[Treatment of female genital condylomatosis with intramuscular beta interferon].

Intramuscular injections of beta-interferon were used to treat a first group of 64 outpatients with clinically diagnosed genital condylomata at single doses of 3 x 10(6) IU for 10 consecutive days. A second group of 30 patients affected by HPV genital infection has been treated with placebo intramuscular injections. Patients were checked at 3, 6 and 12 months after therapy and twice during a one year follow-up after the disappearance of the warts. In the first group 29 patients (45.3%) were cured after 3 months, another 6 after 6 months and 1 patient after one year. In the second group only 3 (10%) patients were cured after 3 months, while in 2 cases (6.7%) lesions disappeared after 6 months (p value less than 0.001). Therapy was most effective on flat lesions in the cervical area. Follow-up of the patients with complete regression of lesions showed three recurrences of condylomatous lesion.
