The Impact

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease that combines various clinical manifestations and pathophysiological mechanisms. It underlies the separation of patients with COPD by phenotypes, endotypes and a personalized therapy of this disease. The implementation of this approach is possible only with the use of appropriate biomarkers. One of the most important biomarkers of COPD is eosinophilia of blood and/or sputum, which is considered as a predictor of frequent exacerbations and the effectiveness of inhaled glucocorticosteroids in patients with COPD. The literature discusses the impact of eosinophilic inflammation on the prognosis, clinical and functional parameters in COPD, and the role of the targeted therapy in the treatment of eosinophilic COPD.

The Impact

The main objectives of chronic obstructive pulmonary disease (COPD) therapy are to reduce the severity of symptoms and the risk of exacerbations. The article discusses the role of local and systemic inflammation in the pathogenesis of COPD as well as various mechanisms of pharmacological influence on it. Approaches to prescribing basic therapy for patients with COPD, recommended by various national and global guidelines (clinical recommendations of the Russian respiratory society, criteria of the Global Initiative for Chronic Obstructive Lung Disease (GOLD), guidelines of the National Institute for Health and Clinical Excellence (NICE)), as well as recommendations on the therapy frequency review are considered. Currently, so-called triple combinations – fixed combinations of double bronchodilators with inhaled glucocorticosteroids – are being developed and registered in the world, and their place and significance in the treatment of COPD raise many discussions. The paper discusses the role of fixed triple combinations in reducing the incidence of COPD exacerbations, the impact on functional and patient-reported outcomes, and provides recommendations for the use of triple combinations in patients with COPD, taking into account the benefit/risk ratio.

The Impact

AbstractChronic obstructive pulmonary disease is a progressive lung disease characterized by chronic obstruction of the lung airflow that interferes with normal bleeding and is not fully reversible. Chronic smoking is the most common risk factor for COPD causing severe cough, wheezing, labored breathing and reduced functionality. COPD not only exerts pulmonary symptoms but also has a spill over the extra pulmonary effects. Owing to the impact of the disease, it may lead to conditions like osteoporosis, cardiovascular complications as well as to psychological effects such as depression and anxiety. Such comorbidities are hidden and are not effectively treated. Depression, one of the most common hidden comorbidities is known to be present but never diagnosed. Various scales like HAM-D and Bode Index can be used to diagnose the extent of depression. Our review mainly focuses on the various studies conducted worldwide and comparing the results of the same. Based on the worldwide analysis, depression is known to affect a COPD patient at later stages and requires immediate diagnosis and appropriate treatment.

Steroid Response

A kilégzett levegőben mérhető nitrogén-monoxid a legszélesebb körben vizsgált légúti biomarker. A stabil állapotú krónikus obstruktív tüdőbetegségben a kilégzett nitrogén-monoxid-szint hasonló vagy csak kismértékben emelkedett az egészségesekhez képest. Mivel a nitrogén-monoxid-szint szoros összefüggést mutat a légúti eosinophilia mértékével, és mivel az eosinophil típusú légúti gyulladás szteroidokra érzékenyebb, az emelkedett nitrogén-monoxid-szinttel rendelkező betegek jobb válaszkészséget mutatnak az inhalációs vagy szisztémás kortikoszteroidkezelésre. A krónikus obstruktív tüdőbetegség akut exacerbatiója során a kilégzett nitrogén-monoxid szintje megemelkedik, majd ennek kezelése után csökken. Mivel a nitrogén-monoxid-szint és a kezelés során elért légzésfunkciós javulás szoros korrelációt mutat egymással, a nitrogén-monoxid-méréssel a terápiás válasz megjósolható. Összefoglalva: a nitrogén-monoxid-méréssel a krónikus obstruktív tüdőbetegségben szenvedő betegek olyan alcsoportját lehet elkülöníteni, amelynek szteroidérzékenysége nagyobb. Orv.

Current Paradigm

Despite all achievements of the modern medicine, the problem of chronic obstructive pulmonary disease (COPD) does not lose its relevance. The current paradigm suggests a key role of macrophages in inflammation in COPD. Macrophages are known to be heterogeneous in their functions. This heterogeneity is determined by their immunometabolic profile and also by peculiarities of lipid homeostasis of cells. Aim. To analyze the role of the ABCA1 transporter, a member of the ABC A subfamily, in the pathogenesis of COPD. The expression of ABCA1 in lung tissues is on the second place after the liver, which shows the important role of the carrier and of lipid homeostasis in the function of lungs. Analysis of the literature shows that participation of the transporter in inflammation consists in regulation of the content of cholesterol in the lipid rafts of the membranes, in phagocytosis and apoptosis. Conclusion. Through regulation of the process of reverse transport of cholesterol in macrophages of lungs, ABCA1 can change their inflammatory response, which makes a significant contribution to the pathogenesis of COPD.

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.

The Impact

Objectives To understand how people with Chronic Obstructive Pulmonary Disease (COPD) disavow their support needs and the impact on care. Methods Two stage mixed-method design. Stage 1 involved sub-analyses of data from a mixed-method population-based longitudinal study exploring the needs of patients with advanced COPD. Using adapted criteria from mental health research, we identified 21 patients who disavowed their needs from the 235 patient cohort. Qualitative interview transcripts and self-report measures were analysed to compare these patients with the remaining cohort. In stage 2 focus groups (n = 2) with primary healthcare practitioners (n = 9) explored the implications of Stage 1 findings. Results Patients who disavowed their support needs described non-compliance with symptom management and avoidance of future care planning (qualitative data). Analysis of self-report measures of mental and physical health found this group reported fewer needs than the remaining sample yet wanted more GP contact. The link between risk factors and healthcare professional involvement present in the rest of the sample was missing for these patients. Focus group data suggested practitioners found these patients challenging. Discussion This study identified patients with COPD who disavow their support needs, but who also desire more GP contact. GPs report finding these patients challenging to engage.

Supplement Therapy

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.
