Type 2 Diabetes Status – 2007-2010 NHANES• Significant improvements from 1988 to 1994 (all P < 0.05)

• Statin use significantly increased between 1988–1994 (4.2%) and 2007–2010 (51.4%, P < 0.01)

• Younger individuals less likely to meet A1C and LDL goals

• Compared with non-Hispanic whites,

• Mexican Americans less likely to meet A1C and LDL goals (P < 0.03)

Adverse Outcomes in T1D Exchange - 2016-2018 Self Report from prior 3 months

Hypoglycemia • 6% had seizure or loss of

consciousness • 5% in <18 yrs; 10% in >50 yrs• Insulin pump use associated with

lower frequency (5% vs. 9%; p<0.001) • CGM use trended toward lower

frequency (5% vs. 7%; p=0.06) • CGM may have been prescribed or used

because offrequent severe hypoglycemia • Frequency of severe hypoglycemia not

associated with A1c level - high blood sugar not protective

DKA• 3% had DKA• Highest frequency (4%) in <26 yrs• Insulin pump use associated with less

DKA event than MDI (2% vs. 4%; p=0.002)

• CGM use fewer events than non-CGM users (1% vs. 3%; p=0.04)

• Higher A1c more likely to have DKA

AGP Data Display – Beyond A1C Metrics

Page 23: Technology in Diabetes Continuous Glucose …...2019/02/11  · Technology in Diabetes Continuous Glucose Monitors (CGM) and Insulin Pumps Francine R. Kaufman, M.D. Chief Medical Officer

Type 2 diabetes mellitus is characterised by insulin resistance and progressive β-cell failure, resulting in increasing hyperglycemia.1

Type 2 Diabetes

Treatment Challenges:

• Patients with advanced type 2 diabetes often require insulin • A1C targets often are not achieved when basal insulin is added 2,3

• Multiple Daily Injections (MDI), long-acting + rapid-acting insulin, are typically added when target are not achieved

• 30% of type 2 patients on MDI still do not achieve A1C targets – These patients have increased risk of hypoglycemia and weight gain.4

Limitations of MDI highlight the need for new treatment strategies in this subgroup of patients

Insulin pump therapy, multiple daily injections, andcardiovascular mortality in 18 168 people with type 1 diabetes: observational study

Steineck, I, et. al., for the Swedish National Diabetes RegisterBMJ 2015;350:h3234, doi: 10.1136/bmj.h3234

Objective: To investigate the long term effects of insulin pump therapy (CSII) on cardiovascular diseases (CVD) and mortality in people with type 1 diabetes

Design: Observational study from the Swedish National Diabetes Register, 2005-12

Study subjects: 18,168 type 1 diabetes subjects 2441 using CSII 15,727 using multiple daily insulin injections (MDI)

Main outcome measures: Hazard ratios estimated with Cox regression analysis

Follow-up: mean of 6.8 years; 114 135 person years.

Adjusted hazard ratios significantly lower for CSII 0.55 (95% confidence interval 0.36 to 0.83) for fatal

coronary heart disease 0.58 (0.40 to 0.85) for fatal CVD (coronary heart

disease or stroke) 0.73 (0.58 to 0.92) for all cause mortality

Hazard ratios lower, but not significant for CSII fatal or non-fatal coronary heart disease fatal or non-fatal CVD

WARNING: Medtronic performed an evaluation of the MiniMed 670G closed loop system and determined that it may not be safe for use in children under the age of 7 because of the way that the system is designed and the daily insulin requirements. Therefore, this device should not be used in anyone under the age of 7 years old. This device should also not be used in patients who require less than a total daily insulin does of 8 units per day because the device requires a minimum of 8 units per day to operate safely.

Do It Yourself - Improvements in A1C and Time-in-Range in DIY Closed-Loop (OpenAPS) UsersDANA M. LEWIS, RICHARD S. SWAIN andTHOMAS W. DONNER

• The most up-to-date list can be found here: https://loopkit.github.io/loopdocs/setup/requirements/pump/

• The Riley Link is the hardware that communicates between the pump, iPhone, and continuous glucose monitor. It is about the size of a tic-tac box and needs to be carried on you at all times. This seems like a fair trade for the ability to have an automated insulin delivery system.

• An Apple Developer Account is required to install the “Loop” application on your phone. It is not available in the current Apple store.

• As referenced above, a continuous glucose monitor is required. Loop can read CGM data directly from the pump meaning that Medtronic and Dexcom systems are compatible.

• Any specific questions on requirements can be found online: www.loopdocs.com

Effect of Artificial Pancreas Systems on Glycemic Control in Patients with Type 1 Diabetes: A Systematic Review and Meta-Analysis of Outpatient Randomized Controlled TrialsWeisman A, et al,Lancet Diabetes Endocrinol, May 19, 2017 http://dx.doi.org/10/1016/S2213-8587(17)30167-5

• Searched Medline, Embase, and the Cochrane Central Register of Controlled Trials for studies published from 1946, to Jan 1, 2017

• Excluded: non-English, pregnant women, in hospital, and using adjunct medications other than glucagon

• Primary outcome: mean difference % in target range (3·9–10 mmol/L or 3·9–8 mmol/L)

• 984 reports; after exclusions, 27 comparisons from 24 studies (23 crossover and one parallel design); 585 participants (219 in adult studies, 265 in paediatric studies, and 101 in combined studies)

• 5 dual-hormone (insulin and glucagon), 2 dual-hormone and single-hormone (insulin only), and 20 single- hormone

• Time in target -12·59% higher with artificial pancreas (95% CI 9·02–16·16; p<0·0001)

• Time in target -12·59% higher with artificial pancreas (95% CI 9·02–16·16; p<0·0001)

Interpretation: Artificial pancreas systems uniformly improved

glucose control in the outpatient settings, despite heterogeneous

clinical and technical factors.

Conclusions

• Diabetes Outcomes Still Suboptimal• New Metrics to Assess Performance – Beyond A1C• Technology – CGM and Insulin Pumps – Appear to Improve Outcomes

• Evidence to show efficacious and safe

• Penetration of Technology Still Very Low – Particularly in Type 2• The Promise of Insulin Automation

• The beginning of the journey
