Serum samples from 194 cases and 217 controls participating in a case-control study of invasive cervical cancer in Brazil were examined for antibodies to human papillomavirus (HPV) 16 virus-like particles (VLPs) by ELISA. The prevalence of antibody in cases and controls was 47.4 versus 24.4% (P < 0.001). The prevalence was higher in women who had HPV-16 DNA in the genital tract (54.2%) than in ...

Human papillomavirus type 16 (HPV-16) is strongly associated with the development of cervical cancer. Studies of model systems with animal papillomaviruses have demonstrated the importance of neutralizing antibodies in preventing papillomavirus-associated disease. The assessment of neutralizing antibody responses against HPV-16, previously hampered by the lack of a viral source, was enabled by ...

Human papillomavirus (HPV)-16 causes about half the cases of cervical cancer worldwide and is the focus of HPV vaccine development efforts. Systematic data are lacking as to whether the prevention of HPV-16 could affect the equilibrium of infection with other HPV types and thus alter the predicted impact of vaccination on the occurrence of cervical neoplasia. Therefore, the associations of HPV-...

BACKGROUND This study was performed to compare the prevalence of HPV infection and high risk HPV genotypes [16, 18] between monogamous and polygamous women, in Zabol, Iran. METHODS This cross sectional study was conducted in Zabol in 2006 - 2007. Two hundred sixty five married women attending the Gynecology Clinic for Cervical Disease Screening entered to this study. One hundred sixty two cas...

OBJECTIVE Infection with high-risk genotypes of human papillomavirus (HR-HPV) is the major cause of invasive cervical cancers. HPV-16 and HPV-18 are known to be responsible for two-thirds of all invasive cervical carcinomas, followed by HPV-45, -31, and -33. Current guidelines only differentiate HPV-16/18 (+) by recommending direct colposcopy for treatment. We tried to evaluate whether there ar...

OBJECTIVE In most cervical cancers, human papillomaviruses (HPVs) are identified. The E6 and E7 genes of HPVs encode proteins, that interfere with the function of the tumor suppressor proteins p53 and Rb. We are exploring the potential use of antisense HPV RNA transcripts for gene therapy for HPV-positive cervical cancers. METHODS Via a recombinant adenoviral vector, Ad5CMV-HPV 16 AS, we intr...

BACKGROUND A majority of studies have implicated the involvement of cigarette smoking in cervical cancer development, although its mechanism of action remains unclear. We conducted a large population-based case-control study to address the potential interaction between smoking and human papillomavirus type 16 (HPV-16) in development of cervical cancer in situ (CIS). METHODS Information on ris...

To estimate the risk of human papillomavirus (HPV) infection for cervical malignancies, we conducted a case-control study in Japan. Abnormal cervical cell (366) and normal cell samples (1562) were tested for the presence of HPV DNA using a new PCR-based test (LCR-E7 PCR). When single HPV infections were considered, 26 different HPV types were identified in normal cervices and in low-grade squam...

Abstract Objective To assess the prevalence and distribution of HPV genotypes among Chinese Han women, to explore risk high-grade cervical lesions associated with individual hr-HPV genotypes. Methods Genotyping histopathology data from Multi-Center Screening Trial (CHIMUST) its pilot screening trial, 6 regions across mainland China, were re-analyzed. The physician- self-collected samples 10,867...

Background and Objective: Human papillomavirus (HPV) is one of the possible etiologic factors  in development of esophageal squamous cell carcinoma (ESCC). In this study we aimed to study the  role of HPV in ESCC. Patients and Methods:In this study, 140 cases of ESCC were analyzed for the HPV DNA by  polymerase chain reaction (PCR) using GP5+/GP6+ primers for L1 open reading frame (ORF) to  am...
