PreTest • Name the three ways diabetes can be diagnosed? • What is the LDL goal for diabetics? • What is the optional LDL goal? • What is the A1C goal? • What is the BP goal? • What is the BP goal in patients with nephropathy?
Pre-Diabetes Definition If FBG >100 there is a 10-15% risk of DM within 7 years… or Fasting GTT
Metabolic Syndrome Elevated insulin level, fasting glucose or postprandial glucose and any 2 of the following: Triglyceride ≥ 150 or HDL ≤ 35 Blood pressure ≥ 140/90 or on medication for HTN Waist to hip ration > 0.9, a BMI ≥ 30 or waist circumference > 37 inches WHO Guidelines Any three of the following: Waist circumference >40 inches – men >35 inches – women Triglycerides ≥150 HDL ≤ 40 (men) or ≤ 50 (women) Fasting glucose ≥ 100 -- Hypertension ATP III Guidelines
Treatment of Metabolic Syndrome TLC: Therapeutic Lifestyle Changes Smoking cessation Increasing physical activity Weight reduction Healthy meal planning Pharmacotherapy Management of blood pressure Management of lipids Management of blood glucose Aspirin for CVD prevention
Pharmacotherapy – Metabolic Syndrome Always use TLC first and continue along with pharmacotherapy! Treat Lipids If patient has ↑ TG and ↓ HDL, treat TG If patient has ↑ LDL & TG and ↓ HDL, treat LDL first then treat TG Treat LDL with statins Treat TG & HDL with fibrates and niacin
Pharmacotherapy – Metabolic Syndrome Treat hypertension to goal (< 130/80) Low dose diuretic initially 66% will require 2 meds to control ACE inhibitor, ARBs, Calcium channel blockers Only 54% are treated for HTN Of those treated, only 28% are at goal
Pharmacotherapy – Metabolic Syndrome Treat clotting disorder Daily low dose aspirin (81-325 mg) for men over age 45 and postmenopausal women Treat blood glucose Insulin sensitizers Metformin and TZDs [pioglitazone (Actos) and rosiglitazone (Avandia)]
According to the American Diabetes Association 20.8 million children and adults in the U.S. have diabetes 14.6 million have been diagnosed with diabetes 6.2 million are unaware that they have the disease Diabetes represents 11% of the U.S. healthcare expenditure 1 out of every 10 health care dollars spent in the U.S. is spent on diabetes and its complications
Diabetes Classifications Pre-Diabetes Blood glucose levels are higher than normal but not high enough to be diagnosed with diabetes Risk factor for future diabetes and cardiovascular disease Type 1 Diabetes Type 2 Diabetes Gestational Diabetes Pregnant women who have never had diabetes but who have high blood glucose levels during pregnancy
Screening Individuals ≥45 years of age, particularly if BMI ≥25 kg/m2 Individuals <45 years of age and overweight with other risk factors for diabetes Are habitually physically inactive Have a first-degree relative with diabetes Are members of a high-risk ethnic population (African American, Latino, Native American, Asian American , Pacific Islander) Have delivered a baby weighing >9 lbs or have been diagnosed with gestational DM Are hypertensive (≥140/90 mmHg) Have an HDL cholesterol level <35 mg/dl and/or a triglyceride level >250mg/dl Have polycystic ovary syndrome On previous testing had impaired glucose tolerance or impaired fasting glucose Have other clinical conditions associated with insulin resistance Have a history of vascular disease
Diagnosis Three ways to diagnosis Fasting plasma glucose (FPG) Oral glucose tolerance test (OGTT) Symptoms of diabetes and a casual plasma glucose ≥200 mg/dl Each diagnostic criteria must be confirmed on a subsequent day unless unequivocal symptoms of hyperglycemia are present.
Complications Heart Disease and Stroke Heart disease death rates are 2 to 4 times higher than adults without DM The risk for stroke is 2 to 4 times higher than adults without DM High Blood Pressure 73% of adults with DM have a blood pressure greater than or equal to 130/80 mmHg or use prescription medications for hypertension Blindness Diabetic retinopathy is the leading cause of new cases of blindness in adults Kidney Disease Diabetes is the leading cause of kidney failure Nervous System Disease 60% to 70% of patients have mild to severe forms of nervous system damage. 30% of patients age 40 years or older have impaired sensation in the feet.
Complications Amputations More than 60% of non-traumatic lower-limb amputations are due to DM. The rate of amputation is 10 times higher in patients with DM. Dental Disease Periodontal (gum) disease is more common in DM patients. Complications of Pregnancy Poorly controlled DM before conception and during 1st trimester can cause major birth defects in 5% to 10% of pregnancies and 15% to 20% of spontaneous abortions. Poorly controlled DM during the 2nd and 3rd trimester can result in large babies. Sexual Dysfunction Men with DM are 2 times are likely to experience erectile dysfunction. Life-threatening Events Diabetic ketoacidosis (DKA) Infection DM patients are more susceptible to infection and have worse prognoses.
Complications and Preventative Care • Self-Management Training (education) • Blood Pressure Control • Lipid Management • Anti-Platelet Agents • Retinopathy • Nephropathy • Foot care • Smoking Cessation • Immunizations
Annual foot exam Condition of the skin, hair and toenails Musculoskeletal Deformities Pedal Pulses Sensory Exam Footwear assessment
Sensory Exam Test five sites per foot. The total duration of the approach, skin contact, and departure of the filament at each site should be approximately 1 to 2 seconds.
Footwear Assessment • Examine the inside of the shoes • Look at the type of footwear • Look at the fit of the footwear • Is the footwear appropriate? • Would the patient benefit from corrective footwear? • From inserts?
Diabetic Retinopathy 20 million diabetics in US 50% undiagnosed Only 50% of known diabetics receive appropriate eye care Therefore, DR is leading cause of blindness in working-age population in US Prevalence of DR increases with duration of diabetes (100% Type 1, 60% Type 2 after 20 years)
Pathophysiologyof DR Increased blood sugar shunts excess into aldose reductase pathway leading to sorbitol > loss of capillary intramural pericyte function causing weakness and outpouching of capillary walls Microaneurysms> increased leakage> rupture> hypoxia> infarction of nerve fiber layer (cotton-wool spots)> Compensation for hypoxia leads to vasoproliferation, neovascular changes> extension into vitreous > vitreal hemmorrhage, fibrosis with traction
Classification of DR Mild non-proliferative (aka Background)- microaneurysms Moderate non-proliferative-small vessel occlusion Severe non-proliferative-increased vessel occlusion Proliferative-abnormal vessel development and extension

Type 2 Diabetes Risk Factors • Family history of diabetes is very important • The dramatic increase in Type 2 Diabetes can be attributed to obesity and lack of physical activity • 80% of persons with Type 2 Diabetes are overweight or obese
Obesity: A Risk Factor • The U.S. Preventive Services Task Force (USPSTF) recommends that clinicians screen all adult patients for obesity by BMI and offer intensive counseling and behavioral interventions to promote sustained weight loss for obese adults. • Waist circumference, measured by the clinician, helps to assess further risk of obesity. http://www.ahrq.gov/clinic/uspstf/uspsobes.htm

Lifestyle: Weight Management Modest weight loss has been shown to reduce insulin resistance Lifestyle modifications should be the primary approach to weight loss. Physical activity and behavior modification are important components of weight loss programs and are helpful in maintenance of weight loss. Fat intake should be <7% of total calories Monitoring carbohydrates remains a key strategy in achieving glycemic control. Sugars and nonnutritive sweeteners are safe if consumed within the acceptable daily intake levels.
