Abstract：【Objective】To investigate the changes and significance of T lymphocyte subsets and immunoglobulins and inflammatory factors in children with bronchitis after glucocorticoid therapy. 【Methods】A total of 80 children with bronchitis admitted to our hospital from January 2015 to August 2018 were selected as subjects. They were divided into two groups with 40 cases each according to different treatment methods. Patients in the control group received symptotherapy like anti-infective and expectorant, while patients in the observation group received symptomatic treatments based on budesonide atomization inhalation therapy.). Clinical efficacy and changes of immune system and inflammatory factors were compared between the two groups.. 【Results】The disappearing time of cough, dyspnea, dry/wet sound of lung and hospitalization time in the observation group were shorter than those in the control group (P<0.05). There was no significant difference in T lymphocyte subsets and immunoglobulin levels between the two groups before treatment (P>0.05). After treatment, the levels of CD3+, CD4+, CD4+/CD8+, immunoglobulin A (IgA) and immunoglobulin G (IgG) in the observation group were significantly higher than those in the control group, and the levels of CD8+ and immunoglobulin E (IgE) were significantly lower than those in the control group(P<0.05). Before treatment, there were no significant differences between the two groups in the levels of interleukin-4 (IL-4), IL-23, and eosinophil cationic protein (ECP) (P>0.05). After treatment, the levels of IL-4, IL-23 and ECP in the observation group were significantly lower in the group than in the control group (P<0.05).【Conclusion】Glucocorticoid therapy in children with bronchitis can promote the disappearance of clinical symptoms and signs, improve the immune function of children, inhibit the expression levels of serum IL-4,IL-23,ECP, and shorten hospitalization time.
