Abstract
BACKGROUND
Rotavirus enteritis (RVE) is a disease that seriously affects the life and health of infants and young children worldwide. In recent years, it has been gradually recognized that intestinal flora disturbance plays an important role in the occurrence of RVE. However, there is little validation data on the effect of gut microbiota on the severity of illness and humoral immunity in children with RVE.
AIM
To analyze the correlation between intestinal flora and disease severity, intestinal mucosal barrier function, and humoral immunity in children with RVE.
METHODS
A total of 131 children with RVE diagnosed at our hospital from January 2019 to May 2021 were selected and divided into a mild group (39 cases), a moderate group (58 cases), and a severe group (34 cases) according to the severity of the disease. The number of intestinal bacteria and the distribution of dysbiosis grades were analyzed, and the relationship of the number of intestinal bacteria and dysbiosis grades with disease severity was analyzed. The intestinal mucosal barrier function indicators [serum D-lactic acid (D-LA), diamine oxidase (DAO), and endotoxin (ET)] and humoral immune indexes [serum immunoglobulin (Ig)A, IgG, and IgM] levels in children with different intestinal flora dysbiosis grades were measured, and the correlation between intestinal mucosal barrier function, humoral immunity, and the grade of intestinal flora imbalance was analyzed.
RESULTS
The number of intestinal bifidobacteria and lactobacilli was negatively correlated with the severity of the disease, while the number of intestinal Escherichia coli and the grade of dysbacteriosis were positively correlated with the severity of the disease (r = -0.727, -0.734, 0.757, and 0.748, respectively, P < 0.05). Serum D-LA, DAO, and ET were positively correlated with the grade of intestinal flora imbalance, and serum IgA, IgG, and IgM were negatively correlated with the grade of intestinal flora dysbiosis (r = 0.752, 0.717, 0.748, -0.715, -0.703 , and -0.787, respectively, P < 0.05).
CONCLUSION
The number of intestinal bacteria and the grade of disorders in children with RVE are significantly correlated with the severity of the disease, intestinal mucosal barrier function, and humoral immunity.
