Objective. To compare frequency of echocardiographic changes in patients with chronic obstructive pulmonary disease (COPD) and non-COPD controls and to assess their relation to the level of airflow limitation. Methods. Study population included 120 subjects divided in two groups. Group 1 included 60 patients with COPD (52 male and 8 female, aged 40 to 80 years) initially diagnosed according to the actual recommendations. Group 2 included 60 subjects in whom COPD was excluded serving as a control. The study protocol consisted of completion of a questionnaire , pulmonary evaluation (dyspnea severity assessment, baseline and post-bronchodilator spirometry, gas analyses, and chest X-ray) and two dimensional (2D) Doppler echocardiography. Results. We found significantly higher mean right ventricle end-diastolic dimension (RVEDd) in COPD patients as compared to its dimension in controls (28.0 ± 4.8 vs. 24.4 ± 4.3; P = 0.0000). Pulmonary hypertension (PH) was more frequent in COPD patients than in controls (28.0 ± 4.8 vs. 24.4 ± 4.3; P = 0.0000) showing linear relationship with severity of airflow limitation. The mean value of left ventricular ejection fraction (LVEF%) was significantly lower in COPD patients than its mean value in controls (57.4 ± 6.9% vs. 64.8 ± 2.7; P = 0.0000) with no correlation with severity of airflow limitation.       Conclusion. Frequency of echocardiographic changes in COPD patients was significantly higher as compared to their frequency in controls in the most cases being significantly associated with severity of airflow limitation. Echocardiography enables early, noninvasive, and accurate diagnosis of cardiac changes in COPD patients giving time for early intervention. Key words: airflow limitation, chronic obstructive pulmonary disease, Doppler echocardiography, pulmonary hypertension, ventricular dysfunction.

Background: Patients with chronic obstructive pulmonary disease (COPD) are at risk for pulmonary hypertension (PH). The aim of our study was to investigate the benefit of statins for PH in patients with COPD.Methods: The study enrolled 23 million individuals from Taiwan’s population database from January 1, 2002, to December 31, 2017. COPD patients who met the inclusion criteria were enrolled, and patients with lung cancer, less than one year of observation, specific drug therapy for PH and lung transplantation were excluded.Results: A total of 643,131 COPD patients were included in the study, and only 12,308 patients developed PH during follow-up. Based on the inclusion and exclusion criteria, 8,577 PH patients were included in the cohort of patients with PH related to COPD for analysis. According to the definition of statin exposure, the final study population had 1,487 statin users and 7,090 statin non-users. The statin user group had a lower mortality related to PH than the non-user group (3.87 vs. 5.55 per 100 person-years, p < 0.001). The mortality rate for PH in the multivariate analysis (aHR = 0.78, 95% CI = 0.62–0.98, p = 0.046) was significantly lower for statin users than for non-users.Conclusion: Statins seem to benefit patients with PH and COPD.

Co Morbidity

Background: Chronic obstructive pulmonary disease (COPD) is a common preventable and treatable disease that is characterised by persistent respiratory symptoms and airflow limitation. COPD is characterised by an intense inflammatory process in the airways, parenchyma, and pulmonary vasculature. It is possible in some cases that the inflammatory process may overflow into the systemic circulation, promoting a generalised inflammatory reaction. Patient with COPD often have concomitant chronic illness (co-morbidities). The aim of this study is to know the pattern of co-morbidities in COPD patients.Methods: This study was a cross sectional observational study conducted on 172 COPD patients (IPD and OPD) diagnosed on the basis of GOLD guideline 2017. Co morbidities were diagnosed as per standard defined criteria laid down in the respective guidelines.Results: 55.3% of the patients with COPD had co morbidities. 18/88(20.5%) patients presented with multiple co-morbidities. 49/88, 55.7% COPD patients were affected with cardiac (either only cardiac or had multiple organs affected besides cardiac), the commonest co-morbidity. Amongst cardiac, hypertension and congestive heart failure (CHF) was the commonest (n=19/49, 38.8% each) followed by CAD/CSA/IWMI/IHD/AF. Others were metabolic (n=14/88, 15.9%), GERD (n=13/88, 14.8%), Depression (n=11/88, 12.5%). Less prevalent co-morbidities were Osteoporosis (n=8/88, 9.1%), Lung cancer (n=6/88, 6.8%), Bronchiectasis (n=5/88, 5.6%) and OSA (n=3/88, 3.4%).Conclusions: Urban indwelling, advancing age and duration of illness, presentation with low mood, loss of pleasure/ interest, appetite disturbances and heart burn with relief on taking proton pump inhibitor can be predictors of co-morbidities in COPD patients. Chance of finding co-morbidities may be multifactorial. Thus, it is important to look out for co morbidities in each and every COPD patients.

Background and Aims: Chronic obstructive pulmonary disease (COPD) is highly prevalent in the Nepalese population. It is associated with significant extrapulmonary effects among which cardiovascular complications are most common. Echocardiography evaluation mainly focused on effects on the right heart function is a salient tool to evaluate the presence of degree of pulmonary hypertension and also identify those group of patients who need more early aggressive therapy for the underling lung disease . We aimed to prospectively study the patients with diagnosed COPD with echocardiogram for evaluating the right heart.Methods: An observational, cross sectional study was done on 50 patients with COPD who were admitted at Bir Hospital and underwent echocardiographic evaluation from Dec 2015 –Dec 2016. All echocardiogaphic parameters focused on right heart and its function were assessed .Results: Out of total 50 COPD patients studied, majority of them were female (32 patients. 64%). The mean age group of the studied patients was 60.9 ±11.4 years. Pulmonary hypertension defined as sPAP>30 mmHg was evident in all of the patients ; with 30 patients (60% ), 14 (28 %) and 6(12 %) patients having severe, moderate and mild pulmonary hypertension respectively. RV dysfunction was evident with reduced average TAPSE values (1.59± 0.38 cm) and elevated RIMP values (0.58±0.16).Conclusion: Majority of COPD patients had evidence of pulmonary hypertension. Echocardiogram can be a helpful tool to assess early changes on the right heart size and function in patients with COPD and also monitor these patients for rapid progression of the illness.Nepalese Heart Journal 2017; Vol 14(2), 9-12

Carboxymethyl Lysine

It has been reported that small airway inflammation is closely associated with the severity of airflow limitation in COPD (chronic obstructive pulmonary disease). We tested a new method of measurement of biochemical constituents in ELF (epithelial lining fluid) obtained separately from the central or peripheral airways using a bronchoscopic microsampling technique. The present study was designed to determine the validity of measuring CML [Nε-(carboxymethyl)lysine] levels in ELF for the assessment of small airway inflammation in COPD. Ten non-smokers, ten current smokers and 16 COPD patients were included in the present study. Concentrations of CML, 8-isoprostane and IL-8 (interleukin-8) were measured in ELF separately from the central or peripheral airways. CML levels in central airways did not differ significantly, but were markedly higher in peripheral than in central airways in the three groups. However, CML levels in peripheral airways of COPD patients were significantly higher than those in non-smokers and current smokers. In COPD patients, the CML level in peripheral airways was significantly correlated with FEV1 (forced expiratory volume in 1 s) (r=−0.82, P=0.002) and FEV1/FVC (forced vital capacity) (r=−0.57, P=0.03). Moreover, CML levels in peripheral airways were significantly correlated with levels of both 8-isoprostane (r=0.76, P=0.003) and IL-8 (r=0.67, P=0.01). In conclusion, these findings suggest that elevated levels of CML in ELF from peripheral airways were observed in COPD patients, and this parameter was correlated with the severity of airflow limitation.

Background: Chronic obstructive pulmonary disease is preventable and treatable disease with progressive persistent airflow limitation and enhanced chronic inflammatory response in the airways. Indian council of medical research conducted a study and found that total burden of COPD in India has more than doubled to about 14.84 million in 2011 from about 6.45 million in 1971Methods: It was an open label cross sectional study. It was conducted on patients attending the outpatient department of respiratory medicine, new medical college and hospital, Kota, over a period of one year. 100 COPD patients attending the respiratory outpatient department of GMC, Kota and fulfilling the inclusion criteria’s were included in the study. A diagnosis and severity of COPD was established by clinical symptoms and spirometric data as per GOLD guideline (ratio of FEV1 and forced vital capacity <0.7).Results: We found a significant negative correlation (Pearson correlation coefficient r = -0.664, p< 0.001) between 6 MWD and BODE index in study population.Conclusions: Thus, we concluded that the functional exercise capacity of COPD patients measured by 6MWT deteriorates linearly with severity of the disease assessed by the GOLD staging criteria. Hence we can use 6 MWT for assessing the severity of COPD in place of spirometry where the facility of spirometry is not feasible.

Background: Chronic Obstructive Pulmonary Disease (COPD) is a global health burden having systemic and extrapulmonary manifestations. Among them cardiovascular changes are the major comorbidity associated with COPD, responsible for significant morbidity and mortality. Echocardiography is one of the simplest and noninvasive tools in assessing these changes. Objective: To evaluate the echocardiographic changes in patients with chronic obstruction palmonary disease. Methods: A cross sectional observational study was carried out in Department of Cardiology and Department of Respiratory Medicine, Dhaka Medical College Hospital from July, 2018 to June, 2019. Total 98 COPD patients were included in the study. They underwent spirometry in Department of Respiratory Medicine and echocardiography in Department of Cardiology. Data was collected from the patients and recorded in a structured report form. Results: Significant echocardiographic abnormalities were present in 51.02% patients. Most common echocardiographic change was pulmonary hypertension (43.9%). Other echocardiographic findings were dilated RA & RV (36.7%), RVH (35.7%), LV diastolic dysfunction (30.6%) and RV systolic dysfunction (9.2%). Echocardiographic signs of pulmonary hypertension, dilated RA & RV, RVH, RV systolic dysfunction and LV diastolic dysfunction were correlated with the severity of the disease. Though echocardiographic change of pulmonary hypertension was uncommon in COPD stage 1 & 2, but it was very common in stage 3(45.7%) & stage 4(92.9%). Conclusion: This study showed that echocardiographic changes were very common among the COPD GOLD stage 3 & 4 patients. Though these changes were infrequent among mild COPD patients but their severity increased with increasing stage of COPD. Bangladesh Med Res Counc Bull 2020; 46(3): 204-210

Exacerbation Risk

To achieve a multidimensional evaluation of chronic obstructive pulmonary disease (COPD) patients, the spirometry measures are supplemented by assessment of symptoms, risk of exacerbations, and CT imaging. However, the measurement of diffusing capacity of the lung for carbon monoxide (DLCO) is not included in most common used models of COPD assessment. Here, we conducted a meta-analysis to evaluate the role of DLCO in COPD assessment. The studies were identified by searching the terms “diffusing capacity” OR “diffusing capacity for carbon monoxide” or “DLCO” AND “COPD” AND “assessment” in Pubmed, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Scopus, and Web of Science databases. The mean difference of DLCO % predict was assessed in COPD patient with different severity (according to GOLD stage and GOLD group), between COPD patients with or without with frequent exacerbation, between survivors and non-survivors, between emphysema dominant and non-emphysema dominant COPD patients, and between COPD patients with or without pulmonary hypertension. 43 studies were included in the meta-analysis. DLCO % predicted was significantly lower in COPD patients with more severe airflow limitation (stage II/IV), more symptoms (group B/D), and high exacerbation risk (group C/D). Lower DLCO % predicted was also found in exacerbation patients and non-survivors. Low DLCO % predicted was related to emphysema dominant phenotype, and COPD patients with PH. The current meta-analysis suggested that DLCO % predicted might be an important measurement for COPD patients in terms of severity, exacerbation risk, mortality, emphysema domination, and presence of pulmonary hypertension. As diffusion capacity reflects pulmonary ventilation and perfusion at the same time, the predictive value of DLCO or DLCO combined with other criteria worth further exploration.

Mass Spectrometry Identification

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by airflow limitation. This chronic respiratory disease represents the third leading cause of death worldwide. Alteration of the airway microbiota has been reported to be associated with exacerbation frequency in COPD, but its role on the symptoms in patients at stable state is still incompletely described. This study aimed to determine whether bacteria isolated in sputum can be associated with the clinical features of COPD patients within stable state. Our study highlights, for the first time, that altered microbiota with Enterobacterales is associated with pejorative clinical symptoms in stable COPD patients. The airway microbiota of 38 patients was analyzed using an extended culture approach and mass spectrometry identification. Cluster analysis by principal coordinate analysis of the bacterial communities showed that the patients could be classified into three distinct clusters in our cohort. The clusters showed no differences in proportions of the phylum, but one of them was associated with a high prevalence of Enterobacterales (71.4% in cluster 1 vs. 0% in cluster 3), loss of microbiota diversity, and higher bacterial load (107 vs. 105 CFU/ml, respectively) and characterized by predominant cough and impact on mental health. These novel findings, supported by further studies, could lead to modifying the processing of COPD sputum in the everyday practice of clinical microbiology laboratories.

Abstract Extracellular adenosine triphosphate (eATP)-driven inflammation was observed in chronic obstructive pulmonary disease (COPD) but was not investigated in patients’ blood. Therefore, this study aimed to investigate eATP concentration in plasma of COPD patients and its association with disease severity and smoking. Study included 137 patients with stable COPD and 95 control subjects. eATP concentration was determined in EDTA plasma by luminometric method, and mRNA expression of eATP receptors P2X7R and P2Y2R was analysed by quantitative polymerase chain reaction (qPCR). eATP concentration was increased in COPD patients compared to controls (P < 0.001). Moreover, it was increasing with disease severity (GOLD 2–4) as well as symptoms burden and exacerbations history (GOLD A–D) (P < 0.05). eATP in healthy smokers differed from healthy non-smokers (P < 0.05) but was similar to GOLD 2 and GOLD A patients. eATP showed great diagnostic performances (OR = 12.98, P < 0.001) and correctly classified 79% of study participants. It demonstrated association with FEV1 and multicomponent indices (ADO, BODEx, BODCAT, CODEx, DOSE). Regarding gene expression, P2Y2R was increased in the blood of COPD patients. Plasma eATP could become a diagnostic and/or prognostic biomarker in COPD, as it seems to be associated with patients’ condition, quality of life and disease progression.
