[Effects of diet on the gut microbiome in patients with depression].

Objective: To investigate the effects of diet on the gut microbiota and to assess the relationship of these factors with depression.

Material And Methods: Microorganisms that predominate in depressed patients were identified and associations of the identified organisms with the patients' diet were performed. Fourteen depressed patients and 14 healthy volunteers with the same socio-demographic parameters were included in the study. The Hamilton Depression Scale, Generalized Anxiety Disorder Questionnaire, and the Center for Epidemiologic Studies Questionnaire were used.

Results: and species were 11.3 and 14.4 times higher in depressed patients compared with healthy controls. and , as well as members of the genus were statistically significantly more abundant in the healthy volunteers group (6.5, 2.14, 8.75 and 5.2 times more frequently compared to patients). The presence of these microorganisms was correlated with dietary components.

Conclusion: Our study revealed groups of microorganisms that differ in healthy volunteers and depressed patients. The association of these microorganisms with the diet was shown, which partially confirmed the influence of a «healthy diet» on the development of depressive disorders.
