Abstract

Background: Previous studies have shown that macrophage migration inhibitory factor (MIF) is involved in the pathogenesis of asthma. This study aimed to investigate whether serum MIF reflects a therapeutic response in allergic asthma. Methods: We enrolled 30 asthmatic patients with mild-to-moderate exacerbations and 20 healthy controls, analyzing the parameter levels of serum MIF, serum total immunoglobulin E (tIgE), peripheral blood eosinophil percentage (EOS%), and fractional exhaled nitric oxide (FeNO). Lung function indices were used to identify disease severity and therapeutic response. Results: Our study showed that all measured parameters in patients were at higher levels than those of controls. After one week of treatment, most parameter levels decreased significantly except for serum tIgE. Furthermore, we found that serum MIF positively correlated with EOS% as well as FeNO, but negatively correlated with lung function indices. Receiver operator characteristic (ROC) curve analysis indicated that among the parameters, serum MIF exhibited a higher capacity to evaluate therapeutic response. The area under the curve (AUC) of MIF was 0.931, with a sensitivity of 0.967 and a specificity of 0.800. Conclusions: Our results suggested that serum MIF may serve as a potential biomarker for evaluating therapeutic response in allergic asthma with mild-to-moderate exacerbations.

Abstract

目的

探讨血清巨噬细胞移动抑制因子在过敏性哮喘治疗反应评估中的应用价值。

创新点

采用血清巨噬细胞移动抑制因子评估过敏性哮喘的治疗反应。

方法

我们纳入了过敏性哮喘轻中度急性发作患者30例, 并以20例健康人为对照, 分别检测和分析了治疗前后患者以及健康人的血清巨噬细胞移动抑制因子, 总免疫球蛋白E (总IgE), 外周血嗜酸性粒细胞百分数和呼出气一氧化氮等指标, 同时进行肺功能检查以监测患者的治疗反应。

结论

血清巨噬细胞移动抑制因子作为一种潜在的生物标志物, 可用于评估过敏性哮喘轻中度急性发作患者的治疗反应。
