概括
肝移植接受者需要替代疗法面临更高的急性排斥率和更低的存活率. 谨慎的免疫抑制管理至关重要,以平衡感染和排斥风险在这个脆弱的群体.
科学领域:
- 肝病学和移植外科手术
- 病学和脏替代疗法治疗
- 免疫抑制和移植后的并发症
背景情况:
- 肝移植后的功能障碍会增加发病率和死亡率.
- 肝移植后需要替代疗法 (RRT) 的患者具有特别高的风险.
- 有限的数据存在于肝移植接受者需要RRT的排斥结果.
研究的目的:
- 为了评估活检证明的急性排斥在需要RRT的肝移植接受者的发病率.
- 在这个队列中评估接受者和移植者的存活率,感染率和免疫抑制策略.
- 为了比较肝移植接受者与没有RRT之间的结果.
主要方法:
- 单中心,回顾性队列研究.
- 包括已故的捐赠人肝移植接受者 (≥18岁) 在2017年1月至2019年8月期间移植.
- 患者接受了仅类固醇诱导和塔克罗利斯;比较那些需要RRT (N=86) 和没有RRT (N=158) 的患者.
主要成果:
- 在RRT组中,在1年内经过活检证明的急性排斥显著更高 (36%对13%,P<.001).
- 需要RRT的患者,12个月的患者存活率较低 (77%vs94%,P<.001).
- 感染,而不是排斥,是死亡率的独立预测因素 (HR 3.8,P<.001).
结论:
- 需要RRT的肝移植接受者经历了明显更高的急性排斥率和更低的患者存活率.
- 在这个人群中,感染带来了比拒绝更大的独立死亡风险.
- 仔细的免疫抑制定位对于减轻肝移植接受者需要RRT的感染和排斥风险至关重要.

Tissue Transplantation
375
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Renal Failure: Dose Adjustments
95
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.
