Active clinical trials for "Pulmonary Eosinophilia"

Chronic airway inflammation rich in eosinophils is an important feature seen in asthma. Airway and blood eosinophilia is associated with increased rates of asthma exacerbations and more intense treatment. Recently, the existence of two distinct eosinophils subtypes was revealed-lung-resident eosinophils (rEOS), which maturate independently to interleukin (IL) 5, with the primary function to maintain tissue homeostasis, and inflammatory eosinophils (iEOS), which mature in IL-5-dependent manner and are mainly involved in immune responses. Eosinophils' effect on the airway remodeling in asthma depends not only on the activity but also by their viable number in the lungs. Blood iEOS infiltrate the airways mainly after the environmental stimulus like allergen and leave the airways with bronchial secretions. However, rEOS reside lung tissue for their entire lifetime regulating local immunity. Blood rEOS and iEOS ratio alters in asthma, compared with healthy controls. It is known that the predominant eosinophils subtype in allergic asthma are iEOS, while rEOS are basic subtype in severe eosinophilic asthma patients, moreover, they are different in adhesive properties and survivability as well. Distinct biological properties allows to speculate about their different functions in asthma, however, there are still little information. Data about differently expressed microRNA (miRNA) profiles in eosinophils in asthma suggests, that eosinophils subtypes can be distinct in non-coding RNA (ncRNA) - microRNA (miRNA), piwi-interacting RNA (piRNA) and long non-coding RNA (IncRNA) profiles that could describe their role in asthma pathogenesis and act as biomarkers to discern asthma phenotypes.

This study investigates the effect of removing eosinophils from peripheral blood (using treatment with Benralizumab, which is approved for the treatment of severe eosoniphilic asthma) on circulating dendritic cells in patients with severe eosinophilic asthma.

In asthma, the type and importance of the inflammatory response in the airways has allows identification of different phenotypes. Of these, one of the most common is eosinophilic asthma, based on induced sputum differential cell count. Patients with severe asthma and an eosinophilic asthma phenotype have different pathophysiological characteristics than those seen in patients with with mild asthma. However, few studies have compared patients with eosinophilic phenotype according to the severity of asthma. In addition, the stability of the phenotype based on the sputum results has been criticized. This study aims to describe the characteristics of patients with eosinophilic asthma phenotype according to the severity of asthma and determine the stability of the phenotype.

The purpose of this study is to identify gene transcripts after initiation of mepolizumab in individuals with severe eosinophilic asthma (SEA), and to determine the composition of immune cells present in the microenvironment of individuals with SEA after initiation of mepolizumab.

Observational, retrospective study in adults (≥18 years) with severe asthma (maintenance treatment with high dose inhaled corticosteroids combined with long-acting agonist β2) and eosinophilic phenotype, who at the discretion of the investigator were candidates to receive benralizumab in the individualized access program approved by national health authorities. Primary Objective: To describe the demographic and baseline characteristics in patients with severe eosinophilic asthma who participated in the individualized access program approved in Spain and received at least one dose of benralizumab. Secondary Objectives: To describe clinical outcomes in severe eosinophilic asthma patients who received at least three doses of benralizumab in the individualized access program.

BEEPS describes the utility of patient reported outcomes (PRO) as simple, pragmatic, and sensitive tool to assess early treatment response of benralizumab to document the level of asthma control and change in medication after 1 to 16 weeks post-treatment initiation including use of OCS. The generated data on the time of asthma symptom relief after initiation of benralizumab will support patient management for a better disease control in severe asthma patients under benralizumab treatment. To assess long term outcomes the patients will have a last mandatory visit after 56 weeks, with no visits scheduled between week 16 and 56.

The purpose of this observational study is to describe the population of patients with SEA + NP who have been prescribed FASENRA and assess available clinical outcomes for both NP and asthma.

Daptomycin is an antibiotic from the family of cyclic lipopeptides, bactericide, concentration-dependent. Its spectrum concerns Gram-positive bacteria. Since the authorization of daptomycin in 2006, cases of eosinophilic pneumonia and pulmonary eosinophilia associated with its use have been reported in Europe and worldwide. The purpose of this study is to describe the mechanism of occurrence of this AE with dapto; Prolonged exposure and accumulation at the alveolar level could potentially have a role. Better understanding the mechanisms of appearance of this AE would provide predictive elements making it possible to limit the occurrence of this AE in the future

Retrospective, multicenter, routine clinical practice study with consecutive inclusion of adult patients with severe eosinophilic asthma receiving benralizumab treatment.

Daily physical activity in adult patients with asthma remains overlooked. Limited evidence demonstrates reduced levels of daily physical activity in asthma populations but studies examining the potential effect of available therapies are missing. This study aims to investigate the overall levels of daily physical activity in patients with severe eosinophilic asthma and whether anti-interleukin-5 therapy with mepolizumab, on top of existing, maximal, and optimised asthma treatment, may improve patient's daily physical activity.
