The authors performed bronchoscopic examination using an ultrathin bronchoscope to determine the characteristics of the peripheral airways in chronic obstructive pulmonary disease (COPD). The study population comprised 13 healthy control subjects, 10 patients with chronic bronchitis without airflow limitation, and 20 patients with COPD. The COPD patients were divided clinically into 10 with chr...

overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (copd) and obstructive sleep apnea (osa), was first defined by flenley. although it can refer to concomitant occurrence of any of the pulmonary diseases and osa, overlap syndrome is commonly considered as the coexistence of osa and copd. this disease has unique adverse health consequences distinct from ...

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 v...

Photobiomodulation is the use of visible and infrared light through emitting diodes - LED without thermal cytotoxic reactions.It was carried out a literature review with this studyto understand photobiomodulation applied to Chronic Obstructive Pulmonary Disease COPD.It survey in January 2023, SciELO, Lilacs, Pubmed, Medline Google Scholar databases. With descriptors “Low-level therapy” AND “Chr...

Chronic obstructive pulmonary disease (COPD) is the most common respiratory disorder in the UK (Shee, 2001). In 1999, the number of people who died of COPD was equal to the number who died of lung cancer (Hill and Muers, 2000). Patients' knowledge of the high level of morbidity of this disease has a large impact on their social, psychological and economic status (Addington-Hall et al, 1998). Pa...

Legionella pneumophila is a thin, aerobic, Gram-negative, pathogenic bacillus and the leading cause of Legionnaires’ disease (LD) in human, especially those with high risk conditions including immune system disorders or chronic lung diseases. The mortality rate of LD has been reported to be 60% or higher in inappropriately treated cases. Investigating the prevalence of L. pneumophila and identi...

The presence of chronic bronchitis predicts a more rapid decline of forced expiratory volume in one second (FEV(1)) in patients with chronic obstructive pulmonary disease (COPD). The hallmark of COPD is airway inflammation. It was hypothesised that COPD patients with chronic bronchitis are characterised by a distinct inflammatory cell profile, as measured in bronchial biopsies and sputum. From ...

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...

The mortality rate of chronic obstructive pulmonary disease (COPD) patients with community-acquired pneumonia (CAP) is reported to be low. However, studies carried out to date have included <20% of critically ill patients. The current authors performed a secondary analysis of a prospective study evaluating 428 immunocompetent patients admitted to the intensive care unit (ICU) for severe CAP. In...

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. To investigate effect silymarin on chronic (COPD). The serum samples 20 healthy controls, patients with acute exacerbation COPD and stable were collected. LPS smoking used to induce mouse model. Our results showed that in COPD, O2-level release from peripheral blood neutrophils negatively correlated forc...
