Effects of combined vaccination on health related quality of life in children with recurrent respiratory infection / 中国小儿急救医学

ABSTRACT

Objective To observe the health-related quality of life of children with recurrent respiratory tract infection (RRTI) simultaneously inoculated by pneumococcal vaccine combined with influenza vaccine.Methods A total of 454 cases with RRTI were randomly divided into four groups,the control group (n =135) was used with placebo only,and the combined inoculation group (n =143) was simultaneously inoculated with pneumococcal vaccine combined with influenza vaccine,the pneumococcus vaccine group (n =95),influenza vaccine group (n =81).The PedsQLTM 4.0 score and clinical indicators were observed in each group before the inoculation and 14 months after the inoculation.Results There were no significant differences in the number of cases,gender,age,duration and socioeconomic status score in the four 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).And the combined inoculation group was significantly better than the pneumococcus vaccine group and influenza vaccine group(P ＜ 0.0l).The PedsQLTM 4.0 score showed no significant differences among four groups (P ＞ 0.05) before the inoculation.Each dimension of the quality of life of the vaccine group significantly increased (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 health-related quality of life of RRTI children as well as the PedsQLTM 4.0 score,and it should be highly recommended clinically.
