Type 1 Diabetes: Important Treatment Themes

1 In addition to getting the A1c below 7% try1. In addition to getting the A1c below 7%, try to reduce the daily glucose fluctuations in your patients (hyper- and hypoglycemia)

2. The insulin regimen should mimic what happens in a non-diabetic state

3 Look out for other autoimmune conditions3. Look out for other autoimmune conditions (low thyroid levels, celiac)

11Clinical Strategies for Type 1

Determine the Correct Bolus Dosing (you should already have this part done on MDI)

Use what the patient was doing on MDI therapy (easiest way to start)

Carbohydrate counting (Insulin to CHO ratio) is helpful but not 100% necessary: Insulin to carbohydrate ratio: I:CHOU f ti f t i t t l Use of a correction factor is a great tool: Correction factor (CF) also called the insulin sensitivity factor (ISF)

Edelman SV. Taking control of your diabetes: a patient oriented book on diabetes. Fourth Edition Professional Communications Inc., Greenwich, CT. 544 pages, 2013.

Start with a ratio of 1:15 for insulin sensitive type 1 diabetics

Insulin to Carbohydrate Ratio Calculation: I:CHO

diabetics Start with a ratio of 1:10 for insulin resistant type 2

diabetics Formula: divide Total daily insulin dose into 500 Example: 34 year old male with type 1 diabetes

currently on 25 units of glargine (Lantus) every night and 20 to 25 units of insulin aspart (NovoLog)night and 20 to 25 units of insulin aspart (NovoLog)each day: 500/50=10 So the initial Insulin to carb ratio is 1:10

12Clinical Strategies for Type 1

Giving your patients a correction factor is a very practical tool whether they are on a pump or not

Correction Factor (CF) or Insulin Sensitivity Factor (ISP)

The CF is an estimate of how much the BS will drop with one unit of fast acting insulinThe CF usually 1:50 for insulin sensitive (<50u) patients and 1:25 for insulin resistant patients

The CF can be estimated by taking the total daily insulin dose and dividing it into 1800 (the 1800 rule)You also need to pick a target glucose level for the patient (between 100 and 150)

15Clinical Strategies for Type 1

Straightforward and Simple Ways to Start Insulin Pump Therapy

1. Get the patient adjusted as best as you can on a MDI1. Get the patient adjusted as best as you can on a MDI regimen with basal insulin (eg. U-100/300glargine [Lantus/Toujeo] or detemir [Levemir])2. Patient chooses a pump and the pump support people will help with insurance issues (they are good at this)

3. Determine the basal rate based on the total daily3. Determine the basal rate based on the total daily basal insulin dose (no change in boluses)

4. The pump trainer takes over and can help (0 to 100%) with the initial adjustments

A disruption in short acting insulin delivery due to a dislodged catheter, blockage, or an empty reservoir can result in a fairly rapid rise in glucose concentration

Disadvantages of Pump Therapy

rapid rise in glucose concentration◦ Severe hyperglycemia◦ Ketoacidosis

Cost of the insulin pumps◦ Pump costs approximately $3,500 to $5,000 (pay as you go

with the Omnipod)◦ Monthly cost of $30 to $40 due to batteries, infusion lines,

i d dh i tsyringes, and adhesive tape Minor skin irritation or infections at the insulin pump catheter

insertion site Very occasional abscess

Practical Clinical and Safety Tips for Patients Initiating Pramlintide in Type 1 and Type 2 Diabetes

Start with a low dose and titrate slowly to avoid nausea, which is the only side effect directly related towhich is the only side effect directly related to pramlintide

Take pramlintide with the main part of the meal Decrease the amount of fast-acting insulin by 30% to

50% when initiating pramlintide to avoid an insulin induced hypoglycemic reaction.

Use the extended bolus if on pump therapy Use the extended bolus if on pump therapy Be prepared to go through some interesting

psychological changes with regard to eating when initiating pramlintide
