IgA nephropathy (IgAN) is a leading cause of chronic kidney disease (CKD), which are commonly accompanied by dyslipidemia. Obesity is also associated with dyslipidemia and risk of CKD, but the relation of the dyslipidemia patterns with obesity and disease progression in IgAN patients remains unknown. Traditional Chinese medicine (TCM) and the combined treatment with corticosteroids and TCM have been shown to be of benefit for IgAN patients, but predictive markers for guiding these treatments are lacking. Here, we quantified 545 lipid species in the plasma from 196 participants, including 140 IgAN patients and 56 healthy volunteers, and revealed an altered plasma lipidome in IgAN patients as compared to healthy participants. Association analysis showed that a subgroup of glycerides, particularly triacylglycerols (TGs) containing docosahexaenoic acid, were positively associated with high body mass index (BMI) in under- or normal-weight IgAN patients, while several free fatty acids and sphingomyelins were positively associated with high BMI in overweight or obese IgAN patients. Further, our study suggested that elevated levels of eight lipids, mainly TG species containing linolenic acid, were independent risk factors for IgAN progression and also reported the prospective association of circulating lipids with treatment outcomes in IgAN. Taken together, our findings may not only help to achieve precision medicine but also provide a knowledge base for dietary intervention in the treatment of IgAN.

脂质组学揭示了 IgA 肾病患者的循环脂质与体重指数和预后的关联

IgA 肾病 (IgAN) 是慢性肾脏病 (CKD) 的主要原因,CKD 通常伴有血脂异常。肥胖也与血脂异常和 CKD 风险相关,但 IgAN 患者血脂异常模式与肥胖和疾病进展的关系仍然未知。中医药 (TCM) 以及皮质类固醇和中药的联合治疗已被证明对 IgAN 患者有益,但缺乏指导这些治疗的预测标志物。在这里,我们量化了 196 名参与者(包括 140 名 IgAN 患者和 56 名健康志愿者)血浆中的 545 种脂质种类,并发现与健康参与者相比,IgAN 患者的血浆脂质组发生了改变。关联分析表明,甘油酯的一个亚组,特别是含有二十二碳六烯酸的甘油三酯(TGs)与体重不足或正常的 IgAN 患者的高体重指数(BMI)呈正相关,而一些游离脂肪酸和鞘磷脂与超重或肥胖的 IgAN 患者的高体重指数(BMI)呈正相关。此外,我们的研究表明,八种脂质(主要是含有亚麻酸的 TG 物种)水平升高是 IgAN 进展的独立危险因素,并且还报告了循环脂质与 IgAN 治疗结果的前瞻性关联。综上所述,我们的研究结果可能不仅有助于实现精准医疗,还可以为 IgAN 治疗中的饮食干预提供知识基础。而一些游离脂肪酸和鞘磷脂与超重或肥胖 IgAN 患者的高 BMI 呈正相关。此外,我们的研究表明,八种脂质(主要是含有亚麻酸的 TG 物种)水平升高是 IgAN 进展的独立危险因素,并且还报告了循环脂质与 IgAN 治疗结果的前瞻性关联。综上所述,我们的研究结果可能不仅有助于实现精准医疗,还可以为 IgAN 治疗中的饮食干预提供知识基础。而一些游离脂肪酸和鞘磷脂与超重或肥胖 IgAN 患者的高 BMI 呈正相关。此外,我们的研究表明,八种脂质(主要是含有亚麻酸的 TG 物种)水平升高是 IgAN 进展的独立危险因素,并且还报告了循环脂质与 IgAN 治疗结果的前瞻性关联。综上所述,我们的研究结果可能不仅有助于实现精准医疗,还可以为 IgAN 治疗中的饮食干预提供知识基础。是 IgAN 进展的独立危险因素,并且还报告了循环血脂与 IgAN 治疗结果的前瞻性关联。综上所述,我们的研究结果可能不仅有助于实现精准医疗,还可以为 IgAN 治疗中的饮食干预提供知识基础。是 IgAN 进展的独立危险因素,并且还报告了循环血脂与 IgAN 治疗结果的前瞻性关联。综上所述,我们的研究结果可能不仅有助于实现精准医疗,还可以为 IgAN 治疗中的饮食干预提供知识基础。
