Can We Prevent Complications? UKQOF Glucose Points Record of HbA1c in last 15months 3 HbA1c is 7.4 or less in the past 15 months 16 HbA1c is 10 or less in the past 15 months 11 BP HbA1c is 10 or less in the past 15 months 3 BP 145/85 or less in the past 15 months 17 Lipids Record of Cholesterol in last 15months 3 Cholesterol <5mmol in the past 15 months 6

Can We Prevent Complications? QOF & Glucose Not just about bringing down glucose… –No lower limit in QOF for HbA1c Safety first? –Avoiding Osmotic symptoms and Hypos Ensure regular and consistent meals. Consider withdrawal of treatment! Target HbA1c: ? ↑ 1% at %

Hypoglycaemia & Elderly Unawareness in old –↓counter-regulatory response –Take longer to recover. Misdiagnosis: –CVA, TIA –Fit –Confusion ?cause. Therefore:-. –Careful prescribing. –Ensure regular and consistent meals. –Consider withdrawal of treatment!

Benefits of Glucose Control: 2008 trials Intensive glucose control x3 –Target HbA1c % Little CVS benefit? –Already diagnosed DM –Over age 60 –Up to 6 years’ f.u. ↑Risk severe hypos ↑Risk Death (ACCORD) – Thanks to Gillian Hawthorne – BGS Spring Meeting 2009 intervention

Benefits of Glucose Control: 2008 trials Legacy Studies x2 Long Term benefit –New cases T2DM –Urine micro albumin Despite moderate control in long term –HbA1c: 8+% at 10+yrs Intensive glucose control x3 –Target HbA1c % Little CVS benefit? –Already diagnosed DM –Over age 60 –Up to 6 years’ f.u. ↑Risk severe hypos ↑Risk Death (ACCORD) intervention

New Drugs: Incretins Insulin release –Response to glucose Orally > I.V. Incretins –Secreted from small bowel –Stimulate beta cells to produce more insulin. Incretin effect

New Drugs: Incretins Incretins: new class of drugs: –GLP-1: exenatide Metabolised by DPP4 –DPP4- inhibitors Oral Gliptins Range of effects –↑Glucose dependent insulin secretion –↓glucagon secretion –Slow gastric emptying –↓ Food intake –↑ Β-cell mass in rats –↑ Insulin sensitivity –↑ Glucose disposal

Incretins in older people Exenatide NICE 3 rd line –Injection –HbA1c ↓1% –Weight ↓ kg Insulin ↑weight! Gliptins NICE 2 nd line –Tablet –HbA1c ↓1% –Weight ↓ kg Incretins for older patients –Theoretically: ↓ β cell mass= less effect –Not licensed monotherapy Exenatide –Benefit into 7 th decade Gliptins –Safe and well tolerated –Efficacy maintained: Glycaemia and Weight

Needs Dementia work up Consider depression Consider psychological impairment…

Conclusion: Diabetes in older people We have an epidemic –Old People & Diabetes Drugs –Old drugs Benefits- Legacy Risks of tight control –New drugs Glita-bones: Concerns Incretins… Just as effective in the old? Complications –Risks of treatment Orthostatic Hypotension Hypoglycaemia awareness –Dementia Lack of clinician awareness Dysglycaemia causal? Benefits from statins
