BACKGROUND: The aetiology of acute exacerbations of COPD (AECOPD) is incompletely understood. Understanding the relationship between chronic bacterial airway infection and viral exposure may explain the incidence and seasonality of these events. METHODS: In this prospective, observational cohort study (NCT01360398), patients with COPD aged 40-85 years underwent sputum sampling monthly and at exacerbation for detection of bacteria and viruses. Results are presented for subjects in the full cohort, followed for 1 year...

BACKGROUND: Epigenetics changes have been shown to be affected by cigarette smoking. Cigarette smoke (CS)-mediated DNA methylation can potentially affect several cellular and pathophysiological processes, acute exacerbations, and comorbidity in the lungs of patients with chronic obstructive pulmonary disease (COPD). We sought to determine whether genome-wide lung DNA methylation profiles of smokers and patients with COPD were significantly different from non-smokers. We isolated DNA from parenchymal lung tissues of patients including eight lifelong non-smokers, eight current smokers, and eight patients with COPD and analyzed the samples using Illumina's Infinium HumanMethylation450 BeadChip...

With an increasing ageing population who often have multiple long-term conditions, there is a growing need to provide an alternative type of care to the traditional hospital-based model. 'Hospital in the Home' is a model that provides integrated care for patients in their home. The @home service was established in 2013 by Guy's and St Thomas' NHS Foundation Trust. The service provides health care in patients' home, supporting early discharge from hospital as well as preventing avoidable admissions and readmissions saving valuable hospital bed days and reducing length of stay...

Dural prostate metastases (DPM) are a rare manifestation of metastatic prostate cancer seen in approximately one to six percent of cases. Presenting symptoms may include signs of elevated intracranial pressure, headache, altered mental status, or cranial nerve palsies. Hearing loss, sensory changes, dysarthria, and dysphagia are rare symptoms in DPM that were present in our patient. We present a case of a 58-year-old male with a known diagnosis of adenocarcinoma of the prostate presenting with symptoms of acute exacerbation of chronic obstructive pulmonary disease (COPD), sub-acute right-sided hearing loss, and right-sided facial paralysis...

Extracorporeal CO2 removal (ECCO2R) is becoming an increasingly established treatment option for patients with acute severe hypercapnic respiratory failure. Technically, pumpless arterio-venous systems using the natural arterio-venous pressure gradient and also pump-driven veno-venous systems are available. Here, veno-venous ECCO2R has become the preferred technique, as settings for arterio-venous ECCO2R are restricted and side effects are more common with arterio-venous ECCO2R. Using veno-venous ECCO2R with blood flow rates up to 450 ml/min 60 to 80 ml CO2 can be removed per minute corresponding to 20 to 30 % of the total amount of CO2 production...

Airway mucus hypersecretion is a frequent symptom associated with acute and chronic airway disease. Inhibition of mucus production or promotion of mucolysis not only relieved symptoms but also improved disease outcomes. There are numerous available mucoactive medicines for prescription, and how to select them properly for different diseases is important for clinical practice. So far, there is no one consensus or guideline reported. A group of Chinese pulmonary physicians worked together to complete this consensus based on literature review, summarized mechanism and usage of each classical mucoactive medicine...

Chronic obstructive pulmonary disease (COPD) is a multisystem disorder. Abnormal body composition (BC) and low serum micronutrient levels contribute significantly to morbidity associated with acute exacerbations of COPD (AECOPD). The BC and serum levels of selected micronutrients were recorded in prospective, consecutive patients admitted to hospital with an AECOPD in Western Sydney. 94 patients were enrolled, 43% female, the average age was 69.8 ± 8.2years(SD). Admission spirometry revealed a mean spirometric ratio of 0...

Exacerbations of COPD are clinically relevant events with therapeutic and prognostic implications. Yet, significant heterogeneity of clinical presentation and disease progression exists within acute exacerbations of COPD (AECOPD). Currently, different phenotypes have been widely used to describe the characteristics among patients with AECOPD. This has proved to be significant in the treatment and prediction of the outcomes of the disease. In this review of published literature, the phenotypes of AECOPD were classified according to etiology, inflammatory biomarkers, clinical manifestation, comorbidity, the frequency of exacerbations, and so on...

Chronic obstructive pulmonary disease (COPD) is a leading cause of hospital admission, the fifth leading cause of death in North America, and is estimated to cost $49 billion annually in North America by 2020. The majority of COPD care costs are attributed to hospitalizations; yet, there are limited data to understand the drivers of high costs among hospitalized patients with COPD. In this study, we aimed to determine the patient and hospital-level factors associated with high-cost hospital care, in order to identify potential targets for the reorganization and planning of health services...

During acute exacerbation of chronic obstructive pulmonary disease (AECOPD), myocardial stress may be aggravated. Sparse data exist concerning the prevalence and correlates of cardiac arrhythmias in the stable and exacerbated states of COPD. We hypothesized that AECOPD is associated with increased prevalence of cardiac arrhythmias independent of COPD-severity and co-morbidity, and explored possible mechanisms. A 24-hour Holter recording was obtained in 74 patients with stable COPD and 45 patients with AECOPD (mean age 54 years, 56% women)...

OBJECTIVES: A number of observational studies have reported that, in patients with chronic obstructive pulmonary disease (COPD), β blockers (BBs) decrease risk of mortality and COPD exacerbations. To address important methodological concerns of these studies, we compared the effectiveness and safety of cardioselective BBs versus non-dihydropyridine calcium channel blockers (non-DHP CCBs) in patients with COPD and acute coronary syndromes (ACS) using a propensity score (PS)-matched, active comparator, new user design...

Acute exacerbation of chronic obstructive pulmonary disease (COPD) is often induced by infection and often has a poor prognosis. Bacterial LPS activates innate immune receptor TLR4 followed by activation of a transcriptional factor IFN regulatory factor-3 (IRF3) as well as NF-κB, resulting in upregulation of various inflammatory mediators. To clarify the role of IRF3 in the pathogenesis of LPS-triggered COPD exacerbation, porcine pancreatic elastase (PPE) followed by LPS was administered intranasally to wild-type (WT) or IRF3(-/-) male mice...

PURPOSE: Cough is common in chronic obstructive pulmonary disease (COPD) and is associated with frequent exacerbations and increased mortality. Cough increases during acute exacerbations (AE-COPD), representing a possible metric of clinical deterioration. Conventional cough monitors accurately report cough counts over short time periods. We describe a novel monitoring system which we used to record cough continuously for up to 45 days during AE-COPD convalescence. METHODS: This is a longitudinal, observational study of cough monitoring in AE-COPD patients discharged from a single teaching hospital...

BACKGROUND: COPD is a leading cause of mortality worldwide, and cigarette smoke is a pivotal risk factor. Adenovirus is a common cause of acute exacerbations of COPD and expedites COPD progression. Lung stem/progenitor cells play an important role in the development of COPD, while the relevant mechanism remains elusive. Here, we investigated the number of lung CD31(-)CD45(-)Sca-1(+) cells and sonic hedgehog (Shh) signaling pathway expression levels in cigarette smoke extract (CSE)-induced emphysema mice, as well as the relevant effects of acute adenovirus infection (AAI)...

Chronic obstructive pulmonary disease (COPD) and cardiovascular diseases often coexist. The mechanistic links between these two diseases are complex, multifactorial and not entirely understood, but they can influence the therapeutic approach. Therapy can be primarily directed towards treating the respiratory symptoms and reducing lung inflammation. Smoking cessation, bronchodilators and inhaled corticosteroids are central to this therapeutic approach. The underlying pathophysiological mechanisms that are responsible for the increased cardiovascular risk in COPD remain unclear, but might include arterial stiffness, inflammation and endothelial dysfunction as a consequence of systemic exposure to chemicals in cigarette smoke or airborne pollution...
