利用透皮检测方法测量肾小球滤过率。
背景:众所周知,目前在临床实践中使用的估计GFR (eGFR)的准确性存在局限性,这给肾功能下降或有肾功能下降风险的患者提供最佳护理带来了障碍。一种即时肾小球滤过率(GFR)测量方法有可能解决这些局限性。我们前瞻性地评估了新型GFR荧光示踪剂relmapirazin在Fitzpatrick皮肤量表(FSS)中所有人类皮肤颜色的肾功能正常或受损参与者中的透皮检测。方法:进行了一项多中心研究,包括74名eGFR从正常到4期CKD的参与者。FSS I-III型46例,IV-VI型28例。将一个包含LED和光电探测器的模块粘附在每个参与者的上胸部,以激活和收集经皮雷马吡嗪荧光。静脉推注雷马匹嗪(1.5mg/kg),观察12小时荧光发射情况。两室药代动力学模型拟合荧光强度-时间数据,并从第二(末端)室提取荧光清除率(FCR)。同时测量血浆雷马吡嗪浓度,并测定每位参与者相应的血浆GFR。采用线性回归分析比较FCR与指标血浆GFR。结果:参与者年龄在23 ~ 80岁之间,女性占59%。在荧光强度与时间数据中观察到两室药代动力学行为,并成功推断出完成12小时研究的每个参与者的FCR。FCR与指标血浆GFR在GFR测量范围内和所有肤色中产生了极好的相关性,r2 = 0.90(95%置信区间0.85至0.94)。无严重不良事件报告。结论:荧光GFR示踪剂雷马吡嗪的即时透皮检测在肾功能正常至受损的患者和一系列肤色类型中是可行的。

期刊介绍: The Journal of the American Society of Nephrology (JASN) stands as the preeminent kidney journal globally, offering an exceptional synthesis of cutting-edge basic research, clinical epidemiology, meta-analysis, and relevant editorial content. Representing a comprehensive resource, JASN encompasses clinical research, editorials distilling key findings, perspectives, and timely reviews. Editorials are skillfully crafted to elucidate the essential insights of the parent article, while JASN actively encourages the submission of Letters to the Editor discussing recently published articles. The reviews featured in JASN are consistently erudite and comprehensive, providing thorough coverage of respective fields. Since its inception in July 1990, JASN has been a monthly publication. JASN publishes original research reports and editorial content across a spectrum of basic and clinical science relevant to the broad discipline of nephrology. Topics covered include renal cell biology, developmental biology of the kidney, genetics of kidney disease, cell and transport physiology, hemodynamics and vascular regulation, mechanisms of blood pressure regulation, renal immunology, kidney pathology, pathophysiology of kidney diseases, nephrolithiasis, clinical nephrology (including dialysis and transplantation), and hypertension. Furthermore, articles addressing healthcare policy and care delivery issues relevant to nephrology are warmly welcomed.
