Selection Criteria for Inclusion in the Evaluation Study
[0051]Testing of the usefulness of anti-IgE for the treatment of COPD was carried on 143 patients with symptoms requiring ongoing management. For each patient, age, sex, smoking history, and family history (1st degree relatives) of allergic or obstructive disease were recorded. Serum IgE was measured in International Units (IU). Serum eosinophil levels were measured in most cases. Atopy was evaluated with skin test reactivity to a panel of 24 relevant inhalant antigens according to guidelines of the American Academy of Allergy, and was scored on a severity scale of 0 to 3 (3=prick test reactivity with wheal>2 mm; 2=prick test reactivity with wheal<2 mm; 1=negative prick test reactivity with intradermal reactivity only; 0=no reactivity). The individual skin test scores were added to obtain a total skin test score. Pulmonary function tests (PFT) were performed on a Collins G.S. Spirometer according to American Thoracic Society gu...

Evaluation Study
Omalizumab Treatment Group
[0058]Of the 88 patients in with an IgE>30 IU, 17 were entered into the study (Table 2) on the basis of disease severity in the one year baseline period prior to treatment—16 patients had experienced a total of 60 acute exacerbations that resulted in 20 hospitalizations and 40 outpatient emergency room / doctor visits, while 1 patient was O2 and steroid dependant with 3 prior intubations (four patients, overall, were O2 dependant). They had severe obstructive disease—8 patients had an FEV1 of less than 50% predicted. There was minimal reversibility—5 patients of the 16 had reversibility>15%. The COPD severity score ranged from 11 to 28. Eight patients had positive skin tests to both indoor and outdoor allergens, 6 patients were positive to indoor allergens alone, and 2 patients were negative to skin testing as well as to RAST testing (Table 3).
