Abstract

AbstractObjectiveChronic rhinosinusitis (CRS), a common disease in otorhinolaryngology, seriously affects the life quality of patients. The existing therapy has certain limitations, and it is very urgent to deeply explore the pathogenesis and classification of CRS. Microbiome and inflammation are considered the causes of CRS, but the precise roles and the associations between these two factors in the pathogenesis of CRS remain controversial.MethodsSecretions were collected from the middle nasal canal, maxillary sinus and ethmoid sinus in CRS patients, then subjected to 16 S rRNA gene sequencing to profile microbiota community. Operational Taxonomic Units clustering and species annotation were adopted to obtain species diversity, prevalence rate and average relative abundance. Comparisons were performed at the level of microbial species and genus between CRS and control using NMDS, Anosim and MetaStat analysis. Th1 cytokines and Th2 cytokines were detected by ELISA. Spearman analysis were adopted to probe into the correlation between Th cytokines and microbial species in CRS.ResultsThirty‐seven patients were enrolled, among them 22 with CRS and 15 were controls. The most abundant genera were Corynebacterium and Staphylococcus no matter in CRS patients or control. Corynebacterium propinquum was significant decreased in CRS patients no matter with nasal polyp or not. The abundances of Prevotella birria and Carnobacterium maltaromaticum were significantly different between CRSsNP and CRSwNP group. The levels of cytokines IL‐2, TNF‐α, IFN‐ɣ, IL‐4, IL‐6, IL‐10 were all increased in CRS patients. The cytokines levels were associated with specific microbial species in nasal tissue.ConclusionThe changes of species richness and complexity in nasal microbiome were obvious in CRS patients with nasal polyps or not. The different cytokines levels and microbiome between CRS patients without nasal polyps and patients with nasal polyps suggest heterogeneity in pathogenesis of chronic rhinosinusitis. Distinct microbiota and different cytokines were strongly linked in CRS.Level of EvidenceNA.
