BACKGROUND Identification of human papillomavirus type 16 (HPV16) as the major risk factor for cervical neoplasia, and mass production of DNA free HPV capsids have paved the way to preventive vaccination trials. Design of such trials requires reliable attack rate data. OBJECTIVE Determination of (1) HPV16 and (2) cervical neoplasia attack rates in primiparous women. Estimation of actuarial sa...
Human papillomavirus (HPV)-based cervical screening is a globally recommended health policy. Different HPV types have different risk for cancer. For optimal screening, the sensitivity and specificity each type at viral loads should be known in setting. test results about 1 million samples analyzed during 2006 to 2014 were compared 319 women who had developed invasive cancer up 8.5 years later 1...
BACKGROUND Several serological assays have been developed to detect antibodies elicited against infections with oncogenic human papillomavirus (HPV) type 16. The association between antibody levels measured by various assays and subsequent HPV infection risk may differ. We compared HPV16-specific antibody levels previously measured by a virus-like particle (VLP)-based direct enzyme-linked immun...
To evaluate the effectiveness of Human papillomavirus16/18 infection referral to colposcopy in cervical cancer screening for women aged 25 years and older in Chinese northwest region Shaan'xi province. A total of 2224 women were diagnosed with primary high-risk HPV infection by HPV-DNA genotyping technology during August 2014 to August 2015. A total of 1916 cases referred for colposcopy with hi...
The Costa Rica HPV16/18 Vaccine Trial (CVT) showed that four-year vaccine efficacy against 12-month HPV16/18 persistent infection was similarly high among women who received one, two, or the recommended three doses of the bivalent HPV16/18 L1 virus-like particle (VLP) vaccine. Live-attenuated viral vaccines, but not simple-subunit vaccines, usually induce durable lifelong antibody responses aft...
One half of a group of 20 patients with human papillomavirus type 16 (HPV16)-induced vulvar intraepithelial neoplasia grade 3 displayed a complete regression (CR) after therapeutic vaccination with HPV16 E6/E7 synthetic long peptides. Patients with relatively larger lesions generally did not display a CR. To investigate immune correlates of treatment failure, patients were grouped according to ...
The incorporation of multiple antigens into a single human papillomavirus (HPV) vaccine may induce immune interference. To evaluate whether interference occurs when HPV type 16 (HPV16) virus-like particles are combined in a multivalent vaccine, we conducted a study to evaluate anti-HPV16 responses among subjects receiving three-dose regimens of either a monovalent HPV16 vaccine or a quadrivalen...
High-risk human papillomavirus (HPV) type 16, which is responsible for greater than 50% of cervical cancer cases, is the most prevalent and lethal HPV type. However, the molecular mechanisms of cervical carcinogenesis remain elusive, particularly the early steps of HPV infection that may transform normal cervical epithelium into a pre-neoplastic state. Here, we report that a group of microRNAs ...
BACKGROUND Although cigarette smoking has been associated with increased human papilloma virus (HPV) detection, its impact on HPV DNA load is unknown. METHODS The study subjects were women who were positive for HPV16 and/or HPV18 at enrollment into the Atypical Squamous Cells of Undetermined Significance-Low-grade Squamous Intraepithelial Lesion Triage Study. Assessments of exposure to smoke ...
The characterization of the whole genome of human papillomavirus type 16 (HPV16) from cervical cancer specimens with multiple infections in comparison with single infection samples as the oncogenic potential of the virus may differ. Cervical carcinoma specimens positive for HPV16 by PCR and INNO-LiPA were randomly selected for whole genome characterization. Two HPV16 single infection and six HP...
