HO-1: a new marker for predicting postoperative recurrence of CRSwNP.

BACKGROUND

Chronic rhinosinusitis with polyps (CRSwNP) is a subtype of chronic rhinosinusitis and is highly prone to recurrence; therefore, it is urgent to find appropriate markers to predict recurrence of CRSwNP after surgery.

PURPOSE: We aim to investigate the expression of HO-1 in CRSwNP and assess its value of predicting postoperative recurrence of CRSwNP.

METHODS

We recruited 77 participants and collected clinical data of all. We use Immunohistochemical staining to determine the expression of HO-1 in tissues. We use Spearman correlation test to analyze the correlation between HO-1 positive cell count and clinical score, and ROC curve to assess the value of HO-1 positive cell count in predicting recurrence of CRSwNP.

RESULTS

HO-1 positive cells were macrophages and significantly increased in CRSwNP; HO-1 positive cell count was negatively correlated with preoperative SNOT-22 score; HO-1 can predict postoperative recurrence of CRSwNP, AUC = 0.80, p = 0.004.

CONCLUSION

HO-1 is a biochemical marker of CRSwNP and can predict postoperative recurrence of CRSwNP.
