概括
非生物或生物人工肝支持系统 (NBAL/BAL) 对急性肝衰竭 (ALF) 或急性至慢性肝衰竭 (ACLF) 患者没有显著的生存益处. 对这些体外肝脏支持系统需要进一步的研究.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 关键护理医学 关键护理医学
- 生物医学工程 生物医学工程
背景情况:
- 急性肝衰竭 (ALF) 和急性至慢性肝衰竭 (ACLF) 是危及生命的疾病,需要先进的治疗干预措施.
- 外体肝支持系统,包括非生物 (NBAL) 或生物人工肝支持系统 (BAL) 和全器官外体肝 perfusion (W-ECLP),旨在支持肝功能在危急疾病期间.
研究的目的:
- 系统地审查NBAL/BAL和W-ECLP系统在患有ALF和ACLF的成年患者中的安全性和有效性.
- 评估这些系统对生存,不良事件,移植率和肝脏脑病变的影响.
主要方法:
- 对NBAL/BAL系统的随机对照试验 (RCT) (2000-2023) 和W-ECLP (1990-2023) 的观察性研究进行系统审查.
- 数据提取包括研究特征,患者人口统计,干预措施和结果.
- 对NBAL/BAL系统的死亡率和严重不良事件 (SAE) 进行了元分析.
主要成果:
- 与标准医疗治疗相比,NBAL/BAL系统没有显示出与28-30天死亡率 (RR,0.85;p=0.169) 或SAE (RR,1.15;p=0.059) 降低的统计学意义上的关联.
- 亚组分析表明,在ALF患者中,NBAL/BAL对ALF的潜在死亡率有好处 (RR,0.67;p=0.069).
- 在一个小队列 (12名患者) 中,W-ECLP系统成功地将超过一半的重症患者连接到移植,存活并且没有猪逆转录病毒传播.
结论:
- 目前的证据没有证明NBAL/BAL设备对ALF/ACLF患者的死亡率或SAE的综合影响.
- 这些发现凸显了对外体肝支持系统的进一步研究的需要,包括更大的RCT和优化的协议.
- 改善患者选择, perfusion 耐用性和治疗策略对于推进这些技术至关重要.

Acute Respiratory Failure-V
123
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.

Liver Regeneration
3.2K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...
