Montelukast and Budesonide for Childhood Cough Variant Asthma.

To determine the effects of combined treatment of montelukast and budesonide on young children with cough variant asthma, and their serum inflammatory factors of serum hypersensitive c-reactive protein (hs-CRP), tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6) and pulmonary function.An experimental study.The Second Affiliated Hospital of Xi'an Jiaotong University, China, from January 2016 to January 2017.A total of 112 children with cough variant asthma were randomly divided into observation group and control group with 56 cases in each group. All children were treated with antibiotics and resolving phlegm. The control group were given budesonide, while the observation group was treated additionally with montelukast. After the course, improvement time of clinical symptoms of cough, asthma, etc., changes in levels of serum inflammatory factors of hs-CRP, TNF-α and IL-6, and pulmonary function indexes of forced vital capacity (FVC), forced expiratory volume at the end of the first 1s (FEV1), peak expiratory flow (PEF), and observe concurrence of untoward effects in the two groups of sick children were compared.After treatment, extinction time for cough and for asthma of the observation group was less than those in the control group (all p<0.001). Levels of serum hs-CRP, TNF-α, IL-6 in the observation group were all lower than those of the control group (all p<0.001). Pulmonary function indices of FVC, FEV1 and PEF of the two groups of sick children were all higher than those of the control group (all p<0.001). During the treatment, there was no difference in the comparison of untoward effect rate of the two groups (p=0.696). After follow-up observation on the two groups of sick children for 1 year, the recurrence rate of the observation group was lower than that of the control group (p=0.026).Curative effects on young children with cough variant asthma of montelukast combined with budesonide are significant. The therapy may improve clinical symptoms and pulmonary function and reduce serum inflammatory factor level of sick children, with high application value and worthy of application and promotion.
