概括
与标准血液透析相比,高剂量在线血液透析显著降低了功能衰竭患者的死亡风险. 这种益处取决于剂量,并且在不同患者小组中一致,这表明血液过是一种优越的治疗选择.
科学领域:
- 肝脏病学
- 临床试验
- 综合分析
背景情况:
- 高剂量血液过 (HDF) 显示,与高流量血液过 (HD) 相比,功能衰竭患者的死亡率减少了23%.
- 关于HDF与HD的子组效应,剂量反应关系和因果特异性死亡率存在不确定性.
研究的目的:
- 为了比较HDF和HD对所有原因和特定原因死亡率的影响.
- 调查不同患者小组治疗效果的潜在差异.
- 检查对流量和死亡风险之间的剂量反应关系.
主要方法:
- 随机对照试验的个体患者数据元分析,比较在线HDF和HD.
- 搜索了MEDLINE,Embase和Cochrane的受控试验中心注册.
- 主要结果:全因死亡率. 使用考克斯比例危险回归分析. 进行了亚组和剂量反应分析.
主要成果:
- 包括5项试验,包括4153名患者;2083名患者接受了HDF,2070名患者接受了HD.
- 随访时间中位数为30个月. 所有原因的死亡率: 23. 3% (HDF) 和 27. 0% (HD) (HR 0. 84; 95% CI 0. 74- 0. 95).
- 没有发现显著的分组差异. 随着对流量增加,死亡风险降低 (剂量依赖效应).
结论:
- 与HD相比,在线HDF降低了功能衰竭患者的全因死亡率.
- 治疗效果与患者和治疗特征一致.
- HDF的死亡风险降低是剂量依赖的,支持其作为标准HD的优越替代品的考虑.

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Heart Failure Drugs: Diuretics
345
Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Renal Failure: Dose Adjustments
67
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.

Factors Affecting Renal Clearance: Renal Impairment
57
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 Drug Excretion: Glomerular Filtration
176
The kidney serves as the primary organ responsible for eliminating drugs and their metabolites from the body. This process, known as renal elimination, starts with glomerular filtration and results in urine formation. Each kidney houses millions of functional units called nephrons, where urine production occurs. A nephron has two main components: a renal corpuscle and a renal tubule.
Drugs gain access to the kidney via the renal artery, which progressively branches off into afferent arterioles....
