Islet transplantation
- Only patients matching a strict list of criteria, including being at risk of frequent and secere hypos/hypers.

Q

What is the treatment if a STEMI is detected? [3]

A

Open the occluded artery as soon as possible to restore blood flow to the heart (Time is Muscle) (angioplasty) at heart attack centre. less than120 mins is aim

If can’t open artery via stent aim to thromboylse (but want to avoid because have high risk of bleeding).

Reperfusion therapy:
- Aspirin + ticagrelor or pragural (dual antiplatelets)
- Heparin
- PCI

45
Q

What is the treatment if a non- STEMI is detected? [5]

A

A
· Treatment:

o Aspirin + ticagrelor

o +/- GP IIb/IIIa inhibitor (prevent platelet aggregation by blocking glycoprotein IIb/IIIa receptors on their platelet’s)

o Fondaparinux - factor Xa inhibitor

o Anti-ischemic drugs - BB/nitrates

o Angiography, followed by +/- PCI within 24-96 hrs.

· Idea is to thin blood to fit through the semi-occluded gap - then use angiography within 24 hours of presentation to resolve the partial occlusion.

BATMAN

B – Beta-blockers unless contraindicated

A – Aspirin 300mg stat dose

T – Ticagrelor 180mg stat dose (clopidogrel 300mg is an alternative if higher bleeding risk)

M – Morphine titrated to control pain

A – Anticoagulant: Fondaparinux (unless high bleeding risk)

N – Nitrates (e.g. GTN) to relieve coronary artery spasm

Give oxygen only if their oxygen saturations are dropping (i.e. <95%).

Effects of SGLT2 inhibitors? [5]

A

A
Glycosuria: weight loss, reduction in blood glucose, HbA1c reduced

Uric acid reduced

Q

A 76-year-old patient, Eleri, is being investigated by her GP for episodes of dizziness when standing up which is disrupting her daily routine.

What side effect is Eleri most likely to experience?

Depression
Fluid retention
Hyperglycaemia
Osteoporosis
Peptic ulceration

A 76-year-old patient, Eleri, is being investigated by her GP for episodes of dizziness when standing up which is disrupting her daily routine. Eleri is otherwise fit and well and takes no regular medications. Eleri’s GP diagnoses her with orthostatic hypotension and recommends treatment with fludrocortisone.

What side effect is Eleri most likely to experience?

Depression
Fluid retention
Hyperglycaemia
Osteoporosis
Peptic ulceration

Fludrocortisone is a steroid with minimal glucocorticoid activity and high mineralocorticoid activity.

Therefore, fluid retention is the correct answer as this is the side effect listed that is most associated with mineralocorticoid activity

Depression, hyperglycaemia, osteoporosis and peptic ulceration are all side effects associated with glucocorticoid activity.

57
Q

A 63-year-old woman with a history of type 2 diabetes is being reviewed by her general practitioner.

She is currently taking metformin 1g twice daily. She also takes lisinopril for hypertension.

Her latest HbA1c is as follows:

HbA1c 58 mmol/L (more than 42)

After further discussion, she has agreed to add a second anti-diabetic drug to her treatment regimen. She has been advised that side-effects can include weight gain, hypoglycaemia and gastrointestinal upset.

What is the mechanism of action of this drug?

Activation of peroxisome proliferator activated receptor gamma (PPAR gamma)
Binding to KATP channels on pancreatic beta cell membrane
Activation of glucagon-like-peptide-1 (GLP-1) receptor
Inhibition of sodium-glucose co-transporter 2 (SGLT-2)
Inhibition of dipeptidyl peptidase 4 (DPP-4)

Inhibition of dipeptidyl peptidase 4 (DPP-4)

Sulphonylureas exert their effect by binding to KATP channels on the pancreatic beta-cell membrane to stimulate endogenous insulin secretion. This explains the commonly reported side-effects of weight gain (as insulin is an anabolic hormone) and hypoglycaemia.
