BACKGROUND & AIMS: Although home parenteral nutrition (PN) can save the lives of patients with massive bowel loss that results in short-bowel syndrome and intestinal failure, quality of life is impaired by PN and its complications. We examined the 12-month tolerability and efficacy of teduglutide to reduce PN dependency.
Patients who received teduglutide (0.05 or 0.10 mg/kg/d) for 24 weeks in a randomized controlled trial were eligible for a 28-week double-blind extension study; 52 patients were given 52 weeks of the same doses of teduglutide. We investigated the safety, tolerability, and clinical efficacy (defined as a clinically meaningful ≥20% reduction in weekly PN volume from baseline) at week 52.
The most common adverse events reported included headache (35%), nausea (31%), and abdominal pain (25%); 7 patients withdrew because of adverse events (gastrointestinal disorders in 4). Both groups had progressive reduction in PN. At week 52, 68% of the 0.05-mg/kg/d and 52% of the 0.10-mg/kg/d dose group had a ≥20% reduction in PN, with a reduction of 1 or more days of PN dependency in 68% and 37%, respectively. Four patients achieved complete independence from PN.
For patients with short-bowel syndrome intestinal failure, the efficacy of teduglutide was maintained over 52 weeks and the safety profile was sufficient for it to be considered for long-term use. Further studies are needed to determine whether these effects will translate into improved quality of life and reduced PN complications. ClinicalTrials.gov number, NCT00172185.
尽管家庭肠外营养(PN)可以挽救因大量肠损失导致短肠综合征和肠衰竭的患者生命,但 PN 及其并发症会损害生活质量。我们研究了特杜古肽减少 PN 依赖性的 12 个月耐受性和疗效。
在一项随机对照试验中接受特杜古肽(0.05 或 0.10mg/kg/d)治疗 24 周的患者有资格参加 28 周的双盲扩展研究;52 名患者接受了 52 周相同剂量的特杜古肽治疗。我们在第 52 周调查了安全性、耐受性和临床疗效(定义为每周 PN 量从基线减少 ≥20%)。
报告的最常见不良事件包括头痛(35%)、恶心(31%)和腹痛(25%);7 名患者因不良事件(胃肠道疾病 4 例)退出。两组均逐渐减少 PN。第 52 周时,0.05mg/kg/d 组的 68%和 0.10mg/kg/d 组的 52%的 PN 减少量≥20%,分别有 68%和 37%减少了 1 天或更多天的 PN 依赖性。4 名患者完全摆脱了 PN。
对于短肠综合征肠衰竭患者,特杜古肽的疗效在 52 周内保持稳定,安全性足以考虑长期使用。需要进一步研究以确定这些效果是否会转化为改善生活质量和减少 PN 并发症。临床试验注册号,NCT00172185。
