Study Notes

Pancreas Cells

The pancreas has cells that produce insulin, a hormone that regulates blood glucose levels.

LADA (Latent Autoimmune Diabetes in Adults)

Characterized by slow onset, generally misdiagnosed as type 2 diabetes.
Most prevalent form of adult-onset autoimmune diabetes.
Shares genetic features with both type 1 and type 2 diabetes.
LADA patients often have worse HbA1c levels than type 2 diabetes patients.

Factors Affecting HbA1c

Decreased HbA1c:
- Administration of erythropoietin, iron, vitamin B12: These substances can enhance the synthesis of red blood cells, leading to lower HbA1c levels.
- Hemoglobinopathies: These disorders can lead to variations in hemoglobin structure, ultimately affecting HbA1c values.
- Splenomegaly: An enlarged spleen can remove red blood cells prematurely, leading to lower HbA1c values.
- Rheumatoid arthritis: Some medications used to treat rheumatoid arthritis can affect HbA1c levels.
Decreased Erythrocyte Life Span: Conditions like chronic liver disease or certain types of anemia can reduce the lifespan of red blood cells, leading to lower HbA1c levels.
Increased HbA1c:
- Increased Erythrocyte Life Span: Conditions that prolong red blood cell lifespan can lead to higher HbA1c levels.
- High Blood Glucose Levels: Sustained high blood glucose levels lead to more glucose binding to hemoglobin, resulting in increased HbA1c.
