Insights
Chromium supplementation in parenteral nutrition (PN) improved glucose tolerance and calorie delivery in preterm infants. This essential nutrient is particularly beneficial for very low birth weight (VLBW) infants receiving PN therapy.
Area of Science:
- Neonatology
- Nutritional Science
- Endocrinology
Background:
- Early hyperglycemia is common in preterm infants on parenteral nutrition (PN).
- Chromium is known to enhance insulin action and improve glucose tolerance.
Purpose of the Study:
- To investigate if chromium supplementation in PN improves glucose tolerance and calorie delivery in neonates during their first week of life.
- To assess the impact of early chromium supplementation on very low birth weight (VLBW) infants.
Main Methods:
- A retrospective data analysis of neonates receiving PN from birth.
- Comparison of infants receiving chromium from day 1 (group B) versus days 5-7 (group A).
- Evaluation of glucose tolerance and PN calorie administration over the first week of life.
Main Results:
- Infants receiving chromium from day 1 (group B) demonstrated better glucose tolerance and received significantly more PN calories (74.8 kcal/kg/d vs 71.5 kcal/kg/d).
- This effect was more pronounced in very low birth weight (VLBW) infants, who received higher calorie delivery (76.5 kcal/kg/d vs 72.4 kcal/kg/d).
- Similar mean serum glucose concentrations were observed between groups.
Conclusions:
- Parenteral nutrition chromium supplementation enhances glucose tolerance and calorie delivery in infants, particularly VLBW infants.
- Chromium plays a crucial role in managing hyperglycemia risk in VLBW infants undergoing PN therapy.
- Early chromium administration supports improved nutritional outcomes in preterm infants.
Objectives:
Early hyperglycemia is prevalent in preterm infants receiving parenteral nutrition (PN) therapy. Chromium improves glucose tolerance by potentiating the action of insulin. Therefore, we hypothesized that supplementing PN with chromium would improve glucose tolerance and PN calorie delivery in infants during the first week of life.
Methods:
We collected data on neonates receiving PN initiated at birth with chromium (0.2 mcg/kg/d) started either on days 5-7 (group A) vs day 1 (group B) on PN and compared glucose tolerance and PN calorie administration over the first week of life.
Results:
For similar mean serum glucose concentrations between group A (n = 348) and B (n = 358) (107 ± 48 vs 111 ± 52 mg/dL, P = .3), infants in group B tolerated higher glucose infusion rates and received more PN calories during the first week of life: 8.4 ± 2 vs 8 ± 2 mg/kg/min (P < .001) and 74.8 ± 23 vs 71.5 ± 12 kcal/kg/d (P = .017), respectively. The difference in calories delivered was more pronounced among very low birth weight (VLBW) infants compared with infants >1500 g: 76.5 ± 14 vs 72.4 ± 11 kcal/kg/d (P = .009) and 73.8 ± 27 vs 70.3 ± 12 kcal/kg/d (P = .079), respectively.
Conclusions:
PN chromium supplementation resulted in better glucose tolerance and calorie delivery during the first week of life, especially in VLBW infants. This supports chromium's essential role in enhancing glucose tolerance during PN therapy in VLBW infants at risk for early hyperglycemia.
