The current international guideline recommended 200 mg/day of hydrocortisone intravenously to treat septic shock. However, a subsequent study on cortisol metabolism actually showed an increase in cortisol level during sepsis. Hence, the smaller hydrocortisone dose of 100 mg/day might be sufficient and reduce steroid-associated complications. We aimed to compare the clinical outcomes of minimized hydrocortisone dose of 100 mg to the currently recommended dose in the treatment of septic shock patients.
A double-blinded randomized controlled trial included 80 septic shock patients with hemodynamic instability despite fluid and vasopressive therapy. Participants were divided equally into two groups to treat with 100 mg/day or 200 mg/day of hydrocortisone, then stepwise down titrated and discontinued on day 8. The outcome of interest was the hyperglycemic rate. Vital status, time to shock reversal, superinfection and gastrointestinal bleeding rates were also compared.
Patients with 100 mg hydrocortisone had significantly lower hyperglycemic rate compared with 200 mg, 63.9% versus 86.5% (the adjusted hazard ratio [HR], 0.08; 95% confidence interval [CI], 0.02-0.41, P = 0.002). Time to shock reversal was shorter in patients with 100 mg hydrocortisone, 2 days vs. 4 days, P = 0.031. The 28-day mortality rate when adjusted for Simplified Acute Physiology Score II showed no significant difference (HR, 0.68; 95% CI, 0.37-1.24, P = 0.209). The reinfection and gastrointestinal bleeding rates were comparable between groups.
Minimized daily hydrocortisone dosage of 100 mg could lower the occurrence of hyperglycemia without increasing mortality in septic shock, compared with the currently recommended dosage of 200 mg/day.
目前的国际指南建议静脉给予 200mg/天的氢化可的松治疗感染性休克。然而,随后关于皮质醇代谢的研究实际上表明,在脓毒症期间皮质醇水平增加。因此,较小剂量的 100mg/天的氢化可的松可能就足够了,并减少类固醇相关并发症。我们旨在比较小剂量 100mg 氢化可的松与目前推荐剂量在治疗感染性休克患者中的临床结局。
一项双盲随机对照试验纳入了 80 例血流动力学不稳定的感染性休克患者,尽管进行了液体和血管加压治疗。参与者等分为两组,分别接受 100mg/天或 200mg/天的氢化可的松治疗,然后逐步滴定并在第 8 天停药。主要结局为高血糖发生率。还比较了两组患者的存活状态、休克逆转时间、继发感染和胃肠道出血发生率。
接受 100mg 氢化可的松治疗的患者高血糖发生率明显低于接受 200mg 氢化可的松治疗的患者,分别为 63.9%和 86.5%(调整后的危险比 [HR],0.08;95%置信区间 [CI],0.02-0.41,P=0.002)。接受 100mg 氢化可的松治疗的患者休克逆转时间更短,为 2 天,而接受 200mg 氢化可的松治疗的患者为 4 天,P=0.031。调整简化急性生理学评分 II 后,28 天死亡率无显著差异(HR,0.68;95%CI,0.37-1.24,P=0.209)。两组继发感染和胃肠道出血发生率相当。
与目前推荐的 200mg/天剂量相比,小剂量 100mg/天的氢化可的松可以降低感染性休克患者高血糖的发生率,而不增加死亡率。
