Key points about bronchiectasis

  • bronchiectasis (Bx) is a chest disease - the airways in the lungs have become damaged and scarred
  • mucus gets trapped in pockets in the airway - this causes infections
  • the main symptoms of Bx are a wet sounding cough that lasts for weeks or happens often, and repeated chest infections
  • once your child has Bx, they usually have it for life
  • early recognition and treatment can improve the scarring
  • good care can help your child to stay well with Bx

What is bronchiectasis?

You can't catch Bx or give Bx to anyone

Bronchiectasis (Bx) is a chest disease - the airways in the lungs have become damaged and scarred.

The airways (or breathing tubes) become widened and mucus gets trapped in pockets within the airway. Having extra mucus in the airways means bacteria and viruses can grow quickly and cause infections.

These infections cause damage and more scarring to the airways and lungs. Once this has happened, the scarring is usually lifelong. But, with good treatment, there can be some improvement and further damage prevented. Good treatment is especially important in young children because their lungs are still growing.

Wairingi Koopu (rugby league star):

Can you hear that? This is the sound of a child with chronic persistent wet cough. Scary, isn’t it? Whānau, this is a serious warning sign and should not be ignored. Your child needs urgent medical attention.

What is chronic persistent wet cough?

Dr Cass Byrnes (paediatric respiratory specialist, Starship Hospital):

A chronic persistent wet cough is a mucousy phlegmy fruity-sounding cough. It sounds like the children have got mucus down in their chest and it usually occurs most days and can go on for weeks at a time.

Here is an example.

This cough is not normal and may be a sign that your child has a serious chest infection. It is important that your child sees a doctor as they could develop a serious lung disease.

What happens if chronic persistent wet cough is not treated?

If a chronic persistent wet cough is not treated it can go on for weeks and even months, and it’s a sign that there’s an ongoing chest infection in the lungs and it essentially is causing some permanent scarring in the lungs.

Wairingi Koopu:

Chronic persistent wet cough if left untreated can lead to lung damage and disease such as bronchiectasis.

What is bronchiectasis?

Bronchiectasis is a chest disease in which the breathing tubes called bronchi in the lungs become damaged and enlarged. Tiny hairs called cilia line the inside of these breathing tubes. These hairs help to collect any phlegm or mucus from the lungs.

When your child has bronchiectasis their lungs make more mucus than normal. The tiny hairs that should clear the mucus stop working properly and the mucus gets stuck in the breathing tubes. It is within this extra mucus that germs grow and cause infection.

These infections cause damage and scarring to the breathing tubes and lungs. The breathing tubes become baggy and holes form in the lungs. Once this has happened the scarring and damage cannot be fixed.

What causes bronchiectasis?

Dr Cass Byrnes:

Bronchiectasis is a type of permanent lung scarring which is caused by having ongoing infection in your lungs. That mucus means that there’s mucus and bugs down there and it’s breaking up some of the lung walls and doing lung damage.

What are the symptoms of bronchiectasis?

Wairingi Koopu:

Children with bronchiectasis will feel well most of the time but the main symptom to look out for is the chronic persistent wet cough. This cough produces a build-up of phlegm which may be yellow or green in colour and smelly, showing signs of infection. It is important that you seek medical attention if your child has these symptoms.

What happens if we ignore this symptom?

Dr Cass Byrnes:

Ignoring the chronic persistent wet cough means that you’re going to go on and develop more and more lung scarring. That cough shows that there are problems in the lung. It shows that there is a build-up of mucus, that there is infection and the more and longer that that goes on, the more damage that that lung is going to have permanently lifelong, and set the child up for recurrent further infections.

How can bronchiectasis be prevented?

Wairingi Koopu:

By:

not smoking during pregnancy

breastfeeding our tamariki

early detection and treatment of chest infections in childhood

improving living conditions

eating a healthy balanced diet

immunisation.

We visit the Hiko whānau who deal daily with the effects of having tamariki with bronchiectasis.

Henrietta Hiko (mother of twins):

The illness has changed our lives immensely. I have to give up everything pretty much to go back and forth to the hospital when the girls are sick. They’re sick at the moment but they don’t look it, but I know that they’re sick.

How can a parent manage bronchiectasis? What can they do?

Kimberley Taylor (physiotherapist, Hawkes Bay District Health Board):

Some easy ways that parents can help to manage their tamariki’s bronchiectasis are to get them more active. Exercising outside, running around, on the trampoline, anything that makes them huff and puff, because when you’re huffing and puffing you’re getting air circulating all the way down to the bottom of your lungs and that helps to shift the mucus.

Other things that are really good to help with managing bronchiectasis are to keep your whare auahi kore – so keeping your tamariki smoke-free and telling your whānau to keep outside of the whare when they’re smoking and out of the waka when they’re smoking.

Wairingi Koopu:

If you are concerned about your child's health, please seek medical attention.

Bx is different from asthma but some children with Bx have asthma as well

Causes of bronchiectasis

Common causes

Most children get Bx after having a very bad chest infection or repeated chest infections. Bx usually develops after a child has had:

  • severe bronchiolitis or pneumonia needing a hospital stay
  • chest infections needing repeated antibiotic treatment at home
  • a wet sounding cough lasting for weeks or happening frequently

Less common causes

Problems with fighting off infection. Some children cannot fight infection very well because they are born with a problem in their infection-fighting (immune) system.

Medicines. Some medicines (such as oral steroids) cause difficulty in fighting off infection.

Objects stuck in the airway. If a child breathes in a nut or a piece of a toy and this gets stuck in the airway, it can cause a blockage that can lead to scarring.

Food or liquid going into the lungs (aspiration). Children who sometimes cough or choke when feeding have problems controlling their swallow. Food can end up in their lungs. This can also happen if food refluxes from the stomach and ends up going into the lungs. Over time this can cause Bx.

Primary ciliary dyskinesia. In this condition, the tiny mucus-clearing hairs (cilia) in the lungs are not working properly.

How long bronchiectasis lasts

Once a person has Bx, they usually have it for life. Good treatment stops it getting worse and in very young children, can reverse some of the disease.

How many children get bronchiectasis in New Zealand

  • 1 in 3,000 children gets Bx
  • there is 1 new case of Bx in a New Zealand child every week

Signs and symptoms of bronchiectasis

Children with Bx feel well most of the time.

Wet-sounding cough

A wet-sounding cough is the main symptom and usually lasts for weeks. Extra mucus (phlegm or sputum) in the airways causes the cough and your child may spit or cough up some of this mucus. 

This cough can get worse during infections, first thing in the morning and during exercise. Remember though that exercise and playing sport is helpful for keeping well.

When to help for bronchiectasis

When children with Bx become unwell, they cough more and the mucus can change colour from clear to yellow or dark green. The mucus can sometimes be smelly. They may lose their appetite and feel tired.

When to see a health professional

If your child has Bx, take them to see your health professional when they:

  • have a bad cold with a runny green nose
  • are coughing more than normal
  • have a cough that is wetter than usual
  • have more mucus which is darker, thicker or smelly
  • are breathing faster than normal
  • have a fever
  • have pain in their chest
  • are tired and not eating or drinking as well as normal
  • are unable to take part in sport and exercise

When to see a health professional urgently

Your child is very sick and needs to see a health professional urgently if they:

  • get suddenly more unwell
  • cough up blood

When to call 111

Call 111 within New Zealand (use the appropriate emergency number in other countries) for urgent medical help if your child:

  • is having difficulty talking because they are so short of breath
  • has blue lips or tongue
  • is coughing up a large amount of blood

Tests for bronchiectasis

Chest x-ray

A chest x-ray is usually the first investigation but does not always show Bx damage very well. Your child will probably also need a chest CT scan.

Sputum culture

Your health professional will collect some mucus from your child. Many children will be able to cough some mucus into a jar. Sometimes, a physiotherapist might need to help your child collect a mucus sample.

The mucus is tested for bacteria or viruses. If your child's mucus has bacteria, your doctor will give them the right antibiotic to treat the infection.

Blood tests

Your child will have some blood tests to show that they are able to fight off infection.

Lung function test

Your child will breathe into a machine to measure how their lungs are working. It usually takes about 15 minutes.

Bronchoscopy

A doctor can use a special telescope (bronchoscope) to look into the lungs to see the condition of the airways and take a sample of mucus. This test happens under a general anaesthetic. See some information about anaesthetics

Other tests

Sometimes your child may need other tests such as a sweat test (to look for cystic fibrosis).

Treatment for bronchiectasis

1. Chest physiotherapy

Your child will need chest physiotherapy once or twice a day. There are different ways to do chest physiotherapy - either with breathing and percussion or by using a physiotherapy breathing device (PEP, acapella, bubble). This is to clear the extra mucus from your child's lungs to keep your child well. The physiotherapist will show you the best method to use with your child. The type of chest physiotherapy changes with age.

2. Exercise and sport

Exercise will help your child - it doesn't matter if they cough.

Exercise or playing sport 3 to 4 times a week is helpful to clear the mucus and to develop your child's lungs. Any type of exercise is good, especially if it makes your child take deep breaths. It doesn't matter if your child coughs during exercise.

3. Antibiotics

Your child will need antibiotics if they start to get sick or if they are coughing more. Children with Bx need a longer course of antibiotics (10 to 14 days). Most often, you can give your child antibiotics at home. Sometimes, if your child is very unwell, they may need antibiotics in hospital.

4. Asthma treatment

Some children with Bx may benefit from inhalers because they also have asthma.

5. Bx action plan

Children and young people with Bx can have an action plan. You and your doctor or another member of your child's healthcare team can discuss this so that it's right for your child. It lists your child's daily treatment and steps to take if your child becomes unwell.

Keeping your child with bronchiectasis well

  • regular physiotherapy to keep your child's lungs clear of mucus
  • regular exercise and sport
  • a healthy balanced diet
  • keeping your child away from any cigarette smoke
  • make sure your child gets a flu vaccine every year
  • keeping up with hospital clinic appointments and reviews with your family doctor

If you want to give up smoking, call Quitline 0800 778 778. See the Quit/Me Mutu website, or talk to your health professional.

Health appointments for bronchiectasis

Outpatient clinics

Your child will have regular reviews with the hospital team. The team can include lots of different health professionals. How often the reviews happen depends on how well your child is.

The review will include:

  • height and weight measurement to check growth
  • lung function test to measure how well your child's lungs are working
  • a mucus sample to test for bacteria so your child can get the right antibiotics
  • a cough suction if your child is young and can't cough up mucus
  • a check on how you're going with physiotherapy techniques and whether they need changing

A stay in hospital

If your child has a chest infection that is severe or continues for a long time, they may need to go to hospital for 10 to 14 days to have specialist treatment.

Antibiotics. Your child will have these directly into a vein through a 'drip'. Sometimes your child will have a special drip called a 'PICC line'. This is a long tube which lasts for longer than a 'drip' - it doesn't need replacing regularly.

Chest physiotherapy. A professional physiotherapist will do this twice a day.

Sometimes, your child will have extra testing just like they do at outpatients appointments such as:

  • lung function testing
  • mucus sampling
  • chest x-ray
