BACKGROUND: Aspirin challenge and desensitization remains the criterion standard in diagnosis and treatment for patients with aspirin-exacerbated respiratory disease (AERD), but the protocols can be time and resource intensive.
OBJECTIVE: To provide evidence that oral aspirin challenge and desensitization can be safely performed in an outpatient setting in 1 day.
METHODS: Forty-four patients with a confirmed diagnosis of AERD, stable asthma, and baseline FEV1 value greater than or equal to 70% of predicted completed an oral aspirin challenge and desensitization protocol. The starting dose was 40.5 mg with escalating doses of aspirin (81, 162.5, 325 mg) at 90-minute intervals until symptoms were provoked. Desensitization was defined as tolerating a repeated administration of the provocative aspirin dose and at least 1 subsequent dose, bringing the total aspirin ingested during the in-clinic desensitization to 325 mg or more.
RESULTS: Ninety-three percent of patients completed the challenge and desensitization in 1 day, with an average protocol completion time of 9 hours and 29 minutes. Two patients (4.6%) chose to complete the protocol over 2 days. One patient (2.3%) was discontinued from the protocol because of ongoing abdominal discomfort and diarrhea. No patient required epinephrine, emergency department visit, or hospitalization.
CONCLUSIONS: Patients with AERD on a stable asthma regimen and with a baseline FEV1 value greater than or equal to 70% can be safely desensitized to aspirin using a 90-minute dose escalation protocol, starting at a dose of 40.5 mg, and defining desensitization as tolerance of the repeated provocation dose and at least 1 subsequent aspirin dose, bringing total cumulative daily dose to 325 mg or more. This protocol can routinely be completed in 1 day.
