Effect of Montelukast on the Expression and Variation of TGF-β for Children With Mild Persistent Asthma

Asthma Clinical Trial

Clinical Trial Summary

The Objective of our research is to observe the effect of cysteinyl leukotriene receptor antagonist on the expression and variation of TGF-β1 levels and mRNA expression in children with mild persistent asthma in their plasma and T lymphocyte, to discuss the role of TGF-β1 in the pathogenesis of bronchial asthma in children and to evaluate the function of regulation of leukotriene receptor antagonist on asthma in children.

Clinical Trial Description

The majority pediatric asthma patients in Shanghai are mild persistent asthma. These patients require controller medications every day to achieve and maintain control. Leukotriene receptor antagonist is one of the options which have been recommended to use as a mono controller therapy. Patient satisfaction and compliance was better with montelukast, attributed to oral intake and convenience. Owing to its easy and simple oral once a day administration montelukast was found to be advantageous over ICS. On the other hand, recent studies have shown that there is a considerable degree of airway remodeling in peripheral airways in patients with mild asthma.The new information points out the need for large, long term studies on the treatment of mild persistent asthma, with an emphasis on exacerbations, remodeling, and the relationship between these outcomes and markers of asthma control. TGF-β participates in the initiation and propagation of inflammatory and immune responses in the airways. The leukotrienes exert their biologic actions by binding to and activating specific receptors. Montelukast, a cysteinyl leukotriene 1(CysLT1) receptor antagonist, acts on LTC4, LTD4 and LTE4, and, therefore, on airway inflammation and bronchoconstriction. Some results suggest that low dose of Montelukast may modulate the parameters of inflammation and fibrosis.In this study we try to determine the effects of lower dose Montelukast on the expression and variation of TGF-β in induced sputum and T lymphocyte for children with mild persistent Asthma.

Drug in the study provide by MSD. We have done induced sputum procedure in our past study. Reagent can be bought from company. ;
