[Assessment of the formation of antibodies to interferon in patients with juvenile respiratory papillomatosis on interferon therapy].

Children with juvenile respiratory papillomatosis given alpha 2-INF had antibodies to alpha 2-INF in 67.7% of cases. In children treated with intramuscular recombinant alpha 2-INF (reaferon) alone antibodies to INF occurred in 92.3% of patients. The proportion of such patients fell to 28.5% if the children used recombinant alpha 2-INF as rectal suppositories viferon. The level of the antibodies in 4-48 hours decreased 2 times maximally and returned to the baseline on day 3 since intramuscular injection of alpha 2-INF. It is stated that interferon therapy had a positive effect on juvenile respiratory papillomatosis. Antibodies to INF had no negative effects on the treatment results.
