IntroductionUnderstanding factors related to generalized anxiety disorder pathogenesis is critical for elucidating the mechanism and preventing its establishment. Intestinal flora and hereditary factors such as brain-derived neurotrophic factor (BDNF) gene polymorphism may have a role in the development of generalized anxiety disorder. This work explored the relationship between intestinal flora, inflammatory changes and BDNF gene polymorphisms and the occurrence of generalized anxiety disorder.MethodsForty-eight patients with generalized anxiety disorder and 57 healthy people were included in the study. As the disease group and control group, the polymorphisms of rs10767664 and rs7124442 of the BDNF gene, differences in the distribution of intestinal flora, and changes in inflammatory and immune indicators were analyzed.ResultsThe distribution of BDNF gene alleles, genotypes and haplotypes in the disease group were different from those in the control group. The levels of TNF-α (P = .000), interleukin-4 (P = .000), interleukin-10 (P = .043) and IgG (P = .008) in patients with generalized anxiety disorder in the disease group were different from those in the control group. The distribution of gut microbes in patients with generalized anxiety disorder in the disease group was different from that in the control group.ConclusionThe onset of generalized anxiety disorder is related to BDNF gene polymorphism, and is accompanied by changes in intestinal flora and inflammatory immune status in the body.Copyright © 2022 the Author(s).
