Insights

Obese children with glucose intolerance (GI) show reduced insulin secretion, not increased insulin resistance (IR), despite similar clinical features. This suggests impaired insulin production contributes to GI in pediatric obesity.

Area of Science:

  • Pediatric Endocrinology
  • Metabolic Disorders
  • Obesity Research

Context:

  • Childhood obesity is rising, increasing the risk of Type 2 Diabetes Mellitus.
  • Glucose intolerance (GI) is a precursor to Type 2 Diabetes, following a period of insulin resistance (IR).
  • Understanding metabolic characteristics in obese children is crucial for early intervention.

Purpose:

  • To characterize the clinical and metabolic profiles of obese children based on their glucose tolerance status.
  • To investigate differences in insulin resistance and secretion between obese children with and without GI.

Summary:

  • A study of 52 obese children (ages 8-17) assessed glucose tolerance and insulin dynamics using an oral glucose tolerance test and HOMA index.
  • Children with GI (11.5%) exhibited similar clinical features and HOMA scores to those with normal glucose tolerance.
  • However, children with GI had lower 30-minute insulin levels, a reduced Insulinogenic Index, and higher total and LDL cholesterol.

Impact:

  • Identifies decreased insulin secretion as a key factor in the development of glucose intolerance in severely obese children with IR.
  • Highlights the need for monitoring lipid profiles in obese children.
  • Informs potential therapeutic strategies targeting insulin secretion in pediatric metabolic health.

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:
Diabetes: Symptoms, Diagnosis, and Complications01:15

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...
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 'exit' via the...
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...
Hyperglycemia01:29

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
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...
