Abstract

Metabolic syndrome is characterized by multiple metabolic disorders. Several studies indicated that curcumin plus piperine could affect lipids profiles in various diseases. The present meta-analysis aims to assess the effect of curcumin plus piperine on lipid profiles in patients with MetS and associated disorders using a systematic review and meta-analysis of randomized controlled trials. Trials were searched by several electronic databases up to May 2022. The Comprehensive Meta-Analysis (CMA) version3 software carried out this systematic review and meta-analysis. Random-effects model and the inverse variance method were used to conduct the meta-analysis. We evaluated the publication bias and heterogeneity of all eligible studies. In addition, subgroup analyses and sensitivity assessments were performed to assess potential sources of heterogeneity. The combined results by the random-effects model demonstrated that curcumin plus piperine significantly decreased total cholesterol and LDL-C in patients suffering from metabolic syndrome. In comparison, the results of the overall effect size did not show any significant change in triglyceride concentrations. Our results were robust in sensitivity analysis and were not dependent on the dose of curcumin, the dose of piperine, and the duration of treatment. Our results showed that co-administration of piperine and curcumin supplementation improves the lipid profile in metabolic syndrome. However, further long-term RCTs are required to ascertain their clinical benefit.
