IL-6 AND IL-10 ACTIVITY IN HYPERTENSIVE MEN WITH MODERATE OR HIGH CARDIOVASCULAR RISK

Abstract

Objective: To assess IL-6, IL-10 activity in hypertensive men with moderate or high cardiovascular risk (CVR). Design and method: 60 hypertensive men with moderate and high CVR were included. Two groups were formed: 1st - 30 hypertensive men with moderate CVR; 2nd - 30 men with high CVR. Control group - 15 men, 45–62 years old, without chronic diseases and hypertension. Anamnesis collection, CVR study, general examination, biochemical blood test, ECG, ECHO were held. IL-6, IL-10 were determined by the enzyme-linked immunosorbent assay method. The Mann-Whitney nonparametric test was used for groups comparison. The statistical significance of different values was determined by using the Pearson's Chi-square test. Correlation analysis was carried out on the basis of Spearman's nonparametric rank correlation. Results: IL-10 activity: moderate risk group - 5.18 [3.74; 7.03] pg/ml, high-risk group - 4.92 [2.96; 6.36] pg/ml, control group - 6.63 [5.90; 9.07] pg/ml. There was a statistically significant IL-10 decrease in the high-risk group in comparison with the control group (p = 0.0175). IL-6 activity: moderate risk group - 1.55 [0.75; 2.68] pg/ml, high-risk group - 1.16 [0.48; 2.41] pg/ml, control group - 1.02 [0.00; 9.83] pg/ml, there were no statistically significant differences in the groups. Correlation analysis revealed a multidirectional relationship between IL-10 and the hypertension duration in two groups: with a high risk a negative correlation was revealed (R = - 0.5, p < 0.01), with a moderate risk a positive correlation was revealed (R = 0.46, p < 0.05). IL-6 positively correlated with the thickness of the carotid artery intima-media complex (R = 0.41, p < 0.05) in men with moderate CVR. Conclusions: IL-10 decrease was revealed in hypertensive men with high CVR as compared to the healthy people. It can be used as an additional criterion for high CVR. The negative IL-10 correlation with the hypertension duration reflects the unfavorable development of hypertension in hypertensive men with high CVR. The detection of high IL-6 values in hypertensive men indicates the risk of endothelial dysfunction.
