Cervical human papillomavirus infection in Hangzhou, Jiaxing and Huzhou in Zhejiang province / 中华临床感染病杂志

ABSTRACT

Objective To investigate the prevalence of cervical human papillomavirus (HPV)infection in women with and without cervical lesions in Zhejiang province.Methods Cervical exfoliated cell samples were collected in 865 women with cervical lesions and 630 women with normal cytology from Zhejiang Provincial People's Hospital,Red Cross Hospital of Hangzhou,Maternal and Child Health Hospital of Fuyang City,and the Department of Basic Medical Sciences of Zhejiang Medical College of Zhejiang province.The flow-through hybridization technique (HybriMax) was used to detect 21 kinds of HPV genotypes.x2 and exact test were used for the comparison of HPV infection rates and genotype distributions between women with cervical lesions and those with normal cytology.Results The prevalenceof HPV infection in women with cervical lesions (27.28％,236/865) was significantly higher than that in women with normal cytology (10.32％,65/630) (x2 =65.2,P ＜0.01).In cervical lesion group,60 out of 236 HPV-positive patients (25.42％) were infected with multiple HPVs,including 42 patients infected with 2 genotypes of HPV,12 with 3 types of HPV,5 with 4 types of HPV and 1 with 5 types of HPV ; while in HPV-positive women with normal cytology,only 1 case was infected with multiple HPVs,with a rate of 1.54％ (1/65) (x2 =18.0,P ＜ 0.01).Totally 321 strains (covering 19 HPV genotypes) of HPV were obtained in cervical lesion group,including 188 (58.57％) strains of high-risk,114 (35.51％) strains of low-risk,and 19 (5.92％) strains of other types,and the most prevalent high-risk genotypes were HPV-16,HPV-58,HPV-33,HPV-52 and HPV-39.While in normal cytology group,66 strains (covering 16 HPV genotypes) of HPV were obtained,and the most prevalent genotypes were HPV-52,HPV-16,HPV-31,HPV-58 and HPV-ep8304.Conclusion The prevalence of HPV infection in women with cervical lesions is significantly higher than that in women with normal cytology,and the most prevalent genotypes of infection are HPV-16,HPV-58,HPV-33,HPV-52 and HPV-39.
