数据说明

Conditions: Sinusitis, Chronic, Sinus Disease, Sinus Infection, Sinus Infection Chronic. Chronic rhinosinusitis (CRS) is a common inflammatory condition of the paranasal sinuses. CRS patients experience persistent facial pain/pressure, nasal discharge, nasal obstruction, and loss of smell. Initial treatment includes topical and systemic steroids and (often multiple rounds of) antibiotics; however, two thirds of patients remain symptomatic despite medical therapy and require endoscopic sinus surgery. Direct medical and indirect social costs of CRS are substantial, with 57% of patients reporting absenteeism and poor health and 28% experiencing associated anxiety and depression. These hard-to-treat patients are classified as recalcitrant CRS (rCRS), have limited treatment options available, and are the focus of this trial. CRS was thought to occur due to impaired sinus ventilation and drainage however new evidence suggests that sinus mucosal inflammation, driven in part by microbiota disruptions and pathogen carriage, is the etiological factor behind CRS. Type of inflammation varies and cannot be predicted based on clinical variables alone. Several studies show that the microbiome composition of CRS patients is less diverse compared to healthy subjects, suggesting that community-level disruptions, and not individual opportunistic pathogens, may contribute to persistent inflammation. The investigators will conduct a proof-of-principle, randomized, double-blind, placebo-controlled trial of 80 subjects to test whether a sinus power wash plus SNMT improves clinical outcomes in CRS patients within 45 days compared to a sinus power wash and sham SNMT. The investigators will investigate the safety profile of SNMT and determine if SNMT-related CRS symptom improvement lasts up to 6 months. Finally, the investigators will investigate how SNMT contributes to CRS recovery, by tracking changes in the sinus microbiota and inflammation pre- and post-treatment. Results from our pilot study shows that SNMT produced CRS symptom improvement in 75% of patients. SNMT therapy m
