Effect of short-course glucocorticoid application on patients with chronic rhinosinusitis with nasal polyps
Abstract
Background: Local and systemic glucocorticoids are mainstay therapies for chronic rhinosinusitis. With respect to local glucocorticoids, nasal spray is used extensively, but some patients do not benefit from short-course treatment. Recently, some clinicians have focused on the effects of high-dose local glucocorticoids in chronic rhinosinusitis with nasal polyps (CRSwNP), such as treatment using nasal irrigation, transnasal nebulization, and nose-dripping therapy (nasal drop) with high-dose budesonide. However, there are little data comparing the effect of short-course high-dose local glucocorticoids with regular nasal spray and oral steroids in the treatment of preoperative CRSwNP patients. Furthermore, the appropriate use of different types of glucocorticoids in different endotypes of CRSwNP remains unclear. Methods: This randomized controlled clinical research study was performed at a single academic center. Patients who satisfied the criteria of chronic rhinosinusitis with bilateral nasal polyps were randomly assigned in a 1:1:1 ratio to receive oral methylprednisolone, 24 mg/d and budesonide nasal spray, 256 μg/d, or intranasal budesonide suspension, 1 mg/d and budesonide nasal spray, 256 μg/d, or budesonide nasal spray, 256 μg/d for one week. Symptoms, endoscopic scores, and tissue and blood inflammatory cells were recorded before and after the study. Adverse events were recorded by clinicians. Results: A total of 127 patients with CRSwNP underwent randomization. The total nasal symptoms scores (TNSS) decreased significantly in all groups compared to those at baseline. The assessment of the reduction in TNSS demonstrated that the change was significantly greater in the nasal drop group than in the nasal spray group (−7.47 vs −4.10, P = 0.032), and it was also greater in the oral steroid group than in the nasal spray group (−7.30 vs −4.10, P = 0.039). A similar trend also appeared in the reduction in Sinonasal-Outcome Test 22 (SNOT-22). After treatment, a significantly reduction in NP score was observed in the nasal drop group (−0.82) and oral steroid group (−0.85) compared with that in the nasal spray group (−0.10), and there was no significant difference between the nasal drop and oral steroid groups (P = 0.98). While calculating the percentage of patients who were sensitive to glucocorticoid treatment, there was 10.26% in the nasal spray group, 47.37% in the nasal drop group, and 52.50% in the oral steroid group that were sensitive to glucocorticoid treatment. The reduction in NP score was more significant in patients with eosinophilic CRSwNP in the nasal drop group and oral steroid group than in the nasal spray group. However, in patients with non-eosinophilic CRSwNP, the change in NP size was similar in the different treatment groups. Conclusion: Budesonide suspension nasal drop can significantly improve the quality of life and reduce the endoscopic score following short-course treatment, and the treatment effect of nasal drop was better than that of regular nasal spray. Budesonide nasal suspension can be used as a regular treatment for eosinophilic CRSwNP and can be an alternative choice for patients with a high percentage of tissue eosinophil infiltration who cannot use oral glucocorticoids.
