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.

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.

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.

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.

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.

Obstructive lung disease is a group of disorders comprising Chronic Obstructive Pulmonary Disease (COPD) and asthma. It is one of the most common causes of morbidity and mortality worldwide. COPD is a preventable and treatable disease characterized by persistent respiratory symptoms and airflow limitation, whereas asthma is reversible episodes of recurrent wheezing, cough, breathlessness, and chest tightness. It is sometimes difficult to distinguish COPD from asthma when COPD patients present with significant post-bronchodilator reversibility. Spirometry is the gold standard test to diagnose obstructive airway disease. We carried out a hospital-based cross-sectional study in Nepal Medical College Teaching Hospital from January 2018 to December 2018. One hundred and ninety eight patients who met the inclusion criteria underwent spirometry. Basal and post-bronchodilator FEV1, FVC, FEV1/FVC, and reversibility of FEV1 were measured. The majority of the patients enrolled in the study were males (n=100). The mean age of the patients was 49.3±17.0 years. Most of the patients were above 60 years of age (n=68). Clinical diagnosis of asthma was made in 113 (57%) and COPD in 85 (43%) patients. Post-bronchodilator reversibility was observed in 48 (42%) asthmatic and 19 (22%) COPD patients. Post-bronchodilator reversibility was statistically significant in asthmatic patients (p=0.032). Post-bronchodilator reversibility was observed in COPD patients as well. Therefore, post-bronchodilator reversibility alone may have a limited role in differentiating COPD from bronchial asthma. However, spirometry is mandatory to diagnose a patient with obstructive lung disease.

Abstract Background: Ventilatory inefficiency is known to be a contributor to exercise intolerance in chronic obstructive pulmonary disease (COPD). The intercept of the minute ventilation (V̇E) vs. carbon dioxide output (V̇CO2) plot is a key ventilator inefficiency parameter. However, its relationships with lung hyperinflation (LH) and airflow limitation are not known. This study aimed to evaluate the correlations between the V̇E/V̇CO2 intercept and LH in COPD to determine its utility as an index of functional impairment.Methods: We conducted a retrospective analysis of data from 53 COPD patients and 14 healthy controls performed incremental cardiopulmonary exercise tests and resting pulmonary function. Ventilatory inefficiency was represented by parameters reflecting the V̇E/V̇CO2 nadir and slope (linear region), and intercept of the V̇E/V̇CO2 plot. Their correlations with measures of LH and airflow limitation were evaluated.Results: Compared to the control, the slope (30.58±3.62) and intercept (4.85±1.11) higher in COPDstages1-2, leading to a higher nadir (31.47±4.47) (p<0.05). Despite an even higher intercept in COPDstages3-4 (7.16±1.41), the slope diminished with disease progression (from 30.58±3.62 in COPDstages1-2 to 28.36±4.58 in COPDstages3-4). Compared to the V̇E/V̇CO2 nadir and V̇E/V̇CO2 slope, the intercept was better correlated with peak V̇E/maximal voluntary ventilation (MVV) (r=0.489, p<0.001) and peak V̇O2/watt (r=0.354, p=0.003). The intercept was also significantly correlated with RV/TLC (r=0.588, p<0.001), IC/TLC (r=-0.574, p<0.001), peak VT/TLC (r=-0.585, p<0.001); and airflow limitation forced expiratory volume in 1s (FEV1) % predicted (r=-0.606, p<0.001) and FEV1/forced vital capacity (FVC) (r=-0.629, p<0.001).Conclusion: V̇E/V̇CO2intercept was consistently better correlated with worsening static and dynamic lung hyperinflation and airflow limitation in COPD. V̇E/V̇CO2 intercept emerged as a useful index of ventilatory inefficiency across the severity spectrum of COPD patients.

Nos2 Expression

Competition between nitric oxide synthases (NOSs) and arginases for their common substrate l-arginine could be involved in the regulation of cholinergic airway reactivity and subsequent airway remodeling. The aims of this study were to evaluate the relationships between the expression of this enzymatic balance and the effects of NOS and arginase inhibition on bronchoconstrictive response to acetylcholine of patients without and with early chronic obstructive pulmonary disease (COPD). Twenty-two human bronchi [15 COPD (9 GOLD-0, 6 GOLD-1, -2-A), 7 nonsmokers] were investigated for immunohistochemistry and modulation of acetylcholine-induced airway constriction. Significantly increased expression of NOS2 in immunoblots of bronchial tissue and staining in smooth muscle cells was evidenced in patients with COPD compared with control subjects, whereas no modification of arginase expression was evidenced. Forced expiratory volume in 1 s (FEV1) and NOS2 expression were negatively correlated (ρ = −0.54, P = 0.027). Pharmacological experiments demonstrated that resting tension was elevated in COPD compared with control subjects (2,243 ± 154 vs. 1,574 ± 218 mg, P = 0.03) and was positively correlated with the expression of NOS2 (ρ = 0.61, P = 0.044), whereas constrictor response to acetylcholine was similar [active tension, sensitivity (−logEC10), and reactivity (slope)]. The sole effect of the specific arginase inhibitor Nω-hydroxy-nor-l-arginine (1 μM) was to decrease sensitivity in COPD patients, whereas 1 mM NG-nitro-l-arginine methyl ester unexpectedly decreased resting tension because of a non-cGMP-dependent effect. In conclusion, an upregulation of NOS2 expression in COPD patients is involved in airway tone regulation and functional airflow limitation, whereas increased arginase activity is involved in airway sensitivity.
