О.М. Lomakovsky Influence of statins on indicators of immune inflammation depending on their baseline level in patients with stable coronary heart disease

The aim – to determine the effect of statins upon parameters of immune inflammation, depending on their initial disturbances in patients with stable coronary artery disease.

Material and methods. 54 patients with stable angina pectoris were examined. Venous blood was taken before and after two months of treatment with atorvastatin (20 mg/day) (n=22) or lovastatin (40 mg/day) (n=12) or simvastatin (40 mg/day) (n=20). Immunological parameters such as TNF-α, IL-6, IL-8, IL-10, high-sensitivity CRP, antibodies to low-density oxidized lipoproteins, number of cells with CD40 receptors, functional-metabolic activity of neutrophils and monocytes, and subpopulations of lymphocytes were determined.

Results. Two-month statin administration in equivalent doses led to a moderate decrease in the synthesis of mononuclear cells of proinflammatory cytokines (TNF-α, IL-8) and decrease of functional activity of monocytes in the general group of patients with stable coronary heart disease. The influence of statins on humoral and cellular factors of immune inflammation directly depended on the initial factor level (R=0,32–0,77; Р=0,04–0,00001).

Сonclusions. Statins affect the adaptive and innate links of immunity in patients with stable ischemic heart disease. The effect of statins on humoral (CRP, ТNF-α, IL-6, IL-8, IL-10) and cellular (monocytes, Th, Ts, Th/Ts) factors of immune inflammation in patients with IHD directly depends on the initial level of the factor. The more the initial level of the indicator is changed relative to the control, the greater the normalizing effect of the same dose of statins.
