- No flexibility:
- Required certain amount of calories a day
- Skipped meal - hypoglycemia (peak of NPH)
- Exercise - hypoglycemia (excessive glucose use)
- At night - hypoglycemia (peak of NPH)
- Overeating- hyperglycemia (not enough)
- Oversleeping- hyperglycemia (skipped dose)
|
|

|
- Poor control - HbA1C 10% and higher
- Fear of hypoglycemia - worsening of control
- Inability to exercise - poor fitness
- Early development of complications
- “OUT OF CONTROL”-Negative reinforcement
- “Don’t Do This, Don’t Do That”
- Mauriac syndrome - chronic insulin deficiency - stunted growth,
hepatomegaly

- Some causes of hypoglycemia in toddlers and preschoolers:
- Unpredictable food intake and physical activity.
- Imprecise administration of low doses of insulin.
- Frequent viral infections.
- Inability to convey the symptoms of low blood sugar.

- Rapid acting insulins:
Start in 10min
Peak in 1-2h Gone
in 3.5-4h
- Regular insulin: Starts in
30min Peaks in 3-4h Gone in 6-8h
|
|
23
|
- May be given just prior to the meal or after meal in babies
- Time of action match rise in sugar caused by most meals
- No action left at the time of next meal - no boluses buildups
- Less activity at bedtime - less night “low’s” and no need for bedtime
snack

- Lantus is a new type of long acting insulin that has no peaks
- Mimics physiological insulin (basal)
|
|
25
|
- Basal Insulin
- Insulin requirement to suppress hepatic glucose production between
meals
- Bolus Insulin (prandial)
- Insulin requirement to maintain normal glucose disposal after eating
- Insulin:CHO Ratio = 500/(total starting dose)
- Correction Factor = 1500/(total starting dose)
- Correction factor in young children = 1800/(total starting dose)

- Mean A1c 9.5% reduced to 7.9%.
- Severe hypoglycemic events 0.52 per month reduced to 0.09 per month.
- Increased parental confidence and independence.
- All refused to relinquish pump at completion of study.

- 195 patients between the ages of 13 and 17 in DCCT:
- Decreased worsening of retinopathy by 74% (p < 0.001).
- Decreased progression to proliferative or severe
non-proliferative retinopathy by 78% (p < 0.007).

|
- 195 patients between the ages of 13 and 17 in DCCT:
- Relative risk of hypoglycemia < 1 among prior intensive group.
- Prevalence of microalbuminuria 48% less.
- It is vital to achieve the best glycemic control early in the course in
diabetes during adolescence and childhood.
|
|

|
- “ Less than optimal glycemic control during the early years of diabetes
has a lasting detrimental effect on the development and progression of
complications, even after better glycemic control is established later
in the course of the disease.”

- 161 patients with type 1 diabetes:
- 26 ages 1 to 6
- 76 ages 7 to 11
- 59 ages 12 to 18
- 98% remained on CSII
- Reduced hypoglycemia (events/year)
- Age 1 to 6: 0.42 to 0.19
- Age 7 to 11: 0.33 to 0.22
- Age 12 to 18: 0.33 to 0.27

- TOO HARD/TIME CONSUMING
- I WAS UNINFORMED ON HOW TO USE THEM
- NOT FOR THE VERY YOUNG OR THE UNMOTIVATED
- ONLY AFTER HONEYMOON
- YOU HAVE TO TEST FOR ME TO PUT YOU ON PUMP
- YOU WILL SUFFER PSYCHOLOGICALLY

- Test the feasibility and efficacy of insulin pump therapy initiated
within the first month of diagnosis
- N=28 consecutive. mean age 12.1+ 6.2 years
- Range of start 1-30 days
- None discontinued after up to three year follow-up
- 2 sites Cornell Medical Center and Maimonides Medical Center
|
|
38
|
- Our hypothesis are:
- Patients on pump have better control of their blood glucose level
- Better control allows extension of the “honey moon” period
|
|
39
|
- Earlier aggressive glucose control leads to lower incidence of long-term
complications
- Insulin pump therapy resembles physiology more closely than multiple
daily injections
- Lower incidence of occult and overt serious and moderate hypoglycemia
- Would there be benefit to introducing pump therapy earlier rather than
waiting until further insulinopenia sets in?

- BMI-No significant gains or losses in BMI SD over study time
- All patients were “self-sufficient” within 3 months
|
|
46
|
- Starting patients on insulin pump therapy is a viable option at or soon
after diagnosis
- Further studies need to be performed to see if quality of life and long
term complications are affected
- Despite the labor intensivity of this approach the benefits were clear
and patients opted to remain on pump therapy after treatment
- Apparent prolongation of the honeymoon
|
|
47
|
- Typical Criteria
- Only motivated patients
- only patients who showed good compliance on previous regimen
- Adults and children > 6y old
- My Criteria
- Any patient who is willing to start and has abilities to learn
- May improve compliance
- Any age adults and children of any age (independent users 7-80 y old)
- Particularly “non-compliant” patients

|
- Improved control - more physiological basal rates (“dawn phenomenon”
match), different boluses for food, less absorption variability
- Less hypoglycemia
- More flexible lifestyle and possibility to exercise
- Precise dosing - 0.1u - 0.025u
increments for basal rate and boluses
- Less injections - improved quality of life
- Less possibility of overdose

|
- 200,000 users (adults and kids in the US). 10,000 are adults with type 2
diabetes
- ~ 20,000 children using pump therapy
- 10% of all children with diabetes
- Penetration as high as 90% in some pediatric clinics (ours)
- Increasing use in younger children (as young as 10 months)
- Current outcomes indicate CSII is safe and effective in children
- Increasing acceptance likely due to DCCT findings as well as the
introduction of smaller, safer insulin pumps
- There are approximately 400,000 insulin pump users worldwide
|
|
59
|
- Give a pen with the pump
- Instruct that any time the patient feels nauseated or has abdominal pain
-- change the site
- Blood sugar is greater than 250 mg/dl
- Take correction dose
- Check for ketones
- Recheck in 60 minutes
- If coming down, leave alone
- If not, take a shot and change the site
|
|

|
- Pump therapy is an intensive process for pediatric patients and their
families and the diabetes education team.
- Successful pumpers are motivated and willing to maintain follow-up,
carbohydrate count, and check blood glucose frequently.
- Benefits of pump therapy for pediatric patients include: improved lifestyle, decrease in
hypoglycemia, accurate dosing , ability to review history to see if
doses were actually given.
|
|
61
|
- Children with diabetes should be intensively treated to avoid short and
long term complications
- Insulin pumps can provide better control and less hypoglycemia than MDI
- With good support and a standardized process, insulin pump therapy can
help to improve diabetes management in children
- Insulin pump therapy should be the only form of therapy offered to
children with diabetes
