[Condylomata acuminata--topical and systemic interferon therapy].

An open study was carried out to test the effect of systemic administration of interferon (IFN) gamma and local application of IFN beta as monotherapy and adjuvant treatment. The topical application of IFN beta gel had no effect as monotherapy and when it was given as adjuvant therapy the rate of recurrence was not significantly reduced. IFN gamma was given for monotherapy in two different doses (100 and 200 micrograms per s.c. injection). The response rate to the cyclic treatment was 45% in the group (20 patients) receiving a dosage of 100 micrograms, and 57% in the group (26 patients) receiving a dosage of 200 micrograms. Patients with a duration of the disease longer than 18 months and patients with immune deficiency did not respond to the monotherapy. A group of 15 patients with resistant genital warts received adjuvant treatment with IFN gamma over 7 days after surgical treatment. In patients with inconspicuous immune status it was possible to reduce the recurrence rate.
