Photo-inactivated allergens. II. Clinical experience with house dust allergen in pulmonary function tests and in immunotherapy.

Abstract

Purified house dust allergen irradiated with UV‐light loses its capacity to elicit immediate type skin and bronchial provocation reactions in the majority of asthmatic patients. However, in some patients both immediate and/or late bronchial reactions were observed to the active house dust and its inactivated counterpart.
