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.
