Aspirin desensitization in aspirin-sensitive asthma: failure to maintain a desensitized state during prolonged therapy.
A patient with a history of asthma induced by acetylsalicylic acid (ASA) was found to be ASA sensitive when orally challenged with ASA. She was successfully desensitized using incremental doses of ASA given orally and maintained on ASA or other nonsteroidal antiinflammatory (NSAI) agents for the treatment of arthritis. After 6 months of uninterrupted therapy the patient developed asthmatic symptoms that were related to ASA and NSAI drug therapy. Although desensitization may be achieved in patients with ASA-sensitive asthma, sensitivity may recur despite continuous therapy.
