Data on the effect of grape seed extract (GSE) on lipid profiles are inconclusive. We undertook a systematic review and meta-analysis of randomised controlled clinical trials on the effect of GSE on serum lipid profiles. The online databases of PubMed, ISI Web of Science, Scopus, ProQuest, Science Direct and Embase were searched for relevant publications until March 2019, using MeSH and non-MeSH keywords. Study selection, data extraction and quality assessment were completed independently by two investigators. Meta-regression and subgroup analyses were performed to identify the source of heterogeneity. Assessment of study quality was conducted using the Jadad scale. Eleven randomised clinical trials involving 536 participants were included in the present meta-analysis. Combining effect sizes from earlier studies, we found that GSE supplementation significantly decreased serum levels of LDL-cholesterol (−0·17 mmol/l; 95 % CI −0·34, −0·01) and TAG (−0·11 mmol/l; 95 % CI −0·18, −0·05). Although no overall significant effect of GSE supplementation on circulating total- and HDL-cholesterol levels was observed, there were significant reductions in these lipids in studies with <10 weeks of intervention and those that had administered the dosages of <300 mg/d of GSE. In conclusion, GSE supplementation seems to favourably affect serum levels of LDL and TAG concentrations, but it did not affect total- and HDL-cholesterol concentrations.

葡萄籽提取物对血脂异常的影响:随机对照试验的系统评价和剂量反应荟萃分析

关于葡萄籽提取物 (GSE) 对脂质分布的影响的数据尚无定论。我们对 GSE 对血脂谱影响的随机对照临床试验进行了系统回顾和荟萃分析。在 PubMed、ISI Web of Science、Scopus、ProQuest、Science Direct 和 Embase 的在线数据库中,使用 MeSH 和非 MeSH 关键词搜索了截至 2019 年 3 月的相关出版物。研究选择、数据提取和质量评估由两名研究者独立完成。进行元回归和亚组分析以确定异质性的来源。使用 Jadad 量表对研究质量进行评估。本荟萃分析包括 11 项随机临床试验,涉及 536 名参与者。结合早期研究的影响大小,我们发现补充 GSE 可显着降低 LDL 胆固醇(−0·17 mmol/l;95% CI −0·34、−0·01)和 TAG(−0·11 mmol/l;95% CI −)的血清水平0·18,-0·05)。虽然没有观察到补充 GSE 对循环总胆固醇和高密度脂蛋白胆固醇水平的总体显着影响,但在干预时间小于 10 周的研究中以及那些给予 GSE 剂量小于 300 mg/d 的研究中,这些脂质显着降低. 总之,GSE 补充剂似乎对 LDL 和 TAG 浓度的血清水平有有利影响,但它不影响总胆固醇和 HDL 胆固醇浓度。虽然没有观察到补充 GSE 对循环总胆固醇和高密度脂蛋白胆固醇水平的总体显着影响,但在干预时间小于 10 周的研究中以及那些给予 GSE 剂量小于 300 mg/d 的研究中,这些脂质显着降低. 总之,GSE 补充剂似乎对 LDL 和 TAG 浓度的血清水平有有利影响,但它不影响总胆固醇和 HDL 胆固醇浓度。虽然没有观察到补充 GSE 对循环总胆固醇和高密度脂蛋白胆固醇水平的总体显着影响,但在干预时间小于 10 周的研究中以及那些给予 GSE 剂量小于 300 mg/d 的研究中,这些脂质显着降低. 总之,GSE 补充剂似乎对 LDL 和 TAG 浓度的血清水平有有利影响,但它不影响总胆固醇和 HDL 胆固醇浓度。
