COPD is a multifactorial disease caused by environmental determinants as well as genetic risk factors. The prevalence and mortality of COPD continue to increase, and underdiagnosis of COPD remains a critical issue. Previous reports investigated promising microRNAs (miRNAs) to reveal the molecular mechanism for the development of COPD; however, diagnostic and therapeutic markers for COPD have not yet been found. For this study, 20 representative COPD patients were separated into four groups based on increasing severity (A, B, C, and D) and compared to six healthy controls...

OBJECTIVE: To analyze and compare lung function of obese and healthy, normal-weight children and adolescents, without asthma, through spirometry and volumetric capnography. METHODS: Cross-sectional study including 77 subjects (38 obese) aged 5-17 years. All subjects underwent spirometry and volumetric capnography. The evaluations were repeated in obese subjects after the use of a bronchodilator. RESULTS: At the spirometry assessment, obese individuals, when compared with the control group, showed lower values of forced expiratory volume in the first second by forced vital capacity (FEV1/FVC) and expiratory flows at 75% and between 25 and 75% of the FVC (p<0...

Clenbuterol (Broncodil and trade) is a direct-acting sympathomimetic agent with mainly beta-adrenergic activity and a selective action on β2 receptors (a β2 agonist). It has properties similar to those of salbutamol. It is used as a bronchodilator in the management of reversible airways obstruction, as in asthma and in certain patients with chronic obstructive pulmonary disease. The uses, applications, and the synthetic pathways of this drug are outlined. Physical characteristics including: ionization constant, solubility, X-ray powder diffraction pattern, thermal methods of analysis, UV spectrum, IR spectrum, mass spectrum are all produced...

BACKGROUND: Asthma-COPD overlap syndrome (ACOS) prevalence varies depending on the studied population and definition criteria. The prevalence and clinical characteristics of ACOS in an at-risk COPD primary care population from Latin America was assessed. METHODS: Patients ≥40 years, current/ex-smokers and/or exposed to biomass, attending routine primary care visits completed a questionnaire and performed spirometry. COPD was defined as post-bronchodilator forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC) < 0...

INTRODUCTION: Asthma control includes the control of symptoms and future risk. We sought to evaluate the usefulness of the degree of spirometric reversibility of the forced expiratory volume in one second (FEV1) as the target parameter of control. METHODOLOGY: Patients with bronchial asthma were followed up for one year. The clinical, functional, inflammatory and control parameters of the asthma were collected. The area under the curve (AUC) was estimated to establish the cutoff point of the post-bronchodilator FEV1 reversibility in relation to non-control asthma...

Sputum basophil numbers are increased in allergic asthmatics, but it is unclear what role airway basophils play in "TH2-low" asthma phenotypes. Using flow cytometry we found that basophils were significantly increased in all asthmatics (n=26) compared with healthy controls (n=8) (p=0.007) with highest levels observed in eosinophilic asthma (EA; median 0.22%, IQR 0.11-0.47%; n=14) compared with non-EA (0.06%, 0.00-0.20%; n=12; p<0.05). In asthmatics, basophils were positively correlated with sputum eosinophils (r=0...

Bronchiolitis is the leading cause of infant hospitalizations in the United States. Despite clinical practice guidelines discouraging the utilization of non-evidence-based therapies, there continues to be wide variation in care and resource utilization. A pre-post physician focused educational intervention was conducted with the aims to reduce the use of non-evidence-based medical therapies, including bronchodilators, among patients admitted for bronchiolitis. Among patients meeting inclusion criteria (pre: n = 45; post: n = 47), bronchodilator use decreased by 50% ( P < ...

Spirometry is a physiological test for assessing the functional aspect of the lungs using an objective indicator to measure the maximum amount of air that a patient can inhale and exhale. Acceptable spirometry testing needs to be conducted three times by an acceptable and reproducible method for determining forced vital capacity (FVC). Until the results of three tests meet the criteria of reproducibility, the test should be repeated up to eight times. Interpretation of spirometry should be clear, concise, and informative...

Severe mycoplasma pneumonia is a rare entity with only 0.5-2% of cases having a fulminant course. We present a 74-year-old woman with hypertension, diabetes mellitus and remote history of marginal zone B-cell lymphoma admitted with abdominal pain and diarrhea of 1-2 days associated with body-aches, dyspnea, dry cough and weight loss for 2-3 weeks. On physical exam, she was febrile, tachypneic, tachycardic and hypoxic on room air. Chest examination revealed diffuse crackles and end-expiratory wheezes. Laboratory tests showed anemia, acute-on-chronic kidney injury and hyaline casts and epithelial cells in the urine analysis...

Sedation is often required to perform pulmonary function testing (PFT) in horses, but drug effects may influence respiratory function. The current study was designed to characterise the effects of sedation and bronchodilator administration on absolute and relative indices of pulmonary function during eupnoeic respiration and carbon dioxide-induced hyperpnoea (rebreathing) in healthy horses using a pneumotachographic spirometry system. Sedation with acetylpromazine (ACP), xylazine, or both drugs in combination was associated with significant reductions in respiratory frequency, minute ventilation and peak airflows during eupnoeic respiration...

The diagnosis of chronic obstructive pulmonary disease (COPD) should be suspected in patients with risk factors (primarily a history of smoking) who report dyspnea at rest or with exertion, chronic cough with or without sputum production, or a history of wheezing. COPD may be suspected based on findings from the history and physical examination, but must be confirmed by spirometry to detect airflow obstruction. Findings that are most helpful to rule in COPD include a smoking history of more than 40 pack-years, a self-reported history of COPD, maximal laryngeal height, and age older than 45 years...

BACKGROUND: Long-acting bronchodilators (LABDs) are recommended as a first-line maintenance therapy in patients with moderate or severe chronic obstructive pulmonary disease (COPD). The aim of the study was to explore potential ethnic differences in persistence with LABD in COPD patients. METHODS: A cohort of COPD patients diagnosed in 2003-2007 in Copenhagen, Denmark, was followed for 2 years in the Danish national registers. According to the number of the LABD medications dispensed, individuals were categorized into three therapy groups: monotherapy, drug combination therapy, and multiple drug therapy...

Rationale Associations between fetal growth restriction and lung function impairment could be due to gestational age, shared (familial) genetic and environmental factors. Objectives To study the association between fetal growth and lung function in childhood, while taking gestational age and familial factors into account. Methods Firstly, full cohort analyses of twins were performed to study the association between birth weight, gestational age and fetal growth and lung function (forced expiratory volume in first second (FEV1), forced vital capacity (FVC) and FEV1/FVC) in z-scores before (n=520) and after (n=539) bronchodilator treatment...

Primary benign tumors of trachea are rare. Of them, tracheal leiomyoma, constitutes only 1% of all benign lower respiratory tract tumors. Here, we present a case of tracheal leiomyoma who has been receiving high doses of inhaled corticosteroids and bronchodilators for a year with a misdiagnosis of asthma. As the symptoms did not resolve with an overtreatment, she has been undergone radiologic study to find a possible alternative diagnosis.

REVIEW
Kerry-Ann F O'Grady, Keith Grimwood
Chronic suppurative lung disease (CSLD) and bronchiectasis in children and adolescents are important causes of respiratory morbidity and reduced quality of life (QoL), also leading to subsequent premature death during adulthood. Acute respiratory exacerbations in pediatric CSLD and bronchiectasis are important markers of disease control clinically, given that they impact upon QoL and increase health-care-associated costs and can adversely affect future lung functioning. Preventing exacerbations in this population is, therefore, likely to have significant individual, familial, societal, and health-sector benefits...

BACKGROUND: Bronchodilators such as long-acting muscarinic antagonists (LAMAs) and long-acting β2-agonists (LABAs) are central to the pharmacological management of COPD. Dual bronchodilation with umeclidinium/vilanterol (UMEC/VI; 62.5/25 μg) is a novel LAMA/LABA combination approved for maintenance treatment for patients with COPD. OBJECTIVE: The objective of this study was to assess the cost-effectiveness of maintenance treatment with UMEC/VI compared with tiotropium (TIO) 18 μg, open dual LAMA + LABA treatment, or no long-acting bronchodilator treatment in patients with moderate to very severe COPD...
