Abstract

Background: The role of inflammation in the development of atherosclerosis and its complications has been recently documented. Pro-inflammatory cytokines are among many postulated factors. It is possible that the imbalance between protective cytokines and cytokines affecting endothelial function is one of the underlying mechanisms of myocardial ischaemia.
Aim: To examine the effects of simvastatin on IL-2 and TNFα levels in patients with hypercholesterolemia.
Methods: The study group consisted of 64 males (age 20-65 years) with hypercholesterolemia. The control group was composed of 10 healthy male volunteers (age 25-40 years) with normal lipid profile. Total cholesterol, LDL-cholesterol, IL-2 and TNFα were measured in both groups at baseline, after three months of dietary treatment, and after a further three months of simvastatin therapy.
Results: Simvastatin caused a significant decrease in the total and LDL-cholesterol levels compared both with baseline measurements (p=0.0001) and after dietary treatment (p=0.0001). Moreover, simvastatin significantly reduced the IL-2 plasma concentration (p=0.0003). There were no significant differences between IL-2 levels before and following dietary treatment. The TNFα serum concentration significantly decreased following the implementation of diet (p=0.0001). Subsequent simvastatin therapy caused further decrease in the TNFα serum concentration but this difference did not achieve statistical significance.
Conclusions: A hypolipemic diet significantly decreases TNFα serum concentration without affecting the IL-2 level. The subsequent simvastatin therapy significantly reduces IL-2 but not TNFα when compared with the post-diet values.
