Kang K, Shu XL, Zhang YS, Liu XL, Zhao J - Chin. Med. J. (2015)

Bottom Line: Thirteen RCTs, involving 1034 patients, were included in the meta-analysis.Meanwhile, it was more significant in decreasing the incidence of infectious complications (RR: 0.67; 95% CI: 0.50-0.90; P < 0.05) and shortening the length of hospital stay (MD: -1.72; 95% CI: -3.31--0.13; P < 0.05).Glutamine enriched nutrition support was superior in improving immune function, reducing the incidence of infectious complications and shortening the length of hospital stay, playing an important role in the rehabilitation of surgical GI cancer patients.

ABSTRACT

Background: Associations between glutamine (Gln) enriched nutrition support and surgical patients with gastrointestinal (GI) tumor remain controversy. The purpose of this meta-analysis was to assess the effect of Gln enriched nutrition support on surgical patients with GI tumor in term of relevant biochemical indices, immune indices, and clinical outcomes.

Methods: Six databases were systematically searched to find eligible randomized controlled trials (RCTs) from 1966 to May 2014. When estimated the analysis indexes, the relative risk (RR) was used as the effect size of the categorical variable, while the weighted mean difference (MD) was used as the effect size of a continuous variable. Meta-analysis was conducted with Rev Man 5.2.

Results: Thirteen RCTs, involving 1034 patients, were included in the meta-analysis. The analysis showed that Gln enriched nutrition support was more effective in increasing serum albumin (MD: 0.10; 95% confidence interval [CI]: 0.02-0.18; P < 0.05), serum prealbumin (MD: 1.98; 95% CI: 1.40-2.55; P < 0.05) and serum transferring (MD: 0.35; 95% CI: 0.12-0.57; P < 0.05), concentration of IgG (MD: 1.26; 95% CI: 0.90-1.63; P < 0.05), IgM (MD: 0.18; 95% CI: 0.11-0.25; P < 0.05), IgA (MD: 0.22; 95% CI: 0.10-0.33; P < 0.05), CD3 + (MD: 3.71; 95% CI: 2.57-4.85; P < 0.05) and CD4/CD8 ratio (MD: 0.27; 95% CI: 0.12-0.42; P < 0.05). Meanwhile, it was more significant in decreasing the incidence of infectious complications (RR: 0.67; 95% CI: 0.50-0.90; P < 0.05) and shortening the length of hospital stay (MD: -1.72; 95% CI: -3.31--0.13; P < 0.05).

Conclusions: Glutamine enriched nutrition support was superior in improving immune function, reducing the incidence of infectious complications and shortening the length of hospital stay, playing an important role in the rehabilitation of surgical GI cancer patients.

Mentions: In the analysis for concentration of TNF-α (pg/ml), 101 patients in three studies[151621] were extracted. The heterogeneity among them was significant (I2 = 89%; P < 0.05; Chi-square = 17.77), thus we used a random-effects model to analyze the data. The change of concentration of TNF-α was not statistically significant (MD: −7.34; 95% CI: −18.15–3.47; P > 0.05) [Figure 6].
