[The treatment with intramuscular interferon of female genital condylomatosis: beta-IFN vs alfa-2a-IFN].

The authors have investigated the efficacy of i.m. therapy with interferon (IFN) in the treatment of female genital condylomatosis: 94 consecutive patients underwent a randomized therapy with two different IFNs: beta-IFN and alpha-2A-IFN (3,000.000 UI i.m. on alternate days for 4 weeks). A total and/or partial response was observed in 76.5% of cases (72/94). Observed response was unrelated with used IFN, independently of type and seat of treated lesion. There was only an important difference between the two treatments in the incidence of side-effects and drop-out (31% and 6.3% with alpha-2A-IFN and 14.8% and 2.1% with beta-IFN). Systemic therapy with IFN is a good alternative to destructive techniques in the treatment of HPV-associated pathology of female lower genital tract.
