Current medical management of short bowel syndrome (SBS) involves the use of lifelong parenteral nutrition (PN). Glucagon-like peptide-2 (GLP-2), an important intestinotrophic growth factor has been shown to increase intestinal absorption in SBS through augmentation of post-resection intestinal adaptation. This may lead to the reduction of PN dependence in patients with SBS.
Advancing research of GLP-2 physiology has spurred the growing understanding of the diverse effects of GLP-2. The development of the degradation resistant GLP-2 analog, teduglutide (Gattex(TM), NPS Pharmaceuticals, Bedminster, NJ), has allowed its exploration as a therapeutic agent in a variety of clinical settings. Recent multicenter, placebo-controlled studies of GLP-2 in SBS patients demonstrate meaningful reductions in PN requirements with good safety profiles. The reparative and immunomodulatory effects of teduglutide may also be beneficial in patients with inflammatory bowel disease (IBD). Safety concerns about possible carcinogenic properties during long-term use require ongoing evaluation.
GLP-2 appears to offer a novel adjuvant treatment modality for SBS. Promise for its use in other clinical settings like IBD has been shown in small pilot studies.
短肠综合征(SBS)目前的医学管理涉及终身肠外营养(PN)。胰高血糖素样肽-2(GLP-2)是一种重要的肠营养生长因子,已被证明可通过增强切除术后肠道适应性来增加SBS患者的肠道吸收。这可能会减少SBS患者对PN的依赖。
GLP-2生理学的不断发展推动了对GLP-2多种作用的深入理解。抗降解GLP-2类似物替度鲁肽(Gattex™,NPS制药公司,新泽西州贝德明斯特)的开发,使其能够在各种临床环境中作为治疗药物进行探索。最近在SBS患者中进行的多中心、安慰剂对照研究表明,PN需求有显著降低,且安全性良好。替度鲁肽的修复和免疫调节作用对炎症性肠病(IBD)患者可能也有益处。长期使用可能存在致癌特性的安全问题需要持续评估。
GLP-2似乎为SBS提供了一种新的辅助治疗方式。在小型试点研究中已显示出其在IBD等其他临床环境中使用的前景。
