Am J Med:CA125指导下的利尿策略能显著改善急性心衰和肾功能障碍患者短期的肾功能

2021-03-01 MedSci原创 MedSci原创

急性心力衰竭和肾功能障碍患者的最佳利尿治疗策略仍不明确。血浆碳水化合物抗原125(CA125)是液体超负荷的代用指标,也是指导利尿治疗的潜在有价值的工具。

急性心力衰竭和肾功能障碍患者的最佳利尿治疗策略仍不明确。血浆碳水化合物抗原125(CA125)是液体超负荷的代用指标,也是指导利尿治疗的潜在有价值的工具。

近日,一项多中心、开放标签研究探究了急性心力衰竭和肾功能障碍患者中CA125指导下的利尿策略治疗对患者短期肾功能的影响,发现CA125指导下的利尿策略能显著改善这类患者72小时的eGFR和其他肾功能参数,研究结果发表于Am J Med。

研究纳入160名急性心力衰竭和肾功能障碍的患者,随机分为2组(1:1):CA125指导治疗组(n = 79)和常规护理组(n = 81)。主要终点是72小时和24小时时估计肾小球滤过率(eGFR)的变化。

 

患者的平均年龄为78±8岁,氨基末端促脑钠肽中位数为7765pg/mL,平均eGFR为33.7±11.3mL/min/1.73m2。在72小时内,与常规护理相比,CA125组接受了更高剂量的呋塞米(P = 0.011),导致尿量也更高(P = 0.042)。此外,CA125>35 U/mL组患者接受的呋塞米剂量最高(P <0.001),利尿效果最佳(P = 0.013)。72小时时,CA125组的eGFR(mL/min/1.73m2)显著改善(37.5 vs 34.8,P = 0.036),24小时时无明显变化(35.8 vs 39.5,P = 0.391)。

综上所述,该研究结果表明,CA125指导下的利尿策略能显著改善急性心力衰竭和肾功能障碍患者72小时的eGFR和其他肾功能参数。
