Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality. As such, the disease places a significant burden on health care services. Although the pathogenesis of COPD is complex, progressive airflow limitation and a chronic inflammatory response are two hallmark characteristics of the disease. In addition, systemic manifestations such as peripheral muscle dysfunction have recently received considerable attention in the literature. Pulmonary rehabilitation is an evidence-based multidisciplinary intervention that has been shown to produce clinically relevant outcomes. One important component of rehabilitation is exercise. With the majority of COPD patients presenting with muscle weakness and exercise intolerance, the inclusion of resistance training into a pulmonary rehabilitation programme would seem appropriate. Compared with other exercise/training modalities only a small number of studies have investigated the effects of resistance training in COPD patients. Although further research is required to identify the optimal mode, intensity and frequency, it appears that resistance training may prove to be a valuable intervention for COPD patients enrolled in pulmonary rehabilitation programmes.

Abstract Background Chronic obstructive pulmonary disease (COPD) is characterized by incomplete reversible airflow limitation and chronic inflammatory response lesions. This study mainly explored whether FGFR2 and MGAT5 polymorphisms affected the risk of COPD in the Chinese people. Methods Five variants in FGFR2 and MGAT5 were chosen and genotyped using Agena MassARRAY platform from 315 COPD patients and 314 healthy controls. The correlation of FGFR2 and MGAT5 with COPD susceptibility was evaluated with odds ratio (OR) and 95% confidence interval (CI) via logistic regression. Results We found rs2420915 enhanced the risk of COPD, while rs6430491, rs2593704 reduced the susceptibility of COPD (p < 0.05). Rs2420915 could promote the incidence of COPD in the elderly and nonsmokers. Rs1907240 and rs2257129 also increased the susceptibility to COPD in nonsmokers (p < 0.05). MGAT5-rs2593704 played a protective role in COPD development in different subgroups (age ≤ 70, male, smokers, and individuals with BMI ≤ 24 kg/m2). Meanwhile, rs6430491 was linked with a lower risk of COPD in nonsmoking and BMI ≤ 24 kg/m2 subgroups. Conclusions We concluded that FGFR2 and MGAT5 genetic polymorphisms are correlated with the risk of COPD in the Chinese people. These data underscored the important role of FGFR2 and MGAT5 gene in the occurrence of COPD and provided new biomarkers for COPD treatment. Trial registration: NA.

Background/Aim. Peripheral muscle weakness and nutritional disorders, firstly loss of body weight, are common findings in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to analyse the impact of pulmonary function parameters, nutritional status and state of peripheral skeletal muscles on exercise tolerance and development of dyspnea in COPD patients. Methods. Thirty COPD patients in stable state of disease were analyzed. Standard pulmonary function tests, including spirometry, body pletysmography, and measurements of diffusion capacity were performed. The 6-minute walking distance test (6MWD) was done in order to assess exercise tolerance. Level of dyspnea was measured with Borg scale. In all patients midthigh muscle cross-sectional area (MTCSA) was measured by computerized tomography scan. Nutritional status of patients was estimated according to body mass index (BMI). Results. Statistically significant correlations were found between parameters of pulmonary function and exercise tolerance. Level of airflow limitation and lung hyperinflation had significant impact on development of dyspnea at rest and especially after exercise. Significant positive correlation was found between MTCSA and exercise tolerance. Patients with more severe airflow limitation, lung hyperinflation and reduced diffusion capacity had significantly lower MTCSA. Conclusion. Exercise tolerance in COPD patients depends on severity of bronchoobstruction, lung hyperinflation and MTCSA. Severity of bronchoobstruction and lung hyperinflation have significant impact on dyspnea level.

Basic Activity

Chronic obstructive pulmonary disease (COPD) is defined as persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases. It has been suggested that emotional disturbances such as depression and anxiety are common among patients with COPD. This review aims to highlight the presence of depression and associated risk factors among patients suffering from COPD in Asia. Fifty-eight observational studies were retrieved through data sources like PubMed, Medical subject heading (MeSH) search and Google scholar. After thorough screening total thirteen studies were identified and included in this review. Based on the results of these studies, the south and west Asian countries had higher proportion of depression. However, risk factor results were mixed which includes severity of obstruction/global initiative for obstructive lung disease (GOLD) criteria, Stage 2 COPD, teetotallers, smoking, alcohol consumption, body mass index, airflow obstruction, dyspnoea, and exercise (BODE) index, urban residence, female gender, education level, dyspnoea, low income, poor Quality of life (QOL) scores, age, poor self-reported health, basic activity of daily living (BADL) disability. Further superior research studies with larger sample size are required on Asian population. All in all, it is recommended that early diagnosis and treatment of depression should be included as a part of management in COPD as it can help to minimize the risk of morbidity and mortality in the patients.

Chronic obstructive pulmonary disease (COPD) is a respiratory disease associated with airways inflammation and lung parenchyma fibrosis. The primary goals of COPD treatment are to re-duce symptoms and risk of exacerbations, therefore pulmonary rehabilitation is considered the key component of managing COPD patients. Oxidative airway damage, inflammation and re-duction of endogenous antioxidant enzymes are known to play a crucial role in the pathogenesis of COPD. Natural antioxidants have also recently been considered as they play an important role in metabolism, DNA repair and fighting the effects of oxidative stress. In this paper we evaluated the response of 105 elderly COPD patients to pulmonary rehabilitation (PR), based on high or low vegetable consumption, by analyzing clinical parameters and biological measure-ments at baseline and after completion of the three weeks PR. We found that high vegetable in-take in normal diet, without any specific intervention, can increase the probability to success-fully respond to rehabilitation (65.4% of responders ate vegetables daily vs. 40.0% of Non-Responders, p=0.033). Three weeks of pulmonary rehabilitation are probably too short to reveal a reduction of the oxidative stress and DNA damage, but are enough to show an im-provement in the patient's inflammatory state.

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.

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.

Peripheral muscle dysfunction, associated with reductions in fiber cross-sectional area (CSA) and in type I fibers, is a key outcome in chronic obstructive pulmonary disease (COPD). However, COPD peripheral muscle function and structure show great heterogeneity, overlapping those in sedentary healthy subjects (SHS). While discrepancies in the link between muscle structure and phenotype remain unexplained, we tested whether the fiber CSA and the type I fiber reductions were the attributes of different phenotypes of the disease, using unsupervised clustering method and post hoc validation. Principal component analysis performed on functional and histomorphological parameters in 64 COPD patients {forced expiratory volume in 1 s (FEV1) = 42.0 [30.0–58.5]% predicted} and 27 SHS (FEV1 = 105.0 [95.0–114.0]% predicted) revealed two COPD clusters with distinct peripheral muscle dysfunctions. These two clusters had different type I fiber proportion (26.0 ± 14.0% vs. 39.8 ± 12.6%; P < 0.05), and fiber CSA (3,731 ± 1,233 vs. 5,657 ± 1,098 μm2; P < 0.05). The “atrophic” cluster showed an increase in muscle protein carbonylation (131.5 [83.6–200.3] vs. 83.0 [68.3–105.1]; P < 0.05). Then, COPD patients underwent pulmonary rehabilitation. If the higher risk of exacerbations in the “atrophic” cluster did not reach statistical significance after adjustment for FEV1 (hazard ratio: 2.43; P = 0.11, n = 54), the improvement of VO2sl after training was greater than in the nonatrophic cluster (+24 ± 16% vs. +6 ± 13%; P < 0.01). Last, their age was similar (60.4 ± 8.8 vs. 60.8 ± 9.0 yr; P = 0.87), suggesting a different time course of the disease. We identified and validated two phenotypes of COPD patients showing different muscle histomorphology and level of oxidative stress. Thus our study demonstrates that the muscle heterogeneity is the translation of different phenotypes of the disease.

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.

Backgrounds: Type 2 diabetes mellitus (DM) is a common comorbidity of COPD. COPD may be considered as a risk factor for new onset type 2 DM via multiple pathophysiological alterations such as systemic inflammation, smoking, oxidative stress, obesity and inhaled corticosteroid use. Exact prevalence of DM in COPD patients in Indonesia still unclear. Co-morbid conditions like DM have great impact on the outcome of COPD in the form of severity, morbidity and mortality. Methods: A cross sectional study was done in Asthma-COPD clinic Persahabatan Hospital from February to March 2017 to screen COPD patients for DM. Sixty-four subjects were recruited. Interview, physical examination and laboratory testing were performed in all subjects. Results: A total of 64 patients with COPD (Males=60, Female=4) with mean age 65±8.7 were screened for DM. Patients with known history of DM were 12 subjects (18.8%) and were enrolled as known DM cases. Remaining 52 subjects (81.3%) whose DM status was unclear were screened by random or fasting blood sugar and HbA1c. Two subjects (3.1%) were considered as newly diagnosed DM cases. Prevalence of DM in present study was 21.9%. Number of patients with pre-diabetes was 16 subjects (25%). There was no significant relationship between gender, age, smoking, nutritional status, airflow limitation and inhaled corticosteroid use in occurrence of DM among COPD patients. Conclusions: Prevalence of DM in COPD patients in the present study is 21.9%. It is important to screen all COPD patients for DM routinely. (J Respir Indo. 2020; 40(1): 48-57)
