Background: Chronic obstructive pulmonary disease is the fourth leading cause of mortality worldwide. It is defined as a disease state characterized by airflow limitation that is not fully reversible. Patients with chronic obstructive pulmonary disease (COPD) are at increased risk of cardiovascular disease. Electrocardiography (ECG) carries information about cardiac disease and prognosis in COPD patients. Present study was undertaken to correlate ECG changes with severity of COPD.Methods: 100 patients of COPD fulfilling the inclusion criteria coming to OPD/wards of NMCH, Kota were recruited. They were staged by pulmonary function test (PFT) and evaluated by electrocardiography. Statistical analysis of correlation was done with chi square test and statistical significance was taken p<0.05.Results: Mean age was 63.18±8.66 years, with male preponderance, male to female ratio 6.14:1. Mean duration of disease was 7.58±2.92 years, mean exposure to smoking of 25.06 pack years. Most common ECG finding was RAD which was present in 69% of cases, other ECG findings are P. pulmonale (45%), incomplete RBBB (15%), PPRW (35%), RVH (53%). All ECG findings except incomplete RBBB significantly correlated with disease severity (‘p’ value <0.05).Conclusions: COPD is more common in male in 5th to 7th decade of life, with a smoking history of more than 20 pack years. The occurrence of ECG findings increase as severity and duration of disease increase. It can be inferred that ECG is a useful bedside test to assess the severity of COPD.

Background: Chronic obstructive pulmonary disease is the fourth leading cause of mortality worldwide. It is defined as a disease formal categorized by airflow limitation that is not fully reversible. Patients with chronic obstructive pulmonary disease (COPD) are at increased risk of cardiovascular disease. Electrocardiography (ECG) carries information about cardiac disease and prognosis in COPD patients. However, Echocardiography provides a rapid, noninvasive, portable, and accurate method to evaluate cardiac functions.Methods: A 100 patients of COPD fulfilling the inclusion criteria coming to OPD/wards of Medicine, Gitanjali medical college and Hospital, Udaipur were recruited. They were staged by pulmonary function test (PFT) and evaluated by electrocardiography and echocardiography. Statistical analysis of correlation was done with chi square test and statistical significance was taken p<0.05.Results: Mean age was 52.54±9.55 years, with male preponderance, male to female ratio 4.55:1. Mean duration of disease was 6.36±4.14 years. The common symptoms were Breathlessness (100%). Most common ECG and ECHO finding was RAD (52%) and PAH (54%) respectively. Statistically Right axis deviation and Poor ‘r’ wave progression was significantly correlated with disease severity by ECG findings while R.A. dilatation, R.V. dilatation and Pulmonary hypertension were significantly correlated with disease severity by ECHO findings (p<0.05).Conclusions: COPD is more common in males and in the 5th and 6th decade of life. Most of the patients have fairly advanced disease at presentation. The incidence of abnormalities of ECG and echocardiography increases with COPD severity. ECG and echocardiography are better tools than clinical methods in detecting R.V. dysfunction in COPD.

The Impact

Chronic obstructive pulmonary disease (COPD) is a chronic disease characterized by a progressive decline in lung function due to airflow limitation, mainly related to IL-1β-induced inflammation. We have hypothesized that single nucleotide polymorphisms (SNPs) in NLRP genes, coding for key regulators of IL-1β, are associated with pathogenesis and clinical phenotypes of COPD. We recruited 704 COPD individuals and 1238 healthy controls for this study. Twenty non-synonymous SNPs in 10 different NLRP genes were genotyped. Genetic associations were estimated using logistic regression, adjusting for age, gender, and smoking history. The impact of genotypes on patients’ overall survival was analyzed with the Kaplan–Meier method with the log-rank test. Serum IL-1β concentration was determined by high sensitivity assay and expression analysis was done by RT-PCR. Decreased lung function, measured by a forced expiratory volume in 1 s (FEV1% predicted), was significantly associated with the minor allele genotypes (AT + TT) of NLRP1 rs12150220 (p = 0.0002). The same rs12150220 genotypes exhibited a higher level of serum IL-1β compared to the AA genotype (p = 0.027) in COPD patients. NLRP8 rs306481 minor allele genotypes (AG + AA) were more common in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) definition of group A (p = 0.0083). Polymorphisms in NLRP1 (rs12150220; OR = 0.55, p = 0.03) and NLRP4 (rs12462372; OR = 0.36, p = 0.03) were only nominally associated with COPD risk. In conclusion, coding polymorphisms in NLRP1 rs12150220 show an association with COPD disease severity, indicating that the fine-tuning of the NLRP1 inflammasome could be important in maintaining lung tissue integrity and treating the chronic inflammation of airways.

Introduction: The association of chronic obstructive pulmonary disease and pulmonary tuberculosis is an important medical and social problem with a significant burden in terms of morbidity and mortality. The course and prognosis of chronic diseases such as chronic obstructive pulmonary disease and pulmonary tuberculosis is greatly influenced not only by the clinical features but also by the psychological characteristics of the patient. The aim: To study the interaction between clinical changes and psychological characteristics considering gender differences among patients with chronic obstructive pulmonary disease in association with pulmonary tuberculosis. Materials and methods: We studied 41patients with chronic obstructive pulmonary disease (grade 2, 3, groups А, B, С, D) and infiltrative pulmonary tuberculosis co-morbidity (11 women and 30 men). All patients underwent general clinical examination, Acid-Fast Bacillus Testing, spirometry, Spielberg anxiety scale, Beck depression scale. Results: Patients with chronic obstructive pulmonary disease and pulmonary tuberculosis co-morbidity with more severe symptoms (according to Assesment Test scores) were older and, regardless of it, showed elevated depression and personal anxiety scores while situational anxiety scores were significantly lower compared to those with less severe symptoms. The correlation between symptoms severity and airflow limitation or smoking history was very mild. The elevated depression and personal anxiety could cause more severe symptoms. The revealed discrepancy between the symptoms severity and low levels of situational anxiety may be due to adaptation with displacement mechanisms to illness related chronic life stressors. We also observed elevated personal anxiety and depression scores together with less severe symptoms among female versus male chronic obstructive pulmonary disease/pulmonary tuberculosis patients, possibly reflecting physically ill women’s higher risk for depressive and anxiety related symptomatology relative to ill men. Conclusions: We revealed that among patients with chronic obstructive pulmonary disease and pulmonary tuberculosis co-morbidity symptoms severity was largely influenced by the patients’ age, gender and psychological factors (depression and personal anxiety), but, unexpectedly, much less – by airflow limitation and smoking history. We also found higher emotional distress, namely elevated personal anxiety and depression scores, in combination with less severe symptoms among female versus male patients with chronic obstructive pulmonary disease and pulmonary tuberculosis co-morbidity.

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.

Aim: To detect the right ventricular status by echocardiography of COPD patients.Background: Chronic obstructive pulmonary disease is an increasing cause of chronic morbidity and mortality worldwide. Smoking is the major cause and the patients consult with physicians very much late when become complicated. Echocardiography is the main determinant of outcome of COPD patient. We can assess the level of pulmonary hypertension which leads to right heart failure.Methods : This is a cross sectional study. Study place was Department of Medicine, Rangpur Medical College from 1st July to 30 September 2014.Clinically and post bronchodilator Spiro metrically diagnosed cases were taken. Patients were graded into Mild, Moderate, severe and very severe categories according to GOLD criteria. Statistical analysis was done with echo findings of RV dilatation and hypertrophy by using Chi-square test and statistical significance was taken as p < 0.05Results : Mean age was 61.50 (sd±9.76) years with male predominance. Mean duration of disease was 6.80 ( sd ± 4.71) years. Patients had a mean duration of smoking of 23.2 ±3.6 pack years. ECG and Echo findings such as RV dilatation, RV hypertrophy and pulmonary hypertension were showed significant correlation with severity and duration of disease. Diagnosis of cor-pulmonale was clinically 20%, ECG 50% and echocardiographically 92%.Conclusion : COPD is more common in males in 5th to 7th decade with the smoking history of more than 20 pack years. Most patients have moderate to severe disease at presentation. Echocardiography can detect the RV dysfunction in COPD patient earlier. ECG and Echo findings increase as the severity and duration of the disease increases and echocardiography is better than ECG or clinical methods in detecting RV dysfunction.Bangladesh J Medicine Jul 2018; 29(2) : 63-68

Similarities And Differences

Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease that is associated with significant morbidity and mortality, giving rise to an enormous social and economic burden. The Global Strategy for the Diagnosis, Management and Prevention of Chronic Obstructive Pulmonary Disease (GOLD) report is one of the most frequently used documents for managing COPD patients worldwide. A survey was conducted across country-level members of Asia-Pacific Society of Respiratory (APSR) for collecting an updated version of local COPD guidelines, which were implemented in each country. This is the first report to summarize the similarities and differences among the COPD guidelines across the Asia-Pacific region. The degree of airflow limitation, assessment of COPD severity, management, and pharmacologic therapy of stable COPD will be reviewed in this report.

BACKGROUNDBronchodilator reversibility testing is recommended in all patients with chronic obstructive pulmonary disease (COPD) but does not predict improvements in breathlessness or exercise performance. Two alternative ways of assessing lung mechanics—measurement of end expiratory lung volume (EELV) using the inspiratory capacity manoeuvre and application of negative expiratory pressure (NEP) during tidal breathing to detect tidal airflow limitation—do relate to the degree of breathlessness in COPD. Their usefulness as end points in bronchodilator reversibility testing has not been examined.METHODSWe studied 20 patients with clinically stable COPD (mean age 69.9 (1.5) years, 15 men, forced expiratory volume in one second (FEV1) 29.5 (1.6)% predicted) with tidal flow limitation as assessed by their maximum flow-volume loop. Spirometric parameters, slow vital capacity (SVC), inspiratory capacity (IC), and NEP were measured seated, before and after nebulised saline, and at intervals after 5 mg nebulised salbutamol and 500 μg nebulised ipratropium bromide. The patients attended twice and the treatment order was randomised.RESULTSMean FEV1, FVC, SVC, and IC were unchanged after saline but the degree of tidal flow limitation varied. FEV1 improved significantly after salbutamol and ipratropium (0.11 (0.02) l and 0.09 (0.02) l, respectively) as did the other lung volumes with further significant increases after the combination. Tidal volume and mean expiratory flow increased significantly after all bronchodilators but breathlessness fell significantly only after the combination treatment. The initial NEP score was unrelated to subsequent changes in lung volume.CONCLUSIONSNEP is not an appropriate measurement of acute bronchodilator responsiveness. Changes in IC were significantly larger than those in FEV1and may be more easily detected. However, our data showed no evidence for separation of “reversible” and “irreversible” groups whatever outcome measure was adopted.

Inspiratory Muscle Strength

Staging criteria for COPD (chronic obstructive pulmonary disease) include symptoms and lung function parameters, but the role of reduced inspiratory muscle strength related to disease severity remains unclear. Therefore the present study tested whether inspiratory muscle strength is reduced in COPD and is related to disease severity according to GOLD (Global Initiative for Chronic Obstructive Lung Disease) criteria and assessed its clinical impact. PImax (maximal inspiratory mouth occlusion pressure), SnPna (sniff nasal pressure) and TwPmo (twitch mouth pressure) following bilateral anterior magnetic phrenic nerve stimulation were assessed in 33 COPD patients (8 GOLD0, 6 GOLDI, 6 GOLDII, 7 GOLDIII and 6 GOLDIV) and in 28 matched controls. Furthermore, all participants performed a standardized 6 min walking test. In comparison with controls, PImax (11.6±2.5 compared with 7.3±3.0 kPa; P<0.001), SnPna (9.7±2.5 compared with 6.9±3.3 kPa; P<0.001) and TwPmo (1.6±0.6 compared with 0.8±0.4 kPa; P<0.001) were markedly lower in COPD patients. TwPmo decreased with increasing COPD stage. TwPmo was correlated with walking distance (r=0.75; P<0.001), dyspnoea (r=−0.61; P<0.001) and blood gas values following exercise (r>0.57; P<0.001). Inspiratory muscle strength, as reliably assessed by TwPmo, decreased with increasing severity of COPD and should be considered as an important factor in rating disease severity and to reflect burden in COPD.

Stage 1

Chronic obstructive pulmonary disease (COPD) is characterized by a decline in forced expiratory volume in 1 s (FEV1) and, in many advanced patients, by arterial hypoxemia with or without hypercapnia. Spirometric and gas exchange abnormalities have not been found to relate closely, but this may reflect a narrow range of severity in patients studied. Therefore, we assessed the relationship between pulmonary gas exchange and airflow limitation in patients with COPD across the severity spectrum. Ventilation-perfusion (V̇A/Q̇) mismatch was measured using the multiple inert gas elimination technique in 150 patients from previous studies. The distribution of patients according to the GOLD stage of COPD was: 15 with stage 1; 40 with stage 2; 32 with stage 3; and 63 with stage 4. In GOLD stage 1, AaPo2 and V̇A/Q̇ mismatch were clearly abnormal; thereafter, hypoxemia, AaPo2, and V̇A/Q̇ imbalance increased, but the changes from GOLD stages 1–4 were modest. Postbronchodilator FEV1 was related to PaO2 ( r = 0.62) and PaCO2 ( r = −0.59) and to overall V̇A/Q̇ heterogeneity ( r = −0.48) ( P < 0.001 each). Pulmonary gas exchange abnormalities in COPD are related to FEV1 across the spectrum of severity. V̇A/Q̇ imbalance, predominantly perfusion heterogeneity, is disproportionately greater than airflow limitation in GOLD stage 1, suggesting that COPD initially involves the smallest airways, parenchyma, and pulmonary vessels with minimal spirometric disturbances. That progression of V̇A/Q̇ inequality with spirometric severity is modest may reflect pathogenic processes that reduce both local ventilation and blood flow in the same regions through airway and alveolar disease and capillary involvement.
