The review is devoted to the analysis of literature data related to the role of proteomic studies in the study of atherosclerotic cardiovascular diseases. Diagnosis of patients with atherosclerotic plaques before clinical manifestations is an arduous task. The review presents the results of research on the new proteomic potential biomarkers of coronary heart disease, coronary atherosclerosis, acute coronary syndrome, myocardial infarction, carotid artery atherosclerosis. Also, the analysis of literature data on proteomic studies of the vascular wall was carried out. To assess the involvement of proteins in the pathological process of atherosclerosis, it is important to investigate the specific relationships between proteins in the arteries, expression and concentration of proteins. The development of proteomic technologies has made it possible to analyse the number of proteins associated with the development of the disease. Analysis of the proteomic profile of the vascular wall in atherosclerosis can help to detect possible diagnostically significant protein structures or potential biomarkers of the disease and develop novel approaches to the diagnosis of atherosclerosis and its complications.
The pathogenesis of the development of chronic lung diseases assumes the participation of systemic inflammation factors, as well as hormone-like substances produced by adipose tissue. The aim of this study was to evaluate the associations of certain adipokines/cytokines and chronic bronchitis against the background of abdominal obesity in young people. The study included 1415 people aged 25−44. In total, 115 people were selected by the random numbers method, who were divided into two subgroups: those with chronic bronchitis and abdominal obesity and those with chronic bronchitis without abdominal obesity. A control group of patients with comparable gender and age was also selected. In the group of patients with chronic bronchitis, adiponectin, TNFa and GIP levels were 1.4 times higher. The levels of C-peptide, MCP-1 and PP in the group of chronic bronchitis were 1.3 times higher compared to the control. Adipsin, lipocalin-2, IL-6 and resistin were significantly higher in the group with chronic bronchitis. Glucagon, amylin and ghrelin were 2.2, 2.3 and 3.2 times lower, respectively, in the group of patients with chronic bronchitis. Against the background of abdominal obesity, the probability of having chronic bronchitis increased with an increase in the level of lipocalin-2 and GIP and TNFa.
This work is aimed at studying the relationship of matrix metalloproteinases with calcification of the coronary arteries. The study included 78 people with coronary heart disease (CHD) and 36 without CHD. Blood and samples of coronary arteries obtained as a result of endarterectomy were examined. Serum levels of metalloproteinases (MMP) MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, MMP-10, MMP-12, and MMP-13 were determined by multiplex analysis. In blood vessel samples, MMP-1, MMP-3, MMP-7, and MMP-9 were determined by enzyme immunoassay; MMP-9 expression was evaluated by immunohistochemistry. Patients with CHD had higher serum levels of MMP-1, MMP-7, and MMP-12. Blood levels of MMP-1 and MMP-3 were associated with calcium levels, MMP-9 with osteoprotegerin and osteonectin, MMP-7 and MMP-10 with osteoprotegerin, MMP-12 with osteocalcin, and MMP-13 with osteopontin. Calcified plaques had higher levels of MMP-1 and MMP-9 compared to plaques without calcification. The relative risk of coronary arteries calcification was associated with MMP-9, which is confirmed by the results of immunohistochemistry. The results obtained indicate the participation of some MMPs, and especially MMP-9, in the calcification processes. The study can serve as a basis for the further study of the possibility of using MMP-1, MMP-7 and MMP-12 as potential biomarkers of CHD.
Objective: To identify associations of fatty acids (FAs) with the antioxidant enzymes in the blood of men with coronary atherosclerosis and ischemic heart disease (IHD). Methods: The study included 80 patients: control group—20 men without IHD, the core group—60 men with IHD. The core group was divided into subgroups: subgroup A—with the presence of vulnerable atherosclerotic plaques, subgroup B—with the absence of vulnerable atherosclerotic plaques. We analyzed the levels of FAs, free radicals, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) in the blood. Results. Patients with IHD, compared with the control group: (1) had higher levels of SOD, CAT, myristic, palmitic, palmitoleic, and octadecenoic FAs; (2) had lower levels of GPx, α-linolenic, docosapentaenoic, docosahexaenoic, and arachidonic FAs. In subgroup A there were found: (1) negative associations of SOD—with linoleic, eicosatrienoic, arachidonic, eicosapentaenoic, docosapentaenoic and docosahexaenoic FAs, positive associations—with palmitic acid; (2) positive correlations of CAT level with palmitoleic and stearic acids; (3) negative associations between of GPx and palmitic, palmitoleic, stearic and octadecenoic FAs. Conclusions: Changes in the levels of antioxidant enzymes, and a disbalance of the FAs profile, probably indicate active oxidative processes in the body and may indicate the presence of atherosclerotic changes in the vessels.
Objective The study was dedicated to investigation of some hemostasis and endothelial dysfunction factors association with probability of presence of vulnerable atherosclerotic plaques in coronary arteries in men with atherosclerosis. Results The blood levels of factor VII, factor XII and MCP-1 were higher, and concentration of sVCAM-1 lower in men with vulnerable atherosclerotic plaques in the coronary arteries, compared to men who had stable plaques. Have been revealed correlation links between the blood levels of factor II, factor XII, MCP-1 and the presence of vulnerable atherosclerotic plaques in the coronary arteries. Results of logistic regression analysis showed that the relative risk of present of vulnerable atherosclerotic plaques in the coronary arteries is associated with an elevated blood level of factor XII and MCP-1.
To study the associations of blood proteins with the presence of unstable atherosclerotic plaques in the arteries of patients with coronary atherosclerosis using quantitative proteomics. The studies involved two groups of men with coronary atherosclerosis (group 1 (St) had only stable atherosclerotic plaques; group 2 (Ns) had only unstable atherosclerotic plaques, according to histological analysis of tissue samples); the average age of patients was 57.95 ± 7.22. Protein concentrations in serum samples were determined using the PeptiQuant Plus Proteomics Kit. The identification of protein fractions was carried out by monitoring multiple reactions on a Q-TRAP 6500 mass spectrometer combined with a liquid chromatograph. Mass spectrometric identification revealed in serum samples from patients with unstable atherosclerotic plaques a reduced concentration of proteins in the blood: α-1-acid glycoprotein, α-1-antichymotrypsin, α-1-antitrypsin, ceruloplasmin, hemopexin, haptoglobin, apolipoprotein B-100, apolipoprotein L1, afamin and complement component (C3, C7, C9). Moreover, at the same time a high concentration complements factor H and attractin. The differences were considered significant at p < 0.05. It was found that the instability of atherosclerotic plaques is associated with the concentration of proteins: afamin, attractin, components of the complement system, hemopexin and haptoglobin. The data of our study showed the association of some blood proteins with the instability of atherosclerotic plaques in coronary atherosclerosis. Their potential role in the development of this disease and the possibility of using the studied proteins as biomarkers requires further research.
Background: Our study aimed to assess the relationship between the parameters of the lipid profile, atherogenic index of plasma (AIP), anthropometry influence with the severity of the new coronavirus infection COVID-19 in women. Material and methods. The study design was a cross-sectional study. The research included 138 women aged 29–82 years who had undergone a new coronavirus infection COVID-19 at least two months ago. Participants were divided into three groups by severity of infection: mild (n = 61), moderate (n = 70) and severe (n = 7). Body mass index, waistline and hip circumference, waistline circumference to hip circumference index, total cholesterol, triglycerides, HDL, LDL, AIP were calculated. Statistical processing of the obtained results was carried out using the SPSS software package (version 20.0) using the Mann-Whitney test, univariate logistic regression analysis, Pearson chi-squared test. Results. The levels of HDL-cholesterol were significantly lower in group 3 compared with the level of HDL-cholesterol in women in group 2 (p2-3 = 0.046). BMI was higher in the moderately severe group compared to the mild one (26.32 [23.305; 30.4] versus 28.78 [24.72; 34.77], p1-2 = 0.026). Hip circumference was higher in patients with severe COVID-19 than in patients with mild course (104 [98; 112] versus 114 [109.5; 126], p1-3 = 0.039), AIP was higher in women with severe course compared to women with moderate and mild course (p1-3 = 0.043, p2-3 = 0.04). The results of the logistic regression analysis showed that the moderate course of COVID-19 is associated with BMI (OR = 1.09, 95 % CI 1.019–1.166, p1-2 = 0.012), and the severe course with WC (OR = 1.041, 95 % CI 1.001–1.084, p1-3 = 0.046), AIP value ≥ 0.11 (OR = 13.824, 95 % CI 1.505–126.964, p1-3 = 0.02; OR = 11,579, 95 % CI 1,266–105,219, p2-3 = 0.03) and HDL level < 40 mg/dl (OR = 14,750, 95 % CI 2,317–93,906, p1-3 = 0.004; OR = 8,000, 95 % CI 1,313– 48,538, p1-3 = 0.024). Conclusion. Patients from the group with moderate and severe course of the new coronavirus infection have higher body mass index, hip circumference, AIP, lower HDL values. The chance of a moderate course of COVID-19 is associated with an increased BMI value, and a severe course with WC, AIP ≥ 0.11 and HDL level < 40 mg/dl.
Цель. Изучить некоторые факторы эндотелиальной дисфункции с целью поиска их ассоциаций с факторами свертывания крови, маркерами воспаления и с наличием нестабильных атеросклеротических бляшек в коронарных артериях у мужчин с коронарным атеросклерозом. Материал и методы. У мужчин с коронарным атеросклерозом без острого коронарного синдрома исследовали в крови концентрации факторов эндотелиальной дисфункции (эндотелин 1, моноцитарный хемоаттрактантный протеин 1 типа (MCP-1), адгезивные молекулы sVCAM-1, ассиметричный диметиларгинин, гомоцистеин, ингибитор активатора плазминогена 1 типа), факторов свертывания крови (фактор II, фактор VII, фактор XII, антитромбин III), биомаркеров воспаления (фактор некроза опухоли альфа, интерлейкины (ИЛ-1-бета, ИЛ-6, ИЛ-8), С-реактивный белок). Результаты. Наличие у пациентов в коронарных артериях (КА) нестабильных атеросклеротических бляшек ассоциировалось с повышенным уровнем в крови МСР-1 (выше в 1,9 раз; p<0,05) и сниженной концентрацией sVCAM-1 (ниже в 1,4 раза; p<0,05) по сравнению с мужчинами, у которых, согласно гистологическому заключению при анализе материалов эндартериаэктомии, в коронарных артериях не было нестабильных бляшек. Наибольшее число корреляционных связей выявлено между уровнем в крови MCP-1 и концентрациями фактора VII, антитромбина III, ИЛ-8, С-реактивный белок, ИЛ-1-бета и наличием у мужчин нестабильных атеросклеротических бляшек в КА. Заключение. Полученные результаты показали, что относительный риск наличия в коронарных артериях нестабильных атеросклеротических бляшек связан с повышенным уровнем в крови МСР-1.
