dc.description.abstractSimvastatin can modulate lipid and bone metabolism. However, information related to the interaction between diet and simvastatin on bone structure and biomechanics is scarce. Thus, this study evaluated the effects of simvastatin on femoral biomechanics and cortical/trabecular bone structure in wild-type mice nourished with a hyperlipidic diet. Three-month-old male wild-type mice (C57BL6 strain) were divided into four groups: (1) group W, nourished with a standard diet; (2) group WH, fed a hyperlipidic diet; (3) group WS, nourished with a standard diet plus oral simvastatin (20 mg/kg/day); and (4) group WHS, fed a hyperlipidic diet plus oral simvastatin (20 mg/kg/day). All animals received only their specific diet and water for 60 days. Blood samples were collected for the analysis of calcium, triglycerides, total cholesterol (TC) and fraction serum levels. Diet manipulation was able to induce a dyslipidaemic status in mice, characterized by triglyceride and TC rise in WH animals. Simvastatin prevented hypercholesterolaemia and reduced TC and LDL serum levels, but did not prevent hypertriglyceridaemia and HDL serum levels in the WHS group. In the WH mice the hyperlipidaemia was associated with reduction in trabecular bone thickness, femur structural and material property alterations. Simvastatin prevented these morphological alterations and minimized femur biomechanical changes in WHS mice. Taken together, the results indicated that the hyperlipidic diet intake acts as a risk factor for bone integrity, generating bones with reduced resistance and more susceptible to fractures, an effect attenuated by simvastatin that is potentially related to the modulatory action of this drug on lipid and bone metabolism.en
