Abstract:
Objective:To explore the effect of probiotics on the cognitive function of patients with schizophrenia.Methods:100 schizophrenic patients admitted to Shanghai Jinshan District Mental Health Center from January 2019 to January 2021 were randomly divided into the conventional group (treated with atypical antipsychotics combined with placebo, 50 cases) and the intervention group (treated with atypical antipsychotics combined with probiotics, 50 cases). Before treatment and 3 months after treatment, the feces of the patients were taken for DNA detection to compare the composition of intestinal flora. The cognitive function of the patients was assessed by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), and the mental state of the patients was assessed by the Positive and Negative Symptom Scale(PANSS). The incidence of adverse drug reactions was compared between the two groups.Results:Before treatment, the relative abundance of Fusobacteria, Proteus and Actinobacteria in the two groups had no statistical significant difference (all P>0.05); After 3 months of treatment, the relative abundance of Fusobacteria, Proteus and Actinobacteria in the two groups decreased compared with that before treatment, and the decline was more significant in the intervention group (all P<0.05). Before treatment, there was no significant difference in immediate memory, visual span, speech function, attention function, delayed memory and RBANS between the two groups (all P>0.05); After 3 months of treatment, the scores of immediate memory, visual span, speech function, attention function, delayed memory and RBANS in the two groups were higher than those before treatment, and the increase was more significant in the intervention group (all P<0.05). Before treatment, there was no significant difference in PANSS scores between the two groups ( P>0.05); After 3 months of treatment, PANSS scores in both groups decreased compared with those before treatment, and the decrease degree in the intervention group was higher than that in the conventional group (all P<0.05). During the three months of treatment, there was no significant difference in the incidence of adverse drug reactions between the two groups ( P>0.05). Conclusions:Probiotics are used in adjuvant therapy for patients with schizophrenia, which can regulate the patients′ intestinal flora, improve patients′ cognitive function and mental disorders, and do not increase the incidence of adverse drug reactions. They have significant clinical efficacy and high treatment safety.
