METHODS: The relationship between lipid mediator markers linked to inflammation induction, such as phospholipase A2/cyclooxygenase-2 (PLA2/Cox-2), and the mitochondrial dysfunction marker anti-mitochondrial antibodies (AMA-M2), and anti-histone autoantibodies in the etiology of ASD was investigated in this study using combined receiver operating characteristic (ROC) curve analyses. This study also sought to identify the linear combination for a given set of markers that optimizes the partial area under ROC curves. This study included 40 age- and sex-matched controls and 40 ASD youngsters. The plasma of both groups was tested for PLA2/COX-2, AMA-M2, and anti-histone autoantibodies\' levels using ELISA kits. ROC curves and logistic regression models were used in the statistical analysis.
RESULTS: Using the integrated ROC curve analysis, a notable rise in the area under the curve was noticed. Additionally, the combined markers had markedly improved specificity and sensitivity.
CONCLUSIONS: The current study suggested that measuring the predictive value of selected biomarkers related to mitochondrial dysfunction, autoimmunity, and lipid metabolism in children with ASD using a ROC curve analysis could lead to a better understanding of the etiological mechanism of ASD as well as its relationship with metabolism.
方法:与炎症诱导相关的脂质介质标志物之间的关系,如磷脂酶A2/环氧合酶-2(PLA2/Cox-2),和线粒体功能障碍标记抗线粒体抗体(AMA-M2),在这项研究中,使用组合的受试者工作特征(ROC)曲线分析研究了ASD病因中的抗组蛋白自身抗体。该研究还试图鉴定一组给定标记的线性组合,其优化ROC曲线下的部分面积。这项研究包括40名年龄和性别匹配的对照和40名ASD青少年。使用ELISA试剂盒检测两组血浆的PLA2/COX-2、AMA-M2和抗组蛋白自身抗体水平。采用ROC曲线和logistic回归模型进行统计分析。
结果:使用综合ROC曲线分析,曲线下的面积显着上升。此外,联合标记物的特异性和敏感性明显提高.
结论:当前的研究表明,测量与线粒体功能障碍相关的选定生物标志物的预测价值,自身免疫,使用ROC曲线分析ASD儿童的脂质代谢可以更好地了解ASD的病因机制及其与代谢的关系。
