[Intravenous Immune Globulin (IVIG)](https://www.fda.gov/vaccines-blood-
biologics/approved-blood-products/immune-globulins) is a solution of human
immunoglobulins specifically prepared for intravenous infusion.
Immunoglobulins contain a broad range of antibodies that act specifically
against bacterial and viral antigens.  
  
 **INDICATIONS:**

  * Treatment of primary immunodeficiency syndromes associated with defects in humoral immunity to replace or boost immunoglobulin G (IgG)
  * Treatment of idiopathic thrombocytopenic purpura (ITP) when a rapid rise in the platelet count is required such as prior to surgery, to control excessive bleeding, or to defer or avoid splenectomy
  * Treatment of Kawasaki disease, in conjunction with aspirin
  * Prevention of recurrent bacterial infections in patients with hypogammaglobulinemia associated with B-cell chronic lymphocytic leukemia (CLL)
  * Decreasing risk of acute graft versus host disease, associated interstitial pneumonia, and infections after bone marrow transplant in the first 100 days after transplantation
  * Reducing the risk of severe bacterial infections in human immunodeficiency virus (HIV) infected children with a CD4 count of greater than 200 to 400
  * Second-line treatment of certain autoimmune myopathies
  * Treatment of adults with Guillain-Barre syndrome diagnosed within the first 2 weeks of illness
  * Treatment of hyperimmunoglobulinemia E syndrome and Lambert-Eaton myasthenic syndrome (LEMS)
  * Treatment of multifocal motor neuropathy (MMN)
  * Treatment of relapsing-remitting multiple sclerosis
  * Treatment of chronic parvovirus B19 infection and severe anemia associated with bone marrow suppression and pure red cell aplasia
  * Treatment of progressive pemphigus vulgaris, pemphigus foliaceus, bullous pemphigoid, mucous membrane pemphigoid, and epidermolysis bullosa acquisita in patients that have failed conventional treatment and patients in whom conventional therapy is otherwise contraindicated
  * For coverage criteria of autoimmune mucocutaneous blistering diseases, please see CMS Internet-Only Manual, Pub. 100-03, Medicare National Coverage Determinations Manual, Chapter 1, Part 4, 250.3
  * Treatment of stiff person syndrome
  * Treatment of myasthenia gravis (MG) in patients who have profound, rapidly progressive and/or potentially life-threatening muscular weakness and are refractory to, or intolerant of cholinesterase inhibitors, corticosteroids and azathioprine
  * Prevention and/or treatment of organ rejection in patients sensitized to living or cadaveric organ donors
  * Schonlein-Henoch
  * Treatment of paraneoplastic visual loss
  * Treatment of chronic inflammatory demyelinating polyneuropathy (CIDP) in patients meeting the necessary criteria
  * Treatment of multiple myeloma for the prevention of life-threatening infections due to reduced gamma globulins

IVIG has been used for many years in the treatment of immunodeficiency
disease. As the knowledge of these diseases has improved and expanded, the use
of IVIG has proportionally grown. With this, the body of literature supporting
the use of IVIG in these situations has equally grown. The literature supports
the use of IVIG in acute situations such as prevention of infections in
patients with solid organ and bone marrow transplants, myeloma, leukemia, and
HIV infections as well as in the acquired and genetic immunodeficiency
syndromes such as CIDP. Additionally, the use in blocking damage by toxic
antibodies in Guillain-Barre syndrome, pemphigus and its variants has been
shown to be effective.

IVIG is an important adjunct or primary treatment in multiple situations where
immunoglobulin abnormalities cause complications because of decreased or toxic
antibodies. As shown in the **_Bibliography,_** there is a significant
literature base to support its use in these situations. This contractor will
continue to monitor the literature for additional uses of IVIG as they
develop.
