ABSTRACT

Objective To explore the clinical curative effect of immunopotentiator combined with antiviral therapy in the treatment of children with recurrent respiratory tract infections.Methods 56 children with recurrent respiratory tract infections were selected as study subjects,and they were divided into two groups according to different therapeutic methods,28 cases in each group.The control group was given conventional antiviral treatment,the observation group was treated with immunopotentiator combined with antiviral therapy.The serum levels of IgA,IgG,IgM and peripheral blood T cell subsets CD3+,CD4+,CD8+ levels were detected in the two groups before treatment and after treatment.The fading away of the main symptoms and signs,and the clinical efficacy were observed.Results The fever subsided time [(1.98 ± 0.64) d],cough fade time [(1.65 ± 0.47) d] and lung's fading time [(2.38 ± 0.57) d] of the observation group were significantly shorter than those of the control group(all P ＜ 0.05).The total effective rate of the observation group was 92.86％,which was obviously higher than 67.86％ of control group(x2 =5.54,P ＜ 0.05).The serum immunoglobulin IgG [(9.09 ± 3.01) g/L],IgA [(1.75 ± 0.57) g/L],IgM [(1.39 ± 0.42) g/L] of the observation group after treatment had statistically significant differences compared with the control group (t =0.038,0.041,0.027,all P ＜0.05).The T lymphocyte subsets CD~ [(59.4 ± 8.9) ％],CD4+ [(40.5 ±4.4)％],CD8+ [(29.8 ± 4.7) ％] of the observation group after treatment had statistically significant differences compared with the control group (t =0.044,0.039,0.037,all P ＜ 0.05).Conclusion The application of immunopotentiator combined with antiviral therapy in the treatment of children with recurrent respiratory tract infections had exactly clinical curative effect,and it is worthy of popularization and application.
