摘要

背景:研究表明,以植物为主的饮食模式对慢性肾脏疾病(CKD)患者有益。目的是研究增加植物性食物摄入的多样性如何影响慢性肾病患者的代谢组学、微生物组学和临床参数。方法:本研究是一项交叉、随机对照试验,涉及25名诊断为3-4期CKD的澳大利亚成年人。参与者被随机分配遵循两种饮食,每种饮食6周,间隔至少4周的洗脱期:高多样性植物性饮食(HDPD,每周≥30种独特的植物性食物)和低多样性植物性饮食(LDPD,每周≤15种独特的植物性食物),以及通常的肾脏饮食处方。在四个时间点(每个干预期的开始和结束)完成数据收集。主要结局包括尿毒症毒素(硫酸吲哚酚和对甲酚硫酸盐)浓度的变化。次要和探索性结局包括饮食质量和营养状况、粪便微生物组组成和多样性、血浆代谢组、症状负担、生活质量评分、血压、生化和人体测量指标。结果:血浆和尿毒血症毒素水平在整个队列中没有持续下降;然而,在HDPD的应答者中观察到显著的减少,特别是那些肾功能较差和基线尿毒症毒素水平较高的患者。两种饮食都不会导致电解质失衡。HDPD显著改善了饮食质量,将潜在的肾酸负荷从基线平均降低了47%,估计边际平均降低了9.96 (95% CI: -16.28至-3.64),与LDPD相比,减少了包括便秘在内的总症状负担(95% CI: -4.11至-0.54和-0.91至-0.22)。它还改变了肠道微生物群,增加了丁酸盐/异丁酸盐等有益代谢物的产生。相反,LDPD降低了微生物多样性,降低了27个物种和33个功能基因的丰度。结论:本研究证明了中度CKD患者每周饮食中加入30种或更多独特植物性食物的安全性和临床相关治疗益处。据观察,患有晚期肾病和尿毒症毒素水平较高的个体可能从采用HDPD中获得最大的益处。试验注册:ACTRN12619000442101。

期刊介绍: The Clinical Journal of the American Society of Nephrology strives to establish itself as the foremost authority in communicating and influencing advances in clinical nephrology by (1) swiftly and effectively disseminating pivotal developments in clinical and translational research in nephrology, encompassing innovations in research methods and care delivery; (2) providing context for these advances in relation to future research directions and patient care; and (3) becoming a key voice on issues with potential implications for the clinical practice of nephrology, particularly within the United States. Original manuscript topics cover a range of areas, including Acid/Base and Electrolyte Disorders, Acute Kidney Injury and ICU Nephrology, Chronic Kidney Disease, Clinical Nephrology, Cystic Kidney Disease, Diabetes and the Kidney, Genetics, Geriatric and Palliative Nephrology, Glomerular and Tubulointerstitial Diseases, Hypertension, Maintenance Dialysis, Mineral Metabolism, Nephrolithiasis, and Transplantation.
