Abstract
Background Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. There is no nomogram model available for mortality prediction of stable COPD. We intended to develop and validate a nomogram model to predict mortality risk in stable COPD patients for personalised prognostic assessment. Methods A prospective observational study was made of COPD outpatients registered in the RealDTC study between December 2016 and December 2019. Patients were randomly assigned to the training cohort and validation cohort in a ratio of 7:3. We used Lasso regression to screen predicted variables. Further, we evaluated the prognostic performance using the area under the time-dependent receiver operating characteristic curve (AUC) and calibration curve. We used the AUC, concordance index, and decision curve analysis to evaluate the net benefits and utility of the nomogram compared with three earlier prediction models. Results Of 2499 patients, the median follow-up was 38 months. The characteristics of the patients between the training cohort (n = 1743) and the validation cohort (n = 756) were similar. ABEODS nomogram model, combining age, body mass index, educational level, airflow obstruction, dyspnoea, and severe exacerbation in the first year, was constructed to predict mortality in stable COPD patients. In the integrative analysis of training and validation cohorts of the nomogram model, the three-year mortality prediction achieved AUC = 0.84; 95% confidence interval (CI) = 0.81, 0.88 and AUC = 0.80; 95% CI = 0.74, 0.86, respectively. The ABEODS nomogram model preserved excellent calibration in both the training cohort and validation cohort. The time-dependent AUC, concordance index, and net benefit of the nomogram model were higher than those of BODEx, updated ADO, and DOSE, respectively. Conclusions We developed and validated a prognostic nomogram model that accurately predicts mortality across the COPD severity spectrum. The proposed ABEODS nomogram model performed better than earlier models, including BODEx, updated ADO, and DOSE in Chinese patients with COPD. Registration ChiCTR-POC-17010431.

The clinical characteristics and outcomes of different inhaled therapies in chronic obstructive pulmonary disease patients with frequent cough. Ann Med 2024; 55:2304107. [PMID: 38233371 PMCID: PMC10795788 DOI: 10.1080/07853890.2024.2304107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 12/18/2023] [Indexed: 01/19/2024] Open
Abstract
BACKGROUND Cough is a common symptom in patients with chronic obstructive pulmonary disease (COPD). Patients with cough may exhibit various clinical characteristics and experience varying outcomes based on inhaled therapies they receive. OBJECTIVES This study aimed to explore the clinical characteristics and outcomes of various inhaled therapies in COPD patients with frequent cough. METHODS This was a multicenter, prospective cohort study. Of these patients, the median cough score in COPD assessment test (CAT) was two. Patients were classified into frequent cough group if they scored two or over in the first item of CAT and infrequent cough group otherwise. Patients with frequent cough were then divided into long-acting antimuscarinic (LAMA), long-acting beta2-agonist (LABA)/LAMA, inhaled corticosteroids (ICS)/LABA and ICS/LABA/LAMA groups. Minimum clinically important difference (MCID) (CAT scores decreased ≥2 from baseline) and the improvement of cough (cough score decreased ≥1 from baseline) were collected in the six-month follow-up. Frequent exacerbations (experiencing at least two exacerbations) were collected in the one-year follow-up. RESULTS Of 906 patients, 581 (64.1%) patients reported frequent cough at the initial visit. Frequent cough was associated with the current smokers and CAT scores (p < 0.05). The MCID showed no significant difference between frequent cough and infrequent cough groups in the follow-up. More patients with frequent cough experienced future frequent exacerbations compared to those with infrequent cough. After receiving inhaled therapies, 62% of patients with frequent cough got the cough improved. More patients with frequent cough treated with LABA/LAMA or ICS/LABA/LAMA attained MCID and fewer experienced exacerbations than those treated with LAMA or ICS/LABA (p < 0.05). The change in cough score showed no difference among various inhaled therapies in patients with frequent cough. CONCLUSION COPD patients with frequent cough were related to current smokers and higher CAT scores. These patients had a higher incidence of frequent exacerbations than those with infrequent cough. Patients with frequent cough who were treated with LABA/LAMA or ICS/LABA/LAMA were more likely to attain MCID and at a lower risk of exacerbation than those treated with LAMA or ICS/LABA.

Association between occupational exposure and chronic obstructive pulmonary disease and respiratory symptoms in the Spanish population. Arch Bronconeumol 2024; 60:16-22. [PMID: 38176851 DOI: 10.1016/j.arbres.2023.10.014] [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: 06/28/2023] [Revised: 10/20/2023] [Accepted: 10/23/2023] [Indexed: 01/06/2024]
Abstract
INTRODUCTION The aim of this study was to analyze the impact of occupational exposure on chronic obstructive pulmonary disease (COPD) and respiratory symptoms in the general Spanish population. METHODS This was a study nested in the Spanish EPISCAN II cross-sectional epidemiological study that included participants who had completed a structured questionnaire on their occupational history, a questionnaire on respiratory symptoms, and forced spirometry. The data were analyzed using Chi-square and Student's t tests and adjusted models of multiple linear regression and logistic regression. RESULTS We studied 7502 subjects, 51.1% women, with a mean age of 60±11 years. Overall, 53.2% reported some respiratory symptoms, 7.9% had respiratory symptoms during their work activity, 54.2% were or had been smokers, and 11.3% (851 subjects) met COPD criteria on spirometry. A total of 3056 subjects (40.7%) reported exposure to vapors, gases, dust or fumes (VGDF); occupational exposure to VGDF was independently associated with the presence of COPD (OR 1.22, 95% CI: 1.03-1.44), respiratory symptoms (OR 1.45, 95%: CI 1.30-1.61), and respiratory symptoms at work (OR 4.69, 95% CI: 3.82-5.77), with a population attributable fraction for COPD of 8.2%. CONCLUSIONS Occupational exposure is associated with a higher risk of COPD and respiratory symptoms in the Spanish population. These results highlight the need to follow strict prevention measures to protect the respiratory health of workers.

Abstract
Chronic obstructive pulmonary disease (COPD) is a respiratory condition characterized by its heterogeneous nature, progressive course, and significant impact on individuals' quality of life. It is a prevalent global health issue affecting a substantial number of individuals and can pose life-threatening complications if left unmanaged. The development and course of COPD can be influenced by a range of risk factors, including genetic predisposition and environmental exposures. Nevertheless, as researchers adopt a more comprehensive and expansive viewpoint of therapeutic techniques, the associated obstacles become more apparent. Indeed, a definitive medication for COPD that reliably leads to symptom alleviation has not yet been discovered. Therefore, the limitations of conventional therapy methods prompted researchers to focus on the advancement of novel procedures, potentially leading to significant outcomes. In contemporary times, the field of regenerative medicine and cell therapy has presented unprecedented opportunities for the exploration of innovative treatments for COPD, owing to the distinctive attributes exhibited by stem cells. Hence, it is imperative to provide due consideration to preclinical investigations and notable characteristics of stem cells as they serve as a means to comprehensively comprehend the fundamental mechanisms of COPD and uncover novel therapeutic strategies with enhanced efficacy for patients.

Abstract
Background Education levels play a critical role in the development of chronic obstructive pulmonary disease (COPD), which mainly affects the elderly, who generally have a low level of education in China. We aimed to investigate the association between education level and COPD clinical characteristics and outcomes, especially the effects of education level on the all-cause mortality of COPD in the Chinese population. Methods We retrieved data collected between December 2016 and June 2020 in the RealDTC, an ongoing multicenter, real-world study on the status of diagnosis and treatment of COPD. The patients were classified into low- and high-education groups. We extracted data on demographics, pulmonary function, Global Initiative for Chronic Obstructive Lung Disease (GOLD) grades, modified Medical Research Council (mMRC) scores, COPD Assessment Test (CAT) scores, exacerbation history, therapy, and comorbidities, and on mortality during three years of follow-up. Results We included 4098 patients with COPD, of whom 3258 (79.5%) were of low education. This group had higher ages, CAT scores, mMRC scores, and numbers of exacerbations, as well as a greater proportion of females, never smokers, biofuel exposure, and GOLD grade 3. Logistic regression showed that being aged ≥65 years, being female, having biofuel exposure, having CAT scores of 20-29, and having ≥2 exacerbations were independently associated with having low education (P < 0.05). Furthermore, low-education COPD patients had a higher cumulative mortality risk during three years of follow-up than their high-education counterparts (hazard ratio (HR) = 1.75; 95% confidence interval (CI) = 1.17-2.61, P = 0.006). Conclusions Low-education COPD patients, who accounted for most of our sample, had a higher symptom burden, risk of exacerbation, and risk of all-cause mortality. Clinicians attending COPD patients should be more attentive of individuals with low education levels.

Abstract
BACKGROUND Smoking, biomass, and occupational exposure are the main environmental risk factors for asthma. The purpose of this study was to analyze the clinical characteristics of exposure to these risk factors in patients with asthma. METHODS This cross-sectional study enrolled patients with asthma from an outpatient department according to the Global Initiative for Asthma. Demographics, forced expiratory volume in 1 s (FEV1), FEV1%pred, FEV1/forced vital capacity (FVC), laboratory tests, asthma control test (ACT), asthma control questionnaire (ACQ) scores, and the inhaled corticosteroid (ICS) dose were recorded. A generalized linear mixed model was used to adjust for potential confounders. RESULTS A total of 492 patients with asthma were included in this study. Of these patients, 13.0% were current smokers, 9.6% were former smokers, and 77.4% were never smokers. Compared with never smokers, the current and former smokers had a longer duration of asthma; lower ACT scores, FEV1, FEV1%pred, and FEV1/FVC; and higher ACQ scores, IgE, FeNO, blood eosinophils, and ICS dose (p < .05). In addition, the patients exposed to biomass alone were older; had higher exacerbation in the past year; a longer duration of asthma; and lower FEV1, FEV1%pred, FEV1/FVC, IgE, and FeNO compared with smoking or occupational exposure alone. Compared with smoking exposure alone, patients with occupational exposure alone had a longer duration of asthma and lower FEV1, FEV1%pred, FVC, IgE, FeNO, and ICS dose (p < .05). CONCLUSIONS There are significant differences in the clinical characteristics of patients with asthma depending on the smoking status. In addition, significant differences also observed among smoking, biomass, and occupational exposure.

Abstract
OBJECTIVES The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 classified chronic obstructive pulmonary disease (COPD) patients into more and less symptomatic groups. This study aimed to analyze the clinical characteristics, risk of future exacerbation and mortality among patients in more symptomatic group. DESIGN A retrospective cohort study. SETTING Data were obtained from patients enrolled in a database setup by Second Xiangya Hospital of Central South University. PARTICIPANTS 1729 stable COPD patients listed from September 2017 to December 2019 in the database. The patients were classified into more and less symptomatic groups based on GOLD 2017 report. OUTCOMES All patients were followed up for 18 months. We collected baseline data and recorded the number of exacerbations and mortality during follow-up. RESULTS The more symptomatic patients were older, had higher Clinical COPD Questionnaire (CCQ) scores, more severe airflow limitation and higher number of exacerbations and hospitalizations in the past year (P < 0.05). Logistic regression showed that having more symptoms correlated with the CCQ scores and exacerbations in the past year (P < 0.05). After patients were followed up, there were higher numbers of exacerbations, hospitalizations and mortality rates in more symptomatic patients (P < 0.05). The multivariate model showed that age more than 65 years (OR = 2.047, 95% CI = 1.020-4.107) and COPD assessment test scores more than 30 (OR = 2.609, 95% CI = 1.339-5.085) were independent risk factors for mortality, whereas current smoker (OR = 1.565, 95% CI = 1.052-2.328), modified Medical Research Council scores (OR = 1.274, 95% CI = 1.073-1.512) and exacerbations in the past year (OR = 1.061, 95% CI = 1.013-1.112) were independent risk factors for exacerbation in more symptomatic patients (P < 0.05). CONCLUSIONS More symptomatic COPD patients have worse outcomes. In addition, several independent risk factors for exacerbation and mortality were identified. Therefore, clinicians should be aware of these risk factors and take them into account during interventions.

[PMID: 36850977 PMCID: PMC9967702 DOI: 10.3390/toxics11020102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 01/18/2023] [Accepted: 01/19/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND Sex differences in symptoms exist in patients with COPD. Our aim is to measure the differences between men and women with COPD, focusing on risk factors, symptoms, quality of life and drug prescriptions. METHODS In this cross-sectional observational study, patients with COPD were collected in China; demographic characteristics, smoking history, occupational exposure, biomass exposure, lung function, dyspnea, quality of life, and prescriptions for inhaled medications were collected. The nearest neighbor algorithm was used to match female and male patients (ratio 2:1) on age, body mass index, and lung function. RESULTS Compared with 1462 men, the 731 women generally had lower educational levels and were married less (both p < 0.001). A total of 576 (90.0%) women did not smoke cigarettes. More men were exposed to occupational dust (539 (36.9%) vs. 84 (11.5%), p = 0.013), while more women were exposed to biomass smoke (330 (45.1%) vs. 392 (26.8%), p = 0.004). Except for phlegm and chest tightness, women had more complaints than men for cough, breathlessness, activities, confidence, sleep and energy (p < 0.05). In addition, more women were prescribed triple therapy than men (236 (36.3%) vs. 388 (31.0%), p = 0.020). CONCLUSIONS There are obvious discrepancies in the quality of life and use of inhaled medications between male and female patients with COPD.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a physical and mental disease, and there is currently no cure, so the health guidance of COPD patients after discharge from hospital is crucial. The purpose of this study is to investigate the nursing outcomes and risk factors for patients with COPD discharged from hospital. METHODS In this study, a total of 200 patients with COPD who were stable and ready to be discharged from two tertiary hospitals in Taiyuan were surveyed by the Nursing Outcome Evaluation Form for COPD patients, and the relevant risk factors of these patients were analysed. RESULTS The results of this study showed that patients with COPD who were to be discharged from hospital had low scores in the perceived health domain (1.9708 ± 0.70525) and psychosocial health domain (1.5267 ± 0.68289), while the scores in the rest of the domains were above the medium level. The main factors affecting the two domains of the nursing outcome were degree of education, dietary habits, complications (perceived health domain), drinking, marital status, medical insurance and smoking (psychosocial health domain) (p < 0.05). CONCLUSION Clinical nurses should pay attention to the perceived and psychosocial health domains when educating COPD patients who are to be discharged from hospital, and should primarily focus on the risk factors of smoking and drinking status, degree of education, dietary habits, complications, marital status and medical insurance.

Real-World Effectiveness of Inhalation Therapy Among Patients With Symptomatic COPD in China: A Multicenter Prospective Study. Front Pharmacol 2021; 12:753653. [PMID: 34621178 PMCID: PMC8490668 DOI: 10.3389/fphar.2021.753653] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 09/09/2021] [Indexed: 01/11/2023] Open
Abstract
Purpose: This real-world study evaluated the effectiveness of different inhalation therapies in patients with symptomatic chronic obstructive pulmonary disease (COPD) in China and also explored the relevant factors that influence the effectiveness of inhalation therapy. Patients and Methods: We conducted a multicenter prospective longitudinal study that was carried out in 12 hospitals in China from December 2016 to June 2021. A face-to-face interview was conducted to collect data. Baseline data were collected at the first visit. Minimum clinically important difference (MCID) was defined as attaining a COPD assessment test (CAT) decrease ≥2. We mainly assessed the MCID and the incidence of exacerbations at the 6 months follow-up. Results: In 695 patients, the mean age was 62.5 ± 8.2 years, with a mean CAT score of 15.1 ± 6.0. Overall, 341 (49.1%) patients attained the MCID of CAT and the incidence of exacerbation during follow-up was 22.3%. Females were significantly more likely to attain MCID than male in COPD patients (adjusted odd ratio (aOR) = 1.93, adjusted 95% confidence interval (a95%CI) = 1.09–3.42, p = 0.024). Patients treated with LABA/LAMA or ICS/LABA/LAMA (ICS, inhaled corticosteroid; LABA, long-acting β2-agonist; LAMA, long-acting muscarinic antagonist) were more likely to attain MCID than patients treated with LAMA (aOR = 3.97, a95%CI = 2.48–6.35, p < 0.001; aOR = 3.17, a95%CI = 2.09–4.80, p < 0.001, respectively). Patients treated with LABA/LAMA had a higher incidence of severe exacerbation than patients treated with ICS/LABA/LAMA (aOR = 1.95, a95%CI = 1.04–3.66, p = 0.038). Conclusion: The incidence of MCID in symptomatic COPD patients treated with inhalation therapy was nearly 50%. Patients treated with LABA/LAMA or ICS/LABA/LAMA were more likely to attain MCID than patients treated with LAMA. Patients treated with LABA/LAMA had a higher incidence of severe exacerbations than with ICS/LABA/LAMA.

Int J Chron Obstruct Pulmon Dis 2021; 16:2697-2706. [PMID: 34611398 PMCID: PMC8485917 DOI: 10.2147/copd.s327686] [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: 07/03/2021] [Accepted: 09/13/2021] [Indexed: 11/23/2022] Open
Abstract
Background Pneumoconiosis has high prevalence of chronic obstructive pulmonary disease (COPD), respiratory morbidity, and mortality. Objective The aim of the present study was to examine patient characteristics and adherence to inhaled therapy among pneumoconiosis with COPD in a real-world clinical setting. Methods A cohort of pneumoconiosis patients with COPD prescript with at least one type of long-acting inhaled drug was followed for adherence for 2 years. Demographic and COPD-related characteristics were collected in baseline. Results In baseline, after adjusting for age, dust exposure duration positively correlated with number of acute exacerbation (AE) frequency in the last year. There were close associations among COPD Assessment Tool (CAT) score, modified Medical Research Council Dyspnea Scale (mMRC) grade, number of AE, and pre-FEV1 value. Of 296 participants originally recruited, 213 participants finished the 2-year follow-up for adherence. 122 (57.28%) were non-adherent to inhaled therapy. The most common reason for non-adherence was “relief of symptoms after short-term controller medication use” (53.28%). Patients who were non-adherent reported higher body mass index (BMI), less AE events in the last year, higher pre-FEV1 value, higher post-FEV1 value and low CAT, mMRC scores compared to adherent in baseline. High pre-FEV1 value (OR = 1.04, CI = 1.018–1.064) and low mMRC scores (OR = 0.406, CI = 0.214–0.771) were risk factors found associated with non-adherence. Conclusion A majority of pneumoconiosis patients complicated with COPD have suboptimal inhaled therapy adherence. Evidence-based, adherence-enhancing interventions should be targeted on less severe subjects.

Int J Chron Obstruct Pulmon Dis 2021; 16:1401-1412. [PMID: 34040367 PMCID: PMC8143960 DOI: 10.2147/copd.s309267] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Accepted: 05/04/2021] [Indexed: 11/23/2022] Open
Abstract
Background The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 separated pulmonary function from combined assessment. We aimed to analyze the characteristics of airflow limitation and future exacerbations in different GOLD groups of chronic obstructive pulmonary disease (COPD) patients. Methods For this prospective observational study, stable COPD outpatients were enrolled and divided into Groups A, B, C and D based on GOLD 2017, and followed-up for 18 months. Data on demographics, pulmonary function, COPD assessment test (CAT), Clinical COPD Questionnaire (CCQ), modified Medical Research Council (mMRC), exacerbations, mortality and treatments were collected. A post-bronchodilator ratio of forced expiratory volume in one second to forced vital capacity <0.70 confirms the presence of airflow limitation. Results A total of 993 subjects were classified into Groups A (n = 170, 17.1%), B (n = 360, 36.3%), C (n = 122, 12.3%), and D (n = 341, 34.3%). There were significant differences in mMRC, CAT, CCQ, exacerbations and hospitalizations rates among the different groups (P < 0.001). Groups B and D had more severe airflow limitation than Groups A and C (P < 0.05). In the same groups with different severity of airflow limitation, the differences were mainly observed in body mass index, CAT, CCQ and treatment with long-acting muscarinic antagonist (LAMA) and LAMA + long-acting β2-agonist + inhaled corticosteroid (P < 0.05). After 18 months of follow-up, the exacerbations and hospitalizations rates were significantly different among different groups (P < 0.05). However, in the same groups with different airflow limitation severity, the mortality rates and number of exacerbations, hospitalizations and frequent exacerbators showed no differences. Conclusion In the GOLD groups, different severity of airflow limitation had no impact on future exacerbations and mortality rate. It implies that pulmonary function is not a good indicator for predicting exacerbation.
