CONCLUSIONS The results suggested that ezetimibe add-on to statin therapy is associated with an enhanced TNF-α-lowering effect  compared with statin monotherapy .
AIMS Statins are known to influence the status of adipokines , which play a key role in the pathophysiology of cardiometabolic diseases .
As the effect of ezetimibe as an add-on to statin therapy on the impact of statins on plasma adipokines levels is currently unclear , the aim of the present study was to investigate this through a meta- analysis of controlled trials .
Comparison of anti-inflammatory effects and high-density lipoprotein cholesterol levels between therapy with quadruple-dose rosuvastatin and rosuvastatin combined with ezetimibe
Background Statins are frequently administered to reduce low-density lipoprotein cholesterol ( LDL-C ) and vascular inflammation , because LDL-C and high sensitive C-reactive protein ( hs-CRP ) are associated with high risk for cardiovascular events . When statins do not reduce LDL-C to desired levels in high-risk patients with coronary artery disease ( CAD ) , ezetimibe can be added or the statin dose can be increased . However , which strategy is more effective for treating patients with CAD has not been established . The present study compares anti-inflammatory effects and lipid profiles in patients with CAD and similar LDL-C levels who were treated by increasing the statin dose or by adding ezetimibe to the original rosuvastatin dose to determine the optimal treatment for such patients . Methods 46 patients with high-risk CAD and LDL-C and hs-CRP levels of > 70 mg/dL and > 1.0 mg/L , respectively , that were not improved by 4 weeks of rosuvastatin ( 2.5 mg/day ) were r and omly assigned to receive 10 mg ( R10 , n = 24 ) of rosuvastatin or 2.5 mg/day of rosuvastatin combined with 10 mg/day of ezetimibe ( R2.5/E10 , n = 22 ) for 12 weeks . The primary endpoint was a change in hs-CRP . Results Baseline characteristics did not significantly differ between the groups . At 12 weeks , LDL-C and inflammatory markers ( hs-CRP , interleukin-6 , tumour necrosis factor-alpha and pentraxin 3 ) also did not significantly differ between the two groups ( LDL-C : R10 vs. R2.5/E10 : -19.4 ± 14.2 vs. -22.4 ± 14.3 mg/dL ) . However , high-density lipoprotein cholesterol ( HDL-C ) was significantly improved in the R10 , compared with R2.5/E10 group ( 4.6 ± 5.9 vs. 0.0 ± 6.7 mg/dL ; p < 0.05 ) . Conclusion Both enhanced therapies exerted similar anti-inflammatory effects under an equal LDL-C reduction in patients with high-risk CAD despite 2.5 mg/day of rosuvastatin . However , R10 elevated HDL-C more effectively than R2.5/E10.Trial registration
