Prevalence of HPV infection in racial-ethnic subgroups of head and neck cancer patients

2017

Abstract The landscape of human papillomavirus (HPV) infection in racial/ethnic subgroups of head and neck cancer (HNC) patients has not been evaluated carefully. In this study, a meta-analysis examined the prevalence of HPV in HNC patients of African ancestry. Additionally, a pooled analysis of subject-level data was also performed to investigate HPV prevalence and patterns of p16 (CDNK2A) expression amongst different racial groups. Eighteen publications (N = 798 Black HNC patients) were examined in the meta-analysis, and the pooled analysis included 29 datasets comprised of 3129 HNC patients of diverse racial/ethnic background. The meta-analysis revealed that the prevalence of HPV16 was h…

Epstein-Barr virus infection as a trigger of autoimmune hepatitis: Case report

2008

Abstract: The study underlines the importance of the differential diagnosis between primary Epstein- Barr virus EBV associated hepatitis with features of autoimmunity, in which there is a direct pathogenetic role of the virus, and EBV related autoimmune hepatitis, in which EBV could act as the trigger of the immune-mediated damage with probable differences between the two conditions with regard to the prognosis and the responsiveness to immunosuppressive treatment. Moreover we hypothesise that the favourable outcome in our patient, better than the most of autoimmune hepatitis cases, may be related either to the moderate necroinflammatory activity and to the low level of fibrosis at the begi…

Immune status towards Epstein-Barr virus in a group of Sicilian children.

1989

The prevalence of antibodies to Epstein-Barr virus-determined antigens was studied in 17 children with acute infectious mononucleosis (IM) and in 263 children hospitalized for diseases unrelated to EBV infection. Antibodies against Epstein-Barr viral capsid antigens (VCA) were observed in 173 patients of the control group (66%), but 58 of them (33,5%) had not yet developed antibodies against Epstein-Barr virus-associated nuclear antigen (EBNA). IgM-specific antibodies were not found in any of the children of the control group but were present in all of the 17 patients with IM. The rates of positivity for IgA anti-VCA and IgG anti-early antigen (EA) were similar in all age groups. Anti-viral…

Giant cell arteritis associated with chronic active Epstein-Barr virus infection

2013

Giant cell arteritis is an inflammatory vasculopathy that preferentially affects medium-sized and large arteries. A viral cause has been suspected but not confirmed in polymyalgia rheumatica and giant-cell arteritis. We report the case of a 81-year-old female who suffered from chronic active Epstein-Barr virus infection and developed giant cell temporal arteritis.

Evolución serológica de la primoinfección por el virus de Epstein-Barr en niños

2019

Existen pocos estudios longitudinales sobre la evolución serológica tras la primoinfección por el VEB en la infancia. La interpretación de la respuesta serológica en los niños no es fácil, ya que la infección suele cursar de manera oligosintomática en los mas pequeños, la sensibilidad de los anticuerpos heterófilos es baja y la serología puede dar falsos negativos y positivos por reacciones cruzadas con otros virus. La ausencia de respuesta serológica en algunas personas, nos pone en la situación de tener que interpretar perfiles serológicos atípicos de los que se desconoce su repercusión. El objetivo de este estudio fue describir las características clínicas, epidemiológicas y la evolución…
