概括
在接受脏移植的青少年中,贝拉塔cept的排斥率与氨酸抑制剂相似. 然而,在没有排斥的情况下服用贝拉塔塞普的患者经历了功能改善,这表明选择儿科患者的潜在益处.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 免疫学 免疫学 免疫学
- 儿科医学 儿科医学
背景情况:
- 贝拉塔cept (CTLA4-Ig) 在成人移植 (KT) 中显示出有效性,改善存活率和减少捐赠者特异性抗体 (DSA).
- 患有KT的青少年因不坚持而面临更高的移植损失风险,这引起了人们对贝拉塔塞普的长期益处和服用时间表的兴趣.
- 有限的数据存在belatacept在儿科KT接受者的使用.
研究的目的:
- 为了评估从氨尿素抑制剂 (CNIs) 转换为belatacept的青少年的一年结果.
- 为了比较接受贝拉塔塞普的青少年和在CNI上仍然存在的倾向匹配队列之间的结果.
主要方法:
- 一项多中心的回顾性研究,涉及45名青少年,他们在2018年至2021年期间从CNI转换为贝拉塔cept.
- 转换的指示包括CNI毒性,低于最佳的功能或粘附问题.
- 一年结果与CNIs的倾向匹配的队列进行了比较.
主要成果:
- 排斥发生在24%的贝拉塔塞普患者中;比率与CNI组没有显著差异.
- 在没有排斥的情况下服用贝拉塔塞普的患者显示,估计的淋巴细胞过率 (eGFR) 显著增加 (+19%).
- 在使用belatacept时没有观察到增加的感染并发症.
结论:
- 接受贝拉塔塞普的青少年的拒绝率与使用CNI的青少年的拒绝率相当,这突显了这一群体的坚持挑战.
- 贝拉塔塞普特可以为选择的青少年提供好处,特别是那些没有排斥的青少年,表现出改善的功能.
- 需要进一步的研究来确定贝拉塔塞普特在儿科KT中的最佳患者选择标准.

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
64
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...

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Acute Kidney Injury III: Clinical Manifestations
97
Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Tissue Transplantation
524
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.
