Prevalence of Severe Asthma in Spanish Hospitals

Asthma is a chronic disease. Prevalence of asthma in 2014 among Spanish population was 5%, of which 10% were diagnosed with severe asthma. According to Spanish National Guideline for the Management of Asthma (GEMA) 4.1 criteria, asthma can be classified according to its severity (intermittent, mild persistent, moderate persistent or ...

RAPP-children Rhinitis & Asthma in Patient Perspective: Development and Validation of a Questionnaire for Quality of Life Evaluation in Children With Asthma and Allergic Rhinitis

This observational study aims at developing and validating a simple questionnaire to be routinely applied in the clinical practice, for the evaluation of the quality of life in children with concomitant asthma and allergic rhinitis. The study consists of two phases: Phase 1: Development of the RAPP-children questionnaire starting from ...

Vitamin C Supplementation to Pregnant Smokers: Follow-up of 2 Randomized Trials Plus Changes in DNA Methylation

In a randomized clinical trial (RCT) published in JAMA, the investigators have provided evidence that vitamin C supplementation (500 mg daily during pregnancy) ameliorates the effects of maternal smoking during pregnancy on offspring lung function and subsequent incidence of wheeze by 48% through 1 year of age. the investigators are ...

The Genetics of Severe Asthma in Children

Our primary outcome measure is the development of a near fatal asthma exacerbation. Secondary outcome measures will include the duration of continuously nebulized ADR2 agonist therapy and the duration of IV ADR2 agonist therapy. Children will be stratified by ADR2 genotype at amino acid position 16 and outcomes compared. We ...

Phase N/A

BIOmarkers in Severe AsthMa Patients on Omalizumab Treatment

Anti-IgE (omalizumab) has been shown to be an effective add-on therapy for patients with allergic severe asthma. In this observational study patients aged over 18 year with uncontrolled severe persistent asthma are selected for add-on therapy with omalizumab. Patients were on high dose of ICS and had a documented history ...

Phase N/A

TGF-(Beta) and Susceptibility to RSV

This is a cross-sectional, controlled study designed to investigate whether Transforming Growth Factor-beta (TGF-beta) mediates increased asthmatic epithelial susceptibility to respiratory syncytial virus (RSV) infection by examining responses to RSV infection in epithelial cells cultured from asthmatic and non-asthmatic participants. Non-smoking healthy adults and mild asthmatics, aged 18-60 years old, ...

Longitudinal Observational Study in Prematurely Born Preschool Children: Assessment of Lung Function Parameters

The PRE-AR project is a longitudinal observational study. The primary objective is the assessment of lung function parameters in late preterm preschool children. Pulmonary function tests will be performed.

Phase N/A

Genetics of the Early and Late Response to Allergen Challenge

Asthmatic and/or allergic rhinitis ('hay fever') individuals respond differently, but reproducibly, to allergen challenge. Some individuals develop an isolated early response while others also go on to develop a late response. In asthmatic individuals, airway narrowing represents the early phase of the asthmatic response to airway challenge; early phase onset ...

Phase N/A

A Prospective Observational Study of Biopredictors of Bronchial Thermoplasty Response in Patients With Severe Refractory Asthma (BTR Study)

Primary Aim To assess the relationship between baseline clinical, physiologic, biologic and imaging markers and response to bronchial thermoplasty, defined by improvement in asthma quality of life, in patients with severe refractory asthma. Secondary Aims To assess the relationship between baseline clinical, physiologic, biologic and imaging markers and response to ...

Phase N/A

Vaccination Responses in Young and Older Adults

The primary investigation involves integrative multi-omics monitoring of individuals following their pneumonia vaccination over twelve time points. Genomic sequencing will be used to evaluate the volunteer's genomic risks based on variants with known disease association. Full transcriptome (via RNA-Sequencing), proteome and metabolome profiling (via mass spectrometry) will be performed per ...
