General approach to therapyNonpharmacologic
therapy Pharmacologic therapy
Treatment of concomitant diseases Treatment of acute complications Treatment of
chronic complications Outcome evaluation
Glycemic targets
●HbA1c < 7.0% (mean PG 150-160 mg/dl
●Pre-prandial PG <130 mg/dl●Post-prandial PG <180 mg/dl
●Individualization is key:●Tighter targets (6.0 - 6.5%) -
younger, healthier●Looser targets (7.5 - 8.0%+) - older,
comorbidities, hypoglycemia prone, etc.
●Avoidance of hypoglycemia
125

Nonpharmacologic Therapy●Medical nutrition therapy
●recommended for all DM patients●provides optimal metabolic and physiologic outcomes
(glucose, lipids, BP, proteinuria, weight)
●prevents/treats chronic DM complications●Regulates insulin administration with a
balanced diet to achieve/maintain a healthy weight
●carbohydrate counting or exchanges
●Promotes weight loss to overweight patients●caloric restriction
●Moderate weight loss has been shown to reduce CV risk as well as delay or prevent the onset of DM in those with pre-diabetes (follow TLC)
●General rule for weight loss diet is that it should supply 1000-1200 kcal/day for women and 1200-1600 kcal/day for men.
72
Nonpharmacologic Therapy●Exercise
●improves insulin resistance, glycemic control
●reduces CV risk (HTN and elevated serum lipids)
●helps with weight loss or maintenance
●improves well-being
●Patients without contraindications
● >150 min/week moderate-intensity aerobic exercise (50- 70% of maximum heart rate)
●resistance training for 30 min 3 times/week
●Start exercise slowly in previously sedentary patients.
Nonpharmacologic Therapy●Psychological assessment and care
●Determining the patient’s attitude regarding DM, expectations of medical management and outcomes, mood and affect, general and diabetes quality of life and financial, social and emotional resources.
●Immunization•Provide influenza vaccine annually to all diabetic patients
≥6 months of age•Administer pneumococcal polysaccharide vaccine to
all diabetic patients ≥2 years–One-time revaccination recommended for those >64 years previously
immunized at <65 yearsif administered >5 years ago
–Other indications for repeat vaccination: nephrotic syndrome, chronic renal disease, immunocompromised states
•Administer hepatitis B vaccination to unvaccinated adults with diabetes who are aged 19 through 59 years
•Consider administering hepatitis B vaccination to unvaccinated adults with diabetes who are aged ≥60 years

Therapeutic options:●Oral agents & non-insulin injectables
●Metformin●Sulfonylureas
●Thiazolidinediones●DPP-4 inhibitors
●GLP-1 receptor agonists●a-glucosidase inhibitors
●Amylin mimetics

154
Incretin-Based Therapies●The most recent advances in therapy for type 2 diabetes
have revolved around the discovery and exploration of the effects of incretins.
●Incretins are insulinotropic hormones secreted from specialized neuroendocrine cells in the small intestinal mucosa in response to carbohydrate ingestion and absorption.
●The two hormones accounting for most incretin effects are:
●glucose-dependent insulinotropic polypeptide (GIP)
●glucagonlike peptide-1 (GLP-1)●GIP and GLP-1 stimulate pancreatic β-cells in a glucose-
dependent manner, contributing to the early phase insulin response.
●GLP-1 also inhibits pancreatic α-cells, thus reducing glucagon secretion and hepatic glucose production.
●Incretin action is efficient, but short lived. As they enter the blood vessels, incretins undergo rapid metabolism via proteolytic cleavage by dipeptidyl peptidase-4 (DPP-4) to inactive metabolites. Thus, only small amounts are needed to exert their effects on glucose metabolism.
156
GLP-1 Mimetics/Analogs: Exenatide●Synthetic analog of amino acid peptide
exendin-4●isolated from Gila monster saliva
●Mechanism similar to human GLP-1●enhances insulin secretion
●suppresses postprandial glucagon when blood glucose elevated; reduces hepatic glucose production
●Slows gastric emptying, reduces food intake, promotes weight loss
●Unlike GLP-1, exenatide does not increase gastric secretions
157
Exenatide●Indication: adjunctive therapy for
type 2 DM●Not recommended in end-stage renal
disease or dialysis patients●prolongs t½
●increases incidence of GI side effects
●Adverse effects:●nausea, vomiting, diarrhea
●may improve over time●dose-related, slowly titrate dose
158
Exenatide●Postmarketing cases of acute pancreatitis
●May delay absorption of other medications: slow gastric emptying
●not recommended for patients with gastroparesis
●Dose●start with 5 mcg BID
●may titrate to 10 mcg BID when tolerated●inject subcutaneously within 60 min of
morning & evening meals
159
Exenatide●Average HbA1c reduction ~0.9%
●Significantly decreases postprandial glucose excursions
●Modest effects on FBG●Average weight loss in studies: 1 to 2
kg over 30 weeks●long-term, open-labeled trials show
continued weight loss for at least 2.5 years with 10 mcg BID dose
●Improvements in triglycerides & HDL seen with exenatide 10 mcg BID
16
DPP-IV Inhibitors●Inhibit DPP-IV which degrades GLP-1
●prolongs GLP-1 t½●GLP-1 deficient in type 2 DM
●Partially reduces elevated postprandial glucagon●Stimulates glucose-dependent insulin secretion

164
Amylin Receptor Agonists (Amylinomimetics)
●Amylin, or islet amyloid polypeptide, is a hormone found in the β-cells where it is co-manufactured, stored, and released with insulin in response to food intake.
●Its actions seem to be centrally mediated and include slowing gastric emptying, suppressing glucagon secretion, and modulating the regulation of appetite.
●Amylin is absent in patients with type 1 diabetes. In patients with type 2 diabetes, its concentrations are altered to mirror those of insulin at different points in the progression of the disease.
165
Amylinomimetics: Pramlintide●Adjunctive therapy for patients using
insulin●Synthetic analog of amylin
●neurohormone co-secreted from β-cells with insulin
●Suppresses postprandial glucagon secretion
●Reduces food intake●Slows gastric emptying
166
Pramlintide●Subcutaneous injection in abdomen
or thigh●variable absorption with arm injection
●Adverse effects:●GI most common
●nausea, vomiting, anorexia●may decrease over time
●dose-related, slowly titrate dose upwards
●May delay absorption of other medications; slow gastric emptying
167
Pramlintide●Reduce preprandial insulin dose 30 to
50% at pramlintide initiation●Basal insulin dose may be reduced if
FBG close to goal●Dosing
●type 2: 60 to 120 mcg prior to meals●type 1: 15 to 60 mcg prior to meals
●2.5 units on 100 units/ml insulin syringe = 15 mcg of pramlinitide
168
Pramlintide●Average HbA1c reduction 0.4 to 0.6%
●Decreases prandial glucose excursions●Little effect of FBG concentrations
●Main advantage in type 1 DM is that it stabilizes wide postprandial glycemic swings
●Average weight loss in controlled trials: 1 to 2 kg
186
Management strategies for Type 2 DM●Implementation strategies:
●Initial therapy●Advancing to dual combination therapy
●Advancing to triple combination therapy●Transitions to & titrations of insulin

hypoglycemiahyperosmolar
hyperglycemic state
206
1- Hypoglycemia●low blood sugar,
●defined clinically as a blood glucose level of less than 50 mg/dL.●Individuals with DM can experience symptoms of hypoglycemia at
varying blood glucose levels.●Patients who have regular blood glucose levels as high as 300 to 400
mg/dL may experience symptoms of hypoglycemia once blood glucose levels are lowered to the middle to upper 100 mg/dL range.
●Most people whose blood glucose levels are controlled adequately may experience symptoms when levels fall below 70 mg/dL.
●Symptoms include: shakiness, sweating, fatigue, hunger, headaches, and confusion.
●Common causes include:●delayed or inadequate amounts of food intake, especially
carbohydrates,●excessive doses of medications (e.g., sulfonylureas and
insulin),●exercising when insulin doses are reaching peak effect,
●inadequately adjusted drug therapy in renally or hepatically impaired patients.
207
Hypoglycemia – management●The key to successful management of hypoglycemia is
recognition and prevention.●Patients experiencing symptoms of hypoglycemia
should:●check their blood glucose level,
●consume 15 g of carbohydrate, and wait 10 to 15 minutes for symptom resolution (15 – 15 – 15)
●Examples of acceptable treatments may include a small box of raisins, approximately 120 mL of orange juice, approximately 240 mL of skim milk, or three to six glucose tablets.
●In patients receiving an α-glucosidase inhibitor in combination with a sulfonylurea or insulin, hypoglycemia should be treated with glucose tablets or skim milk owing to the mechanism of action of the α- glucosidase inhibitors.
●If the blood glucose level has dropped below 50 mg/dL, as much as 30 g of carbohydrate may be necessary to raise blood glucose levels adequately.
glucagon injection will vomit.208
●For patients with hypoglycemia experiencing a loss of consciousness,
●a glucagon emergency kit should be administered by intramuscular or subcutaneous route,
●Glucagon dose:●for a child younger than 5 years of age is 0.25 to
0.5 mg;
●for children 5 to 10 years of age, 0.5 to 1 mg;
●for patients older than 10 years, 1 mg)
●If glucagon is unavailable € IV glucose
●emergency medical personnel should be contacted.

PREVENTION AND MANAGEMENT OF
DIABETES COMPLICATIONS
•CVD is the major cause of morbidity, mortality for those with diabetes
•Common conditions coexisting with type 2 diabetes )e.g., hypertension, dyslipidemia) are clear risk
factors for CVD•Diabetes itself confers independent risk•Benefits observed when individual cardiovascular risk
factors are controlled to prevent/slow CVD in people with diabetes

substitute the other
•Multiple drug therapy )two or more agents at maximal doses) generally required to achieve BP targets )B)
•Administer one or more antihypertensive medications at bedtime )A)•If ACE inhibitors, ARBs, or diuretics are used, kidney function, serum potassium levels should be
monitored )E)•In pregnant patients with diabetes and chronic hypertension, blood pressure target goals of 110–
129/65–79 mmHg are suggested in interest of long-term maternal health and minimizing impaired fetal growth; ACE inhibitors, ARBs, contraindicated during pregnancy )E)
Recommendations: Dyslipidemia/Lipid Management
ADA. VI. Prevention, Management of Complications. Diabetes Care 2013;36)suppl 1):S31.
Screening•In most adult patients, measure fasting lipid profile at least annually )B)•In adults with low-risk lipid values
)LDL cholesterol >100 mg/dL, HDL cholesterol >50 mg/dL, and triglycerides >150 mg/dL ,)lipid assessments may be repeated every 2 years )E)
Treatment recommendations and goals )1)•To improve lipid profile in patients with diabetes, recommend lifestyle modification
)A), focusing on–Reduction of saturated fat, trans fat, cholesterol intake–Increased n-3 fatty acids, viscous fiber,

•In individuals with overt CVD–Lower LDL cholesterol goal of >70 mg/dL
)1.8 mmol/L), using a high dose of a statin, is an option )B)
•If targets not reached on maximal tolerated statin therapy
–Alternative therapeutic goal: reduce LDL cholesterol ~30–40% from baseline )B)
•Triglyceride levels >150 mg/dL )1.7 mmol/L), HDL cholesterol >40 mg/dL )1.0 mmol/L) in men and >50 mg/dL )1.3 mmol/L) in women, are desirable )C)
–However, LDL cholesterol–targeted statin therapy remains the preferred strategy )A)
•Combination therapy has been shown not to provide additional cardiovascularbenefit above statin therapy alone and is not generally recommended )A)
•Statin therapy is contraindicated in pregnancy )B)
Recommendations: Smoking Cessation
ADA. VI. Prevention, Management of Complications. Diabetes Care 2013;36)suppl 1):S34.
