The new era of add-on asthma treatments: where do we stand?

Allergy Asthma Clin Immunol 2022 May 21;18(1):42. Epub 2022 May 21.

Division of Pulmonary, Critical Care, and Sleep Medicine, Yale Center for Asthma and Airway Disease, Yale University School of Medicine, New Haven, CT, USA.

Globally, a small proportion (5-12%) of asthma patients are estimated to have severe disease. However, severe asthma accounts for disproportionately high healthcare resource utilization. The Global Initiative for Asthma (GINA) management committee recommends treating patients with asthma with inhaled corticosteroids plus long-acting β-agonists and, when needed, adding a long-acting muscarinic receptor antagonist or biologic agent.

Exome-wide analysis of copy number variation shows association of the human leukocyte antigen region with asthma in UK Biobank.

BMC Med Genomics 2022 May 21;15(1):119. Epub 2022 May 21.

Department of Genetics and Genome Biology, University of Leicester, Leicester, UK.

Background: The role of copy number variants (CNVs) in susceptibility to asthma is not well understood. This is, in part, due to the difficulty of accurately measuring CNVs in large enough sample sizes to detect associations. The recent availability of whole-exome sequencing (WES) in large biobank studies provides an unprecedented opportunity to study the role of CNVs in asthma. Read More

[Therapeutic adherence among asthma patients: Variations according to age groups. How can it be improved? The potential contributions of new technologies].

Rev Mal Respir 2022 May 18. Epub 2022 May 18.

Service de pneumologie, UF tabacologie, hôpital Tenon, DMU APPROCHES, Paris, France.

While asthma patients' treatment adherence (TA) generally leaves to be desired, few data exist on TA evolution from age group to another. During the meeting of a working group of pneumo-pediatricians and adult pulmonologists, we reviewed the literature on adherence according to age group, examined explanations for poor adherence, and explored ways of improving adherence via new technologies. Asthma is a chronic disease for which TA is particularly low, especially during adolescence, but also among adults. Read More

Current and Emerging Strategies to Inhibit Type 2 Inflammation in Atopic Dermatitis.

Dermatol Ther (Heidelb) 2022 May 21. Epub 2022 May 21.

Sanofi, 450 Water Street, Cambridge, MA, USA.

Type 2 immunity evolved to combat helminth infections by orchestrating a combined protective response of innate and adaptive immune cells and promotion of parasitic worm destruction or expulsion, wound repair, and barrier function. Aberrant type 2 immune responses are associated with allergic conditions characterized by chronic tissue inflammation, including atopic dermatitis (AD) and asthma. Signature cytokines of type 2 immunity include interleukin (IL)-4, IL-5, IL-9, IL-13, and IL-31, mainly secreted from immune cells, as well as IL-25, IL-33, and thymic stromal lymphopoietin, mainly secreted from tissue cells, particularly epithelial cells.

Nuclear receptor Nr1d1 alleviates asthma by abating GATA3 gene expression and Th2 cell differentiation.

Cell Mol Life Sci 2022 May 21;79(6):308. Epub 2022 May 21.

Department of Molecular Immunology, Council of Scientific and Industrial Research, Institute of Microbial Technology, Sector 39A, Chandigarh, 160036, India.

Nuclear receptors are a unique family of transcription factors that play cardinal roles in physiology and plethora of human diseases. The adopted orphan nuclear receptor Nr1d1 is a constitutive transcriptional repressor known to modulate several biological processes. In this study, we found that Nr1d1 plays a decisive role in T helper (Th)-cell polarization and transcriptionally impedes the formation of Th2 cells by directly binding to the promoter region of GATA binding protein 3 (GATA3) gene.

A Nurse Led Asthma Care Team transitioning patients from hospital to home improves asthma control: a pilot study exploring an alternative model of care.

Health Promot J Austr 2022 May 20. Epub 2022 May 20.

Department of Respiratory Medicine, Western Health, Melbourne, VIC, Australia.

Introduction: Recurrent asthma admissions are frequent in our patients at a tertiary Australian hospital, and commonly related to poor health literacy and medication adherence. A need exists to improve these asthma self-management skills within our current model of care, especially during the vulnerable post discharge period.

Aim: To examine if the addition of a nurse led Asthma Care Transition Team (ACTT) compared with usual care alone (UC) (1)improves asthma control at 12 weeks post hospital discharge; (2) the number of patients using a Written Action Plan (WAP), compliance with inhaler therapy at 12 weeks, and readmission rates at 6 months.
