Jiang RS, Chiang YF, Liang KL. Efficacy and Safety of Xylitol Nasal Irrigation after Functional Endoscopic Sinus Surgery: A Randomized Controlled Study. Biomedicines 2024; 12:1377. [PMID: 38927584 PMCID: PMC11202173 DOI: 10.3390/biomedicines12061377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2024] [Revised: 06/14/2024] [Accepted: 06/19/2024] [Indexed: 06/28/2024] Open
Abstract
Xylitol is considered a naturally occurring antibacterial agent. It is generally believed to enhance the body's own innate bactericidal mechanisms. It also provides anti-adhesive effects against both Streptococcus pneumoniae and Haemophilus influenza. This study was performed to evaluate the efficacy and safety of xylitol nasal irrigation in the postoperative care of functional endoscopic sinus surgery (FESS). Patients with chronic rhinosinusitis who received FESS were recruited and randomly assigned to two groups at one month post-surgery. Thirty-five patients in the xylitol group received 400 mL of 5% xylitol nasal irrigation daily for 2 months, while another 35 in the normal saline (NS) group received 400 mL of NS nasal irrigation daily for 2 months. Prior to FESS, as well as before and after nasal irrigation, sinonasal symptoms were assessed through the 22-item Sino-Nasal Outcome Test Questionnaire. The patients also underwent an endoscopic examination while undergoing nasal function tests, and a cytokine measurement of the nasal lavage and a bacterial culture from the middle meatus were performed. The safety of the nasal irrigation was assessed through any self-reported adverse events, the Eustachian Tube Dysfunction Patient Questionnaire and the eustachian tube function test. The endoscopic scores and olfactory threshold significantly decreased after xylitol irrigation when compared with those before irrigation. The prevalence of Staphylococcus aureus in the nasal secretions also decreased significantly after xylitol irrigation. The amounts of Interleukin-5 and Interleukin-17A were significantly increased in the nasal lavage after xylitol irrigation. No side effects, including those related to eustachian tube function, were seen after nasal irrigation in both groups. Our results showed that xylitol nasal irrigation was both beneficial and safe during the postoperative care of FESS.

The efficacy of steroid-eluting stents on the local inflammation of chronic rhinosinusitis with nasal polyposis after endoscopic sinus surgery: a multicenter prospective longitudinal study. Eur Arch Otorhinolaryngol 2023; 280:5417-5431. [PMID: 37665343 DOI: 10.1007/s00405-023-08158-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 07/25/2023] [Indexed: 09/05/2023]
Abstract
PURPOSE Attenuating local inflammation of chronic rhinosinusitis with nasal polyps (CRSwNP) after endoscopic sinus surgery (ESS) was crucial. Corticosteroids were generally exploited to ameliorate the postoperative state of CRSwNP. This study aims to verify the efficacy of steroid-eluting stents on the local inflammation of CRSwNP following ESS. METHODS 57 CRSwNP were enrolled from September 2021 to April 2022. 30 were with stents, and 27 were without stents after ESS. Eosinophilic cationic protein (ECP), myeloperoxidase (MPO), eosinophil, and neutrophil levels in nasal secretions, as well as visual analog scale (VAS) and modified perioperative sinus endoscopy (POSE) scores, were assessed preoperatively and after 2, 4, 8, and 12 weeks. RESULTS All subjects of CRSwNP exhibited reduced results of eosinophil levels, neutrophil levels, nasal obstruction, nasal discharge, loss of smell, and total VAS scores after 12 weeks compared to the preoperative ones (p < 0.05). Compared with control subjects, CRSwNP with stents acquired lower levels of ECP, MPO, loss of smell, total VAS, and POSE scores at four follow-up visits, as well as reduced eosinophil and neutrophil levels in nasal secretions after 12 weeks (p < 0.05). Correlation analysis revealed that postoperative ECP and MPO levels of CRSwNP in nasal secretions correlated strongly with eosinophil and neutrophil levels, respectively, as well as POSE scores (r > 0.6). CONCLUSION These findings indicated that steroid-eluting stents might be an acclaimed option for CRSwNP in alleviating local inflammation to acquire a superior state after ESS.

Abstract
Chronic rhinosinusitis (CRS) is a highly heterogeneous disease characterized by inflammation in the nasal and sinus mucosa. The CRS phenotypes, based on the presence or absence of nasal polyps, are known as CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). However, this classification has limitations in fully capturing the mechanisms and clinical manifestations of CRS. To address the heterogeneity of CRS, there has been a growing focus on classifying the condition into distinct endotypes. Endotype classification involves grouping patients based on specific molecular, immunological, and clinical characteristics, allowing for more personalized and targeted treatment approaches.This review delves into the current state of endotype classifications for CRS. It explores the role of geographic factors, microbiome, and subphenotype in shaping different endotypes. Additionally, the review examines how various clinical features are associated with specific endotypes, providing valuable insights into tailoring treatment options for better outcomes and transitions between different endotypes.Overall, this review offers a comprehensive and up-to-date perspective on the intricate realm of CRS endotype classifications. By unraveling the molecular and clinical intricacies, this review lays the foundation for more precise, effective, and individualized treatment strategies in the management of CRS.
