Persistent infection with high-risk human papillomavirus (HPV) is the main cause of cervical cancer and the prevalence of HPV types varies depending on the geographic region. Therefore, this study assessed the prevalence of HPV types in women with cervical lesions from Sergipe state, Northeastern Brazil. A cross-sectional study was conducted in women with cervical lesions from March to December 2014. These lesions were investigated by PCR and HPV types were identified by DNA sequencing. 432 patients were included, of which 337 patients tested positive for HPV...

INTRODUCTION: Human papillomavirus (HPV) is a common sexually transmitted infection in the United States that can lead to both malignant (high-risk) and benign (low-risk) findings. These low-risk findings include both genital condyloma, anal warts, and adult or juvenile papillomatosis, which are directly attributable to subtypes HPV 6 and HPV 11. We aim to estimate the prevalence of genital wart infections in men in the US population using a nationwide sample. METHODS: The NHANES database was queried for all men aged 18 to 59 years during the years 2013 to 2014...

Directing an antigen to the endoplasmic reticulum (ER) improves the antigen-specific immune response, revealing a potentially useful strategy in cancer immunotherapy using tumor-associated antigens (TAAs). This can be achieved by fusing the antigen to an ER chaperone protein, such as calreticulin (CRT). We previously reported the antitumor response by fusing the CRT signal peptide (SP) and its ER retention sequence (KDEL) to full-length human papillomavirus type 16 (HPV-16) E6 and E7 antigens, obtaining a potent antitumoral effect...

A significant proportion of mucosal squamous cell carcinomas of the head and neck (HNSCC; particularly of the oropharynx) are directly attributable to the human papillomavirus (HPV). The increase in the incidence of HPV-related tumours has been postulated to be due to changing sexual practices in the community. We analysed 136 formalin-fixed paraffin-embedded squamous cell carcinomas from the oral cavity (n=40) and oropharynx (n=96) recruited from the Princess Alexandra Hospital (Brisbane, Australia). Samples were analysed for the presence of HPV DNA using a combination of mucosal HPV general primer GP+ PCR and sequencing; p16INK4a expression was assessed by immunohistochemistry...

Introduction: Primary-prevention by prophylactic vaccination against HPV-related cancers and HPV-based screening programs are based on HPV-type distribution in immunocompetent individuals. HIV-infected women are at high risk of invasive HPV-disease sustained by a broader range of HPV-types and have higher multi-type infection rates than immunocompetent hosts. Methods: This is a cross-sectional analysis of High Risk HPV (HR HPV) type distribution in 805 HIV+ women (HIW) compared with a control group of 1402 immunocompetent HIV- women (SPW) enrolled in the VALHIDATE study in order to define HPV type-specific distribution according to cytology...

Cervical screening with cytology has been the basis for substantial reductions in cervical cancer incidence and mortality in most high-income countries over the last few decades. More recently, there have been two key, parallel developments which have prompted a major re-consideration of cervical screening. The first is the emergence of evidence on the improved sensitivity of human papillomavirus (HPV) DNA testing compared to cytology, and the second is the large-scale deployment of prophylactic vaccination against HPV...

Information on the prevalence and type distribution of human papillomavirus (HPV) among Malaysian women is currently limited. The present study therefore aimed to provide an updated estimate on the prevalence and type distribution of HPV among Malaysian women with and without cervical cancer. Total DNA was isolated from the cervical cell specimens of 185 histopathologically confirmed cervical cancer patients and 209 cancer-free healthy females who were tested negative in a recent Pap test. Viral-specific DNA was subsequently amplified with biotinylated primers and hybridized to HPV type-specific probes via a proprietary "flow-through hybridization" process for determination of HPV genotype...

Cervical cancer and cervical intraepithelial neoplasia (CIN) are well-known outcomes of a human papillomavirus (HPV) infection. Viral oncogenes expressions like E6, E7, and, recently recognized E5, lead to HPV-related malignant progression. Although HPV prevention by powerful vaccines against most frequent and oncogenic genotypes is feasible, current treatment against cervical neoplasia is distant from an ideal one. In addition, late diagnosis is commonly associated with a poor prognosis. On top of that, radiotherapy, chemotherapy, or surgery are less effective in high-grade lesions...

BACKGROUND: Developed countries, such as the USA, have achieved significant decreases in cervical cancer burden since the introduction of Pap smear-based programs in the 1960s. Due to implementation barriers and limited resources, many countries in sub-Saharan Africa (SSA) have been unable to attain such reductions. The purpose of this review is to evaluate implementation strategies used to improve the uptake and sustainability of cervical cancer prevention programs in SSA. METHODS: A reviewer (LJ) independently searched PubMed, Ovid/MEDLINE, Scopus, and Web of Science databases for relevant articles with the following search limits: English language, peer reviewed, and published between 1996 and 2017...
