Abstract:Objective To investigate the clinical efficacy of Bifidobacterium Lactobacillus triple live tablets combined with racecadotril in children with rotavirus diarrhea.Methods A total of 120 pediatric patients with rotavirus-induced diarrhea admitted to the Chengdu Public Health Clinical Medical Center from June 2022 to June 2025 were selected as the study subjects. Using a simple randomization envelope drawing method, they were randomly divided into a routine group (n = 60) and a combination group (n = 60). The routine group received standard treatment, while the combination group received additional Bifidobacterium Lactobacillus triple live tablets and racecadotril. Clinical efficacy, symptom improvement, immune indicators [immunoglobulin A (IgA), IgG, IgM], intestinal flora composition, and gastrointestinal hormone [gastrin (GAS), motilin (MOT), and vasoactive intestinal peptide (VIP)] levels were compared between the two groups.Results The overall effective rate was significantly higher in the combination group than in the routine group (P < 0.05). The time to diarrhea cessation, vomiting cessation, fever abatement, and normalization of stool consistency were all shorter in the combination group (P < 0.05). After treatment, the levels of IgA, IgG, and IgM were significantly higher in the combination group than in the routine group (P < 0.05). The differences in IgA, IgG, and IgM levels before and after treatment were greater in the combination group than in the routine group (P < 0.05). After treatment, the content of Enterobacteriaceae was significantly lower in the combination group (P <0.05), while the contents of Bifidobacterium and Lactobacillus were significantly higher in the combination group compared to the routine group (P < 0.05). The differences in Enterobacteriaceae, Bifidobacterium, and Lactobacillus contents before and after treatment were greater in the combination group than in the routine group (P < 0.05). After treatment, the levels of GAS, MOT, and VIP were significantly lower in the combination group than in the routine group (P < 0.05). The differences in GAS, MOT, and VIP levels before and after treatment were greater in the combination group than in the routine group (P < 0.05).Conclusion Bifidobacterium Lactobacillus triple live tablets combined with racecadotril exert a significant therapeutic effect on rotavirus diarrhea in children.
