Polyclonal Immunoglobulins and Hyperimmune Globulins in Prevention and Management of Infectious Diseases

Immunoglobulin therapy has a rich history of use in preventing and treating infectious diseases; however, clinical data on the efficacy of immunoglobulin is lacking for many infectious diseases. Immunoglobulin therapy is routinely used in postexposure prophylaxis for bacterial infections, including tetanus, botulism, and diphtheria, and viral infections, including hepatitis A and B and varicella. Immunoglobulin therapy has also been used in many severe and life-threatening infections where treatments are limited, including toxic shock syndrome, respiratory syncytial virus infection, and cytomegalovirus infection. The authors review the evidence for the use of immunoglobulin therapy in common adult infectious diseases.
