Combined treatment of perianal condyloma acuminatum inHIV seropositive men who have sex with men with microwave and photo-dynamic therapy / 中华实验和临床病毒学杂志

ABSTRACT

Objective@#To analyze the clinical features of perianal condyloma acuminatum in HIV infected men who have sex with men (MSM) and assess the effects of combined treatment of microwave and photodynamic therapy.@*Methods@#Clinical and laboratory data of 260 male patients with perianal condyloma acuminatum were collected and microwave combined with photodynamic therapy was applied on them.@*Results@#The majority of the patients with perianal condyloma acuminatum were young people (243/260). Warts were mainly located in the anus or from the outside to inside of the anus (245/260). Among them, the proportion of warts position of extraanal in HIV-infected group (8/220) was lower than that of non-HIV-infected group (7/40). HPV types 11 (70/118), 6 (44/118) and 16 (40/118) were the most common types of HPV infection. People with HIV infection were more likely to develop high-risk, mixed types HPV infection and multiple HPV infection than those without HIV infection. More than half of the patients (146/260) needed only 1-3 sessions of photodynamic treatments. There was no significant difference in the times of photodynamic treatments and the numbers of photosensitizers required between the HIV-infected and non-HIV-infected groups. The recurrence rate of HIV-infected group (13.6%, 30/220) was also similar to that of non-HIV-infected group (15.0%, 6/40), but far lower than those who underwent microwave therapy alone (45%, 18/40).@*Conclusions@#The combination therapy significantly reduced the recurrence rate of perianal condyloma acuminatum in HIV infected MSM.
