Correlations of Inflammatory Factors with Intestinal Flora and Gastrointestinal Incommensurate Symptoms in Children with Asthma

BACKGROUND: Bronchial asthma is a common pediatric disease, the pathogenesis of which is complicated. The correlations of the levels of inflammatory factors in peripheral serum with intestinal flora and gastrointestinal incommensurate symptoms in children with asthma remain to be further elucidated. MATERIAL/METHODS: A total of 70 children diagnosed with asthma in the Pediatric Department of our hospital from February 2016 to March 2017 were enrolled as an observation group, and another 25 healthy children in the same age range were selected as a control group. The levels of inflammatory factors [C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6)], the total load of intestinal flora, and the main strains were detected among all included patients. Moreover, incommensurate symptoms of patients in the observation group were recorded and gastrointestinal symptom rating scale (GSRS) scores were calculated. The differences in indexes between the observation group and the control group were compared. RESULTS: The levels of CRP, TNF-α, and IL-6 in peripheral serum in the observation group were significantly higher than those in the control group (p<0.05). The analysis of the correlations of inflammatory factors in peripheral serum with intestinal flora and GSRS scores showed that C-reactive protein (CRP) was positively correlated with GSRS scores (r=0.696, p<0.001) and the total load of intestinal bacteria (r=0.813, p<0.001). CONCLUSIONS: The inflammatory factors in peripheral serum of children with asthma are closely correlated with intestinal flora and gastrointestinal function. With the increasingly high levels of inflammatory factors in peripheral serum, the probability of intestinal flora disturbance and gastrointestinal incommensurate symptoms will be increased.
