ABSTRACT
Objective To investigate the effect of microecological therapy on rotavirus ( RV)-induced diarrhea and infants’ immunologic function in infants. Methods 150 infants with RV diarrhea were randomly divided into the ex-perimental group and the control group. The control group was given the treatment of montmorillonite powder. The experimental group was given live combined bifidobacterium and lactobacillus tablets in addition to montmorillonite powder. The clinical efficacy and the improvement of clinical symptoms were compared between the two groups. RV antigen and immunologic function were detected with colloidal gold method. Immune function was detected by flow cytometry and ELISA. Results The total effective rate of the experimental group was 90.7%,and it was significant-ly higher than that of the control group which was 74.7%(P＜0.05). Compared with the control group, the antidi-arrheal time, fever clearance time and disappearance time of vomiting symptoms in the experimental group were shorter ( P＜0.05) . The negative conversion rate of RV virus antigen in the experimental group after 1 and 2 weeks treatment was significantly higher than that in the control group ( P＜0.05) . After 3 weeks treatment, RV virus antigen in the experimental group all turned negative, but the control group still had a positive rate of 12.0% ( P＜0.05) . The peripheral blood CD3+, CD4+and the ratio of CD4+/CD8+in the experimental group after treatment were significantly higher than those before treatment and those in the control group after treatment ( P＜0.05) , the same phenomenon was found in serum immunoglobulin A ( IgA) and IgM ( P＜0.05) . No adverse events occurred during the treatment period in the two groups. Conclusions Microecological therapy has an exact curative effect and high safety in the treatment of infantile RV diarrhea, it could effectively improve the immunologic function of the infants.
