Children with non-specific cough (dry and non-productive cough without any other respiratory symptom, sign or systemic illness) are commonly treated with a variety of medications to treat the symptom of cough. This review examined whether there was any evidence for using leukotriene receptor antagonist in children with non-specific cough. There were two randomised controlled trials that included, but was not restricted to, children with non-specific cough, whereby no significant advantage over placebo was found in both studies. There is no RCT evidence to support the routine use of leukotriene receptor antagonist for the symptom of non-specific cough in children. Further research examining the effects of this treatment using child appropriate cough outcome measures is needed.
مطالعه چکیده کامل
Non-specific cough is defined as non-productive cough in the absence of identifiable respiratory disease or known aetiology. It is commonly seen in paediatric practice. These children are treated with a variety of therapies including a variety of asthma medications. The leukotriene pathway is reported to be involved in the sensory (neurogenic) pathway, which is a mechanism thought to be involved in the pathogenesis of chronic cough.
اهداف
To evaluate the effectiveness of leukotriene receptor antagonist (LTRA) in treating children with prolonged non-specific cough.
روشهای جستوجو
The Cochrane Register of Controlled Trials (CENTRAL), the Cochrane Airways Group Specialised Register, MEDLINE and EMBASE databases were searched by the Cochrane Airways Group. The latest searches were carried out in October 2010.
معیارهای انتخاب
All randomised controlled trials comparing LTRA with a placebo medication in children with non-specific cough.
گردآوری و تجزیهوتحلیل دادهها
Results of searches were reviewed against pre-determined criteria for inclusion. Two eligible trials that utilised montelukast were identified but no data was available for meta-analysis. It was not possible to separate results from children with non-specific cough from those without in one study and in the second, the groups were very small (5 in montelukast group and one in placebo group).
نتایج اصلی
There was no significant difference in all study endpoints between the montelukast and placebo groups (total N=256 plus 6 from second study).
نتیجهگیریهای نویسندگان
With the lack of evidence, the routine use of LRTA in treating children with non-specific cough cannot be recommended.
