Diabetes Introduction

Why we need to consider the impact

How large is the problem? How can you understand what it is

to be a person with diabetes?

04/19/23 3

Diabetes Mellitus

Type 1 Rare—affecting only 1

in 250 (1 in 400 kids) 15,000 new cases per

year Low rates in Black and

Asian populations

Type 2 Common Probably 25 million

cases in the US. 1/3 cases undiagnosed

Projected prevalence of 11% WOW! Over age 65, 27% with DM

Cost: $ 218 billion in 2007

04/19/23 4

Diabetes MellitusType 1 and Mortality

Mortality rates for people with DM Type 1 are 5 to 7 times the general population

More than 15% of people with DM type 1 will die by age 40

They die of DKA, of renal failure, of cardiovascular disease

Life expectancy is reduced by 15 years

Competence Questions

        a.  desire for a pump and insulin use        b.  diabetes type 1 if on Medicare         c.  diabetes type 2 for many

commercial insurances

        d.  Insulin use  

Competence Questions

        b. Bromocriptine, linagliptin, saxagliptin

        c. Carbohydrate counting, continuous glucose monitoring, insulin

pumps

Competence Questions

3.  Continuous glucose monitoring can be used

        a. only with a pump        b. only with multidose injection insulin

therapy        c. must be used daily         d.  costs about $35 per week on-going

costs

Take Home Goals

Think like a pancreas

Give enough insulin

Get and give loads of education

Intensive Therapy

Decreases risks of microvascular disease Retinopathy 75% reduction Nephropathy 50% reduction Neuropathy 60% reduction

Goal is to achieve normoglycemia Measure BS frequently Increases risk of hypoglycemia

Insulin Regimens

Twice a day mixed insulin Once daily long acting with lispro or

regular with each meal Twice daily intermediate or long acting

insulin with lispro or regular at each meal Once a day long acting insulin with

lispro/aspart/glulisine at each meal CSII is continuous subcutaneous insulin

infusion this is insulin pump

Insulin Pen or Syringe Injections with MDI can approach the Ideal

Insulin pens are very handy

Use ONLY on one person

04/19/23 21

CSII or Insulin Pump

Programmed basal rate of insulin and calculated boluses with carbohydrate intake

Place needle or catheter subcutaneously every 3 days

Short or rapid insulin analog only Special attention to prevent DKA

Continuous Monitoring

04/19/23 30

Patient versions of Continuous Monitoring or CGM

Dexcom 7Medtronic Real time or Guardian

04/19/23 31

Two Versions of CGM

Professional

1. If we need more information, we can do the “Holter Monitor” of glucose

2. Several days of glucose data with meals and insulin data from the patient

Personal

1. The patient sees the glucose data as it is produced

2. Can be used continuously or intermittently

3. Cost about $35 cash per usage

Transplants

Whole pancreas transplants usually along with kidney

Technical difficulties with islet only transplants

Autotransplantation of islets– only if we take out your pancreas for NON diabetes reason

Future ?

Artificial pancreas

Better data collection

Easier diagnosis Test genes

to see who might get disease

Your glucose sensor reminds you that you forgot to take insulin

Scan the food for auto carb calculation

Dr. Oates is on the beach with her computer and your company pays her NOT to see you

How Incretins Work1-3

IntestineIntestine

Food triggers the release of incretin hormones (GLP-1 and GIP) by the intestines into the blood

Blood

The body makes DPP-4, an enzyme that rapidly breaks down GLP-1 and GIP

Mechanism of DPP-4 Inhibitors

DPP-4

DPP-4 inhibitorsBlock the action of DPP-4DPP-4 rapidly breaks down GLP-1 and GIP

Hinnen D, et al. J Am Board Fam Med. 2006;19:612-620.

04/19/23 58

Mechanism of GLP-1 Receptor Agonists1,2

GLP-1 receptor agonists directly activate the GLP-1 receptor resulting in effects similar to natural GLP-1 but are resistant to breakdown by DPP-4

Reduce appetite

Slow down how quickly food leaves stomach and make patients feel “full”

Help the pancreas make more insulin when blood sugar is high

Help keep the liver from releasing too much sugar into the blood
