概括
在心脏移植 (HTX) 之前,C-反应蛋白 (CRP) 的升高表明死亡风险更高,特别是因感染. 监测移植前的CRP水平可以帮助确定需要更密切的随访的患者,以获得更好的移植后结果.
科学领域:
- 心脏病学 心脏病学
- 移植免疫学 移植免疫学
- 生物化学 生物化学
背景情况:
- 心脏移植接受者需要终身免疫抑制,增加感染风险.
- C-反应蛋白 (CRP) 是炎症和感染严重程度的标志物.
- 心脏移植前CRP升高 (≥20毫克/升) 对心脏移植结果的预后值以前尚不清楚.
研究的目的:
- 研究移植前C反应蛋白 (CRP) 水平升高对心脏移植 (HTX) 后结果的影响.
- 确定移植前CRP≥20 mg/L是否是HTX后死亡的独立预测因子.
主要方法:
- 对418名心脏移植接受者的回顾性,观察性,单中心研究 (2000-2019).
- 患者根据移植前的CRP水平 (<20 mg/L与≥20 mg/L) 进行分组.
- 分析包括捐赠者/接受者特征,药物治疗和移植后死亡率,包括死亡原因.
主要成果:
- 24.4%的患者在移植前有CRP≥20 mg/L.
- 移植前CRP升高与30天,1年,2年和5年死亡率显著增加有关.
- 感染/败血症,特别是肺部感染,是患有较高CRP水平的患者在五年内死亡的更常见原因.
- 移植前CRP≥20 mg/L是5年移植后死亡率的独立预测因子 (HR: 1.630).
结论:
- 移植前CRP≥20 mg/L可以识别患有感染相关死亡风险增加的心脏移植候选人.
- 肺部感染是这些高风险患者的一个重大问题.
- 强化移植前的感染查和移植后的密切的感染监测建议在CRP升高的患者.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
651
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Kidney Transplant II: Surgical Procedure
559
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
586
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...

Kidney Transplant III: Nursing Management
454
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...
