disability and mortality in older patients with type 2 diabetes:

There is now overwhelming evidence that the level and duration of

glycemia influences the development of diabetes-related

complications

Screening and diagnosisin the elderly

Page 12: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

Recommendations for screening and diagnosis in the

elderly

Clinical presentation of diabetes in old age is often asymptomatic and non-specific and clinical diagnosis may be delayed

In general, screening for and diagnosis of diabetes in older subjects should be in accordance with published international/national criteria and guidelines, and no age modified criteria are currently recognised

The prevalence and incidence rates of diabetes mellitus in elderly subjects (>65 years) may be underestimated when using only fasting plasma glucose.

Sinclair A, et al. Diabetes & Metabolism. 2011;37:S27-S38.

Page 13: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

The presence of isolated post-challenge hyperglycaemia (IPH) is common in older subjects and should alert the clinician to screen for cardiovascular disease and institute risk intervention strategies to minimise premature death.

In high-risk older subjects with a normal fasting glucose, and where an OGTT is not feasible, determination of HbA1c may be helpful in the diagnosis of diabetes. A value of HbA1c >6.5% may indicate the likely presence of diabetes

Page 14: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

Managing type 2 diabetes in the elderly

Special considerations

Clinicians who manage older people with diabetes require special skills if they wish to provide high-quality care

Their approach is influenced by a multitude of factors, such as the higher frequency of medical comorbidities, frailty and socioeconomic issues

Comprehensive geriatric assessment is a potentially important tool in ensuring that patients with diabetes receive a multi-professional assessment of their functional status and unmet needs.

Sinclair A. Diabetes Spectrum. 2006;19(4):229-33.

Page 15: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

Management goals in the elderly The overall goals of diabetes management in older adults

are similar to those in younger adults and include management of both hyperglycaemia and risk factors1

However, in frail, elderly patients with diabetes, avoidance of hypoglycaemia, hypotension, and drug interactions due to poly-pharmacy are of even greater concern than in younger patients with diabetes1,2.

In addition, management of coexisting medical conditions is important because it influences their ability to perform self-management2

Freedom from hyperglycaemic symptoms

Prevention of undesirable weight loss

Avoidance of hypoglycaemia and other adverse drug reactions

Estimation of cardiovascular risk as part of screening for and preventing vascular complications

Detection of cognitive impairment and depression and functional disabilities at an early stage

Achievement of a normal life expectancy for patients where possible

Protect against heart failure, renal dysfunctions , bone fractures and drug-drug interactions2

Acquisition of skills and knowledge to adapt to lifestyle changes

Encouragement of diabetes self-care

Page 17: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

Rationale for high-quality diabetes care in the

elderly

Recommendations:

Screening and early diagnosis may prevent progression of undetected vascular complications

Overall improved metabolic control will reduce cardiovascular risk

Improved screening for maculopathy and cataracts will reduce visual impairment and blind registrations

An integrated approach to management of peripheral vascular disease and foot disorders will reduce amputation rate

Sinclair A, et al. Diabetes & Metabolism. 2011;37:S27-S38.

Page 18: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

Associated problems affecting management in the

elderly… Poor Hepatic Glycogen Reserve:

Decreased stores related to poor nutrition and decreased appetite.

Cataract: Both age and DM contribute to its causation

Neuropathy: Autonomic neuropathy (postural hypotension, constipation, etc.)

Neuropathy, atherosclerosis of peripheral vessels and poor vision makes elderly more prone to foot problems and contribute to sexual impotence in a large number of elderly diabetics.

Why is the elderly diabetic patient

at high risk of hypoglycaemia?

Defective Counter-regulation or perception of symptoms

1.The effects of ageing on the responses to hypoglycaemia1

2.The effects of type 2 diabetes on the responses to hypoglycaemia2

3.The effects of type 2 diabetes and ageing on the counter-regulatory responses to hypoglycaemia3

• 1-Attention to hypoglycemic symptoms may be reduced by depression, cognitive dysfunction or other chronic conditions.

2-Many elderly patients have limited knowledge about the symptoms of hypoglycemia: knowledge of diabetes is essential for symptom recognition.

WHY?????

Page 27: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

1. The effects of ageing on the responses to hypoglycaemia:

There is defective perception of symptoms in the elderly 1

2. The effects of type 2 diabetes on the responses to hypoglycaemia:

Glucose counter-regulatory mechanisms may be abnormal in patients with Typ2 DM: impaired glucagon, growth hormone, cortisol, and perhaps epinephrine responses during hypoglycaemia could all contribute to a lack of compensatory increase in glucose production2

3. The effects of type 2 diabetes and ageing on the counter-regulatory responses to hypoglycaemia:

Impaired perception of hypoglycemia in older type 2 diabetes patients3

Treatment priority of the elderly: prevention of hypoglycaemia

The risks of tight glycaemic control may exceed the benefits in many elderly patients1

In elderly patients, who are frail and may have comorbidities limiting ability to self-management, tight glycaemic control is unlikely to benefit...

… and hypoglycaemia is associated with a wide variety of disabling consequences, including amputation, peripheral neuropathy, immobility, falls, stroke, and cognitive

change. The frequency of hypoglycaemia is high and is exacerbated by older people having

little knowledge about the signs and symptoms of hypoglycaemia.

The goal of minimising symptomatic hypoglycaemia, short-term geriatric syndromes and maximising quality of life should be the primary factors in individualising glycaemic targets

Glycemic targets for elderly with long-standing or more complicated disease should be less ambitious than for the younger, healthier individuals2

Page 40: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

The benefits of intensified glucose control require long-term adherence

Older patients or those with reduced life expectancy will therefore experience little benefit

Recent studies, which have used modelling techniques to estimate the impact of glycaemic control on life expectancy are enlightening in this respect. The UKPDS outcomes model estimated that intensified glucose control would increase quality-adjusted life years (QALY) by 0.27, or about 99 days.

Page 41: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

Treatment priority of the elderly: prevention of hypoglycaemia

The elderly patient with diabetes is often a frail patient1

Elderly people with diabetes are also at higher risk for hypoglycaemia and hypoglycaemia unawareness1,2

Hypoglycaemia is associated with many adverse consequences1

The available data suggest that the risks of tight glycaemic control (and the greatest risk is hypoglycaemia) exceed the benefits in many elderly patients1

Page 42: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

EASD/ADA recommendations for managing

hyperglycaemia in the elderly (2012)

Glycaemic targets for elderly with long-standing or more complicated disease should be less ambitious than for younger, healthier individuals

If lower targets cannot be achieved with simple interventions, an HbA1c of <7.5–8.0% may be acceptable, transitioning upward as age increases and capacity for self-care, cognitive, psychological and economic status, and support systems decline

In the aged, the choice of anti-hyperglycaemic agent should focus on drug safety, especially protecting against hypoglycaemia, heart failure, renal dysfunction, bone fractures, and drug–drug interactions. Strategies specifically minimising the risk of low blood glucose may be preferred

• CAUTION in the elderly

• Initial doses = HALF of usual dose

• Avoid glyburide

• Use gliclazide, gliclazide MR, glimepiride,

nateglinide or repaglinide instead

• CAUTION in the elderly

• Increased risk of fractures

• Increased risk of heart failure

• May use detemir or glargine instead of NPH or

human 30/70 for less hypos

• Premixed insulins and prefilled insulin pens

instead of mixing insulin to reduce dosing errors

• CAUTION with renal dysfunction

Diabetes in the Elderly Checklist

ASSESS for level of functional dependency (frailty)INDIVIDUALIZE glycemic targets based on the above (A1C

≤8.5% for frail elderly) but if otherwise healthy, use the same targets as younger people

AVOID hypoglycemia in cognitive impairmentSELECT antihyperglycemic therapy carefullyCaution with sulfonylureas or thiazolidinediones

Basal analogues instead of NPH or human 30/70 insulin

Premixed insulins instead of mixing insulins separately

GIVE regular diets instead of “diabetic diets” or nutritional formulas in nursing homes.

Canadian D A Guidelines 2015

Page 46: Ueda2016 workshop - diabetes in the elderly  - mesbah kamel

In the frail elderly, while avoiding symptomatic

hyperglycemia, glycemic targets should be an A1C of

≤8.5% and FPG or pre-prandial PG of

5.0-12.0 mmol/L, depending on the level of frailty.

In elderly people with cognitive impairment, strategies

should be employed to strictly avoid hypoglycemia,

which include the choice of antihyperglycemic

therapy and less stringent A1C target [Grade D, Consensus].

Elderly people with type 2 diabetes should perform

aerobic exercise and/or resistance training, if not

contraindicated, to improve glycemic control [Grade B,

Summary and conclusions Advancing age is a risk factor for the development of diabetes1

Elderly onset diabetes should be diagnosed as early as possible in accordance with national guidelines to avoid the progression of vascular complications, retinopathy and renal impairment2

Hypoglycaemia is a danger in elderly diabetes patients due to a higher level of hypoglycaemic unawareness and medication combinations in this population3

The presence of comorbidities presents unique challenges for the management of elderly type 2 diabetes patients3

Cognitive dysfunction, depression, risk of falls, frailty and other morbidities need to be addressed as part of comprehensive care3
