What is Gaucher disease?
If you have just
found out that you or your child has Gaucher disease, it is only natural that
you will have many questions and concerns about what to expect. This is a rare
condition that can cause symptoms ranging from weakened bones to easy bruising.
Although there is no
cure, it is important to remember that, depending on the type of illness,
treatment may help you manage some of the symptoms.
Gaucher causes problems with how your body gets rid of certain types of fat. In all
types of this disease, the enzyme needed to break it down does not work
properly. Fat accumulates, especially in the liver, spleleften, and bone marrow,
causing problems.
There are three main
types of Gaucher disease. Type 1 is the most common. If you have it, your
symptoms may be mild, moderate, or severe, but some people don't notice any
problems. There are several treatments for type 1.
Types 2 and 3 are
more serious. Type 2 affects the brain and spinal cord. Infants with type 2
usually do not live beyond 2 years of age. Type 3 also causes damage to the
brain and spinal cord, but symptoms usually appear later in childhood.
Gaucher disease can
have many symptoms, including bloating, bruising, and bleeding.
Your blood may not
clot well, or you may be anemic. It can also cause bone mineral loss, leading
to pain and easy fractures.
The disease is
inherited - about 1 in 450 people of Ashkenazi Jewish origin (from Eastern and
Central Europe) suffer from this disease. This is the most common genetic
disease affecting Jews.
Whether you have the
condition or are the parent of a sick child, it is important to get support to
help you cope with the challenges ahead. Reach out to family and friends for
the support you need. Ask your doctor to join a support group where you can
meet other people who are going through the same thing as you.
Causes
Gaucher disease is
not something that can be “contagious” like a cold or the flu. This is an
inherited disease caused by a problem with the GBA gene.
You get sick when
both parents pass on the damaged GBA gene to you. You can pass the defective
gene on to your children even if you don't have Gaucher disease.
Symptoms
How you feel depends
on the type of Gaucher disease you have.
Type 1. This is the most common form. It usually does not affect the brain or spinal cord.
Type 1 symptoms can
appear at any point in your life, but they usually appear during adolescence.
Sometimes the disease is mild and you will not notice any problems.
Some symptoms you may
experience:
- Easy bruising
- Nosebleeds
- Fatigue
- Enlarged spleen or liver, which makes your belly look swollen
- Bone problems like pain, breaks, or arthritis
Type 2. It affects the brain and spinal cord and is very serious. Babies with this form usually do not live beyond 2 years of age. Symptoms include:
- Slow back-and-forth eye movement
- Not gaining weight or growing as expected, called "failure to thrive"
- High-pitched sound when breathing
- Seizures
- Brain damage, especially to the brain stem
- Enlarged liver or spleen
Type 3. This type also affects the brain and spinal cord. Symptoms are similar to type 2, but usually appear later in childhood and take longer to worsen.
Lethal perinatal Gaucher disease
This is the heaviest type. An infant with
this form usually only lives a few days. These symptoms are overwhelming for a
newborn:
- Too much fluid in the baby's body before or soon after he's born
- Dry, scaly skin and other skin problems
- Enlarged liver and spleen
- Severe brain and spinal cord problems
Cardiovascular Gaucher disease (type 3C)
It is rare and mostly affects your heart.
You may have symptoms such as:
- Hardening of the heart valves and blood vessels
- Bone disease
- Enlarged spleen
- Eye problems
Getting a diagnosis
When you go to your
doctor, he might ask:
- When did you notice your symptoms?
- What's your family's ethnic background?
- Have past generations of your family had similar medical problems?
- Did any children in your extended family pass away before age 2?
If your doctor thinks
it's Gaucher disease, they can confirm it with a blood or saliva test. He will
also do regular tests to keep track of the condition. You may have an NMR scan
to see if your liver or spleen is swollen. You can also have a bone density test
to check for bone loss.
When Gaucher disease
runs in your family, blood or saliva tests can help you determine if you can
pass the disease on to your child.
Questions for the doctor
- Will my symptoms change over time? If so, how?
- Which treatments are best for me?
- Do these treatments have side effects? What can I do about them?
- Is there a clinical trial that could help?
- Are there new symptoms I should watch for?
- How often do I need to see you?
- Are there other specialists I should see?
- Does having this disease put me at risk for any others?
- Should I add my name to a Gaucher disease registry?
- If I have more children, what are the chances they'll have Gaucher disease?
Treatment
The type of treatment
depends on the type of Gaucher disease.
Enzyme replacement
therapy is an option for people with type 1 and some with type 3. It helps
reduce anemia and reduce enlargement of the spleen or liver.
Enzyme replacement
therapy drugs may include:
- Imiglucerase
- Taliglucerase alfa
- Velaglucerase alfa
Other drugs for
treating type 1 are eliglustat (Cerdelga) and miglustat (Zavesca). These are
pills that stop the process of fat formation in the body with a lack of
enzymes.
No treatment can
prevent type 3 brain damage, but researchers are always looking for new ways to
fight the disease.
Other treatments that
may relieve your symptoms include:
- Blood transfusions for anemia
- Medications to strengthen your bones, prevent the buildup of fat, and ease pain
- Joint replacement surgery to help you move better
- Surgery to remove a swollen spleen
- Stem cell transplant to reverse type 1 symptoms. This procedure is complicated and can cause both short-term and long-term problems, so it's rarely used.
What to expect
Since each person's
illness is different, you should consult with your doctor to make sure you are
receiving the proper treatment. Treatment can help you feel better and live
longer.
You may consider
participating in a clinical trial. Scientists are using them to study new
treatments for Gaucher disease. These trials test new drugs to make sure they
are safe and work. They are often a way to try new drugs that are not available
to everyone. Your doctor can tell you if any of these tests are right for you.
If your child is Gaucher, he may not grow as fast as other children. He may be late for
puberty.
Depending on your
symptoms, you may need to avoid contact sports or limit your activity. Some
people suffer from severe pain and fatigue. It may take extra effort to be
active. However, small things can make a big difference. For example,
wheelchairs or crutches can help you when you have difficulty walking. Daytime
naps are also helpful.
If you have severe
symptoms, you may need regular care and be unable to live on your own.
Whether you have a
medical condition or are caring for someone with it, it's hard to deal with.
When you get support from other people facing the same problems, it can help
you feel less isolated. Sharing information and advice can make your daily life
easier.
Consider getting professional advice. It can also help you deal with your feelings and frustrations about Gaucher disease.
