Hepatology:门脉性肺动脉高压的肝移植等待患者长期预后

2017-03-20 MedSci MedSci原创

背景:约有2%-6%左右的肝脏移植等待患者被诊断有门脉性肺动脉高压。该研究针对患有门脉性肺动脉高压的肝脏移植等待患者的预后进行了回顾性分析。方法:数据来源于一项前瞻性研究的患者资料。针对门脉性肺动脉高压诊断时、肝脏移植前最近一次评估和肝脏移植后6月内、6月后四个时间点的患者肺血流动力学数据进行收集。结果:49位患者(35位男性,平均年龄48±8岁)纳入研究(MELD评分中位数20分)。基线水平的平

背景:约有2%-6%左右的肝脏移植等待患者被诊断有门脉性肺动脉高压。该研究针对患有门脉性肺动脉高压的肝脏移植等待患者的预后进行了回顾性分析。

方法:数据来源于一项前瞻性研究的患者资料。针对门脉性肺动脉高压诊断时、肝脏移植前最近一次评估和肝脏移植后6月内、6月后四个时间点的患者肺血流动力学数据进行收集。

结果:49位患者(35位男性,平均年龄48±8岁)纳入研究(MELD评分中位数20分)。基线水平的平均肺动脉为44±10mmHg(26-73mmHg),心脏指数为3.5±0.9L/min/m2,肺血管阻力位5.6±2.8Wood单位。35位患者肝脏移植前接受了肺动脉高压靶向治疗,血流动力血再评估显示显着的平均肺动脉高压(36±7mmHg VS 47±10mmHg)和肺血管阻力(3.0±1.4 VS 6.1±3.1mmHg)下降。14位患者在肝脏移植前死亡。35位患者接受肝脏移植,术后中位随访时间为38个月。8位患者肝脏移植后死亡,其中5位死于门脉性肺动脉高压(术后1天至术后6月)。在27位存活者中,所有接受静脉依前列醇治疗的患者肝移植术后停用该药,内皮素受体拮抗剂或磷酸二酯酶5抑制剂在15/27名患者中继续使用。最近一次评估,27名患者中有20人平均肺动脉压小于35mmHg,8人小于25mmHg。预期肝脏移植术后6月、1年和3年的总体生存率分别为80%、77%和77%。

结论:通过联合肺动脉高压靶向药物和肝脏移植,在等待肝脏移植的患者中,稳定或逆转门脉性肺动脉高压似乎是一个可达到的目标。

hepatology:等待肝脏移植患者治疗HCV的更佳时机

口服直接抗病毒药物的出现业已改变了肝脏移植前或肝脏移植后的丙型肝炎病毒治疗模式。移植前或移植后抗丙型肝炎病毒治疗需要进行权衡,因为抗丙肝病毒治疗可改善肝脏功能,继而降低了肝脏移植的必要性。我们研究旨在识别基于MELD评分适合肝脏移植的肝硬化失代偿患者移植前治疗将会从中获益(或不获益)。我们模拟了一个虚拟的试验,对比MELD评分在10-40之间的患者肝脏移植前或肝脏移植后使用口服直接抗病毒药物治疗丙

Scientifc reports:移植肝脏体外保存新策略

近日,日本科学家在国际学术期刊scientific reports在线发表了一项最新研究进展,他们开发出一种新的肝脏灌注培养系统,利用这套系统能够维持肝脏在体外状态下的基本生物学过程和基本生理功能,对于肝脏移植过程中供体肝脏的保存以及严重缺血肝脏的复苏都具有重要作用。   三维多细胞生物由执行不同功能的细胞构成不同器官和组织,再有序形成不同系统,最终构成一个完整个体。但要维持生命

STM:病毒感染有利于器官移植?

慢性丙肝病毒(HCV)感染,是肝脏移植的最常见原因。移植之后,机体内的丙肝病毒仍会感染新肝脏,免疫系统在那里高度活跃。 德国Helmholtz 中心和慕尼黑工业大学TUM的科学家们发现,尽管免疫非常活跃,但新移植的肝脏并不会因此而受到排斥。病毒对先天免疫系统的长期刺激,实际上提高了机体的耐受几率。这项研究发表在六月二十五日的Science Translational
