Association and correlation of patient symptom perception and asthma control - a rapid literature review.

BACKGROUND: Several studies suggest that patients often under-estimate their asthma symptoms and over-estimate their level of asthma control, potentially putting them at risk of undertreatment with inhaled corticosteroids. OBJECTIVE: To determine the association and correlation between patient symptom perception and asthma control. METHODS: A rapid literature review comprising searches in MEDLINE, Embase and Cochrane Library identified English language articles published between 2011-2021 that included a statistical measure of the association or correlation between perceptions of symptoms and asthma control in patients with asthma (adults and/or children). [PROSPERO CRD42021230152]. The Joanna Briggs Institute (JBI) instrument was used for study quality appraisal. RESULTS: Of 22 identified studies, nine presented association data and 13 reported correlation analyses. Eight of nine association studies showed a discordance between patients perceived symptoms and level of asthma control or lung function; among these, patients more frequently overestimated their asthma control than they underestimated their asthma control. Of 10 studies reporting correlation coefficients, all reported a statistically significant correlation between increased symptoms and worse asthma control; however, the strength of the correlation was shown to be only weak or moderate in most studies (coefficients numerically ranged from 0.12 to 0.74). CONCLUSION: Many patients with asthma tend to overestimate their level of asthma control. Although more frequent or worse symptoms were shown to be statistically significantly correlated with worsening asthma control, there was wide variation in correlation strengths, most showing weak or moderate correlations. Research to further understand the reasons for patient symptom misperceptions are warranted.

Consensus on mild asthma management: results of a modified Delphi study.

OBJECTIVE: In order to understand the role of regular controller inhaled corticosteroids (ICS) versus as-needed ICS-formoterol in managing mild asthma, we performed a modified Delphi procedure. METHODS: Opinions from 16 respiratory experts to three surveys and during a virtual scientific workshop helped to develop final consensus statements (pre-defined as 70% agreement). RESULTS: Thirteen participants completed all rounds (response rate 81%). At the end of the procedure, there was final consensus on: regular daily ICS being the recommended treatment approach in mild persistent asthma, with better symptom control and robust long-term clinical data compared with as-needed ICS-formoterol (85%); to avoid noncompliance, frequently seen in mild asthma patients, regular ICS dosing should be accompanied by ongoing education on treatment adherence (100%); treatment aims should be targeting asthma control (92%) and reduction of exacerbation risk (85%). No consensus was reached on whether GINA or national guidelines most influence prescribing decisions. CONCLUSIONS: It is important to encourage patients to be adherent and to target both asthma control and exacerbation risk reduction. There is robust clinical evidence to support proactive regular dosing with ICS controller therapy plus as-needed short-acting beta-agonists for the management of patients with mild asthma.

Key factors associated with uncontrolled asthma - the Asthma Control in Latin America Study.

Objective: This study aimed to estimate asthma control at specialist treatment centers in four Latin American countries and assess factors influencing poor asthma control.Methods: Patients aged ≥12 years with an asthma diagnosis and asthma medication prescription, followed at outpatient specialist centers in Argentina, Chile, Colombia, and Mexico, were included. The study received all applicable ethical approvals. The Asthma Control Test (ACT) was used to classify patients as having controlled (ACT 20-25) or uncontrolled (ACT ≤19) asthma. Frequency and statistical tests were used to assess the association between hospital admissions/exacerbations/emergency department (ED) visits and uncontrolled asthma; multivariate logistic regression was used to assess the association of uncontrolled asthma with clinical/demographic variables.Results: A total of 594 patients were included. Overall controlled-asthma prevalence was 43.4% (95% confidence interval [CI]: 39.0, 47.4). Patients with uncontrolled asthma were more likely to be women (adjusted odds ratio [aOR]: 1.85; p = 0.003), non-white (aOR: 2.14; p < 0.001), obese (aOR: 1.71; p = 0.036), to have a low monthly family income (aOR: 1.75; p = 0.004), to have severe asthma (aOR:1.59; p = 0.26), and, compared with patients with controlled asthma, to have a higher likelihood of asthma exacerbations (34.5% vs. 15.9%; p < 0.001), hospital admissions (6.9% vs. 3.1%; p = 0.042), and ED visits (34.5% vs. 15.9%; p < 0.001) due to asthma.Conclusions: Even in specialist ambulatory services, fewer than half of patients were classified as having controlled asthma. The proportion of uncontrolled patients varied according to clinical and demographic variables.

Asthma severity in four countries of Latin America.

BACKGROUND: In Latin America, there is scarce information about severe asthma (SA) according to the ERS/ATS 2014 criteria. This study aimed to compare the demographic, socio, clinical characteristics, treatment, and use of healthcare resources between SA and non-severe asthma (NSA) patients in Argentina, Colombia, Chile and Mexico. METHODS: A cross-sectional study was conducted including 594 asthma patients from outpatient specialized sites. A descriptive analysis was performed comparing SA patients and NSA. Chi-square and Mann Whitney tests were used to assess associations between asthma severity and outcome variables. RESULTS: Using ERS/ATS 2014 criteria, 31.0% of the patients were identified as SA. SA patients were older at diagnosis (mean age 31.64 years vs 24.71 years, p < 0.001) and had higher proportion of uncontrolled asthma than the NSA patients (64.1% vs 53.2%, p < 0.001). SA patients reported a significantly higher proportion of both hospital admission and emergency room (ER) visits due to asthma in the last year, compared with NSA patients, 8.7% vs. 3.7% (p = 0.011) and 37.0% vs. 21.7% (p < 0.001), respectively. CONCLUSIONS: SA patients were older, had greater proportions in some comorbidities and experienced increased healthcare utilization. Also, our results showed that even in patients using the last steps of treatment (GINA step 4 or 5), there was still a higher proportion of uncontrolled disease.

Efficacy and safety of tiotropium in school-age children with moderate-to-severe symptomatic asthma: A systematic review.

BACKGROUND: Recently published data support the benefits and safety of the once-daily (OD) long-acting anticholinergic tiotropium bromide bronchodilator for the treatment of uncontrolled moderate-to-severe asthma in adults and adolescents. However, its role for the treatment of school-age asthmatics has not yet been clearly defined. The aim of this systematic review was to assess the efficacy and safety of tiotropium Respimat® in children aged 6-11 years with moderate-to-severe symptomatic asthma. METHODS: Randomized, placebo-controlled trials were included. Primary outcomes were peak forced expiratory volume in 1 s measured within 3 h post-dosing) [FEV1 (0-3 h) ] and trough FEV1 measured at the end of the dosing interval. RESULTS: Three studies (more than 900 patients) were selected. Tiotropium was associated with significant improvements in FEV1 peak (mean change from baseline) by 102 mL (P<.0001) and trough by 82 mL (P<.0001) compared with placebo. Tiotropium 5 µg dose presented a trend (statistically non-significant) toward a greater bronchodilation in comparison with 2.5 µg dose. Tiotropium significantly increased the rate of the Asthma Control Questionnaire (ACQ-7) responders compared with placebo (82.2% vs 75.4%, number needed to treat for benefit [NNTB]=15) and significantly decreased the number of patients with at least one exacerbation in comparison with placebo (29.1% vs. 39.8%, with a NNTB of 10). There were no significant differences in rescue medication use, withdrawals, and adverse events. CONCLUSIONS: OD tiotropium Respimat® is efficacious and well tolerated as an add-on to inhaled corticosteroids plus one or more controller medications in school-age symptomatic asthmatics.

A systematic review with meta-analysis of fluticasone furoate/vilanterol combination for the treatment of stable COPD.

BACKGROUND: Current guidelines recommend the use of inhaled corticosteroids/long-acting beta2-agonists as first-line therapy for COPD patients at risk for acute exacerbations and/or severe airflow limitation. This systematic review assesses available evidence on the efficacy and safety of fluticasone furoate/vilanterol (FF/VI) combination versus each alone, for the treatment of patients with severe to very severe stable COPD. METHODS: Randomized, placebo-controlled trials of >8 weeks of duration were included. Primary end points were pulmonary function, COPD exacerbations and serious adverse events. FF/VI was compared with its mono-components. RESULTS: Five reports with six trials (n = 15,515 patients) met the entry criteria. FF/VI was associated with significant increases in trough FEV1 compared with vilanterol (VI) and fluticasone furoate (FF) (45 mL and 90 mL respectively). FF/VI significantly reduced the number of subjects with at least one moderate to severe exacerbation compared with VI (number needed to treat for benefit [NNTB] = 21) and with FF (NNTB = 26). There were no statistical differences in the rates of serious adverse events, cardiac events and all-cause mortality. On the contrary, FF/VI showed a significant 52% increase in the rate of pneumonia compared with VI monotherapy (5.3% vs. 3.5%). However, there was no difference in the rate of pneumonia when FF/VI was compared with FF alone. CONCLUSIONS: FF/VI combination was associated with a decrease of the rate of COPD exacerbations, without affecting mortality or cardiovascular outcomes in patients with moderate to severe stable COPD. Also, the use of FF was associated with an increased risk of pneumonia.

Systematic review on the use of omalizumab for the treatment of asthmatic children and adolescents.

BACKGROUND: There are less data on omalizumab treatment in pediatric asthma than in adult population. Thus, to establish the efficacy and safety of subcutaneous omalizumab as an add-on therapy, a systematic review of placebo-controlled studies was performed. METHODS: Primary outcome was the frequency of asthma exacerbations. Secondary outcomes included spirometric measures, rescue medication use, asthma symptoms, health-related quality of life, and adverse events. RESULTS: Three randomized controlled trials (1381 participants) fulfilled the selection criteria. During the stable phase, omalizumab decreased the number of patients with at least one significant asthma exacerbation (26.7% vs. 40.6%, NNTB = 7, 95% CI, 5, 11). The predefined post hoc subgroup analysis showed that duration of treatment did not influence this result. During the steroid reduction phase, omalizumab reduced the number of patients with at least one exacerbation (RR = 0.48, 95% CI, 0.38, 0.61; NNTB = 6, 95% CI, 4, 8) and also the mean number of asthma exacerbations per patient (MD = -0.44, 95% CI, -0.72, -0.17) when compared to placebo. The frequency of serious adverse events was similar between omalizumab (5.2%) and placebo (5.6%), and there were no evidence of increased risk of hypersensitivity reactions, nor malignant neoplasms. CONCLUSIONS: Data indicate that the efficacy of an add-on omalizumab in patients with moderate-to-severe allergic asthma uncontrolled with recommended inhaled steroid treatment is accompanied by an acceptable safety profile.

Assessment of acute asthma severity in the ED: are heart and respiratory rates relevant?

BACKGROUND: Assessment of acute asthma severity in the emergency department (ED) determines the appropriate initial therapy. The aim of this study was to evaluate the usefulness of heart and respiratory rates as determinants of severity of asthma exacerbations. METHODS: It was a pooled analysis of individual patient data from different controlled clinical trials performed over a 9-year period. The sample was characterized by patients with a diagnosis of asthma, age 18 to 50 years, and a forced expiratory volume in the first second (FEV1) or a peak expiratory flow less than or equal to 50% of predicted at ED presentation. RESULTS: One thousand one hundred ninety-two severe acute asthmatics (age 33.9 ± 10.3 years and FEV1 = 27.4% ± 9.7%) were enrolled. Two-thirds of patients were categorized as having severe acute asthma (FEV1, 31%-50% of predicted) and the remaining third as life-threatening asthma (FEV1, ≤30% of predicted). There were no relationships between the intensity of airway obstruction as measured by the FEV1 and the degree of tachycardia (r = 0.05, P > .1) or tachypnea (r = 0.06, P > .1). Only 22% and 19% of the patients, respectively, met the heart rate and respiratory rate requirements for acute severe asthma (≥120/min and ≥25/min, respectively). In contrast to FEV1 and arterial oxygen saturation, baseline heart and respiratory rates did not predict admissions of patients at the end of treatment. CONCLUSIONS: This pooled analysis suggests a poor performance of heart and respiratory rates as determinants of acute asthma severity in the ED.

[Argentine guidelines for urticaria and angioedema]. / Guía argentina de urticaria y angioedema.

This interdisciplinary paper summarizes the news in the diagnosis and treatment of chronic urticaria (CU), and provides concepts, definitions and evidence-based suggestions for its management. Urticaria occurs in at least 20% of the population at some point in their lives. Acute urticaria (less than 6 weeks' duration), differs from CU in its etiology, but the onset of this disease is always acute. CU may occur as spontaneous (SCU) or induced (ICU). The diagnosis is simple, although a careful evaluation is necessary for differential diagnosis. ICU's diagnosis is mainly clinical, even if provocation tests can be useful. Supplementary studies should be limited and based on the clinical suspicion. Treatment may be divided into three approaches: avoidance, elimination or treatment of the cause, and pharmacological treatment. Recently treatment has been modified with the use of second-generation antihistamines as first-line and increased doses of nonsedating H1 antihistamines, up to 4 times, as second line. Antihistamines are essential to treat CU; however, 40% of patients do not achieve good control despite increased doses and require additional treatment. The most recent evidence indicates a group of drugs to be used as third line in these cases, to improve quality of life and to limit toxicity from frequent or chronic use of systemic steroids. Only 3 drugs are recommended as third line: omalizumab, cyclosporin A or anti-leukotrienes.

Exploring Clinical Remission in Moderate Asthma - Perspectives from Asia, the Middle East, and South America.

INTRODUCTION: Clinical remission is a relatively new concept in asthma but recent research initiatives suggest it could be an ambitious and achievable therapeutic target for patients with asthma. METHODS: In this modified Delphi study (comprising two online surveys, completed either side of a virtual scientific workshop), the opinions of a panel of respiratory physicians were evaluated to summarize perspective statements on key therapeutic outcomes and criteria for on-treatment clinical remission in patients with moderate asthma. An agreement threshold was pre-defined as agreement by ≥ 75% of participants. RESULTS: Surveys 1 and 2 were completed by 20 and 18 participants, respectively. Most participants (95%) agreed with the concept of clinical remission in moderate asthma and that this should be a desirable treatment goal (90%). Based on a composite measure of 4-6 desirable therapeutic outcomes, current understanding of clinical remission was considered as 12 months with no exacerbations, no oral corticosteroids, no daytime or night-time asthma symptoms (Asthma Control Test score ≥ 20 or Asthma Control Questionnaire score ≤ 0.75), stable lung function, and no treatment-related adverse events. No agreement was reached on the role of relievers in defining therapeutic outcomes or on the wider use of biomarkers and airway hyperresponsiveness for defining asthma remission in clinical practice. CONCLUSIONS: In line with recent consensus statements from the United States and Europe, there was a high level of agreement on the elements of clinical remission among a panel of respiratory physicians from Asia, the Middle East, and South America. Extension of the concept of clinical remission to patients with moderate asthma was considered aligned with the potential of clinical remission as a goal of therapy.

[Poorly controlled asthma: diagnosis and therapeutics in children and adolescents]. / Asma de difícil control en niños y adolescentes. Estrategias diagnóstico-terapéuticas.

Asthma is one of the most common chronic diseases in children. While most children with asthma respond to low doses of inhaled corticosteroids and /or leukotriene receptor antagonists, some of them remain symptomatic regardless of any therapeutic effort, showing a high morbidity and even mortality. While most of the patients control symptoms adequately, there is a large group with severe symptoms of the disease and difficult to control. The aim of this review is to discuss the clinical aspects, diagnosis and treatment of poorly controlled asthma in children and adolescents and its implications in daily clinical practice.

Ciclesonide, a hypotonic intranasal corticosteroid.

Intranasal corticosteroids (INCSs) are established as the first-line treatment of moderate to severe allergic rhinitis (AR) in both adults and children. Compared with other nasal allergy medications, INCSs are the most effective at providing symptom relief and increasing quality of life. Ciclesonide nasal spray is the most recently approved INCS. The formulation of ciclesonide does not contain benzylalkonium chloride or phenyl ethyl alcohol, excipients that have been associated with reduced mucociliary transport, and unpleasant sensory perceptions. Additionally, ciclesonide has been formulated in a hypotonic suspension that has been shown to optimize intranasal absorption and it has a lower volume of spray compared with most other INCS products. Systemic exposure to ciclesonide and its active metabolite desisobutyryl-ciclesonide is low after intranasal administration. High protein binding ( approximately 99%) and rapid first-pass clearance further reduce systemic exposure to the drug. Studies up to 1 year have shown that intranasal ciclesonide does not cause cortisol suppression as monotherapy and does not have an additive effect on the hypothalamic-pituitary-adrenal axis function when administered in combination with inhaled corticosteroids. The efficacy of ciclesonide, 200 microg/day, has been shown in pediatric, adolescent, and adult patients with moderate to severe seasonal AR and perennial AR treated for up to 1 year. Additionally, environmental exposure unit studies have established an onset of action as early as 1 hour after administration. Ciclesonide nasal spray has also been shown to have an acceptable safety profile in patients with AR as young as 2 years of age. Thus, intranasal ciclesonide appears to provide an additional effective treatment option for patients with AR.

Nasal allergies in the Latin American population: results from the Allergies in Latin America survey.

Allergies in Latin America is the first cross-national survey that describes the symptoms, impact, and treatment of nasal allergies (NAs) in individuals >or=4 years old in Latin America (LA). In total, 22,012 households across the Latin American countries of Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Peru, and Venezuela were screened for children, adolescents, and adults with a diagnosis of NA and either symptoms or treatment in the past 12 months. A total of 1088 adults and 457 children and adolescents were included and the sample was probability based to ensure valid statistical inference to the population. Approximately 7% of the LA population was diagnosed with NAs with two of three respondents stating that their allergies were seasonal or intermittent in nature. A general practice physician or otolaryngologist diagnosed the majority of individuals surveyed. Nasal congestion was the most common and bothersome symptom of NAs. Sufferers indicated that their symptoms affected productivity and sleep and had a negative impact on quality of life. Two-thirds of patients reported taking some type of medication for their NAs, with a roughly equal percentage of patients reporting taking over-the-counter versus prescription medications. Changing medications was most commonly done in those reporting inadequate efficacy. The most common reasons cited for dissatisfaction with current medications were related to inadequate effectiveness, effectiveness wearing off with chronic use, failure to provide 24-hour relief, and bothersome side effects (e.g., unpleasant taste and retrograde drainage into the esophagus). Findings from this cross-national survey on NAs have confirmed a high prevalence of physician-diagnosed NAs and a considerable negative impact on daily quality of life and work productivity as well as substantial disease management challenges in LA. Through identification of disease impact on the LA population and further defining treatment gaps, clinicians in LA may better understand and treat NAs, thus leading to improvements in overall patient satisfaction and quality of life.

[Environmental intervention in respiratory disease]. / Intervención ambiental en las enfermedades respiratorias.

In recent years there has been a significant increase in the prevalence of allergic diseases despite advances in the understanding of the pathogenesis, the dissemination of guidelines for its management and the emergence of new drugs. The reasons for this increase are not fully established, but it is suggested that multiple environmental factors may be involved. Inhaled air contains numerous harmful agents in addition to environmental allergens. The main immediate respiratory clinical expression after inhaling this contaminated air is asthma and rhinitis. The activity of human beings has altered the outdoor environment by the emission of multiple pollutants and has produced an increasing climate change. It also has a notable impact on the development of respiratory pathology and the modification of air quality. The bibliography on the subject of environmental control is very broad and sometimes difficult to interpret. In order to be able to make precise, valid and simple indications for patients to accomplish with, four scientific societies of the Argentine Republic that deal with this type of diseases, have elaborated a document that contains information of easy access to all medical personal involved in the treatment of patients with asthma and / or rhinitis, that provides practical measures for the patients and the different public health systems about unmet needs in this complex issue.

En los últimos años hubo un aumento significativo en la prevalencia de las enfermedades alérgicas pese a los avances en la comprensión de la patogénesis, la divulgación de guías para su control y tratamiento y la aparición de nuevos fármacos. La razón para este aumento no está totalmente establecida, pero se considera que múltiples factores ambientales podrían estar involucrados en ello. El aire inspirado contiene numerosos agentes nocivos además de alérgenos ambientales; el asma y la rinitis alérgica son las principales expresiones clínicas respiratorias inmediatas posteriores a su inhalación. En la antropósfera, el entorno de la superficie terrestre habitada por los humanos, se han alterado los equilibrios naturales por la emisión de múltiples sustancias y se ha producido un creciente cambio climático. Este fenómeno global influye en la calidad del aire y consecuentemente en el desarrollo de enfermedades respiratorias. Dado que la bibliografía sobre el tema del control ambiental es muy amplia, y en ocasiones difícil de interpretar para poder realizar indicaciones precisas, válidas y sencillas de cumplir por parte de los pacientes, cuatro sociedades científicas de la República Argentina, dedicadas a este tipo de enfermedades, elaboraron un documento con información de fácil acceso a todo profesional médico que trate asma y/o rinitis, que expone medidas prácticas para los enfermos y alerta a los distintos actores involucrados en la salud pública acerca de las necesidades insatisfechas en este tema tan complejo, a fin de poder elaborar una agenda para su posible resolución.

[MASK (Mobile Airways Sentinel Network). ARIA's comprehensive solution for mobile app for the multimorbidity of allergic rhinitis and asthma]. / MASK (Mobile Airways Sentinel Network). La solución integral de ARIA por app móvil para la multimorbilidad de rinitis alérgica y asma.

The vast majority of patients with allergic rhinitis (AR) do not receive the proper management which is recommended by the guidelines, but they frequently self-medicate. MASK (Mobile Airways Sentinel Network) is an integral part of a project that is supported by the European Union against chronic diseases and focused on active and healthy aging. MASK represents the third phase of ARIA (Allergic Rhinitis and its Impact on Asthma), in which, by using a mobile application in a smart device, the objective is to guide the patient in the control of his/her multi-morbidity, AR and/or allergic conjunctivitis (AC) and/or asthma. The mobile app Allergy Diary by MACVIA-ARIA is free and it is available for both Android and iOS platforms. After it is downloaded to the patient's cell phone, it first requests some information about the patient's profile, allergic pathologies and medication; afterwards, through a visual analog scale, the patient is invited to determine the degree of affectation in the nose, eyes, and bronchi, and its influence on their productivity at work / school. After analyzing the data generated by filling the Allergy Diary, it became clear there is a new clinical entity: allergic rhinitis+ allergic conjunctivitis +asthma, with greater effect; in addition to a high level of self-medication: in general, the patient takes medication on days when symptoms are present. The app has already been deployed in 23 countries, including several Spanish-speaking countries.

[Executive Summary of ARIA 2019: Integrated care pathways for allergic rhinitis in Argentina, Spain and Mexico]. / Resumen ejecutivo de ARIA 2019: Vías integradas de atención para la rinitis alérgica en Argentina, España y México.

The health and economic impact of allergic diseases are increasing rapidly, and changes in management strategies are required. Its influence reduces the capacity of work and school performance by at least a third. The ICPs of the airways (integrated care pathways for respiratory diseases) are structured multidisciplinary healthcare plans, promoting the recommendations of the guidelines in local protocols and their application to clinical practice. This document presents an executive summary for Argentina, Mexico, and Spain. Next-generation ARIA guidelines are being developed for the pharmacological treatment of allergic rhinitis (AR), using the GRADE-based guidelines for AR, tested with real-life evidence provided by mobile technology with visual analogue scales. It is concluded that in the AR treatment, H1-antihistamines are less effective than intranasal corticosteroids (INCS), in severe AR the INCS represent the first line of treatment, and intranasal combination INCS + anti-H1 is more effective than monotherapy. However, according to the MASK real-life observational study, patients have poor adherence to treatment and often self-medicate, according to their needs.

El impacto sanitario y económico de las enfermedades alérgicas está aumentando rápidamente y se necesitan cambios en las estrategias para su manejo. Su influencia reduce al menos en un tercio la capacidad de desempeño laboral y escolar. Los ICP (Vías Integradas de Atención) de las enfermedades de las vías respiratorias son planes de atención estructurados y multidisciplinarios, que promueven las recomendaciones de las guías en protocolos locales y su aplicación a la práctica clínica. En este documento se presenta un resumen ejecutivo para Argentina, México y España. Se desarrollan las guías ARIA de próxima generación para el tratamiento farmacológico de la rinitis alérgica (RA) utilizando las pautas basadas en GRADE para RA, probadas con evidencia de la vida real proporcionada por tecnología móvil basada en escalas visuales analógicas. Se concluye que en el tratamiento de la RA, los antihistamínicos anti-H1 son menos efectivos que los corticoides intranasales (CINS), que en la rinitis gravelos CINS representan la primera línea de tratamiento, y que la combinación intranasal de CINS + anti-H1 es más eficaz que la monoterapia. Sin embargo, según el estudio MASK observacional en vida real, los pacientes tienen pobre adherencia al tratamiento y frecuentemente se automedican de acuerdo con sus necesidades.

[MASK (Mobile Airways Sentinel Network), a mobile App with ARIA's comprehensive solution in Spanish-speaking countries]. / MASK (Mobile Airways Sentinel Network), una app móvil con la solución integral de ARIA en países de habla hispana.

Although there are high quality clinical guidelines about allergic rhinitis, many patients receive deficient treatment, partly due to the high level of self-medication. MASK (Mobile Airways Sentinel Network) is an integral part of a project against chronic diseases which it is focused on active and healthy aging and is supported by the European Union. It forms the third phase of ARIA (Allergic Rhinitis and its Impact on Asthma) in which, through a mobile app on a smart device, the purpose is to guide patients in the control of their multimorbidity, allergic rhinitis or conjunctivitis, or asthma. The "Allergy Diary" app by MACVIA-ARIA is free and it is available for Android and iOS; on it, patients indicate how unpleasant the symptoms are on a daily basis through five screens with an analogous visual scale; two more screens were recently added (sleep affectation). With the app, it is also possible to download the information of the "Allergy Diary" on the physician's computer through a QR code at the moment of the medical consultation. In this article, we review the first year of experience in Spain, Mexico and Argentina, where the Spanish version is used.

Prevalence and Features of Asthma in Young Adults in Urban Areas of Argentina. / Prevalencia y características clínicas del asma en adultos jóvenes en zonas urbanas de Argentina.

OBJECTIVE: To investigate the burden of asthma in a young adult population in urban areas of Argentina. DESIGN: A nationwide telephone survey in subjects aged 20-44 years was performed in urban areas in Argentina. The European Community Respiratory Health Survey questionnaire was used. Asthma was defined as an exacerbation in the last year or use of asthma medications. RESULTS: In total, 1,521 subjects responded (62.4% females, mean age 33 years), of whom 91 were classified as asthmatics (5.9%, 95% CI 4.7-7.1). Prevalence adjusted for age, sex and education level was 6.4% (95% CI 5.1-7.7). Wheezing was reported by 13.9% (95% CI 15.6-12.2) and a diagnosis of asthma by 9.5% (95% CI 8.0-11.0). Among individuals with a diagnosis of asthma (n=154), 71.3% had undergone spirometry. Among those treated (n=77), 51.9% used medications daily and 46.8% as a rescue measure. Of those reporting an exacerbation in the last year (n=60), 55% had attended an emergency department and 23% were admitted. Asthma was associated with rhinitis (OR 11.1, 95% CI 6.2-19.9) and family history (OR 3.6, 95% CI 2.3-5.5). CONCLUSION: Asthma prevalence in young adults in Argentina is similar to Europe. Although attacks and admissions were common, regular use of medications was reported by half of those treated. These results may be useful for other Latin American countries.
