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.

Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Glucose Transporters01:27

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Glucose Absorption Into the Small Intestine01:26

Glucose Absorption Into the Small Intestine

Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

Hormones Regulating Blood Glucose01:16

Hormones Regulating Blood Glucose

Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Oral Hypoglycemic Agents: Glinides01:06

Oral Hypoglycemic Agents: Glinides

Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
