Study Notes
Type 1 Diabetes Mellitus (DM)
- Cellular-mediated beta-cell destruction leads to insulin deficiency, requiring insulin for survival.
- Accounts for 5-10% of DM cases.
- Also known as insulin-dependent diabetes.
- Prevalence in the USA is approximately 0.12% (around 340,000 individuals).
- Presents in childhood, early adulthood, or any stage of life.
- Typically symptomatic with a rapid onset in childhood, but can have a slower onset in older adults.
Other DM Types
- Genetic defects in beta-cell function or insulin action.
- Diseases of the pancreas, such as pancreatitis, neoplasia, or cystic fibrosis.
Insulin Therapy
- "1800 Rule" formula: 1800/TDI = # mg/dL of glucose lowering per 1 unit of rapid-acting insulin.
- Example: TDI 60 units → 1800/60 = 30 mg/dL reduction in blood glucose concentration per 1 unit of rapid-acting insulin.
- Switch to 5% dextrose with 0.45% sodium chloride when serum glucose is less than 200 mg/dL.
- Goal of insulin therapy is to stop ketosis, not to normalize glucose concentration.
Thyroid-Stimulating Hormone (TSH) and Coronary Heart Disease
- TSH > 10 mIU/L associated with increased risk of coronary heart disease.
- Treatment: Controversial, but may involve using levothyroxine and potentially reducing heart disease in younger patients (40-70 years old), although not in older patients (>70 years old).
