Condyloma acuminatum (CA), or genital wart, is a sexually transmitted infection caused by human papillomaviruses. Increasing evidences demonstrated that photodynamic therapy (PDT) is effective in eliminating latent HPV infection, the major reason for CA recurrence. We observed an increasing number of infections after PDT in CA patients, which has not been reported before. This study aims to evaluate the incidence and management of infection in CA patients after PDT procedure. CA patients received PDT from January 2015 to February 2016 at the outpatient setting. Patients were randomly divided into two groups: the control group and fusidic acid group. Patients in the fusidic acid group used topical fusidic acid (2%) and recombinant human interferon after 5-aminolevulinic acid (ALA)-PDT procedure, while patients in the control group only used recombinant human interferon. Patients came to our department for follow-up evaluations at 4, 8, and 12 weeks after treatment for three times of PDT. Patients with ALA-PDT-associated infection were then randomly divided into two groups: the fusidic acid group and mupirocin group. During the 13-month study period, a total of 718 patients with 2154 times of PDT procedures were enrolled. The infection rate after PDT was 8.5% in the control group, while it was 1.1% in the prophylactic topical fusidic acid group. The cure rate of PDT-associated infection was 85.7% in the fusidic acid group and 86.7% in the mupirocin group. In conclusion, prophylactic topical antibiotic was useful for reduction of PDT-associated infection and optimal wound healing in CA patients.
