Summary
No single treatment uniformly preserves beta-cell function in type 2 diabetes mellitus (T2DM). Lifestyle changes and early insulin therapy show promise, while certain medications maintain function during use, but long-term effects are unclear.
Area of Science:
- Endocrinology
- Metabolic Diseases
- Diabetes Research
Background:
- Progressive loss of beta-cell mass and function is central to type 2 diabetes mellitus (T2DM) worsening glycemic control.
- Increasing prevalence of T2DM necessitates strategies to slow disease progression and preserve beta-cell function.
Purpose of the Study:
- To review current data on preserving and improving beta-cell function in T2DM patients.
- To evaluate the efficacy of available strategies and agents for beta-cell preservation.
Main Methods:
- MEDLINE literature search (up to 2009) using keywords.
- Focused on studies of available agents' effects on beta-cell function in humans with T2DM.
Main Results:
- No universally effective treatment for beta-cell preservation identified.
- Lifestyle interventions and early intensive insulin therapy show some beta-cell preserving effects.
- Glucagon-like peptide-1 agonists, dipeptidyl-peptidase-4 inhibitors, and thiazolidinediones maintain or improve beta-cell function during treatment; long-term data are limited.
Conclusions:
- Continuous beta-cell decline drives T2DM progression, requiring new therapeutic approaches.
- Urgent need for strategies to delay progression, prevent T2DM, and induce remission.
- Future research should include comparative trials with washout periods for existing and novel beta-cell preserving agents.

01:24Type 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.
01:26Type 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...
01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
01:36Carbohydrate 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...

01:22Diabetes 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...

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.
