Sinus Surgery Is Associated with a Decrease in Aspirin-Induced Reaction Severity in Patients with Aspirin Exacerbated...

Area of Science:

• Otolaryngology
• Allergy and Immunology
• Respiratory Medicine

Background:

• Nasal polyps contribute to eicosanoid production in Aspirin-Exacerbated Respiratory Disease (AERD).
• AERD diagnosis relies on graded aspirin challenges.
• The impact of sinus surgery on aspirin challenge outcomes in AERD is unknown.

Purpose of the Study:

• To evaluate how endoscopic sinus surgery (ESS) affects the severity of aspirin-induced reactions.
• To determine the influence of ESS on eicosanoid levels related to aspirin hypersensitivity.

Main Methods:

• Twenty-eight AERD patients underwent aspirin challenges before and 3-4 weeks after ESS.
• Respiratory parameters were monitored.
• Plasma and urine eicosanoid levels were measured before and after aspirin challenges.

Main Results:

• Post-ESS, all patients showed reduced aspirin reaction severity, with 43% having no detectable reaction.
• Lack of reaction correlated with lower eosinophilia, urinary leukotriene E4, and a lower plasma PGD2/PGE2 ratio.
• Significant differences (P < .05) were observed in these markers between reacting and non-reacting patients post-surgery.

Conclusions:

• ESS decreases aspirin sensitivity and reduces key eicosanoid levels in AERD patients.
• Aspirin challenges for suspected AERD should precede ESS to ensure diagnostic accuracy.
• Aspirin desensitization may be more effective after ESS due to lessened hypersensitivity.
