Abstract

|
Aster glehni extracts (AGE) reduced serum uric acid levels in hyperuricemia rats in several previous studies. However, its efficacy in human has not been yet explored. This study aimed at investigating the efficacy and safety of AGE on the anti-hyperuricemia effect in subjects with slightly high serum uric acid. A randomized, double-blinded, placebo-controlled clinical trial was conducted for 12 weeks. Eligible subjects were randomly assigned to either AGE (480?mg/day) or placebo. The primary endpoint was the change in serum uric acid concentrations from baseline to follow-up time points. The secondary endpoints were the change of serum xanthine oxidase activity, and the levels of C-reactive protein (CRP) and tumor necrosis factor alpha (TNF-α) in the blood from baseline to follow-up time points. Safety was assessed by clinical laboratory parameters and adverse events reported by subjects. Six weeks of AGE supplementation significantly reduced serum uric acid level from baseline (P?=?.0468) but at the end of the intervention the participants did not show the beneficial effect of AGE supplementation. Also, the serum uric acid level in the AGE group was not significantly different at the follow-up time points, when compared with placebo. The mean changes of secondary endpoints from baseline to each time point did not show significant differences within and between the two groups. There were no adverse events reported by subjects or changes in safety parameters after intervention. In conclusion, AGE supplementation for 12 weeks did not show significant benefits for reducing serum uric acid concentrations in subjects with mild hyperuricemia.
