Abstract:
Objective:To study the interaction effects between intestinal microflora features with serum inflammatory factors and homeostatic model assessment insulin resistance (HOMA-IR) in patients with first-episode untreated schizophrenia (SCZ).Methods:A total of 79 SCZ patients admitted to Suining Central Hospital from August 2016 to August 2019 were selected as observation group, and 60 healthy examiners were set as control group. The intestinal microflora, serum inflammatory factors and glucose metabolism indexes of the two groups were detected and compared. The correlation between intestinal microflora and inflammatory factors and HOMA-IR was analyzed.Results:The content of bifidobacteria in the observation group was lower than that in the control group while the content of bacteroides was higher than that in control group; the levels of serum inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-6] and in the observation group were higher than those in the control group ( P<0.05); the level of HOMA-IR in the observation group was higher than that in control group ( P<0.05). The TNF-α, IL-1β, IL-6 and HOMA-IR in SCZ patients were significantly negatively correlated with intestinal bifidobacteria content ( P<0.05), and were obviously positively correlated with bacteroides content ( P<0.05). Conclusions:In first-episode untreated SCZ, the content of bifidobacteria decreased and the content of bacteroides increased, and there was a significant correlation with inflammatory factors and HOMA-IR, which may lead to the disorder of glucose and lipid metabolism and induce the occurrence of metabolic diseases such as diabetes.
