Abstract

Pulmonary arterial hypertension (PAH) is a complex disorder characterized by increased pressure in the pulmonary arteries, leading to right heart failure. While the exact mechanisms underlying PAH are not fully understood, cytokines have been implicated in the pathogenesis of the disease. Cytokines play a crucial role in regulating immune responses and inflammation. These small proteins also play a key role in shaping the immunophenotype, which refers to the specific characteristics and functional properties of immune cells, which can have a significant impact on the development of PAH. The aim of this study was to determine the immunophenotype and the concentration of selected cytokines, IL-2, IL-4, IL-6, IL-10, and IFN-gamma, in patients diagnosed with PAH (with particular emphasis on subtypes) in relation to healthy volunteers. Based on the obtained results, we can conclude that in patients with PAH, the functioning of the immune system is deregulated as a result of a decrease in the percentage of selected subpopulations of immune cells in peripheral blood and changes in the concentration of tested cytokines in relation to healthy volunteers. In addition, a detailed analysis showed that there are statistically significant differences between the PAH subtypes and the tested immunological parameters. This may indicate a significant role of the immune system in the pathogenesis of PAH.

摘要

肺动脉高压(PAH)是一种复杂的疾病,其特征是肺动脉内压力升高,导致右心衰竭。虽然 PAH 的具体发病机制尚不完全清楚,但细胞因子已被认为与该疾病的发病机制有关。细胞因子在调节免疫反应和炎症中起着至关重要的作用。这些小分子蛋白在塑造免疫表型方面也起着关键作用,免疫表型是指免疫细胞的特定特征和功能特性,它对 PAH 的发展有重大影响。本研究的目的是确定诊断为 PAH(特别强调亚型)的患者与健康志愿者相比,其免疫表型和选定细胞因子(IL-2、IL-4、IL-6、IL-10 和 IFN-γ)的浓度。根据获得的结果,我们可以得出结论,在 PAH 患者中,由于外周血中选定免疫细胞亚群的百分比下降以及与健康志愿者相比测试细胞因子的浓度发生变化,免疫系统的功能失调。此外,详细分析表明,PAH 亚型与测试免疫参数之间存在统计学上的显著差异。这可能表明免疫系统在 PAH 的发病机制中起着重要作用。
