Multifactorial Intervention in DM !Beyond a Glucose-centric ApproachThe ABCDE of Diabetes Maeve C. Durkan MBBS, FACP, Mmed.Ed Consultant in Diabetes, Endocrinology & Metabolism
A Multifactorial ApproachLessons from Steno 2 1,2 HR • Cardiovascular Death 0.43 • Cardiovascular Events 0.41 • Photocoagulation 0.48 • Not a GLUCOSE-CENTRIC strategy • But tight METABOLIC CONTROL
Multifactorial Approach • Not a GLUCOSE-CENTRIC strategy • But tight METABOLIC CONTROL • The EARLIER the better ….Imprinting • Additional effect with BP & Cholesterol
ABCDE • A : A1c, Aspirin • B : BP ,BMI • C : Cholesterol ,Complications • D : Diet • E : Exercise
DM shortens Lives • Diabetes (-)……………….Live forever ! • DM …………………………..Minus 6 years • DM & MI ………………….Minus 12 years
2/3 DM patients die from a CV event • Modifiable Risks • A ( A1c), B ( BP), C ( Chol) • Non Modifiable Risks • Age, gender, ethnic group
In 3 Pillars of CV Risk & Multifactorial Intervention Are all things equal ? A = B = C ?
50 year old • DM2 x 5 years • Coexistent hypertension ( on CoDiovan ) • Stable Angina . No CHF . • O/e : BMI 31, BP 145/90 • Cardiac & Respiratory exam normal • On Glucophage 1gm BD • HbA1c 7.8% ( 62 mmolar) , LFTs ALT 75,AST 45 • GFR 60 , Urine A/c ratio 3.5,
What Next after Metformin GRADE study : Worldwide Trial • Post metformin • Randomization to any one of each class • Except SGLT2 • Not powered as a CV trial
What did we get ?What so we want ? Past Options Now Limited choice Weight gain Hypoglycemia risk approaching target Β cell fatigue Loss durability Complications More choice Weight loss / neutrality Less hypoglycemia risk approaching targets Β cell preservation ! Durability Complications *
What Next ? • Sulphonylurea • Incretin • GLP 1 analogue ( daily/ weekly) • DPP IV • SGLT2 • TZD • Insulin
HbA1c targets • Individualized • < 7.0% : For all ? • < 6.5% : For Newly diagnosed ? • What about the newly diagnosed 75year old ?
Mortality & A1c Targets • ACCORD 10250 , High risk, Diabetes Duration 8-10years • VADT 1791, High risk, Diabetes Duration 11.5 years • ADVANCE 11,140 Moderate risk*, Diabetes Duration 8 yrs. • STENO 160, Low risk, Short Duration • UKPDS 3867, Low risk*, Newly diagnosed • DCCT 1441, Low risk, Diabetes Duration (1-15 years)
HbA1c & Glucose Early Intervention & Metabolic Memory is KEY

Sulphonylureas • Pros • Effective • Work & work quickly • Work well • 100% responders • HbA1c ↓ 1-2 % • Around for years • Cons • Hypoglycaemia • Weight gain • Beta cell fatigue • Durability • CV risk *
Driving Guidelines New European, UK & Irish Guidelines > 2 hypos / year ( On sulphonylureas ) Glucose records required on SU’s Insulin

TZDs: Pioglitazone (Actos) • Pros • Effective , more slowly • No hypoglycemia • HbA1c ↓ 1-2 % • Improved Lipids ( LDL*, Tg) • Target IR • Durability • CV benefit proven • NAFLD target ? • Cons • Weight gain (fluid) • Heart failure (NYC 111&IV) • Bone thinning/ Fractures • C/I with Dapagliflozin*
DPP IV Inhibitors Pros Cons Easily added to all, and/or insulin in & DM 2 Safe & effective in CKD Weight neutral HbA1c ↓(0.6-1%) No hypoglycemia Heart Failure TECOS rr 1.0 Pancreatitis ? Cancer ? NO EVIDENCE
1o Composite Cardiovascular Outcome* PP Analysis for Non-inferiority * CV death, nonfatal MI, nonfatal stroke, hospitalization for unstable angina Green JB et al. NEJM 2015; DOI: 10.1056/NEJMoa1501352
GLP1 Inhibitors Pros Cons Easily added to anything, and/or insulin in DM1* & 2 Safe & effective in CKD Concomitant weight loss SBP & DBP reduction HbA1c reduction No hypoglycemia 1/3 don’t respond Nausea Pancreatitis ? NO EVIDENCE No CV signal yet Lixizenatide Cancer ? NO EVIDENCE Needle
SGLT2 Inhibitors Pros Cons Easily added to anything, and/or insulin in DM1 & 2 Simple & dose response Concomitant weight loss SBP & DBP reduction HbA1c reduction No hypoglycemia UTI & Genital tract infections LDL (unclear mechanism) HDL (unclear mechanism) No CV signal yet Canvas Limited to CKD ( eGFR>45) Reversible shift in GFR
EMPA – REGEmpagliflozin ( NEJM Sept 16,2015) • Clear Findings • High risk Group • ↓Hospitalization for Heart failure • ↓Cardiac mortality
Potential Combinations • SGLT2 & DPPIV • SGLT2 & GLP 1 analogues
