82963 Glucosidase, beta

Name of the Procedure:

Common Name: Beta-Glucosidase Enzyme Replacement Therapy
Medical Term: Beta-Glucosidase Infusion Therapy

Summary

Beta-Glucosidase enzyme replacement therapy is a medical treatment used to replenish deficient enzymes in individuals with certain metabolic disorders. This infusion helps to break down complex carbohydrates, which are otherwise difficult for their bodies to process due to enzyme deficiencies.

Purpose

This procedure addresses metabolic storage disorders, particularly Gaucher disease, by supplementing the body with the beta-glucosidase enzyme. The goal is to reduce symptoms such as enlarged liver and spleen, bone pain, and fatigue, thereby improving the patient's quality of life and preventing complications.

Indications

• Diagnosed Gaucher disease
• Symptoms of enzyme deficiency such as organomegaly (enlarged liver or spleen), anemia, bone pain, and fatigue
• Documented genetic mutations affecting the beta-glucosidase enzyme

Preparation

• Patients are advised to stay hydrated before the procedure.
• Blood tests and genetic testing are usually required to confirm enzyme deficiency.
• No significant fasting or medication adjustments are typically needed.

Procedure Description

1. The patient is positioned comfortably in a chair or hospital bed.
2. An intravenous (IV) line is inserted into a vein, typically in the arm.
3. The beta-glucosidase enzyme solution is prepared and administered via the IV line.
4. The infusion usually takes about 1-2 hours, during which the patient is monitored for any adverse reactions.
5. The IV line is removed post-infusion, and the patient is observed for a short period.

Tools and Equipment:

• IV setup (needle, tubing, etc.)
• Beta-glucosidase enzyme solution
• Infusion pump (optional, for controlled delivery)

Anesthesia/Sedation:

• Generally not required, though local anesthesia may be used for IV insertion.

Duration

The infusion itself typically takes 1-2 hours, with additional observation time of about 30 minutes.

Setting

• Hospital
• Outpatient clinic

Personnel

• Registered Nurse (RN) or healthcare professional for IV placement and monitoring
• Medical Specialist or Doctor overseeing the treatment

Risks and Complications

Common risks:

• Mild allergic reactions (itching, rash)
• Infusion site reactions (swelling, redness)

Rare risks:

• Severe allergic reactions (anaphylaxis)
• Infusion-related complications (fever, chills)

Management includes pre-medications like antihistamines and steroids to mitigate allergic reactions.

Benefits

• Reduction in symptoms like organ enlargement, bone pain, and fatigue
• Improved organ function
• Enhanced quality of life
• Benefits can start to be seen within a few weeks to months of treatment

Recovery

• Minimal downtime; patients can often return to normal activities shortly after the infusion
• Regular follow-up appointments are essential to monitor progress and adjust dosage
• Patients may need to continue therapy on a regular basis (e.g., every 2 weeks)

Alternatives

• Substrate reduction therapy (oral medications to reduce the buildup of harmful substances)
• Bone marrow transplant (rarely used due to high risks)
• Symptom management with pain relievers and other medications

Pros and Cons of Alternatives:

• Substrate reduction therapy is less invasive but may be less effective.
• Bone marrow transplant might offer a permanent solution but comes with significant risks and a lengthy recovery.

Patient Experience

During the procedure:

• Patients might feel a mild pinch during IV insertion.
• The infusion is generally painless, but some might feel discomfort or mild side effects.

After the procedure:

• Some might experience temporary fatigue or mild flu-like symptoms.
• Pain management is typically not necessary beyond over-the-counter pain relievers for minor discomfort.

Patients are encouraged to report any significant side effects to their healthcare provider immediately. Regular monitoring ensures that any complications can be managed promptly.
