The researcher proposes to assess levels of sputum inflammatory markers (eosinophils, eosinophil cationic protein (ECP), neutrophils IL-8) before and while on anti-IgE therapy in a pediatric population of moderate to severe asthmatics who have ongoing persistent asthma symptoms despite on moderate to high doses of inhaled corticosteroids (ICS).

Associations will be assessed between the types of sputum inflammatory markers and the patient's atopic status and level of asthma control as indicated by the following measures:

  1. pulmonary function test (PFT)
  2. asthma symptoms based on the Asthma Control Test (ACT)

Condition Intervention Phase
Allergic Asthma Drug: ANTI-IGE THERAPY (XOLAIR) Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)

Primary Outcome Measures:
  • description of sputum inflammatory markers

Secondary Outcome Measures:
  • improvement in lung functions and symptoms scores

Estimated Enrollment: 40
Study Start Date: January 2006
Study Completion Date: January 2009
Primary Completion Date: January 2009 (Final data collection date for primary outcome measure)
Detailed Description:


Primary: Describe inflammatory cell types in study patients and compare changes in inflammatory cell patterns before and during anti-IgE therapy.

Secondary:Describe patterns of sputum eosinophilia and neutrophilia in relation to asthma symptom improvement based on ACT and PFT


Differences in inflammatory response after the addition of anti-IgE therapy can be described in neutrophilic, eosinophilic and neutrophilic/eosinophilic asthmatics.

Neutrophilic asthmatics patients will fail to respond when placed on anti-IgE while eosinophilic asthmatics will respond well.

Sputum inflammatory markers are sensitive markers of inflammation and can predict response to new asthma treatment modalities such as anti-IgE therapy.
