概括
已确定的标记物,如年龄,C反应蛋白与白蛋白比率 (CAR),中性粒细胞与淋巴细胞比率 (NLR) 和单细胞与淋巴细胞比率 (MLR) 预测血液透析患者的死亡率. 卡利指数没有显示出预测值,但MLR提供了强大的负预测能力.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 临床生物标志物 临床生物标志物
- 炎症和免疫力 炎症和免疫力
背景情况:
- 慢性病 (CKD) 和末期病 (ESKD) 的血液透析 (HD) 患者因炎症,营养不良和免疫功能障碍而面临高死亡率.
- "C-反应蛋白白蛋白淋巴细胞 (CALLY) 指数是一种新的生物标志物,旨在整合这些病理生理机制.
- 已建立的炎症标志物,如C反应性蛋白与白蛋白比率 (CAR),中性粒细胞与淋巴细胞比率 (NLR) 和单细胞与淋巴细胞比率 (MLR) 也用于评估结果.
研究的目的:
- 评估CALLY指数对血液透析患者全因死亡率的预后值.
- 为了比较CALLY指数的预后表现与既有标志物 (CAR,NLR,MLR) 和患者人口统计数据.
- 确定可靠的生物标志物,以预测血液透析患者中死亡风险.
主要方法:
- 一项回顾性队列研究,涉及106名血液透析患者.
- 在HD发病后三个月收集人口,临床和实验室数据.
- 平均随访时间为24.5个月,以确定所有原因死亡事件.
主要成果:
- 在随访期间,29名患者 (27.3%) 死亡. 不幸存者比较老,冠状动脉疾病较多,透析时间较短.
- 在未幸存者中观察到较低的血红蛋白,肌素和白蛋白水平,以及较高的单细胞对淋巴细胞比率 (MLR).
- 多变量分析确定了年龄,CAR和NLR作为死亡率的独立预测因素. MLR也是一个具有高负预测值的显著预测指标,而CALLY指数则不是.
结论:
- 年龄,CAR,NLR和MLR是血液透析患者死亡率的独立预测因素.
- 在这个群体中,CALLY指数没有显示出独立的预后价值.
- 作为一个潜在的实用生物标志物,MLR出现了具有显著的阴性预测能力的血液透析患者的死亡率,这需要进一步的研究.

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

730
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

01:28Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration
185
Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...
