Project description:Investigation of whole genome gene expression level changes of the dynamic gene profiling of peripheral blood mononuclear cells (PBMCs) from patients with AECOPD) on day1, 3 and 10, compared to the normal people and stable COPD patients. A five chip study using total RNA recovered from Peripheral Blood Mononuclear Cell of Peripheral Blood.Evaluating the dynamic gene profiling of peripheral blood mononuclear cells (PBMCs) from patients with AECOPD) on day1, 3 and 10 after the hospital admission, to compared with healthy controls or patients with stable COPD. Slides were scanned at 5 μm/pixel resolution using an Axon GenePix 4000B scanner (Molecular Devices Corporation) piloted by GenePix Pro 6.0 software (Axon). Scanned images (TIFF format) were then imported into NimbleScan software (version 2.5) for grid alignment and expression data analysis. Expression data were normalized through quantile normalization and the Robust Multichip Average (RMA) algorithm included in the NimbleScan software. The Probe level (*_norm_RMA.pair) files and Gene level (*_RMA.calls) files were generated after normalization.

Project description:BackgroundHospitalization of patients with chronic obstructive pulmonary disease creates a huge healthcare burden. Positive airway pressure therapy is sometimes used in patients with chronic obstructive pulmonary disease, but the possible impact on hospitalization risk remains controversial. We studied the hospitalization risk of patients with chronic obstructive pulmonary disease before and after initiation of various positive airway pressure therapies in a "real-world" bioinformatics study.MethodsWe performed a retrospective analysis of administrative claims data of hospitalizations in patients with chronic obstructive pulmonary disease who received or did not receive positive airway pressure therapy: continuous positive airway pressure, bilevel positive airway pressure, and noninvasive positive pressure ventilation using a home ventilator.ResultsThe majority of 1,881,652 patients with chronic obstructive pulmonary disease (92.5%) were not receiving any form of positive airway pressure therapy. Prescription of bilevel positive airway pressure (1.5%), continuous positive airway pressure (5.6%), and noninvasive positive pressure ventilation (<1%) in patients with chronic obstructive pulmonary disease demonstrated geographic-, sex-, and age-related variability. After adjusting for confounders and propensity score, noninvasive positive pressure ventilation (odds ratio [OR], 0.19; 95% confidence interval [CI], 0.13-0.27), bilevel positive airway pressure (OR, 0.42; 95% CI, 0.39-0.45), and continuous positive airway pressure (OR, 0.70; 95% CI, 0.67-0.72) were individually associated with lower hospitalization risk in the 6 months post-treatment when compared with the 6 months pretreatment but not when compared with the baseline period between 12 and 6 months before treatment initiation. Stratified analysis suggests that comorbid sleep-disordered breathing, chronic respiratory failure, heart failure, and age less than 65 years were associated with greater benefits from positive airway pressure therapy.ConclusionInitiation of positive airway pressure therapy was associated with reduction in hospitalization among patients with chronic obstructive pulmonary disease, but the causality needs to be determined by randomized controlled trials.

Project description:Chronic obstructive pulmonary disease (COPD) is characterised by progressive airflow obstruction that is only partly reversible, inflammation in the airways, and systemic effects or comorbities. The main cause is smoking tobacco, but other factors have been identified. Several pathobiological processes interact on a complex background of genetic determinants, lung growth, and environmental stimuli. The disease is further aggravated by exacerbations, particularly in patients with severe disease, up to 78% of which are due to bacterial infections, viral infections, or both. Comorbidities include ischaemic heart disease, diabetes, and lung cancer. Bronchodilators constitute the mainstay of treatment: β(2) agonists and long-acting anticholinergic agents are frequently used (the former often with inhaled corticosteroids). Besides improving symptoms, these treatments are also thought to lead to some degree of disease modification. Future research should be directed towards the development of agents that notably affect the course of disease.

Project description:ObjectivesTo integrate evidence from randomised controlled trials (RCTs) and observational studies on the efficacy of inhaled treatments for chronic obstructive pulmonary disease using network meta-analyses.MethodsSystematic searches MEDLINE and Embase based on predetermined criteria. Network meta-analyses of RCTs investigated efficacy on exacerbations (long-term: ≥20 weeks of treatment; short-term: <20 weeks), lung function (≥12 weeks), health-related quality of life, mortality and adverse events. Qualitative comparisons of efficacies between RCTs and observational studies.Results212 RCTs and 19 observational studies were included. Compared with combined long-acting beta-adrenoceptor agonists and long-acting muscarinic antagonists (LABA+LAMA), triple therapy (LABA+LAMA+inhaled corticosteroid) was significantly more effective at reducing exacerbations (long-term 0.85 (95% CI: 0.78 to 0.94; short-term 0.67 (95% CI: 0.49 to 0.92)) and mortality (0.72 (95% CI: 0.59 to 0.89)) but was also associated with increased pneumonia (1.35 (95% CI: 1.10 to 1.67)). No differences in lung function (0.02 (95% CI: -0.10 to 0.14)), health-related quality of life (-1.12 (95% CI: -3.83 to 1.59)) or other adverse events (1.02 (95% CI: 0.96 to 1.08)) were found. Most of the observational evidence trended in the same direction as pooled RCT data.ConclusionFurther evidence, especially pragmatic trials, are needed to fully understand the characteristics of patient subgroups who may benefit from triple therapy and for those whom the extra risk of adverse events, such as pneumonia, may outweigh any benefits.Prospero registration numberCRD42018088013.
