ARTICLE HIGHLIGHTS
Research background

Previous studies suggested that free fatty acid (FFA) concentration was potentially associated with anti-diabetic drugs of sulfonylurea (SU). The results were inconsistent. We assessed the effects of SU on the level of FFA concentration in diabetic patients.

Research motivation

SU is one of the most commonly used anti-diabetic medications. Several studies reported that SU treatment increased the risk of cardiovascular death and stroke in diabetic patients. Despite the reason for this result is unclear but may be related to the effect of SU on FFA and blood lipids.

Research objectives

The primary objective was to perform a meta-analysis of diabetic patients treated with SU and analyze changes in FFA concentration.

Research methods

We reviewed PubMed, EMBASE, Cochrane Library, Reference Citation Analysis (https://www.referencecitationanalysis.com/), and Web of Science databases to identify studies using SU for diabetic patients. The FFA value change was measured. A random-effect model or fixed-effect model was used according to the test of heterogeneity, and I2 index was used to assess the heterogeneity.

Research results

We included 13 observational studies comprising 16 treatment arms in the meta-analysis. FFA concentration was increased after the treatment of SU in diabetic patients. When combined with other antidiabetics, the effects of SU treatment on FFA concentration were more pronounced. There was no significant different effect of FFA concentration when treated with glimepiride or glibenclamide.

Research conclusions

Some SU drugs increased serum FFA concentration in diabetic patients.

Research perspectives

The association between FFA concentration and SU treatment requires more studies and longer follow-up.
