Objectives: An evaluation the effects of curcumin on inflammatory markers and lipid profiles among patients with chronic kidney diseases (CKD).
Methods: The electronic databases such as PubMed, and Scopus were searched systematically up until 12 December 2021. To evaluate the quality of the included studies, the Cochrane risk-of-bias tool for randomized trials was utilized. Likewise, data pooling was performed using a random effects model, also called a variance components model. Also, the findings were calculated as weighted mean difference (WMD) with a 95% confidence interval (CI).
Results: In the end, this meta-analysis comprised a total number of nine studies. Curcumin intake significantly reduced total cholesterol (TC) (WMD=-13.77 mg/dL; 95% CI, -26.77, -0.77; p=0.04) and tumor necrosis factor alpha (TNF-α) (WMD=-18.87 pg/mL; 95% CI, -28.36, -9.38; p<0.001) compared with controls. The results did not confirm the significant effect of curcumin intake on triglyceride (TG) (WMD=-6.37 mg/dL; 95% CI, -26.59, 13.85; p=0.54), low-density lipoproteins (LDL-C) (WMD=-5.65 mg/dL; 95% CI, -20.81, 9.50; p=0.46), high-density lipoprotein (HDL-C) (WMD=0.16 mg/dL; 95% CI, -2.55, 2.88; p=0.91), and C-reactive protein (CRP) (WMD=-0.13 mg/L; 95% CI, -3.25, 3.30; p=0.93).
Conclusions: Our study showed that curcumin significantly impacts TC and TNF levels in CKD patients.
