Abstract

OBJECTIVE

This study aimed to evaluate the effects of statin therapy on serum levels of antibodies to several specific heat shock proteins (HSPs) in dyslipidemic patients.

DESIGN AND METHODS

Participants (n=102) were treated with simvastatin (40mg/day), or placebo in a randomized, double-blind, placebo-controlled, cross-over trial. Anti-HSP60, 65, 70, and hs-CRP levels were measured before and after each treatment period. Seventy-seven subjects completed the study.

RESULTS

Treatment with simvastatin was associated with significant reductions in serum anti-HSP60, 65, and 70 titers in the dyslipidemic patients (10%, 14%, and 15% decrease, respectively) (p<0.001). There have been previous reports of reductions in serum CRP with statin treatment, and although median CRP levels were 9% lower on simvastatin treatment, this did not achieve statistical significance.

CONCLUSION

While it is unclear whether HSP antibodies are directly involved in atherogenesis, our findings suggest that simvastatin inhibits autoimmune responses that may contribute to the development of cardiovascular disease
