ObjectiveTo explore the abnormal expression of HORMA domain containing protein 1 (HORMAD1) in chronic rhinosinusitis (CRS) patients and its correlation with the expression of inflammatory factors.Study DesignObservational study. Place and Duration of the Study: Department of Otolaryngology Head and Neck Surgery, the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University, China, from August 2021 to October 2022.MethodologyEighty CRS patients and 80 healthy volunteers participated in this study according to the inclusion and exclusion criteria. The plasma samples of the patients were collected and the level of HORMAD1 was determined by RT-qPCR methods. Commercially available ELISA kits were used for the detection of the levels of cytokines, and the correlation between HORMAD1 expression and the level of cytokines was analysed.ResultsHORMAD1 expression was significantly increased in CRS patients as compared to the healthy subjects. Moreover, the results of ROC curve suggested AUC for HORMAD1 was 0.9442, 95% confidence interval, 0.9057 to 0.9827. IL-1β, TNF-α, IL-6 as well as IFN-γ were all markedly elevated in the CRS group. Positive correlations were found between HORMAD1 expression and the cytokines.ConclusionHORMAD1 may trigger an inflammatory response in CRS patients. The results of the current study could be beneficial for improving the therapeutic efficacy of CRS patients.Key WordsHORMAD1, Chronic rhinosinusitis, Expression, Inflammatory factors, DNA damage, Cytokines.
