急性荨麻疹患者血清IgE、sIgE、IL-6及CRP水平表达及临床价值
Expression and Clinical Value of Serum IgE, sIgE, IL-6 and CRP Levels in Patients with Acute Urticaria
目的 探讨急性荨麻疹患者血清免疫球蛋白E(immunoglobulin E,IgE)、特异性免疫球蛋白E(specific immunoglobulin e,sIgE)、白细胞介素-6(interleukin-6,IL-6)、C反应蛋白(C-reactive protein,CRP)水平表达及临床价值。 方法 选取2023年3月至2024年3月驻马店市中心医院收治的120例急性荨麻疹患者资料行回顾性研究,并按1∶1比例选取同期体检健康者120例行病例对照研究,比较两组血清IgE、sIgE、IL-6、CRP水平的差异,通过ROC曲线分析血清IgE、sIgE、IL-6、CRP水平诊断急性荨麻疹的价值,以及IgE、sIgE、IL-6、CRP水平的相关性。 结果 相较于对照组,研究组吸入性过敏原总检测率、食入性过敏原总检测率更高(P < 0.05);研究组总IgE抗体、过敏原sIgE抗体、CRP、IL-6水平也更高(P < 0.05)。ROC曲线分析显示,血清IgE、sIgE、IL-6、CRP水平诊断急性荨麻疹的AUC分别为0.783、0.733、0.784、0.748;敏感度分别为0.492、0.508、0.492、0.500,特异度均为1.000。将上述因素纳入Logistic回归模型,通过回归系数(β值分别为0.028、2.167、0.681、0.257)统计分析得出联合数据(联合数据 = 0.028 × IgE + 2.167 × sIgE + 0.681 × IL-6 + 0.257 × CRP)。联合数据诊断急性荨麻疹的AUC为0.865,敏感度、特异度为0.850、0.883。Pearson 相关性显示,血清IgE、sIgE、IL-6、CRP水平均呈正相关(r = 0.494、0.568、0.576、0.461、0.403,P < 0.05)。 结论 急性荨麻疹患者血清存在多种过敏原,IgE、sIgE、IL-6、CRP水平表达可作为临床诊断急性荨麻疹的有效指标,且联合数据诊断价值更优。
Objective The aim of this study was to investigate the expression levels and clinical significance of serum immunoglobulin E (IgE), specific immunoglobulin E (sIgE), interleukin-6 (IL-6) and C-reactive protein (CRP) in patients with acute urticaria. Methods A retrospective study was conducted using the data of 120 patients with acute urticaria admitted to our hospital from March 2023 to March 2024, and 120 healthy individuals who underwent physical examinations during the same period were selected in a 1:1 ratio to serve as controls. The differences in serum IgE, sIgE, IL-6 and CRP levels between the two groups were compared. The ROC curve was used to analyze the value of serum IgE, sIgE, IL-6, and CRP levels in diagnosing acute urticaria, and the correlation between serum IgE, sIgE, IL-6, and CRP levels was analyzed. Results Compared to the control group, the total inhalation allergen detection rate and total ingestion allergen detection rate were higher in the study group (P < 0.05). Compared to the control group, the study group had higher levels of total IgE antibodies, allergen sIgE antibodies, CRP, and IL-6 (P < 0.05). ROC curve analysis showed that the AUC values for diagnosing acute urticaria were 0.783, 0.733, 0.784, and 0.748 for serum IgE, sIgE, IL-6, and CRP levels, respectively. The sensitivity values were 0.492, 0.508, 0.492, and 0.500, with corresponding specificity values of 1.000 for each. The above factors were incorporated into the logistic regression model, and the regression coefficients (β) were calculated. The joint data (joint data = 0.028 × IgE + 2.167 × sIgE + 0.681 × IL-6 + 0.257 × CRP) were obtained through statistical analysis, with the regression coefficients being 0.028 for IgE, 2.167 for sIgE, 0.681 for IL-6, and 0.257 for CRP, respectively. The AUC for combined data diagnosis of acute urticaria was 0.865, with sensitivity and specificity of 0.850 and 0.883. Pearson correlation showed that serum IgE, sIgE, IL-6, and CRP levels were all positively correlated (r = 0.494, 0.568, 0.576, 0.461, 0.403, P < 0.05). Conclusion There are multiple allergens in the serum allergen detection of patients with acute urticaria. The expression of IgE, sIgE, IL-6, and CRP levels can be used as effective indicators for clinical diagnosis of acute urticaria, and the combined data has better diagnostic value.
