Recent studies have reported a high prevalence of relative adrenal insufficiency in patients with liver cirrhosis. However, the effect of corticosteroid replacement on mortality in this high-risk group remains unclear. We examined the effect of low-dose hydrocortisone in patients with cirrhosis who presented with septic shock.
We enrolled patients with cirrhosis and septic shock aged 18 years or older in a randomized double-blind placebo-controlled trial. Relative adrenal insufficiency was defined as a serum cortisol increase of less than 250 nmol/L or 9 μg/dL from baseline after stimulation with 250 μg of intravenous corticotropin. Patients were assigned to receive 50 mg of intravenous hydrocortisone or placebo every six hours until hemodynamic stability was achieved, followed by steroid tapering over eight days. The primary outcome was 28-day all-cause mortality.
The trial was stopped for futility at interim analysis after 75 patients were enrolled. Relative adrenal insufficiency was diagnosed in 76% of patients. Compared with the placebo group (n = 36), patients in the hydrocortisone group (n = 39) had a significant reduction in vasopressor doses and higher rates of shock reversal (relative risk [RR] 1.58, 95% confidence interval [CI] 0.98-2.55, p = 0.05). Hydrocortisone use was not associated with a reduction in 28-day mortality (RR 1.17, 95% CI 0.92-1.49, p = 0.19) but was associated with an increase in shock relapse (RR 2.58, 95% CI 1.04-6.45, p = 0.03) and gastrointestinal bleeding (RR 3.00, 95% CI 1.08-8.36, p = 0.02).
Relative adrenal insufficiency was very common in patients with cirrhosis presenting with septic shock. Despite initial favourable effects on hemodynamic parameters, hydrocortisone therapy did not reduce mortality and was associated with an increase in adverse effects.

最近的研究报告称,肝硬化患者中相对肾上腺功能不全的患病率很高。然而,皮质类固醇替代治疗在这一高危人群中的死亡率影响仍不清楚。我们研究了小剂量氢化可的松治疗伴有败血症性休克的肝硬化患者的效果。
我们进行了一项随机、双盲、安慰剂对照试验,纳入了年龄在 18 岁及以上的肝硬化合并败血症性休克患者。相对肾上腺功能不全的定义为静脉给予 250μg 促皮质素后,血清皮质醇水平较基线增加<250nmol/L 或<9μg/dL。患者被随机分为每 6 小时接受 50mg 静脉氢化可的松或安慰剂治疗,直至达到血流动力学稳定,然后在 8 天内逐渐减少类固醇剂量。主要结局为 28 天全因死亡率。
在纳入 75 例患者后,中期分析显示试验因无效而停止。76%的患者诊断为相对肾上腺功能不全。与安慰剂组(n=36)相比,氢化可的松组(n=39)的血管加压剂剂量显著减少,休克逆转率更高(相对风险 [RR] 1.58,95%置信区间 [CI] 0.98-2.55,p=0.05)。氢化可的松的使用与 28 天死亡率的降低无关(RR 1.17,95%CI 0.92-1.49,p=0.19),但与休克复发(RR 2.58,95%CI 1.04-6.45,p=0.03)和胃肠道出血(RR 3.00,95%CI 1.08-8.36,p=0.02)的增加有关。
肝硬化伴败血症性休克患者中相对肾上腺功能不全非常常见。尽管最初对血流动力学参数有有利影响,但皮质醇治疗并不能降低死亡率,反而会增加不良反应。(当前对照试验登记号:ISRCTN99675218。)
