ABSTRACT
This meta-analysis aimed to compare the efficacy of montelukast (MKST) combined with budesonide (BUD) and BUD alone in the treatment of pulmonary inflammation and pulmonary function in children with cough variant asthma (CVA). Five electronic databases were searched for studies about MKST+BUD therapy and BUD alone therapy on inflammation and pulmonary function in CVA children from inception to November 23, 2021. Twenty-two articles were included. The results showed that, compared with BUD alone, the combination treatment could achieve better improvement of pulmonary function and lower levels of inflammation (MKST+BUD group: FEV1: SMD = 2.77, 95% CI: 2.07, 3.46; FVC: SMD = 2.54, 95% CI: 1.82, 3.27; PEF: SMD = 2.27, 95% CI: 1.79, 2.75; IgE: SMD = -7.95, 95% CI: -9.66, -6.25; TNF-α: SMD = -4.67, 95% CI: -6.04, -3.31; IL-8: SMD = -8.18, 95% CI: -11.46, -4.90; BUD alone group: FEV1: SMD = 1.83, 95% CI: 1.34, 2.31; FVC: SMD = 1.39, 95% CI: 0.93, 1.84; PEF: SMD = 1.51, 95% CI: 1.13, 1.89; IgE: SMD = -4.93, 95% CI: -6.14, -3.72; TNF-α: SMD = -2.78, 95% CI: -3.76, -1.80; IL-8: SMD = -4.94, 95% CI: -7.10, -2.79). To conclude, compared with BUD alone, MKST+BUD therapy was found to be more effective in improving pulmonary function and reducing inflammation in CVA children. Key Words: Montelukast, Budesonide, Cough variant asthma, Children, Pulmonary function, Inflammatory markers, Meta-analysis.
