概括
针对1型原发性高氧化尿 (PH1) 的RNA干扰 (RNAi) 治疗影响移植决策. 可以考虑与RNAi进行隔离性移植 (iKTx),但严重的氧化需要联合肝/移植.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 遗传学 是一个遗传学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 一次性高氧化尿1型 (PH1) 由肝脏氨酸氧化氨基转移酶 (AGT) 缺陷引起,导致过度的氧化酸盐产生.
- 尼多西兰和卢马西兰是RNA干扰 (RNAi) 剂,旨在抑制PH1患者的氧酸盐合成.
- RNAi疗法的出现为PH1患有衰竭的PH1患者进行隔离移植 (iKTx) 开辟了可能性.
研究的目的:
- 评估RNAi疗法 (nedosiran,lumasiran,dRNAi) 对血中氧酸盐水平和在PH1接受血液透析的患者中的系统性氧酸盐分级 (SOG) 的影响.
- 评估PH1患者隔离移植 (iKTx) 的适宜性和结果,这些患者接受了RNAi药物治疗.
- 根据PH1的氧酸盐水平,全身氧化和治疗反应来决定移植.
主要方法:
- 对17名PH1血液透析患者的回顾性分析,这些患者接受了用卢马西兰,内多西兰或双RNAi (dRNAi) 的治疗.
- 在血液透析前 (HD前) 测量血氧沙酸盐 (Pox) 水平.
- 在RNAi治疗前和期间使用骨MRI和斑点心声学评估系统性氧沙酸盐分级 (SOG).
主要成果:
- 四名患者接受了iKTx,其中两人经历了成功,两人复发.
- 用RNAi剂的治疗影响了由于天花的水平,SOG变化和临床恶化而导致移植的决定.
- 移植计划包括5名患者的iKTx和4名患者的肝脏/脏联合移植 (LKTx);三名患者在研究期间死亡.
结论:
- 血氧酸盐不应该是确定移植手术的唯一标准.
- 对于氧沙酸盐沉积量最小,SOG稳定,对维生素B6或有效的RNAi疗法有反应的患者,可以考虑iKTx.
- 严重或恶化的全身氧化症,RNAi治疗期间高水平和最大透析需要重新考虑组合或连续的LKTx而不是iKTx,因为在诊断时严重的疾病会导致高死亡率.

Kidney Transplant II: Surgical Procedure
307
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Kidney Transplant I: Introduction
340
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Bone Marrow Sampling and Transplants
881
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...
