Silibinin, a PLC-β3 inhibitor, inhibits mast cell activation and alleviates OVA-induced asthma.

The immunoglobulin E (IgE) receptor FcεRI (Fc epsilon RI) plays a crucial role in allergic reactions. Recent studies have indicated that the interaction between FcεRIβ and the downstream protein phospholipase C beta 3 (PLCβ3) leads to the production of inflammatory cytokines. The aim of this study was to develop small molecules that inhibit the protein-protein interactions between FcεRIβ and PLCβ3 to treat allergic inflammation.

In utero exposure to experimental maternal asthma alters fetal airway development in sheep.

The mechanisms linking maternal asthma (MA) exposure in utero and subsequent risk of asthma in childhood are not fully understood. Pathological airway remodelling, including reticular basement membrane thickening, has been reported in infants and children who go on to develop asthma later in childhood. This suggests altered airway development before birth as a mechanism underlying increased risk of asthma in children exposed in utero to MA.

Background: Respiratory syncytial virus (RSV) is an important cause of lower respiratory tract infection, hospitalisation and death in adults.

Methods: Based on evidence regarding the impact of RSV on adult populations at risk for severe infection and the efficacy and safety of RSV vaccines, the Portuguese Society of Pulmonology, the Portuguese Association of General and Family Medicine, the Portuguese Society of Cardiology, the Portuguese Society of Infectious Diseases and Clinical Microbiology, the Portuguese Society of Endocrinology, Diabetes and Metabolism, and the Portuguese Society of Internal Medicine endorses this position paper with recommendations to prevent RSV-associated disease and its complications in adults through vaccination.

Conclusion: The RSV vaccine is recommended for people aged ≥50 years with risk factors (chronic obstructive pulmonary disease, asthma, heart failure, coronary artery disease, diabetes, chronic kidney disease, chronic liver disease, immunocompromise, frailty, dementia, and residence in a nursing home) and all persons aged ≥60 years.

The Impact of the Indoor Environment on Childhood Asthma.

Purpose Of Review: This manuscript reviews the impact of important indoor environmental exposures on pediatric asthma, with a focus on recent literature in the field.

Recent Findings: Studies continue to support an association between numerous indoor aeroallergens and air pollutants found in homes and schools and increased asthma morbidity overall. Several recent home and school intervention studies have shown promise, though results have been overall mixed.

Individual and system-level determinants of caregivers' quality of life among inner-city preschool children with asthma.

Caregivers of children with asthma can become overwhelmed by the burden of care provision. Guided by the socioecological framework, we examined individual and system-level factors associated with caregiver health-related quality of life (HRQoL) among preschool children (aged two to six years) enrolled in a multilevel home- and school-based asthma educational intervention in Baltimore, Maryland. Primary outcome was caregiver HRQoL measured at baseline and six months.

Retrospective Cohort Study of Elderly Users of Single- or Multiple-Inhaler Triple Therapy for the Treatment of Asthma in the USA.

Introduction: Escalation to single- or multiple-inhaler triple therapy (SITT; MITT) is a recommended option for patients with asthma who remain uncontrolled by medium-dose inhaled corticosteroid/long-acting β-agonist; however, characterization of elderly users of triple therapy is limited. This real-world cohort study describes demographics and clinical characteristics of elderly patients with asthma with and without comorbid chronic obstructive pulmonary disease (COPD) who are new users of triple therapy, and asthma treatment patterns preceding triple therapy initiation.

Methods: This retrospective cohort study used administrative claims data from the Optum Clinformatics Data Mart database.

Concordance Between Asthma Symptom Reports and Objective Lung Function, and Associations With Sleep Outcomes in Urban Children.

Objectives: To examine the extent to which asthma symptom concordance (ASC) or discordance (ASD) is associated with sleep outcomes in children with persistent asthma. Also, to investigate whether the association between ASC and sleep outcomes varies as a function of children's level of asthma control and severity.

Methods: A retrospective data analysis of Project NAPS (Nocturnal Asthma and Performance in School), an observational study which examined asthma and sleep outcomes in children with persistent asthma.

Distinct single cell transcriptional profile in CD4+ T-lymphocytes among obese children with asthma.

Obesity is a risk factor for asthma morbidity, associated with less responsiveness to inhaled corticosteroids. CD4+ T-cells are central to the immunology of asthma and may contribute to the unique obese asthma phenotype. We sought to characterize the single cell CD4+ Transcriptional profile differences in obese children with asthma compared to normal weight children with asthma.

New approaches in childhood IgE-mediated food allergy treatment.

Purpose Of Review: This review aims to provide an overview of the current and future treatment options for children with food allergies (FAs), highlighting the latest research findings and the potential impact of these new approaches on improving patients' and caregivers' quality of life.

Recent Findings: In the last decade, many promising approaches have emerged as an alternative to the standard avoidance of the culprit food with the risk of severe accidental reactions. Desensitization through oral immunotherapy has been introduced in clinical settings as a therapeutic approach, and more recently also omalizumab.

Cumulative Dispensing of Oral Corticosteroids Over 12 Months in People with COPD.

Purpose: Oral corticosteroids (OCS) are recommended for the treatment of exacerbations in people with COPD; however, high cumulative lifetime doses (≥1000mg prednisolone-equivalent) are associated with adverse health effects. This issue is well defined in asthma but is less well understood in COPD. The aim of this study was to examine cumulative OCS dispensed to people with COPD over 12 months.

Roads to remission: evolving treatment concepts in type 2 inflammatory diseases.

Unlabelled: Non-communicable diseases (NCDs) characterised by type 2 inflammation, including asthma, allergic rhinitis, chronic rhinosinusitis with nasal polyps, atopic dermatitis, food allergies and eosinophilic esophagitis, are increasing in prevalence worldwide. Currently, there is a major paradigm shift in the management of these diseases, towards the concept of disease modification and the treatment goal remission, regardless of severity and age. Remission as a treatment goal in chronic inflammatory NCDs was first introduced in rheumatoid arthritis, and then adopted in other non-type 2 inflammatory diseases.
