BACKGROUND: The gut microbiota in patients with Graves' orbitopathy (GO) may influence the disease's progression, but its specific role and function in the progression of GO treatment are not well understood.
METHODS: We performed fecal microbiota sequencing using the 16S rRNA-gene sequencing on patients with GO (n = 48), Graves' disease (GD, n = 40), and healthy controls (HC, n = 36). Subsequently, fecal samples from patients with GO, GD, and healthy donors were transplanted into antibiotic-treated pseudo-germ-free mice. Finally, the 48 patients with GO were randomly divided into two groups: one group received intravenous glucocorticoids (ivGC) and atorvastatin (n = 24), while the other group received ivGC only (n = 24), to observe the effects of atorvastatin on GO progression and its impact on gut microbiota.
RESULTS: Patients with GO exhibit a distinct gut microbiota composition, particularly marked by increased levels of Prevotella and Bacteroides, compared to patients with GD and HC. Correlation analysis revealed a direct positive association between Prevotella and thyrotropin receptor antibody levels. Antibiotic-treated pseudo-germ-free mice that received fecal transplants from patients with GO exhibited a slower rate of weight gain, significant impairment of intestinal barrier integrity, and markedly increased levels of serum LBP and inflammatory factors. A combined treatment regimen of ivGCs and atorvastatin significantly reduced ocular clinical symptoms in patients with GO, including clinical activity score, exophthalmos, and intraocular pressure, while also promoting a healthier gut microbiota composition and a reduction in Prevotella levels.
CONCLUSIONS: Gut microbiota imbalance, particularly involving Prevotella, contributes to GO's development and progression. Atorvastatin may slow GO progression by correcting dysregulated gut microbiota, especially reducing Prevotella. Video Abstract.
