概括
血交换 (PLEX) 没有减少ANCA相关血管炎 (AAV) 的死亡率或末期病 (ESKD). 然而,PLEX对患有严重功能障碍 (肌素>5.7 mg/dL) 的患者显示有好处.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 类风湿病学 类风湿病学
- 免疫学 免疫学 免疫学
背景情况:
- 与ANCA相关的血管炎 (AAV) 通常会影响脏,可能导致末期脏疾病 (ESKD).
- 血交换 (PLEX) 在治疗AAV中脏参与的有效性尚未得到充分证实.
研究的目的:
- 在患有ANCA相关血管炎 (AAV) 和功能障碍的患者中评估血交换 (PLEX) 的有效性.
- 确定PLEX是否影响AAV患者功能受损的全因死亡率或ESKD的复合结果.
主要方法:
- 追溯队列研究涉及163名AAV和血清肌氨酸≥1.5 mg/dL的患者.
- 接受PLEX和未接受PLEX的患者之间的结局比较.
- 分析主要结果 (所有原因死亡率或ESKD) 和二次结果,包括住院感染.
主要成果:
- 总的来说,PLEX与死亡率或ESKD复合结果的显著降低无关 (aHR1.04).
- 在基线肌素>5.7 mg/dL的患者中,PLEX与ESKD风险降低 (aHR 0.38) 和综合结局的边缘性降低 (HR 0.45,p=0.05) 有关.
- 接受PLEX治疗的患者在住院感染率显著增加 (aRR为4.66,p=0.001).
结论:
- 在中度功能障碍的ANCA相关血管炎患者中,血交换可能对结局没有整体益处.
- 对于某些患有严重功能障碍的AAV患者来说,PLEX可能是有益的,这需要进一步研究.
- 在AAV患者使用PLEX时,增加住院感染的风险是一个重要的考虑因素.

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Acute Kidney Injury I: Introduction
880
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy
281
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...
