These altered responses are the reason they demonstrate steroid resistance.', 'detailedDescription': 'Current NHLBI guidelines for persistent asthma management recommends the use of steroids for treatment of airway inflammation (1,2). However, some asthmatics do not respond to steroids (3-6). Unfortunately these patients are subjected to the unwanted side effects (osteoporosis, cataracts, etc) of high dose steroid therapy because non-immune tissues remain sensitive to steroids. Recent studies suggest that the costs of asthma are largely attributable to uncontrolled disease (7). Thus, it is important to understand the mechanism(s) of steroid resistance and introduce new forms of therapy for the treatment of these difficult to control asthmatics. As a prelude to pharmaceutical studies in steroid resistant asthma, it is imperative to develop biomarkers that can robustly identify individuals likely to be poor steroid responders so that alternative non-steroid anti-inflammatory therapies, such as Xolair®, can be introduced early in the course of asthma therapy.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '12 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
