Enzyme Replacement Therapy

Click on the flashcard to see the answer

What is enzyme replacement therapy (ERT)?

Enzyme replacement therapy is a medical treatment that replaces a missing or deficient enzyme in patients with certain metabolic disorders.

Which conditions are commonly treated with enzyme replacement therapy?

ERT is commonly used to treat lysosomal storage diseases like Gaucher disease, Fabry disease, and Pompe disease.

How is enzyme replacement therapy administered?

ERT is often administered intravenously, usually in a clinical setting under medical supervision.

What are some challenges associated with enzyme replacement therapy?

Challenges include immune reactions, high cost of treatment, and limited distribution to certain tissues.

What role do enzymes play in the body?

Enzymes are proteins that act as catalysts, speeding up chemical reactions necessary for cellular functions.

How does ERT address enzyme deficiencies?

ERT provides the missing enzyme directly, allowing normal metabolic processes to occur.

Why can't enzyme replacement therapy permanently cure genetic disorders?

ERT does not correct the underlying genetic mutation causing the enzyme deficiency.

How is the efficacy of enzyme replacement therapy measured?

Efficacy is measured by symptom improvement, biochemical markers, and quality of life assessments.

What are potential side effects of enzyme replacement therapy?

Side effects can include infusion-related reactions, such as rash, itching, and,in rare cases, severe allergic reactions.

Can enzyme replacement therapy be used for all enzyme deficiencies?

Not all enzyme deficiencies are treatable with ERT, as it depends on factors like enzyme stability and delivery to affected tissues.

What advancements are being researched in enzyme replacement therapy?

Researchers are exploring gene therapy and more targeted delivery mechanisms to improve ERT efficacy.

How do patients typically respond to enzyme replacement therapy?

Patient response varies; most see symptom relief, but some may have minimal or adverse reactions.

What is the cost consideration for enzyme replacement therapy?

ERT can be very expensive, often costing thousands of dollars per treatment session.

How does enzyme replacement therapy compare with other therapies for metabolic disorders?

ERT is often more immediate in symptom management but may need to be combined with other treatments for optimal care.

What is a major limitation of current enzyme replacement therapies?

A primary limitation is the inability to effectively deliver enzymes to reach the central nervous system.
