ABSTRACT

Objective To investigate the therapeutic effects of salmeterol xinafoate and fluticasone propio-nate powder(seretide) in combination with montelukast on children with cough variant asthma (CVA),and its effect on pulmonary function and serum inflammatory cytokines .Methods 200 patients with CVA were enrolled ,and they were randomly divided into two groups according to the random number table ,100 cases in each group .The control group was treated with seretide ,while the observation group was treated with seretide and montelukast sodium ,both two groups were treated for 3 months.The clinical efficacy,pulmonary function and serum inflammatory cytokines were compared between the two groups .Results The total effective rate of the observation group ( 88.3％) was significantly higher than that of the control group (70.3％;χ2 =9.146,P<0.05).The duration of remission and disappearance of cough symptoms in the observation group were (5.45 ±1.32) d,(8.63 ±1.96) d,respectively, which were significantly shorter than those in the control group [(7.33 ±2.46) d,(12.61 ±1.84) d;t =6.505, 14.229,all P<0.05].There were no statistically significant differences in FEV 1,FEV1/FVC,PEF,IgE,TNF-αand IL-17 between the two groups before treatment (all P>0.05).After treatment,the levels of FEV1,FEV1/FVC, PEF were all significantly higher than those before treatment [(2.11 ±0.34) L,(73.71 ±11.44)％,(86.34 ± 7.85)％,t=18.149,7.664,19.196,all P<0.05;(1.82 ±0.35)L,(69.36 ±10.79)％,(81.66 ±8.03)％,t=9.312,5.418,13.627,all P <0.05],and IgE,TNF -α,IL -17 levels were significantly decreased [(141.3 ± 38.2)ng/L,(624.7 ±213.2) ng/L,(6.1 ±2.1) ng/L,t =15.200,13.708,15.881,all P <0.05;(191.5 ±41.9) ng/L,(835.5 ±326.3)ng/L,(9.4 ±2.7) ng/L,t=6.784,6.206,8.550,all P<0.05].The differences between the two groups were statistically significant(t=5.717,2.659,4.008,8.521,4.842,9.296,all P<0.05). Conclusion Salmeterol xinafoate and fluticasone propionate powder in combination with montelukast sodium has excellent clinical effect in the treatment of children with CVA ,which can improve the pulmonary function and reduce inflammatory cytokines .
