Five-week-old male and female C57BL/6J mice were challenged with intranasal house dust mite (HDM) allergen or saline 5 days per week for 6 weeks (n = 6–9 per sex, per group). Following each HDM exposure, mice received subcutaneous recombinant human leptin or saline.

Asthma is a common chronic airway disease in the world. The purpose of this study was to explore the expression of IL1-RL1 in sputum and its correlation with Th1 and Th2 cytokines in asthma.
Biologics are currently one of the main treatment options for a number of diseases. The IgG4 monoclonal antibody dupilumab targets the Interleukin-4 receptor alpha chain, thus preventing the biological effects of the cytokines IL-4 and IL-13, that are essential for the Th2 response. Several controlled trials showed that dupilumab is effective and safe in patients with atopic dermatitis (AD), severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP), thus resulting in approval by regulatory agencies.
Corticosteroids remain a key therapy for treating children with asthma. Patients with severe asthma are insensitive, resistant, or refractory to corticosteroids and have poorly controlled symptoms that involve airway inflammation, airflow obstruction, and frequent exacerbations. While the pathways that mediate corticosteroid insensitivity in asthma remain poorly defined, recent studies suggest that enhanced Th1 pathways, mediated by TNFα and IFNγ, may play a role. We previously reported that the combined effects of TNFα and IFNγ promote corticosteroid insensitivity in developing human airway smooth muscle (ASM).

Abstract
A literature search was conducted on Embase and Medline.
Clinical studies published in English and published between 1999 and 2020 were selected.
ABSTRACT
BACKGROUND: During the SARS-COV-2 pandemic, using face masks became mandatory in many countries. Although evidence suggests that masks can exacerbate several inflammatory skin diseases, few studies focus on their real impact on eczema localized to the face in atopic dermatitis (AD) patients.
ABSTRACT
Asthma is usually associated with pulmonary and extrapulmonary comorbidities that are more common in patients with severe asthma than in those with mild-to-moderate illness or in the general population. These comorbidities may affect the clinical intensity and severity of asthma and, as a result, increase health care costs related to its therapy. On the other hand, their recognition and appropriate treatment appear to improve asthma outcomes while optimizing therapy by preventing overtreatment. Comorbid conditions such as gastroesophageal reflux disease, allergic rhinitis, obesity, depression, diabetes mellitus, and cardiovascular disease are commonly known, though their prevalence varies significantly between studies; however, many more comorbidities may remain undiagnosed and only be discovered in an experienced specialized environment.
