Pathophysiology of Diabetes

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...

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...

Hormonal Regulation

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Type II Diabetes II: Pathophysiology

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.

Summary

Pre-eclampsia (PE) is linked to an imbalance of adiponectin and leptin. Lower adiponectin and higher leptin levels may contribute to PE development and severity.

Area of Science:

Endocrinology
Obstetrics
Reproductive Medicine

Background:

Pre-eclampsia (PE) is a significant pregnancy complication.
Adipocytokines, including adiponectin and leptin, play roles in metabolic regulation.
Their specific involvement in PE pathogenesis requires further elucidation.

Purpose of the Study:

To investigate the role of adiponectin and leptin in pre-eclampsia.
To analyze the relationship between plasma adiponectin and leptin levels in PE patients.

Main Methods:

Study included 73 pregnant women: 53 with PE (mild and severe) and 20 healthy controls.
Plasma adiponectin and leptin levels were measured using enzyme-linked immunosorbent assay.
Correlation and balance between adiponectin and leptin were evaluated.

Main Results:

Adiponectin levels were significantly lower in women with mild or severe PE compared to controls.
Leptin levels were significantly higher in women with mild or severe PE.
A negative correlation was observed between adiponectin and leptin in PE patients, with a lower adiponectin/leptin ratio.

Conclusions:

An imbalance between adiponectin and leptin exists in pre-eclampsia.
Reduced adiponectin and elevated leptin may contribute to PE pathogenesis.
These adipocytokine alterations are associated with disease severity.
