Pulsed-dye laser versus intralesional Candida albicans antigen injection in treatment of genital warts

Acta Dermatovenerol Alp Pannonica Adriat. 2019 Mar;28(1):21-26.


Introduction: Genital warts are a troublesome therapeutic issue. Pulsed-dye laser (PDL) is a non-ablative therapeutic tool for viral warts. Intralesional Candida albicans (C. albicans) immunotherapy has yielded promising results in treatment of various types of warts. We aimed to evaluate the effectiveness of PDL versus C. albicans immunotherapy for treatment of genital warts.

Methods: Forty adult patients with genital warts were divided into two equal groups; the first was treated using PDL and the second using intralesional C. albicans antigen injection. Treatments were performed at 3-week intervals until complete lesion resolution or for a maximum of three sessions.

Results: PDL yielded higher complete clearance rates (95%) than C. albicans antigen (50%; p = 0.001), which in turn had the advantage of treating distant and internal genital warts. Apart from pain during the session in PDL, both modalities were well tolerated with no recurrence in cured patients during the 16-week follow-up period.

Conclusions: PDL and C. albicans antigen injection are safe and effective treatment alternatives for genital warts. PDL yielded better frequencies of clearance, but C. albicans antigen has additional advantages, including a single injection site and treating distant and internal mucosal uninjected warts, which are usually difficult to treat.
