The aim of this review is to give up-to-date information on intestinal failure-associated liver disease (IFALD) and how its investigation and management has evolved. Despite advances in treatment for patients with intestinal failure, IFALD remains a significant cause of mortality.
Liver biopsy remains as the gold standard for the diagnosis of IFALD, but its invasive nature has prompted assessment of noninvasive techniques. Risk factors for IFALD are both nonnutritional (e.g. sepsis) and nutritional. Strict protocols for the prevention of central venous catheter infections in patients with intestinal failure are well established, as is the optimization of the constituents of parenteral nutrition. Further research comparing the available lipid emulsions has become available. Novel approaches at maximizing intestinal absorption are discussed including glucagon-like peptide-2 analogues, as well as surgical approaches.
Although there are data on the novel investigative and therapeutic strategies for managing IFALD, further study is required to identify a suitable noninvasive technique for earlier diagnosis and then monitoring of IFALD. Further data are also required on the impact of novel therapies aimed at improving absorption and reducing parenteral nutrition load on IFALD occurrence and progression.
本文旨在提供关于肠衰竭相关肝病(IFALD)的最新信息,以及其检查和管理方法的演变。尽管肠衰竭患者的治疗取得了进展,但 IFALD 仍然是导致死亡的重要原因。
肝活检仍然是 IFALD 诊断的金标准,但由于其侵袭性,已经开始评估非侵入性技术。IFALD 的危险因素既有非营养性的(例如败血症),也有营养性的。已经建立了严格的预防肠衰竭患者中心静脉导管感染的方案,并且优化了肠外营养的成分。现在有更多比较现有脂质乳剂的研究。还讨论了最大限度增加肠吸收的新方法,包括胰高血糖素样肽-2 类似物以及手术方法。
虽然有关于 IFALD 管理的新型研究性和治疗性策略的数据,但仍需要进一步研究以确定合适的非侵入性技术,以便更早地诊断 IFALD,并监测其进展。还需要更多关于旨在改善吸收和减少肠外营养负荷的新型疗法对 IFALD 发生和进展的影响的数据。
