Nitric Oxide System

ABSTRACT The clinical picture and long-term prognosis of chronic obstructive pulmonary disease (COPD) largely depend on comorbid conditions, thereby prompting a relevant search for predictive and preventive methods in the pathogenesis of the disease. Cardiovascular diseases are highly prevalent among patients with COPD. Cardiovascular risks in patients with COPD are associated with changes in the activity of vasoactive mediators, with nitric oxide (NO) being the most important. The important role of nitric oxide in the body prompts it being studied as a biomarker of many diseases; however, its short half-life and rapid clearance prevent its direct assessment in the blood. In the body, nitric oxide is formed from L-arginine with the help of enzymes of NO-synthase group. NO oxide synthesis depends on the concentration of L-arginine, arginase and asymmetric dimethylarginine (inhibitory effect on NO-synthase). The presented literature review highlights modern views on the importance of nitric oxide and regulators of its synthesis in the pathogenesis of chronic obstructive pulmonary disease. It also indicates their role in the formation of comorbid conditions, and highlights processes of NO formation in the body. CONCLUSION: The components of the nitric oxide system (nitric oxide metabolites, L-arginine, arginase, dimethylarginine dimethylaminohydrolase, asymmetric and symmetric dimethylarginine) can be considered as potential biomarkers of COPD, especially in conditions of cardiovascular comorbidity. Further studies on the nitric oxide system are recommended for assessing the prognosis of the course of diseases and the effectiveness of the current therapy.

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.

The aim: To evaluate the effect of overweight on the quality of life of chronic obstructive pulmonary disease (COPD) patients GOLD III. Materials and methods: 65 patients with chronic obstructive pulmonary disease (COPD GOLD III) were examined in different phases of pathological process. The pulmonary function (PF) test was performed by means of “SPIROKOM” device (Ukraine). The degree of overweight was determined by calculating the body mass index (BMI) using the formula І = m/h² (m – body mass in kilograms, h – height, square of the height in meters (kg/m²). Patients’ quality of life was evaluated with the help of standardized St.George’s Respiratory Questionnaire (SGRQ). Results: The study revealed changes in the PF indices and the decrease in quality of life in overweight patients, especially in case of destabilization of the pathological process. Conclusions: The obtained results show that overweight is the underlying condition for more severe course of the pathology and requires further study of its impact on the health and quality of life of patients in order to improve the effectiveness of treatment.

Active Forms Of Oxygen

Chronic obstructive pulmonary disease (COPD) is a common disease involving the pathological process, of bronchopulmonary and cardiovascular systems. This is a complex disease in which inflammation plays a leading role in the formation of the whole complex of pathological changes. COPD accompanies local deficit of antiproteases, excessive formation of active forms of oxygen, inducing uncontrolled lipid peroxidation and oxidative stress. An increase in the level of proinflammatory cytokines, such as IL-6, IL-8, TNF-α, is particularly significant in the combination of chronic obstructive disease with metabolic syndrome. Determination of a specific phenotype of COPD, and the degree of disruption of protective and adaptive systems in these forms of the disease course allows optimizing the treatment regimens for patients. The purpose of this work was to identify additional biochemical and biophysical markers of phenotyping and monitoring of therapy in patients with COPD of different phenotype and severity level in the acute stage on the basis of studying the main indicators of the system of antioxidant protection of blood and some cytokines. Significant differences in antioxidant system (AOS) indices in patients with COPD of different phenotype and severity were determined. The established differences in the activity of erythrocyte enzymes and the overall antioxidant activity of blood plasma can serve as an important additional link for the phenotyping of COPD. Complex treatment with the use of anticoagulants, normalizing the rheological properties of blood and mucolytics with pronounced antioxidant properties, reduces the level of prooxidant load on the body due to correction of metabolic processes and has the most pronounced effect on AOS blood parameters and cytokine profile.

The second part of the review examines in detail the questions of diagnostics and peculiarities of the metabolic syndrome manifestations, which presents the link between most comorbid conditions at patients with chronic obstructive pulmonary disease. The metabolic syndrome is based on the insulin resistance and compensatory hyperinsulinemia, caused by both chronic low‑intensity inflammation and increased adipose tissue, often against the background of aggravated heredity at diabetes mellitus. The authors elucidate aspects of the effects of obesity, cachexia and some endocrine disorders on the disease course. The deficiency of researches on endocrine status, especially thyroid function and related metabolic disorders was emphasized. Possible pathogenetic mechanisms of osteoporosis development in this contingent of patients are considered. The need for further research of the pathogenetic role of vitamin D is discussed. Data on the role of the functional state of kidneys in the development of metabolic disorders in an organism have been presented, though kidney pathology in patients with chronic obstructive pulmonary disease is not currently considered as a comorbid condition. The contradictory literature data on the development of anemia in these patients were analysed. The authors presented data on the development of oncological processes as a systemic manifestation at COPD and performed analysis of common and mutually aggravating mechanisms of the development of these pathological conditions. Attention has been paid to the relationship between gastroesophageal reflux disease, bronchiectasis and obstructive sleep apnea with chronic obstructive pulmonary disease. The prospects of modern genetic research in chronic obstructive pulmonary disease and comorbid conditions have been determined.
