Clinical Practice

Updated type 2 diabetes guidelines from the NZSSD

The New Zealand Society for the Study of Diabetes (NZSDD) has published updated guidance on the management of T2D. In the new algorithm, lifestyle management and metformin remain the first-line interventions and the recent shift towards reducing CV and renal risk and obesity are emphasised, in addition to improving glycaemic control. Specific changes to the updated guidance include:

Changes in lifestyle management

• A new emphasis on individualised weight management plans aiming for 10-15% weight loss in early disease to achieve T2D remission

• The emphasis on patient education and support to facilitate self-management has increased

• New section on healthy sleep to improve glycaemic control and weight loss

• Cancer screening and influenza vaccination should be included in wrap-around care

Changes for glucose-lowering medicines

The aim of this section was to recognise ‘off-label’ prescribing given the delay in updating data sheets.

• Metformin dosing does not need to be reduced unless the patient’s eGFR <45 mL/min

• Empagliflozin and/or dulaglutide or liraglutide should be considered in patients aged 10-17 years based on safety and efficacy data*

• Empagliflozin can now be initiated in patients with eGFR >20 mL/min*

• Multiple weekly dulaglutide injections may be considered if the patient is tolerating treatment and has not reached their HbA1c target – the maximum dose is 4.5 mg per week*

• Vildagliptin is redundant if a GLP-1R agonist is introduced and should be withdrawn

• Sulfonylureas and/or insulin can be reduced or withdrawn, where appropriate, when newer agents are introduced

• Liraglutide (Victoza®) is now available under the same Special Authority as dulaglutide – prescribe funded Novofine® or BD® 4 or 5-mm needles

o There is no evidence that either dulaglutide or liraglutide is superior in terms of glycaemic control

o Liraglutide may be preferable if T2D patients cannot obtain or are intolerant to dulaglutide or prefer daily injections Management of hypoglycaemia

• Hypoglycaemia management in T2D has been simplified to prevent both under and over-treatment

o If body weight ≥70 kg take 30 g of rapid acting carbohydrate OR

o If body weight <70 kg take 15 g of rapid acting carbohydrate, repeat after 15 minutes if glucose levels <4 mmol/L Other changes

• The target LDL has been lowered from 1.8 mmol/L to < 1.4 mmol/L

• Lipid-lowering therapy is important to reduce microvascular complications – rosuvastatin is available if LDL cholesterol is above target

• Endorsement of all licenses for Waka Kotahi can now be performed by medical practitioners and diabetes nurse specialists

o Continuous glucose monitoring has been included with targets

o Sulfonylureas are useful for steroid-induced hyperglycaemia

• Acarbose should be taken with meals

Aspirin with or without statins for primary prevention of cardiovascular disease across risk categories

The use of aspirin for the primary prevention of atherosclerotic cardiovascular disease (ASCVD) is controversial and most randomised controlled trial (RCT) evidence favouring its use was conducted before statins were recommended to prevent ACSVD. A meta-analysis was therefore conducted to examine the effect of aspirin in adults without ASCVD, stratified across differing CV risks and according to statin use. RCTs were included of aspirin in patients without ASCVD with followup ≥1 year. The investigators used random-effects models to estimate relative and absolute 5-year risks for CV outcomes, major bleeding, and mortality.

The analysis included 16 trials (n=171,215) reporting on MI and 12 trials (n=163,578) reporting on major bleeding. Aspirin was associated with lower rates of MI (RR 0.85, 95% CI 0.77-0.95; p<0.001) but a higher risk of major bleeding (1.48,1.32-1.66; p<0.001), compared with control. Aspirin was not associated with a reduced risk of stroke or mortality. It was calculated that for every 10,000 adult patients, aspirin reduced MI by 3 events as monotherapy and by 1 event with a statin for very low ASCVD risk patients and reduced events by 49 as monotherapy and by 37 events with a statin for very high risk patients. For major bleeding in every 10,000 patients, aspirin increased the number of events by 21 as monotherapy and by 20 with statins for very low ASCVD risk and by 98 events as monotherapy and by 94 events with a statin for very high risk.

The investigators concluded that in patients without ASCVD, the risk of major bleeding associated with aspirin is greater than the reduction in MI risk across all ASCVD risk levels. Concurrent use of a statin reduces the cardiovascular benefits of aspirin without influencing bleeding risk. Therefore, in patients without ASCVD who are already taking a statin, the addition of aspirin is unlikely to achieve a meaningful CV benefit but would increase the risk of major bleeding.

Thoracic Society of Australia and New Zealand (TSANZ) position statement on chronic suppurative lung disease and bronchiectasis

This position statement from TSANZ updates 2015 guidelines for managing children, adolescents and adults with chronic suppurative lung disease (CSLD) and bronchiectasis. CSLD and bronchiectasis are characterised by a recurrent or long-term productive or wet cough, and infections of the lower airways. In patients with bronchiectasis, bronchial dilation secondary to structural airway injury is present on radiography. The position statement emphasises the importance of early diagnosis for CSLD and bronchiectasis, particularly as early bronchiectasis in young people is now recognised as being potentially reversible. Additional points from the position statement include:

• A diagnosis of bronchiectasis should be confirmed with a chest CT scan, using age-appropriate protocols and criteria in children

• A baseline panel of investigations should be undertaken, which in children and adolescents should include: FBC, major immunoglobulin classes (G,A,M,E), sweat test for chloride testing, culturing airway secretions and spirometry where age appropriate (usually aged >6 years)

• Baseline severity should be assessed along with health impact and individualised management plans developed using a multi-disciplinary approach and co-ordinated care between providers

• Intensive treatment is recommended to improve symptom control, reduce the frequency of exacerbations, maintain lung function, maximise QoL and extend survival. In children, a goal of care is to optimise lung growth and, if possible, reverse bronchiectasis.

• Patients should be taught individualised airway clearance techniques by a respiratory physiotherapist and encouraged to exercise, optimise their nutrition, avoid air pollutants and ensure vaccinations are up to date

• Exacerbations should be treated with a 14-day course of antibiotics as guided by lower airway culture, local susceptibility, clinical severity and patient tolerance. Hospitalisation is recommended for patients with severe exacerbations or those who are not responding to therapy.

• Pseudomonas aeruginosa should be eradicated if it is detected in lower airway cultures

• Treatment with long-term antibiotics, ICS, bronchodilators and mucoactive therapies should be individualised

• Patients should be monitored every 6 months for complications and comorbidities

The concept of ‘treatable traits’ is also highlighted in the position statement whereby clinicians are encouraged to address the individual pulmonary, aetiological, extra-pulmonary, and environmental/lifestyle aspects of each disorder.

FDA updates mammography regulations on reporting of breast density

The U.S. FDA updated its mammography regulations on 9 March 2023. Within 18 months, mammography facilities will be required to notify patients about the density of their breasts to improve physician assessment and categorisation of mammograms.

Dense breasts are a risk factor for developing breast cancer and can also make it more difficult to detect breast cancer on mammograms. In the United States, approximately half of women aged >40 years are described as having dense breast tissue on mammogram. The FDA believes the updated regulations will ensure that patients receive important information that could influence their decision making, such as the need to undergo further evaluation or a repeat mammogram or to increase the frequency of surveillance.

The FDA recommends that patients assessed as having dense breasts talk to their healthcare provider about breast density, risks factors for breast cancer and their individual situation. In New Zealand, patients who undergo mammograms are only told about their breast density if they undertake a private mammogram. Mammograms continue to be recommended as the preferred method of screening for breast cancer and the early detection of the disease.

Global Strategy for Asthma Management and Prevention: updated guidelines

The Global Initiative for Asthma (GINA) published updated guidance on the prevention and management of asthma in May, 2023. The key changes from the 2022 GINA report are:

1. Clarification of asthma medication terminology. For example, the term ‘controller’ has been replaced where appropriate by ‘maintenance treatment’ and use of the term ‘anti-inflammatory reliever’ has been clarified.

2. New commentary has been added to help clinicians explain the asthma management cycle to patients.

3. As-needed combinations of ICS-SABA have been added to the alternative (Track 2) treatment algorithm for adults and adolescents aged >12 years.

4. As needed ICS-formoterol is still the preferred maintenance treatment and reliever for adults and adolescents aged >12 years, despite the addition of ICS-SABA to Track 2 of the algorithm.

5. Practical guidance has been included on dosing medications.

6. The anti-interleukin-5 antibody mepolizumab has been included in the preferred treatment options for children with severe eosinophilic asthma at Step 5.

7. For the sake of clarity, it is explicitly stated that there is insufficient evidence for maintenance treatment at Step 1 in children aged ≤5 years.

8. The use of the term ‘mild’ asthma has been further refined due to differences in common usage and academic definitions. This topic is an ongoing discussion for GINA.

9. GINA recommends biologic therapy only for patients with severe asthma and only if existing treatments have been optimised. This recommendation is regardless of local regulatory approvals.

10. Further details have been provided regarding dosing ICS-formoterol and ICS-SABA during asthma exacerbations. This information has been included in downloadable action plans.

The diagnosis of asthma continues to be an area of interest and discussion for GINA. Recent guidelines have recommended FeNO testing in preference to bronchodilator responsiveness for patients whose lung function pre-bronchodilation is above specified criteria. This recommendation is currently problematic for several reasons, not least that two days of testing would be required given that FeNO must be performed prior to spirometry. GINA has not changed its guidance for diagnostic testing for 2023.

2023 American College of Cardiology (ACC) expert consensus decision pathway on management of heart failure with preserved ejection fraction

Heart failure with preserved ejection fraction (HFpEF) is defined as LVEF ≥50% in combination with signs and symptoms of HF. To estimate the probability of a patient having HFpEF, one of two scoring systems may be used. The H2FPEF (Heavy, 2 or more Hypertensive drugs, atrial Fibrillation, Pulmonary hypertension, Elder age > 60, elevated Filling pressures) algorithm includes hypertension, BMI >30 kg/m2, AF, pulmonary hypertension, age >60 years, and elevated filling pressures, with a score ≥6 being highly suggestive of HFpEF. The HFA-PEFF (Heart Failure Association Pre-test assessment, Echocardiography & natriuretic peptide, Functional testing, Final etiology) algorithm is more complex and comprises pre-test assessment of HF, echocardiography and natriuretic peptide score, functional testing including diastolic stress test/right heart catheterisation, and specialised investigations.

Natriuretic peptides tend to be lower in people who are obese with HFpEF and a high level of suspicion is recommended in obese patients presenting with dyspnoea. Women with HFpEF tend to have worse dyspnoea and reduced health status. Due to concentric remodelling on echocardiogram with greater diastolic stiffness, reduced LV size, and greater LVEF compared to men, an EF of 50-55% in women may be abnormal.

The differential diagnosis of HFpEF may include consideration of non-cardiac causes including renal disease, cirrhosis, and chronic venous insufficiency. Potential cardiac causes that may mimic HFpEF include infiltrative cardiomyopathy, hypertrophic cardiomyopathy, amyloidosis, valvular heart disease, or pericardial disease.

Effectively treating comorbidities is central to the management of HFpEF, including hypertension (systolic BP <130 mmHg), obesity, diabetes, AF, and sleep apnoea. Guidance-directed medical therapy (GDMT) is essential to improve symptoms and functional capacity and to reduce the morbidity and mortality associated with HF. The recommended GDMTs include SGLT2 inhibitors (dapagliflozin*, empagliflozin*), aldosterone antagonists (spironolactone), ARNIs (sacubitril/valsartan†) or ARBs (candesartan). Beta-blockers should be considered for rate control in patients with a history of MI or AF. Diuretics should be used judiciously to reduce congestion and improve symptoms, as needed.

Monitoring pulmonary artery pressure with CardioMEMS™ reduces the risk of hospitalisation for patients with HFpEF. This strategy may not be useful for patients with recurrent hospitalisations or those experiencing changes in volume status.

Comparison of popular dietary programmes and the risk of mortality and cardiovascular events in patients at increased risk

The objective of this network meta-analysis was to determine the relative efficacy of structured diet and health behaviour programmes for the prevention of major CV events and mortality in patients with an increased risk of CVD. Randomised trials were included that compared dietary programmes with minimal intervention, e.g. a healthy diet brochure, or alternative programmes with ≥9 months of follow-up. Dietary programmes were able to include exercise, behavioural support, and antiobesity medications. The outcomes measured were all-cause mortality, CV mortality, and individual CV events.

The study included 40 trials with 35,548 patients across seven named dietary programmes (low fat 18 studies, Mediterranean 12, very low fat 6, modified fat 4, combined low fat and low sodium 3, Ornish 3 and Pritikin 1). There was moderate certainty evidence that Mediterranean diets were superior to minimal intervention for preventing all-cause mortality (OR 0.72, 95% CI 0.56-0.92; 17 fewer per 1000 patients following for 5 years), CV mortality (0.55, 0.39-0.78; 13 fewer per 1000), stroke (0.65, 0.46-0.93; 7 fewer per 1000), and non-fatal MI (0.48, 0.36-0.65; 17 fewer per 1000). Also with moderate certainty evidence, low fat programmes were superior to minimal intervention for preventing all-cause mortality (0.84, 0.74-0.95; 9 fewer per 1000) and non-fatal MI (0.77, 0.61-0.96; 7 fewer per 1000). The patients with the highest CV risk gained the greatest absolute benefits. There were no convincing differences between the low fat and Mediterranean diet in terms of mortality or non-fatal MI. The other five dietary programmes that were assessed were generally found to have little or no benefit compared with minimal intervention.

It was concluded that in patients with increased CV risk, Mediterranean and low-fat diets, with or without exercise or other interventions, reduce all-cause mortality and non-fatal MI. Mediterranean diets are also likely to reduce stroke risk.

Hypertension in pregnancy: updated guidance from NICE

This updated guideline covers the diagnosis and management of hypertension (including pre-eclampsia) during pregnancy, labour and birth. Guidance is also provided to women with hypertension who wish to conceive and women who have experienced a pregnancy that was complicated by hypertension.

Proteinuria in pregnant women should be considered in the context of a full clinical review for pre-eclampsia. If ≥1 urine dipstick test is positive for proteinuria, the albumin:creatinine ratio or protein:creatinine ratio should be used to quantify the proteinuria. First morning voids should not be used to quantify proteinuria.

Women who are taking ACE inhibitors, ARBs or thiazide-like diuretics should be advised that there is a risk of congenital abnormalities if these medicines are taken during pregnancy. An alternative treatment should be discussed with women with hypertension or renal disease. ACE inhibitors or ARBs should be stopped, preferably within 2 days of pregnancy notification. Educate women with hypertension who are breastfeeding that antihypertensives can pass into breast milk, but this would only lead to the baby receiving very low levels that would be unlikely to have a clinical effect. Most medicines are not tested on breastfeeding patients, therefore the disclaimers in the manufacturer’s information are not due to safety concerns or evidence of harm. Enalapril may be preferentially offered as an antihypertensive during the postnatal period, with appropriate monitoring of maternal renal function and serum potassium.

Women who have experienced a hypertensive disorder during pregnancy (including pre-eclampsia) have an approximate 1 in 5 chance of experiencing a recurrence in future pregnancies. Read more here
