基于系统活检的转录组学与临床实践中抗体介导的肾移植排斥反应的诊断。
背景:为了诊断肾移植抗体介导的排斥反应,根据班夫分类法,基于活检的转录组学可以替代一些组织学标准。然而,这些检测方法在临床上的可及性仍然有限。在此,我们旨在评估在临床实践中整合常规兼容的分子检测方法对诊断抗体介导的排斥反应的影响:我们回顾性地纳入了本中心在 2013 年至 2017 年期间进行的所有活检。这些活检样本被分为三组:"抗体介导的排斥反应活检组织",这些活检组织完全符合班夫抗体介导的排斥反应标准,与基于活检的转录组学无关;"未确定为抗体介导的排斥反应",这些活检组织不符合抗体介导的排斥反应组织学标准,但如果基于活检的转录组学呈阳性,则会被视为抗体介导的排斥反应;以及对照活检组织,这些活检组织未显示排斥反应特征:在纳入期内,342 份活检样本获得了完整的 Banff 评分。其中 36 例活检样本已符合抗体介导的排斥反应标准,306 例活检样本中有 43 例(14%)被视为 "未确定抗体介导的排斥反应"。在这些活检样本中,43 例中有 24 例(56%)具有抗体介导的排斥反应分子特征,因此被重新归入 "抗体介导的排斥反应 "类别。这些活检样本的五年死亡剪除存活率较低,在统计学上与 "抗体介导的排斥反应 "类别的存活率相当(p = 0.22),24 例中有 15 例(63%)发生移植物丢失:结论:根据班夫分类法,基于活检的转录组学诊断抗体介导的排斥反应可使相当一部分活检受益。使用常规兼容的分子工具,这些活检样本中有一半以上被重新分类为抗体介导的排斥反应,并与异体移植物存活率低有关。

期刊介绍: The Clinical Journal of the American Society of Nephrology strives to establish itself as the foremost authority in communicating and influencing advances in clinical nephrology by (1) swiftly and effectively disseminating pivotal developments in clinical and translational research in nephrology, encompassing innovations in research methods and care delivery; (2) providing context for these advances in relation to future research directions and patient care; and (3) becoming a key voice on issues with potential implications for the clinical practice of nephrology, particularly within the United States. Original manuscript topics cover a range of areas, including Acid/Base and Electrolyte Disorders, Acute Kidney Injury and ICU Nephrology, Chronic Kidney Disease, Clinical Nephrology, Cystic Kidney Disease, Diabetes and the Kidney, Genetics, Geriatric and Palliative Nephrology, Glomerular and Tubulointerstitial Diseases, Hypertension, Maintenance Dialysis, Mineral Metabolism, Nephrolithiasis, and Transplantation.
