Elevated international normalized ratio of prothrombin time (PT-INR) is one of the key characteristics of acute-on-chronic liver failure (ACLF). Whether the staging of PT-INR has the ability to screen out subgroups of ACLF patients who would be more eligible for artificial liver support system (ALSS) treatment has not been studied in detail.
A previous study enrolled patients receiving ALSS treatment with regional citrate anticoagulation from January 2018 to December 2019. Patients with different PT-INR intervals were retrospectively enrolled: 1.3 ≤ PT-INR < 1.5 (Pre-stage), 1.5 ≤ PT-INR < 2.0 (Early-stage), 2.0 ≤ PT-INR < 2.5 (Mid-stage), and PT-INR ≥ 2.5 (End-stage). The Cox proportional hazards models were used to estimate the association between stages of ACLF or sessions of ALSS treatment and 90 day mortality.
A total of 301 ACLF patients were enrolled. The 90 day mortality risk of Early-stage ACLF patients (adjusted hazard ratio (aHR) (95% confidence interval (CI)), 3.20 (1.15-8.89), = 0.026), Mid-stage ACLF patients (3.68 (1.34-10.12), = 0.011), and End-stage ACLF patients (12.74 (4.52-35.91), < 0.001) were higher than that of Pre-stage ACLF patients, respectively. The 90 day mortality risk of Mid-stage ACLF patients was similar to that of Early-stage ACLF patients (1.15 (0.69-1.94), = 0.591). The sessions of ALSS treatment was an independent protective factor (aHR (95% CI), 0.81 (0.73-0.90), < 0.001). The 90 day mortality risk in ACLF patients received 3-5 sessions of ALSS treatment was lower than that of patients received 1-2 sessions (aHR (95% CI), 0.34 (0.20-0.60), < 0.001), whereas the risk in patients received ≥6 sessions of ALSS treatment was similar to that of patients received 3-5 sessions (0.69 (0.43-1.11), = 0.128).
ACLF patients in Pre-, Early-, and Mid-stages might be more eligible for ALSS treatment. Application of 3-5 sessions of ALSS treatment might be reasonable.
凝血酶原时间国际标准化比值(PT-INR)升高是慢加急性肝衰竭(ACLF)的关键特征之一。PT-INR分期是否有能力筛选出更适合人工肝支持系统(ALSS)治疗的ACLF患者亚组,尚未进行详细研究。
一项既往研究纳入了2018年1月至2019年12月接受局部枸橼酸抗凝ALSS治疗的患者。回顾性纳入不同PT-INR区间的患者:1.3≤PT-INR<1.5(前期)、1.5≤PT-INR<2.0(早期)、2.0≤PT-INR<2.5(中期)和PT-INR≥2.5(末期)。采用Cox比例风险模型评估ACLF分期或ALSS治疗疗程与90天死亡率之间的关联。
共纳入301例ACLF患者。早期ACLF患者(校正风险比(aHR)(95%置信区间(CI)),3.20(1.15 - 8.89),P = 0.026)、中期ACLF患者(3.68(1.34 - 10.12),P = 0.011)和末期ACLF患者(12.74(4.52 - 35.91),P<0.001)的90天死亡风险分别高于前期ACLF患者。中期ACLF患者的90天死亡风险与早期ACLF患者相似(1.15(0.69 - 1.94),P = 0.591)。ALSS治疗疗程是一个独立的保护因素(aHR(95%CI),0.81(0.73 - 0.90),P<0.001)。接受3 - 5次ALSS治疗的ACLF患者90天死亡风险低于接受1 - 2次治疗的患者(aHR(95%CI),0.34(0.20 - 0.60),P<0.001),而接受≥6次ALSS治疗的患者风险与接受3 - 5次治疗的患者相似(0.69(0.43 - 1.11),P = 0.128)。
前期、早期和中期ACLF患者可能更适合ALSS治疗。应用3 - 5次ALSS治疗可能是合理的。
