pulmonary hypertension (ph) is an important cause of heart failure in chronic obstructive pulmonary disease (copd). the pro brain natriuretic peptide n-terminal (nt-probnp) has been suggested as a noninvasive marker to evaluate ventricular function. however, there is no evidence to support the use of nt-probnp in monitoring the benefits of vasodilators in copd induced ph. thus, we used nt-probn...

background: several studies have showed an increased prevalence of airflow obstruction in first degree relatives of individuals with chronic obstructive pulmonary disease (copd). considering no specific research had evaluated airway resistance in offspring of patients with severe copd, we utilized a spirometry and a impulse oscillometry (io) to evaluate this population. materials and methods: i...

Little is known about causes of death in chronic obstructive pulmonary disease (COPD) and the validity of mortality statistics in COPD. The present authors examined causes of death using data from the Copenhagen City Heart Study. Of the 12,979 subjects with sufficient data from the baseline examination during 1976-1978, 6,709 died before 2001. Of these, 242 died with COPD as cause of death. Amo...

Chronic pulmonary disorders are a set of diseases that restrict respiration airflow(1).Most of these diseases are chronic obstructive pulmonary disease (COPD)(1). According to the WHO  report, mortality from COPD is increasing worldwide. It is expected to be the third leading cause of death worldwide by 2030(2) (the sixth leading cause of death in 1990(3). This disease causes significant costs ...

background and purpose: chronic obstructive pulmonary disease (copd) has been recognized as a risk factor for invasive aspergillosis. airway colonization by aspergillus species is a common feature of chronic pulmonary diseases. nowadays, the incidence of copd has increased in critically ill patients. the aim of the present study was to isolate and identify aspergillus colonies in the respirator...

conclusions we found statistical differences in pct levels that would differentiate cap from acute exacerbation of copd in the ed setting. further studies are required to verify this finding. methods this cross-sectional prospective descriptive study was performed in the emergency department (ed) on patients with cap and acute exacerbation of copd. a total of 53 patients were included in this s...

introduction: corticosteroids are routinely used in management of chronic obstructive pulmonary disease (copd) exacerbation. the main purpose of present study was to compare the efficacy of methyl prednisolone (mp) and dexamethasone (dxm) for this purpose. methods: adult copd patients entered the present clinical trial. all patients received standard treatment on admission and were then divided...

Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disease characterized by slow progression and caused the inhalation of harmful particulate matter. Cigarette smoke air pollutants are primary contributing factors. Currently, pathogenesis COPD remains incompletely understood. The PI3K/Akt signaling pathway has recently emerged as critical regulator inflammation oxidative stre...

  Background :Chronic obstructive pulmonary disease (COPD) is a third leading cause of death.   Methods : In this case control study, we prepared 5 cc bloods from the antecubital vein of 100 COPD patients and 40 healthy individuals as control group. Vascular endothelial growth factor (VEGF) expression protein level was measured by ELISA in both groups.   Results : We found that concentration of...

To provide high-quality guideline-based care for patients with asthma or chronic obstructive pulmonary disease (COPD) we must first establish the correct diagnosis. The National Asthma and COPD Audit Programme (NACAP) has highlighted an important issue across England, Scotland, Wales that potentially undermines many people airways disease.
