Exhaled Nitric Oxide and Sputum Eosinophils Are Complementary Tools for Diagnosing Occupational Asthma.

Background: Exposure-related changes in exhaled nitric oxide (FeNO) and sputum eosinophils have not been thoroughly compared in the investigation of occupational asthma.

Objective: This study aimed at comparing the accuracies of the changes in FeNO concentrations and sputum eosinophil counts in identifying asthmatic reactions induced by occupational agents during specific inhalation challenges (SICs).

Methods: This retrospective multicenter study included 321 subjects who completed an assessment of FeNO and sputum eosinophils before and 24 h after SICs with various occupational agents, of whom 156 showed a positive result.

Signature Proteins in Small Extracellular Vesicles of Granulocytes and CD4 T-Cell Subpopulations Identified by Comparative Proteomic Analysis.

Several studies have described the proteomic profile of different immune cell types, but only a few have also analysed the content of their delivered small extracellular vesicles (sEVs). The aim of the present study was to compare the protein signature of sEVs delivered from granulocytes (i.e.

Immunological Effects of Diesel Particles in a Murine Model of Healthy Mice.

Exposure to environmental pollutants such as diesel exhaust particles (DEP) increases the risk of respiratory disease exacerbation. However, the possible effects of these particles on the general population remain poorly understood. The present study aimed to assess the immunomodulatory and inflammatory effects of the inhalation of DEP in a model of healthy mice undergoing short-, mid- and long-term exposure.

The Impact of the Reduction in Environmental Pollution during COVID-19 Lockdown on Healthy Individuals.

The lockdown imposed to combat the COVID-19 pandemic produced a historic fall in air pollution in cities like Barcelona. This exceptional situation offered a unique context in which to examine the effects of air pollutants on human health. The present study aims to determine and compare the oxidative stress biomarkers Th1/Th2 and inflammatory-related cytokines in healthy individuals first during lockdown and then six months after the easing of the restrictions on mobility.

Increased TGFβ1, VEGF and IFN-γ in the Sputum of Severe Asthma Patients With Bronchiectasis.

Background: Bronchiectasis is one of the most common comorbidities in severe asthma. However, the mechanisms by which asthma promotes the development and progress of this condition are not well defined. This study aimed to analyze the inflammatory phenotypes and quantify the expression of proinflammatory and remodeling cytokines in asthma patients with and without bronchiectasis.

Maintenance Inhalers for Asthma and COPD in Spain.

Background: This study aimed to describe the use of pressurized metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs) in Spanish subjects in terms of sociodemographic, clinical, and functional characteristics in subjects with asthma or COPD on maintenance treatment with inhaled therapy.

Methods: This was a retrospective, descriptive, national, multi-center, and observational study using a database with 1.8 million patients from hospitals and primary care centers as a secondary information source.

Acquired tracheomalacia due to SARS-CoV-2 pneumonia.

Introduction: Several studies mentioned parenchymal findings after SARS-CoV-2 pneumonia, but few studies have mentioned alterations in the airways. The aim of this study was to estimate the prevalence of tracheomalacia and to analyse the clinical characteristics in a cohort of patients with SARS-CoV-2.

Methods: The study population consisted of all patients with SARS-CoV-2 admitted a hospital serving a population of 500 000 inhabitants.

Sensitization to avian and fungal proteins in different work environments.

Introduction: Hypersensitivity pneumonitis (HP) is usually caused by the inhalation of avian and fungal proteins. The present study assesses a cohort of Urban Pest Surveillance and Control Service (UPSCS) workers with high exposure to avian and fungal antigens, in order to identify their degree of sensitization and the potential risk of developing HP.

Methods: Workers were divided according to their work activity into Nest pruners (Group 1) and Others (Group 2).

The Role of Inflammatory Phenotype in Patients With Exacerbation-prone Asthma and Ongoing Therapy.

Introduction: The risk factors for having frequent exacerbations are not well documented in cohort studies of patients with asthma on existing therapy. The objective of the present study was to compare the clinical and inflammatory characteristics of patients with exacerbation-prone asthma (EPA) with a history of two or more exacerbations in the previous year with those who had presented just one or no exacerbation.

Methods: An ambispective observational study was conducted in a tertiary hospital.

[A Study of the Prevalence of Asthma in the General Population in Spain].

Introduction: Asthma is a disease with high prevalence, which affects all age groups and generates high health and social care costs. Studies carried out in a number of populations show great variability in its prevalence, even in geographically close populations, with data suggesting a relevant influence of socio-economic factors. At present, we do not have reliable data on the prevalence of this disease in the adult population of Spain.

Efficacy and Potential Positioning of Tezepelumab in the Treatment of Severe Asthma.

The excellent results for monoclonal antibodies in the treatment of severe uncontrolled asthma (SUCA) represent a milestone in current treatment of asthmatic disorders. Remaining, however, are several subsidiary areas for improvement in which new biologics are expected to make a decisive contribution. These biologics include tezepelumab, a monoclonal antibody that blocks thymic stromal lymphopoietin (TSLP).

[Consensus document for severe asthma in adults. 2022 update].

Severe asthma is a heterogeneous syndrome with several clinical variants and often represents a complex disease requiring a specialized and multidisciplinary approach, as well as the use of multiple drugs. The prevalence of severe asthma varies from one country to another, and it is estimated that 50% of these patients present a poor control of their disease. For the best management of the patient, it is necessary a correct diagnosis, an adequate follow-up and undoubtedly to offer the best available treatment, including biologic treatments with monoclonal antibodies.

Disposition of Work-Related Asthma in a Spanish Asthma Cohort: Comparison of Asthma Severity Between Employed and Retired Workers.

Background: Exposure to certain agents in the workplace can trigger occupational asthma or work-exacerbated asthma, both of which come under the heading of work-related asthma (WRA). Understanding the burden that WRA represents can help in the management of these patients.

Objective: To assess the influence of occupation on asthma in real life and analyze the characteristics of patients with WRA included in an asthma cohort.
