BACKGROUND Previous studies have found that hyperuricaemia(HUA)is closely related to intestinal flora imbalance.AIM The current study investigated the effects and safety of washed microbiota transplantation(WMT)on serum uric acid(SUA)levels in different populations.METHODS A total of 144 patients who received WMT from July 2016 to April 2020 in the First Affiliated Hospital of Guangdong Pharmaceutical University and had SUA data before treatment were selected.Changes in SUA levels before and after treatment were retrospectively reviewed based on short-term and mid-term effects of WMT regimens.SUA levels measured in the last test within 3 mo after the first WMT represented the short-term effect,and SUA levels measured in the last test within 3-6 mo after the first WMT represented the mid-term effect.The patients were divided into an HUA group(SUA>416μM)and a normal uric acid(NUA)group(SUA≥202μM to≤416μM)based on pretreatment SUA levels.RESULTS Average short-term SUA levels in the HUA group decreased after WMT(481.00±99.85 vs 546.81±109.64μM,n=32,P<0.05)in 25/32 patients and returned to normal in 10/32 patients.The shortterm level of SUA reduction after treatment moderately correlated with SUA levels before treatment(r=0.549,R²=0.300,P<0.05).Average SUA levels decreased after the first and second courses of WMT(469.74±97.68 vs 540.00±107.16μM,n=35,and 465.57±88.88 vs 513.19±78.14μM,n=21,P<0.05).Short-term and mid-term SUA levels after WMT and SUA levels after the first,second and third courses of WMT were similar to the levels before WMT in the NUA group(P>0.05).Only 1/144 patients developed mild diarrhea after WMT.CONCLUSION WMT reduces short-term SUA levels in patients with HUA with mild side effects but has no obvious effect on SUA levels in patients with NUA.
