Effects of Montelukast in Asthmatic Children With and Without Food Allergy

Overview[ - collapse ][ - ]

Purpose - To search the effects of montelukast on the airway inflammation including FEV1%, FEV1%/FVC, the provocholine® (methacoline chloride powder for inhalation) challenge tests, the leukotriene levels in the exhaled breath condensate in asthmatic children with and without food allergy aged 6-18 years old. - To define the patient groups with good response to montelukast and to define the parameters which predict the good response.

Current Primary Outcome Measuresthe difference in FEV1% between two arms. [Time Frame: 10 weeks] [Designated as safety issue: Yes]The asthmatic children with and without food allergy will be given placebo and montelukast following one another in a cross over design. The study will be performed in 2 groups of patients (Patients with and without food allergy) parallel to each other at the same time and within each group the patients will take montelukast and placebo. A total of 5 spirometry tests (At the beginning and end of run-in periods, at the beginning of cross-over period, at the end of wash-out period and at the end of the study) will be done and forced expiratory volume in one second (FEV1) will be evaluated.
Current Secondary Outcome Measures
  • Exhaled breath condensate [Time Frame: 14 weeks] [Designated as safety issue: No]It will be collected 4 times during the study period (At the beginning and at the end of drug and placebo usage periods.)Cysteinyl leukotrienes, Prostaglandin D2, lipoxin levels will be measured in the exhaled breathe condensate
  • Fractional exhaled Nitric Oxide [Time Frame: 14 weeks] [Designated as safety issue: No]It's measurement will be done 4 times during the study period (At the beginning and at the end of drug and placebo usage periods.) (See flow chart).
  • asthma control test [Time Frame: 14 weeks] [Designated as safety issue: No]
  • bronchial hyperreactivity [Time Frame: 14 weeks] [Designated as safety issue: No]In order to document the level of bronchial hyperreactivity of the patients, the provocholine (methacholine chloride powder for inhalation) provocation tests will be performed 4 times (At the beginning and at the end of drug and placebo usage periods)

Brief TitleEffects of Montelukast in Asthmatic Children With and Without Food Allergy
Official TitlePhase 4 Study of Effects of Montelukast Treatment on Allergic Inflammation in Children With and Without Food Allergy, Single Centered, Randomised, Double Blind, Placebo Controlled Parallel Group Cross-over Study
Brief Summary
- To search the effects of montelukast on the airway inflammation including FEV1%,
FEV1%/FVC, the provocholine® (methacoline chloride powder for inhalation) challenge
tests, the leukotriene levels in the exhaled breath condensate in asthmatic children
with and without food allergy aged 6-18 years old.

- To define the patient groups with good response to montelukast and to define the
parameters which predict the good response.
Detailed Description
The aim of this analysis is to determine whether the children with food allergy may have
more eosinophilic inflammation in the airways (as measured by FENO) or they may have
Cysteinyl leukotrienes based inflammation in the airways that will be shown by high levels
of Cys LT and low levels of lipoxin in the exhaled breath condensate. Our suggestion is that
a special pattern of inflammation may be seen in asthmatics with food allergy because of
their strong atopic march history and then we aimed to test if montelukast is more effective
in children when the ratio of Cysteinyl LT inflammation is high relative to FENO
(eosinophilic inflammation). This study will be the first to evaluate the effect of
montelukast regarding the synthesis of Cys leukotrienes, lipoxin and FENO that will be
measured from exhaled breath condensate, which is the mirror of the local inflammation in
the airways in asthmatic children with atopy (food allergy). As we mentioned above another
factor that we are planning to analyze is the ratio of Cys leukotriene to lipoxin, which is
the natural antagonist of LT. This study will determine the ratio of Cyst LT to lipoxin and
Cyst LT to FENO in the exhaled breath condensate and then there will be an analysis to see
the correlation of these inflammatory markers with montelukast related changes on FEV1%,
FEV1%/FVC.

InterventionDrug: Montelukast
Placebo and montelukast (5 mg for 6-14 years of age and 10 mg for 14-18 years of age once a day) will be given following one another in 4 weeks periods including a 2 weeks wash-out period in between in a cross over design.

    The study will be performed in 2 groups of patients (Patients with and without food allergy) parallel to each other at the same time and within each group the patients will take montelukast and placebo (one after another in a double-blind design).
  • Active Comparator: asthma without food allergy
    The study will be performed in 2 groups of patients (Patients with and without food allergy) parallel to each other at the same time and within each group the patients will take montelukast and placebo (one after another in a double-blind design)
