A Core Outcome Set for Efficacy of Acute Treatment of Hereditary Angioedema.

Background: Clinical trials investigating drugs for the acute treatment of hereditary angioedema attacks have assessed many different outcomes. This heterogeneity limits the comparability of trial results and may lead to selective outcome reporting bias and a high burden on trial participants.

Objective: To achieve consensus on a core outcome set composed of key outcomes that ideally should be used in all clinical efficacy trials involving the acute treatment of hereditary angioedema attacks.

Epithelial alarmins: a new target to treat chronic respiratory diseases.

Introduction: In response to injury, epithelial cells release alarmins including thymic stromal lymphopoietin (TSLP), high mobility group-box-1 (HMGB1), interleukin (IL)-33 and -25 that can initiate innate immune responses. These alarmins are recognized as activators of T2-immune responses characteristic for asthma, but recent evidence highlighted their role in non-T2 inflammation, airway remodeling, and pulmonary fibrosis making them an attractive therapeutic target for chronic respiratory diseases (CRD).

Areas Covered: In this review, firstly we discuss the role of TSLP, IL-33, IL-25, and HMGB1 in the pathogenesis of asthma, COPD, idiopathic pulmonary fibrosis, and cystic fibrosis according to the published data.

The optimal use of drug combinations for the management of asthma is providing significant results. This has prompted Interasma (Global Asthma Association) to take a position on inhaled triple therapy in asthma. We performed an extensive literature research to clinical trials, meta-analyses, randomized controlled trials and systematic reviews.

Climate changes, air pollution and allergic diseases in childhood and adolescence.

Objective: To analyze the impacts of climate change on the development of immature respiratory and immune systems in children.

Source Of Data: The authors of the present study performed a non-systematic review of English, Spanish, and Portuguese articles published in the last five years in databases such as PubMed, EMBASE, and SciELO. The terms used were air pollution OR climate changes OR smoke, AND children OR health.

Climate change and global issues in allergy and immunology.

The steady increase in global temperatures, resulting from the combustion of fossil fuels and the accumulation of greenhouse gases (GHGs), continues to destabilize all ecosystems worldwide. Although annual emissions must be halved by 2030 and reach net zero by 2050 to limit some of the most catastrophic impacts associated with a warming planet, the world's efforts to curb GHG emissions fall short of the commitments made in the 2015 Paris Agreement. To this effect, July 2021 was recently declared the hottest month ever recorded in 142 years.

Identification of an allergenic calmodulin from Amaranthus palmeri pollen.

Introduction: Pollens are an important source of allergens that trigger rhinitis or asthma. The allergenic extracts of pollens used to diagnose and treat allergies contain different allergenic antigens. Isolated allergenic proteins are employed in in vitro assays, skin tests and allergenic-specific immunotherapy.

Manifesto on united airways diseases (UAD): an Interasma (global asthma association - GAA) document.

Objective: The large amount of evidence and the renewed interest in upper and lower airways involvement in infectious and inflammatory diseases has led Interasma (Global Asthma Association) to take a position on United Airways Diseases (UAD).

Methods: Starting from an extensive literature review, Interasma executive committee discussed and approved this Manifesto developed by Interasma scientific network (INES) members.

Results: The manifesto describes the evidence gathered to date and defines, states, advocates, and proposes issues on UAD (rhinitis, rhinosinusitis and nasal polyposis), and concomitant/comorbid lower airways disorders (asthma, chronic obstructive pulmonary disease, bronchiectasis, cystic fibrosis, obstructive sleep apnoea) with the aim of challenging assumptions, fostering commitment, and bringing about change.

Impact of weather and climate change with indoor and outdoor air quality in asthma: A Work Group Report of the AAAAI Environmental Exposure and Respiratory Health Committee.

Weather and climate change are constant and ever-changing processes that affect allergy and asthma. The purpose of this report is to provide information since the last climate change review with a focus on asthmatic disease. PubMed and Internet searches for topics included climate and weather change, air pollution, particulates, greenhouse gasses, traffic, insect habitat, and mitigation in addition to references contributed by the individual authors.

[Determination and analysis of protein profile of different transfer factors].

Background: The transfer factor (TF) is the dialyzable extract of leukocytes with cellular immunity transfer properties. Its use has spread in the treatment of a wide range of immunologic, infectious, and even oncological diseases. However, important aspects in their protein profile, component concentrations, and a well-defined action mechanism are not completely unknown.

[Profilins: allergens with clinical relevance].

Introduction: Profilins are small ubiquitous proteins of 12-19 kDa involved in actin dynamics. These proteins are found in all eukaryotic organisms studied to date. Profilins have aminoacid sequences and tridimensional structure highly conserved.
