Anti-infectious serotherapy has been progressively abandoned, due to t
he development of potent antibiotics, and because of its bad tolerance
and weak efficacy, except in rare indications, mainly for prevention.
Many reasons have lead to reconsider immune therapy in the prevention
and/or in the treatment of some infectious diseases: monoclonal human
ized antibodies, emergence of multiresistant bacteria, lack of efficac
y of anti-microbial agent (especially in some viral infections), a hig
h death rate for septic shock and infection in immunocompromised hosts
in spite of modern antibiotics. Immunoglobulins can be prescribed as
monotherapy or in combination with antimicrobial agents.
