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.

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.

Significant Factors

Chronic obstructive pulmonary disease (COPD) is a common preventable and treatable disease, characterized by 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. The major risk factor of COPD, which has been proven in many studies, is the exposure to cigarette smoke. However, it is 15–20% of all smokers who develop COPD. This is why we should recognize the pathobiology of COPD as involving a complex interaction between several factors, including genetic vulnerability. Oxidant-antioxidant imbalance is recognized as one of the significant factors in COPD pathogenesis. Numerous exogenous and endogenous sources of ROS are present in pathobiology of COPD. One of endogenous sources of ROS is mitochondria. Although leakage of electrons from electron transport chain and forming of ROS are the effect of physiological functioning of mitochondria, there are various intra- and extracellular factors which may increase this amount and significantly contribute to oxidative-antioxidative imbalance. With the coexistence with impaired antioxidant defence, all these issues lead to oxidative and carbonyl stress. Both of these states play a significant role in pathobiology of COPD and may account for development of major comorbidities of this disease.

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.

Disease Epidemiology

Chronic obstructive pulmonary disease (COPD), the frequently fatal pathology of the respiratory tract, accounts for half a billion cases globally. COPD manifests via chronic inflammatory response to irritants, frequently to tobacco smoke. The progression of COPD from early onset to advanced disease leads to the loss of the alveolar wall, pulmonary hypertension, and fibrosis of the respiratory epithelium. Here, we focus on the epidemiology, progression, and biomarkers of COPD with a particular connection to lung cancer. Dissecting the cellular and molecular players in the progression of the disease, we aim to shed light on the role of smoking, which is responsible for the disease, or at least for the more severe symptoms and worse patient outcomes. We summarize the inflammatory conditions, as well as the role of EMT and fibroblasts in establishing a cancer-prone microenvironment, i.e., the soil for ‘COPD-derived’ lung cancer. We highlight that the major health problem of COPD can be alleviated via smoking cessation, early diagnosis, and abandonment of the usage of biomass fuels on a global basis.

AbstractCachexia and muscle wasting is a frequent but partly reversible complication in patients with chronic obstructive pulmonary disease (COPD), and affects the disease progression and prognosis. Weight loss in COPD is a consequence of increased energy requirements unbalanced by dietary intake. Nutritional supplement therapy has been shown to be effective for maintaining and improving the muscle strength and exercise tolerance in poorly nourished COPD patients, thereby decreasing morbidity and mortality. This mini review discusses the role of nutritional supplement therapy in the treatment of COPD.

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.

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.

Blood Eosinophils

Blood eosinophils measurement, as proxy for tissue eosinophils, has become an important biomarker for exacerbation risk and response to inhaled corticosteroids (ICS) in Chronic Obstructive Pulmonary Disease (COPD). Its use to determine the pharmacological approach is recommended in the latest COPD guidelines. The potential role of blood eosinophils is mainly based on data derived from post-hoc and retrospective analyses that showed an association between increased blood eosinophils and risk of exacerbations, as well as mitigation of this risk with ICS. Yet other publications, including studies in real life COPD, do not confirm these assumptions. Moreover, anti-eosinophil therapy targeting interleukin (IL)-5 failed to reduce exacerbations in COPD patients with high blood eosinophils, which casts significant doubts on the role of eosinophils in COPD. Furthermore, a reduction of eosinophils might be harmful since COPD patients with relatively high eosinophils have better pulmonary function, better life quality, less infections and longer survival. These effects are probably linked to the role of eosinophils in the immune response against pathogens. In conclusion, in COPD, high blood eosinophils are widely used as a biomarker for exacerbation risk and response to ICS. However, much is yet to be learned about the reasons for the high eosinophil counts, their variations and their controversial effects on the fate of COPD patients.
