PURPOSE: Recent studies propose TH2-mediated inflammation in patients with asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS). However, little is known about whether fractional exhaled nitric oxide (FeNO) differs between patients with ACOS and those with COPD alone. To address this knowledge gap, a nationally representative sample was analyzed to determine the difference in FeNO levels between patients with ACOS and those with COPD alone in the US population. PATIENTS AND METHODS: This is a cross-sectional analysis of the National Health and Nutrition Examination Survey from 2007 through 2012...

BACKGROUND: The clinical phenotypes and underlying mechanisms of asthma-COPD overlap syndrome (ACOS) remain elusive. This study aimed to investigate a comparison of COPD patients with and without ACOS, focusing on inflammatory biomarkers, in an outpatient COPD cohort. METHODS: We conducted a cross-sectional study analyzing prospectively collected data from the Ishinomaki COPD Network registry. All participants were diagnosed with COPD, confirmed by using spirometry, and were aged 40-90 years and former smokers...

BACKGROUND AND OBJECTIVE: Post-mortem and computed tomography (CT) studies indicated that emphysema is a feature of COPD even in the 'blue bloater/chronic bronchitis' type. We aim to test the hypothesis that the non-emphysematous patients are distinct from the main body of COPD and are more akin to asthmatic patients. METHODS: We studied 54 patients with COPD. Emphysema was measured by Goddard's visual scoring of CT scan and the carbon monoxide transfer coefficient (KCO)...

BACKGROUND: Inhalation devices represent per sé critical factors because they can affect the therapeutic outcomes independently of the drug used. The role of patients' usability and preference (PUP) for Dry Powder Inhalers (DPIs) is high indeed because they can influence the extent of the adherence to treatment and the therapeutic outcomes. Aim of the study was to assess and compare the PUP of three different DPIs in out-patients with persistent airflow limitation due to asthma or COPD...

BACKGROUND: Adherence with asthma medications is less than optimal, measuring approximately 30-50%. Several factors have been shown to contribute to medication non-adherence including low-socioeconomic status, low literacy, medication cost, access to care, and language barriers. Community Health Clinic Ole has attempted to reduce medication adherence barriers associated with cost, access to care, and language by 1) allowing medications to be obtained from the clinic at a reduced cost via the 340B drug pricing program and patient assistance programs, and 2) providing one-on-one consultations from bilingual Spanish-speaking clinicians...

BACKGROUND: Autoimmune involvement in the pathogenesis of asthma and chronic obstructive pulmonary disease (COPD) has been proposed, and autoantibodies are a hallmark of autoimmunity. This study aimed to compare the autoantibody profiles of asthma and COPD, and the relationship between autoantibodies and features of these diseases. METHODS: We recruited 110 asthma patients and 92 COPD patients for a prospective study. Six autoantibody types were evaluated: antinuclear antibody, anti-cytoplasmic antibodies, rheumatoid factor, anti-cyclic citrullinated peptide antibody, myeloperoxidase-anti-neutrophil cytoplasmic autoantibody (MPO-ANCA) and proteinase 3-ANCA...

RATIONALE: Low maximally attained lung function increases the risk of chronic obstructive pulmonary disease irrespective of the subsequent rate of lung function decline. OBJECTIVES: We aimed to determine if there were individuals with a distinct, persistently low lung function trajectory in the CRS (Tucson Children's Respiratory Study). METHODS: The CRS, an ongoing birth cohort study, enrolled 1,246 participants between 1980 and 1984. Latent class linear mixed effects modeling of the ratio of FEV1 to FVC was used to identify distinct lung function trajectories among participants with two or more spirometry measurements between ages 11 and 32 years...

BACKGROUND: Recent data have demonstrated that long-lived memory T cells are present in the human lung and can play significant roles in the pathogenesis of specific allergic and autoimmune diseases. However, most evidence has been obtained from mouse studies, and the potential roles of memory T cells in human allergic diseases, such as asthma, remain largely unknown. METHODS: Thirty-three asthmatics, 26 chronic obstructive pulmonary disease (COPD) patients, and 22 healthy volunteers were enrolled in this study...

BACKGROUND: Poor adherence to inhaled therapy is common in patients with asthma and COPD. An inhaler selection based on patients' preference could be beneficial to adherence and treatment effectiveness. Properly designed questionnaires can assess patients' satisfaction with their medication devices. The aim of this study was to estimate, using the Feeling of Satisfaction with Inhaler (FSI-10) questionnaire, the ease of use and satisfaction of patients regarding three different marketed dry powder inhalers (DPIs): Diskus(®) (DK), Elpenhaler(®) (EH), and Turbuhaler(®) (TH)...

BACKGROUND: Various studies have indicated that glucocorticoid supplementation during cardiopulmonary resuscitation (CPR), in conjunction with vasopressors, may improve outcomes in instances of cardiac arrest. However, further population-based analysis is warranted with respect to resuscitative and long-term survival benefits conferred by administering glucocorticoids in this setting. METHODS: A total of 145,644 adult patients who experienced non-traumatic, cardiac arrest occurred at emergency room during years 2004-2011 were selected for study from the Taiwan National Health Insurance Research database...

BACKGROUND: Airflow obstruction, which encompasses several phenotypes, is common among HIV-infected individuals. Obesity and adipose-related inflammation are associated with both COPD (fixed airflow obstruction) and asthma (reversible airflow obstruction) in HIV-uninfected persons, but the relationship to airway inflammation and airflow obstruction in HIV-infected persons is unknown. The objective of this study was to determine if adiposity and adipose-associated inflammation are associated with airway obstruction phenotypes in HIV-infected persons...

BACKGROUND: Elevated plasma concentrations of the endogenous nitric oxide synthase (NOS) inhibitor asymmetric dimethylarginine (ADMA) have been observed in respiratory conditions such as asthma and cystic fibrosis. Since oxidative stress has been shown to increase the activity of arginine methylating enzymes, hence increased ADMA synthesis, and to reduce ADMA degrading enzymes, hence increased ADMA concentrations, we assessed methylated arginines concentrations in chronic obstructive pulmonary disease (COPD), a disease characterized by increased oxidative stress...

BACKGROUND: In rheumatoid arthritis-associated interstitial lung disease (RA-ILD), occurring in 10 % of patients with patients with RA, usual interstitial pattern (UIP) has shown to associate with poor prognosis but more detailed data about the course of the disease in different subtypes is limited. Our aim was to compare the disease course of patients with RA-ILD categorized into either UIP or other types of ILDs. METHODS: Clinical and radiological information of 59 patients with RA-ILD were re-assessed and re-classified into UIP or non-UIP groups, followed by a between-group comparison of demographic data, lung function, survival, cause of death and comorbidities...

BACKGROUND: Overuse of short-acting beta-agonists (SABA) is described in asthma, but little is known about overuse of SABA in chronic obstructive pulmonary disease (COPD). METHODS: Prospective 3-month cohort study of patients with moderate-to-severe COPD who were provided a portable electronic inhaler sensor to monitor daily SABA use. Subjects wore a pedometer for 3 seven-day periods and were asked to complete a daily diary of symptoms and inhaler use. Overuse was defined as >8 actuations of their SABA per day while clinically stable...
