Age may determine the effect of hypolipidemic agents on plasma adipokine levels in patients with elevated low-density lipoprotein cholesterol levels
open access
Abstract
Introduction: Lipid-lowering agents affect adipose tissue function. No study has investigated the role of age in the effects of hypolipidaemic agents on plasma adipokines.
Material and methods: The study was a retrospective analysis of data of 65 hypercholesterolaemic patients treated for 90 days with simvastatin, ezetimibe, or simvastatin/ezetimibe combination therapy. Circulating levels of leptin, adiponectin, visfatin, and tumour necrosis factor alpha (TNF-alpha), as well as high-sensitivity C-reactive protein (hsCRP) were assessed separately for patients aged between 35 and 50 years and between 51 and 65 years, at the beginning and at the end of treatment.
Results: Patients in the age between 51 and 65 years had higher plasma levels of TNF-alpha and hsCRP, and lower plasma levels of adiponectin than patients aged between 35 and 50 years. In both age groups, simvastatin reduced plasma levels of hsCRP, leptin, visfatin, and TNF-alpha and increased circulating levels of adiponectin. This effect was particularly pronounced if simvastatin was administered in combination with ezetimibe. Ezetimibe alone increased plasma adiponectin and reduced plasma levels of leptin and hsCRP only in older adults. Irrespectively of age, ezetimibe administered alone did not affect visfatin and TNF-alpha. The effect of simvastatin on plasma hsCRP and the investigated adipokines did not differ between both groups. In turn, the effect of ezetimibe and simvastatin/ezetimibe combination therapy on leptin, adiponectin, and hsCRP was stronger in older than in younger adults.
Conclusions: Our results show that age may partially determine the effect of ezetimibe, but not of simvastatin, on adipose tissue function. (Endokrynol Pol 2016; 67 (3): 271–276)
