简要总结
Assessment of the Safety and efficacy of an amino acid blend on muscle and gut functionality in Intensive Care Unit (ICU) patients.
Since this was a proof of concept, exploratory trial, we assessed different primary outcomes without hierarchy.
详细描述
This monocentric trial was a parallel, randomized, double-blind, controlled study. Patients hospitalized in the ICU for sepsis or ARDS were enrolled.
The treatment group (n=15) was administered the study product (amino acid blend) and the negative control group (=15) was administrated maltodextrin only. The mode of administration was nasogastric probe.
The treatment period was 21 days. Subject were followed during stay in High care and intermediate care units up to 2 months or after hospital discharge with a follow up until 12 months.
Recruitment stopped when 30 patients (15 in each group) reached V4.

结局指标
主要结局
Efficacy: gut barrier structure and functionality improvement
时间窗: 12 months from the beginning of the intervention (timepoints: D1, D7, D14, D21, D60, D180, D365)
i. Enterocytes damage by measurement of I-FABP (intestinal fatty acid-binding protein) in plasma and urine. ii. Functional enterocyte mass by citrulline plasma concentration. iii. Gut barrier function by the translocation of bacteria based on plasma D-Lactate concentration
Efficacy: general recovery improvement
时间窗: 12 months from the beginning of the intervention (timepoints: D1, D7, D14, D21, D60, D180, D365)
i. Length of stay (LOS) in High care and intermediate care units. ii. Time (days) free of ventilation until discharge high care. iii. Time (days) to recover on walking with or without aid
Safety: Renal function change
时间窗: 60 days from the beginning of the intervention
Renal function will be daily assessed from urine output, serum creatinin and glomerular filtration rate
Efficacy: inflammatory status change
时间窗: 12 months from the beginning of the intervention (timepoints: D1, D7, D14, D21, D60, D180, D365)
i. Calprotectin in feces, which is secreted by the neutrophils of the gut mucosae and is released in the gut when the mucosa is inflamed. ii. Acute phase protein concentration in plasma (CRP, fibrinogen, ferritin, prealbumin)
Nutrient profiling
时间窗: Over 60 days from the beginning of intervention (timepoints: D1, D7, D14, D21, D60)
Nutrient profiling will be assessed from blood metabolomics analyses
Efficacy: muscle functionality change
时间窗: 12 months from the beginning of the intervention (timepoints: D1, D7, D14, D21, D60, D180, D365)
i. Muscle (quadriceps) extension isometric strength in response to magnetic stimulation; diaphragm muscle strength in response to magnetic stimulation. Forced vital capacity and maximal inspiratory and expiratory pressures will systematically be recorded. ii. Loss in quadriceps muscle mass and metabolism will be measured by Magnetic resonance imaging. Muscle protein catabolism will be evaluated from measures of 3-methyl histidine in the 24-h urine (reported to urine creatinine).
