Human Normal Immunoglobulin (also known as Intravenous Immunoglobulin, IVIG) is a blood product derived from pooled plasma of healthy donors. It contains a concentrated mixture of antibodies (immunoglobulins) that help the immune system fight infections and modulate immune responses. It is used for a variety of medical conditions, particularly those involving immune deficiencies, autoimmune disorders, and inflammatory conditions.
What is Human Normal Immunoglobulin Used For?
Primary Immunodeficiency Disorders:
Replaces missing or defective antibodies in patients with conditions like:
- Common Variable Immunodeficiency (CVID).
- X-linked Agammaglobulinemia.
- Severe Combined Immunodeficiency (SCID).
Secondary Immunodeficiency:
Used in patients with weakened immune systems due to:
- Chronic lymphocytic leukemia (CLL).
- HIV/AIDS.
- Bone marrow transplantation.
Autoimmune Diseases:
Modulates the immune system in conditions like:
- Immune Thrombocytopenic Purpura (ITP).
- Guillain-Barré Syndrome.
- Chronic Inflammatory Demyelinating Polyneuropathy (CIDP).
- Kawasaki Disease.
Infections:
Provides passive immunity in cases of severe or recurrent infections, especially in immunocompromised patients.
Other Conditions:
Used in some cases of:
- Myasthenia Gravis.
- Dermatomyositis.
- Multifocal Motor Neuropathy.
How Does Human Normal Immunoglobulin Work?
- Replacement Therapy: Provides antibodies to patients who cannot produce their own, helping to prevent infections.
- Immunomodulation: Modulates the immune system by neutralizing autoantibodies, suppressing inflammation, and regulating immune cell activity.
- Reduces Autoimmune Attacks: Modifies immune system overactivity in autoimmune diseases.
Administration Methods:
- Intravenous (IVIG): Administered directly into the bloodstream, typically in a hospital or clinical setting.
- Subcutaneous (SCIG): Administered under the skin, often at home after proper training.
Dosage and frequency depend on the condition being treated, the patient’s weight, and their response to therapy.
Side Effects of IVIG:
Common Side Effects:
- Headache.
- Fatigue.
- Fever or chills.
- Nausea or vomiting.
- Muscle or joint pain.
- Mild allergic reactions (e.g., rash, itching).
Serious Side Effects (Rare but Require Medical Attention):
- Anaphylaxis: Severe allergic reaction (rare but requires immediate medical attention).
- Thromboembolic Events: Blood clots, stroke, or heart attack (especially in patients with risk factors like obesity or a history of clotting disorders).
- Aseptic Meningitis: Inflammation of the brain lining, causing severe headache, nausea, and sensitivity to light.
- Kidney Damage: Rare, but high doses or pre-existing kidney conditions can increase the risk.
- Hemolysis: The breakdown of red blood cells, which can cause anemia.
Important Considerations:
- Screening for IgA Deficiency: Patients with IgA deficiency may develop severe allergic reactions to IVIG. Screening is recommended before starting treatment.
- Infusion Rate: IVIG must be administered slowly to reduce the risk of side effects like headache or anaphylaxis.
- Monitoring: Regular kidney function tests, blood pressure checks, and hemolysis monitoring are essential during treatment.
- Vaccination Considerations: Live vaccines (measles, mumps, rubella, varicella) should be avoided for at least 3 months after receiving IVIG as it may interfere with immune response.
Who Should Avoid Human Normal Immunoglobulin?
- Patients with a history of severe allergic reactions to immunoglobulin products.
- Those with IgA deficiency and anti-IgA antibodies.
- Individuals with severe heart failure or hyperviscosity syndromes.
