Abstract: Objective To observe the health-related quality of life(HRQOL) of children with recurrent respiratory tract infection (RRTI)simultaneously inoculated by pneumococcal vaccine combined with influenza vaccine. Methods A total of 278 cases RRTI were randomly divided into two groups.The control group (n=135 patients) was used with placebo only while the vaccine group (n=143 patients) was simultaneously inoculated with pneumococcal vaccination combined with influenza vaccine.The PedsQL^TM 4.0 scores and clinical indicators were observed in each group before the inoculations; 14 months and 26 months after the inoculation. Results There were no significant differences in the number of cases, gender, age, duration and SES score in the two groups (P>0.05);The incidence of upper and lower respiratory tract infection, respiratory diseases caused by the frequency of fever, the number of days of antibiotic use and total cost of treatment in the vaccine group were significantly less than those of the control group (P<0.05);The PedsQL^TM 4.0 score showed no significant difference in both groups(P>0.05) before the inoculation;Each dimension of the quality of life of the vaccine group significantly increased as inoculation time extended (P<0.05), while those of control group showed no significant difference (P>0.05). Conclusion Combination of inoculation of pneumococcal vaccine and influenza vaccine can effectively improve the HRQOL of RRTI children as well as the PedsQL^TM 4.0 score and it should be highly recommended clinically.

摘要： 目的 观察肺炎球菌疫苗与流感疫苗联合接种对反复呼吸道感染(recurrent respiratory tract infection, RRTI)患儿健康相关生活质量(health-related quality of life, HRQOL)的影响。方法 278例RRTI患儿随机分为两组, 对照组(n=135例)仅使用安慰剂, 疫苗接种组(n=143例)联合接种肺炎球菌疫苗与流感疫苗, 观察两组患儿相关临床指标以及接种前、接种后14个月、接种后26个月时的PedsQL^TM 4.0评分。结果 两组患儿在例数、性别、年龄、病程及SES评分等方面比较差异无统计学意义(P>0.05);疫苗接种组患儿上、下呼吸道感染次数, 呼吸道疾病所致发热次数, 抗生素使用天数及总治疗费用均明显少于对照组(P<0.05);两组接种前PedsQL^TM 4.0评分比较差异无统计学意义(P>0.05), 疫苗接种组随接种时间延长, 各维度生活质量均明显提高(P<0.05), 而对照组差异无统计学意义(P>0.05)。结论 肺炎球菌疫苗与流感疫苗联合接种可有效改善RRTI患儿的HRQOL, 明显提高PedsQL^TM 4.0评分, 值得临床推广应用。
