World Diabetes
Day begins
5
The International
Diabetes Federation
and the World
Health Organization
created World
Diabetes Day in
response to
diabetes epidemic
Every year on November 14,
World Diabetes Day brings diabetes
to the attention of the world.
November 14 is
the birthday of
Frederick Banting,
one of the
discoverers of
insulin.
(c) Banting House National Historic Site of Canada
The theme is set by
the International
Diabetes Federation
and the World Health
Organization.
In 2006,
the United Nations
passed resolution
61/225. It asks the world
to observe November 14
as World Diabetes Day
and to take action to
address the diabetes
threat.
The campaign evolved from one day in the
year to a multi-year campaign
The campaign has
grown in strength
from humble
beginnings. . .
. . .to become a truly
global event.
2009-2013
Diabetes Education and Prevention
The campaign slogan is:
Let's Take Control of Diabetes.
Now.
2009-2013
Understand diabetes and take control
2009-2013
Let’s Take Control of Diabetes. Now.

The global symbol for diabetes was developed
during the Unite for Diabetes campaign.
Why a circle?
A positive symbol across cultures, the circle
symbolizes life and health.
Why blue?
The colour blue reflects the sky that unites all
nations. The blue border of the circle reflects the
colour of the sky and the flag of the United
Nations. The blue circle signifies the unity of the
global diabetes community in response to the
diabetes epidemic.

Epidemiology
An ancient problemAn ancient problem
• Diabetes mellitus had been known since
ancient times. Egyptian writings from as
early as 1500BC described a wasting
disease in which the sufferer produced
sweet-tasting urine. Egyptian physician
Hesy Ra makes the first mention about it
from Egypt on the Ebers Papyrus.
• Greeks & RomansGreeks & Romans
• History of Diabetes reveals the contributions of
Greeks and Romans. The famous Greek
physician Aretaeus coined the Greek word
Diabetes which means siphon. It acts like a
siphon, melting down flesh and limbs in urine.
• He lived in the first Century AD. His work on
Diabetes is a relic of antiquity. Diabetes was
researched by the Egyptians as well.
From the Ancient Greek διαβαίνω (diabainō, “to pass through”), via the
participle διαβήτης (diabētēs, “passing through”). This refers to the excessive
amounts of urine produced by sufferers.
• Indian FindingsIndian Findings
• History of diabetes is 2500 years old. Diabetes
mentioned in the old Indian medical texts.
• Ayurvedic authorities Sushruta and Charaka had
described it as Madhu Meha. It meant Honey Urine.
• They found that its victims passed large amounts of
sugar laden urine which attracted ants.
• Hence they called it Madhu Meha before 2500 years, a
term which is even now commonly used.
• The medical identification of the disease:
• Paracelsus for the first time identified the gravity of the
disease.
• The word diabetes mellitus was first used by the English
physician Thomas Willis in the year 1675. In nineteenth
century chemical tests were conducted in laboratory to
diagnose the type of this disease.
• The French researcher Claude Bernard examined the
working of pancreas and rate of metabolism in the liver
area.
• The breakthrough occurred in 1869 by the German
medical student, Paul Langerhans, who discovered the
two systems of cells in pancreas. The one system is
responsible for normal production of juice, while the
function of the other system still remained a mystery.
• From the 1850's onwards, autopsies of
people who had died from diabetes
suggested that the problem was caused
when the pancreas did not function
properly.
• Many physicians speculated that
specialised cells, called the islets of
Langerhans, produced a chemical that
allowed the body to regulate its blood
sugar level. Diabetes was caused when
this chemical was not produced.
• 346 million people worldwide have diabetes.
• In 2004, an estimated 3.4 million people died
from consequences of high blood sugar.
• More than 80% of diabetes deaths occur in
low- and middle-income countries.
• WHO projects that diabetes deaths will
double between 2005 and 2030.
• Healthy diet, regular physical activity,
maintaining a normal body weight and
avoiding tobacco use can prevent or delay
the onset of type 2 diabetes.
• RESULTS— The prevalence of diabetes for all age-
groups worldwide was estimated to be 2.8% in 2000 and
4.4% in 2030. The total number of people with diabetes
is projected to rise from 171 million in 2000 to 366 million
in 2030.
• The prevalence of diabetes is higher in men than
women, but there are more women with diabetes than
men. The urban population in developing countries is
projected to double between 2000 and 2030.
• The most important demographic change to diabetes
prevalence across the world appears to be the increase
in the proportion of people 65 years of age.
• DIABETES CARE, VOLUME 27, NUMBER 5, MAY 2004
• The Worst Affected
• If the same trend continues in India, this
country will have 184 million diabetics in
2030 whereas WHO estimated it as 79
million. The true facts about diabetes are
staggering indeed!
• RESULTS—The prevalence of type 2 diabetes
was 4.3% and IFG was 12.4%.
• The subjects with higher family income had
significantly higher prevalence of type 2 diabetes
(5.9 vs. 3.5%), and IFG (15.6 vs. 10.8%), than
those with lower income.
• Wealthy class, family history of diabetes,
reduced physical exercise, and increased age,
BMI, and WHR were the important predictors of
diabetes.

Classification of diabetes
• The classification of diabetes includes four clinicalThe classification of diabetes includes four clinical
classes:classes:
• Type 1 diabetes (results from β-cell destruction, usually
leading to absolute insulin deficiency)
• Type 2 diabetes (results from a progressive insulin
secretory defect on the background of insulin resistance)
• Other specific types of diabetes due to other causes,
e.g., genetic defects in β-cell function, genetic defects in
insulin action, diseases of the exocrine pancreas (such
as cystic fibrosis), and drug- or chemical-induced (such
as in the treatment of HIV/AIDS or after organ
transplantation)
• Gestational diabetes mellitus (GDM) (diabetes
diagnosed during pregnancy that is not clearly overt
diabetes)

• Progression to diabetes among those with
prediabetes is not inevitable. Studies suggest
that weight loss and increased physical activity
among people with prediabetes prevent or delay
diabetes and may return blood glucose levels to
normal.
• People with prediabetes are already at
increased risk for other adverse health
outcomes such as heart disease and stroke.

DETECTION AND DIAGNOSIS OFDETECTION AND DIAGNOSIS OF
GESTATIONAL DIABETES MELLITUSGESTATIONAL DIABETES MELLITUS
Gestational Diabetes Mellitus
• DefinitionDefinition
• Gestational diabetes mellitus (GDM) is defined
as any degree of glucose intolerance with onset
or first recognition during pregnancy.
• Approximately 7% of all pregnancies are
complicated by GDM, resulting in more than
200,000 cases annually. The prevalence may
range from 1 to 14% of all pregnancies,
depending on the population studied and the
diagnostic tests employed.
• The American Diabetes Association released new
guidelines for diagnosing gestational diabetes.
• Women without diabetes will still be tested for
gestational diabetes between weeks 24 and 28.
• But the criteria for gestational diabetes have been
broadened, and more diagnoses of the condition are
expected. Blood glucose cutoff points have been
lowered, and only one test showing high levels is
needed, not two as in the past.
• The new guidelines aim to catch more cases of
gestational diabetes, which can lead to a large baby,
posing risks for both newborn and mother. Gestational
diabetes can also lead to type 2 diabetes.
• Source: Diabetes Care, January 2011
Recommendations:Recommendations:
Detection and Diagnosis of GDMDetection and Diagnosis of GDM
• Screen for undiagnosed type 2 diabetes at the
first prenatal visit in those with risk factors, using
standard diagnostic criteria (B)
• In pregnant women not previously known to
have diabetes, screen for GDM at 24-28 weeks
gestation, using a 75-g OGTT and the diagnostic
cut points.(B)
ADA. III. Detection and Diagnosis of GDM. Diabetes Care 2011;34(suppl 1):S15.
• Low-risk status requires no glucose testing, but
this category is limited to those women meeting
all of the following characteristics:
• Age <25 years
• Weight normal before pregnancy
• Member of an ethnic group with a low
prevalence of GDM
• No known diabetes in first-degree relatives
• No history of abnormal glucose tolerance
• No history of poor obstetric outcome
• One-step approach:
• Two-step approach:
Screening for and Diagnosis of GDMScreening for and Diagnosis of GDM
• Perform a 75-g OGTT, with plasma glucose
measurement fasting and at 1 and 2 h, at 24-28
weeks of gestation in women not previously
diagnosed with overt diabetes
• Perform OGTT in the morning after an overnight
fast of at least 8 h
• GDM diagnosis: when any of the following
plasma glucose values are exceeded
– Fasting ≥92 mg/dl (5.1 mmol/l)
– 1 h ≥180 mg/dl (10.0 mmol/l)
– 2 h ≥153 mg/dl (8.5 mmol/l)
ADA. III. Detection and Diagnosis of GDM. Diabetes Care 2011;34(suppl 1):S15. Table 6.
• With either approach, the diagnosis of
GDM is based on an OGTT. Diagnostic
criteria for the 100-g OGTT are derived
from the original work of O’Sullivan and
Mahan, modified by Carpenter and
Coustan.
• Alternatively, the diagnosis can be made
using a 75-g glucose load and the glucose
threshold values listed for fasting, 1 h, and
2 h ; however, this test is not as well
validated for detection of at-risk infants or
mothers as the 100-g OGTT.
Recommendations:Recommendations:
Detection and Diagnosis of GDMDetection and Diagnosis of GDM
• Screen women with GDM for persistent diabetes
6-12 weeks postpartum (E)
• Women with a history of GDM should have
lifelong screening for the development of
diabetes or prediabetes at least every three
years (E)
ADA. III. Detection and Diagnosis of GDM. Diabetes Care 2011;34(suppl 1):S15.
Management of
Diabetes Mellitus
Nutrition Recommendations
• Carbohydrate
– 60-70% calories from carbohydrates and
monounsaturated fats
• Protein
– 10-20% total calories
Nutrition Recommendations
• Fat
– <10% calories from saturated fat
– 10% calories from PUFA
– <300 mg cholesterol
• Fiber
– 20-35 grams/day
• Alcohol
– Type I – limit to 2 drinks/day, with meals
– Type II – substitute for fat calories
Physical activity
Recommendations
• People with diabetes should be advised to perform at
least 150 min/week of moderate-intensity aerobic
physical activity (50–70% of maximum heart rate). (A)
• In the absence of contraindications, people with type 2
diabetes should be encouraged to perform resistance
training three times per week. (A)
• Exercise is an important part of the diabetes
management plan. Regular exercise has been
shown to improve blood glucose control, reduce
cardiovascular risk factors, contribute to weight
loss, and improve well-being.
• Furthermore, regular exercise may prevent type
2 diabetes in high-risk individuals.
• Structured exercise interventions of at least 8
weeks' duration have been shown to lower A1C
by an average of 0.66% in people with type 2
diabetes, even with no significant change in BMI.
Dm presentation
Old and new drugs…
• Combination therapy
• Favorites: metformin, sulfonylureas,
thiazolidinediones
• New classes…
• -DPP4 inhibitors: Sitagliptin and Vildagliptin
(Galvus)
• -GLP-1 agonists: Exenatide and Liraglutide
• -Glitazars: Muraglitazar
Dm presentation
Which oral drug to start with?
• Although there are numerous options in oral medications
for type 2 diabetes, an older drug -- metformin -- may be
the best first-line option, according to a new analysis of
research on diabetes medications.
• The analysis included six classes of oral diabetes
medications, and found that all of them lower blood
sugar levels by a similar amount. The authors suggest
that metformin is probably the best first-line choice
because it has fewer side effects than other drugs and,
because it's an older medication and available in a
generic form, it also costs less.
• Metformin………Welcome back?
• Metformin is usually the first oral
medication chosen to treat elevated
blood sugars in Type 2 diabetics. Its
main action is to decrease glucose
production in the liver. It may cause
gastrointestinal upset, such as nausea
and diarrhea, but these effects can be
minimized by starting with a low dose
and increasing gradually. Often,
metformin leads to weight loss which is
usually a beneficial side effect.

Dm presentation
DPP4 inhibitors
• Sitagliptin and Vildagliptin
• Incretins are hormones released by the GI tract in response to
nutrient ingestion that stimulate beta cells to secrete insulin—these
effects are diminished in T2DM
• DPP4 is a protease that breaks down the endogenous incretin
glucagon-like peptide (GLP)-1
• This class prevents the degradation of GLP-1 by competitively and
reversibly inhibiting the protease DPP4, and leads to longer
presence and actions of GLP-1
• Side Effects: No weight gain! rare hypoglycemia.
• Both to be used as a combination, both oral. Sitagliptin approved in
2006, Vildagliptin awaiting approval.
GLP-1 agonists
• Exenatide and Liraglutide
• Exogenous GLP-1 products that are resistant to DPP4
degradation, same actions as the endogenous incretin.
• Also known as incretin mimetics.
• Exenatide a 2xd inj. approved 2005 for use with
metformin and/or a sulfonylurea.
• Side effects: hypoglycemia (esp with sulfonylureas),
weight loss.
• Contra: GI dz, renal Cr <30mL/min. Current trials for
once weekly injection.
• Liraglutide is awaiting approval. Has longer half life than
exenatide thus only requiring once daily injections. Same
side effects, no contraindications identified yet.
Glitazars
• Muraglitazar
• Approved by FDA, then withdrawn in Spring 2006. Other trials in this
category are in progress.
• Glitazars activate two subtypes of receptors called peroxisome
proliferator–activated receptors (PPARs).
• PPARgamma activation reduces insulin resistance and improves
glycemic control, while activation of PPARalpha reduces
triglycerides and increases HDL concentration by increasing fatty
acid oxidation.
• Oral dose. Side effects: w. gain, edema, low incidence of coronary
and cerebral vascular events, possible congestive heart failure-FDA
decided it was of enough significance.
• Goodbye Glitazars?Goodbye Glitazars?
Why Insulin in Type 2 Diabetes?
Dm presentation
• Studies show that insulin may slow the
progression of diabetes mellitus Type 2
and delay its devastating consequences,
because taking insulin eliminates the
stress that the beta cells of the pancreas
go through to make and release the
hormone.
Dm presentation
Insulin Analogs
• Analogs are more predictable and more reliable and
consistent in action. Less chance of hypoglycemia.
• Rapid Acting:
-Humalog (Lispro)
-Novolog (Aspart)
-Apidra (Glulisine)
• Long Acting (Basal):
- Lantus (Glargine)
- Levemir (Detemir)

• Abstract
• Aims  To compare maternal and neonatal outcomes in women with gestational diabetes treated with diet,
metformin and/or insulin in routine clinical practice in a single centre.
• Methods  We analysed prospectively collected data from the National Women’s Health database for all
women with gestational diabetes who delivered between January 2007 and December 2009. Since June
2007, women requiring medication have been given a choice of either metformin or insulin treatment, except
women with a fetal abdominal circumference less than the 10th percentile, who were not offered metformin.
• Results  There were 1269 women with gestational diabetes; treatment was diet in 371, insulin in 399 and
metformin in 465 (249 metformin alone, 216 metformin and insulin). Women treated with metformin and/or
insulin had significantly higher BMIs compared with those in the diet group (P < 0.001) and had a higher
fasting glucose at diagnosis (p < 0.001). Women treated with insulin had higher rates of Caesarean delivery
(45.6% insulin, 37% metformin, 34% diet, P = 0.02) than women treated with metformin or diet. They also
had higher rates of preterm births (19.2% insulin, 12.5% metformin, 12.1% diet, P = 0.005), customized
large-for-gestational-age infants (18.5% insulin, 12.5% metformin, 12.4% diet, P = 0.02), neonatal
admissions (18.7% insulin, 12.7% metformin, 14.0% diet, P = 0.04) and neonatal intravenous dextrose use
(11.1% insulin, 5.1% metformin, 7.4% diet, P = 0.004). Neonatal outcomes were similar between diet- and
metformin-treated women.
• Conclusions  In routine practice, use of metformin in gestational diabetes was
associated with fewer adverse outcomes compared with insulin.
Recommendations: Glucose MonitoringRecommendations: Glucose Monitoring
• Self-monitoring of blood glucose should be
carried out 3+ times daily for patients using
multiple insulin injections or insulin pump
therapy (A)
• For patients using less frequent insulin
injections, noninsulin therapy, or medical
nutrition therapy alone
– SMBG may be useful as a guide to success of
therapy (E)
– However, several recent trials have called into
question clinical utility, cost-effectiveness, of routine
SMBG in non–insulin-treated patients

Recommendations: A1CRecommendations: A1C
• Perform A1C test at least twice yearly in patients
meeting treatment goals (and have stable
glycemic control) (E)
• Perform A1C test quarterly in patients whose
therapy has changed or who are not meeting
glycemic goals (E)
• Use of point-of-care testing for A1C allows for
timely decisions on therapy changes, when
needed (E)

• FACTS
• Diabetic retinopathy is the leading cause of vision loss in
adults of working age (20 to 65 years) in industrialised
countries. It is estimated that more than 2.5 million
people worldwide are affected by it.
• 74 percent of people who have diabetes for 10 years or
more will develop some form of diabetic retinopathy.
• Approximately 14 per cent of people with diabetes have
diabetic macular oedema and prevalence increases to
29 per cent for people with diabetes who use insulin for
more than 20 years.
• Left untreated, 25 per cent of people with diabetic
macular oedema will develop moderate vision loss within
three years.
• Estimates of the rate of annual eye exams vary greatly
by country and study, but the rate of screening is
generally fairly low (from 40 to 65 percent).
Recommendations:Recommendations:
Retinopathy ScreeningRetinopathy Screening
• Initial dilated and comprehensive eye
examination by an ophthalmologist or

Newer Directions
• The role of Dopamine in type 2 Diabetes
• The use of constant glucose monitors
(CGMS).
Proposed mechanism of action of Bromocriptine
in relation to type 2 DM
• Diabetes patients may have low morning levels of hypothalamic dopamine,
which is thought to lead to hyperglycemia and dyslipidemia
• CYCLOSET (special form of bromocriptine) is thought to reset aberrant low
morning hypothalamic dopaminergic activity, which may reset
neuroendocrine metabolic control

Match the Insulin to the Site
• Fast acting insulin can be injected into any
approved site.
• If injecting regular insulin, the abdomen
should be used.
• NPH should be injected into the thigh or
buttock.
A Straight Shot is Best
• On an angle or straight-in – patients have
been told to inject both ways.
So which won?
• Straight-in, in almost all cases. No skin
fold (pinch), use 90 degree—but if you
use a skin fold, you should angle your
injection.

A summary of the
Clinical Practice Recommendations as stated by the
American Diabetes Association and WHO in 2011
• “Transitions in care for youth with diabetes” was added.
• A section titled “Monogenic forms of diabetes” was
added.
• The use of the 75-g oral glucose tolerance test and new
diagnostic criteria was revised in the section titled

hypertension/BP control text was revised to incorporate
new evidence reinforcing the importance of
individualization of BP goals.
• “Children and Adolescents”, the text was revised to
remove lower limits on A1C targets and to include
discussion on appropriate individualization and safety.

  • 20. An ancient problemAn ancient problem
  • 21. • Diabetes mellitus had been known since ancient times. Egyptian writings from as early as 1500BC described a wasting disease in which the sufferer produced sweet-tasting urine. Egyptian physician Hesy Ra makes the first mention about it from Egypt on the Ebers Papyrus.
  • 22. • Greeks & RomansGreeks & Romans • History of Diabetes reveals the contributions of Greeks and Romans. The famous Greek physician Aretaeus coined the Greek word Diabetes which means siphon. It acts like a siphon, melting down flesh and limbs in urine. • He lived in the first Century AD. His work on Diabetes is a relic of antiquity. Diabetes was researched by the Egyptians as well. From the Ancient Greek διαβαίνω (diabainō, “to pass through”), via the participle διαβήτης (diabētēs, “passing through”). This refers to the excessive amounts of urine produced by sufferers.
  • 23. • Indian FindingsIndian Findings • History of diabetes is 2500 years old. Diabetes mentioned in the old Indian medical texts. • Ayurvedic authorities Sushruta and Charaka had described it as Madhu Meha. It meant Honey Urine. • They found that its victims passed large amounts of sugar laden urine which attracted ants. • Hence they called it Madhu Meha before 2500 years, a term which is even now commonly used.
  • 24. • The medical identification of the disease: • Paracelsus for the first time identified the gravity of the disease. • The word diabetes mellitus was first used by the English physician Thomas Willis in the year 1675. In nineteenth century chemical tests were conducted in laboratory to diagnose the type of this disease. • The French researcher Claude Bernard examined the working of pancreas and rate of metabolism in the liver area. • The breakthrough occurred in 1869 by the German medical student, Paul Langerhans, who discovered the two systems of cells in pancreas. The one system is responsible for normal production of juice, while the function of the other system still remained a mystery.
  • 25. • From the 1850's onwards, autopsies of people who had died from diabetes suggested that the problem was caused when the pancreas did not function properly. • Many physicians speculated that specialised cells, called the islets of Langerhans, produced a chemical that allowed the body to regulate its blood sugar level. Diabetes was caused when this chemical was not produced.
  • 26. • 346 million people worldwide have diabetes. • In 2004, an estimated 3.4 million people died from consequences of high blood sugar. • More than 80% of diabetes deaths occur in low- and middle-income countries. • WHO projects that diabetes deaths will double between 2005 and 2030. • Healthy diet, regular physical activity, maintaining a normal body weight and avoiding tobacco use can prevent or delay the onset of type 2 diabetes.
  • 27. • RESULTS— The prevalence of diabetes for all age- groups worldwide was estimated to be 2.8% in 2000 and 4.4% in 2030. The total number of people with diabetes is projected to rise from 171 million in 2000 to 366 million in 2030. • The prevalence of diabetes is higher in men than women, but there are more women with diabetes than men. The urban population in developing countries is projected to double between 2000 and 2030. • The most important demographic change to diabetes prevalence across the world appears to be the increase in the proportion of people 65 years of age. • DIABETES CARE, VOLUME 27, NUMBER 5, MAY 2004
  • 28. • The Worst Affected • If the same trend continues in India, this country will have 184 million diabetics in 2030 whereas WHO estimated it as 79 million. The true facts about diabetes are staggering indeed!
  • 29. • RESULTS—The prevalence of type 2 diabetes was 4.3% and IFG was 12.4%. • The subjects with higher family income had significantly higher prevalence of type 2 diabetes (5.9 vs. 3.5%), and IFG (15.6 vs. 10.8%), than those with lower income. • Wealthy class, family history of diabetes, reduced physical exercise, and increased age, BMI, and WHR were the important predictors of diabetes. • Diabetes and Impaired Fasting Glycemia in a Rural Population of Bangladesh • M.

  • 56. Gestational Diabetes Mellitus • DefinitionDefinition • Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with onset or first recognition during pregnancy. • Approximately 7% of all pregnancies are complicated by GDM, resulting in more than 200,000 cases annually. The prevalence may range from 1 to 14% of all pregnancies, depending on the population studied and the diagnostic tests employed.
  • 57. • The American Diabetes Association released new guidelines for diagnosing gestational diabetes. • Women without diabetes will still be tested for gestational diabetes between weeks 24 and 28. • But the criteria for gestational diabetes have been broadened, and more diagnoses of the condition are expected. Blood glucose cutoff points have been lowered, and only one test showing high levels is needed, not two as in the past. • The new guidelines aim to catch more cases of gestational diabetes, which can lead to a large baby, posing risks for both newborn and mother. Gestational diabetes can also lead to type 2 diabetes. • Source: Diabetes Care, January 2011
  • 58. Recommendations:Recommendations: Detection and Diagnosis of GDMDetection and Diagnosis of GDM • Screen for undiagnosed type 2 diabetes at the first prenatal visit in those with risk factors, using standard diagnostic criteria (B) • In pregnant women not previously known to have diabetes, screen for GDM at 24-28 weeks gestation, using a 75-g OGTT and the diagnostic cut points.(B) ADA. III. Detection and Diagnosis of GDM. Diabetes Care 2011;34(suppl 1):S15.
  • 59. • Low-risk status requires no glucose testing, but this category is limited to those women meeting all of the following characteristics: • Age <25 years • Weight normal before pregnancy • Member of an ethnic group with a low prevalence of GDM • No known diabetes in first-degree relatives • No history of abnormal glucose tolerance • No history of poor obstetric outcome
  • 62. Screening for and Diagnosis of GDMScreening for and Diagnosis of GDM • Perform a 75-g OGTT, with plasma glucose measurement fasting and at 1 and 2 h, at 24-28 weeks of gestation in women not previously diagnosed with overt diabetes • Perform OGTT in the morning after an overnight fast of at least 8 h • GDM diagnosis: when any of the following plasma glucose values are exceeded – Fasting ≥92 mg/dl (5.1 mmol/l) – 1 h ≥180 mg/dl (10.0 mmol/l) – 2 h ≥153 mg/dl (8.5 mmol/l) ADA. III. Detection and Diagnosis of GDM. Diabetes Care 2011;34(suppl 1):S15. Table 6.
  • 63. • With either approach, the diagnosis of GDM is based on an OGTT. Diagnostic criteria for the 100-g OGTT are derived from the original work of O’Sullivan and Mahan, modified by Carpenter and Coustan. • Alternatively, the diagnosis can be made using a 75-g glucose load and the glucose threshold values listed for fasting, 1 h, and 2 h ; however, this test is not as well validated for detection of at-risk infants or mothers as the 100-g OGTT.
  • 64. Recommendations:Recommendations: Detection and Diagnosis of GDMDetection and Diagnosis of GDM • Screen women with GDM for persistent diabetes 6-12 weeks postpartum (E) • Women with a history of GDM should have lifelong screening for the development of diabetes or prediabetes at least every three years (E) ADA.

  • 67. Nutrition Recommendations • Fat – <10% calories from saturated fat – 10% calories from PUFA – <300 mg cholesterol • Fiber – 20-35 grams/day • Alcohol – Type I – limit to 2 drinks/day, with meals – Type II – substitute for fat calories
  • 68. Physical activity Recommendations • People with diabetes should be advised to perform at least 150 min/week of moderate-intensity aerobic physical activity (50–70% of maximum heart rate). (A) • In the absence of contraindications, people with type 2 diabetes should be encouraged to perform resistance training three times per week. (A)
  • 69. • Exercise is an important part of the diabetes management plan. Regular exercise has been shown to improve blood glucose control, reduce cardiovascular risk factors, contribute to weight loss, and improve well-being. • Furthermore, regular exercise may prevent type 2 diabetes in high-risk individuals. • Structured exercise interventions of at least 8 weeks' duration have been shown to lower A1C by an average of 0.66% in people with type 2 diabetes, even with no significant change in BMI.
  • 71. Old and new drugs… • Combination therapy • Favorites: metformin, sulfonylureas, thiazolidinediones • New classes… • -DPP4 inhibitors: Sitagliptin and Vildagliptin (Galvus) • -GLP-1 agonists: Exenatide and Liraglutide • -Glitazars: Muraglitazar
  • 73. Which oral drug to start with? • Although there are numerous options in oral medications for type 2 diabetes, an older drug -- metformin -- may be the best first-line option, according to a new analysis of research on diabetes medications. • The analysis included six classes of oral diabetes medications, and found that all of them lower blood sugar levels by a similar amount. The authors suggest that metformin is probably the best first-line choice because it has fewer side effects than other drugs and, because it's an older medication and available in a generic form, it also costs less.
  • 74. • Metformin………Welcome back? • Metformin is usually the first oral medication chosen to treat elevated blood sugars in Type 2 diabetics. Its main action is to decrease glucose production in the liver. It may cause gastrointestinal upset, such as nausea and diarrhea, but these effects can be minimized by starting with a low dose and increasing gradually. Often, metformin leads to weight loss which is usually a beneficial side effect. • References • American Association of Clinical Endocrinologists Medical Guidelines for Clinical Practice for the Manage 2011 • Medical Management of Hyperglycemia in Type 2 Diabetes: A Consensus Algorithm for the Initiation and • "American Family Physician"; Management of Blood Glucose in Type 2 Diabetes Mellitus; Cynthia Ripsin , M.D., Helen Kang, M.D. and Randall Urban, M.D.; January 2009 • Centers for Disease Control and Prevention: National Diabetes Fact Sheet 2007

  • 83. Why Insulin in Type 2 Diabetes?
  • 85. • Studies show that insulin may slow the progression of diabetes mellitus Type 2 and delay its devastating consequences, because taking insulin eliminates the stress that the beta cells of the pancreas go through to make and release the hormone.

Med. 28, 1082–1087 (2011) • Abstract • Aims  To compare maternal and neonatal outcomes in women with gestational diabetes treated with diet, metformin and/or insulin in routine clinical practice in a single centre. • Methods  We analysed prospectively collected data from the National Women’s Health database for all women with gestational diabetes who delivered between January 2007 and December 2009. Since June 2007, women requiring medication have been given a choice of either metformin or insulin treatment, except women with a fetal abdominal circumference less than the 10th percentile, who were not offered metformin. • Results  There were 1269 women with gestational diabetes; treatment was diet in 371, insulin in 399 and metformin in 465 (249 metformin alone, 216 metformin and insulin). Women treated with metformin and/or insulin had significantly higher BMIs compared with those in the diet group (P < 0.001) and had a higher fasting glucose at diagnosis (p < 0.001). Women treated with insulin had higher rates of Caesarean delivery (45.6% insulin, 37% metformin, 34% diet, P = 0.02) than women treated with metformin or diet. They also had higher rates of preterm births (19.2% insulin, 12.5% metformin, 12.1% diet, P = 0.005), customized large-for-gestational-age infants (18.5% insulin, 12.5% metformin, 12.4% diet, P = 0.02), neonatal admissions (18.7% insulin, 12.7% metformin, 14.0% diet, P = 0.04) and neonatal intravenous dextrose use (11.1% insulin, 5.1% metformin, 7.4% diet, P = 0.004). Neonatal outcomes were similar between diet- and metformin-treated women. • Conclusions  In routine practice, use of metformin in gestational diabetes was associated with fewer adverse outcomes compared with insulin.

  1. Why is it interesting to do research in diabeets
  2. “ Standards of Medical Care in Diabetes—2011” contains all of the current and key clinical recommendations of the American Diabetes Association (ADA) These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, general treatment goals, and tools to evaluate the quality of care While individual preferences, comorbidities, and other patient factors may require modification of goals, targets that are desirable for most patients with diabetes are provided These standards are not intended to preclude clinical judgment or more extensive evaluation and management of the patient by other specialists as needed The recommendations included are screening, diagnostic, and therapeutic actions that are known or believed to affect health outcomes of patients with diabetes favorably The slides are organized to correspond with sections within the “Standards of Medical Care in Diabetes—2011” While not every section in the document is represented, these slides do incorporate the most salient points from the Position Statement These standards of care are revised annually by the ADA’s multidisciplinary Professional Practice Committee, incorporating new evidence; subsequently, they are reviewed and approved by the Executive Committee of ADA’s Board of Directors Reference American Diabetes Association.

  3. The three primary criteria for testing for diabetes in asymptomatic adult individuals (Table 4) are summarized on two slides; this slide (Slide 1 of 2) includes: Testing should be considered in all adults who are overweight (BMI ≥25 kg/m 2 ) and have additional risk factors Testing should be considered in adults of any age with BMI ≥25 kg/m 2 and one or more of the known risk factors listed on this slide It is important to know that the at-risk BMI may be lower in some ethnic groups, such as Asians Reference American Diabetes Association. Standards of medical care in diabetes—2011. Diabetes Care 2011;34(suppl 1):S14. Table 4.
  4. The three primary criteria for testing for diabetes in asymptomatic adult individuals (Table 4) are summarized on two slides; this slide (Slide 2 of 2) includes: In the absence of criteria (risk factors on previous slide), testing diabetes should begin at age 45 years If results are normal, testing should be repeated at least at 3-year intervals, with consideration of more frequent testing depending on initial results and risk status Age is a major risk factor for diabetes; therefore, testing of individuals without other risk factors should begin no later than at age 45 years The rationale for the 3-year interval is that false negatives will be repeated before substantial time elapses, and there is little likelihood that an individual will develop significant complications of diabetes within 3 years of a negative test result Given the need for follow-up and discussion of abnormal results, testing should be conducted within the health care setting Community screening outside a health care setting is not recommended because people with positive tests may not seek, or have access to, appropriate follow-up testing and care Conversely, there may be failure to ensure appropriate repeat testing for individuals who test negative Community screening may also be poorly targeted; i.e., it may fail to reach the groups most at risk and inappropriately test those at low risk (the worried well) or even those already diagnosed Reference American Diabetes Association. Standards of medical care in diabetes—2011. Diabetes Care 2011;34(suppl 1):S14. Table 4.
  5. Table 2, current diagnostic criteria for the diagnosis of diabetes, is divided into five slides On this slide, all four criteria are included: A1C ≥6.5% Fasting plasma glucose (FPG) ≥126 mg/dl (7.0 mmol/l) Two-hour plasma glucose ≥200 mg/dl (11.1 mmol/l) during an OGTT A random plasma glucose ≥200 mg/dl (11.1 mmol/l), in patients with classic symptoms of hyperglycemia or hyperglycemic crisis The subsequent slides examine each of the four criteria in greater detail Reference American Diabetes Association. Standards of medical care in diabetes—2011. Diabetes Care 2011;34(suppl 1):S13. Table 2.
  6. A1C In 2009, an International Expert Committee that included representatives of the American Diabetes Association (ADA), the International Diabetes Federation (IDF), and the European Association for the Study of Diabetes (EASD) recommended the use of the A1c test to diagnose diabetes, with a threshold of ≥6.5% 1 , and ADA adopted this criterion in 2010 2 The diagnostic test should be performed using a method certified by the National Glycohemoglobin Standardization Program (NGSP) and standardized or traceable to the Diabetes Control and Complications Trial (DCCT) reference assay 3 Point-of-care A1C assays are not sufficiently accurate at this time to use for diagnostic purposes 3 References International Expert Committee: International Expert Committee report on the role of the A1C assay in the diagnosis of diabetes.

  7. Optional DISCUSSION POINTS: Both fasting and postprandial glucose contribute to overall glycemic control as measured by A1C. The typical 24-h blood glucose profiles differ in healthy patients without diabetes (purple area) and patients with uncontrolled type 2 diabetes (turquoise and yellow area). In healthy individuals, fasting plasma glucose generally ranges between 70 and 110 mg/dL and postprandial glucose levels rarely exceed 140 mg/dL. Patients with uncontrolled diabetes typically have high fasting glucose and also have exaggerated postprandial glucose excursions. Both contribute to overall glucose control as measured by the A1C.
  8. Table 9, as shown on this slide, contains the correlation between A1C levels and mean plasma glucose (PG) levels based on data from the international A1C-Derived Average Glucose (ADAG) trial using frequent SMBG and continuous glucose monitoring (CGM) in 507 adults (83% Caucasian) with type 1, type 2, and no diabetes 1 The ADA and the American Association of Clinical Chemistry have determined that the correlation ( r = 0.92) is strong enough to justify reporting both an A1C result and an estimated average glucose (eAG) when a clinician orders the A1C test 2 A calculator for converting A1C results into eAG, in either mg/dl or mmol/l, is available at http://professional.diabetes.org/eAG.

  9. Two-hour plasma glucose (2-h PG) The two-hour plasma glucose test should be performed as described by the World Health Organization, using a glucose load containing the equivalent of 75 g anhydrous glucose dissolved in water The established glucose criteria for the diagnosis of diabetes (FPG, previous slide, and 2-h PG) remain valid Reference American Diabetes Association. Standards of medical care in diabetes—2011. Diabetes Care 2011;34(suppl 1):S13. Table 2.
  10. Random Plasma Glucose As with most diagnostic tests, a test result diagnostic of diabetes should be repeated to rule out laboratory error, unless the diagnosis is clear on clinical grounds, such as a patient with a hyperglycemic crisis or classic symptoms of hyperglycemia and a random plasma glucose ≥200 mg/dl Reference American Diabetes Association. Standards of medical care in diabetes—2011. Diabetes Care 2011;34(suppl 1):S13. Table 2.
  11. In 1997 and 203, The Expert Committee on the Diagnosis and Classification of Diabetes Mellitus 1,2 recognized an intermediate group of individuals whose glucose levels, although not meeting criteria for diabetes, are nevertheless too high to be considered normal This group was defined as having impaired fasting glucose (IFG) or impaired glucose tolerance (IGT) IFG: fasting plasma glucose (FPG) of 100-125 mg/dl (5.6-5.9 mmol/l) IGT: two-hour plasma glucose (2-h PG) on the 75-g oral glucose tolerance test (OGTT) of 140-199 mg/dl (7.8-11.0 mmol/l) It should be noted that the World Health Organization (WHO) and a number of other diabetes organizations define the cutoff for IFG at 110 mg/dl (6.1 mmol) Individuals with IFG and/or IGT have been referred to as having prediabetes, indicating a relatively high risk for future development of diabetes IFG and IGT should not be viewed as clinical entities in their own right but rather risk factors for diabetes as well as cardiovascular disease (CVD) IFG and IGT are associated with obesity (especially abdominal or visceral obesity), dyslipidemia with high triglycerides and/or low HDL cholesterol, and hypertension Individuals with an A1C of 5.7-6.4% should be informed of their increased risk for diabetes as well as CVD and counseled about effective strategies to lower their risks (see Prevention/Delay of Type 2 Diabetes ) References Expert Committee on the Diagnosis and Classification of Diabetes Mellitus.

  12. ADA and AACE Guidelines: Treatment Goals for A1C, FPG, and PPG The table presents guidelines from the American Diabetes Association (ADA) and the American Association of Clinical Endocrinologists (AACE). 1 – 3 ADA and AACE recommend slightly different treatment goals for FPG, PPG, and A1C for patients with type 2 diabetes. 1,2 Both organizations emphasize the importance of good glycemic control. The ADA suggests that the goal of treatment in the management of diabetes should be an A1C value less than 7%. 1,2 The AACE has recommended an A1C goal of ≤ 6.5%. 1,3 The ADA target of FPG levels between 90 and 130 mg/dL is based on the estimate of the range of average glucose values that would be associated with low risk of hypoglycemia and A1C &lt;7%. The AACE target of &lt;110 mg/dL is an effort to achieve normal levels of glycemia. 1 The ADA recommends reducing average PPG values (peak posprandial glucose level &lt;180 mg/dL), 2 whereas the AACE recommends targeting 2-hour postchallenge PPG values of &lt;140 mg/dL. 1 Purpose To provide a reminder of current guidelines for type 2 diabetes.

  14. Recommendations for testing for diabetes in asymptomatic patients are summarized on this slide For many illnesses, there is major distinction between screening and diagnostic testing; however, for diabetes, the same tests are used for “screening” as for diagnosis A1C, fasting plasma glucose (FPG), or two-hour oral glucose tolerance test (2-h OGTT) are appropriate to test for diabetes The 2-h OGTT identifies people with either impaired fasting glucose (IFG) or impaired glucose tolerance (IGT); therefore, more people at increased risk for the development of diabetes and cardiovascular disease (CVD) Type 2 diabetes has a long asymptomatic phase and significant clinical risk markers Testing for diabetes will also detect individuals at increased future risk for diabetes; i.e., those who may have prediabetes Reference American Diabetes Association.

Recommendations for the detection and diagnosis of gestational diabetes mellitus (GDM) are summarized on two slides; this slide ( Slide 1 of 2 ) includes: As the ongoing epidemic of obesity and diabetes has led to more type 2 diabetes in women of childbearing age, the number of pregnant women with undiagnosed type 2 diabetes has increased[24] Because of this, it is reasonable to screen women with risk factors for type 2 diabetes for diabetes at their initial prenatal visit, using standard diagnostic criteria; women with diabetes found at this visit should receive a diagnosis of overt, not gestational, diabetes References American Diabetes Association.

  17. GDM carries risks for the mother and neonate 1 The Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) study, 2 a large-scale (25,000 pregnant women) multinational epidemiologic study, demonstrated that risk of adverse maternal, fetal, and neonatal outcomes continuously increased as a function of maternal glycemia at 24–28 weeks, even within ranges previously considered normal for pregnancy. For most complications, there was no threshold for risk. These results have led to careful reconsideration of the diagnostic criteria for GDM After deliberations in 2008–2009, the International Association of Diabetes and Pregnancy Study Groups (IADPSG), an international consensus group with representatives from multiple obstetrical and diabetes organizations, including ADA, developed revised recommendations for diagnosing GDM. The group recommended that all women not known to have diabetes undergo a 75-g OGTT at 24–28 weeks of gestation Additionally, the group developed diagnostic cut points for the fasting, 1-h, and 2-h plasma glucose measurements that conveyed an odds ratio for adverse outcomes of at least 1.75 compared with the mean glucose levels in the HAPO study Current screening and diagnostic strategies, based on the IADPSG statement, 3 are outlined in Table 6, which is summarized on this slide References American Diabetes Association.

  18. Recommendations for the detection and diagnosis of gestational diabetes mellitus (GDM) are summarized on two slides; this slide ( Slide 2 of 2 ) includes: Women with a history of GDM have a greatly increased subsequent risk for diabetes 2 ; therefore, they should be screened for diabetes 6-12 weeks postpartum, using nonpregnant oral glucose tolerance test (OGTT) criteria, and should be followed for the development of diabetes or prediabetes (see Section II, “Testing for Diabetes in Asymptomatic Patients” ) Information on the National Diabetes Education Program campaign to prevent type 2 diabetes in women with GDM can be found at: http://ndep.nih.gov/media/NeverTooEarly_Tipsheet.pdf References American Diabetes Association.

  21. Required DISCUSSION POINTS: --Upon food ingestion, GLP-1 is secreted into the circulation from L cells of small intestine. --GLP-1 increases beta-cell response by enhancing glucose-dependent insulin secretion. --GLP-1 decreases beta-cell workload and hence the demand for insulin secretion by: --Regulating the rate of gastric emptying such that meal nutrients are delivered to the small intestine and, in turn, absorbed into the circulation more smoothly, reducing peak nutrient absorption and insulin demand (beta-cell workload) --Decreasing postprandial glucagon secretion from pancreatic alpha cells, which helps to maintain the counterregulatory balance between insulin and glucagon --Reducing postprandial glucagon secretion, GLP-1 has an indirect benefit on beta-cell workload, since decreased glucagon secretion will produce decreased postprandial hepatic glucose output --Having effects on the central nervous system, resulting in increased satiety (sensation of satisfaction with food intake) and a reduction of food intake --By decreasing beta-cell workload and improving beta-cell response, GLP-1 is an important regulator of glucose homeostasis.

  22. DISCUSSION: Classic understanding of the pathogenesis of type 2 diabetes consists of progressive insulin resistance coupled with gradual deterioration of beta-cell function The literature makes it clear there is another fundamental defect in the pathogenesis of type 2 diabetes: dysregulation of incretin hormones such as GLP-1 The acute effects of incretin hormones play a major role in insulin secretion from the beta cell In fact, the incretin effect accounts for up to 70% of the insulin response to oral glucose intake 1 REFERENCE: Holst JJ, Gromada J. Role of incretin hormones in the regulation of insulin secretion in diabetic and nondiabetic humans. Am J Physiol Endocrinol Metab . 2004;287(2):E199-E206. *Note to speakers: This is a graphic that is used in other speaker slide decks. Please note that the title and graphics have been changed slightly to reflect the core message of this deck.
  23. Not Required DISCUSSION POINTS: --The half-life of GLP-1 is less than 2 minutes – meaning a continuous infusion of exogenous GLP-1 would be necessary to overcome the enzymatic degradation of GLP-1 by DPP-IV. --Inhibition of DPP-IV, which would extend the half-life of endogenous GLP-1, is one avenue of research. --Incretin mimetics are compounds that mimic GLP-1’s glucoregulatory effects, but are resistant to DPP-IV degradation. Examples are: --Analogs of the natural GLP-1 molecule. --Exenatide, a naturally occurring incretin mimetic that mimics multiple glucoregulatory effects of GLP-1 and is resistant to DPP-IV enzymatic degradation, is the first FDA-approved incretin mimetic. Exenatide is the active ingredient in BYETTA.
  24. Beta-Cell Function Declines as Diabetes Progresses The reason that diabetes develops and progresses is because there is a loss of beta-cell function. The data points for the time of diagnosis (0) and the subsequent 6 years were taken from a subset of the UKPDS population and were determined by the homeostatic assessment model (HOMA). The beginning of b eta -cell loss was estimated by extrapolation back to 100% function and the lack of significant insulin secretion by extrapolation forward. In the earliest phase, when b eta -cell function is not impaired, the ability of the b eta cells to hypersecrete insulin masks the impaired glucose tolerance, often for years. As b eta cell function declines further, mild postprandial hyperglycemia develops, reflecting the inability of the b eta cell to hypersecrete enough insulin to overcome insulin resistance. Based on this hypothetical model, at the time of diagnosis, b eta -cell function has typically declined by 50%. Reference Lebovitz HE. Insulin secretagogues: old and new. Diabetes Reviews. 1999;7:139-153.
  25. Possible Barriers to the Initiation of Insulin There are patient-related and health care professional – related barriers to initiating insulin, some of which overlap. Patient-related barriers include: Fear of needles Negative misconceptions about insulin Inconvenience Patient perception as personal failure Health care professional – related barriers include: Lack of available educational tools/resources Lack of familiarity/comfort with insulin Time constraints Overlapping barriers include: Fear of hypoglycemia Weight gain Complexity of dosing regimen Cost References Korytkowski M. When oral agents fail: practical barriers to starting insulin. Int J Obes . 2002;26(suppl 3):S18-S24. Larme AC, Pugh JA. Evidence-based guidelines meet the real world: the case of diabetes care.

  26. Peak time refers to time to peak insulin levels (PK) vs. time to peak glucose-lowering action (PD) Replacement of the proline amino acid residue by aspartic acid disrupts the monomer-monomer interface between proline B28 and glycine B23. Repulsion between the negatively charged aspartic acid and the nearby glutamic acid B21 also contributes to the rapid dissociation of insulin aspart into monomers. NovoLog ® therefore has less tendency to form hexamers in solution and is absorbed more rapidly after subcutaneous injection than is regular human insulin.
  27. Recommended glycemic goals for nonpregnant adults (Table 10) are shown on three slides Slide 1 of 3 These recommendations are based on those for A1C values, with listed blood glucose levels that appear to correlate with achievement of an A1C of &lt;7% The issue of preprandial versus postprandial self-monitoring of blood glucose (SMBG) is complex; in some epidemiological studies, elevated postchallenge two-hour oral glucose tolerance test (2-h OGTT) glucose values have been associated with increased cardiovascular risk independent of fasting plasma glucose (FPG) In diabetic subjects, some surrogate measures of vascular pathology, such as endothelial dysfunction, are negatively affected by postprandial hyperglycemia Postprandial hyperglycemia, like preprandial hyperglycemia, contributes to elevated A1C levels, with its relative contribution being higher at A1C levels that are closer to 7% However, outcome studies have clearly shown A1C to be the primary predictor of complications, and landmark trials such as the Diabetes Control and Complications Trial (DCCT) and the UK Prospective Diabetes Study (UKPDS) relied overwhelmingly on preprandial SMBG For individuals who have premeal glucose values within target but A1C values above target, a reasonable recommendation for postprandial testing and targets is monitoring postprandial plasma glucose 1-2 hours after the start of the meal and treatment aimed at reducing PPG values to &lt;180 mg/dl to help lower A1C Reference American Diabetes Association. Standards of medical care in diabetes—2011. Diabetes Care 2011;34(suppl 1):S20-21. Table 10.
  28. Recommended glycemic goals for nonpregnant adults (Table 10) are shown on three slides Slide 2 of 3 Glycemic goals should be individualized, based on a patient’s duration of diabetes, age, life expectancy, comorbid conditions, known cardiovascular disease (CVD) or advanced microvascular complications, unawareness of hypoglycemia, and other considerations Reference American Diabetes Association.

  29. Recommended glycemic goals for nonpregnant adults (Table 10) are shown on three slides Slide 3 of 3 For individual patients, more or less stringent glycemic goals may be appropriate If A1C goals are not met despite reaching preprandial glucose goals, postprandial glucose may be targeted Reference American Diabetes Association. Standards of medical care in diabetes—2011. Diabetes Care 2011;34(suppl 1):S21. Table 10.
  30. For patients using multiple insulin injections or insulin pump therapy, self-monitoring of blood glucose (SMBG) should be conducted three or more times daily (A) 1 SMBG may be used as a guide to the success of therapy if patients are using less frequent insulin injections, noninsulin therapy, or medical nutrition therapy (MNT) alone (E) 1 In non–insulin-treated patients, however, several recent clinical trials have called into question the clinical utility and cost-effectiveness of routine SMBG 2-4 References American Diabetes Association.

  31. A1C testing should be performed routinely in all patients with diabetes, at initial assessment and then as part of continuing care For any individual patient, the frequency of A1C testing depends on the clinical situation, treatment regimen used, and clinician judgment Recommendations for A1C testing are summarized on this slide An A1C test should be performed at least twice a year in patients who are meeting their treatment goals and have stable glycemic control (E) In patients whose therapy has changed or who are not meeting glycemic goals, the A1C test should be performed quarterly (E); this helps determine whether a patient’s glycemic targets are being reached and maintained When needed for timely decisions on when to change therapy, point-of-care testing for A1C may be used (E); availability of A1C results when a patient is seen has been reported to result in increased intensification of therapy and improvement in glycemic control The A1C test is subject to certain limitations: conditions that affect erythrocyte turnover (e.g., hemolysis, blood loss) and hemoglobin variants must be considered, particularly when the A1C result does not correlate with the patient’s clinical situation; in addition, A1C does not provide a measure of glycemic variability or hypoglycemia For patients prone to glycemic variability (especially type 1 diabetic patients, or type 2 diabetic patients with severe insulin deficiency), glycemic control is best judged by the combination of result of self-monitoring of blood glucose (SMBG) testing and A1C The A1C may also serve as a check on the accuracy of a patient’s meter and adequacy of the SMBG testing schedule Reference American Diabetes Association.

  33. The general recommendations for medical nutrition therapy (MNT) are included on this slide Individuals who have pre-diabetes or diabetes should receive individualized MNT as needed to achieve treatment goals, preferably provided by a registered dietitian familiar with the components of diabetes MNT (A) When delivered by a registered dietitian according to nutrition practice guidelines, MNT is reimbursed as part of the Medicare program as overseen by the Centers for Medicare and Medicaid Services (http://www.cms.gov/medicalnutritiontherapy/) Because it can result in cost savings and improved outcomes (B), MNT should be covered by insurance and other payors (E) Although numerous studies have attempted to identify the optimal mix of macronutrients for meal plans of people with diabetes, it is unlikely that one such combination of macronutrients exists The best mix of carbohydrates, protein, and fat appears to vary depending on individual circumstances Reference American Diabetes Association.

  34. Look AHEAD (Action for HEAlth in Diabetes) is a large clinical trial designed to determine whether long-term weight loss will improve glycemia and prevent cardiovascular events in subjects with type 2 diabetes 1 One-year results of the intensive lifestyle intervention in this trial show an average of 8.6% weight loss, significant reduction of A1C, and reduction in several cardiovascular disease (CVD) risk factors, with benefits sustained at 4 years 2 When completed, the Look AHEAD study should provide insight into the effects of long-term weight loss on important clinical outcomes References Pi-Sunyer X, Blackburn G, Brancati FL, et al, for the Look AHEAD Research Group.

  35. Exercise is an important part of the diabetes management plan Regular exercise has been shown to improve blood glucose control, reduce cardiovascular risk factors, contribute to weight loss, and improve well being 1 Regular exercise may also prevent type 2 diabetes in high-risk individuals 1 A new joint position statement of the American Diabetes Association and the American College of Sports Medicine summarizes the evidence for the benefits of exercise in people with type 2 diabetes 2 Recommendations for physical activity for people with diabetes 3 are summarized on this slide People with diabetes should be advised to perform at least 150 minutes per week of moderate-intensity aerobic physical activity (50-70% of maximum heart rate) (A) In the absence of contraindications, people with type 2 diabetes should be encouraged to perform resistance training three times per week (A) References Knowler WC, Barrett-Connor E, Fowler SE, et al, for the Diabetes Prevention Program Research Group.

  36. Psychological and social problems can impair the ability of the individual 1-3 or the family to carry out diabetes care tasks and therefore compromise health status Opportunities exist for the clinician to assess psychosocial status in a timely and efficient manner so that referral for appropriate services can be accomplished 4 Recommendations for psychosocial assessment and care 4 are summarized on this slide Assessment of psychological and social situation should be included as an on-going part of the medical management of diabetes (E) Psychosocial screening and follow-up should include, but is not limited to, attitudes about the illness, expectations for medical management and outcomes, affect/mood, general and diabetes-related quality of life, resources (financial, social, and emotional), and psychiatric history (E) Screen for psychosocial problems such as depression and diabetes-related distress, anxiety, eating disorders, and cognitive impairment when self-management is poor (C) References Anderson RJ, Grigsby AB, Freedland KE, et al.

  37. Hypoglycemia is the leading limiting factor in the glycemic management of patients with type 1 and insulin-treated type 2 diabetes 1 Recommendations for treating hypoglycemia 2 are summarized on this slide Glucose (15-20 g) is the preferred treatment for the conscious individual with hypoglycemia, although any form of carbohydrate that contains glucose may be used If, after 15 minutes of treatment, SMBG shows continued hypoglycemia, the treatment should be repeated; once SMBG glucose returns to normal, the individual should consume a meal or snack to prevent recurrence of hypoglycemia (E) Glucagon should be prescribed for all individuals at significant risk of severe hypoglycemia, and caregivers or family members of these individuals should be instructed in its administration Glucagon administration is not limited to health care professionals (E) Individuals with hypoglycemia unawareness or one or more episodes of severe hypoglycemia should be advised to their glycemic targets strictly to avoid further hypoglycemia for at least several weeks to reverse hypoglycemia unawareness (at least partially) and reduce risk of future episodes (B) References Cryer PE.

Influenza and pneumonia are common, preventable infectious diseases associated with high mortality and morbidity in the elderly and in people with chronic disease 1 Although studies reporting the morbidity and mortality of influenza and pneumococcal pneumonia specifically in people with diabetes are limited, observational studies of patients with a variety of chronic illnesses, including diabetes, show that these conditions are associated with an increase in hospitalizations for influenza and its complications 1 Safe and effective vaccines are available that can greatly reduce the risk of serious complications from these diseases 1 Recommendations for the immunization of people with diabetes 2 are summarized on this slide Annually provide an influenza vaccine to all diabetes patients ≥6 months of age (C) Administer pneumococcal polysaccharide vaccine to all diabetes patients ≥2 years of age (C) A one-time revaccination is recommended for individuals &gt;64 years of age previously immunized when they were &lt;65 years of age if the vaccine was administered &gt;5 years ago (C) Other indications for repeat vaccination include nephrotic syndrome, chronic renal disease, and other immunocompromised states, such as after transplantation (C) References Smith SA, Poland GA.

  40. Recommendations for the prevention/delay of type 2 diabetes are summarized on this slide Individuals at high risk for developing diabetes (i.e., those with impaired fasting glucose [IFG], impaired glucose tolerance [IGT] or both) can be given interventions that significantly decrease rate of onset of diabetes 1 Based on results of clinical trials and known risks of progression of prediabetes to diabetes, person with an A1C of 5.7%-6.4%, IGT or IFG should be counseled on lifestyle changes: 7% weight loss and moderate physical activity of at least 150 minutes/week Regarding the more controversial issue of drug therapy for diabetes prevention, a consensus panel believed that metformin should be the only drug considered[39] Metformin may be recommended for very high-risk individuals (those with risk factors for diabetes and/or those with more severe or progressive hyperglycemia) Of note, in the Diabetes Prevention Program (DPP), metformin was most effective compared to lifestyle in individuals with BMI ≥35 kg/m 2 and was not significantly better than placebo in those over age 60 years For other drugs, issues of cost, side effects, and lack of persistence of effect in some studies led the panel to not recommend use for diabetes prevention References American Diabetes Association.

  42. Hypertension is a common comorbidity of diabetes that affects the majority of patients, with prevalence depending on type of diabetes, age, obesity, and ethnicity Hypertension is a major risk factor for both CVD and microvascular complications In type 1 diabetes, hypertension is often the result of underlying nephropathy, while in type 2 diabetes it usually coexists with other cardiometabolic risk factors The following eight slides summarize recommendations for screening and diagnosis, goals, and treatment for hypertension/blood pressure control in patients with diabetes Slide 1 of 8 – Screening and Diagnosis Blood pressure should be measured at every routine diabetes visit Patients found to have systolic blood pressure ≥130 mmHg or diastolic blood pressure ≥80 mmHg should have blood pressure confirmed on a separate day Repeat systolic blood pressure ≥130 mmHg or diastolic blood pressure ≥80 mmHg confirms a diagnosis of hypertension (C) Reference American Diabetes Association.

  69. The diabetic neuropathies are heterogeneous with diverse clinical manifestations; they may be focal or diffuse Most common among the neuropathies are chronic sensorimotor diabetic peripheral neuropathy (DPN) and autonomic neuropathy; although DPN is a diagnosis of exclusion, complex investigations to exclude other conditions are rarely needed Early recognition and appropriate management of neuropathy in the patient with diabetes is important for a number of reasons: 1) nondiabetic neuropathies may be present in patients with diabetes and may be treatable; 2) a number of treatment options exist for symptomatic diabetic neuropathy; 3) up to 50% of DPN may be asymptomatic, and patients are at risk of insensate injury to their feet; 4) autonomic neuropathy may involve every system in the body; and 5) cardiovascular autonomic neuropathy causes substantial morbidity and mortality Specific treatment for the underlying nerve damage is not currently available, other than improved glycemic control, which may slow progression but not reverse neuronal loss; effective symptomatic treatments are available for some manifestations of DPN and autonomic neuropathy Recommendations for the screening and treatment of neuropathy in patients with diabetes are summarized in two slides Slide 1 of 2 All patients should be screened for distal symmetric polyneuropathy (DPN) at diagnosis and at least annually thereafter using simple clinical tests (B) Electrophysiological testing is rarely needed, except in situations where the clinical features are atypical (E) Reference American Diabetes Association.

  71. While current standards for diabetes management reflect the need to maintain glucose control as near to normal as safely possible, special consideration should be given to the unique risks of hypoglycemia in young children Glycemic goals may need to be modified to take into account the fact that most children &lt;6 or 7 years of age have a form of “hypoglycemic unawareness,” including immaturity of and a relative inability to recognize and response to hypoglycemic symptoms, placing them at greater risk for severe hypoglycemia and its sequelae In addition, and unlike the case in adults, young children under the age of 5 years may be at risk for permanent cognitive impairment after episodes of severe hypoglycemia In selecting glycemic goals, the benefits on long-term health outcomes of achieving a lower A1C should be balanced against the risks of hypoglycemia and the developmental burdens of intensive regimens in children and youth Recommendations Clinicians should consider age when setting glycemic goals in children and adolescents with type 1 diabetes (E) Reference American Diabetes Association.

  75. Recommendations for the care of patients with diabetes who are admitted to the hospital are summarized on four slides Slide 2 of 4 Goals for blood glucose levels as are follows: Critically Ill Patients Insulin therapy should be initiated for treatment of persistent hyperglycemia starting at a threshold of ≤180 mg/dl (10 mmol/) Once insulin therapy is started, a glucose range of 140-180 mg/dl (7.8-10 mmol/l) is recommended for the majority of critically ill patients (A) These patients require an intravenous insulin protocol that has demonstrated efficacy and safety in achieving the desired glucose range without increasing risk for severe hypoglycemia (E) Selected Patients More stringent goals, such as 110–140 mg/dl (6.1–7.8 mmol/l) may be appropriate for selected patients, as long as this can be achieved without significant hypoglycemia (C) Non-Critically Ill Patients There is no clear evidence for specific blood glucose goals If treated with insulin, premeal blood glucose target should generally be &lt;140 mg/dl (7.8 mmol/l) with random blood glucose &lt;180 mg/dl (10.0 mmol/l), provided these targets can be safely achieved More stringent targets may be appropriate in stable patients with previous tight glycemic control.

  78. 2-CYC10529 Low hypothalamic dopamine release, particularly at the suprachiasmatic nuclei (SCN), is coupled with elevated norepinephrine and serotonin release at the ventromedial hypothalamus (VMH) and each are characteristic neurophysiological features of diabetes This hypothalamic alteration potentiates increases in circulating glucose, free fatty acids and triglycerides, which in turn contribute to insulin resistance in the liver and muscle, and ß-cell dysfunction via lipotoxicity and glucotoxicity. CYCLOSET administration produced a beneficial impact on glucose intolerance in an animal model of type 2 diabetes. Timed pulse CYCLOSET administration both increased SCN (and elsewhere in the CNS) dopaminergic tone and decreased VMH norepinephrine and serotonin release in insulin-resistant animal models. These neurophysiological activities are believed to represent a target-response system responsible for the subsequent multiple downstream biochemical effects of timed CYCLOSET administration in peripheral tissues such as adipose tissue and the liver.
  79. Optional DISCUSSION POINTS: Excessive glucose fluctuations are common in diabetes and are not measured by the A1C. People without diabetes are able to maintain their glucose concentrations within a narrow band (approximately 80 to 140 mg/dL) throughout the day. For patients with diabetes, this level of glucose control is difficult. Even “optimally-treated” patients, whose A1C would predict near target glucose control, can experience wide glucose fluctuations throughout the day. In a recent study, Amylin Pharmaceuticals, Inc. assessed 24-h glucose profiles of 9 subjects with type 1 diabetes whose A1C averaged 6.7% (range of 5.8% to 7.1%), near or within the ADA A1C target range. Subjects used insulin lispro in their insulin pumps. Click: The individual glucose profiles of the 9 patients appear on the graph Despite excellent A1C levels, these patients experienced wide glucose fluctuations throughout the day as measured with continuous glucose monitoring system (CGMS) SLIDE BACKGROUND: CGMS = Medtronic MiniMed Continuous Glucose Monitoring System Mean duration of diabetes for these 9 subjects was 21.5 years (range 2.5 to 40.4 years).
