Serum IgE levels and its clinical correlation with varying patterns of bronchial asthma and nasal allergy.

In a study of 847 cases of bronchial asthma and nasal allergy frequent association with raised serum IgE was noticed. Degree of atopy (as judged by skin allergy tests), age, sex and duration of disease tended to influence IgE levels in asthmatics. Both extrinsic and intrinsic varieties of asthma showed similar raised serum IgE levels. In subjects with nasal allergy alone, the values were considerably lower but still much higher than found in control patients.
