SNPs associated withHHIPexpression have differential effects on lung function in males and females
2019
AbstractAdult lung function is highly heritable and 279 genetic loci were recently reported as associated with spirometry-based measures of lung function. Though lung development and function differ between males and females throughout life, there has been no genome-wide study to identify genetic variants with differential effects on lung function in males and females. Here, we present the first genome-wide genotype-by-sex interaction study on four lung function traits in 303,612 participants from the UK Biobank. We detected five SNPs showing genome-wide significant (P<5 × 10−8) interactions with sex on lung function, as well as 21 suggestively significant interactions (P<1 × 10−6). T…
The German COPD cohort COSYCONET: Aims, methods and descriptive analysis of the study population at baseline
2016
Abstract Background The German COPD cohort study COSYCONET (" CO PD and SY stemic consequences- CO morbidities NET work") investigates the interaction of lung disease, comorbidities and systemic inflammation. Recruitment took place from 2010 to 2013 in 31 study centers. In addition to the baseline visit, follow-up visits are scheduled at 6, 18, 36 and 54 months after baseline. The study also comprises a biobank, image bank, and includes health economic data. Here we describe the study design of COSYCONET and present baseline data of our COPD cohort. Methods Inclusion criteria were broad in order to cover a wide range of patterns of the disease. In each visit, patients undergo a large panel …
Subclinical impairment of lung function is related to mild cardiac dysfunction and manifest heart failure in the general population.
2016
Lung function impairment has previously been related to heart failure, although no overt cardiovascular or structural heart disease is present. The extent to which pulmonary function is related to subclinical left ventricular impairment in the general population remains to be investigated.15010 individuals from the general population (mean age 55±11years, 50.5% men) in the Gutenberg Health Study underwent spirometry, transthoracic echocardiography and biomarker measurement. Forced expiratory volume in 1s (FEV1) and forced vital capacity (FVC) in percent of the predicted value and FEV1/FVC ratio were associated with echocardiographic measures of cardiac structure, systolic and diastolic func…
FEV1 and FVC predict all-cause mortality independent of cardiac function - Results from the population-based Gutenberg Health Study.
2017
Abstract Background Lung function has previously been related to increased mortality. Whether pulmonary impairment is associated with an increased mortality independent of cardiac dysfunction remains unclear. Methods In 15010 individuals from the general population (age range 35–74years, 51% men) in the Gutenberg Health Study we performed spirometry and transthoracic echocardiography. N-terminal pro-B-type natriuretic peptide (Nt-proBNP) and high-sensitive troponin I (hsTnI) were measured in all individuals. 1819 individuals with pulmonary diseases were excluded from further analysis. Results The median for forced expiratory volume in 1s (FEV1) was 94.2% and for forced vital capacity (FVC) …
The Effect of Tiotropium in Symptomatic Asthma Despite Low- to Medium-Dose Inhaled Corticosteroids: A Randomized Controlled Trial.
2014
BackgroundTiotropium, a once-daily long-acting anticholinergic bronchodilator, has demonstrated efficacy in patients with asthma who were symptomatic despite treatment with medium- to high-dose inhaled corticosteroids (ICS).ObjectiveThe objective of this study was to evaluate the efficacy and safety of once-daily tiotropium Respimat (5 μg or 2.5 μg), compared with placebo Respimat, as add-on therapy to low- to medium-dose ICS for adults with symptomatic asthma.MethodsA phase III, double-blind, placebo-controlled trial was conducted (NCT01316380). Adults with symptomatic asthma receiving low- to medium-dose ICS (200-400 μg budesonide or equivalent dose) and a pre-bronchodilator forced expira…
Italian pediatric respiratory society recommendations on pediatric pulmonary function testing during COVID-19 pandemic
2020
The coronavirus disease 2019 (COVID-19) is a public health emergency of international concern caused by a newly discovered coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2). Person-toperson transmission of SARS-CoV-2 occurs primarily through close contact with an infected person, mainly occurring via respiratory droplets and after touching contaminated objects. Accordingly, pulmonary function testing (PFT) could be considered at high-risk for viral transmission due to the potential for coughing and droplet formation during PFT procedures. The most likely surfaces for possible contamination by this route are mouthpieces, proximal valves, and tubing. Also, both technic…
Development of a nomogram to estimate the quality of life in asthmatic children using the Childhood Asthma Control Test
2016
Background: Pediatric Asthma Quality of Life Questionnaire (PAQLQ) provides detailed information on QoL in asthmatic children, whereas Childhood Asthma Control Test (C-ACT) Questionnaire is the most validated instrument for asthma control. No study assessed the relationship between C-ACT and QoL in children by means of those instruments. The aim of this study was to determine whether a QoL estimation is possible using the C-ACT questionnaire in asthmatic children. Methods: Medical history, spirometry, C-ACT, and PAQLQ were assessed in 144 (60% male) outpatient asthmatic children from September 2011 to November 2014. A generalized linear model (GLM) for the prediction of PAQLQ was obtained t…
Determinants of Allergic Sensitization, Asthma and Lung Function: Results from a Cross-Sectional Study in Italian Schoolchildren
2020
Prenatal smoking exposure and early-life respiratory infections are major determinants of asthma during childhood. We investigate the factors influencing allergic sensitization (AS), asthma, and lung function in children and the balance between individual and environmental characteristics at different life stages. 1714 children aged 7&ndash
Clinical and economic consequences of switching from omalizumab to mepolizumab in uncontrolled severe eosinophilic asthma
2021
AbstractSevere asthma is burdened by frequent exacerbations and use of oral corticosteroids (OCS), which worsen patients’ health and increase healthcare spending. The aim of this study was to assess the clinical and economic impact of switching from omalizumab (OMA) to mepolizumab (MEP) in patients eligible for both biologics, but not optimally controlled by omalizumab. We retrospectively enrolled uncontrolled severe asthmatic patients who switched from OMA to MEP during the last two years. Information included blood eosinophil count, asthma control test (ACT), spirometry, serum IgE, fractional exhaled nitric oxide (FeNO), OCS intake, drugs, exacerbations/hospitalizations, visits and diagno…
Pathophysiological Factors in the Relationship between Chronological Age and Calculated Lung Age as Detected in a Screening Setting in Community-Dwel…
2016
Aim To explore the relationship between pathophysiological factors and premature lung aging in a cohort of community-dwelling subjects in a health-screening setting. Methods 16,107 pharmacy customers in Germany (5954 males, 10,153 females; mean age 59.7 years) participated in a lung function screening project by providing demographic data, including smoking status and known airway conditions and performing spirometry with a Vitalograph, a spirometry screening device. Lung age was calculated from the spirometric findings, and the difference between chronological age and calculated lung age was analyzed in its relationship to the demographic data in general linear models. Results In the overa…
