ABSTRACT
The Genital warts are common sexually transmitted diseases caused by definite types of human papillomavirus. There are many strategies for the treatment of genital wart and intralesional immunotherapy is considered to be a safe and effective treatment modality. However, there are lack of studies that comparing the clinical effectiveness of intralesional purified protein derivative (PPD) and Candida antigen (CA) in genital wart treatment. To investigate the effectiveness and safety of PPD and CA in the treatment of genital warts. Eighty patients were enrolled in this study and were randomly divided into 2 groups with 40 patients in each. Each antigen was injected intralesionally at a dose of 0.1 ml into the largest wart every 2 weeks until complete improvement or for a maximum of four sessions. Complete clinical response was demonstrated in 65%, 62.5% in PPD and CA groups, respectively. There was no statistically difference between both groups. After the 3-month follow-up period, 72.5%, 85% of patients showed complete clearance in PPD and CA groups respectively. Side effects were mild and insignificant in both groups. Recurrence was observed in only one patient in each group. Immunotherapy by intralesional PPD and CA injection is considered to be effective and well-tolerated modalities in treatment of genital wart with minimal side effects and recurrence rate compared to other modalities.
