Complementary and Innovative Method in Genital HPV Testing for Cervical Cancer Prevention

2020

Abstract Considering actual SARS-COV 2 pandemic, the comfort and time of the female patient’ trend is to minimize the time spent in the doctor’s office, so that auto-testing is a solving problem in this context. This paper aims at the importance of self-collected urine and vaginal samples, since actual studies are showing that is a complementary method in HPV-testing and a screening method for prevention of cervical cancer. Genital HPV infection is responsible for approximately 99% of cervical cancers, and is considered a sexually transmitted disease. Given that eight out of ten patients have at least one episode of HPV infection in their lifetime, there is a need for a method of early dete…

Low rate of oral human papillomavirus (HPV) infection in women screened for cervical HPV infection in Southern Italy: A cross-sectional study of 140 …

2009

Even though the natural history of cervical and oral human papillomavirus (HPV) infection has been investigated intensely, the possibility that HPV may infect both sites in the same subject is not well documented. This study investigated the frequency of concurrent oral and cervical HPV infection in southern Italian women, in the light of some selected socio-behavioral variables. One hundred forty women (mean age: 36 years), with known cervical HPV status, were analyzed for oral HPV. Age, smoking/drinking habits, clinical and socio-behavioral history were assessed by personal interviews. Oral mucosal cells were collected by oral brushing and HPV DNA was sought by the use of nested PCR ampli…

Histological features and ki-67 index in cervical atypical lesions

2008

One of the most frequent challenges in routine diagnostic assessment of cervical biopsies consists of some lesions in which histological features of HPV infection are either inconsistently present or only mildly/focally evident. We named them Atypical Lesions (AL) because differential diagnosis with metaplastic/reactive lesions and LSIL is difficult. It would be important to identify among them those lesions that are really HPV-associated. We studied 52 AL cases to evaluate whether the morphological features and the proliferation index, assessed by Mib1 (Ki67) immunostaining, would be useful to better understand the real nature of AL, with relation to the HPV presence and to the proliferati…

Human papillomaviruses (HPV) are non-enveloped DNA tumor viruses that infect skin and mucosa. The most oncogenic subtype, HPV16, causes various types of cancer, including cervical, anal, and head and neck cancers. During the multistep process of infection, numerous host proteins are required for the delivery of virus genetic information into the nucleus of target cells. Over the last two decades, many host-cell proteins such as heparan sulfate proteoglycans, integrins, growth factor receptors, actin and the tetraspanin CD151 have been described to be involved in the process of infectious entry of HPV16. Tetraspanins have the ability to organize membrane microdomains and to directly influenc…

Caracterización inmunofenotípica del cáncer de cuello uterino asociado a la infección por Virus Papiloma Humano (HPV)

2006

Se llevó a cabo un estudio inmunohistoquímico incluyendo un panel de 18 biomarcadores y un estudio molecular en 81 biopsias de cáncer de cuello uterino (59 carcinomas epidermoides y 19 adenocarcinomas cervicales) diagnosticados en el Servicio de Anatomía Patológica del Hospital Clínico Universitario de Valencia, con la finalidad de realizar la caracterización inmunohistoquímica de esta neoplasia invasora y determinar la presencia de ADN-HPV asociado. El estudio inmunohistoquímico se realizó, en tumores cervicales y tejido cervical benigno como control, mediante la técnica de avidina-biotina, interpretado mediante una escala semicuantitativa. Se determinó la presencia y genotipificación de A…

Estudio molecular del condiloma acuminado: correlación clínica e histopatológica, genotipo del virus del papiloma humano y factores de riesgo asociad…

2015

INTRODUCCIÓN: Los condilomas acuminados(CA) se encuentran entre las enfermedades más comunes de transmisión sexual. Aunque habitualmente se entiende que es el virus del papiloma humano (VPH) de bajo riesgo, genotipos 6 y 11 los que están asociados con el CA, sólo existen un número limitado de estudios publicados que informan de la prevalencia específica del genotipo del VPH. El objetivo de nuestro estudio fue evaluar la prevalencia de genotipos del VPH para un elevado número de casos que involucran tanto a hombres y mujeres y poder evaluar el beneficio potencial de una vacuna cuatrivalente (genotipos 6, 11, 16, y 18) contra el VPH en Valencia (España ) y analizar los factores de riesgo asoc…
