Amyloidosis is a heterogeneous disease characterized by tissue deposition of abnormally folded fibrillary proteins that can manifest itself by a wide variety of symptoms depending on the affected organs. GI involvement among amyloidosis patients is common. Its clinical manifestation often presents with nonspecific symptoms such as weight loss, diarrhea, and malabsorption. With no specific treatment existing for GI amyloidosis, therapy focuses on impeding amyloid deposition and managing the patients' symptoms with supportive measures. Here, we present an AL-amyloidosis patient with GI involvement and intestinal failure (IF) who was successfully treated with the glucagon-like peptide-2 (GLP-2) analogue teduglutide. Over the course of treatment with teduglutide, the patient was able to achieve independence from parenteral nutrition and experienced a significant improvement in quality of life (QoL) as stool frequency and consistency improved, urinary output was stabilized and body weight as well as body composition improved over the course of teduglutide therapy. With no longer being exposed to the burden and associated risks of parenteral nutrition, we were able to reduce the potential morbidity and mortality rate as well as to improve the patient's overall QoL. Intestinal tissue biopsy workup revealed a histopathological correlate for the clinical response; Congo-Red-positive intestinal depositions almost completely disappeared within 6 months of teduglutide therapy. Implementing intestinotrophic GLP-2 analogue teduglutide may enrich the spectrum of treatment options for amyloidosis patients with IF who are dependent on parenteral support.
淀粉样变性是一种异质性疾病,其特征是异常折叠的纤维状蛋白在组织中沉积,根据受影响的器官不同,可表现出各种各样的症状。淀粉样变性患者的胃肠道受累很常见。其临床表现常为体重减轻、腹泻和吸收不良等非特异性症状。由于目前尚无针对胃肠道淀粉样变性的特异性治疗方法,治疗主要集中在阻止淀粉样蛋白沉积,并通过支持性措施来控制患者的症状。在此,我们报告一例伴有胃肠道受累和肠衰竭(IF)的AL淀粉样变性患者,该患者接受胰高血糖素样肽-2(GLP-2)类似物替度鲁肽治疗后获得成功。在接受替度鲁肽治疗的过程中,患者能够摆脱肠外营养,随着大便频率和稠度改善、尿量稳定,以及在替度鲁肽治疗过程中体重和身体组成得到改善,患者的生活质量(QoL)有了显著提高。由于不再承受肠外营养的负担和相关风险,我们能够降低潜在的发病率和死亡率,并改善患者的总体生活质量。肠道组织活检检查揭示了临床反应的组织病理学相关性;在替度鲁肽治疗6个月内,刚果红阳性的肠道沉积物几乎完全消失。应用肠营养性GLP-2类似物替度鲁肽可能会丰富对依赖肠外支持的IF淀粉样变性患者的治疗选择范围。
