[Vaccination against papillomavirus : arguments and evidence of effectiveness].
2020
Vaccination against papillomavirus: arguments and evidence of effectiveness. Vaccination against human papillomavirus is a major advance in the prevention of cervical cancer. Evidence of its effectiveness has accumulated over the past thirty years since basic research has demonstrated the ability of viral pseudoparticles to induce immune responses in animals. Large human clinical trials followed to demonstrate the safety and efficacy of vaccination against targeted HPV infections and their associated lesions. After its approval and marketing the vaccine efficacy was measured at the level of entire populations, confirming its effectiveness and medical interest. Today, models predict a possib…
Overview of the benefitsand potential issues of the nonavalent HPV vaccine
2017
HPV-related diseases affect anogenital and oropharyngeal regions, heavily affecting the psychosexual dimension of both male and female individuals. HPV vaccination programs based on a bivalent or quadrivalent vaccine have opened broad perspectives for primary prevention. A nonavalent HPV vaccine (9vHPV), covering nine genotypes (HPV6, HPV11, HPV16, HPV18, HPV31, HPV33, HPV45, HPV52, and HPV58), might provide further improvement in terms of direct protection. In the present report, efficacy and safety data from 9vHPV vaccine development programs are examined. Efficacy data come from a pivotal trial, which was conducted among women aged 16–26 years randomly assigned to receive either the 9vHP…
Human papilloma virus infection and vaccination: Pre-post intervention analysis on knowledge, attitudes and willingness to vaccinate among preadolesc…
2020
In recent years, vaccination coverage rates against Human Papilloma Virus (HPV) in Europe have shown a decreasing trend and remain below the required standard. The present study aims to assess knowledge and attitudes regarding HPV infection and vaccination among a representative sample of preadolescents of Palermo, Italy. A survey was carried out throughout two questionnaires, before and after carrying out an educational intervention scheduled during school hours. A total of 1702 students attending first-grade secondary schools of the province of Palermo were enrolled (response rate 68.9%). Students attending third classes (adj OR = 1.18
Penile, Uretral and Seminal Sampling for Diagnosis of Human Papillomavirus Infection in Men.
2006
ABSTRACT Methods that used specimens from three genital sites (penile brushing [PB], urethral brushing [UB], and the retrieval of semen [SE]) from 50 men were examined for human papillomavirus (HPV) DNA detection. The rates of detection by PB, UB, SE, PB and UB, and PB and SE were 88.9%, 50.0%, 33.3%, 100%, and 97.2%, respectively. The use of PB and UB appears to be the most accurate method; as an alternative to UB, the use of SE with PB could be used to improve the rate of HPV DNA detection in men.
Distribution and density of CD1a+ and CD83+ dendritic cells in HPV-associated laryngeal papillomas.
2009
Summary Background Respiratory papillomatosis associated with human papilloma virus (HPV) infection is the most common benign laryngeal neoplasm. The age of patients at disease onset, HPV type, number of surgeries are well known prognostic factors of the disease course. The correlation between dendritic cell (DC) density in tumor tissue and clinical prognosis was established. Aim The aim of our study was to estimate the density of DC in laryngeal papillomas associated with HPV types 6/11 infection and to evaluate the relationship between the number of DC and the disease severity. Materials and methods Our study included 40 randomly selected biopsy specimens from patients with HPV-positive l…
Brushing of Oral Mucosa for Diagnosis of HPV Infection in Patients with Potentially Malignant and Malignant Oral Lesions
2006
Introduction: Adequate brushing of oral mucosa is important for accurate human papillomavirus (HPV) detection in potentially malignant (oral leukoplakia [OL], oral lichen planus [OLP]) and malignant (oral squamous cell carcinoma [OSCC]) lesions. Since various factors may limit the adequacy of oral brushing and, consequently, the accuracy of HPV detection, modified sampling procedures should be evaluated for their effect on HPV frequency and/or types detected. Aim: To compare the HPV frequency in samples obtained by brushing the lesion site with the frequency in samples obtained by brushing an apparently normal adjacent site. The correlation between HPV frequency and keratinization of the si…

Human papillomavirus in saliva of patients with oral squamous cell carcinoma.
2008
Objective: The aim of this study was to evaluate the presence of human papillomavirus (HPV) in saliva rinses of patients with oral squamous cell carcinoma (OSCC)and to analyze the possibility of using saliva as a diagnostic method for screening high-risk patients. Study design: The saliva sample of 22 patients with oral squamous cell carcinoma and 20 age-sex matched healthy controls were obtained. The presence of HPV 6, 11, 16, 18, 31, and 33 was evaluated by polymerase chain reaction (PCR). Results: In 40.9% of the patients and in 25% of the controls, the saliva was shown to be positive for HPV. In 27.3% of the patients and in 20% of the controls, the saliva was shown to be positive for HP…
Detection of Human Papillomavirus in Nonmelanoma Skin Cancer Lesions and Healthy Perilesional Skin in Kidney Transplant Recipients and Immunocompeten…
2013
Abstract Background The influence of human papillomavirus (HPV) on the development of nonmelanoma skin cancer (NMSC) is a topic of debate. HPV types from the beta genus (HPV-β) have been most frequently associated with the development of skin cancer. Objectives To analyze the prevalence and range of HPV types in NMSC lesions and healthy perilesional skin in immunodepressed and immunocompetent patients and to evaluate the influence of various clinical factors on the prevalence of HPV in skin cancer. Methods Nested polymerase chain reaction and sequencing were used to detect HPV in 120 NMSC samples obtained by biopsy from 30 kidney transplant recipients and 30 immunocompetent patients. In all…
Prevalence and distribution of human papillomavirus findings in swab specimens from gynaecology clinics of the east coast of Spain.
2010
The objective of this study was to determine the prevalence of human papillomavirus (HPV) among females in the east coast of Spain. A total of 1956 women visiting gynaecology clinics for routine check-ups were included in the study. Swabs were analyzed for HPV DNA by consensus polymerase chain reaction followed by direct sequencing. The overall HPV prevalence was 12.99%. HPV vaccine types 6, 11, 16 and 18 were detected in 6.13% of female participants.
