To assess the natural history and outcomes of children with intestinal failure in a large, multicenter, geographically diverse contemporary cohort (2010-2015) from 6 pediatric intestinal failure programs.
Retrospective analysis of a multicenter intestinal failure cohort (n = 443). Competing-risk analysis was used to obtain cumulative incidence rates for the primary outcome (enteral autonomy, transplantation, or death). The χ test and Cox proportional hazard regression were used for bivariate and multivariable analyses.
The study cohort comprised 443 patients (61.2% male). Primary etiologies included short bowel syndrome (SBS), 84.9%; dysmotility disorder, 7.2%; and mucosal enteropathy, 7.9%. Cumulative incidences for enteral autonomy, transplantation, and death at 6 years of follow-up were 53.0%, 16.7%, and 10.5%, respectively. Enteral autonomy was associated with SBS, ≥50% of small bowel length, presence of an ileocecal valve (ICV), absence of portal hypertension, and follow-up in a non-high-volume transplantation center. The composite outcome of transplantation/death was associated with persistent advanced cholestasis and hypoalbuminemia; age <1 year at diagnosis, ICV, and intact colon were protective.
The rates of death and transplantation in children with intestinal failure have decreased; however, the number of children achieving enteral autonomy has not changed significantly, and a larger proportion of patients remain parenteral nutrition dependent. New strategies to achieve enteral autonomy are needed to improve patient outcomes.
评估来自 6 个儿科肠衰竭项目的大型、多中心、地理位置多样化的当代队列(2010-2015 年)中儿童肠衰竭的自然史和结局。
对多中心肠衰竭队列(n=443)进行回顾性分析。采用竞争风险分析获得主要结局(肠内自主、移植或死亡)的累积发生率。χ 检验和 Cox 比例风险回归用于双变量和多变量分析。
研究队列包括 443 名患者(61.2%为男性)。主要病因包括短肠综合征(SBS),占 84.9%;动力障碍性疾病,占 7.2%;黏膜性肠病,占 7.9%。6 年随访时肠内自主、移植和死亡的累积发生率分别为 53.0%、16.7%和 10.5%。肠内自主与 SBS、小肠长度≥50%、存在回盲瓣(ICV)、无门静脉高压和在非高容量移植中心随访有关。移植/死亡的复合结局与持续性进展性胆汁淤积和低白蛋白血症有关;诊断时年龄<1 岁、ICV 和完整结肠是保护性因素。
儿童肠衰竭的死亡率和移植率有所下降;然而,实现肠内自主的儿童数量并未显著增加,更多的患者仍依赖肠外营养。需要新的策略来实现肠内自主,以改善患者的结局。
