Distinct eicosanoid patterns in severe recalcitrant nasal polyposis

This study investigated the levels of nasally secreted eicosanoids before and after NP surgery in patients with or without NP recurrence. It explored potential endotypes based on pre‐surgical eicosanoid levels. Patients with recurrent NPs had pronounced pre‐surgical levels of nasal 15(S)‐HETE, PGD2 and LTE4. From pre‐surgery to 12 months after, NP recurrence was associated with a significant decrease of 15(S)‐HETE and PGD2 relative to non‐recurrence. In contrast, levels of LTE4 decreased at six months but increased again at 12 months. Elevated nasal LTE4, 12 months post‐surgery, in NP recurrent subjects, suggests that postoperative LTE4 measurements may indicate rapid NP regrowth. A distinct nasal eicosanoid profile may be used to identify the most severe recalcitrant patients needing to be targeted for immunomodulatory therapies.
