85250 Clotting; factor IX (PTC or Christmas)

Name of the Procedure:

Clotting; Factor IX Replacement Therapy (PTC or Christmas Factor)

Summary

Factor IX replacement therapy involves the intravenous administration of clotting factor IX, either derived from human plasma or produced via recombinant technologies, to treat or prevent bleeding episodes in individuals with factor IX deficiency, commonly known as Hemophilia B or Christmas disease.

Purpose

Factor IX replacement therapy addresses Hemophilia B, a genetic disorder that impairs the blood's ability to clot. The primary goal is to prevent or control bleeding episodes, reduce the risk of joint damage from bleeding, and improve overall quality of life.

Indications

• Diagnosed with Hemophilia B (Factor IX deficiency)
• Experiencing acute bleeding episodes
• Prior to surgical or dental procedures to prevent bleeding
• Regular prophylactic treatment to prevent spontaneous bleeding

Preparation

• No fasting typically required
• Adjustments to regular medications as advised by a healthcare provider
• Blood tests to determine baseline factor IX levels and to monitor liver and kidney function

Procedure Description

1. The patient is positioned comfortably and an intravenous (IV) line is established.
2. Factor IX concentrate is reconstituted with sterile water if necessary.
3. The solution is administered slowly via the IV line over a specified period, typically a few minutes.
4. The healthcare provider monitors the patient for any immediate adverse reactions.

Tools/Equipment:

• Sterile IV catheter or infusion set
• Reconstituted factor IX concentrate
• Sterile syringes and antiseptic wipes

Anesthesia/Sedation:

• Not typically needed unless the patient has severe needle phobia or the procedure involves young children, in which case mild sedation may be considered.

Duration

The actual infusion of factor IX concentrate usually takes about 5 to 10 minutes.

Setting

Typically performed in a hospital outpatient clinic, infusion center, or sometimes at home by the patient or a caregiver after proper training.

Personnel

• Hematologist or a specialized nurse for infusion
• General nurses for setting up the IV and monitoring
• Emergency medical personnel on standby if the infusion takes place in a clinical setting

Risks and Complications

Common:

• Mild allergic reactions (rash, itching)
• Headache

Rare:

• Severe allergic reactions (anaphylaxis)
• Development of inhibitors (antibodies against factor IX)
• Blood-borne infections from plasma-derived products (minimized in recombinant products)

Benefits

• Immediate reduction in bleeding symptoms
• Prevention of chronic joint damage and other complications associated with bleeding
• Improved quality of life and mobility

Recovery

• Minimal recovery time needed
• Patients may resume normal activities shortly after the procedure
• Regular follow-up appointments to monitor factor levels and adjust dosing

Alternatives

• Desmopressin (not effective for Hemophilia B)
• Antifibrinolytic agents (e.g., tranexamic acid) for mild bleeding episodes
• Gene therapy (experimental at this stage)
• Plasma-derived factor IX concentrate (alternative to recombinant products)

Pros and Cons:

• Factor IX replacement is currently the most effective and reliable treatment.
• Gene therapy shows promise for long-term relief but is not yet widely available.

Patient Experience

• Mild discomfort at the injection site
• Monitoring for reactions during the infusion
• Temporary mild side effects like headache or dizziness
• Education on recognizing and responding to signs of complications Pain Management and Comfort Measures:
• Topical anesthetic cream for needle insertion site
• Warm compresses and gentle movement to ease any stiffness after infusion
