概括

时间加权平均蛋白尿 (TWAP) 预测IgA脏病 (IgAN) 的功能下降. 保持TWAP低于0.3g/g可能会减缓Igan的进展,强调蛋白尿控制的重要性.

科学领域:

腎臟病學 (nephrology) 是一種醫學專業.
免疫学免疫学免疫学

背景情况:

IgA脏病 (IgAN) 是全球质核突炎的主要原因,通常进展到末期脏疾病.
蛋白尿是Igan功能下降的关键指标,但最佳的长期评估方法仍在争论中.

研究的目的:

调查时间加权平均蛋白尿 (TWAP) 与IgA脏病患者功能下降之间的关联.
评估TWAP作为IGAN中的累积蛋白尿暴露的新型指标.

主要方法:

在2011-2023年间,对549名经活检确认的Igan患者进行了回顾性队列研究.
从蛋白质-肌氨酸比率计算的TWAP是主要暴露;估计的淋巴细胞过率 (eGFR) 的变化是主要结局.
一般化添加剂混合模型分析了TWAP和eGFR轨迹之间的关联,调整了临床和组织学因素 (牛津分类MEST-C得分).

主要成果:

较高的TWAP水平与基线eGFR为15-60毫升/分钟/1.73m2.2的患者的加速eGFR下降相关.
与TWAP<0.3g/g相比,较高的TWAP水平 (0.3-0.5,0.5-1,≥1g/g) 与每年的eGFR下降显著增加有关.
在EGFR≥60mL/min/1.73m2的患者中,TWAP≥1g/g是加速EGFR下降的唯一显著预测因素.

结论:

在Igan中,TWAP是功能下降的显著预测因素,特别是在患有现有的功能障碍的患者中.
保持TWAP低于0.3g/g可能会显著减缓Igan疾病的进展.
这项研究强调了严格的蛋白尿管理在IGAN中的关键作用.

关键词:

Factors Affecting Renal Clearance: Renal Impairment

Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Renal Clearance

Renal Clearance

The glomerular filtration rate (GFR) is a critical marker of kidney function, reflecting the efficiency of filtration by the glomeruli. Renal clearance of specific substances, such as inulin or creatinine, is commonly used to measure GFR.
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...
