Objectives and background for this learning resource

Introduction:

This learning resource has been developed as part of a medical education initiative supported by Janssen. The content of this slide kit has been developed by an advisory board of renal physicians, GPs and specialist nurses. The panel of experts includes members of the British Renal Society Chronic Kidney Disease (CKD) Strategy Group. Bedrock Healthcare, a medical communications agency, has provided editorial support in developing the content; Janssen has reviewed the content for technical accuracy.

Educational objectives:

• To provide clear and applicable clinical guidance on chronic kidney disease (CKD) in people with type 2 diabetes to primary care healthcare professionals

• To advise primary healthcare professionals on what people with diabetes need to know about their own condition with relation to CKD

Usability objectives:

• To provide essential, relevant and up to date information in concise presentations

• To enable primary healthcare professionals to locate, select and use the content of the learning resource, as appropriate to their needs

• To enable secondary care experts in CKD to refer their primary care colleagues to the resource

Section F – 3 key learning objectives

• Once diabetic kidney disease has developed, early optimal management can reduce disease progression

• ACE inhibitors and ARBs improve outcomes

• Presence of diabetic kidney disease implies generalised vascular disease which requires holistic management

Page 6: These slides were sponsored by Janssen and developed in conjunction with the BRS CKD Strategy Group, following an advisory board that was organised by.

ACE inhibitors or ARBs for blood pressure management

• Angiotensin-converting enzyme (ACE) inhibitors and angiotensin-receptor blockers (ARBs) are both renin–angiotensin–aldosterone system (RAAS) antagonists1

• Only one type of RAAS agonist should be offered to people with CKD

– Combined therapy of ACE inhibitors and ARBs is not recommended1

Hypoglycaemia is a risk for patients with type 2 diabetes and CKD when taking oral glucose control therapies

• Progressive CKD increases the risk of hypoglycaemia1,2

• With impaired kidney function, the half-life of insulin is prolonged1,3

• Risk of ‘hypos’ may be more difficult to predict in patients with CKD*

• Symptoms of ‘hypos’ may be reduced in patients with CKD*

• Assess ‘risk and treatment’of hypoglycaemia1,2

• More tailored dosing is required1

• Patients need to be monitoredmore frequently1

Perform frequent therapy reviews, especially if patient

commences dialysis*

Always ask about

hypoglycaemia*

Importance of testing for anaemia and monitoring HbA1c levels carefully

• People with CKD are often anaemic, particularly if eGFR <45ml/min/1.73 m2 (GFR category G3b, G4 or G5)1

• Patients with anaemia (defined as Hb <110g/L):1,2

– Have shortened red blood cell (RBC) lifespan (~ 90 days), which reducesHbA1c levels3

– Have iron deficiency, which increases HbA1c (false high)4

– Are often receiving IV iron therapy or erythropoiesis-stimulating agents (ESA),both of which can reduce HbA1c in patients with diabetes and CKD5

• It is important to test for anaemia in patients with CKD and monitor HbA1c levels carefully

Glucose control therapies in type 2 diabetes and CKD (1 of 4)

Medication Recommended use in renal impairment

Metformin • ADULT and CHILD >10 years initially 500 mg with breakfast for at least 1 week then 500 mg with breakfast and evening meal for at least 1 week then 500 mg with breakfast, lunch and evening meal; usual max. 2 g daily in divided doses1

• Use with caution in renal impairment, avoid in significant renal impairment1

• Determine renal function before treatment and at least annually (at least twice a year in patients with additional risk factors for renal impairment, or if deterioration suspected) 1

• NICE recommends dose review if eGFR <45 mL/minute/1.73 m2, avoid if eGFR <30 mL/minute/1.73 m2

• Withdraw or interrupt treatment in those at risk of tissue hypoxia or sudden deterioration in renal function, such as those with dehydration, severe infection, shock, sepsis, acute heart failure, respiratory failure or hepatic impairment, or those who have recently had a myocardial infarction1

DPP4 inhibitors • Alogliptin1

– Reduce dose to 12.5 mg OD if eGFR 30–50 mL/minute/1.73 m2

– Reduce dose to 6.25 mg OD if eGFR <30 mL/minute/1.73 m2 and use with caution• Linagliptin1

Insulin in CKD

• Insulin resistance and reduced clearance of insulin can lead to swings in glycaemic levels1

• Insulin therapy requirements may reduce as kidney function declines due to:

– The effect of reduced kidney function on insulin clearance2,3

– Reduction of gluconeogenesis in the kidney3

– Uraemia-induced anorexia and weight loss3

• There are no evidence-based guidelines or recommendations about which types of insulin to use or avoid depending on the severity of CKD2

– Some studies suggest avoiding long-acting insulin, whereas others support its use2

• Frequent monitoring is advised2,4

Dialysis can effect glycaemic control and the risk of hypoglycaemic events

• Haemodialysis can affect glycaemic control in the following ways:1

– Improves insulin sensitivity

– Improves insulin clearance

• Insulin requirements may be 25% lower the day after dialysis compared with the day before.1 Mean blood glucose is lower on dialysis days2

• Inadequate gastrointestinal glucose absorption (due to gastroparesis) canalso negatively influence glycaemic control in patients with diabetes undergoing dialysis3

• Therefore in patients receiving dialysis there is a clear need to review:

– HbA1c trends4

– Current medication4

– HbA1c levels, with regards to reliability of results5

• Suspect kidney disease other than diabetic nephropathy and consider further investigation or referral when the albumin:creatinine ratio (ACR) is raised and ANY of the following apply:1

– There is no significant or progressive retinopathy1

– Blood pressure is particularly high or resistant to treatment1

– The person previously had a documented ACR <3mg/mmol and develops heavy proteinuria (ACR >100 mg/mmol)1

INVOKANA®

film-coated tablets PRESCRIBING INFORMATION. ACTIVE INGREDIENT(S): Canagliflozin hemihydrate, equivalent to

100 mg or 300 mg canagliflozin. Please refer to Summary of Product Characteristics (SmPC) before prescribing. INDICATION(S): In

adults with type 2 diabetes mellitus to improve glycaemic control as: monotherapy when diet and exercise alone do not provide

adequate glycaemic control and use of metformin considered inappropriate; add-on therapy with other glucose-lowering medicinal

products including insulin, when these, together with diet and exercise, do not provide adequate glycaemic control. DOSAGE &

ADMINISTRATION: Adults: recommended starting dose: 100 mg once daily. In patients tolerating this dose and with eGFR ≥ 60

mL/min/1.73 m2

needing tighter glycaemic control, dose can be increased to 300 mg once daily. Caution increasing dose in patients ≥

75 years old, with known cardiovascular disease or for whom initial canagliflozin-induced diuresis is a risk. Correct volume depletion

prior to initiation. When add-on, consider lower dose of insulin or insulin secretagogue to reduce risk of hypoglycaemia. Children: no

data available. Elderly: consider renal function and risk of volume depletion. Renal impairment: not to be initiated with eGFR < 60

mL/min/1.73 m2

. If eGFR falls below this value during treatment, adjust or maintain dose at 100 mg once daily. Discontinue if eGFR

persistently < 45 mL/min/1.73 m2

. Not for use in end stage renal disease or patients on dialysis. Hepatic impairment: mild or moderate

hepatic impairment: no dose adjustment. Severe hepatic impairment: not studied, not recommended.

CONTRAINDICATIONS: Hypersensitivity to active substance or any excipient.SPECIAL WARNINGS & PRECAUTIONS: Not studied in

patients with type 1 diabetes. Not to be used for treatment of diabetic ketoacidosis. Renal impairment: eGFR < 60 mL/min/1.73 m2

:

higher incidence of ADRs associated with volume depletion particularly with 300 mg dose; more events of elevated potassium; greater

increases in serum creatinine and BUN; limit dose to 100 mg once daily and discontinue when eGFR < 45 mL/min/1.73 m2

. Not studied

in severe renal impairment. Monitor renal function prior to initiation and at least annually. Volume depletion: caution in patients for

whom a canagliflozin-induced drop in blood pressure is a risk (eg, known cardiovascular disease, eGFR < 60 mL/min/1.73 m2

, anti-

hypertensive therapy with history of hypotension, on diuretics or elderly people). Not recommended with loop diuretics or volume

depleted patients. Monitor volume status and serum electrolytes. Elevated haematocrit:caution. Genital mycotic infections: risk in

male and female patients, particularly in those with a history of GMI. Urine laboratory assessment: glucose in urine due to mechanism

of action.

Lactose intolerance: do not use in patients with galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption.

SIDE EFFECTS: Very common: hypoglycaemia in combination with insulin or sulphonylurea, vulvovaginal candidiasis. Common:

constipation, thirst, nausea, polyuria or pollakiuria, urinary tract infection, balanitis or balanoposthitis, dyslipidemia, hematocrit

increased.Uncommon: dehydration, postural dizziness, syncope, hypotension, orthostatic hypotension, rash, urticaria, bone fracture,

blood creatinine increased, blood urea increased, blood potassium increased, blood phosphate increased. Refer to SmPC for other

side effects. PREGNANCY: No human data. Not recommended. LACTATION: Unknown if excreted in human milk. Should not be used

during breast-feeding. INTERACTIONS: Diuretics: may increase risk of dehydration and hypotension. Insulin and insulin

secretagogues: risk of hypoglycaemia; consider lower dose of insulin or insulin secretagogue. Effects of other medicines on

Invokana: Enzyme inducers (eg, St. John’s wort, rifampicin, barbiturates, phenytoin, carbamazepine, ritonavir, efavirenz) may decrease

exposure of canagliflozin; monitor glycaemic control. Consider dose increase to 300 mg if administered with UGT enzyme inducer.

Cholestyramine may reduce canagliflozin exposure; take canagliflozin at least 1 hour before or 4-6 hours after a bile acid sequestrant.

Effects of Invokana on other medicines: Monitor patients on digoxin, other cardiac glycosides, dabigatran. Inhibition of Breast Cancer

Resistance Protein cannot be excluded; possible increased exposure of drugs transported by BCRP (eg, rosuvastatin and some anti-

cancer agents). Refer to SmPC for full details of interactions. LEGAL CATEGORY: POM PRESENTATIONS, PACK SIZES,
