BACKGROUND: The diagnosis of COPD in patients hospitalized for AECOPD can be confirmed by spirometry showing obstruction or radiographs showing emphysema. The evidence for COPD is sometimes absent or contradicts this diagnosis. The inaccurate attribution of the exacerbation to COPD can lead to suboptimal care and worse outcome. OBJECTIVES: We determined if the presence of tests that confirm the diagnosis of COPD has any implications on the course of the hospitalization and readmission rate...

BACKGROUNDS: CD4 + Th1-CXCR3 signaling pathway may play a key role in Chronic Obstructive Pulmonary Disease (COPD). The aim of this study was to explore Th1/Th2 cytokines ratio differences of patients in different stages of COPD and to confirm the hypothesis that elastin exposure might serve as an antigen to initiate the stimulation of CD4 + Th1-CXCR3 immune inflammation pathway. METHODS: Patients of COPD in different stages and normal individuals were enrolled...

INTRODUCTION: Despite rising antimicrobial resistance, treatment guidelines for COPD exacerbations are frequently ignored. Patients with terminal conditions are often prescribed antimicrobials despite the goal of care to reduce burdensome treatments. The appropriateness of antimicrobials in patients dying from an exacerbation of COPD is unknown. AIM: To review antimicrobial prescription at the time of death in patients who died from COPD. METHODS: A retrospective medical record audit was performed for 475 patients who died over twelve years (2004-2015)...

Chronic obstructive pulmonary disease (COPD) is associated with irreversible persistent airflow limitation and enhanced inflammation. The episodes of acute exacerbation (AECOPD) largely depend on the colonized pathogens such as nontypeable Haemophilus influenzae (NTHi), one of the most commonly isolated bacteria. Regulatory T cells (Tregs) are critical in controlling inflammatory immune responses and maintaining tolerance; however, their role in AECOPD is poorly understood. In this study, we hypothesized a regulatory role of Tregs, as NTHi participated in the progress of COPD...

BACKGROUND: Timely diagnosis of acute exacerbations of COPD (AECOPD) is challenging as it depends on patients' reports. AECOPD are characterised by increased airway obstruction, mucus and air trapping, which results in changes in lung acoustics. Thus, adventitious respiratory sounds (ARS) may be useful to detect/monitor AECOPD. OBJECTIVE: To evaluate computerised ARS changes during AECOPD. METHODS: 25 non-hospitalised patients with AECOPD (16♂, 70 [62...

Background: Static hyperinflation is known to be increased during moderate acute exacerbations of chronic obstructive pulmonary disease (COPD) (AECOPD), but few data exist in patients with severe exacerbations of COPD. The role of dynamic hyperinflation during exacerbations is unclear. Methods: In a prospective, observational cohort study, we recruited patients admitted to hospital for AECOPD. The following measurements were performed upon admission and again after resolution (stable state) at least 42 days later: inspiratory capacity (IC), body plethysmography, dynamic hyperinflation by metronome-paced IC measurement, health-related quality of life and dyspnea...

INTRODUCTION AND OBJECTIVE: Muscle dysfunction is very common in patients with chronic obstructive pulmonary disease (COPD). Muscular strength depletion is a result of numerous hospitalisations and this causes an increase in the symptomatology. Numerous interventions have been used in these patients, but there is no consensus on the best. The main objective of this study is to compare the effectiveness of two physiotherapy interventions during hospitalisation in COPD patients. PATIENTS AND METHODS: In this clinical trial, we included 39 patients who were randomised into three groups...

BACKGROUND: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are common in patients with underlying moderate to severe COPD and are associated with increased health and economic burden. International and Chinese guidelines recommend using glucocorticoids for the management of AECOPD because glucocorticoid therapy has been shown to benefit clinical outcomes. However, only scant data are available for current status of glucocorticoid therapy in hospitalized AECOPD patients in China...

The NLR pyrin domain-containing protein 3 (NLRP3) inflammasome, a multi-protein complex, produces the pro-inflammatory cytokines interleukin (IL)-1β and IL-18, which may contribute to the development of airway inflammation in chronic obstructive pulmonary disease (COPD). The aim of this study was to explore the correlation between circulating and local airway NLRP3 inflammasome activation with acute exacerbation of COPD (AECOPD). mRNA levels of NLRP3, Caspase (Casp)-1, apoptosis-associated speck-like protein containing CARD (ASC), IL-18, and IL-1β in peripheral blood mononuclear cells (PBMCs) and bronchial tissues were determined by real-time PCR in 32 smokers, 65 patients with AECOPD, 50 COPD patients in recovery stage, and 30 COPD patients in stable stage...
