Glutamine supplementation for preventing morbidity in preterm infants

Area of Science:

• Neonatal Nutrition
• Pediatric Critical Care
• Amino Acid Metabolism

Background:

• Glutamine is a key fuel for rapidly dividing cells.
• Its role in critical illness is under investigation, primarily in adults and animal models.
• Limited data exists on glutamine's effects in infants, especially preterm babies.

Purpose of the Study:

• To evaluate the impact of glutamine supplementation on morbidity and weight gain in preterm infants.
• To synthesize evidence from randomized controlled trials on glutamine's efficacy in neonates.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials.
• Searches conducted in Medline and Embase databases.
• Included trials compared glutamine supplementation versus no supplementation in preterm infants.

Main Results:

• Three trials met inclusion criteria; meta-analysis of blood culture data showed no significant difference (RR = 0.73).
• No significant differences were found in time to full enteral nutrition, rate of weight gain, or duration of hospital stay.
• Pooled data from two studies indicated no statistically significant benefits from glutamine supplementation.

Conclusions:

• Current evidence does not support routine parenteral or enteral glutamine supplementation in preterm infants.
• A large randomized controlled trial is recommended to investigate glutamine's potential to improve gut integrity and reduce sepsis.
