AbstractThis study aims to investigate the characteristics of the phenotype and management of chronic obstructive pulmonary disease (COPD) patients in the general population in China. We analyzed spirometry-confirmed COPD patients who were identified from a population-based, nationally representative sample in China. All participants were measured with airflow limitation severity based on post-bronchodilator FEV1 percent predicted, bronchodilator responsiveness, exacerbation history, and respiratory symptoms. Among a total of 9134 COPD patients, 90.3% were non-exacerbators, 2.9% were frequent exacerbators without chronic bronchitis, 2.0% were frequent exacerbators with chronic bronchitis, and 4.8% were asthma-COPD overlap. Less than 5% of non-exacerbators ever had pulmonary function testing performed. The utilization rate of inhaled medication in non-exacerbators, exacerbators without chronic bronchitis, exacerbators with chronic bronchitis, and asthma-COPD overlap was 1.4, 23.5, 29.5, and 19.4%, respectively. A comprehensive strategy for the management of COPD patients based on phenotype in primary care is urgently needed.

Introduction: Chronic Obstructive Pulmonary Disease (COPD) is characterised by persistent airflow limitation and is a global health issue with high social and economic burden. Type 2 Diabetes Mellitus (T2DM) is a major global metabolic disorder affecting approximately 300 million individuals worldwide. Accordingly, chronic low grade systemic inflammation is probably one of the common denominators between COPD and T2DM. Aim: To evaluate the status of systemic inflammation in COPD patient with/without T2DM, using quantitative serum high sensitivity C-Reactive Protein (hs-CRP) and Total Leucocyte Count (TLC). Materials and Methods: This cross-sectional study was conducted for a period of one year from May 2019 to April 2020 on 100 patients of COPD patients attending outpatient department. Either known patients of COPD or patients with complains of chronic cough was evaluated with chest x-ray and pulmonary function test (spirometry) after thorough history and physical examination. Global Initiative for Chronic Obstructive Lung Disease-GOLD guidelines a grading system for COPD was used for assessing severity. For assessing diabetes, criteria adopted from American Diabetes Association (ADA) i.e., symptoms of diabetes plus random plasma glucose >200 mg/dL (11.1 mMol/L). Venous blood samples were obtained to perform quantitative hs-CRP estimation by immune turbidimetry method as a marker of systemic inflammation. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) version 26.0 of International Business Machines (IBM) Corporation, California, United States of America (USA). Results: The T2DM was present in 40% COPD patients. The frequencies of T2DM in patients with GOLD stages I, II, III, and IV were 16%, 45%, 28%, and 11%, respectively. The mean hs-CRP levels for diabetic group was 5.45±1.07 mg/L, which was significantly higher (p<0.05) than 2.26±0.69 mg/L that of non diabetic group. Conclusion: Present study concluded that the inflammatory process is a definite pathophysiological factor that has a significant link between COPD and T2DM and can be evaluated using a marker like hs-CRP level and TLC.

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.

Chronic Inflammatory Response

Abstract Background Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation associated with an enhanced chronic inflammatory response in the airway, acute exacerbations of COPD can lead to progressive respiratory failure necessitating mechanical ventilation. Weaning of these patients may prove difficult and a spontaneous breath trial should be provided before the decision of extubation. Aim To evaluate the role of capnograghy in COPD patients during weaning from mechanical ventilation. Subject and methods This was a cross sectional prospective study conducted on 50 patients who were admitted at the Respiratory Intensive Care Unit of Abbassia Chest hospital and diagnosed as COPD and on mechanical ventilation. During the weaning trial, the role of capnography device evaluated considering the ability of Pet CO2 parameter in predicting hypercapnia and subsequently weaning outcome Results The changes in ABG reading before and after the SBT, PaCO2 and Pet CO2 showed significant elevation at the end of SBT,P=0.001 for both, while O2 saturation was significantly decrease at the end of SBT, P0.001. Conclusion The study found that Pa CO2 and PetCO2 are correlated to each other before, during and after SBT. Most of the studies that was found reported that PetCO2 is highly correlated with Paco2 and that PetCO2 may be a rapid and reliable predictor of arterial PaCO2 in respiratory distress.

Sub-optimal chronic obstructive pulmonary disease (COPD) management has been found largely due to patients’ medication non-adherence and incorrect inhaler technique. This study aimed to examine inhaler use technique and medication adherence among Vietnamese COPD patients as well as potential associated factors. A cross-sectional study involving 70 COPD exacerbators was conducted. Inhaler technique and adherence were evaluated by the 10-item and 12-item Test of Adherence to Inhaler (TAI). Data on the history of COPD, home prescription of inhalers and duration of hospitalization were also collected. Generalized linear regression models were used to determine the associated factors with inhaler use and medication adherence. The results showed that the proportion of patients with good inhaler technique was 22.7% for metered-dose inhalers (MDI), 30.4% for dry powder inhalers (DPI) and 31.8% for soft-mist inhalers (SMI). Full exhalation was the most common mistake. The rates of non-compliance patterns were: “ignorant” (77.1%), “sporadic” (58.6%), and “deliberate” (55.7%). Worse dyspnea, greater health condition impairment, and an increased frequency of exacerbations and hospitalizations were found to be associated negatively with correct inhaler use and treatment adherence. Instructions to COPD patients about using inhalers should focus on correct inhaler technique and adherence even when feeling healthy.

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.

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: 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.

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.

Introduction: Sarcopenia is frequently associated with chronic diseases such as chronic obstructive pulmonary disease (COPD). Sarcopenia can be classified as physical frailty where frailty is associated with adverse health outcomes. Sarcopenia was found to be associated with worsening lung function in male COPD patient. Objective was to find out the factors associated with sarcopenia in COPD patients. Materials & Methods: This was cross-sectional observational study was carried out Different Privet Medical in Chandpur and Chandpur Medical College Hospital, Chandpur. Patients diagnosed with COPD according to Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD) guidelines were included in this study. Exclusion criteria were unstable cardiac disease, an exacerbation within the preceding 4 weeks, predominant neurological limitation to walking (eg, significant hemiplegia) or contraindication to bioelectrical impedance analysis (BIA) including an implanted pacemaker or defibrillator. All participants gave written informed consent. EWGSOP criteria were applied to outpatients with stable COPD. Results: In uniavariate analysis, age, moderate COPD, severe COPD, obesity, non-elective admission over the past 12 months, MMRC scale and MAP were significantly associated with sarcopenia. In multivariate analysis, age, moderate COPD, severe COPD, obesity and MMRC scale were significantly associated with sarcopenia. Conclusion: Prevalence of sarcopenia was 26%. Independent factors associated with sarcopenia Age (>70 years) years (adjusted odds ratio (AOR) 4.387. Sarcopenia affects about one-quarter of COPD patients. Age, severity of COPD, MMRC scale, and BMI status were the factors associated with sarcopenia. Medicine Today 2021 Vol.33(1): 50-53
