RATIONALE Hypermetabolism (HM) in Amyotrophic lateral sclerosis (ALS) is the reflection of a high energy metabolic level, but this alteration seems controversial. The main objective of the study was to confirm the existence of HM during ALS compared to healthy subjects. METHODS A cohort of ALS patients was compared to a control group without metabolic disorder. The assessment included anthropometric criteria measurements, body composition by bioelectric impedance analysis and resting energy expenditure (REE) by indirect calorimetry. HM was defined as a variation > +10% between measured and calculated REE. Statistical analysis used Mann-Withney and Chi2 tests. Multivariate analysis included logistic regression. RESULTS 287 patients and 75 controls were included. The metabolic level was higher in ALS patients (1500 kcal/24 h [1290-1693] vs. 1230 kcal/24 h [1000-1455], p < 0.0001) as well as the REE/fat free mass ratio (33.5 kcal/kg/24 h [30.4-37.8] vs. 28.3 kcal/kg/24 h [26.1-33.6], p < 0.0001). 55.0% of ALS patients had HM vs. 13.3% of controls (p < 0.0001). HM was strongly and positively associated with ALS (OR = 9.50 [4.49-20.10], p < 0.0001). CONCLUSIONS HM in ALS is a reality, which affects more than half of the patients and is associated with ALS. This work confirms a very frequent metabolic deterioration during ALS. The identification of HM can allow a better adaptation of the patients' nutritional intake.

与健康受试者相比,高代谢是肌萎缩侧索硬化症的现实

基本原理 肌萎缩侧索硬化 (ALS) 中的高代谢 (HM) 是高能量代谢水平的反映,但这种改变似乎有争议。该研究的主要目的是确认与健康受试者相比,ALS 期间 HM 的存在。方法将一组 ALS 患者与没有代谢紊乱的对照组进行比较。评估包括人体测量标准测量、生物电阻抗分析的身体成分和间接量热法的静息能量消耗 (REE)。HM 定义为测量的和计算的 REE 之间的变化 > +10%。统计分析使用 Mann-Withney 和 Chi2 检验。多变量分析包括逻辑回归。结果 包括 287 名患者和 75 名对照者。ALS 患者的代谢水平较高(1500 kcal/24 h [1290-1693] vs. 1230 kcal/24 h [1000-1455], p < 0.0001) 以及 REE/无脂肪质量比(33.5 kcal/kg/24 h [30.4-37.8] vs. 28.3 kcal/kg/24 h [26.1- 33.6],p < 0.0001)。55.0% 的 ALS 患者患有 HM,而对照组为 13.3%(p < 0.0001)。HM 与 ALS 呈强正相关(OR = 9.50 [4.49-20.10],p < 0.0001)。结论 ALS 中的 HM 是一个现实,它影响了超过一半的患者并且与 ALS 相关。这项工作证实了 ALS 期间非常频繁的代谢恶化。HM的识别可以更好地适应患者的营养摄入。HM 与 ALS 呈强正相关(OR = 9.50 [4.49-20.10],p < 0.0001)。结论 ALS 中的 HM 是一个现实,它影响了超过一半的患者并且与 ALS 相关。这项工作证实了 ALS 期间非常频繁的代谢恶化。HM的识别可以更好地适应患者的营养摄入。HM 与 ALS 呈强正相关(OR = 9.50 [4.49-20.10],p < 0.0001)。结论 ALS 中的 HM 是一个现实,它影响了超过一半的患者并且与 ALS 相关。这项工作证实了 ALS 期间非常频繁的代谢恶化。HM的识别可以更好地适应患者的营养摄入。
