Insights
Berberine effectively treats dyslipidemia by improving lipid profiles, including reducing total cholesterol (TC) and triglycerides (TG). This natural compound demonstrates good safety, with no significant increase in adverse events compared to controls.
Area of Science:
- Cardiovascular Pharmacology
- Natural Product Therapeutics
- Evidence-Based Medicine
Background:
- Dyslipidemia poses a significant risk factor for cardiovascular diseases.
- Current lipid-lowering drugs have limitations and potential side effects.
- Berberine, a natural alkaloid, has shown potential in managing lipid metabolism.
Purpose of the Study:
- To systematically review and meta-analyze the clinical efficacy and safety of berberine for dyslipidemia.
- To assess berberine's impact on lipid profiles (TC, TG, LDL-C, HDL-C) and adverse events.
Main Methods:
- Comprehensive literature search across multiple databases (PubMed, Embase, Cochrane, etc.) up to January 2019.
- Inclusion of 25 randomized controlled trials (RCTs) involving 3,042 patients.
- Meta-analysis using RevMan 5.3 software, with subgroup analyses for interventions.
Main Results:
- Berberine, alone or with conventional drugs, significantly reduced total cholesterol (TC), triglycerides (TG), and LDL-C.
- Berberine significantly increased HDL-C levels compared to control groups.
- No statistically significant difference in adverse event incidence was observed; no severe adverse effects were reported.
Conclusions:
- Berberine demonstrates significant efficacy and a favorable safety profile in managing dyslipidemia.
- High heterogeneity and low methodological quality of included trials necessitate further validation.
- High-quality, large-scale, multi-center clinical trials are recommended to confirm these findings.
Abstract:
To evaluate the clinical efficacy and safety of berberine in the treatment of dyslipidemia. In this review, CNKI, WanFang, VIP, CBM, PubMed, Cochrane Library, EMbase, and Medline(OVID) were retrieved from database establishment to January, 2019 in any language. Randomized controlled trials(RCTs) of berberine with or without lipid-lowering drugs vs placebo, without drugs or lipid-lowering drugs only in treatment of dyslipidemia were collected. Data extraction and paper quality assessment were conducted according to the Cochrane Handbook. Then RevMan 5.3 software was used for Meta-analysis. A total of 25 trials were included, covering 3 042 cases, including 1 552 cases in the experimental group and 1 490 cases in the control group. The clinical heterogeneity of the included trials was relatively high, and the methodological quality of most trials was generally low, with bias in terms of random sequence generation, allocation hiding, blind method and result data. Interventions were divided into different subgroups for analysis. Meta-analysis suggested that use berberine alone or along with lipid lowing drugs could reduce TC, TG, LDL-C levels and increased HDL-C levels with statistically significant difference as compared with control group. As compared with control group, there was no statistically significant difference in the incidence of adverse events. No severe adverse effects were reported in all trials. Berberine has good efficacy and safety in the treatment of dyslipidemia. Due to the quality limitations of the included trials, the above conclusions need to be further verified by high-quality, large sample size and multi-center clinical trials.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
