Rev Alerg Mex 2019 Jan-Mar;66(1):140-146

Médica Sur, Centro de Excelencia en Asma y alergia, Ciudad de México, México.

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.

[Allergen-derived peptide: A promising approach in asthma].

Rev Mal Respir 2019 Apr 18. Epub 2019 Apr 18.

Inra, UR 1268 BIA, 44316 Nantes, France. Electronic address:

Severe asthma required high dose of corticosteroids combined with biotherapies to control more or less asthma symptoms and lead to the decrease of patients' quality of life on long term. Recent studies show that hypoallergenic peptides derived from allergen can prevent airway hyperresponsiveness, decrease Th2 response and also allergen-specific IgE in mouse models of allergic asthma. Even if some peptides mechanisms remain unknown, their fast efficacy with low doses of allergens make peptide immunotherapy a new promising approach in allergic asthma. Read More

B Cell Responses: Cell Interaction Dynamics and Decisions.

Cell 2019 Apr;177(3):524-540

Cardiovascular Research Institute, Department of Anatomy, and Sandler Asthma Basic Research Center, University of California, San Francisco, San Francisco, CA 94143, USA. Electronic address:

B cells and the antibodies they produce have a deeply penetrating influence on human physiology. Here, we review current understanding of how B cell responses are initiated; the different paths to generate short- and long-lived plasma cells, germinal center cells, and memory cells; and how each path impacts antibody diversity, selectivity, and affinity. We discuss how basic research is informing efforts to generate vaccines that induce broadly neutralizing antibodies against viral pathogens, revealing the special features associated with allergen-reactive IgE responses and uncovering the antibody-independent mechanisms by which B cells contribute to health and disease.

Chest 2019 Apr 16. Epub 2019 Apr 16.

Division of Pulmonary, Allergy, and Critical Care Medicine, Department of Medicine, UMass Memorial Medical Center, Worcester, MA, USA.

Background: Whether gastroesophageal reflux (GER) or GER disease (GERD) causes chronic cough in children is controversial. Using the PICO format, we undertook 4 systematic reviews. For children with chronic cough (>4-weeks duration) and without underlying lung disease: (1) who do not have gastrointestinal GER symptoms, should empirical treatment for GERD be used? (2) with gastrointestinal GER symptoms, does treatment for GERD resolve the cough? (3) with or without gastrointestinal GER symptoms, what GER-based therapies should be used and for how long? (4) if GERD is suspected as the cause, what investigations and diagnostic criteria best determine GERD as the cause of the cough?

Methods: We used the CHEST Expert Cough Panel's protocol and American College of Chest Physicians (CHEST) methodological guidelines and GRADE framework. Read More

Omalizumab, a recombinant humanized monoclonal antibody targeting the IgE molecule, is the first biologic approved for moderate-to-severe allergic asthmatics, who remain uncontrolled despite high dose inhaled corticosteroid and bronchodilators. Steroid-sparing effect of omalizumab has not been demonstrated in asthmatics with persistent airway eosinophilia in a randomised controlled trial till date. From this double-blind, placebo-controlled, multi-centred, randomized parallel group design, we report that omalizumab is possibly inadequate to control sputum eosinophilia, and therefore may not have a steroid-sparing effect, especially in those maintained on oral corticosteroids daily.

PTGDR expression is upregulated through retinoic acid receptors (RAR) mechanism in allergy.

PLoS One 2019 15;14(4):e0215086. Epub 2019 Apr 15.

Department of Biomedical and Diagnostic Sciences, University of Salamanca, Salamanca, Spain.

Functional studies suggest that promoter polymorphisms of the Prostaglandin D Receptor (PTGDR) gene can be involved in asthma. All-trans Retinoic acid (ATRA) has also been linked to allergic diseases. We have previously described the PTGDR promoter activation mediated by ATRA through response elements (RARE) at position -549T> C. Read More

Progressive increase of FcεRI expression across several PBMC subsets is associated with atopy and atopic asthma within school-aged children.

Pediatr Allergy Immunol 2019 Apr 15. Epub 2019 Apr 15.

Telethon Kids Institute, University of Western Australia, WA, Australia.

Background: Antigen specific IgE binds the Fcε receptor I (FcεRI) expressed on several types of immune cells, including dendritic cells (DC). Activation of FcεRI on DCs in atopics has been shown to modulate immune responses that potentially contribute to asthma development. However, the extent to which DC subsets differ in FcεRI expression between atopic children with or without asthma is currently not clear. Read More

The Patient Needs in Asthma Treatment (NEAT) questionnaire: Further evidence on its psychometric properties.

Allergy 2019 Apr 15. Epub 2019 Apr 15.

Institute of Occupational, Social and Environmental Medicine, Centre for Health and Society, Faculty of Medicine, University of Düsseldorf, Düsseldorf, Germany.

Background: Building on previous psychometric work, we sought to assess the Patient Needs in Asthma Treatment (NEAT) questionnaire's validity, responsiveness to change and the minimal important change (MIC) over a 3-year period (Study 1) and its reliability and the smallest detectable change (SDC) in a test-retest-study (Study 2) among patients self-reporting physician-diagnosed asthma.

Methods: In Study 1, a total of 207 patients completed a survey which included the NEAT, the Asthma Control Test (ACT), the Asthma Quality of Life Questionnaire-Sydney (AQLQ-S) and a question on treatment satisfaction in 2014 and 2017. In Study 2, a total of 78 patients completed NEAT twice on average four weeks apart in 2018. Read More

IgE sensitization in a cohort of adolescents in southern Sweden and its relation to allergic symptoms.

Clin Mol Allergy 2019 2;17. Epub 2019 Apr 2.

Department of Respiratory Medicine and Allergology, Skåne University Hospital, Lund University, Lund, Sweden.

Background: There is a strong and consistent association between IgE sensitization and allergy, wheeze, eczema and food hypersensitivity. These conditions are also found in non-sensitized humans, and sensitization is found among individuals without allergy-related diseases. The aim of this study was to analyse the sensitization profile in a representative sample of the population, and to relate patterns of allergens and allergen components to allergic symptoms.
