概括
在移植 (KTX) 后长期使用尿路支架 (UrSt) 与增加BK多瘤病毒 (BKPyV) DNAemia风险有关. 将UrSt停留时间限制在8周以下可能会减轻KTX接受者的BKPyV并发症.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 病毒学 病毒学
- 移植手术 移植手术
背景情况:
- 乙基多瘤病毒 (BKPyV) 对移植 (KTX) 接受者构成重大威胁,可能导致乙基多瘤病毒相关的病.
- 预防性尿路支架 (UrSt) 放置是KTX后的标准护理,但其对BKPyV-DNAemia的影响正在调查中.
研究的目的:
- 研究KTX接受者的UrSt安置,内置时间和BKPyV-DNAemia风险之间的关系.
- 为了确定是否存在持续的UrSt和BKPyV-DNAemia发病率之间的剂量依赖关系.
主要方法:
- 一项追溯的病例对照研究,涉及KTX接受者可检测到BKPyV-DNAemia和匹配的对照没有DNAemia.
- 在维也纳医学大学从2010年到2021年收集的数据.
- 分析重点是UrSt安置及其持续时间作为BKPyV-DNAemia的潜在风险因素.
主要成果:
- UrSt安置本身与BKPyV-DNAemia风险没有显著的关联 (OR 1.20).
- 然而,超过8周的住院时间是BKPyV-DNAemia (OR 1.79,p=0.02) 的显著预测因素,在多变量分析中独立证实 (aOR 1.74,p=0.03).
- 局限性包括回顾性,单中心设计.
结论:
- 预防性UrSt安置不会增加KTX后的BKPyV-DNAemia风险.
- 建议将UrSt停留时间限制在8周以下,以减少BKPyV-DNAemia的风险.
- 在临床上可行的情况下,应尽早进行UrSt去除,理想情况下在8周内,以减轻BKPyV风险.

Kidney Transplant I: Introduction
312
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 Pyelonephritis II: Diagnostic Studies and Management
291
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Acute Pyelonephritis I: Introduction
447
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...
