预后营养指数 (PNI) 是预测血液透析患者生存的可靠指标. 较高的PNI值与死亡风险降低有关,使其成为一种有价值的预后工具.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 临床医学 临床医学
- 生物统计学 生物统计学
背景情况:
- 炎症和营养状况显著影响血液透析患者的治疗结果.
- 预后营养指数越来越多地用于评估患者的风险.
- 在大型队列中重新评估这些指数对于临床实践至关重要.
研究的目的:
- 重新评估炎症和营养相关指数的预后价值.
- 为了比较大型血液透析队列中各种指标的预测能力.
- 确定血液透析患者整体存活 (OS) 的最可靠指标.
主要方法:
- 对6679名血液透析患者进行了回顾性队列研究.
- 从常规实验室参数计算指数.
- 使用卡普兰-梅尔曲线和多变量考克斯模型的生存分析;用于预测能力评估的C指数,ROC和决策曲线分析.
主要成果:
- 预后营养指数 (PNI),淋巴细胞与CRP比率 (LCR),CRP与白蛋白比率 (CAR),全身免疫炎症指数 (SII) 和中性细胞与淋巴细胞比率 (NLR) 是OS的独立预测指标.
- 血小板与淋巴细胞比率 (PLR) 并不是一个独立的预测因素.
- PNI表现出优异的区分能力,与增加的PNI相关的死亡风险降低 (调整后HR为0.78). 最佳的PNI截止点是42.3.3.
结论:
- 对于血液透析患者来说,PNI是一个比LCR,CAR,SII,PLR和NLR更可靠的预后指标.
- 有效评估PNI可以识别高风险个体.
- 在临床环境中,PNI是血液透析患者的重要预后工具.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
