[Clinical effect of fluticasone propionate, montelukast sodium and ketotifen in treatment of cough variant asthma in children]. OBJECTIVE: To study the clinical effect of different combinations of fluticasone propionate (Flu), montelukast sodium (Mon) and ketotifen (Ket) in the treatment of children with cough variant asthma (CVA). METHODS: A total of 280 children with CVA who were admitted to the department of respiratory medicine from June 2015 to January 2018 were randomly divided into Flu+Mon+Ket, Flu+Mon, Flu+Ket, Mon+Ket, Flu, Mon and Ket groups, with 40 children in each group. The children in each group were given corresponding drug(s), and the course of treatment was 3 months for all groups. The condition of cough, cough symptom score, pulmonary function and adverse drug reactions were evaluated after 2 and 3 months of treatment. The children were followed up to observe recurrence. RESULTS: After treatment, cough symptom score tended to decrease in all 7 groups, with increases in percentage of forced expiratory volume in 1 second (FEV1%) and percentage of predicted peak expiratory flow (PEF%). After 2 months of treatment, the Flu+Mon+Ket group had a significantly lower cough symptom score and significantly higher FEV1% and PEF% than the other groups (P<0.05). After 2 and 3 months of treatment, the Ket group had a significantly higher cough symptom score and significantly lower FEV1% and PEF% than the other groups (P<0.05). After 3 months of treatment, there were no significant differences in cough symptom score, FEV1% and PEF% among the other groups (P>0.05). There was a low incidence rate of adverse events in all 7 groups, and there was no significant difference among the 7 groups (P>0.05). The Ket group had a significantly higher recurrence rate of cough than the other groups (P<0.001), while there was no significant difference in this rate among the other groups (P>0.0024). CONCLUSIONS: For children with CVA, a combination of Flu, Mon and Ket has a better clinical effect than a combination of two drugs and a single drug at 2 months of treatment and is safe. After 3 months of treatment, Flu or Mon alone has a similar effect to drug combination. Ket alone has a poor clinical effect and a high recurrence rate after drug withdrawal.
