乙酰唑胺疗法与非白蛋白尿 1 型糖尿病患者的肾功能。
背景:钠-葡萄糖共转运体-2抑制剂(SGLT2i)可降低2型糖尿病患者肾衰竭的风险。据推测,其作用机制是通过向远端肾小管输送更多的钠,激活肾小管-肾小球反馈,从而降低肾小球滤过率(GFR)和肾小球内压。由于存在糖尿病酮症酸中毒的风险,SGLT2is 未被批准用于 1 型糖尿病患者。乙酰唑胺是一种近端肾小管利尿剂,可向远端肾小球输送更多的钠,并可能以类似于 SGLT2is 的方式激活肾小管-肾小球反馈,但不会增加糖尿病酮症酸中毒的风险。有关乙酰唑胺对 1 型糖尿病患者肾脏的影响和安全性的研究尚不充分:我们进行了一项剂量递增试验,以确定 12 名 1 型糖尿病患者口服 3 种剂量乙酰唑胺(62.5 毫克、125 毫克和 250 毫克,均为每日两次)的效果。参与者接受 2 周的治疗,然后经过 2 周的冲洗后再接受下一剂量水平的治疗。在每个治疗间隔前后,都会对血液和尿液的化学成分以及碘海醇测量的肾小球滤过率进行评估。我们的目标是找出一个剂量,既能最大限度地降低测得的 GFR 降低率,又能最大限度地减少不良反应:平均年龄为 46±17 岁,100% 为白人,75% 为女性。基线测量的平均 GFR 为 89±18ml/min/1.73m2。服用乙酰唑胺 62.5 毫克、125 毫克和 250 毫克,每天两次,2 周后测得的 GFR 分别降低 15%(95% CI 9,21)、14%(95% CI 7,21)和 15%(95% CI 10,21)。所测得的肾小球滤过率下降在每两周的冲洗后完全逆转。随着剂量的增加,血清碳酸氢盐分别降低了 2.3、4.2 和 4.4 mEq/L,但未观察到低钾血症(< 3.5 mEq/L)的发生:结论:在肾功能保持良好的 1 型糖尿病患者中,乙酰唑胺会导致测量到的 GFR 急性、可逆性下降,但不会影响糖代谢。

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.
