•DMDM: 6.5% or higher: 6.5% or higher
Values of HbA​​ 1C1C ≥ 7% are a signal
for emergency change in treatment.
Worldwide prevalence of diabetes mellitus
ype 1 DM(beta-cell destruction) – about 10% of all patients.
Autoimmune DM (the so called insulin-dependent DM – IDDM
juvenile-onset diabetes). It results from autoimmune mediated
estruction of the beta cells of the pancreas. The rate of destruction
quite variable (and may reach 80% of the beta- cells of the Langerhans
ets), being rapid in some individuals and slow in others. The
pidly progressive form is commonly observed in children, but also may
ccur in adults. The slowly progressive form generally occurs in adults
nd is sometimes referred to as latent autoimmune DM in adults (LADA).
Idiopathic type 1 DM, which has no known etiology (has no
vidence of autoimmunity). This form is more common among
dividuals of African and Asian origin. Patients periodically
evelop ketoacidosis.
Diabetes mellitus (DM)
Type 2 DM (predominantly insulin resistance with relative insulin
deficiency or predominantly an insulin secretory defect with/without
insulin resistance). DM of this type previously encompassed non-
insulin-dependent diabetes (NIDDM), or adult-onset diabetes. It is
a term used for individuals who have relative (rather than absolute)
insulin deficiency. People with this type of diabetes (> 80% of
patients with DM) frequently are resistant to the action of insulin.
Other specific types of DM
•Genetic defects of beta-cell function (mutations on chromo-
some 12 in a hepatic nuclear transcription factor referred to as
HNF13. A second form is associated with mutations in
the glucokinase gene on chromosome 7p.
•Genetic defects in insulin action (It is connected with
some pediatric syndromes that have mutations in the insulin
receptor gene with subsequent alterations in the insulin receptor
function and extreme insulin resistance).
•Diseases of the exocrine pancreas (pancreatitis, trauma, cancer)
•Endocrinopathies (acromegaly, Cushing’s syndrome,
glucagonoma, and pheochromocytoma).
•Drug- or chemical-induced (pentamidine, glucocorticoids, etc.).
•Viral infections may cause beta-cell destruction (e.g. mumps,
adenovirus, cytomegalovirus, Coxsackie B, congenital rubella).
•Other genetic syndromes sometimes associated with
DM (Down’s, Klinefelter’s and Turner’s syndromes, etc.).
•Gestational diabetes includes the former categories
of gestational impaired glucose tolerance.

Insulin is a protein, secreted
from the β-cells of the islets of
Langerhans in the pancreas
in response to a rise in blood
glucose, and inhibited by a fall.

Insulin
Amylin hypoglycemia
Amylin (Islet Amyloid Polypeptide – IAPP)
reperesents a 37-residue peptide hormone.
It is cosecreted with insulin from the pancreatic
β-cells in the ratio of approximately 100:1.
Amylin plays a role in glycemic regulation by
slowing gastric emptying and promoting satiety,
thereby preventing post-prandial spikes
in blood glucose levels.
Mechanism of action
•Insulin acts via receptors that
are transmembrane
glycoproteins.
•Each receptors has two binding
sites. Receptor occupancy
results in:
1. Activation of insulin-dependent
glucose transport processes in
adipose tissue and muscle.
2. Inhibition of adenylyl cyclase-
dependent processes (lipolysis,
proteolysis, glycogenolysis).
ATP cAMP 3’,5’-AMP
Lipolysis in adipose tissue
(hypercholesterolemia)

4. Intracellular accumulation of
potassium and phosphate
(which are linked to glucose
transport in some tissue).
5. Increased cellular amino acid
uptake, DNA and RNA synthesis.
6. Increased oxidative
phosphorylation.
Insulin is extracted either
from cattle or pig pancreas.
Bovine (B) insulin differs
from human insulin in three
amino acid residues, and
porcine (S) insulin in one,
but their action is very
similar to human. Nobel prize
(1923)
More recently, recombinant
DNA technology has allowed
in vitro manufacturing of insulin
with the same structure as
human (H) insulin.
All current insulin preparations
have a low content of impurities.
Insulin is initially purified by
protein extraction to form a
crystalline product. It may then
undergo either gel filtration to
produce a single peak (SP)
insulin or gel filtration and ion
exchange chromatography
which generates:
•monocomponent (MC),
•single component (SC) and
•rarely immunogenic (RI) insulin.
Other abbreviations
which are used for insulins are:
•Hum- and -man (for human ),
•PP (purified preparation)
MAIN TYPES OF
INSULIN PREPARATIONS
•Short-acting
•Intermediate-acting
(they contain protamin or Zn)
•Long-acting
(they contain both protamin & Zn)
Injectors (with cartridge):
OptiPen, OptiSet, Penfill, etc.

  • 8. Worldwide prevalence of diabetes mellitus
  • 9. ype 1 DM(beta-cell destruction) – about 10% of all patients. Autoimmune DM (the so called insulin-dependent DM – IDDM juvenile-onset diabetes). It results from autoimmune mediated estruction of the beta cells of the pancreas. The rate of destruction quite variable (and may reach 80% of the beta- cells of the Langerhans ets), being rapid in some individuals and slow in others. The pidly progressive form is commonly observed in children, but also may ccur in adults. The slowly progressive form generally occurs in adults nd is sometimes referred to as latent autoimmune DM in adults (LADA). Idiopathic type 1 DM, which has no known etiology (has no vidence of autoimmunity). This form is more common among dividuals of African and Asian origin. Patients periodically evelop ketoacidosis. Diabetes mellitus (DM)
  • 10. Type 2 DM (predominantly insulin resistance with relative insulin deficiency or predominantly an insulin secretory defect with/without insulin resistance). DM of this type previously encompassed non- insulin-dependent diabetes (NIDDM), or adult-onset diabetes. It is a term used for individuals who have relative (rather than absolute) insulin deficiency. People with this type of diabetes (> 80% of patients with DM) frequently are resistant to the action of insulin. Other specific types of DM •Genetic defects of beta-cell function (mutations on chromo- some 12 in a hepatic nuclear transcription factor referred to as HNF13. A second form is associated with mutations in the glucokinase gene on chromosome 7p.
  • 11. •Genetic defects in insulin action (It is connected with some pediatric syndromes that have mutations in the insulin receptor gene with subsequent alterations in the insulin receptor function and extreme insulin resistance). •Diseases of the exocrine pancreas (pancreatitis, trauma, cancer) •Endocrinopathies (acromegaly, Cushing’s syndrome, glucagonoma, and pheochromocytoma). •Drug- or chemical-induced (pentamidine, glucocorticoids, etc.). •Viral infections may cause beta-cell destruction (e.g. mumps, adenovirus, cytomegalovirus, Coxsackie B, congenital rubella). •Other genetic syndromes sometimes associated with DM (Down’s, Klinefelter’s and Turner’s syndromes, etc.). •Gestational diabetes includes the former categories of gestational impaired glucose tolerance.

  • 18. Insulin is a protein, secreted from the β-cells of the islets of Langerhans in the pancreas in response to a rise in blood glucose, and inhibited by a fall. t1/2: 5–6 min molecule mass: 5734 Da t1/2: 5–6 min molecule mass: 5734 DaI. InsulinI. Insulin
  • 20. Amylin (Islet Amyloid Polypeptide – IAPP) reperesents a 37-residue peptide hormone. It is cosecreted with insulin from the pancreatic β-cells in the ratio of approximately 100:1. Amylin plays a role in glycemic regulation by slowing gastric emptying and promoting satiety, thereby preventing post-prandial spikes in blood glucose levels.
  • 21. Mechanism of action •Insulin acts via receptors that are transmembrane glycoproteins. •Each receptors has two binding sites. Receptor occupancy results in:
  • 22. 1. Activation of insulin-dependent glucose transport processes in adipose tissue and muscle. 2. Inhibition of adenylyl cyclase- dependent processes (lipolysis, proteolysis, glycogenolysis).
  • 23. ATP cAMP 3’,5’-AMP Lipolysis in adipose tissue (hypercholesterolemia) AC PD (+) (-)(-) InsulinInsulin
  • 24. 4. Intracellular accumulation of potassium and phosphate (which are linked to glucose transport in some tissue). 5. Increased cellular amino acid uptake, DNA and RNA synthesis. 6. Increased oxidative phosphorylation.

  • 26. Insulin is extracted either from cattle or pig pancreas. Bovine (B) insulin differs from human insulin in three amino acid residues, and porcine (S) insulin in one, but their action is very similar to human. Nobel prize (1923)
  • 27. More recently, recombinant DNA technology has allowed in vitro manufacturing of insulin with the same structure as human (H) insulin. All current insulin preparations have a low content of impurities.
  • 28. Insulin is initially purified by protein extraction to form a crystalline product. It may then undergo either gel filtration to produce a single peak (SP) insulin or gel filtration and ion exchange chromatography which generates:
  • 29. •monocomponent (MC), •single component (SC) and •rarely immunogenic (RI) insulin. Other abbreviations which are used for insulins are: •Hum- and -man (for human ), •PP (purified preparation)
  • 30. MAIN TYPES OF INSULIN PREPARATIONS •Short-acting •Intermediate-acting (they contain protamin or Zn) •Long-acting (they contain both protamin & Zn) Injectors (with cartridge): OptiPen, OptiSet, Penfill, etc.
