Human leukocyte interferon-alpha in cream, for the treatment of genital warts in Asian women: a placebo-controlled, double-blind study.

Abstract

The purpose of this double-blind, placebo-controlled study was to determine and compare the clinical efficacy and tolerance of human leukocyte alpha-interferon (incorporated 2 x 10(6) IU/g) in hydrophilic cream to cure genital warts. Preselected Asian female patients (n = 150) aged 18-40 years (mean 22.5), with the clinical and biopsy-confirmed diagnosis of genital warts (mean 2.64), predominantly flat vaginal condylomas, were randomly allocated to 3 parallel groups. Each patient was given a coded tube containing 80 g placebo/active preparation with a graduated applicator. Patients were instructed to inject 6 g of the either alloted placebo/active cream deep into the vagina thrice a day for 3 consecutive days (group A) or 4 consecutive days (group B) per week, and if not cured the same treatment was extended to 3 more weeks (maximum 4 weeks active treatment). To assess the clinical efficacy patients were examined on a week-to-week basis. A total clearance of warts (biopsy-confirmed) was evaluated as a complete cure. Patients cured during the treatment were spared further treatment and were requested to visit us after 16 weeks for relapse control. As for the remaining patients, empty tubes were collected, and similarly coded replacement tubes were given for further treatment (in total 588 tubes were used). By the end of the treatment 57.2% lesions (227/397) were eliminated in all the groups: 48% patients in group A, 90% patients in group B, and 10% patients in placebo groups taken as completely cured.(ABSTRACT TRUNCATED AT 250 WORDS)
