摘要

背景:缺铁在肾衰竭儿童中很常见,但目前的指南是基于可能受炎症影响的铁储存生物标志物。这是第一项在接受骨活检的肾衰竭人群中检测血清铁指数与可染色骨髓铁储存(金标准)相关性的研究:这项横断面研究共纳入了 71 名临床病情稳定、接受透析治疗的儿童和年轻成人,他们在 2007 年至 2011 年期间因慢性肾病-矿物质骨骼紊乱而接受了骨活检。骨活检采用珀尔斯普鲁士蓝染色,由一名病理学家独立判读,该病理学家对参与者的铁参数和临床状态保持盲法。骨髓染色分为无染色和有染色,以便进行接收器运算曲线(ROC)分析。在 ROC 分析中,将血清铁蛋白检测可染色骨髓铁储存的能力与转铁蛋白饱和度 (TSAT)、血清血钙素、基于临床指南的血清铁、TSAT 及其组合的缺铁临界值进行了比较:平均年龄为 17.2 ± 4.4 岁(2-28 岁不等),30% 的患者为女性。透析年限中位数为 1.2 年(IQR 0.7-2.0 年),56% 的患者接受腹膜透析。平均血红蛋白为 12.4 ± 1.7 g/dl,35% 的患者在活组织检查时正在接受铁剂补充。根据骨髓铁储存耗尽的金标准,46.5%的患者缺铁。作为骨髓铁染色的指标,血清铁蛋白的ROC曲线下面积高于血清血钙素、TSAT或基于临床指南的TSAT+铁蛋白评估:在这组肾衰竭儿童和年轻成人中,血清铁蛋白是可染色骨髓铁储存的最佳指标,其次是转铁蛋白饱和度。

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.
