AIMS/HYPOTHESIS Metabolic dysregulation may precede the onset of type 1 diabetes. However, these metabolic disturbances and their specific role in disease initiation remain poorly understood. In this study, we examined whether children who progress to type 1 diabetes have a circulatory polar metabolite profile distinct from that of children who later progress to islet autoimmunity but not type 1 diabetes and a matched control group. METHODS We analysed polar metabolites from 415 longitudinal plasma samples in a prospective cohort of children in three study groups: those who progressed to type 1 diabetes; those who seroconverted to one islet autoantibody but not to type 1 diabetes; and an antibody-negative control group. Metabolites were measured using two-dimensional GC high-speed time of flight MS. RESULTS In early infancy, progression to type 1 diabetes was associated with downregulated amino acids, sugar derivatives and fatty acids, including catabolites of microbial origin, compared with the control group. Methionine remained persistently upregulated in those progressing to type 1 diabetes compared with the control group and those who seroconverted to one islet autoantibody. The appearance of islet autoantibodies was associated with decreased glutamic and aspartic acids. CONCLUSIONS/INTERPRETATION Our findings suggest that children who progress to type 1 diabetes have a unique metabolic profile, which is, however, altered with the appearance of islet autoantibodies. Our findings may assist with early prediction of the disease.

循环代谢产物发展为胰岛自身免疫和1型糖尿病。

目的/假设代谢异常可能在1型糖尿病发作之前。然而,这些代谢紊乱及其在疾病引发中的特定作用仍知之甚少。在这项研究中,我们检查了进展为1型糖尿病的儿童的循环极性代谢产物谱与后来进展为胰岛自身免疫但不是1型糖尿病的儿童和配对对照组是否具有不同的循环极性代谢产物。方法我们在三个研究组的前瞻性儿童队列中分析了415个纵向血浆样品中的极性代谢物:那些进展为1型糖尿病的儿童;血清转化为一种胰岛自身抗体但未转化为1型糖尿病的患者;和抗体阴性对照组。使用二维GC高速飞行时间MS测量代谢物。结果在婴儿期,与对照组相比,进展为1型糖尿病与氨基酸,糖衍生物和脂肪酸(包括微生物来源的分解代谢产物)下调有关。与对照组和血清转化为一种胰岛自身抗体的患者相比,在进展为1型糖尿病的患者中,蛋氨酸仍然持续上调。胰岛自身抗体的出现与谷氨酸和天冬氨酸的减少有关。结论/解释我们的研究结果表明,进展为1型糖尿病的儿童具有独特的代谢特征,但是随着胰岛自身抗体的出现而改变。我们的发现可能有助于疾病的早期预测。与对照组相比。与对照组和血清转化为一种胰岛自身抗体的患者相比,在进展为1型糖尿病的患者中,蛋氨酸仍然持续上调。胰岛自身抗体的出现与谷氨酸和天冬氨酸的减少有关。结论/解释我们的研究结果表明,进展为1型糖尿病的儿童具有独特的代谢特征,但是随着胰岛自身抗体的出现而改变。我们的发现可能有助于疾病的早期预测。与对照组相比。与对照组和血清转化为一种胰岛自身抗体的患者相比,在进展为1型糖尿病的患者中,蛋氨酸仍然持续上调。胰岛自身抗体的出现与谷氨酸和天冬氨酸的减少有关。结论/解释我们的研究结果表明,进展为1型糖尿病的儿童具有独特的代谢特征,但是随着胰岛自身抗体的出现而改变。我们的发现可能有助于疾病的早期预测。胰岛自身抗体的出现与谷氨酸和天冬氨酸的减少有关。结论/解释我们的研究结果表明,进展为1型糖尿病的儿童具有独特的代谢特征,但是随着胰岛自身抗体的出现而改变。我们的发现可能有助于疾病的早期预测。胰岛自身抗体的出现与谷氨酸和天冬氨酸的减少有关。结论/解释我们的研究结果表明,进展为1型糖尿病的儿童具有独特的代谢特征,但是随着胰岛自身抗体的出现而改变。我们的发现可能有助于疾病的早期预测。
