目的观察卡介菌多糖核酸注射液防治小儿反复呼吸道感染(RRTI)的疗效。方法将150例符合反复呼吸道感染诊断标准的患儿随机分为治疗组和对照组各75例。两组均酌情给予抗病毒及对症治疗。治疗组加用卡介菌多糖核酸注射液。比较两组治疗前后免疫球蛋白、血红蛋白水平及呼吸道感染次数。结果治疗组治疗后,免疫球蛋白、血红蛋白均高于对照组(P<005),且呼吸道感染次数明显减少(P<005)。结论卡介菌多糖核酸注射液防治小儿反复呼吸道感染疗效好,复发率低。
Objective To observe the efficacy of BCG polysaccharide nucleic acid injection in prevention and treatment of recurrent respiratory tract infections (RRTI) in children. Methods 150 cases of recurrent respiratory tract infection consistent with the diagnostic criteria of children were randomly divided into treatment group and control group of 75 cases. Both groups were given anti-virus and symptomatic treatment, as appropriate. Treatment group plus BCG polysaccharide nucleic acid injection. The levels of immunoglobulin, hemoglobin and respiratory tract infection were compared between the two groups before and after treatment. Results After treatment, the immunoglobulin and hemoglobin in the treatment group were significantly higher than those in the control group (P <005), and the number of respiratory infections was significantly decreased (P <005). Conclusion BCG polysaccharide nucleic acid injection in children with recurrent respiratory tract infection effective, low recurrence rate.
