Name of the Procedure:

• Common Name: Enzyme Replacement Therapy for LAL-D
• Technical Term: Injection, sebelipase alfa, 1 mg (HCPCS Code J2840)

Summary

Injection, sebelipase alfa, is a procedure used to deliver a synthetic enzyme to patients with Lysosomal Acid Lipase Deficiency (LAL-D), a rare genetic disorder. This procedure involves administering the medication through an intravenous (IV) line to help reduce the buildup of fatty material in the liver and other tissues.

Purpose

• Medical Conditions: Treats Lysosomal Acid Lipase Deficiency (LAL-D).
• Goals: To deliver the enzyme sebelipase alfa to patients to replace the deficient or faulty enzyme, thereby reducing the buildup of harmful substances in the body and improving liver function.

Indications

• Symptoms and Conditions: Indicated for patients diagnosed with LAL-D, confirmed by genetic testing or enzyme activity assays.
• Patient Criteria: Suitable for all age groups diagnosed with LAL-D; assessment by a healthcare professional is required to confirm the need.

Preparation

• Instructions: Patients may be advised to avoid eating or drinking a few hours before the procedure. Medication regimens, including immunosuppressants, may need to be adjusted as per the doctor's advice.
• Diagnostic Tests: Liver function tests, enzyme activity assays, and genetic tests to confirm diagnosis.

Procedure Description

1. Initial Setup: Patient positioned comfortably, an IV line is established.
2. Administration: Sebelipase alfa is prepared and administered via the IV line over a specific period.
3. Monitoring: The patient is monitored for any immediate adverse reactions during the infusion.
   • Equipment: IV line, infusion pump, sebelipase alfa vials.
   • Anesthesia/Sedation: Not typically required; local numbing at the IV site may be used.

Duration

The infusion usually takes about 1 to 2 hours.

Setting

This procedure is typically performed in a hospital, outpatient clinic, or specialized infusion center.

Personnel

• Nurses for IV administration and monitoring.
• Pharmacist for medication preparation.
• Physician to oversee the procedure and manage any complications.

Risks and Complications

• Common Risks: Mild fever, headache, nausea, and redness at the IV site.
• Rare Risks: Allergic reactions, infusion-related reactions, anaphylaxis.
• Management: Close monitoring, availability of medications like antihistamines and epinephrine to manage severe reactions.

Benefits

• Expected Benefits: Improved liver function, reduced hepatic fat accumulation, and overall improvement in health.
• Onset of Benefits: Benefits can be seen within several weeks to a few months.

Recovery

• Post-procedure Care: Observation for any delayed reactions, hydration maintenance.
• Expected Recovery Time: Minimal downtime; normal activities can usually be resumed shortly after the procedure.
• Follow-up: Regular monitoring of liver function and overall health.

Alternatives

• Other Treatments: Dietary modifications, liver transplant.
• Pros and Cons: Sebelipase alfa directly addresses enzyme deficiency, unlike dietary changes which cannot compensate for the genetic defect. Liver transplant, though effective, comes with higher risks and a longer recovery time.

Patient Experience

• During Procedure: Slight discomfort from the IV insertion, generally painless thereafter.
• After Procedure: Minimal pain, most patients experience a quick return to normal activities.
• Pain Management: Mild painkillers may be prescribed if there is any discomfort at the IV site.
