Despite treatment progress, 30% of patients have poor outcomes, likely due to the disease's complexity and a lack of new treatment targets. The incidence is rising, but there's a lack of nationwide studies on its variations. This study addresses this through a multicentric survey to create a national database on chronic rhinitis, including epidemiological, clinical, and biological data. The goal is to understand chronic rhinitis's causes and risks, improve treatments, and develop preventive strategies. The study will survey 30,000 patients across China, using questionnaires and nasal exams, and preserve biological samples in a biobank for detailed analysis. This will lay the groundwork for understanding the disease's mechanisms, developing new diagnostics, and tailoring prevention and treatment approaches for different forms of chronic rhinitis.",[26],"Chronic Rhinitis","RECRUITING","2024-06-05",{"date":30,"type":31},"2024-06-10","ACTUAL",{"date":33,"type":31},"2024-04-27",{"date":35,"type":22},"2027-08-01",{"name":37,"class":38},"Zheng Liu ENT","OTHER",""]
