Background: Chronic obstructive pulmonary disease (COPD) represents an important public health challenge. It is a major cause of chronic morbidity and mortality throughout the world. Arterial hypertension (AH) is considered one of the principal COPD-associated comorbidities. Objective: The study was aimed to assess the role of angiotensinogen (AGT) gene polymorphism in occurrence of AH in patients with COPD. Methods: The study was conducted among 96 patients of them, Group 1 (25 individuals with COPD), Group 2 (23 individuals with AH), Group 3 (28 individuals with COPD and AH). The control group consisted of the 20 healthy subjects. I/D genotypes of AGT were determined by polymerase chain reaction amplification. Plasma AGT activity was determined photometrically by a commercially available kit. Results: The results of the study have not demonstrated any significant impact of alleles of AGT genes on occurrence of such disease as COPD, AH and combinations thereof. However, analysis of odds ratio has demonstrated the presence of a trend towards a protective role of the M allele of the AGT gene concerning occurrence of COPD, AH and their combinations (OR=0.90, OR=0.71 and OR=0.56, respectively). At the same time, the presence of the T allele of the AGT gene may increase the risk for occurrence of the above mentioned disease (OR=1.11, OR=1.4 and OR=1.79, respectively). Conclusion: The study suggests that the presence of Т allele of the AGT gene at position 235 of the peptide chain both in homozygous and heterozygous state may increase the risk for AH in patients with COPD.

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.

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.
