Abstract:
Objective To explore the effect of fecal microbiota transplantation(FMT)combined with probiotics on cognitive function and intestinal barrier function in elderly patients with mod-erate Alzheimer's disease(AD).Methods A total of 184 elderly patients with moderate AD ad-mitted in the First Affiliated Hospital of Nanyang Medical College from January 2021 to June 2023 were enrolled,and randomly divided into control group(92 cases)and study group(92 ca-ses).The control group received treatment with memantine hydrochloride,while the study group was given memantine hydrochloride and FMT combined with probiotics.The changes in cognitive function related indicators,inflammatory factors,oxidative stress and intestinal barrier function indicators were compared before and after treatment and between the two groups.Results After treatment,the ADAS-cog scores and Activities of Daily Living(ADL)score were significantly de-creased,the scores of Simple Intelligence Status Examination Scale(SISES)was obviously in-creased in both groups(P＜0.05).The study group had notably lower ADAS-cog and ADL scores,and higher SISES score than the control group after treatment(P＜0.01).The levels of TNF-α,IL-6,IL-8,MAD and homocysteine after treatment were notably lower(9.1±2.1 ng/L vs 11.3±2.2 ng/L,P=0.027;11.1±3.4 μg/L vs 16.5±3.1 μg/L,P=0.000;21.0±4.7 μg/L vs 27.2±5.0 μg/L,P=0.000;6.3±1.2 μmol/L vs 7.0±1.3 μmol/L,P=0.009;38.2±4.8 μg/L vs 45.7±6.2 μg/L,P=0.000),and SOD level was remarkably higher(104.3±8.9 U/L vs 80.2±7.5 U/L,P=0.000)in the study group than the control group.In the study group,the levels of MAD and homocysteine were decreased,while that of SOD was increased after treatment(P＜0.05).The levels of endotoxin,diamine oxidase,and urinary lactulose/mannitol ratio in the study group were significantly lower than those in the control group after treatment(P＜0.05,P＜0.01).Conclusion FMT combined with probiotics can significantly improve cognitive function and in-testinal barrier function in elderly patients with moderate AD.
