This study conducted a systematic review and meta-analysis to evaluate the effect of statin therapy in combination with ezetimibe on CRP and hs-CRP levels. The results showed that the combination therapy significantly reduced the levels of hs-CRP and overall CRP, suggesting its potential in suppressing inflammation.
Background Previous studies have reported that statin or ezetimibe therapy has an anti-inflammatory effect. However, the results of individual studies on the effect of statin therapy in combination with ezetimibe on C-reactive protein (CRP) and high-sensitivity CRP (hs-CRP) levels have not been clear. Therefore, the present systematic review and meta-analysis were conducted on randomized clinical trials (RCTs) to evaluate the effect of statin therapy in combination with ezetimibe on CRP and hs-CRP levels. Methods A literature search was carried out on the MEDLINE, SciVerse Scopus, and Clarivate Analytics Web of Science databases up to February 2022 to find eligible studies. The pooled effect sizes were considered for weighted mean difference (WMD) and 95% confidence intervals (CI) for CRP and hs-CRP, and it was also determined as standardized weighted mean difference (SMD) for overall CRP. For all variables, a random-effects model was used. Results Of the 57 studies included in the systematic review, 53 were used for meta-analysis. Statin therapy in combination with ezetimibe significantly reduced the serum levels of hs-CRP (WMD - 0.2 mg/l; 95% CI - 0.4, - 0.1, P < 0.001) and overall CRP (SMD - 0.16 mg/l; 95% CI - 0.2, - 0.07, P < 0.001). Nevertheless, CRP levels were not significantly changed by combination therapy. A significant association was observed between the serum low-density lipoprotein cholesterol (LDL-C) changes and hs-CRP levels, which can justify the source of heterogeneity. Conclusions The current study showed that statin therapy in combination with ezetimibe could be effective in reducing the levels of hs-CRP and overall CRP. [GRAPHICS] .
