Gamma Globulin - Use As Medical Treatment

Gamma globulin injections are usually given in an attempt to temporarily boost a patient's immunity against disease. Being a product derived from blood, gamma globulin injections, along with blood transfusions and intravenous drug use, could pass along Hepatitis C to its recipent. Once Hepatitis C was identified in 1989, blood banks began screening all blood donors for the presence of the Hepatitis C virus in their bloodstreams. However, since the Hepatitis C virus is known to have existed since at least the 1940s, a gamma globulin shot received prior to the early 1990s put the recipient at risk of being infected by the Hepatis C virus.

Injections are most commonly used on patients having been exposed to hepatitis A or measles, or to make a kidney donor and recipient compatible regardless of blood type of tissue match. Injections are also used to boost immunity in patients unable to produce gamma globulins naturally because of an immune deficiency, such as X-linked agammaglobulinemia and hyper IgM syndrome. Such injections are less common in modern medical practice than they were previously, and injections of gamma globulin previously recommended for travelers have largely been replaced by the use of hepatitis A vaccine.

Gamma globulin infusions are also used to treat some immunological diseases, such as idiopathic thrombocytopenia purpura (ITP), a disease in which the platelets are being attacked by antibodies, leading to seriously low platelet counts. It appears that gamma globulin causes the spleen to ignore the antibody-tagged platelets, thus allowing them to survive and function.

A recent clinical trial of gamma globulin in chronic fatigue syndrome patients had no recognizable benefit, while an older trial showed improvement. The success of this treatment remains uncertain.

Another theory on how gamma globulin administration works in autoimmune disease is by overloading the mechanisms that degrade gamma globulins. Overloading the degradation mechanism causes the harmful gamma globulins to have a much shorter halflife in sera.

IVIG may be used in Kawasaki disease.

Intravenous Gamma globulin was FDA-approved in 2004 to reduce antibodies in a patient with kidney failure to allow that person to accept a kidney from a donor with a different blood type (ABO-incompatible), or is an unacceptable tissue match. Stanley Jordan at Cedars-Sinai Medical Center in Los Angeles pioneered this treatment.

Famous quotes containing the words medical and/or treatment:

    Unusual precocity in children, is usually the result of an unhealthy state of the brain; and, in such cases, medical men would now direct, that the wonderful child should be deprived of all books and study, and turned to play or work in the fresh air.
    Catherine E. Beecher (1800–1878)

    The treatment of the incident of the assault upon the sailors of the Baltimore is so conciliatory and friendly that I am of the opinion that there is a good prospect that the differences growing out of that serious affair can now be adjusted upon terms satisfactory to this Government by the usual methods and without special powers from Congress.
    Benjamin Harrison (1833–1901)
