Abstract

OBJECTIVE:

To measure alterations in SPA1, A2, and D gene expression in various forms of inflammatory chronic rhinosinusitis (CRS).

STUDY DESIGN AND SETTING:

Sinus mucosal biopsies were performed in patients with allergic fungal rhinosinusitis (AFS), CRS with nasal polyposis, cystic fibrosis (CF), and controls. SP mRNA was measured with quantitative polymerase chain reaction.

RESULTS:

Patients with CF (n = 4) showed significantly increased SPA1 (82-fold), SPA2 (100-fold), and SPD (47-fold) mRNA (P < 0.05) when compared with controls (n = 5). Patients with CRS with nasal polyposis (n = 5) also demonstrated elevated SPA1 (27-fold), SPA2 (13-fold), and SPD (13-fold). Patients with AFS (n = 7) had increased SPA1 (5-fold), SPA2 (9-fold), and SPD (17-fold), but were not statistically significant.

CONCLUSION:

SPA1, A2, and D are upregulated in various forms of CRS, but are significantly elevated in cystic fibrosis CRS.

SIGNIFICANCE:

Understanding the role of SPs in CRS will help develop novel treatment approaches for sinonasal pathoses.
