Abstract

Background Aspirin desensitization followed by daily aspirin provides therapeutic benefits to patients with aspirin-exacerbated respiratory disease (AERD). It is not well understood how eicosanoid levels change during aspirin treatment. Objective To investigate associations between clinical outcomes of aspirin treatment and plasma eicosanoid levels in patients with AERD. Methods Thirty-nine patients with AERD were offered aspirin treatment (650 mg twice daily) for 4 weeks. Respiratory parameters and plasma levels of multiple eicosanoids were recorded at baseline and after 4 weeks of aspirin therapy using the Asthma Control Test and Rhinoconjunctivitis Quality of Life Questionnaire. Respiratory function was evaluated using the FEV1 and nasal inspiratory peak flow. Results After aspirin treatment, respiratory symptoms improved in 16 patients, worsened in 12 patients, and did not change in 4 patients. Seven patients were unable to complete the desensitization protocol. Patients with symptom improvement had higher baseline plasma 15-hydroxyeicosatetraenoic acid (15-HETE) levels than did patients with symptom worsening: 7006 pg/mL (interquartile range, 6056-8688 pg/mL) versus 4800 pg/mL (interquartile range, 4238-5575 pg/mL), P =.0005. Baseline 15-HETE plasma levels positively correlated with the change in Asthma Control Test score (r = 0.61; P =.001) and in FEV1 after 4 weeks of aspirin treatment (r = 0.49; P =.01). It inversely correlated with Rhinoconjunctivitis Quality of Life Questionnaire score (r = −0.58; P =.002). Black and Latino patients were more likely to have symptom worsening on aspirin or fail to complete the initial desensitization than white, non-Latino patients (P =.02). Conclusions In patients with AERD, low baseline 15-HETE plasma levels and black or Latino ethnicity are associated with worsening of respiratory symptoms during aspirin treatment.
