in a general population and among younger asthmatics. OBJECTIVE: To investigate if simultaneously elevated FeNO and B-Eos relate to asthma outcomes and lung function among subjects with asthma at a wide age span, and how different cut-offs for the markers affect these relations. METHOD: FeNO, B-Eos and forced expiratory volume in 1 second (FEV1 ) were assessed in 1419 subjects with asthma, aged 6-79 years old, from the National Health and Nutrition Examination Survey (NHANES) 2007-12. Elevated levels were defined as FeNO ≥20 p.p.b. for children <12 years and ≥25 p.p.b. for subjects ≥12 years and B-Eos count ≥300 cells/µL. Additional analyses were performed for the cut-offs FeNO >35/30 and >50/35 p.p.b., and for B-Eos ≥400 and ≥ 500 cells/µL, as well as for different age subgroups (6-17, 18-44, >44 years old). Asthma events during the past year were self-reported. RESULTS: Subjects with simultaneously elevated FeNO and B-Eos compared with normal levels of both markers had a higher adjusted odds ratio (aOR (95%CI)) for having FEV1 <80% of predicted (2.15 (1.28-3.59), wheeze disturbing sleep (1.88 (1.27, 2.78)) but did not differ regarding asthma attacks past year. Elevated B-Eos, but not FeNO, was related to higher aOR for asthma attack (1.57 (1.14, 2.18) or emergency room (ER) visit due to asthma (1.88 (1.33, 2.64) when elevated FeNO and elevated B-Eos were studied as independent predictors. CONCLUSION: Simultaneously elevated FeNO and B-Eos related to reduced lung function in asthmatics, wheezing symptoms, but not to a history of asthma attacks. Asthma attacks and ER-visit due to asthma were related to increased B-Eos levels.

Daily allergic multimorbidity in rhinitis using mobile technology: A novel concept of the MASK study.

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

Treatment of allergic rhinitis using mobile technology with real-world data: The MASK observational pilot study.

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

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.
