Abstract
INTRODUCTION Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) increases the risk of pulmonary embolism (PE). AECOPD and PE have similar symptoms which results in a high proportion of patients with AECOPD undergoing imaging to rule out PE. Finding predictors and explanatory factors of PE in AECOPD, such as purulence status, could help reduce the need for imaging. This systematic review with meta-analysis aims to evaluate if there is an association between purulence status in AECOPD and PE diagnosis. METHODS AND ANALYSIS MEDLINE, EMBASE and CENTRAL will be searched from database inception to April 2024. Randomised trials, cohort studies and cross-sectional studies on the prevalence of PE in patients with AECOPD will be included if the prevalence of PE based on the AECOPD purulence status is available. There will be no restriction on language. The primary outcome will be PE at the initial assessment and secondary outcomes will be all venous thromboembolism (deep venous thrombosis (DVT) and PE) and DVT, respectively, diagnosed at the initial assessment. Relative risks with their 95% CI will be calculated by using a Mantel-Haenszel random-effect model to compare the association between the risk of PE and the AECOPD purulence status (purulent vs non-purulent/unknown). Subgroup analyses will be performed based on the type of study, systematic search of PE versus no systematic search of PE and localisation of PE. Risk of bias will be evaluated by the ROBINS-E tool, publication bias will be evaluated with the funnel plot. The manuscript will be drafted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. ETHICS AND DISSEMINATION This study does not require ethics approval. This work will be submitted for presentation at an international conference and for publication in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42023459429.

Deng R, Ma X, Zhang H, Chen J, Liu M, Chen L, Xu H. Role of HIF-1α in hypercoagulable state of COPD in rats. Arch Biochem Biophys 2024; 753:109903. [PMID: 38253248 DOI: 10.1016/j.abb.2024.109903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 01/18/2024] [Accepted: 01/19/2024] [Indexed: 01/24/2024]
Abstract
OBJECTIVE To explore the role of HIF-1α in hypercoagulable state of COPD induced by lipopolysaccharide plus smoking in rats. It also has to explore the regulatory mechanism of HIF-1α-EPO/EDN-1/VEGF pathway by using its activator and inhibitor. METHODS 60 Sprague-Dawley rats (SD rats) were randomly divided into healthy control group, COPD hypercoagulable control group, activator group, and inhibitor group with 15 rats in each group. The healthy control group was fed freely. The other groups were given smoke and lipopolysaccharide by tracheal instillation to establish the experimental animal model of COPD hypercoagulability. After successful modeling, each experimental group was given 0.9 % sodium chloride solution and corresponding drugs by intraperitoneal injection for 7 days. Lung function was detected after drug administration. Hematoxylin-eosin staining was used to observe the pathological changes of lung tissue. Enzyme-linked immunosorbent assay was used to detect serum D-D,F (1 + 2),IL-6,TNF-α. The mRNA expressions of HIF-1α, EPO, EDN-1, and VEGF were detected by RT-PCR. Western-Blot and IHC were used to detect the expression of HIF-1α, EPO, EDN-1, and VEGF in lung tissue of rats. RESULTS Compared with the healthy control group, rats in COPD hypercoagulable control group had COPD symptoms/signs, decreased lung function, increased the expression of serum D-D and F (1 + 2), increased the expression of inflammatory factors IL-6,TNF-α, and increased the expression of proteins HIF-1α, EPO, EDN-1 and VEGF. Compared with COPD hypercoagulable control group, lung function in activator group and inhibitor group had no obvious changes. The expressions of serum D-D,F (1 + 2),IL-6,TNF-α in activator group have increased noticeably. The expressions of proteins HIF-1α, EPO, EDN-1, and VEGF have further increased. Compared with COPD hypercoagulable control group, the expression of serum D-D, F (1 + 2), HIF-1α, EPO, EDN-1, and VEGF in the inhibitor group decreased. CONCLUSION HIF-1α-EPO/EDN-1/VEGF pathway plays an important role in the hypercoagulable state of COPD. HIF-1α inhibitor can improve airway inflammation and reduce hypercoagulability in COPD model rats.

Pulmonary embolism diagnostic strategies in patients with COPD exacerbation: Post-hoc analysis of the PEP trial. Thromb Res 2023; 231:58-64. [PMID: 37806116 DOI: 10.1016/j.thromres.2023.09.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 08/27/2023] [Accepted: 09/25/2023] [Indexed: 10/10/2023]
Abstract
BACKGROUND The prevalence of pulmonary embolism (PE) is approximately 11-17 % in patients with an acute exacerbation of chronic obstructive pulmonary disease (AE-COPD). The optimal diagnostic strategy for PE in these patients remains undetermined. AIMS To evaluate the safety and efficacy of standard (revised Geneva and Wells PE scores combined with fixed D-dimer cut-off) and computed tomography pulmonary angiogram (CTPA)-sparing diagnostic strategies (ADJUST-PE, YEARS, PEGeD, 4PEPS) in patients with AE-COPD. METHOD Post-hoc analyses of data from the multicenter prospective PEP study were performed. The primary outcome was the diagnostic failure rate of venous thromboembolism (VTE) during the entire study period. Secondary outcomes included diagnostic failure rate of PE and deep venous thrombosis (DVT), respectively, during the entire study period and the number of CTPA needed per diagnostic strategy. RESULTS 740 patients were included. The revised Geneva and Wells PE scores combined with fixed D-dimer cut-off had a diagnostic failure rate of VTE of 0.7 % (95%CI 0.3 %-1.7 %), but >70.0 % of the patients needed imaging. All CTPA-sparing diagnostic algorithms reduced the need for CTPAs (-10.1 % to -32.4 %, depending on the algorithm), at the cost of an increased VTE diagnosis failure rate of up to 2.1 % (95%CI 1.2 %-3.4 %). CONCLUSION Revised Geneva and Wells PE scores combined with fixed D-dimer cut-off were safe, but a high number of CTPA remained needed. CTPA-sparing algorithms would reduce imaging, at the cost of an increased VTE diagnosis failure rate that exceeds the safety threshold. Further studies are needed to improve diagnostic management in this population.

Prevalence, Risk Factor and Clinical Characteristics of Venous Thrombus Embolism in Patients with Acute Exacerbation of COPD: A Prospective Multicenter Study. Int J Chron Obstruct Pulmon Dis 2023; 18:907-917. [PMID: 37223656 PMCID: PMC10202142 DOI: 10.2147/copd.s410954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Accepted: 04/29/2023] [Indexed: 05/25/2023] Open
Abstract
Background and Objective The prevalence of venous thrombus embolism (VTE) in patients with chronic obstructive pulmonary disease (COPD) is higher than in patients without COPD. Owing to the similarity of clinical symptoms between PE and acute exacerbation COPD (AECOPD), PE is likely to be overlooked or underdiagnosed in patients with AECOPD. The aim of the study was to investigate the prevalence, risk factor, clinical characteristics, and prognostic impact of VTE in patients with AECOPD. Methods This multicenter, prospective, cohort study was conducted in 11 research centers of China. Data on the baseline characteristics, VTE-related risk factors, clinical symptoms, laboratory examination results, computed tomography pulmonary angiography (CTPA) and lower limb venous ultrasound of AECOPD patients were collected. Patients were followed up for 1 year. Results A total of 1580 AECOPD patients were included in the study. The mean (SD) age was 70.4 (9.9) years and 195 (26%) patients were women. The prevalence of VTE was 24.5% (387/1580) and PE was 16.8% (266/1580). VTE patients were older; had higher BMI; and longer course of COPD than non-VTE patients. The history of VTE, cor pulmonale, less purulent sputum, increased respiratory rate, higher D-dimer, and higher NT-proBNP/BNP were independently associated with VTE in hospitalized patients with AECOPD. The mortality at 1-year was higher in patients with VTE than patients without VTE (12.9% vs 4.5%, p<0.01). There was no significant difference in the prognosis of patients with PE in segmental or subsegmental arteries and in main pulmonary arteries or lobar arteries (P>0.05). Conclusion VTE is common in COPD patients and is associated with poor prognosis. Patients with PE at different locations had poorer prognosis than patients without PE. It is necessary to perform active screening strategy for VTE in AECOPD patients with risk factors.
