| Popis: | Background. Chronic obstructive pulmonary disease is a socially significant disease affecting patient’s quality of life. Assessment of endogenous intoxication in patients with chronic obstructive pulmonary disease will allow to understand pathogenetic features of different phenotypes of this disease, which can be taken into account when predicting its course.The aim of the study. To determine the prognostic value of levels of mediumand low-molecular-weight substances and oligopeptides in patients with chronic obstructive pulmonary disease.Materials and methods. One hundred and four patients with chronic obstructive pulmonary disease (COPD) and 110 somatically healthy individuals were examined. Molecular weight medium and low molecular weight substances (LMWSM) and oligopeptides (OP) were determined in blood plasma, erythrocytes and urine. Based on these indicators mathematically calculated indices of endogenous intoxication and coefficient of elimination were defined. Statistical processing of the data was performed using the SPSS 26.0 software package (IBM Corp., USA).Results. In all biological fluids, the levels of average molecules and calculated indices in the COPD patients’ group were statistically significantly different from those in the control group. The indices characterizing endotoxin accumulation were statistically significantly higher, while those characterizing toxin elimination were lower. The level of endotoxemia was correlated with the frequency of exacerbations, clinical manifestations severity, quality of life, COPD group and phenotype.Conclusions. Frequent exacerbations, groups C and D, bronchitic and mixed COPD phenotypes are characterized by more severe endotoxicosis manifested by high levels of LMWSM, OP and calculated indices. |
