Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality, with exacerbations contributing strongly to the overall severity and burden of disease at the individual level. Many patients with COPD are managed predominantly in the primary care setting; therefore, primary care physicians (PCPs) must have awareness and understanding of the causes, effects, and management of exacerbations in COPD. This review offers practical information regarding how exacerbations are defined in the treatment setting, pathogenic and environmental causes, options for exacerbation treatment and prevention, and suggestions for improving care in the clinic...

Nontypeable Haemophilus influenzae (NTHi) is an exclusively human pathobiont that plays a critical role in the course and pathogenesis of chronic obstructive pulmonary disease (COPD). NTHi causes acute exacerbations of COPD and also causes persistent infection of the lower airways. NTHi expresses four IgA protease variants (A1, A2, B1, and B2) that play different roles in virulence. Expression of IgA proteases varies among NTHi strains, but little is known about the frequency and mechanisms by which NTHi modulates IgA protease expression during infection in COPD...

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)...

BACKGROUND: Among the adults and children aged 5 yrs who attend PHC settings, 20-30% seeks to care for respiratory symptoms. Over 80-90% of the respiratory patients suffer from acute respiratory infections (ARI), followed by chronic obstructive pulmonary diseases (COPD), asthma, and less frequently with pneumonia and tuberculosis (TB). To improve the quality of care in patients who seek assistance for respiratory symptoms in PHC settings and the efficiency of respiratory service delivery within healthcare systems, WHO has designated several initiatives among which one is PAL (Practical Approach to Lung Health)...

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...

There are limited data on the epidemiology of acute respiratory failure necessitating mechanical ventilation in patients with severe chronic obstructive pulmonary disease (COPD). The prognosis of acute respiratory failure requiring invasive mechanical ventilation is believed to be grim in this population. The purpose of this study was to illustrate the epidemiologic characteristics and outcomes of patients with underlying severe COPD requiring mechanical ventilation.A retrospective study of patients admitted to a quaternary referral medical intensive care unit (ICU) between January 2008 and December 2012 with a diagnosis of severe COPD and requiring invasive mechanical ventilation for acute respiratory failure...

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...

Psychological distress is common among patients with chronic obstructive pulmonary disease (COPD). This study aimed to assess whether a 10-minute mindfulness intervention reduces distress and breathlessness, improves mood and increases mindfulness among hospital inpatients following acute exacerbation of COPD.Fifty patients were recruited following an acute admission. The immediate effects of a 10-minute mindfulness-based body scan were compared with a control intervention. Participants were randomized to receive either a mindfulness-based body scan ( n = 24) or a control condition ( n = 26) via a 10-minute audio recording...
