Abstract
Objective
This systematic review explores the associations between qualitative/quantitative changes in gut microbiota and psychopathological symptoms or other clinical features in patients with eating disorders (EDs). Secondary outcomes include exploring gut microbiota changes in EDs and potential relationships with psychotropic drug use.
Method
A systematic search was conducted across biomedical databases from inception to June 2024 according to PRISMA guidelines. The risk of bias was assessed, and a narrative synthesis was performed due to the heterogeneity of the outcomes.
Results
Only findings related to anorexia nervosa (AN) were identified. Ten studies, of which seven were longitudinal, two cross-sectional, and one interventional (N = 350 patients with AN, and 304 HCs), were included. Despite no clear links between diversity metrics and clinical symptoms being observed, specific taxa belonging to phylum Firmicutes, such as Clostridium, Roseburia, Lactobacillus, Faecalibacterium, and Bifidobacterium belonging to Actinobacteriota correlated with ED psychopathology, including anxiety and depressive symptoms.
Conclusions
Changes in microbiota were related to anxiety and depressive symptoms, as well as altered eating behaviours by modulating inflammation and insulin pathways through short-chain fatty acids (SCFAs), that also lead to neurotransmitter imbalances. Further studies are required to replicate these finding and to explore whether similar patterns are observed in other EDs.
期刊介绍：
European Eating Disorders Review publishes authoritative and accessible articles, from all over the world, which review or report original research that has implications for the treatment and care of people with eating disorders, and articles which report innovations and experience in the clinical management of eating disorders. The journal focuses on implications for best practice in diagnosis and treatment. The journal also provides a forum for discussion of the causes and prevention of eating disorders, and related health policy. The aims of the journal are to offer a channel of communication between researchers, practitioners, administrators and policymakers who need to report and understand developments in the field of eating disorders.
