RESUMEN

BACKGROUND: There was a need for a solid asthma guideline in Mexico to update and unify asthma management. Because high-quality asthma guidelines exist worldwide, in which the latest evidence on asthma management is summarized, the ADAPTE approach allows for the development of a national asthma guideline based on evidence from already existing guidelines, adapted to national needs. OBJECTIVE: To fuse evidence from the best asthma guidelines and adapt it to local needs with the ADAPTE approach. METHODS: The Appraisal of Guidelines for Research and Evaluation (AGREE) II asthma guidelines were evaluated by a core group to select 3 primary guidelines. For each step of asthma management, clinical questions were formulated and replied according to (1) evidence in the primary guidelines, (2) safety, (3) Cost, and (4) patient preference. The Guidelines Development Group, composed of a broad range of experts from medical specialties, primary care physicians, and methodologists, adjusted the draft questions and replies in several rounds of a Delphi process and 3 face-to-face meetings, taking into account the reality of the situation in Mexico. We present the results of the pediatric asthma treatment part. RESULTS: Selected primary guidelines are from the British Thoracic Society and Scottish Intercollegiate Guidelines Network (BTS/SIGN), Global Initiative for Asthma (GINA), and Spanish Guidelines on the Management of Asthma (GEMA) 2015, with 2016 updates. Recommendations or suggestions were made for asthma treatment in Mexico. In this article, the detailed analysis of the evidence present in the BTS/SIGN, GINA, and GEMA sections on the (non) pharmacologic treatment of pediatric asthma, education, and devices are presented for 2 age groups: children 5 years or younger and children 6 to 11 years old with asthma. CONCLUSION: For the pediatric treatment and patient education sections, applying the AGREE II and Delphi methods is useful to develop a scientifically sustained document, adjusted to the Mexican situation, as is the Mexican Guideline on Asthma.

RESUMEN

BACKGROUND: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice. In other parts of the world, extracts from both regions and local ones are commercialized, as in Mexico. Here, local experts developed a national AIT guideline (GUIMIT 2019) searching for compromises between both schools. METHODS: Using ADAPTE methodology for transculturizing guidelines and AGREE-II for evaluating guideline quality, GUIMIT selected 3 high-quality Main Reference Guidelines (MRGs): the European Academy of Allergy, Asthma and Immunology (EAACI) guideines, the S2k guideline of various German-speaking medical societies (2014), and the US Practice Parameters on Allergen Immunotherapy 2011. We formulated clinical questions and based responses on the fused evidence available in the MRGs, combined with local possibilities, patient's preference, and costs. We came across several issues on which the MRGs disagreed. These are presented here along with arguments of GUIMIT members to resolve them. GUIMIT (for a complete English version, Supplementary data) concluded the following. RESULTS: Related to the diagnosis of IgE-mediated respiratory allergy, apart from skin prick testing complementary tests (challenges, in vitro testing and molecular such as species-specific allergens) might be useful in selected cases to inform AIT composition. AIT is indicated in allergic rhinitis and suggested in allergic asthma (once controlled) and IgE-mediated atopic dermatitis. Concerning the correct subcutaneous AIT dose for compounding vials according to the US school: dosing tables and formula are given; up to 4 non-related allergens can be mixed, refraining from mixing high with low protease extracts. When using European extracts: the manufacturer's indications should be followed; in multi-allergic patients 2 simultaneous injections can be given (100% consensus); mixing is discouraged. In Mexico only allergoid tablets are available; based on doses used in all sublingual immunotherapy (SLIT) publications referenced in MRGs, GUIMIT suggests a probable effective dose related to subcutaneous immunotherapy (SCIT) might be: 50-200% of the monthly SCIT dose given daily, maximum mixing 4 allergens. Also, a table with practical suggestions on non-evidence-existing issues, developed with a simplified Delphi method, is added. Finally, dissemination and implementation of guidelines is briefly discussed, explaining how we used online tools for this in Mexico. CONCLUSIONS: Countries where European and American AIT extracts are available should adjust AIT according to which school is followed.

RESUMEN

BACKGROUND: In Mexico, allergen immunotherapy (AIT) and immunotherapy with hymenoptera venom (VIT) is traditionally practiced combining aspects of the European and American school. In addition, both types of extracts (European and American) are commercially available in Mexico. Moreover, for an adequate AIT/VIT a timely diagnosis is crucial. Therefore, there is a need for a widely accepted, up-to-date national immunotherapy guideline that covers diagnostic issues, indications, dosage, mechanisms, adverse effects and future expectations of AIT (GUIMIT 2019). METHOD: With nationwide groups of allergists participating, including delegates from postgraduate training-programs in Allergy/Immunology-forming, the guideline document was developed according to the ADAPTE methodology: the immunotherapy guidelines from European Academy of Allergy and Clinical Immunology, German Society for Allergology and Clinical Immunology, The American Academy of Allergy, Asthma and Immunology and American College of Allergy, Asthma, and Immunology were selected as mother guidelines, as they received the highest AGREE-II score among international guidelines available; their evidence conforms the scientific basis for this document. RESULTS: GUIMIT emanates strong or weak (suggestions) recommendations about practical issues directly related to in vivo or in vitro diagnosis of IgE mediated allergic diseases and the preparation and application of AIT/VIT and its adverse effects. GUIMIT finishes with a perspective on AIT modalities for the future. All the statements were discussed and voted on until > 80 % consensus was reached. CONCLUSIONS: A wide and diverse group of AIT/VIT experts issued transculturized, evidence-based recommendations and reached consensus that might improve and standardize AIT practice in Mexico.


Antecedentes: En México, la inmunoterapia con alérgenos (ITA) y con veneno de himenópteros (VIT) se practica tradicionalmente combinando criterios de las escuelas europea y estadounidense; los dos tipos de extractos están comercialmente disponibles en México. Para una ITA adecuada es crucial un diagnóstico oportuno. Objetivo: Presentar GUIMIT 2019, Guía Mexicana de Inmunoterapia 2019, de base amplia, actualizada, que abarca temas de diagnóstico, indicaciones, dosificación, mecanismos, efectos adversos de la ITA y expectativas con esta modalidad de tratamiento. Método: Con la participación de múltiples grupos mexicanos de alergólogos, que incluían los centros formadores universitarios en alergia e inmunología, se desarrolló el documento de la guía según la metodología ADAPTE. Las guías de inmunoterapia de la European Academy of Allergy and Clinical Immunology, The American Academy of Allergy, Asthma and Immunology, German Society for Allergology and Clinical Immunology y del American College of Allergy, Asthma, and Immunology se seleccionaron como guías fuente, ya que recibieron la puntuación AGREE-II más alta entre las guías internacionales disponibles; su evidencia conforma la base científica de GUIMIT 2019. Resultados: En GUIMIT 2019 se emiten recomendaciones fuertes o débiles (sugerencias) acerca de temas directamente relacionados con el diagnóstico in vivo o in vitro de las enfermedades alérgicas mediadas por IgE, la preparación y aplicación de ITA o VIT y sus efectos adversos; se incluye la revisión de las modalidades de ITA para el futuro. Todos los argumentos que se exponen fueron discutidos y votados con > 80 % de aprobación. Conclusión: Un grupo amplio y diverso de expertos en ITA y VIT emitió recomendaciones transculturizadas basadas en evidencia, que alcanzaron consenso; con ellas se pretende mejorar y homologar la práctica de la inmunoterapia en México.

RESUMEN

BACKGROUND: The need for a national guideline, with a broad basis among specialists and primary care physicians was felt in Mexico, to try unifying asthma management. As several high-quality asthma guidelines exist worldwide, it was decided to select the best three for transculturation. METHODS: Following the internationally recommended methodology for guideline transculturation, ADAPTE, a literature search for asthma guidelines, published 1-1-2007 through 31-12-2015 was conducted. AGREE-II evaluations yielded 3/40 most suitable for transculturation. Their compound evidence was fused with local reality, patient preference, cost and safety considerations to draft the guideline document. Subsequently, this was adjusted by physicians from 12 national medical societies in several rounds of a Delphi process and 3 face-to-face meetings to reach the final version. RESULTS: Evidence was fused from British Thoracic Society Asthma Guideline 2014, Global Initiative on Asthma 2015, and Guía Española del Manejo del Asma 2015 (2016 updates included). After 3 Delphi-rounds we developed an evidence-based document taking into account patient characteristics, including age, treatment costs and safety and best locally available medication. CONCLUSIONS: In cooperation pulmonologists, allergists, ENT physicians, paediatricians and GPs were able to develop an evidence-based document for the prevention, diagnosis and treatment of asthma and its exacerbations in Mexico.


Antecedentes: Con el objetivo de unificar el manejo del asma en México se estructuró una guía clínica que conjunta el conocimiento de diversas especialidades y la atención en el primer nivel de contacto. Se seleccionaron 3 guías publicadas en el ámbito internacional para su transculturación. Métodos: Conforme a la metodología ADAPTE se usó AGREE II después de la búsqueda bibliográfica de guías sobre asma publicadas entre 2007 y 2015. Se fusionó la realidad local con la evidencia de 3/40 mejores guías. El documento inicial fue sometido a la revisión de representantes de 12 sociedades médicas en varias rondas Delphi hasta llegar a la versión final. Resultados: Las guías base fueron la British Thoracic Society Asthma Guideline 2014, la Global Initiative on Asthma 2015 y la Guía Española del Manejo del Asma 2015. Después de 3 rondas Delphi se desarrolló un documento en el que se consideraron las características de los pacientes según edad, costos de los tratamientos y perfiles de seguridad de los fármacos disponibles en México. Conclusión: Con la cooperación de neumólogos, alergólogos, otorrinolaringólogos, pediatras y médicos generales se llegó a un consenso basado en evidencia, en el que se incluyeron recomendaciones sobre prevención, diagnóstico y tratamiento del asma y sus crisis.

RESUMEN

BACKGROUND: The global prevalence of allergic rhinitis is high. International Study of Asthma and Allergies in Childhood (ISAAC) Phase III reports a total estimated prevalence of 4.6% in Mexico. There is evidence based on allergic rhinitis Clinical Practice Guidelines (CPG), but its promotion, acceptance and application is not optimal or adequate in Mexico. OBJECTIVE: To generate a guideline for the treatment of allergic rhinitis and its impact on asthma by adaptating the 2010 ARIA Guideline to Mexican reality, through a transculturation process applying the ADAPTE methodology. PATIENTS AND METHOD: Using the ADAPTE Methodology, the original 2010 ARIA CPG recommendations were evaluated by the guideline development group (GDG) into which multiple medical specialities managing patients with allergic rhinitis were incoorporated. The GDG valorated the quality of 2010 ARIA, checked and translated key clinical questions. Moreover, the GDG adjusted recommendations, patient preferences and included comments in the context of the Mexican reality (safety, costs and cultural issues). To accomplish this, we ran Delphi panels with as many rounds as necessary to reach agreement. One extra question, not included in the original 2010 ARIA, on the use of Nasal Lavages for AR was created sustained by a systematic literature review. RESULTS: A total of 45 questions from the original 2010 ARIA were included and divided into six groups covering prevention, medical treatment, immunotherapy and alternative medicine to treat patients with allergic rhinitis with or without asthma. Most of the questions reached agreement in one or two rounds; one question required three rounds. CONCLUSIONS: An easy-to-use, adaptated, up-to-date and applicable allergic rhinitis guideline for Mexico is now available.


ANTECEDENTES: la prevalencia de rinitis alérgica en todo el mundo es alta. El Estudio Internacional de Asma y Alergias en la Niñez (ISAAC de International Study of Asthma and Allergies in Childhood) Fase III reporta una prevalencia estimada total en México de 4.6%. Existen guías de práctica clínica basadas en evidencia de rinitis alérgica, pero su promoción, aceptación y validez no son óptimas ni adecuadas para México. OBJETIVO: generar una guía de tratamiento de la rinitis alérgica y su repercusión en el asma adaptando la guía ARIA 2010 a la realidad mexicana mediante un proceso de transculturización, por medio de la metodología ADAPTE. MATERIAL Y MÉTODO: a través de la metodología ADAPTE un grupo de desarrollo de la guía, integrado por múltiples especialistas que tratan pacientes con rinitis alérgica, valoró la calidad de la guía ARIA 2010, revisó y tradujo las preguntas clínicas clave y ajustó las recomendaciones, preferencias del paciente y comentarios a la realidad mexicana (seguridad, costos y aspectos culturales). Para lograrlo se corrieron páneles Delphi, con tantas rondas como fuera necesario hasta lograr un acuerdo. Por medio de una revisión sistemática de la bibliografía se creó una pregunta especial no incluida en ARIA 2010 de la utilidad de realizar lavados nasales en pacientes con rinitis alérgica. RESULTADOS: se incluyeron 45 preguntas de la guía original ARIA 2010, divididas en seis bloques que abarcan prevención, tratamiento médico, inmunoterapia y terapias alternativas de pacientes con rinitis alérgica con o sin asma. La mayor parte de las preguntas alcanzaron acuerdo en una a dos rondas, sólo una requirió tres para ello. CONCLUSIONES: se cuenta ahora con una guía de rinitis alérgica de usosencillo, adaptada, actualizada y válida para México.

RESUMEN

BACKGROUND: Urticaria is a disease that a fifth of the population shallsuffer once in a lifetime. Recent clinical guidelines have proposed some fundamental changes in the diagnosis and treatment of urticaria, making the development of a national, multidisciplinary guideline, with wide acceptability among different professional groups -both specialists and primary health care workers-, necessary in Mexico. MATERIAL AND METHOD: Internationally recognized tools for guidelinedevelopment were used. An interdisciplinary group of clinical experts (some of them knowledgeable in methodology of guideline development) determined the objectives and scope of the Evidence Based Clinical Practice Guideline with SCOPE. It was decided to adapt and transculturize international guidelines on the diagnosis and treatment of urticaria. With AGREE-II three high-quality guidelines (Zuberbier 2014, Sánchez-Borges 2012, Powell 2007) were selected to function as basic guidelines (BG). A set of Clinical Questions was formulated that lead to recommendations/suggestions, based on these BG, taking into account the cultural and economic background of Mexico, according to GRADE recommendation development. RESULTS: By a formal process of discussion and voting during several working-sessions, experts and first level healthcare physicians determined the wording of the final guideline, taking particularly care of developing a document, adjusted to the reality, values and preferences of the Mexican patients. The use of oral second generation, non-sedating antihistamines as first line treatment is emphasized. CONCLUSION: This document is an Evidence Based Clinical Practice Guideline for the diagnosis and treatment of acute and chronic urticaria, based on three, high quality, international guidelines. It was developed by a multidisciplinary group. Tables and algorithms make the guideline user-friendly for both, first line health care physicians and specialists.


Antecedentes: la urticaria es una enfermedad que padece una quinta parte de la población en algún momento de su vida. Las guías internacionales recientes han propuesto unos cambios de fondo en su diagnóstico y tratamiento, por lo que había la necesidad de crear una guía nacional y multidisciplinaria, con base amplia en los gremios de especialistas y médicos de primer contacto en México. Material y método: un grupo interdisciplinario de expertos clínicos y algunos expertos en metodología determinó los objetivos y alcances de la Guía de Práctica Clínica Basada en Evidencia con el instrumento SCOPE. Se decidió llevar a cabo la adaptación y transculturización de guías internacionales para el diagnóstico y tratamiento de urticaria. Con el instrumento AGREE-II se seleccionaron las tres guías de alta calidad, como guías base (Zuberbier 2014, Sánchez-Borges 2012, Powell 2007) para formular y contestar la preguntas clínicas clave, en el contexto cultural y económico mexicano, según el método de desarrollo de recomendaciones GRADE. Resultados: mediante un proceso formal de discusión y votación durante varias juntas de expertos, se terminó la redacción de la forma final de la guía, con especial cuidado de lograr un ajuste a las realidades, valores y preferencias de los pacientes de México. Se hace hincapié en la administración de antihistamínicos vía oral de segunda generación, como tratamiento de primera elección. Conclusión: este documento es una Guía de Práctica Clínica Basada en Evidencia para el diagnóstico y tratamiento de urticaria aguda y crónica, basada en tres guías internacionales de alta calidad. Se desarrolló por un grupo multidisciplinario. Los cuadros y algoritmos hacen a la guía amigable para su uso por médicos de primer contacto y por especialistas.

RESUMEN

BACKGROUND: Several international guidelines on immunotherapy exist, but they only apply partially in Mexico. The Mexican guideline of immunotherapy dates from 1998. OBJECTIVES: To establish clinical recommendations and suggestions for Allergy residents and specialists for skin testing and allergen immunotherapy based on evidence and Mexican expert opinion, according to the GRADE system. METHODS: The guidelines were developed following the methodology of a guideline for clinical practice starting with the formulation of clinical questions, in the context of Mexican environmental conditions and morbidity, with the participation of allergists from all regions of the country. External validation was obtained. Its development followed three steps: 1. formulation of 24 clinical questions. 2. Search for consensus on the answers among members of the Regional chapters of both Mexican Colleges of Allergists (CMICA and COMPEDIA) during regional meetings. 3. Literature search for articles related to the questions and grading of its quality according to GRADE. RESULTS: Based on the regional consensus, 116 articles and the safety, patient acceptance/ comfort and cost clinical recommendations and suggestions were developed on basic aspects of skin testing, subcutaneous and sublingual immunotherapy (patient preparation, vial preparation and application schedules) and the treatment of eventual adverse reactions. CONCLUSIONS: A clinical guideline was developed respecting particular methodology, validated by CMICA and COMPEDIA for its implementation among Mexican allergists. Several aspects deserve further study to improve scientific evidence. KEYWORDS: Allergen immunotherapy, subcutaneous immunotherapy, sublingual immunotherapy, skin testing, allergy diagnosis, rhinitis, asthma, atopic dermatitis, house dust mite, pollens, anaphylaxis, adrenaline, Mexico.

RESUMEN

Anemia por trastornos hemolíticos es una patología común del periodo neonatal y tiene etiología múltiple. La característica fundamental de este tipo de anemia es la reducción de la semidesintegración del eritrocito. La anemia hemolítica durante el periodo neonatal casi siempre se acompaña con niveles de bilirrubina superiores a 10 a 12 mg/dl.; por tanto es frecuente que el proceso hemolítico sea evidente durante la valoración de la ictericia presente dentro de la primera semana de vida del recién nacido. Este tipo de anemia hemolítica se presenta dentro de los primeros días después del nacimiento. La forma cl'ásica es frecuente en hospitales de concentración. Pero existe otro tipo de anemia hemolítica de manifestación tardía en etapa neonatal, que no es frecuente, y en la que se presenta destrucción de eritrocitos después de la primera semana de vida. Esta hemólisis puede ser secundaria a la mejoría de la función esplénica, con eliminación eficaz de células sensibilizadas. Si las enzimas hepáticas causales del metabolismo de la bilirrubina también maduraron, la ictericia no acompaña a la reducción de hemoglobina. Deve seguirse de cerca a los recién nacidos con hemólisis leve para poder decubrir casos que desarrollan anemia grave
