Diabetes & Chronicdisease
Diabetes
Coronary heart disease in diabetes
• It is more common and occurs earlier than in people eithout diabetes
• Women lose gender protection
• Myocardial infarction may be painless(silent)
• Albuminuria increases risk of vascular event
Compared to people without diabetes, people with type 2 diabetes have
• The same risk of heart attack as those who have already had a heart attack
• Two-to three-ford higher risk of heart failure
Sudden death occur more commonly in people with diabetes than among peers without diabetes of the same age
Myocardial infarction and diabetes
People with diabetes have poor prognosis even after adjustments for infarct size and risk factors
Prevention
Research shows the benefits of reducing the modifiable risk factors for atherosclerosis
Modifiable risk factors are
• Dyslipidaemia (especially LDL-C)
• Smoking and exposure to tobacco smoke
• High blood pressure
• Diabetes
• Central obesity
• Physical inactivity
Activity
TJ is newly diagnosed with diabetes. He smokes one pack of cigarettes. He smokes one pack of cigarettes a day and does not do any exercise. His blood pressure is 150/95 and his BMI is 30.
• What are his risk factors?
• What else should you assess?
• How will you approach him regarding his risk factors?
Retinopathy
Objectives
After completing this module participants will be able to
• Define retinopathy
• Discuss the risk factors for retinopathy
• Describe preventive strategies for retinopathy
• Explain the benefits and possible side effects of laser treatment to a person with diabetes
Eye diseases in people with diabetes
• Diabetic Retinopathy
• Diabetic Cataract
• Cranial nerve palsies leading to diplopia
• Diabetic papillopathy
Transient changes in vision
• Cause—changes in blood glucose levels cause osmotic changes in the lens of the eye
• As a result, visual acuity can increase or decrease
• This change is not permanent and will resolve when blood glucose levels stabilize
Retinopathy in people with diabetes
• A silent complication with no initial symptoms
• When symptoms occur, treatment is more complicated
• Screening for retinopathy is of the utmost importance
When to screen for retinopathy
type 1 diabetes: within 5 years of diagnosis
type 2 diabetes: at time of diagnosis
Thereafter, every 1 to 2 years, depending on the status of the retina
Women with pre-existing diabetes should be screened preconception, during the 1st trimester, as needed during the pregnancy and for 1 year following
Intensive therapy- type 1 diabetes
Diabetes Control and Complications Trial (DCCT)
• Primary prevention cohort: reduced risk of developing retinopathy by 76%.
• Secondary intervention cohort: reduced risk of progression retinopathy by 54%.
Epidemiology of Diabetes Interventions and Complications (EDIC)
• Intensive group continued to have protection
Intensive therapy- type 1 diabetes
UK Prospective Diabetes Study (UKPDS)
• Good glycogenic control: reduced progression of retinopathy by 20-30%.
• Tight blood pressure control: reduced progression of retinopathy by 34%.
Post(UKPDS)
• Despite loss of giycemic control, reduced risk of micro vascular complications continued after 10 years

Microalbuminuria
Objectives
Type 1 diabetes
♣ Indicates increased risk fo end Stage renal disease
Type 2 diabetes
♣ Indicates increased risk fo a vascular event.
All the guidelines emphasize the need for intensive, aggressive management of cardiovascular risk factors
Interventions: glycogenic control (1 of2)
♣ DCCT provided good evidence that tight glucose control prevents/delays onset of micro albuminuria
♣ DCCT did not provide evidence that good control delays progression once microalbuminuria is present
Diabetic Nephropathy
Treatment
♣ Adults with persistent albuminuria (2.0mg/mmol in men, 2.8mg/ml in women) should be started on an ACE or ARB regardless of blood pressure
♣ Intensive treatment of blood pressure to achieve target <130/80 mmHg>
♣ Reduce salt in diet
♣ Reduce alcohol consumption
Estimated glomerular filtration rate (eGFR)(1 of 2)
♣ May underestimate actual renal function especially in women, the young and the obese ♣ Not accurate when eGFR > 60ml/min, but sufficiently accurate for clinical purposes when <60
♣ Risk of CVD increases as eGFR falls
♣ Risk of CVD increases as albuminuria increases
Estimated glomerular filtration rate (eGFR)(2 of 2)
<60 ml/min
♣ – osteodystrophy
♣ – anaemia
<30 ml/min
♣ – Pre-dialysis
<15 ml/min
♣ – Dialysis and transplant
Treatment of end Stage Renal Disease ESRD
- Prepare for eventual dialysis
- Peritoneal dialysis
- Haemodialysis
- Renal transplantation
