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...
Type I Diabetes II: Pathophysiology01:26

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
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...

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
Carbohydrate Metabolism01:36

Carbohydrate Metabolism

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...

Area of Science:

  • Pediatric Endocrinology
  • Metabolic Disorders
  • Obesity Research

Background:

  • Childhood obesity epidemic is linked to increased adiposity-related complications.
  • Type 2 diabetes (T2D), previously an adult disease, now significantly affects adolescents, comprising 20-45% of new cases.
  • Progression to T2D involves stages like impaired fasting glucose and impaired glucose tolerance (prediabetes).

Purpose of the Study:

  • To investigate the pathogenesis of diabetes development in adolescents.
  • To elucidate the specific roles of insulin sensitivity and secretion defects in the natural history of T2D in this age group.
  • To describe the contribution of beta-cell function in the context of insulin resistance to T2D development in obese adolescents.

Main Methods:

  • Review of existing literature on T2D pathogenesis in obese youth.
  • Analysis of studies focusing on early defects in insulin sensitivity and secretion.
  • Examination of the interplay between beta-cell function and insulin resistance.

Main Results:

  • Insulin resistance and beta-cell dysfunction are key pathogenetic defects in obese youth progressing to T2D.
  • Beta-cell dysfunction plays a crucial role in the development of T2D in the context of adolescent insulin resistance.
  • Understanding these defects is vital for defining the natural history of T2D in this population.

Conclusions:

  • Beta-cell dysfunction is a critical factor in T2D development among obese adolescents, particularly in the presence of insulin resistance.
  • Further research is needed to fully clarify the mechanisms underlying T2D pathogenesis in this demographic.
  • Targeting beta-cell function may be a key strategy in managing and preventing T2D in obese youth.
