Importance of Diagnosis and Management

Gaucher disease type 1 is a rare, progressive condition with many different symptoms. However, it can be managed appropriately.

Potential consequences of delayed diagnosis

When the diagnosis is missed, a patient with Gaucher disease type 1 may experience delays for up to 10 years. Gaucher disease type 1 is progressive and over time may lead to:

Bone problems

Bone pain, death of bone tissue (avascular necrosis), loss of bone mass and bone weakness (osteopenia and osteoporosis), and fractures

Enlarged spleen and liver

Enlarged spleen (splenomegaly) and liver (hepatomegaly)

Lung disease and high blood pressure affecting the lungs and heart

Lung disease and high blood pressure affecting the lungs and heart (pulmonary hypertension)

Bleeding and bleeding complications

Early diagnosis and timely disease management remain important, as damage caused by Gaucher disease type 1 may be irreversible

  • In the short term, therapy may help improve anemia, thrombocytopenia (low blood platelets), hepatomegaly, and splenomegaly
  • Over time, therapy may also prevent the progression of certain Gaucher disease type 1 symptoms

Talking with children about Gaucher disease type 1

A diagnosis of Gaucher disease type 1 can pose unique challenges for children. Some children may find it hard to understand the illness and its effects, especially if it affects their participation in certain activities. If they have started treatment, they may have questions about it.

Offer reassurance
When talking to children about Gaucher disease type 1, the most important thing is to reassure them that illness does not change who they are.

Answer questions according to maturity level
When responding to children’s questions, answers should vary depending on their age and developmental level.

  • For younger children, brief and direct answers to their questions are most helpful. If they want to know more, they will ask
  • Older children may want more detailed information about the disease, its treatment, and how they will be affected

If your child has started treatment, talk to your doctor about what your child might want to know, such as:

  • How will treatment help me?
  • How long is treatment?
  • Will treatment hurt?
  • Can I do other things during treatment?
  • Will I have to miss school or other activities?

Remember, each child responds differently to challenging situations. Reach out to your child’s doctor about how best to support him or her.

Testing for Gaucher disease

Testing for Gaucher disease

A simple blood test can confirm a diagnosis of Gaucher disease. Genetic testing can also be done to additionally confirm a diagnosis, or to identify altered genes and carriers. Although carriers may not have the disease themselves, it’s important to identify them because Gaucher disease could be passed on. Learn more about testing resources at GaucherCare.com.

Suspect Gaucher disease? Talk to your doctor about getting tested. It’s just a simple blood test.

Cerezyme® (imiglucerase) for injection is indicated for treatment of adults and pediatric patients 2 years of age and older with Type 1 Gaucher disease that results in one or more of the following conditions:

  • anemia (low red blood cell count)
  • thrombocytopenia (low blood platelet count)
  • bone disease
  • hepatomegaly or splenomegaly (enlarged liver or spleen)

Important Safety Information


Hypersensitivity and Infusion-Associated Reactions: Serious allergic reactions (anaphylaxis) have been reported in patients treated with Cerezyme. Symptoms suggestive of an allergic reaction have been reported during or shortly after an infusion and include itching, flushing, hives, swelling, chest discomfort, shortness of breath, coughing, cyanosis (a bluish discoloration of the skin due to diminished oxygen), rapid heart rate, and low blood pressure. Inform your doctor and seek medical care if you experience any of these symptoms. If you have had an allergic reaction to Cerezyme, you and your doctor should use caution if you continue to receive treatment with Cerezyme.

Immune Responses: Approximately 15% of patients have developed immune responses (antibodies) to Cerezyme during the first year of therapy. These patients have a higher risk of an allergic reaction (hypersensitivity). Your doctor may periodically test for the presence of antibodies.

Adverse Reactions:
Adverse reactions reported in adults include back pain, chills, dizziness, fatigue, headache, hypersensitivity reactions, nausea, pyrexia, and vomiting.

Adverse reactions reported in pediatric patients 2 years of age and older are similar to adults.
