Serum integrin accumulation during asthma exacerbation: The role of matrix metalloproteinases.

The inflammation caused by asthma exacerbation can lead to permanent changes in the airways and loss of lung function. Integrins are membrane receptors that interact with components of the extracellular matrix and cell adhesion molecules. It is known that these receptors can be found in soluble form in some conditions such as asthma, but it is unknown if exacerbation during asthma leads to soluble integrins.

Objetivo: Determinar la carga económica anual del asma, desde una perspectiva institucional y con base en la clasificación recomendada por GINA, en una cohorte retrospectiva de adultos atendidos en el Instituto Nacional de Enfermedades Respiratorias (INER) de México.

MÉtodos: Estudio observacional, longitudinal y retrospectivo, llevado a cabo a partir de la información recabada de 247 pacientes femeninas con asma. Se estimaron los costos directos anuales: visitas, pruebas de laboratorio, tratamiento farmacológico y de las crisis o exacerbaciones, para determinar la carga anual de la enfermedad desde una perspectiva institucional, y según la clasificación de la Iniciativa Global para el Asma.

Benralizumab in severe eosinophilic asthma: A real-world, single-center, observational study from Mexico.

Introduction: Urbanization has increased the prevalence of asthma in lower- and middle-income countries. Severe eosinophilic asthma (SEA), a subtype of asthma, can be refractory to standard therapy. Biologics such as benralizumab target interleukin-5 and have demonstrated effectiveness in managing SEA.

An independent in-depth analysis proposing adjusted Global Initiative on Asthma Step 1-2 treatment suggestions.

The Global Initiative on Asthma (GINA) strategy included major changes for the treatment of mild asthma in the 2020 version that are even taken to the next level in 2021, leaving a preferred track with only rescue therapy with inhaled corticosteroid and formoterol (ICS-FORM) for steps 1-2 in 12+ years old. It has been questioned how solid the evidence behind these recommendations is. We decided to independently conduct an in-depth analysis of published evidence based on a comprehensive evaluation of original articles and related appendices and publications, including quality of evidence and risk of bias per article.

An online survey detected knowledge gaps and cost-saving opportunities in asthma maintenance treatment among allergists, pulmonologists, ENTs and primary care.

Background: In April 2017 the Mexican Asthma Guidelines (GUIMA) were published. Before the launch, physicians' knowledge was explored related to key issues of the guideline.

Methods: A SurveyMonkey® survey was sent out to board-certified physicians of 5 medical specialties treating asthma.

Pediatric asthma treatment: What to do when international guideline recommendations do not agree.

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.

[Mexican Asthma Guidelines: GUIMA 2017].

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.
