A Study of the Efficacy of Fecal Microbiota Transplantation(FMT) in the Treatment of Schizophrenia

The purpose of this study was to explore whether repeated oral fecal capsules could improve outcomes in patients with schizophrenia receiving conventional antipsychotic drugs. This study was divided into screening period (1 week) and treatment period (8 weeks). Subjects who met the inclusion criteria during the screening period entered the treatment period. During the treatment period, the patients were divided into two groups: oral fecal bacteria capsules + antipsychotics group; Oral placebo + antipsychotic group. During the follow-up period, both groups were treated with stable dose of antipsychotic drugs during the treatment period. Before and after the intervention, venous blood samples of patients were collected for routine tests such as liver and kidney function to determine the safety of treatment. The scale evaluated the improvement of patients\' psychotic symptoms to determine the efficacy and safety of FMT combined with antipsychotics.
