RESUMO

Background: Recent data about clinical features, triggers and management of anaphylaxis in Latin America is lacking. Objective: To provide updated and extended data on anaphylaxis in this region. Method: An online questionnaire was used, with 67 allergy units involved from 12 Latin-American countries and Spain. Among data recorded, demographic information, clinical features, severity, triggering agents, and treatment were received. Results: Eight hundred and seventeen anaphylactic reactions were recorded. No difference in severity, regardless of pre-existing allergy or asthma history was found. Drug induced anaphylaxis (DIA) was most frequent (40.6%), followed by food induced anaphylaxis (FIA) (32.9%) and venom induced anaphylaxis (VIA) (12%). FIA and VIA were more common in children-adolescents. Non-steroidal anti-inflammatory drugs (NSAIDs) and beta-lactam antibiotics (BLA) were the most frequent drugs involved. Milk (61.1% of FIA) and egg (15.4% of FIA) in children, and shellfish (25.5% of FIA), fresh fruits (14.2% of FIA), and fish (11.3% of FIA) in adults were the most common FIA triggers. Fire ants were the most frequent insect triggers, and they induced more severe reactions than triggers of FIA and DIA (p < 0.0001). Epinephrine was used in 43.8% of anaphylaxis episodes. After Emergency Department treatment, epinephrine was prescribed to 13% of patients. Conclusions: Drugs (NSAIDs and BLA), foods (milk and egg in children and shellfish, fruits and fish in adults) and fire ants were the most common inducers of anaphylaxis. Epinephrine was used in less than half of the episodes emphasizing the urgent need to improve dissemination and implementation of anaphylaxis guidelines.

RESUMO

Anaphylaxis, a potentially life-threatening reaction, is characterized by acute symptoms affecting various systems and requires immediate medical intervention. While the overall mortality rate is low, anaphylaxis induced by foods and drugs has seen an increase. Common triggers include foods, drugs, and Hymenoptera venom. Epidemiology varies by region and age, with a global incidence of 50-112 episodes per 100,000 people annually. Implicated foods vary by age and region, with peanuts and nuts being common triggers. Two mechanisms of anaphylaxis are recognized: IgE-mediated and non-IgE-mediated. Diagnosis is based on clinical criteria and serum tryptase levels. Treatment includes epinephrine, oxygen, and intravenous fluids. Exercise-induced food-dependent anaphylaxis is addressed, where exercise, combined with certain foods, triggers anaphylactic reactions. Proper understanding and management are crucial to mitigate risks.

La anafilaxia, una reacción potencialmente mortal, se caracteriza por la aparición aguda de síntomas que afectan diversos sistemas y requiere intervención médica inmediata. Aunque la tasa de mortalidad general es baja, la anafilaxia inducida por alimentos y fármacos ha experimentado un aumento. Los alimentos, fármacos y veneno de himenópteros son desencadenantes comunes. La epidemiología varía según la región y la edad, con una incidencia global de 50-112 episodios anuales por cada 100,000 personas. Los alimentos más implicados varían según la edad y la región, y los desencadenantes más comunes son cacahuetes y nueces. Se reconocen dos mecanismos de anafilaxia: mediado por IgE y no mediado por IgE. El diagnóstico se basa en criterios clínicos y niveles de triptasa sérica. El tratamiento incluye epinefrina, oxígeno y líquidos intravenosos. Se aborda la anafilaxia inducida por ejercicio dependiente de alimentos, donde el ejercicio, en combinación con ciertos alimentos, desencadena reacciones anafilácticas. La comprensión y el manejo adecuados son cruciales para mitigar riesgos.

RESUMO

Background: Allergic rhinitis (AR) affects up to 40% of the general population, there are large-scale multicenter studies that have described its characteristics and few studies have focused on studying patients with AR in Latin America (LA). Methodology: A cross-sectional, descriptive, multicenter study was carried out in four LA countries (Colombia, Argentina, Cuba and Peru). Patients diagnosed with AR between November 2017 and June 2020 were included. Sociodemographic and clinical data, sensitization profile and current treatment were collected in the Electronic Data Collection (BDClinic). Patients also filled out this questionnaires: Rhinitis Control Assessment Test (RCAT), Reflexive Total Nasal Symptom Score (rTNSS), Modified ARIA Criteria for AR Severity (mARIA) and ESPRINT-15. Risk of bias was examined by applying the STROBE checklist. Results: The study included 412 patients. Median age was 25 years (15-39). Two hundred and twenty four (54.3%) were women. Nasal obstruction was present in 303 (73.5%). Three hundred and thirty four (81%) had a persistent AR. One hundred and twenty one (31.3%) had associated asthma. The most frequently positive skin tests were: Dermatophagoides pteronyssinus in 365 (88.6%) and Dermatophagoides farinae in 331 (81.3%). Four hundred and eleven patients (99%) reported that AR affected their quality of life. The median score of ESPRINT-15 was 1.87 (0.93-2.93), The mean values of RCAT and rTNSS were 19.01 (±4.59) and 5.4 (±2.97) respectively. Two hundred and fifty (60%) were receiving only oral antihistamines. Physicians decided to start nasal corticosteroids in 296 (71.8%). Only seventy patients (16.9%) were receiving immunotherapy. Conclusion: These findings confirm that most of patients with AR in LA have a persistent disease with a negative impact on quality of life. Dust mites are the main sensitizers. These findings will allow to know the true impact of AR and can lead to a better disease management.

RESUMO

The International Classification of Diseases (ICD) provides a common language for use worldwide as a diagnostic and classification tool for epidemiology, clinical purposes and health management. Since its first edition, the ICD has maintained a framework distributing conditions according to topography, with the result that some complex conditions, such as allergies and hypersensitivity disorders (A/H) including anaphylaxis, have been poorly represented. The change in hierarchy in ICD-11 permitted the construction of the pioneer section addressed to A/H, which may result in more accurate mortality and morbidity statistics, including more accurate accounting for mortality due to anaphylaxis, strengthen classification, terminology and definitions. The ICD-11 was presented and adopted by the 72nd World Health Assembly in May 2019, and the implementation is ongoing worldwide. We here present the outcomes from an online survey undertaken to reach out the allergy community worldwide in order to peer review the terminology, classification and definitions of A/H introduced into ICD-11 and to support their global implementation. Data are presented here for 406 respondents from 74 countries. All of the subsections of the new A/H section of the ICD-11 had been considered with good accuracy by the majority of respondents. We believe that, in addition to help during the implementation phase, all the comments provided will help to improve the A/H classification and to increase awareness by different disciplines of what actions are needed to ensure more accurate epidemiological data and better clinical management of A/H patients.

RESUMO

Anaphylaxis is a severe allergic reaction with a rapid onset and it is potentially life-threatening. Its clinical manifestations are varied; they may affect the skin, the cardiovascular system, the respiratory system, and the digestive system, among others. The treatment of choice, which is an intra-muscular injection of epinephrine (adrenaline), must be applied promptly. Therefore, being prepared to recognize it properly is of crucial importance. The objective of this clinical practice guide is to improve the knowledge of health professionals about anaphylaxis and, consequently, to optimize the treatment and long-term management of this reaction. This guide is adapted to the peculiarities of Latin America; especially in matters regarding the treatment. The need to introduce epinephrine auto-injectors in countries that don't have them yet is highlighted.

La anafilaxia es una reacción alérgica grave de instauración rápida y potencialmente mortal. Sus manifestaciones clínicas son muy variadas, pudiendo afectar la piel, el sistema cardiovascular, el aparato respiratorio y el digestivo, entre otros. El tratamiento de elección, mediante la inyección intramuscular de adrenalina, debe ser precoz. Por lo anterior, es vital estar preparados para reconocerla adecuadamente. El objetivo de la presente guía de actuación clínica es mejorar el conocimiento de los profesionales sanitarios sobre anafilaxia y, consecuentemente, optimizar el tratamiento y manejo a largo plazo de esta entidad. La guía está adaptada a las peculiaridades de América Latina, especialmente en los aspectos relativos al tratamiento. Se destaca la necesidad de introducir los autoinyectores de adrenalina en los países que no dispongan de ellos.

RESUMO

Chronic urticaria (CU) has a widespread spectrum on causal or exacerbating factors, clinical manifestations, therapeutic response and quality of life affectation. Registries are useful tools in several real-life diagnosis and management approach.We aimed to evaluate the characteristics of CU patients living in Latin America through an original cross-sectional registry with data entered by regional allergologists. RESULTS: Three hundred patients were included, being 72% female, with median age of 36 years (1-85) and 20 months of CU median evolution time. The cause of CU was reported as unknown in 72% of them.Thirty-nine percent of suspected cases presented positive serology for Mycoplasma, positive autologous serum skin test (ASST) was reported in 47%, and occasional presence of thyroid or antinuclear autoantibodies and parasites. The impact of pruritus in their quality of life was moderate to severe in 60% of patients, with almost 3 out of four patients having partial or lack of urticaria control with anti-histamines. CONCLUSIONS: Our registry provides retrospective data on the real-life assistance of a large number of patients from the region. Continuous search for associated conditions and better treatment possibilities are needed, in order to control the significant impact on quality of life and the length of disease.

RESUMO

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.

MASK (Mobile Airways Sentinel Network) forma parte integral de un proyecto apoyado por la Unión Europea contra las enfermedades crónicas y enfocado al envejecimiento activo y saludable. Constituye la tercera fase de ARIA (Allergic Rhinitis and its Impact on Asthma), en la cual mediante una aplicación móvil en un dispositivo inteligente se intenta guiar al paciente en el control de su multimorbilidad, rinitis o conjuntivitis alérgicas o asma. La aplicación Diario de Alergia por MACVIA-ARIA es gratuita y está disponible para Android e iOS; en ella, los pacientes indican diariamente cuánto les molestan los síntomas a través de cinco pantallas con una escala visual análoga; recientemente se agregaron dos pantallas más (afectación del sueño). La aplicación también permite descargar los datos del "Diario de alergias" en la computadora del médico en el momento de la consulta a través de un código QR. En este artículo reseñamos el primer año de experiencia en España, México y Argentina, que utilizan la versión española.

RESUMO

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.

La mayoría de los pacientes con rinitis alérgica no recibe el manejo idóneo, sino que se automedica. MASK (Mobile Airways Sentinel Network) forma parte integral de un proyecto apoyado por la Unión Europea contra las enfermedades crónicas y enfocado al envejecimiento activo y saludable. Constituye la tercera fase de ARIA (Allergic Rhinitis and its Impact on Asthma), en la cual mediante una aplicación móvil en un dispositivo inteligente se intenta guiar al paciente en el control de su multimorbilidad, rinitis o conjuntivitis alérgicas o asma. La aplicación Diario de Alergia por MACVIA-ARIA es gratuita y está disponible para Android e iOS. Al descargarla al celular del paciente, a este se le piden datos de su perfil, patologías alérgicas y medicación; posteriormente, mediante una escala visual analógica se le invita a determinar el grado de afectación en nariz, ojos y bronquios y su influencia sobre su productividad laboral/escolar. Con los datos del Diario de Alergia se observa que existe un nuevo patrón de presentación: rinitis alérgica + conjuntivitis alérgica + asma, con mayor afectación, así como un alto nivel de automedicación: en general, el paciente toma medicación cuando presenta síntomas. La app se ha desplegado en 23 países, incluyendo varios países hispanohablantes.

RESUMO

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.

RESUMO

The Global Alliance against Chronic Respiratory Diseases (GARD) is a network of organizations coordinated by the World Health Organization. It is a voluntary alliance of national and international organizations, institutions and agencies with global scope that are committed with actions to improve access to prevention, care and essential medications. On its last annual meeting, celebrated in Brussels (Belgium) in September 2017, the need for actions and representation to be grouped by geographic regions was discussed. There are several successful programs regarding morbidity and mortality control of these diseases, and others that improve cost-benefit and quality of life. Thus, SLaai proposes to contribute to the diffusion and knowledge of chronic respiratory diseases magnitude and risk factors, to identify successful programs in Latin America in order for them to be replicated in the region and to generate strategic alliances for the strengthening of joint actions.

RESUMO

BACKGROUND: To date, few studies have focused on the clinical and allergic characteristics of asthma in the elderly, defined as asthma in people aged 60 or over. Thus, we propose to identify and study the clinical and allergic characteristics and comorbidities of patients with asthma among the elderly. METHODS: A retrospective, observational, descriptive study was developed in five clinics and hospitals in Argentina. Allergy Physicians analyzed their patients' medical records in 2014 and included those adults over the age of 60, who had been diagnosed with asthma according to the GINA guidelines. Clinical and allergic characteristics were analyzed. RESULTS: A total of 152 patients diagnosed with asthma, of whom 73% were women and 11% ex-smokers, were included in this study, with a mean age of 66 years. Only 10.5% of the participants had onset asthma past the age of 60. Regarding asthma severity, 74.3% were diagnosed with moderate persistent asthma, and 7.2% with severe persistent asthma. Eighty-four percent of the patients were treated with an inhaled corticosteroid (ICS) along with a long-acting ß 2-adrenergic agent (LABA). More than half of the patients had two or more comorbidities simultaneously. Allergic comorbidities were the most frequent comorbidities, followed by arterial hypertension. Among allergic comorbidities, most patients presented allergies at the nasal level. There were no significant differences between the subpopulations of patients with late-onset asthma (LOA) and asthma with onset before the age of 60, i.e. early onset asthma (EOA) in most of their clinical characteristics. However, it was observed that EOA accounted for a higher percentage of patients with nasal allergies as compared to LOA (71% vs 46%, p <  0.05).It is worth mentioning that almost half of the patients with LOA had allergies at the nasal level. CONCLUSION: These results may provide a better understanding of the clinical characteristics of asthma in the elderly in Argentina, thus, enabling the development of future therapeutic strategies and a better quality of life for our elderly asthma patients.

RESUMO

BACKGROUND: The Latin American Society of Allergy, Asthma, and Immunology (SLAAI) presents a document about the use of immunotherapy (IT) in Latin America, where administration patterns, indications and contraindications, effects on health, adverse events and socioeconomic impact are reviewed. OBJECTIVE: To review publications analyzing the use of IT in Latin America. METHODS: A literature review was carried out in order to identify works addressing IT in Latin America. This review was focused on practical scientific information available on IT in the region, and a parallel comparison was made with practices observed in the United States and European countries. RESULTS: Of the 21 Latin American countries included, only 9 had original articles meeting the selection criteria; a total of 82 articles were selected, most of them from Brazil and Mexico. Most widely used allergenic extracts in Latin America tropical and subtropical regions were those of mites and pollen. CONCLUSION: Although it is true that there are huge challenges for the future of IT in Latin America, studies on subcutaneous IT and sublingual IT are increasing, but most of them are retrospective and some have design bias, and more prospective studies are therefore required, using internationally validated scales for clinical evaluation.

Antecedentes: La Sociedad Latinoamericana de Alergia, Asma e Inmunología (SLAAI) presenta un documento acerca del uso de la inmunoterapia en Latinoamérica en el que se revisan los patrones de administración, indicaciones y contraindicaciones, efectos sobre la salud, eventos adversos e impacto socioeconómico. Objetivo: Revisar las publicaciones que abordaron el uso de la inmunoterapia en América Latina. Métodos: Se llevó a cabo revisión de la literatura para identificar trabajos enfocados en la inmunoterapia en América Latina. Esta revisión se enfocó en la información científica práctica disponible en la región sobre la inmunoterapia y se realizó un paralelo a lo observado en Estados Unidos y países europeos. Resultados: De los 21 países latinoamericanos incluidos, solo nueve tenían artículos originales que cumplían con los criterios de selección; en total se seleccionaron 82 artículos, la mayoría de Brasil y México. Los extractos alergénicos más utilizados fueron los de ácaros y polen en las regiones tropicales y subtropicales de América Latina. Conclusión: Si bien hay grandes desafíos para el futuro de la inmunoterapia en América Latina y los estudios de inmunoterapia subcutánea e inmunoterapia sublingual están aumentando, la mayoría son retrospectivos y algunos con sesgo de diseño, por lo que se requieren más trabajos prospectivos en los que se utilicen escalas validadas internacionalmente para la evaluación clínica.

RESUMO

The ARIA initiative was started during a World Health Organization workshop in 1999. The initial goals were to propose a new classification for allergic rhinitis, to promote the concept of multi-morbidity in asthma and rhinitis and to develop guidelines with stakeholders for world-wide use. ARIA is now focused on the implementation of emerging technologies for individualized and predictive medicine. MASK: MACVIA-Aria Sentinel Network uses mobile technology to develop care pathways that enable management by a multidisciplinary group or by patients themselves. An App for iOS and Android 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 interoperable tablet for health professionals. The escalation strategy uses recommendations of the European Innovation Partnership on Active and Healthy Ageing. The aim of ARIA's new approach is to provide an active and healthy life to people affected by rhinitis, regardless of age, gender or socioeconomic status, in order to reduce social and health inequalities caused by the disease.

La iniciativa ARIA (Rinitis Alérgica y su Impacto en el Asma) se inició durante un taller de la Organización Mundial de la Salud en 1999. Los objetivos iniciales fueron proponer una nueva clasificación de rinitis alérgica, promover el concepto de multimorbilidad en asma y rinitis y desarrollar guías con todas las partes interesadas para su en todos los países y poblaciones. ARIA, difundida e implementada en más de 70 naciones, ahora se centra en la implementación de tecnologías emergentes para la medicina individualizada y predictiva. MASK (MACVIA [Contre les Maladies Chroniques pour un Vieillissement Actif] Aria Sentinel Network) utiliza la tecnología móvil para desarrollar vías de atención que permitan el manejo de la rinitis y del asma por un grupo multidisciplinario o por los propios pacientes. Una aplicación (app) para iOS y Android está disponible en 20 países y 15 idiomas; utiliza una escala analógica visual para evaluar el control de los síntomas y la productividad del trabajo, así como un sistema de apoyo para las decisiones clínicas. Se asocia con una tabla interoperable (que permite intercambiar información) para médicos y otros profesionales de la salud. La estrategia de escalamiento utiliza las recomendaciones de la Asociación Europea de Innovación para el Envejecimiento Activo y Saludable. El objetivo del nuevo enfoque ARIA es proporcionar una vida activa y saludable a las personas afectadas por la rinitis, cualquiera que sea su edad, sexo o condición socioeconómica, con el fin de reducir las desigualdades sociales y de salud causadas por la enfermedad.

RESUMO

PURPOSE OF REVIEW: The review critically assesses the different phenotypes of angioedemas associated with NSAIDs. Angioedemas exacerbated or induced by NSAIDs have high morbidity and, when they affect the larynx, can lead to death by asphyxiation. RECENT FINDINGS: Angioedema can present as a manifestation of a syndrome such as anaphylaxis or it can be a separate entity, which comprises different forms that can be diagnosed based on specific criteria. NSAIDs are the drugs most used worldwide and they are also one of the leading causes of angioedema. SUMMARY: The manuscript addresses the pathophysiology and pharmacogenetics of angioedema, reviews its classification and assesses the diagnosis and management of angioedemas exacerbated and induced by NSAIDs.

RESUMO

PURPOSE OF REVIEW: Registries are useful to discover the applicability of data generated from randomized clinical trials (RCTs) into daily practice, and to search for real-life data usually not covered by them. RECENT FINDINGS: In allergy, registry research brought clues to important epidemiological and clinical problems hardly accessible with other methods. The increase in the asthma prevalence in Sweden in contrast with stabilization in Denmark; the association of the prevalence of asthma and environmental factors; the knowledge of existing rhinitis international guidelines, but the poorly complacence of some of their recommendations; the low epinephrine use in anaphylaxis and the difference among European and Latin American elicitors; the predominance of ß lactams or NSAIDs as drug hypersensitivity reactions inducers in different regions; the fact that most of the hereditary angioedema patients were receiving long-term prophylaxis with attenuated androgens; all the mentioned are clear examples of relevant and important data provided by current registries. SUMMARY: Registries in allergy enlighten knowledge in areas not covered by classical investigational methods. As the number and importance of registries is growing, its contribution to the knowledge and management of allergic diseases will increase in the near future.

RESUMO

Antibiotics are used extensively in the treatment of various infections. Consequently, they can be considered among the most important agents involved in adverse reactions to drugs, including both allergic and non-allergic drug hypersensitivity [J Allergy Clin Immunol 113:832-836, 2004]. Most studies published to date deal mainly with reactions to the beta-lactam group, and information on hypersensitivity to each of the other antimicrobial agents is scarce. The present document has been produced by the Special Committee on Drug Allergy of the World Allergy Organization to present the most relevant information on the incidence, clinical manifestations, diagnosis, possible mechanisms, and management of hypersensitivity reactions to non beta-lactam antimicrobials for use by practitioners worldwide.

RESUMO

Allergic rhinitis and asthma represent global problems of public health affecting all age groups; asthma and allergic rhinitis frequently coexist in the same patients. In Latin American prevalence of allergic rhinitis, although variable, is very high. Allergic rhinitis and its Impact on Asthma (ARIA) started during a workshop of the World Health Organization performed in 1999 and was published in 2001. ARIA proposed a new classification of allergic rhinitis in intermittent or persistent and mild or moderate-severe. This approach of classification reflects more nearly the impact of allergic rhinitis in patients. In its review of 2010 ARIA developed guidelines for diagnosis and treatment of allergic rhinitis and of clinical practices for management of comorbidities of allergic rhinitis and asthma based on GRADE (Grading of Recommendations, Development and Evaluation). ARIA has been spread and implemented in more than 50 countries. In Latin American an intense activity has been developed to spread these recommendations in almost all the countries of the region and it is important to record the obtained goals in the diffusion and implementation of ARIA, as well as to identify the unsatisfied needs from the clinical, research and implementation points of view. Final objective is to reinforce the priority that allergy and asthma should have, especially in children, in the programs of public health, as they have been prioritized in European Union in 2011.

La rinitis alérgica y el asma representan problemas globales de salud pública que afectan a todos los grupos etarios; el asma y la rinitis alérgica frecuentemente coexisten en los mismos pacientes. En América Latina la prevalencia de rinitis alérgica, aunque variable, es muy elevada. La iniciativa Rinitis Alérgica y su Impacto en Asma (globalmente conocida como ARIA, de su nombre en inglés Allergic Rhinitis and its Impact on Asthma) comenzó durante un taller de la Organización Mundial de la Salud (OMS) realizado en 1999 que se publicó en el año 2001. ARIA propuso una nueva clasificación de rinitis alérgica en intermitente o persistente y leve o moderada-severa. Este esquema de clasificación refleja más estrechamente el impacto de la rinitis alérgica en los pacientes. En su revisión de 2010, la guía ARIA desarrolló pautas para el diagnóstico y tratamiento de la rinitis alérgica y de prácticas clínicas para el manejo de las comorbilidades de la rinitis alérgica y el asma basadas en GRADE (Gradación de Recomendaciones, Desarrollo y Evaluación). ARIA se ha diseminado e implantado en más de 50 países. En América Latina se ha desarrollado una intensa actividad para diseminar estas recomendaciones en casi todos los países de la región y es importante llevar un registro de los logros obtenidos en la difusión e implantación de ARIA, además de identificar las necesidades insatisfechas desde el punto de vista clínico, de la investigación y de la implantación. El objetivo final es reforzar la prioridad que deben tener la alergia y el asma ­especialmente en niños­ en los programas de Salud Pública, tal como los priorizó la Unión Europea en 2011.
