Monitoring of patients treated with interferons

Interferon alpha (IFN-alpha) and interferon beta (IFN-beta) have been used for treating many disorders with widespread clinical effects. However, like many other proteins, all IFN species are potentially immunogenic, particularly those produced by recombinant gene technology. The reported frequencies and titers of anti-IFN antibodies varies significantly depending on various diseases, IFN preparations and administration, and the type of method used for detection of antibodies. Antibody-mediated decreased bioactivity of IFN (ADB) is increasingly recognised as a condition in which the clinical effect of prolonged continuous treatment with IFN is decreased or abolished. Wieslab has chosen to use a method that measures neutralizing antibodies (NAbs) against biological active interferon which is considered therapeutic significant.
