Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Nasal microorganisms, exfoliated cells, nasal secretions, fetal microorganisms and blood were collected from patients with chronic sinusitis with nasal polyps before medication. Nasal polyp tissues of the patients were clamped for pathologic biopsy in the outpatient clinic. Methylprednisolone was then administered to the patients for 17 days, and the nasal microbial changes were observed after the administration of the drug. Patients underwent surgical treatment after the administration of the drug, and postoperative patients were followed up for a long period of time until polyp recurrence. During the follow-up, the microorganisms in the patients' postoperative nasal cavities were collected and the postoperative microbial changes were recorded

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study, we retrospectively collected pathologic paraffin specimens and patient information from previous cases of sinusitis with nasal polyps, and prospectively collected specimens from newly enrolled patients with nasal polyps.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

\- The diagnosis of CRSwNP was based on EPOS20201 ECRSwNP was defined as EO accounting for more than 27% of the total infiltration Subjects undergoing septoplasty due to anatomical variations served as controls Discontinuation of steroid (oral or aerosol) and antileukotriene therapy for at least 4 weeks prior to biopsy or surgery

Exclusion Criteria

\- Exclude patients with a diagnosis of posterior maxillary sinus polyps, cystic fibrosis, allergic fungal sinusitis, primary ciliary dyskinesia, allergic rhinitis, immune deficiency, or coagulopathy Exclusion of patients with aspirin intolerance (AERD) Exclude smokers Exclude pregnant women

Healthy Volunteers:

Only patients with deviated septum without any other nasal diseases served as a control group, and the participants in this group were not treated with corticosteroids and went in for septal correction. The rest of the criteria were the same
