摘要
背景:人们鼓励慢性肾脏病(CKD)患者选择精制谷物而非全谷物,作为控制慢性肾脏病-矿物质和骨骼疾病(CKD-MBD)的低磷饮食的一部分。然而,目前还没有直接证据表明限制全谷物会对慢性肾脏病的治疗结果产生有利影响:本研究通过两种方式分析了慢性肾功能不全队列数据,即横断面 CKD-MBD 生物标志物检查和前瞻性健康结果检查。共纳入了 4067 名(横断面)和 4331 名(前瞻性)参与者。主要暴露指标是报告的全谷物摄入量(以份数/天、份数/1,000 千卡和精制谷物份数/全谷物份数进行分析)。CKD-MBD生物标志物包括血清磷、成纤维细胞生长因子-23、甲状旁腺激素、降钙素三醇和钙。结果包括心血管事件、肾衰竭和全因死亡率:在调整后的模型中,当粗略评估(份/天)时,报告的全谷物摄入量与较高的磷摄入量和血清磷相关,但当分析与能量的关系时,则不相关。与全谷物相比,精制谷物摄入量越高,肾衰竭风险越高(模型 4:1.01,95% CI 1.00 至 1.02;P=0.01),全因死亡率越高(模型 4:1.01,95% CI 1.00 至 1.01;P=0.01),心血管疾病风险越高(完全调整模型除外)。在根据包括肾功能在内的人口统计学和临床因素进行调整的模型中,较高的膳食密度与较低的死亡率相关,但在根据膳食因素进行进一步调整的完全调整模型中,较高的膳食密度与较低的死亡率无关:结论:全谷物摄入量与慢性肾脏病-骨髓增生异常综合征生物标志物无关。与精制谷物相比,全谷物的摄入与较低的心血管疾病、肾衰竭和死亡风险有关。这项研究的结果对长期以来限制慢性肾病患者摄入全谷物的做法提出了质疑。
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.
