The results add to the understanding of how immunoglobulin may affect inflammation of the central nervous system in autoimmune inflammatory diseases. Hyperimmune globulin
Hyperimmune globulins are a class of immunoglobulins prepared in a similar way as for normal human immunoglobulin, except that the donor has high titers of antibody against a specific organism or antigen in their plasma. Some agents against which hyperimmune globulins are available include hepatitis B, rabies, tetanus toxin, varicella-zoster, etc. Administration of hyperimmune globulin provides "passive" immunity to the patient against an agent. This is in contrast to vaccines that provide "active" immunity. However, vaccines take much longer to achieve that purpose while hyperimmune globulin provides instant "passive" short-lived immunity. Hyperimmune globulin may have serious side effects, thus usage is taken very seriously.Hyperimmune serum is blood plasma containing high amounts of an antibody. It has been hypothesised that hyperimmune serum may be an effective therapy for persons infected with the Ebola virus. Society and culture
Economics
In the United Kingdom a dose cost the NHS between 11.20 and 1,200.00 pounds depending on the type and amount. Brand names
As biologicals, various trade names of immunoglobulin products are not necessarily interchangeable, and care must be exercised when changing between them. Trade names of intravenous immunoglobulin formulations include Flebogamma, Gamunex, Privigen, Octagam and Gammagard, while trade names of subcutaneous formulations include Cutaquig, Cuvitru, HyQvia, Hizentra, Gamunex-C, and Gammaked.
Medical uses
Immunoglobulin therapy is used in a variety of conditions, many of which involve decreased or abolished antibody production capabilities, which range from a complete absence of multiple types of antibodies, to IgG subclass deficiencies (usually involving IgG2 or IgG3), to other disorders in which antibodies are within a normal quantitative range, but lacking in quality – unable to respond to antigens as they normally should – resulting in an increased rate or increased severity of infections. In these situations, immunoglobulin infusions confer passive resistance to infection on their recipients by increasing the quantity/quality of IgG they possess. Immunoglobulin therapy is also used for a number of other conditions, including in many autoimmune disorders such as dermatomyositis in an attempt to decrease the severity of symptoms. Immunoglobulin therapy is also used in some treatment protocols for secondary immunodeficiencies  such as human immunodeficiency virus (HIV), some autoimmune disorders (such as immune thrombocytopenia and Kawasaki disease), some neurological diseases (multifocal motor neuropathy, stiff person syndrome, multiple sclerosis and myasthenia gravis) some acute infections and some complications of organ transplantation.Immunoglobulin therapy is especially useful in some acute infection cases such as pediatric HIV infection and is also considered the standard of treatment for some autoimmune disorders such as Guillain–Barré syndrome. The high demand which coupled with the difficulty of producing immunoglobulin in large quantities has resulted in increasing global shortages, usage limitations and rationing of immunoglobulin.
