概括
静脉注射免疫球蛋白 (IVIG) 对患有BK多重瘤病毒 (BKPyV) DNAemia的移植患者是安全的,但其在清除病毒方面的有效性需要进一步调查. 主体免疫反应似乎对病毒控制至关重要.
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
- 病毒学 病毒学
背景情况:
- 乙基多重瘤病毒 (BKPyV) DNAemia 构成移植异构移植失败的重大风险.
- 目前,BKPyV还没有特定的治疗方法,静脉注射免疫球蛋白 (IVIG) 的安全性和免疫效应在受控环境中尚未得到充分证实.
研究的目的:
- 评估IVIG在患有BKPyVDNAemia的移植患者中的安全性和耐受性.
- 研究IVIG对宿主免疫反应的影响,包括中和抗体 (nAb),T细胞和自然杀手细胞 (NKC) 反应.
主要方法:
- 进行了一项多中心,前性,随机,双盲,安慰剂控制的试点研究.
- 患有BKPyVDNAemia的成年移植接受者接受了两次IVIG或安慰剂输液.
- 安全性,耐受性,病毒清除,nAb和细胞免疫反应被监测了一年.
主要成果:
- 用IVIG给药是安全的,耐受性很好,没有报告的不良事件.
- 三个月后病毒清除率在IVIG (40.0%) 和安慰剂 (44.4%) 组之间是相似的.
- 虽然80%的参与者具有基线nAb,但100%在三个月内获得了它们,病毒清除与治疗前更高的BCPyV特异性CD8+T细胞水平相关.
结论:
- 两剂IVIG对于患有BKPyVDNAemia的移植患者是安全的.
- IVIG对病毒清除的直接影响仍然不确定.
- 控制BKPyVDNAemia可能更多地取决于宿主的内在病毒特异性细胞和幽默免疫反应.

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...

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...

01:28Kidney 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...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

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...
