Q

what are incretins?

A

Incretins are a group of metabolic hormones that stimulate a decrease in blood glucose levels. Incretins are released after eating and augment the secretion of insulin released from pancreatic beta cells of the islets of Langerhans by a blood glucose-dependent mechanism

Q

What are the guildlines for: GLP-1 ANALOGUES: SIGN & NICE

A

NICE CG87:

  • BMI >35; (Ethnicity; Occupation)
  • Stop after 6/12 unless:
  • HbA1C -1% and Weight - 3% in 6/12

SIGN 154:

  • 3rd line agent; BMI > 30 kg/m2
  • In combination with oral agents and/or basal insulin usually as 3rd or 4th line
  • Stop after 3-6/12 unless HbA1C >5mmol/mol fall or individualized target reached

Q

what are the advantages of GLP1 analogues?

A
  • Weight loss
  • No risk of hypoglycaemia
  • 3rd line agent
  • Can be used with basal insulin
18
Q

what are the disadvantages of GLP1 analogues?

A
  • Injection
  • Very expensive

  • SE: Nausea, vomiting
19
Q

what are examples of SGLT2-inhibitors?

A

…gliflozins

Canagliflozin, Dapagliflozin, Empagliflozin

20
Q

how does SGLT2 inhibitors affect type 2 diabetes?

A

increase excretion of glucose

21
Q

slides showing how SGLT2 inhibitors work:

A

SGLT2 inhibitors, also called gliflozins, are a class of medications that inhibit reabsorption of glucose in the kidney and therefore lower blood sugar. They act by inhibiting sodium-glucose transport protein 2 (SGLT2). SGLT2 inhibitors are used in the treatment of type II diabetes mellitus (T2DM)

22
Q

what are the effects of SGLT2 inhibitors?

A
  • GETS RID OF GLUCOSE / MORE GLYCOSURIA - LOWERS HbA1C
  • GETS RID OF WATER/OSMOTIC DIURESIS - (POSTURAL) HYPOTENSION, DEHYDRATION
  • GETS RID OF CALORIES/WASTES GLUCOSE - LOSE WEIGHT WITH SAME INTAKE
  • GETS RID OF SODIUM/LESS REUPTAKE - LOWERS SYSTOLIC BLOOD PRESSURE
  • GREATER RISK OF UROGENITAL INFECTION - CYSTITIS and CANDIDIASIS
23
Q

When should SGLT-2 inhibitors not be used in regards to renal impairment?

A
24
Q

what are the advantages of SGLT2 inhibitors?

A
  • Weight loss
  • No risk of hypoglycaemia
  • Good effects on glycemic control
  • May have beneficial effect on cardiovascular morbidity & mortality
  • 2nd or 3rd line agent
  • Can add to insulin regimens in T2DM
25
Q

what are the disadvantages of SGLT2 inhibitors?

A
  • Expensive
  • SE: UTI, fungal infections, osmotic symptoms
  • Risk of digital amputation
  • Risk of DKA
  • CI in pregnancy and breastfeeding
  • Cannot use in renal impairment
26
Q

is insulin used in T2D?

A
  • Progressive relative insulin deficiency
  • Use may become ‘inevitable’
  • As many T2 as T1 on insulin

Which regimen? (4T 1yr)

27
Q

What is Supplementary Insulin Therapy in T2D and the effects?

A
  • Easy introduction to insulin
  • Low risk of hypoglyceamia
  • Weight gain?
  • Not quite the last resort – intensification regimens (4T 2-3yr)
  • Which supplementary insulin? once daily normally at bed time

29
Q

what are HbA1c tagrets for people with T2D?

A

For adults with type 2 diabetes managed either by lifestyle and diet, or by lifestyle and diet combined with a single drug not associated with hypoglycaemia, support the person to aim for an HbA1c level of 48 mmol/mol (6.5%)

For adults on a drug associated with hypoglycaemia, support the person to aim for an HbA1c level of 53 mmol/mol (7.0%)

If HbA1c levels are not adequately controlled by a single drug and rise to 58 mmol/mol (7.5%) or higher:

• reinforce advice about diet, lifestyle and adherence to drug treatment and, support the person to aim for an HbA1c level of 53 mmol/mol (7.0%) and, intensify drug treatment

30
Q

Consider relaxing the target HbA1c level on a case‑by‑case basis

what cases would this be in?

A
  • People who are older or frail
  • For adults with type 2 diabetes:
  • With reduced life expectancy
  • high risk of the consequences of hypoglycaemia- those at increased risk of falling, impaired awareness of hypoglycaemia, and people who drive or operate machinery as part of their job
  • intensive management not appropriate- multiple comorbidities
31
Q

What is the 5 step framework for choosing a glucose lowering drug?

A
  1. Set a target HbA1c
  2. “Take 5” Are there other risk factors that should be treated first?
  3. Are the current treatments optimised. Max dose? Tolerated? Taken?
  4. What are the glucose lowering options?
  • Remove any that are contraindicated
  • Of the remaining what are the pros and cons
  • Select the preferred choice
  1. Agree a review date and the target HbA1c with the patient
