Insights

Continuous glucose monitoring in children with type 1 diabetes on insulin pumps showed irregular glucose levels and frequent hyperglycemia. The continuous glucose monitoring system (CGMS) was generally well tolerated, preserving hypoglycemia symptoms.

Area of Science:

  • Pediatric Endocrinology
  • Diabetes Technology
  • Metabolic Disorders

Background:

  • Insulin pump therapy is a key strategy for managing type 1 diabetes (T1D) in children and adolescents.
  • The goal of insulin pump therapy is to optimize glycemic control and minimize hypoglycemia.
  • Continuous glucose monitoring systems (CGMS) offer detailed insights into glucose fluctuations.

Purpose of the Study:

  • To evaluate interstitial glucose levels in pediatric T1D patients using insulin pumps.
  • To assess the frequency, duration, and symptoms of hypo- and hyperglycemia via CGMS.
  • To determine the tolerability of CGMS in this patient population.

Main Methods:

  • A cohort of thirteen children and adolescents with T1D on insulin pump therapy was studied.
  • Continuous glucose monitoring (CGMS) was employed for 72 hours to track interstitial glucose.
  • Patient demographics included age, diabetes duration, pump therapy duration, insulin dosage, and HbA1c levels.

Main Results:

  • Interstitial glucose concentrations averaged 187±40 mg/dl, indicating suboptimal glycemic control.
  • Hyperglycemia (above 180 mg/dl) was present for 47.3%±17.4% of the time.
  • Hypoglycemia (below 70 mg/dl) occurred 3.6%±5.6% of the time, with preserved adrenergic symptoms.

Conclusions:

  • Children and adolescents with T1D on insulin pumps exhibit irregular interstitial glucose levels and do not achieve normoglycemia.
  • Adrenergic symptoms of hypoglycemia remain intact in this population.
  • The CGMS was generally well tolerated by the pediatric patients, with one exception.

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...
Insulin: Dosing Regimen and Adverse Effects01:16

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...
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 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...
Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are co-secreted in...
Hypoglycemia01:26

Hypoglycemia

Hypoglycemia is a blood glucose level below 70 mg/dL. It commonly occurs in individuals using insulin or insulin-secreting drugs, but may also arise in non-diabetic conditions. People with type 1 diabetes are at the highest risk because they depend on exogenous insulin. People with type 2 diabetes are also at risk, especially when treated with insulin or medications such as sulfonylureas, which increase insulin release regardless of blood glucose levels. It develops when insulin levels exceed...
