Asthma and urticaria during disodium cromoglycate treatment. A case report.
A 10-year-old asthmatic boy began to suffer from urticarial rash and moderately severe bronchospasm after 8 weeks' treatment with disodium cromoglycate. Initially, DSCG had helped to control his asthmatic attacks, and steroid therapy could be discontinued. Inhalation provocation test with DSCG aerosol, 4 months after stopping DSCG treatment, showed an immediate-type 1 response and urticaria. A repeat provocation test, under antihistaminic cover , failed to produce similar response. When DSCG was withdrawn, urticaria vanished and the child remained symptom-free. Disodium cromoglycate is regarded as the possible aetiological agent.
