Aim. To reveal the systemic manifestations of chronic obstructive pulmonary disease and to match them with respiratory function parameters and extrapulmonary manifestations as the disease progresses. Methods. 160 patients were examined (128 patients with different stages of chronic obstructive pulmonary disease - the study group, and 32 healthy volunteers - the control group). Clinical examination, serum cytokine concentration measurement, lung function tests, airway resistance and lung volumes evaluation, assessment of hemodynamic parameters, bone mineral density assessment were conducted. Correlations between listed parameters were estimated. Results. It was found that the activation of systemic inflammation occurs at the early stages of the disease with the further increase as it progresses, as was shown by the increase of interleukin-6, interleukin-8, tumor necrosis factor alpha (TNF-α), C-reactive protein levels in the study group compared to the control. The relation between spirometry parameters and inflammatory markers confirmed the role of systemic inflammation in chronic obstructive pulmonary disease progression and cardiovascular complications development. A correlation between the C-reactive protein level and forced expiratory volume at 1st second (FEV 1), as well as between TNF-α level and FEV 1, TNF-α level and lung vital capacity was found. The study also confirmed the role of lung hyperinflation in pulmonary hypertension and chronic cor pulmonale occurrence and progression: mean pulmonary arterial pressure correlated with residual volume to total lung capacity ratio in patients with FEV 1 50% and in patients with FEV 1 50%. Significant correlations between lung function and parameters of pulmonary hemodynamics (FEV 1 with right ventricular end-diastolic dimension) were revealed. Correlations between femoral neck bone mineral density and residual lung volume and diffusing lung capacity confirmed the role of progressive emphysema and hypoxia in the pathogenesis of osteoporosis in patients with chronic obstructive pulmonary disease. Conclusion. Correlations between the severity of airway obstruction and systemic manifestations of chronic obstructive pulmonary disease were revealed.

Necrosis Factor

Interleukin (IL)-1α, IL-1β, IL-6, IL-8 and tumor necrosis factor (TNF)α contribute to inflammation in chronic obstructive pulmonary disease (COPD). We wanted to investigate their interrelations and association with disease severity, as well as to combine them with other inflammation-associated biomarkers and evaluate their predictive value and potential in identifying various patterns of systemic inflammation. One hundred and nine patients with stable COPD and 95 age- and sex-matched controls were enrolled in the study. Cytokines’ concentrations were determined in plasma samples by antibody-based multiplex immunosorbent assay kits. Investigated cytokines were increased in COPD patients but were not associated with disease or symptoms severity. IL-1β, IL-6 and TNFα showed the best discriminative values regarding ongoing inflammation in COPD. Inflammatory patterns were observed in COPD patients when cytokines, C-reactive protein (CRP), fibrinogen (Fbg), extracellular adenosine triphosphate (eATP), extracellular heat shock protein 70 (eHsp70) and clinical data were included in cluster analysis. IL-1β, eATP and eHsp70 combined correctly classified 91% of cases. Therefore, due to the heterogeneity of COPD, its assessment could be improved by combination of biomarkers. Models including IL-1β, eATP and eHsp70 might identify COPD patients, while IL-1β, IL-6 and TNFα combined with CRP, Fbg, eATP and eHsp70 might be informative regarding various COPD clinical subgroups.

Background: Tumor necrosis factor alpha (TNF α) is the most widely studied cytokine of TNF super family. TNF α plays a significant role in many inflammatory diseases affecting the lung, such as chronic bronchitis (CB), chronic obstructive pulmonary disease (COPD), asthma, acute lung injury (ALI) and acute respiratory distress syndrome. Elevated levels of TNF-alpha are seen in COPD patients. An increased level of TNF-α has been found in induced sputum or lung biopsy of COPD patients. 14-16 This study includes correlation of level of TNF α with severity and characterization of individuals with COPD. There are only limited numbers of studies being conducted regarding this topic in the world, including India. Objectives of present study were to measure the TNF-α level in patients with chronic obstructive pulmonary disease and to correlate TNF α level with severity of chronic obstructive pulmonary disease.Methods: The study was conducted on one hundred and eight (108) patient’s COPD patients attending the Pulmonary medicine department of Sri Manakula Vinayagar Medical College and Hospital Puducherry, who are aged above forty years, with a duration of 18 months, starting from the date of getting approval from the Ethics Committee. The subjects were analysed on their TLC, DLC was done to rule out any co-existing infections. Spirometry was done to confirm the diagnosis of COPD. Blood was taken from the confirmed COPD patients after getting their approval, for the estimation of serum TNF α level.Results: The Serum TNF alpha levels increases according to the COPD severity. The mean serum TNF alpha level in patients with mild obstruction, moderate obstruction, severe and very severe obstruction were 9.91+2.9, 21.25+4.8, 32.4+8.2 and 39.2+3.1pg/dl respectively. Mean TNF alpha value was 26.7pg/dl. The values of TNF α increases with the stages of COPD which is statistically significant with p value of 0.0001.Conclusions: The present study showed that serum TNF alpha level correlates with severity of airway obstruction in spirometry among the COPD patients. It also correlates with the disease severity as per the different stages of COPD patients (GOLD COPD staging 2016). Thus, serum TNF alpha is a useful marker to monitor the disease severity in addition to spirometric parameters like FVC, FEV1 and FEV1/FVC. However, further studies are needed with larger sample size.

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.
