[Immunotherapy in virus diseases].

The number of effective anti-viral agents is still limited. Therefore immunotherapy remains of importance in the treatment of viral infections. Immunoglobulins and interferons as well as a variety of immune stimulators or immune modulators are available. The efficacy of such therapy strongly depends on the kind of the virus causing the infection as well as the time of initiation of the treatment. The prophylactic and therapeutic effects of immunoglobulin preparations are well documented, whereas the efficacy of interferons and especially of immune stimulators awaits further evaluation.
