Abstract:
Objective To compare the prevalence and genotype distribution of human papillomavirus (HPV) between human immunodeficiency virus (HIV)-positive and-negative populations.Methods Patients with condyloma acuminatum or persons who recently had sexual contact with patients with condyloma acuminatum were enrolled into this study,and classified into HIV-positive group (n =62) and HIV-negative group (n =2 716).GeneChip analysis was performed to detect HPV and determine HPV genotypes in mucocutaneous samples collected from the external genitalia of these subjects.Statistical analysis was carried out by chi-square test using the SPSS software version 19.0.Results The prevalence rates of HPV infection,high-risk HPV types and low-risk HPV types were significantly higher in HIV-positive persons than in HIV-negative persons (74.19％ (46/62) vs.42.30％ (1 149/2 716),67.74％ (42/62) vs.29.57％ (803/2 716),58.06％ (36/62) vs.24.71％ (671/2 716),respectively,all P＜ 0.01).The detection rate of HPV was also increased in HIV-positive men compared with HIV-negative men (92.11％ (35/38) vs.37.38％ (382/1 022),x2 =45.98,P ＜ 0.01).Although the top three genotypes of low-risk HPV were types 6,43 and 11 in both HIV-positive and-negative groups,the prevalence rate of HPV 6 was 37.10％ (23/62) in HIV-positive group,but only 11.12％ (302/2 716) in HIV-negative group.The top five genotypes of high-risk HPV were types 16 (22.58％,14/62),52,66,58 and 18 in HIV-positive group,and types 16 (7.77％,211/2716),58,56,66 and 52 in HIV-negative group.Coinfections with multiple HPV subtypes were common in both groups,and the number of concurrent HPV genotypes was as high as 8 in HIV-positive group,and 9 in HIV-negative group.The prevalence rate of coinfections with three or more HPV genotypes in HIV-positive group was significantly higher than that in HIV-negative group (65.21％ (30/46) vs.16.71％ (192/1 149)).Conclusions Compared with HIV-negative populations,HIV-positive populations show elevated prevalence of HPV infection,high-risk HPV genotypes and low-risk HPV genotypes.Moreover,the prevalence of HPV is higher in HIV-positive men than in HIV-negative men.These findings are worthy of further attention in clinic.
