BACKGROUND & AIMS: Large-volume paracentesis (LVP) is the treatment of choice for patients with cirrhosis and refractory ascites. However, LVP can lead to postparacentesis circulatory dysfunction (PCD), which is associated with faster ascites recurrence and renal failure. PCD results from vasodilatation, which reduces effective blood volume, and is prevented by intravenous administration of albumin. Vasoconstrictors could be used instead of albumin and, with longer use, prevent PCD and delay ascites recurrence.
We performed a multicenter, randomized, double-blind, placebo-controlled trial to compare albumin with the vasoconstrictor combination of octreotide and midodrine in patients with refractory ascites who underwent LVP. Patients in the albumin group received a single intravenous dose of albumin at the time of LVP plus placebos for midodrine and octreotide (n = 13). Patients in the vasoconstrictor group received saline solution (as a placebo for albumin), 10 mg of oral midodrine (3 times/day), and a monthly 20-mg intramuscular injection of long-acting octreotide (n = 12). Patients were followed up until recurrence of ascites.
The median times to recurrence of ascites were 10 days in the albumin group and 8 days in the vasoconstrictor group (P = .318). There were no significant differences in PCD between the albumin group (18%) and the vasoconstrictor group (25%, P = .574). When ascites recurred, serum levels of creatinine were higher in the vasoconstrictor group (1.2 vs 0.9 mg/dL in the albumin group; P = .051).
The combination of midodrine and octreotide after LVP is not superior to albumin in delaying recurrence of ascites or preventing PCD in patients with cirrhosis. Outcomes appear to be worse in patients given octreotide and midodrine. ClinicalTrials.gov number, NCT00108355.
大量腹腔穿刺术(LVP)是治疗肝硬化和难治性腹水的首选方法。然而,LVP 可导致穿刺后循环功能障碍(PCD),这与更快的腹水复发和肾衰竭有关。PCD 是由于血管扩张导致有效血容量减少引起的,通过静脉输注白蛋白可以预防。血管收缩剂可以替代白蛋白,并且长期使用可以预防 PCD 并延迟腹水复发。
我们进行了一项多中心、随机、双盲、安慰剂对照试验,比较了白蛋白与奥曲肽和米多君联合的血管收缩剂在接受 LVP 的难治性腹水患者中的疗效。白蛋白组患者在 LVP 时接受单次静脉注射白蛋白,并接受米多君和奥曲肽安慰剂(n = 13)。血管收缩剂组患者接受生理盐水(作为白蛋白的安慰剂)、10 mg 米多君(每天 3 次)和每月 20 mg 长效奥曲肽肌内注射(n = 12)。患者随访至腹水复发。
白蛋白组和血管收缩剂组腹水复发的中位时间分别为 10 天和 8 天(P =.318)。白蛋白组(18%)和血管收缩剂组(25%,P =.574)之间 PCD 无显著差异。当腹水复发时,血管收缩剂组的血清肌酐水平较高(1.2 与白蛋白组的 0.9 mg/dL;P =.051)。
在肝硬化患者中,LVP 后给予米多君和奥曲肽联合治疗在延迟腹水复发或预防 PCD 方面并不优于白蛋白。给予奥曲肽和米多君的患者结局似乎更差。ClinicalTrials.gov 注册号,NCT00108355。
