The majority of human papillomavirus (HPV) belong to the genus alpha-papillomavirus, which can be further subdivided into species and then strains. Approximately 200 strains of HPV have been identified, and the whole genomes of approximately 100 strains have been (discovered) and completely sequenced. Between 13 and 18 HPV strains have been characterized as conferring a high oncogenic risk, wit...
BACKGROUND Infection with human papillomavirus (HPV) is the most common sexually transmitted infection among men who have sex with men (MSM). Study on prevalence and risk factors of anal HPV infection among HIV-negative MSM in Northwestern China was rare. METHODS We performed a cross-sectional study of HPV prevalence using anal swab specimens among HIV-negative MSM in Urumqi city of Xinjiang ...
BACKGROUND High-risk human papillomaviruses (HPV) are the main etiological factor of cervical cancer. Cervical intraepithelial neoplasia grade 3 (CIN 3) is the latest pre-invasive stage of cervical cancer, with an approximately 20% progression rate to invasive cervical carcinoma. OBJECTIVE To establish the pre-vaccination distribution of HPV genotypes in Slovenian women with CIN 3 lesions, in...
Background: Human Papilloma viruses (HPV) is the most common sexually transmitted infection (STI) and the most important pathogenic factor for cervical intraepithelial lesions and carcinoma therefore a significant source of morbidity and mortality worldwide. This study was designed to investigate reproductive and medical factors associated with HPV infection in women referred to Colposcopy clin...
Baseline human papillomavirus (HPV) prevalence and type distribution were evaluated in young Chinese women enrolled in a clinical trial of an HPV vaccine (ClinicalTrials.gov registration NCT00779766). Cervical specimens and blood samples were collected at baseline from women aged 18-25 years (n = 6,051) from four sites across Jiangsu province. Cervical specimens were tested for HPV DNA by SPF10...
OBJECTIVE To study the circulation, distribution, and genomic diversity of HPVs in common warts in Beijing area of China. METHODS Forty eight patients with pathologically diagnosed common warts were screened for the presence of HPV with HPV type-specific PCR and direct sequencing analysis. The genomic diversity of HPVs prevalent in Chinese patients was analyzed based on LCR. RESULTS Forty o...
background: cervical cancer has been shown to be highly associated with human papillomavirus (hpv) infection. the viral oncogenes e6 and e7 are constantly expressed by the tumor cells and are therefore potent targets for therapeutic genetic vaccination. in the present study, it was investigated the potential effect of hpv-16 e6, e7 and l1 co-administration to activate specific cytotoxic t lymph...
In order to determine the prevalence of human papillomavirus (HPV) infection in sexually active female population in Messina, we tested cervical scrapes of women referred to university clinics for routine gynaecologic care. Between March and December 2008, a total of 680 cervical samples of 598 patients (573 Italian from province of Messina and 25 resident aliens) were examined consecutively fr...
OBJECTIVE To estimate the incidence and duration of cervical human papillomavirus (HPV)-6, HPV-11, HPV-16, and HPV-18 infections in a population of young American women. METHODS The study population consisted of U.S. women who at baseline were 16 to 23 years of age, reported zero to five lifetime sexual partners, never having been pregnant, and never having had a prior abnormal Papanicolaou t...
This observer-blind study (clinicaltrials.gov NCT01462357) compared the immunogenicity and safety of 2 doses of the HPV-16/18 AS04-adjuvanted vaccine (HPV-16/18(2D)) vs. 2 or 3 doses of the HPV-6/11/16/18 vaccine (HPV-6/11/16/18(2D) and HPV-6/11/16/18(3D)) in healthy girls aged 9-14 y. Girls were randomized (1:1:1) to receive HPV-16/18(2D) at months (M) 0,6 (N = 359), HPV-6/11/16/18(2D) at M0,6...
