Abstract

Background: There is a scarcity of large randomized clinical trials on the efficacy and safety of high-dose amino acid supplementation (AAS) in patients with gastrointestinal tumors undergoing surgical treatment.<br />Methods: This pragmatic, randomized, controlled, single-center, open-label, parallel-group AMIGITS trial was performed in a tertiary care teaching hospital. Patients with gastrointestinal tumors were randomly assigned to receive either AAS or standard care (SC). Amino acid targets were 2.0 g/kg per day in the AAS group and 1.2 g/kg per day in the SC group. The AAS group received additional amino acids intravenously, while the SC group received an iso-energetic 5% glucose intravenously.<br />Results: Overall, 407 patients (AAS group, 204; SC group, 203) were included in this study. During the intervention, the actual mean daily energy intake did not differ significantly between the AAS and SC groups (25.53 vs. 25.16 kcal/kg per day, P=0.493). However, the actual mean daily amino acid intake was significantly higher in the AAS group than that in the SC group (1.81 vs. 0.94 g/kg per day, P<0.001). The infection incidence during hospitalization and that within 30 days of surgery was significantly lower in the AAS group than that in the SC group (P=0.031 and P=0.024, respectively). The 30-day postoperative incidence of amino acid treatment-related adverse events and other complications did not significantly differ between the two groups. The postoperative hospital stay was significantly different between the two groups (P<0.001).<br />Conclusions: AAS was associated with a reduced infection incidence within 30 days of major surgery in patients with gastrointestinal tumors and can be a promising strategy.<br /> (Copyright © 2024 The Author(s).
