An earlier study by this group failed to demonstrate significant therapeutic effect of 4 weeks of systemic recombinant interferon (IFN)-alpha 2 monotherapy on anogenital condylomata acuminatum. The present study was undertaken to determine if 3 MIU of IFN given three times weekly for 4 consecutive weeks and starting immediately after CO2 laser ablation of all visible warts would be effective. In a multicenter placebo-controlled randomized double-blinded study of 130 evaluatable patients followed for 36 weeks after treatment, no beneficial effects were noted in terms of complete response (24 placebo vs. 23 IFN patients) and recurrences (38 placebo vs. 46 IFN patients). None of the pretreatment and demographic characteristics affected outcome with statistically significant differences. CO2 laser ablation combined with systemic recombinant IFN-alpha 2 was ineffective in this study as treatment of anogenital condylomata.

Male sexual partners of a cohort of women with genital-tract abnormalities which were associated with human papillomavirus infection were examined for evidence of infection with human papillomavirus. Of the 214 male partners who were examined, 93.5% had visible genital lesions. Of the 196 lesions that were biopsied, 72.5% showed histological evidence of infection with human papillomavirus, and only 20.4% of subjects with histological evidence of human papillomavirus were aware of a lesion. An unexpectedly high proportion (6.1%) of lesions on which a biopsy was performed, particularly those with flat, red, indurated morphology, also showed histological evidence of penile intraepithelial neoplasia. This was not significantly more common among the partners of the women with cervical intraepithelial neoplasia than it was among the partners of the women with other evidence of genital human papillomavirus infection. Penile intraepithelial neoplasia was significantly (P less than 0.001) more common among subjects with no history of non-genital warts. We conclude that the male partners of women with human papillomavirus-associated lesions are very likely to be infected with human papillomavirus, and thus may act as a significant reservoir for the reinfection of their female partners. As the awareness of human papillomavirus-associated lesions was low among the male partners, colposcopic examination and treatment of their male partners, and/or barrier contraception, may be a necessary part of the management of women who are undergoing treatment for human papillomavirus-associated genital disease.
