Autoimmune chronic spontaneous urticaria

Pavel Kolkhir, Melba Munoz, Riccardo Asero, Marta Ferrer, Emek Kocaturk, Martin Metz, Yi-Kui Xiang, Marcus Maurer

Summary: Chronic spontaneous urticaria (CSU) is a mast cell-driven disease characterized by recurrent wheals and/or angioedema, with two main autoimmune mechanisms: type I autoallergic CSU and type IIb autoimmune CSU. The latter is less common but more severe, and new targeted therapies are under development for CSU treatment.

Mechanisms and pathogenesis of chronic rhinosinusitis

Atsushi Kato, Robert P. Schleimer, Benjamin S. Bleier

Summary: Chronic rhinosinusitis (CRS) is a heterogeneous disease characterized by inflammation in the upper airways, which can be divided into two main types based on the presence of nasal polyps. The inflammation is characterized by three different endotypes based on the elevation of specific cytokines. The sinonasal epithelium plays a crucial role in the pathogenesis of CRS by acting as a barrier and participating in both innate and adaptive immunity. Further research is needed to fully understand the mechanisms of CRS pathogenesis.

Summary: The GINA 2021 report provides evidence-based recommendations for asthma management, emphasizing the benefits of inhaled corticosteroids (ICS) and recommending the use of combination ICS-formoterol in two different tracks. Additional recommendations are provided for adults with moderate-to-severe asthma, with options for add-on therapies such as long-acting muscarinic antagonists and azithromycin. Regular personalized assessment and treatment adjustments are essential across all age groups and severity levels to optimize asthma outcomes.

Innovation in the treatment of atopic dermatitis: Emerging topical and oral Janus kinase inhibitors

Chisa Nakashima, Shigeto Yanagihara, Atsushi Otsuka

Summary: Atopic dermatitis is a chronic, eczematous skin condition characterized by severe itchiness. Th2 cell-mediated immunity, skin barrier dysfunction, and pruritus contribute to the development of atopic dermatitis. The JAK/STAT pathway is involved in various inflammatory diseases, including atopic dermatitis. JAK inhibitors show promise as potential treatments for severe atopic dermatitis.

Summary: This study summarizes the latest evidence on risk factors for severe food-induced allergic reactions. The study found significant uncertainties in predicting severe reactions and identified some molecular allergology markers that may be helpful. Age was identified as an important factor in severe reactions, but the contribution of risk-taking behavior remains unclear.

Summary: The study found that asthma is not a risk factor for more severe COVID-19 disease, with allergic asthmatics having a lower risk of hospitalization compared with non-allergic asthmatics. Lower levels of eosinophil counts were associated with a more severe COVID-19 disease trajectory. Recovery time was similar among asthmatics and non-asthmatics, with over 50% of patients reporting ongoing lower respiratory symptoms three months post-infection.
