摘要

目的 探究血清3-氧酸辅酶A转移酶1(OXCT1)、含Xin肌动蛋白结合重复序列2(XIRP2)与特应性皮炎患儿病情程度、预后的关系。 方法 选取广东省中医院皮肤科门诊治疗的30例中重度特应性皮炎患儿为观察组,根据病情程度分为中度组(n = 15)和重度组(n = 15);根据治疗12周后预后情况分为预后良好组(n = 20)和预后不良组(n = 10)。同时,选取既往无过敏性疾病病史的30例健康儿童为对照组。采用数据非依赖性质谱法测定受试患儿血清蛋白质组水平,得到OXCT1、XIRP2水平;收集特应性皮炎患儿临床资料和IgE、嗜酸性粒细胞水平。对于特应性皮炎患儿预后不良的影响因素,采用logistic回归分析进行识别与验证;针对血清OXCT1、XIRP2对患儿不良预后的预测作用,通过ROC曲线分析予以评价,分析两者单独及联合预测的临床价值。 结果 观察组血清OXCT1水平与对照组相比显著升高、XIRP2水平显著降低(P 0.05);血清OXCT1水平随着特应性皮炎患儿病情的加重而逐渐升高,XIRP2水平随着特应性皮炎患儿病情的加重而逐渐降低(P 0.05);与预后良好组相比,预后不良组临床资料及IgE、嗜酸性粒细胞差异无统计学意义(P 0.05);血清XIRP2为特应性皮炎患儿预后不良的独立危险因素,而血清OXCT1为预后良好的保护因素(P 0.05);血清OXCT1、XIRP2、二者联合预测特应性皮炎患儿发生预后不良的AUC分别为0.940、0.885、0.945,二者联合预测的AUC高于各指标单独预测的AUC。 结论 特应性皮炎患儿血清OXCT1水平明显升高,而XIRP2水平明显降低,二者可能在疾病发生发展及预后转归过程中发挥不同阶段的生物学作用。其中OXCT1为预后良好的保护因素,而XIRP2为预后不良的危险因素,二者联合对特应性皮炎患儿预后具有较好的预测效能。

Abstract

Objective To explore the relationship between serum 3-oxoacid CoA-transferase 1 (OXCT1), Xin actin-binding repeat-containing protein 2 (XIRP2), and the severity and prognosis of atopic dermatitis (AD) in children. Methods Thirty children with moderate-to-severe AD who were treated at the Dermatology Outpatient Department of Guangdong Provincial Hospital of Chinese Medicine were enrolled in the observation group. According to the severity of their conditions, they were divided into a moderate group (n = 15) and a severe group (n = 15). After 12 weeks of treatment, they were further classified into a good prognosis group (n = 20) and a poor prognosis group (n = 10). Meanwhile, 30 healthy children with no previous history of allergic diseases were selected as the control group. Serum proteomic levels were measured by data-independent acquisition mass spectrometry (DIA-MS) to determine the expression levels of OXCT1 and XIRP2. Clinical data, immunoglobulin E (IgE) levels, and eosinophil counts of the AD children were collected. Logistic regression analysis was used to identify the factors influencing the poor prognosis in children with AD. Receiver operating characteristic (ROC) curve analysis was carried out to evaluate the value of serum OXCT1 and XIRP2, either individually or in combination. Results When compared with the control group, the serum OXCT1 level in the observation group showed a significant increase, and the XIRP2 level presented a significant decrease (P 0.05). Serum OXCT1 levels gradually rose as the disease severity worsened, while serum XIRP2 levels gradually declined (P 0.05). In comparison with the good prognosis group, there were no statistically significant differences in clinical data, IgE levels, or eosinophil counts in the poor prognosis groups (P 0.05). Serum XIRP2 was identified as an independent risk factor for poor prognosis in children with AD, whereas serum OXCT1 was identified as an independent protective factor (P 0.05). The area under the ROC curve (AUC) for poor prognosis was 0.940 for OXCT1, 0.885 for XIRP2, and 0.945 for the combination of both markers. The combined prediction AUC remained higher than that of either marker alone. Conclusions Serum OXCT1 levels were significantly elevated, and XIRP2 levels were significantly decreased in children with atopic dermatitis. These two factors may play biological roles at different stages of disease development and prognosis. OXCT1 functions as a protective factor, whereas XIRP2 serves as a risk factor for poor prognosis. The combined assessment of serum OXCT1 and XIRP2 shows good predictive efficacy for the prognosis of children with atopic dermatitis.
