To the Editor.—
Antiviral, antiproliferative, and immunomodulating properties make interferons a logical therapeutic approach for anogenital warts. Unlike type I interferons, which have been applied for treatment of anogenital warts in large studies,1 only a few patients, so far, have been treated with systemically administered recombinant interferon gamma.2-5The present study was designed to investigate the efficacy of adjuvant systemic recombinant interferon gamma on the cure rate of surgically removed refractory anogenital warts.
Patients and Methods.—
Twenty patients (16 men and four women; median age, 27 years; age range, 19 to 60 years) suffering from refractory anogenital warts were enrolled in the study between May 1988 and January 1989. Patients had to fulfill the following criteria: multiple visible lesions, age between 18 and 65 years, good general health, disease duration of at least 1 year, failure of at least one traditional treatment, histologic confirmation of the diagnosis,
