Abstract:Objective To investigate the correlations between the changes of tumor necrosis factor α (TNF-α), T cell immunoglobulin mucin-domain protein-1 (Tim-1), toll-like receptor 4(TLR4) and the severity of the disease in patients with allergic rhinitis (AR).Methods A total of 77 AR patients received in the First People’s Hospital of Nanyang City from October 2021 to October 2022 were selected as the study group, and 100 healthy subjects were selected as the control group during the same period. Theri serum TNF-α, Tim-1 and TLR4 levels were detected. Pearson correlation analysis was used to analyze the relationships between serum TNF-α, Tim-1, TLR4 levels and the severity of the disease. Multivariate logistic regression was used to analyze the risk factors affecting AR.Results Compared with the control group and mild and moderate AR patients in the study group, serum levels of TNF-α, Tim-1, TLR4 and score for allergic rhinitis (SFAR) in severe AR patients were higher (P<0.05). Serum levels of TNF-α, Tim-1 and TLR4 were positively correlated with SFAR scores (P<0.05). TNF-α, Tim-1 and TLR4 were the risk factors affecting the severity of AR (P<0.05).Conclusions The serum levels of TNF-α, Tim-1 and TLR4 in AR patients are increased with the development of the severity of the disease, and the changes of serum TNF-α, Tim-1 and TLR4 are positively correlated with SFAR scores. Meanwhile, the TNF-α, Tim-1 and TLR4 are the influencing factors for the severity of AR, and ban be used to evaluate the degree of AR in clinic.
