BACKGROUND AND OBJECTIVES: Several studies have shown that glutamine (Gln) may play an important role in energy metabolism, inflammatory reactions, and immune processes in patients with severe acute pancreatitis (SAP). Nevertheless, the results of individual randomized controlled trials (RCTs) on Gln nutrition support for SAP are contradictory. This systematic review and meta-analysis evaluated the clinical benefit of Gln-supported early enteral nutrition (G+EEN) in patients with SAP.

METHODS AND STUDY DESIGN: Cochrane Library, PubMed, Embase, CNKI, Wan Fang, and Chinese Biomedical Literature Database were searched for relevant studies published before December 2018. RCTs of G+EEN versus standard early enteral nutrition (EEN) for SAP were selected, with both started within 48 h of admission.

RESULTS: Seven clinical RCTs including a total of 433 patients (EEN group: 218 patients; G+EEN group: 215 patients) were included. Compared with EEN, G+EEN increased serum albumin (standard mean difference [SMD]=0.74; 95% confidence interval [CI], 0.33-1.15; p<0.01), reduced serum hypersensitive C-reactive protein (SMD=-1.62; 95% CI, -1.98 to -1.26; p<0.01) and risks of mortality risk (risk ratio= 0.38; 95% CI, 0.16-0.90; p=0.03) and multiple organ dysfunction syndrome (MODS)(risk ratio=0.37; 95% CI, 0.15-0.94; p<0.01), and shortened length of hospital stay (SMD=-1.19; 95% CI, -1.88 to 0.49; p<0.01); moreover, it did not significantly increase the incidence of infection-related complications, operative interventions, or APACHE II scores.

CONCLUSIONS: G+EEN is beneficial in SAP management.
