CHEST:循环生物活性肾上腺髓质素(bio-ADM)可以预测脓毒症死亡

2017-04-22 xiangting MedSci原创

在脓毒症中,循环、生物活性形式的肾上腺髓质素的能有助于血流动力学的个体化治疗,同时避免有害影响。其潜在的病理生理作用使得bio-ADM可用于未来的靶向治疗。

肾上腺髓质素(一种参与维持血流动力学稳态的激素)在脓毒症中的生物学作用是存在争议的,因为注射肽或其抗体都可能是有益的。

在多中心白蛋白意大利脓毒症试验(ALBIOS)中将956例脓毒症或脓毒性休克患者随机分配为白蛋白治疗,或使用晶体液进行液体复苏。第1,2和7天评估血浆bio-ADM。测试bio-ADM和其随时间变化与液体疗法、注射血管加压素、器官功能衰竭和死亡率的关系。

第1天血浆bio-ADM(中位数[Q1-Q3],110 [59-198] pg / mL)在脓毒性休克患者中较高,与90天死亡率、多器官功能衰竭、血液动力学支持治疗的平均程度和第一周血浆乳酸盐时间相关。此外,它可以预测入院时无休克患者的突发性心功能障碍(OR [95%CI] 1.9 [1.4-2.5],P<0.0001,bio-ADM浓度增加1个四分位)。在治疗的第一周,Bio-ADM轨迹明确预测90天死亡率,经临床相关协变量调整后(HR [95%CI] 1.3 [1.2-1.4],P<0.0001),第7天降低至110pg / mL以下与90天死亡率明显下降有关。第一周bio-ADM的浓度变化不依赖于白蛋白治疗。

在脓毒症中,循环、生物活性形式的肾上腺髓质素的能有助于血流动力学的个体化治疗,同时避免有害影响。其潜在的病理生理作用使得bio-ADM可用于未来的靶向治疗。
