在非活性炎症性肠病 (IBD) 中,准确的休息代谢率 (RMR) 估计至关重要. 只有安乔斯等人. 该方程可靠地估计了IBD患者的RMR,尽管由于广泛的协议限制,个人应用需要谨慎.
科学领域:
- 代谢医学是一种代谢医学.
- 胃肠病学 胃肠病学
- 临床营养学 临床营养学
背景情况:
- 休息代谢率 (RMR) 是能源消耗的一个关键指标.
- 准确的RMR估计对于慢性疾病如炎症性肠病 (IBD) 的营养管理至关重要.
- 以前的研究表明,在不同患者群体的RMR预测方程中存在变化.
研究的目的:
- 为了比较测量的RMR (mRMR) 与通过各种预测方程估计的RMR,在非活跃的IBD门诊患者中.
- 评估选定的RMR方程的准确性和一致性 (Cunningham,Henry,Anjos等,Marra等). 在这个特定的患者群体中.
主要方法:
- 72名成年IBD患者 (45名克罗恩病患者) 接受间接热量测量以测量mRMR.
- 用四个预测方程来估计RMR:坎宁汉,亨利,安乔斯等人,马拉等人.
- 用DXA评估身体组成;使用Bland&Altman分析计算偏差和一致极限 (LoA).
主要成果:
- 在克罗恩病和性结肠炎患者之间,没有发现年龄,身体组成或mRMR的显著差异.
- 只有安乔斯等人. 方程式显示了准确的RMR估计 (偏差:-52.1 kJ/day,LoA:-1311到1206 kJ/d).
- 马拉和其他人. 方程式的偏差率最高 (24.1 ± 14.8%);所有方程式的LoA范围都相似. 与身体质量 (BM) 相比,无脂肪质量 (FFM) 提高了预测准确度.
结论:
- 安乔斯和其他人. 该方程是测试患者中非活跃IBD门诊患者估计RMR的唯一经过验证的方法.
- 尽管它是准确的,但广泛的LoA在应用这个方程对个体患者的评估时需要谨慎.
- 可能需要进一步的研究来完善IBD患者的RMR预测模型.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
