Effect of Postoperative Specific Immunotherapy Combined with Nasal Irrigation on Chronic Rhinosinusitis with Allergic Rhinitis.

Patients with chronic rhinosinusitis (CRS) and allergic rhinitis (AR) (CRSwAR) have a more severe condition with a higher rate of recurrence after endoscopic sinus surgery (ESS). This study aimed to explore the effect of specific subcutaneous immunotherapy (SCIT) and nasal irrigation on CRSwAR after ESS. Sixty-four patients who were diagnosed as CRSwAR and received ESS were enrolled and divided into groups A, B, and C to receive different postoperative treatment strategies (conventional medication, medication with nasal irrigation, and medication with nasal irrigation and SCIT), and their prognosis was evaluated by scoring, electron microscopy, and inflammatory factors. One year after ESS, the recurrence rate of group C was significantly reduced; and the scoring from baseline was significantly different among the three groups, which of group C were the best. The epithelium arrangement, cilia morphology, and inflammation of nasal mucosa in each group were better than those in the preoperative state; and those in group C were the best. After one year, the expression levels of eosinophil cationic protein (ECP), interleukin (IL)-8, and IL-17 in group B were lower than those of group A; and the expression levels of ECP, IL-8, IL-25, IL-33, IL-17 in group C were lower than those in group A. SCIT combined with nasal irrigation can improve the patients' symptoms and quality of life, promote the epithelialization of the mucosa in the surgical cavity, regulate the local immune response of the nasal cavity; thus improve the prognosis of patients with ESS after 1 year.
