Study Notes
Diabetes Mellitus
- Diabetes mellitus is a metabolic disorder of multiple etiologies, characterized by chronic hyperglycemia due to defects in insulin action or insulin secretion.
- People with type 1 diabetes are at increased risk for other autoimmune diseases, such as thyroid disease, celiac disease, and pernicious anemia (vitamin B12 deficiency).
Criteria for Testing for T2DM in Children & Adolescents
- Overweight plus any 2 of the following:
- Family history of type 2 diabetes in 1st or 2nd degree relatives
- Race/ethnicity
- Signs of insulin resistance or conditions associated with insulin resistance
- Maternal history of diabetes or GDM
Strategies of DM Management
- Health education is key for better compliance and patient outcomes.
- Patient education should include:
- Understanding of the disease
- Alarming clinical manifestations of hypo or hyperglycemia
- Complications of the disease
- Information about medical treatment and types of insulin
- Instructions on insulin storage and injection places
- Fixing times for insulin and meals, and following dietary recommendations are important.
- Remind patients to perform self-monitoring of blood glucose (SMBG) for better optimization of blood glucose.
Anti-Diabetic Drugs
- Start monotherapy if HbA1c is less than 1.5% above target HbA1c.
- Start combination therapy if HbA1c is more than 1.5-2% above target.
- Consider metformin as the backbone of treatment for diabetes, unless contraindicated or not tolerated.
- Metformin dosing:
- Starting dose: 500mg with main meals, either once or twice
- Optimal dose: 1000mg, twice daily
- Maximum dose: 2550mg (up to 3000mg in some guidelines)
Sulphonylurea
- Classified into 3 generations:
- 1st generation: Gibenclamide (conventional sulphonylurea)
- 2nd generation: Gliclazide (less risk of hypoglycemia and weight gain)
- 3rd generation: Glimepride (more efficacy and less hypoglycemia)
- Take care of risk of hypoglycemia and weight gain.
- Glibenclamide:
- Starting dose: 2.5-5mg before breakfast, can be increased to twice daily dose
- Maximum dose: 20mg
- Gliclazide:
- Starting dose: 30mg before breakfast, can be increased by 30mg on a weekly basis
- Maximum dose: 120mg
TZDs
- One of the most potent insulin sensitizers, acting on PPAR gamma receptors in liver and adipose tissue.
- Can be used in treatment of fatty liver and polycystic ovary.
- Take care of cardiovascular risk:
- Avoid in heart failure
- No renal dose adjustment, but avoid in renal impairment due to risk of fluid retention
DDP4 Inhibitors
- Leader group in management of type 2 diabetes.
- Controls blood glucose in glucose-dependent manner with less incidence of hypoglycemia and weight neutral effect.
- Examples: Sitagliptin, Vildagliptin, Linagliptin, Saxagliptin, Alogliptin
SGLT2 Inhibitors
- One of the promising groups in treatment of type 2 diabetes.
- Act by inhibiting 90% of glucose reabsorption in the first segment of the proximal convoluted tubule.
- Examples: Dapagliflozin, Empagliflozin
- Has a proven cardioprotective effect, as seen in the EMPA-REG trial.
- Complications:
- Urinary tract infections due to glucosuric effect
- Mycotic vaginal infection
- Euglycemic ketoacidosis if used off-label in type 1 patients or started at high dose
GLP1 Receptor Agonist
- One of the promising drugs in diabetes.
- Controls blood glucose in glucose-dependent manner with less incidence of hypoglycemia and decreases satiety, leading to weight loss.
- Examples: Liraglutide, Dulaglutide, Semaglutide
Insulin Therapy
- Indications:
- Type 1 patients (IDDM)
- Uncontrolled type 2 patients on two or more oral drugs at maximum dose, with HbA1c > 8.5%
- Recently diagnosed type 2 patients with HbA1c > 10% or blood glucose > 300mg, especially if there is catabolic state or associated increased triglycerides level
- At hospital admission
- Insulin types:
- Premixed insulin
- Basal bolus regimen (MDI)
- Starting dose of insulin: 0.5 unit per kg per day, divided into two-thirds as morning dose and one-third as night dose.
- Example: 80kg type 2 patient, starting premixed insulin at 40 units daily, divided into 25 units before breakfast and 15 units before dinner.
