Introduction. The prevalence of COPD worldwide is about 7.6 %, and it is one of the main causes of morbidity and mortality in today society. Today, much information has been obtained about the pathogenetic mechanisms of COPD development. However, more and more studies have recently shown that COPD patients have an increase in proinflammatory mediators that contribute to the development of systemic subclinical inflammation; this is due to the involvement of inflammatory cells from the bloodstream in the process, and the development of a systemic inflammatory response. An urgent medical and social problem of our time is the development of pulmonary hypertension in patients with COPD. The processes of inflammation and remodeling of the vascular wall are inseparable; they complement each other, leading to the formation of a clinical picture of pulmonary hypertension.
The aim of the study. To determine the levels of markers of systemic inflammatory response among patients with pulmonary hypertension on the background of COPD.
Materials and methods. The results of the study are based on data from a comprehensive survey of 170 patients aged 40 to 65 years with COPD, 123 of which had pulmonary hypertension and 47 ones had no PH.
Obtained results. The level of hs-CRP in the group of PH patients with COPD was 10.46 [6.24; 15.30] mg/l and was significantly higher, both against the value of 7.30 [6.22; 9.18] mg/l in the group of COPD patients without PH (p < 0.05), and in comparison with the group of healthy individuals, where this indicator was 1.08 [0.96; 1.41] mg/l, (p < 0.05). The increase in IL-6 levels was significantly higher by 57% in the group of PH patients with COPD compared to the value of 5.67 [4.44; 6.98] PG/ml, (p < 0.05) in the group of COPD without PH and amounted to 8.90 [7.76; 9.93] PG/ml, and a 7.4-fold increase in the value of 1.20 [0.95; 1.57] PG/ml in the group of healthy individuals, (p < 0.05). The median level of IL-10 was significantly higher in the group of healthy individuals by 11.2 % and 10 % compared to the groups of patients with PH on the background of COPD and COPD without PH, respectively, and was 5.35 [4.97; 6.86] PG/ml, (p < 0.05). In the groups of patients with PH on the background of COPD and COPD without PH, there was a significant increase in this indicator by 8.8 and 6 times compared to the level of 0.21 [0.20; 0.25] in the group of healthy individuals, (p < 0.05). Comparing subgroups of patients depending on the type of COPD exacerbation, the level of hs-CRP, IL-6 and the ratio of IL-6/IL-10 levels were significantly higher in the subgroup with infectious type of exacerbation compared to the subgroup of non-infectious type of COPD exacerbation, (p < 0.05).
