Abstract:
ObjectiveTo determine the genotypes of human papillomavirus(HPV) and to estimate their correlations with recurrence of perianal and anal condyloma acuminatum(CA) among men who have sex with men(MSM) in Shanghai.MethodsTissue specimens were obtained from the lesions of perianal or anal CA in 57 MSM.Flow-through hybridization and gene chip were used to determine the genotypes of HPV in these specimens.Follow-up was carried out to observe the recurrence of CA in these patients after CO2 laser treatment.ResultsOf the 57 specimens,56(98.2％) were positive for HPV,and a total of 11 HPV subtypes were identified.The predominant genotypes were HPV 11 (42 cases,75％ ) and HPV 6 (30 cases,53.6％),sequentially followed by HPV 16 (8 cases,14.3％),HPV 18 (4 cases,7.1％),HPV 33 (2 cases,3.6％),HPV 59(2 cases,3.6％),HPV cp8304 (2 cases,3.6％),HPV 31 (1 case,1.8％) and HPV 35 (1 case,1.8％).Of the HPV-positive specimens,64.3％(36/56) harbored low risk HPV types(11 and/or 6),and 35.7 ％ (20/56) harbored high risk HPV types.Among the 20 specimens positive for high risk HPV,17(85％) harbored both low risk- and high risk-HPV genotypes.During the 6-month follow-up after CO2 laser treatment,recurrence was observed in 95％ of patients with high risk HPV and 66.7％ of patients with low risk HPV (P ＜ 0.05).ConclusionsAmong MSM with perianal and anal CA in Shanghai,the predominant genotypes of HPV are low risk types 11 and 6; high risk HPV infection is usually complicated by low risk HPV infection; the recurrence of CA is higher in patients with high risk HPV than in those with low risk HPV.
