In this report, AFO prevalence is higher when the PREO criterion is applied. About 8.5% of all subjects had PREO-POSTN, whereas 3% had a PREN-POSTO spirometric pattern. In adjusted analysis, we found no difference in COPD features and outcomes between PREO-POSTN and PREN-POSTO subjects. Although both prebronchodilator and postbronchodilator spirometry are associated with chronic bronchitis, dyspnoea, exercise capacity and COPD radiographic findings, models that include postbronchodilator spirometric measures perform better than those with prebronchodilator measures to predict those outcomes. The predictive value of prebronchodilator and postbronchodilator spirometries are relatively similar for respiratory exacerbations, change in FEV1 and dyspnoea from phase 1 to phase 2 visits. Both prebronchodilator and postbronchodilator spirometry are associated with mortality, but models that include postbronchodilator spirometric measures perform better than models with prebronchodilator spirometry.

OBJECTIVE: the criteria for disease severity established by the Global Initiative for Chronic Obstructive Lung Disease are based on forced expiratory volume in I second (FEV) expressed as a percentage of the predicted value after application of a bronchodilator. This study aims to determine postbronchodilator spirometry reference values.SUBJECTS and METHODS: A cluster sample of subjects aged 40 years or over was chosen to be representative of the metropolitan areas of 5 Latin American cities (São Paulo, Mexico City, Montevideo, Santiago, and Caracas). Spirometry was performed on 5183 subjects following the recommendations of the American Thoracic Society before and after inhalation of 200 mu g of salbutamol. Multiple linear regression equations were fitted for the postbronchodilator spirometric values-FEV1, forced expiratory volume in 6 seconds (FEV6), peak expiratory flow rate, forced vital capacity (FVC), FEV1/FEV6, FEV1/FVC and forced expiratory flow between 25% and 75% of vital capacity ...

In 415 nonsmoking asthmatic children who were seen consecutively, asthma symptoms were more severe if the mother was a smoker than if she was a nonsmoker. This applied to both sexes but was more marked in boys than in girls. There were also other indications that sons were the more severely affected: the forced expiratory volume at 1 second, the forced expiratory flow rate during the middle half of the forced vital capacity, and the provocation concentration of histamine needed to result in a 20% decrease in the forced expiratory volume at 1 second were significantly decreased only in the sons, and lung function test results were significantly less in sons than in daughters of mothers who smoked. When the 415 children were stratified according to age, lung function improved significantly with increasing age in the children of nonsmokers; in children of smokers, by contrast, symptoms and lung function test results became progressively worse. As well, there was a correlation between these ...

The sensitivity and specificity of post-bronchodilator FEV1 increment at different cut-offs is shown in Table A3 in the appendix.. Discussion. This study showed that correlation between the sputum eosinophil level and bronchodilator reversibility was weak. Although COPD patients with VPBT (ΔFEV1>0.4L and >15%) had significantly higher levels of sputum eosinophils than those without, the ability of VPBT to predict sputum eosinophilia is modest (positive predictive value: 63.6%, overall accuracy: 70.1%). In contrast, levels of sputum eosinophils did not differ between groups when subjects were dichotomized according to the widely accepted criterion for PBT (ΔFEV1>0.2L and >12%),16 which was adopted in the GINA guidelines for asthma and the 2010 version of the GOLD guidelines for COPD.4,17. Current guidelines no longer consider the extent of bronchodilator reversibility to be beneficial in the diagnosis of COPD or the differential diagnosis with asthma, even though post-bronchodilator spirometry ...

1. The forced expiratory volume (FEV0·75) was measured at increasing mouth pressures in twenty-seven patients with obstructive airways disease. Attempts were made to divide the patients on clinical grounds into emphysematous, bronchitic or asthmatic categories; there was no evidence from the (FEV/mouth pressure) plots that their airways functioned differently during forced expiration.. 2. Static elastic recoil was measured in twelve patients. There was no evidence that this factor alone caused the loss of FEV in any patient.. 3. It is suggested that the use of the FEV as a test of respiratory function during the natural history of obstructive airways disease should be considered in three stages. There is an initial phase when peripheral airways disease develops with little or no alteration of the FEV. In the second phase the FEV decreases from normal values to below 1·0 litre, and at this stage is considered a sensitive indicator of peripheral airways resistance. In stage 3 the FEV is low and ...

We thank M.R. Miller for his comments on our paper regarding bronchodilator reversibility in asthma and COPD [1]. We agree that it is important to look at different ways of defining bronchodilator reversibility. In our analysis, we investigated both flow-related bronchodilator reversibility, defined by the change in forced expiratory volume in 1 s (FEV1), and volume-related bronchodilator reversibility, defined by the change in forced vital capacity. We also looked at both the change in lung function parameters expressed as percent of the baseline value and the change in FEV1 standardised by the subjects predicted value. The latter was evaluated to control for the sex, age and height dependency of lung function. The results when reversibility was expressed as percent of the predicted value (in supplementary tables E3 and E4) [1] were the same as when reversibility was expressed as percent of the baseline value. Our interpretation was therefore that, in the present study, neither flow-related ...

Little is known on the long-term validity of reference equations used in the calculation of FEV(1) and FEV(1)/FVC predicted values. This survey assessed the prevalence of chronic airflow obstruction in a population-based sample and how it is influenced by: (i) the definition of airflow obstruction; and (ii) equations used to calculate predicted values. Subjects aged 45 or more were recruited in health prevention centers, performed spirometry and fulfilled a standardized ECRHS-derived questionnaire. Previously diagnosed cases and risk factors were identified. Prevalence of airflow obstruction was calculated using: (i) ATS-GOLD definition (FEV(1)/FVC,0.70); and (ii) ERS definition (FEV(1)/FVC,lower limit of normal) with European Community for Coal and Steel (ECCS) reference equations and with predicted values derived from the presumably normal fraction of the studied population. A total of 5008 subjects (4764 adequate datasets) were studied. Prevalence of airflow obstruction was 8.71% with ...

Background. Few studies have examined the relationships between sputum inflammatory markers and subsequent annual decline in forced expiratory volume in 1 s (dFEV1). This study investigated whether indices of airway inflammation are predictors of dFEV1 in a general population-based sample.. Methods. The study, conducted from 2003 to 2005, included 120 healthy Norwegian subjects aged 40 to 70 years old. At baseline, the participants completed a self-administered respiratory questionnaire and underwent a clinical examination that included spirometry, venous blood sampling, and induced sputum examination. From 2015 to 2016, 62 (52%) participants agreed to a follow-up examination that did not include induced sputum examination. Those with a FEV1/forced vital capacity (FVC) ratio < 0.70 underwent a bronchial reversibility test. The levels of cytokines, pro-inflammatory M1 macrophage phenotypes were measured in induced sputum using bead-based multiplex analysis. The associations between cytokine ...

This study has shown for the first time that patients with moderate to severe COPD who suffered frequent exacerbations (,2.92 per year) experienced a significantly greater decline in FEV1 of 40 ml/year and in PEF of 2.9 l/min/year than patients who had infrequent exacerbations (,2.92 per year) in whom FEV1 declined by only 32 ml/year and PEF by 0.7 l/min/year. Similar differences in the decline in FEV1 were found whether or not the patient visited a physician at exacerbation. Frequent exacerbations were also associated with a faster decline in FEV1 if allowance was made for smoking status, although there was only a relatively small effect of smoking, possibly because there was only one smoker in the infrequent exacerbator group. A faster decline in the group with frequent exacerbations could be explained by less treatment of their exacerbations, but during the study we found no change over time in the probability of treatment of exacerbations with antibiotics or oral steroids in the frequent and ...

High bronchodilator reversibility in adult asthma is associated with distinct clinical characteristics. In this study, we aim to make a comparison with T-helper 2 (Th2)-related biomarkers, lung function and asthma control between asthmatic patients with high airway reversibility (HR) and low airway reversibility (LR). Patients with asthma diagnosed by pulmonologist according to Global Initiative for Asthma guidelines were recruited from the outpatient department of our hospital from August 2014 to July 2017. Patients were divided into HR and LR subgroups based on their response to bronchodilators of lung function (HR = Δforced expiratory volume in one second (FEV1) postbronchodilator ≥ 20%). Blood eosinophil count and serum IgE level, which are biomarkers of T-helper (Th)-2 phenotypes, were detected for patients. Asthma Control Test (ACT) was used to assess asthma control after the first-month initial treatment. A total of 265 patients with asthma were followed 1 month after initial treatment. HR

BACKGROUND: Little is known about the long-term outcomes of individuals with mild chronic obstructive pulmonary disease (COPD) as defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD). METHODS: A population cohort of 6671 randomly selected adults without asthma was stratified into categories of modified GOLD-defined COPD (prebronchodilator spirometry). Further stratification was based on the presence or absence of respiratory symptoms. After 11 years, associations between baseline categories of COPD and decline in forced expiratory volume in 1 s (FEV(1)), respiratory care utilisation and quality of life as measured by the SF-36 questionnaire were examined after controlling for age, sex, smoking and educational status. RESULTS: At baseline, modified GOLD criteria were met by 610 (9.1%) participants, 519 (85.1%) of whom had stage 1 COPD. At follow-up, individuals with symptomatic stage 1 COPD (n = 224) had a faster decline in FEV(1) (-9 ml/year (95% CI -13 to -5)), increased ...

Morgan et al. (2013) concluded that cystic fibrosis (CF) in children and adolescents with a high baseline forced expiratory volume (FEV1) were less likely to have a therapeutic intervention or slower rate of FEV1 decline after a single acute decline in FEV1 of 10%. This conclusion is not well supported due to the arbitrary criteria used for defining a pulmonary exacerbation, as explained below. First, only a single low FEV1 value defined an exacerbation. However, FEV1 measurements are notoriously variable from test to test; Taylor-Robinson et al.(2012) showed that the baseline fluctuations have a wide range of about 60%. FEV1 tests are sensitive to time of day, health status, mood, tiredness, lack of sleep, medical instruction, nutritional status, acute comorbidities, and other factors CFF (2011). Given that a single FEV1 assessment was used, rather than the average of repeated measurements on different days, evidence that the assessment values were technically accurate. Second, an exacerbation was

In this analysis of a large, prospective, population based cohort, lung function impairment was associated with an increased risk of having or developing CVD in adults; the highest risks were observed among those with GOLD 2 (moderate) and GOLD 3 or 4 (severe/very severe) COPD. After adjusting for multiple covariates, including age, sex, race, smoking status, diabetes, hypertension, cholesterol levels and fibrinogen levels, the relation between lung function impairment and CVD was reduced, suggesting that some of this relation may be mediated through these other factors.. Previous research suggests that systemic inflammation present in COPD leads to the increased CVD risk, and that treatment aimed at decreasing inflammation in those with COPD may decrease the development of cardiovascular disease or reduce event recurrence. Vascular inflammation may also contribute to impaired airway vascular smooth muscle relaxation in COPD. Treatment with agents that affect systemic inflammation or vascular ...

Objectives: This prospective study was conducted to evaluate the value of sonographic B-lines (previously called comet tail artifacts) in assessment of patients with bronchiectasis, and compare them with the findings of chest high-resolution computed tomography (HRCT) and pulmonary function tests (PFTs).. Methods: Ninety-one patients with clinically diagnosed bronchiectasis underwent transthoracic lung sonography for assessment of the presence of B-lines, and the distance between them. In each single positive zone the number of B-lines were counted(,5 lines ,5-15 line,15-30 line,,30 line)). These findings were compared with that of chest HRCT (type of bronchiectasis :cylindrical, varicose and cystic types) and extent of bronchiectasis in chest HRCT: one third ,two thirds, or more than two thirds of the lobe). Also B-ines were compared with PFT (forced expiratory volume in first second over forced vital capacity (FEV1/FVC), forced expiratory volume in first second (FEV1), forced expiratory flow ...

As soon as your lungs show a significant worsening in lung function, with a drop in forced expiratory volume at 1 second (FEV1) of 20% or more, the test is considered complete. You will be given an inhaled bronchodilator treatment (usually albuterol or levalbuterol) to help re-open your airways. You will then repeat the spirometry test to make sure your lungs have returned to normal. The concentration of the methacholine given at this point will be your test result. If you do not have a drop in function or symptoms, the last dose given is the result ...

Regressive models were used to search for possible major gene effects on pulmonary function in two groups of families: one ascertained through patients with chronic obstructive pulmonary disease [COPD defined as forced expiratory volume in one second (FEV1) less than 70% forced vital capacity (FVC)] …

Abstract. Background: pulmonary function can change with age for normal individuals .Spirometric measurement for the ratio of forced expiratory volume in one second (FEV1), the forced vital capacity and the ratio (FEV1/FVC) can reveal airway obstruction and the consequence change in pulmonary performance. These parameters can be different for different race /ethnic and gender.Methods: Pulmonary function test were carried out on 29normal male and 37 normal female the test parameters were FEV1 and FVC from which the ratio of FEV1/FVC %was calculated in relation to age. Iraqi average for FEV1 and FVC and FEV1/FVC % has also been obtainedResults: results of these tests reveled that the ratio of FEV1/FVC % is almost the same for individuals ages between 20-60 and a significant depression in the value of the ratio FEV1/FVC % for ages > 60 years.Conclusion: the effect may be linked with some changes in the airways in addition to the increased weakness in the muscles in the old age people.

Methods. Participants (n = 1784) with complete postbronchodilator spirometry who did not meet spirometric criteria for chronic obstructive pulmonary disease (COPD) at time of enrollment in the COPDGene study were included in this study. Subjects were classified as RSP if they had forced expiratory volume in 1 s(FEV1) to forced vital capacity (FVC) ratio , 0.7 with an FVC , 80%. Computed tomography (CT) scans were scored for the presence of DISH in accordance with the Resnick criteria. Chest CT measures of interstitial and alveolar lung disease, clinical symptoms, health surveys, and 6-min walking distance were recorded. Uni- and multivariable analyses were performed to test the association of DISH with RSP. ...

For example, your FEV1 may be 80% of predicted based on your height, weight, and race. The volume of air that can be forced out in one second after taking a deep breath, an important measure of pulmonary function. FEV1: The maximum amount of air expired in one second. How is the FEV1 test performed? FEV1 is a marker for the degree of obstruction with your asthma:1? FEV1/ FVC. Looking for the definition of FEV1? Your FEV1 value is an important part of evaluating chronic obstructive pulmonary disease (COPD) and monitoring progression of the condition. For well over thirty years my lab has used an FEV1/FVC ratio of 95% of predicted as the cutoff for normalcy. FVC is the … Forced vital capacity (FVC) is the total amount of air exhaled during the FEV test. FEV1 and FVC are tests used in the diagnosis of various lung diseases. This means that over time, your COPD will typically worsen. This percentage can help stage COPD. To make the comparison between your FEV1 score and your predicted value, your ...

COPD is a leading cause of morbidity and mortality worldwide. Comorbid diseases are an important factor in the prognosis and functional capabilities of COPD patients. There is a relationship between cardiac comorbidity and COPD exacerbation frequency within COPD patients. The main objective of this study is to compare the rate of moderate-severe COPD exacerbations in patients of all COPD severities with and without cardiovascular diseases. Secondary objectives will characterize the prevalence, severity and incidence over time of comorbidities and explore the relationships between comorbidities and rate of COPD exacerbations, force expiratory volume in 1 second (FEV1) decline and quality of life. This will be a prospective, observational, non-drug interventional, non-randomized study that will be carried out in up to 8 European countries. All patients will be enrolled by GP outpatient clinics and data will be collected over 4 visits (screening [-3 months], baseline, 12 months post baseline 24 ...

This four-week randomized, double-blind, placebo-controlled dose-ranging Phase 2b trial enrolled a total of 416 patients with moderate-to-severe symptomatic COPD at 46 sites in the U.S. The trial is designed to evaluate the safety and efficacy of nebulized ensifentrine as an add-on to inhaled tiotropium, a long acting anti-muscarinic (LAMA) commonly used to treat patients with COPD.. Patients will receive nebulized ensifentrine at four dose levels: 0.375 mg, 0.75 mg, 1.5 mg and 3.0 mg or placebo twice daily for four weeks. The trials primary endpoint is improvement in lung function with ensifentrine after four weeks of treatment, as measured by peak forced expiratory volume in one second (FEV1), a standard measure of lung function. Key additional endpoints include other lung function measures, as well as measurements of symptoms associated with COPD and quality of life outcomes. For further information on this clinical trial, please visit ClinicalTrials.gov, NCT03937479.. Verona Pharma is ...

In the past three decades, mortality from chronic obstructive pulmonary disease (COPD) has risen dramatically, making COPD the fourth leading cause of death in 2000.1 Compared with people with normal lung function, subjects with severe COPD (forced expiratory volume in 1 second [FEV1] ,50% predicted) followed for 22 years as part of the National Health and Nutrition Examination Survey (NHANES I) had a 2.7-fold increased risk of death (95% CI 2.1 to 3.5) in an adjusted analysis.2 This trend is apparent in men and women, more prominent in black Americans, and clearly related to cigarette smoking. For the first time, in 2000 more women than men died of COPD in the U.S.1 Admissions to ICUs for exacerbations of COPD account for a substantial portion of bed-days,3 since these patients often require prolonged ventilatory support. In surgical ICUs, COPD is an important problem as well, since it is one of the more common reasons for a prolonged postoperative recovery. An approach to this disease is an ...

Sir,I read with interest the article on hospital doctors assessment of baseline spirometry, by Stephenson and colleagues, in a recent issue of this journal.1 It is indeed a matter of great concern that only 12% of the respondents could accurately interpret all the five vitalographs given to them. What is still more disturbing is the fact that the correct interpretation for the third vitalograph was considered as combined defect. This vitalograph, in a 77-year-old man, shows a mild reduction in forced vital capacity (FVC) (63% of predicted) and a severe reduction in both the forced expiratory volume in the first second (FEV1) and the FEV1/FVC ratio (30% and 38%, respectively). The volume-time curve provided is also flattened, indicating diminished expiratory flow. All these features are consistent with a obstructive rather than a combined defect. As per standard guidelines on interpretation of spirometry,2 an obstructive defect should be diagnosed when the decrease in FEV1 is out of proportion ...

The objective of this study was to determine whether or not exposure to a low level of nitrogen dioxide could cause cardio-respiratory effects in health elderly people. Ten healthy subjects (67-85 years of age) were exposed to clean air and 300 ppb nitrogen dioxide for 30 minutes while at rest. Pulmonary function measurements assessed were forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV 25-75 and peak flow (PEF). Cardiac function measurements assessed were systolic blood pressure, diastolic blood pressure, heart rate, arterial oxygen saturation and heart rate variability (HRV). Exhaled nitric oxide (NO) and carbon monoxide (CO) concentrations were measured as airway inflammation markers. Baseline measurements were conducted before exposure followed by two post exposures, 1hour after (PE1) and 18 hours after (PE2) exposure.. Paired t-tests were used to compare all the health measurements between air and NO2 exposure. Results of this study showed no ...

Preliminary investigations from our own research group showed that lung function parameters (FEV1, the FEV1/FVC ratio and a moderate to severe hyperresponsiveness to methacholine challenge were risk factors of asthma exacerbations (OR 11.3). In the present study, these parameters will be evaluated in prospective design.. One hundred children will be included in the study. Baseline parameters will be collected in a healthy interval (visit 1), then the children will be followed up for 1 year. If the patients fulfill the criteria for an exacerbation the children will present in our department. We expect that 44% of the children have an exacerbation. All children will present at a second visit after one year (visit 2). ...

This study included 23 patients with RP who underwent both CT and PFTs. In each patient, the mean lung density (MLD) was obtained by averaging CT attenuation of the lung parenchyma on both inspiratory and expiratory CT. The ratio of expiratory MLD to inspiratory MLD (E/I ratio) was also calculated. Correlations between those quantitative CT measurements and the results of PFTs were evaluated using Spearman rank correlation. Results: The expiratory MLD and E/I ratio were significantly correlated with forced expiratory volume in 1 second (FEV1) %predicted, ratio of FEV1 to FVC (FEV1/FVC), and the mid expiratory phase of forc ...

Lung function decline in COPD Claudio Tantucci, Denise ModinaUnit of Respiratory Medicine, Department of Medical and Surgical Sciences, University of Brescia, Brescia, ItalyAbstract: The landmark study of Fletcher and Peto on the natural history of tobacco smoke-related chronic airflow obstruction suggested that decline in the forced expiratory volume in the first second (FEV1) in chronic obstructive pulmonary disease (COPD) is slow at the beginning, becoming faster with more advanced disease. The present authors reviewed spirometric data of COPD patients included in the placebo arms of recent clinical trials to assess the lung function decline of each stage, defined according to the severity of airflow obstruction as proposed by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. In large COPD populations the mean rate of FEV1 decline in GOLD stages II and III is between 47 and 79 mL/year and 56 and 59 mL/year, respectively, and lower than 35 mL/year in GOLD stage IV.

Chronic obstructive pulmonary disease (COPD), a.k.a. chronic obstructive lung disease (COLD), chronic obstructive airway disease (COAD), chronic airflow limitation (CAL) and chronic obstructive respiratory disease (CORD), is the occurrence of chronic bronchitis and emphysema together. This pair work together to narrow the airways of the lungs leading to breathing problems. The disease is under-diagnosed and under-treated. Smoking tobacco smoking is one of the major causes as is exposure to smoke from coal and wood used as domestic fuels.. In contrast to asthma, breathing problems in COPD are poorly reversible even with powerful bronchodilators and the condition worsens over time. BusinessWire reports that the market for COPD drugs will increase from approximately $8.3 billion in 2010 to more than $13.4 billion by 2020. A lateral part of the market is, of course, influenza vaccination. Most healthcare practitioners recommend that COPD patients receive an annual flu jab. Among the companies hoping ...

Clinical trial for COPD (Chronic Obstructive Pulmonary Disease) , A Phase 4 clinical study for patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD) who experience COPD exacerbations.

Background Patients with chronic obstructive pulmonary disease (COPD) have few options for treatment. The effi cacy and safety of the phosphodiesterase-4 inhibitor rofl umilast have been investigated in studies of patients with moderate-to-severe COPD, but not in those concomitantly treated with longacting inhaled bronchodilators. The eff ect of rofl umilast on lung function in patients with COPD that is moderate to severe who are already being treated with salmeterol or tiotropium was investigated. Methods In two double-blind, multicentre studies done in an outpatient setting, after a 4-week run-in, patients older than 40 years with moderate-to-severe COPD were randomly assigned to oral rofl umilast 500 μg or placebo once a day for 24 weeks, in addition to salmeterol (M2-127 study) or tiotropium (M2-128 study). The primary endpoint was change in prebronchodilator forced expiratory volume in 1 s (FEV1). Analysis was by intention to treat. The studies are registered with ClinicalTrials.gov, ...

This study was designed to establish normative data for individuals 18-22 years old using oscillometry by comparing the values to spirometry. Oscillometry is a less invasive procedure for respiratory testing than spirometry testing. One hundred and forty-two participants completed self-assessment questionnaires, along with body composition measurements and at least three trials each of oscillometry and spirometry testing. The results of the study conclude that no normative data could be established in this study over all resistance (R) and reactance (X) frequencies for males and females. The secondary goal of this study was to examine the effects of smoking, physical activity, and weight on forced expiratory volume (FEV1). Smoking and weight had a significant effect on FEV1 while there was no significance to physical activity and FEV1 but a trend was found. In conclusion, more testing needs to be conducted to create normative data for 18-22 year olds. This will assist professionals in diagnosing

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterized by an incompletely reversible limitation in airflow. A physiological variable--the forced expiratory volume in one second (FEV1)--is often used to grade the severity of COPD. However, patients with COPD have systemic manifestations that are not reflected by the FEV1. We hypothesized that a multidimensional grading system that assessed the respiratory and systemic expressions of COPD would better categorize and predict outcome in these patients.. METHODS: We first evaluated 207 patients and found that four factors predicted the risk of death in this cohort: the body-mass index (B), the degree of airflow obstruction (O) and dyspnea (D), and exercise capacity (E), measured by the six-minute-walk test. We used these variables to construct the BODE index, a multidimensional 10-point scale in which higher scores indicate a higher risk of death. We then prospectively validated the index in a cohort of 625 patients, with death ...

Chronic obstructive pulmonary disease. Other risk factors may include: 1. indoor air pollution (such as solid fuel used for cooking and heating) 2. outdoor air pollution 3. occupational dusts and chemicals (such as vapours, irritants, and fumes) 4. frequent lower respiratory infections during childhood.Many cases of COPD are preventable. Early in the disease, people with COPD may feel short of breath when they exercise. Significant heterogeneity of clinical presentation and disease progression exists within chronic obstructive pulmonary disease (COPD).

Precision medicine is a patient-specific approach that integrates all relevant clinical, genetic and biological information in order to optimise the therapeutic benefit relative to the possibility of side-effects for each individual. Recent clinical trials have shown that higher blood eosinophil counts are associated with a greater efficacy of inhaled corticosteroids (ICSs) in chronic obstructive pulmonary disease (COPD) patients. Blood eosinophil counts are a biomarker with potential to be used in clinical practice, to help target ICS treatment with more precision in COPD patients with a history of exacerbations despite appropriate bronchodilator treatment.The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 pharmacological treatment algorithms, based on the ABCD assessment, can be applied relatively easily to treatment-naive individuals at initial presentation. However, their use is more problematic during follow-up in patients who are already on maintenance treatment. There is a

AstraZeneca today announced top-line results from the AERISTO Phase IIIb trial for Bevespi Aerosphere (glycopyrronium/formoterol fumarate) in patients with moderate to very severe chronic obstructive pulmonary disease (COPD). In the trial, Bevespi Aerosphere demonstrated non-inferiority to umeclidinium/vilanterol on peak forced expiratory volume in one second (FEV1) but did not demonstrate superiority on peak FEV1 or non-inferiority on trough FEV1.. Dr Colin Reisner, Head of Respiratory, Global Medicines Development, said: The efficacy and safety of Bevespi Aerosphere has been established by the Phase III PINNACLE trial programme involving more than 5,000 patients. The performance of Bevespi Aerosphere in AERISTO is inconsistent with previous data. A full analysis is underway to understand and characterise these findings and will be presented at a forthcoming medical meeting.. The 24-week AERISTO Phase IIIb trial was a randomised, double-blinded, double-dummy, multicentre, parallel-group trial ...

Genome-wide association studies (GWAS) have identified numerous loci influencing cross-sectional lung function, but less is known about genes influencing longitudinal change in lung function.We performed GWAS of the rate of change in forced expiratory volume in the first second (FEV1) in 14 longitudinal, population-based cohort studies comprising 27,249 adults of European ancestry using linear mixed effects model and combined cohort-specific results using fixed effect meta-analysis to identify novel genetic loci associated with longitudinal change in lung function. Gene expression analyses were subsequently performed for identified genetic loci. As a secondary aim, we estimated the mean rate of decline in FEV1 by smoking pattern, irrespective of genotypes, across these 14 studies using meta-analysis.The overall meta-analysis produced suggestive evidence for association at the novel IL16/STARD5/TMC3 locus on chromosome 15 (P = 5.71 × 10(-7)). In addition, meta-analysis using the five cohorts ...

BACKGROUND: Asthma is a common chronic disease affecting patients health status and quality of life. Although recent guidelines focus on asthma control, asthma remains poorly controlled in many patients even under specialist care. Asthma Control Test™ (ACT) is a short, simple, patient-based tool that provides consistent assessment of asthma.OBJECTIVE: The aim of this study was to estimate the relationship of ACT with objective measures of lung function and inflammation such as forced expiratory volume in 1st second (FEV(1)) and exhaled nitric oxide (FeNO) in outpatients admitted for initial diagnosis of asthma and at follow-up.METHODS: One hundred and sixty (104 women and 56 men, mean age 39.7 ± 16.6 years) asthmatic patients with newly diagnosed asthma were included in the study. Patients completed the ACT questionnaire and underwent a detailed clinical examination, FeNO measurement, and prebronchodilator spirometry before (visit 1) and 4-12 weeks after initiation of treatment (visit ...

Club cell secretory protein (CC-16) is a sensitive biomarker of airways epithelium integrity. It has gained interest as a biological marker in chronic lung diseases because of its presumed relationship to inflammation. Little is known about the association between CC-16 serum level and asthma, lung function and airway responsiveness (AR). Serum CC-16 level was determined by latex immunoassay in 1298 participants from the French Epidemiological case-control and family-based study on Genetics and Environment of Asthma (EGEA) (mean age 43 years; 49% men, 38% with asthma). Pre-bronchodilator lung function (forced expiratory volume in 1 s (FEV1 ), forced vital capacity (FVC) and FEV1 /FVC) and degree of AR, expressed as a function of the dose-response slope to methacholine test were measured. Standardized residuals CC-16 z-scores were obtained by regressing CC-16 level on the glomerular filtration rate. CC-16 z-scores were correlated with asthma, lung function and AR in participants with and without asthma.

BACKGROUND: Low lung function, measured using spirometry, has been associated with mortality from cardiovascular disease, but whether this is explained by airflow obstruction or restriction is a question that remains unanswered. OBJECTIVES: To assess the association of total lung capacity (TLC), forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) with several cardio-metabolic and inflammatory markers. METHODS: In the follow up of the Burden of Lung Disease (BOLD) study in London, acceptable post-bronchodilator spirometric, pulse rate, pulse wave velocity and blood pressure data were obtained from 108 participants. Blood samples for measurement of cardio-metabolic and inflammatory markers were also collected from these participants. Association of lung function and volume with the different biomarkers was examined in multivariable linear regression models adjusted for potential confounders. RESULTS: Following adjustment for age, sex, height, and ethnicity, TLC (adjusted coefficient =

In an important breakthrough, researchers have found IL-4 antagonist dupilumab to be effective in preventing asthma exacerbations in patients suffering from moderate to severe asthma. The research was led by Sally Wenzel from the University of Pittsburgh and has been reported online in the New England Journal of Medicine.. For their research, Wenzel and colleagues chose patients with moderate to severe asthma with eosinophil count ≥300 cells/mL and a sputum eosinophil count of ≥3%. All the participants were suffering from asthma for at least one year and had a forced expiratory volume at 1 second (FEV1) ≥50% of predicted. The patients were administered either dupilumab (300 mg) or a placebo simultaneously once a week for 12 weeks or until an exacerbation of asthma occurred. Patients also received fluticasone and salmeterol twice a day for 4 weeks. In patients who were already on steroids, the dose of steroid was tapered and finally discontinued from 6th to 9th week.. It was seen that 87% ...

AIM: This paper is a report of a study to describe the essential structure of the lived experience of living with severe chronic obstructive pulmonary disease (COPD) during the palliative phase of the disease. BACKGROUND: Chronic obstructive pulmonary disease is one of the most common diseases throughout the world. Shortness of breath, fatigue and cough are the most troublesome symptoms, and living with COPD often imposes limitations on daily living. The disease has a great impact on quality of life and affects the extent to which people can be active in daily life. METHODS: We conducted qualitative interviews of eight people with COPD and collected data over a 2-month period in 2003. Our patients were recruited from two pulmonary disease clinics in West Sweden. We used a phenomenological methodology to analyse the interviews. FINDINGS: Daily life for people with COPD is affected in several different ways. The patients described how their physical limitations forced them to refrain from ...

Background: The importance of identifying chronic obstructive pulmonary disease (COPD) at an early stage is recognised. Improved and easily accessible identification of individuals at risk of COPD in primary care is needed to select patients for spirometry more accurately. Aims: To explore whether use of a mini-spirometer can predict a diagnosis of COPD in patients at risk of COPD in primary care, and to assess its cost-effectiveness in detecting patients with COPD. Methods: Primary care patients aged 45-85 years with a smoking history of ,= 15 pack-years were selected. Data were collected on the Clinical COPD Questionnaire (CCQ), Medical Research Council (MRC) dyspnoea scale and smoking habits. Lung function (forced expiratory volume in 1 and 6 s; FEV1 and FEV6, respectively) was measured by mini-spirometer (copd-6), followed by diagnostic standard spirometry (COPD diagnosis post-bronchodilation ratio of FEV1 to forced vital capacity (FVC) ,0.7). Time consumed was recorded. Univariate logistic ...

Exploration A spirometer is an apparatus often used in the medical field to find the cause of shortness of breath. A spirometer can rule out lung diseases like asthma, bronchitis, and emphysema. A spirometer can measure forced vital capacity. Forced vital capacity is the amount of air exhaled during a forced breath. Explore what factors affect forced vital capacity. Objective

Computerised Spirometry measures the forced vital capacity, forced expiratory volume in one second, and many more lung parameters including your lung age. It helps us in differentiating between obstructive and restrictive pattern of your disease. Different types of obstructive airway diseases like asthma copd can be easily picked by this investigation. A very useful tool used in our clinic for diagnosing as well as monitoring the progress and prognosis.. What is spirometry?. Spirometry is a test used for lung conditions, such as COPD* or asthma. It is a simple breathing test that measures the amount of air a person can blow out of the lungs (volume). It also measures how fast he or she can blow it out (flow). It is one of the best and most common lung function tests. Spirometry is often done in your healthcare providers office or in a clinic. Spirometry can detect COPD before symptoms become severe. Based on this test, your provider can tell if you have COPD and, if so, how severe it is.. What ...

Genome-wide association studies have identified numerous genetic loci for spirometic measures of pulmonary function, forced expiratory volume in one second (FEV1), and its ratio to forced vital capacity (FEV1/FVC). Given that cigarette smoking adversely affects pulmonary function, we conducted genome-wide joint meta-analyses (JMA) of single nucleotide polymorphism (SNP) and SNP-by-smoking (ever-smoking or pack-years) associations on FEV1 and FEV1/FVC across 19 studies (total N = 50,047). We identified three novel loci not previously associated with pulmonary function.

Chronic Obstructive Pulmonary Disease (COPD) is defined with spirometry and is characterised by persistent airflow limitation with an FEV1/FVC ratio of |0.7. An overview of the effect of COPD on severe asthma outcomes is provided.

The Scottish Medicines Consortium (SMC) has issued its monthly advice on new medicines.. Roflumilast (Daxas®) has been rejected as an add on to bronchodilator treatment in severe chronic obstructive pulmonary disease (COPD) (forced expiratory volume in 1 second post-bronchodilator ,50% predicted) associated with chronic bronchitis in adult patients with a history of frequent exacerbations. The manufacturer did not present a sufficiently robust economic analysis.. Four combined oral contraceptive pills (Rigevidon®, Gedarel®, Millinette® and TriRegol®) were all accepted for use in patients where these products would provide an appropriate form of contraception. They provide an alternative to the existing preparations at a lower cost.. Action: Clinicians should be aware of the recommendations of the SMC. Routine use of rejected and restricted medicines should be avoided.. ...

Data from the Tucson epidemiological study of airways obstructive disease on smoking of non-tobacco cigarettes such as marijuana were analysed to determine the effect of such smoking on respiratory symptoms and pulmonary function. Among adults aged under 40, 14% had smoked non-tobacco cigarettes at some time and 9% were current users. The prevalence of respiratory symptoms was increased in smokers of non-tobacco cigarettes. After tobacco smoking had been controlled for men who smoked non-tobacco cigarettes showed significant decreases in expiratory flow rates at low lung volumes and in the ratio of the forced expiratory volume in one second to the vital capacity. This effect on pulmonary function in male non-tobacco cigarette smokers was greater than the effect of tobacco cigarette smoking. These data suggest that non-tobacco cigarette smoking may be an important risk factor in young adults with respiratory symptoms or evidence of airways obstruction. ...

OBJECTIVES: Case finding is proposed as an important component of the forthcoming English National Clinical Strategy for chronic obstructive pulmonary disease (COPD) because of accepted widespread underdiagnosis worldwide. However the best method of identification is not known. The extent of undiagnosed clinically significant COPD in England is described and the effectiveness of an active compared with an opportunistic approach to case finding is evaluated. METHODS: A cross-sectional analysis was carried out using using Health Survey for England (HSE) 1995-1996 data supplemented with published literature. A model comparing an active approach (mailed questionnaires plus opportunistic identification) with an opportunistic-only approach of case finding among ever smokers aged 40-79 years was evaluated. There were 20 496 participants aged |or=30 years with valid lung function measurements. The main outcome measure was undiagnosed clinically significant COPD (any respiratory symptom with both forced

Saw my doctor again recently because I needed another prescription for my antidepressants. She wanted to know if I had gone for the chest x-ray she wanted me to have. I havent.. Last time I saw her it was because of a nasty cough I have and she prescribed ventolin. She said my airways are probably inflamed and irritated and that is causing the cough but she wants me to have the x-ray to rule out any growths that could be causing it. She said I most likely have COPD (Chronic Obstructive Pulmonary Disease), also known as Chronic Obstructive Lung Disease (COLD), but I need to have the x-ray and undergo some breathing tests to find out for sure.. I didnt have the x-ray because I dont want to know if I have lung cancer. There is no point knowing because I have already decided I will not have treatment if I develop cancer.. The doctor was gentle with me and said it isnt so much cancer but the other illnesses that she was concerned about. Untreated COPD progresses faster, she said, because inflamed ...

A diagnosis of asthma begins with the recognition of a characteristic pattern of respiratory symptoms and signs. In many patients this pattern will have emerged during childhood. However, a diagnosis later in life is not uncommon as onset may occur at any age and asthma may remit and recur during adulthood. To diagnose asthma, the patients clinical history is combined with an examination and documented evidence of variable airflow limitation.1 A therapeutic response to an inhaled bronchodilator and/or an ICS can be helpful, however, an increase in forced expiratory volume in one second (FEV1) ≥ 12% and ≥ 200 mL from baseline following bronchodilation is no longer required for a diagnosis of asthma.1 This is because most people with asthma will not exhibit this degree of reversibility at one assessment and reversibility is also seen in those with normal airway function as well as patients with chronic obstructive pulmonary disease (COPD).1 A pragmatic approach is to correlate the degree of ...
