Objective: This study aims to understand the differences in intestinal flora, expression of helper T cells, allergy-related indicators, and cytokine levels between children with bronchial asthma and healthy children. The study seeks to clarify the effectiveness and safety of probiotic preparations in the treatment of bronchial asthma in children, and to provide new methods for the treatment of bronchial asthma. Methods: A total of 66 pediatric patients aged 3–6 years with bronchial asthma and 35 healthy children undergoing physical examination during the same period were enrolled, designated as the asthma group and the healthy group, respectively. The asthma group was further divided into the probiotic group and the non-probiotic group based on whether probiotics were used. The gut microbiota, serum IgE antibody levels, cytokines (IL-4, IL-5, IL-9, IL-13 levels), proportions of helper T cells (Th1, Th2), and hypersensitive C-reactive protein were measured and compared among the groups. Results: Children with bronchial asthma had decreased abundance and reduced diversity of intestinal flora compared to the healthy group. At the genus level, the asthma group showed increased abundance of Bacteroides and decreased abundance of Faecalibacterium and Veillonella; The probiotic group demonstrated a significantly higher improvement in the abundance of these genera before and after treatment compared to the non-probiotic group (P |
