Type 1 Diabetes - Part 1

JBW - January 2003

• 9 year old boy, otherwise healthy• Many classmates had flu• Onset of nausea, vomiting, lethargy• Call to local healthcare:

–Asked about hydration status, time of last urination

• Next morning, JBW found dead in bed

Outline: Part 1

• Changing epidemiology of diabetes in youth– Type 1 vs type 2– Epidemic rates of type 1 diabetes– Younger age of onset of type 1 diabetes

• Glycemic control– Adolescents and the DCCT– Factors related to glycemic control– A1c guidelines and A1c outcomes in T1D

• Cases

Outline: Part 2

• Other challenges– Hypoglycemia as a barrier to A1c goals– Family impact of T1D

• Changing glycemic outcomes– BG monitoring– Insulin pump use and bolus dosing

• Other opportunities– Continuous glucose monitoring

• Cases

Epidemiology - 1• 15,000 youth/yr in USA & 70,000 youth/yr

worldwide are diagnosed with T1D• 3,700 youth/yr in USA are diagnosed with

T2D; ??? numbers/yr worldwide with T2D• T1D occurs equally among males and

females; T2D occurs 1.6x more often in females than males

• T1D is more common in whites than non-whites; T2D occurs more often in racial/ethnic minorities

Epidemiology - 2

• ~75% of T1D is diagnosed in people <18 years old; majority of people with T1D are adults

• Majority of T2D is diagnosed in adults• 215,000 total youth in USA and >500,000

youth worldwide <20 years old with diabetes in 2010

• >371 million persons worldwide have diabetes; numbers will be >550 million by 2030

Diabetes in Youth & Adults: Epidemiological Trends

• Epidemic of Childhood Obesity– 1 out 3 children is overweight or obese– Increasing occurrence of type 2 diabetes in youth– 1 out of 3 children born in 2000 will develop diabetes

• Type 1 Diabetes in Youth– Increasing incidence / prevalence during 20th and 21st C– Shift towards younger age of onset

• Diabetes is increasing worldwide, with epidemic increases of type 2 diabetes in adults; rates of new onset type 1 diabetes in adults unclear

Increasing Incidence of T1D in 0-17 year old Youth in Colorado

IR of T1D increased 1.6-fold in Colorado

1978 to 2004: 14.8 to 23.9/100,000/year

• Numbers of youth with diabetes are expected to rise substantially by 2050

• Estimates based up stable annual IR of T1D and T2D, there will be ~25% more youth with T1D and ~50% more youth with T2D by 2050

• Estimates based upon the current annual IR increases of 2.3% in Colorado, USA (Vs 3.9% in Europe), there will be 300% more youth with T1D and 400% more youth with T2D by 2050AND, IN TURN, THERE WILL BE MORE CASES OF DKA

Nov 2, 2012

Annual death rates in USA from diabetes per 1,000,000 youths

Death rates mainly from acute complications: hypoglycemia and DKA.Overall decline in death rates by 61% from 1968-2009.

After initial decline, death rate increased from 1984-2009 in 10-19 y/o.

Discussion Point:Factors related to onset of T1D

• In your practice, how do you explain new onset type 1 diabetes to families? What factors related to type 1 diabetes onset do you discuss with families?

DCCT: Adolescents Vs Adults

• significantly higher A1c’s: intensive- 8.1 vs 7.1%conventional- 9.8 vs 9.0%

• significantly more hypoglycemia:intensive- 86 vs 57/100-pt-yrsconventional- 28 vs 17/100-pt-yrs

• had significantly more DKA than adults:intensive- 2.8 vs 1.8/100-pt-yrsconventional- 4.7 vs 1.3/100-pt-yrs

Intensive insulin therapy:• Improved A1c compared with conventional therapy• Reduced risk of diabetic eye disease by 53-70% (P<.05)• Reduced risk of diabetic kidney disease by 55% (P<.05)

Intensive insulin therapy required:• Multi-disciplinary team management• Education and support for insulin dosing, diet, exercise• Frequent blood glucose monitoring• Regular follow-up care

Risk of Hyperglycemia

• Due to intensity of exposure

Case #1: Overview

• A 14 year old boy with high A1c treated with a continuous subcutaneous insulin infusion (insulin pump)– He has had diabetes for 5 years and

been on the pump for 3 years– A1c was relatively stable at 7.5% until

the past 1 ½ years, when it started rising to 9%

Question #1

• What would you do?

A: Prescribe more insulin

B: Take him off the pump

C: Talk to him about complications

Case #1: Issues to Consider

• Division of diabetes-related responsibility

• What is going on in other areas of patient’s life?

• Family conflict (general and diabetes-specific)

• How does he feel about his A1c?• Is this a safety issue? Does he need to

be taken off pump?

Discussion Point: Obstacles to Achieving

Management and Metabolic Goals:

• At your tables, identify 3 obstacles that you think are responsible for making it difficult for patients and their families to achieve optimal metabolic goals.

– Have a 3 minute discussion about this at each of your tables.

Adherence and Family Behavior in Children with Type 1 DM

1) Advances in DM treatment (“intensive therapy”)a) improves metabolic control, prevents complicationsb) increases the importance of adherencec) places increased demands on youth and their families

2) family conflict (DM and general) correlate with treatment adherence

3) developmentally appropriate parental involvement leads to adherence and metabolic control

Case #3: Overview

• A 17 year old girl with 2 hospitalizations for DKA in the past year– T1D since age 10– Relatively good control of diabetes until

age 15, then A1c up to 11% – She does all diabetes management on own

– does not want parents involved

Question #3

• What would you do?A: Tell the parents to get more involved in her care

B: Tell the parents they should absolutely NOT have involvement in her care – she is almost an adult

C: Try to find out more about why this is happening

Case #3: Issues to Consider

• What is going on in other areas of her life?• Anything new in past year?• Possible eating disorder?• How does she feel about her diabetes?• Why is she omitting insulin? • How does the family interact around

diabetes?

• ~30% of females teens with T1D had DEBs or EDs• ~30% used insulin restriction or omission for weight loss• Those with DEB/EDs had higher A1c by ~2%• During 4 years of F/U, those with DEB/EDs had 3x the

risk of retinopathy and 2x the risk of microalbuminuria

Opportunities with CGM Use

Continuous data, revealing rate and direction of change

Improve diabetes management and self-efficacy Immediate feedback regarding insulin, diet,

exercise, stress Alarms and trend data can help prevent

hypo- and hyper-glycemia Retrospective data allows refinement of Rx

Reduce anxiety about hypoglycemia Reduce family conflict due to better control, or

greater awareness that BG numbers do not always reflect behavior in a predictable way

Challenges of CGM Use Increase anxiety and/or depressive symptoms

Too much information/overwhelming? CGM leads to excessive focus on numbers? Increase awareness of out-of-range values Disagreement between CGM and traditional

BGM values Burden associated with insertion, calibration, tape,

alarms Increase family conflict (e.g., parental blame if

awareness of out-of-range values increases)

With negative impact of CGM less CGM usage

Glucose Monitoring: SMBG & CGM

SMBG CGM

Challenges of CGM Usefor Families and Youth with

T1D• Parents seek improved approaches to care;

parents provide consent, youth “go along for the ride”

• Youth expect devices to make management easier; unrealistic expectations for “cure” with artificial pancreas

• Parents of younger children remain involved, parents of adolescents disengage with increased adolescent autonomy and need for privacy (sensors worn on body = personal invasion)

• Parents of younger children often fear low BGs more than high BGs

• Children do not look at receiver; adolescents often ignore “nuisance” alarms

Opportunities& Ongoing Challenges

• In the post-DCCT era, more pediatric patients with T1DM receive intensive diabetes management leading to improved glycemic control

• There remains a significant gap between current glycemic outcomes and glycemic targets in pediatric patients today

• Present: education, technologies, and multi-disciplinary support to reduce the gap

• Future: CGM and closing the loop
