Comparison to the recent Stankovic et al. study [11], involving a patient population similar to ours and using more anatomically matched normal control tissue (i.e. 7 ethmoid sinus specimens of the 10 nasosinus control specimens), provided confidence because differential expression of several genes important in aspirin-sensitive aCRSwNP were also identified in our data (decreased AZGP1, STATH, and PIP and increased DC-SIGN (CD209) and POSTN; with increased POSTN expression also being observed in eosinophilic esophagitis (EE) [18]). This evidence concerns the gene AZGP1 and eosinophilic esophagitis.
