Efficacy of artemisinin and its derivatives in animal models of type 2 diabetes mellitus: A systematic review and meta-analysis

Abstract

Although current evidence suggests that artemisinin and its derivatives play a multitarget therapeutic role in type 2 diabetes mellitus (T2DM), their efficacy and safety remain under debate. This meta-analysis aimed to evaluate the effects and safety of artemisinin and its derivatives in T2DM animal models. Preclinical studies that met the inclusion criteria were retrieved from PubMed, Embase, Web of Science, Scopus, CINAHL, OpenGrey, Google Scholar, Psyclnfo, British Library Ethos, ProQuest Dissertations & Theses, China National Knowledge Internet, VIP Information Chinese Periodical Service Platform, Chinese Biomedicine Literature Database, and Wanfang Data Knowledge Service Platform. Twenty-two studies involving 526 animals were included in the meta-analysis. The RevMan 5.3 and Stata 15.0, were used to perform the statistical analyses. The overall results showed that artemisinin or its derivatives could significantly reduce fasting plasma glucose, 2-h plasma glucose (2hPG) in the intraperitoneal glucose tolerance test (IPGTT), 2hPG in the intraperitoneal insulin tolerance test (IPITT), glycated hemoglobin A1c, under the curve in the IPGTT/IPITT, total cholesterol, triglyceride, low-density lipoprotein cholesterol, free fatty acid, and urine volume. Although increase in body weight was observed due to administration of the compounds, no significant effect was observed regarding serum insulin. In terms of adverse reactions, only two of the included studies reported that high-dose artemether may cause digestive inhibition in mice. Our results suggest that artemisinins could improve several parameters related to glycolipid metabolism in T2DM animal models. However, to evaluate the antidiabetic effects and safety of artemisinins in a more accurate manner, additional preclinical studies are necessary.
