Sinecatechins 10% ointment for genital warts: Case report of a beneficial reaction in an HIV-positive woman

Patients with HIV infection are more likely to develop anogenital warts compared to HIV-negative people and are susceptible to treatment failures and recurrences. We report a case of extensive vulvar warts in an HIV-positive woman successfully treated with sinecatechins ointment. After the failure of a combination of cryotherapy and imiquimod 5% cream, we started therapy with sinecatechins 10% ointment. The patient developed an intense local inflammatory reaction after three weeks that induced the discontinuation of the therapy. After two weeks, we observed a complete regression of inflammation and a reduction of genital warts. The lesions completely regressed within a few weeks, with no relapse after eight months. Sinecatechins is a standardized extract of green tea leaves, effective in the treatment of external genital and perianal warts in immunocompetent patients, but their role has not been yet studied for immunocompromised people. Our case may represent a starting point for further studies, in order to evaluate the relation between treatment dosage, side effects, and drug response in immunocompromised patients.
