abstract background: cancers are the second most common cause of non-accidental deaths in iran, after cardiovascular mortality. although most cases of esophageal squamous cell carcinoma (escc) in the usa and western populations have been attributed to high levels of exposure to tobacco and alcohol, but in iranian populations the other risk factors especially infectious agents have been postulat...
BACKGROUND HPV infection is common and may cause cancer among men who have sex with men (MSM). Anal HPV infection (HPV+) was found in 85% of HIV-positive (HIV+) and 59% of HIV-negative (HIV-) MSM in Bangkok, central Thailand. As little is known about HPV in this group in northern Thailand, we studied MSM subgroups comprised of gay men (GM), bisexual men (BM), and transgender women (TGW). METH...
OBJECTIVES The assessment of the prevalence of antibodies to human papillomaviruses (HPV) in the healthy population is essential for effective planning of HPV vaccine implementation into the preventive programmes for HPV-associated diseases and for the prospective monitoring of the impact of HPV vaccines in the Czech population. METHODS The seropositivity for HPV-6, 11, 16, 18, 31 and 33 viru...
The correlation of viral factors with cervical cancer was investigated. 27 cervical cancer biopsies and 29 normal cervical scrapings were determined by polymerase chain reaction method for 6 viruses, including human papillomavirus (HPV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), herpes simplex virus (HSV)-1, HSV-2, and human herpes virus (HHV)-8. Among 27 biopsies of cervical cancer, HPV...
BACKGROUND Endemic malaria and helminth infections in sub-Saharan Africa can act as immunological modulators and impact responses to standard immunizations. We conducted a cohort study to measure the influence of malaria and helminth infections on the immunogenicity of the bivalent HPV-16/18 vaccine. METHODS We evaluated the association between malaria and helminth infections, and HPV-16/18 a...
BACKGROUND Human papillomavirus (HPV) infection, particularly with type 16, causes a growing fraction of oropharyngeal cancers, whose incidence is increasing, mainly in developed countries. In a double-blind controlled trial conducted to investigate vaccine efficacy (VE) of the bivalent HPV 16/18 vaccine against cervical infections and lesions, we estimated VE against prevalent oral HPV infecti...
Scientists do not know precisely which elements of the immune system are important in preventing or resolving human papillomavirus (HPV) infections in unvaccinated women. HPV has a battery of immune-evasion mechanisms that include hiding within the host mucosal cells, lowlevel production of late (L) proteins, and inhibition of innate immunity and cellmediated response by early proteins [1]. HPV...
Background and purpose: Human papillomavirus infection is the most important risk factor and necessary cause of cervical cancer. The aim of this study was to determine the genotypes of HPV DNA in cervical carcinoma samples from Shohada and Imam Hossien Hospitals in Tehran, between 1999 and 2008. Materials and methods: After the paraffin alleviation process from the sections needed for HPV typi...
The introduction of vaccination against Human Papillomavirus (HPV) in adolescent girls in 2006 has focused virological surveillance on this age group. As few studies have evaluated HPV infections in young populations, further data are needed in order to improve and extend prophylactic policy and to monitor epidemiological changes. The present study aimed at evaluating overall and type-specific ...
