Name of the Procedure:

Common Name: Injection of Immune Globulin

Technical/Medical Term: Injection, immune globulin (Privigen), intravenous, non-lyophilized (e.g., liquid), 500 mg (J1459)

Summary

This procedure involves an intravenous infusion of Privigen, a liquid form of immune globulin, which contains antibodies to help the immune system. The injection is typically given in a healthcare setting such as a hospital or clinic.

Purpose

Medical Conditions Addressed:

• Primary immunodeficiency diseases (PIDD)
• Chronic inflammatory demyelinating polyneuropathy (CIDP)
• Other conditions that compromise the immune system

Goals and Expected Outcomes:

• To boost the immune system by providing essential antibodies
• To decrease infection rates
• To improve neurological functions in patients with CIDP

Indications

Specific Symptoms or Conditions:

• Recurrent infections due to immunodeficiency
• Weakness and functional impairment due to CIDP
• Specific allergic and autoimmune conditions requiring immune modulation

Patient Criteria:

• Diagnosed with PIDD, CIDP, or similar conditions
• Requires antibody support determined by a healthcare provider

Preparation

Pre-Procedure Instructions:

• Discuss any allergies and current medications with your healthcare provider
• Follow any dietary or medication instructions (e.g., fasting may not be required but confirm with your healthcare provider)
• Complete any diagnostic tests such as blood work to assess baseline health

Procedure Description

Detailed Steps:

1. Patient is seated or lying down comfortably.
2. An intravenous (IV) line is inserted into a vein, usually in the arm.
3. Privigen is prepared in a sterile environment.
4. The immune globulin is administered slowly through the IV line over a period, which can range from 1 to several hours.
5. Patient is monitored for any immediate reactions.

Tools and Equipment Used:

• IV line and catheter
• Infusion pump or gravity drip setup
• Monitoring equipment for vital signs

Anesthesia or Sedation:

• Typically, no anesthesia or sedation is required.

Duration

The procedure typically takes about 2 to 4 hours, depending on the dosage and patient's response.

Setting

The procedure is usually performed in a hospital, outpatient clinic, or specialized infusion center.

Personnel

• Registered Nurse or Infusion Specialist to administer the IV
• Physician to oversee the procedure and manage any complications
• Support staff for patient comfort and monitoring

Risks and Complications

Common Risks:

• Mild allergic reactions (e.g., rash, itching)
• Headache, dizziness, or nausea during or after the infusion

Rare Risks:

• Severe allergic reactions (anaphylaxis)
• Kidney dysfunction or blood clots
• Aseptic meningitis

Management of Complications:

• Immediate discontinuation if severe reaction occurs
• Supportive treatments such as antihistamines, corticosteroids, or epinephrine for allergic reactions

Benefits

Expected Benefits:

• Enhanced immune function
• Reduced frequency and severity of infections
• Improvement in neurological symptoms for CIDP patients

Timing of Benefits:

• Benefits can be observed within a few days to weeks after the infusion, based on the individual's condition and response.

Recovery

Post-Procedure Care:

• Observation for a short period post-infusion to monitor for delayed reactions
• Drink plenty of fluids to stay hydrated
• Follow any specific instructions from your healthcare team

Expected Recovery Time:

• Most patients can resume normal activities immediately but should avoid strenuous exercises for 24 hours

Follow-up Appointments:

• Regular follow-ups to monitor health status and effectiveness of the treatment

Alternatives

Other Treatment Options:

• Subcutaneous immunoglobulin (SCIG) therapy
• Alternative immunomodulating medications
• Supportive treatments like antibiotics for recurring infections

Pros and Cons:

• SCIG allows for home administration but requires more frequent dosing.
• Alternative medications may have different side effects or efficacy profiles.

Patient Experience

During the Procedure:

• Mild discomfort from the IV insertion
• Possible mild side effects such as chills, fever, or headache

After the Procedure:

• Generally mild post-procedure symptoms such as fatigue
• Pain management might include over-the-counter medications like acetaminophen or ibuprofen

Adequate hydration, rest, and monitoring for any unusual symptoms are essential steps to ensuring comfort and safety during recovery.
