Bone fragility in type 1 diabetes and type 2 diabetes.

Summary of "Bone fragility in type 1 diabetes and type 2 diabetes."

Diabetes mellitus causes hyperglycemia due to resistance to insulin action in peripheral organs in addition to progressive loss of β-cell function, thus it is involved in the development and progression of diabetic microangiopathy(retinopathy, nephropathy, and neuropathy). In addition, abnormalities of bone metabolism is regarded as a chronic complication related to both type 1 diabetes and type 2 diabetes. Accumulating evidence suggests that type 1 diabetes patients had decreased bone mineral density(BMD)and the fracture risk in the femoral neck is markedly higher, when compared to non-diabetic patients. A lack of insulin level in the portal vein is associated with systemic deficiencies of Insulin-like growth factor-1(IGF-1), known as growth-promoting polypeptide essential for promoting growth and bone formation. Thus, loss of IGF-1 play a crucial role for the pathogenesis of reduced BMD in type 1 diabetes. In type 2 diabetes, despite high bone mineral density with obesity, several studies have shown that men and women with type 2 diabetes mellitus are at increased risk for bone fracture. In other words, unlike type 1 diabetes patients, an increase in the risk of fracture in type 2 diabetes is significantly related to compromised bone quality, the other factor of impaired bone strength.

Bone Disorders Associated with Diabetes Mellitus and Its Treatments.

Both type 1 and type 2 diabetes mellitus are associated with bone disorders, albeit via different mechanisms. Early studies in patients with type 1 diabetes suggested a 10-fold increase in the hip fra...

A ten-year prospective study of bone mineral density and bone turnover in males and females with type 1 diabetes.

In a previous community-based, cross-sectional study, males with type 1 diabetes had lower bone mineral density (BMD) than matched people without diabetes but females with type 1 diabetes had normal B...

Update on the impact of type 2 diabetes mellitus on bone metabolism and material properties.

The prevalence of type 2 diabetes mellitus (T2DM) is increasing worldwide, especially as a result of our aging society, high caloric intake and sedentary lifestyle. Besides the well-known complication...

The discovery of novel predictive biomarkers and early-stage pathophysiology for the transition from gestational diabetes to type 2 diabetes.

Gestational diabetes mellitus (GDM) affects up to 20% of pregnancies, and almost half of the women affected progress to type 2 diabetes later in life, making GDM the most significant risk factor for t...

Increased formations of neutrophil extracellular traps are associated with gut leakage in the patients with type 1 diabetes but not type 2 diabetes.

The aims of this study were to investigate the association of formation of neutrophil extracellular traps (NETs) with gut leakage not only in type 1 diabetes (T1D) but also in type 2 diabetes (T2D).

Medical and Biotech [MESH] Definitions

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

A severe type of hyperlipidemia, sometimes familial, that it is characterized by the elevation of both plasma CHYLOMICRONS and TRIGLYCERIDES contained in VERY-LOW-DENSITY LIPOPROTEINS. Type V hyperlipoproteinemia is often associated with DIABETES MELLITUS and is not caused by reduced LIPOPROTEIN LIPASE activity as in HYPERLIPOPROTEINEMIA TYPE I .

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).

A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
