Fifty years ago, diphtheria, tetanus, botulism, gas-gangrene, and pneu
mococci were treated using immune globulin from horses, sheeps and oth
er animals. For the first time, Cohn's alcohol fractionation method ma
de it possible to use human immune globulin. On the one hand, immune g
lobulins against bacterial infections became obsolete by the antibioti
cs synchronously developed. On the other hand, human immune globulins
became new therapeutical indications of virus infections, especially o
f hepatitis. Afterwards, the development of intravenous immune globuli
n enabled the therapy of primary or secondary immunodeficiencies. In c
ontrast, the intravenous immune globulin therapy has been reported to
be beneficial during the past decade for numerous autoimmune diseases,
i.e. asthma bronchiale, myasthenia gravis, red-cell aplasia, rheumato
id arthritis, thrombocytopenic purpura, Kawasaki's syndrome, and much
others. There is some evidence for immunomodulation by intravenous imm
une globulin in the same manner as it is well known of the anti-RhD pr
ophylaxis since several decades. Finally, the hepatitis prophylaxis us
ing immune globulin intramuscularly administered is obsolete since an
inactivated hepatitis A vaccine is available.
