Monitoring and treatment

for babies and children with alpha-1 antitrypsin deficiency

At the moment there is no specific treatment for A1ATD. Care is usually focused on monitoring and treating any symptoms. Most young children diagnosed with A1ATD will get better and have normal childhoods.

The information on this page is for:

  • Parents of children with A1ATD or suspected A1ATD.
  • Family, friends, carers, and healthcare professionals.

Information about treatment for adults with A1ATD deficiency.

The liver has an amazing ability to grow and repair itself. As your child’s liver grows it should start to work better.

If your child has liver damage their medical team will monitor them and treat any symptoms they have.

They might need some extra support with their diet while they get better. You can find out more about this on the Living with A1ATD page.

In rare cases, if a child has very serious liver damage they may be considered for a liver transplant.

Monitoring for babies and children with alpha-1 antitrypsin deficiency

 

Your child will be monitored to check on their growth and how their liver is doing.

 

Liver monitoring

Doctors will keep an eye on how your child’s liver is doing. This usually involves regular liver blood tests and imaging tests such as ultrasounds.

This could mean lots of hospital visits to start with. As your child’s condition becomes more stable, they should need fewer of these visits.

Growth monitoring

Babies and children with A1ATD may struggle to get enough energy and nutrients from their food. This means they might lose weight or not gain weight normally.

Your medical team will get in touch with your health visitor team. Your baby will probably need to be weighed every week to make sure they are growing well.

Liver transplant

 

In rare cases where the liver damage is very severe then a liver transplant might be needed. If this is going to happen it is usually in the first 2-3 years of life.

Transplants to treat A1ATD have a very good success rate. The new liver will have normal AAT genes. So it will make the normal protein, and your child will not have A1ATD again.

But it is a major operation. Anyone having a transplant will need to be followed up for life. They will also need to take medicines for the rest of their life. These medicines affect how their immune system works.  

Liver transplant is usually only considered if the liver is failing and:

  • affecting a child’s growth, development, and daily life, or
  • causing complications such as ascites and portal hypertension that are getting worse, or
  • the liver has completely failed (fulminant liver failure)
Can I be a liver donor for my child?

A parent or family member can sometimes donate part of their liver to a child who needs a transplant. 

Children needing a transplant due to AATD usually inherit the Z version of the gene from both parents.

Children needing a transplant due to A1ATD usually inherit the Z version of the gene from both parents.

If you have 1 Z version and one normal gene (MZ genotype) then it might be possible to be a donor. But this would only be done if no other possible donor could be found.

If you would like to know more about being a living donor for your child, talk to your medical team.
